Description

Technical Field

[0001] This application belongs to the technical field of drone interception equipment, and relates to an open-air hangar anti-drone interception and protection device. Background Technology

[0002] Currently, open-air aircraft hangars lack drone protection devices, representing a technological gap. The main challenges are how to install such devices in existing open-air hangars and how to design these devices to meet protection requirements. The protection devices should be designed for rapid restoration after use, without disrupting normal hangar operations. Summary of the Invention

[0003] In view of this, this application designs an open-type hangar anti-drone interception and protection device. The device has a reliable and simple structure, is easy to maintain and use, and allows for convenient deployment and closure of the protective netting at the hangar entrance, thereby forming a protective barrier for the equipment inside the hangar.

[0004] An open-air hangar anti-drone interception and protection device is based on the existing open-air hangar, with the addition of a protective net opening and closing device. By vertically suspending and horizontally opening and closing the protective net, the net can be easily deployed and closed at the hangar entrance, forming a protective barrier for the equipment inside the hangar.

[0005] Open-air hangar anti-drone protective netting features impact resistance, wide coverage, and light weight. It also boasts excellent flame retardancy and water resistance, ensuring the anti-drone interception and protection needs of existing open-air hangars. This prevents drones from entering the hangar to launch attacks and interfere with external personnel's direct observation of aircraft or equipment inside the hangar, making it an economical and efficient protective measure for open-air hangars.

[0006] An open-air hangar anti-drone interception and protection device comprises a double-groove guide rail 1, an opening and closing motor 2, a spring buckle 3, a side connecting plate 4, a self-locking wire rope winch 5, expansion screws 6, a protective net 7, and lifting eye screws 8.

[0007] The double-groove guide rail 1 mounting bracket is used to fix the netting on the lower surface of the machine shed beam, serving as a vertical suspension mechanism for the protective netting. Considering that the netting consists of two independent nets and requires a certain degree of overlap after opening and closing, a double-groove guide rail with trolleys is selected. The guide rail is made of aluminum alloy, formed under high temperature and pressure, to meet the requirements for netting suspension and drone impact loads. The hanging wheels use POM material with bearings for corrosion and aging resistance. Up to seven pulleys can be installed per meter of aluminum alloy guide rail for suspending the netting, ensuring that the netting does not experience localized sinking or large gaps after vertical suspension.

[0008] The opening and closing motor 2 is the power source for the mesh opening and closing device, and is installed on the transmission boxes on the left and right sides of the guide rail. It controls the opening and closing of the protective mesh 7 along the double-groove guide rail.

[0009] The spring buckles 3 are arranged on the net body and are load-bearing components connected to the guide rail pulleys, left and right column side connectors, and bottom wire rope. Each spring buckle can bear a load of not less than 250 kg. The spring buckles are arranged along the outer edge of the net body (on the left net body, they are arranged at the top, left, and bottom; on the right net body, they are arranged at the top, right, and bottom). The spring buckles are evenly distributed according to the net body's dimensions.

[0010] The side connector 4 is a part installed on the surface of the left and right columns of the machine house and used for connection and fixation of the spring buckle 3. The side connector 4 is installed on the surface of the flange plate corresponding to the web plate of the column by welding.

[0011] The self-locking wire rope winch 5 is bolted to the bottom of the left column of the machine shed. After the net is unfolded into place by the opening and closing mechanism, the movable end (hook) of the wire rope winch is pulled to the hanging ring at the bottom of the right column, and the tension of the wire rope is adjusted by hand crank. Then, the spring buckles at the bottom of the net are fastened to the wire rope to complete the bottom fixing of the net.

[0012] To ensure the steel wire rope's displacement meets requirements in the event of a drone impacting the net, expansion bolts (6) are installed on the corresponding ground surfaces to hook and secure the pulled-out steel wire rope. Round holes must be drilled at the locations where the expansion bolts are installed. Cover plates are installed over these holes when the net is not open to ensure unobstructed access for equipment within the machine shed.

[0013] The netting opens and closes horizontally. When the netting closes from both sides to the middle, there is a certain overlap in the middle. To ensure that the vertical edges of the overlapping netting are taut, auxiliary traction ropes are used to fix the netting. After the netting closes, the auxiliary traction ropes for fixing the two nettings are pulled to the eye bolts 8 on the left and right columns and tightened. The diameter of the auxiliary traction ropes should not be less than the diameter of the netting mesh.

[0014] (1) The double-groove guide rail mounting bracket is fixedly installed on the lower surface of the machine shed beam as a vertical suspension installation mechanism for the protective net body. Considering that the net body consists of two independent net bodies and requires a certain degree of overlap after opening and closing, the guide rail is selected as a double-groove guide rail and equipped with a pulley. The guide rail material is aluminum alloy, formed under high temperature and high pressure, to meet the requirements of net body suspension and UAV collision load. The hanging wheels adopt POM material with bearings, which is corrosion-resistant and anti-aging. Up to 7 pulleys can be set per meter of aluminum alloy guide rail for suspending the net body, ensuring that the net body will not sink locally and produce large gaps after vertical suspension.

[0015] (2) The opening and closing motor is the power source for the opening and closing device of the net body, and is installed on the transmission box on the left and right sides of the guide rail respectively. It controls the opening and closing of the protective net body along the double groove guide rail. The opening and closing method of the net body is horizontal split opening. When the net body closes to the middle from both sides, there is a certain overlap in the middle of the net body. In order to ensure that the vertical edge of the overlapping net body in the middle is in a taut state, an auxiliary traction rope for fixing the net body is set. After the net body closes to the middle, the auxiliary traction ropes for fixing the two net bodies are pulled to the hanging eye screws on the left and right columns respectively and tied tightly.

[0016] (3) Spring buckles are arranged on the net body and are load-bearing components connected to the guide rail pulleys, left and right column side connectors, and bottom wire ropes. Each spring buckle can bear a load of not less than 250 kg. Spring buckles are arranged on the outer edge of the net body (on the left net body, at the top, left, and bottom; on the right net body, at the top, right, and bottom). Spring buckles are evenly distributed according to the net body's dimensions. Side connectors are parts installed on the surfaces of the left and right columns of the machine shed for connecting and fixing the spring buckles. Side connector plates are installed on the surface of the corresponding flange plate of the column web using welding.

[0017] (4) The self-locking wire rope winch is fixed to the bottom of the left column of the machine shed with bolts. After the net body is unfolded into place under the drive of the opening and closing mechanism, the movable end (hook) of the wire rope winch is pulled to the hanging ring at the bottom of the right column, and the tension of the wire rope is adjusted by hand crank. At this time, the spring buckles at the bottom of the net body are fastened to the wire rope to complete the bottom fixing of the net body. At the same time, in order to ensure that the displacement of the wire rope is sufficient when the wire rope is connected to the protective net body and the drone hits the net, expansion bolts are set on the corresponding ground. The pulled wire rope is hooked and fixed by the expansion bolts. The expansion bolts need to be installed in the ground with round holes. When the net body is not opened, the cover plate is installed on the round holes to ensure that the equipment in the machine shed can enter and exit unimpeded.

[0018] The advantages of this application are:

[0019] The open-rack anti-drone interception and protection device described in this application has a reliable structure and is easy to install and maintain; the device can quickly recover after protection, providing interception and protection for subsequent open-rack anti-drone operations.
