[0031] In use, first, the look-out balcony and the device are placed in a low-brightness environment, the fixed plate 1 is clamped on the side of the light source of the look-out balcony, then the threaded bolt 4 is rotated to move the threaded bolt 4 due to the threaded connection with the fixed plate 1, the threaded bolt 4 pushes the rubber sheet 5 to move, finally the rubber sheet 5 and the rubber pad 3 are fixed on the side of the light source of the look-out balcony, so that the fixed plate 1 and the look-out balcony remain relatively stable, and the light-shielding piece 703 is in contact with the surface of the light source of the look-out balcony at this time.

[0032] Then, the motor 602 is started after the detection mechanism 9 is stabilized, the motor 602 drives the driven wheel 604 to rotate through the transmission wheel 603, and then the driven wheel 604 drives the rotating rod 605 and the counterweight block 606 to rotate rapidly, and since the counterweight block 606 is a homogeneous circle, the center of gravity is stable during rapid rotation.

[0036] When the connecting rod 8 moves up and down, the counterweight block 606 rotates quickly, and due to the conservation of angular momentum, the angle of the photometric detector 905 will not be inclined due to slight external force during the movement, ensuring the stability of the movement;

[0037] And open the fan 702 while moving, so that the fan 702 quickly discharges the airflow through the air pipe 704 to the space between the light shield 703 and the light source, so that the airflow quickly discharges through the light shield 703 and the surface of the light source, forming an airflow pad, preventing the light shield 703 from contacting the light source and causing the photometric detector 905 to tilt; and the airflow carries away the impurities affecting the reading of the light source, preventing the pollutants from causing reading errors.
