Description

Technical Field

[0001] This utility model relates to the field of radome technology, and in particular to a corrosion-resistant fiberglass radome. Background Technology

[0002] An radome, also known as an electromagnetic window, is a protective cover installed on the outside of an antenna. Its main purpose is to prevent the harsh environment from affecting and interfering with the normal operation of the radar antenna without affecting the antenna's transmission or reception of electromagnetic waves, thus ensuring that the antenna operates normally under various conditions around the clock.

[0003] There is an existing radome structure with a buffer structure, such as the Chinese utility model patent with application number "CN202222235210.1" and patent name "An Impact-Resistant Fiberglass Radome". It includes: a radome body and a mounting plate. The radome body and the mounting plate are connected by a buffer assembly. The buffer assembly includes a buffer rod, a buffer ring, and a buffer tube. One end of the buffer rod is fixedly connected to the inside of the radome body, and the other end is screwed with a mounting ring. The mounting ring is provided with a buffer unit. The buffer ring and the buffer tube are both located on the top of the mounting plate, with the buffer tube located inside the buffer ring and the buffer unit located inside the buffer tube.

[0004] The design of this type of radome with a buffer structure has drawbacks. The buffer components are all made of metal, which are easily corroded and damaged during long-term outdoor use, leading to the failure of its buffering and connection functions. The protective effect of the radome will be greatly reduced, so it is necessary to improve it. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a corrosion-resistant fiberglass radome, optimize the radome structure, improve its sealing and weather resistance, and extend its service life.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a corrosion-resistant fiberglass radome, comprising a radome body, a connecting seat, and a base, wherein the bottom of the radome body and the connecting seat are sealed together by adhesive; the connecting seat is arranged in a ring shape, with a connecting ring formed on the outer edge of the bottom of the connecting seat, an internal thread on the inner wall of the connecting ring, and a buckle formed on the bottom of the connecting ring; a convex ring is formed on the upper edge of the base, with an external thread on the outer wall of the convex ring, and a buckle formed below the external thread; the base is connected to the external thread of the convex ring through the internal thread of the connecting ring thread, and the buckle is snapped together with the buckle.

[0007] In a further technical solution, a limiting ring is formed on the upper inner edge of the connecting seat, the bottom opening of the cover is fitted onto the limiting ring, and the outer wall of the limiting ring is formed with an arc-shaped guide surface.

[0008] In a further technical solution, the connecting seat has a recessed groove formed on the outside of the limiting ring. The groove is filled with silicone building sealant. The cover is embedded in the groove and glued to the connecting seat.

[0009] In a further technical solution, an assembly opening is provided at the center of the base, and the upper part of the assembly opening is formed with a chamfer for wedge positioning.

[0010] In a further technical solution, the top surface of the base is provided with multiple connecting pipes.

[0011] In a further technical solution, the side of the base is formed with a connecting part, and the connecting part has a through hole for bolt fixing assembly.

[0012] In a further technical solution, the cover is formed from the outside to the inside and includes a cover layer, an aging-resistant layer, a fiberglass layer, an anti-ultraviolet layer, a microwave radiation blocking layer, an antibacterial layer, and a waterproof layer.

[0013] In a further technical solution, the aging-resistant layer is a cured epoxy resin adhesive layer with a thickness of 0.1-0.18 mm.

[0014] In a further technical solution, the glass fiber layer is made of ECR ​​glass fiber impregnation molding, with a thickness of 0.5mm-1.5mm and a tensile strength of 2200-2500Mpa.

[0015] In a further technical solution, the waterproof layer is located at the bottom opening of the cover, and the waterproof layer is made of acrylic waterproof coating. The waterproof layer is evenly distributed at least at the joint between the cover and the connecting seat.

[0016] The advantages of this invention compared to the prior art after adopting the above structure are:

[0017] 1. The connection between the connector and the base is secured by both threaded and snap-fit ​​connections, ensuring ease of assembly while avoiding the loosening issues that may occur with simple threaded connections due to vibration. At the same time, the connector and the cover are fixed by positioning with a limit ring and by filling the slot with silicone building sealant, further enhancing the sealing performance between the cover and the connector. This effectively prevents the intrusion of external moisture and acid / alkali corrosive media, significantly improving the overall corrosion resistance of the structure.

[0018] 2. The chamfered design at the top of the mounting opening in the center of the base can serve as a wedge positioning structure, facilitating quick alignment and assembly of the antenna or other equipment with the base; multiple connecting tubes on the top surface can be used to directly install other components, and the side connecting parts are fixed with bolts through holes, providing diverse installation methods to adapt to the installation needs of different scenarios and improve the adaptability and practicality of the radome.

[0019] 3. The radome is constructed from the outside in, consisting of a radome layer, an aging-resistant layer, a fiberglass layer, an anti-ultraviolet layer, a microwave radiation blocking layer, an antibacterial layer, and a waterproof layer, forming a multi-layered protective structure. It possesses multiple functions such as corrosion resistance, aging resistance, radiation resistance, antibacterial properties, and waterproofing, significantly extending the service life of the radome and internal antenna components in harsh environments.
