Multi-functional fire-fighting combined injection unit, multi-functional fire-fighting combined device and fire engine

Abstract

The invention discloses a multi-functional fire-fighting combined injection unit which comprises an injector and a mixer (302), wherein the mixer (302) is provided with a main fire-fighting agent inlet, a mixed fire-fighting agent inlet, a mixer gas inlet for receiving compressed air and a mixer outlet communicated with the injector. The multi-functional fire-fighting combined device provided by the invention comprises the multi-functional fire-fighting combined injection unit, wherein the main fire-fighting agent inlet of the mixer is selectively communicated with a dry powder output port for outputting fluidized dry powder or the outlet of a concrete pump; the mixed fire-fighting agent inlet is selectively communicated with a foaming agent box (8) or a concrete addition agent box; and the mixer gas inlet is connected with the corresponding compressed air source. Additionally, the invention also provides a multi-functional fire-fighting engine comprising the multi-functional fire-fighting combined device. According to the invention, the injection of various fire-fighting media, such as a water foaming mixing agent, dry powder, concrete can be realized through the whole set of the multi-functional fire-fighting combined device, and thus the practicability is wide, and the fire-fighting performance is excellent.

Description

technical field [0001] The invention relates to a fire-fighting injection device, in particular to a multifunctional fire-fighting combined spraying unit, which can be used to spray various fire-fighting media such as water-foam mixture, dry powder and concrete. In addition, the present invention also relates to a multifunctional fire fighting combination device and a multifunctional fire fighting vehicle comprising the multifunctional fire fighting combination spray unit. Background technique [0002] In the field of fire protection, a variety of fire extinguishing media are widely used for fire extinguishing, such as water foam mixture (also known as water (foam) by those skilled in the art, which is mainly a mixture of water and foam extinguishing agent), dry powder (i.e. dry powder fire extinguishing agent) )Wait. [0003] Dry powder is a dry and easy-flowing fine powder used for fire extinguishing. When extinguishing a fire, the powder mist sprayed out under the action...

AI Technical Summary

Problems solved by technology

The function of existing multifunctional fire trucks is mainly reflected in the word "extinguishing". For super large fire sites, it is necessary to "control first, then eliminate", that is, first build dikes to block and divert the flow, and then cover the fire to extinguish the fire. This often appears to be functional. Insufficient, it is not possible to divide and contain the fire scene while extinguishing the fire, so as to realize covering fire extinguishing

At the same time, the dry powder and nitrogen storage of this multi-functional fire truck is limited, and it cannot be refilled on site. For a large fire scene, it is often impossible to solve the fire at one time. It needs multiple long-distance round-trip feeding and filling to extinguish the fire, and the operation efficiency is not high.
