The conveying pipe 502 is fixedly installed on both sides of the partition frame 501. The conveying pipe 502 is in a U shape. Both ends of the conveying pipe 502 extend to the outside of the bottom of the rainproof frame 5. The plurality of spray heads 503 are fixedly installed on the outer wall of the conveying pipe 502.

Because the charging pile needs to handle large current and voltage, the power board usually uses thick copper plate with more than four layers, and the copper thickness is high to withstand large current and voltage; The power board is used for measuring and charging the electric quantity in the charging process. It is used in cooperation with the control board to ensure the accuracy of charging and the fairness of charging.

[0053] In this example, the converter 602 can use the rectifier in the existing technology to convert alternating current into direct current. The cable on the charging pile is connected with the converter 602, and the charging head is arranged on the cable to charge the new energy automobile.

[0055] The working process and principle of the application: when the fixed charging pile, the electric push rod 101 is started, the extension of the output end of the electric push rod 101 makes the connecting rod 103 push or pull the moving frame 104, so that the moving frame 104 moves in the installation frame 2, the supporting plate 113 rotates out of the rotating groove, the elastic force of the first spring 108 supports the moving block 109 to move downward, thereby driving the fixing part 110 to be clamped in the fixed groove 112 on the top of the installation shaft 111, fixing the angle between the supporting plate 113 and one side of the moving frame 104, at the same time, the motor 305 is started, driving the rotating drum 307 to rotate, and the connecting rope 308 on it is retracted, so that the counterweight 302 falls to the ground.

[0056] It should be noted that in this document, the terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between the entities or operations.
