{System for recovering bullet warheads at indoor shooting ranges for firing with live ammunition}

The present invention relates to a salvage recovery system for an indoor chamber shot range, and more particularly, it relates to a salvage recovery system of an indoor chamber shot range, in particular, In the case of collecting the warhead, it is possible to safely recover the bullet close to the circular shape without crushing by using the rubber filler made of the rubber particles made of the rubber material having the heat resistance and the refractory property as the shock absorber. This system is designed to facilitate the separation of the warhead by using the vacuum pump and air blower and the recovery of the filler by the automatic equipment. will be.

Due to the nature of work, military personnel and police officers handling firearms such as rifles and pistols have been conducting fire drills for these personal firearms in order to cultivate the necessary fire capability in case of emergency and to maintain their combat power. These personalized fire drills are mainly carried out at indoor and outdoor zero and range shooting ranges. Heavy metals contained in warheads launched from such a range of shotguns cause serious environmental pollution, I was having a lot of difficulties.

First, in the case of military units, M16, K1 and other rifles mainly use indoor chamber shooting ranges. There are about 240 indoor chamber shooting ranges only in ROK Army, but they are scattered from noise and warheads Due to the pollution of heavy metal components such as lead, complaints from residents near the shooting range, and environmental protection groups' problems, most of the indoor shooting ranges are closed.

Indeed, in the case of an indoor chamber shooting range operated by the military, the warhead fired from a gun such as a pistol or a rifle strikes against walls and facilities near the target area, causing a large noise and dust. In particular, Thereby causing various problems such as polluting indoor air. In the case of an indoor shooting range, a waste tire or a tire chip may be placed behind the target in order to absorb the impact of the warhead, but heavy metal components such as lead and cadmium contained in the waste tire are scattered in the air due to collision with the warhead Rather, indoor air pollution has a disadvantage that it is higher.

In this way, the bullet of the bullet in the indoor shooting range collapsed and collapsed into the surrounding concrete wall or facilities, and the heavy metals such as lead contained in the bullet were accumulated in the air and the soil to contaminate air, soil and water quality. Recent studies have found that the lead content in the soil near the military site of a military unit is more than 1,200 times higher than the reference value.

In addition, the same problem of environmental pollution and complaints of the residents is raised in the case of the indoor and outdoor shooting ranges operated by the police and some commercial indoor shooting range facilities, and it is difficult for domestic indoor shooting ranges to be operated properly for the purpose there was.

Hereinafter, the structure and effect of the salvage gun recovery system according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic view for explaining a configuration of a salvage collecting system 100 of an indoor chamber shot range 1 according to the present invention. The salvage collecting system 1 includes a target plate 7 and a warhead collecting apparatus 10 In the form of a sectional view.

1, the structure of the indoor chamber shooting range 1 to which the present invention is applied is provided with a target plate 7 at a position spaced apart from the launching platform 5a by a distance of L ₁ , A warhead collecting device 10 is provided in the space from the rear to the wall 3 of the shooting range so that the warhead 6b fired from the gun 6a can be inserted into the warhead 6b.

The indoor chamber shot range 1 is installed on the ground surface 4 with a space in which the shooter 6 can stay in front of the launcher 5a and the shooter 6 is mounted on the launcher 5a with a gun 6a ) Or by holding the gun 6a by hand. In FIG. 1, reference numeral 5 denotes a 'firing position' at which the shooter 5 fires a gun 6a.

As shown in FIG. 1, the warhead collecting apparatus 10 has a rectangular triangular structure as a whole when viewed from a cross-sectional view along the longitudinal direction of the shooting range 1. The warhead collecting apparatus 10 has two sides The lower end support portions 17a are provided at the corners forming a pointed acute angle at the front and the lower end support portions 17a are provided at the corners of the front end of the wall 3 and the bottom layer 4a, Is firmly supported in its position by a support jaw 17 fixed to the bottom layer 4a.

The warhead collecting apparatus 10 includes a warhead collecting space 10a filled with rubber fillers 13 and a rubber mat 12 covering the top of the rubber fillers 13 accumulated in the warhead collecting space 10a. And a plurality of rubber blocks 11 laid one on top of the rubber mat 12 and arranged in a manner to be coupled to each other. A water spray pipe 14 capable of discharging water is provided at an upper corner of the warhead collecting device 10 and at least one fire detection is provided in the middle of the accumulation of the rubber fillers in the warhead trapping space 10a A sensor 16 is provided.

The fillers 13 made of the rubber material are in the form of particles having a size of 0.1 to 3 mm and preferably have a spherical shape as a whole and can be formed into various shapes such as an oval shape or a hexahedral shape . The rubber fillers 13 are made of a synthetic rubber material such as a polymer elastomer and are made of a silicone rubber material having excellent heat resistance and fire resistance in order to suppress fire caused by frictional heat with the warhead . In order to prevent environmental pollution, it should be made of rubber material not containing lead component.

In the present invention, the rubber filler (13) completely absorbs the impact of the warhead (6b) to stop the warhead (6b) safely without breakage. According to the experiment of the inventor of the present invention, When the size of the rubber fillers is too large to be greater than 3 mm, the rubber fillers are excessively broken due to the force of the warhead 6b, so that a lot of rubber fillers are generated in the warhead capture space 10a. If the material is too stiff, the warhead may break down or be too heavily deformed, which makes it difficult to recycle the warhead.

Therefore, in the present invention, the particle size of the fillers 13 of rubber material is set in the range of 0.1 to 3 mm, which means that the optimal particle size range capable of minimizing both the breakage of the warhead and the breakage of the rubber fillers It is a big meaning because it is found through.

Particularly, according to the experimental results of the present inventors, it has been found that when rubber fillers made of a silicone rubber-based material having fire resistance and heat resistance are used and the size range of the particles is set to 0.3 to 0.6 mm, the recovery efficiency of the warhead and the recycling efficiency , And most preferably, when the particle size of the rubber filler is set to 0.5 mm, it is possible to achieve the best shot recovering efficiency and the recycling efficiency of the rubber filler.

 A plurality of rubber fillers 13 are filled in the warhead collecting space 10a of the warhead collecting apparatus 10 so that the rubber mats 12 are covered on the upper portions of the fillers 13, The rubber blocks 11 are laid. Since the rubber mat (12) is a mat having a thickness of 3 to 30 mm, it is difficult to cover the entire area of the warhead capturing space (10a) with only one rubber mat. Therefore, Thereby covering the entire upper inclined surface of the warhead capture space 10a. The rubber mat (12) functions to cover the rubber fillers (13) in order to prevent the rubber fillers (13) from being blown into the air as dust because the rubber fillers (13) are so fine particles.

A plurality of rubber blocks 11 are placed on the rubber mat 12. The rubber blocks 11 serve to press the rubber mat 12 to prevent the rubber mat 12 from being blown or lifted, It primarily serves to reduce the momentum of the warhead to a large extent by first passing through when it comes.

The rubber blocks 11 and the rubber mat 12 fit into the warhead 6b and are forced to drill a large number of holes. However, since the holes are once opened due to the characteristics of the rubber material, The holes are passed through the holes through which the bullets of the rubber blocks 11 and the rubber mats 12 pass, even though the bullets are shot with hundreds or thousands of bullets, 10 does not leak out to the outside.

As shown in FIG. 1, the warhead collecting apparatus 10 has a cross-sectional structure of a right triangle as a whole, and a corner portion of the right angle is formed along a corner line where the wall 3 of the indoor shooting range building meets the bottom layer 4a . The upper surface of the warhead collecting apparatus 10 is inclined toward the target plate 7 so that the warhead 6b passing through the target plate 7 is incident on the upper surface of the warhead collecting apparatus 10 which is inclined. The reason why the top surface of the warhead collecting apparatus 10 is inclined in the direction in which the warhead is flying is to absorb the impact amount of the warhead as natural and smooth as possible and to prevent the accumulation of the filled rubber fillers 13 So that it can be maintained. If the arrangement of the rubber mat 12 and the rubber blocks 11 is arranged so as not to have a structure having an inclination angle of about 30 to 50 degrees as shown in FIG. 1 (for example, the rubber mat 12) The rubber mat 12 and the rubber blocks 11 immediately receive 100% of the impact of the warhead 6b so that the degree of damage due to penetration of the warhead is increased There is a problem that the rubber fillers 13 can easily leak out through the bullet holes formed in the rubber mat 12 and the rubber blocks 11. [ For this reason, the inventor of the present invention has determined that it is preferable that the upper surface of the warhead capture space 10a is inclined at an angle of about 30 to 50 degrees as shown in FIG.

Since the warhead capturing space 10a is inclined toward the target plate 7, the warp capturing space 10a tends to flow downward and collapse as a whole due to the weight of the rubber fillers 13 and the rubber blocks 11. [ In order to prevent this, the present invention is characterized in that a support jaw 17 is provided in front of the front of the warhead collecting apparatus 10 and the support jaw 17 is firmly fixed to the bottom layer 17, So that the weight of the rubber blocks 11 and the rubber filler 13 can be held down.

At least one fire detection sensor 16 is installed inside the warhead collecting apparatus 10 and the fire detection sensor 16 is connected to the control unit 15 through a sensor cable 16a, When a fire occurs in the space 10a and the temperature rises, it is detected and transmitted to the controller 15.

The warhead 6b emitted from the gun 6a has considerable kinetic energy and the bullet 6b having such a large kinetic energy enters into the warhead capturing space 10a and rubs against the rubber fillers 13 , There is a possibility that a fire may occur between the rubber fillers 13 due to this frictional heat. Of course, in order to prevent such a fire, according to the present invention, the material of the rubber fillers 13 is made of a silicone rubber material having heat resistance and fire resistance. However, even if the rubber fillers 13 are ignited, A fire detection sensor 16 is installed in the warhead trapping space 10a and a water spray pipe 14 capable of discharging water for fire extinguishing is installed on the upper end of the warhead trapping apparatus 10a And was installed at the corner portion.

The water spray pipe 14 is connected to a water supply means including a water supply pipe 141 and a connection portion thereof is provided with a motorized valve such as a solenoid valve 140 The signal enables the motorized valve to be operated remotely. Therefore, when the fire detection sensor 16 detects a temperature rise in the rubber fillers 13 and transmits the detected temperature rise to the control unit 15, the control unit 15 determines that the fire has occurred and promptly issues an open control signal to the electric valve And when the electric valve is opened, the water spray pipe 14 discharges a large amount of water into the warhead storage space 10a (see FIGS. 5 and 6).

On the other hand, the water spray pipe 14 is provided with a protective case 14a made of iron around the bulb to prevent it from being damaged. In FIG. 1, the water spray pipe 14 is shown in a circular cross-sectional shape, and a protective case 14a having a triangular cross-sectional shape as a whole is provided around the water spray pipe 14. The protection case 14a is made of a metal material having a sufficient rigidity such as steel or stainless steel. The protection case 14a has sufficient strength and thickness so as not to penetrate even if hit by the bullet, Should have.

A drainage facility for discharging the water discharged from the spray pipe 14 to the outside is provided in the lower part of the warhead collecting apparatus 10. The drainage facility will be described below. A drafting plate 18b is provided on the bottom surface of the warhead collection space 10a and an inclined water collecting pipe 18a is provided thereunder. The inclined water collecting pipe 18a, (18).

5 and 6) discharged from the water spray pipe 14 for fire extinguishing is used to cut off the fire on the rubber fillers 13, and then flows downwardly and downward, And then to the drainage pipe 18a and the drainage pipe 18 and then to the drainage storage tank 180 (see FIG. 6) and the water treatment facility 181 (see FIG. 6).

The sieve plate 18b provided on the bottom surface of the warhead accommodation space 10a blocks the rubber fillers 13 from passing therethrough and allows only the water W to pass therethrough. Since the particle size of the rubber fillers 13 used in the present invention is in the range of 0.1 to 3 mm, the hole size of the screening plate 18b is made smaller than the particle size of the rubber fillers 13, W only to escape and the rubber fillers 13 to be filtered.

In the present invention, the height (space) at which the drainage facility can be formed in the lower part of the warhead collecting apparatus 10 is secured by raising the bottom layer 4a of the shooting range 1 from the paper surface 4 by a predetermined height. Of course, in addition to the system shown in FIG. 1, it is also possible to design the structure of the drainage system and the bottom layer in various ways in which the firewater in the warhead collecting apparatus 10 can be siphoned out by withdrawing water for fire extinguishing.

In Fig. 1, reference numeral 7a denotes a stand for supporting the target plate 7, 6c denotes a flight path of the warhead 6b fired from the gun 6a, 14b denotes a flight valve of the spray pipe 14, (15).

In the meantime, the structure of the salvage collecting system of indoor chamber shot range according to the present invention is largely divided into the warhead collecting apparatus 10, the filling material replacing apparatus 20, the warhead separating and collecting apparatus 40 and the ventilator 100.

Among them, the structure and role of the warhead collecting apparatus 10 are as described above. The filling material exchanging apparatus 20 is provided with the rubber fillers 13 (FIG. 1) for collecting the warhead 6b collected in the warhead collecting apparatus 10 And the warheads 6b are transferred together to the bullet separating and collecting apparatus 40 provided outside and the rubber fillers 13 after the bullet is separated from the bullet separating and collecting apparatus 40 are transferred again to the warhead collecting apparatus 40 10) to fill it in.

The warhead separating and collecting device 40 separates the charged warhead 6b and the rubber fillers 13 from each other through the filler replacing device 20 so that the warhead is recovered according to the warhead and only the rubber fillers are collected .

Meanwhile, the ventilator 200 quickly draws out the air contaminated with the powder components and dust particles generated by performing a large amount of shotgun fire at the indoor chamber shooting range (1), and the wet scrubber And the fresh air and / or the fresh outside air are supplied into the indoor shooting range to prevent air pollution at the indoor shooting range and to maintain a clean indoor air environment. A plurality of air inlets 201 (see FIG. 2) are provided on the lower side of the wall surface of the indoor room shooting range 1.

5 and 6 are diagrams for explaining a method for recovering water W from a water spray pipe 14 when a fire 19 is generated by a frictional heat due to an impact of a warhead in a warhead collecting apparatus 10 in an empty chamber recovery system according to the present invention ) To quickly extinguish and extinguish. FIG. 5 shows a state in which a fire occurs in the warhead collecting space 10a of the warhead collecting apparatus and starts to discharge the water W from the water draining tube 14, and FIG. And the fire is extinguished by a water (W).

5, when a fire occurs in the rubber fillers 13 in the warhead collecting apparatus 10 due to the generation of frictional heat due to a strong impact of the warhead 6b, the fire detection sensor 16 detects the fire The temperature rise is detected promptly and the signal is transmitted to the control unit 15 through the sensor cable 16a. When the control unit 15 determines that a fire has occurred in the warhead collecting apparatus 10 by the signal of the fire detection sensor 16, the control unit 15 controls the water spray pipe 14 through the water spray pipe control cable 14b. The water of the water supply pipe 141 (see FIG. 3) is supplied to the water supply pipe 14 when the solenoid valve 140 is opened, thereby supplying an open control signal to the solenoid valve 140 , And the water (W) is discharged from the water spray pipe (14).

6, when a large amount of water W discharged from the water spray pipe 14 quickly covers the fire generating portion 19, the fire generated in the rubber fillers 13 is suppressed early, At this time, the discharged water (W) is discharged to the outside through a drainage facility provided in the lower part of the warhead collecting apparatus (10).

The water W discharged from the water spray pipe 14 is easily collected into the slop water collecting pipe 18a at the bottom of the warhead collecting device 10a, The rubber fillers 13 are caught by the engaging wall plate 18b and are not leaked toward the inclined water collecting pipe 18a because the engaging wall plate 18b is provided at the bottom portion of the warhead collecting device 10a, Only downward flows to the inclined water collecting pipe 18a.

The water W flowing into the sloping water collecting pipe portion 18a flows to a drainage storage tank 180 provided outside through a drain pipe 18. The drainage storage tank 180 stores the collected water, And then sent to the facility 181 to perform water treatment operations such as purification treatment.

The reason for setting the size of the rubber fillers 13 in the range of 0.1 to 3 mm in the present invention is to achieve the purpose of effectively collecting the warhead without damaging it, The particle size of the rubber fillers should be at least 3 mm or less so that the interstitial space between the rubber fillers is small and the air content necessary for the fire generation itself can be suppressed to some extent.

That is, when the particle size of the rubber fillers 13 is larger than 3 mm, the space between the gaps between the rubber fillers becomes larger and the air easily passes through the gaps, so that the content of oxygen contained in the air There is a risk that the fire will occur more easily. On the other hand, when the size of the rubber fillers 13 is kept at 1 mm or less, the space between the rubber fillers 13 is significantly reduced, and the content of oxygen existing in the space is extremely small Therefore, even if friction heat is generated due to the impact of the warhead, the possibility of occurrence of fire in the rubber fillers 13 is considerably reduced.

The present invention is basically equipped with a waterproofing facility capable of suppressing the fire in the event of a fire occurring in the space between the rubber fillers 13 in the warhead collecting apparatus 10. However, Is set to a fine size of 1 mm or less and the material itself is made of a silicone rubber material having heat resistance and fire resistance, thereby greatly reducing the risk of fire caused by frictional heat of the warhead.

FIG. 7 shows a state in which a plurality of warheads 6b are trapped between the rubber fillers 13 of the warhead collecting apparatus 1 in the salvage collecting system of the indoor chamber shot range according to the present invention. Since the sloped upper surface of the warhead collecting apparatus 10 has an angle of 30 to 50 with respect to the target plate 7, The kinetic energy of the warhead 6b is absorbed by the rubber fillers 13 safely and sufficiently so that the warhead 6b can be wound around the warp 6b, Can be maintained in a shape close to a circle without being damaged. As the warhead 6b penetrates, the rubber blocks 11 and the rubber mat 12 have a large number of penetration marks. Due to the nature of the rubber material, The rubber fillers (13) do not leak out. On the other hand, the rubber blocks 11 and the rubber mats 12, which are excessively damaged by the warhead 6b, may be repaired by replacing the rubber mats 12 when the warhead is separated and collected.
