AI Technical Summary

Technical Problem

Existing photovoltaic cleaning robots have poor adaptability in tilted photovoltaic arrays, and are prone to transmission jamming due to foreign objects getting stuck in dusty or muddy environments, which seriously affects the continuity of cleaning operations.

Method used

It adopts a design that combines wire rope drive with corner wheel guidance and double auxiliary wheel positioning. It is equipped with a tension adjuster and hydraulic cylinder driven clamping assembly. The tension of the wire rope and the fixation of the cleaning frame are adjusted by a damper, and a U-shaped cover is set to protect the cleaning block.

Benefits of technology

It achieves low-maintenance and high-reliability transmission in complex environments, avoiding transmission jamming and cleaning frame detachment, and extending the service life of the cleaning blocks.

Abstract

The application discloses a flat brush type photovoltaic cleaning robot based on steel wire rope transmission and relates to the technical field of robots, which comprises a photovoltaic panel and a driving box arranged on one side of the photovoltaic panel, an auxiliary frame is fixedly connected inside the driving box, a servo motor is installed on one side of the auxiliary frame, a second traction wheel is fixedly connected outside the auxiliary frame through the output end of the servo motor, and a tensioning wheel is arranged at the front end of the auxiliary frame; a cleaning frame of the photovoltaic cleaning robot is installed above the photovoltaic panel. Through the cooperation of the driving assembly and other parts, the combination design of the annular closed steel wire rope transmission + corner wheel guiding + double auxiliary wheel positioning is adopted, all core defects of two mainstream structures of synchronous belt wheel & track, chain transmission & wheel type are accurately avoided, the transmission effect of 'low maintenance, strong environmental adaptation and high long-term reliability' is realized, and therefore the practicability of the device as a whole is further improved.
