Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel cleaning, and particularly relates to a cleaning device. Background Art

[0002] At present, the photovoltaic modules used for photovoltaic power generation are usually installed outdoors. The photovoltaic panels will be covered by dust and sand, etc., which will greatly reduce the power generation efficiency. Therefore, it is necessary to regularly clean the photovoltaic panels to ensure the power generation efficiency and increase the total power generation.

[0003] A solar photovoltaic panel cleaning device is disclosed in the prior art. As Figure 1 shown, it includes: guide rails 02 arranged on both sides of the solar photovoltaic panel 01 and a support frame 03 arranged outside the guide rails 02. Grooves are symmetrically arranged on both sides of the support frame 03. Two drive shafts 04 are arranged between the support frames 03. Sliders 05 are arranged on the drive shafts 04. A first drive mechanism 06 is fixed above the sliders 05. The first drive mechanism 06 drives the drive shafts 04 to rotate, so that the sliders 05 move horizontally on the solar photovoltaic panel 01. A second drive mechanism 07 and positioning wheels 08 are arranged in the grooves on both sides of the support frame 03. The second drive mechanism 07 drives the positioning wheels 08 to rotate, so that the support frame 03 can move longitudinally outside the guide rails 02. A cleaning brush roller 09 is arranged below the sliders 05 to clean the solar photovoltaic panel 01.

[0004] By setting the cleaning device to a structure that can move horizontally and longitudinally, the solar photovoltaic panel 01 can be comprehensively cleaned. However, the support of the cleaning device on the solar photovoltaic panel 01 all comes from the clamping of the positioning wheels 08 and the guide rails 02. If the size of the cleaning device does not exactly match the size of the solar photovoltaic panel 01, it may cause the positioning wheels 08 to slide out of the guide rails 02, and then the cleaning brush roller 09 at the bottom of the slider 05 will be attached to the surface of the solar photovoltaic panel 01, unable to perform the cleaning work, thus affecting the work efficiency.
