The four visual detection mechanisms 2 are circumferentially located around the pressure sealing hoop 100 of the gas meter to be detected; the pressure sealing hoop 100 of the gas meter to be detected is visually detected by the four circumferentially arranged visual detection mechanisms 2. The multiple visual detection mechanisms 2 intersect with each other to perform 360° visual detection on the pressure sealing hoop 100, and detect the periphery of the pressure sealing hoop of the ultrasonic gas meter without manual intervention; and the detection is carried out in a full-coverage manner, greatly improving the detection accuracy.

[0052] Reinforcing ribs 25 are symmetrically arranged at the connection between the upper fixing plate 24 and the reinforcing rib connecting plate 23, and the length of the reinforcing ribs 25 is greater than the height of the reinforcing rib connecting plate 23; the connection strength between the upper fixing plate 24 and the reinforcing rib connecting plate 23 is improved, thereby ensuring the use safety.

[0058] Specifically, the installed shadowless ring light source 36 and the industrial camera 34 cooperate with each other. To prevent the light from hurting the operator's eyes when it is in the on state, the shadowless ring light source 36 is set directly below the industrial camera 34, and the industrial camera 34 is assembled in the middle of the shadowless ring light source 36. In this way, the light emitted by the shadowless ring light source 36 can only be directed towards the surface of the sealing hoop 100 of the gas meter to be detected for fill light operation during photographing.
