[0002] The retractable metal protective net for aircraft landing and take-off platforms is a safety facility designed for helicopter landing pads or specific aircraft landing and take-off areas. The main function of this protective net is to provide the necessary safety barrier when the aircraft lands and takes off. The metal protective net can be deployed or retracted as needed. When the aircraft is ready to land, the protective net will be lowered and laid flat on the edge of the apron or in a specific area. Once the aircraft takes off and moves away, the protective net will rise without affecting the normal take-off and landing path of the aircraft. When installing the metal protective net, multiple metal protective nets will be installed around the aircraft landing and take-off platform.

[0003] During use, the existing metal protective nets for aircraft take-off and landing platforms are not easy to control the raising and lowering of the protective nets, which affects the raising and lowering efficiency of the protective nets and makes it difficult to ensure the take-off and landing safety of the aircraft.

[0025] Furthermore, the motor 105 is fixedly connected to the rear side of the reducer 106 , and the output shaft of the motor 105 is fixedly connected to the input shaft of the reducer 106 .

[0026] The integrated drive mechanism 1 realizes the automatic extension and retraction of the wire mesh 2 and the mesh frame 3. This not only improves the convenience of operation and reduces the need for manual operation, but also enables rapid response in emergency situations and improves the safety of aircraft take-off and landing.

[0027] By using a combination of motor 105 and reducer 106, precise control of the unfolding and retracting speed of the wire mesh 2 can be achieved. The function of the reducer 106 is to convert the high-speed rotation of the motor 105 into the low-speed but high-torque movement required by the drive rod 102, ensuring smooth and precise movement, avoiding damage or instability of the wire mesh 2 caused by rapid movement, and enhancing the stability and durability of the overall structure.

If parts need to be replaced or repaired, these components can be easily handled separately without large-scale disassembly of the entire structure.

[0030] When the aircraft needs to land on the top of the aircraft landing platform 6, the driving mechanism 1 drives the mounting seat 5 to rotate downward, and the mounting seat 5 drives the wire mesh 2 to spread downward through the rotating frame 4 and the mesh frame 3 to protect the surrounding of the aircraft landing platform 6 and ensure the safety of the aircraft's lifting and lowering. When the aircraft takes off, the wire mesh 2 rotates and stands upright to protect the surrounding of the aircraft landing platform 6 and prevent people from falling from the top of the aircraft landing platform 6.
