[0002] A pumped-storage hydroelectric power station is a type of hydroelectric power station that uses electricity generated during off-peak hours to pump water into an upper reservoir and then releases the water into a lower reservoir to generate electricity during peak hours. The reservoirs of pumped-storage power stations are open-type, and the surface often contains floating debris, garbage, and aquatic plants. Since pumped-storage power stations generate electricity using water from the reservoir, these floating objects, if sucked into the generator, can damage the generator's turbine. Utility Model Content

[0007] A wind-powered rotating structure is located on the filter tank, and the wind-powered rotating structure is connected to the connecting part of the spiral pump rod;

[0008] When the wind-powered rotating structure rotates, the connecting part rotates under the drive of the wind-powered rotating structure, and then the spiral part rotates so that water containing floating objects in the reservoir flows into the pump cylinder through the inlet and flows out of the pump cylinder through the outlet and into the filter tank.

[0009] Furthermore, the wind-powered rotating structure includes a connecting assembly, a wind-powered rotating component, and guide fins. The connecting assembly is rotatably connected to the filter tank, the wind-powered rotating component is rotatably connected to the connecting assembly, and the guide fins are located on the connecting assembly.

[0010] The wind-powered rotating component includes a wind turbine blade assembly and a rotating shaft. One end of the rotating shaft is connected to the center of the wind turbine blade assembly, and the other end is connected to the connecting part of the helical pump rod. The rotating shaft rotates with the wind turbine blade assembly and is arranged parallel to the guide fins.

[0011] Furthermore, the connecting assembly includes a rotating column and a connecting bracket connected in sequence. The rotating column is rotatably connected to the filter tank, the guide fins are fixedly connected to the connecting bracket, and the rotating shaft of the wind turbine rotates passes through the connecting bracket and is rotatably connected to the connecting bracket.

[0012] Furthermore, a fixing plate extends from the bottom of the filter tank, and the rotating column is located on the fixing plate and is rotatably connected to the fixing plate.

[0013] Furthermore, the pump cylinder is connected to the filter tank via the connecting bracket.

[0014] Furthermore, the cleaning device also includes a transmission rod, which is rotatably connected to the connecting assembly. The transmission rod is provided with a first parachute wheel and a first gear. A second parachute wheel is provided at the end of the rotating shaft away from the wind turbine blade assembly. A second gear is provided at the connecting part of the spiral pump rod. The first parachute wheel and the second parachute wheel are meshed together.

In addition, the pumping component includes a pump barrel and a spiral pump rod. The liquid inlet of the pump barrel is located at the water surface, and floating objects on the water surface can enter the pump barrel through the liquid inlet. The connecting part of the spiral pump rod is connected to the wind-powered rotating structure so that the spiral pump rod rotates with the wind-powered rotating structure. The rotation of the spiral part of the spiral pump rod can drive the water and floating objects at its bottom to move, thereby achieving the effect of pumping water. The wind-powered rotating structure of this application rotates under the action of wind, which in turn drives the spiral pump rod of the water pumping component to rotate, thereby achieving the purpose of pumping water and discharging the pumped water containing floating debris into the filter tank.

[0026] As described in the background section, a pumped-storage power station is a hydroelectric power station that uses electricity generated during off-peak hours to pump water into an upper reservoir and releases it into a lower reservoir to generate electricity during peak hours. The reservoir of a pumped-storage power station is open, and the surface often contains floating debris, garbage, or aquatic plants. Since pumped-storage power stations generate electricity using water from the reservoir, these floating objects, if sucked into the generator, can damage the generator's turbine.

[0027] Based on this, this application proposes a pumped storage power station reservoir cleaning device to clean floating objects in the pumped storage power station reservoir, so as to avoid the situation where floating objects enter the generator and cause damage to the generator during the operation of the pumped storage power station.

[0028] The present application will be described in detail below through one or more specific embodiments.

[0029] In some embodiments, a pumped storage power station reservoir cleaning device, such as Figure 1 and Figure 2 As shown, it includes:

[0030] Filter tank 10;

[0031] The pumping component 20 includes a pump barrel 21 and a spiral pump rod 22. The pump barrel 21 is connected to the filter tank 10. The spiral pump rod 22 includes a spiral portion 221 and a connecting portion 222 connected to each other. The spiral portion 221 is located inside the pump barrel 21. The connecting portion 222 protrudes relative to the top of the pump barrel 21. The bottom of the pump barrel 21 away from the filter tank 10 is provided with an inlet 211, and the top of the pump barrel 21 near the filter tank 10 is provided with an outlet 212. The outlet 212 is located above the filter tank 10.

[0032] A wind-powered rotating structure 30 is located on the filter tank 10, and the wind-powered rotating structure 30 is connected to the connecting part 222 of the spiral pump rod 22.

[0033] When the wind-powered rotating structure 30 rotates, the connecting part 222 rotates under the drive of the wind-powered rotating structure 30, and then the spiral part 221 rotates so that water containing floating objects in the reservoir flows into the pump cylinder 21 through the liquid inlet 211 and flows out of the pump cylinder 21 through the liquid outlet 212 and into the filter tank 10.

[0034] Specifically, the pumping component 20 includes a pump cylinder 21 and a spiral pump rod 22. The top and bottom of the pump cylinder 21 are closed structures. The spiral pump rod 22 passes through the top of the pump cylinder 21 so that the spiral part 221 is located inside the pump cylinder 21. The connecting part 222 is located outside the pump cylinder 21 and protrudes relative to the top of the pump cylinder 21 so as to connect with the wind-powered rotating structure 30.

[0035] The wind-powered rotating structure 30 can rotate under the action of wind. The connecting part 222 of the spiral pump rod 22 is connected to the wind-powered rotating structure 30. Correspondingly, the connecting part 222 of the spiral pump rod 22 can rotate with the wind-powered rotating structure 30. Furthermore, the spiral pump rod 22 can rotate with the wind-powered rotating structure 30. When the spiral part 221 of the spiral pump rod 22 rotates, it can drive the water to move, thereby achieving the effect of pumping water.

[0036] Furthermore, the two ends of the spiral portion 221 of the spiral pump rod 22 are located at the inner bottom and inner top of the pump barrel 21, respectively, to ensure the pumping performance of the pumping component 20. The liquid inlet 211 of the pump barrel 21 is located at the side bottom of the pump barrel 21, and the liquid inlet 211 is partially or completely below the horizontal plane so that the spiral portion 221 located inside the pump barrel 21 can contact the water and achieve pumping. The liquid outlet 212 is located at the side top of the pump barrel 21. When the spiral pump rod 22 rotates, it can move the water located at the liquid inlet 211 to the liquid outlet 212 for discharge. The liquid inlet 211 is located on the side of the pump barrel 21 away from the filter tank 10 so that more floating objects exist near the liquid inlet 211, which is beneficial for the cleaning device to clean the floating objects on the water surface.

[0037] The pumping unit 20 pumps water containing floating objects into the filter tank 10 through the outlet 212. The filter tank 10 filters the water containing floating objects, so that the floating objects are located in the filter tank 10, thereby cleaning the floating objects in the reservoir and preventing them from affecting the power generation of the reservoir.

[0038] In this embodiment, by setting up a pumping component 20, a wind-powered rotating structure 30, and a filter tank 10 connected together, the pumping component 20 can pump water under the drive of the wind-powered rotating structure 30 and discharge the pumped water into the filter tank 10 to filter impurities in the water, thereby achieving the effect of cleaning impurities in the reservoir. In addition, the pumping component 20 includes a pump barrel 21 and a spiral pump rod 22. The inlet 211 of the pump barrel 21 is located at the water surface, and floating objects on the water surface can enter the pump barrel 21 through the inlet 211. The connecting part 222 of the spiral pump rod 22 is connected to the wind-powered rotating structure 30 so that the spiral pump rod 22 rotates with the wind-powered rotating structure 30. The rotation of the spiral part 221 of the spiral pump rod 22 can drive the water and floating objects at its bottom to move, thereby achieving the effect of pumping water. The wind-powered rotating structure 30 of this application rotates under the action of wind, thereby driving the spiral pump rod 22 of the pumping component 20 to rotate, achieving the purpose of pumping water, and discharging the pumped water containing floating objects (debris) into the filter tank 10, thereby achieving automatic cleaning of floating objects on the surface of the reservoir. This not only prevents floating objects in the reservoir from entering the generator and causing damage to the generator, but also reduces the cost of cleaning floating objects on the surface of the reservoir. It is highly practical and suitable for widespread application.

[0039] In some embodiments, the wind-powered rotating structure 30 includes a connecting component 31, a wind-powered rotating component 32, and a guide fin 33. The connecting component 31 is rotatably connected to the filter tank 10, the wind-powered rotating component 32 is rotatably connected to the connecting component 31, and the guide fin 33 is located on the connecting component 31.

[0040] The wind-powered rotating component 32 includes a wind turbine blade assembly 321 and a rotating shaft 322. One end of the rotating shaft 322 is connected to the center of the wind turbine blade assembly 321, and the other end is connected to the connecting part 222 of the spiral pump rod 22. The rotating shaft 322 rotates with the wind turbine blade assembly 321, and the rotating shaft 322 is arranged parallel to the guide fins 33.

[0041] Specifically, the connecting assembly 31 is rotatably connected to the filter tank 10 and can rotate relative to the filter tank 10. The wind-powered rotating component 32 is rotatably connected to the connecting assembly 31 through the rotating shaft 322, so that the wind-powered rotating component 32 can be located on the connecting assembly 31 and can rotate relative to the connecting assembly 31. The guide fins 33 are fixedly connected to the connecting assembly 31 and can deflect relative to the filter tank 10 under the action of wind, thereby driving the connecting assembly 31 and the wind-powered rotating component 32 to deflect relative to the filter tank 10.

[0042] The wind-powered rotating component 32 includes a wind turbine blade assembly 321 and a rotating shaft 322. The rotating shaft 322 is fixedly connected to the center of the wind turbine blade assembly 321. The plane of the wind turbine blade assembly 321 is perpendicular to the rotating shaft 322, meaning the wind turbine blade assembly 321 can rotate under wind force, causing the rotating shaft 322 to rotate in the same direction. The length direction of the guide fins 33 is parallel to the rotating shaft 322 of the wind-powered rotating component 32, and correspondingly, the plane of the wind turbine blade assembly 321 is perpendicular to the length direction of the guide fins 33. When subjected to wind force, the guide fins 33 will deflect to a position where the wind force is perpendicular to the plane of the guide fins 33. Correspondingly, the wind turbine blade assembly 321 is deflected to a position perpendicular to the wind direction, allowing the wind force to act on the wind turbine blades with maximum force, causing the wind turbine blade assembly 321 to rotate. Consequently, the rotating shaft 322 rotates. The guide fins 33 facilitate the wind turbine rotating component 32 to rotate with maximum efficiency under the action of wind, thereby enabling the pumping component 20 to pump water with maximum efficiency, achieving the filtration and cleaning of floating debris on the reservoir surface. The wind turbine rotating structure 30 not only improves the cleaning efficiency of the cleaning device but also maximizes the utilization of wind resources, reduces the cost of the cleaning device, and is conducive to sustainable development and widespread application.

[0043] In some embodiments, the connecting assembly 31 includes a rotating column 311 and a connecting bracket 312 connected in sequence. The rotating column 311 is rotatably connected to the filter tank 10, the guide fins 33 are fixedly connected to the connecting bracket 312, and the rotating shaft 322 of the wind turbine rotator 32 passes through the connecting bracket 312 and is rotatably connected to the connecting bracket 312.

[0044] Specifically, one end of the rotating column 311 is rotatably connected to the filter tank 10, and the other end is fixedly connected to the connecting bracket 312. The connecting bracket 312 is used to connect the guide fins 33 and the wind-powered rotating component 32. When the guide fins 33 deflect under the action of wind, they drive the connecting bracket 312 and the rotating shaft to deflect at a corresponding angle relative to the filter tank 10. The wind-powered rotating component 32 also deflects at a corresponding angle under the action of the connecting bracket 312.

[0045] In addition, the guide fins 33 and the rotating shaft 322 are arranged in parallel. To facilitate the installation of the guide fins 33 and the rotating shaft 322, the connecting bracket 312 may include a connecting vertical plate and a connecting horizontal plate. The connecting vertical plate is connected to the rotating shaft, and the guide fins 33 are located on the connecting horizontal plate so that the guide fins 33 are arranged parallel to the water surface. The rotating shaft 322 passes through the connecting vertical plate, which not only realizes the arrangement of the guide fins 33 and the rotating shaft 322, but also increases the installation space and is conducive to the full utilization of wind power.

[0046] In some embodiments, a fixing plate 40 extends from the bottom of the filter tank 10, and the rotating column 311 is located on the fixing plate 40 and is rotatably connected to the fixing plate 40.

[0047] Specifically, a fixing plate 40 extends outward from the bottom of the filter tank 10, and the rotating column 311 is rotatably connected to the fixing plate 40 to achieve a rotatable connection with the filter tank 10. The fixing plate 40 protrudes relative to the filter tank 10, providing installation space for the wind-powered rotating structure 30 and the pumping component 20, and facilitating the placement of the outlet 212 of the pumping component 20 above the filter tank 10, thereby facilitating the filtration and cleaning of floating debris in the reservoir.

[0048] In some embodiments, the pump cylinder 21 is connected to the filter tank 10 via the connecting bracket 312.

[0049] Specifically, the pump cylinder 21 is rotatably connected to the filter tank 10 via the connecting bracket 312. The connecting bracket 312 includes a horizontal connecting plate. The pump cylinder 21 passes through the horizontal connecting plate and is fixedly connected to it so that it rotates with the connecting bracket 312 and, in turn, with the wind-powered rotating component 32. This allows the connecting part 222 of the spiral pump rod 22 to be stably connected to the rotating shaft 322 of the wind-powered rotating component 32, thereby improving the operational stability of the cleaning device.

[0050] It should be noted that the bottom of the outlet 212 of the pump cylinder 21 is provided with a guide groove 100. The guide groove 100 is inclined, with its higher end located below the outlet 212 and its lower end located above the filter tank 10. Water and floating objects flowing out of the outlet 212 enter the filter tank 10 through the guide groove 100.

[0051] In some embodiments, the cleaning device further includes a transmission rod 50, which is rotatably connected to the connecting assembly 31. The transmission rod 50 is provided with a first parachute wheel 51 and a first gear 52. A second parachute wheel 3221 is provided at one end of the rotating shaft 322 away from the wind turbine blade assembly 321. A second gear 2221 is provided at the connecting portion 222 of the spiral pump rod 22. The first parachute wheel 51 and the second parachute wheel 3221 are meshed together. The first gear 52 and the second gear 2221 are meshed together. The rotating shaft 322 and the connecting portion 222 of the spiral pump rod 22 are connected through the transmission rod 50, so that the spiral pump rod 22 rotates with the rotating shaft 322.

[0052] Specifically, the wind-powered rotating component 32 and the spiral pump rod 22 of the pumping component 20 are connected via the transmission rod 50. A second parasol wheel 3221 is provided at the end of the rotating shaft 322 away from the wind turbine blade assembly 321. The first parasol wheel 51 of the transmission rod 50 is adapted to and meshes with the second parasol wheel 3221. A second gear 2221 is provided at the connecting part 222 of the spiral pump rod 22. The first gear 52 of the transmission rod 50 is adapted to and meshes with the second gear 2221. When the rotating shaft 322 rotates, the second parasol wheel 3221... The first parachute wheel 51 rotates, which in turn drives the transmission rod 50 to rotate, and in turn drives the first gear 52 to rotate. When the first gear 52 rotates, it meshes with the second gear 2221, which in turn drives the second gear 2221 to rotate. The rotation of the second gear 2221 drives the spiral pump rod 22 to rotate. When the spiral pump rod 22 rotates, the spiral part 221 rotates, which brings the water at the bottom of the reservoir from the inlet 211 to the outlet 212 and into the filter tank 10, thereby filtering and cleaning the floating objects on the surface of the reservoir.

[0053] It should be noted that the transmission rod 50 is rotatably connected to the connecting assembly 31. The connecting assembly 31 includes a connecting bracket 312. The transmission rod 50 is rotatably connected to the connecting bracket 312 so as to be stably set relative to the wind-powered rotating component 32 and the water pumping component 20. It can also rotate relative to the connecting bracket 312 to play a transmission role.

[0054] To ensure the stability of the transmission rod 50, a stabilizing plate is provided on the connecting bracket 312, so that the transmission rod 50 can pass through both the stabilizing plate and the connecting cross plate of the connecting bracket 312, and is rotatably connected to both the stabilizing plate and the connecting cross plate.

[0055] In this embodiment, by setting the transmission rod 50, the wind-powered rotating component 32 is connected to the spiral pump rod 22, and the rotation direction of the wind-powered rotating component 32 can be adjusted to match the rotation direction of the spiral pump rod 22. This stably transmits the rotational motion of the wind-powered rotating component 32 to the spiral pump rod 22, which is beneficial to the sustainable operation of the pumping component 20.

[0056] In some embodiments, the filter tank 10 has an arc-shaped structure, and the water pumping component 20 and the wind-powered rotating structure 30 are both located outside the inner ring of the arc-shaped structure.

[0057] Specifically, the filter tank 10 has an arc-shaped structure, and the water pumping component 20 and the wind-powered rotating structure 30 are both located on the outer side of the inner ring of the arc-shaped structure, which can shorten the connection distance between the water pumping component 20 and the wind-powered rotating structure 30 and is beneficial to the connection stability of the water pumping component 20 and the wind-powered rotating structure 30.

[0058] In addition, floating objects on the water surface are easily moved to the edge and gathered by the wind. The water pump 20 is set on the outer side of the inner ring of the arc structure, which can extract the floating objects on the outer edge of the filter tank 10, which helps to improve the cleaning effect of floating objects on the water surface.

[0059] In some embodiments, guide plates 60 are provided at both ends of the filter tank 10, extending away from the filter tank 10, and the two guide plates 60 are arranged away from each other in their extending directions.

[0060] Specifically, the two guide plates 60 are located at both ends of the filter tank 10 and are set far apart from each other. The guide plates 60 can guide the floating objects gathered on the guide plates 60 to the outer side of the inner ring of the filter tank 10, thereby facilitating the water pump 20 to clean the floating objects and water, which helps to improve the floating object cleaning effect of the cleaning device.

[0061] In some embodiments, both the filter tank 10 and the guide plate 60 are provided with a floating structure 70.

[0062] Specifically, the filter tank 10 and the guide plate 60 are provided with the floating structure 70 so that the filter tank 10 and the guide plate 60 float on the surface of the reservoir water, thereby enabling the pumping component 20 and the wind-powered rotating structure 30 to be located on the surface of the reservoir water, so that the wind-powered rotating structure 30 can drive the pumping component 20 to pump water, thereby filtering and cleaning floating objects on the water surface.

[0063] In some embodiments, the filter tank 10 has a connecting lug 80 on its outer side wall away from the pumping component 20, and the connecting lug 80 has a connecting through hole 81 for connecting to the guide column 90 on the reservoir.

[0064] Specifically, the connecting ear 80 is used to fix the cleaning device to the reservoir, so that the position of the cleaning device on the water surface of the reservoir is relatively stable. That is, the cleaning device can clean floating objects at a fixed position on the water surface of the reservoir, and avoid the cleaning device moving randomly on the water surface of the reservoir, which would affect the cleaning effect of the cleaning device.

[0065] It should be noted that the cleaning device is located on the water surface at a corner of the reservoir. The guide post 90 on the reservoir passes through the connecting through hole 81 on the connecting lug 80, so that the cleaning device is rotatably connected to the reservoir and its position in the reservoir is relatively stable, enabling it to clean up floating objects in that corner of the reservoir.

[0066] In practical use, the cleaning device can be installed at multiple locations in the reservoir, so that multiple cleaning devices are responsible for cleaning floating objects at different locations in the reservoir, which is beneficial to improving the cleaning effect of floating objects in the reservoir.

[0067] The following is a detailed description of the usage process of the cleaning device:

[0068] When installing the cleaning device, first, the connecting ear 80 is fitted onto the guide column 90 located at one corner of the reservoir. Under the buoyancy of the water, the floating structure 70 drives the filter tank 10 and the guide plate 60 to float on the water surface, and the water level corresponds to the position of the liquid inlet 211 of the pumping component 20. On this basis, the two guide plates 60 are respectively set close to the two side walls of the corner of the reservoir.

[0069] When the cleaning device is in operation, under the action of wind, debris and floating objects on the surface of the reservoir drift towards the edge of the reservoir. Further, under the action of wind, they are moved to the guide plate 60. Guided by the guide plate 60, they move to the outer side of the inner ring of the filter tank 10. Simultaneously, according to the wind direction, the wind pushes the guide fins 33 to deflect, which in turn drives the connecting bracket 312 to rotate. Under the rotatable action of the rotating shaft, the connecting bracket 312 drives the wind turbine 32 to face the wind direction, which in turn drives the wind turbine blade assembly 321 to rotate. The rotation of the wind turbine blade assembly 321 drives the rotating shaft 322 to rotate, which in turn drives the transmission rod 5. The first bevel gear rotates, which in turn drives the transmission rod 50 to rotate. The transmission rod 50 then drives the first gear 52, which in turn drives the second gear 2221. The second gear 2221 then drives the spiral pump rod 22, which in turn drives the spiral pump rod 22. The spiral pump rod 22 pulls water and floating debris near the surface, discharging them from the outlet 212 at the top of the pump cylinder 21. The discharged floating debris is then discharged into the filter tank 10 for storage under the action of the guide trough 10. The discharged water is also filtered by the filter tank 10, reducing the weight change of the filter tank 10 and keeping the water level near the inlet 211. The guide fins 33 drive the connecting bracket 312 to rotate, positioning the inlet 211 inside the filter tank 10 at a location where wind-driven floating debris gathers, facilitating collection of floating debris. Under the action of the floating structure 70, the height of the filter tank 10 automatically changes with the water level.
