DETAILED DESCRIPTION

[0030] Embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] Example 1

[0032] A solar photovoltaic panel cleaning device based on water-saving regulation, such as Figure 1 and Figure 2 As shown, it includes a mounting plate 1, on which two first drive motors 2 are mounted, a cover frame 3 is connected between the output shafts of the two first drive motors 2, and a water outlet 4 is provided on the front right side of the cover frame 3. It also includes: a scraping mechanism 5, which is arranged in the middle of the cover frame 3 and is used to scrape off dust and other impurities accumulated on the solar photovoltaic panel; a spraying mechanism 6, which is arranged on the upper sides of the left and right parts of the cover frame 3 and is used to spray the solar photovoltaic panel after scraping off most of the impurities, so as to facilitate the cleaning of the solar photovoltaic panel.

[0033] It should be noted that a solar photovoltaic panel is a device that converts sunlight energy directly into electrical energy, converting light energy into electrical energy through the photoelectric effect. Photovoltaic panels are in an outdoor environment, and pollutants such as dust, dirt, and bird droppings may block the surface of the photovoltaic panels, reducing the effective illumination area and reducing the power generation efficiency of the photovoltaic panels. Cleaning the photovoltaic panels can ensure their efficient operation, which is beneficial to improving power generation efficiency. The photovoltaic panels are cleaned by using this device, and the mounting plate 1 is installed on the photovoltaic panel. Then the first drive motor 2 is started, and the output shaft of the first drive motor 2 rotates to drive the cover frame 3 to rotate, so that the lower part of the cover frame 3 fits the surface of the photovoltaic panel, and the dust and other impurities accumulated on the photovoltaic panel are scraped off by the scraping mechanism 5. The spraying mechanism 6 sprays the photovoltaic panel after scraping off most of the impurities, which facilitates the cleaning of the photovoltaic panel.

[0034] like Figure 1-Figure 3 As shown, the scraping mechanism 5 includes a second driving motor 51, which is installed on the rear side of the middle part of the cover frame 3, and a first screw rod 52 is connected to the output shaft of the second driving motor 51. The first screw rod 52 is rotatably connected to the cover frame 3, and a movable plate 53 is threadedly connected to the first screw rod 52. A sponge block 54 is connected to the front side of the lower part of the movable plate 53, and a fixed plate 55 is connected between the left and right sides of the inner front part of the cover frame 3.

[0035] like Figure 1 , Figure 2 and Figure 4As shown, the spraying mechanism 6 includes a water storage frame 61, the water storage frame 61 is connected to the upper sides of the left and right parts of the cover frame 3, the filter plate 62 is connected inside the water storage frame 61, the left side of the water storage frame 61 is slidably connected to the cover plate 63, the middle left side of the water storage frame 61 is connected to the outer frame 66, the inner part of the outer frame 66 is installed with a driving motor 64, the output shaft of the driving motor 64 is connected to the second screw rod 65, the second screw rod 65 is threadedly connected to the adjacent cover plate 63, the upper sides of the left and right parts of the cover frame 3 are slidably connected to the water pump 67, a water pipe 68 is connected between the water storage frame 61 and the water pump 67, the water outlet 4 on the front side of the water pump 67 is connected to a nozzle 69, and the nozzle 69 is located above the sponge block 54.

[0036] It should be noted that before cleaning the photovoltaic panel, water is stored in the water storage frame 61, and then the water in the water storage frame 61 is sprayed onto the photovoltaic panel through the water pipe 68 and the nozzle 69 by the water pump 67. When it rains, the drive motor 64 is started, and the output shaft of the drive motor 64 rotates to drive the second screw rod 65 to rotate, thereby driving the cover plate 63 to move downward, so that the water storage frame 61 is no longer in a closed space, which is convenient for rainwater to enter the water storage frame 61, which is beneficial to rainwater collection and can achieve energy-saving and environmental protection effects. The filter plate 62 can filter out large particles of impurities in the rainwater, thereby preventing the water pipe 68 and the water pump 67 from being blocked. When the nozzle 69 sprays water on the photovoltaic panel, the second drive motor 51 is started, and the output shaft of the drive motor rotates to drive the first screw rod 52 to rotate, thereby driving the moving plate 53 moves backward, the movable plate 53 can scrape off most of the impurities on the photovoltaic panel, the nozzle 69 is located at the front side of the movable plate 53, and the nozzle 69 sprays water on the area scraped by the movable plate 53. At the same time, the sponge block 54 cleans the surface of the photovoltaic panel again with water and absorbs the water. When the photovoltaic panel is cleaned, the second drive motor 51 drives the first screw rod 52 and the movable plate 53 to reset forward successively. When reset to the initial position, the fixed plate 55 will be larger than the sponge block 54 to squeeze, thereby squeezing out the sewage, and the sewage will be discharged to the water outlet 4 through the cover frame 3. Most of the impurities are scraped off by the movable plate 53, and then the photovoltaic panel is cleaned twice with the sponge block 54 and water, which can further ensure the cleanliness of the surface of the photovoltaic panel and ensure that its surface is dry, which is beneficial to improving the power generation efficiency.

[0037] Example 2

[0038] On the basis of Example 1, Figure 2 and Figure 5 As shown, it also includes a vibration mechanism 7, which includes a mounting frame 71. The mounting frame 71 is installed on the rear side of the movable plate 53. Three rotating frames 72 are rotatably connected to the mounting frame 71. Torsion springs 73 are connected between the left and right sides of the rotating frame 72 and the mounting frame 71. Cams 74 are rotatably connected to the rotating frames 72.

[0039] It should be noted that impurities on the surface of the photovoltaic panel may clump together, and the movable plate 53 directly scrapes away the agglomerated impurities, which may cause wear on the surface of the photovoltaic panel. When the movable plate 53 moves backward to scrape the surface of the solar photovoltaic panel, it will drive the mounting frame 71, the rotating frame 72 and the cam 74 to move backward successively. When the protrusion on the cam 74 contacts the photovoltaic panel, as the cam 74 moves backward as a whole, it will drive the movable plate 53 to move upward slightly as a whole, thereby avoiding hard contact with the photovoltaic panel during movement, causing wear on its surface.

[0040] like Figure 1 , Figure 2 and Figure 6 As shown, it also includes a support mechanism 8, which includes a guide rod 81. Two left-right symmetrical guide rods 81 are connected to the upper rear side of the cover frame 3, and a support plate 82 is slidably connected between the two adjacent guide rods 81. The rear side of the water pump 67 and the front side of the support plate 82 are connected to magnetic suction parts 83, and the two adjacent magnetic suction parts 83 can be adsorbed.

[0041] It should be noted that when the movable plate 53 moves backward to scrape the surface of the photovoltaic panel, it will drive the water pump 67 to move in the same direction. The water pipe 68 is a soft structure. When the water pump 67 moves backward, it will fall to the lower part, which is not conducive to cleaning the photovoltaic panel. The water pipe 68 can be supported by the support plate 82. When the water pump 67 moves to the left side of the support plate 82, the two adjacent magnetic parts 83 will adsorb each other, thereby driving the support plate 82 to move backward. When the scraping is completed, the water pump 67 will reset forward, driving the support plate 82 to move forward. When the support plate 82 moves forward to the limit state, the limit block on the guide rod 81 will prevent the support plate 82 from moving forward, so that the two adjacent magnetic parts 83 are out of the adsorption state.

[0042] like Figure 1 , Figure 2 and Figure 7 As shown, it also includes a collecting mechanism 9, which includes a water guide frame 92. The water guide frame 92 is installed on the upper left side of the water storage frame 61. The inside of the water guide frame 92 is connected with a baffle 91. The baffle 91 and the adjacent water guide frame 92 form a funnel shape to facilitate the water flow to quickly enter the water storage frame 61.

[0043] It should be noted that when it rains, the cover plate 63 moves downward to leave space for rainwater to enter the water storage frame 61 , and the baffle plate 91 and the adjacent water guide frame 92 form a funnel shape, which facilitates the water flow to quickly enter the water storage frame 61 .

[0044] like Figure 2 and Figure 8As shown, a buffer mechanism 10 is also included. The buffer mechanism 10 includes a contact plate 101. The contact plate 101 is slidably connected to the lower side of the cover frame 3. Four springs 102 are connected between the contact plate 101 and the cover frame 3.

[0045] It should be noted that when the vibration mechanism 7 is in operation, the device will be in a vibrating state, and the spring 102 will have a shock-absorbing and buffering effect on the entire device, thereby enhancing the overall stability of the device.

[0046] The above embodiments are provided for persons familiar with the art to implement or use the present invention. Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
