Description

Technical Field

[0001] The invention relates to the field of radar antennas, and in particular to a radar base. Background Art

[0002] Radars often need to be adjusted in angle during use, including horizontal and vertical angle adjustments. In order to facilitate the adjustment of the radar angle, the connection stability between the radar and the base is often not very high. Especially for large radars, unreliable connections can easily cause them to be damaged in severe weather such as typhoons and rainstorms.

[0003] In particular, the pot-shaped radar not only has a large wind-exposed area, but is also prone to water accumulation inside, causing the overall weight to increase and the center of gravity to shift upward, making it more susceptible to damage in windy and rainy weather.

The independent disc is usually blocked in the circular hole and forms a whole with other parts, but it automatically opens after the radar is reset in stormy weather, exposing the circular hole, draining the rainwater stored in the radar, and reducing the impact of wind and rain on the radar.

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0025] like Figures 1 to 6 As shown, the present invention comprises a rotating platform 2, an angle-adjusting base 3 and a base 4, wherein a radar body 1 is fixedly mounted on the rotating platform 2, and the rotating platform 2 is rotatably connected to the angle-adjusting base 3 through a connecting tube 5, and the angle-adjusting base 3 is rotatably connected to a base movable groove 8 in the base 4;

[0026] The base 4 is provided with symmetrically arranged hydraulic cylinders 10, the output rods 11 of the two hydraulic cylinders 10 are movably connected to the lower end of the angle adjustment base 3, and the input rods 13 of the two hydraulic cylinders 10 are connected to the output shaft of the hydraulic press 16 through the driving lever 15;

[0027] The hydraulic press 16 is used as the driving part of the vertical plane angle adjustment, which is more stable, and there is a pair of symmetrical hydraulic cylinders 10 as a transition between the hydraulic press 16 and the angle adjustment base 3, so that the vertical plane angle adjustment mechanism is more stable and has better balance. The hydraulic press 16 and the output rods of the two hydraulic cylinders 10 are connected through the driving lever 15, which reduces the instantaneous output of the hydraulic press 16 and prevents cylinder explosion.

[0028] As for the angle adjustment of the horizontal plane, since the resistance is small, it is directly driven by a motor, and the control is more flexible. The rotating motor 21 is arranged in the angle adjustment base 3, and the output shaft of the rotating motor 21 is connected to the rotating platform 2.

[0029] The bottom recessed portion of the base movable groove 8 can be connected to the outside through multiple drainage pipes 17, one of which is connected to an inner cylinder 18 arranged in the base 4. A floating plate 19 is slidably connected in the inner cylinder 18, and a control button 20 is provided on the top of the inner cylinder 18. The control button 20 is connected to the switch circuit of the hydraulic press 16, and the control button 20 is also connected to the power circuit of the rotating motor 21.

[0030] When the rainfall is heavy, the drainage pipe 17 will drain water rapidly, the water pressure inside will increase, and water will enter the inner tube 18, causing the floating plate 19 to float up and finally press the control button 20, causing it to be pressed.

[0031] The control button 20 can turn off the hydraulic press 16 and the rotating motor 21. After the control button 20 is pressed, the hydraulic press 16 and the rotating motor 21 will stop working, stop the angle adjustment work, and reset to the most stable position to reduce damage in wind and rain.

[0032] In particular, the present invention cuts out an independent circular piece 6 on the radar body 1, and a hard water pipe 7 is also connected to the radar body 1, the upper end of the hard water pipe 7 is connected to the circular hole generated after cutting out the independent circular piece 6, and the lower end of the hard water pipe 7 is connected to the inner cavity of the connecting tube 5, and the angle adjustment base 3 is also provided with a drainage channel 22 connecting the inner cavity of the connecting tube 5 and the base movable groove 8.

[0033] The independent disc 6 is usually blocked in the round hole and forms a whole with other parts, but it opens automatically after the radar is reset in stormy weather, exposing the round hole to drain the rainwater stored in the radar and reduce the impact of wind and rain on the radar.

[0034] The principle of the independent disc 6 opening automatically in stormy weather is that a movable bracket 27 is slidably connected in the hard water pipe 7, and a fixed bracket 28 is fixedly connected to the inner wall of the hard water pipe 7 below the movable bracket 27, a spring 29 is connected between the movable bracket 27 and the fixed bracket 28, and the upper end of the movable bracket 27 is fixedly connected to the independent disc 6 through a connecting rod 26. In addition, an inner groove is provided in the rotating platform 2, and an electromagnet 23 is fixedly provided at the bottom of the inner groove, and a metal block 24 is slidably connected in the inner groove, and the metal block 24 is connected to the lower end of the movable bracket 27 through a cable 25, and the control button 20 is also connected to the power circuit of the electromagnet 23. A buffer pad 30 is provided at the front end of the electromagnet 23.

[0035] After the control button 20 is pressed, the electromagnet 23 is closed so that the metal block 24 is no longer affected by the magnetic force, the elastic force of the spring 29 is released, and the movable bracket 27 lifts the independent disc 6 through the connecting rod 26, exposing the circular hole for drainage. The rainwater in the radar can pass through the hard water pipe 7 through the inner cavity of the connecting tube 5, the drainage channel 22, the base movable groove 8, and finally be discharged through the drainage pipe 17.

[0036] It should be explained in detail that the inner end of the input rod 13 is fixedly connected to the input piston 14, the inner end of the output rod 11 is fixedly connected to the output piston 12, the output piston 12 and the input piston 14 are both slidably connected in the hydraulic cylinder 10, and the space between the two is filled with liquid. The base 4 is also provided with an air path connecting the inner cylinder 18 with the external atmosphere. The output rod 11 is movably connected to the angle adjustment base 3 through the base connecting member 9, the bottom of the base connecting member 9 is rotatably connected to the output rod 11, and the top of the base connecting member 9 is slidably connected to the angle adjustment base 3.

[0037] Specific implementation and principle:

[0038] The hydraulic press 16 is used as the driving part for the vertical angle adjustment, and a pair of symmetrical hydraulic cylinders 10 are provided between the hydraulic press 16 and the angle adjustment base 3 as a transition, so that the vertical angle adjustment mechanism is more stable and has better balance. As for the horizontal angle adjustment, the resistance is small, so the rotary motor 21 is directly used to drive. In order to facilitate the movement of the angle adjustment base 3, a base movable groove 8 is provided, and in order to drain the accumulated water in the base movable groove 8, a drainage pipe 17 is provided.

[0039] When the precipitation is heavy, the drainage pipe 17 will drain quickly, the water pressure inside will increase, and the water will enter the inner tube 18, causing the floating plate 19 to float up, and finally press the control button 20, so that it is pressed. The control button 20 can turn off the hydraulic press 16, the rotating motor 21 and the electromagnet 23. After the control button 20 is pressed, the hydraulic press 16 and the rotating motor 21 will stop working, so that the angle adjustment work is stopped and reset to the most stable position, reducing the damage received in the wind and rain.

[0040] When the electromagnet 23 is turned off, the metal block 24 is no longer affected by the magnetic force, and the movable bracket 27 will not be pulled down through the cable 25, causing the independent disc to be blocked in the circular hole; therefore, the elastic force of the spring 29 is released, and the movable bracket 27 lifts the independent disc 6 through the connecting rod 26, exposing the circular hole for drainage. The rainwater in the radar can pass through the hard water pipe 7 through the inner cavity of the connecting tube 5, the drainage channel 22, the base movable groove 8, and finally be discharged through the drainage pipe 17.

[0041] Based on the above, the present invention will automatically disconnect the active mechanism for adjusting the radar angle in the case of heavy rainfall, so that the radar will reset to the most stable position and remain stable, reducing damage. At the same time, an independent disc is cut out at the lowest end of the radar when it is in the most stable position to create a circular hole for drainage. The independent disc is usually blocked in the circular hole and forms a whole with other parts, but it will automatically open after the radar is reset in stormy weather, exposing the circular hole, draining the rainwater stored in the radar, and reducing the impact of wind and rain on the radar.

[0042] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
