Referring to
The main chamber 110 serves to contain water. To this end, the main chamber 110 may include a main space for accommodating water. The suction pipe 121 may be provided on the bottom surface of the main chamber 110. The suction pipe 121 may provide a movement path for water sucked into the main space of the main chamber 110. The bottom surface of the main chamber 110 may be parallel to a water surface, and the cross-sectional area of the main chamber 110 may be formed to be larger than that of the suction pipe 121. The main chamber 110 may accommodate water sucked through the suction pipe 121.
The main chamber 110 may be fixed to the ground by the support part 111. In the present invention, the ground may be understood as the top surface of the ground (GR) supporting river water or stream water at a point where the river water or the stream water is located. As a result, in the present invention, the power generation apparatus 10 is installed at a point where river water or stream water is located, and generates power. The support part 111 serves to fix the main chamber 110 to the ground GR at the point where river water or stream water is located so that the bottom surface of the main chamber 110 is spaced apart from the ground GR by a predetermined distance and the bottom surface of the main chamber 110 and the suction pipe 121 are placed below the surface of the river water or the stream water. Hereinafter, the point at which river water or stream water is located and power is generated by the power generating apparatus 10 of the present invention is referred to as a power generation point.
The main chamber 110 may have a long shape in a direction perpendicular to the ground. Hereinafter, a direction perpendicular to the ground is referred to as a first direction I, a direction perpendicular to the first direction I and parallel to the ground is referred to as a second direction II, and a direction perpendicular to the first direction I and the second direction II is referred to as a third direction III.
Alternatively, according to some embodiments of the present invention, the main chamber 110 may have a wide shape parallel to the ground. That is, the external shape of the main chamber 110 may be longer in the second direction II and in the third direction III than in the first direction I. Hereinafter, the main chamber 110 having a long shape in the first direction I will be mainly described.
Although
The discharge pipe 130 may be provided on the ceiling surface of the main chamber 110. The discharge pipe 130 may provide a path for discharging air, accommodated in the main space of the main chamber 110, to the outside. The cross-sectional area of the ceiling surface of the main chamber 110 may be formed to be larger than the cross-sectional area of the discharge pipe 130. The pressure pump 140 may be connected to one end of the discharge pipe 130. The pressure pump 140 serves to generate pressure and discharge air in the main space out of the main chamber 110 through the discharge pipe 130 provided on the ceiling surface of the main chamber 110. More specifically, air present in the upper space of the main space may be discharged out of the main chamber 110 through the discharge pipe 130 by the pressure of the pressure pump 140.
As air present in the upper space of the main space is discharged out of the main chamber 110 by the pressure pump 140, water may be sucked into the main chamber 110 through the suction pipe 121. When the main chamber 110 is installed at the power generation point, the bottom surface of the main chamber 110 and the suction pipe 121 may be located below the surface of the water. That is, a portion of the lower portion of the main chamber 110 may be submerged in water. Accordingly, in the case where air present in the upper space of the main space is discharged out of the main chamber 110 by the pressure pump 140, as pressure inside the main chamber 110 is reduced compared to the external pressure based on the bottom surface of the main chamber 110 and the suction pipe 121, water may be sucked into the main chamber 110 through the suction pipe 121 and rise up to the top surface of the main chamber 110.
The suction valve 122 may be provided in the suction pipe 121. The intake valve 122 may selectively open and close the intake pipe 121. When the suction valve 122 opens the suction pipe 121, water may be sucked into the main chamber 110 through the suction pipe 121. When the suction valve 122 closes the suction pipe 121, the movement of water through the suction pipe 121 may be blocked.
The spout part 170 is provided on a side of the main chamber 110, and serves to spout water, sucked by the pressure pump 140 and accommodated in the main space, out of the main chamber 110.
The spout part 170 includes a spout pipe 171 and a spout adjustment unit 172. The spout pipe 171 may provide a path for water spouted out of the main chamber 110. One side of the spout pipe 171 may be connected to the side of the main chamber 110. Accordingly, the spout pipe 171 may provide a path for water discharged from the side of the main chamber 110 and connected to the power generation unit 180.
The spout adjustment unit 172 serves to adjust the amount of water spouted through the spout pipe 171. The spout adjustment unit 172 may close the spout pipe 171 so that no water is spouted, may partially open the injection pipe 171 so that a small amount of water is spouted, or may completely open the spout pipe 171 so that a large amount of water is spouted.
A spout hole through which water is spouted from the spout pipe 171 may face the ground. Accordingly, water spouted from the spout part 170 may fall through a connection pipe (not shown) connected to the power generation part 180 or toward the ground directly from the spout part 170.
The power generation unit 180 serves to generate power with the pressure of water sprayed by the spout part 170. The power generation unit 180 includes a rotation unit 181 and a power generation unit 182. The rotation unit 181 may be rotated by the force of water spouted by the spout part 170. In order to receive the power of water, the rotation unit 181 may have a plurality of blades. As water exerts impact on one-side surfaces of the blades, the rotation unit 181 may be rotated. In particular, in the present invention, the spout part 170 may be provided above the rotation unit 181. The rotation unit 181 may be rotated by the force of water falling from the spout part 170.
The power generation unit 182 serves to convert the rotational force of the rotation unit 181 into electric power. A rotation shaft 183 may be provided between the rotation unit 181 and the power generation unit 182 to transmit the rotational force of the rotation unit 181 to the power generation unit 182.
A part of the rotation shaft 183 may be accommodated inside the power generation unit 182. A coil (not shown) may be wound around the rotation shaft 183 accommodated inside the power generation unit 182, and a permanent magnet (not shown) may be provided inside the power generation unit 182 along the edge of the coil. When the rotating shaft 183 is rotated, a flow of current may be generated through the coil. Since the detailed internal structure of the power generation unit 182 is out of the scope of the present invention, a detailed description thereof will be omitted.
The power generated by the power generation unit 182 may be delivered to and consumed in a power consumption site (not shown), or may be delivered to and stored in a power storage site (not shown).
The inlet pipe 150 may be provided on the ceiling surface of the main chamber 110. The inlet pipe 150 may provide a path for external air introduced into the main space of the main chamber 110. The inlet valve 160 may be provided in the inlet pipe 150. The inlet valve 160 may selectively open and close the inlet pipe 150. When the inlet valve 160 opens the inlet pipe 150, external air may be introduced into the main chamber 110 through the inlet pipe 150. When the inlet valve 160 closes the inlet pipe 150, the inflow of external air through the inlet pipe 150 may be blocked.
The inlet pipe 150 serves to make the spout of water through the spout part 170 more smooth. When the distance to the surface of the water accommodated in the main space of the main chamber 110 based on the surface of water present around the main chamber 110 at the power generation point is not sufficiently long (for example, when the distance is less than 10 m), the spout of water through the spout hole may not be smooth even when the spout hole is opened. The internal and external pressures of the main chamber 110 are similarly formed such that water cannot be smoothly discharged through the spout hole.
When the inlet pipe 150 is opened and external air flows into the main chamber 110, the pressure inside the main chamber 110 becomes higher than that of the outside, so that water can be smoothly discharged through the spout hole.
The control device 190 serves to control the suction valve 122, the pressure pump 140, the inlet valve 160, and the spout adjustment unit 172 according to input control commands. For example, when a control command to accommodate water in the main chamber 110 is input, the control device 190 may control the suction valve 122 so that the suction pipe 121 is opened, may operate the pressure pump 140, may control the inlet valve 160 so that the inlet pipe 150 is closed, and may control the spout adjustment unit 172 so that the spout pipe 171 is opened. Furthermore, when a control command to generate power is input, the control device 190 may control the suction valve 122 so that the suction pipe 121 is closed, may stop the operation of the pressure pump 140, may control the inlet valve 160 so that the inlet pipe 150 is opened, and may control the spout adjustment unit 172 so that the spout pipe 171 is opened.
Furthermore, the control device 190 may perform a crossing command for a control command to accommodate water and a control command to generate power.
The control device 190 may be disposed adjacent to the main chamber 110, or may be disposed remotely from the main chamber 110. A user may input a control command to the control device 190. The control device 190 may control the suction valve 122, the pressure pump 140, the inlet valve 160, and the spout adjustment unit 172 according to input control commands input from the user. In this case, the user may input a detailed adjustment command to the spout adjustment unit 172. For example, the user may input an adjustment command specifying the degree of opening of the spout pipe 171, and the control device 190 may operate the spout adjustment unit 172 so that the spout pipe 171 is opened according to the input adjustment command.
The auxiliary chamber 200 is supported by the main chamber 110, is provided with an auxiliary space for accommodating water, and serves to receive water from the main chamber 110 or supply water to the main chamber 110. Part of the water introduced into the main chamber 110 may move to the auxiliary chamber 200 and be accommodated in the auxiliary chamber 200, and the water accommodated in the auxiliary chamber 200 may be supplied to the main chamber 110 and be used for power generation.
For the coupling between the main chamber 110 and the auxiliary chamber 200, the main chamber 110 may have main coupling protrusions 112, and the auxiliary chamber 200 may include auxiliary coupling slits 210. The main chamber 110 and the auxiliary chamber 200 may be engaged with each other using the main coupling protrusions 112 and the auxiliary coupling slits 210, and additional coupling using a bolt or welding may be performed thereon.
The main chamber 110 may include main outlets 113 and main inlets 114. The main outlets 113 may provide a passage for the supply of water to the auxiliary chamber 200. The main inlets 114 may provide a passage for the reception of water from the auxiliary chamber 200. The main outlets 113 may be disposed above the main inlets 114.
The auxiliary chamber 200 may include a first auxiliary inlet 221, a second auxiliary inlet 222, a first auxiliary outlet 231, a second auxiliary outlet 232, and auxiliary coupling protrusions 240.
The first auxiliary inlet 221 may be connected to the main outlet 113 and may provide a passage for the reception of water from the main chamber 110. The first auxiliary outlet 231 may be connected to the main inlet 114, and may provide a passage for the supply of water to the main chamber 110.
When the auxiliary chamber 200 is coupled to the main chamber 110, the main outlet 113 of the main chamber 110 and the first auxiliary inlet 221 of the auxiliary chamber 200 may be connected to each other, and the main inlet 114 of the main chamber 110 and the first auxiliary outlet 231 of the auxiliary chamber 200 may be connected to each other. When the level of the water accommodated in the main chamber 110 reaches the main outlet 113, the water accommodated in the main chamber 110 is supplied to the auxiliary chamber 200 through the main outlet 113 and the first auxiliary inlet 221. Furthermore, when electric power is generated, water accommodated in the auxiliary chamber 200 may be supplied to the main chamber 110 through the first auxiliary outlet 231 and the main inlet 114.
The first auxiliary inlet 221 provided in the auxiliary chamber 200 may provide a passage for the reception of water from another auxiliary chamber 200, and the first auxiliary outlet 231 may provide a passage for the supply of water to the other auxiliary chambers 200. The auxiliary chamber 200 may be connected to the other auxiliary chamber 200, and may exchange water with the other auxiliary chamber 200.
The second auxiliary outlet 232 may provide a passage for the supply of water to another auxiliary chamber 200, and the second auxiliary inlet 222 may provide a passage for the reception of water from the other auxiliary chamber 200. The second auxiliary outlet 232 may be disposed above the second auxiliary inlet 222.
When the auxiliary chamber 200 is coupled to another auxiliary chamber 200, the second auxiliary outlet 232 of the auxiliary chamber 200 and the first auxiliary inlet 221 of the other auxiliary chamber 200 may be connected to each other, and the second auxiliary inlet 222 of the auxiliary chamber 200 and the first auxiliary outlet 231 of the other auxiliary chamber 200 may be connected to each other. When the level of the water accommodated in the auxiliary chamber 200 reaches the second auxiliary outlet 232, water accommodated in the auxiliary chamber 200 may be supplied to the other auxiliary chamber 200 through the second auxiliary outlet 232 of the auxiliary chamber 200 and the first auxiliary inlet 221 of the other auxiliary chamber 200. Furthermore, when power is generated, water accommodated in the other auxiliary chamber 200 may be supplied to the auxiliary chamber 200 through the first auxiliary outlet 231 of the other auxiliary chamber 200 and the second auxiliary inlet 222 of the auxiliary chamber 200.
The auxiliary coupling protrusions 240 may be used for coupling with other auxiliary chambers 200. The auxiliary chamber 200 and the other auxiliary chamber 200 are coupled to each other by engaging the auxiliary coupling protrusions 240 provided on the auxiliary chamber 200 and the auxiliary coupling slits 210 provided in the other auxiliary chamber 200 with each other.
Referring to
While the auxiliary chamber 200 descends from a location above the main chamber 110, the main coupling protrusions 112 of the main chamber 110 and the auxiliary coupling slits 210 of the auxiliary chamber 200 may be engaged with each other. To more securely couple the main chamber 110 and the auxiliary chamber 200 to each other after the main coupling protrusions 112 and the auxiliary coupling slits 210 have been engaged with each other, coupling means such as a bolt or welding may be used.
Referring to
Hereinafter, the auxiliary chamber 200 disposed closer to the main chamber 110 is referred to as a first auxiliary chamber 200, and the auxiliary chamber 200 disposed farther from the main chamber 110 is referred to as a second auxiliary chamber 200.
As the second auxiliary chamber 200 descends from a location above the first auxiliary chamber 200, the auxiliary coupling protrusions 240 of the first auxiliary chamber 200 and the auxiliary coupling slits 210 of the second auxiliary chamber 200 are engaged with each other. To more securely couple the first auxiliary chamber 200 and the second auxiliary chamber 200 to each other after the auxiliary coupling protrusions 240 and the auxiliary coupling slits 210 have been engaged with each other, a coupling means such as a bolt or welding may be used.
Referring to
The main chamber 110 may include a plurality of sides. Auxiliary chambers 200 may be coupled to the respective sides. Furthermore, the second auxiliary chamber 200 may be coupled to the first auxiliary chamber 200 coupled to the main chamber 110. For example, when a natural or artificial object capable of supporting the auxiliary chamber 200, such as bedrock or the foot of a mountain, is provided near the power generation point where the power generation device 10 is installed, it may be possible to connect a plurality of auxiliary chambers side by side in a direction substantially parallel to the ground 200. At least one of the plurality of auxiliary chambers 200 connected side by side is supported by the supporting means, so that the power generation device 10 can stably maintain its posture.
Whether to install the auxiliary chamber 200 may be determined by taking into consideration an operation environment and an installation environment in combination. For example, when it is determined that power generation using only the main chamber 110 is insufficient, the auxiliary chamber 200 may be installed. Furthermore, when an additional auxiliary chamber 200 needs to be installed after the auxiliary chamber 200 has been installed, the additional auxiliary chamber 200 may be coupled to the main chamber 110 or to the previously installed auxiliary chamber 200.
Furthermore, after the auxiliary chamber 200 has been installed, it may be easily removed. That is, the auxiliary chamber 200 may be removed from the main chamber 110 by moving the auxiliary chamber 200 upward with respect to the main chamber 110. Alternatively, the second auxiliary chamber 200 may be removed from the first auxiliary chamber 200 by moving the second auxiliary chamber 200 upward with respect to the first auxiliary chamber 200.
Referring to
When the external pressure of the main chamber 110 exceeds the internal pressure based on the main inlets 114, the main opening/closing parts 115 may open the main inlets 114. In contrast, when the external pressure of the main chamber 110 is equal to or lower than the internal pressure, the main opening/closing parts 115 may close the main inlets 114.
The main opening/closing parts 115 may each be provided in the form of a door, or may each be provided in the form of a check valve. Due to the main opening/closing parts 115, the movement of water from the main chamber 110 to the auxiliary chamber 200 through the main inlet 114 may be blocked, and the movement of water from the auxiliary chamber 200 to the main chamber 110 may be allowed.
Referring to
When the external pressure of the auxiliary chamber 200 exceeds the internal pressure based on the second auxiliary inlet 222, the auxiliary opening/closing part 250 may open the second auxiliary inlet 222. In contrast, when the external pressure of the auxiliary chamber 200 is equal to or lower than the internal pressure, the auxiliary opening/closing part 250 may close the second auxiliary inlet 222.
The auxiliary opening/closing part 250 may be provided in the form of a door, or may be provided in the form of a check valve. Due to the auxiliary opening/closing part 250, the movement of water from the first auxiliary chamber 200 to the second auxiliary chamber 200 through the second auxiliary inlet 222 may be blocked, and only the movement of water from the second auxiliary chamber 200 to the first auxiliary chamber 200 may be allowed.
Referring to
Water may be present in the upper part of the ground GR. The position of the main chamber 110 may be determined such that the bottom surface and the suction pipe 121 are submerged in water. Furthermore, the posture of the main chamber 110 may be determined such that the long axis of the main chamber 110 is parallel to a direction perpendicular to the ground, i.e., the first direction I.
Referring to
As the pressure pump 140 operates, air present in the upper part of the main space may be discharged through the discharge pipe 130. Accordingly, the internal pressure of the main space becomes lower than the external pressure of the main space, and water may be sucked through the suction pipe 121 due a pressure reduction action attributable to the pressure difference. In this case, the suction valve 122 may open the suction pipe 121.
As shown in
The suction of water may be performed until the surface of the water in the main space reaches the main outlets 113.
Referring to
When the level of water accommodated in the main chamber 110 reaches the main outlet 113, water in the main chamber 110 may be supplied to the auxiliary chamber 200. Even while the water in the main chamber 110 is supplied to the auxiliary chamber 200, the internal pressure of the main chamber 110 is higher than the external pressure based on the main inlets 114, so that the main opening/closing parts 115 may keep the main inlets 114 closed.
Referring to
Water spouted from the spout pipe 171 may fall and reach the rotation unit 181 of the power generation unit 180. The rotation unit 181 is rotated by the falling water, and the rotational force of the rotating unit 181 may be transmitted to the power generating unit 182. The power generation unit 182 may convert the transmitted rotational force into electric power. The amount of power produced by the power generation unit 182 may vary depending on the degree of opening of the spout pipe 171 adjusted by the spout adjustment unit 172.
For the generation of power, water in the main chamber 110 may first be used, and then water in the auxiliary chamber 200 may be used. As shown in
Referring to
When the surface of the water accommodated in the first auxiliary chamber 200 reaches the first auxiliary outlets 231, the water in the first auxiliary chamber 200 may be supplied to the second auxiliary chamber 200. Even while the water in the first auxiliary chamber 200 is supplied to the second auxiliary chamber 200, the internal pressure of the first auxiliary chamber 200 is higher than the external pressure based on the second auxiliary inlet 222, so that the auxiliary opening/closing part 250 may keep the second auxiliary inlet 222 closed.
As described above, when water is sucked through the suction pipe 121, the sucked water may primarily be accommodated in the main chamber 110, and may then be accommodated in the first auxiliary chamber 200 coupled to the main chamber 110. Furthermore, when the level of water accommodated in the first auxiliary chamber 200 reaches the second auxiliary outlet 232, water may be accommodated in the second auxiliary chamber 200 coupled to the first auxiliary chamber 200. That is, the auxiliary chamber 200 located closer to the main chamber 110 may receive water preferentially. Due to this, load may be preferentially exerted on the auxiliary chamber 200 closer to the main chamber 110. In other words, a case in which the load of the auxiliary chamber 200 farther from the main chamber 110 is higher than that of the auxiliary chamber 200 closer to the main chamber 110 may be prevented, and thus the posture of the power generation device 10 can be maintained in a balanced manner.
Meanwhile, when although not shown, the level of water accommodated in the first auxiliary chamber 200 closer to the main chamber 110 becomes equal to the level of water accommodated in the second auxiliary chamber 200 farther from the main chamber 110, the pressure of the first auxiliary chamber 200 and the pressure of the second auxiliary chamber 200 may become equal to each other, and the auxiliary opening/closing part 250 may open the second auxiliary inlet 222. Due to this, water in the second auxiliary chamber 200 may be introduced into the first auxiliary chamber 200 through the second auxiliary inlet 222 of the first auxiliary chamber 200 and the first auxiliary outlet 231 of the second auxiliary chamber 200.
Referring to
The vortex generation part 300 is disposed adjacent to the discharge pipe 130, and serves to cause air in the main space to generate a vortex and flow into the discharge pipe 130. The vortex generation part 300 may be generally provided in a cone shape. Air in the main space is introduced into the vortex generation part 300 through an air inlet provided in the vortex generation part 300, which generates a vortex that spreads from the narrow entrance of the cone-shaped vortex generation part 300 to the wide edge thereof.
In order to more smoothly generate a vortex, the discharge pipe 130 may include an extension portion 131 extending in the direction of the edge wing of a vortex. A vortex may be generated by the vortex generation part 300 when the sufficient suction force of air is provided by the pressure pump 140. As the vortex is generated, the air accommodated in the main chamber 110 may be discharged more smoothly.

Referring to
The chamber of the auxiliary power generation apparatus has the same shape as the auxiliary chamber of the main power generation apparatus. The inflow of water does not depend on the operation of the pressure pump at the air outlet, but the water stored in the auxiliary chamber is supplied to generate power. The water in the auxiliary power generation apparatus may be filled upward up to the height of the auxiliary chamber by the pressure of the water in the auxiliary chamber. The inflow passage of water needs to be located at a location higher than the sprout hole. When the auxiliary power generation apparatus does not generate power, all control devices are closed. When water is introduced, the air inlet and the water inlet passage of the main power generation apparatus and the air inlet present at the top of the auxiliary power generation apparatus are opened, and the sprout hole is closed. During the generation of power, the water inlet passage is closed, and the air inlet and the sprout hole are opened. In this case, when the water level of the auxiliary chamber is higher than the water level of the chamber of the auxiliary power generation apparatus, the generation of power may be continued by opening the air inlet, the water inlet passage, and the spout hole of the main power generation apparatus.
The inflow of water into the auxiliary power generation apparatus may be repeatedly performed by opening the air inlet of the main power generation apparatus and the air inlet and water inflow passage of the auxiliary generator and closing the sprout hole.
Meanwhile, the main power generation apparatus may be installed high in order to install the remote auxiliary power generation apparatus at a high location.
When the main power generation apparatus is installed high, the air outlet installed in the upper part of the main power generation apparatus may be installed below the chamber as shown in the drawing to observe how the water level inside the chamber changes with respect to the pressure of the air outlet. In this case, it can be seen that the water level (B) inside the chamber stops while being in pressure balance with the level (B) of the water filled in the air discharge pipe inside the chamber and the level (A) of the water filled in the air discharge pipe outside the chamber. Furthermore, it can be seen that the water level (B) inside the chamber stops while being in pressure balance with the water level (b) filled in the air discharge pipe inside the chamber and the water level (a) filled in the air discharge pipe outside the chamber even when the water level in the air discharge pipe is low, as in the case of the water level (b) filled in the air discharge pipe inside the chamber and the water level (a) filled in the air discharge pipe outside the chamber. As shown below, it can be seen that the water level (B) inside the chamber stops while being in pressure balance with the lower water level in the air discharge pipe even when the water level (B) inside the chamber is higher.
