Composite fire extinguishing bomb capable of spraying fire extinguishing agent simultaneously

Abstract

A composite fire extinguishing bomb capable of spraying a fire extinguishing agent simultaneously comprises: a first containing cavity used for containing a dry powder fire extinguishing agent; a second containing cavity used for accommodating a water-based fire extinguishing agent, and the second containing cavity and the first containing cavity are isolated from each other; a control mechanism that is connected with the first containing cavity and the second containing cavity and controls the first containing cavity and the second containing cavity to be opened at the same time so as to spray the dry powder fire extinguishing agent and the water-based fire extinguishing agent to a fire source at the same time. The dry powder fire extinguishing agent and the water-based fire extinguishingagent are sprayed to the fire source at the same time, the dry powder fire extinguishing agent and the water-based fire extinguishing agent can assist each other to extinguish the fire source and effectively prevent re-combustion of the fire source, and therefore the problems that an existing fire extinguishing bomb is poor in fire extinguishing capacity and cannot meet the high fire extinguishing requirements are solved.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing bombs, in particular to a composite fire extinguishing bomb that simultaneously sprays fire extinguishing agents. Background technique [0002] With the development of my country's economy, the requirements for fire fighting are getting higher and higher. In particular, the scope and capacity of transmission lines are increasing rapidly. An important link in transmission lines is the high-voltage substation. The main characteristics of high-voltage substations are high voltage and full of oily substances inside. High voltage, difficult to access by common means of fire fighting. The fire extinguishing bombs that have been announced at present are difficult to meet the fire extinguishing requirements. [0003] The prior art, such as the patent document with publication number CN104353205A, discloses a fire extinguishing bomb with fire extinguishing function, including a bomb body and a...
