Description

Technical Field

[0001] The present invention relates to a gas gun, and more particularly to a gas gun driven by detonation of reactive gases, belonging to the technical field of gun body equipment. Background Art

[0002] Experimental devices for launching various projectiles / loads are not only widely needed in the research of weapon science and technology and other majors, but also have many experimental needs for launching projectiles / loads in professional fields such as aviation, aerospace, high-pressure physics, disaster prevention and mitigation. Currently, there are mainly two types of the above experimental devices. One type is modified based on traditional guns, and the other type is driven by high-pressure gases (mostly N2). Although the driving ability of the former is much higher than that of the latter, since gun firing involves pyrotechnics, professional personnel are required for operation, and professional pyrotechnics transportation and storage conditions are needed. Most universities, research institutes and other units do not have the above conditions.

[0003] In the tasks of road opening and traffic maintenance by China's emergency rescue and relief forces, it is necessary to launch kinetic energy fragmentation projectiles to quickly destroy obstacles such as dangerous rocks and blocking stones; launch blasting projectiles to induce controllable avalanches and landslides to eliminate road safety hazards; launch various fire extinguishing projectiles and chemical agent projectiles for forest fire fighting, high-rise building fire fighting and hazardous chemical disposal; launch pilot cables for bridge and power line construction, etc. Although launching devices are required in the above various scenarios, due to relevant regulations, the emergency rescue and relief forces cannot be equipped with traditional guns.

[0004] H2, CH4 and O2 are all common industrial gases, which are transported and stored in steel cylinders with a working pressure of 15 MPa and are easy to obtain. The reactive gas gun is an experimental device that uses the above common industrial gases as working media, and its launching ability is equivalent to that of traditional guns; when injecting gas using a steel cylinder, the high-pressure gas pipeline has corresponding interface standards and valves, which is convenient to use. Therefore, this type of experimental device has a wide application prospect and can fill the gap left by the inability to use traditional guns. However, most of the gas guns in the existing technology remain in the experimental stage, and there is no reusable gas gun that can be actually used. Summary of the Invention

Detailed Embodiments

[0038] The following will further elaborate on the present invention in detail in conjunction with the drawings and embodiments.

[0039] Embodiment 1:

[0040] This embodiment provides a gas gun driven by the detonation of reaction gas, which has a simple structure, can realize the repeated loading of the projectile, is applicable not only to various launch experiment occasions, but also to emergency rescue tasks such as road clearance and traffic maintenance, is easy to operate, safe to use; and has a low launch cost.

[0041] As Figure 1 and Figure 2 shown, the gas gun includes: a detonation drive assembly, a gun tube assembly and a gun body support assembly. Among them, the detonation drive assembly and the gun tube assembly are coaxially and hermetically fixed and supported on the gun body support assembly.

[0042] The detonation drive assembly is used to generate detonation driving force. The detonation drive assembly includes: a reaction chamber 1-1, an ignition device 1-2 and a transition ring 1-3; for the convenience of description, let the end of the detonation drive assembly connected to the gun tube assembly be its front end, and the other end be its rear end; the reaction chamber 1-1 is a gas chamber cylinder with openings at both axial ends, and its internal space is successively an equal-diameter section and a contraction section extending along the axis from the rear to the front, wherein the large end of the contraction section is connected to the equal-diameter section, and the diameter of the large end of the contraction section is the same as the diameter of the equal-diameter section; setting the contraction section can increase the base pressure of the projectile and increase the maximum launch speed.

[0043] The rear end of the reaction chamber 1-1 is connected to the ignition device 1-2 extending into the reaction chamber 1-1 by a threaded seal; the front end is coaxially connected to the transition ring 1-3, and the seal in front of the reaction chamber 1-1 is achieved through the transition ring 1-3 and the projectile body embedded in the transition ring 1-3.

[0044] Before launch, the ignition device 1-2 is screwed into the rear end of the reaction chamber 1-1 with a hex wrench; the front end of the reaction chamber 1-1 is inserted into the transition ring 1-3 nested with the projectile body to seal the internal space of the reaction chamber 1-1. The reaction chamber 1-1 is connected to the gas storage cylinder through a standard interface, and reaction gas is filled into the reaction chamber 1-1 through the gas storage cylinder. For example, a set amount of hydrogen and oxygen are filled in sequence as the reaction gas. During launch, the ignition device 1-2 is activated, and the reaction gas (such as hydrogen-oxygen gas) inside the reaction chamber 1-1 is ignited by the high-temperature plasma, stimulating the reaction gas to quickly undergo a chemical reaction. The temperature and pressure inside the reaction chamber 1-1 rise sharply, forming a gas-phase detonation. In a very short time, the detonation wave and detonation products reach the bottom of the projectile body, and the projectile body is separated from the transition ring 1-3 under the action of detonation drive and enters the launch tube 2-1 of the gun barrel assembly. By using this kind of detonation drive assembly, the firing rate can be controlled by adjusting the pressure of the initial reaction gas (i.e., the gas injection pressure). Experiments show that when the detonation reaction chamber is filled with gas using a 15 MPa industrial gas cylinder through a standard interface and CH4 is used as the reaction gas working medium, the initial gas injection pressure is about 5 MPa, and the firing ability equivalent to that of a cannon of the same caliber can be obtained, with a low firing cost.

[0045] The gun barrel assembly includes: a launch tube 2-1, a hydraulic clamping assembly 2-2, a muzzle brake 2-3, and a set of Belleville springs 2-4; among them, the launch tube 2-1 is an equal-diameter tube body with openings at both axial ends, used to accommodate and launch the projectile body. The outer circumference of the rear end of the launch tube 2-1 (the end connected to the detonation drive assembly) is sleeved with the hydraulic clamping assembly 2-2. The launch tube 2-1 is coaxially fixedly connected to the front end of the reaction chamber 1-1 through the hydraulic clamping assembly 2-2 by a thread, and the compression seal at the connection is ensured. Specifically:

[0046] One end of the transition ring 1-3 extends into the interior of the reaction chamber 1-1 (abutting against the shoulder at the end of the reaction chamber 1-1), and the other end extends into the interior of the launch tube 2-1, where the end of the launch tube 2-1 abuts against the shoulder on the outer circumferential surface of the transition ring 1-3; thus, the coaxial docking of the central holes of the reaction chamber 1-1 and the launch tube 2-1 is achieved through the transition ring 1-3. The hydraulic pressing assembly 2-2 includes a cylinder block, a piston, and an end cap; an external thread is provided on the outer circumference at the front end of the reaction chamber 1-1, and one end of the cylinder block is threadedly engaged with the external thread on the outer circumference at the front end of the reaction chamber 1-1 through an internal thread; the other end is sealed by an end cap sleeved on the outer circumference of the launch tube 2-1, and the end cap is fixedly connected to the launch tube 2-1 through a fastener; the piston is sleeved on the outer circumferential surface of the launch tube 2-1 located inside the cylinder block, and is in sliding fit with the outer circumferential surface of the launch tube 2-1 and the inner circumferential surface of the cylinder block, and can move axially along the launch tube 2-1; and a shoulder is machined on the outer circumferential surface of the launch tube 2-1 located inside the cylinder block, and this shoulder is located between the piston and the rear end face of the launch tube 2-1; let the annular cavity between the piston and the end cap inside the cylinder block be cavity A, and the annular cavity between the piston and the shoulder be cavity B; when oil is filled into cavity A, the piston is pushed towards the shoulder end, and then the oil in cavity B is used to push the launch tube 2-1 to press the transition ring 1-3, realizing the pressing and sealing at this connection.

[0047] A transition ring 1-3 is designed between the launch tube 2-1 and the reaction chamber 1-1. The transition ring 1-3 is a cylindrical ring with a variable diameter (i.e., having a shoulder) made of high-strength steel. The projectile is loaded inside the transition ring 1-3 through a high-pressure polyethylene cylindrical ring; the transition ring 1-3 can seal high-pressure reaction gases and at the same time can serve as the bottom push for launching the projectile. The bottom of the projectile is the area where the high-temperature reaction products ablate the most severely. The transition ring 1-3 is replaceable, which can relieve the ablation of the launch tube 2-1 and improve the service life of the launch tube 2-1.

[0048] The front end of the launch tube 2-1 is connected to the muzzle brake 2-3. The muzzle brake 2-3 is a flat structure with a cavity, used to remove the sabot that wraps the projectile. A plurality of disc springs form a disc spring group 2-4 sleeved on the outer circumference of the middle and rear parts of the launch tube 2-1, used to absorb energy to reduce the vibration intensity of the gun body during the projectile launch; among them, the disc spring group 2-4 is fixed on the launch tube through a groove; in this example, two disc spring groups 2-4 are provided, and the two disc spring groups 2-4 are separated by a support ring fixedly connected to the outer circumferential surface of the launch tube 2-1, that is, one end of the two disc spring groups 2-4 abuts against the support ring, and the other ends respectively abut against the gun body support assemblies arranged at the corresponding positions; when the launch tube recoils, the support ring compresses the disc spring group 2-4 to bear the force.

[0049] During launch, the projectile is driven by the detonation wave and detonation products, obtaining a large initial acceleration, separating from the transition ring 1-3 and entering the launch tube 2-1. Due to the consumption of reaction gas, the detonation wave loses its self-sustaining chemical reaction and propagates back and forth as a shock wave between the bottom of the reaction chamber 1-1 and the bottom of the projectile. The projectile accelerates forward in the launch tube 2-1 with an intermittently changing acceleration under the driving action of the shock wave and detonation products. At the moment when the projectile exits the muzzle, the muzzle brake 2-3 intercepts the sabot that wraps the projectile, and the projectile is not affected and continues to move forward until it hits the target object. During the launch process of the projectile, the butterfly spring group 2-4 nested around the middle and rear parts of the launch tube 2-1 will undergo elastic deformation to absorb energy, thereby reducing the vibration intensity of the gun body.

[0050] The gun body support assembly is used to support the detonation drive assembly and the gun barrel assembly; the gun body support assembly includes: the reaction chamber support 3-1, the launch tube support 3-2, the guide rail 3-3 and the base 3-4; the reaction chamber support 3-1 and the launch tube support 3-2 are respectively arranged at two opposite ends of the base 3-4, wherein the reaction chamber support 3-1 is in rolling cooperation with the guide rail 3-3 arranged on the base 3-4 through rollers; multiple (two in this example) clamps (formed by docking two semi-circular rings) for clamping the reaction chamber 1-1 are arranged on the reaction chamber support 3-1. The launch tube support 3-2 is a clamp supported by a support seat, and there can be multiple (two in this example) launch tube supports 3-2, which are arranged at both ends of the two butterfly springs 2-4; that is, one end of the two butterfly spring group rings 2-4 abuts against the support ring, and the other ends respectively abut against the launch tube supports 3-2 arranged at the corresponding positions. Before launch, the reaction chamber 1-1 is fixedly connected to the reaction chamber support 3-1, and the launch tube 2-1 is fixedly connected to the launch tube support 3-2, thereby playing a supporting role for the detonation drive assembly and the gun barrel assembly. The axial position of the reaction chamber 1-1 is adjusted by the movement of the reaction chamber support 3-1 on the guide rail 3-3 to disassemble and assemble the reaction chamber 1-1 for convenient loading of the projectile.

[0051] In addition to being used in various launch experiment occasions, this gas gun can also launch kinetic energy fragmentation projectiles during road clearance and traffic maintenance tasks to quickly destroy obstacles such as dangerous rocks and blocking stones; launch blasting projectiles to induce controllable avalanches and landslides to eliminate road safety hazards; launch various fire extinguishing projectiles and chemical agent projectiles for forest fire fighting, high-rise building fire fighting and hazardous chemical disposal; launch pilot cables for various scenarios such as bridge and power line construction.

[0052] Embodiment 2:

[0053] On the basis of the above Embodiment 1, a gun carriage is further set for the gas gun in Embodiment 1. In this example, the gun carriage adopts a towed gun truck, and this gas gun is fixed on the towed gun truck through the base 3-4.

[0054] AsFigure 3 As shown in the figure, the towed gun carriage includes: a vehicle frame 4-1 and a traveling mechanism arranged below the vehicle frame 4-1; the above gas gun is fixed on the vehicle frame 4-1 through a base 3-4; at the same time, at one end of the vehicle frame 4-1, in this example, a towing ring 4-4 is arranged below the rear end face of the vehicle frame 4-1, and two wheels are arranged at the front end of the bottom of the vehicle frame 4-1 as the traveling mechanism (not shown in the figure); thus, a towed gas reaction gun is formed. By connecting a towing mechanism (such as a towing rope) to the towing ring 4-4, the towing of the towed gun carriage can be realized.

[0055] Considering that the experiment scenario is generally mainly flat shooting, the towed gas gun cancels the elevation mechanism and the traverse mechanism, and the adjustment of the height and elevation angle (i.e., the pitch angle) of the gas gun is realized by arranging legs with telescopic functions below the vehicle frame 4-1. Specifically, four legs with telescopic functions are distributed in a rectangle below the vehicle frame 4-1, that is, two legs are arranged at each of the front and rear ends below the vehicle frame 4-1. In this example, four hydraulic supports 4-3 are distributed in a rectangle below the vehicle frame 4-1 as the legs. The hydraulic support 4-3 is a hydraulic cylinder, and its telescopic end is used as the ground-supporting end, and the cylinder body end is hinged to the vehicle frame 4-1. And the ends of the ground-supporting ends of the two hydraulic supports 4-3 at the front end are connected by a long strip-shaped base, and the ends of the ground-supporting ends of the two hydraulic supports 4-3 at the rear end are connected by a long strip-shaped base; arranging the long strip-shaped base can increase the area of the hydraulic support 4-3 in contact with the ground, which helps to provide the supporting force.

[0056] When not in firing, the ground-supporting ends of the hydraulic supports 4-3 are retracted and do not contact the ground. At this time, the traveling mechanism contacts the ground, and the traveling function can be realized; when firing is required, first extend the ground-supporting ends of the two hydraulic supports 4-3 to make the long strip-shaped base contact the ground; then, by controlling the extension length of the ground-supporting ends of the two hydraulic supports 4-3, the height and pitch angle of the gas gun supported on the vehicle frame 4-1 can be adjusted.

[0057] Although the present invention has been described in detail with general descriptions and specific embodiments above, based on the present invention, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.
