Novel foam fire truck and foam supplying and conveying device

Abstract

The invention discloses a novel foam fire truck and a foam supplying and conveying device. The foam supplying and conveying device comprises a foam pump, a foam liquid inlet pipeline and a foam liquid outlet pipeline, wherein the foam liquid inlet pipeline communicates with a liquid sucking opening of the foam pump; the foam liquid outlet pipeline communicates with a liquid outlet of the foam pump; the foam liquid inlet pipeline comprises a first foam tank communicating opening and a plurality of foam liquid inlet interfaces; the foam liquid outlet pipeline comprises a second foam tank communicating opening and a plurality of foam liquid outlet interfaces; and valves are separately arranged on each foam liquid inlet interface, each foam liquid outlet interface, the first foam tank communicating opening and the second foam tank communicating opening. According to the novel foam fire truck and the foam supplying and conveying device disclosed by the invention, the own extinguishing property of the foam fire truck is effectively improved, and the joint operational capability of the foam fire truck with an force-structure fire truck is also greatly improved; and the utilization rate and the extinguishing efficiency of stored foam liquid in an accident scene are greatly improved.

Description

technical field [0001] The invention relates to the field of fire fighting equipment, in particular to a novel foam fire truck and a foam supply and delivery device added to the traditional foam fire truck. Background technique [0002] The existing foam fire truck is to add one or more ring pump negative pressure or positive pressure foam proportional mixing devices to the water system of the original vehicle, so that the foam and water form a certain ratio. Generally speaking, the ratio of water to foam liquid Generally not more than 8%, and finally output in the form of foam mixture to achieve the purpose of fire extinguishing. [0003] Since the foam proportional mixing device is basically matched according to the rated flow rate of the original vehicle water pump, especially for the foam fire truck equipped with the existing positive pressure foam proportional mixing device, the chassis power must not only meet the power required by the water pump but also meet the requ...

AI Technical Summary

Problems solved by technology

[0003] Since the foam proportional mixing device is basically matched according to the rated flow rate of the original vehicle water pump, especially for the foam fire truck equipped with the existing positive pressure foam proportional mixing device, the chassis power must not only meet the power required by the water pump but also meet the requirements of the water pump. The power required by the positive pressure foam proportional mixing device, resulting in a generally small flow of foam liquid, which is not enough for external transportation (while the ring pump negative pressure foam proportional mixing device does not have the ability to output foam stock solution externally)

[0004] In many medium and large fires, especially petrochemical fires, a large number of foam fire trucks are needed, but due to the limited space, only a very small number of foam fire trucks can really approach the fire scene for fighting, and a large number of foam fire trucks can only be used in Reinforcement was carried out on the periphery, which led to the embarrassing situation that the front car ran out of foam and the rear car could not deliver the foam solution, which seriously affected the fire fighting
