Advantages of Pure Electric Special Vehicles:

(1) Zero Emissions. Pure electric vehicles use electric energy and produce no exhaust emissions during operation, causing no environmental pollution.

(2) High energy utilization rate. Studies have shown that the same crude oil, after being roughly refined and sent to a power plant for electricity generation, then charged into batteries and used to drive electric vehicles, has a higher energy utilization efficiency compared to being refined into gasoline and then driving vehicles with gasoline engines.

(3) Simple structure. Because it uses a single electric energy source, it eliminates the need for a fuel tank, engine, transmission, cooling system, and exhaust system. Compared to the internal combustion gasoline engine power system of traditional vehicles, its structure is greatly simplified.

(4) Low noise. During driving, vibration and noise are minimal, making the interior and exterior of the vehicle very quiet.

(5) Wide range of raw materials. The electricity used can be obtained from various primary energy sources such as coal, nuclear energy, and hydropower, alleviating concerns about the depletion of petroleum resources.

(6) Peak shaving and valley filling. For power generation enterprises and power companies, the batteries of electric vehicles can be charged at night using the grid's cheap "valley electricity," which can smooth out the peak and valley differences of the power grid, allowing power generation equipment to be fully utilized day and night, thereby greatly improving economic efficiency.

Introduction to pure electric washing and sweeping vehicle:

● The garbage bin has a rectangular shape, with uniform stress distribution, strong structural performance, and an attractive appearance. The garbage bin is made of stainless steel, which will never rust.

● The working device adopts the layout of "central two-disc sweeping + central wide suction nozzle + built-in high-pressure main spray rod + left and right high-pressure side spray rods."

● Center-mounted dual sweep discs (sweep discs can be controlled independently) + center-mounted wide suction nozzle + built-in high-pressure main spray boom + left and right high-pressure side spray booms (left and right high-pressure side spray nozzles can be controlled independently) structure, achieving road surface washing, sweeping, and dust suction.

● Left and right side spray booms arranged in a V-shape and the suction nozzle with built-in main spray boom featuring gapless high-pressure nozzle water spray arrangement effectively gather all the washed sewage and debris to the suction nozzle, absorbing them into the sewage and debris tank, leaving no dust or water accumulation on the road surface, resulting in excellent road cleaning, sweeping, and sewage recovery effects.

● Fresh water tank and debris tank are arranged separately to maximize effective space utilization, allowing for long continuous operation time. During operation, sewage can be discharged through the sewage discharge device, and fresh water can be added at any time to continue work; the debris tank uses dual hydraulic cylinders for self-dumping unloading, and is equipped with high-flow high-pressure nozzles inside the tank for rapid cleaning of the debris tank.

● The left and right high-pressure side spray booms feature bidirectional automatic obstacle avoidance protection and reset functions, greatly reducing damage to the side spray booms and improving overall vehicle safety during operation.

● The centrally mounted wide suction nozzle features a hydraulic floating function, effectively extending the lifespan of the rubber rollers.

● Equipped with a CAN intelligent control system, integrating electrical, hydraulic, and pneumatic centralized control, allowing the driver to operate various functions from inside the cab.

High Performance and Environmental Protection:

The pure electric washing and sweeping vehicle uses high-pressure water flow and inclined brushes to sweep garbage to the front of the suction cup. Under the negative pressure generated by the fan, airflow in a closed loop sucks the garbage into the garbage box for storage. The entire operation process is based on physical principles, producing no chemical waste or secondary pollution from garbage leakage to the environment. Meanwhile, the rear mist spray effectively reduces the dust concentration in the air, solving the dust pollution problem. The washing and sweeping cleanliness is high. This model is fully functional and can handle operations in different road environments. A single operation achieves a washing and sweeping efficiency of over 98%. Features include fixed-point washing, washing and sweeping, curb cleaning, rear mist spraying, low-pressure washing, and the use of a central suction cup combined with left and right spray rods for cleaning. It can effectively clean dust and garbage on surfaces, joints, curves, and curbs, ensuring a clean environment.
