Description

Technical Field

[0001] This utility model relates to the field of photovoltaic maintenance technology, and in particular to a winter maintenance device for power photovoltaic panels. Background Technology

[0002] Winter maintenance of photovoltaic panels is crucial, especially in cold, snowy, or extreme weather regions. Snow, ice, and low temperatures can affect the performance of photovoltaic panels and even cause physical damage. Therefore, designing an effective winter maintenance device is very important to ensure the stable operation of photovoltaic systems.

[0003] A winter maintenance device for power photovoltaic panels, disclosed in CN218301342U, includes a clamping assembly, a driving assembly, a rotating rod, a mounting rod, and a wiping block. The clamping assembly is used to clamp the mounting frame of the power photovoltaic panel, and the rotating rod is rotatably connected to the clamping assembly. The mounting frame of the power photovoltaic panel can be clamped by a first clamping plate and a second clamping plate. Then, the wiping block is driven by a geared motor to rotate intermittently in both directions, so that the wiping block can clean the surface of the power photovoltaic panel, thereby automatically removing the snow accumulated on the power photovoltaic panel, saving time and effort.

[0004] The aforementioned winter maintenance device for power photovoltaic panels uses the movement of wiping blocks to clean the snow accumulated on the surface of the photovoltaic panels. However, in the low temperatures of winter, there may be freezing rain and snow, which are quite hard and difficult for the wiping blocks to clean, and may also damage the photovoltaic panels. Therefore, a new type of winter maintenance device for power photovoltaic panels is provided to solve the above problems. Utility Model Content

Rotate each set of bolts 51, and the bolts 51 move axially. The top plate 52 moves accordingly to a position closer to or further away from the air guide duct 1, controlling the top plate 52 to cooperate with the air guide duct 1 to clamp at the edge of the photovoltaic panel.
