The disclosure can be more fully understood by reading the following detailed description of the embodiment, with reference made to the accompanying drawings as follows:
Embodiments of the present disclosure are described in detail as follows. However, it can be understood that, the embodiments are provided many applicable concepts, which may implement in any kind of specific context. The embodiments which are described and disclosed in this context are merely provided for illustration and not intended to limit the scope of the present disclosure.
Terms used in this context are merely for distinguishing specific embodiments and not intended to limit the patent scope. Unless otherwise limited, the term “a” or “the” in a singular form may also be used to represent in a plural form.

The rotary shaft 221 includes a core 227 and a rod 228. The core 227 may be, but is not limited to, in a cylinder shape, and the rod 228 is firmly engaged to the core 227. The blades 222 are pivotally connected to the rotary shaft 221 by the pivotal members 223. As shown in
The blades 222 may be expanded or closed relative to the rotary shaft 221. In some embodiments, gaps may be present between the connecting sides 231 of the blades 222 and the rotary shaft 221, and the cover sheets 224 are respectively disposed across the gaps between the connecting sides 231 of the blades 222 and the rotary shaft 221 for blocking fluid to flow therethrough when the turbine 220A is driven. The cover sheets 224 may be made of soft and impermeable material, such as soft plastic material or the like. The stoppers 225 respectively correspond to the blades 222 and are disposed over the rotary shaft 221, and respectively face the convex surfaces 230 of the corresponding blades 222 for limiting the expansion angles of the blades 222. Each elastic member 226 includes a fixed end and a moving end opposite to the fixed end. The fixed ends of the elastic members 226 attach to the rotary shaft 221, and the moving ends of the elastic members 226 respectively attach to the blades 222. The elastic members 226 respectively provide restoration forces for the blades 222 to open (e.g., shown in
Each blade 222 pivots relative to the rotary shaft 221 between an expanded position and a closed position. When each blade 222 is in the expanded position, the active side 232 of each blade 222 is away from the rotary shaft 221, a distance L between the active side 232 of each blade 222 and the center of the rod 228 is the farthest, and the connecting side 231 of each blade 222 is against the corresponding stopper 225 (the convex surface 230 of each blade 222 is against the corresponding stopper 225). In this example, the angle θ between the connecting side 231 of each blade 222 and the tangent of the rotary shaft 221 corresponding thereto is approximately 90 degrees. The blades 222 have the longest lever arms (i.e. the distance L) for reaching the maximum torque when the turbine 220A is in the expanded status.
It should be noted that the elastic members 226 corresponding to the blades 222 are also deformed (e.g. stretched) when the blades 222 are in the expanded positions, but the degree of deformations of the elastic members 226 when the blades 222 are in the expanded positions is less than the degree of deformations of the elastic members 226 when the blades 222 are in the closed positions. Accordingly, the blades 222 do not rotate toward a direction of the closed positions and sustain in the expanded positions without external force because the blades 222 are against the stoppers 225 when the blades 222 do not affect by the external force from a spacing wall 241 (see
Reference is made to
In some embodiments, inner surfaces 248 of the diversion walls 242 respectively facing the channel spaces 243 are curved surfaces, and extend toward interior of the channel spaces 243 in a direction from the sub-inlets 247 to the sub-inlets 246, so that the diverted fluids entering the channel spaces 243 from the sub-inlets 247 form the tangential fluids more easily.
The turbines 220A, 220B and 220C reduce obstacles by the expanded blades 222 or the closed blades 222 when rotating, and eliminate negative power of rotation, so that the turbines 220A, 220B and 220C increase efficiency of converting fluid kinetic energy into mechanical energy.
It should be further noted that each diversion wall 242 may be disposed near one of the adjacent two of the spacing walls 241 which is different from the one of the adjacent two of the spacing walls 241 which is near the accommodated turbine 220A, 220B or 220C, so that the sub-inlet 247 is wider than the sub-inlet 246. The amount of the diverted fluid entering the sub-inlet 247 is more than the amount of the diverted fluid entering the sub-inlet 246, so the diverted fluid entering the sub-inlet 247 may form the stronger tangential fluid so that the blades 222 of the turbine 220A, 220B or 220C are expanded more quickly. The positions disposed by the diversion walls 242 may be adjusted to match the positions where the blades 222 of the corresponding turbines 220A, 220B and 220C need to be expanded. In addition, the flows of the diverted fluids may be adjusted according to adjusting distances between each diversion wall 242 and the corresponding spacing walls 241. For example, when the diversion wall 242 is near one of the spacing walls 241, the space defined by the diversion wall 242 and the spacing wall 241 which is near the diversion wall 242 is smaller, and thus the flow amount of the diverted fluid entering the space is smaller; on the contrary, when the diversion wall 242 is far away from one of the spacing walls 241, the space defined by the diversion wall 242 and the spacing wall 241 which is far away from the diversion wall 242 is large, and thus the flow amount of the diverted fluid entering the space is larger.
In some embodiments, each turbine 220A, 220B or 220C further includes anti-friction members 233, in which the anti-friction members 233 are disposed on the convex surfaces 230 of the blades 222. These anti-friction members 233 are helpful for reducing the friction force exerted by the blades 222 on the spacing walls 241. The anti-friction members 233 may be, for example, rollers and/or smooth coatings.
In some embodiments, the channel structure group 240 further includes anti-friction members (not shown) disposed respectively on contact surfaces of the spacing walls 241. These anti-friction members are helpful for reducing the friction force exerted by the spacing walls 241 on the blades 222. Each anti-friction member may be, for example, a row of rollers and/or a smooth coating.
Each one-way transmission mechanism 300 includes a one-way transmission wheel 310 and a transmission member 320. The one-way transmission wheel 310 is disposed on the rod 228 of one of the turbines 220A, 220B and 220C. The one-way transmission wheel 310 is configured to rotate by a unidirectional direction to transmit power, such as a ratcheting freewheel mechanism, a combination of a one-way bearing and a gear, a combination of a one-way bearing and a pulley, or the like, in which the combination method of the one-way bearing and the gear is that the one-way bearing is disposed at the center of the gear, and the combination method of the one-way bearing and the pulley is that the one-way bearing is disposed at the center of the pulley. The transmission member 320 is disposed between the rod 228 of another turbine 220A, 220B or 220C and the one-way transmission wheel 310. The transmission members 320 transmit power generated by the turbines 220A and 220C to the corresponding one-way transmission wheels 310, and the one-way transmission wheels 310 transmit power generated by the turbines 220A and 220C to the rod 228 of the turbines 220A. The transmission members 320 and the corresponding one-way transmission wheels 310 incorporate together. For example, as shown in
When the rotation speed of the turbines 220A and 220C is higher than or equal to the rotation speed of the turbine 220B for following the rotation of the turbine 220B, the turbines 220A and 220C may transmit power via the one-way transmission mechanisms 300, so that the turbines 220A and 220C share the force that drives the turbine 220B to rotate, such that the turbine 220B rotates more easily. Therefore, the configurations of the one-way transmission mechanisms 300 can be adjusted appropriately according to different components of the force generated by the fluid to the turbines 220A, 220B and 220C.
It should be mentioned that the one-way transmission mechanisms 300 may be used for power devices other than the turbines 220A, 220B and 220C. In some embodiments, the one-way transmission mechanisms 300 are disposed on rotation shafts of power devices (e.g., another type of waterwheels).

In addition, the power devices may share the momentum of the fluid at the same time to reduce damages of the power devices. In some embodiments, the power integrated system may be integrated with other fluid power generating system(s) (e.g., a wind power generating system) to generate power by integrating wind turbines.
