Various embodiments generally relate to an eco-friendly smart indoor live ammunition shooting range facility system, and more particularly, to an eco-friendly smart indoor live ammunition shooting range facility system capable of quickly and reliably discharging a harmful substance containing a heavy metal, such as lead (lead fume) and copper, generated due to live ammunition shooting, realizing various shooting training situations by providing a smart target different from an existing simple fixed type target, and forming an eco-friendly live ammunition shooting range by recovering an original bullet head as it is in a beaten zone.
Due to the nature of their works, military units or police stations that handle firearms such as rifles and pistols have been continuously conducting shooting training for these individual firearms in order to cultivate shooting ability required in case of emergency and maintain combat power.
Shooting training using these individual firearms is mainly conducted at indoor or outdoor zero point shooting ranges and real shooting ranges. Since there is a problem in that heavy metals contained in bullet heads fired at such live ammunition shooting ranges seriously pollute the surrounding environment, there exist considerable difficulties in disposing of the bullet heads. In other words, a bullet head fired from a firearm collides with the iron plate of a shooting range to generate lead fume and dust, and as the fine powders thereof are scattered into the air, there arises a problem in that air pollution occurs severely.
Actually, in an indoor live ammunition shooting range operated by the military, bullet heads fired from firearms such as pistols and rifles collide with the iron plate of a beaten zone or walls and facilities near the beaten zone to generate loud noise and dust. In particular, there arise various problems such as polluting the indoor air as heavy metal components scatter from the bullet heads crushed due to the collision.
In the case of an indoor shooting range, waste tires or tire chips are placed behind a target to absorb the impact of bullet heads. However, since heavy metal components such as lead and cadmium contained in the waste tires are scattered as dust into the air due to collision with the bullet heads, there is caused a disadvantage of further increasing indoor air pollution, and as a result, it came to the point that the operation of indoor live ammunition shooting ranges for military units and police stations is stopped.
In addition, as such, as, in the indoor shooting range, the bullet heads of live ammunitions hit the iron plate of the beaten zone or a surrounding concrete barrier or facility and are broken and scattered, a problem is caused in that heavy metal components such as lead contained in the bullet heads are accumulated in the air and soil as they are, thereby polluting the qualities of the air, soil and water. According to a recent investigation, there is a case where lead component has been detected up to 1200 times a standard value in the soil near a live ammunition shooting range of a military unit.
In particular, there is a problem in that exhaust gas generated from a barrel at a shooting lane where a shooter is positioned directly exerts an influence on the shooter.
Accordingly, in order to solve the above problems and quickly normalize the operation of indoor shooting ranges installed in military units and police training centers, it should be possible to prevent the pollution of air by heavy metals due to shooting of live ammunitions.
In the meantime, a conventional live ammunition shooting range has a disadvantage in that an operation of replacing a target is cumbersome because a shooting target device should replace the target every time a shooting trainee is changed.
Furthermore, in the conventional art, in a process in which a shooting trainee performs shooting, in the case of long-distance shooting, it is difficult to clearly check with the naked eye which part of a target is penetrated by a fired bullet head. Therefore, a problem is caused in that the quality of actual shooting training is greatly reduced because measures such as correcting a shooting posture or correcting the gunsight of a gun cannot be taken during shooting even when, for example, a bullet head greatly deviates from a target or does not hit an intended part of a target.
Various embodiments are directed to an eco-friendly smart indoor live ammunition shooting range facility system capable of quickly and reliably discharging a harmful substance containing a heavy metal, such as lead (lead fume) and copper, generated due to live ammunition shooting, realizing various shooting training situations by providing a smart target different from an existing simple fixed type target, and forming an eco-friendly live ammunition shooting range by recovering an original bullet head as it is in a beaten zone.

The suction inlets 1422 may be configured such that the openings thereof are opened directly downward or toward a target, but may be configured such that the openings thereof are covered with a nonwoven fabric or a mesh net or are opened sideward to be prevented from being clogged by a foreign substance or the like.
The floor exhaust unit 1500 is configured to be installed on the floor of the indoor live ammunition shooting range to exhaust air in the indoor live ammunition shooting range. Gas containing a harmful substance generated by live ammunition shooting generally sinks downward due to its weight. In this consideration, the floor exhaust unit 1500 is to suck air convecting on the floor in front of a shooting position of the indoor live ammunition shooting range, from a side surface adjacent to the floor.
In detail, the floor exhaust unit 1500 is configured to include floor suction inlets 1510, which are installed on one side surface, preferably, both side surfaces, adjacent to the floor in a space in front of a shooting position of the indoor live ammunition shooting range, and floor suction ducts (not illustrated), which communicate with the floor suction inlets 1510.
The floor suction inlets 1510 may be covered with a nonwoven fabric or a mesh net to prevent a foreign substance from being introduced.
The floor suction ducts (not illustrated) are configured to be connected to the main suction duct (the common suction duct or the individual suction ducts) of the suction driving unit 1700 to be described below.
The position of the floor exhaust unit 1500 is preferably configured as a position corresponding to the ceiling exhaust unit for a shooter 1410 of the ceiling exhaust unit 1400, that is, a position directly below the ceiling exhaust unit for a shooter 1410.
The beaten zone exhaust unit 1600 is configured to be installed on the side of the bullet head recovery facility 4000 to exhaust air from a beaten zone. The beaten zone exhaust unit 1600 is to suck and exhaust air containing a harmful substance generated at the beaten zone.
In detail, the beaten zone exhaust unit 1600 includes a beaten zone side surface suction duct 1610 which is installed on the side walls of the shooting range in front of the beaten zone of the bullet head recovery facility 4000, and suction inlets (not illustrated) which are provided at intervals in the beaten zone side surface suction duct 1610.
At least one beaten zone suction duct 1610 may be configured. The at least one beaten zone suction duct 1610 may be configured to be connected to the main suction duct (the common suction duct or the individual suction ducts) of the suction driving unit 1700 to be described below, or may be configured to be joined at the upper end thereof to the suction duct (the second suction duct) 1421 of the ceiling exhaust unit for a target 1420.
The suction driving unit 1700 is configured to suck air from the ceiling exhaust unit 1400 and the floor exhaust unit 1500.
The suction driving unit 1700 includes a main suction duct 1710 which is connected to the ceiling exhaust unit 1400 and the floor exhaust unit 1500, and a suction fan 1720 which is installed on the distal end path of the main suction duct 1710 and is driven to suck and exhaust air.
The main suction duct 1710 may be configured as a common suction duct which is branched and connected to the ceiling exhaust unit 1400 and the floor exhaust unit 1500, and may be configured as individual suction ducts which are separately connected to the ceiling exhaust unit 1400 and the floor exhaust unit 1500, respectively.
The suction driving unit 1700 may further include a sub suction fan which, in assistance to the suction fan 1720, is provided in a suction duct (an individual suction duct) connected to a corresponding exhaust unit to suck air therefrom.
The purification unit 1800 is configured to filter and discharge to the outside the exhaust air exhausted from the ceiling exhaust unit 1400, the floor exhaust unit 1500 and the beaten zone exhaust unit 1600 by the suction driving unit 1700.
In detail, the purification unit 1800 may be configured by a wet scrubber which is installed on the distal end of the exhaust line (suction duct) of the suction fan 1720 to purify and exhaust to the outside air polluted with gunpowder components and dust generated by ammunition shooting in the indoor live ammunition shooting range.
Water used as a scrubbing water is introduced into the purification unit 1800 as a scrubber. Since water discharged from the scrubber contains pollutants such as gunpowder components and dust, the purification unit 1800 may be configured to purity wastewater by a water treatment device and drain purified water into a sewer pipe.
On the other hand, the ventilation facility 1000 may further include a barrel exhaust gas floor suction unit installed on the floor directly below the front of a shooting position in the indoor live ammunition shooting range; a target floor suction unit installed on the floor directly below a target position or a bullet head recovery unit or directly below the front of the target position or the bullet head recovery unit; and an intermediate floor suction unit installed on the floor between a shooting position and the target position.
These suction units may be connected to the main suction duct in a branched manner or to the individual suction ducts, and a common suction fan or separate suction fans and/or assistant suction fans may be configured to suck indoor air therefrom.
The intermediate floor suction unit may be configured to be embedded in a state in which the upper part thereof is exposed on the surface of the floor, or may be configured to be provided in the body of a block.
The intermediate floor suction unit may be installed in various shapes according to the specification of the indoor live ammunition shooting range and a shooting method. For example, as a suction duct, a plurality of pipelines may be installed over the entire surface of the floor by being connected to each other, and may be locally installed over a plurality of positions of the floor. Such an intermediate floor suction unit may substantially effectively suck air containing a harmful substance which is generated, specifically, during mobile shooting (or shooting training).
The ventilation facility 1000 may further include a plurality of fire detectors each of which is configured at a predetermined position of the indoor live ammunition shooting range to detect polluted gas and transmit a detection signal to the control facility 5000. The control facility 5000 is implemented to control the air supply fan 1320, the sub air supply fan, the suction fan 1720 and the sub suction fan entirely or selectively according to a concentration detected on the basis of the detection signal detected in the fire detector and by varying a rotation load (a rotation RPM).
Next, the targeting device facility 2000 which is installed in the indoor live ammunition shooting range and is configured to provide a shooting target will be described.
Target Device Facility 2000
A first embodiment of the target device facility 2000 generally includes, as illustrated in
In detail, as illustrated in
The screen-type target device 2100 generally includes a mounting case 2110, a roll screen accommodation case 2120, folding-unfolding driving means 2130 and roll screen means 2140, and may further include mounting case posture driving means 2150.
In detail, the screen-type target device 2100 according to the first embodiment includes, as illustrated in
The mounting case 2110 is formed to have a size corresponding to the lengthwise size of the roll screen accommodation case 2120. That is to say, the mounting case 2110 is formed in the shape of a rectangular housing which is long in a length direction.
Some components of the folding-unfolding driving means 2130 to be described below are provided to be accommodated in the mounting case 2110.
The mounting case 2110 may be formed with an extended cover case 2111 which extends downward by a predetermined length from both lower sides of the mounting case 2110 to prevent an X-shaped foldable link member 2131 constituting the folding-unfolding driving means 2130 to be described below and/or the roll screen accommodation case 2120 from being exposed to the outside in a state in which the X-shaped foldable link member 2131 is folded.
The extended cover case 2111 may be configured to cover only the X-shaped foldable link member 2131 as illustrated by the solid line in
Similarly to the mounting case 2110, the roll screen accommodation case 2120 is formed in the shape of a rectangular housing which is long in a length direction.
The roll screen member 2142 of the roll screen means 2140 to be described below is provided in the roll screen accommodation case 2120 to be capable of being drawn in and out.
The roll screen accommodation case 2120 is extended downward and is length-adjusted to an original position again, by the folding-unfolding driving means 2130 interposed between the roll screen accommodation case 2120 and the mounting case 2110.
The folding-unfolding driving means 2130 may be configured to include the X-shaped foldable link member 2131 which is formed by connecting a plurality of X-shaped links 2131a whose intersecting centers and ends are hinged and in which both ends of the uppermost X-shaped link 2131a are hingedly coupled to the mounting case 2110 and both ends of the lowermost X-shaped link 2131a are hingedly coupled to the roll screen accommodation case 2120; a driving motor (not illustrated) which is provided in the mounting case 2110 to rotate; a pulley member which is provided on the rotation shaft of the driving motor; a driving control circuit module (not illustrated) which is provided in the mounting case 2110 and controls the driving motor to rotate by a control signal from the control facility 5000; and a length adjustment wire 2132 whose one end is fixed to the pulley member and the other end is fixed to the roll screen accommodation case 2120. When the rotation shaft of the driving motor is configured to be extended to wind and unwind the length adjustment wire 2132, the pulley member may be omitted.
The X-shaped foldable link member 2131 is configured such that both ends of the plurality of X-shaped links 2131a which have unit centers 2131b are continuously connected in a zigzag pattern and each unit center 2131b of the X-shaped link 2131a is hinged.
The X-shaped foldable link member 2131 may be multiply folded and unfolded as the unit centers 2131b are moved up and down by winding and unwinding of the length adjustment wire 2132 through rotation driving by the forward and reverse rotation of the driving motor.
In other words, as the length adjustment wire 2132 connected to the roll screen accommodation case 2120 or the lowermost unit center 2131b is wound or unwound by the driving motor, the X-shaped foldable link member 2131 lifts the lowermost unit center 2131b or lowers the lowermost unit center 2131b by a weight according to the load of the roll screen accommodation case 2120. Accordingly, as the distance between the unit centers 2131b is changed, the X-shaped foldable link member 2131 executes a folding movement in which a length (the length or height of an entire shape) in a vertical direction is adjusted.
Instead that the other end of the length adjustment wire 2132 is fixed to the roll screen accommodation case 2120, the length adjustment wire 2132 may be connected to the unit center 2131b of the lowermost X-shaped link 2131a for smoother and more efficient folding, which is preferable than being fixed to the roll screen accommodation case 2120.
The roll screen means 2140 is configured such that the roll screen member 2142 accommodated in the roll screen accommodation case 2120 may be drawn in and out. The roll screen means 2140 includes a roll screen rotation shaft 2141 which is provided in the roll screen accommodation case 2120 to be capable of being rotated in forward and reverse directions; the roll screen member 2142 which is provided on the roll screen rotation shaft 2141 to be able to be unwound and wound; a pulley member 2143 which is provided on one end or both ends of the roll screen rotation shaft 2141; a driving motor 2144 which is provided on the other side of the roll screen accommodation case 2120 to be capable of forward and reverse rotations; a driving belt 2145 which transfers the rotational driving force of the drive motor 2144 to the pulley member 2143, and a driving control circuit module 2146 which is provided in the roll screen accommodation case 2120 and controls the driving motor 2144 to rotate by a control signal of the control facility 5000.
The pulley member 2143 and the driving belt 2145 may be replaced with another driving force transfer means (e.g., a gear train, etc.) capable of transferring the rotational driving force of the driving motor 2144 to the roll screen rotation shaft 2141.
The lower end of the roll screen member 2142 is provided with a weight bar 2147 for stably maintaining the unfolded state of the roll screen member 2142 and minimizing shaking of the roll screen member 2142 due to live ammunition shooting.
In the screen-type target device 2100, in order to more stably maintain the unfolded state of the roll screen member 2142, the weight bar 2147 may be made of a magnetic material such as a metal, and may further include a projection 2148 (see
The projection 2148 may be formed as a U-shaped block capable of accommodating the weight bar 2147, and the magnet body may be provided on any one side surface, both side surfaces or a bottom surface in the U-shaped block.
In this configuration, when the weight bar 2147 is adjacent to the projection 2148 in a state in which the roll screen member 2142 is drawn out and is thus deployed, the weight bar 2147 is attached to the projection 2148 by the magnetic force of the magnet body. By executing live ammunition shooting in this state, the unfolded state of the roll screen member 2142 may be stably maintained, and shaking of the roll screen member 2142 due to live ammunition shooting may be minimized.
The projector 2200 displays various targets, i.e., targets such as a single static/dynamic body shape or a plurality of static/dynamic body shapes and a plurality of static/dynamic tanks or airplanes, on the screen-type target device 2100 through the target device facility control module of the control facility 5000 to be described below in detail. Furthermore, a target (a target image) is also controlled in its size by the control facility 5000 to be displayed on the screen-type target device 2100.
Lighting means 2210 is additionally configured on one side of the projector 2200.
The target detection device detects whether a target displayed on the roll screen member 2142 of the screen-type target device 2100 by the projector 2200 is hit, detects the degree of spoilage of the screen-type target device 2100 due to passage of a bullet head, and transmits a detection result to the target device facility control module of the control facility 5000. The target device facility control module of the control facility 5000 analyzes the detection result, and causes screen movement (upward and downward movement) and/or target image movement to be executed through the target image position change device.
In detail, the target detection device may be implemented by a camera image sensor (for example, a CCD camera sensor) which is provided on the ceiling surface of a corresponding shooting lane to capture a target image displayed on the roll screen member 2142 of the screen-type target device 2100.
For example, the target detection device may be implemented by photographing means including a complementary metal oxide semiconductor (CMOS) image sensor or a charge coupled device (CCD) image sensor as a device which senses the intensity and color of an optical image and converts the optical image into digital image data.
The target detection device converts a captured target image into digital image data and transmits the digital image data to the target device facility control module of the control facility 5000.
