Furthermore, any one of the cameras 3 is provided with a connecting shaft 31, the connecting shaft 31 is arranged in the rotating base 2 in a penetrating manner, and the surface of the rotating base 2 is provided with a guide cylinder 21 for supporting the connecting shaft 31; a coupler 22 for connecting the two connecting shafts 31 is arranged in the rotating seat 2, and the two connecting shafts 31 respectively penetrate through a bearing to be connected with the coupler 22; a second driving motor 23 is further installed in the rotary base 2, and a driving end of the second driving motor 23 is connected with one of the connecting shafts 31.

It should be noted that the present embodiment is an improvement on the driving mechanism and the mounting structure of the high-speed pan-tilt camera 3, and the operation and circuit principle of the camera 3 are conventional technical means in the field, and are not described herein again. Specifically, at first this embodiment has cancelled traditional turbine worm drive structure, adopts intermeshing's driving gear 43 and driven gear 44 structure, simple structure, and convenient processing and installation have improved production efficiency, have reduced manufacturing cost, and driving gear 43 and driven gear 44 all adopt 45 steel quenching and tempering and surface hardening to handle, have improved its mechanical strength, stand wear and tear, and the precision is high, improves its life. Secondly, two cameras 3 are installed on roating seat 2 through solitary connecting axle 31 respectively, have cancelled traditional single big logical axle construction, greatly reduced lead to the requirement of structure axiality, convenient processing promotes production efficiency, and overall structure design is simple, easy to assemble.

When the camera 3 needs to be driven to rotate horizontally, the first driving motor 41 drives the driving gear 43 to rotate, the driving gear 43 is meshed with the driven gear 44, wherein the first driving motor 41 and the driven gear 44 are installed on the rotary base 2 through the installation bracket 42, and the driven gear 44 is fixedly installed on the fixed base 1 through the installation shaft 11, therefore, when the first driving motor 41 drives the driving gear 43 to rotate, the driven gear 44 cannot rotate due to the fixed installation, so that the driving gear 43 revolves along the driven gear 44 while rotating, the rotary base 2 connected with the driving gear is driven to rotate around the fixed base 1, and the camera installed on the rotary base 2 can rotate.

When two cameras 3 need to be driven to rotate around the rotary base 2, the driving end of the second driving motor 23 drives one of the connecting shafts 31 to rotate, so that the camera 3 connected with the connecting shaft 31 is driven to rotate, meanwhile, the connecting shaft 31 is connected with the coupler 22, therefore, the coupler 22 can also rotate, and the other connecting shaft 31 is also connected with the coupler 22, therefore, the other camera 3 can also rotate along with the rotation, and therefore, the two cameras 3 can be driven to rotate around the rotary base 2 simultaneously through the driving of the second driving motor 23.
