Description

Technical Field

[0001] This utility model relates to the field of radar dome technology, specifically to a radar dome that is easy to maintain. Background Technology

[0002] In the field of modern radar technology, the radome is a key component that protects the radar antenna system from the influence of the external environment. Its performance and reliability are of paramount importance. However, the existing radomes are cumbersome to install and disassemble. Moreover, the radomes are located in dusty outdoor environments, such as desert areas, near construction sites, or along busy highways. A large number of dust particles may enter the radome, and the accumulation of dust on the radar equipment may interfere with the transmission and reception of radar signals. Furthermore, in areas prone to extreme weather, such as places with frequent heavy rain, blizzards, and hail, the radomes are easily damaged by impacts from hail. To solve the above problems, a radome that is easy to maintain is needed.

[0003] Existing radomes are susceptible to damage during operation. Dust particles may enter the radome and interfere with the transmission and reception of radar signals. They are also prone to cracking and denting when subjected to significant impacts, such as high-speed bird strikes, collisions with out-of-control small drones, or impacts from hard objects carried by strong winds. Furthermore, some radomes use numerous bolts and rivets to fasten various components together, making the disassembly of these connecting parts extremely cumbersome when maintenance is required, such as internal equipment repairs or replacement of damaged radome components. Therefore, there is an urgent need for a radome that is easier to maintain. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a radome that is easy to maintain, in order to solve the problems of existing radomes, such as dust particles entering the radome during use and interfering with the transmission and reception of radar signals; when faced with large impacts, such as high-speed bird strikes, collisions with small uncontrolled drones, or impacts from hard objects carried by strong winds, they are prone to cracking, dents and other damage; and some radomes use a large number of bolts, rivets and other connection methods to fix various components together, which makes it extremely cumbersome to disassemble these connecting components when maintenance of the radome is required, such as internal equipment repair or replacement of damaged radome components.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a radar dome that is easy to maintain, comprising a radar dome, wherein a dustproof net is installed on the inner wall of the radar dome, a limit spring is installed on the inner wall of the dustproof net, and a limit lever is installed on the outer wall of the limit spring.

[0006] The side wall of the radar dome is equipped with a locking block, the outer wall of the radar dome is equipped with a fixing frame, the inner wall of the fixing frame is provided with a locking groove, a limiting rod passes through the interior of the fixing frame, and a limiting sleeve is installed on the outer wall of the limiting rod.

[0007] The outer wall of the radar dome is fitted with a fixing ring, and the outer wall of the fixing ring is fitted with a protective railing.

[0008] Preferably, the outer diameter of the dustproof net matches the inner diameter of the radome, and the dustproof net is movably connected to the radome.

[0009] Preferably, the limiting rod forms a telescopic structure with the dustproof net through the limiting spring, and the limiting rod is engaged with the radar dome.

[0010] Preferably, the card block engages with the card slot, and the card block is symmetrically arranged with the central axis of the radar dome as the center.

[0011] Preferably, the locking block is movably connected to the limiting rod, and the limiting rod is threadedly connected to the limiting sleeve.

[0012] Preferably, the guardrails are arranged in a circular array with the central axis of the fixed ring as the center, and the top of the guardrails is an elastic spherical shape.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the setting of a dustproof net, a limiting spring and a limiting rod, allows the limiting rod to be pressed inward and then placed in the appropriate position inside the radar dome. The limiting rod is then pushed out by the elastic force of the limiting spring, so that the limiting rod is locked and fixed to the radar dome. The setting of the dustproof net can prevent dust from entering the inside of the radar dome and causing damage to the internal components or interfering with the transmission and reception of radar signals.

[0015] 2. This utility model uses a set of card blocks, a fixing frame, card slots, a limiting rod, and a limiting sleeve to insert the card blocks on both sides of the radar dome into the card slots inside the fixing frame. Then, the radar dome is rotated 90 degrees, and the card slots position the card blocks. Finally, the radar dome is threadedly fixed by the limiting rod and the limiting sleeve, which is convenient for disassembly and assembly and facilitates subsequent maintenance.

[0016] 3. This utility model features a fixed ring and a protective railing. The fixed ring is welded to the outer wall of the radome, while the top of the protective railing is set in an elastic spherical shape. This provides a buffer protection against high-speed bird strikes, collisions from out-of-control small drones, or impacts from hard objects carried by strong winds, thus preventing direct impact damage to the radome body.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] The embodiments of this utility model will be described below based on its overall structure.

[0024] Please see Figure 1-4 A radome designed for easy maintenance includes a radome 1. A dustproof net 2 is installed on the inner wall of the radome 1. A limiting spring 3 is installed on the inner wall of the dustproof net 2, and a limiting rod 4 is installed on the outer wall of the limiting spring 3. The diameter of the outer wall of the dustproof net 2 matches the diameter of the inner wall of the radome 1, and the dustproof net 2 is movably connected to the radome 1. The limiting rod 4 forms a telescopic structure with the dustproof net 2 via the limiting spring 3, and is engaged with the radome 1. By pressing the limiting rod 4 inward and placing the dustproof net 2 into a suitable position inside the radome 1, the limiting rod 4 is pushed out by the elastic force of the limiting spring 3, thus engaging and fixing the limiting rod 4 with the radome 1. The dustproof net 2 prevents dust from entering the radome 1, thus avoiding damage to internal components or interference with radar signal transmission and reception.

[0025] Please see Figure 1-4A radome designed for easy maintenance includes a locking block 5 installed on the side wall of the radome 1, a fixing frame 6 installed on the outer wall of the radome 1, a locking groove 7 on the inner wall of the fixing frame 6, a limiting rod 8 penetrating the interior of the fixing frame 6, and a limiting sleeve 9 installed on the outer wall of the limiting rod 8. The locking block 5 engages with the locking groove 7, and the locking block 5 is symmetrically arranged around the central axis of the radome 1. The locking block 5 is movably connected to the limiting rod 8, and the limiting rod 8 is threadedly connected to the limiting sleeve 9. By using the locking block 5, fixing frame 6, locking groove 7, limiting rod 8, and limiting sleeve 9, the locking blocks 5 on both sides of the radome 1 are inserted into the locking groove 7 inside the fixing frame 6. Then, the radome 1 is rotated 90 degrees, the locking groove 7 positions the locking block 5, and then the radome 1 is threadedly fixed by the limiting rod 8 and the limiting sleeve 9. This design facilitates disassembly and assembly, and makes subsequent maintenance easier.

[0026] Please see Figure 1-4 A radome designed for easy maintenance is described. The outer wall of the radome 1 is fitted with a fixing ring 10, and the outer wall of the fixing ring 10 is fitted with a protective railing 11. The protective railing 11 is arranged in a circular array with the central axis of the fixing ring 10 as the center, and the top of the protective railing 11 is set in an elastic spherical shape. The fixing ring 10 is welded to the outer wall of the radome 1 through the fixed ring 10 and the protective railing 11. The top of the protective railing 11 is set in an elastic spherical shape, which plays a buffering protection role when subjected to high-speed bird impacts, collisions with small uncontrolled drones, or impacts with hard objects carried by strong winds, so as to avoid direct impact damage to the radome 1.

[0027] Working principle: In use, first move the device to the desired position, then insert the locking blocks 5 on both sides of the radar dome 1 into the locking slots 7 inside the fixing frame 6, then rotate the radar dome 1 90 degrees, the locking slots 7 position the locking blocks 5, and then fix the radar dome 1 with threads through the limiting rod 8 and the limiting sleeve 9, which is convenient for disassembly and assembly and subsequent maintenance. Then, by pressing the limiting rod 4 inward, and then placing the dustproof net 2 into the appropriate position inside the radar dome 1, the limiting rod 4 is pushed out by the elastic force of the limiting spring 3, so that the limiting rod 4 is locked and fixed with the radar dome 1. The dustproof net 2 can prevent dust from entering the inside of the radar dome 1, which may damage the internal components or interfere with the transmission and reception of radar signals. Finally, the top of the protective railing 11 is set with an elastic ball shape, which plays a buffering role when subjected to high-speed bird impacts, small drones going out of control, or hard objects carried by strong winds, preventing the radar dome 1 from being directly damaged by impact. This completes the use of the device. The contents not described in detail in this manual are existing technologies known to those skilled in the art.
