Portable large flow-rate water supplying equipment applied to fire site

Abstract

The invention discloses portable large flow-rate water supplying equipment applied to a fire site. The equipment comprises water delivery equipment, the water delivery equipment is connected with at least one fire truck through a water delivery main belt and a water dispensing device, wherein the water dispensing device is connected with at least one water delivery branch belt; the water deliveryequipment comprises a large flow-rate submersible pump, an equipment power supply, a pipeline pressurizing pump and a fully automatic connecting valve. The large flow-rate submersible pump comprises aWQ series submersible pump. The pipeline pressurizing pump comprises an SLS series single-stage single-absorbing upright centrifugal pump. The equipment power supply comprises a vehicle-mounted powergeneration unit, a mobile power generator equipment and / or a near-unit three-phase power supply. The equipment has the advantages that the equipment can be carried by a single truck, the operation iseasy, medium or short distant large flow-rate water supplying can be achieved, a water source near the fire site can be efficiently and conveniently delivered to the frontier of the fire site, and the defects of other water delivery equipment are overcome.

Description

technical field [0001] The invention relates to a fire-fighting water supply equipment, in particular to a portable large-flow water supply equipment applied in a fire scene. Background technique [0002] In the long-term fire fighting, mainly rely on the external water source to extinguish the fire. In the initial stage of fire fighting and rescue, the water supply of the fire scene becomes a major problem. The water intake intensity, water intake method and water supply guarantee of the current municipal water source facilities can no longer meet the actual fire water requirements. The existing fire water supply equipment and equipment have heavy water supply tasks, especially in water-scarce areas. This problem is more obvious. In view of such outstanding problems of water supply in fire scenes, it is particularly important to research and explore new methods of water supply in fire scenes, innovate portable large-flow water delivery equipment, improve the water supply ca...

AI Technical Summary

Problems solved by technology

[0004] The remote water supply system in the prior art has complicated operation, consumes a lot of manpower and material resources, requires high maintenance, and is expensive, costing tens of millions. When used in water-scarce areas, there are high requirements for water source and water quality. Due to the many constraints mentioned above, the equipment is not popular

[0005] Other water delivery equipment, such as mobile fire pumps, floating boat pumps and other equipment, generally have the following limitations when taking water: First, the water intake environment is restricted, such as the water intake of the pool is surrounded by fences and buildings, and vehicles and motor pumps cannot be parked close , resulting in blocked water intake; second, due to on-site power outages, backup power failures and other reasons, the pool has water but cannot draw water; third, under the severe cold weather conditions in the north, the reliability of water intake by fire trucks and motor pumps is not high. There are many faults in the joints and the vacuum water diversion of the car pump, and the drain valve of the pump body is easy to freeze, resulting in low reliability of the water intake equipment; Fourth, the size of the motor pump, the floating boat pump and other equipment are large and heavy, and it is difficult to carry the equipment with the car
