[0027] BRIEF DESCRIPTION OF DRAWINGS

[0028] The present application will be further described below in conjunction with the drawings and examples, but it is not limited to the basis of the application.

[0029] Embodiment of the present application: a cable-stayed water photovoltaic array, as shown in Figures 1 to 2 ​​​​​As shown, it comprises a plurality of mounting racks 1, a plurality of mounting racks 1 are sequentially connected together through the cable 3, the top surface of the mounting rack 1 is provided with a plurality of photovoltaic panels 2, the inside of the mounting rack 1 is connected with a filter frame 4, both sides of the inside of the mounting rack 1 and the filter frame 4 are fixed with a floating capsule 5, the inside of the floating capsule 5 is respectively provided with an air suction assembly 6 and an exhaust assembly 8, wherein the air suction assembly 6 is arranged on the side away from the filter frame 4, the exhaust assembly 8 is arranged on the side close to the filter frame 4, the top end of the air suction assembly 6 is communicated with the outside through the air inlet pipe 7 penetrating the mounting rack 1, and the top end of the exhaust assembly 8 is communicated with the outside through the exhaust pipe 9 penetrating the mounting rack 1.

[0030] In the working process, first, the inside of the floating capsule 5 is filled with air through the air suction assembly 6 during use, and the air pressure in the inside of the two floating capsules 5 is equal, then the mounting rack 1 is put into the water, and the mounting rack 1 is lifted by the buoyancy of the floating capsule 5, so that the photovoltaic panel 2 can float on the water surface to generate electricity. A plurality of mounting racks 1 can be connected to each other through the cable 3, and the plurality of mounting racks 1 connected through the cable 3 and the filter frame 4 can filter the floating objects on the water surface and purify the water quality. When it is necessary to adjust the angle of the photovoltaic panel 2, according to the direction of the inclination angle, the exhaust assembly 8 in the inside of one side floating capsule 5 is adjusted, the air in the inside of the floating capsule 5 is discharged through the exhaust pipe 9 through the exhaust assembly 8, so that the buoyancy of the floating capsule 5 is reduced, at this time the mounting rack 1 drives the photovoltaic panel 2 to incline, and then the air outside the floating capsule 5 can be sucked into the inside of the floating capsule 5 through the air suction assembly 6 in the inside of the floating capsule 5, so that the mounting rack 1 is reset, the inclination angle of the photovoltaic panel 2 is adjusted by the buoyancy, compared with the traditional supporting parts, there are fewer mechanical structures exposed outside, which avoids the corrosion of the exposed mechanical structure and causes the equipment to fail, and the use is more stable.

[0031] As shown in Figures 2 to 3 The inside of the exhaust pipe 9 is slidably connected with a one-way valve 10, and the bottom end of the one-way valve 10 is fixed with a support frame 11. When the one-way valve 10 is arranged in the inside of the exhaust pipe 9, when the water flow enters the inside of the exhaust pipe 9 due to the large floating of the water surface, the one-way valve 10 can effectively prevent the water from entering the inside of the floating capsule 5 and causing damage to the equipment in the inside of the floating capsule 5, and when the gas in the inside of the floating capsule 5 is discharged through the exhaust pipe 9, the airflow will lift the water flow in the inside of the exhaust pipe 9 to form a water column, and the water column is sprayed out of the exhaust pipe 9 and drops on the surface of the photovoltaic panel 2, which plays a certain cleaning effect on the surface.

[0032] As shown in Figure 3As shown, the bottom end of the support frame 11 is fixed with an adjusting spring 13, the bottom end of the adjusting spring 13 is fixed with a fixed frame 14, the fixed frame 14 is fixedly connected with the mounting frame 1, a plurality of through holes are formed in the fixed frame 14, a power-on electromagnet 15 is fixedly arranged in the fixed frame 14, an adjusting magnet 12 is fixedly arranged in the support frame 11, the magnetism of the power-on electromagnet 15 after being electrified is adapted to the magnetism of the adjusting magnet 12, and a telescopic rod is arranged between the support frame 11 and the fixed frame 14 and in the adjusting spring 13. In actual use, the staff can adjust the magnetism of the power-on electromagnet 15 according to the gas discharge amount in the floating capsule 5, change the force applied to the adjusting magnet 12 by adjusting the magnetism of the power-on electromagnet 15, drive the support frame 11 to compress or stretch the adjusting spring 13, and then drive the one-way valve 10 to slide in the exhaust pipe 9, so as to adjust the position of the one-way valve 10 in the exhaust pipe 9. In this way, the content of the water flow accumulated in the exhaust pipe 9 can be adjusted, so as to prevent the situation that the discharged gas pressure is too small to push the water column out.

[0033] As shown in Figure 3 , the upper and lower ends of the one-way valve 10 are fixedly provided with sealing rubber rings 16, and the sealing rubber rings 16 are attached to the inner wall of the exhaust pipe 9. During the sliding of the one-way valve 10, the sealing effect between the one-way valve 10 and the exhaust pipe 9 can be effectively ensured by the sealing rubber rings 16, so as to prevent water leakage.

[0034] As shown in Figure 4 , the top end of the exhaust pipe 9 is provided with a separation net 17, and the two ends of the separation net 17 are fixedly connected with the photovoltaic panel 2. When the external water flow drops into the exhaust pipe 9, it will first flow through the separation net 17. The separation net 17 can effectively filter impurities in the water flow, preventing the exhaust pipe 9 from being blocked.

[0035] As shown in Figure 4 , a plurality of elastic sheets 19 are fixedly arranged on one side of the separation net 17 close to the exhaust pipe 9, and a hollow ball 18 is fixedly arranged at the end of the elastic sheet 19 away from the separation net 17. When the water column in the exhaust pipe 9 is discharged through the separation net 17, it will backwash the separation net 17, preventing the separation net 17 from being blocked and affecting the subsequent water inflow effect. During this process, the separation net 17 will deform and vibrate to a certain extent. During this process, the separation net 17 will drive the hollow ball 18 to reciprocatingly knock the mounting frame 1 through the elastic sheet 19. The vibration generated by the knocking can accelerate the sliding of the water droplets on the surface of the photovoltaic panel 2, thereby accelerating the cleaning effect on the surface of the photovoltaic panel 2.

[0036] As shown in Figures 4 to 5As shown, a pair of flow guides 20 are fixed inside the exhaust pipe 9 below the separation net 17, a limiting rod 21 is fixed inside the flow guides 20, an extrusion rod 22 is slidably connected to the bottom of the limiting rod 21, a hollow block 23 is fixed to one end of the extrusion rod 22, a liquid storage bag 24 is arranged above the extrusion rod 22, and the liquid storage bag 24 is fixedly connected to the flow guide 20. After the water flow in the exhaust pipe 9 accumulates to a certain extent, the water level gradually rises until the flow guide 20 is completely submerged, and in this process, the hollow block 23 will drive the extrusion rod 22 to slide along the limiting rod 21 under the action of buoyancy until the extrusion rod 22 extrudes the liquid storage bag 24. After the liquid storage bag 24 is extruded, it will deform to spray the cleaning liquid stored inside, and the sprayed cleaning liquid mixes with the water, further improving the cleaning effect on the photovoltaic panel 2.

[0037] As shown in Figure 5 A support rod 25 is fixed between a pair of hollow blocks 23, a rotating frame 26 is rotatably connected to the outside of the support rod 25, and a rotating blade 27 is fixed to the outside of the rotating frame 26. During the water column discharge process, the flow of water flow will simultaneously drive the rotating frame 26 and the rotating blade 27 to rotate around the support rod 25, and the rotating blade 27 can promote the mixing effect of the cleaning liquid and water during rotation, further enhancing the cleaning effect.

[0038] As shown in Figures 6 to 8 A partition plate 28 is fixed to the top end of the mounting frame 1 above the air inlet pipe 7, a plurality of air exchange holes 29 are formed on both sides of the partition plate 28, an arc-shaped elastic sheet 30 is arranged outside the air exchange hole 29, and the arc-shaped elastic sheet 30 is fixedly connected to the partition plate 28. When the air suction assembly 6 sucks external air through the air inlet pipe 7, the external air enters the air inlet pipe 7 through the air exchange hole 29 inside the partition plate 28, and the arrangement of the arc-shaped elastic sheet 30 can effectively guide the water outside to prevent water from entering the air inlet pipe 7.

[0039] The arc-shaped elastic sheet 30 is fixed to the bottom surface of the partition plate 28, and a connecting rod 31 is fixed to the other end of the connecting rod 31. During the process of sucking external air, the arc-shaped elastic sheet 30 will gradually fit the partition plate 28 under the action of air pressure, and in this process, the arc-shaped elastic sheet 30 will drive the connecting rod 31 and the supporting ball 32 to move until the supporting ball 32 collides with the partition plate 28. At this time, the supporting ball 32 will support the arc-shaped elastic sheet 30 to prevent it from completely blocking the air exchange hole 29, and the vibration generated after the supporting ball 32 collides with the partition plate 28 can further accelerate the sliding of water droplets on the surface of the photovoltaic panel 2, thereby improving the cleaning effect on the surface of the photovoltaic panel 2.

[0040] Working principle: in use, first fill the inside of the floating capsule 5 with air, and make the air pressure inside the two floating capsules 5 equal, then put the mounting frame 1 into the water, and use the buoyancy of the floating capsule 5 to support the mounting frame 1, so that the photovoltaic panel 2 can float on the water surface to generate electricity. The mounting frames 1 can be connected to each other through the cables 3, and the combined action of the mounting frames 1 and the filter frame 4 connected by the cables 3 can filter the floating objects on the water surface and purify the water quality. When the angle of the photovoltaic panel 2 needs to be adjusted, adjust the exhaust assembly 8 inside one side of the floating capsule 5 according to the direction of the inclination angle, and discharge the air inside the floating capsule 5 through the exhaust pipe 9 through the exhaust assembly 8, so that the buoyancy of the floating capsule 5 decreases, and the mounting frame 1 will tilt the photovoltaic panel 2, and then the air outside can be sucked into the floating capsule 5 through the intake pipe 7 through the air suction assembly 6 inside the floating capsule 5, so that the mounting frame 1 is reset, and the inclination angle of the photovoltaic panel 2 is adjusted by the buoyancy. Compared with the traditional support components, there are fewer mechanical structures exposed outside, which avoids the corrosion of the exposed mechanical structures and causes the equipment to fail, and the use is more stable.

[0041] A one-way valve 10 is arranged in the exhaust pipe 9, which can effectively prevent water from entering the inside of the floating capsule 5 and causing damage to the equipment inside the floating capsule 5 when the water flow enters the inside of the exhaust pipe 9 due to the large floating of the water surface. When the gas in the floating capsule 5 is discharged through the exhaust pipe 9, the water flow in the exhaust pipe 9 will be lifted to form a water column, and the water column will be sprayed out of the exhaust pipe 9 and fall on the surface of the photovoltaic panel 2, which can clean the surface of the photovoltaic panel 2.

[0042] When actually used, the staff can adjust the magnetic size of the energized electromagnet 15 according to the amount of gas discharged from the inside of the floating capsule 5, so that the force exerted by the energized electromagnet 15 on the adjusting magnet 12 changes, and then the supporting frame 11 compresses or stretches the adjusting spring 13, and then moves, and then drives the one-way valve 10 to slide in the exhaust pipe 9, so as to adjust the position of the one-way valve 10 in the exhaust pipe 9. In this way, the content of the water flow accumulated in the exhaust pipe 9 can be adjusted, so as to prevent the situation that the discharged air pressure is too small to push the water column out. During the sliding of the one-way valve 10, the sealing effect between the one-way valve 10 and the exhaust pipe 9 can be effectively ensured by the sealing rubber ring 16, so as to prevent water leakage.

[0043] When the external water flow drops inside the exhaust pipe 9, it will first flow through the separation net 17, and the setting of the separation net 17 can effectively filter the impurities in the water flow, preventing the exhaust pipe 9 from being blocked inside. When the water column inside the exhaust pipe 9 is discharged through the separation net 17, it will backwash the separation net 17, preventing the separation net 17 from being blocked and affecting the subsequent water inlet effect, and in this process, the separation net 17 will be deformed and shaken to a certain extent, and in the process, the separation net 17 will be knocked by the hollow ball 18 through the elastic sheet 19 to reciprocate the mounting frame 1. The vibration generated by the knocking can accelerate the sliding of the water droplets on the surface of the photovoltaic panel 2, thereby accelerating the cleaning effect on the surface of the photovoltaic panel 2.

[0044] When the water flow inside the exhaust pipe 9 accumulates to a certain extent, the water level gradually rises until the flow guide frame 20 is completely submerged, and in this process, the hollow block 23 will drive the extrusion rod 22 to slide along the limiting rod 21 under the action of buoyancy, until the extrusion rod 22 extrudes the liquid storage bag 24. After the liquid storage bag 24 is extruded, it will deform to spray the cleaning liquid stored inside, and the sprayed cleaning liquid is mixed with water, further improving the cleaning effect on the photovoltaic panel 2. During the process of discharging the water column, the flow of the water flow will simultaneously drive the rotating frame 26 and the rotating blade 27 to rotate around the support rod 25. The rotating blade 27 can promote the mixing effect of the cleaning liquid and water during rotation, further enhancing the cleaning effect.

[0045] When the air suction assembly 6 sucks external air through the air inlet pipe 7, the external air will enter the air inlet pipe 7 through the air exchange hole 29 in the partition plate 28, and the setting of the arc-shaped elastic sheet 30 can effectively guide the water outside to prevent water from entering the air inlet pipe 7. During the process of sucking external air, the arc-shaped elastic sheet 30 will gradually fit with the partition plate 28 under the action of air pressure, and in this process, the arc-shaped elastic sheet 30 will drive the connecting rod 31 and the support ball 32 to move, until the support ball 32 collides with the partition plate 28. At this time, the support ball 32 will support the arc-shaped elastic sheet 30 to prevent it from completely blocking the air exchange hole 29, and at the same time, the vibration generated by the collision of the support ball 32 and the partition plate 28 can further accelerate the sliding of the water droplets on the surface of the photovoltaic panel 2, thereby improving the cleaning effect on the surface of the photovoltaic panel 2.
