Description

Technical Field

[0001] The present invention relates to the technical field of active defense of fighter planes and armored combat vehicles, and in particular to active defense equipment. Background Art

[0002] Missile and drone interception is an important part of modern air defense systems. They can effectively counter incoming missile and drone threats. At present, security personnel mostly use net guns to launch capture nets to intercept and capture missiles and drones.

[0003] A Chinese patent discloses a drone interception device based on a capture net array (authorization announcement number is CN210922352U). The net array launcher can launch multiple sets of capture nets to form a capture net array. The net array can effectively improve the success rate of intercepting drones compared to a single capture net. The edges of the capture net are evenly connected with heavy blocks and the capture net is a rotating ejection, so that the capture net can be opened quickly. At the same time, it is more stable in the air after ejection, thereby improving accuracy.

[0004] According to the above reference cases, the above device directly places the capture net in a launching tube fixed on the aircraft. Since the above aircraft is a fixed-wing aircraft, although the flight speed of this type of aircraft is relatively fast, the opening of the launching tube faces downward during the upward flight of the aircraft. However, the capture net is not limited in the launching tube, which increases the possibility of the capture net sliding or falling off when the opening of the launching tube faces downward, making it difficult to ensure that the capture net can be used normally. Summary of the invention

[0005] Based on this, it is necessary to provide an active defense equipment to address the problem that existing capture net launchers are difficult to effectively lock onto the capture net, which increases the difficulty of launching the capture net and the flight accuracy.

[0006] An active defense equipment includes a net-casting rocket launcher and an explosive interception net bomb, wherein the inner side of the net-casting rocket launcher is provided with evenly distributed rifling, the explosive interception net bomb is loaded inside the net-casting rocket launcher, and the surface of the net-casting rocket launcher is provided with a positioning mechanism in contact with the explosive interception net bomb.

[0007] Furthermore, the positioning mechanism includes a mounting box fixedly connected to the surface of the net-casting rocket launcher, a positioning block is slidably connected to the interior of the mounting box, one end of the positioning block passes through the mounting box and extends to the interior of the net-casting rocket launcher, an end of the positioning block facing away from the rifling contacts an end of the explosive intercepting net bullet facing the rifling, a local vertical cross-section of the positioning block arranged inside the net-casting rocket launcher is in the shape of a right triangle, and the inclined surface of the positioning block faces the rifling.

[0008] In one of the embodiments, the positioning mechanism can automatically lock the explosive interception net bomb after the explosive interception net bomb is installed in place in the net-casting rocket launcher. This can not only prevent the explosive interception net bomb from sliding inside the net-casting rocket launcher when not in use, to ensure that the net-casting rocket launcher can accurately launch the explosive interception net bomb, but also solve the problem that the existing capture net launcher is difficult to effectively lock the capture net, which increases the difficulty of launching the capture net and the flight accuracy.

[0009] Furthermore, the explosive intercepting net bomb includes blasting ropes that are evenly distributed and twisted together, and proximity fuse devices and trigger fuse devices are installed at the twisted joints of the blasting ropes, and the proximity fuse devices and trigger fuse devices are staggered.

[0010] In one of the embodiments, the missiles or UAVs on the path can be covered over a large area by launching, so as to meet the needs of multi-point destruction. At the same time, the active defense equipment can be widely used in aircraft, armored vehicles, tanks, and even for individual soldiers, thus expanding the scope of application of the active defense equipment.

[0011] Furthermore, the ends of the outermost blasting ropes are fixedly connected with arc plates, and the four arc plates together form an arc tube, and the end of the uppermost arc plate facing the rifling contacts the positioning block.

[0012] In one of the embodiments, the arc plate can not only hide the blasting rope, the proximity fuze device and the trigger fuze device inside when not in use, which can reduce the probability of the blasting rope, the proximity fuze device and the trigger fuze device being triggered, so as to improve the safety factor of the transportation of the explosive interception net bomb, but also when the explosive interception net bomb is separated from the net-casting rocket launcher, because the arc plate itself is at the outermost side and has a larger mass, the arc plate can actively pull the blasting rope under the action of the rotating centrifugal force to accelerate the deployment rate of the blasting rope, thereby ensuring that the explosive interception net bomb can effectively intercept missiles or drones after deployment.

[0013] Furthermore, a protective plate is fixedly connected to the surface of the blasting rope, the cross-section of the protective plate is T-shaped, and one end of the four arc plates is in contact with the concave portion of the protective plate.

[0014] In one of the embodiments, the protective plate can not only limit the position of the four arc plates when not in use, but also prevent the propulsion structure in the net-casting rocket launcher from colliding with the blasting rope, approaching the fuse device and triggering the fuse device, so as to reduce the probability of premature explosion of the explosive interception net bomb, thereby improving the safety factor of use.

[0015] Furthermore, the positioning mechanism also includes a reciprocating component, which includes a wireless controller, a micro servo motor and a spring. The wireless controller is fixedly connected to the surface of the installation box, the micro servo motor is fixedly connected to the inside of the installation box, the output shaft of the micro servo motor is fixedly connected to a wire wheel, the surface of the wire wheel is fixedly connected to a connecting soft belt fixedly connected to the positioning block, and the spring is arranged between the installation box and the positioning block, and the spring is always in a compressed state.

[0016] In one embodiment, the reciprocating assembly can cooperate with the staff to actively remove the lock on the explosive interceptor net bomb to ensure that the explosive interceptor net bomb can be launched normally.

[0017] Furthermore, annular grooves are provided between the installation box and the positioning block, and two ends of the spring are respectively in contact with the two annular grooves.

[0018] In one embodiment, this can limit the running trajectory of the spring and prevent the spring from twisting or rotating.

[0019] Furthermore, the maximum diameter of the positioning block arranged inside the installation box is larger than the opening of the installation box.

[0020] In one embodiment, this can prevent the positioning block from completely separating from the mounting box, thereby achieving the purpose of effectively limiting the position of the positioning block.

[0021] Furthermore, an inverted L-groove is provided on the surface of the positioning block, and the positioning mechanism also includes an indication component, which includes a pressing plate, a pressure switch and an indicator light. The pressing plate is rotatably connected to the inside of the inverted L-groove, and the rotational connection between the pressing plate and the inverted L-groove is arranged outside the corner of the inverted L-groove. The pressure switch is embedded and installed in the interior of the installation box, and the pressure switch is arranged directly above the pressing plate. The indicator light is embedded and installed on the surface of the installation box.

[0022] In one of the embodiments, this can utilize the trend of being installed in place and locked to automatically turn on the indicator light to prompt the staff that the explosive interception net bomb has been installed in place, without the need for the staff to calibrate whether the explosive interception net bomb is installed in place by other means, making the installation work easier for the staff.

[0023] Furthermore, the length of the pressure switch extending into the interior of the installation box is smaller than the inner diameter of the inverted L-groove at its smallest point.

[0024] In one embodiment, this can ensure that the pressure switch can pass through the inverted L groove normally, so as to ensure that the positioning block can move normally.

[0025] Furthermore, the distance between the end of the pressing plate facing the pressure switch and the rotational connection between the pressing plate and the inverted L-groove is a, and the distance between the end of the pressing plate facing the pressure switch and the rotational connection between the pressing plate and the inverted L-groove is b, and the length ratio of a to b is two to three.

[0026] In one embodiment, the center of gravity of the pressing piece can be limited to one side close to the corner of the inverted L-groove. When the pressing piece is separated from the pressure switch, the pressing piece can rotate and fit with the plane of the inverted L-groove by itself under the action of gravity, without the need for manual resetting by the staff.

[0027] The above active defense equipment has the following beneficial effects:

[0028] 1. The positioning mechanism can automatically lock the explosive interception net bomb after the explosive interception net bomb is installed in place in the net-casting rocket launcher. This can not only prevent the explosive interception net bomb from sliding inside the net-casting rocket launcher when not in use, but also ensure that the net-casting rocket launcher can accurately launch the explosive interception net bomb, thereby solving the problem that the existing capture net launcher is difficult to effectively lock the capture net, which increases the difficulty of capturing the net launch and the flight accuracy;

[0029] At the same time, the positioning mechanism adopts a one-way locking design, which does not require the staff to actively operate the lock during the installation of the explosive interception net bomb, thereby reducing the installation difficulty of the staff;

[0030] In addition, the positioning mechanism can use the trend of being installed and locked to automatically turn on the indicator light to remind the staff that the explosive interception net bomb has been installed in place. The staff does not need to calibrate whether the explosive interception net bomb is installed in place by other means, making the installation work easier for the staff.

[0031] 2. The active defense equipment can cover a large area of ​​missiles or drones on the path by launching, so as to meet the needs of multi-point destruction. At the same time, the active defense equipment can be widely used in aircraft, armored vehicles, tanks, and even single soldiers, which expands the scope of application of the active defense equipment.

[0047] Combine the following Figure 1 - Figure 7 An active defense device of the present invention is described.

[0048] In one embodiment, an active defense device includes a net-casting rocket launcher 100 and an explosive interception net bomb 200, wherein the inner side of the net-casting rocket launcher 100 is provided with evenly distributed rifling 110, the explosive interception net bomb 200 is loaded inside the net-casting rocket launcher 100, and a positioning mechanism 300 in contact with the explosive interception net bomb 200 is installed on the surface of the net-casting rocket launcher 100;

[0049] The explosive interception net bomb 200 installed on the surface of the aircraft needs to be equipped with a connecting rope that does not affect the launch on the surface of the arc plate 240 and the protective plate 250 in advance, and then the connecting rope is passed through the net-casting rocket launcher 100 and connected to the electric hook lock on the surface of the aircraft. When the explosive interception net bomb 200 is fired, the connecting rope can pull the explosive interception net bomb 200 at a specified distance from the tail of the aircraft, and make the explosive interception net bomb 200 unfold to form an arc structure similar to a "deceleration parachute" to meet the needs of releasing and deploying the explosive interception net bomb 200 in advance.

[0050] When the device is installed on the surface of the aircraft, the installer needs to use the explosive interception net bomb 200 that can be connected to the electric hook lock of the aircraft in advance. When the missile is launched, the airborne radar will display the direction, speed and approximate distance of the incoming missile on the radar display screen of the fighter. At this time, what is needed is to adjust the flight direction to be consistent with the direction of the incoming missile, and then calculate the approach time according to the distance and speed, release the explosive interception net bomb 200 in advance, and ensure that the explosive interception net bomb 200 is sufficient to detonate a hundred meters after the missile approaches the rear tail of the fighter. When the explosive interception net bomb 200 is unfolded and formed, the electric hook lock of the active control surface releases the explosive interception net bomb 200;

[0051] When the device is used on a single soldier or an armored vehicle, the installer can use a disconnected explosive interception net bomb 200. When the net-casting rocket launcher 100 launches the explosive interception net bomb 200 outward, the rifling 110 can cause the explosive interception net bomb 200 to produce a gyroscopic effect during the flight inside the net-casting rocket launcher 100, causing it to rotate actively. When the explosive interception net bomb 200 is separated from the net-casting rocket launcher 100, the explosive interception net bomb 200 loses its obstruction, and the arc plate 240 moves outward under the action of the rotating centrifugal force and pulls the blasting rope 210, which can cause the blasting rope 210 to actively unfold in the process of flying toward the target. When the missile or drone contacts the proximity fuse device 220 or the trigger fuse device 230 on the blasting rope 210, the proximity fuse device 220 or the trigger fuse device 230 will ignite the blasting rope 210, and the blasting rope 210 will blast the missile or drone.

[0052] like Figure 3 As shown, the explosive interception net bomb 200 includes blasting ropes 210 that are evenly distributed and twisted with each other. The twisted joints of the blasting ropes 210 are installed with proximity fuze devices 220 and trigger fuze devices 230. The proximity fuze devices 220 and the trigger fuze devices 230 are staggered. The aperture of the interception net composed of the blasting ropes 210 needs to be controlled between 300 and 500 millimeters to effectively prevent missiles from penetrating through the holes, thereby improving the effective interception rate of missiles or drones.

[0053] The ends of the outermost blasting rope 210 are fixedly connected with an arc plate 240, and the four arc plates 240 together form an arc tube. The end of the uppermost arc plate 240 facing the rifling 110 is in contact with the positioning block 320. When not in use, the arc plate 240 can not only hide the blasting rope 210, the proximity fuze device 220 and the trigger fuze device 230 on its inner side, but also reduce the probability of the blasting rope 210, the proximity fuze device 220 and the trigger fuze device 230 being triggered, so as to improve the safety factor of the transportation of the explosive interception net bomb 200. At the same time, when the explosive interception net bomb 200 is separated from the net-casting rocket launcher 100, since the arc plate 240 itself is at the outermost side and has a large mass, the arc plate 240 can actively pull the blasting rope 210 under the action of the rotating centrifugal force to accelerate the deployment rate of the blasting rope 210, thereby ensuring that the explosive interception net bomb 200 can effectively intercept missiles or drones after deployment.

[0054] A protective plate 250 is fixedly connected to the surface of the blasting rope 210. The cross-sectional shape of the protective plate 250 is T-shaped. One end of the four arc plates 240 is in contact with the recessed part of the protective plate 250. The protective plate 250 can not only limit the position of the four arc plates 240 when not in use, but also prevent the propulsion structure in the net-casting rocket launcher 100 from colliding with the blasting rope 210, approaching the fuse device 220 and triggering the fuse device 230, so as to reduce the probability of premature explosion of the explosive intercepting net bomb 200, thereby improving the safety factor of use.

[0055] like Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the positioning mechanism 300 includes a mounting box 310 fixedly connected to the surface of the net-casting rocket 100, and a positioning block 320 is slidably connected inside the mounting box 310. One end of the positioning block 320 passes through the mounting box 310 and extends to the inside of the net-casting rocket 100. The end of the positioning block 320 facing away from the rifling 110 contacts the end of the explosive intercepting net bomb 200 facing the rifling 110. The local vertical cross-section shape of the positioning block 320 arranged inside the net-casting rocket 100 is a right triangle, and the inclined surface of the positioning block 320 faces the rifling 110; the maximum diameter of the positioning block 320 arranged inside the mounting box 310 is larger than the opening of the mounting box 310.

[0056] When the installer loads the explosive interception net bomb 200 into the net-casting rocket launcher 100, the protective plate 250 can contact the inclined surface of the positioning block 320 in advance. When the explosive interception net bomb 200 subsequently penetrates into the net-casting rocket launcher 100, the protective plate 250 actively pushes the positioning block 320 back to the installation box 310 through the inclined surface of the positioning block 320, so that the explosive interception net bomb 200 can smoothly penetrate into the net-casting rocket launcher 100. When the explosive interception net bomb 200 is installed in place, At this time, the positioning block 320 is just offset from the explosive interception net bomb 200. At this time, the spring 333 quickly pushes the positioning block 320 back, so that the positioning block 320 is pressed against the outer side of the uppermost arc plate 240 in the explosive interception net bomb 200, and the explosive interception net bomb 200 is effectively confined inside the net-casting rocket launcher 100. Even if the net-casting rocket launcher 100 opens downward, this can prevent the explosive interception net bomb 200 from sliding outward, so as to achieve the effect of effectively limiting the position of the explosive interception net bomb 200.

[0057] like Figure 4 , Figure 5 and Figure 6 As shown, the positioning mechanism 300 also includes a reciprocating component 330, which includes a wireless controller 331, a micro servo motor 332 and a spring 333. The wireless controller 331 is fixedly connected to the surface of the installation box 310, the micro servo motor 332 is fixedly connected to the inside of the installation box 310, the output shaft of the micro servo motor 332 is fixedly connected to a wire wheel 334, the surface of the wire wheel 334 is fixedly connected to a connecting soft belt 335 fixedly connected to the positioning block 320, the spring 333 is arranged between the installation box 310 and the positioning block 320, and the spring 333 is always in a compressed state; an annular groove 340 is opened between the installation box 310 and the positioning block 320, and the two ends of the spring 333 are respectively in contact with the two annular grooves 340;

[0058] Before the user starts the net-casting rocket launcher 100, the user needs to send an unlocking command to the wireless controller 331 in advance. The wireless controller 331 controls the micro servo motor 332 to rotate in the corresponding direction according to the command. The micro servo motor 332 drives the wire wheel 334 to rotate. The wire wheel 334 winds the connecting soft belt 335. The connecting soft belt 335 drives the positioning block 320 to quickly move away from the explosive intercepting net bomb 200 until the positioning block 320 is completely retracted into the installation box 310.

[0059] When the user needs to limit the explosive intercepting net bomb 200 again, the user only needs to control the rotation of the micro servo motor 332 through the wireless controller 331. The micro servo motor 332 drives the wire wheel 334 to gradually release the connecting soft belt 335. During this process, the spring 333 gradually pushes back the positioning block 320, so that the positioning block 320 moves toward the inside of the net-casting rocket launcher 100 until the positioning block 320 is reset.

[0060] like Figure 5 , Figure 6 and Figure 7 As shown, an inverted L-groove 321 is provided on the surface of the positioning block 320, and the positioning mechanism 300 also includes an indicating assembly 350, which includes a pressing piece 351, a pressure switch 352 and an indicator light 353. The pressing piece 351 is rotatably connected to the inside of the inverted L-groove 321, and the rotational connection between the pressing piece 351 and the inverted L-groove 321 is arranged outside the corner of the inverted L-groove 321. The pressure switch 352 is embedded and installed in the inside of the installation box 310, and the pressure switch 352 is arranged directly above the pressing piece 351. The indicator light 353 is embedded and installed on the surface of the installation box 310; the length of the pressure switch 352 extending to the inside of the installation box 310 is less than the inner diameter of the smallest part of the inverted L-groove 321; the distance between the end of the pressing piece 351 facing the pressure switch 352 and the rotational connection between the pressing piece 351 and the inverted L-groove 321 is a, and the distance between the end of the pressing piece 351 facing the pressure switch 352 and the rotational connection between the pressing piece 351 and the inverted L-groove 321 is b, and the length ratio of a to b is two to three;

[0061] When the protective plate 250 squeezes the positioning block 320 to move upward, the positioning block 320 drives the pressing piece 351 to move upward together through the inverted L-groove 321. When the top surface of the pressing piece 351 contacts the pressure switch 352, since the bottom surface of the pressing piece 351 contacts the inverted L-groove 321, the pressure switch 352 can easily flip the pressing piece 351, so that the pressure switch 352 is not triggered. When the explosive interception net bomb 200 is installed in place, the positioning block 320 drives the pressing piece 351 to move downward synchronously through the inverted L-groove 321 during the downward movement driven by the spring 333. When the bottom surface of the pressing piece 351 contacts the pressure switch 352, since the bottom surface of the pressing piece 351 contacts the inverted L-groove 321, the pressing piece 351 cannot be flipped normally. The pressing piece 351 presses through the pressure switch 352, and the pressure switch 352 controls the opening of the indicator light 353. At this time, the installer can judge that the explosive interception net bomb 200 has been installed in place through the lit indicator light 353.

[0062] It should be noted that the net-casting rocket launcher 100, blasting rope 210, proximity fuse device 220, trigger fuse device 230, wireless controller 331, micro servo motor 332, pressure switch 352 and indicator light 353 in the above description are relatively mature devices in the existing technology. The specific models can be selected according to actual needs and will not be elaborated here.

[0063] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
