Description

TECHNICAL FIELD

[0001] The present application belongs to the field of cleaning equipment, and particularly relates to a self-adaptive sweeper. BACKGROUND

[0002] When the photovoltaic panels are cleaned in the photovoltaic base station, the photovoltaic panels are spliced between each other, and when the sweeper moves to clean the joint between two photovoltaic panels, the photovoltaic panel on which the sweeper is located will sink under the weight of the sweeper itself, so that the joint between the two photovoltaic panels will be misaligned, and when the sweeper turns around or changes direction, one side of the cleaning roller on the sweeper is likely to move to the surface of the photovoltaic panel located at a high position, so that the sweeper is inclined, the walking mechanism part on the sweeper is separated from the photovoltaic panel, the combination of the sweeper and the photovoltaic panel is poor, and the sweeper will stay in the original position and idle, or slide down from the photovoltaic panel, or the cleaning effect is poor.

[0009] Further, the cleaning member comprises a shell and a cleaning roller rotatably connected in the shell, a connecting hole is formed on the shell, and a wear-resistant sleeve matched with the rotating shaft is mounted on the connecting hole.

[0010] By adopting the above technical scheme, the wear-resistant sleeve can avoid direct contact between the rotating shaft and the shell made of metal, avoid hard contact between metals, and reduce wear and tear.

[0011] Further, a positioning block is arranged on one side of the vehicle body close to the cleaning member, a positioning frame is arranged on one side of the cleaning member close to the vehicle body, the positioning block is located in the positioning frame, and a gap is arranged between the inner wall of the positioning frame and the outer wall of the positioning block.

[0012] By adopting the above technical scheme, the positioning block and the positioning frame can limit the swing range of the cleaning member, so that the edge of the cleaning member does not contact the surface of the photovoltaic panel and is not damaged.

[0013] Further, positioning bolts are threadedly connected to both sides of the rotating shaft on the positioning frame, and the axis of the positioning bolt is perpendicular to the upper end of the positioning block.

[0014] By adopting the above technical scheme, the swing range of the cleaning member can be further adjusted, and the swing range of the cleaning member can be further adjusted by adjusting the two positioning bolts on the positioning frame.

[0015] Further, the outer wall of the positioning block or the inner wall of the positioning frame is provided with an elastic member.

[0016] By adopting the above technical scheme, hard collision between the positioning block and the positioning frame can be avoided when the cleaning member swings, and vibration and noise during equipment operation can be reduced.

[0017] Further, the corner of the positioning block is arc-shaped.

[0018] By adopting the above technical scheme, the contact position of the positioning block and the positioning frame is arc-shaped, so that the edges of the positioning block do not collide with the positioning frame and are not damaged.
