[0026] As described in the background technology, a pumped storage power station is a hydropower station that uses electricity during low load to pump water to an upper reservoir, and releases water to a lower reservoir during peak load to generate electricity. The reservoir of a pumped storage power station is open, and there are usually some garbage or floating aquatic plants floating on the water surface of the reservoir. Since the pumped storage power station uses the water in the reservoir to generate electricity during use, these floating things in the reservoir will damage the generator turbine of the generator once they are sucked into the generator of the pumped storage power station.

[0027] Based on this, the present 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 floating objects entering the generator and causing damage to the generator during the use of the pumped-storage power station.

[0028] The present application is 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, including:

[0030] Filter tank 10;

[0031] The pumping member 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 in the pump barrel 21. The connecting portion 222 protrudes relative to the top of the pump barrel 21. A liquid inlet 211 is provided at the bottom of the pump barrel 21 on a side away from the filter tank 10. A liquid outlet 212 is provided at the top of the side close to the filter tank 10. The liquid outlet 212 is located above the filter tank 10.

[0032] A wind-driven rotating structure 30 is located on the filter tank 10 , and the wind-driven rotating structure 30 is connected to the connecting portion 222 of the screw pump rod 22 ;

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

[0034] Specifically, the pumping member 20 includes a pump barrel 21 and a spiral pump rod 22. The top and bottom of the pump barrel 21 are both closed structures. The spiral pump rod 22 is arranged to pass through the top of the pump barrel 21 so that the spiral portion 221 is located inside the pump barrel 21. The connecting portion 222 is located outside the pump barrel 21 and is protruding relative to the top of the pump barrel 21 so as to be connected to the wind-driven rotating structure 30.

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

[0036] In addition, the two ends of the spiral portion 221 of the spiral pump rod 22 are respectively located at the inner bottom and inner top of the pump barrel 21 to ensure the pumping performance of the pumping member 20. The liquid inlet 211 of the pump barrel 21 is located at the side bottom of the pump barrel 21. The liquid inlet 211 is partially or completely located below the horizontal plane so that the spiral portion 221 located in the pump barrel 21 can contact the water and achieve water pumping. The liquid outlet 212 is located at the side top of the pump barrel 21. When the spiral pump rod 22 rotates, the water located at the liquid inlet 211 can be moved 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 there are more floating objects near the liquid inlet 211, which is conducive to the cleaning device to clean the floating objects on the water surface.

[0037] The pumping member 20 discharges the pumped water containing floating objects into the filter tank 10 through the liquid 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 the floating objects from being on the water surface of the reservoir and affecting the power generation function of the water in the reservoir.

[0038] In this embodiment, by providing a connected water pumping member 20, a wind rotating structure 30 and a filter tank 10, the water pumping member 20 can perform a water pumping action under the drive of the wind rotating structure 30, and discharge the pumped water into the filter tank 10, thereby filtering the debris in the water, and further achieving the effect of cleaning the debris in the reservoir. In addition, the water pumping member 20 includes a pump barrel 21 and a spiral pump rod 22. The liquid 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 liquid inlet 211. The connecting portion 222 of the spiral pump rod 22 is connected to the wind rotating structure 30 so that the spiral pump rod 22 rotates with the wind rotating structure 30. The rotation of the spiral portion 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-driven rotating structure 30 of the present application rotates under the action of wind, thereby driving the spiral pump rod 22 of the pumping member 20 to rotate, achieving the purpose of pumping water, and discharging the pumped water to protect floating objects (debris) into the filter tank 10, thereby achieving automatic cleaning of floating objects on the water surface of the reservoir, which can not only prevent floating objects in the reservoir from entering the generator and causing damage to the generator, but also reduce the cost of cleaning floating objects on the water surface of the reservoir. It is highly practical and suitable for promotion and application.

[0039] In some embodiments, the wind rotating structure 30 includes a connecting assembly 31, a wind rotating member 32 and a guide fin 33, wherein the connecting assembly 31 is rotatably connected to the filter tank 10, the wind rotating member 32 is rotatably connected to the connecting assembly 31, and the guide fin 33 is located on the connecting assembly 31;

[0040] The wind rotating member 32 includes a wind blade group 321 and a rotating shaft 322. One end of the rotating shaft 322 is connected to the center of the wind blade group 321, and the other end is connected to the connecting portion 222 of the screw pump rod 22. The rotating shaft 322 rotates with the wind blade group 321, and the rotating shaft 322 is arranged parallel to the guide fin 33.

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

[0042] The wind rotating member 32 includes a wind blade group 321 and a rotating shaft 322, wherein the rotating shaft 322 is fixedly connected to the center of the wind blade group 321, and the plane where the wind blade group 321 is located is perpendicular to the rotating shaft 322, that is, the wind blade group 321 can rotate under the action of wind force, driving the rotating shaft 322 to rotate in the same manner, and the length direction of the guide fin 33 is arranged parallel to the rotating shaft 322 of the wind rotating member 32, and the corresponding plane where the wind blade group 321 is located is perpendicular to the length direction of the guide fin 33, and when the guide fin 33 is acted upon by wind force, it will deflect to a position where the wind force is perpendicular to the plane of the guide fin 33. Angle, accordingly, the wind blade group 321 is deflected to the side perpendicular to the wind direction, and the wind can act on the wind blade with the maximum force to promote the rotation of the wind blade group 321, and then the rotation shaft 322 is rotated. The setting of the guide fins 33 is conducive to the maximum efficiency rotation of the wind rotating member 32 under the action of wind, so that the pumping member 20 can pump water with maximum efficiency, and realize the filtering and cleaning of floating objects on the surface of the reservoir. The setting of the wind rotating structure 30 can not only improve the cleaning efficiency of the cleaning device, but also maximize the use of wind resources, reduce the cost of the cleaning device, and is conducive to sustainable development and promotion and 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 fin 33 is fixedly connected to the connecting bracket 312, and the rotating shaft 322 of the wind rotating member 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 fin 33 and the wind rotating member 32. When the guide fin 33 is deflected under the action of wind, it drives the connecting bracket 312 and the rotating shaft to deflect at a corresponding angle relative to the filter tank 10. The wind rotating member 32 is also deflected 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. In order 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 connected to each other. The connecting vertical plate is connected to the rotating shaft. 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 is arranged through the connecting vertical plate, which can not only realize the arrangement of the guide fins 33 and the rotating shaft 322, but also increase the arrangement space, which is conducive to the full utilization of wind force.

[0046] In some embodiments, a fixing plate 40 is extended 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 is extended 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 is protruded relative to the filter tank 10, and can provide installation space for the wind rotating structure 30 and the water pumping member 20, so that the liquid outlet 212 of the water pumping member 20 is arranged above the filter tank 10, thereby facilitating the filtration and cleaning of floating objects in the reservoir.

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

[0049] Specifically, the pump barrel 21 is rotatably connected to the filter tank 10 through the connecting bracket 312. The connecting bracket 312 includes a horizontal connecting plate. The pump barrel 21 is arranged through the horizontal connecting plate and is fixedly connected to the horizontal connecting plate so as to rotate with the connecting bracket 312 and then rotate with the wind rotating member 32. This enables the connecting portion 222 of the spiral pump rod 22 to be stably connected to the rotating shaft 322 of the wind rotating member 32, which is beneficial to the operating stability of the cleaning device.

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

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

[0052] Specifically, the wind rotating member 32 is connected to the screw pump rod 22 of the water pumping member 20 through the transmission rod 50, the end of the rotating shaft 322 away from the wind blade group 321 is provided with the second umbrella wheel 3221, the first umbrella wheel 51 of the transmission rod 50 is adapted and meshed with the second umbrella wheel 3221, the connecting portion 222 of the screw pump rod 22 is provided with a second gear 2221, the first gear 52 of the transmission rod 50 is adapted and meshed with the second gear 2221, and when the rotating shaft 322 rotates, the second umbrella wheel 3221 drives the The first umbrella wheel 51 is driven to rotate, and the rotation of the first umbrella wheel 51 drives the transmission rod 50 to rotate, and correspondingly drives the first gear 52 to rotate. When the first gear 52 rotates, it drives the second gear 2221 to rotate through the meshing action with the second gear 2221. The rotation of the second gear 2221 drives the spiral pump rod 22 to rotate. When the spiral pump rod 22 rotates, the spiral portion 221 rotates, and the water at the bottom thereof can be brought from the liquid inlet 211 to the liquid outlet 212 and flow 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 component 31, and the connecting component 31 includes a connecting bracket 312. The transmission rod 50 is rotatably connected to the connecting bracket 312 so as to be stably arranged relative to the wind rotating component 32 and the pumping component 20, and can also rotate relative to the connecting bracket 312 to play a transmission role.

[0054] In order 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 simultaneously pass through the stabilizing plate and the connecting transverse plate of the connecting bracket 312, and be rotationally connected to both the stabilizing plate and the connecting transverse plate.

[0055] In this embodiment, by setting the transmission rod 50, the wind rotating component 32 is connected to the screw pump rod 22, and the rotation direction of the wind rotating component 32 can be adjusted to a rotation direction compatible with the screw pump rod 22, so that the rotational motion of the wind rotating component 32 can be stably transmitted to the screw pump rod 22, which is beneficial to the sustainable operation of the pumping component 20.

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

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

[0058] In addition, floating objects on the water surface are easily moved to the edge and gathered under the influence of wind. The pumping member 20 is arranged on the outside of the inner ring of the arc structure, and can extract floating objects on the outer edge of the filter tank 10, which is beneficial to improving 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 and extend toward a side away from the filter tank 10 , and the two guide plates 60 are arranged away from each other in the extending direction thereof.

[0060] Specifically, the two guide plates 60 are respectively located at the two ends of the filter tank 10 and are set far away from each other. The guide plates 60 can guide the floating objects gathered on the guide plates 60 to move to the outside of the inner ring of the filter tank 10, thereby facilitating the pumping member 20 to clean the floating objects and water, which is beneficial to improving the floating object cleaning effect of the cleaning device.

[0061] In some embodiments, a floating structure 70 is disposed on both the filter tank 10 and the guide plate 60 .

[0062] Specifically, the floating structure 70 is arranged on the filter trough 10 and the guide plate 60, so that the filter trough 10 and the guide plate 60 float on the water surface of the reservoir, and then the pumping member 20 and the wind rotating structure 30 can both be located on the water surface of the reservoir, so that the wind rotating structure 30 can drive the pumping member 20 to perform pumping work, thereby filtering and cleaning floating objects on the water surface.

[0063] In some embodiments, a connecting ear 80 is provided on the outer wall of the filter tank 10 away from the pumping member 20 , and a connecting through hole 81 is provided on the connecting ear 80 , and the connecting through hole 81 is used to connect with a guide column 90 on the reservoir.

[0064] Specifically, the connecting ear 80 is used to fixedly connect 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 cleans floating objects at a fixed position on the reservoir, avoiding the cleaning device from moving randomly on the water surface of the reservoir and affecting the floating object cleaning effect of the cleaning device.

[0065] It should be noted that the cleaning device is located on the water surface in a corner of the reservoir. The guide column 90 on the reservoir passes through the connecting hole 81 on the connecting ear 80, so that the cleaning device is rotatably connected to the reservoir and its position in the reservoir is relatively stable, so that floating objects in this corner of the reservoir can be cleaned.

[0066] When the cleaning device is used in practice, one cleaning device can be set at multiple locations in the reservoir, so that multiple cleaning devices are responsible for cleaning floating objects at different locations of 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 use of the cleaning device:

[0068] When installing the cleaning device, firstly, the connecting ear 80 is put on the guide column 90 located at a 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 member 20. On this basis, the two guide plates 60 are respectively arranged close to the side walls on both sides of the corner of the reservoir;

[0069] When the cleaning device is in operation, under the action of wind, the debris and floating objects on the water surface of the reservoir float to the edge of the reservoir, and are further driven to move to the position of the guide plate 60 under the action of wind, and move to the outer side of the inner ring of the filter tank 10 under the guidance of the guide plate 60. At the same time, according to the wind direction, the wind pushes the guide fins 33 to deflect, and then the guide fins 33 drive the connecting bracket 312 to rotate. Under the rotatable action of the rotating shaft, the connecting bracket 312 drives the wind rotating member 32 toward the wind direction, and then the wind drives the wind blade group 321 to rotate, and the rotation of the wind blade group 321 drives the rotating shaft 322 to rotate, and the rotation of the rotating shaft 322 drives the transmission rod 5 0 rotates, the second bevel gear rotates to drive the first bevel gear to rotate, the first bevel gear rotates to drive the transmission rod 50 to rotate, the transmission rod 50 rotates to drive the first gear 52 to rotate, the first gear 52 rotates to drive the second gear 2221 to rotate, the second gear 2221 rotates to drive the screw pump rod 22 to rotate, the screw pump rod 22 rotates to drive the water body and floating objects near the water surface, and then discharges from the liquid outlet 212 on the upper part of the pump barrel 21, the discharged floating objects are discharged into the filter tank 10 for storage under the action of the guide groove 100, and the discharged water is discharged under the filtering action of the filter tank 10, reducing the weight change of the filter tank 10, and thus making the water level near the liquid inlet 211.
