Description

Technical Field

[0001] This application relates to the technical field of photovoltaic panels, and in particular to a dust removal device for the surface of new energy photovoltaic panels. Background Technology

[0002] A photovoltaic (PV) panel, also known as a solar panel or solar photovoltaic panel, is a device that converts sunlight into electrical energy. They consist of multiple solar cells, typically made of semiconductor materials. When sunlight shines on a PV panel, photons excite electrons in the semiconductor material, causing them to be released from atoms and forming an electric current. This current can be collected and used to power the device or stored in the battery.

[0003] A search revealed that Chinese patent CN211217649U discloses a cleaning device for new energy photovoltaic panels. The device has the advantages of small footprint, not affecting the installation area of ​​photovoltaic panels, and the ability to perform flexible dust removal without easily damaging the surface of the photovoltaic panels. It solves to some extent the problems of existing cleaning devices for new energy photovoltaic panels that occupy too much space, affecting the installation area of ​​photovoltaic panels, and that do not adopt flexible dust removal methods, which easily lead to damage to the surface of photovoltaic panels.

[0004] Regarding the aforementioned related technologies, the inventors discovered the following drawbacks: During cleaning, it is difficult to automatically spray cleaning fluid; when photovoltaic panels are left unattended for extended periods, their surfaces may become contaminated with bird droppings, leaves, and other dirt. Simply brushing to remove dust is insufficient to clean the surface of the photovoltaic panels, especially bird droppings, which reduces the light transmittance of the solar panels and thus lowers their power generation efficiency. In view of these shortcomings, this utility model is proposed. Utility Model Content

Detailed Implementation

[0021] The following is in conjunction with the appendix Figure 1 —4. This application will be described in further detail.

[0022] This application discloses a dust removal device for the surface of a new energy photovoltaic panel.

[0023] like Figure 1 As shown, a dust removal device for the surface of a new energy photovoltaic panel includes a photovoltaic panel 1, and a linkage mechanism 2 is provided on the top of the photovoltaic panel 1. The linkage mechanism 2 includes a squeezing plate 27 for squeezing and cleaning.

[0024] Please see Figure 3 The linkage mechanism 2 includes an installation block 21 installed on the top of the photovoltaic panel 1. A fixing block 22 is fixedly installed on the bottom of the installation block 21. A sliding groove 23 is opened on the bottom of the fixing block 22. A sliding column 24 is slidably connected inside the sliding groove 23. A cleaning box 25 is fixedly installed on the top of the installation block 21. Multiple springs 28 are fixedly connected to the inner bottom wall of the cleaning box 25. A squeezing plate 27 is fixedly connected to the other end of the multiple springs 28. When the moving plate 47 descends, the sliding column 24 is released. Under the tension of the springs 28, the squeezing plate 27 seals the overflow port 29, avoiding the waste of cleaning agent caused by the opening time being too long, effectively saving cleaning agent and avoiding multiple manual additions.

[0025] Please see Figure 3 The inner wall of the cleaning box 25 is provided with grooves 26 on both sides. One side of one of the grooves 26 is provided with an overflow port 29. The squeezing plate 27 is slidably connected to the groove 26 and the squeezing plate 27 is in contact with the overflow port 29. The moving plate 47 hits the sliding column 24, causing the sliding column 24 to lift the squeezing plate 27, thereby driving the squeezing plate 27 to slide inside the groove 26, opening the overflow port 29, and allowing the internal water cleaning liquid to flow to the surface of the photovoltaic panel 1. Together with the scraping plate 48, the photovoltaic panel 1 is cleaned, effectively improving the cleaning effect and efficiency.

[0026] A blower mechanism 3 is provided at the bottom of the photovoltaic panel 1. The blower mechanism 3 includes multiple blowers 36 for blowing air.

[0027] Please see Figure 2 The blower mechanism 3 includes a connecting block 31 fixedly installed at the bottom of the photovoltaic panel 1. A motor slot 32 is provided inside the connecting block 31. A fan frame 37 is fixedly installed on the inner wall of the motor slot 32. Multiple exhaust fans 33 are fixedly installed on the outer side of the fan frame 37. Multiple air inlet slots 34 are provided at the bottom of the connecting block 31. The air inlet slots 34 are connected to the motor slot 32.

[0028] Please see Figure 2A spray box 35 is fixedly installed on the top of the connecting block 31, and multiple spray nozzles 36 are fixedly installed on one side of the spray box 35. The spray box 35 is connected to the motor slot 32. After cleaning, the external air is drawn in by starting the exhaust fan 33 and enters the interior of the spray box 35 through the motor slot 32. The photovoltaic panel 1 is then sprayed by the multiple spray nozzles 36, achieving a rapid drying effect and preventing dust from adhering to the surface of the photovoltaic panel 1 and causing further contamination.

[0029] A lifting brush mechanism 4 is provided on the rear side of the photovoltaic panel 1. The lifting brush mechanism 4 includes a scraping plate 48 for scraping.

[0030] Please see Figure 4 The lifting and brushing mechanism 4 includes two rectangular plates 41 fixedly installed on one side of the photovoltaic panel 1. A threaded rod 44 is rotatably connected between the two rectangular plates 41. A motor box 42 is fixedly installed on one side of one of the two rectangular plates 41. A motor 43 is fixedly installed on the inner wall of the motor box 42. The output end of the motor 43 is connected to the threaded rod 44. A movable plate 47 is threadedly connected to the outer wall of the threaded rod 44. During cleaning, the motor 43 is started, which drives the threaded rod 44 to rotate, causing the movable plate 47 to move up and down, thereby driving the brushing plate 48 to brush and clean the surface of the photovoltaic panel 1, preventing the photovoltaic panel 1 from accumulating dust and affecting its performance when it is placed for a long time.

[0031] The installed linkage mechanism 2 is used to spray cleaning fluid during cleaning, preventing dirt from adhering to the photovoltaic panel 1 and making brushing difficult, effectively saving manpower. The installed blower mechanism 3 is used to air dry after cleaning, preventing dust from adhering to the surface of the photovoltaic panel 1 and causing re-contamination of the photovoltaic panel 1. The installed lifting brush mechanism 4 is used for cleaning.

[0032] Please see Figure 4 A mounting frame 45 is fixedly installed on both sides of the photovoltaic panel 1. Sliding rods 46 are fixedly installed on the upper and lower sides of the inner wall of the mounting frame 45. The sliding rods 46 are slidably connected to the moving plate 47. A scraping plate 48 is fixedly installed on one side of the moving plate 47. The scraping plate 48 is in contact with the surface of the photovoltaic panel 1. The two sliding rods 46 are used to maintain balance when the moving plate 47 is raised or lowered.

[0033] The implementation principle of the dust removal device for the surface of a new energy photovoltaic panel in this application embodiment is as follows: A linkage mechanism 2 is installed to spray cleaning fluid during cleaning, preventing dirt from adhering to the photovoltaic panel 1 and making brushing difficult, effectively saving manpower. A blower mechanism 3 is installed to air dry after cleaning, preventing dust from adhering to the surface of the photovoltaic panel 1 and causing re-contamination. A lifting and brushing mechanism 4 is installed so that when the moving plate 47 descends, the sliding column 24 is released, and under the tension of the spring 28, the squeezing plate 27 blocks the overflow port 29. The moving plate 47 impacts the sliding column 24, causing the sliding column 24 to lift the squeezing plate 27, thereby driving the squeezing plate 27 to slide... The interior of the trough 26 slides, opening the overflow port 29 and allowing the internal water cleaning solution to flow onto the surface of the photovoltaic panel 1. This, combined with the scraping plate 48, cleans the photovoltaic panel 1. After cleaning, the exhaust fan 33 is activated to draw in external air, which enters the air spray box 35 through the motor slot 32. Multiple air nozzles 36 then spray the photovoltaic panel 1, achieving a rapid drying effect. During cleaning, the motor 43 is activated, driving the threaded rod 44 to rotate, causing the moving plate 47 to move up and down. This, in turn, drives the scraping plate 48 to scrape and clean the surface of the photovoltaic panel 1. Two sliding rods 46 are installed to maintain balance when the moving plate 47 is raised and lowered.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
