Combined type bus fire extinguishing bag

Abstract

The invention relates to a combined type bus fire extinguishing bag. The fire extinguishing bags achieve unified power supply, communication between the fire extinguishing bags and communication between the fire extinguishing bag and a vehicle and a vehicle remote control system through standard interfaces, when the main control board analyzes various kinds of signals and determines that a fire occurs, the motor drives a inner cylinder core of a liquid mixing cylinder to rotate relative to a outer cylinder wall, so that the inlet of the reactant 1 and the inlet of the reactant 2 are aligned with the connector of each reactant container pipe, the two reaction liquids are mixed in the liquid mixing barrel to generate pressure foam, the pressure foams enter an annular pipeline along the holesin the inner barrel core, when the pressure is larger than the stress limit of the plastic paper film of the outer cover of each flared nozzle at the periphery, the plastic paper film can be broken,foam can be sprayed out along the nozzle, and all-directional fire extinguishing is realized; the remote control system can also assign certain specific fire extinguishing bags to extinguish fire according to video monitoring conditions. The combined type bus fire extinguishing bag has the characteristics that the installation is easy, the internal reaction liquid box can be replaced, the fire behavior can be intelligently and actively analyzed, and the fire extinguishing is realized.

Description

technical field [0001] The patent of the present invention relates to the field of bus fire extinguishing, in particular to a foam type bus fire extinguishing bag. [0002] technical background [0003] At present, bus fire extinguishing mostly adopts the fire extinguishing method equipped with fire extinguishers on board. When a fire occurs, it is often impossible to effectively extinguish the fire at the initial stage due to the chaos on the scene and the lack of fire extinguisher configuration. Although the existing fire extinguishing units shown in the application number 201420558467.3 and the application number 201420423714.9 can be used for bus fire extinguishing, but directly transplanted to the bus, there are problems that the explosives inside may threaten the safety of passengers, cannot be used multiple times, and are unfavorable for installation. Therefore, it is of great significance to design an external fire extinguishing bag that is easy to install, can be use...

Problems solved by technology

[0003] At present, the fire extinguishing method of public transportation is mostly equipped with fire extinguishers on board. When a fire occurs, it is often impossible to effectively extinguish the fire at the initial stage due to the chaos on the scene and the lack of fire extinguishers.

Although the existing fire extinguishing units shown in the application number 201420558467.3 and the application number 201420423714.9 can be used for bus fire extinguishing, but directly transplanted to the bus, there are problems that the explosives inside may threaten the safety of passengers, cannot be used multiple times, and are unfavorable for installation. Therefore, it is of great significance to design an external fire extinguishing package that is easy to install, can be used repeatedly, has an independent detection unit, and can effectively extinguish the fire at the initial stage of the fire, which is of great significance to ensure the safety of passengers in bus fires
