Dry powder type fire extinguishing bag for bus

Abstract

The invention discloses a dry powder type fire extinguishing bag for a bus, and the bag is a fire extinguishing system capable of being independently installed and replaced. A high-pressure air bag storage cavity, an annular groove, a chute, a dry powder groove and a horn-shaped nozzle are dug out in each of an upper cast aluminum block and a lower cast aluminum block to form a high-pressure air bag storage position and a main air passage; and four mounting lugs are arranged on the lower cast aluminum block to fix the fire extinguishing bag on a bus body through bolts. When signals are detected by smoke sensors and flame sensors around, the signals are transmitted to a control panel embedded in the lower cast aluminum block through signal lines; the control panel analyzes whether a fire occurs or not by comparing the signals with signals transmitted by a standard interface; and when it is determined that the fire occurs, the control panel drives a motor to drive a square block to pressdown a high-pressure gas bag valve so that high-pressure gas can enter an annular pipeline, an inclined pipeline, a dry powder cavity and the horn-shaped nozzles formed by the upper cast aluminum block and the lower cast aluminum block and break through plastic films outside the nozzles to spray dry powder into the bus to extinguish fire.

Description

technical field [0001] The patent of the invention relates to the field of bus fire extinguishing, in particular to a dry powder type bus fire extinguishing bag. [0002] technical background [0003] At present, bus fire extinguishing mostly adopts the method of configuring fire extinguishers in the car. When a bus fire occurs, it will often fail to achieve effective fire extinguishing due to the chaos on the scene and the limited number of fire extinguishers equipped. Existing patents such as the fire extinguishing unit given in the application number 201420558467.3 and the application number 201420423714.9, when applied to bus fire extinguishing, due to the presence of explosives in the structure, may threaten the safety of passengers, so a design is designed that is easy to install, easy to maintain, and can extinguish fire independently , the external fire extinguishing package that can effectively extinguish the fire at the initial stage of the fire is of great signific...
