Downward locking device used for transport trolley for photovoltaic module cleaning robot

Abstract

The invention discloses a downward locking device used for a transport trolley for a photovoltaic module cleaning robot. Transport rails are arranged on one sides of all rows of photovoltaic modules and are parallel to the edges of the photovoltaic modules. The transport trolley carrying a cleaning trolley travels on the transport rails. A plurality of locking rail frames are arranged on the innersides of the transport rails. Four vehicle-mounted locking devices are mounted on the transport trolley. The downward locking device comprises the vehicle-mounted locking devices and the locking railframes. The downward locking device is reasonable in structure; the longitudinal locking function of the transport trolley is realized through the first locking device, the second locking device, thethird locking device and the fourth locking device which are internally provided with longitudinal lead screws; and the problem that the transport trolley slides in the operating process due to the gravity and other accidents is solved, and the safety of the robot in the operating process is improved.

Description

technical field [0001] The invention relates to the technical field of locking equipment for a photovoltaic module cleaning robot, in particular to a downward locking device for a transport trolley of a photovoltaic module cleaning robot. Background technique [0002] With the large-scale construction of solar photovoltaic power plants, photovoltaic power plants are facing the problem of component cleaning. In the past, the cleaning of photovoltaic modules was mostly manual cleaning. At present, more and more automatic cleaning robots have begun to be used in the cleaning of photovoltaic modules. In order to improve the utilization efficiency of the robot, a transport trolley is usually used to carry the cleaning robot to transport it to each row of photovoltaic modules for automatic line-changing cleaning. During the operation of the robot system, due to factors such as terrain or weather, the transport trolley may move due to accidents when it stops beside the photovoltai...

AI Technical Summary

Problems solved by technology

This locking method needs to keep the motor continuously energized. Once the motor is powered off, the robot will lose the locking function and may move due to accidents, causing danger.

At the same time, the continuous power-on of the motor needs to consume the limited battery power of the robot, which is not conducive to the long-term locking of the robot.
