Abstract
Description
Technical Field
[0001] This utility model relates to the field of antenna protection structures, and in particular to a direction-finding antenna protection structure that can be quickly disassembled. Background Technology
[0002] As the core component of a radio direction finding system, the performance stability and service life of the direction finding antenna are directly related to the reliable operation of the entire system. In practical application environments, direction finding antennas are often exposed outdoors and are affected by various external factors such as wind, rain, and impacts from foreign objects, which can easily cause damage to the antenna structure or signal interference.
[0003] Therefore, it is usually necessary to install a protective structure on it to ensure its normal operation and extend its service life.
[0004] However, conventional direction-finding antenna protection structures often employ fixed or complex assembly methods, which present problems such as inconvenient disassembly and difficult maintenance. Furthermore, direction-finding antennas are often installed in mountainous areas, where strong winds can easily blow down surrounding tree branches and leaves. When tree branches, leaves, and other foreign objects impact the protection structure, the lack of buffering devices in conventional protection structures can damage the structure, affecting its service life. Moreover, the impact force can be transmitted to the direction-finding antenna, easily causing damage to it. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a quick-disassembly direction-finding antenna protection structure, which aims to improve the problems of conventional protection structures in the prior art being inconvenient to disassemble and maintain, lacking buffer devices, and easily damaged by impacts from external objects in mountainous areas, with the impact force being transmitted to the antenna and causing damage.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a quick-detachable direction-finding antenna protection structure, including a mounting base, a direction-finding antenna fixedly mounted on the upper surface of the mounting base by bolts, and a protective component provided on the outside of the direction-finding antenna; The protective assembly includes a mounting ring, which is fixedly mounted on the upper surface of the mounting base by bolts. A support rod is provided above the mounting base. A slot is provided at the bottom end of the outer wall of the support rod, and a slot is provided at the rear end of the outer wall of the support rod. A mounting frame is sleeved on the rear end of the outer wall of the support rod, and a locking block is fixedly connected to the lower surface of the mounting frame. A buffer assembly is provided on the outer wall of the support rod. The mounting ring is inserted into the inner wall of the slot, and the locking block is inserted into the inner wall of the slot.
[0007] As a further description of the above technical solution: The buffer assembly includes a guide groove, which is formed on the outer wall of the support rod. A rotating shaft is rotatably connected to the inner surface of the guide groove, and a roller is rotatably connected to the inner surface of the rotating shaft. A sleeve is hinged to the outer wall of the roller. A slide rod is elastically connected to the inner wall of the sleeve near the rotating shaft through an elastic element. A protective plate is hinged to the end of the slide rod away from the elastic element.
[0008] As a further description of the above technical solution: the support rod is set in an L-shape.
[0009] As a further description of the above technical solution: there are two sets of mounting frames, which are symmetrically distributed vertically, and the two sets of mounting frames are fixed together by bolts.
[0010] As a further description of the above technical solution: multiple sets of rollers are provided, and the multiple sets of rollers are arranged in a circular array with the center point of the rotating shaft as the origin.
[0011] As a further description of the above technical solution: the slide rod passes through and is slidably connected to the end of the sleeve away from the rotating shaft.
[0012] As a further description of the above technical solution: the outer wall of the protective plate is fixedly connected with a buffer pad.
[0013] This utility model has the following beneficial effects: 1. In this utility model, with the cooperation of the protective component, the support rod can be disassembled and assembled simply by removing the bolts that fix the two sets of mounting frames, which facilitates the maintenance of the direction-finding antenna. During installation, the support rod can be fixed by simply inserting the clip and the slot, and then fixing the two sets of mounting frames with bolts. Then, the protective component can be installed by fixing the mounting ring. The disassembly and assembly are convenient, which improves the convenience of the device.
[0014] 2. In this utility model, with the cooperation of the buffer components, when an external object impacts, it is first buffered by the buffer pad, and then the elastic element is squeezed by the slide rod to release the force a second time. At the same time, the roller and the rotating shaft convert part of the impact force into the kinetic energy of rotation, weakening the transmission of impact force, avoiding damage to the protective structure due to lack of buffer, and also protecting the direction finding antenna from the impact force, thus extending the service life of both.

[0017] 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.
[0018] Reference Figures 1-3 This utility model provides an embodiment of a quick-detachable direction-finding antenna protection structure, including a mounting base 1 for supporting the overall device. The mounting base 1 can be welded or fixed to the ground or supporting equipment using bolts to ensure the stability of the device. A direction-finding antenna 2 is fixedly mounted on the upper surface of the mounting base 1 by bolts. The direction-finding antenna 2 is prior art and can be implemented by those skilled in the art. Since it is prior art, it will not be described in detail in this case. The direction-finding antenna 2 is located in the middle position on the mounting base 1. A protective component is provided on the outside of the direction-finding antenna 2 to protect the direction-finding antenna 2.
[0019] Reference Figures 2-4The protective assembly includes a mounting ring 35, which is semi-circular in shape. The mounting ring 35 is bolted to the upper surface of the mounting base 1. Two sets of mounting rings 35 are provided, and the two sets can be assembled into a circular ring, with the assembled ring aligned with the center of the mounting base 1. A support rod 32 is provided above the mounting base 1. Multiple sets of support rods 32 are arranged in a circular array with the center point of the mounting base 1 as the origin. A slot 36 is provided at the bottom end of the outer wall of the support rod 32. The inner surface of the mounting ring 35 is raised, and the raised portion and the slot... The support rod 32 has a slot 33 at its rear end. The slots 33 are symmetrically distributed on the upper and lower surfaces of the rear end of the support rod 32. The support rod 32 has a mounting frame 31 sleeved on its rear end. The mounting frame 31 has a locking block 34 fixedly connected to its lower surface. The locking block 34 and the slot 33 fit together. The support rod 32 has a buffer component on its outer wall. The buffer component can reduce the impact force of external impact. The mounting ring 35 is inserted into the inner wall of the slot 36. The mounting ring 35 can limit the movement of multiple sets of support rods 32. The locking block 34 is inserted into the inner wall of the slot 33.
[0020] Reference Figures 2-4 The support rod 32 is L-shaped, and there are two sets of mounting frames 31. The two sets of mounting frames 31 are symmetrically distributed vertically, and the two sets of mounting frames 31 are fixed together by bolts. The two sets of mounting frames 31 can fix multiple sets of support rods 32, so that the multiple sets of support rods 32 wrap around the direction finding antenna 2 in a birdcage shape, providing it with protection.
[0021] Reference Figure 2 , Figure 4 , Figure 6 The buffer assembly includes a guide groove 48, which is formed on the outer wall of the support rod 32. A rotating shaft 41 is rotatably connected to the inner surface of the guide groove 48. The contact area between the rotating shaft 41 and the guide groove 48 is small. A roller 47 is rotatably connected to the inner surface of the rotating shaft 41. The roller 47 and the rotating shaft 41 are in direct contact, which can reduce the friction during rotation. A sleeve 42 is hinged to the outer wall of the roller 47. The sleeve 42 is hollow inside and can rotate around the hinge point. A sliding rod 44 is elastically connected to the inner wall of the sleeve 42 near the rotating shaft 41 through an elastic element 43. A protective plate 45 is hinged to the end of the sliding rod 44 away from the elastic element 43. The protective plate 45 is cylindrical and wraps around the support rod 32.
[0022] Reference Figures 4-6Multiple sets of rollers 47 are arranged in a circular array with the center point of the rotating shaft 41 as the origin. The sliding rod 44 passes through and is slidably connected to the end of the sleeve 42 away from the rotating shaft 41. When the sliding rod 44 slides along the trajectory of the sleeve 42, it will squeeze or stretch the elastic element 43 to generate a reaction force. When an external force comes, the rollers 47 and the rotating shaft 41 can rotate to relieve the impact. The outer wall of the protective plate 45 is fixedly connected to the buffer pad 46. The buffer pad 46 is made of flexible and wear-resistant material and can provide initial buffering when an external object hits. Commonly hit external objects include tree branches blown down by strong winds. Some of the direction finding antennas 2 are installed on mountains, where there are often fallen leaves and blown branches. The birdcage-shaped support rod 32 can block branches and leaves, and the buffer assembly can withstand the impact of external objects to ensure the service life of the device.
[0023] Working principle: First, fix the mounting base 1 on the ground or supporting equipment to ensure stability. Then, use bolts to fix the direction finding antenna 2 on the mounting base 1 to ensure that the direction finding antenna 2 is installed stably.
[0024] Then, take two sets of symmetrical mounting frames 31 and fit them onto the outer walls of the multiple sets of support rods 32 respectively, so that the locking blocks 34 align with the locking slots 33. Insert the locking blocks 34 into the inner wall of the locking slots 33, and then fix the two sets of mounting frames 31 with bolts. At this time, the multiple sets of support rods 32 are fixed by the mounting frames 31 into a "birdcage" structure. Then, fit the support rods 32 onto the outside of the direction finding antenna 2, and assemble the mounting rings 35 into a complete circular shape. Make the mounting rings 35 and the slots 36 fit together to limit the position of the support rods 32, and use bolts to fix the mounting rings 35 to the mounting base 1. At this time, the support rods 32 will be fixed, providing protection for the direction finding antenna 2.
[0025] When an external object impacts the object, the buffer pad 46 on the outer wall of the protective plate 45 first contacts the object. The flexible deformation of the buffer pad 46 absorbs part of the impact force, achieving initial buffering. If the impact force continues to be transmitted, the protective plate 45 pushes the slide rod 44 to slide along the inner wall of the sleeve 42. The slide rod 44 squeezes and stretches the elastic element 43. The elastic element 43 further offsets the impact force through deformation. At the same time, the roller 47 and the rotating shaft 41 rotate along the guide groove 48, converting part of the impact force into rotational kinetic energy, reducing the impact of the direct impact force on the support rod 32 and the direction finding antenna 2, and finally achieving all-round buffer protection for the direction finding antenna 2.
[0026] When it is necessary to disassemble the protective structure, first unscrew the fixing bolts between the two sets of mounting frames 31, remove the two sets of mounting frames 31, then separate the slot 36 from the mounting ring 35, remove the multiple sets of support rods 32, finally unscrew the connecting bolts between the mounting ring 35 and the mounting base 1, disassemble the two sets of mounting rings 35 and remove them, and the direction finding antenna 2 can be exposed for maintenance or replacement, thus completing the disassembly operation.
[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
