[0034] The technical solution of the utility model includes a base 1 and an electric pan-tilt head 2 arranged on the base 1, and the electric pan-tilt head 2 can be divided into a horizontal rotation module and a vertical rotation module. By arranging a second camera module 5 on the vertical rotation module, the horizontal rotation module can drive the vertical rotation module and the second camera module 5 thereon to rotate horizontally, and its horizontal rotation angle is 0°~350°, and the vertical rotation module can drive the second camera module 5 thereon to rotate vertically, and its vertical rotation angle is +90°, so that the monitoring device can not only rotate horizontally, but also combine the cooperation of horizontal rotation and vertical rotation to realize the shooting of the monitoring device in all directions, and the monitoring range is large; wherein, the first camera module can be a wide-angle lens to realize monitoring of a large range of scenes or the entire scene, and the second camera module can be a telephoto lens to realize magnification of objects in the wide-angle lens scene, reflecting more efficient intelligent monitoring;

[0035] More specifically, through the arrangement of the first wiper assembly 4 and the second wiper assembly 6, the first wiper assembly 4 and the second wiper assembly 6 can respectively effectively clean the dust and mist (water droplets) on the surface (i.e., the camera lenses) of the first camera module 3 and the second camera module 5, thereby reducing the interference of external factors on the monitoring device, effectively ensuring the camera effect of the first camera module 3 and the second camera module 5, and helping to improve the monitoring function.

[0036] More specifically, in the embodiment of the utility model, the first wiper assembly 4 and the second wiper assembly 6 respectively include a motor 7, an L-shaped shaft 8 connected to the output shaft of the motor 7, and a wiper head 9 connected to the L-shaped shaft 8; wherein, the L-shaped shaft 8 and the wiper head 9 are driven by the motor 7 so as to swing along the periphery of the first camera module 3 / the second camera module 5;

[0037] The L-shaped rotating shaft 8 includes a rotating end 10 dynamically connected to the output shaft of the motor 7 and a swinging end 11 connected to the rotating end 10, and the wiper head 9 is connected to the swinging end 11; wherein, the base 1 and the electric pan-tilt head 2 are both equipped with an assembly position corresponding to the motor 7, and one end of the rotating end 10 away from the output shaft of the motor 7 is exposed through the base 1 / electric pan-tilt head 2, so that the swinging end 11 and the wiper head 9 are located on the surface of the first camera module 3 / second camera module 5.

[0038] By having assembly positions for the motor 7 built into the base 1 and the electric pan / tilt head 2, combined with the L-shaped shaft 8 that is power-connected to the output shaft of the motor 7 and the wiper head 9 that is connected to the L-shaped shaft 8, the swing end 11 of the L-shaped shaft 8 and the wiper head 9 thereon can accurately act on the surface of the first camera module 3 / the second camera module 5, and under the drive of the motor 7, the rotating end 10 of the L-shaped shaft 8 can rotate along with it, and the swing end 11 of the L-shaped shaft 8 and the wiper head 9 thereon can move accordingly, thereby achieving effective cleaning of dust and fog (water droplets) on the surface of the first camera module 3 / the second camera module 5, and the structural design of the first wiper assembly 4 / the second wiper assembly 6 is simple and practical.

[0039] Furthermore, the motor 7 can be a stepper motor 7 or a servo motor 7 to accurately control the amplitude and speed of the swing of the wiper head 9, wherein the first wiper assembly 4 and the second wiper assembly 6 are electrically connected to the PCB boards of the first camera module 3 and the second camera module 5, respectively, so as to be controlled through corresponding program control. For example, the start and stop of the first wiper assembly 4 and the second wiper assembly 6 can be controlled through the cloud platform based on human identification, and corresponding sensors (such as rain sensors) can be added to the first camera module 3 / the second camera module 5 to control the start and stop of the first wiper assembly 4 and the second wiper assembly 6.

[0040] More specifically, in the embodiment of the utility model, the assembly position has two threaded columns 12 arranged opposite to each other, and a mounting groove 13 located between the two threaded columns 12, the motor 7 is placed in the mounting groove 13, and both ends of the motor 7 have connection ends 14 corresponding to the threaded columns 12.

[0041] The motor 7 is fixed by accurately positioning the motor 7 through the mounting groove 13 and screwing the threaded column 12 to the connecting end 14. This not only facilitates assembly but also effectively ensures the stability of the swing of the wiper head 9, thereby avoiding damage to the lens surface of the first camera module 3 / the second camera module 5.

[0047] The wiper head 9 is made of a colloid material, such as rubber or silicone. The wiper head 9 can be installed in the assembly groove 18 on the L-shaped shaft 8, and the wiper head 9 can be limited and abutted with the step structure 19 in the assembly groove 18 through the limiting edge 24 of the wiper head 9 itself. Not only is the assembly convenient, but it can also effectively ensure the firmness of the connection between the wiper head 9 and the L-shaped shaft 8, thereby ensuring the cleaning effect of the first wiper assembly 4 and the second wiper assembly 6.

[0049] By providing the first connection end 25 and the second connection end 26, the connection area between the wiper head 9 and the L-shaped shaft 8 is effectively increased, thereby effectively preventing the wiper head 9 from being easily separated from the L-shaped shaft 8, thereby facilitating the cleaning effect of the first wiper assembly 4 and the second wiper assembly 6.

[0050] More specifically, in the embodiment of the utility model, a receiving groove 27 corresponding to the first wiper assembly 4 is provided on the base 1 and below the first camera module.

[0051] Similarly, when the rotation space of the electric pan-tilt head 2 allows, a storage groove 27 corresponding to the second wiper assembly 6 is provided on the electric pan-tilt head 2 and below the second camera module 5. Thus, through the setting of the storage groove 27, the first wiper assembly 4 / the second wiper assembly 6 can be stored when the first wiper assembly 4 and the second wiper assembly 6 are not needed, which is not only beneficial to the aesthetics but also effectively reduces the error of the first wiper assembly 4 / the second wiper assembly 6 blocking the first camera module 3 / the second camera module 5.
