DETAILED DESCRIPTION

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.

Reference is made toFIGS.1A and1B.FIG.1Ais a perspective view of a power generating system100in accordance with some embodiments of the present disclosure, andFIG.1Bis a schematic side view of the power generating system100inFIG.1A. The power generating system100may be a hydropower generating system (as shown inFIG.1A) or another suitable system for generating power. The power generating system100includes a power apparatus200, one-way transmission mechanisms300and a power generator400. The power apparatus200includes turbines220A,220B and220C and a channel structure group240. Other number of turbines (e.g., 1, 2, or more) may be arranged in the power apparatus200in accordance with other embodiments.

FIGS.2and3are respectively a perspective view and a top view of the turbine220A in an expanded status. The structures of the turbines220A,220B and220C are substantially the same. The turbine220A includes a rotary shaft221, blades222, pivotal members223, cover sheets224, stoppers225and elastic members226.

The rotary shaft221includes a core227and a rod228. The core227may be, but is not limited to, in a cylinder shape, and the rod228is firmly engaged to the core227. The blades222are pivotally connected to the rotary shaft221by the pivotal members223. As shown inFIG.2, each blade222may be a curved rectangle plate of which the length may be substantially equivalent to the length of the core227. Each blade222includes a concave surface229and a convex surface230opposite to the concave surface229. In some embodiments, the radius of the curvature of each blade222may be approximately equivalent to the radius of the core227. Further, each blade222includes a connecting side231and an active side232opposite to the connecting side231. Each pivotal member223is disposed between the connecting side231of one of the blades222and the rotary shaft221so that the blades222are disposed on the rotary shaft221at intervals by a predetermined distance in a circumferential direction of the rotary shaft221, and pivot relative to the rotary shaft221. The pivotal members223may be hinges and/or other members suitable for pivotally connecting the blades222to the core227.

The blades222may be expanded or closed relative to the rotary shaft221. In some embodiments, gaps may be present between the connecting sides231of the blades222and the rotary shaft221, and the cover sheets224are respectively disposed across the gaps between the connecting sides231of the blades222and the rotary shaft221for blocking fluid to flow therethrough when the turbine220A is driven. The cover sheets224may be made of soft and impermeable material, such as soft plastic material or the like. The stoppers225respectively correspond to the blades222and are disposed over the rotary shaft221, and respectively face the convex surfaces230of the corresponding blades222for limiting the expansion angles of the blades222. Each elastic member226includes a fixed end and a moving end opposite to the fixed end. The fixed ends of the elastic members226attach to the rotary shaft221, and the moving ends of the elastic members226respectively attach to the blades222. The elastic members226respectively provide restoration forces for the blades222to open (e.g., shown inFIGS.2and3) when the blades222are closed (e.g., shown inFIGS.4and5). The elastic members226may be, for example, rubber bands and/or springs.

Each blade222pivots relative to the rotary shaft221between an expanded position and a closed position. When each blade222is in the expanded position, the active side232of each blade222is away from the rotary shaft221, a distance L between the active side232of each blade222and the center of the rod228is the farthest, and the connecting side231of each blade222is against the corresponding stopper225(the convex surface230of each blade222is against the corresponding stopper225). In this example, the angle θ between the connecting side231of each blade222and the tangent of the rotary shaft221corresponding thereto is approximately 90 degrees. The blades222have the longest lever arms (i.e. the distance L) for reaching the maximum torque when the turbine220A is in the expanded status.

FIGS.4and5are respectively a perspective view and a top view of the turbine220A in a closed status. When each blade222is in the closed position, the active side232of each blade222is adjacent to the rotary shaft221(the concave surface229of each blade222is adjacent to the rotary shaft221), and the angle θ between the connecting side231of each blade222and the tangent of the rotary shaft221corresponding thereto is approximately 0. The connecting side231of each blade222is not against the corresponding stopper225, and meanwhile, the elastic members226are deformed (e.g. stretched) and provide restoration forces to open the blades222.

It should be noted that the elastic members226corresponding to the blades222are also deformed (e.g. stretched) when the blades222are in the expanded positions, but the degree of deformations of the elastic members226when the blades222are in the expanded positions is less than the degree of deformations of the elastic members226when the blades222are in the closed positions. Accordingly, the blades222do not rotate toward a direction of the closed positions and sustain in the expanded positions without external force because the blades222are against the stoppers225when the blades222do not affect by the external force from a spacing wall241(seeFIG.6).

FIG.6exemplarily illustrates fluid flowing to the power apparatus200. As shown inFIGS.1A,1B and6, the channel structure group240includes spacing walls241and diversion walls242. Other number of diversion walls (e.g., 1, 2, or more) may be arranged in the channel structure group240in accordance with other embodiments. The spacing walls241are arranged at intervals along the direction X. Any two adjacent ones of the spacing walls241define a channel space243which is opening, and form an inlet244and an outlet245communicating with each other through the channel space243. Each channel space243is provided for accommodating the turbine220A,220B or220C, and the accommodated turbine220A,220B or220C is adjacent to one of the spacing walls241. The spacing wall241is curved along a rotational direction of the accommodated turbines220A,220B and220C so that the fluid flowing into the channel spaces243are guided by the spacing walls241to drive more blades222of the accommodated turbines220A,220B and220C. Each diversion wall242is disposed between any adjacent two of the spacing walls241to occupy a portion of the inlet244, and divides the inlet244into two sub-inlets246and247for diverting fluid.

Reference is made toFIGS.2and4together. The fluid is diverted into two diverted fluids by each diversion wall242, in which the diverted fluid entering the channel space243from the sub-inlet246may drive the turbine220A,220B or220C to rotate, and a part of the diverted fluid entering the channel space243from the sub-inlet247can flow toward a direction near the sub-inlet246to form tangential fluid to the turbine220A,220B or220C. When the fluid flows into the channel spaces243from the sub-inlets246and247, the turbines220A,220B and220C are driven to rotate by the fluid (in this example, the rotational direction is clockwise), and the blades222of the turbines220A,220B and220C touch the adjacent spacing walls241and move to the closed positions to close near the rotary shafts221through the effects of reaction forces of the spacing walls241. When the closed blades222are near the corresponding diversion walls242, the closed blades222are expanded again through supports of the tangential fluids formed by flowing the corresponding diversion walls242and the effects of the resilience of the corresponding elastic members226. The blades222which are not completely expanded to the expanded positions may be smoothly expanded by the corresponding diversion walls242blocking the fluid flowing directly toward the convex surfaces230.

In some embodiments, inner surfaces248of the diversion walls242respectively facing the channel spaces243are curved surfaces, and extend toward interior of the channel spaces243in a direction from the sub-inlets247to the sub-inlets246, so that the diverted fluids entering the channel spaces243from the sub-inlets247form the tangential fluids more easily.

The turbines220A,220B and220C reduce obstacles by the expanded blades222or the closed blades222when rotating, and eliminate negative power of rotation, so that the turbines220A,220B and220C increase efficiency of converting fluid kinetic energy into mechanical energy.

It should be further noted that each diversion wall242may be disposed near one of the adjacent two of the spacing walls241which is different from the one of the adjacent two of the spacing walls241which is near the accommodated turbine220A,220B or220C, so that the sub-inlet247is wider than the sub-inlet246. The amount of the diverted fluid entering the sub-inlet247is more than the amount of the diverted fluid entering the sub-inlet246, so the diverted fluid entering the sub-inlet247may form the stronger tangential fluid so that the blades222of the turbine220A,220B or220C are expanded more quickly. The positions disposed by the diversion walls242may be adjusted to match the positions where the blades222of the corresponding turbines220A,220B and220C need to be expanded. In addition, the flows of the diverted fluids may be adjusted according to adjusting distances between each diversion wall242and the corresponding spacing walls241. For example, when the diversion wall242is near one of the spacing walls241, the space defined by the diversion wall242and the spacing wall241which is near the diversion wall242is smaller, and thus the flow amount of the diverted fluid entering the space is smaller; on the contrary, when the diversion wall242is far away from one of the spacing walls241, the space defined by the diversion wall242and the spacing wall241which is far away from the diversion wall242is large, and thus the flow amount of the diverted fluid entering the space is larger.

In some embodiments, each turbine220A,220B or220C further includes anti-friction members233, in which the anti-friction members233are disposed on the convex surfaces230of the blades222. These anti-friction members233are helpful for reducing the friction force exerted by the blades222on the spacing walls241. The anti-friction members233may be, for example, rollers and/or smooth coatings.

In some embodiments, the channel structure group240further includes anti-friction members (not shown) disposed respectively on contact surfaces of the spacing walls241. These anti-friction members are helpful for reducing the friction force exerted by the spacing walls241on the blades222. Each anti-friction member may be, for example, a row of rollers and/or a smooth coating.

Each one-way transmission mechanism300includes a one-way transmission wheel310and a transmission member320. The one-way transmission wheel310is disposed on the rod228of one of the turbines220A,220B and220C. The one-way transmission wheel310is 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 member320is disposed between the rod228of another turbine220A,220B or220C and the one-way transmission wheel310. The transmission members320transmit power generated by the turbines220A and220C to the corresponding one-way transmission wheels310, and the one-way transmission wheels310transmit power generated by the turbines220A and220C to the rod228of the turbines220A. The transmission members320and the corresponding one-way transmission wheels310incorporate together. For example, as shown inFIG.1A, the transmission member320may include an assembly of a gear321and a chain322. Alternatively, the transmission member320may include an assembly of a pulley and a belt, or a gear assembly, in which the gear assembly is an assembly of gears and two adjacent ones of the gears are engaged. When the one-way transmission wheel310is the ratcheting freewheel mechanism or the combination of the one-way bearing and the gear, the transmission member320is the assembly of the gear321and the chain322, or the gear assembly. When the one-way transmission wheel310is the combination of the one-way bearing and the pulley, the transmission member320is the assembly of the pulley and the belt. The one-way transmission mechanism300is configured to transmit the power to the one-way transmission wheel310via the transmission member320when the rod228where the transmission member320is disposed rotates in a rotational direction, so that the rod228where the one-way transmission wheel310is disposed rotates in the same rotational direction. In the example illustrated inFIG.1A, two one-way transmission mechanisms300are arranged. One of the one-way transmission mechanisms300is disposed on the turbines220A and220B, and the one-way transmission wheel310of which is disposed on the turbine220B. The other one-way transmission mechanism300is disposed on the turbines220B and220C, and the one-way transmission wheel310of which is disposed on the turbine220B. The rod228of the turbine220B is interlocked with a shaft410of the power generator400. The turbine220B rotating in a rotational direction generates and transmits power directly to the power generator400. When the rods228of the turbines220A and220C rotate in the same rotational direction, the turbines220A and220C generate and transmit power to the power generator400in parallel via the one-way transmission mechanisms300and the shaft410. In particular, for the configuration shown inFIGS.1A and1B, the turbine220A transmits power to the turbine220B via the one-way transmission mechanism300between the turbines220A and220B, and the turbine220C transmits power to the turbine220B via the one-way transmission mechanism300between the turbines220B and220C, and the turbine220B integrates and transmits power to the power generator via the rod228thereof and the shaft410of the power generator400.

When the rotation speed of the turbines220A and220C is higher than or equal to the rotation speed of the turbine220B for following the rotation of the turbine220B, the turbines220A and220C may transmit power via the one-way transmission mechanisms300, so that the turbines220A and220C share the force that drives the turbine220B to rotate, such that the turbine220B rotates more easily. Therefore, the configurations of the one-way transmission mechanisms300can be adjusted appropriately according to different components of the force generated by the fluid to the turbines220A,220B and220C.

It should be mentioned that the one-way transmission mechanisms300may be used for power devices other than the turbines220A,220B and220C. In some embodiments, the one-way transmission mechanisms300are disposed on rotation shafts of power devices (e.g., another type of waterwheels).

FIG.7is a schematic side view of a power integration system of a power generating system700for integrating power in parallel in accordance with some embodiments of the present disclosure. In this example, four power devices710A,710B,710C and710D and three one-way transmission mechanisms720are configured. Rotary shafts711of the power devices710A,710B,710C and710D are driven to rotate for generating power. The power devices710A,710B,710C and710D may be turbines, waterwheels, wind power devices, or the like, in which rotary shafts of the wind power devices are driven by wind for generating power. The one-way transmission mechanisms720are similar to the one-way transmission mechanisms300in structure, and thus the descriptions thereof are not repeated herein.

In the power generating system700shown inFIG.7, one of the one-way transmission mechanisms720is disposed on the power devices710A and710B, and a one-way transmission wheel721of which is disposed on the power device710B. Another one-way transmission mechanism720is disposed on the power devices710B and710C, and a one-way transmission wheel721of which is disposed on the power device710B. The other one-way transmission mechanism720is disposed on the power devices710B and710D, and a one-way transmission wheel721of which is disposed on the power device710B. The rotary shaft711of the power device710B is interlocked with a shaft of a power generator (not shown). The power device710B rotating in a rotational direction generates and transmits power directly to the power generator. When the rotary shafts711of the power devices710A,710C and710D rotate in the same rotational direction, the power devices710A,710C and710D generate and transmit power to the power generator in parallel via the one-way transmission mechanisms720and the shaft of the power generator.

FIG.8is a schematic side view of a power integration system of a power generating system800for integrating power in series in accordance with some embodiments of the present disclosure. In this example, four power devices810A,810B,810C and810D and three one-way transmission mechanisms820are configured. In other embodiment, two power devices and one one-way transmission mechanism are configured. Rotary shafts811of the power devices810A,810B,810C and810D are driven to rotate for generating power. The power devices810A,810B,810C and810D may be turbines, waterwheels, wind power devices, or the like, in which rotary shafts of the wind power devices are driven by wind for generating power. The one-way transmission mechanisms820are similar to the one-way transmission mechanisms300in structure, and thus the descriptions thereof are not repeated herein.

In the power generating system800shown inFIG.8, one of the one-way transmission mechanisms820is disposed on the power devices810A and810B, and a one-way transmission wheel821of which is disposed on the power device810A. Another one-way transmission mechanism820is disposed on the power devices810B and810C, and a one-way transmission wheel821of which is disposed on the power device810B. The other one-way transmission mechanism820is disposed on the power devices810C and810D, and a one-way transmission wheel821of which is disposed on the power device810C. The rotary shaft811of any of the power devices810A,810B and810C is interlocked with a shaft of a power generator (not shown). It is described for this example that the rotary shaft811of the power device810A is interlocked with the shaft of the power generator. The power device810A rotating in a rotational direction generates and transmits power directly to the power generator. When the rotary shafts811of the power devices810B,810C and810D rotate in the same rotational direction, the power devices810B,810C and810D generate and transmit power to the power generator via the one-way transmission mechanisms820and the shaft of the power generator. In particular, for the configuration shown inFIG.8, the power device810D transmits power to the power device810C via the one-way transmission mechanism820between the power devices810C and810D, and then the power device810C integrate and transmit power to the power device810B via the one-way transmission mechanism820between the power devices810B and810C, and then the power device810B integrates and transmits power to the power device810A via the one-way transmission mechanism820between the power devices810A and810B, and last the power device810A integrates and transmits power to the power generator via the rotary shaft811thereof and the shaft of the power generator. That is, the power generated by the power devices810A,810B,810C and810D is integrated in series in a unidirectional power transmission path from the power device810D to the power device810A and then transmitted to the power generator via the rotary shaft811of the power device810A at an endpoint of the unidirectional power transmission path.

The power devices can be disposed as appropriate positions and the power generated by the power devices can be integrated in series or in parallel via the one-way transmission mechanisms, so that the power devices can be disposed more conveniently and the amounts of the power generators which are required can be saved. 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.

FIG.9is a schematic side view of a power integrated system with a wind power system900that integrates the power in parallel in accordance with some embodiments of the present disclosure. In this example, four wind power devices910A,910B,910C and910D and three one-way transmission mechanisms920are configured. Rotary shafts911of the wind power devices910A,910B,910C and910D are driven by wind to rotate for generating power. The one-way transmission mechanisms920are similar to the one-way transmission mechanisms300in structure, and the arrangement of the one-way transmission mechanisms920inFIG.9are similar to the arrangement of the one-way transmission mechanisms720inFIG.7.

In the power integrated system shown inFIG.9, one of the one-way transmission mechanisms920is disposed on the wind power devices910A and910B, and a one-way transmission wheel921of which is disposed on the wind power device910B. Another one-way transmission mechanism920is disposed on the wind power devices910B and910C, and a one-way transmission wheel921of which is disposed on the wind power device910B. The other one-way transmission mechanism920is disposed on the wind power devices910B and910D, and a one-way transmission wheel921of which is disposed on the wind power device910B. The rotary shaft911of the wind power device910B is interlocked with a shaft of a power generator (not shown). The wind power device910B rotating in a rotational direction generates and transmits power directly to the power generator. When the rotary shafts911of the wind power devices910A,910C and910D rotate in the same rotational direction, the wind power devices910A,910C and910D generate and transmit power to the power generator in parallel via the one-way transmission mechanisms920and the shaft of the power generator.
