Disclosure of Invention
In order to solve the problem of timely, safe and reliable fire extinguishing in public transport fire, the invention provides an external hanging type fire extinguishing bag scheme, the whole fire extinguishing bag is divided into an upper part and a lower part, corresponding part placing positions and corresponding pipeline systems are dug out in the two parts respectively, a fire detection system and an internal control unit are added externally, the fire extinguishing bags with different numbers can be conveniently and flexibly selected and installed according to the sizes of buses and the fire risks of the buses, the convenient and targeted fire extinguishing scheme arrangement is realized, the fire extinguishing bag is convenient to install, the fire extinguishing agent is convenient to replace, and the application cost is low. Meanwhile, the communication unit is arranged in the fire extinguishing bag, so that automatic detection and judgment can be realized, the fire can be found in time at the initial stage of the fire and can be automatically extinguished, and the fire can be extinguished in a bud state.
The technical scheme adopted by the invention for solving the technical problem is as follows: a dry powder type public transport fire extinguishing bag is characterized in that a high-pressure gas bag storage cavity is dug in the middle of an upper cast aluminum block and a lower cast aluminum block, annular grooves are dug around the cavity, the annular grooves are connected with a dry powder groove through inclined grooves, the dry powder groove is connected with a horn-shaped nozzle, a plastic protective film is covered on the nozzle, and a motor drives a square block which is internally provided with threads and is installed on the nozzle to open a high-pressure gas bag valve through thread transmission to realize opening. The fire extinguishing ladle is provided with a control panel which is embedded into the lower half aluminum block and fixed on the lower cast aluminum block. The control panel is connected with four smoke flame sensors arranged on the periphery of the fire extinguishing bag through signal lines, and meanwhile, the standard interface is used for receiving signals of other fire extinguishing bag sensors, whether a fire disaster occurs or not is judged through comprehensive analysis, and false opening is avoided. Meanwhile, the standard interface can also realize the power supply of the standard interface and the communication with a vehicle control system. And all the sensor and motor connecting wires are drilled at the bottom of the cast aluminum in a wire passing mode. The upper part and the lower part of the fire extinguishing bag are installed through screws, and the fire extinguishing bag is integrally installed in a bus through installation lugs.
When the smoke and flame sensor of the fire extinguishing bag has signals, the control panel can analyze other sensor signals of the fire extinguishing bag and signals of a vehicle control system, when a fire disaster is determined to occur, the motor is controlled to rotate forwards through the motor connecting wire, the square block is pushed to move forwards to compress the valve of the high-pressure air bag, so that high-pressure air enters the annular groove, then the high-pressure air can flow into the dry powder groove along the chute, and the dry powder is blown to break through the plastic protective film and is sprayed out from the nozzle, so that fire extinguishing is realized.

Detailed Description
Specific embodiments of the invention are set forth below and illustrated in the accompanying drawings:
in the figure 1, a high-pressure air bag storage cavity 10 matched with a high-pressure air bag is dug in the middle of a cast aluminum base body 14, an annular groove 11 is dug around the high-pressure air bag storage cavity 10, the annular groove 11 is connected with a dry powder groove 2 through a chute 9, the dry powder groove 2 is connected with a horn-shaped nozzle 3, and a layer of plastic film 4 covers the horn-shaped nozzle 3. The dry powder groove adopts a deeper cubic structure and is mainly used for storing dry powder for fire extinguishment. The fire extinguishing bag is installed in the bus by the installation ear 1. The smoke sensor 6 and the flame sensor 7 are connected to a main control board 13 through signal lines 5, the main control board 13 is connected with a motor 14 through a motor connecting line, the universal interface 12 is used for providing power and transmitting signals for the main control board 13, and the lines and the main control board 13 are installed in a mode of drilling holes and digging rectangular grooves in a cast aluminum substrate 14. The connecting hole 8 is a through hole at the upper block and a threaded hole at the lower block. In the figure 2, a motor 15 shaft is fixed on a cast aluminum base body 14 through threads, threads are arranged in a cuboid 16 and are matched with the threads of the motor 15 shaft, a high-pressure air bag inner valve core 18 locks air in the high-pressure air bag, a cuboid block 16 is matched with a rectangular hole in a high-pressure air bag air nozzle 17, and when the motor 15 rotates, the cuboid block 16 can only move along the axis of the motor.
