Technical Field

[0001] The invention relates to the technical field of solar photovoltaic power generation equipment, in particular to a water surface floating solar photovoltaic power generation device. Background Art

[0002] Solar photovoltaic power generation can directly convert sunlight into electrical energy. It is a high-tech method of obtaining electricity without fuel and pollution. It is a clean energy power generation method with relatively good market prospects. Solar photovoltaic power generation devices usually use vast land areas. Due to the shortage of available land area and the increase in the cost of land photovoltaic construction, the use of land will be restricted. The installation of solar power generation devices on water can not only reduce the occupied land area, but also improve the utilization efficiency of the water area. The solar power generation devices set up on the water surface have good lighting conditions, are not easily blocked, and the power generation efficiency is also significantly improved.

[0003] Some floating solar photovoltaic power generation devices built on the water surface of larger lakes, reservoirs, etc., although away from land, still cannot avoid the surface of the photovoltaic panels being adhered to by dust in the air. Since the device floats on the water, it is inevitable that there will be some shaking during the cleaning process, and the wind and waves on the water will also cause the device to float up and down, which makes the workers in the process of cleaning the photovoltaic panels, there are some inconveniences and certain safety hazards. In response to the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a water surface floating solar photovoltaic power generation device, including a cleaning mechanism, the cleaning mechanism also includes a floating base, the top of the floating base is fixedly connected to a support frame, the outer wall of the support frame is fixedly connected to a hydraulic box, and the top of the support frame is fixedly connected to a photovoltaic panel;

[0005] The water washing and softening mechanism comprises a sliding column slidably connected to the inner wall of the hydraulic box, a connecting column rotatably connected to the outer wall of the sliding column, and a rotating plate rotatably connected to the inner wall of the connecting column;

[0006] The water inlet control mechanism comprises a T-shaped bracket fixedly connected to the outer wall of the support frame, a belt pulley is rotatably connected to the outer wall of the T-shaped bracket, and a rotating wheel is fixedly connected to the outer wall of the belt pulley.

[0007] Preferably, the cleaning mechanism also includes a hydraulic plate slidably connected to the inner wall of the hydraulic box, the bottom of the hydraulic plate is fixedly connected to a hydraulic column, the outer wall of the hydraulic column is slidably connected to the inner wall of the hydraulic box, the bottom of the hydraulic column is rotatably connected to a connecting rod 1, and the inner wall of the connecting rod 1 is rotatably connected to a floating plate. The floating plate can move up and down driven by wind and waves, and then connects to the hydraulic column through connecting rod 1, thereby driving the hydraulic plate to move up and down, so as to squeeze the hydraulic oil inside the hydraulic box, thereby providing the most important power source for the subsequent operation of components.

[0008] Preferably, the cleaning mechanism also includes a ball bearing rotatably connected to the inner wall of the floating plate, a fixed column is fixedly connected to the bottom of the hydraulic box, the outer wall of the fixed column is rotatably connected to the outer wall of the ball bearing, a hydraulic pipe is fixedly connected to the inner wall of the hydraulic box, and a telescopic pipe is fixedly connected to the outer wall of the hydraulic pipe. The above-mentioned characteristics of wind and waves pushing the floating plate to move up and down are utilized. When the wind and waves push the floating plate to move, when the force point of the floating plate is at its circular edge, the floating plate rotates upward with the fixed column as the axis through the ball bearing, and through the engagement of the convex teeth at the straight edge of the floating plate and the convex teeth at the opposite straight edge of the floating plate, it is also rotated upward synchronously. When the floating plates on both sides rotate upward, the hydraulic column and the connecting rod are used to push the hydraulic plate upward. When the floating plate The force point of the plate is not at its round edge. The floating plates on both sides are meshed by the convex teeth on the straight edge. The floating plates on both sides move up and down synchronously through the ball bearings. The hydraulic plate is pushed up and down by the hydraulic column and the connecting rod to avoid the situation where the round edge of the floating plate is far away from the fixed column, and the round edge of one side of the floating plate is stressed while the other side is not stressed. The unilateral thrust will cause the hydraulic plate to tilt when moving upward, thereby increasing the resistance it encounters when moving upward, making it impossible for the brush to move down to the lowest point to clean the lowest point of the photovoltaic panel. In addition, when the hydraulic plate moves up and down for a long time, its edges will be greatly worn, causing the hydraulic oil inside the hydraulic box to leak accidentally, causing water resources to be polluted to a certain extent.

[0009] Preferably, the cleaning mechanism also includes a telescopic spring 1 fixedly connected to the inner wall of the telescopic tube, a connecting block fixedly connected to the outer wall of the telescopic tube, a brush rotatably connected to the inner wall of the connecting block, a gear 1 fixedly connected to the outer wall of the brush, a rack 1 fixedly connected to the outer wall of the photovoltaic panel, the outer wall of the rack 1 is meshingly connected with the outer wall of the gear 1, and the wind and waves on the surface of larger lakes and reservoirs can be used to push the floating plate to move up and down. A hydraulic box is provided, which drives the floating plate to move up and down under the push of wind and waves, and drives the hydraulic plate to move up and down through the hydraulic column and the connecting rod 1. When the hydraulic plate moves upward, the hydraulic oil on the top thereof is squeezed so that it passes through the hydraulic pipe and enters the interior of the telescopic tube, so that the telescopic tube extends outward, and when the telescopic tube is extended, the floating plate moves upward. When the tube extends outward, the brush can move downward through the connecting block, and when the brush moves, the gear 1 is meshed with the rack 1, so that the brush rotates continuously and contacts the photovoltaic panel. When the hydraulic plate moves downward, a certain negative pressure is generated on its top, and the telescopic spring 1 pulls the telescopic tube to retract, so that the hydraulic oil in the telescopic tube and the hydraulic tube flows back into the hydraulic box, and when the telescopic tube retracts, it also drives the brush to rotate continuously and contact the photovoltaic panel, so that when the floating plate moves up and down, the brush rotates continuously through the transmission of the component, and the dust and impurities adhered to the surface of the photovoltaic panel are cleared, so as to prevent the surface of the photovoltaic panel from being blocked by dust and impurities, thereby reducing the contact area between the surface of the photovoltaic panel and the sunlight, thereby reducing the power generation efficiency of the photovoltaic panel.

[0010] Preferably, the water washing and softening mechanism also includes a reciprocating screw fixedly connected to the outer wall of the rotating plate, the bottom of the sliding column is fixedly connected to the top of the hydraulic plate, the top of the hydraulic box is fixedly connected to a fixed bracket, the inner wall of the fixed bracket is rotatably connected to the outer wall of the reciprocating screw, the outer wall of the reciprocating screw is rotatably connected to a water tank, and the inner wall of the water tank is slidably connected to a piston rod. The fixed bracket can limit the reciprocating screw to rotate in a prescribed manner to prevent deviation during rotation, thereby affecting the transmission of subsequent components. The subsequent components slide back and forth in the groove on the outer wall of the reciprocating screw, so that the rotation force of the reciprocating screw is transmitted to the piston rod, so that the piston rod can move back and forth at the inner wall of the water tank, providing power support for the operation of subsequent components.

[0011] Preferably, the water washing and softening mechanism also includes a movable block rotatably connected to the top of the piston rod, the outer wall of the movable block is meshingly connected to the outer wall of the reciprocating screw rod, the outer wall of the piston rod is fixedly connected to a piston plate, the outer wall of the piston plate is slidably connected to the inner wall of the water tank, the inner wall of the water tank is fixedly connected to a one-way valve 1, the outer wall of the one-way valve 1 is fixedly connected to a water inlet pipe, the outer wall of the water inlet pipe is fixedly connected to the bottom of the water tank, and the outer wall of the water inlet pipe is fixedly connected to the inner wall of the support frame. When the piston rod moves back and forth, it drives the piston plate to slide back and forth inside the water tank. When the piston plate slides, water can be extracted, so that the water passes through the water inlet pipe, passes through the one-way valve 1, and enters the interior of the water tank, thereby realizing the operation of extracting water.

[0012] Preferably, the water washing and softening mechanism also includes a hose fixedly connected to the bottom of the water inlet pipe, a one-way valve 2 is fixedly connected to the inner wall of the water tank, a water outlet pipe is fixedly connected to the outer wall of the one-way valve 2, the outer wall of the water outlet pipe is rotatably connected to the inner wall of the brush, a water outlet hole is opened on the outer wall of the brush, and a sliding column is provided by utilizing the characteristic of the hydraulic plate moving up and down. When the hydraulic plate moves up and down, the sliding column is synchronously driven to move up and down, and then the rotating plate is rotated through the transmission of the connecting column. When the rotating plate rotates, the reciprocating screw is driven to rotate, and then the movable block slides back and forth in the groove of the reciprocating screw, driving the piston rod to make the piston plate move back and forth inside the water tank, and the piston plate When it moves inward, negative pressure is generated inside the water tank, so that the water under the floating base can pass through the hose and the water inlet pipe, through the one-way valve 1 and enter the inside of the water tank. When the piston plate moves outward, the water inside the water tank is squeezed through the one-way valve 2, and flows out from the water outlet hole through the water outlet pipe to the surface of the photovoltaic panel, so that the bird droppings and some relatively sticky impurities on the surface of the photovoltaic panel can be washed and softened by the action of the water flow, so that the brush can clean them up when it rotates to clean, and avoids the bird droppings and some relatively sticky impurities falling on them, agglomerating under the sunlight, and then tightly adhering to the surface of the photovoltaic panel, making it difficult for the brush to completely remove them when it rotates to clean.

[0013] Preferably, the water inlet control mechanism also includes a belt mounted on the outer wall of the rotating wheel, a gear 2 is rotatably connected to the outer wall of the T-shaped bracket, a belt is mounted on the outer wall of the gear 2, and a telescopic tooth is slidably connected to the inner wall of the gear 2.

Utilizing the characteristic that the piston plate can move back and forth, a connecting rod 2 is provided, so that when the piston plate moves back and forth, the connecting rod 2 is synchronously driven to move back and forth, and when the connecting rod 2 moves outward, the rack 2 is driven to move outward. At this time, the inclined surface of the teeth of the rack 2 contacts the inclined surface of the teeth of the telescopic tooth, pushing the telescopic tooth to retract inward, and being unable to drive the gear 2 to rotate. When it moves inward, it will synchronously drive rack 2 to move inward. At this time, the vertical surface of the teeth of rack 2 contacts the vertical surface of the telescopic teeth. When rack 2 moves inward, it will drive gear 2 to rotate, and then drive the rotating wheel to rotate through the belt and pulley, so that the hose will only penetrate into the water when the rotating wheel rotates it to the lowest point, so that water can enter the hose through the filter plate and then continue to rise, avoiding continuous use of water to clean the surface of the photovoltaic panel, making the surface of the photovoltaic panel in a state of water for a long time, so that the photovoltaic panel will be affected by the water on the surface when performing photoelectric conversion, so that the efficiency of photoelectric conversion is reduced, and then the power generation efficiency of the photovoltaic panel is discounted.

[0015] The present invention has the following beneficial effects:

[0016] (1) The present invention utilizes the characteristic that the wind and waves on the surface of larger lakes and reservoirs can push the floating plate to move up and down, and sets a hydraulic box. Under the push of the wind and waves, the floating plate is driven to move up and down, and the hydraulic plate is pushed up and down by the hydraulic column and the connecting rod. When the hydraulic plate moves upward, the hydraulic oil on the top is squeezed to pass through the hydraulic pipe and enter the inside of the telescopic tube, so that the telescopic tube extends outward. When the telescopic tube extends outward, the brush can move downward through the connecting block, and when the brush moves, the gear 1 and the rack 1 are meshed to make the brush rotate continuously and contact with the light. When the hydraulic plate moves downward, a certain negative pressure is generated on its top, and the telescopic spring pulls the telescopic tube to retract, so that the hydraulic oil in the telescopic tube and the hydraulic tube flows back to the hydraulic box, and when the telescopic tube retracts, it will also drive the brush to rotate continuously and contact the photovoltaic panel. In this way, when the floating plate moves up and down, the brush can be driven by the transmission of the component to make it rotate continuously and remove dust and impurities adhered to the surface of the photovoltaic panel to prevent the surface of the photovoltaic panel from being blocked by dust and impurities, thereby reducing the contact area between the surface of the photovoltaic panel and the sunlight, thereby reducing the power generation efficiency of the photovoltaic panel.

[0017] (2) The present invention utilizes the above-mentioned characteristic that the wind and waves drive the floating plate to move up and down. When the wind and waves drive the floating plate to move, when the force point of the floating plate is at its circular edge, the floating plate rotates upward with the fixed column as the axis through the ball bearings, and the convex teeth at the straight edge of the floating plate and the meshing of the convex teeth at the straight edge of the opposite floating plate are used to make it rotate upward synchronously. When the floating plates on both sides rotate upward, the hydraulic column and the connecting rod are used to push the hydraulic plate upward. When the force point of the floating plate is not at its circular edge, the floating plates on both sides are meshed by the convex teeth at the straight edge, and the floating plates on both sides are synchronously rotated upward through the ball bearings. The hydraulic plate is pushed up and down by the hydraulic column and the connecting rod to avoid the situation that the round edge of the floating plate is far away from the fixed column, and the round edge of one side of the floating plate is stressed while the other side is not stressed. The unilateral thrust will cause the hydraulic plate to tilt when it moves upward, thereby increasing the resistance it encounters when moving upward, making it impossible for the brush to move down to the lowest point to clean the lowest point of the photovoltaic panel. In addition, when the hydraulic plate moves up and down for a long time, its edges will be greatly worn, causing the hydraulic oil inside the hydraulic box to leak accidentally, causing water resources to be polluted to a certain extent.

[0018] (3) The present invention utilizes the characteristic of the hydraulic plate moving up and down to set a sliding column. When the hydraulic plate moves up and down, it synchronously drives the sliding column to move up and down, and then through the transmission of the connecting column, the rotating plate is rotated. When the rotating plate rotates, it drives the reciprocating screw to rotate, and then the movable block slides back and forth in the groove of the reciprocating screw, driving the piston rod to make the piston plate move back and forth inside the water tank. When the piston plate moves inward, negative pressure is generated inside the water tank, so that the water under the floating base can pass through the hose and the water inlet pipe and pass through the one-way valve 1 to enter the inside of the water tank. When the piston plate moves outward, the water squeezed inside the water tank passes through the one-way valve 2 and flows out from the water outlet hole to the surface of the photovoltaic panel through the water outlet pipe, so that the bird droppings and some relatively sticky impurities on the surface of the photovoltaic panel can be washed and softened under the action of the water flow, so that the brush can clean them up when rotating and cleaning, avoiding the bird droppings and some relatively sticky impurities from falling on them and agglomerating under the irradiation of sunlight, and then tightly adhering to the surface of the photovoltaic panel, making it difficult for the brush to completely remove them when rotating and cleaning.

[0019] (4) The present invention utilizes the characteristic that the piston plate can move back and forth, and sets a connecting rod 2, so that when the piston plate moves back and forth, it synchronously drives the connecting rod 2 to move back and forth. When the connecting rod 2 moves outward, it drives the rack 2 to move outward. At this time, the inclined surface of the teeth of the rack 2 contacts the inclined surface of the telescopic teeth, pushing the telescopic teeth to retract inward, and cannot drive the gear 2 to rotate. When the connecting rod 2 moves inward, it synchronously drives the rack 2 to move inward. At this time, the vertical surface of the teeth of the rack 2 contacts the vertical surface of the telescopic teeth. When the rack 2 moves inward, it will drive the gear 2 to rotate, and then drive the rotating wheel to rotate through the belt and the pulley, so that the hose will only penetrate into the water when the rotating wheel rotates it to the lowest point, so that the water can enter the hose through the filter plate and then continue to rise, avoiding continuous use of water to clean the surface of the photovoltaic panel, so that the surface of the photovoltaic panel is in a state of water for a long time, so that when the photovoltaic panel performs photoelectric conversion, it is affected by the water on the surface, so that the efficiency of photoelectric conversion is reduced, and then the power generation efficiency of the photovoltaic panel is discounted.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] For example, see Figure 1-Figure 5 The present invention is a water-surface floating solar photovoltaic power generation device, comprising a cleaning mechanism 1, the cleaning mechanism 1 further comprising a floating base 101, a support frame 102 is fixedly connected to the top of the floating base 101, a hydraulic box 103 is fixedly connected to the outer wall of the support frame 102, and a photovoltaic panel 104 is fixedly connected to the top of the support frame 102;

[0034] The water washing and softening mechanism 2 comprises a sliding column 201 slidably connected to the inner wall of the hydraulic box 103, a connecting column 202 is rotatably connected to the outer wall of the sliding column 201, and a rotating plate 203 is rotatably connected to the inner wall of the connecting column 202;

[0035] The water inlet control mechanism 3 includes a T-shaped bracket 301 fixedly connected to the outer wall of the support frame 102 , a pulley 302 is rotatably connected to the outer wall of the T-shaped bracket 301 , and a rotating wheel 303 is fixedly connected to the outer wall of the pulley 302 .

[0036] The cleaning mechanism 1 also includes a hydraulic plate 105 slidably connected to the inner wall of the hydraulic box 103, and a hydraulic column 106 is fixedly connected to the bottom of the hydraulic plate 105.

The bottom of the hydraulic column 106 is rotatably connected to a connecting rod 107, and the inner wall of the connecting rod 107 is rotatably connected to a floating plate 108. The floating plate 108 can move up and down driven by wind and waves, and then connects to the hydraulic column 106 through the connecting rod 107, thereby driving the hydraulic plate 105 to move up and down, so as to squeeze the hydraulic oil inside the hydraulic box 103, thereby providing the main power source for the subsequent operation of components.

[0037] The cleaning mechanism 1 also includes a ball 109 rotatably connected to the inner wall of the floating plate 108, a fixed column 110 is fixedly connected to the bottom of the hydraulic box 103, the outer wall of the fixed column 110 is rotatably connected to the outer wall of the ball 109, a hydraulic pipe 111 is fixedly connected to the inner wall of the hydraulic box 103, and a telescopic pipe 112 is fixedly connected to the outer wall of the hydraulic pipe 111. By utilizing the above-mentioned characteristics of the wind and waves pushing the floating plate 108 to move up and down, when the wind and waves push the floating plate 108 to move, when the force point of the floating plate 108 is at its circular edge, the floating plate 108 rotates upward with the fixed column 110 as the axis through the ball 109, and through the engagement of the convex teeth at the straight edge of the floating plate 108 and the convex teeth at the opposite straight edge of the floating plate 108, it is also synchronously rotated upward. When the floating plates 108 on both sides rotate upward, the hydraulic column 106 and the connecting rod 107 are used to push the hydraulic plate 10 5 moves upward. When the force point of the floating plate 108 is not at its round edge, the floating plates 108 on both sides are meshed by the convex teeth at the straight edge, and the floating plates 108 on both sides are moved up and down synchronously through the ball 109. The hydraulic plate 105 is pushed up and down by the hydraulic column 106 and the connecting rod 107 to avoid that the round edge of the floating plate 108 is far away from the fixed column 110, and the round edge of one side of the floating plate 108 is stressed while the other side is not stressed. The unilateral thrust will cause the hydraulic plate 105 to tilt to a certain extent when moving upward, thereby increasing the resistance it encounters when moving upward, making it impossible for the brush 115 to move downward to the lowest point to clean the lowest point of the photovoltaic panel 104, and when the hydraulic plate 105 moves up and down for a long time, its edge will be greatly worn, causing the accident of hydraulic oil leakage in the hydraulic box 103, causing water resources to be polluted to a certain extent.

A hydraulic box 103 is set, and the floating plate 108 is driven by the wind and waves to move up and down, and the hydraulic plate 105 is pushed up and down through the hydraulic column 106 and the connecting rod 107. When the hydraulic plate 105 moves upward, the hydraulic oil on the top is squeezed so that it passes through the hydraulic pipe 111 and enters the interior of the telescopic tube 112, so that the telescopic tube 112 extends outward. When the tube 112 extends outward, the brush 115 can move downward through the connecting block 114, and when the brush 115 moves, the gear 116 and the rack 117 are meshed to make the brush 115 rotate continuously and contact the photovoltaic panel 104. When the hydraulic plate 105 moves downward, a certain negative pressure is generated on its top, and the telescopic spring 113 pulls the telescopic tube 112 to retract, so that the hydraulic oil in the telescopic tube 112 and the hydraulic tube 111 flows back into the hydraulic box 103, and when the telescopic tube 112 retracts, it also drives the brush 115 to rotate continuously and contact the photovoltaic panel 104, so that when the floating plate 108 moves up and down, the brush 115 is driven to rotate continuously through the transmission of the component, and the dust and impurities adhered to the surface of the photovoltaic panel 104 are removed, so as to prevent the surface of the photovoltaic panel 104 from being blocked by dust and impurities, thereby reducing the contact area between the surface of the photovoltaic panel 104 and the sunlight, thereby reducing the power generation efficiency of the photovoltaic panel.

Through the fixed bracket 205, the reciprocating screw 204 can be restricted to rotate in a prescribed manner to prevent deviation during rotation, thereby affecting the transmission of subsequent components. The subsequent components slide back and forth at the groove on the outer wall of the reciprocating screw 204, so that the rotation force of the reciprocating screw 204 is transmitted to the piston rod 207, so that the piston rod 207 can move back and forth at the inner wall of the water tank 206, providing power support for the operation of subsequent components.

Utilizing the characteristic of the hydraulic plate 105 moving up and down, a sliding column 201 is set. When the hydraulic plate 105 moves up and down, the sliding column 201 is synchronously driven to move up and down, and then the transmission of the connecting column 202 causes the rotating plate 203 to rotate. When the rotating plate 203 rotates, the reciprocating screw rod 204 is driven to rotate, and then the movable block 208 slides back and forth in the groove of the reciprocating screw rod 204, driving the piston rod 207 to make the piston plate 209 inside the water tank 206. When the piston plate 209 moves back and forth, when the piston plate 209 moves inward, negative pressure is generated inside the water tank 206, so that the water under the floating base 101 can pass through the hose 212 and the water inlet pipe 211, pass through the one-way valve 1 210 and enter the inside of the water tank 206. When the piston plate 209 moves outward, the water inside the water tank 206 is squeezed through the one-way valve 213, and flows out from the water outlet hole 215 through the water outlet pipe 214 to the surface of the photovoltaic panel 104, so that the bird droppings and some relatively sticky impurities on the surface of the photovoltaic panel 104 can be washed and softened by the action of the water flow, so that the brush 115 can clean them up when rotating and cleaning, and avoids the bird droppings and some relatively sticky impurities falling on them, agglomerating under the irradiation of sunlight, and then tightly adhering to the surface of the photovoltaic panel 104, making it difficult for the brush 115 to completely remove them when rotating and cleaning.

[0042] The water inlet control mechanism 3 also includes a belt 304 sleeved on the outer wall of the rotating wheel 303, a gear 2 305 is rotatably connected to the outer wall of the T-shaped bracket 301, a belt 304 is sleeved on the outer wall of the gear 2 305, and a telescopic tooth 306 is slidably connected to the inner wall of the gear 2 305. The belt 304 can make the gear 2 305 drive the pulley 302 to rotate when it rotates, realize the transmission of force, and allow the gear 2 305 and the pulley 302 to rotate synchronously. The telescopic tooth 306 is used to realize that when the subsequent components are engaged with it, it can drive the gear 2 305 to rotate, and when it is not engaged with it, the gear 2 305 cannot be rotated.

[0043] The water inlet control mechanism 3 also includes a telescopic spring 2 307 fixedly connected to the outer wall of the telescopic tooth 306, a connecting rod 2 308 fixedly connected to the outer wall of the piston plate 209, the outer wall of the connecting rod 2 308 is slidably connected to the inner wall of the water tank 206, the bottom of the connecting rod 2 308 is fixedly connected to a rack 2 309, and the inner wall of the hose 212 is fixedly connected to a filter plate 310. By utilizing the characteristic that the piston plate 209 can move back and forth, a connecting rod 2 308 is provided, so that when the piston plate 209 moves back and forth, the connecting rod 2 308 is synchronously driven to move back and forth, and when the connecting rod 2 308 moves outward, the rack 2 309 is driven to move outward. At this time, the inclined surface of the teeth of the rack 2 309 contacts the inclined surface of the teeth of the telescopic tooth 306, pushing the telescopic tooth 306 to retract inward, and failing to drive the gear 2 305 to rotate. When the second connecting rod 308 moves inward, it synchronously drives the second rack 309 to move inward. At this time, the vertical surface of the teeth of the second rack 309 contacts the vertical surface of the teeth of the telescopic teeth 306. When the second rack 309 moves inward, it will drive the second gear 305 to rotate, and then drive the rotating wheel 303 to rotate through the belt 304 and the pulley 302, so that the hose 212 will only penetrate into the water when the rotating wheel 303 rotates it to the lowest point, so that the water can enter the hose 212 through the filter plate 310, and then continue to rise, avoiding continuous use of water to clean the surface of the photovoltaic panel 104, so that the surface of the photovoltaic panel 104 is in a state of water for a long time, so that when the photovoltaic panel 104 performs photoelectric conversion, it is affected by the water on the surface, so that the efficiency of photoelectric conversion is reduced, and then the power generation efficiency of the photovoltaic panel 104 is discounted.

[0044] A specific application of this embodiment is as follows: before using the device, the device is first installed at a desired location, and a hydraulic box 103 is set. Under the push of wind and waves, the floating plate 108 is driven to move up and down, and the hydraulic plate 105 is pushed up and down by the hydraulic column 106 and the connecting rod 107. When the hydraulic plate 105 moves upward, the hydraulic oil on the top is squeezed to pass through the hydraulic pipe 111 and enter the interior of the telescopic tube 112, so that the telescopic tube 112 extends outward. When the telescopic tube 112 extends outward, the brush 115 can be moved downward through the connecting block 114, and when the brush 115 moves, the gear 116 and the rack 117 are meshed to make the brush 115 move downward. The brush 115 rotates continuously and contacts the photovoltaic panel 104. When the hydraulic plate 105 moves downward, a certain negative pressure is generated on its top, and the telescopic spring 113 pulls the telescopic tube 112 to retract, so that the hydraulic oil in the telescopic tube 112 and the hydraulic tube 111 flows back into the hydraulic box 103. When the telescopic tube 112 retracts, the brush 115 is also driven to rotate continuously and contact the photovoltaic panel 104. In this way, when the floating plate 108 moves up and down, the brush 115 is driven by the transmission of the component to rotate continuously and remove dust and impurities adhering to the surface of the photovoltaic panel 104, so as to prevent the surface of the photovoltaic panel 104 from being blocked by dust and impurities, thereby reducing the contact area between the surface of the photovoltaic panel 104 and the sunlight. As a result, the power generation efficiency of the photovoltaic panel is reduced. When the wind and waves push the floating plate 108 to move, when the force point of the floating plate 108 is at its circular edge, the floating plate 108 rotates upward with the fixed column 110 as the axis through the ball 109, and through the convex teeth at the straight edge of the floating plate 108 and the meshing of the convex teeth at the straight edge of the opposite floating plate 108, it is also rotated upward synchronously. When the floating plates 108 on both sides rotate upward, the hydraulic column 106 and the connecting rod 107 are used to push the hydraulic plate 105 upward. When the force point of the floating plate 108 is not at its circular edge, the floating plates 108 on both sides are meshed by the convex teeth at the straight edge, and the floating plates 108 on both sides are synchronously rotated through the ball 109. The hydraulic plate 105 is pushed up and down by the hydraulic column 106 and the connecting rod 107 to move up and down, so as to avoid the situation that the round edge of the floating plate 108 is far away from the fixed column 110, and the round edge of one side of the floating plate 108 is stressed while the other side is not stressed. The unilateral thrust will cause the hydraulic plate 105 to tilt when moving upward, thereby increasing the resistance it encounters when moving upward, making it impossible for the brush 115 to move downward to the lowest point to clean the lowest point of the photovoltaic panel 104. In addition, when the hydraulic plate 105 moves up and down for a long time, its edge will be greatly worn, causing the hydraulic oil inside the hydraulic box 103 to leak accidentally, causing water resources to be polluted to a certain extent.

[0045] Taking advantage of the fact that the hydraulic plate 105 moves up and down, a sliding column 201 is provided. When the hydraulic plate 105 moves up and down, the sliding column 201 is synchronously driven to move up and down, and then the rotating plate 203 is rotated through the transmission of the connecting column 202. When the rotating plate 203 rotates, the reciprocating screw rod 204 is driven to rotate, and then the movable block 208 slides back and forth in the groove of the reciprocating screw rod 204, driving the piston rod 207 to make the piston plate 209 move back and forth inside the water tank 206. When the piston plate 209 moves inward, negative pressure is generated inside the water tank 206, so that the water under the floating base 101 can pass through the hose 212 and the water inlet pipe 211, through The one-way valve 1 210 enters the interior of the water tank 206. When the piston plate 209 moves outward, the water inside the water tank 206 is squeezed through the one-way valve 213, and flows out from the water outlet hole 215 through the water outlet pipe 214 to the surface of the photovoltaic panel 104, so that the bird droppings and some relatively sticky impurities on the surface of the photovoltaic panel 104 can be washed and softened by the action of the water flow, so that the brush 115 can clean them up when rotating for cleaning, and avoid the bird droppings and some relatively sticky impurities falling on them, agglomerating under the sunlight, and then tightly adhering to the surface of the photovoltaic panel 104, making it difficult for the brush 115 to completely remove them when rotating for cleaning.

[0046] Taking advantage of the feature that the piston plate 209 can move back and forth, a connecting rod 2 308 is provided, so that when the piston plate 209 moves back and forth, the connecting rod 2 308 is synchronously driven to move back and forth. When the connecting rod 2 308 moves outward, the rack 2 309 is driven to move outward. At this time, the inclined surface of the teeth of the rack 2 309 contacts the inclined surface of the teeth of the telescopic tooth 306, pushing the telescopic tooth 306 to retract inward, and being unable to drive the gear 2 305 to rotate. When the connecting rod 2 308 moves inward, the rack 2 309 is synchronously driven to move inward. At this time, the vertical surface of the teeth of the rack 2 309 contacts the vertical surface of the teeth of the telescopic tooth 306. When moving inward, it will drive gear 2 305 to rotate, and then drive the rotating wheel 303 to rotate through the belt 304 and the pulley 302, so that the hose 212 will not penetrate into the water until the rotating wheel 303 rotates it to the lowest point, so that the water can enter the hose 212 through the filter plate 310, and then continue to rise, so as to avoid continuous use of water to clean the surface of the photovoltaic panel 104, so that the surface of the photovoltaic panel 104 is in a state of water for a long time, so that when the photovoltaic panel 104 performs photoelectric conversion, it is affected by the water on the surface, so that the efficiency of photoelectric conversion is reduced, and the power generation efficiency of the photovoltaic panel 104 is discounted.
