Description

Technical Field

[0001] The utility model relates to the field of low-altitude UAV interception, in particular to an impact-resistant low-altitude UAV interceptor and interception equipment. Background Art

[0002] At present, low-altitude UAVs have been widely used in both civilian and military fields. Due to their low cost and strong concealment, and having certain reconnaissance and destruction capabilities, it is necessary to prevent UAV intrusion for a long time in environments such as military and civilian airports, major event venues, examination rooms, core infrastructure, large stadiums, prisons, border areas, battlefields, etc.

[0003] In the above environment, a flexible interception net can be considered to intercept low-altitude UAVs. The interception net has lower nodes and upper pulling nodes. The lower nodes are connected to the anchoring structure, and the upper pulling nodes are connected to a floating device that provides buoyancy. When it is not necessary to intercept low-altitude UAVs, the interception net can be retracted to facilitate the storage of the interception net and keep the airspace unobstructed; when it is necessary to intercept low-altitude UAVs, the floating device is used to lift the interception net upward to quickly deploy the interception net into a vertical or nearly vertical vertical plane state and suspend it in the area where low-altitude UAVs need to be intercepted.

[0004] However, when a low-altitude UAV collides with the interception net, the position where the interception net is impacted by the low-altitude UAV is the collision point. After the low-altitude UAV is intercepted by the interception net, it will continue to move forward for a certain distance. During the process of the low-altitude UAV continuing to move forward after being intercepted, the force of the low-altitude UAV on the collision point is transmitted to each upper pulling node and lower node through the interception net. The grid between the collision point and the above-mentioned each node will also be deformed and stretched due to the tension between the collision point and each node, and the grid that is not between the connection lines of the collision point and each node will become loose, causing the overall interception net to gradually deform into a conical shape, resulting in a reduction in the projected area of the interception net in the vertical plane and affecting the interception ability of the interception net for other low-altitude UAVs. Therefore, when using an interception net to intercept low-altitude UAVs, it is difficult to deal with continuously incoming low-altitude UAVs because the interception net is easily deformed by the impact of low-altitude UAVs. Summary of the Utility Model

[0005] The utility model solves the problem that when using an interception net to intercept low-altitude UAVs, it is difficult to deal with continuously incoming low-altitude UAVs because the interception net is easily deformed by the impact of low-altitude UAVs. Therefore, an impact-resistant low-altitude UAV interceptor and interception equipment are provided. By enhancing the stability of the interception net, the deformation amplitude of the interception net when being impacted by low-altitude UAVs is reduced, so as to successfully deal with continuously incoming low-altitude UAVs.

[0006] To solve the above technical problems, the technical solution of the utility model is as follows:

[0007] An impact-resistant low-altitude UAV interceptor, characterized in that it includes an interception net that can be deployed into a vertical or approximately vertical vertical plane state with the ground. The interception net is woven by cable-like objects or composed of flexible fabrics. The interception net includes at least two upper pull nodes and at least two lower nodes. The upper pull nodes are connected with floating devices for providing buoyancy, and the lower nodes are connected with anchoring structures. The low-altitude UAV interceptor is configured as:

[0008] The number of the upper pull nodes is at least three, and the number of the lower nodes is also at least three; and / or

[0009] The low-altitude UAV interceptor further includes a protection net and / or a restraint rope that cooperate with the interception net;

[0010] The protection net is also connected between each floating device and the anchoring structure. The protection net is located on the side of the interception net facing away from the direction of the incoming low-altitude UAV and is juxtaposed and attached to the interception net. The mesh size of the protection net is larger than the mesh size of the interception net;

[0011] The restraint rope is arranged in the grid of the interception net, and the restraint rope is connected between two vertices of the diagonal of the grid.

[0012] Preferably, the low-altitude UAV interceptor further includes the floating devices for providing buoyancy to stretch the interception net upward. The buoyancy provided by the floating devices is equal to the sum of the weight of the interception net and the downward pulling forces of all the anchoring structures.

[0013] Preferably, the floating device is a balloon or an airship.

[0014] Preferably, the airship is provided with a vertical tail fin for adjusting the course angle of the airship in the wind field; and / or

[0015] The airship is provided with a horizontal tail fin for adjusting the pitch angle of the airship in the wind field.

[0016] Preferably, the low-altitude UAV interceptor further includes the anchoring structures. Each anchoring structure is correspondingly connected to a lower node of the interception net. When the interception net is in the vertical plane state, the distance between the two farthest lower nodes is less than or equal to the distance between the corresponding two anchoring structures. The anchoring structure includes a counterweight, a vehicle that can move by itself, and a fixture on the ground.

[0017] Preferably, the low-altitude UAV interceptor further includes connecting cables. The upper pull nodes are connected to the respective floating devices through the connecting cables; and / or

[0018] The lower nodes are connected to the anchoring structures through the connecting cables.

[0019] Preferably, the connecting cables are detachably connected between the floating device / anchoring structure and the interception net, and / or

[0020] The low-altitude UAV interceptor also includes a reel for adjusting the length of the connecting cable.

[0021] Preferably, the low-altitude UAV interceptor also includes a tether, so as to utilize the tether to lock the landed aerostat.

[0022] A low-altitude UAV interception equipment includes the above-mentioned low-altitude UAV interceptor, wherein the low-altitude UAV interceptor is configured with at least two, and the interception nets of multiple UAV interceptors are arranged in a surrounding, staggered, stacked or high-low staggered form to form a large-area interception net area.

[0023] Beneficial technical effects of the technical solution of the utility model:

[0024] (I) The low-altitude UAV interceptor of this embodiment includes an aerostat and an interception net. The aerostat can be used to deploy the interception net at low altitude into a vertical plane state that is perpendicular or approximately perpendicular to the ground to intercept incoming low-altitude UAVs. The operation is simple and the configuration cost is low, and it is suitable for long-term prevention of low-altitude UAVs. When a low-altitude UAV collides with the interception net, the protective net and restraint rope that cooperate with the interception net can hinder the deformation of the interception net mesh, reduce the extent of the interception net's loose deformation into a cone, and maintain the interception net's ability to intercept other low-altitude UAVs as much as possible, thereby smoothly dealing with the continuous incoming low-altitude UAVs.

[0025] The protective net and the interception net are fitted side by side. The protective net is located on the side of the interception net facing away from the direction of the incoming low-altitude drone, and the mesh size of the protective net is larger than the mesh size of the interception net. When the incoming low-altitude drone collides with the interception net, part of the interception net near the collision point will fall into the grid of the protective net. The interception net that has not fallen into the grid of the protective net is difficult to deform significantly due to being blocked by the protective net surface, making it less likely for the interception net to become loose and deformed, and maintaining the interception net's ability to intercept other low-altitude drones as much as possible.

[0026] A restraint rope is connected within the grid of the interception net. The restraint rope is connected between two diagonal vertices of the grid. When an incoming low-altitude drone collides with the interception net, the grid between the collision point and the interception net will tend to deform and elongate due to the tension. The restraint rope connected between the diagonal vertices of the grid can hinder the elongation of the grid while transmitting the tension, thereby reducing the deformation and elongation of the grid between the collision point and each node, thereby weakening the kinetic energy of the low-altitude drone while keeping the grid of the interception net as original as possible. The interception net as a whole is not easy to loosen and deform, and the interception net's ability to intercept other low-altitude drones is maintained as much as possible.

[0027] (2) The number of upward pull nodes is at least three, and the number of lower nodes is also set to at least three. By increasing the connection points between the interception net and the anchoring structure and the aerostat, the stability of the interception net can also be improved, so that the interception net is not easily deformed when impacted by low-altitude UAVs, and the ability of the interception net to intercept other low-altitude UAVs is maintained as much as possible.

[0028] (3) When the aerostat selects an airship, a vertical tail fin is also installed at the tail of the airship. The vertical tail fin can improve the yaw stability of the airship. When the airship is in a wind field, the vertical tail fin will generate a force that pushes the airship to yaw when blown by the wind, causing the airship to rotate to a headwind state, which can reduce the overall windward area of the airship, thereby reducing the offset degree of the airship when blown by the wind, improving the stability of the airship, and enabling the interception net to be suspended in the air smoothly and play the role of intercepting low-altitude UAVs stably.

[0029] Installing a horizontal tail fin at the tail of the airship can improve the pitch stability of the airship. When the airship is in a wind field, the wing surface of the horizontal tail fin will generate a force that pushes the airship to pitch when blown by the wind, causing the airship to rotate to a headwind state and keep the head of the airship facing the wind, reducing the overall windward area of the airship, thereby reducing the offset degree of the airship when blown by the wind, improving the stability of the airship, and enabling the interception net to be suspended in the air smoothly and play the role of intercepting low-altitude UAVs stably.

[0030] (4) Connect a connection cable between the lower node and the anchoring structure, and configure a winch for adjusting the length of the connection cable. When the aerostat floats up and lifts the interception net, the height position of the interception net can be changed to adapt to intercepting low-altitude UAVs at different heights.

[0031] Connect the upper pull node and the aerostat through a connection cable, leaving a certain height distance between the aerostat and the interception net, which can avoid entanglement between the aerostat and the interception net during the process of deploying and retracting the interception net.

[0032] (5) When this interceptor is not needed to intercept low-altitude UAVs, a mooring device can be used to lock the aerostat to the ground, keeping the airspace above the interceptor unobstructed. When this interceptor is needed to intercept low-altitude UAVs, unlock the mooring device, and the aerostat will automatically float up and lift the interception net to deploy it into a vertical plane perpendicular to the ground, which can quickly and conveniently deploy the interception net and play the interception function.

[0042] The following will combine the attached Figures 1 to 6 And specific embodiments to elaborate in detail the technical solutions of a kind of impact-resistant low-altitude UAV interceptor and interception equipment of the present utility model.

[0043] Embodiment 1

[0044] Such as Figures 1 to 5As shown, an impact-resistant low-altitude UAV interceptor of this embodiment includes an interception net 1 that can be deployed into a vertical plane state that is vertical or approximately vertical to the ground, an aerostat 4 for providing buoyancy to stretch the interception net 1 upward, and an anchoring structure 3 for providing downward pulling force to the interception net 1. The interception net 1 includes two upper pulling nodes 12 and two lower pulling nodes 11. The two upper pulling nodes 12 are respectively connected to one aerostat 4, and the two lower nodes 11 are respectively connected to one anchoring structure 3. When the aerostat 4 floats upward, the total buoyancy provided by the aerostat 4 is greater than the weight of the interception net 1, thereby pulling the interception net 1 upward until the interception net 1 is deployed and tightened between the aerostat 4 and the anchoring structure 3. When the interception net 1 is pulled and tightened into a vertical plane state by the aerostat 4, the total buoyancy provided by the aerostat 4 is equal to the sum of the weight of the interception net 1 and the downward pulling force of all anchoring structures 3. The deployed interception net 1 can passively intercept all low-altitude UAVs passing through the interception net 1. It has low configuration cost and is suitable for long-term prevention of low-altitude UAVs. It does not require active monitoring and identification, nor does it require positioning, interference, and shooting down of low-altitude UAVs. It has high cost-effectiveness.

[0045] When the airship 4 pulls the interception net 1 upward, if the bottom edge of the interception net 1 bends and droops, the interception net 1 cannot be fully unfolded after being lifted. Therefore, in order to fully unfold the interception net 1, the distance between the two anchoring structures 3 in this embodiment is greater than or equal to the distance between the two lower nodes 11. When the interception net 1 is lifted and unfolded, the bottom edge of the interception net 1 can be completely tightened.

[0046] The low-altitude UAV interceptor also includes a protective net 14 and a restraint rope 13 that cooperate with the interception net 1. When a low-altitude UAV collides with the interception net 1, the protective net 14 or the restraint rope 13 can be used to prevent the mesh deformation of the interception net 1, and the interception net 1 can be kept as capable as possible of intercepting other low-altitude UAVs, thereby smoothly dealing with the continuous attack of low-altitude UAVs. In actual use, the protective net 14 or the restraint rope 13 can be used alone, or they can be configured at the same time. The specific structure of the protective net 14 and the restraint rope 13 is as follows:

[0047] The protection net 14 is also connected between the airship 4 and the anchoring structure 3, and is connected to the airship 4 and the anchoring structure 3 by cables. The protection net 14 is parallel to the interception net 1 ( Figure 2 For the convenience of display, it is not attached). The protective net 14 is located on the side of the interception net 1 that is not facing the direction of the incoming low-altitude drone. The mesh size of the protective net 14 in this embodiment is larger than the mesh size of the interception net 1. When the incoming low-altitude drone collides with the interception net 1, part of the interception net 1 near the collision point will fall into the grid of the protective net 14. The interception net 1 that is not trapped in the grid of the protective net 14 is blocked by the mesh surface of the protective net 14 and is difficult to be greatly deformed, so that the interception net 1 is not prone to loose deformation, and the ability of the interception net 1 to intercept other low-altitude drones is maintained as much as possible.

[0048] The restraint ropes 13 are connected within the meshes of the interception net 1. In this embodiment, the meshes of the interception net 1 are rectangular, and two restraint ropes 13 are connected between the two diagonal vertices of the rectangular mesh, that is, two intersecting restraint ropes 13 are connected within the mesh. When a low-altitude unmanned aerial vehicle approaching collides with the interception net 1, the meshes between the collision point and the interception net 1 will tend to deform and elongate due to the tensile force. The restraint ropes 13 connected between the diagonal vertices of the meshes can impede the elongation of the meshes while transmitting the tensile force, reducing the amplitude of the deformation and elongation of the meshes between the collision point and each node. Thus, the kinetic energy of the low-altitude unmanned aerial vehicle is weakened while the meshes of the interception net 1 are kept as intact as possible, and the whole interception net 1 is not easily loosened or deformed, and the ability of the interception net 1 to intercept other low-altitude unmanned aerial vehicles is maintained as much as possible.

[0049] Specifically, restraint ropes 13 can be arranged within each mesh of the interception net 1. Taking a quadrilateral mesh as an example, two restraint ropes 13 can be connected between the four vertices of the mesh to restrict the mesh deformation from different directions. Even for circular or other polygonal meshes, restraint ropes 13 can be connected between two opposite vertices to limit the mesh deformation. The restraint ropes 13 of each mesh can be independent, that is, the restraint ropes 13 are fixed between the two diagonal vertices of the mesh in the form of tying knots, but a single rope can also be connected between adjacent multiple meshes in the form of folding and winding or tying and fixing, and the partial rope segments within the range of each mesh are respectively used as the restraint ropes 13 within the mesh.

[0050] In this embodiment, there are two upper pull nodes 12 and two lower nodes 11. The two upper pull nodes 12 are respectively arranged at both ends of the top edge of the interception net 1; the two lower nodes 11 are respectively arranged at both ends of the bottom edge of the interception net 1. When the upper pull nodes 12 and the lower nodes 11 are tightened, the entire net surface of the interception net 1 can be tightened, and the interception net 1 is unfolded into a state perpendicular to the ground. It should be understood that the number of the upper pull nodes 12 and the lower nodes 11 is not limited to two, and more can be configured. Multiple upper pull nodes 12 and lower nodes 11 pull the interception net 1 from multiple positions respectively, and can fully unfold the interception net 1.

[0051] Specifically, the anchoring structure 3 can be any one of the ground, fixtures on the ground, counterweights, and self-propelled vehicles. When the anchoring structure 3 is the ground, the position of the low-altitude UAV interceptor is fixed, and it can play the role of intercepting low-altitude UAVs alone, or cooperate with buildings and terrain to intercept low-altitude UAVs passing through building doors, windows, and near the ground. Additionally, the anchoring structure 3 can also be a fixture on the ground, as long as it is convenient to install the low-altitude UAV interceptor. When the anchoring structure 3 is a counterweight, the position of the counterweight is not fixed. Therefore, after configuring the UAV interceptor, the position and direction of the interception net 1 can be changed by moving the counterweight to adjust the interception position. Of course, a self-propelled vehicle can also be directly selected as the anchoring structure 3, and the interception position can be flexibly adjusted by controlling the movement of the vehicle, or multiple vehicles can move away from or close to each other to control the expansion and retraction of the interception net 1 and change the size of the interception area.

[0052] Optionally, the aerostat 4 is a balloon or an airship, and the buoyancy provided by the aerostat 4 is used to lift the interception net 1 upward. When an airship is selected as the aerostat 4, a vertical tail 41 and a horizontal tail 42 for adjusting the attitude of the airship in the wind field are also provided at the tail of the airship. By cooperating the vertical tail 41 and the horizontal tail 42, the attitude of the airship in the wind field is adjusted. If the head of the airship is not in the upwind state, the wind blows to the side of the airship, and the vertical tail 41 and the horizontal tail 42 will also be affected by the wind. After the vertical tail 41 is affected by the wind, a force will be generated to push the airship to perform a yaw movement; after the wing surface of the horizontal tail 42 is affected by the wind, a force will be generated to push the airship to perform a pitch movement. The vertical tail 41 and the horizontal tail cooperate with each other to push the airship to deflect to the upwind state, thereby reducing the overall upwind area of the airship, reducing the deflection degree of the airship when affected by the wind, improving the stability of the airship, and further enabling the interception net 1 suspended under the airship to be stably suspended in the air and stably play the role of intercepting low-altitude UAVs. It should be understood that only configuring the horizontal tail 42 or only configuring the vertical tail 41 can also adjust the direction of the head of the airship to make the head of the airship as upwind as possible.

[0053] Furthermore, the low-altitude UAV interceptor further includes a connecting cable 2. The upper pulling node 12 is connected to each aerostat 4 through the connecting cable 2, and the lower node 11 is connected to the anchoring structure 3 through the connecting cable 2. After setting the connecting cable 2, the interception net 1 can rise until the connecting cable 2 between the lower node 11 and the anchoring structure 3 is straightened, that is, the interception net 1 of this interceptor does not have to extend from the ground to the position where low-altitude UAVs need to be intercepted. The upper pulling node 12 is connected to the aerostat 4 through the connecting cable 2, leaving a certain height distance between the aerostat 4 and the interception net 1, which can avoid entanglement between the aerostat 4 and the interception net 1 during the process of deploying and retracting the interception net 1.

[0054] The connection cable 2 between the pull-up node 12 and the aerostat 4 and the connection cable 2 between the lower node 11 and the anchoring structure 3 can be used separately or in combination.

[0055] In this embodiment, the low-altitude UAV interceptor further includes a winder 21 for adjusting the length of the connection cable 2. By taking in or paying out a part of the connection cable 2, the overall length of the connection cable 2 can be changed, and further the height position of the interception net 1 lifted by the aerostat 4 can be adjusted, so that the height position of the interception net 1 is controllable. Specifically, a structural form of the winder 21 is a rotatable winding drum that can be controlled. The connection cable 2 is wound around the side of the winding drum, and a motor or other rotary drive is used to drive the winding drum to rotate to take in or pay out the connection cable 2. The winding drum can be installed on the anchoring structure 3 or can be installed on the connection cable 2 through a connection structure, and the winding drum rotates relative to the connection structure in a controlled rotation manner. In addition, the winder 21 can also be a structural member that can lock a part of the connection cable 2 in a binding, winding, clamping, etc. manner, as long as the overall length of the connection cable 2 that is not locked can be changed.

[0056] In another embodiment, the connection cable 2 can also be detachably connected between the interception net 1 and the aerostat 4 or between the interception net 1 and the anchoring structure 3. When it is necessary to change the overall length of the connection cable 2, the connection cable 2 with a different length can be directly disassembled and replaced.

[0057] Furthermore, a mooring device 31 is also installed on the anchoring structure 3. When the interceptor is not needed to intercept low-altitude UAVs, the mooring device 31 can be used to lock the landing aerostat 4, so that the airspace above the interceptor remains unobstructed. When the interceptor is needed to intercept low-altitude UAVs, the mooring device 31 is unlocked, and the aerostat 4 automatically floats upward and lifts the interception net 1 to unfold into a vertical plane perpendicular to the ground, exerting the interception function and facilitating the rapid unfolding of the interception net 1. It should be understood that the mooring device 31 can also be installed separately and is independent of the anchoring structure 3.

[0058] This embodiment also discloses a low-altitude UAV interception equipment, including at least two of the above-mentioned low-altitude UAV interceptors. The interception nets 1 of multiple UAV interceptors are arranged in a surrounding, staggered, stacked or high-low scattered form to form a large-area and multi-layer interception net 1 area, so as to effectively intercept low-altitude UAVs coming from various directions and different heights and protect the safety of buildings and various facilities that need to prevent UAV attacks. In actual application, the layout of the interception net 1 can be adjusted according to the use scenario to intercept low-altitude UAVs with different directions and speeds from multiple directions and multiple arrangements respectively.

[0059] Embodiment Two

[0060] Refer to Figure 6, the difference between this embodiment and the first embodiment is that the number of the upper pull-up nodes 12 and the lower pull-down nodes 11 are both three. By increasing the connection points between the interception net 1 and the anchoring structure 3 and the airship 4, the stability of the interception net 1 can also be improved. When a low-altitude drone collides with the interception net 1, first, the grid of the interception net 1 between the collision point and the adjacent node is deformed and elongated, while the grids in other areas are not easily affected by the impact, so that the interception net 1 is not easily deformed when impacted by a low-altitude drone, and the overall deformation amplitude is small, which can maintain the ability of the interception net 1 to intercept other low-altitude drones as much as possible, and can smoothly deal with the continuous attack of low-altitude drones. It is understandable that if the number of the upper pull-up nodes 12 and the lower pull-down nodes 11 is greater, when a low-altitude drone collides with the interception net 1, there will be fewer deformed and elongated grids, and the overall deformation amplitude of the interception net 1 will be smaller.

[0061] When there are three upper pull nodes 12 and three lower nodes 11, each upper pull node 12 is connected to an airship 4, each lower node 11 is connected to an anchoring structure 3, and the distance between the two farthest lower nodes 11 is less than or equal to the distance between the corresponding two anchoring structures 3, thereby ensuring that when the interception net 1 is raised, the bottom edge of the interception net 1 can be straightened to fully unfold the interception net 1.

[0062] It should be understood that the method of increasing the number of upper pull nodes 12 and lower nodes 11 in Example 2 to improve the stability of the interception net 1 can be used alone or in combination with the measure of using the protective net 14 and the restraining rope 13 in Example 1 to improve the stability of the interception net 1.

[0063] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
