Description

Technical Field

[0001] This application relates to the field of unmanned aerial vehicle (UAV) equipment technology, and in particular to a net-collision recovery device for a fixed-wing UAV. Background Technology

[0002] With the rapid development of drone technology, small fixed-wing drones have demonstrated irreplaceable application value in complex scenarios such as mountain terrain mapping, forest fire monitoring, and disaster emergency search and rescue due to their strong endurance, wide operating range, and high payload adaptability.

[0003] Currently, net-based recovery technology has become the mainstream solution for drone recovery in runway-less conditions. This technology absorbs the kinetic energy of the drone upon landing through the synergistic action of the intercepting net and the buffer damping system, allowing it to decelerate safely within a confined space.

[0004] However, traditional net-blocking devices generally use steel truss structures as the main support. The steel truss structure is deployed to a designated location, and the interception net is installed on the steel truss structure before it can be used. The steel truss structure is composed of many metal components connected by many bolts. Although it can ensure the stability of the device, the overall weight is heavy, making it difficult to transport quickly in rugged mountainous environments. The bolt assembly process is cumbersome and the deployment efficiency is low. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a net-collision recovery device for fixed-wing UAVs, which can improve deployment efficiency.

[0006] This application provides a net-collision recovery device for a fixed-wing unmanned aerial vehicle, comprising:

[0007] A net-collision recovery device for a fixed-wing unmanned aerial vehicle (UAV), characterized in that it comprises:

[0008] Columns, movable rods, connecting rods, movable plates, netting, and tripods;

[0009] One end of the column is connected to the tripod, and a fixed plate is provided on the other end. The movable rod is movably connected to the fixed plate, and the interception net is provided on the end of the movable rod away from the fixed plate. The interception net is used to intercept drones.

[0010] The movable plate is sleeved on the column and is located between the leg and the fixed plate. The movable rod is connected to the movable plate through the connecting rod. The movable plate and the connecting rod cooperate to control the rotation of the movable rod.

[0011] Optionally, the interception net includes a first interception net and a second interception net, the first interception net and the second interception net being connected to the movable pole respectively, and the first interception net and the second interception net being parallel.

[0012] Optionally, the material of the first barrier net is one of nylon, polyester fiber, or aramid fiber.

[0013] Optionally, a sponge block is provided on the side of the fixed plate facing the interception net.

[0014] Optionally, the interception net and the movable pole are connected in a detachable manner.

[0015] Optionally, the movable rod is arranged in an arc shape.

[0016] Optionally, a guide light is provided at the end of the movable rod, and the guide light is embedded in the movable rod.

[0017] Optionally, the leg is provided with a connecting block, and the connecting block is provided with a through hole, so that the column is connected to the through hole.

[0018] Optionally, the angle between the perforation direction on the connecting block and the horizontal plane is between 15 and 90 degrees.

[0019] As can be seen from the above technical solutions, this application has the following effects:

[0020] This application connects a column to a tripod, sets a fixed plate on the column, movably connects a movable rod to the fixed plate, connects an interception net to the end of the movable rod away from the fixed plate, and fits a movable plate onto the column. The two ends of a connecting rod are connected to the movable rod and the movable plate respectively. The movable plate and connecting rod cooperate to control the rotation of the movable rod. When the movable rod rotates and the interception net opens, the interception net intercepts the drone. In deployment, only the movable plate needs to be moved to rotate the movable rod, thus opening and closing the interception net, eliminating the need for additional bolt connections and improving deployment efficiency.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] To address the problems of traditional net-collision devices, which are mostly assembled with bolts, resulting in cumbersome assembly and low deployment efficiency, this application provides a net-collision recovery device for fixed-wing UAVs to improve deployment efficiency. The specific implementation process of this application is described below.

[0036] Please see Figures 1 to 7 The net-collision recovery device for a fixed-wing unmanned aerial vehicle provided in this application includes:

[0037] The system comprises a column 01, a movable rod 02, a connecting rod 03, a movable plate 04, an interception net 05, and a tripod 06. One end of the column 01 is connected to the tripod 06, and the other end is equipped with a fixed plate 07. The movable rod 02 is movably connected to the fixed plate 07. The interception net 05 is located on the end of the movable rod 02 away from the fixed plate 07 and is used to intercept drones. The movable plate 04 is fitted onto the column 01 and is located between the tripod 06 and the fixed plate 07. The movable rod 02 and the movable plate 04 are connected by a connecting rod 03. The movable plate 04 and the connecting rod 03 cooperate to control the rotation of the movable rod 02.

[0038] Multiple movable rods 02 are movably connected to a fixed plate 07. Each movable rod 02 is connected to a movable plate 04 via a connecting rod 03. A column 01 extends from the fixed plate 07, and the movable plate 04 is fitted onto the column 01. The movable plate 04 can be moved along the column 01 under control. When the movable plate 04 moves, the movable rods 02 are driven to rotate around the fixed plate 07 under the action of the connecting rods 03. For example, if there are 6 movable rods 02, there are 6 corresponding connecting rods 03.

[0039] Specifically, when the movable plate 04 moves towards the fixed plate 07, the connecting rod 03 pushes the movable rod 02 to retract and rotate inward, causing the ends of multiple movable rods 02 (the ends away from the fixed plate 07) to converge. At this time, the interception net 05 is stored among the multiple movable rods 02, resulting in a smaller volume that is easy to transport and store. When it is necessary to intercept a drone, the movable plate 04 is moved towards the tripod 06, and the connecting rod 03 pulls the movable rods 02 outward, causing the ends of multiple movable rods 02 (the ends away from the fixed plate 07) to open. At this time, the interception net 05 is opened and parallel to the fixed plate 07, allowing for the interception of drones.

[0040] When intercepting a drone, the drone crashes into the interception net 05. Under the impact, the interception net 05 pulls the movable rods 02 in all directions, causing the ends of the movable rods 02 (the ends away from the fixed plate 07) to converge and wrap around the drone, thereby reducing the chance of the drone falling.

[0041] It should be noted that a protruding limiting ring is set on the column 01 to limit the movable plate 04. Under normal circumstances (without external force), the movable plate 04 is restricted by the limiting ring and cannot pass through the limiting ring at will. However, the movable plate 04 can pass through the limiting ring under the action of external force. Therefore, when the movable rod 02 is in the open state (the interception net 05 is in the open state), the movable plate 04 is on the first side of the limiting ring (the side closer to the footrest 06). When the UAV hits the interception net 05, under the impact, the movable rod 02 pulls the movable plate 04 through the connecting rod 03, so that the movable plate 04 passes through the limiting ring and is on the second side of the limiting ring (the side closer to the fixed plate 07).

[0042] The tripod 06 is supported on the ground and is a triangular bracket to improve stability. The column 01 is connected to the tripod 06, and the connection between the tripod 06 and the column 01 is detachable. During transportation, the tripod 06 and the column 01 can be separated to reduce the area occupied and the burden of transportation.

[0043] In this application, a column 01 is connected to a tripod 06, a fixed plate 07 is installed on the column 01, a movable rod 02 is movably connected to the fixed plate 07, an interception net 05 is connected to the end of the movable rod 02 away from the fixed plate 07, a movable plate 04 is fitted onto the column 01, and the two ends of a connecting rod 03 are respectively connected to the movable rod 02 and the movable plate 04. The movable plate 04 cooperates with the connecting rod 03 to control the rotation of the movable rod 02. When the movable rod 02 rotates and the interception net 05 opens, the interception of the UAV is achieved through the interception net 05. In terms of deployment, only the movable plate 04 needs to be moved to achieve the rotation of the movable rod 02, that is, to achieve the opening and closing of the interception net 05, without the need for an extra bolt connection process, thus improving deployment efficiency.

[0044] Please continue reading Figures 5-6 ,in Figure 5 This is a diagram showing the situation before the interception. Figure 6 This is a schematic diagram of the interception process. In an optional embodiment, the interception net 05 includes a first net 08 and a second net 09, which are connected to the movable rod 02. The first net 08 and the second net 09 are parallel to each other. In this embodiment, by setting the first net 08 and the second net 09, when intercepting a drone, the drone first impacts the first net 08, which provides initial cushioning. The first net 08 has a certain degree of elasticity. Under the impact force, the drone impacts the second net 09, which provides secondary cushioning, thereby improving the interception effect and efficiency. Furthermore, by setting the second net 09, if the first net 08 is damaged upon impact, the second net 09 can intercept the drone, improving the safety of the interception and reducing the possibility of the drone directly impacting the fixed plate 07 due to damage to the first net 08, thus protecting the drone.

[0045] In this optional embodiment, the first barrier 08 is made of one of nylon, polyester fiber, or aramid fiber. Similarly, the second barrier 09 is also made of one of nylon, polyester fiber, or aramid fiber.

[0046] In an optional embodiment, a sponge block 10 is provided on the side of the fixed plate 07 facing the interceptor net 05. In this embodiment, the sponge block 10 is provided as a triple buffer to reduce rigid contact between the drone and the fixed plate 07.

[0047] In an optional embodiment, the interceptor net 05 and the movable rod 02 are detachably connected. In this embodiment, the detachable connection allows for easy replacement of the interceptor net 05, ensuring interception effectiveness and reducing the likelihood of using a damaged interceptor net 05.

[0048] In an optional embodiment, the movable rod 02 is arc-shaped. The end of the movable rod 02 away from the fixed plate 07 bends towards the axis of the column 01. When the drone hits the interception net 05, under the impact force, the movable rod 02 rotates inward, and the ends of the movable rod 02 (the end away from the fixed plate 07) come together, confining the drone within the space enclosed by the movable rod 02.

[0049] Please continue reading Figure 4In an optional embodiment, a guide light 11 is provided at the end of the movable rod 02, and the guide light 11 is embedded in the movable rod 02. In this embodiment, the end of the movable rod 02 is the end away from the fixed plate 07, that is, the end where the interception net 05 is located. The number of guide lights 11 is the same as the number of movable rods 02, with one guide light 11 provided on each movable rod 02. When the application is unfolded (the movable plate 04 moves towards the tripod 06), the guide lights 11 are lit, which helps the UAV to quickly determine the interception position and improve the accuracy of the interception.

[0050] In an optional embodiment, the tripod 06 is provided with a connecting block 12, which has a through hole, so that the column 01 is connected to the through hole. In this embodiment, the tripod 06 is a tripod, and the connecting block 12 is fixed to the top of the tripod. The connecting block 12 has a through hole, through which the column 01 passes to achieve the connection between the column 01 and the tripod 06. The connection between the tripod 06 and the column 01 is detachable. During transportation, the tripod 06 and the column 01 can be separated to reduce the handling volume and improve portability. When needed, the column 01 can be inserted into the through hole on the tripod 06 to complete the assembly. The assembly process is simple, thereby further improving deployment efficiency.

[0051] In an optional embodiment, the angle between the perforation direction on the connecting block 12 and the horizontal plane is between 15 and 90 degrees. In this embodiment, the perforation passes through the connecting block 12, and the tilt angle of the connecting block 12 on the stand 06 is adjustable. By adjusting the tilt angle of the connecting block 12 on the stand 06, the angle of the perforation direction can be adjusted, thereby adjusting the orientation of the column 01.

[0052] It should be noted that the above description of the disclosed embodiments enables those skilled in the art to implement or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
