DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 and 2, the hydraulic power generation device of the present invention comprises a case 1 which has a space 11 defined therein and a water passage unit 2 is located in the space 11. In this embodiment, there are at least two water passage units 2, and each water passage unit 2 has a high end and a low end. Taken one of the two water passage units 2 as an example to be described, the water passage unit 2 comprises a first passage 21 and a second water passage 22 which is located below the first passage 21. The first passage 21 is an inclined passage and has a low end and a high end, and the second passage 22 is an inclined passage and has a low end and a high end. The low end of the first passage 21 is located corresponding to the high end of the second passage 22. The first and second passages 21, 22 are inclined toward different directions.

Multiple water turbines 3 are located above the water passage unit 2, and the multiple water turbines 3 are inclinedly arranged along the water passage unit 2. A bottom of each water turbine 3 is located within the water passage unit 2. Each water turbine 3 is connected with an electric power generator 5 which is connected with an electric power storage unit 6. The electric power generator 5 and the electric power storage unit 6 are located outside of the case 1. A pump 7 is located in the bottom of the space 11 of the case 1. The pump 7 is connected to the electric power storage unit 6 and a conductive wire connected to a mains power supply or a power source of a generator. The pump 7 is connected to a first end of a pipe 71, a second end of the pipe 71 extends to a first opening 121 of the case 1 and is located high end of the first passage 21 of the water passage unit 2.

Multiple containers 4 are located beneath the water passage unit 2 and located corresponding to the water turbines 3 respectively. Each container 4 has a room 41 defined therein. The water passage unit 2 has an inlet 23 and an outlet 24 located corresponding to each of the containers 4. Each of the water turbines 3 is located between the inlet 23 and the outlet 24 of the container 4 corresponding to the water turbine 3. The inlet 23 and the outlet 24 communicate with the room 41 of the container 4 corresponding thereto. Each of the inlets 23 and the outlets 24 has a seal 25 connected thereto.

Accordingly, when the present invention is implemented, a pipe connected to a water source is arranged at the first opening 121 of the case 1 so that water can be injected by the pipe into the space 11 of the case 1. The space 11 is filled with a certain height of water. When the water level reaches a required level, the injection of water is stopped, and the water level within the space 11 must be higher than the pump 7. When the pump 7 is activated, power is supplied to the pump 7 by a mains power supply or a power source of a generator through a conductive wire so that the water in the space 11 is pumped to the upper portion of the space 11 via the pipe 71, and the water flows to the high end of the first passage 21. The water then flows downward along the first passage 21 and toward the low end of the first passage 21. The water flows to the high end of the second passage 22 via the low end of the first passage 21, and the water flows downward along the second passage 22 and toward the low end of the second passage 22. The water flows downward along the third passage, the fourth passage (if available) and so on. The water flows back to the initial water level in the case 1. The water is again pumped by the pump 7 to go through the cycle mentioned again.

When the water flows downward, the water turbines 3 are driven and rotated so as to activate the electric power generators 5 that are connected with the water turbines 3 so as to generate electric power which is transported to the electric power storage unit 6. The electric power stored in the electric power storage unit 6 can be supplied for driving the pump 7. It is set that power supplied by a mains power supply or a power source of a generator to the pump 7 is stopped when a preset power capacity is received by the electric power storage unit 6, and then power is supplied by the electric power storage unit 6 to the pump 7 directly. Due to that the present invention is provided with a plurality of water turbines 3, each water turbine 3 will be driven to rotate when water flows through each water turbine 3, and mechanical energy can be converted into electric energy by the electric power generator 5 connected to each water turbine 3. Therefore, the electric energy generated by the plurality of water turbines 3 can not only be supplied for driving the pump 7 but also be supplied to be stored in the electric power storage unit 6 for industrial or livelihood use.

As shown in FIG. 3 when one of the water turbines 3 or the electric power generators 5 needs to be repaired or maintained, the seals 25 of the inlet 23 and the outlet 24 of the container 4 correspondent to the damaged water turbine 3 or the electric power generator 5 are opened. The water enters into the inlet 23 and the room 41 of the container 4, and flows out from the outlet 24 and back to the water passage unit 2 to continuously drive the rest of the water turbines 3. Therefore, the technician can access the damaged water turbine 3 or the electric power generator 5 while the hydraulic power generation device is still in operation. It is noted that the hydraulic power generation device does not need to be shut off while maintaining the damaged water turbine 3 or the electric power generator 5.

As shown in FIG. 4 which shows another embodiment of the present invention, wherein the case 1 comprises multiple boxes 12 which are overlapped with each other. Each box 12 has a space 11 defined therein. The space 11 of each of the boxes 12 has the water passage unit 2 and the multiple water turbines 3 received therein. The electric power generators 5 connected to the water turbines 3 are located outside of each of the boxes 12. The first and second passages 21, 22 are inclined toward different directions. Each box 12 has a first opening 121 and a second opening 122, the first opening 121 is located corresponding to the high end of the water passage unit 2, and the second opening 122 is located corresponding to the low end of the water passage unit 2. A pump 7 is located in the space 11 of the case 1 that is located at the lowest position of the overlapped boxes 12 in the case 1. The lowest box 12 has an open area in the top thereof. When in use, the water enters into the top box 12 via the first opening 121 of the top box 12, and the water flows downward along the water passage 2 unit 2 and out from the second opening 122. The water then flows into the second box 12 via the first opening 121 of the second box 12. The water flows through the multiple overlapped boxes 12 and drives the water turbines 3 to generate electric power. It is noted that number of the box 12 can be increased or decreased according to practical needs.

While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention. The present invention can also omit the arrangement of the space 11 or the arrangement of the pump 7, and the water passage units 2 can be arranged in the middlestream or downstream of a river or a spring to lead nature water into the water passage units 2. It can also achieve the purpose of driving the water turbines 3 assembled at the water passages 2 to rotate to drive the electric power generator 5 to generate electric power, and the electric power can be transported to the electric power storage unit 6 to be stored for industrial or livelihood use.
