Abstract
Description
Technical Field
[0001] This utility model relates to the field of dry-hung cleaning robots, and in particular to a walking mechanism for a dry-hung cleaning robot. Background Technology
[0002] A photovoltaic (PV) panel is a power generation device that generates direct current (DC) electricity when exposed to sunlight. PV panels are mainly composed of thin solid photovoltaic cells made of semiconductor materials. PV panels convert light energy into electrical energy through the photoelectric effect. After a certain period of use, PV panels become dirty, requiring cleaning. Therefore, dry-hanging cleaning robots are used.
[0003] Existing dry-hung cleaning robots typically include a main beam, a roller brush, a photovoltaic tracking bracket, photovoltaic modules, and control components. The roller brush rotates at the bottom of the main beam, and a walking mechanism is usually installed on the photovoltaic bracket, so that the photovoltaic tracking bracket can automatically adjust the angle of the photovoltaic panels according to the different angles of sunlight each day.
[0004] However, there will be some error when returning to the original position every evening. After a period of use, the photovoltaic panel will also fluctuate up and down. As a result, when the photovoltaic tracking bracket walking mechanism passes the floating bridge mechanism, one end usually cannot swing left and right, and thus cannot always keep in contact with the photovoltaic panel. Therefore, it is necessary for the photovoltaic tracking bracket walking mechanism on the dry-hanging cleaning robot to swing left and right at one end according to the changes of the photovoltaic panel when passing the floating bridge mechanism, so that the walking wheels can keep in contact with the photovoltaic panel.
