[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0026] Figure 1-Figure 6 This is a specific embodiment of the utility model, which is a photovoltaic module cleaning device. In order not to damage the waterproofness of the roof, the photovoltaic module counterweight is used as a clamp bracket 20, a first connecting rod support 18, a second connecting rod support 19, and a motor support 17 to support the driving structure of the entire cleaning device.

[0027] The rag integrated device 8 and two built-in submersible pump water tanks 9 are installed in the slots provided on the steel frame 1 of the cleaning equipment through the small hanging ears provided with them. The double-headed motor 5 is started, and the rope reel 4 is driven to rotate through the first connecting rod 6.1 and the second connecting rod 6.2, and the pulling cable 3 is translated. The cable 3 can be adjusted according to the length of each photovoltaic row. The cable buckle connector 2 rigidly connects the cable 3 to the steel frame 1 of the cleaning equipment, driving the translation of the cleaning equipment. The built-in submersible pump water tanks 9 on both sides are each connected to a porous spray pipe 10, which can spray a small amount of water evenly on the photovoltaic components. The stubborn stains on the components can be scrubbed off during the reciprocating process of the cleaning equipment. The porous spray pipe 10 is installed on the bracket 11 on the steel frame 1 of the cleaning equipment.

[0028] In order to avoid the hard contact friction between the cleaning equipment and the photovoltaic module and wear of the photovoltaic panel, the first pulley 13 and the second pulley 14 are added to convert it into rolling friction. The first pulley 13 is installed on the support arm 15. When it is placed on the back of the photovoltaic module during cleaning, it can reduce friction and have a guiding and positioning function. The cylindrical tension spring 12 is used to control the curvature of the support arm 15 so that the first pulley 13 rolls along the module.

[0029] When the rag integrated device 8 needs to be cleaned and replaced, and the built-in submersible pump water tank 9 needs to be filled with water, it can be easily taken out or installed through its own hanging ears, and the installation groove can prevent it from sliding down and play a certain supporting role.

[0030] The lengths of the upper and lower ends of the cleaning equipment steel frame 1 can be appropriately extended to prevent the cleaning equipment from maintaining stable and continuous operation when the gap between photovoltaic modules increases.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
