Title:
TWISTABLE PHOTOVOLTAIC PANEL CLEANING ROBOT
Document Type and Number:
WIPO Patent Application WO/2023/226057
Kind Code:
A1
Abstract:
Disclosed is a twistable photovoltaic panel cleaning robot, which comprises: two edge walking devices, a cleaning roller, a first motor which drives walking wheel sets, a second motor which drives the cleaning roller, and a battery pack, wherein the two edge walking devices are connected together by means of a connecting shaft and can perform relative rotations, so that the walking wheel sets of the two edge walking devices can walk, at the same time, on two respective surfaces having different inclination angles, and two respective end parts of the cleaning roller are connected to the two edge walking devices by means of universal joints. The two edge walking devices can twist relative to each other, and the cleaning roller can rotate back to continue to clean in a twisted state. Compared to a cleaning robot which has a frame structure, the total weight can be reduced by about 35%, and the deformation amount of a photovoltaic module is greatly reduced.
