Photovoltaic panels are the most critical component in a photovoltaic system. They consist of many solar cells that convert sunlight into electrical energy. It is very important to clean the photovoltaic panels regularly because dust, leaves, and other dirt can reduce the efficiency of photovoltaic panels. When dust and dirt accumulate on the surface of photovoltaic panels, solar energy cannot fully reach the cells, thus reducing the efficiency of power generation. Therefore, regular cleaning of photovoltaic panels can keep them working efficiently, extend their service life, and save energy costs.

[0024] Further, one side of the moving plate 5 is set as a trapezoidal block, and the trapezoidal block is slidably inserted in the middle of the main frame 1, and the other side of the moving plate 5 is set as a rectangular plate, and racks are provided on both sides of the rectangular plate. Figure 1 and attached Figure 2 As shown, the movable plate 5 can slide smoothly along the middle of the main frame 1 and is not easy to fall off.

[0025] Further, two groups of gears 15 are provided, and the two groups of gears 15 are symmetrically distributed on both sides of the first fixed plate 6. The gears 15 are rotatably arranged between the first fixed plate 6 and the main frame 1 through bearings. The two groups of gears 15 are meshed with the racks at both ends of one side of the moving plate 5. Figure 2 As shown, the movable plate 5 is smoother and better balanced when being lifted or lowered.

[0026] Further, one end of the steel rope 10 passes over the outer surface of the pulley 17 and is fixedly connected to one end of the square plate 11 near the third motor 18. Two groups of steel ropes 10 are provided, and the two groups of steel ropes 10 are symmetrically distributed at both ends of the winding column 9. Figure 1 and attached Figure 3As shown, a more balanced and stronger pulling force is exerted on the square plate 11 , laying a foundation for achieving angle adjustment and fixation of the square plate 11 .

[0030] Working principle: When in use, first connect the mains or optional battery to power the device. This is the existing technology. You can choose the power supply method by yourself, and then adjust the height of the square plate 11 according to the height position of the highest point of the photovoltaic panel. First, start the first motor 7 through the control panel 3. The first motor 7 is the output end of the first motor 7 that drives the gear 15 to rotate. The first fixed plate 6 provides support for it. The movable plate 5 engages and moves up and down along the inside of the main frame 1. The movable plate 5 drives the connecting plate 14 to rise and fall synchronously. The connecting plate 14 drives the square plate 11 to rise and fall synchronously. After the height of the hinged end of the square plate 11 and the connecting plate 14 is consistent with the height of the highest point of the photovoltaic panel, the universal wheel is used to move the square plate 11 up and down. 4 Move the device to the photovoltaic panel, support the device with the support frame 2, and then start the second motor 16 through the control panel 3. The second motor 16 is also a stepping motor with sensitive response and strong controllability. The output end of the second motor 16 drives the winding column 9 to rotate. As the winding column 9 rotates, the steel rope 10 is loosened, the length of the steel rope 10 gradually increases, and the square plate 11 is hinged and rotated under the influence of gravity. When the second motor 16 is turned off, the winding column 9 stops rotating, and the steel rope 10 pulls the square plate 11 so that the inclination angle of the square plate 11 is fixed and will not continue to rotate. This method is continued until the lower surface of the square plate 11 is in contact with the surface of the photovoltaic panel.

[0031] Then, the spray head 20 is connected to the external water delivery device through an external pipe, and water is sprayed out through the spray head 20 through the external water delivery device, and then the third motor 18 is started through the control panel 3. The third motor 18 is a DC brushless motor with stable speed and low noise. The output end of the third motor 18 drives the screw 12 to rotate, and the screw 12 drives the cleaning plate 13 to move along the square plate 11. At the same time, the cleaning plate 13 slides along the outer surface of the limit rod 19, so that the cleaning plate 13 moves more smoothly, and the triangular block at the bottom of the cleaning plate 13 pushes away the wet dust, thereby achieving the cleaning of the photovoltaic panel. The above is the entire working principle of the utility model.

[0032] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
