The gear transmission mechanism further comprises a horizontal fixing plate 12, the fixing plate 12 is located above the inner gear ring 6, the upper end of the driving shaft 1 is rotatably mounted on the fixing plate 12 and connected with a driving motor 13, and a core shaft of the straight gear 5 is rotatably mounted on the fixing plate 12.
The inner gear ring 6 is rotatably arranged on the fixed plate 12 through a bearing 14.
An annular baffle 15 is fixed on the outer side of the inner gear ring 6, a limiting end cover 16 positioned below the annular baffle 15 is sleeved outside the inner gear ring 6, and the upper end of the limiting end cover 16 is screwed on the fixing plate 12 through threads.
The lower surface of the fixing plate 12 is screwed with a spherical protective cover 17.
The camera 10 is a wide-angle camera.
When the invention is installed, firstly the inner gear ring 6 is installed on the bottom plate, the bearing 14 is installed between the inner gear ring and the bottom plate, then the end cover is screwed on the bottom plate, so that the inner gear ring 6 can freely rotate relative to the bottom plate and can not fall off, then the bottom plate is installed at a required position by using an expansion screw, then the protective cover 17 is screwed on, and the power supply of the motor and the camera 10 is switched on, and the power supply can adopt a storage battery or an external power supply.
Hereinafter, the clockwise or counterclockwise direction of the driving shaft 1, the ring gear 6 and the spur gear 5 when they rotate is based on the top view, and the clockwise or counterclockwise direction of the bevel gear 11 when it rotates is based on the big end view.
The working process of the invention is described below by taking the clockwise rotation of the driving shaft 1 as an example, and the incomplete gear 2 rotates once and is divided into four stages according to the time sequence: in the first stage, the incomplete gear 2 is not meshed with the inner gear ring 6 and the straight gear 5, at the moment, the first incomplete bevel gear 3 is meshed with the upper side of the bevel gear 11, the driving shaft 1 rotates to enable the first incomplete bevel gear 3 to drive the bevel gear 11 to rotate 180 degrees anticlockwise, the bevel gear 11 drives the U-shaped frame 8 and the camera 10 thereon to rotate 180 degrees anticlockwise through the transverse shaft 9, and the forward camera 10 rotates backwards through the lower part.
The driving shaft 1 rotates clockwise to enter a second stage, in the second stage, an incomplete gear is meshed with the straight gear 5, the first incomplete bevel gear 3 and the second incomplete bevel gear 4 are not meshed with the bevel gear 11, the incomplete gear 2 drives the straight gear 5 to rotate anticlockwise, the straight gear 5 drives the inner gear ring 6 to rotate 90 degrees anticlockwise, the inner gear ring 6 drives the U-shaped frame 8 and the camera 10 below the inner gear ring to rotate 90 degrees anticlockwise, the camera 10 rotates to the left from the backward anticlockwise, and the bevel gear 11 rotates to the rear side.
And the driving shaft 1 continuously rotates clockwise to enter a third stage, in the third stage, the incomplete gear 2 is not meshed with the inner gear ring 6 and the straight gear 5, at the moment, the second incomplete bevel gear 4 rotates to the rear side to be meshed with the lower side of the bevel gear 11, the second incomplete bevel gear 4 drives the bevel gear 11 to rotate clockwise by 180 degrees, the bevel gear 11 drives the U-shaped frame 8 and the camera 10 on the U-shaped frame to rotate clockwise by 180 degrees through the transverse shaft 9, and the camera 10 facing left rotates to the right through the lower side.
The driving shaft 1 continues to rotate clockwise to enter a fourth stage, in the fourth stage, the incomplete gear 2 is meshed with the inner gear ring 6, at the moment, the first incomplete bevel gear 3 and the second incomplete bevel gear 4 are not meshed with the bevel gear 11, the incomplete gear 2 drives the inner gear ring 6 to rotate clockwise by 90 degrees, the inner gear ring 6 drives the U-shaped frame 8 and the camera 10 below the inner gear ring to rotate 90 degrees along the pointer, the camera 10 rotates forwards from the pointer to the right along the direction of the right, and the bevel gear 11 rotates to the right side.
The four phases are a cycle, the driving shaft 1 continues to rotate to enter the next cycle, and in one cycle, the rotation path of the camera 10 is as follows: front → down → back, back → left, left → down → right, right → front, completing the monitoring in four directions, and sweeping below in the rotation process of the first stage and the third stage, so that the situation near the camera 10 is exposed in the monitoring visual field, as long as there is a person nearby, the monitoring of the camera cannot be avoided, at this moment, the blind area of the camera is above, so the illegal person cannot follow the blind area to continuously move near the camera 10 to avoid the monitoring of the camera 10.
The rotation path of the camera 10 is an unconventional path, and the blind area of the camera 10 on the ground is discontinuously changed in the rotation process of the camera 10, so that the situation that illegal persons can avoid monitoring along with the blind area of the camera 10 can be effectively prevented, one camera 10 can carry out all-around monitoring, and the equipment cost is reduced.
