Description

Technical Field

[0001] This utility model specifically relates to a waterproof and sealed radar transceiver signal transceiver antenna structure and a radar transceiver. Background Technology

[0002] A radar transponder is an important navigational aid, typically installed on buoys, lighthouses, or fixed offshore platforms. When it receives a radar signal in a specific frequency band emitted by a shipborne radar, it immediately transmits a coded response signal back to the radar, displaying the transponder's identification code and precise location symbol on the radar screen. This greatly enhances the safety and reliability of ship navigation.

[0003] The antenna is the core component of a radar transponder, enabling signal transmission and reception. Its performance directly determines the effective range and signal quality of the transponder. Since radar transponders operate in harsh marine environments, they are inevitably exposed to severe conditions such as high humidity, salt spray, rain, and even direct wave impact. Therefore, the antenna's waterproof and sealing performance is crucial for ensuring the long-term stable operation of the entire device and extending its service life.

[0004] Currently, most common radar transponder antenna structures use O-rings or sealant to seal the shell joint surfaces. However, under long-term exposure to wind, sun, temperature cycles, and mechanical vibration, O-rings are prone to aging, permanent compression deformation, and loss of elasticity, leading to seal failure; sealant also carries the risk of aging and cracking. Once the seal fails, moisture and salt spray can penetrate the antenna, causing corrosion and short circuits in critical components such as circuit boards and RF connectors, resulting in the entire transponder malfunctioning. Furthermore, to achieve effective sealing, some antenna structures are designed to be quite complex, employing multi-layered shells, multiple fasteners, and multiple sealing processes. This not only increases the difficulty and cost of production and assembly but also greatly inconveniences subsequent maintenance and repair.

[0005] Therefore, it is necessary to invent a waterproof and sealed radar transponder signal transceiver antenna structure and a radar transponder to solve the above problems. Utility Model Content

The top of the docking sleeve is provided with a sealing groove, and the upper part of the inner wall of the docking sleeve is provided with a threaded groove. The sealing cover is installed on the top of the signal transceiver antenna column. Its bottom outer wall is provided with a thread two that matches the thread groove two. The upper end of the thread two is provided with a thread three that matches the thread groove three. Below the thread three, there is a sealing groove four that matches the sealing groove one.

A sealing ring 1 is installed between sealing groove 1 and sealing groove 4, a sealing ring 2 is installed in sealing groove 2, and a sealing ring 3 is installed between sealing groove 3 and sealing groove 5.

[0008] Preferably, the docking sleeve is fitted onto the outer wall of the top of the signal transceiver antenna column, and the first thread on its inner wall matches and is tightened with the first thread groove. The second sealing ring is attached to the inner wall of the docking sleeve, and the outer wall of the docking sleeve is provided with multiple anti-slip textures, which are arranged in a ring around the outer wall of the docking sleeve.

[0009] Preferably, the tightening direction of the mating sleeve and the sealing cap is the same, and the internal dimensions of the sealing groove three at the top of the mating sleeve are the same as the internal dimensions of the sealing groove five.

[0018] This utility model provides, for example Figure 1-4 The waterproof and sealed radar transceiver signal transceiver antenna structure shown includes a signal transceiver antenna column 1, a docking sleeve 2 installed on the top of the signal transceiver antenna column 1, the docking sleeve 2 being disposed on the outer wall of the top of the signal transceiver antenna column 1, and a sealing cover 3 installed inside the docking sleeve 2, the sealing cover 3 being connected to the inner wall of the docking sleeve 2 and the inner wall of the signal transceiver antenna column 1. In this embodiment, the top of the signal transceiver antenna column 1 is provided with a sealing groove 11, the outer wall is provided with a sealing groove 12, the bottom of the sealing groove 12 is provided with a threaded groove 13, and the inner wall of the top of the signal transceiver antenna column 1 is provided with a threaded groove 14. Specifically, the docking sleeve 2 is fitted on the top outer wall of the signal transceiver antenna column 1, and the lower part of the inner wall of the docking sleeve 2 is provided with a matching thread groove 13 with a thread 21, the top of the docking sleeve 2 is provided with a sealing groove 22, and the upper part of the inner wall of the docking sleeve 2 is provided with a thread groove 23. Specifically, the sealing cover 3 is installed on the top of the signal transceiver antenna column 1. Its bottom outer wall is provided with a thread 31 matching the thread groove 14. The upper end of the thread 31 is provided with a thread 32 matching the thread groove 23. The lower part of the thread 32 is provided with a sealing groove 4 33 matching the sealing groove 11. The upper part of the thread 32 is provided with a knob 34. The bottom of the knob 34 is provided with a sealing groove 5 35 matching the sealing groove 22. Specifically, a sealing ring 4 is installed between sealing groove 11 and sealing groove 43, a sealing ring 5 is installed in sealing groove 22, and a sealing ring 6 is installed between sealing groove 32 and sealing groove 535.

[0019] Specifically, the docking sleeve 2 is fitted onto the top outer wall of the signal transceiver antenna column 1, and its inner wall thread 21 matches and is tightened with the thread groove 13. The sealing ring 5 is attached to the inner wall of the docking sleeve 2. The outer wall of the docking sleeve 2 is provided with multiple anti-slip textures 24, which are arranged in a ring around the outer wall of the docking sleeve 2.

[0020] Specifically, the tightening directions of the mating sleeve 2 and the sealing cover 3 are the same, and the internal dimensions of the sealing groove 32 on the top of the mating sleeve 2 are the same as the internal dimensions of the sealing groove 535.

[0021] Specifically, the bottom thread 31 of the sealing cap 3 matches and is tightened with the thread groove 14. After the two are aligned, the thread 32 matches and corresponds with the thread groove 23.

[0022] Specifically, the outer wall of the knob 34 on the top of the sealing cover 3 is provided with multiple tightening grooves 36.

[0023] In this embodiment, before installation, the surfaces of each component should be cleaned with a lint-free cloth, focusing on wiping the threaded grooves and sealing grooves of the signal transceiver antenna column 1, the inner wall and threads of the mating sleeve 2, and the threads and sealing grooves of the sealing cover 3, to remove oil, dust and other impurities; at the same time, check whether the sealing ring is damaged or deformed, and replace it in time if there is a problem to avoid affecting the sealing effect.

[0024] Specifically, place the sealing ring 25 into the sealing groove 22 of the signal transceiver antenna column 1, and gently press along the edge of the sealing ring with your finger to ensure that the sealing ring is fully embedded in the groove without any protrusion or misalignment. Then, hold the docking sleeve 2 and align the threaded end 21 with the top of the column, and slowly slip it onto the outer wall. When the threaded end 21 contacts the threaded groove 13, rotate the docking sleeve 2 clockwise. During the rotation, apply force with your fingers against the anti-slip texture 24 to avoid slipping, and continue to tighten until the lower end face of the docking sleeve 2 is in contact with the stepped surface of the column. At this time, the sealing ring 25 is squeezed between the inner wall of the docking sleeve and the outer wall of the column, forming a preliminary outer wall seal.

[0025] Specifically, continue to tighten the sealing cap 3 until the bottom of the knob 34 fits against the top of the mating sleeve 2. At this time, the sealing ring 4 is squeezed between the sealing groove 11 and the sealing groove 33, and the sealing ring 6 is squeezed between the sealing groove 22 and the sealing groove 35. Finally, use a wrench to insert into the tightening groove 36 of the knob 34 and apply a slight torque to reinforce it, ensuring that all threads are tightened without loosening and that the sealing rings are not exposed or deformed, thus completing the overall assembly.

[0026] In this embodiment, the sealing ring is installed between the signal transceiver antenna column 1 and the sealing cover 3. After the sealing cover is tightened, the sealing groove 11 and the sealing groove 33 form a bidirectional compression between the upper and lower parts, causing it to undergo elastic deformation, filling all the gaps in the groove and tightly fitting the groove wall and end face, forming a transverse sealing barrier to prevent moisture and water vapor from entering from the core connection part, thus protecting the key components such as the signal module and circuit inside the antenna.

[0027] In this embodiment, the inner wall of the inner wall of the signal transceiver antenna column 1 and the docking sleeve 2 are located between the signal transceiver antenna column 1 and the docking sleeve 2. After the docking sleeve is tightened, the outer wall of the inner wall of the column forms radial compression on the sealing ring. After the sealing ring is elastically deformed, it fits tightly against the surfaces of both, forming a longitudinal sealing barrier to prevent moisture from seeping in from the gaps in the outer wall. At the same time, it blocks dust and impurities from entering the threaded connection part, avoiding thread corrosion and jamming.

[0028] In this embodiment, the sealing ring is installed between the docking sleeve 2 and the sealing cover 3. After the sealing cover is tightened, the bottom of the knob and the top of the docking sleeve exert axial pressure on the sealing ring. After the sealing ring is deformed, it fills the gap of the sealing groove, forming a third sealing barrier. Together with the first two sealing rings, it forms a three-dimensional protection, which greatly improves the overall waterproof performance.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
