Description

Technical Field

[0001] This utility model relates to the field of emergency rescue equipment technology, and in particular to a water supply and drainage vehicle. Background Technology

[0002] Drainage trucks play a vital role in drainage, flood control, and waterlogging relief. Their drainage pumps typically feature high flow rates and low heads, generally exceeding 1500 m³ / h while maintaining a head of less than 30 m. In contrast, water supply pumps used for long-distance firefighting, to meet the pressure requirements of fire hoses and accommodate the elevation difference between the firefighting location and the pump's location, typically require an operating pressure of at least 1 MPa (equivalent to a 100 m head), with their flow rate primarily limited by drive power. Due to the inherent structural characteristics of the pumps themselves, their flow rate and head ranges cannot simultaneously adapt to both of these different operating scenarios.

[0003] Currently, most water supply and drainage emergency vehicles are based on mother-daughter drainage vehicles with the addition of a vehicle-mounted fire pump. The drainage daughter vehicle is responsible for drainage and emergency operations, while the vehicle-mounted fire pump undertakes long-distance water supply tasks. However, in mountainous and forested areas, due to rugged and narrow roads, poor road conditions, and limited vehicle access, the vehicle-mounted fire pump faces significant difficulties in matching water suction conditions with the working site.
