[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides a technical solution to address the existing problems mentioned in the background art.

[0029] Combined with appendix Figure 1 , 2 It can be seen that the tracked mobile base 1 is characterized by: a cleaning mechanism 2 on the top of the tracked mobile base 1, an adjustment mechanism 3 between the cleaning mechanism 2 and the tracked mobile base 1, a water tank 4 fixed on the upper side of the tracked mobile base 1 near the limiting frame 35, a pump 5 on the side of the water tank 4, the input end of the pump 5 connected to the water tank 4, and the output end of the pump 5 connected to the water supply pipe 25, so as to deliver the water in the water tank 4 to several spray heads 23 for spray cleaning; the tracked mobile base 1 is equipped with a battery, which is a common battery on the market, to provide power for the motor 22, electric push rod 31, electric telescopic rod 32, pump 5 and tracked mobile base 1;

[0030] Combined with appendix Figure 2 , 56. It can be seen that the cleaning mechanism 2 includes a cleaning roller brush 21, a motor 22 is fixed at one end of the cleaning roller brush 21, a number of spray heads 23 are evenly arranged on both sides of the cleaning roller brush 21, a support frame plate 24 is provided above the cleaning roller brush 21, and the two ends of the cleaning roller brush 21 are hinged to the lower side of the support frame plate 24. A limiting hole is opened on the side of the support frame plate 24, and a water supply pipe 25 is connected to one end of the spray head 23 and fixed through the limiting hole to facilitate water supply to the spray head 23.

[0031] Combined with appendix Figure 1-4 It can be seen that the adjustment mechanism 3 includes a pair of electric push rods 31 that drive the cleaning mechanism 2 to move up and down, and an electric telescopic rod 32 that drives the cleaning mechanism 2 to swing. The pair of electric push rods 31 are fixedly installed on the upper side of the tracked mobile base 1. A connecting plate 33 is fixed at the top of the electric push rod 31, and a moving frame 34 is fixed at the lower side of the connecting plate 33. A limiting frame 35 is fixed on the upper side of the tracked mobile base 1 to restrict the movement of the moving frame 34. By setting the moving frame 34 and the limiting frame 35, the stable up and down movement of the connecting plate 33 can be effectively guaranteed. One end of the electric telescopic rod 32 is hinged to the upper side of the support frame plate 24, and the other end of the electric telescopic rod 32 is hinged to a fixing plate 36. The bottom end of the fixing plate 36 is fixedly installed on the upper side of the connecting plate 33. The extension and retraction of the electric telescopic rod 32 can drive the support frame plate 24 to swing. The two electric push rods 31 are electrically connected through a synchronous controller to ensure synchronous extension and retraction, so as to drive the connecting plate 33 to move up and down at the same time.

[0032] The working principle of this application is as follows: The working power of this utility model is provided by the battery inside the tracked mobile base 1, which continuously supplies power to the operation of the motor 22, electric push rod 31, electric telescopic rod 32, pump 5 and tracked mobile base 1.

[0033] During operation, the entire equipment is first moved to the area of ​​the photovoltaic modules to be cleaned by the tracked mobile base 1. Then, the adjustment mechanism 3 is activated: a pair of electric push rods 31 extend and retract synchronously under the control of the synchronous controller, driving the connecting plate 33 at the top to move up and down. At this time, the moving frame 34 on the lower side of the connecting plate 33 slides in a direction within the limiting frame 35 on the upper side of the tracked mobile base 1, ensuring the stable lifting and lowering of the cleaning mechanism 2 until the cleaning roller brush 21 is in contact with the surface of the photovoltaic modules. At the same time, the electric telescopic rod 32, through its extension and retraction, drives the support frame plate 24 hinged to it to swing around the hinge point, thereby adjusting the tilt angle of the cleaning roller brush 21 to adapt to photovoltaic modules with different installation angles.

[0034] During the cleaning operation, the pump 5 is started to draw out the clean water in the water tank 4 and deliver it through the water pipe 25 to several spray heads 23 on both sides of the cleaning roller brush 21. The spray heads 23 spray water evenly to moisten the pollutants on the surface of the photovoltaic module. At the same time, the motor 22 drives the cleaning roller brush 21 to rotate. Through the contact friction between the roller brush and the surface of the module, the pollutants are efficiently removed in conjunction with the sprayed clean water.

[0035] Throughout the cleaning process, the tracked mobile base 1 can move slowly as needed, and combined with the adaptability adjustment of the cleaning mechanism 2 and the synergistic effect of the roller brush and spray, the photovoltaic modules are thoroughly cleaned.

[0036] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
