Median-multiple fire-fighting foam monitor

Abstract

Relating to the field of fire-fighting equipment, the invention provides a median-multiple fire-fighting foam monitor, which mainly solves the defects existing in single-multiple and median-multiple fire-fighting foam monitors. The median-multiple fire-fighting foam monitor includes a connecting pedestal, launch foam barrels and a pipeline barrel frame connecting the connecting pedestal and the launch foam barrels. The connecting pedestal, the pipeline barrel frame and the launch foam barrels are equipped with a mixed solution channel communicated with a mixed foam solution. The launch foam barrels include barrel bodies and nozzles disposed at front ports of the barrel bodies. The foam monitor is characterized in that there exist multiple launch foam barrels, which are fixed on the pipeline barrel frame in a vertical direction and have the same launch direction. Specifically, a low multiple launch foam barrel is positioned below, and launch foam barrels higher than the low multiple launch foam barrel are positioned above. The mixed solution pipeline in the pipeline barrel frame is communicated with the nozzles of all launch foam barrels, and each nozzle is respectively located in the front port of a corresponding barrel body. Compared with traditional low multiple foam extinguishing systems, the fire extinguishing efficiency is improved; compared with traditional high multiple foam extinguishing systems, the launch range is increased.

Description

technical field [0001] The invention relates to a kind of fire-fighting equipment, in particular to a medium-multiple fire-fighting foam cannon. Background technique [0002] The fire-fighting water with a certain pressure is mixed with the foam liquid by the foam proportion mixing device to form a certain proportion of foam mixture, and the air foam is generated by the nozzle to achieve the fire extinguishing effect. Foam fire extinguishing systems are classified according to the expansion ratio: low-expansion foam fire-extinguishing systems with an expansion ratio of less than 20 times; medium-expansion foam fire-extinguishing systems with an expansion ratio of 20 to 200 times; High expansion foam fire extinguishing system. [0003] The low-expansion foam fire extinguishing system is characterized by low foam expansion and low fire extinguishing efficiency, but it has a long range. [0004] The high-expansion foam fire extinguishing system is characterized by high foam e...

Problems solved by technology

But its disadvantages are: Several foam cannons are connected to their respective foam containers through connecting hoses. Except for the linkage in operation, the fire-fighting foam liquid sprayed by the foam cannons has nothing to do with each other. In theory, it still belongs to the foam cannon. Use alone

In addition, in terms of height, it is suspended in the air by lifting equipment to extinguish fires in high-rise buildings, which increases the difficulty of use. Due to the limitations of the range and foaming multiples of fire sources that cannot be approached, it is impossible to efficiently extinguish fire sources at long distances.
