Description

Technical Field

[0001] This invention belongs to the field of photovoltaic technology, and in particular relates to a dust removal device for the surface of photovoltaic panels. Background Technology

[0002] With the large-scale development of photovoltaic power plants, photovoltaic panels, as the core component of solar power generation systems, are being installed over an increasingly larger area. However, due to long-term exposure to the outdoor environment, dust, sand, and other pollutants easily accumulate on their surfaces, leading to a decrease in light transmittance and a significant reduction in power generation efficiency. Traditional manual dust removal methods can no longer meet the demands of large-scale, automated dust removal. Therefore, a highly efficient and stable dust removal device for photovoltaic panel surfaces is needed to solve these problems.

[0003] (1) Traditional dust removal methods mostly rely on manual sweeping or external motor drive. Manual sweeping is labor-intensive and inefficient, while external motors increase energy consumption and equipment operating costs.

[0004] (2) The dust removal operation and sewage treatment lack integrated design. The sewage generated during cleaning flows at will, which not only pollutes the photovoltaic panel installation environment, but also wastes water resources, which does not meet the requirements of energy conservation and environmental protection. Summary of the Invention

[0005] In response to the above situation and to overcome the shortcomings of the existing technology, this invention provides a dust removal device for photovoltaic panels. This device uses the hydraulic transmission principle of water flow impacting a water wheel to drive the cleaning brush to achieve a composite dust removal motion of rotation and reciprocating movement without the need for an additional drive motor, thereby reducing energy consumption and operating costs. Combined with a sprinkler pipe to evenly spray water to create a humid environment, it reduces dust residue and improves cleanliness. Relying on the gravity guidance of the inclined bottom wall of the sewage tank, it achieves centralized sewage discharge, and simultaneously solves the technical problems of high energy consumption, incomplete dust removal, and sewage pollution and waste of existing devices.

[0006] The technical solution adopted in this invention is as follows: A dust removal device for photovoltaic panel surfaces includes a wastewater tank, a water storage tank fixedly installed on the bottom wall of the wastewater tank, a photovoltaic panel fixedly installed on the top wall of the water storage tank, a rack fixedly connected to the side edge of the photovoltaic panel, a gear slidably connected to the side wall of the rack, and a cleaning brush coaxially fixedly connected to the side wall of the gear. The gear, through meshing with the rack, converts the reciprocating sliding motion of the slider into its own rotational motion, synchronously driving the cleaning brush to rotate. A sprinkler pipe is fixedly connected to the side wall of the photovoltaic panel, a water pump is fixedly installed on the photovoltaic panel, and a rotating drum is rotatably connected to the outlet end of the water pump. The rotating drum is connected to the water storage tank, and a water collection hood is rotatably installed on the outer circumference of the rotating drum. The water collection hood is connected to the sprinkler pipe, and the rotating drum is connected to the gear transmission. A water wheel is fixedly installed on the inner circumference of the rotating drum. The water wheel receives the impact of the water flow and generates rotational power, driving the rotating drum to rotate synchronously. It is the core component of the hydraulic transmission.

[0007] As a preferred technical solution of this invention, a fixed plate is fixedly connected to the side wall of the rack away from the photovoltaic panel. A sliding groove is provided in the fixed plate, and a slider is slidably arranged in the sliding groove. A rotating shaft is fixedly connected to the side wall of the slider. The free end of the rotating shaft is rotatably connected to a gear. The rack and gear mesh with each other, providing guidance for the rotation and movement of the gear, and working together to realize the reciprocating movement of the cleaning brush. The gear and rack mesh with each other. A connecting plate is fixedly provided on the side wall of the photovoltaic panel. The side wall of the connecting plate is fixedly connected to a water spraying pipe. The water spraying pipe receives the water flow delivered by the water collection hood and sprays it evenly onto the surface of the photovoltaic panel through the water spraying holes to form a moist dust removal environment. Water spraying holes are fixedly arranged in a linear array on the circumferential side wall of the water spraying pipe, and the water spraying holes are located directly above the photovoltaic panel.

[0008] As a preferred technical solution of this invention, the end of the slider away from the rotation axis is hinged to a crank, the lower wall of the crank is fixedly connected to a connecting shaft, the bottom wall of the connecting shaft is fixedly connected to the rotating drum, the water collection hood is movably and closely fitted to the rotating drum, and the side wall of the water collection hood is connected to and fixedly connected to the sprinkler pipe.

[0009] As a preferred technical solution of this invention, the circumferential sidewall of the rotating cylinder is provided with a drain outlet, and the rotating cylinder and the water collection cover are connected through the drain outlet.

[0010] As a preferred technical solution of this invention, the suction end of the water pump is connected to a suction pipe that is fixedly connected to it, and the free end of the suction pipe is connected to the inside of the water storage tank.

[0011] As a preferred technical solution of this invention, a drain outlet is provided through the bottom of the side wall of the sewage tank, the bottom wall of the sewage tank is inclined, and the drain outlet is located at the bottom of the slope of the bottom wall of the sewage tank.

[0012] The beneficial effects of the present invention after adopting the above structure are as follows:

[0013] (1) Hydraulic drive is energy-saving and efficient: It utilizes the hydraulic transmission principle of water flow impacting water wheel to drive the rotating drum to rotate. Without the need for an additional drive motor, it can realize the combined dust removal motion of the sweeping brush rotation and reciprocating movement. Technically, it reduces the energy consumption and operating cost of the equipment and solves the technical problems of high energy consumption and high operating cost caused by the reliance on external motors in existing dust removal devices.

[0014] (2) Moisture-assisted cleanliness improvement: The principle of dust removal is to use the water spray pipe to evenly spray and create a moist environment, so that the cleaning brush can operate under moist conditions. Technically, this effectively reduces dust residue and improves the cleanliness of the photovoltaic panel surface, solving the technical problems of incomplete dust removal and insufficient cleanliness in traditional dry dust removal.

[0015] (3) Centralized environmental protection treatment of sewage: By utilizing the gravity guiding principle of the inclined bottom wall of the sewage tank, the sewage generated by cleaning is automatically collected and discharged through the sewage outlet. In terms of technical effect, it realizes the centralized collection and standardized treatment of sewage, and solves the technical problems of the existing dust removal device's arbitrary discharge of sewage, which pollutes the environment and wastes water resources.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0025] like Figures 1-6As shown, a dust removal device for photovoltaic panels includes a wastewater tank 1. A drain outlet 2 is provided through the bottom of the side wall of the wastewater tank 1. The bottom wall of the wastewater tank 1 is inclined, and the drain outlet 2 is located at the bottom of the slope of the bottom wall. A water storage tank 4 is fixedly installed on the inner bottom wall of the wastewater tank 1. A photovoltaic panel 3 is fixedly installed on the top wall of the water storage tank 4. A rack 5 is fixedly connected to the side edge of the photovoltaic panel 3. A fixing plate is fixedly connected to the side wall of the rack 5 away from the photovoltaic panel 3. A sliding groove 7 is provided in the fixing plate. A connecting plate 13 is fixedly provided on the side wall of the photovoltaic panel 3. A water spray pipe 12 is fixedly connected to the side wall of the connecting plate 13. Water spray holes 21 are fixedly opened in a linear array on the circumferential side wall of the water spray pipe 12. The water spray holes 21 are located directly above the photovoltaic panel 3. A slider 8 is slidably provided in the sliding groove 7. A rotating shaft 14 is fixedly connected to the side wall of the slider 8. A gear 6 is rotatably connected to the free end of the rotating shaft 14. The gear 6 meshes with the rack 5. A cleaning brush 10 is coaxially fixedly connected to the side wall of the gear 6.

[0026] A crank 9 is hinged to the end of the slider 8 away from the rotating shaft 14. A connecting shaft 19 is fixedly connected to the lower wall of the crank 9. A rotating cylinder 18 is fixedly connected to the bottom wall of the connecting shaft 19. A water collection cover 16 is rotatably provided on the outer circumference of the rotating cylinder 18. The water collection cover 16 is movably and tightly fitted with the rotating cylinder 18. The side wall of the water collection cover 16 is connected to the sprinkler pipe 12. A water wheel 17 is fixedly provided on the inner circumference of the rotating cylinder 18. A drain outlet 20 is opened on the side wall of the rotating cylinder 18. The rotating cylinder 18 and the water collection cover 16 are connected through the drain outlet 20. A water pump 15 is rotatably connected to the lower end of the rotating cylinder 18. The outlet end of the water pump 15 is connected to the rotating cylinder 18. The suction end of the water pump 15 is connected to the suction pipe 11, and the free end of the suction pipe 11 is connected to the inside of the water storage tank 4.

[0027] In practical use, the water pump 15 is started first. The water in the water tank 4 is driven by the water pump 15 and enters the rotating drum 18 through the suction pipe 11. The water flows from bottom to top and impacts the water wheel 17. Then it is discharged from the drain port 20 on the side wall of the rotating drum 18 and flows into the outer water collection cover 16. During this process, the power generated by the water flow impact drives the water wheel 17 to rotate, which in turn drives the rotating drum 18 to rotate synchronously. The rotating drum 18 drives the crank 9 to rotate through the connecting shaft 19. When the crank 9 rotates, it drives the slider 8, which is hinged to it, to slide back and forth along the slide groove 7 periodically. During the sliding process of the slider 8, the rotating shaft 14 drives the gear 6 to mesh and slide along the rack 5 and rotate synchronously, so that the cleaning brush 10 realizes a compound motion of rotation and reciprocating movement on the surface of the photovoltaic panel 3, and completes the dust removal operation on the surface of the photovoltaic panel 3.

[0028] The water flowing into the water collection hood 16 converges into the water spray pipe 12 along the connecting channel, and then is evenly sprayed onto the surface of the photovoltaic panel 3 through the water spray holes 21 on the water spray pipe 12, providing a moist environment for the cleaning brush 10 to remove dust and improving the dust removal cleanliness. The sewage generated during the cleaning process falls into the sewage tank 1 below under the push of the cleaning brush 10. Since the bottom wall of the sewage tank 1 is inclined, the sewage automatically flows to the lower end of the bottom wall under the action of gravity and is finally discharged through the sewage outlet 2.
