Abstract
The utility model discloses a salvo bomb used for national guests welcoming and great celebrating activities, comprising a high pressure chamber, a low pressure chamber, a powder charge, a primer, etc. The utility model adopts the high and the low pressure chambers and the principium of quadric rupturing membrane vocalization, and can achieve the ideal sound effect by only charging a small quantity of powder. The main component parts of the utility model can be reused many times, and the salvo bomb can bomb inside a salvo and can also bomb in bareness outside a salvo. The high-low pressure double-film-type salvo bomb solves the problems of the sense of grating ears with noise, the sense of breading, out thrown articles, environmental pollution, etc. Existing in the salvo bombs in prior art, and enhances functional reliability and using security. The high-low pressure double-film-type salvo bomb has the advantages of loud sound, good tone quality and moderate sound intensity, and is an ideal device for foreign affair activities and celebrating activities.
Description
The utility model system relates to the ceremony shell of national welcome (welcoming the head of state or Head of Government) and great celebration activity use.
Active service salvo bullet adopts the blank cartridge emission principle of band gascheck, because the gunpowder loading density is low, and the interior no bullet of thorax stops in the emission process, thereby is difficult to guarantee gunpowder reliable ignition and smooth combustion, causes salvo sound unstable properties.Particularly under low temperature, moist climatic condition, often occur missing fire or situation that the sound is unusual; Because powder burning is insufficient, generate a large amount of peculiar smell toxic gases in the emission process, environmental pollution is serious; Owing in the gascheck shattering process, generate a large amount of thorax mouth fall-outs, not only increased on-the-spot cleaning works amount, the more important thing is when under the wind weather condition is arranged, using the phenomenon that often makes a difference the salvo normal running even bullet or screening fan gunner eyes occur blocking.Thereby active service salvo bullet can not adapt to the needs of welcome and great celebration activity.
Task of the present utility model is a kind of novel salvo bullet that can eliminate above-mentioned defective, suit the requirements of design.
The utility model is realized as follows: full bullet mainly is made up of body, powder charge and the fire in a stove before fuel is added three parts.Light charge has certain loading density in the less hyperbaric chamber of volume, can keep smooth combustion after igniting, produces a large amount of high temperature, high pressure powder gases.After reaching certain pressure in the hyperbaric chamber, powder gases breaks through the hyperbaric chamber diaphragm along the uniform through hole of grate, enters low-pressure chamber.With the gunpowder residue of powder gases ejection, in low-pressure chamber, burn away on a small quantity.Along with the increase of powder gases amount, the low-pressure chamber internal pressure raises gradually.After reaching certain pressure, break through the low-pressure chamber diaphragm along pregroove marks, a large amount of powder gases spray thereupon, send the strong shock wave sound simultaneously, and this is the required sound of salvo.
The utility model adopts high-low pressure coyote hole, secondary rupture of membranes sounding principle, only needs light charge can reach desirable effects,sound.Its stable performance, reliable effect, safe in utilization, sound is loud and clear, tonequality is simple and honest, the sound intensity is appropriate, does not have outer parabolic, environmentally safe in the airing of views process.It both can airing of views in big gun, also can expose airing of views outside big gun, and main zero, parts can be repeatedly used.
Below in conjunction with accompanying drawing technical pattern is further described: body (15) is made up of hyperbaric chamber (13) and low-pressure chamber (14).Hyperbaric chamber (13) comprises hyperbaric chamber body (6), grate (7), hyperbaric chamber diaphragm (8) and back-up ring parts such as (9), links to each other in the mode of being spirally connected with the fire in a stove before fuel is added (11).Hyperbaric chamber body (6) is the basic part in salvo bullet hyperbaric chamber (13), adopts high strength, impact-resistant metal material to make.The existing restraining powder gases outflow of grate (7), to regulate the effect of hyperbaric chamber pressure, have again and stop that gunpowder medicine grain, the surplus medicine of restriction are with the outer effect of spraying of gas, have equally distributed a plurality of small through hole on it, its regularity of distribution and aperture are important structural parameters, can guarantee stable, the fully burning of fire combustion, and don't make hyperbaric chamber (13) internal pressure too high.Hyperbaric chamber diaphragm (8) is to be that the metallic plate of 0.4～1.0 millimeter (optimum thickness is 0.6 millimeter) is stamped to form by thickness, and the grate aperture by hyperbaric chamber diaphragm one end be processed into double tapered at the bottom of nest, so that do not sheared when making hyperbaric chamber diaphragm (8) rupture of membranes, and drawn distortion back is washed open.Do not produce splash when this has not only guaranteed rupture of membranes, but also help eliminating flareback.Back-up ring (9) is a special spring collar, plays fixedly grate (7) and hyperbaric chamber diaphragm (8).
Low-pressure chamber (14) comprises low-pressure chamber body (5), low-pressure chamber diaphragm (3) and compresses spiral shell parts such as (1), constituted the shell profile of salvo bullet jointly with the root edge part of hyperbaric chamber body (6).Low-pressure chamber diaphragm (3) is in order to control low-pressure chamber (14) internal pressure, for guaranteeing diaphragm rupture of membranes smoothly under the powder gases effect, and do not have fragment and flies out, and is carved with radially pregroove marks in its rupture of membranes zone.This diaphragm is that the metallic plate of 2.0～3.0 millimeters (optimum thickness is 2.5 millimeters) is made by thickness.Compress spiral shell (1) and made by aluminum metal, interior edge steel lining (2) is to prevent compressing spiral shell (1) inner surface gross distortion owing to the impact that is subjected to rip-panel makes in low-pressure chamber diaphragm (3) the rupture of membranes process.
Two one 55 gunpowder are selected in powder charge of the present utility model (12) for use, in the hyperbaric chamber body (6) of directly packing into.
The same electric primer that adopts of the utility model with active service salvo bullet.For guaranteeing that reliable ignition and elimination to the pollution of environment, have replaced universe point gunpowder-black powder with smokeless gun propellant many-125 in the fire in a stove before fuel is added (11).
The utility model adopts the seal with elastometic washer structure, rubber ring (4,10) selection standard spare, but its corresponding sealed groove has been done special processing, to guarantee the excellent sealing in duties, the use.
