Description

Technical Field

[0001] This utility model relates to the field of aviation radio navigation facilities technology, and in particular to a modular adjustable omnidirectional beacon reflector system with a diameter of 35 meters. Background Technology

[0002] In recent years, driven by both policy and market demand, China's airport construction has accelerated. Not only has the transport airport network continued to improve, but general aviation airports have also experienced explosive growth, becoming key infrastructure supporting regional economic synergy and the rise of the low-altitude economy. China's airport development has entered a new era.

[0003] The function of the DVOR (Doppler VHF Omnidirectional Beacon) reflector antenna in the airport is to provide navigation signals for aircraft. The reflector antenna spatially superimposes the electromagnetic waves of the central antenna and the sideband antennas to form a uniform radiation field, so as to ensure the phase difference accuracy between the reference phase signal and the variable phase signal.

[0004] The conventional models are 30-meter and 40-meter diameter reflector nets. However, in remote and mountainous areas, when constructing airports, the combination of complex factors such as terrain, magnetic fields, and weather causes occasional signal loss with 30-meter diameter DVOR beacon reflector nets, affecting flight safety. Replacing them with 40-meter diameter reflector nets would require altering the entire design, involving land acquisition, changes, and construction schedules, significantly increasing costs. There is an urgent need for a reflector net that can resolve the occasional signal loss with 30-meter diameter reflector nets without affecting the overall design. Utility Model Content

[0016] Compared with the prior art, the present invention has the following features and beneficial effects.

[0017] 1. This utility model has extremely high structural rigidity and stability, effectively preventing sagging. The anti-sagging top surface system forms a main grid through "horizontal beams + longitudinal beams", and adds various reinforcing components such as horizontal braces, X-shaped braces, diagonal cables, and corner diagonal braces inside, forming a high-rigidity spatial truss system, which greatly enhances the bending and torsional resistance of the top surface, fundamentally solving the problem of sagging of the reflective net bearing surface, and ensuring the long-term accuracy and stability of the 35-meter diameter reflective net surface.

[0018] 2. This utility model has circumferential truss-type horizontal supports in the bottom connecting section, standard section and top reinforcing section of the modular support, which provides strong lateral stiffness and overall stability for the entire tower structure, effectively resisting wind loads. All major components are detachable, the force flow is clear and unambiguous, the structure has high redundancy, a large safety margin and a long service life.

[0019] 3. This utility model decomposes the support system into a bottom connecting section, a standard section, and a top reinforcing section. These sections are connected by flanges, offering excellent modularity and adjustability for easy installation and adaptation. This design enables factory prefabrication, ensuring component precision; on-site assembly only requires bolting, significantly reducing high-altitude welding work, resulting in fast, convenient, and quality-controlled installation. Furthermore, by increasing or decreasing the number of standard sections, the height of the entire system can be easily adjusted within the range of 5m to 20m, perfectly adapting to the airspace requirements of different airports or special terrain needs, achieving the flexibility of "one design, multiple heights."

[0020] 4. This utility model arranges the equipment on the ground at the bottom or on the mounting platform frame at the top, based on the total height of the support frame. This design takes into account both shortening the signal transmission path and reducing signal loss, while also considering the convenience of maintenance and the economy of the structure. When the equipment is placed at the top, a mounting platform frame with guardrails is set on the upper horizontal support, providing a safe and reliable working space for the installation, commissioning, and daily maintenance of the equipment, reducing the risks and difficulties of operation and maintenance.

[0021] 5. The top diagonal brace, short vertical bar, and short diagonal bar set in the top reinforcing section of this utility model form a stable triangular support system, ensuring a reliable connection between the top and the top surface system. The "figure-eight brace" in the section also further strengthens the connection nodes between the uprights, enhancing the structural durability and safety. Attached Figure Description
