Abstract

A hydroelectric power device comprises a hydroelectric power unit and a floating diversion unit. The floating diversion unit is connected to the hydroelectric power unit and is used to guide the water flow to the hydroelectric power unit. The floating diversion unit divides the water flow into upwelling water flow and sinking water flow. The level of the upwelling water flow is higher than the level of the sinking water flow. The level of the upwelling water flow is higher than the level of the sinking water flow. Compared with the traditional hydroelectric power device, since the upwelling water flow will impact the blades located above the water surface, the blades will be stressed earlier and the power generation efficiency will be enhanced. The height of the sinking water flow is lower than the normal water surface, so that the inclination angle of the blade when entering the water surface is relatively vertical, preventing the blade from hitting the water surface in a large area, and improving the service life. The hydroelectric power device can adjust the draft with the aid of a suspension adjustment unit.

In order to increase the number of effective blades, the blades of the traditional wheel-type power generation device have a deeper draft. As the blade draft is deeper, the inclination angle of the blades entering the water will be larger, and the back of the blade will hit the water surface in a large area, resulting in noise and strong reaction. The strong reverse resistance generated will damage the blades and reduce the service life.

Schematic diagram of the diversion. It should be noted that, FIG. 1B is a simple plan view of FIG. 1A , and simplifies the specific structure in FIG. 1A . In FIG. In order to achieve at least one of the above advantages or other advantages, an embodiment of the present invention provides a hydroelectric power generation device 10, which is a device for generating electricity by means of water power. As shown in the figure, the hydroelectric power generation device 10 includes a hydroelectric power generation unit 100 and a floating diversion unit 200 .

The hydroelectric power generation unit 100 is a power generation device that generates power by the impingement of the water flow W. As shown in FIG. The floating diversion unit 200 is connected to the water turbine power generation unit 100 for guiding the water flow W to the water wheel The power generation unit 100 is used to help improve the power generation of the hydroelectric power generation unit 100 . As shown in FIG. 1B , the entire water channel is divided and defined into a plurality of areas, which are the normal flow area A1, the acceleration area A2, the diversion area A3, the force rotation area A4 of the blade 135, and the diffusion area in sequence along the flow direction of the water flow W. A5.

The normal flow area A1 refers to the area where the water flow W normally flows, and has not yet been affected by the relevant action of the hydroelectric generating unit 100 of the present invention.

The acceleration zone A2 is used to accelerate the flow rate of the water flow W into the hydroelectric generating unit 100 , which can be used to accelerate the flow speed of the water flow W by the arrangement of the first pontoon group 220 and the second pontoon group 230 , so as to increase the force for pushing the blades 135 For the purpose of increasing the power generated by the hydroelectric generating unit 100, for a more detailed description, please refer to the content corresponding to FIG. 4 and FIG. 5 below.

Please refer to FIG. 2 together. In the diversion area A3, the floating diversion unit 200 divides the water flow W flowing through it into a rising water flow U and a sinking water flow S. The level of the rising water flow U is higher than that of the downward flow. The level of the submerged water flow S. The upwelling water flow U guided to a high place will impact the high-placed vanes 135, increasing the number of vanes 135 effectively impacted by water, and making the vanes 135 impacted by water earlier, finally enhancing the impeller thrust and increasing the power generation. The sinking water flow S guided to the lower part will make the inclination angle of the blade 135 more vertical when it enters the water surface, preventing the blade 135 from hitting the water surface in a large area, and improving the service life. That is to say, the water flow surface height of the sinking water flow S is lower than the liquid surface height of the normal water flow W, so that the area where the blade 135 is impacted by the water flow is lower than the liquid level of the normal water flow W, then the blades 135 will contact at a more vertical angle The water flow S sinks to the liquid level to prevent the blades 135 from hitting the water surface in a large area.

The force rotation area A4 of the blades 135 means that the blades 135 are impacted by the water flow W to drive the wheel engine 110 to rotate, thereby causing the generator 170 to generate electricity. Specifically, the blades 135 at the top are rotated by the impact of the upwelling water flow U, and here the blades 135 have no corresponding resistance due to the backside of the blades 135, so the rotation speed is faster, and the power generation is enhanced; the blades 135 at the lower positions are mostly affected by The level of the sinking current S The blade 135 will be in contact with it in a more vertical state due to the lower height of the sinking water flow S, so that the blade 135 will receive a stronger thrust, and the power generation will be enhanced. For a more detailed description, refer to the content corresponding to FIG. 3 below.

The diffusion area A5 is an area for diffusing and releasing the water flow W. As shown in FIG. When the water flow W with the flow velocity transmits energy to the hydro-generating unit 100, the flow velocity of the outflow will become slower. If the width of the inlet and outlet of the water flow is the same, under the same flow conditions of the inlet and outlet (continuity theorem), the outlet water level will rise. high, which causes clogging, reduced water flow, and reduced power. The present invention designs the diffusion region A5 to solve this problem. In one embodiment, in this case, the distance between the tail ends of the first pontoon group 220 and the second pontoon group 230 is greater than the distance between the head ends of the first pontoon group 220 and the second pontoon group 230 , wherein the head end and the tail end are along the It is defined by the flow direction of the water flow W. In other words, the water flow W will first flow into the narrower head end, and then flow out from the wider tail end, so as to avoid the occurrence of blockage and ensure the power generation. However, this case is not limited to this. In other embodiments, as shown in FIG. 1B , the end of the wheel engine 110 of the hydroelectric generating unit 100 can be made to protrude from the first pontoon group 220 and the second pontoon group 230 , so that the water flow area discharged by the wheel engine 110 is more In this way, the outlet area of the water flow is larger than the inlet area of the water flow, which can also solve the above problem. Alternatively, the width of the water flow outlet of the wheel engine 110 is larger than the width of the water flow inlet, which can avoid clogging and increase the power generation efficiency.

The second wheel 150 is connected to the generator 170 . The blade seats 130 are made of water The wheel main shaft 120 is a symmetrical axis and is evenly distributed around the water wheel main shaft 120 . A plurality of blades 135 are evenly arranged in each blade seat 130 . When the water flow hits the blade seat 130 and the blades 135 , the entire wheel engine 110 is rotated, and the wheel engine 110 drives the first wheel 140 to rotate through the water wheel main shaft 120 . The rotation of the chisel wheel 150, and the rotation of the second chisel wheel 150 can cause the generator 170 to generate electricity.

In one embodiment, the water wheel main shaft 120 is located at the circumferential center of the wheel engine 110 to generate electricity uniformly. However, the present case is not limited to this.

The flow unit 200 is connected with the hydroelectric power unit 100 .

The flow-guiding surge plate 210 is disposed between the first buoy group 220 and the second buoy group 230 , and is used for distinguishing the water flow W into the upwelling water flow U and the sinking water flow S.

The deflecting surge plate 210 has a certain inclination angle α, and the inclination angle α ranges from 10 degrees to 60 degrees, including 10 degrees and 60 degrees, so as to ensure that the flow rate of the upwelling water U, the angle of the impingement blade 135 and the strength.

Looking further, the floating diversion unit 200 further includes a first connecting plate 260 , a second connecting plate 270 , three first buoy holders 280 and three second buoy holders 290 . The first pontoon group 220 includes three first pontoons 225 , and the second pontoon group 230 includes a plurality of second pontoons 235 .

The first connecting plate 260 and the second connecting plate 270 are engaged with the hydroelectric generating unit 100 through the hook portions 265 and 275, so as to strengthen the The connection between the hydroelectric power generation unit 100 and the floating diversion unit 200 .

In an embodiment, as shown in FIGS. 1 and 6 , the hydroelectric power generation device 10 further includes a suspension adjustment unit 300 . The suspension adjusting unit 300 is connected to the hydroelectric generating unit 100 for adjusting the draft of the hydroelectric generating unit 100 . The suspension adjustment unit 300 includes a support frame 310 , a hook member 320 and a counterweight adjustment unit 330 . The support frame 310 can be fixed on the ground and plays a role of supporting the whole. The opposite ends of the support frame 310 are respectively connected to the hook member 320 and the counterweight adjustment unit 330 . The hook member 320 is connected to the hydroelectric generating unit 100 to provide pulling force for the hydroelectric generating unit 100 .

The counterweight adjusting unit 330 is used to adjust the draft of the hydroelectric generating unit 100 . The weight adjusting unit 330 includes a spring member 332 and at least one weight 334 .

The arrangement of the spring member 332 can buffer the up-and-down force received by the wheel engine 110 . The number of the counterweight weights 334 can be multiple, and can be changed according to actual counterweight requirements.

The present invention utilizes the buoyancy of the buoy and the design of the counterweight adjustment unit 330 to adjust and maintain the draft of the hydroelectric generator 10 . Specifically, when the water level in the canal changes due to factors such as rainfall, the hydroelectric generator 10 of the present invention can automatically adjust the draft to achieve better power generation efficiency. For example: when the water level is high, the weight of the counterweight adjustment unit 330 can be increased (the weight 334 can be added), the actual buoyancy of the buoy will be reduced, and the draft of the hydroelectric power generation device 10 will be shallow to ensure the power generation efficiency; otherwise, When the water level is low, the weight of the counterweight adjustment unit 330 can be reduced (reduce the weight 334 ), the actual buoyancy of the buoy will increase, and the draft of the hydroelectric power generation device 10 will be deeper to ensure power generation efficiency.

In general, first, the water flow W is free to flow to the floating diversion unit. Next, the water flow W is divided into the upwelling water flow U and the sinking water flow S by the guide upwelling plate 210. During this process, due to the arrangement of the two pontoon groups, a relatively narrow water flow will be formed between the two pontoon groups. The inlet helps to increase the flow rate of the water flow W entering, further enhance the impact force of the water flow W, increase the force of the impeller, and improve the power generation. Subsequently, the upwelling water flow U and the sinking water flow S jointly impact the blade seat 130 and the blades 135 , and push the wheel engine 110 to operate, so that the generator 170 generates electricity. Finally, the water flow W flows out from the water outlet.

It should be added that the hydroelectric power generation unit 100 of the present application may also be a power generation device with other structures, that is, the hydroelectric power generation unit 100 only needs to be a device that generates power by means of water flow thrust. In addition, when disasters such as floods come, the hydroelectric power generation device 10 of the present application can suspend the hydroelectric power generation unit 100 and the floating guide unit 200 by means of the suspension adjustment unit 300 to avoid the hydropower generation unit 100 and the floating guide unit 200 being suspended.

In summary, using the hydroelectric power generation device 10 provided by the present invention, the water flow W is divided into the upwelling water flow U and the sinking water flow S by the floating diversion unit 200, and the upwelling water flow is guided to a high place. U will impact the blades 135 at high places, increasing the number of blades 135 effectively impacted by water, and making the blades 135 impacted by water earlier, enhancing the impeller thrust, and increasing the power generation; The inclination angle of the blade 135 when it enters the water surface can be made more vertical, so that the blade 135 can be prevented from hitting the water surface in a large area, and the service life can be improved. In addition, if there is only a pontoon and no suspended counterweight design, the draft is fixed. In the present invention, the suspending adjustment unit 300 can also adjust and maintain the draft of the hydroelectric generating device 10 as required to achieve the best efficiency.
