Description

Technical Field

[0001] This utility model relates to the technical field of antenna-assisted orientation, specifically to an auxiliary orientation device for a circularly polarized horn antenna. Background Technology

[0002] Circularly polarized horn antennas are widely used in satellite communications, radar telemetry, and other fields. Their performance is highly dependent on the precise alignment of the antenna's main axis. Traditional orientation adjustment methods typically rely on specialized instruments (such as spectrum analyzers and field strength meters) or manual experience, which is cumbersome and inefficient. Technicians need to repeatedly adjust the antenna's azimuth and elevation angles and indirectly judge the alignment by observing changes in signal strength. This method is not only time-consuming and labor-intensive but also greatly affected by the environment and personnel experience, making it difficult to achieve rapid and accurate initial positioning. Especially in field operations or situations requiring frequent adjustments, existing technology lacks an auxiliary means that can intuitively and quickly indicate the antenna's main axis direction. This leads to problems such as difficulty in initial alignment, long adjustment cycles, and difficulty in guaranteeing accuracy during antenna adjustment. Therefore, there is an urgent need for an auxiliary orientation device that is simple in structure, easy to operate, and can intuitively indicate the antenna axis. Utility Model Content

[0003] The purpose of this invention is to provide a circularly polarized horn antenna auxiliary orientation device. Through its unique mechanical structure combined with laser indication, it achieves fast, accurate and reliable antenna orientation assistance.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a circularly polarized horn antenna auxiliary directional device, comprising a circular ring, a cylindrical body disposed at the axial center of the circular ring, the cylindrical body being coaxially disposed with the circular ring, a fixing component disposed on the circular ring for fixing to the edge of the horn mouth of the circularly polarized horn antenna, and a laser light mounted on the cylindrical body, the emission direction of the laser light being consistent with the axial direction of the cylindrical body.

[0005] By setting up a ring, a cylinder, and a laser light coaxial with the horn of the circularly polarized horn antenna, a precise physical axis reference is provided, and this reference is extended outward in the form of a visible laser. This allows staff to intuitively and quickly aim and calibrate the main axis of the antenna, greatly improving the efficiency and accuracy of antenna azimuth adjustment.

[0006] In a further technical solution, the fixing component includes several hooks, connecting rods and sliding rods. One end of the connecting rod is fixedly connected to the hook, and the other end is fixedly connected to the sliding rod. The sliding rod is slidably disposed on the annular body, and the hook can move radially to adapt to different diameter flared mouths.

[0007] The sliding fixing assembly, consisting of hooks, connecting rods, and slide bars, allows the device to be mounted on the edge of the horn mouth of circularly polarized horn antennas of different diameters by adjusting the radial position of the hooks, significantly improving the versatility and applicability of the auxiliary directional device.

[0008] In a further technical solution, the annular body is provided with a plurality of sliding holes evenly distributed circumferentially along its axial direction, and the sliding rod is slidably inserted into the sliding holes.

[0009] By setting evenly distributed sliding holes on the annulus to guide the movement of the sliding rod, it is ensured that multiple fixed components can slide smoothly and synchronously in the radial direction, thus guaranteeing the centering and stability of the device when it is fixed.

[0010] In a further technical solution, a first locking bolt is threaded onto the annular body. The first locking bolt can extend into the sliding hole and abut against the sliding rod to lock the position of the sliding rod.

[0011] The design of the first locking bolt allows for quick locking after the hook position is adjusted, effectively preventing deviation caused by accidental sliding of the slide bar during laser device installation or subsequent adjustments, thus ensuring the reliability and stability of the positioning reference.

[0012] In a further technical solution, a connecting block is detachably installed at the end of the slide rod away from the connecting rod. A slot is provided on the connecting block, and the slide rod is inserted into the slot and locked by a second locking bolt.

[0013] The detachable connection between the slide bar and the linkage mechanism is achieved through the connecting block, slot, and second locking bolt, making the assembly, maintenance, and replacement of parts of the device more convenient and flexible.

[0014] In a further technical solution, a gear is rotatably installed inside the cylinder, and several insertion holes are opened on the outer peripheral wall of the cylinder. A rack is fixed on each connecting block, and the rack is inserted into the cylinder through the insertion hole and meshes with the gear.

[0015] Through a gear and rack meshing transmission structure, the remaining hooks can move automatically and synchronously by the same amount when one hook is adjusted. This ensures that the device can always automatically maintain center alignment when adapting to antennas of different apertures, eliminating the tedious step of adjusting each one individually, making operation more efficient and convenient.

[0016] In a further technical solution, the number of racks is three, and the three racks are staggered in the axial direction of the cylinder to avoid mutual interference.

[0017] By distributing the three racks axially in a staggered manner, motion interference between them within the confined space of the cylindrical body is cleverly avoided, ensuring the smooth operation and reliability of the gear and rack transmission system and achieving a compact structure.

[0018] In a further technical solution, the rack has an "L" shaped structure.

[0019] In a further technical solution, the laser lamp is fixed to the cylindrical body via a threaded connection.

[0020] The laser light uses a threaded connection, making installation and disassembly very convenient. This facilitates battery replacement, repair, or replacement with laser lights of different power and type, improving the product's maintainability and usability.

[0021] In a further technical solution, a plurality of fixing rods are fixedly provided on the inner ring of the annulus, the fixing rods are evenly distributed around the circumference, and the fixing rods are fixedly connected to the cylindrical body.

[0022] The ring and cylinder are fixedly connected by a fixing rod, which enhances the structural strength and overall stability of the entire device and ensures the stability and precision of the relative position between the cylinder and the ring, thereby guaranteeing the accuracy of the laser pointing direction.

[0023] In summary, this utility model has the following advantages: the adjustable fixing mechanism can be adapted to various specifications of horn antennas, has a wide range of applications, and is highly versatile;

[0024] The synchronous linkage mechanism enables the adjustment process to be completed in one step, simplifying the operation process, improving installation efficiency, and making operation convenient.

[0025] The coaxial design of the ring reference and laser emission system ensures that the direction indicator is aligned with the antenna axis, resulting in high calibration accuracy and precise positioning.

[0026] Multi-point locking and a robust overall structure ensure the stability of the device during operation, making it less prone to displacement.

[0027] Using visible lasers as a guide makes antenna alignment more intuitive and straightforward, significantly reducing the professional requirements and workload for operators, and improving the efficiency of antenna installation and debugging. Attached Figure Description

[0040] like Figures 1-5 As shown, an auxiliary directional device for a circularly polarized horn antenna includes an auxiliary directional device 200 mounted on a circularly polarized horn antenna 100. The auxiliary directional device 200 includes a ring body 201, which is circular in shape. A cylindrical body 211 is disposed at the axial center of the ring body 201, and the cylindrical body 211 is coaxially disposed with the ring body 201. A plurality of fixing rods 204 evenly distributed in a circular shape are fixedly disposed on the inner ring of the ring body 201. The fixing rods 204 are fixed to the cylindrical body 211. A laser light 214 is fixedly installed. The laser light 214 can be threaded onto the cylindrical body 211. The laser light 214 can emit laser light. Since the annular body 201 is placed at the horn mouth, when placed, the annular body 201 and the horn mouth are coaxially arranged, and the laser light 214 and the horn are also coaxial. This allows the laser light emitted by the laser light 214 to extend outward along the axis of the circularly polarized horn antenna, making it easier for the staff to observe the laser and thus assist in adjusting the orientation of the horn mouth of the circularly polarized horn antenna and adjusting the azimuth of the circularly polarized horn antenna.

[0041] In one embodiment, the annular body 201 is provided with a plurality of sliding holes 207 evenly distributed in a circular shape along the axial direction of the annular body 201. In this embodiment, three sliding holes 207 are provided, which are evenly distributed in a circular shape along the axial direction of the annular body 201, and the extension direction of the sliding holes 207 is: from the outer ring of the annular body 201 to the inner ring of the annular body 201.

[0042] In one embodiment, a slide rod 205 is slidably inserted into each slide hole 207. A connecting rod 203 is fixed to the end of the slide rod 205 away from the cylindrical body 211. The connecting rod 203 is inclined and a hook 202 is fixed to the top of each connecting rod 203. The hook 202 is used to hang on the edge of the horn mouth of the circularly polarized horn antenna. The connecting rod 203 is divergent, specifically diverging from the end near the slide rod 205 to the end where the hook 202 is installed.

[0043] In one embodiment, a first locking bolt 206 is threaded onto the annular body 201. The first locking bolt 206 can extend into the sliding hole 207 and abut against the sliding rod 205 to lock the sliding rod 205 and prevent the sliding rod 205 from sliding.

[0044] In one embodiment, each slide rod 205 is detachably mounted with a connecting block 208 at one end near the cylindrical body 211. Specifically, the connecting block 208 has a slot 209, into which the slide rod 205 is inserted. A second locking bolt 215 is threadedly connected to the connecting block 208. The second locking bolt 215 can extend into the slot 209 and abut against the slide rod 205 to lock the slide rod 205 and the connecting block 208 to prevent separation.

[0045] In one embodiment, a gear 212 is rotatably disposed inside the cylindrical body 211. Several insertion holes 213 are formed on the outer periphery of the cylindrical body 211. Each connecting block 208 is fixed with a rack 210, which is L-shaped. The racks 210 are staggered vertically and slide into the cylindrical body 211 through the insertion holes 213 to mesh with the gear 212. The staggered vertical arrangement avoids mutual interference between the racks 210. (See attached diagram for details.) Figure 5 .

[0046] Specifically, in this embodiment, three connecting blocks 208 are provided. The three connecting blocks 208 are evenly distributed in a circular shape relative to the axis of the cylindrical body 211. Each connecting block 208 is provided with a rack 210, and three racks 210 are also provided. The three racks 210 are staggered vertically in the axial direction of the cylindrical body 211. For example, one rack 210 is fixed to the bottom surface of the connecting block 208, another rack 210 is located in the middle position of the connecting block 208, and the third rack 210 is fixed to the top surface of the connecting block 208, so that the three racks 210 are staggered in the height direction to avoid mutual interference when inserted into the cylindrical body 211 and meshing with the gear 212.

[0047] The specific usage method is as follows:

[0048] Place the auxiliary orientation device 200 at the horn opening of the circularly polarized horn antenna 100, pull the connecting rod 203, the connecting rod 203 drives the sliding rod 205 to move, the sliding rod 205 drives the rack 210 to move, the rack 210 drives the gear 212 to rotate, the gear 212 rotates and drives the other two racks 210 to move simultaneously, thus achieving simultaneous movement of all three racks 210 while maintaining the same amount of movement, thereby adapting to circularly polarized horn antennas 100 with different horn opening sizes. Tighten the first locking bolt 206 to tighten the sliding rod 205 and lock the sliding rod 205. Then, place the hook 202 on the edge of the horn opening of the circularly polarized horn antenna 100, turn on the laser light 214 to emit laser light, thereby providing auxiliary orientation function for subsequent adjustment work.
