When the cleaning column 3244 moves, it synchronously drives the moving plate 3258 to move horizontally. The moving plate 3258 supports the second motor 3246, which drives the spur gear 3257 to rotate. The spur gear 3257, through meshing with the teeth on the cleaning column 3244, adjusts the vertical up-and-down movement of the cleaning column 3244 within the adjusting column 3241, thereby adjusting the distance between the bottom of the cleaning column 3244 and the photovoltaic panel 1, thus precisely cleaning each part of the photovoltaic panel 1. The moving plate 3258 supports and fixes the limiting module 3247, which limits the lowest descent position of the cleaning column 3244.

[0045] Based on Example 3, such as Figures 1-5 As shown, the limiting module 3247 includes a top plate 32471, which is fixedly mounted on the top of the cleaning column 3244. A limiting frame 32472 is fixedly mounted on the top of the support arm 322 below the top plate 32471. A limiting cavity 32473 is formed in the limiting frame 32472. A buffer member 32474 is inserted in the limiting cavity 32473. A buffer spring 32475 is provided between the bottom of the buffer member 32474 and the bottom of the limiting cavity 32473. A buffer plate 32477 is provided on the top of the buffer member 32474. A second buffer spring 32476 is sleeved on the portion of the buffer member 32474 between the buffer plate 32477 and the limiting frame 32472.

[0046] The working principle and beneficial effects of the above technical solution are as follows: the cleaning column 3244 provides fixed support for the top plate 32471, the moving plate 3258 provides fixed support for the limiting frame 32472, the limiting frame 32472 limits the buffer component 32474, the buffer component 32474 supports the buffer plate 32477, the first buffer spring 32475 buffers the bottom of the limiting frame 32472 and the buffer component 32474, and the second buffer spring 32476 buffers the top of the limiting frame 32472 and the buffer plate 32477. When the cleaning column 3244 descends to the lowest position, the bottom surface of the top plate 32471 abuts against the top surface of the buffer plate 32477, and the buffer plate 32477 buffers and stops the descending cleaning column 32444.

[0047] Example 5

After the photovoltaic power generation panel 1 is cleaned, the jet 3255 on the cleaning column 3244 sprays the photovoltaic power generation panel 1 to accelerate the drying of the photovoltaic power generation panel 1 and prevent excessive cleaning liquid residue from affecting the normal operation of the photovoltaic power generation panel 1.

[0051] Based on Example 5, such as Figures 1-5 As shown, the liquid storage tank 321 is provided with a liquid receiving nozzle 3256 on the side facing the photovoltaic panel 1. The liquid receiving nozzle 3256 is located below the lowest side of the photovoltaic panel 1 and is connected to the liquid receiving chamber 3251.

[0052] The working principle and beneficial effects of the above technical solution are as follows: When cleaning the photovoltaic panel 1, the cleaning liquid flows down along the photovoltaic panel 1 under the action of gravity. The liquid collection nozzle 3256 collects the outflowing cleaning liquid and impurities into the liquid collection chamber 3251, which not only prevents the cleaning liquid from spilling on the ground and track 2 and causing environmental pollution and corrosion to track 2, but also allows the cleaning liquid to be taken back for recycling and reuse, saving costs.
