Description
Technical field
The present invention relates to fire extinguisher bomb lift-off technology field, it is especially a kind of for be classified coyote hole fire extinguisher bomb transmitting device and
Method.
Background technique
Fire extinguisher bomb is a kind of new special Fire extinguisher, and the fire extinguisher bomb equipment of larger caliber, which is primarily adapted for use in, puts out long distance
From the point of origin that the general staffs such as, skyscraper can not arrive at, has the advantages that easy to use, power is big, it is straight to avoid personnel
Tap into personnel hazard caused by the scene of a fire.The small-sized fire extinguisher bomb that existing some fire extinguisher bombs are predominantly jettisoninged by hand, deficiency
Place is that volume weight is limited, and payload is lower, and then can effectively improve payload using heavy caliber fire extinguisher bomb, and raising is gone out
Fiery efficiency.
However, using traditional heavy caliber emitter, there are a series of problems.Since legacy transmission mode is using single
Coyote hole lights gunpowder and fire extinguisher bomb is pushed to advance, and since chambervolume expands in fire extinguisher bomb motion process, leads to gunpowder gas after bullet
Body pressure is linearly distributed, and bullet bottom pressure is much smaller than transmitting tube breech pressure, and the initial velocity of fire extinguisher bomb depends on bullet bottom pressure, hair
Safety is penetrated depending on breech pressure；Since fire extinguisher bomb quality is larger, need enough explosive payloads that could protect during the launch process
Demonstrate,proving fire extinguisher bomb has certain initial velocity to reach farther distance, however bigger charging quality will lead to thorax base pressure in transmitting tube
Power is excessively high, evil emission security；And reducing explosive payload then and will lead to cannot effectively push fire extinguisher bomb to accelerate, and be unable to reach and set
Meter requires.According to the mode of classification coyote hole, then need to light the indoor gunpowder of second level medicine first, and second level coyote hole and thorax bottom it
Between there are level-one coyote hole, existing some electronic ignition devices need to carry out emitter itself it is biggish change it is non-to realize
Impinging fire, process is complex and reliability is to be improved.
Summary of the invention
The purpose of the present invention is to provide a kind of structures, and the coyote hole that is used to be classified simple, safe and reliable, easy to make is put out a fire
The device and method of bullet transmitting.
The technical solution for realizing the aim of the invention is as follows: a kind of device emitted for being classified coyote hole fire extinguisher bomb, including
It is successively set on common igniter in transmitting tube, laser ignition tool, level-one coyote hole, piston, second level coyote hole and fire extinguisher bomb；It is described
Biography fire tool is provided in second level coyote hole；The optical fiber axially extending along transmitting tube, described optical fiber one end are provided in level-one coyote hole
Have with laser ignition and connect, the other end passes through piston and passes fire tool and connects；Hair is provided in the level-one coyote hole and second level coyote hole
Penetrate medicine；Ring holder is set along transmitting inside pipe wall in the level-one coyote hole, support frame is for intercepting piston to level-one coyote hole
Direction it is mobile.
Further, it is rigidly connected between the biography fire tool and piston, does not separate during the motion.
Further, the through-hole that a diameter and fibre external diameters match is provided in the piston, optical fiber is worn along through-hole
It crosses piston and passes fire tool and connect.
Further, the circumferential direction of the piston is provided with annular groove, is equipped with sealing ring in annular groove.
A method of for being classified the transmitting of coyote hole fire extinguisher bomb, comprising the following steps:
Set gradually in step 1, transmitting tube common igniter, laser ignition tool, level-one coyote hole, piston, second level coyote hole and
Fire extinguisher bomb, and use packing mode arming；
Step 2 lights the gunpowder passed in fire tool using laser ignition tool by optical fiber, and powder gases are passed fire tool and light two
The grade indoor propellant powder of medicine；
Step 3, the indoor gun propellant combustion of second level medicine, the powder gas of generation increase second level medicine room pressure, reach
After starting pressure, fire extinguisher bomb is to the exit movement of transmitting tube under the action of powder gas, and piston is in level-one coyote hole inner support frame
Support under remain stationary；
Step 4, after reaching setting time, the indoor propellant powder of level-one medicine is lighted by common igniter；
The powder gas generated in step 5, level-one coyote hole increases level-one medicine room pressure, when pressure is higher than second level coyote hole
When interior pressure, piston is under the action of two coyote hole internal pressure differences to the exit movement of transmitting tube；
Step 6, second level coyote hole expand opposite reduction in piston motion lower volume, delay the indoor pressure decline of second level medicine,
So that pressure is after improving bullet to push fire extinguisher bomb to move to exit portal, until being detached from the outlet of transmitting tube；
Step 7, piston and biography fire tool move under the action of powder gas in level-one coyote hole, until leaving transmitting tube
Outlet, common igniter, laser ignition tool, optical fiber and support frame exit transmitting tube from transmitting tube inlet.
Further, packing mode arming is used described in step 1, specific as follows:
Piston, the fiery tool of biography, second level coyote hole, propellant powder, optical fiber and fire extinguisher bomb are subjected to whole filling first, then by level-one
Coyote hole, support frame, common igniter and laser ignition tool are loaded into transmitting tube and have laser ignition to be connect with optical fiber.
Compared with prior art, the present invention its remarkable advantage is: (1) on the basis of classification coyote hole fire extinguisher bomb lift-off technology
On, realize lighting first for gunpowder in second level coyote hole by designing a laser-ignition unit, realize the low overload of fire extinguisher bomb,
The purpose of high initial speed transmitting；(2) distance of fire extinguisher bomb transmitting is improved, the range of fire extinguisher bomb effect is improved；(3) due to laser
Igniting is the mature technology applied with fire in a stove before fuel is added igniting, therefore can accurately control the duration of ignition delay of classification coyote hole, process
Securely and reliably, it is easy to accomplish.
