Liquid fire extinguishing agent tank car for fire extinguishment

Abstract

The invention discloses a liquid fire extinguishing agent tank car for fire extinguishment. The liquid fire extinguishing agent tank car comprises a drivable car body, and a fire extinguishing agent tank arranged on the car body, wherein a spray pipe for spraying fire extinguishing agent is arranged on the fire extinguishing agent tank; the fire extinguishing agent tank is arranged in a sealed box; and a pressurization machine for supplementing pressure into the fire extinguishing agent tank is arranged outside the fire extinguishing agent tank. As a gas is charged in the fire extinguishing agent tank through the pressurization machine, the sufficient pressure in the fire extinguishing agent tank is guaranteed to spray out the fire extinguishing agent inside, the effective life is largely prolonged, and the use efficiency of the fire extinguishing agent is improved; and the fire extinguishing agent tank is suspended, and a spring support and a hydraulic extension mechanism are used for fitting to realize the shaking of the fire extinguishing agent tank so as to evenly mix the fire extinguishing agent inside, so that the problem of efficacy loss or efficacy reduction due to precipitations caused by long-time preservation of the liquid fire extinguishing agent is prevented.

Description

technical field [0001] The invention relates to a fire extinguishing device in the field of fire fighting equipment, in particular to a liquid fire extinguishing agent tank truck for fire extinguishing. Background technique [0002] Fire-fighting equipment in the prior art generally has a validity period and an expiration date, and the fire-fighting facilities cannot be used after the expiration date, resulting in waste. Even if the expiration date is not reached, there is a pressure gauge inside to show that the pressure will decrease with the loss of time. When the pressure is low, only a small part of a can of fire-fighting chemicals can be used. When the fire-fighting area is large, a small number of spare fire-fighting chemicals Equipment just can't put out a fire, especially fire-fighting trolley, and the material of a gas tank shows according to pressure, and a large part can't be used. Sometimes hundreds of fire extinguishers are needed to extinguish a fire, but...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem that the fire-fighting equipment in the prior art cannot be used or cannot be fully used due to the loss of internal pressure over time, the present invention provides a liquid fire extinguishing agent tank truck for fire extinguishing, which can be injected into the fire extinguishing agent tank Supplement the gas to keep the internal pressure in a normal state, thus greatly improving the service life of the fire fighting equipment and the effective use rate of the internal fire extinguishing agent
