Technical Field

[0001] The utility model relates to the technical field of antenna turntables, in particular to a radar antenna turntable with a limiting device. Background Art

[0002] Radar means "radio detection and ranging", that is, using radio methods to detect targets and determine their spatial positions. Therefore, radar is also called "radio positioning". Radar is an electronic device that uses electromagnetic waves to detect targets. Radar emits electromagnetic waves to illuminate the target and receives its echo, thereby obtaining information such as the distance from the target to the electromagnetic wave emission point, the rate of change of distance (radial velocity), direction, altitude, etc.

[0003] Radar equipment usually needs to be equipped with a radar turntable, which drives the radar to rotate to achieve all-round scanning detection. Existing radar equipment is installed by multiple bolts. When the radar needs maintenance, maintenance personnel need to use tools to remove multiple bolts, which takes a lot of time and makes the radar maintenance inconvenient. Therefore, a radar antenna turntable with a limit device is proposed. Utility Model Content

[0025] Example

[0026] See also Figure 1-5 The utility model provides a technical solution: a radar antenna turntable with a limiting device, comprising an antenna turntable body 1, a shell 4 is arranged on one side of the antenna turntable body 1, a base 5 is installed at the bottom of the shell 4, a mounting plate 3 is installed at the top movable end of the shell 4, and a limiting component 2 for clamping and fixing the radar is arranged on one side of the top of the mounting plate 3;

[0027] In order to facilitate the disassembly and assembly of the radar, a limit assembly 2 is provided. The limit assembly 2 includes two fixed plates 21, a motor 24 and a prompt mechanism. A second slide groove 216 is provided inside the fixed plate 21. A slide plate 29 is slidably connected to the inner side of the second slide groove 216. A bidirectional screw rod 25 is fixed to the output shaft end of the motor 24 to control the rotation of the output shaft of the motor 24. At this time, the output shaft drives the bidirectional screw rod 25 to rotate. At this time, the bidirectional screw rod 25 is threadedly connected to the two fixed plates 21 respectively. A rubber plate 22 that runs through one side of the fixed plate 21 is bonded to one side of the slide plate 29. One side of the two rubber plates 22 is respectively attached to the two sides of the bottom of the radar. A first slide groove 23 is provided on the top of the mounting plate 3. The outer side of the bidirectional screw rod 25 is rotatably connected to the inner side of the first slide groove 23 through a bearing. The bottom of the fixed plate 21 is slidably connected to the inner side of the first slide groove 23. The fixed plate 21 slides inside the first slide groove 23. When the output shaft of the motor 24 rotates clockwise, the two fixed plates 21 are moved away from each other. At this time, the square base of the radar can be loosened.

[0028] In order to facilitate the prompting of the clamping state, a prompting mechanism is provided, which includes a slide post 211, and the inner walls of the second slide groove 216 are respectively provided with a first limiting groove 28 and a second limiting groove 214, a limiting plate 213 is fixed on one side of the slide post 211, and a limiting block 215 is fixed on the other side of the slide post 211, and a switch 27 is installed on the inner wall of the first limiting groove 28, and a second spring 212 is connected between one side of the switch 27 and the slide post 211. When one side of the rubber plate 22 is squeezed by the radar base, the slide plate 29 slides inside the second slide groove 216, and the first spring 210 is pressed. Compression, when the first spring 210 is compressed to the shortest length, the slide plate 29 abuts against one side of the limit plate 213, an indicator light 26 is installed on one side of the fixed plate 21, and the output end of the switch 27 is electrically connected to the input end of the indicator light 26. The indicator light 26 generates a light prompt to actively inform the staff that the limit assembly 2 has clamped the radar base. When the radar base is clamped, the rubber plate 22 is squeezed and finally triggers the switch 27, causing the indicator light 26 to generate a light prompt. The real-time feedback mechanism can immediately inform the staff that the radar base has been clamped without additional inspection or confirmation.

[0029] The outer side of the limiting plate 213 is adapted to the inner side of the second limiting groove 214, the limiting block 215 is located on the inner side of the first limiting groove 28, a first spring 210 is connected between one side of the slide plate 29 and the inner side of the second slide groove 216, the outer side of the slide column 211 moves through the inner wall side of the first limiting groove 28, and one side of the motor 24 is fixed to one side of the mounting plate 3.

[0030] The model of the antenna turntable body 1 is: VT-M15;

[0031] The output shaft end of the motor 24 has a locking structure, and the model of the motor 24 is: ASF102A.

[0032] Working principle or structural principle: When the antenna turntable body 1 is working, the incremental encoder built into the shell 4 realizes closed-loop control, and the shell 4 is made of high-strength aluminum alloy die-casting material, and the antenna turntable body 1 adopts worm gear transmission, which can be self-locking when the power is off. At this time, the radar is installed between the two fixing plates 21, so that the two rubber plates 22 clamp and limit the square base of the radar;

[0033] When the square base of the radar is placed on the top of the mounting plate 3, the switch is pressed to control the output shaft of the motor 24 to rotate. At this time, the output shaft drives the bidirectional screw rod 25 to rotate. At this time, the bidirectional screw rod 25 is respectively threadedly connected with the two fixing plates 21, so that the fixing plate 21 slides inside the first slide groove 23. When the output shaft of the motor 24 rotates clockwise, the two fixing plates 21 move away from each other. At this time, the square base of the radar can be loosened. When the output shaft of the motor 24 rotates counterclockwise, the two rubber plates 22 are close to the square base of the radar. At this time, the base of the radar can be clamped and limited. The operation is simple and convenient, and the radar can be easily disassembled and assembled, which is convenient for the staff to maintain the radar. The two rubber plates 22 clamp the radar base, which can provide a stable clamping force to prevent the radar from shifting or shaking during use, thereby ensuring the stable operation of the radar. Since the disassembly and assembly operation is simple and quick, the staff can easily maintain, inspect and replace parts of the radar, thereby improving the convenience of radar maintenance.

[0034] When the base of the radar is in the clamping limit position, one side of the rubber plate 22 is squeezed by the radar base, so that the slide plate 29 slides inside the second slide groove 216, and the first spring 210 is compressed. When the first spring 210 is compressed to the shortest length, the slide plate 29 abuts against one side of the limit plate 213, and the limit plate 213 pushes the slide post 211 to move to the side of the switch 27, so that the slide post 211 triggers the switch 27, and the slide post 211 compresses the second spring 212. At this time, the limit plate 213 moves to the inside of the second limit groove 214. After the switch 27 is triggered, the indicator light 26 generates a light prompt, actively informing the staff that the limit assembly 2 has clamped the radar base. When the radar base is clamped, the rubber plate 22 is squeezed, and finally the switch 27 is triggered, so that the indicator light 26 generates a light prompt. The real-time feedback mechanism can immediately inform the staff that the radar base has been clamped without additional inspection or confirmation, thereby avoiding radar displacement or damage caused by loose clamping and improving operational safety.
