[0024] Specifically, the housing 2 plays the role of fixing the motor 3. One end of the worm 4 is connected to the output end of the housing 2. The starting motor 3 drives the worm 4 to rotate. The other end of the worm 4 rotates inside the housing 2, which can support the rotation of the worm 4. The worm 4 drives the transmission shaft 6 to rotate through the worm gear 5. The housing 2 supports one end of the transmission shaft 6 to rotate. The other end of the transmission shaft 6 penetrates the housing 2 to drive the connecting rod 7 to rotate. The connecting rod 7 drives the sliding frame 8 to slide through the connecting rod 21. A limiting groove is provided inside the limiting frame 9. The sliding frame 8 slides in the limiting groove of the limiting frame 9. The sliding of the sliding frame 8 drives the detection component to rise and fall.

[0025] Reference Figure 1 The detection component includes a second motor 10 , the upper surface of the second motor 10 is arranged on the lower surface of the sliding frame 8 , and a detector 11 is fixedly provided at the output end of the second motor 10 .

[0026] Specifically, starting motor 2 10 can drive the detector 11 at the output end to rotate, and can detect at multiple angles. The detector 11 converts the received light signal into an electrical signal, and then amplifies, filters, linearizes, and processes the weak electrical signal output by the light detector so that it can be accurately identified and processed by the subsequent data acquisition and display unit, collects the electrical signal after signal processing, and converts it into a light brightness value that can be intuitively read.

[0027] Reference Figure 1 and Figure 3 A fixing column 12 is fixedly connected to the upper surface of the shell 2; a hydraulic cylinder 13 is fixedly connected to the interior of the shell 2, and a sleeve 14 is fixedly connected to the output end of the hydraulic cylinder 13.

[0028] Specifically, the fixed column 12 can support the sleeve 14 to slide, and the hydraulic cylinder 13 is started to drive the sleeve 14 at the output end to slide.

[0029] Reference Figure 1 and Figure 3 The outer wall of the sleeve 14 is rotatably connected to a rocker arm 15, and the middle outer wall of the rocker arm 15 is rotatably connected to a rotating shaft 16; the outer wall of the rotating shaft 16 is rotatably connected to a rocker arm 2 17, one end of the rocker arm 2 17 is rotatably connected to a rotating shaft 2 20, and the other end of the rocker arm 2 17 is rotatably connected to the lower outer wall of the rocker arm 15; the outer wall of the rotating shaft 2 20 is provided with a telescopic rod 18, and the outer wall of the telescopic rod 18 is provided at one end of the fixed column 12.

[0030] Specifically, each telescopic rod 18 is connected to three groups of sleeves 14 and rocker arm 1 15. The sleeve 14 is connected to the lower outer wall of rocker arm 1 15. The sliding of the sleeve 14 drives rocker arm 1 15 to rotate, and rocker arm 1 15 drives rocker arm 2 17 to rotate. The upper outer walls of rocker arm 1 15 and rocker arm 2 17 are both rotatably connected to the outer wall of rotating shaft 2 20. When rocker arm 1 15 and rocker arm 2 17 rotate, rotating shaft 2 20 closest to the fixed column 12 will slide on the outer wall of the telescopic rod 18, and rocker arm 1 15 and rocker arm 2 17 away from the fixed column 12 will drive the telescopic rod 18 to start telescoping.

[0031] Reference Figure 1 and Figure 3 The other end of the telescopic rod 18 is provided with a blackout cloth 19.

[0032] Specifically, the telescopic rod 18 can be extended or retracted to expand or retract the blackout cloth 19 to cope with the interference of strong light.

[0033] Working principle: When using the device, first place the object to be detected on the lower side of the detector 11, and start the motor 13 to drive the worm 4 at the output end to rotate, the worm 4 drives the worm wheel 5 to rotate, and the worm wheel 5 drives the transmission shaft 6 to rotate. One end of the transmission shaft 6 rotates inside the housing 2, and the other end of the transmission shaft 6 is connected to the connecting rod 1 7. The transmission shaft 6 drives the connecting rod 1 7 to rotate, and the connecting rod 1 7 drives the connecting rod 2 21 to rotate. The lower outer wall of the connecting rod 2 21 is pulled to the sliding frame 8 to slide, and the sliding frame 8 slides inside the limit frame 9. The sliding frame 8 drives the motor 2 10 and the detector 11 to rise and fall, and the distance between the detector 11 and the object to be detected can be adjusted. Then, by starting the motor 2 1 0 can drive the detector 11 to rotate and realize multi-angle detection of objects. When the detection is interfered by strong light, the sleeve 14 at the output end is driven to slide by starting the hydraulic cylinder 13, and the sleeve 14 pushes the rocker arm 15 to rotate. The rocker arm 15 drives the rocker arm 2 17 to rotate through the rotating shaft 20. At the same time, the rotating shaft 20 drives the telescopic rod 18 to start telescoping. One end of the telescopic rod 18 is fixed to the outer wall of the fixed column 12, and the other end of the telescopic rod 18 can drive the blackout cloth 19 to unfold to block the light. This device can not only adjust the distance between the detector 11 and the object to be detected and improve the accuracy of the detection, but also avoid the interference of strong light through the blackout cloth 19.
