The turntable can drive the detection assembly to rotate to adjust different detection directions and expand the detection range, and is commonly used in various scenarios such as shipborne monitoring, vehicles, forest fire prevention, and environmental monitoring.

[0003] In the prior art, in order to enable the photoelectric turntable to realize panoramic detection, the detection assembly is usually enabled to rotate 360° in the horizontal direction and the vertical direction. However, when the detection assembly faces downward, it faces the base. When the detection assembly needs to face backward, it only needs to be rotated 180° in the horizontal direction, without being rotated 180° in the vertical direction. Therefore, in actual application, the detection assembly does not need to be rotated 360° in the vertical direction to realize panoramic monitoring. However, the photoelectric turntable on the market causes repetition of the path, which is not conducive to improving the adjustment efficiency. Moreover, when the detection assembly faces downward, the field of view is lost, which is not conducive to improving the monitoring capability of the photoelectric turntable. SUMMARY

[0012] In a possible implementation, a second blocking piece is arranged on the restrictor, the second blocking piece is located between two adjacent first fixed columns, and the second blocking piece is in contact with the first fixed column after the first blocking piece triggers the sensor.

[0013] In a possible implementation, the rotation range of the ball head is -30° to 90°.

[0014] In a possible implementation, a second fixed column is arranged on the fixed arm, and the sensor is arranged on the second fixed column.

[0036] The utility model discloses the beneficial effect lies in: through setting up the limiter 41 and the sensor 26 that cooperates with the limiter 41 on the rotating shaft 4, make the ball head 3 rotate by certain angle, the limiter 41 is triggered, thereby make the ball head 3 stop rotating, and then avoid the front of the ball head 3 to the base 1, cause the loss of field of view, be favorable to improve the monitoring ability of photoelectric turntable.

[0037] Please refer to Figure 3 In a possible implementation, the fixed arm 21 is provided with a plurality of first fixing columns 22, the first fixing column 22 is provided with a PCB 27, and the sensor 26 is electrically connected with the PCB 27. It should be noted that the plurality of first fixing columns 22 are arranged at intervals, the first fixing column 22 is arranged to provide a mounting basis for the PCB 27, and the PCB 27 is arranged on the outer side of the limiter 41, which is conducive to improving the space utilization.

[0038] Please refer to Figure 2In a possible implementation, the other fixed arm 21 is provided with a vertical motor 5, the driving end of the vertical motor 5 is connected with the ball head 3, and the vertical motor 5 is electrically connected with the PCB 27. It should be noted that the vertical motor 5 is installed on the inner wall of the fixed arm 21 through bolts, and the vertical motor 5 is used to drive the ball head 3 to rotate in the vertical direction. When the ball head 3 rotates, the rotating shaft 4 rotates together with the ball head 3, and the limiter 41 rotates together with the rotating shaft 4. When the first baffle 411 triggers the sensor 26, a signal is sent to the PCB 27, and the PCB 27 sends a stop signal to the vertical motor 5, so that the ball head 3 stops rotating.

[0039] Please refer to Figure 2 In a possible implementation, the ball holder 2 is provided with a horizontal motor 6, the driving end of the horizontal motor 6 is connected with the base 1, and the horizontal motor 6 is electrically connected with the PCB 27.

[0040] Please refer to Figure 5 In a possible implementation, the limiter 41 is provided with a second baffle 412, the second baffle 412 is located between two adjacent first fixed columns 22, and the second baffle 412 contacts the first fixed column 22 after the first baffle 411 triggers the sensor 26. It should be noted that the second baffle 412 is arranged in a spaced manner with the first baffle 411, the second baffle 412 is also an integral structure with the limiter 41, the second baffle 412 is L-shaped to facilitate the contact between the second baffle 412 and the first fixed column 22. When the ball head 3 rotates downward to the limit distance, the second baffle 412 contacts the first fixed column 22, thereby preventing the ball head 3 from continuing to rotate downward. When the ball head 3 rotates upward to the limit distance, the second baffle 412 contacts the other first fixed column 22, thereby preventing the ball head 3 from continuing to rotate upward.

It should be noted that the fixed ring 42 is mounted on the end face of the rotating shaft 4 through a bolt, and the restrictor 41 is located between the fixed ring 42 and the rotating shaft 4. After the bolt is tightened, the restrictor 41 and the fixed ring 42 are fixed on the rotating shaft 4 together. When the restrictor 41 needs to be replaced due to wear, the fixed ring 42 can be removed, which is very convenient.

[0044] Please refer to Figure 4 In a possible implementation, the outer surface of the ball bracket 2 has an arc surface 25, the arc surface 25 is located below the ball head 3, and the two ends of the arc surface 25 are connected to the two fixed arms 21 respectively.
