[0017] In order to make the technical solution and beneficial effects of the present invention more clearly understood, the present invention will be further described in detail below with reference to specific embodiments.

[0018] Reference Figure 1 and Figure 2 The present invention discloses a pure electric road maintenance vehicle capable of high-altitude operations, comprising a pure electric vehicle 2 and a waterway device 1. A lifting device 3 and a box assembly 4 are sequentially provided on the rear side of the cab of the pure electric vehicle 2. The waterway device 1 is arranged on the front side of the cab of the pure electric vehicle 2, on the lifting device 3 and the box assembly 4. The box assembly 4 includes a power compartment 41, a tool compartment 42, and a clean water tank 43. The waterway device 1 includes a front water spray rack assembly 11, a high-pressure reel 12, and a high-pressure water pump 13. The front water spray frame assembly 11 and the high-pressure reel 12 are both connected to the output end of the high-pressure water pump 13 through a hose, and the inlet end of the high-pressure water pump 13 is connected to the clean water tank 43. The front water spray frame assembly 11 is arranged in front of the cab of the pure electric vehicle 2, and the high-pressure reel 12 is arranged on the lifting device 3. A high-pressure water gun 15 is provided at the output end of the high-pressure reel 12, and the high-pressure water pump 13 is arranged in the power compartment 41. A rolling door assembly 44 is provided on the power compartment 41, and a drive motor 14 is provided on one side of the high-pressure water pump 13.

[0019] Reference Figure 3 The lifting device 3 includes a mounting base 32 and a platform 35. A lifting arm assembly 33 is mounted on the mounting base 32, and an electric push rod 34 is mounted on the lifting arm assembly 33. The mounting base 32 is fixed to the electric vehicle 2 via saddle bolts 31. A guardrail 36 is mounted on the platform 35. The lifting device 3 is a multi-stage scissor-type lifting mechanism. Guide rails are provided above the mounting base 32 and below the platform 35. When the lifting device 3 is lifted by the electric push rod 34, the connected pin moves within the guide rail. When the lifting device 3 is lowered, the movable pin returns to its original position.

[0020] When performing road cleaning operations, the vehicle's lifting device 3 does not perform lifting operations. Instead, the driver only needs to control the start button on the display panel and select the desired cleaning operation mode. The electronic control system will then control the clean water in the clean water tank 43 to spray a high-pressure water jet through the water channel device 1 onto the operating road surface, cleaning the oil, dust, etc. on the road surface. Driven by the drive motor 14, the high-pressure water pump 13 operates, drawing clean water from the clean water tank 43 into the high-pressure water pump 13, pumping high-pressure water into the second reel 15, passing through the pressure regulating valve, and then entering the electrically controlled combined ball valve controlled by the electronic control system. According to the selected operation mode, the high-pressure water jet flows through the terminal device of the water channel device 1.

[0021] When the spray rod cleaning mode is selected, the spray rod in the front water spray frame assembly 11 located at the front end of the cab performs front water spraying operations; when the reel mode is selected, the high-pressure reel 12 and the high-pressure water gun 15 are connected through a quick-connect connector to perform high-pressure cleaning operations.

[0022] When the driver wants to clean the top of a bus stop sign on the road, or a roadside billboard that needs to be cleaned from above, he only needs to stop the car at the roadside, then go up to the platform 35 via the escalator, pull out the quick-connect connector on the high-pressure reel 12 on the platform 35 and connect it to the high-pressure water gun 15. The high-pressure reel 12 is a retractable reel with both ends automatically retractable. This allows both ends of the high-pressure reel 12 to be automatically retracted. The driver activates the lifting operation button of the electronic control system, and the lifting device 3 performs the lifting operation under the action of the electric push rod 34. When it rises to the designated position, the lifting stops. After pressing the water gun operation handle, a high-pressure water jet will be ejected from the nozzle of the high-pressure water gun.

[0023] It should be understood that the specific embodiments described herein are only used to understand the present invention and are not used to limit the present invention. All other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of the present invention.
