Description
Technical field
The present invention relates to fire extinguisher bomb lift-off technology field, it is especially a kind of based on classification coyote hole fire extinguishing bullet launching 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 facilitate arrival, have the advantages that easy to use, power is big, it can be to avoid
Personnel are directly entered personnel hazard caused by the scene of a fire.Existing fire bullet is mainly the small-sized fire extinguisher bomb for being suitable for jettisoninging by hand,
Shortcoming, which is that volume weight is limited, causes payload lower, and then can effectively improve effective load using heavy caliber fire extinguisher bomb
Lotus improves fire-fighting efficiency.
Traditional single coyote hole emitter of heavy caliber generallys use raising dress to realize the high initial speed of big quality fire extinguisher bomb
The mode of dose, however merely increase explosive payload will lead to fire extinguishing emitter in pressure it is excessive, be unfavorable for emission security.This
Outside, existing some for example casual powder charge lift-off technologies of method for improving fire extinguisher bomb initial velocity, liquid medicine lift-off technology etc. are still in spy
Rope conceptual phase has not been put to application, and is unfavorable for effectively controlling the chamber inner movement process of fire extinguisher bomb, is unfavorable for fire extinguisher bomb transmitting
Safety.
Summary of the invention
The object of the present invention is to provide one kind can accurately control the classification coyote hole duration of ignition, effectively improves fire extinguisher bomb
Range, realize fire extinguisher bomb it is low overload, high initial speed based on classification coyote hole fire extinguishing bullet launching device and method.
The technical solution for realizing the aim of the invention is as follows: a kind of fire extinguishing bullet launching device based on classification coyote hole, including
The fire in a stove before fuel is added, level-one coyote hole, piston, second level coyote hole and the fire extinguisher bomb being successively set in transmitting tube；The level-one coyote hole and second level medicine
Interior is provided with propellant powder；Biography fire tool is provided in the level-one coyote hole；Igniter is provided in the second level coyote hole.
Further, biography fire tool and be in contact between piston but there is no rigid connection, pass fire tool intercept piston to
The direction of level-one coyote hole is mobile.
Further, relatively independent between the level-one coyote hole and second level coyote hole, energy and mass exchange do not occur.
Further, using packing mode arming.
A kind of fire extinguisher bomb launching technique based on classification coyote hole, comprising the following steps:
The fire in a stove before fuel is added, level-one coyote hole, piston, second level coyote hole and fire extinguisher bomb are set gradually in step 1, transmitting tube, and using packing
Mode arming；
Step 2 fires ignition charge in second level coyote hole using igniter, and ignition charge lights the indoor propellant powder of second level 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 travels forward under the action of powder gas, and piston passes in level-one coyote hole to be protected under the support that fire has
It holds static；
Step 4, after reaching setting time, by percussion lock percussion level-one coyote hole the fire in a stove before fuel is added, light pass fire tool in biography
Gunpowder；
Step 5, starting mix burn in passing fire tool and light the indoor propellant powder of level-one medicine, pass fire tool during the launch process
It is not subjected to displacement；
The powder gas generated in step 6, level-one coyote hole increases medicine room pressure, when pressure is higher than second level coyote hole internal pressure
When power, piston travels forward under the action of level-one medicine room pressure；
Step 7, second level coyote hole expand opposite reduction in piston motion lower volume, delay the indoor pressure decline of second level medicine,
Until fire extinguisher bomb is detached from transmitting tube；
Step 8, piston move under the action of powder gas in level-one coyote hole, until leaving transmitting tube outlet, pass
Fire tool exits transmitting tube from transmitting tube inlet.
Further, packing mode arming is used described in step 1, specific as follows:
It is loaded using packing mode, is first integrally packed into piston, second level coyote hole and fire extinguisher bomb in transmitting tube, then will
Level-one coyote hole is loaded into transmitting tube, is positioned by passing fire tool and piston contact.
Compared with prior art, the present invention its remarkable advantage is: (1) passing through setting level-one coyote hole, second level coyote hole, work
Plug can effectively realize the accurate timesharing igniting of two-stage coyote hole, the indoor pressure ratio of two-stage medicine, energy are adjusted by piston motion
The volume that second level coyote hole is enough effectively reduced increases rate, with reach slow down bullet after pressure decrease speed, improve powder gas to going out
The mechanical efficiency of fiery bullet realizes the low overload of heavy caliber fire extinguisher bomb, the transmitting purpose of high initial speed；(2) pass through two coyote hole gunpowder point
The design that do not light a fire can accurately control the duration of ignition of I and II coyote hole, the consistency of emission process is better achieved；(3)
By rigidly passing the design of fire tool in main ingredient room, piston can be effectively prevent to move backward, guarantee the safety of emission process.
