Description

Technical Field

[0001] This invention belongs to the field of projectile launching devices, and in particular relates to a launching device. Background Technology

[0002] As a common and relatively important type of launching device, the combustion light gas gun has advantages such as strong launching capability, high initial burst velocity, good reliability, and simple structure. It is widely used in fields such as high-speed collision, closed detonation, internal ballistic calculation, and experimental research on object launch.

[0003] The combustion gas cannon mainly consists of a high-pressure chamber, a valve, a piston, a pressure guide tube, and a launch tube. The high-pressure chamber is connected to the pressure guide tube, and the piston slides within the tube. The projectile is located inside the launch tube. High-pressure gas is generated within the high-pressure chamber. The valve controls the gas pressure in the high-pressure chamber and directs the high-pressure gas through the pressure guide tube, pushing the piston to slide within the tube and propelling the projectile forward within the launch tube. The projectile and piston then exit the barrel together. This mechanism of the gas cannon has the drawback of a long preparation time for re-firing, and the piston cannot be reused, resulting in high material consumption.

[0004] In summary, the shortcomings of existing combustion light gas cannons are: the preparation time for the light gas cannon to fire again is relatively long, and the piston will cause high material consumption because it cannot be reused. Summary of the Invention

[0060] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0061] Please see Figures 1 to 5 It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and to facilitate understanding. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0062] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0063] Please see Figures 1 to 5 The present invention provides a launching device, the launching device comprising:

[0064] Cylinder body 101, wherein a pneumatic chamber 102 is provided inside the cylinder body 101;

[0065] Air inlet 103 and air outlet 104, both of which are provided on cylinder block 101;

[0066] In this embodiment, high-pressure gas can be directly introduced into the pressure chamber 102 through the air inlet 103, or an ignitable substance can be introduced into the pressure chamber 102 through the air inlet 103 and ignited in the pressure chamber 102 to generate high-pressure gas; the launching tube is disposed on the cylinder body 101, and the launching tube is connected to the pressure chamber 102 through the air outlet 104. The projectile 105 is placed in the launching tube, and the gap between the outer wall of the projectile 105 and the inner wall of the launching tube is zero;

[0067] The opening and closing valve core 201 is located inside the cylinder body 101 and is slidably installed inside the cylinder body 101. The opening and closing valve core 201 opens and closes the air outlet 104, and the sliding direction of the opening and closing valve core 201 is parallel to the axial direction of the launching tube.

[0068] An opening and closing assembly includes an unlocking rod 401, which is slidably installed inside the launching tube. The sliding direction of the unlocking rod 401 is parallel to the axial direction of the launching tube. The unlocking rod 401 slides and pushes the opening and closing valve core 201 to open the air outlet 104.

[0069] The unlocking rod 401 is in contact with the opening and closing valve core 201. The unlocking rod 401 slides and can push the opening and closing valve core 201 to move, thereby opening the air outlet 104.

[0070] When the air pressure in the air chamber 102 is high, the unlocking rod 401 slides toward the opening and closing valve core 201 and pushes the opening and closing valve core 201 to open the air outlet 104. The high-pressure gas enters the launching tube through the air outlet 104 and pushes the projectile 105 to move out of the launching tube, thereby launching the projectile 105 out of the launching tube.

[0071] In this embodiment, please refer to Figures 1 to 5 An ignition component 106 is fixedly installed inside the cylinder 101. The ignition component 106 is not limited here. Its main purpose is to ignite the fuel in the air pressure chamber 102. The ignition component 106 can be a spark plug, igniter, etc.

[0072] The cylinder 101 contains vaporizable and combustible fuel. The type of fuel is not limited here, but it is mainly fuel that can be vaporized and then fed into the pressure chamber 102 for combustion. The vaporization here can be that the fuel itself is a gas and is directly fed into the pressure chamber 102 for combustion, or the fuel is a liquid that can be vaporized into a gas and fed into the pressure chamber 102 for combustion, or the fuel is a solid that can be vaporized into a gas and fed into the pressure chamber 102 for combustion. The fuel here can be diesel, gasoline, natural gas, liquefied petroleum gas, dimethyl ether, methane, methanol, hydrogen, etc.

[0073] After the fuel is introduced into the pneumatic chamber 102 of the cylinder block 101 through the air intake port 103, the ignition component 106 is activated to ignite the fuel in the pneumatic chamber 102. When the fuel burns, the air pressure in the pneumatic chamber 102 is increased. The unlocking push rod 401 slides and pushes the opening and closing valve core 201, thereby opening the air outlet 104. The high-pressure gas in the pneumatic chamber 102 enters the launch tube and pushes the projectile 105 out of the launch tube.

[0074] In this embodiment, the air inlet 103 can also be connected to the fuel storage device through a pipe, and a one-way valve can be installed on the pipe. The one-way valve can allow fuel to enter the pressure chamber 102 and prevent the high-pressure gas in the pressure chamber 102 from leaking out of the pipe, thereby ensuring that the pressure in the pressure chamber 102 does not decrease.

[0075] In this embodiment, please refer to Figures 1 to 5The launch tube includes a Laval nozzle section 301 and a projectile launch tube section 302;

[0076] One end of the Laval nozzle section 301 is fixedly connected to the cylinder body 101, and the other end of the Laval nozzle section 301 is fixedly connected to the projectile launching tube section 302. The axes of the Laval nozzle section 301 and the projectile launching tube section 302 coincide. The Laval nozzle section 301 connects the exhaust port 104 to the projectile launching tube section 302. The projectile 105 is placed inside the projectile launching tube section 302, and the gap between the outer wall of the projectile 105 and the inner wall of the projectile launching tube section 302 is zero.

[0077] One end of the Laval nozzle section 301 connected to the cylinder body 101 is the starting part of the Laval nozzle section 301, and the other end of the Laval nozzle section 301 is the airflow acceleration end of the Laval nozzle section 301. The center of the Laval nozzle section 301 is a through hole, one end of which is connected to the air outlet 104, and the other end of which is connected to the projectile launching tube section 302. The diameter of the middle part of the through hole is smaller than the diameter of the airflow acceleration end of the Laval nozzle section 301. The airflow acceleration end of the Laval nozzle section 301 is located on the side closer to the projectile launching tube section 302.

[0078] The unlocking rod 401 is slidably installed inside the Laval nozzle section 301.

[0079] The high-pressure gas inside the cylinder 101 is ejected through the exhaust port 104 and enters the tail of the projectile 105 through the Laval nozzle section 301. The gas velocity passing through the Laval nozzle section 301 will increase, thereby increasing the launch speed of the projectile 105.

[0080] In this embodiment, please refer to Figures 1 to 5 The vent 104 is conical, and the axis of the vent 104 coincides with the axis of the launching tube.

[0081] The smaller diameter end of the conical vent 104 is located on the side closer to the launch tube;

[0082] The outer wall of the opening and closing valve core 201 is conical, and the outer wall of the opening and closing valve core 201 is in contact with the side wall of the air outlet 104.

[0083] By making both the vent 104 and the outer wall of the valve core 201 conical, after the air pressure in the cylinder 101 increases, an outward force can be applied to the valve core 201, thereby enabling the valve core 201 to reliably close the vent 104.

[0084] In this embodiment, the conical air outlet 104 can also be extended into the Laval nozzle section 301, that is, the air outlet 104 is located between the two end faces of the Laval nozzle section 301. The distance between the starting part of the Laval nozzle section 301 and the air outlet 104 can be set to 30-40mm, so as to construct an expansion cavity at the front end of the air outlet 104, so that the gas in the cylinder 101 can flow more easily through the Laval nozzle section 301 for acceleration.

[0085] In this embodiment, please refer to Figures 1 to 5 The launching device further includes a sliding guide assembly for guiding the sliding of the opening and closing valve core 201, the sliding guide assembly including a guide slide rod 202 and a spring 203;

[0086] The guide slide rod 202 is slidably installed inside the cylinder body 101. The sliding direction of the guide slide rod 202 is parallel to the axial direction of the launching tube. One end of the guide slide rod 202 is fixedly connected to the opening and closing valve core 201. The spring 203 is sleeved on the guide slide rod 202. One end of the spring 203 is fixedly connected to the guide slide rod 202, and the other end of the spring 203 is fixedly connected to the cylinder body 101.

[0087] After the opening and closing valve core 201 opens the air outlet 104, the spring 203 can push the opening and closing valve core 201 back to its original position, thereby making the air pressure chamber 102 re-sealed.

[0088] In this embodiment, please refer to Figures 1 to 5 The opening and closing assembly includes an air guide pipe 402, a first piston cylinder 403, a first piston 404, a first slide rod 405, an automatic valve 406, a vent hole 407, a second piston cylinder 408, a second piston 409, a second slide rod 410, a third piston cylinder 411, a third piston 412, a third slide rod 413, and a valve core opening and holding module;

[0089] The first piston cylinder 403 is located outside the cylinder body 101, and the first piston 404 is slidably installed inside the first piston cylinder 403. The first piston 404 divides the first piston cylinder 403 into a first chamber and a second chamber.

[0090] One end of the air guide tube 402 is connected to the air pressure chamber 102, and the other end of the air guide tube 402 is connected to the first chamber. The automatic valve 406 is installed on the air guide tube 402. When the air pressure in the air pressure chamber 102 reaches its maximum, the automatic valve 406 opens.

[0091] The vent 407 is located on the side wall of the first piston cylinder 403;

[0092] When the automatic valve 406 is not open, the vent hole 407 is located between the two end faces of the first piston 404. That is, when the gas in the pressure chamber 102 does not enter the first piston cylinder 403 through the air guide pipe 402, the first piston 404 is in its initial state in the first piston cylinder 403 and blocks the vent hole 407. This prevents the gas in the first piston cylinder 403 from being directly discharged through the vent hole 407 before the vent hole 104 is opened. After the automatic valve 406 is opened (that is, after the gas in the pressure chamber 102 enters the first piston cylinder 403 through the air guide pipe 402), the first piston 404 slides and the first chamber communicates with the external space through the vent hole 407.

[0093] The automatic valve 406 is not limited here. It mainly opens automatically after the air pressure in the air chamber 102 reaches a certain level, so that the first piston 404 can slide in the first piston cylinder 403. The automatic valve 406 can be a pressure reducing valve, a safety valve, a pressure relief valve, or a one-way valve that can only open when a certain pressure is reached. The one-way valve includes a valve body 601, a first flow passage 602, a slider 603, a second flow passage 604, a one-way valve core 605, a one-way valve spring 606, and an annular groove 607.

[0094] The valve body 601 is mounted on the air guide pipe 402. A first flow-through hole 602 is formed within the valve body 601. An annular groove 607 is formed on the side wall of the first flow-through hole 602, the axis of which coincides with the axis of the first flow-through hole 602. A slider 603 is slidably mounted within the annular groove 607 and slides along the axis of the annular groove 607. A one-way valve core 605 is fixedly mounted on the slider 603, located between the liquid inlet of the first flow-through hole 602 and the slider 603. The valve core 605 opens and closes the first flow passage 602. The slider 603 has a second flow passage 604 that penetrates its left and right side walls. One end of the one-way valve spring 606 is fixedly connected to the slider 603, and the other end of the one-way valve spring 606 is fixedly connected to the annular groove 607. The one-way valve spring 606 is located between the liquid outlet of the first flow passage 602 and the slider 603. Gas passes through the liquid inlet of the first flow passage 602 and pushes the one-way valve core 605 toward the liquid outlet of the first flow passage 602. At this time, gas can pass through the second flow passage 604, thereby realizing the opening of the one-way valve.

[0095] One end of the first slide rod 405 is located in the second chamber and is fixedly connected to the first piston 404. The other end of the first slide rod 405 slides through the first piston cylinder 403 and extends out of the first piston cylinder 403. The sliding direction of the first slide rod 405 is parallel to the sliding direction of the first piston 404.

[0096] The second piston cylinder 408 is also located outside the cylinder body 101, and the second piston 409 is slidably installed inside the second piston cylinder 408. The sliding direction of the second piston 409 is parallel to the sliding direction of the first piston 404.

[0097] One end of the second slide rod 410 is located inside the second piston cylinder 408 and is fixedly connected to the second piston 409. The other end of the second slide rod 410 slides through the second piston cylinder 408 and extends out of the second piston cylinder 408. The sliding direction of the second slide rod 410 is parallel to the sliding direction of the second piston 409.

[0098] The third piston cylinder 411 is located inside the launch tube. The third piston cylinder 411 may be located inside the Laval nozzle section 301. The third piston cylinder 411 is connected to the second piston cylinder 408 through a connecting pipe. The third piston 412 is slidably installed inside the third piston cylinder 411. The sliding direction of the third piston 412 is parallel to the sliding direction of the unlocking push rod 401.

[0099] One end of the third slide rod 413 is fixedly installed on the third piston 412, and the other end of the third slide rod 413 slides through the third piston cylinder 411 and is fixedly connected to the unlocking top rod 401. The sliding direction of the third slide rod 413 is parallel to the sliding direction of the third piston 412.

[0100] The first slide bar 405 is connected to the second slide bar 410 through a valve core opening and holding module, which is used to keep the air outlet 104 in the open state.

[0101] Gas in the pressure chamber 102 enters the first piston cylinder 403 through the air guide pipe 402, pushing the first piston 404 to slide to the right, thereby pushing the first slide rod 405 to extend outward. This, in turn, pushes the second slide rod 410 to slide to the right through the valve core opening and holding module, and pushes the second piston 409 to slide, thereby pushing the third piston 412 to slide. This, in turn, drives the unlocking push rod 401 to move through the third slide rod 413, thereby moving the opening and closing valve core 201 into the pressure chamber 102, thus opening the air outlet 104. The high-pressure gas in the pressure chamber 102 is ejected through the air outlet 104 and passes through the Laval nozzle section 301 in sequence, entering the projectile launching tube section 302, thereby launching the projectile 105 from the projectile launching tube section 302.

[0102] In this embodiment, please refer to Figures 1 to 5 The valve core opening and holding module includes a support frame 501, a first spring 502, a second spring 503, a push block 504, a first L-shaped locking hook 505, and a second L-shaped locking hook 506.

[0103] The pusher block 504 is fixedly installed on the extended section of the first piston cylinder 403 of the first slide rod 405;

[0104] The first L-shaped locking hook 505 includes a horizontal block and a vertical block. The horizontal block and the vertical block of the first L-shaped locking hook are fixedly connected. The horizontal block of the first L-shaped locking hook is rotatably mounted on a support frame 501. The support frame 501 can be directly fixedly mounted on the cylinder body 101, or it can be set separately and not fixedly mounted on the cylinder body 101 (this method is not shown). The rotation axis of the horizontal block of the first L-shaped locking hook is perpendicular to the sliding direction of the first slide rod 405. The rotation axis of the horizontal block of the first L-shaped locking hook is located between the push block 504 and the vertical block of the first L-shaped locking hook. The horizontal block of the first L-shaped locking hook is in contact with the push block 504.

[0105] The intersection point of the transverse block of the first L-shaped locking hook and the push block 504 is the first point. The minimum distance between the first point and the center line of the first slide rod 405 is a. The minimum distance between the rotation axis of the transverse block of the first L-shaped locking hook and the center line of the first slide rod 405 is b. a≠b, that is, when the first slide rod 405 extends outward and drives the push block 504 to move to the right, it can push the transverse block of the first L-shaped locking hook to rotate.

[0106] One end of the first spring 502 is fixedly connected to the support frame 501, and the other end of the first spring 502 is fixedly connected to the transverse block of the first L-shaped locking hook;

[0107] The intersection of the first spring 502 and the transverse block of the first L-shaped lock hook is the second point. The first point can be located above the rotation axis of the transverse block of the first L-shaped lock hook, and the first point and the second point are located on the left and right sides of the rotation axis of the transverse block of the first L-shaped lock hook, respectively.

[0108] The second spring 503 is located inside the second piston cylinder 408. One end of the second spring 503 is fixedly connected to the second piston 409, and the other end of the second spring 503 is fixedly connected to the second piston cylinder 408.

[0109] The second spring 503 can be located between the second piston 409 and the second L-shaped locking hook 506. When the first L-shaped locking hook 505 and the second L-shaped locking hook 506 are locked, the second spring 503 is in a compressed state. The second spring 503 can also be located on the side of the second piston 409 away from the second L-shaped locking hook 506. When the first L-shaped locking hook 505 and the second L-shaped locking hook 506 are locked, the second spring 503 is in a stretched state.

[0110] The second L-shaped locking hook 506 includes a horizontal plate and a vertical plate. One end of the horizontal plate of the second L-shaped locking hook is fixedly connected to the second slide bar 410, and the other end of the horizontal plate of the second L-shaped locking hook is fixedly connected to the vertical plate of the second L-shaped locking hook.

[0111] The end face of the vertical block of the first L-shaped locking hook near the push block 504 is the first locking surface, and the end face of the vertical plate of the second L-shaped locking hook near the second piston cylinder 408 is the second locking surface. The first locking surface and the second locking surface are in contact.

[0112] The opposite surface of the first locking surface on the vertical block of the first L-shaped locking hook is a guide slope.

[0113] When the vertical plate of the second L-shaped locking hook moves toward the vertical block of the first L-shaped locking hook, the vertical plate of the second L-shaped locking hook comes into contact with the guide slope and pushes the horizontal block of the first L-shaped locking hook to rotate.

[0114] The first slide rod 405 extends outward, thereby driving the push block 504 to move to the right, which in turn pushes the first L-shaped locking hook 505 to rotate clockwise and compresses the first spring 502. When the first L-shaped locking hook 505 rotates clockwise, it will unlock with the second L-shaped locking hook 506. The second L-shaped locking hook 506, driven by the second spring 503, will drive the second slide rod 410 to move to the right, thereby driving the second piston 409 to slide to the right, which in turn pushes the third piston 412 to slide. This, in turn, drives the unlocking push rod 401 to move into the air pressure chamber 102 through the third slide rod 413, thereby pushing the opening and closing valve core 201 to open the air outlet 104. Moreover, due to the presence of the second spring 503, the opening and closing valve core 201 will keep the air outlet 104 open, so that the gas in the air pressure chamber 102 will be fully ejected from the cylinder 101, thereby ensuring the firing speed of the projectile 105.

[0115] When the projectile 105 needs to be fired again, the second L-shaped locking hook 506 is held and moved toward the first L-shaped locking hook 505, so that the second spring 503 is recharged and the second L-shaped locking hook 506 is hooked with the first L-shaped locking hook 505 and locked again.

[0116] When the first piston 404 slides to the point where the first chamber communicates with the external space through the vent 407, the sliding displacement of the first piston 404 is m; when the first L-shaped locking hook 505 rotates to unlock with the second L-shaped locking hook 506, the sliding displacement of the first piston 404 is n, where m ≥ n;

[0117] When the first piston 404 slides and unlocks the first L-shaped locking hook 505 and the second L-shaped locking hook 506, it will compress the first spring 502. At the same time, the gas in the air pressure chamber 102 flows out through the air outlet 104. Meanwhile, the first piston 404 continues to move to the right and exposes the vent hole 407. At this time, the first spring 502 is in the maximum compression state, so that the first chamber is connected to the external space through the vent hole 407, thereby releasing the air pressure in the first piston cylinder 403. The first spring 502 resets and drives the first piston 404 to move to the left to reset.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
