An electric sprinkler truck is a specialized vehicle designed to spray water or other liquids for dust suppression, road cleaning, landscaping, and environmental protection, powered primarily by an electric drive system instead of a conventional internal combustion engine. It typically consists of an electric chassis, a liquid tank, pumping and piping systems, a spraying control system, and various safety and monitoring components.The electric drive system usually includes a high‑capacity battery pack, an electric motor, an electric control unit, and an onboard charging interface. Compared with traditional fuel‑powered sprinkler trucks, the electric version significantly reduces exhaust emissions and operating noise, making it suitable for use in densely populated urban areas, residential neighborhoods, parks, campuses, and industrial parks where environmental requirements are strict. Lower vibration and noise also improve operator comfort during long working hours.The water tank is commonly made of corrosion‑resistant steel or composite materials and is designed with internal baffles to reduce liquid sloshing while the vehicle is moving, improving stability and handling. Tank capacities vary depending on vehicle size and intended application, ranging from small urban models to large units used on wide roads or in industrial sites. The tank is usually equipped with level sensors to monitor remaining liquid volume, which can be displayed in the cab.The pumping system is driven by an electric motor, either drawing power directly from the main traction battery or from an auxiliary power system. A centrifugal pump or gear pump pressurizes the water, distributing it through a network of pipes to front, side, and rear spray nozzles. Many trucks feature adjustable water pressure and flow rates, enabling operators to switch between fine mist for dust suppression and heavier flow for road washing. Nozzles can be configured for fan‑shaped, columnar, or atomized sprays, depending on the task.Control systems are usually centralized in the cab, where the driver can operate valves, select spray patterns, adjust pressure, and start or stop the pump through a touchscreen or physical switches. Some models are equipped with rear or side control panels for ground operators, especially when precise spraying is required in construction sites or green areas. Advanced versions may integrate GPS positioning, work‑time recording, and remote diagnostics, allowing fleet managers to monitor battery status, water usage, and operating routes.Safety features include electrical insulation and waterproofing for high‑voltage components, emergency stop switches, overload and short‑circuit protection, and anti‑skid braking systems. Because the vehicle frequently works near pedestrians and other road users, warning lights, reflective markings, backup alarms, and cameras are often installed to enhance visibility and maneuvering safety.Charging methods typically include AC slow charging at depots and, in some cases, DC fast charging to shorten downtime between shifts. Proper energy management software helps balance driving range and operating time for the pump system, ensuring the truck can complete routine tasks on a single charge.Overall, the electric sprinkler truck combines the functions of traditional road‑cleaning and watering vehicles with the advantages of new energy technology, supporting cleaner cities, reduced operating costs over the vehicle’s life cycle, and compliance with increasingly strict environmental regulations.
