With the large-scale construction of solar photovoltaic power stations, photovoltaic power stations face the problem of component cleanliness. In the past, the cleaning of photovoltaic modules is mostly in a manual cleaning mode, and at present, more and more automatic cleaning robots are used in the cleaning work of the photovoltaic modules. In order to improve the utilization efficiency of the robot, a transport trolley is generally adopted to carry a cleaning robot and transport the cleaning robot to the side of each row of photovoltaic modules for automatic line changing cleaning. In the operation process of the robot system, due to factors such as terrain or weather, the transportation trolley may move accidentally when stopping beside the photovoltaic module, and in order to keep the position state of the transportation trolley in the operation process, the transportation trolley generally needs to have a certain locking function. The common locking modes at present are as follows: the driving wheel is locked through the self-locking function of the driving motor, so that the transport trolley is prevented from moving; or the stop lever and the baffle plate limit the movement of the transport trolley at the stop position.
