Description

Technical Field

[0001] This utility model relates to the field of satellite downconverter technology, specifically a general-purpose multi-output low-noise satellite downconverter. Background Technology

[0002] A downconverter reduces the frequency of satellite signals from the feedhorn and amplifies the signal before transmitting it to the satellite receiver. Because satellite signals are already quite weak before reaching the antenna, and the higher the frequency of coaxial cable transmission, the greater the signal loss, an INB is needed to improve this. The INB's working process is to first amplify the high-frequency satellite signal by hundreds of thousands of times, and then use a local oscillator circuit to convert the high-frequency signal to an intermediate frequency of 950MHz-2050MHz (the intermediate frequency range depends on the type of INB) to facilitate coaxial cable transmission and demodulation and operation of the satellite receiver.

[0003] For example, Chinese patent CN219367299U discloses a universal multi-output low-noise satellite LNB downconverter, which includes a downconverter body, a downconverter connecting support, and a downconverter fixing base. The downconverter body is connected to the top of the downconverter connecting support, and the downconverter connecting support is connected to the inner top side of the downconverter fixing base. The downconverter body can rotate on the top vertical plane of the downconverter connecting support, and the downconverter connecting support can rotate and be adjusted up and down on the inner side of the downconverter fixing base.

[0004] The aforementioned general-purpose multi-output low-noise satellite LNB downconverter still has certain shortcomings. While it has a stable fixing effect and flexible adjustment characteristics through all-round adjustment, the angle adjustment requires manual adjustment, making the adjustment method not very automatic. Therefore, this application proposes a general-purpose multi-output low-noise satellite downconverter to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a universal multi-output low-noise satellite frequency reducer, which has advantages such as easy angle adjustment and improved stability, and solves the problem of low automation in the adjustment method.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a universal multi-output low-noise satellite frequency reducer, comprising a platform, an adjustment mechanism above the platform, a satellite frequency reducer body above the platform, multiple external output interfaces on the outer side of the satellite frequency reducer body, a rotation mechanism below the platform, a base below the platform, and a lifting device above the base.

[0007] Furthermore, the adjustment mechanism includes a movable block hinged to the upper surface of the platform via a hinge shaft, an electric push rod is provided on the side of the movable block away from the platform, a hinge column is provided on the outer side of the output shaft of the electric push rod, and a coupling is provided between the platform and the main body of the satellite downconverter.

[0008] Furthermore, the adjustment mechanism also includes a protective box located on the side of the movable block away from the platform, and the electric push rod is located inside the protective box.

[0009] Furthermore, the end of the hinge column away from the electric push rod is hinged to the bottom of the satellite downconverter body via a hinge shaft.

[0010] Furthermore, the rotating mechanism includes an annular sleeve fixed to the lower surface of the platform by bolts. An internal gear ring is provided on the inner side of the inner cavity of the annular sleeve, and a gear meshes on the inner side of the internal gear ring. A connecting cylinder is rotatably connected to the bottom of the platform through a bearing, and a motor is provided inside the connecting cylinder.

[0011] Furthermore, the connecting cylinder is welded to the outside of the output shaft of the lifting device, and a groove extending to the inside of the front side of the connecting cylinder is provided, with the motor located in the groove.

[0012] Furthermore, the gear is welded to the outside of the motor output shaft, and a slot extending into the inner cavity is provided on the left side of the connecting cylinder, with the gear located in the slot.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This universal multi-output low-noise satellite downconverter features a lifting device that allows for height adjustment of the downconverter body. Simultaneously, starting the motor causes the gears to rotate the internal gear ring, which in turn rotates the ring sleeve, causing the platform to rotate and thus the downconverter body itself. When the angle of the downconverter body needs adjustment, simply activating the electric push rod allows the output shaft to adjust the angle, enhancing practicality and eliminating the need for manual adjustment.

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.

[0020] Please see Figure 1 This embodiment of a general-purpose multi-output low-noise satellite downconverter includes a platform 1, an adjustment mechanism 2 above the platform 1, a satellite downconverter body 3 above the platform 1, multiple external output interfaces 5 on the outside of the satellite downconverter body 3, a rotation mechanism 4 below the platform 1, a base 6 below the platform 1, and a lifting device 7 above the base 6.

[0021] The lifting device 7 is a conventional cylinder or other device in the prior art, which is well known to those skilled in the art, and will not be described in detail here.

[0022] Understandably, the height of the satellite downconverter body 3 can be adjusted by the lifting device 7, and the general-purpose multi-output low-noise satellite downconverter is fixed to the area to be installed by bolts through its base 6.

[0023] Please see Figure 2 In this embodiment, the adjustment mechanism 2 includes a movable block 201 hinged to the upper surface of the platform 1 via a hinge shaft. An electric push rod 202 is provided on the side of the movable block 201 away from the platform 1. A hinge column 203 is provided on the outer side of the output shaft of the electric push rod 202. A coupling 205 is provided between the platform 1 and the satellite downconverter body 3. The coupling 205 is fixedly provided between the platform 1 and the satellite downconverter body 3.

[0024] The adjustment mechanism 2 also includes a protective box 204 located on the side of the movable block 201 away from the platform 1. The electric push rod 202 is located inside the protective box 204. The end of the hinge column 203 away from the electric push rod 202 is hinged to the bottom of the satellite downconverter body 3 through the hinge shaft.

[0025] Understandably, when it is necessary to adjust the angle of the satellite downconverter body 3, simply activate the electric push rod 202, and the output shaft of the electric push rod 202 can drive the satellite downconverter body 3 to adjust the angle, improving practicality and eliminating the need for manual adjustment.

[0026] Please see Figure 3 In this embodiment, the rotating mechanism 4 includes an annular sleeve 401 fixed to the lower surface of the platform 1 by bolts. An internal gear ring 402 is provided on the inner side of the inner cavity of the annular sleeve 401. A gear 403 meshes on the inner side of the internal gear ring 402. A connecting cylinder 404 is rotatably connected to the bottom of the platform 1 through a bearing. A motor 405 is provided inside the connecting cylinder 404.

[0027] The connecting cylinder 404 is welded to the outside of the output shaft of the lifting device 7. A groove extending to the inside of the front side of the connecting cylinder 404 is provided. The motor 405 is located in the groove. The gear 403 is welded to the outside of the output shaft of the motor 405. A slot extending to the inner cavity of the connecting cylinder 404 is provided on the left side. When the motor 405 is started, the gear 403 drives the internal gear ring 402 to rotate, thereby driving the ring sleeve 401 to rotate, which in turn causes the platform 1 to start rotating, causing the satellite frequency reducer body 3 to rotate. The gear 403 is located in the slot.

[0028] It is understood that the satellite downconverter body 3 in this application and the downconverter body in the Chinese patent (CN219367299U) are both conventional general-purpose multi-output low-noise satellite downconverters in the prior art. This application will not elaborate on their working principle and model.

[0029] The height of the satellite frequency reducer body 3 can be adjusted by the lifting device 7. At the same time, starting the motor 405 will cause the gear 403 to drive the internal gear ring 402 to rotate, thereby driving the ring sleeve 401 to rotate, which in turn causes the platform 1 to rotate, making the satellite frequency reducer body 3 rotate. When it is necessary to adjust the angle of the satellite frequency reducer body 3, simply start the electric push rod 202, and the output shaft of the electric push rod 202 will drive the satellite frequency reducer body 3 to adjust the angle, improving practicality and eliminating the need for manual adjustment.
