Description

Technical Field

[0001] The present invention relates to the technical field of hydropower generation, and in particular to a multifunctional hydropower generation device. Background Art

[0002] Hydropower projects are designed to prevent floods and rationally allocate and utilize water resources. They encompass important functions such as flood control, irrigation, water regulation, power generation, and shipping. Power generation is one of the most crucial aspects of hydropower. my country's Three Gorges Dam, the world's largest hydropower station, supplies electricity to numerous cities in central and southern my country. Beyond its basic power generation function, the extended value of hydropower projects continues to expand with technological innovation, including water resource allocation, kinetic energy recovery, and integrated agriculture and fishery production. Existing hydropower generation devices typically rely solely on the rotation of the rotor to generate electricity, failing to achieve other functions. They also lack the ability to release excess water flow, which can damage the device. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention adopts the following technical solutions: a multifunctional hydroelectric power generation device, comprising a power generation mechanism for generating electricity, the power generation mechanism comprising a dam, the power generation mechanism being provided with a sediment mechanism for isolating and measuring sediment, and a flow mechanism for regulating water flow;

[0004] The power generation mechanism comprises four water inlet pipes fixedly mounted on the dam, and power generation fan blades are rotatably mounted in the water inlet pipes.

[0005] Furthermore, the power generation mechanism also includes a power generation shell fixedly mounted on the water inlet pipe, a stator fixedly mounted in the power generation shell, a magnetic pole fixedly mounted on the stator, a rotor fixedly mounted on the power generation blades, and a coil fixedly mounted on the rotor.

[0006] Furthermore, a heating pipe is rotatably installed in the rotor, and the heating pipe is used to dissipate the heat generated by the rotation of the rotor.

[0007] Water flows in from the upper end of the water inlet pipe, and then flows through the generator blades, driving the generator blades, rotor and coil to rotate, thereby generating electricity through the relative movement of the coil and the magnetic pole. At the same time, the heat energy generated by the rotation of the rotor is transmitted out through the heating tube.

[0008] Furthermore, the sediment mechanism includes an upper filter plate and a lower filter plate fixedly installed at the lower end of the water inlet pipe, a downward pressure slope block is slidably installed in the water inlet pipe, a downward pressure spring is arranged between the downward pressure slope block and the water inlet pipe, a sand collecting pool is arranged below the water inlet pipe, and a slope surface is arranged on the downward pressure slope block.

[0009] Furthermore, a rotating impeller is rotatably installed in the water inlet pipe, an impeller gear is fixedly installed on the rotating impeller, an upper gear is rotatably installed on the water inlet pipe, a toothless gear is fixedly installed on the upper gear, and a transmission belt is wrapped around the upper gear and the impeller gear.

[0010] Furthermore, four metering modules are provided on the water inlet pipe, and the metering module includes a counting wheel rotatably mounted on the water inlet pipe, an inner toothed gear and an inner gear ring are fixedly mounted on the counting wheel, three outer gears are rotatably mounted on the water inlet pipe, an inner gear is fixedly mounted on the outer gear, the inner gear is meshed with the inner gear ring, and a scale is provided on the counting wheel.

[0011] Furthermore, the outer gear of the metering module located next to the toothless gear is meshed with the toothless gear, and the outer gears of the remaining three metering modules are meshed with the inner toothless gears of the adjacent metering modules.

[0012] When water flows into the water inlet pipe, the water flow drives the rotating impeller and impeller gear to rotate, and drives the upper gear and the toothless gear to rotate through the transmission belt. The toothless gear drives the outer gear meshing with the toothless gear to rotate intermittently, thereby driving the inner gear to rotate intermittently, thereby driving the inner gear ring and counting wheel of the metering module close to the toothless gear to rotate intermittently, and the outer gear and inner gear of the next metering module are driven to rotate intermittently through the inner toothless gear, thereby driving the inner gear ring and counting wheel of the next metering module to rotate intermittently, and finally driving the four counting wheels to rotate. The farther the counting wheel is from the upper gear, the lower the rotation frequency, and the closer the counting wheel is to the upper gear, the higher the rotation frequency. The water flow is recorded by the rotation of the four counting wheels.

[0013] The upper filter plate and the lower filter plate can allow water to pass through and block the sediment. The blocked sediment will be retained and accumulated on the downward pressure slope block. As the sediment accumulates, the downward pressure slope block gradually descends along the water inlet pipe, the downward pressure spring is compressed, and finally the sediment is discharged into the sediment collecting pool. The sediment content can be calculated according to the scale of the counting wheel and the amount of sediment in the sediment collecting pool.

[0014] Furthermore, the flow mechanism includes a runner fixedly mounted on the power generation fan blades, a number of centrifugal rods are slidably mounted on the runner, an inner spring is arranged between the centrifugal rods and the runner, a lifting rod is slidably mounted on the dam, an upper rack is fixedly mounted on the lifting rod, a gate plate is slidably mounted on the dam, a lower rack is fixedly mounted on the gate plate, and when the upper rack rises, the lower rack is driven to rise through gear transmission.

[0015] Furthermore, a drainage channel is provided in the dam, a drain outlet is provided on the dam, the drainage channel is connected to the drain outlet, the drain outlet is connected to an external drainage pipe, a water inlet is provided on the dam, the water inlet is connected to the drainage channel, a number of pop-up plates are rotatably installed on the dam, a torsion spring is provided between the pop-up plate and the dam, when the gate plate is not raised, the gate plate is located outside the pop-up plate, the torsion spring is in a torsion state, and the water inlet is blocked by the gate plate.

[0016] When the generator blades rotate, they will drive the runner to rotate, thereby driving the centrifugal rod to move outward relative to the runner under the action of centrifugal force, the inner spring is stretched, and the lifting rod and the upper rack are lifted up by the centrifugal rod. The faster the generator blades rotate, the more the lifting rod and the upper rack rise. The upper rack drives the lower rack and the gate plate to rise through a multi-stage gear transmission. The rising gate plate will block the water inlet pipe, thereby adjusting the flow of water entering the water inlet pipe according to the rotation speed of the generator blades. When the gate plate rises to the highest point, it will completely close the upper end of the water inlet pipe, and at this time the gate plate leaves the outside of the pop-up plate, and the torsion spring rebounds, causing the pop-up plate to pop out to the lower end of the gate plate and support the gate plate. Since the pop-up plate can no longer rotate relative to the dam, the gate plate cannot fall. At this time, the generator blades stop rotating and the gate plate will not fall. Manual reset of the gate plate is required to ensure the safety of the equipment. At this time, water flows from the water inlet into the drain and is finally discharged from the drain outlet for discharge.

[0017] Compared with the prior art, the present invention has the following advantages: (1) the power generation mechanism provided in the present invention can generate electricity under the action of water flow and can utilize the heat energy generated in the power generation process; (2) the sediment mechanism provided in the present invention can isolate sediment and measure the sediment content in the water, which is convenient for analyzing the water quality; (3) the flow mechanism provided in the present invention can adjust the water flow of the water inlet pipe according to the size of the water flow, and when the water flow is too large, the water inlet pipe will be closed to protect the power generation mechanism and discharge the water.

DETAILED DESCRIPTION

[0035] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0036] Example: Reference Figures 1-16 A multifunctional hydroelectric power generation device includes a power generation mechanism for generating electricity, the power generation mechanism includes a dam 101, and the power generation mechanism is provided with a sediment mechanism for isolating and measuring sediment and a flow mechanism for regulating water flow;

[0037] The power generation mechanism includes four water inlet pipes 102 fixedly mounted on the dam 101 , and power generation blades 104 are rotatably mounted in the water inlet pipes 102 .

[0038] like Figure 2-Figure 5 As shown, the power generation mechanism also includes a power generation shell 103 fixedly mounted on the water inlet pipe 102, a stator 105 fixedly mounted in the power generation shell 103, a magnetic pole 106 fixedly mounted on the stator 105, a rotor 107 fixedly mounted on the power generation blades 104, and a coil 108 fixedly mounted on the rotor 107.

[0039] like Figure 2-Figure 5 As shown, a heating pipe 109 is rotatably installed in the rotor 107 , and the heating pipe 109 is used to dissipate heat generated by the rotation of the rotor 107 .

[0040] Water flows in from the upper end of the water inlet pipe 102, and then flows through the power generation fan blades 104, driving the power generation fan blades 104, the rotor 107 and the coil 108 to rotate, thereby generating electricity through the relative movement of the coil 108 and the magnetic pole 106. At the same time, the heat energy generated by the rotation of the rotor 107 is transmitted through the heating tube 109.

[0041] like Figures 6-10As shown, the sediment mechanism includes an upper filter plate 201 and a lower filter plate 202 fixedly installed at the lower end of the water inlet pipe 102, a downward pressure slope block 203 is slidably installed in the water inlet pipe 102, a downward pressure spring 204 is arranged between the downward pressure slope block 203 and the water inlet pipe 102, a sand collecting pool 205 is arranged below the water inlet pipe 102, and a slope is arranged on the downward pressure slope block 203.

[0042] like Figures 6-10 As shown, a rotating impeller 206 is rotatably installed in the water inlet pipe 102, an impeller gear 207 is fixedly installed on the rotating impeller 206, an upper gear 210 is rotatably installed on the water inlet pipe 102, a toothless gear 211 is fixedly installed on the upper gear 210, and a transmission belt 208 is wrapped around the upper gear 210 and the impeller gear 207.

[0043] like Figures 6-10 As shown, four metering modules are provided on the water inlet pipe 102, and the metering module includes a counting wheel 209 rotatably mounted on the water inlet pipe 102, an inner toothed gear 213 and an inner gear ring 212 are fixedly mounted on the counting wheel 209, three outer gears 214 are rotatably mounted on the water inlet pipe 102, an inner gear 215 is fixedly mounted on the outer gear 214, and the inner gear 215 is meshed with the inner gear ring 212, and a scale is provided on the counting wheel 209.

[0044] like Figures 6-10 As shown, the outer gear 214 of the metering module located next to the toothless gear 211 is engaged with the toothless gear 211 , and the outer gears 214 of the remaining three metering modules are engaged with the inner toothless gears 213 of the adjacent metering modules.

[0045] When water flows into the water inlet pipe 102, the water flow drives the rotating impeller 206 and the impeller gear 207 to rotate, and drives the upper gear 210 and the toothless gear 211 to rotate through the transmission belt 208. The toothless gear 211 drives the outer gear 214 meshing with the toothless gear 211 to rotate intermittently, thereby driving the inner gear 215 to rotate intermittently, thereby driving the inner gear ring 212 and the counting wheel 209 of the metering module close to the toothless gear 211 to rotate intermittently, and drives the outer gear 214 and the inner gear 215 of the next metering module to rotate intermittently through the inner toothless gear 213, thereby driving the inner gear ring 212 and the counting wheel 209 of the next metering module to rotate intermittently, and finally drives the four counting wheels 209 to rotate. The farther the counting wheel 209 is from the upper gear 210, the lower the rotation frequency, and the closer the counting wheel 209 is to the upper gear 210, the higher the rotation frequency. The water flow is recorded by the rotation of the four counting wheels 209.

[0046] The upper filter plate 201 and the lower filter plate 202 can allow water to pass through and block the silt. The blocked silt will be retained and accumulated on the downward pressure slope block 203. As the silt accumulates, the downward pressure slope block 203 gradually descends along the water inlet pipe 102, and the downward pressure spring 204 is compressed, and finally the silt is discharged into the silt collecting pool 205. The silt content can be calculated based on the scale of the counting wheel 209 and the amount of silt in the silt collecting pool 205.

[0047] like Figures 11-16 As shown, the flow mechanism includes a runner 303 fixedly mounted on the power generation fan blade 104, a plurality of centrifugal rods 304 are slidably mounted on the runner 303, an inner spring 305 is arranged between the centrifugal rod 304 and the runner 303, a lifting rod 306 is slidably mounted on the dam 101, an upper rack 307 is fixedly mounted on the lifting rod 306, a gate plate 301 is slidably mounted on the dam 101, a lower rack 308 is fixedly mounted on the gate plate 301, and when the upper rack 307 rises, the lower rack 308 is driven to rise through gear transmission.

[0048] like Figures 11-16 As shown, a drainage channel 312 is provided in the dam 101, a drain port 302 is provided on the dam 101, the drainage channel 312 is connected to the drain port 302, the drain port 302 is connected to an external drainage pipe, a water inlet 309 is provided on the dam 101, the water inlet 309 is connected to the drainage channel 312, a plurality of pop-up plates 310 are rotatably installed on the dam 101, a torsion spring 311 is provided between the pop-up plate 310 and the dam 101, when the gate plate 301 is not raised, the gate plate 301 is located outside the pop-up plate 310, the torsion spring 311 is in a torsion state, and the water inlet 309 is blocked by the gate plate 301.

[0049] When the power generation fan blade 104 rotates, it drives the runner 303 to rotate, thereby driving the centrifugal rod 304 to move outward relative to the runner 303 under the action of centrifugal force, and the inner spring 305 is stretched, and the lifting rod 306 and the upper rack 307 are lifted up by the centrifugal rod 304. The faster the speed of the power generation fan blade 104, the more the lifting rod 306 and the upper rack 307 rise. The upper rack 307 drives the lower rack 308 and the gate plate 301 to rise through the multi-stage gear transmission. The rising gate plate 301 will block the water inlet pipe 102, thereby adjusting the flow of water entering the water inlet pipe 102 according to the speed of the power generation fan blade 104. When 01 rises to the highest point, the upper end of the water inlet pipe 102 will be completely closed, and at this time the gate plate 301 leaves the outside of the pop-up plate 310, and the torsion spring 311 rebounds, causing the pop-up plate 310 to pop out and reach the lower end of the gate plate 301, supporting the gate plate 301. Since the pop-up plate 310 can no longer continue to rotate relative to the dam 101, the gate plate 301 cannot descend. At this time, the power generation fan blades 104 stop rotating and the gate plate 301 will not descend. Manual reset of the gate plate 301 is required to ensure the safety of the equipment. At this time, water flows from the water inlet 309 into the drain channel 312, and is finally discharged from the drain port 302 for discharge.

[0050] The working principle of the multifunctional hydroelectric power generation device disclosed in the present invention is as follows: water flows into from the upper end of the water inlet pipe 102, and then the water flows through the power generation fan blades 104, driving the power generation fan blades 104, the rotor 107 and the coil 108 to rotate, thereby generating electricity through the relative movement of the coil 108 and the magnetic pole 106, and at the same time, the heat energy generated by the rotation of the rotor 107 is transmitted through the heating tube 109. When water flows into the water inlet pipe 102, the water flow drives the rotating impeller 206 and the impeller gear 207 to rotate, and drives the upper gear 210 and the toothless gear 211 to rotate through the transmission belt 208. The toothless gear 211 drives the outer gear 214 meshing with the toothless gear 211 to rotate intermittently, thereby driving the inner gear 215 to rotate intermittently, thereby driving the inner gear ring 212 and the counting wheel 209 of the metering module close to the toothless gear 211 to rotate intermittently, and drives the outer gear 214 and the inner gear 215 of the next metering module to rotate intermittently through the inner toothless gear 213, thereby driving the inner gear ring 212 and the counting wheel 209 of the next metering module to rotate intermittently, and finally drives the four counting wheels 209 to rotate. The farther the counting wheel 209 is from the upper gear 210, the lower the rotation frequency, and the closer the counting wheel 209 is to the upper gear 210, the higher the rotation frequency. The water flow is recorded by the rotation of the four counting wheels 209. The upper filter plate 201 and the lower filter plate 202 can allow water to pass through and block the silt. The blocked silt will be retained and accumulated on the downward pressure slope block 203. As the silt accumulates, the downward pressure slope block 203 gradually descends along the water inlet pipe 102, and the downward pressure spring 204 is compressed, and finally the silt is discharged into the silt collecting pool 205. The silt content can be calculated based on the scale of the counting wheel 209 and the amount of silt in the silt collecting pool 205. When the power generation fan blade 104 rotates, it drives the runner 303 to rotate, thereby driving the centrifugal rod 304 to move outward relative to the runner 303 under the action of centrifugal force, and the inner spring 305 is stretched, and the lifting rod 306 and the upper rack 307 are lifted up by the centrifugal rod 304. The faster the speed of the power generation fan blade 104, the more the lifting rod 306 and the upper rack 307 rise. The upper rack 307 drives the lower rack 308 and the gate plate 301 to rise through the multi-stage gear transmission. The rising gate plate 301 will block the water inlet pipe 102, thereby adjusting the flow of water entering the water inlet pipe 102 according to the speed of the power generation fan blade 104. When 01 rises to the highest point, the upper end of the water inlet pipe 102 will be completely closed, and at this time the gate plate 301 leaves the outside of the pop-up plate 310, and the torsion spring 311 rebounds, causing the pop-up plate 310 to pop out and reach the lower end of the gate plate 301, supporting the gate plate 301. Since the pop-up plate 310 can no longer continue to rotate relative to the dam 101, the gate plate 301 cannot descend. At this time, the power generation fan blades 104 stop rotating and the gate plate 301 will not descend. Manual reset of the gate plate 301 is required to ensure the safety of the equipment. At this time, water flows from the water inlet 309 into the drain channel 312, and is finally discharged from the drain port 302 for discharge.

Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and inventive concept of the present invention within the technical scope of the present invention, which should be covered by the scope of protection of the present invention.
