[0017] Compared with the prior art, the electric vehicle charging station fire prevention and control device has the following beneficial effects:

[0018] The mobile base allows for real-time monitoring of electric vehicles at the charging station via three sets of monitoring cameras on its top, working in conjunction with a controller. The guide hole at the rear of the mobile base slides onto the guide rod at the rear of the support frame, while the threaded hole at the front of the mobile base is threaded onto the drive screw at the front of the support frame. Adjusting the motor drives the drive screw, allowing the mobile base threaded onto the drive screw to move and adjust, providing excellent adjustability. When the device detects a fire in a charging vehicle at the charging station via the three monitoring cameras and the controller, the mobile base moves to the rear of the burning vehicle. The drive motor rotates the connecting plate, and the connecting shaft at the outer end of the connecting plate slides onto the connecting groove at the outer end of the mobile frame. The guide block at the top of the mobile frame slides onto the guide groove at the outer end of the mobile base, causing the mobile frame to reciprocate left and right. The rack at the bottom of the mobile frame meshes with the gear at the outer end of the rotating base, causing the spray plate slot on the rotating base to reciprocate at different angles. This, combined with the controller controlling the control valve at the top of the fire extinguisher, improves the fire extinguishing range and prevents the fire from spreading. The movable claw design allows for easy sliding installation onto the slide rod at the outer end of the mounting bracket via the sliding hole on the movable claw. The screw hole on the movable claw is threaded onto the adjusting screw at the outer end of the mounting bracket. When the fire extinguisher is installed inside the mounting bracket, rotating the adjusting screw causes the movable claw, threaded onto the adjusting screw, to move inward, engaging with the fixed claw. This facilitates quick disassembly, assembly, maintenance, and replacement of the fire extinguisher, improving the efficiency of the device. Attached Figure Description
