Description

Technical Field

[0001] The utility model relates to the field of solar photovoltaic panel equipment, in particular to a device for cleaning solar photovoltaic panels. Background Art

[0002] A solar photovoltaic panel is a device that converts solar energy into electrical energy. It is usually made of silicon materials. The special structure of silicon atoms enables them to release electrons after absorbing photons, thus generating an electric current. The surface of the photovoltaic panel is generally covered with an anti-reflection coating to improve the absorption efficiency of sunlight. Usually, it consists of multiple solar cells, which convert photons in sunlight into electrons through semiconductor materials, thus generating an electric current. The solar photovoltaic panel is installed outdoors. After a long time, there will be a lot of dirt on its surface, resulting in a gradual decline in the conversion rate of solar energy into electrical energy. At this time, the solar photovoltaic panel will be recycled, cleaned, and reused.

[0003] The existing cleaning device uses a high-pressure water gun to spray water flow to remove dirt and dust on the surface of the photovoltaic panel, and then uses a rotating brush head or brush to scrub the surface of the photovoltaic panel to effectively remove stubborn stains. Then, a vacuum cleaner or a dust suction device is used to suck away the sewage and dust after cleaning. It has a certain degree of automation, reduces manual intervention, and improves work efficiency.

[0004] However, in the existing cleaning device, during the transmission process, spraying is carried out synchronously at the bottom of the photovoltaic panel. Usually, a roller transmission device is used for transmission, but there is a lack of a pushing device. When the roller brush frame is lowered during the rolling brush operation, it will be blocked by resistance, and when the roller brush frame is raised, it will not be able to fit the surface of the photovoltaic panel, resulting in poor cleaning. Therefore, a device for cleaning solar photovoltaic panels is proposed to solve the above problems. Summary of the Utility Model

[0037] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0038] Refer to Figures 1 - 6, the utility model provides an embodiment: a device for cleaning solar photovoltaic panels, including a main body 1, a fixed frame 4 is fixedly connected to the top of the main body 1, a limiting groove 23 is opened inside the fixed frame 4, a conveying frame 9 is rotatably connected inside the fixed frame 4, a spray rod 10 is fixedly connected inside the fixed frame 4, a brush cylinder 12 is rotatably connected to the outer wall of the fixed frame 4, a wind knife 13 is fixedly connected inside the fixed frame 4, a motor 21 is fixedly connected inside the fixed frame 4, a transmission belt 22 is fixedly connected to the output end of the motor 21, a push plate 6 is fixedly connected to the outer wall of the transmission belt 22, a sliding column 19 is fixedly connected inside the fixed frame 4, two ends of the bottom spray rod 10 are fixedly connected to connecting blocks 18, the connecting block 18 is slidably connected to the outer wall of the sliding column 19, the sliding column 19 is sleeved with a spring 20, the top of the spring 20 is fixedly connected to the bottom of the connecting block 18, the bottom of the spring 20 is fixedly connected to the top of the main body 1, the outer wall of the connecting block 18 is slidably connected to the inside of the limiting groove 23, and a starting component is provided on the outer wall of the main body 1, and the starting component acts on the device to start.

[0039] Specifically, the motor 21 is started, and the transmission belt 22 is driven to rotate by the motor 21, and then the transmission belt 22 drives the push plate 6 to move, thereby pushing the photovoltaic panel to move, which can ensure that the bottom of the photovoltaic panel is fully sprayed, improve the cleaning effect, and reduce the wear and damage of the equipment, and extend the service life of the equipment. At the same time, when the photovoltaic panel has not yet been sprayed, the bottom and top spray rods 10 will form a tight water wall. When the photovoltaic panel passes, its bottom will apply pressure to the bottom spray rod 10, thereby causing the spray rod 10 to be pressed down. At the same time, this pressure will also drive the connecting block 18 to move, and then the spring 20 will be further compressed through the connecting block 18, increasing the contact area between the bottom of the photovoltaic panel and the spray water flow, making the cleaning more comprehensive and thorough, and because the spray head is made of soft material, it will not cause any scratches to the photovoltaic panel during the entire cleaning process, thereby ensuring that the surface quality and performance of the photovoltaic panel are not affected.

[0040] Reference Figures 1 - 3 and Figure 5 The starting assembly includes a control panel 2 and an electric control device 3. The outer wall of the control panel 2 is fixedly connected to the outer wall of the main body 1, and the outer wall of the electric control device 3 is slidably connected to the inside of the control panel 2.

[0041] Specifically, by controlling the device through the control panel 2 and the electronic control device 3, precise operation of the device can be achieved, ensuring the accurate execution of various functions, providing a convenient operation method, and enabling the operator to easily control the operation of the device.

[0042] Reference Figure 1 and Figure 2 and Figures 5 - 10, an electric box 5 is fixedly connected to the outer wall of the fixing frame 4. A brush roller frame 11 is fixedly connected inside the fixing frame 4. A first sliding column 14 is slidably connected inside the brush roller frame 11. A limiting block 15 is fixedly connected to the outer wall of the first sliding column 14. A first spring 16 is sleeved on the outer wall of the first sliding column 14. The top of the first spring 16 is fixedly connected to the inner wall of the brush roller frame 11. The bottom of the first spring 16 is fixedly connected to a connecting frame 17. The outer wall of the connecting frame 17 is rotatably connected to both ends of the brush barrel 12. A support frame 8 is fixedly connected to the bottom of the main body 1. A water pump 30 is arranged at the bottom of the main body 1. The output end of the water pump 30 is fixedly connected to a first conduit 29. A drain port 24 is opened inside the main body 1. A slope 25 is opened inside the main body 1. A filter bin 28 is fixedly connected to the bottom of the main body 1. A filter plate 27 is slidably connected inside the filter bin 28. A rubber plug 31 is fixedly connected to the outer wall of the filter plate 27. A handle 26 is fixedly connected to the outer wall of the filter plate 27. The outer wall of the filter bin 28 is fixedly connected to one end of the outer wall of the first conduit 29. A wind box 7 is fixedly connected to the bottom of the main body 1. A filter net 34 is fixedly connected to the outer wall of the wind box 7. A fan 32 is fixedly connected inside the filter net 34. One end of the outer wall of the wind box 7 is fixedly connected to a second conduit 33. The other end of the second conduit 33 is fixedly connected to one end of the air knife 13.

[0043] Specifically, since the thicknesses of photovoltaic panels of different specifications are different, when they are being brushed by the roller brush, an upward thrust is formed on the brush barrel 12. Then, the connecting frame 17 is driven to move by the brush barrel 12, and then the first spring 16 is compressed by the connecting frame 17. After the photovoltaic panel is finished being brushed, the brush barrel 12 is driven back to its original position by the rebound of the first spring 16. At the same time, the rebound position is restricted by the limiting block 15 to prevent the brush barrel 12 from falling. The position and pressure of the roller brush can be flexibly adjusted to ensure effective cleaning of photovoltaic panels of various thicknesses, and it can move precisely according to the actual situation of the photovoltaic panel, so that the brush barrel 12 is in full contact with the surface of the photovoltaic panel, thereby better removing dirt and dust. Then, the filtered water source will be transported to the required place through the first conduit 29 under the action of the water pump 30, realizing the recycling of water resources. This recycling method can not only reduce the dependence on external water sources, but also reduce the water consumption cost. At the same time, it also helps to reduce the discharge of waste water, which has a positive significance for environmental protection. During the recycling process, the filter plate 27 will continuously filter the water source to ensure the cleanliness and stability of the water quality. In addition, the design of the slope 25 and the drain outlet 24 can also effectively guide the flow of the water source, improve the drainage efficiency, and reduce the generation of ponding and water stains. This method of treating and recycling the post-spray water source has the advantages of high efficiency, energy conservation, environmental protection, etc., and is a sustainable water resource utilization method. Then, the wind generated by the fan 32 is transported to the inside of the air knife 13 through the second conduit 33 to dry the photovoltaic panel. At the same time, in order to prevent external sundries from being sucked into the fan 32 and causing damage or failure, a filter net 34 is provided at the air inlet of the fan 32, which can reliably isolate external sundries and ensure the normal operation of the fan 32 and the stable operation of the entire drying system.

[0044] Working principle: The device is powered through the electrical box 5, and then the device is controlled through the control panel 2 and the electrical control device 3. The photovoltaic panel is placed on the top of the conveying rack 9, and then the motor 21 is started. The motor 21 drives the fixedly connected conveyor belt 22 to move, and then the conveyor belt 22 drives the fixedly connected push plate 6 to move in a cycle to push the photovoltaic panel. When it reaches the spraying area, the top and bottom spraying rods 10 spray simultaneously. When passing through, the bottom spraying rod 10 is pressed. Then, the spraying rod 10 drives the fixedly connected connecting block 18 to lift inside the limiting groove 23 where it is slidably connected. Then, the connecting block 18 slides on the outer wall of the second sliding column 19 where it is slidably connected, compressing the fixedly connected second sliding column 19, thus completing the double-sided spraying of the photovoltaic panel. Then, when it reaches the rolling brush area, the photovoltaic panel pushes the top brush barrel 12. Then, the brush barrel 12 drives the rotatably connected connecting frame 17 to move. Then, the connecting frame 17 drives the fixedly connected first sliding column 14 to slide inside the rolling brush frame 11 where it is slidably connected, and at the same time compresses the fixedly connected first spring 16, enabling both the upper and lower surfaces to be tightly brushed by the brush barrel 12. After reaching the next link, the first spring 16 rebounds to drive the brush barrel 12 back to its original position. Then, the fan 32 is started, and the wind generated by the fan 32 is transported through the second conduit 33 to the fixedly connected air knife 13 to dry the photovoltaic panel. Then, the spraying water source is concentrated at the drain outlet 24 through the slope 25 and discharged into the filter bin 28, and then filtered through the filter plate 27. Then, the water pump 30 circulates the filtered water source through the first conduit 29. When the cleaning is completed, the fixedly connected filter plate 27 is taken out through the handle 26 for maintenance and cleaning.

[0045] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
