Description

Technical Field

[0001] The invention relates to the technical field of simulated anti-tank mines, and in particular to the optimization of a simulated anti-tank mine anti-misstart technology. Background Art

[0002] Anti-tank mines are mines used to damage or destroy vehicles such as tanks and armored personnel carriers. At present, troops generally use simulated mines instead of mines in teaching and training to avoid casualties of personnel and vehicles; the existing simulated anti-tank mines for teaching are usually deployed by airdrop, such as using drones to carry multiple simulated anti-tank mines for aerial delivery. When the drone flies to the predetermined minefield coordinates, the simulated anti-tank mines are thrown to the ground through an electromagnetic release device. However, this deployment method has the following technical defects: 1. During the drone drop process, the simulated anti-tank mine falls at a high speed due to the acceleration of gravity, and is affected by factors such as air resistance and wind direction, so the posture of the mine is uncontrollable when it touches the ground. The trigger end of traditional simulated anti-tank mines (such as pressure sensors, mechanical trigger arms, etc.) is usually exposed outside the shell to achieve rapid response. When the trigger end first touches the ground at an inclined angle or in a vertical direction, the instantaneous impact force it bears may exceed the preset trigger threshold, causing the mine to be activated by mistake; and the simulated anti-tank mine that is activated by mistake will send out an audible and visual alarm signal or release a smoke mark in advance, which will not only reduce the effectiveness of the minefield, but also expose the deployment location information. In actual combat training, this non-tactical trigger will reduce the authenticity of the training. Summary of the invention

[0003] Therefore, in view of the above-mentioned problems, the present invention proposes a simulated anti-tank mine that can prevent false activation, so as to avoid reducing the authenticity of training due to non-tactical triggering.

[0004] The present invention is achieved through the following technical solutions.

[0005] A simulated anti-tank mine, comprising: a mine body having an axial configuration with an upper end and a lower end; A parachute assembly, the parachute assembly comprising a rubber pad disposed at the upper end of the mine body, the parachute body disposed on the rubber pad, and a pre-compressed first elastic member disposed on the lower side of the rubber pad, which is used to release elastic force to drive the rubber pad to undergo elastic deformation when the mine body is freed from the constraints of the bomb bay so as to eject the parachute body from the upper end of the mine body; The anchoring mechanism is arranged at the lower end of the mine body, and comprises at least three elastically rotatable and deployable support leg plug-ins, wherein the support leg plug-ins are folded in the bomb bay under the restraint of the bomb bay, and the support leg plug-ins are elastically rotated and deployed downward after the mine body is freed from the restraint of the bomb bay.

[0006] As a further improvement of the present invention, an umbrella cover is provided at the upper end of the mine body, and the umbrella cover is used to confine the parachute body within the mine body.

[0007] As a further improvement of the present invention, the anchoring mechanism further includes a rotating seat provided at the lower end of the mine body, a rotating shaft is provided on the rotating seat, the rotating shaft is hinged to the leg plug-in, a torsion spring is sleeved on the rotating shaft, and one end of the torsion spring is fixed to the inner wall of the rotating seat while the other end acts on the leg plug-in.

[0008] As a further improvement of the present invention, after the leg plug-ins are rotated and unfolded, they are combined into a columnar structure of an insertion rod, and a conical guiding portion is provided at the lower end of the insertion rod.

[0009] As a further improvement of the present invention, a fuse module is further provided within the mine body. The fuse module includes an electric ignition tube, a booster charge column, an expanding charge column, and a combat charge column. Among them, the booster charge column is slidably provided within the mine body. The booster charge column defines a starting point and an ending point for sliding. When the booster charge column slides to the ending point, the detonation sequence of the fuse module is aligned.

[0010] As a further improvement of the present invention, a slider is slidably provided within the mine body, the booster charge column is provided on the slider, a second elastic member is provided on one side of the slider, and the second elastic member acts on the slider to drive the booster charge column to slide from the starting point to the ending point of sliding. A locking device is provided within the mine body, and the locking device acts on the slider to restrict the slider from sliding from the starting point to the ending point.

[0011] As a further improvement of the present invention, the locking device includes a safety pin that can slide radially along the mine body. One end of the safety pin penetrates into the slider to be used for restricting the sliding of the slider. A pre-compressed third elastic member is provided within the mine body, and the third elastic member acts on the slider to drive the safety pin to slide out of the slider. An inertia safety device is provided within the mine body, and the inertia safety device is used to restrict the sliding of the safety pin.

[0012] As a further improvement of the present invention, the inertia safety device includes an inertia member that can slide axially along the mine body. The lower end of the inertia member abuts against the side wall of the safety pin and restricts the sliding of the safety pin. A fourth elastic member is provided within the mine body, and the fourth elastic member acts on the inertia member to drive the lower end of the inertia member to abut against the side wall of the safety pin.

[0013] As a further improvement of the present invention, an inertia sleeve is provided inside the mine body. The inertia member is vertically movably disposed within the inertia sleeve. A buffer groove is formed in the inertia sleeve. A clamping protrusion is provided on the side wall of the inertia member and is movably embedded in the buffer groove. The buffer groove extends upward from the bottom, and at least one direction turning portion is provided on the extending path of the buffer groove, which changes the extending direction of the buffer groove.

[0014] As a further improvement of the present invention, a clamping block is provided at the lower end of the inertia member, and a clamping groove is provided on the side wall of the safety pin shaft. When the safety pin shaft slides radially along the mine body, the clamping block can be clamped into or disengaged from the clamping groove.

[0015] Advantages of the present invention: 1. In the present invention, through the cooperation of pre-compressing the first elastic member and the rubber pad, when simulating the anti-tank mine disengaging from the ammunition compartment, the parachute canopy is quickly ejected, and is deployed by the airflow to achieve deceleration and buffering, reducing the falling speed of the mine body and enabling the mine body to land in a vertical posture, avoiding the accidental activation of the simulated anti-tank mine, and further avoiding the exposure of the deployment position information.

[0016] 2. The three groups of leg inserts are driven by torsion springs to unfold. The conical insertion rods first contact the ground, which can direct the impact force to the ground and reduce the direct force on the mine body; after the insertion rods penetrate the ground, a reaction support is formed to enhance the anti-overturning ability and prevent the displacement of the simulated anti-tank mine.

[0017] 3. When the leg inserts are retracted, the overall length is shortened, which can improve the utilization rate of the ammunition compartment space.

[0018] 4. The sliding design of the booster charge column is misaligned with the electric ignition tube during storage to prevent accidental detonation.

[0019] 5. The present invention is unlocked by the inertia member. Specifically, it is unlocked by gravity inertia after being dropped, and at the same time, it is combined with the delayed response at the turning point of the buffer groove path to prevent misjudgment of magnetic field interference in the initial stage, and has high safety performance.

Detailed implementation manners

[0022] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0023] In this specification, the orientation terms such as up, down, left, right, front, back, front side, back side, top, bottom, etc., which are mentioned or may be mentioned, are defined with respect to the structures shown in the respective drawings. The terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component. They are relative concepts and may therefore change accordingly depending on their different positions and different usage states. Therefore, these or other orientation terms should not be construed as restrictive terms.

[0024] Refer to Figures 1 to 7 , what is disclosed in the embodiment of the present invention is: An anti-tank mine simulation, which is installed in the bomb bay of an unmanned aerial vehicle and is dropped by the unmanned aerial vehicle.

[0025] The simulated anti-tank mine specifically includes: a mine body 1, which has an axial structure with an upper end and a lower end; a parachute assembly is provided at the upper end of the mine body 1. The parachute assembly includes a rubber pad 2 provided at the upper end of the mine body 1, and a parachute canopy 3 (in a folded state) is provided on the rubber pad 2. Specifically, the parachute canopy 3 has parachute cords, and the other ends of the parachute cords are connected to the upper end of the mine body 1; a pre-compressed first elastic member 4 (compression spring) is provided on the lower side of the rubber pad 2, which is used to release elastic force to drive the rubber pad 2 to undergo elastic deformation when the mine body 1 is released from the restraint of the ammunition compartment, so as to eject the parachute canopy 3 out of the upper end of the mine body 1; when the simulated anti-tank mine (mine body 1) is dropped, specifically when the mine body 1 is released from the restraint of the ammunition compartment, the pre-compressed first elastic member 4 releases elastic force, pushing the rubber pad 2 to deform upward rapidly. The rapid deformation of the rubber pad 2 ejects the folded parachute canopy 3 out of the upper end of the mine body 1. After that, the parachute canopy 3 unfolds under the action of the airflow, forming deceleration and buffering, and making the whole mine body 1 descend in a vertical posture; through the above settings, the falling speed of the mine body 1 is reduced, thereby reducing the instantaneous impact force borne by the mine body 1 when it touches the ground. In addition, since the parachute canopy 3 makes the whole mine body 1 descend in a vertical posture, it avoids the mine body 1 from touching the ground first at an inclined angle or in a vertical direction, avoiding the misactivation of the simulated anti-tank mine in this embodiment, and further avoiding the exposure of the laid position information; in addition, as Figure 2 shown, due to the upward elastic deformation of the rubber pad 2, an upward protrusion is formed at the upper end of the mine body 1, thereby preventing sand and water from accumulating at the upper end of the mine body 1 and avoiding damage to the simulated anti-tank mine due to sediment or rain.

[0026] In addition, in this embodiment, an umbrella cover 5 is provided at the upper end of the mine body 1. When the simulated anti-tank mine is stored, the umbrella cover 5 is installed at the upper end of the mine body 1 and locked by bolts to limit the parachute canopy 3 within the mine body 1; of course, when it is necessary to lay the simulated anti-tank mine, specifically when the mine body 1 is installed in the ammunition compartment, the bolts need to be removed so that the parachute canopy 3 can be separated from the mine body 1 during dropping.

[0027] Of course, even if the mine body 1 is acted upon by the parachute assembly, which reduces the falling speed and thus reduces the instantaneous impact force borne by the mine body 1, the mine body 1 is still likely to be damaged due to direct contact with the ground, thereby causing the simulated anti-tank mine to be falsely activated. Based on this, in the present embodiment, an anchoring mechanism is provided at the lower end of the mine body 1, and the anchoring mechanism includes at least three elastically rotatable and deployable support leg plug-ins 6, the support leg plug-ins 6 are retracted in the bomb bay by the constraints of the bomb bay, and the support leg plug-ins 6 are elastically rotated and deployed downward after the mine body 1 is freed from the constraints of the bomb bay; specifically, the anchoring mechanism also includes a rotating seat 7 provided at the lower end of the mine body 1, a rotating shaft is provided on the rotating seat 7, the rotating shaft is hinged to the support leg plug-in 6, a torsion spring 8 is sleeved on the rotating shaft, and one end of the torsion spring 8 is fixed to the inner wall of the rotating seat 7 and the other end acts on the support leg plug-in 6; Figure 1 , Figure 2 As shown, when the mine body 1 is located in the bomb bay, the support leg plug-in 6 is rotated and retracted to one side of the side wall of the mine body 1. At this time, the support leg plug-in 6 is acted upon by the torsion spring 8 and fits tightly to the inner wall of the bomb bay, thereby preventing the simulated anti-tank mine from detaching from the bomb bay due to misoperation during loading; when being dropped, the support leg plug-in 6 is acted upon by the torsion spring 8 and rotates with the rotation axis as a fulcrum, and finally makes the support leg plug-in 6 face vertically downward, at which time the support leg plug-in 6 can first contact the ground, that is, the support leg plug-in 6 first bears the instantaneous impact force, reducing the instantaneous impact force directly received by the mine body 1, so as to avoid damage to the mine body 1; and in this embodiment, each of the support leg plug-ins 6 is combined into a plug rod 601 with a columnar structure at the lower end after being rotated and unfolded, and a conical guide portion is provided at the lower end of the plug rod 601, and a connecting portion 602 is provided at the upper end of the plug rod 601 for connecting the rotation axis, wherein the The diameter of the connecting portion 602 gradually increases from bottom to top, so that the insertion rod 601 can still penetrate the ground after landing, and when the connecting portion 602 contacts the ground, a reaction force support is formed between the connecting portion 602 and the ground, thereby being able to transmit the instantaneous impact force to the ground, further reducing the instantaneous impact force on the mine body 1, and avoiding damage to the mine body 1 and mis-starting; in addition, in this embodiment, when the simulated anti-tank mine is laid, the insertion rod 601 penetrates the ground, which can prevent the simulated anti-tank mine from being offset by wind or ground vibration, thereby improving the anti-overturning ability; it is worth mentioning that in this embodiment, when the support leg plug-in 6 of the simulated anti-tank mine is folded and then installed in the bomb bay, it is unfolded outside the bomb bay, so that the overall length of the simulated anti-tank mine is less when it is in the bomb bay than when it is outside the bomb bay, thereby improving the space utilization rate of the bomb bay; in addition, when storing, it can also be bound by ropes 101 and then stacked for easy storage.

[0028] Of course, since the simulated anti-tank mine also needs to simulate the actual combat effect, when vehicles such as enemy tanks and armored personnel carriers pass by, an acoustic and optical alarm signal is emitted or smoke is released for marking. Based on this, in this embodiment, it further includes a fuse module disposed in the mine body 1. The fuse module includes an electric ignition tube 9, a booster charge column 10, an expanding charge column 11, and a main charge column 12. In addition, a signal receiving device 14, a power supply 13, a magnetic induction probe (not shown in the figure), and a signal processor (such as an MCU) are also disposed in the mine body 1. All of its electrical components are electrically connected, and the electric ignition tube 9 is also electrically connected to the signal processor; when vehicles such as enemy tanks and armored personnel carriers pass by, the magnetic induction probe detects the change in the surrounding magnetic field (when a metal target such as an enemy tank enters the detection range of the magnetic induction probe, its movement causes a change in the surrounding magnetic field). At this time, the magnetic induction probe converts the magnetic field change into an electrical signal and transmits the electrical signal to the signal processor. At this time, the signal processor analyzes and processes it. If the signal exceeds the set threshold, a high-voltage pulse current is sent to the electric ignition tube 9, causing the electric ignition tube 9 to ignite the booster charge column 10. The energy is amplified by the expanding charge column 11 and finally detonates the main charge column 12 (the main charge). Of course, in this embodiment, the main charge column 12 is only used for training and is not for causing actual damage. Based on this, the main charge column 12 mainly uses low-velocity explosives, and a smoke agent ignition layer is also provided in the main charge column 12. After the main charge column 12 is ignited, thick smoke is ejected from the upper end of the mine body 1. Of course, this embodiment is used to optimize the misactivation of the simulated anti-tank mine, and how the main charge column 12 generates thick smoke is a conventional technical means in the art and will not be elaborated here.

[0029] Wherein, the booster charge column 10 is slidably disposed in the mine body 1. The booster charge column 10 defines a starting point and an ending point of sliding. When the booster charge column 10 slides to the ending point, the detonation sequence of the fuse module is aligned; that is, in this embodiment, when the booster charge column 10 is stored, it is not aligned with the electric ignition tube 9 and the expanding charge column 11. At this time, even if the electric ignition tube 9 is accidentally triggered, the main charge column 12 will not be ignited, avoiding the accidental detonation of the simulated anti-tank mine.

[0030] A slider 15 is slidably disposed within the mine body 1, and the booster charge column 10 is disposed on the slider 15. A second elastic member 16 (compression spring) is disposed on one side of the slider 15. The second elastic member 16 acts on the slider 15 to drive the booster charge column 10 to slide from the starting point to the ending point. A locking device is disposed within the mine body 1. The locking device acts on the slider 15 to restrict the slider 15 from sliding from the starting point to the ending point; when the locking device no longer restricts the sliding of the slider 15, the second elastic member 16 releases elastic potential energy, causing the slider 15 to slide from the starting point to the ending point, thereby aligning the detonation train. The structure is simple and the response is rapid; in addition, in this embodiment, a brush piece 17 is disposed on the slider 15, and the circuit of the power supply 13 is connected to the brush piece 17. A circuit connection point 18 for communicating with the brush piece 17 is disposed at the ending point. When the slider 15 slides to the ending point, the brush piece 17 contacts and communicates with the circuit connection point 18, that is, the slider 15 serves as the circuit switch of the fuse module in this embodiment, thereby preventing the simulated anti-tank mine from triggering the electric detonator 9 during storage, and further avoiding the accidental detonation of the simulated anti-tank mine; and by controlling the sliding of the slider 15 through the locking device, it is possible to prevent the simulated anti-tank mine from being accidentally fired during storage, transportation or loading, effectively avoiding safety accidents caused by mechanical failures or operational errors.

[0031] In this embodiment, the locking device includes a safety pin 19 that can slide radially along the mine body 1. One end of the safety pin 19 penetrates into the slider 15 to be used for restricting the sliding of the slider 15. A pre-compressed third elastic member 27 (compression spring) is disposed within the mine body 1. The third elastic member 27 acts on the slider 15 to drive the safety pin 19 to slide out of the slider 15; that is, when it is necessary to control the simulated anti-tank mine to be normally triggered, the safety pin 19 is controlled to slide so that the safety pin 19 disengages from the slider 15. At this time, the sliding of the slider 15 is no longer restricted, and the slider 15 can slide to the ending point under the action of the second elastic member 16. The structure is simple and the operation is convenient; an inertia safety device is disposed within the mine body 1. The inertia safety device is used for restricting the sliding of the safety pin 19, that is, it is necessary to first release the inertia safety device and then control the sliding of the safety pin 19 to control the sliding of the slider 15, realize the alignment of the detonation train and the circuit connection, and implement a dual safety mechanism to prevent the simulated anti-tank mine from being accidentally activated due to misoperation, thereby ensuring the safety of personnel and equipment.

[0032] Specifically in this embodiment, the inertial safety device includes an inertial member 20 that can slide axially along the mine body 1, the lower end of the inertial member 20 abuts against the side wall of the safety pin shaft 19 and limits the sliding of the safety pin shaft 19, and a fourth elastic member 21 (compression spring) is arranged in the mine body 1, and the fourth elastic member 21 acts on the inertial member 20 to drive the lower end of the inertial member 20 to abut against the side wall of the safety pin shaft 19; in this embodiment, the inertial member 20 needs to be activated when the simulated anti-tank mine is dropped. Specifically, when the simulated anti-tank mine is dropped, The simulated anti-tank mine moves downward due to gravity, and at this time the inertial member 20 moves upward relative to the safety pin shaft 19 due to the inertia of the object, compressing the fourth elastic member 21 and disengaging from the safety pin shaft 19, and the safety pin shaft 19 is no longer restricted from sliding. The simulated anti-tank mine needs to be dropped before the safety can be released, which can effectively prevent the simulated anti-tank mine from being accidentally triggered during storage, transportation or loading, and the safety is released by inertia, so that the overall structure of the simulated anti-tank mine is simple, the demand for complex structures is reduced, and the manufacturing cost and maintenance cost are reduced.

[0033] Of course, due to the limitation by the inertial element 20, when the simulated anti-tank mine is dropped, the inertial element 20 will respond when the simulated anti-tank mine just leaves the bomb bay, thereby aligning the detonation sequence and connecting the circuit. At this time, the simulated anti-tank mine is still close to the bomb bay (unmanned aerial vehicle). If the magnetic induction probe senses the change in the magnetic field and transmits the signal to the signal processor, the signal processor may make a wrong judgment at this time, thereby causing the simulated anti-tank mine to be mistakenly started. Based on this, in this embodiment; an inertial sleeve 22 is provided in the mine body 1, and the inertial element 20 can be lifted and lowered in the inertial sleeve 22. The buffer groove 23 is provided in the inertial sleeve 22, and the side wall of the inertial element 20 is provided with a movable embedded in The latching protrusion 24 in the buffer groove 23 is arranged to extend from bottom to top, and at least one direction turning portion is arranged on the extension path of the buffer groove 23, and the direction turning portion changes the extension direction of the buffer groove 23; the inertial member 20 moves in the inertial sleeve 22, and when moving, the latching protrusion 24 needs to move along the extension path of the buffer groove 23. When the latching protrusion 24 encounters the direction turning portion, the moving direction is changed, but the overall movement is still from bottom to top, delaying the arrival time of the inertial member 20, thereby slowing down the rising speed of the inertial member 20, thereby avoiding false triggering of the simulated anti-tank mine due to close-range magnetic field interference at the initial stage of placement.

[0034] In addition, in the present embodiment, when simulating the handling and transportation of anti-tank mines, the inertial member 20 may be mistakenly started or moved due to misoperation, thereby causing mis-triggering. Based on this, in the present embodiment, a block 25 is provided at the lower end of the inertial member 20, and a slot 26 is provided on the side wall of the safety pin shaft 19. When the safety pin shaft 19 slides radially along the mine body 1, the block 25 can be inserted into or disengaged from the slot 26. Specifically, as shown in the figure, the slot 26 is located on the side of the inertial member 20 close to the slider 15, and the safety pin shaft 19 is at the third Under the action of the elastic member 27, the inertial member 20 moves outward, so that the card slot 26 cooperates with the card block 25. At this time, the inertial member 20 is restricted from moving axially along the mine body 1, and the inertial member 20 is locked. At this time, the inertial member 20 can be prevented from being started by mistake; of course, it is necessary to control the inertial member 20 to be unlocked so that the simulated anti-tank mine can be started normally. Based on this, an axial unlocking member 28 is also provided in this embodiment, and one end of the axial unlocking member 28 penetrates into the mine body 1 and abuts against the safety pin shaft 19; when loading (controlling the simulated anti-tank mine to enter the bomb compartment), the first First, the axial unlocking member 28 is controlled to move radially along the mine body 1, so that it drives the safety pin shaft 19 to move and compress the third elastic member 27. At this time, the card slot 26 is disengaged from the card block 25, and the inertia member 20 is no longer locked. Then the simulated anti-tank mine is controlled to enter the bomb bay. Of course, when the axial unlocking member 28 is in the bomb bay, the other end abuts against the side wall of the bomb bay to prevent the safety pin shaft 19 from resetting. When the mine is released, the other end of the axial unlocking member 28 is disengaged from the bomb bay constraint, and under the action of the third elastic member 27, it is driven by the safety pin shaft 19 to move in the opposite direction. It is worth mentioning that during the delivery process, when the simulated anti-tank mine is initially delivered and has not yet completely left the bomb bay, the inertial member 20 moves upward by a certain distance due to inertia, and the card slot 26 and the card block 25 can no longer be staggered with each other. At this time, even if the safety pin shaft 19 moves outward under the action of the third elastic member 27, the safety pin shaft 19 can no longer limit the upward movement of the inertial member 20; the axial unlocking member 28 locks the safety pin shaft 19 when loading and is automatically released after delivery, thereby ensuring the safe switching between the transportation and combat states.

[0035] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned implementation cases, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned implementation cases, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation cases of the present invention.

The third elastic member (27) acts on the slider (15) to drive the safety pin shaft (19) to slide out of the slider (15). An inertial safety device is arranged in the mine body (1), and the inertial safety device is used to constrain the sliding of the safety pin shaft (19).

8. A simulated anti-tank mine according to claim 7, characterized in that: The inertial safety device includes an inertial member (20) that can slide axially along the mine body (1). The lower end of the inertial member (20) abuts against the side wall of the safety pin shaft (19) and restricts the sliding of the safety pin shaft (19). A fourth elastic member (21) is arranged in the mine body (1). The fourth elastic member (21) acts on the inertial member (20) to drive the lower end of the inertial member (20) to abut against the side wall of the safety pin shaft (19).

9. A simulated anti-tank mine according to claim 8, characterized in that: An inertial sleeve (22) is arranged in the mine body (1). The inertial member (20) is arranged in the inertial sleeve (22) in a liftable manner. A buffer groove (23) is formed in the inertial sleeve (22). A clamping protrusion (24) that is movably embedded in the buffer groove (23) is arranged on the side wall of the inertial member (20). The buffer groove (23) extends from bottom to top, and at least one direction turning portion is arranged on the extending path of the buffer groove (23). The direction turning portion changes the extending direction of the buffer groove (23).

10. A simulated anti-tank mine according to claim 9, characterized in that: A clamping block (25) is arranged at the lower end of the inertial member (20). A clamping groove (26) is arranged on the side wall of the safety pin shaft (19). When the safety pin shaft (19) slides radially along the mine body (1), the clamping block (25) can be clamped into or disengaged from the clamping groove (26).
