Efficient washing vehicle for railway overhead line system insulator

A water storage tank is installed on the upper end face of a vehicle frame, and the water storage tank supplies water to flushing devices arranged on the tops of a front cab and a rear cab through a water supply system arranged on the vehicle frame; the control module controls the water supply system according to feedback information of the insulator positioning module to enable the flushing device to flush or stop flushing; the top of the water storage tank is provided with a detection device used for detecting the internal water storage amount, the output end of the detection device is connected with the control module, the air braking system is connected with the control module, and the control module controls the air braking system to switch between a heavy parking space braking mode and an empty parking space braking mode according to signals fed back by the detection device. According to the utility model, the overhead line system insulator washing operation can be completed in an unattended operation p
