[0002] Photovoltaic cleaning equipment includes cleaning robots and other devices specifically used for cleaning photovoltaic panels. Photovoltaic panels are usually cleaned by high-pressure water pumps, robotic arm systems, and cleaning devices. The cleaning equipment needs to move on the photovoltaic panel during cleaning, and usually a driving mechanism in the form of a driving wheel, a driven wheel, and a crawler track enables the cleaning device to move and turn on the photovoltaic panel. However, after the driving mechanism has been used for a certain period of time, the crawler or transmission belt tends to loosen, affecting its movement efficiency, and requires tensioning and adjustment. For example, the patent with announcement number CN217835828U discloses a crawler tensioning device and a crawler-type traveling device, which increase the friction between the crawler and the photovoltaic panel through elastic parts and pressure plates. However, the above technical solution can only tension the lower transmission belt, which is likely to cause the upper part to be loose and the lower part to be tight, affecting the walking of the driving mechanism.

The crossbeam 11 also has a guide hole 112 parallel to the adjusting hole 111, the first fixing hole 931 of the limiting plate 93 and the second fixing hole 911 of the sliding block 91 are arranged corresponding to the guide hole 112 and connected by a locking member 94, and the locking member 94 can adopt an existing locking member such as a screw. The sliding block 91 is fixed on the connecting shaft 321, the adjusting member 92 is arranged on the front frame 18 of the photovoltaic mobile cleaning device, and the adjusting member 92 is connected to the sliding block 91. In the above technical solution, a transmission belt 33 is arranged between the driven wheel 32 and the driving wheel 31, and the driving wheel 31 drives the transmission belt 33 and the driven wheel 32 to rotate. After the transmission belt 33 has been used for a period of time, it is easy to loosen, and the transmission belt 33 is tightened by the tensioning device. When tensioning, the locking member 94 is released, so that the limit plate 93, the sliding block 91 and the connecting shaft 321 are in a connected and movable state. The adjusting member 92 is operated, and the sliding block 91 is driven to slide by the adjusting member 92, so that the connecting shaft 321 slides along the adjusting hole 111, so that the driven wheel 32 moves and the transmission belt 33 is tensioned.
