Abstract
Description
Technical Field
[0001] This utility model relates to the field of shipborne navigation technology, specifically to an anti-interference shipborne navigation antenna installation structure. Background Technology
[0002] Anti-interference shipborne navigation antennas are core equipment for ensuring accurate positioning of ships in complex electromagnetic environments. They effectively resist various interference signals, ensuring stable operation of the navigation system. Their core value is reflected in two main scenarios. First, they cope with complex electromagnetic environments, resisting electromagnetic interference generated by the ship's own equipment, surrounding vessels, and shore facilities, preventing positioning signal interference. Second, they adapt to harsh sea conditions, possessing waterproof, salt spray-proof, and vibration-resistant characteristics, enabling continuous operation in environments with strong winds, large waves, and high temperatures and humidity. Technically, this relies primarily on two methods: multi-beam reception technology, receiving signals through multiple antenna elements, automatically filtering valid signals and eliminating interference signals; and interference suppression algorithms, analyzing and processing the received mixed signals to accurately identify and suppress interference sources, ensuring the purity and stability of the navigation signal.
[0003] Chinese Utility Model Patent Publication No. CN215771519U discloses a shipborne satellite navigation antenna. The specification of this antenna states that an adjustment rod, driven by a motor inside a motor housing, can rotate to adjust the receiving direction of a metal parabolic surface. A motor inside a base rotates the motor housing, allowing for omnidirectional adjustment of the metal parabolic surface's signal reception direction. A first and second cleaning ring, secured to the edge of the metal parabolic surface, can rotate and clean the upper and lower surfaces. However, this shipborne satellite navigation antenna lacks a proper mounting structure for the antenna body, making it inconvenient to repair or replace after prolonged use. Furthermore, the lack of a reinforced mounting structure means the mounting frame is prone to deformation under prolonged rough and swaying conditions, resulting in poor practicality and hindering widespread adoption. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide an anti-interference shipborne navigation antenna installation structure. It can effectively solve the problems in the prior art, which does not have an installation structure for the navigation antenna body, making it inconvenient to repair or replace it after long-term use, and does not have a reinforced structure for the fixing frame. In the long-term turbulent and swaying environment of the ship, the fixing frame is prone to deformation, resulting in poor practicality and inconvenience for widespread use.
[0005] The technical solution adopted by this utility model is: an installation structure for an anti-interference shipborne navigation antenna, including a support frame and a protective cover. A guide block and an insert block are fixedly installed on one end of the support frame near the protective cover. A through hole is formed on the one end of the support frame near the protective cover. An installation groove is formed on the outer wall of the guide block, and a sealing ring is provided on the inner wall of the installation groove. A guide groove, a slot, and a through hole are formed on the one end of the protective cover near the support frame. A screw is inserted into the outer wall of the protective cover, and a nut is threaded onto the outer wall of the screw. An installation frame is fixedly installed on one end of the support frame near the protective cover. A threaded hole is formed on the side of the installation frame away from the support frame. A positioning block and a positioning block are fixedly installed on the side of the installation frame away from the support frame. A fixing frame is provided on the one end of the installation frame away from the support frame. A navigation antenna body is provided on the one end of the fixing frame away from the installation frame. A positioning groove, a positioning groove, and a threaded hole are formed on the one end of the fixing frame near the installation frame. A bolt is threaded onto the one end of the fixing frame near the installation frame. A reinforcing rod is fixedly installed on the outer wall of the fixing frame.
[0006] Preferably, the first positioning block and the first positioning groove are connected by a plug-in joint, and the second positioning block and the second positioning groove are connected by a plug-in joint.
[0007] Using the above technical solution, the staff inserts positioning block one into positioning slot one and positioning block two into positioning slot two, which enables rapid positioning of the navigation antenna body.
[0008] Preferably, the bolt extends through the second threaded hole into the interior of the first threaded hole, and the second threaded hole has the same diameter as the first threaded hole.
[0009] With the above technical solution, after the navigation antenna body is quickly positioned, the staff can insert the bolt through the second threaded hole and extend it into the first threaded hole, which can quickly fix the navigation antenna body. After long-term use, it is convenient to repair or replace it.
[0010] Preferably, the reinforcing rod is inclined, the cross-section of the fixing frame is U-shaped, and the cross-section of the combination of the reinforcing rod and the fixing frame is triangular.
[0011] Through the above technical solution, the design of the reinforcing rod, due to the stability of the triangular structure, can prevent the fixing frame from bending or breaking due to concentrated force, ensuring the installation stability of the navigation antenna body, improving the fatigue resistance of the overall structure, and adapting to the long-term use requirements of ships in turbulent and swaying environments.
[0012] Preferably, the guide block and the guide groove are plugged in, the plug block and the slot are plugged in, and the screw passes through through hole two and through hole one, with the two through holes having the same diameter.
[0013] Using the above technical solution, the staff inserts the guide block into the guide groove and the insert block into the slot. Then, the screw passes through the second through hole and the first through hole. Finally, the nut is threaded onto the screw, which enables the quick installation of the protective cover and facilitates its quick disassembly and assembly during use or assembly.
[0014] Preferably, the sealing ring is made of rubber, and three identical sealing rings are provided, with the three sealing rings distributed at equal intervals.
[0015] The above technical solution utilizes a sealing ring made of rubber material, which has excellent elasticity and sealing performance. This effectively prevents seawater, rainwater, fog, and dust from entering the protective cover, avoiding short circuits, signal interference, or performance degradation of the navigation antenna body due to moisture or dust accumulation. It meets the usage requirements of ships in high humidity and high salt spray environments at sea and is highly practical.
[0016] Preferably, the protective cover is made of fiberglass and has a streamlined design.
[0017] Through the above technical solutions, the protective cover made of fiberglass has the characteristics of high strength, corrosion resistance, and aging resistance. It can resist the salt spray corrosion, ultraviolet radiation, and wind and wave impact in the marine environment, and prevent the protective cover from rusting and cracking due to long-term exposure to the outdoors. At the same time, compared with metal materials, fiberglass is lighter, which can reduce the load on the support frame, reduce the overall counterweight pressure of the ship, and facilitate installation and maintenance. The streamlined design of the protective cover can reduce the turbulence on the surface of the protective cover, reduce the impact of wind and waves on the protective cover, further improve the stability of the protective cover, and indirectly ensure the signal reception stability of the internal navigation antenna.
[0018] Compared with the prior art, this utility model provides an anti-interference shipborne navigation antenna mounting structure, which has the following beneficial effects: 1. The installation structure of this anti-interference shipborne navigation antenna, through the design of positioning block one and positioning slot one and positioning block two and positioning slot two, enables rapid positioning of the navigation antenna body. Combined with bolts, threaded hole two and threaded hole one, rapid fixing of the navigation antenna body is achieved. After prolonged use, it facilitates maintenance or replacement. The design of the reinforcing rod, due to the stability of the triangular structure, prevents the fixing frame from bending or breaking due to concentrated force, ensuring the installation stability of the navigation antenna body and improving the fatigue resistance of the overall structure, adapting to the long-term use requirements of ships in turbulent and swaying environments. The cooperation of guide block and guide slot, insert block and slot, screw, through hole two, through hole one and nut enables rapid installation of the protective cover, facilitating quick assembly and disassembly during use or assembly.
[0019] 2. The installation structure of this anti-interference shipborne navigation antenna uses a sealing ring made of rubber material, which has excellent elasticity and sealing performance. It effectively prevents seawater, rainwater, fog and dust from entering the protective cover, avoiding short circuits, signal interference or performance degradation of the navigation antenna body due to moisture and dust accumulation. It meets the usage requirements of ships in the high humidity and high salt spray environment of the ocean and has high practicality. The protective cover made of fiberglass has the characteristics of high strength, corrosion resistance and aging resistance. It can resist the salt spray corrosion, ultraviolet radiation and wind and wave impact in the marine environment, preventing the protective cover from rusting and cracking due to long-term exposure to the outdoors. At the same time, compared with metal materials, fiberglass is lighter, which can reduce the load on the support frame, reduce the overall counterweight pressure of the ship, and facilitate installation and maintenance.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example 1: like Figure 1-6As shown, the present invention provides an installation structure for an anti-interference shipborne navigation antenna, comprising a support frame 1 and a protective cover 2. A guide block 3 and an insert block 4 are fixedly installed at one end of the support frame 1 near the protective cover 2. A through hole 5 is provided at one end of the support frame 1 near the protective cover 2. An installation groove 6 is provided on the outer wall of the guide block 3, and a sealing ring 7 is provided on the inner wall of the installation groove 6. A guide groove 8, a slot 9, and a through hole 10 are provided at one end of the protective cover 2 near the support frame 1. A screw 11 is inserted into the outer wall of the protective cover 2, and a nut 12 is threaded onto the outer wall of the screw 11. The support frame 1 is fixed at one end near the protective cover 2. A mounting bracket 13 is installed. A threaded hole 15 is provided on the side of the mounting bracket 1 away from the support bracket 1. A positioning block 23 and a positioning block 24 are fixedly installed on the side of the mounting bracket 13 away from the support bracket 1. A fixing bracket 17 is provided at the end of the mounting bracket 13 away from the support bracket 1. A navigation antenna body 16 is provided at the end of the fixing bracket 17 away from the mounting bracket 13. A positioning groove 18, a positioning groove 29 and a threaded hole 20 are provided at the end of the fixing bracket 17 near the mounting bracket 13. A bolt 21 is threadedly connected to the end of the fixing bracket 17 near the mounting bracket 13. A reinforcing rod 22 is fixedly installed on the outer wall of the fixing bracket 17.
[0024] Specifically, positioning block 23 and positioning slot 18 are connected by a plug-in joint, and positioning block 24 and positioning slot 29 are also connected by a plug-in joint. The advantage is that by inserting positioning block 23 into positioning slot 18 and positioning block 24 into positioning slot 29, the navigation antenna body 16 can be quickly positioned.
[0025] Specifically, bolt 21 extends through threaded hole 20 into threaded hole 15, and threaded hole 20 and threaded hole 15 have the same diameter. The advantage is that after the navigation antenna body 16 is quickly positioned, the operator can quickly fix the navigation antenna body 16 by extending bolt 21 through threaded hole 20 into threaded hole 15. After long-term use, it is convenient to inspect or replace it.
[0026] Specifically, the reinforcing rod 22 is inclined, the cross-section of the fixing frame 17 is U-shaped, and the combined cross-section of the reinforcing rod 22 and the fixing frame 17 is triangular. The advantage is that the design of the reinforcing rod 22, due to the stability of the triangular structure, prevents the fixing frame 17 from bending or breaking due to concentrated stress, ensuring the installation stability of the navigation antenna body 16, improving the fatigue resistance of the overall structure, and adapting to the long-term use requirements of ships in turbulent and swaying environments.
[0027] Example 2: like Figure 2-6As shown, as an improvement on the previous embodiment, to further facilitate the installation of the protective cover 2, specifically, the guide block 3 and the guide groove 8 are plugged in, the insert block 4 and the slot 9 are plugged in, and the screw 11 passes through the second through hole 10 and the first through hole 5, with the same diameter. The advantage is that the operator inserts the guide block 3 into the guide groove 8, simultaneously inserts the insert block 4 into the slot 9, then inserts the screw 11 through the second through hole 10 and the first through hole 5, and finally threads the nut 12 onto the screw 11, enabling rapid installation of the protective cover 2 and facilitating quick assembly and disassembly during use or assembly.
[0028] Specifically, the sealing ring 7 is made of rubber, and three identical sealing rings 7 are arranged at equal intervals. The advantage is that the rubber sealing ring 7 has excellent elasticity and sealing performance, effectively preventing seawater, rainwater, fog, and dust from entering the protective cover 2. This avoids short circuits, signal interference, or performance degradation of the navigation antenna body 16 due to moisture or dust accumulation, making it suitable for use in high-humidity, high-salt-fog marine environments and highly practical.
[0029] Specifically, the protective cover 2 is made of fiberglass and features a streamlined design. The advantages of using fiberglass are that it offers high strength, corrosion resistance, and anti-aging properties, enabling it to withstand salt spray corrosion, ultraviolet radiation, and wave impact in the marine environment. This prevents the protective cover 2 from rusting and cracking due to long-term outdoor exposure. Furthermore, compared to metal, fiberglass is lighter, reducing the load on the support frame 1 and lowering the overall weight distribution of the ship. It is also easier to install and maintain. The streamlined design of the protective cover 2 reduces surface turbulence, minimizing the impact of waves and further enhancing its stability, indirectly ensuring the signal reception stability of the internal navigation antenna 16.
[0030] Working Principle: During installation, the operator inserts positioning block 23 into positioning slot 18 and positioning block 24 into positioning slot 19, enabling rapid positioning of the navigation antenna body 16. After positioning the navigation antenna body 16, the operator inserts bolt 21 through threaded hole 20 into threaded hole 15, quickly fixing the navigation antenna body 16 and facilitating maintenance or replacement after prolonged use. Then, the operator inserts guide block 3 into guide slot 8 and inserts block 4 into slot 9. Next, screw 11 passes through through hole 10 and through hole 5, and finally, nut 12 is threaded onto screw 11, enabling rapid installation of the protective cover 2 and facilitating quick disassembly and assembly during use or assembly. During use, the design of reinforcing rod 22, with its triangular structure, provides stability and prevents bending or breakage of the fixing frame 17 due to concentrated stress, ensuring the installation stability of the navigation antenna body 16 and improving the overall structure's fatigue resistance. To meet the needs of ships operating in turbulent and swaying environments for extended periods, the protective cover 2, made of fiberglass, features high strength, corrosion resistance, and anti-aging properties. It can withstand salt spray corrosion, ultraviolet radiation, and wave impact in the marine environment, preventing rust and cracking due to prolonged outdoor exposure. Furthermore, compared to metal, fiberglass is lighter, reducing the load on the support frame 1 and lowering the overall weight distribution of the ship. It is also easier to install and maintain. The streamlined design of the protective cover 2 reduces surface turbulence, mitigating the impact of waves and further enhancing its stability. This indirectly ensures the signal reception stability of the internal navigation antenna 16. The rubber sealing ring 7 provides excellent elasticity and sealing, effectively preventing seawater, rainwater, fog, and dust from entering the protective cover 2. This prevents short circuits, signal interference, or performance degradation of the navigation antenna 16 due to moisture or dust accumulation. It is well-suited for use in high-humidity, high-salt-spray marine environments and is highly practical.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
