Description

Technical Field

[0001] This invention relates to the field of satellite antenna technology, and in particular to an antenna support with an elevation structure. Background Technology

[0002] An antenna is a device that converts electrical signals into electromagnetic waves and vice versa. Its core function is to transmit or receive radio waves, thereby enabling long-distance wireless communication, broadcasting, direction finding, and detection. It is widely used in many fields such as communications, broadcasting, radar, satellite navigation, radio astronomy, and the Internet of Things. An antenna support is a mechanical structure used to fix, support, and adjust the spatial position and orientation of the antenna. It ensures that the antenna is stably erected at a high or specific location to obtain the best signal, while resisting environmental influences such as wind loads. It is an indispensable physical foundation for antenna systems.

[0003] When existing antenna brackets with elevation structures are exposed to the external environment for a long time, their elevation adjustment mechanism may fail or wear due to environmental factors or excessive elevation adjustments, causing the elevation axis to loosen. This can lead to the antenna body rotating under its own weight, eventually contacting the ground and being damaged, reducing work efficiency and increasing maintenance costs. Summary of the Invention

[0017] 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.

[0018] The antenna bracket with an elevation structure disclosed in this invention is mainly used in scenarios where the elevation mechanism of the antenna bracket is prone to wear and failure after long-term exposure or frequent adjustment, resulting in the antenna falling and being damaged due to its own weight, thereby reducing work efficiency and increasing maintenance costs.

[0019] Reference Figures 1-5 An antenna support with an elevation structure includes a base 9. Two elevation supports 3 are fixedly connected at equal intervals on the upper side of the base 9. A common elevation shaft 5 is connected to opposite sides of the elevation supports 3 via bearings. The elevation shaft 5 has a hollow interior and a rough inner wall. Elevation ratchet wheels 10 are fixedly connected to the outer walls of both ends of the elevation shaft 5. Monitoring components 8 are respectively installed on the sides of the two elevation supports 3 that are far apart from each other. A common weightlessness protection emergency component 7 is installed on both elevation supports 3. The weightlessness protection emergency component 7 includes a protective groove 706. The cylinder 706 is located inside the pitch axis 5. The outer wall of the protective groove cylinder 706 is provided with multiple long grooves. Multiple brake plates 709 are connected at equal intervals inside the multiple long grooves through bearings. Brake blocks 711 are connected to the openings at one end of the multiple brake plates 709 through bearings. The multiple brake blocks 711 are pressed and contacted with the inner wall of the pitch axis 5. One end of a brake torsion spring 712 is fixedly connected to both sides of the lower end of the multiple brake blocks 711. The other ends of the two brake torsion springs 712 located on the same brake block 711 are fixedly connected to the inner wall of the opening at one end of the corresponding brake plate 709.

[0020] In this invention, a lead screw 708 is connected to the inside of the protective groove cylinder 706 via a bearing. Multiple sliding groove plates 710 are equally spaced on the outer wall of the lead screw 708. Multiple rotating grooves are equally spaced on the outer wall of the multiple sliding groove plates 710. Limiting sleeve plates 714 are connected to the inside of the multiple rotating grooves via bearings. One end of multiple brake plates 709 away from the brake block 711 is slidably connected to the inside of the corresponding limiting sleeve plate 714. One end of two telescopic springs 713 are fixedly connected to the outer wall of the end of the multiple brake plates 709 close to the corresponding limiting sleeve plate 714. The other ends of the two telescopic springs 713 located on the same brake plate 709 are fixedly connected to the inner wall of the corresponding limiting sleeve plate 714.

[0021] In this invention, a brake motor 707 is fixedly connected to one end of the protective groove cylinder 706, and the driving end of the brake motor 707 is connected to one end of the lead screw 708 through a coupling. A driven ratchet 705 is fixedly connected to the outer wall of the end of the protective groove cylinder 706 away from the brake motor 707.

[0022] In this invention, two pitch supports 3 are fixedly connected to L-shaped fixing plates 701 on opposite sides. Protective holes are opened on opposite sides of the two L-shaped fixing plates 701. The two ends of the protective groove cylinder 706 are connected to the corresponding protective holes through bearings. The outer wall of one of the L-shaped fixing plates 701 is connected to the drive shaft 704 through a bearing.

[0023] In this invention, an active ratchet 702 is fixedly connected to the outer wall of the active shaft 704, and the active ratchet 702 meshes with the driven ratchet 705. An emergency motor 703 is fixedly connected to the outer wall of one of the L-shaped fixing plates 701, and the drive end of the emergency motor 703 is connected to one end of the active shaft 704 through a coupling.

[0024] Specifically, when the antenna body 6 is detected to be rotating due to weightlessness, the brake motor 707 drives the lead screw 708 to rotate, thereby moving multiple sliding slot plates 710. During this process, as the sliding slot plates 710 move, multiple brake plates 709 rotate, causing the corresponding brake blocks 711 to quickly press against the inner wall of the pitch axis 5. This stops the pitch axis 5 through friction. The emergency motor 703 drives the drive shaft 704 to rotate the drive ratchet 702, which in turn drives the driven ratchet 705 to rotate the protective slot cylinder 706. Under the action of friction, the emergency motor 703 can drive the pitch axis 5 to rotate, thereby performing emergency pitch adjustment of the antenna body 6.

[0025] In specific application scenarios, the elevation axis 5 is braked by friction to prevent the antenna body 6 from continuing to rotate under weightlessness, thus ensuring that the antenna body 6 will not collide with the ground and cause damage, reducing maintenance costs. The sliding and telescopic nature of one end of multiple braking plates 709 inside the corresponding limiting sleeve 714, as well as the action of multiple telescopic springs 713, ensures that the braking plates 709 will not jam during rotation. At the same time, the action of multiple braking torsion springs 712 can make multiple braking blocks 711 stably contact the inner wall of the elevation axis 5, thereby improving braking efficiency. The emergency motor 703 drives the drive shaft 704 to rotate the drive ratchet 702, which in turn drives the driven ratchet 705 to rotate the protective groove cylinder 706. Under the action of friction, the emergency motor 703 can drive the elevation axis 5 to rotate, thereby performing emergency elevation adjustment of the antenna body 6, ensuring continuous operation and greatly improving work efficiency.

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 In a preferred embodiment, the monitoring component 8 includes an alarm 802. Two alarms 802 are respectively disposed on opposite sides of the corresponding pitch supports 3. A crescent-shaped plate 801 is fixedly connected to the opposite sides of the two pitch supports 3. A sliding groove ring 809 is fixedly connected to the upper inner wall of the crescent-shaped plate 801. A cross plate 810 is fixedly connected to one side of the sliding groove ring 809.

[0027] In this invention, a through hole is provided on one side of the cross plate 810, and a rotating shaft 811 is connected to the inside of the through hole through a bearing. A driven plate 806 is fixedly connected to one end of the rotating shaft 811, and a monitoring torsion spring 807 is sleeved on the outer wall of the rotating shaft 811. One end of the monitoring torsion spring 807 is fixedly connected to the driven plate 806, and the other end is fixedly connected to the cross plate 810. One end of the driven plate 806 slides inside the sliding groove ring 809, and a pressure sensor 808 is provided on the inner wall of one end of the driven plate 806.

[0028] In this invention, the two pitch supports 3 are respectively connected to the monitoring shafts 804 by bearings on the sides that are far apart from each other. The lower outer walls of the two monitoring shafts 804 are respectively fixedly connected to monitoring ratchet 803. The two monitoring ratchet 803 are respectively engaged with the corresponding pitch ratchet 10. The upper outer walls of the two monitoring shafts 804 are respectively fixedly connected to actuating plates 805. The two actuating plates 805 are respectively pressed and contacted with the force-receiving end of the corresponding pressure sensor 808.

[0029] Specifically, when the regulating cylinder 1 fails, causing the antenna body 6 to rotate in a state of weightlessness, at that instant, the pitch axis 5 rotates, causing the two pitch ratchet wheels 10 to drive the monitoring ratchet wheel 803 to rotate the monitoring shaft 804. During this process, the actuating plate 805 located on the monitoring shaft 804 presses the pressure sensor 808 with a rapid and huge force, causing the driven plate 806 equipped with the pressure sensor 808 to overcome the monitoring torsion spring 807 and rotate a distance. At the same time, after the pressure sensor 808 receives a pressure exceeding the threshold, it triggers the alarm 802 to prove that the antenna body 6 has fallen off due to weightlessness and to notify the staff to come for repair.

[0030] In specific application scenarios, by monitoring the function of the torsion spring 807, the pressure sensor 808 on the driven plate 806 is always in close contact with the actuating plate 805, thereby ensuring that the moment when the antenna body 6 undergoes weightlessness and rotation is accurately detected, which facilitates subsequent protection and emergency work while improving maintenance efficiency.

[0031] Reference Figure 1 and Figure 2 In a preferred embodiment, an adjusting cylinder 1 is provided on the upper side of the base 9. The telescopic end of the adjusting cylinder 1 is fixedly connected to the base 2. One end of the adjusting lever 4 is provided inside the base 2. The other end of the adjusting lever 4 is fixedly connected to the outer wall of the pitch axis 5. The outer wall of the pitch axis 5 is provided with the antenna body 6.

[0032] Working principle: During use, the base 2 can be moved up and down by controlling the extension and retraction of the adjusting cylinder 1. At the same time, since the two ends of the adjusting lever 4 are connected to the base 2 and the pitch axis 5 respectively, the pitch axis 5 can rotate within the range of movement under the extension and retraction of the adjusting cylinder 1. Finally, the antenna body 6 on the pitch axis 5 can perform pitch adjustment. Since the adjusting lever 4 and the base 2 are connected by a limit sliding connection, the base 2 can avoid jamming when controlling the rotation of the adjusting lever 4. When the regulating cylinder 1 fails, causing the antenna body 6 to rotate in a state of weightlessness, at that instant, the pitch axis 5 rotates, causing the two pitch ratchet wheels 10 to drive the monitoring ratchet wheel 803 to rotate the monitoring shaft 804. During this process, the actuating plate 805 on the monitoring shaft 804 presses the pressure sensor 808 with a rapid and huge force, causing the driven plate 806, which is equipped with the pressure sensor 808, to overcome the rotational movement of the monitoring torsion spring 807. At the same time, after the pressure sensor 808 receives a pressure exceeding the threshold, it triggers the alarm 802 to prove that the antenna body 6 has fallen off due to weightlessness and to notify the staff to come for repair. The monitoring torsion spring 807 ensures that the pressure sensor 808 on the driven plate 806 is always in close contact with the actuating plate 805, thereby ensuring that the instant that the antenna body 6 rotates in a state of weightlessness is accurately detected, which facilitates subsequent protection and emergency work and improves maintenance efficiency. When the monitoring component 8 detects that the antenna body 6 is rotating under weightlessness, the braking motor 707 drives the lead screw 708 to rotate, thereby moving multiple sliding slot plates 710. During this process, as the sliding slot plates 710 move, multiple braking plates 709 rotate, causing the corresponding braking blocks 711 to quickly press against the inner wall of the pitch axis 5. This stops the pitch axis 5 through friction, preventing the antenna body 6 from continuing to rotate under weightlessness. This ensures that the antenna body 6 will not collide with the ground and cause damage, reducing maintenance costs. The multiple braking plates 709 are retractable by sliding within the corresponding limiting sleeves 714 at one end. The multiple extension springs 713 ensure that the brake plate 709 will not jam during rotation. At the same time, the multiple brake torsion springs 712 ensure that the multiple brake blocks 711 are stably in contact with the inner wall of the pitch axis 5, thereby improving braking efficiency. After braking the pitch axis 5, the emergency motor 703 drives the drive shaft 704 to rotate the drive ratchet 702, which in turn drives the driven ratchet 705 to rotate the protective groove cylinder 706. Under the action of friction, the emergency motor 703 drives the pitch axis 5 to rotate, thereby performing emergency pitch adjustment of the antenna body 6, ensuring continuous operation and greatly improving work efficiency.
