Description

Technical Field

[0001] This utility model belongs to the technical field of airport safety protection equipment, specifically, it relates to a liftable drone protection barrier structure around airport runways. Background Technology

[0002] With the rapid development of drone technology, drones have been widely used in various fields, but they have also brought some safety hazards. The illegal intrusion of drones around airport runways may pose a serious threat to the take-off and landing of aircraft, and may even cause major safety accidents.

[0003] Currently, the most common drone protection methods around airport runways rely on fixed protective barriers. These barriers are mostly composed of metal frames and protective netting, and their protective height is fixed during the installation and construction phase, making it impossible to dynamically adjust according to actual needs. However, the requirements for protective height are relatively low during the take-off and landing of small general aviation aircraft and runway ground maintenance operations. Fixed protective barriers are difficult to adapt to these multi-scenario and multi-height protection needs. If the protective height is set too low, it cannot effectively prevent mid- to high-altitude drones from entering; if it is set too high, it will not only significantly increase material costs and the difficulty of later maintenance, but may also interfere with the normal operation of the airport in specific operational scenarios (such as low-altitude emergency rescue and temporary general aviation operations), resulting in a serious lack of flexibility and practicality in protection. At the same time, because the protective netting itself has a certain weight, and the airport outdoor environment is often affected by external forces such as strong winds and ground vibrations, the protective netting is prone to tilting on both sides and sagging in the middle after being raised and lowered, thus forming irregular protective gaps between the protective netting and the supporting frame. This could become a hidden danger channel for drones to illegally enter the runway airspace, resulting in the protective barrier failing to form a continuous and complete protective range.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a retractable drone protection barrier structure around airport runways.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A retractable drone protective barrier structure around an airport runway includes a horizontal steel beam and a second protective net. Vertical steel beams are fixedly connected to both ends of the horizontal steel beams, and a steel plate is fixedly connected to the bottom of each vertical steel beam. A first protective net is fixedly connected to the vertical steel beams. A drive assembly is installed on the horizontal steel beams. The second protective net is located directly above the horizontal steel beams, and the first protective net is located in front of the second protective net. A hanging ring is fixedly connected to the second protective net, and a steel ring is attached to the hanging ring. A counterweight is slidably connected inside the vertical steel beams. A traction rope is fixedly connected between the counterweight and the steel ring. A bolt is threaded onto the counterweight, and the nut of the bolt is tightly fitted against the vertical steel beam.

[0007] Preferably, the drive assembly includes a motor fixed on a horizontal steel bar, a threaded rod fixedly connected to the output end of the motor, a sleeve block threadedly connected to the outer wall of the threaded rod, and a connecting frame fixedly connected to the sleeve block for adjusting the height of the second protective net.

[0008] Preferably, a lifting plate is fixedly connected to the connecting frame, the lifting plate is located directly above the horizontal steel, and the second protective net is fixedly connected to the lifting plate, which facilitates the installation and use of the second protective net.

[0009] Preferably, a side plate is fixedly connected to the vertical steel, the side plate is fixedly connected to the horizontal steel, and the side plate is slidably connected to the lifting plate, thereby increasing the stability of the second protective net's vertical movement and adjustment.

[0010] Preferably, a stabilizing plate is fixedly connected to the top of the vertical steel, and the top end of the threaded rod is rotatably connected to the stabilizing plate, thereby increasing the stability of the rotation of the top end of the threaded rod.

[0011] Preferably, the vertical steel has a circular hole, and the outer circumference of the bolt at the end away from the nut is smaller than the inner circumference of the circular hole, so that the bolt can pass through the vertical steel.

[0012] Preferably, a mounting frame is fixedly connected to the vertical steel, and a guide wheel is rotatably connected to the mounting frame. The guide wheel is in contact with the traction rope to increase the stability of the traction rope's movement.

[0013] In summary, the technical effects and advantages of this utility model are as follows: This retractable drone protective barrier structure around the airport runway, through the combined use of horizontal steel, vertical steel, steel plates, and a first protective net, constitutes the basic protective facility. The height of the second protective net can be adjusted through the action of the drive components, allowing for rapid adjustment of the protective height according to the drone intrusion height and airport operational requirements, thereby enhancing the dynamic protection capability against drones around the airport runway. The combined use of hanging rings, steel rings, traction ropes, counterweights, and bolts creates a stable pulling and balancing effect on both sides of the second protective net, preventing gaps caused by tilting and ensuring that the second protective net always maintains a complete protective range, preventing drones from entering the airport runway airspace through tilted gaps.

[0014] The motor drives the threaded rod to rotate, which in turn moves the connecting frame. The lifting plate adjusts the height of the second protective net. The use of the side plate and the stabilizing plate further enhances the stability of the lifting plate adjustment, making it easier to adjust the height of the second protective net.

[0017] This utility model provides a retractable drone protective barrier structure around airport runways. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes the utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0018] Reference Figure 1-3A retractable drone protective barrier structure around an airport runway includes a horizontal steel beam 1 and a second protective net 6. Vertical steel beams 2 are fixedly connected to both ends of the horizontal steel beam 1. Two vertical steel beams 2 are provided, symmetrically distributed around the central axis of the horizontal steel beam 1. A steel plate 3 is fixedly connected to the bottom of each vertical steel beam 2. A first protective net 4 is fixedly connected to each vertical steel beam 2. A drive assembly 5 is provided on the horizontal steel beam 1 for adjusting the height of the second protective net 6. The second protective net 6 is located directly above the horizontal steel beam 1, and the first protective net 4 is located in front of the second protective net 6. Two hanging rings 7 are fixedly connected to the second protective net 6, symmetrically distributed around the central axis of the second protective net 6. A steel ring 8 is connected to the vertical steel 2, and a counterweight 10 is slidably connected inside the vertical steel 2. A traction rope 9 is fixedly connected between the counterweight 10 and the steel ring 8. A bolt 11 is threaded onto the counterweight 10. The number of hanging rings 7, steel rings 8, traction ropes 9, counterweights 10 and bolts 11 are equal and correspond one-to-one. The nuts of the bolts 11 are tightly attached to the vertical steel 2. The horizontal steel 1, vertical steel 2 and the first protective net 4 constitute the basic protective layer. The height of the second protective net 6 is adjusted by the drive component 5. During the adjustment of the second protective net 6, the hanging rings 7, steel rings 8, traction ropes 9, counterweights 10 and bolts 11 work together to form a stable pulling and balancing effect on both sides of the second protective net 6, avoiding protective gaps caused by tilting.

[0019] Reference Figure 3 The drive assembly 5 includes a motor 51 fixed on the horizontal steel 1. The motor 51 is located in the middle area of ​​the horizontal steel 1. A threaded rod 52 is fixedly connected to the output end of the motor 51. A sleeve block 53 is threadedly connected to the outer wall of the threaded rod 52. The threaded rod 52 and the sleeve block 53 are adapted to each other. A connecting frame 54 is fixedly connected to the sleeve block 53. After the motor 51 runs, the threaded rod 52 rotates, and the sleeve block 53 drives the connecting frame 54 to move up and down for adjustment.

[0020] Reference Figure 3 A lifting plate 55 is fixedly connected to the connecting frame 54. The lifting plate 55 is located directly above the horizontal steel 1. The second protective net 6 is fixedly connected to the lifting plate 55. When the connecting frame 54 moves up and down, it drives the lifting plate 55 to move, so that the protection height can be quickly adjusted according to the drone intrusion height and airport operation requirements.

[0021] Reference Figure 2-3 A side plate 56 is fixedly connected to the vertical steel 2. There are two side plates 56, which are symmetrically distributed around the central axis of the horizontal steel 1. The side plates 56 are fixedly connected to the horizontal steel 1 and slidably connected to the lifting plate 55. The side plates 56 enable the lifting plate 55 to rise or fall stably.

[0022] Reference Figure 2-3A stabilizing plate 57 is fixedly connected to the top of the vertical steel 2, and the top of the threaded rod 52 is rotatably connected to the stabilizing plate 57. The stabilizing plate 57 increases the stability of the rotation of the top of the threaded rod 52.

[0023] Reference Figure 1-2 The vertical steel 2 has a circular hole 12. Each vertical steel 2 has multiple circular holes 12 arranged in a linear array. The outer circumference of the bolt 11 at the end away from the nut is smaller than the inner circumference of the circular hole 12. After the counterweight 10 is adjusted to a suitable height, the bolt 11 passes through the circular hole 12 through the vertical steel 2 and connects with the counterweight 10, thereby fixing the position of the counterweight 10.

[0024] Reference Figure 1 and Figure 4 A mounting frame 13 is fixedly connected to the vertical steel 2, and a guide wheel 14 is rotatably connected to the mounting frame 13. The number of vertical steel 2, mounting frame 13 and guide wheel 14 are equal and correspond one-to-one. The guide wheel 14 is in contact with the traction rope 9. The mounting frame 13 and guide wheel 14 guide the traction rope 9, so that the traction rope 9 moves stably.

[0025] Working principle: Horizontal steel 1 and vertical steel 2 form an overall frame. The first protective net 4 is fixed to the vertical steel 2, forming a basic protective layer. The motor 51 is started, and its output end drives the threaded rod 52 to rotate. Because the sleeve block 53 is threadedly connected to the threaded rod 52, the sleeve block 53 moves axially along the threaded rod 52, driving the lifting plate 55 to slide up and down through the connecting frame 54. The second protective net 6 rises and falls synchronously with the lifting plate 55, thus flexibly adjusting the protective height. Simultaneously, the side plate 56 slides with the lifting plate 55, and the stabilizing plate 57 supports the rotation of the top of the threaded rod 52. To ensure stability during the lifting process, the counterweight 10 is connected to the hanging ring 7 and steel ring 8 of the second protective net 6 via the traction rope 9. The position of the counterweight 10 within the vertical steel 2 can be adjusted by loosening the bolt 11 and then tightening the bolt 11 to fix it, thereby balancing the weight of the second protective net 6. The guide wheel 14 is fixed to the traction rope 9 via the mounting bracket 13 to ensure the smoothness and stability of the traction rope 9 when it moves. This increases the stability of both sides of the second protective net 6 when it rises to its highest point, preventing the second protective net 6 from tilting after being impacted by external forces.
