Description

  The present invention relates to a marking system for identifying a color by firing a colored ball enclosing paint and landing and bursting at a target location in the case of an inspection of a structure or a building, an accident or a disaster, etc. , By electronically controlling the accumulation and release of compressed air with an electromagnetic valve, and controlling the jet flow velocity of compressed air with an adjustment projection, it changes the outflow pressure of the compressed air ejected into the barrel and backspins the color ball. The present invention relates to a color ball launching device that generates and extends an effective range to ensure landing and keeps a discolored target continuously visible.

  Conventionally, in order to facilitate the subsequent work, the detected points are clearly displayed at the time of inspection of structures and structures, accidents and disasters, and the like. In recent years, in order to make it possible to visually detect a target from a distant place, a colored ball such as an elastic capsule encapsulating paint is fired with air or gas compression pressure to mark and rupture the impact. A method has been developed. In addition, similar devices have been developed to identify criminals for purposes such as crime prevention.

  In the work of marking the detection location, when it is difficult to reach a distance close to the target location, or when installing a color ball launcher on a moving body such as a drone truck, The color ball is fired while maintaining a certain distance from the target. Since it is necessary to fly and land at a certain distance after launch, expansion force such as compressed air or gas pressure is used as means for launching the color ball. The launch-type marking device does not require a person to approach the target and directly mark the target, so it is a very effective means in dangerous places and disasters, and for purposes such as identifying the criminal, It is also used in a wide variety of other situations.

  As for the flying accuracy of the color ball, it prevents the spherical bullets launched by the expansion force such as compressed air and gas pressure from descending toward the ground by drawing a parabola due to the decrease in flying speed and attraction. Therefore, a method is used in which a spin is applied to a spherical bullet to generate lift and extend the effective range. As a result, an effect against the attractive force is generated, and although the initial speed of the launch is slightly reduced, it is possible to fly a longer distance without increasing the launching power.

  In order to cause backspin in a spherical bullet, a method of generating rotation by hooking a bullet passing through the barrel by providing a projection or packing in the barrel has been used. However, when a bullet is caught on the projection, there is a problem that the projectile energy of the bullet is slightly reduced and the flight distance is shortened. Further, there has been a problem in that the projections and packings for generating back spin are worn by long-term use and the bullet cannot be sufficiently rotated and the effective range is reduced.

  A color ball formed by encapsulating a coating material in a capsule-like outer shell makes it possible to perform marking on a target from a remote location by destroying the outer shell by impact that has landed. Due to the above configuration, if a large expansion pressure is applied, the outer shell of the color ball is destroyed before or during the launch, which causes a problem that an excessive pressure cannot be applied to the bullet during the launch. . For this reason, it is necessary to limit the firing power to such an extent that the outer shell is not destroyed. However, in actual marking work, there is a demand for the development of a launching device that maintains a longer flight distance with the same firing pressure.

  In recent years, flying vehicles such as drones have been flying in various fields for the purpose of unmanned exploration and inspection, but flying vehicles such as drones are colored balls, unlike structures installed on the ground. The object (drone) on which the launching device is mounted is hovering in a state of being levitated in the air. Therefore, the force that receives the impact of the launch or the force that produces the reaction is extremely low, and it is greatly affected by the impact caused by the ejection of the high-pressure gas when firing the color ball. It was extremely difficult to hit.

  Therefore, even when a flying object such as a drone is equipped with a color ball launcher, development of a recoil-absorbing launcher that can perform highly accurate marking without being affected by the impact of the impact of the color ball launch. It was desired.

  Without destroying the outer shell of the color ball with the firing pressure, the reduction of the backspin effect due to wear does not occur even in repeated firing operations over a long period of time, extending the effective range at the same pressure as the conventional expansion pressure, It has been desired to develop a color ball launcher that can perform marking without being affected by the reaction by suppressing the impact of the launch, and can maintain the target continuously visible.

Hereinafter, a color ball launcher according to the present invention will be described in detail based on an embodiment shown in the drawings.
The color ball launcher 10 according to the present invention includes a barrel 20, a color ball 30, an electromagnetic valve 40, a compressed air accumulator tank 50, and a rear jet exhaust pipe 60.
The barrel 20 includes a launch port 22, an adjustment protrusion 24, and a compressed air inlet 26.
The electromagnetic valve 40 includes an opening / closing valve 42, an electromagnetic valve fitting port 44, a compressed air outlet 46, an electron emission control mechanism 48, and an air injection port 49.
The air pressure accumulation tank 50 includes a tank fitting port 54, a compressed air extrusion elastic film body 56, or a hard rubber ball 58.

  FIG. 1 is a cross-sectional view before injection of compressed air in a state in which a compressed air extrusion elastic film body is mounted on a color ball launcher according to the present invention. In the present invention, the expansion pressure of the compressed air accumulator tank 50 is controlled by the electromagnetic valve 40, and the outlet pressure of the compressed air discharged and ejected is controlled by the adjustment protrusion to increase the flow velocity in the lower part of the barrel, thereby loading the barrel. In this configuration, a backspin is applied to the color ball. Further, by providing the rear ejection exhaust pipe, it is possible to accurately mark the target by canceling the recoil of the firing and suppressing the barrel jumping.

  FIG. 2 is a cross-sectional view showing a state in which compressed air has started to be injected into a color ball launcher equipped with a compressed air extruded elastic film body 50. The compressed air extruding elastic film body 56 is expanded by the compressed air introduced from the air inlet 49, and is configured to reinforce and increase the ejection pressure of the compressed air ejected at the time of launch by the contraction force.

  FIG. 3 is a cross-sectional view of a state where a hard rubber ball is housed in a color ball launcher. This is a configuration in which the ejection pressure of the compressed air that is ejected at the time of firing is reinforced by the expansion force of the hard rubber ball 58 that is contracted by the atmospheric pressure in the compressed air accumulator tank 50.

  The barrel 20, electromagnetic valve 40, and compressed air accumulator tank 50 of the color ball launcher 10 are configured such that the tank fitting port 54 of the compressed air accumulator tank 50 and the electromagnetic valve fitting port 44 of the electromagnetic valve 40 are fitted together. The compressed air outlet 46 of the electromagnetic valve 40 and the compressed air inlet 26 of the barrel 20 are joined together to form a device for firing a color ball.

  The barrel 20 is a barrel portion that is formed of a long cylindrical body including a launch port 22, an adjustment protrusion 24, and a compressed air inlet 26. A launch port 22 is provided at the tip, an adjustment projection 24 is provided at the upper part of the inner periphery of the base, and a compressed air inlet 26 is provided at the base. The color ball 30 loaded in the barrel 20 is launched by the expansion pressure of the compressed air flowing in from the compressed air inlet 26. The length and the diameter of the barrel 20 can be appropriately formed in a desired size according to the pressure of the compressed air and the size of the color ball.

  The launch port 22 is a tip portion of the barrel 20, and the color ball 30 loaded in the base is pushed toward the launch port side by the expansion pressure of the compressed air, and finally the color ball 30 is moved from the launch port 22 to the barrel 20. Is fired outside. Since the structure is fired using the expansion pressure of compressed air, there is no large explosive force or heat generation, so the barrel can be made of various materials such as light alloys and resins.

  The adjustment protrusion 24 is a protrusion that protrudes from the upper part of the inner periphery of the base part of the barrel 20 toward the lower part. The adjustment protrusion 24 controls the inflow pressure of the compressed air jetted from the compressed air outlet 46 of the electromagnetic valve 40 to the compressed air inlet 26 of the barrel 20 at the upper part of the base in the barrel. By providing the adjustment protrusion 24, it is possible to increase the inflow pressure applied to the lower portion of the base portion in the barrel and cause the compressed air in the lower portion to flow out preferentially. The compressed air pushes the color ball upward toward the inner periphery of the barrel, pushes the color ball 30 toward the launch port 22 at the tip of the barrel, and fires the color ball 30 to cause backspin rotation. Due to the backspin generated by adjusting the pressure of the adjustment protrusion 24, the color ball 30 generates lift due to rotational force in the atmosphere. Therefore, it repels the force of falling while drawing a parabola by attractive force, and the trajectory is stabilized, so it is possible to ensure a longer effective range in a straight line. The adjustment protrusion 24 has a structure that can be changed in size, shape, etc. from the outside in order to be able to change the setting of the flow velocity of the compressed air depending on the specifications of the color ball to be loaded and the inner diameter and length of the barrel. It is also possible to do.

  The compressed air inlet 26 is an opening provided at the base of the barrel 20 and is configured to be joined to the compressed air outlet 46 of the electromagnetic valve 40. The compressed air flowing in from the compressed air accumulating tank 50 has a strong expansion force, passes through the electromagnetic valve 40 by releasing the on-off valve 42, and is jetted into the barrel 20 from the compressed air inlet 26 at the barrel base. The joint between the compressed air inlet 26 and the compressed air outlet 46 is sufficiently hermetically coupled so that the compressed air does not leak.

  The color ball 30 is formed of a spherical bullet in which paint is sealed in the inner part of the outer shell that is destroyed by an impact caused by a collision. The color ball 30 is loaded on the base of the barrel 20 in the preparation stage of the color ball launch. The color ball 30 marks the target object as the outer shell is destroyed by the impact of colliding with the target object, and the paint enclosed inside is scattered and adheres to the target object. The color ball 30 launched from the launch port 22 can fly accurately to the target and accurately mark by the lift by backspin. The outer shell of the color ball 30 and the paint or medicine (tearing agent) to be encapsulated may be changed appropriately according to the purpose of inspection of the structure, rescue work in the event of an accident or disaster, or riot suppression or crime prevention. Is possible. Further, the size and shape of the color ball can be changed to a desired mode according to the distance to the target, the inner diameter of the barrel, the expansion jet pressure of the accumulated air, and the like, and is not limited to this embodiment. .

  The electromagnetic valve 40 is a valve system including an electromagnetic valve fitting port 44, a compressed air outlet 46, an electron emission control mechanism 48, and an air injection port 49, and expansion of compressed air flowing from the electromagnetic valve fitting port 44. The jet power is controlled by the electronic firing control device 48, and the open / close valve 42 is opened at the time of firing to introduce compressed air from the base of the barrel 20 into the barrel lumen.

  The on-off valve 42 is a valve that controls pressure accumulation / injection of compressed air that has flowed into the electromagnetic valve 40 from the compressed air pressure accumulation tank 50, and is provided in the electronic valve 40. In addition, the electronic emission control mechanism 48 controls the opening / closing of the opening / closing valve 42 electronically. Compressed air is injected into the barrel 20 by opening the on-off valve 42, and the loaded color ball 30 is launched. By closing the on-off valve 42, the expansion force of the compressed air in the compressed air accumulator tank 50 is held in the electromagnetic valve 40. The on-off valve 42 is a valve that opens the compressed air, and at the same time is an on-off valve that includes a sealing mechanism for preventing the compressed air from flowing out into the barrel 20.

  The electromagnetic valve fitting port 44 is an opening provided at the base of the electromagnetic valve 40 and is fitted with the tank fitting port 54 of the compressed air accumulator tank 50. Since the expansion force of the compressed air from the compressed air accumulating tank 50 reaches the on-off valve 42 through the electromagnetic valve fitting port 44, the electromagnetic valve fitting port 44 is configured to be hermetically coupled to the tank fitting port 54. They are coupled by a conventional coupling method using screwing or packing.

  The compressed air outlet 46 is an opening provided at the tip of the electromagnetic valve 40 and is joined to the compressed air inlet 26 of the barrel 20. The expansion force of the compressed air from the compressed air accumulating tank 50 passes through the electromagnetic valve 40 by releasing the on-off valve 42, and enters the barrel 20 from the compressed air outlet 46 through the compressed air inlet 26 at the base of the barrel. A squirt is introduced.

The electronic emission control device 48 is a control mechanism for the opening / closing valve 42 provided in the electromagnetic valve 40, and controls the opening / closing of the opening / closing valve 42 by an electronic signal from the outside. The electron emission control device 48 is a switch using a conventional electronic circuit, and can be directly operated manually. In addition, the color ball launcher 10 is mounted on a flying body such as a drone (a floating body that can control the movement operation) or a moving body such as a truck, and a remote computer or a remote control device at hand, It is also possible to fire a color ball remotely.

  The air inlet 49 is an opening with a valve for injecting compressed air, and has a configuration provided at the base of the electromagnetic valve 40. The air inlet 49 is a conventional valve such as a check valve that is used when injecting compressed air or gas from a cylinder into a pressure accumulating tank and can hold the internal pressure after injecting compressed air. Good.

  The compressed air pressure accumulation tank 50 is composed of a pressure accumulation container capable of holding the pressure of compressed air, and has a structure including a tank fitting port 54 at the tip. It is only necessary to have rigidity for accumulating compressed air injected from the air injection port 49, and the shape and size of the tank can be appropriately changed depending on the amount of compressed air required, etc. -It can be made of various materials such as metal.

  The tank fitting port 54 is a joint provided at the tip of the compressed air accumulator tank 50 and is fitted to the electromagnetic valve fitting port 44 of the electromagnetic valve 40. Since the expansion force of the compressed air from the compressed air accumulating tank 50 reaches the opening / closing valve 42 from the tank fitting port 54 through the electromagnetic valve fitting port 44, the tank fitting port 54 is hermetically coupled to the electromagnetic valve fitting port 44.

  The compressed air extrusion elastic film body 56 is an elastic film body provided inside the compressed air accumulator tank 50, and is compressed air along the inner peripheral surface on the tank fitting port 54 side from the center of the compressed air accumulator tank 50. It is stuck to cover the pressure accumulation tank. The compressed air extrusion elastic membrane 56 has a flat thin plate shape before the compressed air is injected, and is expanded and pulled into a substantially hemispherical shape by starting the injection of the compressed air (see FIG. 2). When the compressed air injection is completed, the compressed air accumulator tank 50 is pressed to the inner wall. When the compressed air is injected by releasing the on-off valve 42, the compressed air injection elastic film 56 is configured to increase the injection pressure of the compressed air by using a contraction force that returns to a flat thin plate shape.

  The hard rubber ball 58 is a hollow elastic spherical body made of hard rubber, and is configured to be installed inside the compressed air accumulator tank 50. As the pressure in the compressed air accumulator tank 50 increases due to the injection of compressed air into the compressed air accumulator tank 50, the hard rubber ball 58 compresses and shrinks, and when the on-off valve 42 is released and the compressed air is injected, the hard rubber ball 58 is compressed. The configuration is such that the injection pressure of the compressed air is increased by utilizing the expansion force that the ball 58 returns to its original size.

  The rear ejection exhaust pipe 60 is a tubular exhaust ejection pipe provided between the on-off valve 42 of the electromagnetic valve and the compressed air outlet 46, and extends substantially from the lower end of the electromagnetic valve 40 toward the rear of the color ball launcher. This is a configuration that extends to the base of the compressed air accumulator tank 50. When the color ball is launched, the release valve 40 is released to inject the compressed air ejected from the compressed air accumulator tank into the color ball, and at the same time, the high pressure air is also ejected from the rear ejection exhaust pipe 60, thereby utilizing the law of action and reaction. This has the effect of reducing recoil due to kinetic energy during launch. By adopting the above-described configuration, the recoil of the launch is reduced, and the marking can be performed by accurately hitting the color ball against the target that is aimed.

  In the color ball launcher according to the present invention, the adjustment protrusion 24 is provided on the upper part of the inner periphery of the base of the barrel 20, thereby suppressing the pressure of the compressed air flowing from the compressed air inlet 26 at the upper part of the barrel, By spraying high-pressure compressed air at the bottom of the barrel, it is possible to apply a back spin (clockwise in FIG. 1, cross-sectional view) to the color ball 30. When the backspin is applied, the air flow in the upper part of the color ball that is launched from the barrel and flies faster than the lower part, and lift is generated in the launched color ball 30 due to the difference in atmospheric pressure between the upper and lower sides of the ball. As a result, it is possible to delay the time when the color ball starts to fall in a parabolic shape due to the attractive force, so that the flight distance can be extended while maintaining the launch angle, and thus the effective range of the color ball can be extended.

  By adopting the above-described configuration, the color ball 30 with lift generated by the Magnus effect flies while maintaining a straight trajectory after launch, so even a target at a certain distance can be reliably positioned at the position aligned with the sighting device. It is possible to land on. In addition, since the flight distance is extended, it is possible to land on the target with an amount of compressed air required to fly an arbitrary distance, which is smaller than the conventional amount. Compared with the conventional structure that controls the pressure of the compressed air injected to the upper and lower parts of the color ball 30 and applies the backspin by the difference in the jet pressure, which is applied to the protrusion and packing. Thus, it is possible to prevent a drop in the initial firing speed. Further, in the structure according to the present invention, since wear such as protrusions and packing does not occur, it is possible to accurately apply backspin to the color ball over a long period of time.

  Since the effective range can be extended while maintaining a straight trajectory, it is possible to accurately mark the faulty part detected by inspection etc. from a distant place and maintain a continuously visible state. It is possible. In addition, a color ball launcher is installed in a drone or other flying object, and when searching in a place where humans cannot easily enter during a disaster, it is possible to accurately mark according to the aim that matches the target I have to.

Since the color ball launching apparatus according to the present invention provides the same effect as the recoilless gun by providing the rear jet exhaust pipe 60, the color ball can be accurately fired even in an environment without a sturdy gun mount or the like. It became possible to do. Because it is a structure that makes it possible to suppress the reaction to an extremely small level, even a lightweight flying object (such as a drone) that is extremely unstable and difficult to generate a large reaction will be affected by the impact of the launch. This makes it possible to perform marking accurately without being subjected to. In addition, by reducing the recoil, it is possible to construct a turret with only light and simple equipment and launch the target marking work when installing only the color ball launching mechanism on a moving body such as a truck. It has become. Of course, the rear ejection exhaust pipe 60 can be removed or the ejection amount can be appropriately adjusted according to the assumed range length and the required accuracy of hitting.

  Further, by embedding the compressed air extruding elastic film 56 or the hard rubber ball 58 inside the compressed air accumulating tank 50, when the compressed air is injected by utilizing the elastic action of the resin due to the rise or fall of the tank internal pressure. It is possible to increase the jet pressure. By increasing the ejection pressure, it is possible to ensure a longer flight distance with the same amount of compressed air as in the prior art.

  By using a phosphorescent paint or a self-luminous paint as the paint encapsulated in the color ball, it becomes possible to keep the marking part clearly visible at night or in a dark place. It is also possible to make a teardrop that sprays and diffuses a non-lethal tear agent that can be neutralized and removed over time or by natural degradation by enclosing a tear agent in a color ball and firing it. . It is possible to prevent crimes by suppressing the mob when a riot occurs and by spraying tears on those who are planning to commit crimes. The color ball launcher mounted on the drone according to the present invention can launch various types of color ball bullets from a remote location, and can secure a stable long flight distance. Because it is possible, it is possible to perform riot suppression and crime deterrence safely without approaching the mob and criminal.
