Vehicle-mounted high-spray multi-agent combined jet fire extinguishing device

Abstract

The invention discloses a vehicle-mounted high-spray multi-agent combined spraying fire extinguishing device. A fire truck is used as a carrier to fix a turntable, and a turntable is installed on the turntable. The front end is provided with a spray gun; the rotating part of the central gyratory has an outer output pipe and an inner output pipe arranged side by side, and the outer output pipe and the inner output pipe are respectively communicated with the spray gun through the pipeline on the boom; The fixed part of the central revolving body has an outer input pipe and an inner input pipe arranged side by side; the fire truck is provided with various fire extinguishing agent storage tanks, and each fire extinguishing agent storage tank is connected to the outer input pipe through a plurality of delivery pipelines. It communicates with the inner input pipe to supply fire extinguishing agent, and multiple control valves are arranged in the multiple delivery pipelines to control the on-off of the pipelines. The invention realizes that one kind of fire extinguishing agent can be sprayed alone, and two or more kinds of fire extinguishing agents can be sprayed in combination at the same time, which meets the needs of different fire types for fire extinguishing tactics.

Description

[0001] Technical field: [0002] The invention relates to a vehicle-mounted high-spray multi-agent combined spray fire extinguishing device. [0003] Background technique: [0004] At present, in high-rise buildings or large-scale petrochemical, coal chemical production and storage facilities and other fires, high-spray fire trucks are generally used to extinguish fires, while traditional high-spray fire trucks can only spray water or a mixture of water and foam. The disadvantages are: First of all, the fire extinguishing method is single, and the fire extinguishing agent is suitable for a narrow range of fire types, making it difficult to deal with different types of fires; secondly, the fire extinguishing agent has an unsatisfactory anti-resurgence effect, and there is often a hidden danger of resurgence after the open fire is extinguished. [0005] Invention content: [0006] In order to overcome the defects of the prior art, the object of the present invention is to provid...
