Description
Technical Field
The utility model relates to a fire extinguishing bomb in the field of fire control, in particular to a filling and bursting fire extinguishing bomb with a recovery device, which is applied to individual soldiers, vehicles and planes.
Background
The height of modern urban high-rise or super high-rise buildings is increasing continuously, and the national general rules of civil building design GB 50352-2005 stipulates: when the building height exceeds 100m, the building is a super high-rise building regardless of the residence and public buildings. According to the new standard of world super high-rise building society, the super high-rise building is more than 300 meters. In case of fire, the building with the height can not meet the requirement only by a fire truck for fire extinguishment. The existing fire fighting truck for domestic fire fighting is mostly a lifting jet fire truck, a climbing platform fire truck and an aerial ladder fire truck, and the effective fire extinguishing height of all equipment is only 70 meters. At present, the lifting height of the highest lifting fire truck in the world, namely the Finland Bolangtao fire truck is 101m, the fire fighting truck can only solve the problem of fire suppression with the height of about 100m, cannot keep up with the lifting of the height of the current building, and cannot meet the requirements of environmental adaptability and quick response.
For the fire extinguishing of the high-rise building, the existing solution is to adopt a rocket launching platform and remotely throw a light and high-safety fire extinguishing bomb without initiating explosive, fire and explosive, namely a charging plug bursting fire extinguishing bomb, to extinguish the fire in the field. The structure of the filling burst fire extinguishing bomb is shown in figure 1 and comprises: the blast cap 1, gland 2, fire extinguishing agent 3, projectile body 4, base 50 and fin subassembly 6. The outer wall of the projectile body 4 is grooved, when the blast cap 1 is blocked when impacting a target, the speed is rapidly reduced, the projectile body 4, the fire extinguishing agent 3 and other parts continue to move forwards under the action of inertial overload, the projectile body 4 is cracked along the grooves under the double actions of axial extrusion force and radial expansion force of the blast cap 1, the fire extinguishing agent 3 is simultaneously compressed axially by the blast cap 1 and the gland 2 and is subjected to the inertial overload action of the projectile body and the base, and radial expansion is sprayed out from the projectile body 4 at high pressure to realize fire extinguishing; the main function of the base 5 is to attach and secure the projectile 4 while providing support for the tail assembly. The blast cap 1 is filled in the internal installation of bullet head portion of putting out a fire, the body 4 cooperates with the 1 conical surface interference location installation of blast cap, and at 1 inner chamber installation gland 2 of blast cap, when the bullet striking target of putting out a fire, the blast cap is the pressure speed reduction in the twinkling of an eye, the bullet of putting out a fire continues to move forward under the effect of inertial force, under the effect of blast cap 1 and 4 conical surfaces of body, blast cap 1 takes place to fill the stopper formula relative displacement with the bullet of putting out a fire, and then produce and fill the stopper effect, 4 inner walls of extrusion body 4 that the conical surface of blast cap 1 lasts, the internal fire extinguishing agent 3 of gland compression body simultaneously, make the bullet fill the stopper burst, jet out the fire.
However, the existing fire extinguishing bomb can cause damage and injury to ground personnel and objects due to the fact that the residual bomb body and the bomb tail fall high after the fire extinguishing bomb is launched. There is therefore a great need for a plug-burst fire extinguishing bomb with a recovery device that can recover the residual projectile and the tail of the bomb.
In view of the above-mentioned current fill stopper that is used for high-rise building to put out a fire and explodes the above-mentioned of fire extinguishing bomb existence not enough, the utility model discloses the people is based on the practical experience and the professional knowledge that are engaged in this type of product design and manufacture richened many years to the application of cooperation theory, actively add research innovation, in order to establish a fill stopper that fills that has recovery unit and explode the fire extinguishing bomb, can launch to explode to burst and put out a fire the back and retrieve and remain the projectile body and the bullet tail at the fire of fire extinguishing bomb, avoid remaining projectile body and bullet tail have high altitude free fall to cause injures by a crashing and damage to ground personnel.
