[0023] like Figures 1-4As shown, this utility model provides a technical solution: a visual recognition device, including a mounting plate 1, a protective tube 2 fixedly connected to the bottom of the mounting plate 1, a first servo motor 5 fixedly connected to the bottom of the mounting plate 1 near the middle, a threaded rod 7 fixedly connected to the bottom end of the output shaft of the first servo motor 5, a movable tube 6 sleeved on the threaded rod 7, the inner wall of the movable tube 6 having a thread matching the threaded rod 7, a movable plate 19 fixedly connected to the bottom end of the movable tube 6, a circular block 3 fixedly connected to the bottom of the movable plate 19 via a connecting rod, a rotating plate 9 movably connected to the bottom of the circular block 3, and the bottom of the rotating plate 9 moving via a shaft and bearing. The identification device body 4 is connected to the top of the movable plate 19, near the left and right sides, and limit tubes 18 are fixedly connected. Limit rods 17 are set inside the limit tubes 18. The top of the limit rods 17 is fixedly connected to the bottom of the mounting plate 1. Limit blocks 22 are fixedly connected to the side walls of the limit rods 17 near the bottom. Limit grooves matching the limit blocks 22 are opened on the left and right side walls of the limit tubes 18. An electric protective door 8 is installed at the bottom of the protective tube 2. A connecting block is fixedly connected to the top of the electric protective door 8 near the right side. The front and rear walls of the connecting block are movably connected to the fixing blocks through the rotating shaft and bearing. The side wall of the fixing block is fixedly connected to the side wall of the protective tube 2.

[0024] In this embodiment, through the cooperation between the first servo motor 5, the threaded rod 7, and the movable tube 6, the first servo motor 5 can drive the threaded rod 7 to rotate, thereby driving the lower component to move vertically through the movable tube 6. This facilitates moving the identification device body 4 downward to the lower part of the protective tube 2 for use and moving it upward into the protective tube 2 for protection.

[0025] like Figures 1-4 As shown, a connecting plate 10 is fixedly connected to the top of the rotating plate 9 near the front and rear. A rotating shaft 11 is fixedly connected between the two connecting plates 10 near the top. Limiting wheels 13 are movably connected to the top of the rotating plate 9 near the left and right sides through connecting blocks, rotating shafts and bearings. An arc-shaped limiting groove matching the limiting wheel 13 is opened at the bottom of the circular block 3. A circular slot is opened inside the circular block 3. A first worm gear 12 is set in the circular slot. The rear end of the rotating shaft 11 passes through the front wall of the first worm gear 12. A first worm 20 is meshed in the core of the top of the first worm gear 12. Both ends of the first worm 20 are movably connected to the inner wall of the circular slot through bearings. A second servo motor 21 is fixedly connected to the right end of the first worm 20 through the inner ring of the bearing. An installation slot matching the second servo motor 21 is opened inside the circular block 3.

[0026] In this embodiment, through the cooperation between the second servo motor 21, the first worm gear 12, and the first worm 20, the second servo motor 21 can rotate in both directions to drive the first worm 20 and the first worm gear 12 to rotate, thereby driving the recognition device body 4 to adjust the vertical angle. Through the cooperation between the third servo motor 14, the second worm gear 16, and the second worm 15, the recognition device body 4 can adjust the horizontal angle.

[0027] Working principle: When using this technical solution, the device is installed in a suitable position using the mounting plate 1. In use, first open the electric protective door 8, and start the first servo motor 5 to drive the threaded rod 7 to rotate. At this time, the movable tube 6 drives the component below it to move downward. Through the cooperation between the limit rod 17 and the limit tube 18, the stability of the movable plate 19 and the component below it during movement can be ensured. Start the second servo motor 21 to drive the first worm 20 to drive the first worm wheel 12 and the connecting plate 10 to rotate, which in turn drives the rotating plate 9 and the identification device body 4 to rotate vertically. Start the third servo motor 14 to rotate through the second worm wheel 16 and the second worm 15, which in turn drives the identification device body 4 to rotate horizontally.
