[0041] It should be noted that Figure 1 - Figure 6 The structure in the figure is only used as a reference for mechanical transmission and is not a structural proportional diagram of the final product.

[0042] Furthermore, the first limiting ring 204 includes a first slot 204a and a first pulley 204b. The first limiting ring 204 is rotatably connected to the upper end of the fixed platform 101 through a third sleeve. The first slot 204a is opened on the inner side of the first limiting ring 204, and the first pulley 204b is fixedly connected to the circumferential surface of the first limiting ring 204.

[0043] Furthermore, the second limiting ring 205 includes a second slot 205a, a first protrusion 205b and a first hinged rod 205c.

[0044] It should be noted that the first slot 204a and the second slot 205a are opened in opposite directions. When the motor 101a rotates clockwise, the curved surface of the block 203d contacts the curved surface of the first slot 204a, the spring 203c is compressed, the first limit ring 204 does not rotate, and the other block 203d is engaged with the second slot 205a, thereby driving the second limit ring 205 to rotate.

The storage box 208 is connected to the water inlet 207b through a connecting pipe.

[0047] It should be noted that since photovoltaic panels are generally installed at a small angle, clean water will fall from the inclined direction of the photovoltaic panels after cleaning the photovoltaic panels. The spray box 207 connected to the first hinged rod 205c contains detergent, and the spray box 207 connected to the second hinged rod 206b contains clean water. The water tank 208 located at the upper end of the spray box 207 contains detergent and clean water respectively.

[0048] In addition, a first one-way valve is installed in the water outlet 207c, and a second one-way valve is installed in the water inlet 207b. The water outlet 207c is connected to the lotus nozzle through a connecting pipe. When the piston plate 207a moves downward, the first one-way valve is closed and the second one-way valve is opened. The water in the storage tank 208 can flow into the spray box 207 through the water inlet 207b. When the piston plate 207a moves upward, the first one-way valve is opened and the second one-way valve is closed.

At this time, a rolling gear 102a fixedly connected to a section of the cleaning roller 102 is meshed with the rack 101b, which can drive the cleaning roller 102 to rotate continuously during the movement. At this time, the curved surface of the block 203d contacts the curved surface of the first slot 204a, and the spring 203c is compressed, so that the first limiting ring 204 does not rotate, and the other block 203d is engaged with the second slot 205a, thereby driving the second limiting ring 205 to rotate. The second limiting ring is connected to the first hinge The rod 205c drives the piston plate 207a to move, thereby spraying cleaning liquid on the surface of the photovoltaic panel, and cooperates with the rolling of the cleaning roller 102, so that the cleaning efficiency of the cleaning roller 102 on the surface of the photovoltaic panel is better. When the motor 101a reverses, the curved surface of the block 203d contacts the curved surface of the second slot 205a, the spring 203c is compressed, the second limit ring 205 does not rotate, and the addition of cleaning liquid stops. The engagement of the block 203d with the first slot 204a drives the first limit ring 204 to rotate, thereby spraying clean water on the surface of the photovoltaic panel and flushing the cleaning liquid. At this time, cooperate with the rolling reset of the cleaning roller 102 to further clean the surface of the photovoltaic panel, which greatly improves the cleaning efficiency of the surface of the photovoltaic panel and has better practicality.
