Description

Superfine dry powder fire extinguishing bomb without initiating explosive device as propelling and releasing power

Technical Field

The utility model relates to a fire control safety field specifically is a superfine dry powder fire extinguishing bomb of no initiating explosive device as propulsion and release power.

Background

The fire hazard is a big killer endangering the safety of human life and property, the modern science and technology and the modern civilization are highly developed, but the fire hazard is still unavoidable, and millions of fire hazards serving as calculation units occur all over the world every year. Therefore, a plurality of fire extinguishing devices and devices suitable for different fire scenes are developed, and the requirements for extinguishing the fire under most scenes can be basically met.

In recent years, in order to solve the worldwide problem of fire suppression in high-rise buildings, people are researching technical methods and means for high-altitude fire extinguishing by using a rotor unmanned aerial vehicle. Wherein, utilize rotor unmanned aerial vehicle to hover outside the building window, launch dry powder fire extinguishing bomb to indoor explosion is one of the most common and efficient mode. However, in the dry powder fire extinguishing bomb in the market, both the propellant and the explosion source adopt the initiating explosive device, and because the initiating explosive device has strict management regulations in the links of production, transportation, storage, use and destruction according to the current national initiating explosive device management laws and regulations, the dry powder fire extinguishing bomb containing the initiating explosive device cannot be widely used in the fire rescue operation. Therefore, the development of the fire extinguishing bomb without initiating explosive devices as propelling and explosion power has very important practical significance for high-rise building fire suppression by utilizing the unmanned aerial vehicle.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a can be used to compressed gas jettison device to gas generant is dry powder release power, is applicable to and utilizes unmanned aerial vehicle to carry out the dry powder fire extinguishing bomb that high-rise building put out a fire.

The utility model adopts the technical proposal that: an ultrafine dry powder fire extinguishing bomb without initiating explosive device as propelling and releasing power comprises a bomb body and a tail wing which are connected; the inside of the bomb body is divided into a front part and a rear part, wherein the front part is filled with superfine dry powder for fire extinguishing, and the rear end is filled with a gas generating agent packaged by soft cloth; a group of metal film seals are required to be arranged on the projectile body close to the circular end socket of the projectile body at the front end, the metal film seals are uniformly and symmetrically arranged along the outer wall at the axial line position, the number of the openings is 2, 4 or 6, the openings are circular, and the diameters of the openings are consistent; and an electric initiator is arranged in the gas generating agent bag and used for exciting the gas generating agent after receiving a wireless signal, and when the pressure in the bomb body exceeds the pressure resistance value of the metal film seal after the gas generating agent is excited, the superfine dry powder is sprayed out from the metal film seal under the action of high-pressure gas.

Furthermore, the elastomer is designed according to the relevant national technical standard of pressure bottles, and the pressure resistance value of the metal film seal is not less than 1.2 MPa.

Furthermore, the tail wing can adopt a folding mode, including a transverse folding mode or a longitudinal folding mode.

The utility model has the advantages that: the utility model discloses be suitable for compressed gas mode of jettisoninging, dry powder release power adopts gas generating agent, can avoid the management and control measure of existing national initiating explosive device in production, transportation, storage, use, destruction, makes it become a fire extinguishing technology means that can extensively produce, use. And simultaneously, the utility model discloses, in throwing to the building in proper order through many pieces of devices that throw of unmanned aerial vehicle compressed gas, arouse gaseous propellant after receiving wireless signal simultaneously, many pieces of dry powder extinguishing bomb release the superfine dry powder of putting simultaneously, improvement interior space fire extinguishing efficiency that can furthest.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1 and 2, an ultra-fine dry powder fire extinguishing bomb without initiating explosive device as propelling and releasing power comprises a cylindrical bomb body and a tail fin 3 which are connected in sequence; the head of the projectile body is circular, the interior of the projectile body is divided into a front part and a rear part, wherein the front part is filled with fire extinguishing agent 1, and the occupied volume is larger; the rear end of the projectile is fitted with a gas generant package 2, the gas generant package 2 including a gas generant 6 located on the projectile and on the inside. A group of metal film seals are required to be arranged on the projectile body close to the circular end socket of the projectile body at the front end, the metal film seals are uniformly and symmetrically arranged along the outer wall at the axial line position, the number of the openings is 2, 4, 6 or other even numbers, the openings are circular, the diameters of the openings are consistent, and the purpose is to ensure that the stress of the projectile body is basically consistent in one direction and mutually offset in the dry powder releasing process. In order to ensure that the metal film seal 5 is not damaged in a normal state, the elastomer is designed according to the related national technical standard of the pressure bottle, so that the pressure resistance value of the metal film seal is not less than 1.2 MPa.

When a fire disaster occurs, the fire extinguishing bomb is thrown into a high-rise building room through the compressed gas throwing device, the gas generating agent 6 in the bomb body is remotely controlled through the electric initiator 4 to excite reaction, and the generated high-pressure gas carries dry powder to break through the metal film at the sealing position to spray out the bomb body, so that the purpose of extinguishing the fire is achieved.

The tail wing 3 in the utility model adopts a foldable design, and when the launching barrel is put into the launching barrel to wait for launching, the tail wing 3 is in a folded state; after the fire extinguishing bomb is triggered to pop up, the tail wing can be unfolded by adopting elasticity or other modes, so that the aim of stabilizing the flight balance of the fire extinguishing bomb is fulfilled.
