Description

Technical Field

[0001] The invention belongs to the field of capture technology and relates to a pancake-shaped capture net device, in particular to a long-range capture net capture device. Background Art

[0002] At present, in the long-range net capture technology, the net bombs with the shape similar to rifle grenades or the net missiles with the shape similar to rockets are generally used. A basic feature of this type of device is that the shape is basically similar to a cylinder, the height of the cylinder is greater than the diameter of the cylinder, and the flight direction is perpendicular to the plane of the cylinder (i.e., it flies along the axis of the cylinder). Hereinafter, devices of this type are collectively referred to as cylindrical net devices.

[0003] The problems existing in the use of the cylindrical net device are as follows:

[0004] 1) After the cylindrical net device flies to the target, it will be launched in a spreading manner from the direction of the bullet. In order to ensure the spread of the net, the bullet diameter (i.e. the circular plane diameter) needs to be relatively large, generally more than 100 mm, which results in a series of problems such as small supply and slow continuous firing speed.

[0005] 2) The internal structure of the cylindrical net device is complex. In order to improve accuracy, it is often equipped with a proximity fuze, a programmable fuze or a guidance head. Since it is difficult to determine the reading and writing position of the cylindrical fuze, this leads to a high-precision cylindrical net device with a complex structure and a very expensive price, which often exceeds the price of the target object, such as a drone.

[0006] 3) The flying direction of the cylindrical net device is perpendicular to the circular plane, and the direction in which the net is opened is often perpendicular to the circular plane. This results in the position where the net is launched often being on the side of the target object. When the target object, such as a drone, has a protective frame around the blades, the capture effect of the net is greatly reduced.

[0007] For drones with protective frames, it is necessary to provide a netting device that can improve the capture efficiency. Summary of the invention

DETAILED DESCRIPTION

[0071] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0072] In the description of the present invention, the terms "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention. The terms "connected", "connected" and "set" used in the present invention should be understood in a broad sense. For example, it can be a fixed connection or a detachable connection; it can be a direct connection or an indirect connection through an intermediate component; it can be a wired electrical connection, a radio connection, or a wireless communication signal connection. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0073] See also Figure 1-14The present invention provides the following technical solutions: a remote net capture device, the height of the device is less than the outer diameter, and is in the shape of a pancake. When in use, the device is launched along the radial direction of the device, that is, the movement direction of the device is parallel to the outer diameter plane. Specifically, the launch can be achieved by hand throwing, elastic ejection, electromagnetic launch, etc. The device includes: an intermediate control module 1, an external ejection module 2 and a capture net 3. A plurality of external ejection modules 2 are located on the periphery of the intermediate control module 1, and adjacent external ejection modules 2 are detachably connected, such as a concave-convex fitting connection, that is, one side of each external ejection module 2 is provided with an inner seam groove, and the other side is an outer seam groove, so that the two external ejection modules 2 can be spliced ​​together, or the two can be connected together by using track embedded, interlocking, etc. The external shooting module 2 and the intermediate control module 1 are detachably connected, such as a concave-convex fitting connection, that is, a protrusion or a groove (notch) is set on the external shooting module 2, and a groove (notch) or a protrusion is set at a relative position of the intermediate control module 1, so that the external shooting module 2 and the intermediate control module 1 can be connected together, or the two can be connected together by means of track embedded connection, interlocking connection, etc., and the device after assembly is cylindrical or polygonal columnar as a whole. In order to ensure the fixation between the modules, materials such as wax and colloid can also be used for bonding. Before ejection, the capture net 3 is located in an annular cavity spliced ​​by multiple external shooting modules 2. One end of the capture net 3 can be connected to the intermediate control module 1 or not, and it can be set according to actual needs. The other end of the capture net 3 is connected to the external shooting module 2. The intermediate control module 1 is used to receive operation instructions from external devices such as remote controllers and sensors. According to the operation instructions, the intermediate control module 1 delays or instantly launches the external launch module 2 (such as elastic launch or gunpowder launch, which can be achieved by commonly used technical means in the field, and this embodiment does not limit it) to ensure that the capture net 3 is horizontally deployed above the front of the target object (a certain distance, such as 0.5 to 1m, or other values, which can be set according to actual needs on site). In the process of deploying the capture net 3, the external launch module 2 serves as the power to deploy the capture net 3, horizontally deploying the capture net 3 above the front of the target object, and also serves as the sinker of the capture net 3, pulling the capture net 3 downward to make it fall on the target object (such as the top). Preferably, the intermediate control module 1 receives data by optical writing or radio frequency, and delays the launch of the capture net 3 according to the data, or uses radio remote control to directly control the launch time.When an aircraft or other commonly used carrying equipment carries the device and flies to a designated position (such as 0.5 to 1 m) above and in front of the target object, the intermediate control module 1 receives and executes the operation instruction issued by the external signal writing device, and instructs the immediate or delayed outward launch of the external launch module 2 according to the operation instruction. The external launch module 2 is separated from the intermediate control module 1, and the external launch module 2 is separated from the adjacent external launch module 2. Under the action of the launching force, the external launch module 2 acts as a power source to pull outward the capture net 3 stored in the cavity until the capture net 3 is fully opened. Due to the effects of inertia and gravity, the entire capture net 3 is approximately in a horizontally opened shape and makes a forward parabolic motion. This shape of the capture net 3 ensures that it can be launched from the target. The target falls from above. Compared with the cylindrical net device, the capture net 3 of the present application after opening increases the effective capture area. For the UAV, it is no longer affected by the protective frame around its blades, thereby improving the capture efficiency. In addition, the structure of the present application is simple, and the capture cost is lower than that of the high-precision cylindrical net device. This is because the external signal writing device can be arranged above the plane of the pancake-shaped net device, which is very convenient for the alignment of the external signal writing device and the signal receiving device (referring to the signal receiver 12), and there is no need for the complex structure of the programmable fuze writing device in the cylindrical structure net bomb, thereby greatly reducing the overall cost. At the same time, the pancake shape is also conducive to a large amount of storage, which is convenient for multiple continuous launches. It should be noted that in addition to being used to capture UAVs, the present application can also be used to capture dynamic targets. When used to capture dynamic targets, leave an empty space in the center of the capture net 3, weave the inner circle of the capture net 3 in a circle, and do not connect to the control module 1, that is, the capture net 3 is only connected to the external shooting module 2. After the capture net 3 is opened by the external shooting module 2, when capturing dynamic targets, it can be covered with a large probability, increasing the capture probability.

[0074] The different emission modes lead to changes in the specific structures of the intermediate control module 1 and the external emission module 2, as follows:

[0075] Embodiment 1

[0076] The intermediate control module 1 launches the external firing module 2 through gunpowder. Figure 2As shown, the intermediate control module 1 includes: a control circuit module 11, a signal receiver 12 (not shown in the figure), a power supply (not shown in the figure), a top plate 13 and a first shell 14. When the intermediate control module 1 is connected with the external emission module 2 by concave-convex matching, a groove or a protrusion is provided on the outer wall of the first shell 14; when the intermediate control module 1 is connected with the external emission module 2 by track embedding, a track or a slider is provided on the outer wall of the first shell 14; when the intermediate control module 1 is connected with the external emission module 2 by interlocking, a positioning member or a fastener is provided on the outer wall of the first shell 14; these structures provided on the first shell 14 are used to connect the external emission module 2 (referring to the second shell 21). A connecting fixing tube 141 is provided on the side wall (inner side) of the first shell 14. When assembling, the top plate 13 is covered on the top of the first shell 14. The power supply (such as a battery, or a capacitor) is used to power the control circuit module 11 and the signal receiver 12. The control circuit module 11 is located in the first shell 14, and the circumference of the control circuit module 11 has a plurality of electronic fuses 111. The signal receiver 12 is located in the first housing 14 and is electrically connected to the control circuit module 11. The signal receiver 12 is used to receive an operation instruction from an external signal writing device, and the operation instruction is used to instruct the control circuit module 11 to ignite the primer located in the connecting and fixing tube 141 through the electronic fuse 111. Preferably, the external signal writing device (not shown in the figure) is arranged on the top plate 13, so that the alignment of the external signal writing device and the signal receiver 12 is convenient.

[0077] The external firing module 2 includes: a second shell 21 and a propellant tube 22. When the intermediate control module 1 is connected with the external firing module 2 by means of a concave-convex fit, a protrusion or a groove is provided on the side of the second shell 21 close to the first shell 14; when the intermediate control module 1 is connected with the external firing module 2 by means of a track embedding, a slider or a track is provided on the outer wall of the first shell 14; when the intermediate control module 1 is connected with the external firing module 2 by means of an interlocking connection, a fastener or a positioning member is provided on the outer wall of the first shell 14; these structures are provided on the second shell 21 for connecting the first shell 14. The propellant tube 22 is located in the second shell 21, and is filled with gunpowder. At the same time, the propellant tube 22 is connected with the connecting and fixing tube 141, so that when the primer in the connecting and fixing tube 141 is ignited, the gunpowder in the propellant tube 22 is ignited, and the high-temperature and high-pressure gas generated by the combustion of the gunpowder continuously expands to push the external firing module 2 to be fired outward.

[0078] Embodiment 2

[0079] The middle control module 1 launches the outer shooting module 2 through elastic force. Figure 4As shown, the intermediate control module 1 includes: a power supply (not shown in the figure), a control circuit module 11 (not shown in the figure), a signal receiver 12 (not shown in the figure), a mechanical ejection mechanism 15, a spring 16, a starting device, a lock 18, a top plate 13 and a first shell 14. A spring holder 142 is provided on the side wall (inner side) of the first shell 14. One end of the spring 16 is fixedly connected to the spring holder 142. During assembly, the top plate 13 is covered on the top of the first shell 14. The lock 18 is rotatably located on the first shell 14. Preferably, a pair of lock bases 5 are provided on the first shell 14, and the lock 18 is installed on the lock base 5 through the second connecting shafts 181 on both sides, so that under the action of external force, the lock 18 can rotate along the second connecting shaft 181. The power supply (such as a battery, or a capacitor) is used to power the control circuit module 11, the signal receiver 12 and the starting device. The control circuit module 11 is located in the first shell 14, and the control circuit module 11 is connected to the starting device. The mechanical ejection mechanism 15 is located in the first housing 14, and the mechanical ejection mechanism 15 abuts against one end of the lock buckle 18. The signal receiver 12 is located in the first housing 14, and the signal receiver 12 is electrically connected to the control circuit module 11, and is used to receive an operation instruction, and the operation instruction is used to instruct the control circuit module 11 to energize the starter device to separate the mechanical ejection mechanism from the lock buckle 18. Preferably, an external signal writing device (not shown in the figure) is provided on the top plate 13, so that the external signal writing device and the signal receiver 12 are easily aligned.

[0080] The external injection module 2 includes: a second shell 21 and a connecting hinge 23. When the intermediate control module 1 and the external injection module 2 are connected by concave-convex matching, track embedding and interlocking, corresponding structures can be set on the first shell 14 and the second shell 21 respectively, and this embodiment will not be repeated. A spring storage tube 24 is set in the second shell 21. Figure 7 As shown, before ejection, the spring receiving tube 24 is connected to the spring holder 142. For example, the spring receiving tube 24 is squeezed and placed on the spring holder 142 by external force, and the spring 16 is received in the spring receiving tube 24 and is in a compressed state. The connecting hinge 23 is located in the second shell 21. The connecting hinge 23 can be hard or soft (such as a rope). One end of the connecting hinge 23 can be integrated with the second shell 21, or it can be connected to the second shell 21 in other ways, which is not limited in this embodiment. The other end of the connecting hinge 23 is provided with an inner buckle 231 (which can be understood as a groove or a rope loop). After the other end of the connecting hinge 23 is inserted into the mounting hole 7 on the side wall of the first shell 14, it is movably connected to the other end of the lock buckle 18 (referring to the end away from the mechanical ejection mechanism 15) through the inner buckle 231. During assembly, buckle the other end of the lock buckle 18 into the inner buckle 231 on the connecting hinge 23. Refer to Figure 8As shown, during ejection, the mechanical ejection mechanism 15 is attracted by the upper electromagnet switch 17 and moves upward, the mechanical ejection mechanism 15 is separated from the lock 18, the abutment force applied by the mechanical ejection mechanism 15 disappears, and the lock 18 rotates to the right (i.e., clockwise), thereby separating the lock 18 from the inner buckle 231 on the connecting hinge 23. Without restraint, the spring 16 continuously extends and pushes the connecting hinge 23 outward, thereby launching the second shell 21. It should be noted that before the electromagnet switch 17 is powered on, the safety switch 4 needs to be turned on first (i.e., the safety switch 4 is disconnected from the mechanical ejection mechanism 15) before the mechanical ejection mechanism 15 can be used. In addition, the electromagnet switch 17 is usually disconnected from the power supply.

[0081] In the above two embodiments, the similarities are that the shapes of the first shell 14, the second shell 21 and the top plate 13 are the same. For example, in the two embodiments, the first shell 14 can be a cylinder or a polygonal cylinder. The shape of the top plate 13 matches the shape of the cavity of the first shell 14. The shape of the second shell 21 matches the shape of the first shell 14. The second shell 21 is in the shape of a fan-shaped column (or a fan-like body), an isosceles trapezoidal column, etc. The number of second shells 21 is determined according to the shape of the first shell 14, and is usually not less than 3. In addition, the connection relationship between the first shell 14 and the second shell 21 and the connection relationship between adjacent second shells 21 are the same. It should be noted that the connection between the external firing module 2 and the intermediate control module 1 is mainly achieved by the mutual cooperation between the propellant tube 22 in the external firing module 2 and the connection fixing tube 141 in the intermediate control module 1, and the spring receiving tube 24 in the external firing module 2 and the spring fixer 142 in the intermediate control module 1, in addition to the cooperation between the structures (such as grooves and protrusions) on the first shell 14 and the second shell 21.

[0082] The difference between the above two embodiments is that in the first embodiment, the intermediate control module 1 launches the outer-shooting module 2 by igniting gunpowder, while in the second embodiment, the intermediate control module 1 launches the outer-shooting module 2 by elastic launching (this method can be called: elastic launching).

[0083] As an example of the specific structure of the starting device in the second embodiment, in this embodiment, the starting device is an electromagnet switch 17, and the electromagnet switch 17 is located above the mechanical ejection mechanism (referring to the control hinge 151). For example, the electromagnet switch 17 is installed at the bottom of the top plate 13 (refer to Figure 6When in use, the signal receiver 12 receives an operation instruction, which is used to instruct the control circuit module 11 to start the electromagnet switch 17. The electromagnet in the electromagnet switch 17 generates a magnetic force to attract the mechanical ejection mechanism made of metal material (such as iron) to move upward, so that the mechanical ejection mechanism is separated from the lock 18, or the starting device is a push-pull motor, that is, the push-pull motor replaces the electromagnet switch 17, and the other structures for realizing the launching function are the same. The push-pull motor (not shown in the figure) is installed at the bottom of the first shell 14, and the push-pull motor is connected to the bottom of the mechanical ejection mechanism. When in use, the signal receiver 12 receives an operation instruction, which is used to instruct the control circuit module 11 to start the push-pull motor. The output end of the push-pull motor pushes the mechanical ejection mechanism 15 upward, and the mechanical ejection mechanism 15 is separated from the lock buckle 18. After the two are separated, the abutment force applied by the mechanical ejection mechanism 15 on the lock buckle 18 disappears, and the lock buckle 18 rotates to the right (i.e., clockwise), thereby separating from the inner buckle 231 on the connecting hinge 23. Without restraint, the spring 16 resets and continuously extends to push the connecting hinge 23 outward, thereby launching the second shell 21.

[0084] As an embodiment of the specific structure of the above-mentioned mechanical ejection mechanism 15, in this embodiment, the mechanical ejection mechanism 15 includes: a control hinge 151, a support rod 152 and a fixed rod 153. A plurality of first connecting shafts 154 are arranged in the circumference (on the side wall) of the control hinge 151. It should be noted that when the starting device is an electromagnet switch 17, the control hinge 151 is made of metal material (such as iron). One end of the support rod 152 is rotatably connected (hinged) to the first connecting shaft 154, such as a groove is provided at one end of the support rod 152, and the two ends of the first connecting shaft 154 are located in through holes provided on both sides of the groove. Under the premise that one end of the connecting hinge 23 is connected to the other end of the lock buckle 18 through the inner buckle 231, the other end of the support rod 152 abuts against the lock buckle 18, which can prevent the lock buckle 18 from rotating before ejection. One end of the fixing rod 153 is connected to the bottom of the control hinge 151. When the starting device is the electromagnet switch 17, the other end of the fixing rod 153 is plug-in connected to the first housing 14. Specifically, Fig. 9As shown, a T-slot 143 is provided at the bottom of the first shell 14, and the safety switch 4 is installed in the T-slot 143. At the same time, an annular recess 1531 is provided on the side wall at the other end of the fixing rod 153, and the safety switch 4 is stuck in the annular recess 1531 of the fixing rod 153, or the fixing rod 153 is fixed to the first shell 14 using a locking member such as a latch. Both the safety switch 4 and the locking member can prevent the mechanical ejection mechanism 15 from ejecting in advance during transportation. After the device is transported to the destination, the safety switch 4 is moved out of the annular recess 1531 or the locking member such as a latch is pulled out from the first shell 14 to release the safety function. That is to say, before the electromagnet switch 17 is activated, the safety switch 4 needs to be turned on first (that is, the safety switch 4 is disconnected from the mechanical ejection mechanism 15) before the mechanical ejection mechanism 15 can be used. Preferably, refer to Figure 5 As shown, a control hinge base 6 is provided on the inner side of the bottom of the first housing 14, and the other end of the fixing rod 153 is inserted into the central through hole of the control hinge base 6 and connected to the safety switch 4 below. When the starting device is a push-pull motor type, the other end of the fixing rod 153 is connected to the push-pull motor (the connection relationship between other components is the same as above, and will not be repeated here. In addition, the manufacturing material of the control hinge 151 is not limited to metal materials). At this time, there is no need to install the safety switch 14 on the first housing 14. During transportation, as long as the push-pull motor is not started, the mechanical ejection mechanism 15 will not eject in advance.

[0085] This application designs a curtain-type capture net for the situation of adding a frame to the drone. As a supplementary option, refer to Fig.13 and Fig.14 As shown, the capture net 3 is woven from a plurality of main lines 31 and a plurality of branch lines 32. One or more main lines 31 may be formed between the intermediate control module 1 and the external projection module 2. Specifically, one end of each main line 31 is connected to the external projection module 2 (referring to the second shell 21), and the other end of each main line 31 is connected to the intermediate control module 1 (referring to the first shell 14) or not connected (such as a dynamic target). The branch line 32 is used to connect adjacent main lines 31. Pendant chains 33 are provided on the main line 31 and / or the branch line 32, and the number of the pendant chains 33 can be flexibly set according to actual needs. After locking the target object, the capture net 3 is opened to form a vertical curtain to capture the target object (such as a drone). That is, the multiple pendant chains 33 on the main line 31 and / or the branch line 32 droop during the process of the capture net 3 falling from top to bottom, passing through the frame of the drone, creating more opportunities for entanglement with its propeller blades, thereby improving the capture efficiency. In addition, the design of the capture net 3 prevents the pendant chains 33 from being entangled in advance due to the vertical pendulum effect when they are not fully opened.

[0086] As an embodiment of the specific structure of the above-mentioned pendant chain 33, in this embodiment, the pendant chain 33 includes: a vertical line 331 and a pendant 332. One end of the vertical line 331 is connected to the main line 31 and / or the branch line 32, the pendant 332 is strung on the vertical line 331, and the other end of the vertical line 331 is provided with a knot 333. Due to the existence of the knot 333, the pendant 332 will never leave the vertical line 331, or the other end of the vertical line 331 is connected to the pendant 332 by tying or other technical means commonly used in the field. It should be noted that these two ways of preventing the pendant 332 from leaving the vertical line 331 make the inner cavity shape of the pendant 332 different. Fig.11 As shown, before the external shooting module 2 is separated from the intermediate control module 1, part or all of the vertical line 331 and part of the main line 31 are stored in the inner cavity of the sinker 332, and / or part or all of the vertical line 331 and the branch line 32 are stored in the inner cavity of the sinker 332. In this way, before the capture net 3 is opened, the sinker 332 is arranged at the joint of the main line 31 and the vertical line 331 and / or the sinker 332 is arranged at the joint of the branch line 32 and the vertical line 331. Through the internal structure of the sinker 332, the friction force is used to ensure that the sinker 332 does not immediately fall along the vertical line 331 during the opening process of the capture net 3, but when the capture net 3 is opened to the limit, as shown in FIG. Fig.12 As shown, at this time, the main line 31 and / or the branch line 32 are completely straightened, and the sinker 332 is ejected from the original position at the moment when the upper part of the inner cavity is hollowed out, falls under the action of gravity, and straightens the vertical line 331. Multiple vertical lines 331 fall with the sinker 332, forming a curtain shape (such as Fig.10 As shown in the figure, which is only a simple schematic diagram), the pendant chain has more chances to be caught by the target object, such as the propeller blades of the drone, thereby reducing the effect of adding a frame to the drone and improving the capture efficiency. It should be noted that Fig.11 and Fig.12 It only illustrates the state of the pendant chain 3 on the main line 31 before and after it is opened, and the state of the pendant chain 3 on the branch line 32 before and after it is opened can also be referred to. Fig.11 and Fig.12 .
