[0030] In the specific implementation process, such as Figures 1-8As shown, the system includes an automatic horizontal adjustment mechanism. A first boom 1 and a second boom 2 are located on both sides of the bottom of the automatic horizontal adjustment mechanism. Multiple threaded holes 3 are provided at the top and bottom of both the first boom 1 and the second boom 2, and bolts are inserted into these holes. The tops of the first boom 1 and the second boom 2 are connected to the automatic horizontal adjustment mechanism via multiple bolts. An automatic pitch adjustment mechanism is installed at the bottom of the first boom 1 and the second boom 2 via multiple bolts. A camera mechanism is mounted on the automatic pitch adjustment mechanism. A protective device is detachably connected around the outside of the first boom 1 and the second boom 2. The protective device includes two detachably connected top protective components. The top protection assembly includes a first bottom protection component and a second bottom protection component. The top protection component comprises a connecting frame 4, two upright plates 5, and two arc-shaped plates 6. The two upright plates 5 are fixedly connected by the connecting frame 4. Multiple elastic telescopic components are provided on the connecting frame 4 and the two upright plates 5 at positions corresponding to the threaded holes 3 at the top of the first boom 1 or the top of the second boom 2. The two arc-shaped plates 6 are respectively fixed to the side walls of the two upright plates 5, and multiple heat dissipation copper fins 7 are installed on each of the two arc-shaped plates 6. The first bottom protection component includes a first center plate 8 and two first arc-shaped frames 9. The two first arc-shaped frames 9 are respectively fixed to the two upright plates 5, and their bottom ends are jointly fixedly connected to the top protection component. The first center plate 8 has an elastic telescopic component at the position corresponding to the threaded hole 3 at the bottom end of the first boom 1. The second bottom end protection component includes a second center plate 10 and two second arc-shaped frames 11. The two second arc-shaped frames 11 are respectively fixed to two upright plates 5, and the bottom ends of the two second arc-shaped frames 11 are jointly fixed to the second center plate 10. The second center plate 10 has an elastic telescopic component at the position corresponding to the threaded hole 3 at the bottom end of the second boom 2. When using this device, the two arc-shaped plates 6 can be assembled together around the yaw motor rotor 16, and bolts are inserted into the ends of the two arc-shaped plates 6. The other end of the bolts is tightened with a nut. One end is connected in the same way. After the connection is completed, the ends of multiple heat dissipation copper fins 7 are in contact with the yaw motor rotor 16, which facilitates the heat dissipation of the yaw motor rotor 16. After the protective device is installed on the photoelectric pod, by attaching the connecting frame 4, the two upright plates 5, and the first center plate 8 to the top and bottom of the second boom 2, and by attaching the connecting frame 4, the two upright plates 5, and the second center plate 10 to the top and bottom of the second boom 2, rainwater is less likely to enter the threaded hole 3, reducing the corrosion of the bolts by rainwater. In addition, rubber gaskets can be installed on the connecting frame 4, the two upright plates 5, the first center plate 8, and the second center plate 10 to enhance the sealing and reduce the infiltration of rainwater.
[0031] The elastic telescopic component includes a spring 12 and a pressing post 13. One end of the pressing post 13 is movably disposed in the groove of the connecting frame 4. The two ends of the spring 12 are respectively fixedly connected to the bottom wall of the groove of the connecting frame 4 and the end of the pressing post 13. After the protective device is installed on the photoelectric pod, multiple elastic telescopic components are respectively located in multiple threaded holes 3. The spring 12 is in a compressed state, and one end of the pressing post 13 is pressed against the head of the bolt, so that the bolt is not easy to loosen due to vibration or other reasons during long-term use. The pressing post 13 of the elastic telescopic component installed at the positions of the upright plate 5, the first center plate 8 and the second center plate 10 is respectively disposed in the groove of the upright plate 5, the first center plate 8 and the second center plate 10. It will not be described in detail here.
[0032] The automatic horizontal adjustment mechanism includes a yaw motor stator 15 and a yaw motor rotor 16. A yaw motor top cover 14 is mounted on the top of the yaw motor stator 15, a yaw motor coil 17 is mounted inside the yaw motor stator 15, and the yaw motor rotor 16 is mounted on the bottom of the yaw motor stator 15. A yaw motor magnetic core 20 and a yaw motor drive board 21 are also mounted on the yaw motor stator 15. A first double-row bearing 18 and a yaw motor magnet bracket 19 are also mounted on the yaw motor rotor 16. The two sides of the yaw motor rotor 16 are respectively connected to the first double-row bearing 18 by multiple bolts. The boom 1 and the second boom 2 are equipped with a yaw motor lower cover plate 22 below the yaw motor drive plate 21. When the current passes through the yaw motor coil 17 on the yaw motor stator 15, the yaw motor coil 17 generates a magnetic field. This magnetic field interacts with the magnet (or electromagnet) on the yaw motor rotor 16 to generate a rotational torque. The yaw motor rotor 16 starts to rotate under the action of the magnetic field. The friction is reduced by the first double row bearing 18 to ensure smooth rotation. The yaw motor drive plate 21 adjusts the direction and magnitude of the current through the control circuit, thereby controlling the rotational speed and direction of the rotor.
[0033] The pitch attitude automatic adjustment mechanism includes a pitch motor stator 23, a pitch motor rotor 24, and a bearing housing 25. The pitch motor stator 23 and the bearing housing 25 are respectively mounted on the first boom 1 and the second boom 2. An intermediate housing 34 is rotatably connected between the pitch motor stator 23 and the bearing housing 25. The pitch motor rotor 24 is connected to the intermediate housing 34. A pitch motor coil 26 is installed inside the pitch motor stator 23. The pitch motor rotor 24 is installed on the pitch motor stator 23. A pitch motor magnetic core 27 and a pitch motor drive plate 28 are also installed on the pitch motor stator 23. A second double-row bearing 29 and a pitch motor magnet bracket 30 are also installed on the pitch motor rotor 24. The operating principle of the pitch attitude automatic adjustment mechanism can be referred to the operating principle of the horizontal automatic adjustment mechanism.
[0034] The camera mechanism includes a visible light lens 31 and an infrared detector lens 32, both of which are mounted on the intermediate housing 34. A gyroscope 33 is also mounted below the infrared detector lens 32. The automatic horizontal adjustment mechanism can drive the visible light lens 31 and the infrared detector lens 32 to rotate horizontally, and the automatic pitch adjustment mechanism can drive the visible light lens 31 and the infrared detector lens 32 to rotate downwards. The gyroscope 33 can sense changes in the attitude of the pod (such as tilting or rotating). Even when the mounting platform itself moves or vibrates, the optoelectronic pod can maintain a relatively stable viewing angle, ensuring continuous and accurate target tracking and observation.
