Description

Technical Field

[0001] This invention relates to the field of satellite communication technology, and more specifically, to a detachable phased array satellite communication antenna off-axis angle simulation test device. Background Technology

[0002] With the rapid development of low-Earth orbit (LEO) satellite communication technology, the performance requirements for LEO satellite communication terminals are becoming increasingly stringent. In practical applications, antenna equipment typically needs to be tested at different off-axis and azimuth angles. Existing testing equipment often suffers from complex structures, limited adjustment ranges, or inconvenient operation, making it difficult to guarantee testing accuracy and efficiency. Furthermore, some traditional testing devices cannot simulate sufficient angle adjustment ranges, limiting the comprehensiveness and flexibility of the tests. In particular, the disassembly and installation procedures during testing are cumbersome, increasing testing time costs and operational difficulty.

[0003] Therefore, there is an urgent need for a new type of testing device that can not only accurately simulate the working state of the antenna under different off-axis angles and azimuth angles, but also provide convenient disassembly and adjustment functions to adapt to diverse testing needs, thereby improving the testing efficiency and accuracy of low-orbit satellite communication antennas.

[0013] Preferably, a plurality of fixed cylinders are fixedly installed on the top surface of the fixed disk, and a sealing plug is sealed and snapped into the interior of each of the plurality of fixed cylinders. A plurality of external plates are fixedly installed on one side surface of the sector gear.

[0014] Preferably, the bottom surface of the outer plate and the top surface of the sealing plug are both fixedly installed with mounting supports, and a connecting frame is provided between the two mounting supports. The two ends of the connecting frame are respectively rotatably engaged inside the two mounting supports.

[0015] Preferably, an air distribution frame and a transverse plate are provided on the outer side of the fixed plate two. Multiple nozzles are connected to the top surface of the air distribution frame. The air distribution frame is located below the Z-axis adjusting plate and the first cross roller bearing.

[0017] Preferably, a connecting column is fixedly connected to the bottom surface of the transverse plate, and a contact head is fixedly connected to the bottom end of the connecting column, with the outer surface of the contact head contacting the top surface of the irregular frame.

[0018] Preferably, a positioning frame is fixedly installed on one side of the second fixing plate, and a locking block is movably engaged inside the positioning frame. The transverse plate is fixedly installed on one side surface of the locking block.

[0019] The off-axis angle simulation test device for a detachable phased array satellite communication antenna provided by this invention has the following advantages:

[0020] 1. By setting up azimuth angle components, off-axis angle components, and off-column support components, and through the coordinated work of the azimuth angle components and off-axis angle components, combined with crossed roller bearings one and two, a highly efficient, stable, and accurate off-axis angle simulation test scheme is provided for low-Earth orbit satellite communication antennas. This greatly improves testing efficiency and accuracy, meeting the needs of low-Earth orbit satellite communication terminals in multi-angle and multi-directional testing. Furthermore, this device is detachable, allowing for easy assembly or disassembly of individual components as needed, facilitating transportation, storage, and maintenance. Simultaneously, the device's flexible structural design adapts to different operating environments. Whether the antenna equipment is in a horizontal or non-horizontal position, accurate off-axis angle simulation testing can be achieved, ensuring that the antenna equipment is always accurately aligned with the satellite.

[0021] 2. By setting up a self-cleaning component, when the sealing plug moves downward inside the fixed cylinder, it can expel the air inside the fixed cylinder into the delivery pipe through the compression of the sealing plug. Finally, it enters the nozzle through the delivery pipe and is sprayed upward through the air distribution frame, that is, sprayed towards the antenna installed on the top of the Z-axis adjustment plate. This achieves automatic cleaning of the test antenna on the top of the Z-axis adjustment plate, preventing the antenna from being contaminated with dust and affecting the test results.

[0022] 3. By setting up a cleaning adjustment component, when the dual-axis motor rotates, it can also drive the drive gear to rotate. Since the drive gear meshes with the circular gear disc, it can drive the rotating disc to rotate back and forth inside the limit disc. As the rotating disc rotates, the irregular frame rotates synchronously. At this time, when the contact head contacts the different height surfaces of the top of the irregular frame, it can synchronously drive the locking block to move up and down inside the positioning frame, thereby enabling the horizontal plate to move up and down, realizing the adjustment of the height of the air distribution frame, that is, the adjustment of the automatic cleaning height.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Reference Figure 1-8A detachable phased array satellite communication antenna off-axis angle simulation test device is disclosed, comprising an azimuth angle assembly 1, an off-axis angle assembly 2, and an off-axis support assembly 3. The azimuth angle assembly 1 includes a Z-axis adjustment plate 11, a crossed roller bearing 12, and a Z-axis adapter plate 13. The azimuth angle assembly 1 is used for azimuth angle simulation on the horizontal plane of the antenna equipment. The azimuth angle assembly 1 can be circular, square, or other shapes, and contains 360 uniformly distributed 1° mounting holes to support azimuth angle simulation testing of the antenna equipment on the horizontal plane, enabling simulation of a wider range of off-axis angle tests. Through the azimuth angle assembly 1, fine-tuning of the antenna equipment can be achieved, allowing it to rotate horizontally within a precise range.

[0034] The off-axis angle assembly 2 includes a right-angle adapter plate 21, a cross roller bearing 22, and a ball-head locating pin 23. The off-axis angle assembly 2 is used for azimuth angle simulation on the longitudinal plane. The off-axis angle assembly 2 includes 180x1 uniformly distributed mounting holes, is installed on the underside of the azimuth angle assembly 1, and is arranged orthogonally to the azimuth angle assembly 1, so that the antenna device can simulate different off-axis angles within a large angle range.

[0035] The off-pillar support assembly 3 includes a first fixing plate 31, a second fixing plate 32, and an off-pillar support plate 33. There are two sets of the first fixing plate 31 and the second fixing plate 32. The two sets of the first fixing plate 31 and the second fixing plate 32 are symmetrical to each other and connected to each other. The off-pillar support plate 33 is installed on the outer side of each set. The off-pillar support assembly 3 is used for the stable installation of antenna equipment.

[0036] Cross roller bearing 22 is installed inside fixed plate 31. Ball head locating pin 23 is rotatably connected to fixed plate 31 through cross roller bearing 22. Cross roller bearing 12 is installed on the top of right angle adapter plate 21. Z-axis adapter plate 13 is installed inside cross roller bearing 12. Z-axis adjusting plate 11 is rotatably connected to cross roller bearing 12 through Z-axis adapter plate 13.

[0037] In the above description, the azimuth angle component 1 and the off-axis angle component 2 enable the antenna device to be adjusted within the azimuth angle range. The off-axis angle component 2 is located below the azimuth angle component 1 and is orthogonally arranged to the azimuth angle component 1 to conduct off-axis angle simulation tests on the antenna device. The off-axis angle component 2 is installed on both sides of the off-axis support component 3 to ensure the stability of the device and to conduct off-axis angle simulation tests. The Z-axis adjustment plate 11 is connected to the cross roller bearing 12 through the ball head positioning pin 23 to enable precise azimuth angle adjustment of the antenna device. It is connected to the fixing plate 31 through the right angle adapter plate 21. The ball head positioning pin 23 is used for limiting and ensuring that the antenna device is stably adjusted within the off-axis angle range.

[0038] During operation, azimuth component 1 is installed above off-axis component 2, and the precise connection between the two is ensured by cross roller bearing 22. Next, off-axis component 2 is installed on off-axis support component 3, providing a stable foundation for the antenna equipment. The satellite communication antenna to be tested is then installed on azimuth component 1, and its mounting holes ensure a secure fixation. According to the antenna's installation requirements, the corresponding components are adjusted to ensure it approaches the required initial off-axis angle. By adjusting azimuth component 1, the azimuth angle of the antenna equipment can be precisely fine-tuned. The design of the azimuth component allows for precise horizontal adjustment of the antenna, ensuring it points in the correct direction. Using the adjustment function of off-axis component 2, the tilt angle of the antenna is adjusted to simulate different off-axis angles. The cross roller bearing 22 is used to adapt to different off-axis angle testing requirements. Throughout the adjustment process, off-axis support component 3 provides stable support, preventing equipment swaying or displacement, ensuring the stability and accuracy of the antenna equipment during adjustment. After completing the azimuth and off-axis angle adjustments, simulation testing can begin. Depending on the testing requirements, the device can simulate different antenna angles to test the performance of the equipment at various angles, ensuring that it can accurately align with the satellite. After the test is completed, each component can be disassembled as needed to facilitate the transportation, storage and maintenance of the equipment.

[0039] A fixing plate 4 is installed on the outside of the column support assembly 3, and a self-cleaning assembly 5 and a cleaning adjustment assembly 6 are provided on the top of the fixing plate 4.

[0040] The self-cleaning component 5 includes a mounting bracket 51. A drive shaft 52 is rotatably mounted inside the mounting bracket 51. A bevel gear 53 is fixedly connected to the top of the drive shaft 52. A rotating shaft 54 ​​is rotatably mounted inside a fixing plate 31. Both ends of the rotating shaft 54 ​​extend to the outside of the fixing plate 31. A sector gear 56 is fixedly sleeved on the outer surface of the rotating shaft 54 ​​extending to the outside of the fixing plate 31. A bevel gear 55 is fixedly mounted at one end of the bevel gear 53 located on the outside of the fixing plate 31. The bevel gear 55 meshes with the bevel gear 53. A dual-axis motor 59 is fixedly mounted inside the mounting bracket 51. One output end of the dual-axis motor 59 is fixedly connected to the drive shaft 52. Multiple fixing cylinders 510 are fixedly mounted on the top surface of the fixing plate 4. Each fixing cylinder 510 has a sealing plug 518 sealed inside. Multiple external plates 58 are fixedly mounted on one side surface of the sector gear 56. The position of the connecting plate 58 corresponds to the position of multiple fixed cylinders 510. The bottom surface of the outer connecting plate 58 and the top surface of the sealing plug 518 are both fixedly installed with mounting supports 519. A connecting frame 520 is provided between the two mounting supports 519. The two ends of the connecting frame 520 are respectively rotatably snapped into the inside of the two mounting supports 519. The outer side of the second fixed plate 32 is provided with a wind distribution frame 512 and a transverse plate 511. Multiple nozzles 513 are connected to the top surface of the wind distribution frame 512. The wind distribution frame 512 is located below the Z-axis adjusting plate 11 and the first cross roller bearing 12. A conveying pipe 514 is fixedly connected between the wind distribution frame 512 and the fixed cylinder 510. A one-way valve 515 is installed on the outside of the conveying pipe 514. An air inlet pipe 516 is fixedly connected to the outer surface of the fixed cylinder 510. A one-way valve 517 is installed on the outer surface of the air inlet pipe 516. The flow direction between the one-way valve 517 and the one-way valve 515 is opposite.

[0041] A sector-shaped gear 57 is fixedly installed on the arc surface of the right-angle adapter plate 21, and the sector-shaped gear 57 meshes with the sector gear 56.

[0042] During operation, when testing the antenna, specifically during off-axis testing, the dual-axis motor 59 is started. The motor 59 drives the transmission shaft 52 to rotate, which in turn drives the bevel gear 55. Since the bevel gear 55 meshes with the sector gear 56, the sector gear 56, through its transmission with the sector gear disk 57, causes the right-angle adapter plate 21 to move off-axis. This allows for off-axis testing of the antenna mounted on the top of the Z-axis adjustment plate 11. Furthermore, during the test, the rotation of the sector gear 56, under the action of the connecting frame 520, causes the sealing plug 518 to move inside the fixed cylinder 510. When the sealing plate 518 moves downward inside the fixed cylinder 510, it can squeeze the air inside the fixed cylinder 510 into the delivery pipe 514 through the sealing plate 518. Finally, it enters the nozzle 513 through the delivery pipe 514 and is sprayed upward through the air distribution frame 512, that is, sprayed towards the antenna installed on the top of the Z-axis adjustment plate 11. This realizes the automatic cleaning of the test antenna on the top of the Z-axis adjustment plate 11, preventing the problem of dust on the outside of the antenna from affecting the test effect. When the sealing plate 518 moves upward inside the fixed cylinder 510, it can draw fresh air back into the fixed cylinder 510 through the air inlet pipe 516, completing the cycle.

[0043] Furthermore, through the arrangement of multiple fixed cylinders 510 in the above process, when the sector gear 56 rotates back and forth, the sealing plugs 518 inside the two adjacent fixed cylinders 510 can move in opposite directions. That is, when one fixed cylinder 510 discharges air outward, the other is in the state of suction, which can ensure the continuity of automatic cleaning.

[0044] The cleaning and adjustment assembly 6 includes a limiting plate 61, which is fixedly installed on the top surface of the fixed plate 4. A rotating plate 62 is rotatably engaged inside the limiting plate 61. A shaped frame 63 is fixedly installed on the top of the rotating plate 62. A circular gear plate 64 is fixedly installed on the inner wall of the rotating plate 62. A drive gear 65 is fixedly connected to the other output end of the dual-axis motor 59. The drive gear 65 and the circular gear plate 64 mesh with each other. A connecting post 68 is fixedly connected to the bottom surface of the transverse plate 511. A contact head 69 is fixedly connected to the bottom end of the connecting post 68. The outer surface of the contact head 69 contacts the top surface of the shaped frame 63. A positioning frame 66 is fixedly installed on one side of the fixed plate 32. A locking block 67 is movably engaged inside the positioning frame 66. The transverse plate 511 is fixedly installed on one side surface of the locking block 67.

[0045] During operation, as the dual-axis motor 59 rotates, it also drives the drive gear 65 to rotate. Since the drive gear 65 meshes with the circular gear disc 64, it drives the rotating disc 62 to rotate back and forth inside the limiting disc 61. As the rotating disc 62 rotates, the irregular frame 63 rotates synchronously. At this time, when the contact head 69 contacts the different height surfaces of the top of the irregular frame 63, it can synchronously drive the locking block 67 to move up and down inside the positioning frame 66, thereby enabling the horizontal plate 511 to move up and down, realizing the adjustment of the height of the air distribution frame 512, which means that the automatic cleaning height can be adjusted.

[0046] During this process, when the height of the air distribution frame 512 is too low, that is, when the angle of the Z-axis adjustment plate 11 is too large, the height of the air distribution frame 512 can be adjusted adaptively according to the angle of the Z-axis adjustment plate 11.

[0047] Operating Procedure: During operation, azimuth component 1 is installed above off-axis component 2, and a precise connection between the two is ensured by cross roller bearing 22. Next, off-axis component 2 is installed on off-axis support component 3, providing a stable foundation for the antenna equipment. The satellite communication antenna to be tested is then installed on azimuth component 1, and its mounting holes ensure a secure fixation. According to the antenna's installation requirements, the corresponding components are adjusted to ensure it approaches the required initial off-axis angle. By adjusting azimuth component 1, the azimuth angle of the antenna equipment can be precisely fine-tuned. The design of the azimuth component allows for precise horizontal adjustment of the antenna, ensuring it points in the correct direction. Using the adjustment function of off-axis component 2, the tilt angle of the antenna is adjusted to simulate different off-axis angles. The cross roller bearing 22 is used to adapt to different off-axis angle testing requirements. Throughout the adjustment process, off-axis support component 3 provides stable support, preventing equipment swaying or displacement, ensuring the stability and accuracy of the antenna equipment during adjustment. After completing the azimuth and off-axis angle adjustments, simulation testing can begin. Depending on the testing requirements, the device can simulate different antenna angles to test the performance of the equipment at various angles, ensuring that it can accurately align with the satellite. After the test is completed, each component can be disassembled as needed to facilitate the transportation, storage and maintenance of the equipment.

[0048] By controlling the start of the dual-axis motor 59, the transmission shaft 52 rotates during startup, which in turn drives the bevel gear 55 to rotate. Since the bevel gear 55 meshes with the sector gear 56, the sector gear 56, through its transmission with the sector disk 57, drives the right-angle adapter plate 21 to move away from its angle. This allows for angle testing of the antenna mounted on the top of the Z-axis adjustment plate 11. During the test, the rotation of the sector gear 56 causes the sealing disc 518 to move up and down inside the fixed cylinder 510 under the action of the connecting frame 520. When the sealing disc 518 moves downward inside the fixed cylinder 510, it compresses the air inside the fixed cylinder 510 and discharges it into the delivery pipe 514, which then enters the nozzle 513 through the delivery pipe 514. Furthermore, the air is sprayed upwards through the air distribution frame 512, that is, towards the antenna mounted on the top of the Z-axis adjustment plate 11, thereby achieving automatic cleaning of the test antenna on the top of the Z-axis adjustment plate 11 and preventing dust from contaminating the antenna and affecting the test results. When the dual-axis motor 59 rotates, it can also drive the drive gear 65 to rotate. Since the drive gear 65 meshes with the circular gear disk 64, it can drive the rotating disk 62 to rotate back and forth inside the limiting disk 61. As the rotating disk 62 rotates, the irregular frame 63 rotates synchronously. At this time, when the contact head 69 contacts the different height surfaces on the top of the irregular frame 63, it can synchronously drive the locking block 67 to move up and down inside the positioning frame 66, thereby enabling the horizontal plate 511 to move up and down, realizing the adjustment of the height of the air distribution frame 512, that is, realizing the adjustment of the automatic cleaning height.
