The electric pan / tilt head is suitable for scanning and monitoring a large area. It can expand the monitoring range of the camera. The high-speed posture of the electric pan / tilt head is achieved by two actuator motors. The motor receives the signal from the controller to accurately operate and position. Under the action of the control signal, the camera on the pan / tilt head can automatically scan the monitoring area, and can also track the monitored object under the operation of the on-duty personnel in the monitoring center. The camera on the pan / tilt head has high shooting accuracy.

The connecting columns 8 A fan blade 9 is provided at the end away from the stabilizing block 7. When the wind blows the fan blade 9, the shielding plate 14 and the sliding rod 13 are driven by the fan blade 9 to rotate. The snow on the surface of the shielding plate 14 flies out and falls under the force of the rotation of the shielding plate 14, so as to avoid the accumulation of snow on the surface of the camera body 3 and cause the pan-tilt head to malfunction. A covering mechanism 10 is provided on the outer side of the mounting seat 1. The covering mechanism 10 includes an outer frame 16, a stabilizing column 17, and an inner ring 18. The outer frame 16 covers and blocks the gap between the mounting seat 1 and the rotating seat 2 to avoid the accumulation of dust and impurities and increase the occurrence rate of malfunctions.

[0024] In this embodiment, the connecting rod 5 includes a lower inclined portion, a middle connecting portion and an upper inclined portion. The lower inclined portion is parallel to the upper inclined portion. The inclined bottom end of the upper inclined portion is connected to the bottom block 11. The camera body 3 tilts and rotates up and down. When the camera body 3 rotates downward to the maximum, the inclined portion of the connecting rod 5 is parallel to the surface of the camera body 3, the camera body 3 will not touch the bottom block 11, and the fixed rod 12 and the sliding rod 13 are always in a vertical state.

[0025] In this embodiment, the top of the fixed rod 12 is a "T"-shaped structure, the sliding rod 13 is a hollow structure, the end of the sliding rod 13 away from the shielding plate 14 is sealed, the bottom end of the fixed rod 12 passes through the sliding rod 13 and is connected to the bottom block 11, one end of the spring 15 is connected to the shielding plate 14 and the other end is connected to the fixed rod 12. In rainy and snowy weather, the shielding plate 14 covers the upper side of the camera body 3 to prevent snow from accumulating on the surface of the camera body 3 and causing the pan / tilt head to malfunction.

[0026] In this embodiment, the fixed rod 12 and the sliding rod 13 slide vertically, the shielding plate 14 is in an arc shape, and six diversion grooves 20 are evenly distributed on the surface of the shielding plate 14 to facilitate the diversion and falling of rain and snow falling on the shielding plate 14.

[0027] In this embodiment, the stabilizing block 7 is screwed to the inner surface of the shielding plate 14 by screwing, one end of the connecting column 8 is screwed to the stabilizing block 7 by threaded connection and the other end is screwed to the fan blade 9 by screwing, the shielding plate 14 and the sliding rod 13 rotate 360 ​​degrees, the wind blows the fan blade 9 and drives the shielding plate 14 and the sliding rod 13 to rotate, and the snow on the surface of the shielding plate 14 flies out and falls under the force of the rotation of the shielding plate 14.

[0028] In this embodiment, the inner ring 18 is located on the outside of the mounting seat 1, and the outer frame 16 is located on the outside of the rotating seat 2. The length of the outer frame 16 is larger than the outer diameter of the inner ring 18. The stabilizing column 17 is located between the inner ring 18 and the outer frame 16.

[0030] In rainy and snowy weather, rain and snow fall on the surface of the shielding plate 14, snow accumulates, the shielding plate 14 and the sliding rod 13 move down, and the spring 15 is in a retracted state. The shielding plate 14 covers the upper side of the camera body 3 to prevent snow from accumulating on the surface of the camera body 3 and causing the pan / tilt head to malfunction. When the wind blows the fan blade 9, the shielding plate 14 and the sliding rod 13 are driven by the fan blade 9 to rotate, and the snow on the surface of the shielding plate 14 flies out and falls under the force of the rotation of the shielding plate 14. The spring 15 stretches from the retracted state, and the snow on the shielding plate 14 vibrates and falls under the action of the spring 15;

[0031] When the camera body 3 and the rotating base 2 on the pan / tilt head rotate in the horizontal direction, the stabilizing column 17 moves in a circle along the inner ring 18, and the outer frame 16 covers the gap between the mounting base 1 and the rotating base 2 to prevent dust and impurities from accumulating and increasing the failure rate.
