[0015] Furthermore, it also includes a pumping system for pumping concrete, and the pumping system is arranged at the front or rear of the new energy wet spraying trolley.

[0016] Furthermore, the bracket used to support the drive control module and keep it away from the chassis of the new energy wet spraying trolley is also layered with controllers of the hydraulic system, the water and gas system, and the pumping system.

[0017] The controllers of the hydraulic system, the water-gas system and the pumping system are also arranged on the bracket to prevent the controllers of the hydraulic system, the water-gas system and the pumping system from being damaged when liquid leaks.

[0018] Furthermore, the water-gas system also includes a self-cleaning water tank for providing water for cleaning the new energy wet spraying trolley, and the self-cleaning water tank is arranged on the side of the new energy vehicle chassis where the quick-setting agent water tank is located.

[0019] By setting up a self-cleaning water tank, the new energy wet spraying trolley can be easily cleaned after the operation is completed, which saves time and improves work operation and maintenance efficiency. The self-cleaning water tank and the quick-setting agent water tank are set together to prevent the self-cleaning water tank from leaking and causing water ingress and damage to other equipment.
