An elevation adjustment device for satellite radar

Abstract

This utility model discloses an elevation angle adjustment device for satellite radar, belonging to the field of radar technology. It includes a fixed base with a fixing hole on one side. A support bar is connected above the fixed base, and a mounting plate is slidably mounted on the support bar. A connecting groove is formed on the mounting plate, and a fixing rod is connected above the mounting plate. A hollow column is connected to one side of the mounting plate, and a motor is fixedly mounted at one end of the hollow column. This elevation angle adjustment device for satellite radar, by starting the motor to rotate the threaded rod, causes a threaded sleeve that is threadedly engaged with the threaded rod to slide inside the hollow column. This causes the threaded sleeve to pass through the mounting plate and push a slider through the connecting sleeve, causing the slider to slide on a guide plate. Furthermore, due to the elongation of the threaded sleeve and the hollow column, a movable platform can simultaneously rotate around the fixing rod, thereby adjusting the angle of the movable platform and changing the elevation angle of the radar body. No manual climbing is required, making operation convenient.

Description

Technical Field

[0001] This utility model belongs to the field of radar technology, specifically an elevation angle adjustment device for satellite radar. Background Technology

[0002] Radar is an electronic system that uses radio waves to detect, locate, and track targets. Its basic principle is to emit electromagnetic waves and receive the echoes reflected by the target. By analyzing information such as the time delay and frequency changes of the echoes, parameters such as the target's distance, speed, azimuth, and altitude can be determined. Radar technology is widely used in military, civil aviation, meteorology, navigation, and autonomous driving fields.

[0003] Before use, radar needs to be adjusted to a suitable working elevation angle, and usually the elevation angle needs to be readjusted after a period of use. However, since radar antennas are usually set up high on buildings, it is time-consuming, laborious and dangerous for people to climb up to adjust them. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides an elevation angle adjustment device for satellite radar, which solves the problem that since radar antennas are generally installed at high places on buildings, it is time-consuming, laborious, and also dangerous for people to climb up to adjust them.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an elevation angle adjustment device for satellite radar, including a fixed base, a fixing hole on one side of the fixed base, a support bar connected above the fixed base, an mounting plate slidably mounted on the support bar, a connecting groove on the mounting plate, a fixing rod connected above the mounting plate, a hollow column connected to one side of the mounting plate, and a motor fixedly mounted at one end of the hollow column;

[0006] The motor output shaft is connected to a threaded rod, and a threaded sleeve is installed on the threaded rod. A connecting sleeve is connected to one end of the threaded sleeve. A movable platform is rotatably installed on the fixed rod. A connecting hole is opened on the movable platform. The radar body is fixedly installed on the movable platform. A guide plate is connected to one side of the movable platform, and a slider is slidably connected to the guide plate.

[0007] As a further embodiment of this utility model: a threaded hole is provided on one side of the support bar, and a threaded hole is provided on the mounting plate. The threaded hole and the threaded hole are positioned correspondingly and are connected by a bolt through a common thread.

[0008] As a further embodiment of this utility model: a guide groove is provided on the slider, a connecting rod is connected to the slider, the slider is slidably connected to the guide plate through the guide groove, and both the guide plate and the guide groove are T-shaped designs.

[0009] As a further embodiment of this utility model: the threaded rod is rotatably connected to the hollow column through a bearing, and the threaded sleeve slides inside the hollow column with one end penetrating through the mounting plate.

[0010] As a further embodiment of this utility model: the connecting sleeve is rotatably connected to the connecting rod, and the fixing rod is rotatably engaged with the connecting hole through a bearing.

[0011] As a further embodiment of this utility model: the support bar is inserted into the connecting groove, and the fixing seat has a fixing bar hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This satellite radar uses an elevation adjustment device consisting of a movable platform, a hollow column, a motor, a threaded rod, a threaded sleeve, a slider, and a guide plate. When adjustment is needed, the operator starts the motor to rotate the threaded rod, causing the threaded sleeve, which is threaded to engage with the threaded rod, to slide inside the hollow column. This causes the threaded sleeve to travel across the mounting plate and push the slider through the connecting sleeve, causing the slider to slide on the guide plate. Furthermore, due to the elongation of the overall length of the threaded sleeve and the hollow column, the movable platform can simultaneously rotate around the fixed rod, thereby adjusting the angle of the movable platform and changing the elevation angle of the radar body. This eliminates the need for manual climbing and is easy to operate.

[0014] 2. The elevation adjustment device for this satellite radar uses a support bar, a connecting groove, and threaded holes one and two. After the mounting base is fixed, the operator inserts the support bar into the connecting groove so that the mounting plate can be combined with the support bar. At this time, threaded holes one and two will be aligned with each other, making it easy for the operator to screw in the bolts for fixing, thus completing the assembly and fixing. The operation is simple and convenient, improving the efficiency of disassembly and assembly, and thus facilitating maintenance. Attached Figure Description

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-4 As shown, this utility model provides a technical solution: an elevation angle adjustment device for satellite radar, including a fixed base 1, a fixed hole 2 on one side of the fixed base 1, a support bar 3 connected above the fixed base 1, a threaded hole 17 on one side of the support bar 3, and a threaded hole 18 on the mounting plate 4. The threaded hole 17 and the threaded hole 18 are corresponding in position and are connected to a bolt by a common thread. When the support bar 3 is fully inserted into the connecting groove 5, the threaded hole 17 and the threaded hole 18 will automatically align, thereby facilitating the operator to screw in the bolt for fixation.

[0022] A mounting plate 4 is slidably mounted on the support bar 3. A connecting groove 5 is provided on the mounting plate 4. The support bar 3 and the connecting groove 5 are inserted into each other. A fixing bar hole 21 is provided on the fixing seat 1. The fixing seat 1 can be fixed by screwing bolts into the fixing hole 2 and the fixing bar hole 21 to prevent accidental sliding during operation. The design of the fixing bar hole 21 allows the position of the fixing seat 1 to be adjusted within a certain range for easy installation and positioning. The insertion of the support bar 3 and the connecting groove 5 makes it easy for the operator to quickly position and fix the mounting plate 4 on the fixing seat 1.

[0023] A fixed rod 6 is connected above the mounting plate 4, and a hollow column 7 is connected to one side of the mounting plate 4. A motor 8 is fixedly installed at one end of the hollow column 7. The output shaft of the motor 8 is connected to a threaded rod 9. The threaded rod 9 is rotatably connected to the hollow column 7 through a bearing. A threaded sleeve 10 slides inside the hollow column 7 and one end passes through the mounting plate 4. Through the threaded engagement between the threaded sleeve 10 and the threaded rod 9, the threaded sleeve 10 can pass through the mounting plate 4 and push the slider 16 to move when the threaded rod 9 rotates, thereby changing the angle of the movable platform 12 and the radar body 14 without manual adjustment, thus improving efficiency.

[0024] A threaded sleeve 10 is threadedly fitted onto the threaded rod 9. One end of the threaded sleeve 10 is connected to a connecting sleeve 11. The connecting sleeve 11 is rotatably connected to the connecting rod 20. The fixed rod 6 is rotatably fitted to the connecting hole 13 through a bearing. The rotatable fit between the connecting sleeve 11 and the connecting rod 20 causes the included angle between the slider 16 and the threaded sleeve 10 to change synchronously when the movable table 12 rotates, thereby facilitating the movement of the slider 16 by the threaded sleeve 10.

[0025] A movable platform 12 is rotatably mounted on the fixed rod 6. A connecting hole 13 is provided on the movable platform 12. The radar body 14 is fixedly mounted on the movable platform 12. A guide plate 15 is connected to one side of the movable platform 12. A slider 16 is slidably connected to the guide plate 15. A guide groove 19 is provided on the slider 16. A connecting rod 20 is connected to the slider 16. The slider 16 is slidably connected to the guide plate 15 through the guide groove 19. Both the guide plate 15 and the guide groove 19 are T-shaped. The T-shaped design of the guide plate 15 can restrict the slider 16 and prevent the slider 16 from falling off or deviating, so that the slider 16 can move smoothly.

[0026] The working principle of this utility model is as follows:

[0027] After fixing the base 1, the support bar 3 is inserted into the connecting groove 5, causing the mounting plate 4 and the support bar 3 to be combined. At this time, the threaded hole 17 and the threaded hole 18 will be aligned with each other, making it convenient for the staff to screw in the bolts for fixing, thus completing the assembly and fixing. Then, the staff starts the motor 8 to rotate the threaded rod 9, causing the threaded sleeve 10 that is threaded with the threaded rod 9 to slide in the hollow column 7, thereby causing the threaded sleeve 10 to pass through the mounting plate 4 and push the slider 16 through the connecting sleeve 11, causing the slider 16 to slide on the guide plate 15. Due to the extension of the overall length of the threaded sleeve 10 and the hollow column 7, the movable table 12 can be rotated around the fixed rod 6 at the same time, thereby adjusting the angle of the movable table 12 and changing the elevation angle of the radar body 14.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
