CN1037371C - Hand grenade for training - Google Patents

Abstract

The present invention relates to a training hand grenade which is composed of a paper cartridge, fine river sand, bluing ferrous powder, gumming dirt, firework explosive, a blasting fuse and a lanyard device component. The training hand grenade has an effect on simulation of real hand grenade, but the training hand grenade is safe, reliable and non-lethal. The training hand grenade can be used for army training and rehearsal of screen and video.

Description

Hand grenade for training and preparation method thereof

The invention relates to hand grenade for training and preparation method thereof.

Army and militia training and the employed grenade of tactical manoeuvre generally adopt the actual combat grenade of wooden handle formula or the model grenade of wooden handle iron head at present.These two kinds of grenades all exist shortcoming when training.Under battle conditions grenade easily goes out danger sometimes, particularly during the training of new recruits, can cause certain psychology to constrain to the new recruit.Just in case accidentally drop or misoperation, after the body blast, tend to cause casualty accident.And the model grenade of using on the playground, noiseless, light, cigarette effect lack intuitive, can not reach the combat training effect.In addition, disclose a kind of fireworks display grenade in CN91201978.6, but a kind of structure of grenade is disclosed just this utility model, and complex structure is about tens parts and forms, and do not have function (i.e. sound, light, cigarette) effect, more do not have explosive formulation and technological process, be difficult to carry out.

The present inventor is through studying intensively for many years, invented a kind of novel not only safety, but also the hand grenade for training of the Synthetic Theatre of War effect of sound, light cigarette effect.It not only can guarantee to finish the training mission of army but also can reduce defense spending.In addition, it also can be used on film, TV rehearsal fight scene is used.

Product of the present invention is by platen cylinder, thin river sand, the iron powder that turns blue (iron powder), clay, explosive, safety fuse and draws fiery device partly to constitute.

The platen cylinder is to be formed by the laminated paper compacting.The back broken scraps of paper of easy formation that break do not constitute a threat to people and buildings.

Thin river sand, promptly finer fine sand, its particle diameter should be less than 1 millimeter.

The iron powder that turns blue is that a kind of lathe blanking iron filings make through Overheating Treatment, and clay is to use general loess clay, it and the iron powder that turns blue, and thin river sand mainly plays counterweight and regulates and press the heart.Make that under the explosion product effect flowability that Ju You Lang is good and dispersed is difficult for hurting sb.'s feelings.

Explosive is based on following firework medicament, it be not only have stronger sound, light, cigarette effect, and in closely to people and buildings etc., do not have damaging effect.

The orthographic plan of below representing hand grenade for training

Fig. 1-1 is the synoptic diagram of grenade

Fig. 1-2 is bullet anatomical planes figure

Among the figure: 1, word bomb tube, 2, clay, 3, safety fuse, 4, explosive, 5, thin river sand, 5, connecting portion;

Fig. 1-3 is for playing handle anatomical planes figure

Among the figure: 7, connecting portion, 8, draw fiery device, 9, lanyard, 10, draw fiery iron hoop, 11, dress ring portion position;

Data wherein following (pressing length-gauge):

Bullet length overall 90-95 millimeter is counted 7 millimeters of 15 millimeters in clay, 10 millimeters of pyroelectric charge, 5 millimeters of thin river sands, iron powder 40-43 millimeter, thin river sands by the wooden handle side.

Play 15 millimeters of the long 155-160 millimeter of shank, connecting portions.

The body length overall is the 230-240 millimeter.(by weight)

The heavy 430-440 gram of bullet (wherein tube weighs 96 grams, clay 38 grams, pyroelectric charge 25 grams, thin river sand totally 50 grams) plays handle and accessory 70-80 gram, body gross weight 500-520 gram.

The concrete step is poly-:

Pyroelectric charge with in the above-mentioned prescription is mixed in proportion, and it is standby to cross 80 mesh sieves.The safety fuse of in tube, packing into, and fix with compacting earth, then load onto shell case, add above-mentioned pyroelectric charge 25 grams, add thin river sand, iron powder, the thin river sand of afore mentioned rules amount later in turn, stick the scraps of paper again, become required bullet.

On the other hand, get one of above-mentioned wooden handle, adorn a firing mechanism after, add protective cover.

At last bullet and wooden handle are fitted together, fixing with three bamboo pins promptly becomes hand grenade for training of the present invention.

Effect of the present invention is as follows:

1, explosion effect test

Word bomb tube and the test of counterweight filling inert material crumbliness

Test objective

Observe word bomb tube and counterweight inert material pulverized degree under effect medicine explosive action.Under the effect of effect medicine, cylinder and inert material will form fragment not of uniform size and form, and disperse towards periphery, may cause certain calibration of causing injury to human body.When well-designed, only allow not damaged, slight damage and minor injury, restriction is hit people's fragment and is answered≤12j/cm2 than kinetic energy, as the standard of check.

Test-results

Through repeated tests, after the effect medicine blast, the word bomb tube is burst, layering and fragmentation, a small amount of glue blended inert material is broken into very fritter and powder, show when strong closely causing personnel's slight following damage, more than or equal to the 5m place, then will not constitute and cause injury apart from the quick-fried heart.

The acoustic effect test

Test objective

After purpose is to weigh hand grenade for training blast,,, safe in utilization when guaranteeing to train to the situation of causing injury of animal from a fried some different distance place.

Testing tool

Adopt ND6 impulse precision sound level meter (state-run red equipment factory, China, Jiangxi).

Test result

Acoustic pressure test result date dummy round orientation (°) distance (m) acoustic pressure (dB) 93.9.21 NO.1 ⊥ bullet axle 5 14993.9.21 NO.2 and bullet axle 5 146.593.9.21 NO.3 ⊥ bullet axle 10 14793.9.21 NO.4 at 45 and bullet axle 10 14593.9.21 NO.5 at 45 and bullet axle at 45 15 140

Acoustic pressure and superpressure value conversion relation acoustic pressure (dB) 100 120 140 160 180 200 superpressures (normal atmosphere) 0.00002 0.0002 0.0 2 0.02 0.2 2 acoustic pressure test results show apart from quick-fried heart R 〉=5m the people not to be had any injury.

Photoeffect is observed

Effect medicine composition design, having controlled luminosity can not be very strong, so the effect of the light that only detects by an unaided eye when testing.With the naked eye repeatedly observing photoeffect apart from the quick-fried heart about 30m place, luminous diameter is about 1.3-1.7, illustrates that reagent combination has reached effects visible to a certain degree, especially between the lights or during cloudy the test, photoeffect is more obvious.

The smoke, mists and clouds effect test

The smoke, mists and clouds effect test is one of important effect of the true grenade effect of simulation.According to prescription control, after the blast of effect medicine, at the about 30m of the quick-fried heart of distance place, visual inspection can be seen the white smoke, mists and clouds (under calm condition) of about 2-3m diameter.

2, ignition reliability test

Test 128 in June, 93 to August altogether, and only misfire is 1, and effectively sparking rate reaches more than 99%.And, in case get angry then the effect medicine almost 100% is blasted, generation sound, light, cigarette effect.

3, delay time test

Draw the ignition blasting test through 30, measure with stopwatch (three), be 3-4 between second its time of lag, and be 3.8s average delay time, and time of lag is accurately reliable, has reached the design objective requirement fully.

Claims (3)

1, hand grenade for training, it is characterized in that by word bomb tube (1), thin river sand (5), the iron powder that turns blue, clay (2), pyroelectric charge (4), safety fuse (3) and draw fiery device part (8) to constitute, thin river sand is a particle diameter less than 1 millimeter river sand, the iron powder that turns blue is a kind of lathe blanking iron filings, obtain clay through heat treatment process: pyroelectric charge: thin river sand is 38: 25: 50 by weight.
