Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 4 In order to solve the problem that photovoltaic panels are inevitably contaminated by impurities such as dust, bird droppings, and leaves during operation due to long-term exposure to the natural environment, these pollutants will not only affect the light transmittance of the photovoltaic panels and reduce their power generation efficiency, but may also damage the surface of the photovoltaic panels and shorten their service life. The following preferred technical solutions are provided:

[0022] A cleaning device for photovoltaic panels comprises a supporting base plate 1 and a supporting frame 2 installed on the upper end of the supporting base plate 1, the upper end axis of the supporting frame 2 is connected to a mounting frame 3 and a telescopic rod 4, the end axis of the telescopic rod 4 away from the supporting frame 2 is connected to a cleaning assembly 5, the inner wall axis of the supporting frame 2 is connected to a motor 6, the output end of the motor 6 is fixedly connected to a threaded rod 7, the outer wall of the threaded rod 7 is threadedly connected to a movable ring 8, the movable ring 8 is fixedly connected to the mounting frame 3, the mounting frame 3 is used to install photovoltaic panels, and the cleaning assembly 5 is used to clean photovoltaic panels.

[0023] The telescopic rod 4 includes an outer rod body 41 having one end connected to the axis of the support frame 2, and an inner rod body 42 having one end connected to the axis of the cleaning component 5. The end of the inner rod body 42 away from the cleaning component 5 is fixedly connected to a movable block 43, and the movable block 43 is slidably connected to the inner wall of the outer rod body 41. The end of the movable block 43 away from the inner rod body 42 is fixedly connected to a return spring 44, and the end of the return spring 44 away from the movable block 43 is fixedly connected to the bottom plate of the cavity of the outer rod body 41.

[0024] The cleaning assembly 5 includes an outer block 51 and a cleaning block 52 slidably connected to the inner wall of the outer block 51. The top plate axis in the cavity of the outer block 51 is connected to a first inclined rod 53 and a second inclined rod 54. A reset torsion spring 55 is installed at the connection between the first inclined rod 53 and the second inclined rod 54 and the outer block 51. The lower end axis of the second inclined rod 54 is connected to a first slider 56, and the lower end axis of the first inclined rod 53 is connected to a second slider 57. The first slider 56 and the second slider 57 are symmetrically distributed about the center of the cleaning block 52, and the first slider 56 and the second slider 57 are both slidably connected to the upper wall of the cleaning block 52.

[0025] Specifically, as the position of the sun changes, the position of the photovoltaic panel needs to be adjusted in angle. At this time, the motor 6 is driven to drive the threaded rod 7 to rotate, and the movable ring 8 moves on the outer wall of the threaded rod 7 to make the mounting frame 3 shift in angle, thereby achieving the purpose of adjusting the position of the photovoltaic panel. At the same time, the inner rod body 42 will drive the movable block 43 to move on the inner wall of the outer rod body 41, and then through the cooperation of the reset spring 44, the cleaning component 5 is moved relative to the outer wall of the photovoltaic panel, thereby cleaning the impurities on the outer wall of the photovoltaic panel, solving the problem that the photovoltaic panel will inevitably be contaminated by impurities such as dust, bird droppings, leaves, etc. due to long-term exposure to the natural environment during operation. These pollutants will not only affect the light transmittance of the photovoltaic panel and reduce its power generation efficiency, but may also damage the surface of the photovoltaic panel and shorten its service life.

[0026] When cleaning the photovoltaic panel, the cleaning block 52 is compressed to squeeze the first slider 56 and the second slider 57. The first slider 56 and the second slider 57 drive the first inclined rod 53 and the second inclined rod 54 to deflect at an angle, thereby compressing the reset torsion spring 55. At this time, the reset torsion spring 55 is used to give a reaction force to the first inclined rod 53 and the second inclined rod 54, driving the first slider 56 and the second slider 57 to push the cleaning block 52 outward, so that the cleaning block 52 fits tightly against the outer wall of the photovoltaic panel, thereby improving the cleaning efficiency.

[0027] To sum up: drive the motor 6, use the motor 6 to drive the threaded rod 7 to rotate, and through the movement of the movable ring 8 on the outer wall of the threaded rod 7, the mounting frame 3 is angularly offset to achieve the purpose of angular adjustment of the position of the photovoltaic panel. At the same time, the inner rod body 42 will drive the movable block 43 to move on the inner wall of the outer rod body 41, and then through the cooperation of the reset spring 44, the cleaning component 5 is relatively moved on the outer wall of the photovoltaic panel, so as to clean the impurities on the outer wall of the photovoltaic panel. When cleaning the photovoltaic panel, the cleaning block 52 is pressed to squeeze the first slider 56 and the second slider 57, and the first slider 56 and the second slider 57 drive the first oblique rod 53 and the second oblique rod 54 to deflect at an angle, thereby compressing the reset torsion spring 55. At this time, the reset torsion spring 55 is used to give the first oblique rod 53 and the second oblique rod 54 a reaction force, driving the first slider 56 and the second slider 57 to push the cleaning block 52 outward, so that the cleaning block 52 is tightly fitted to the outer wall of the photovoltaic panel, thereby improving the cleaning efficiency.
