The upper end of the storage tank body 1 is located outside the connecting pipe 2 and is fixedly connected with a fixed frame 3. The inner wall of the fixed frame 3 is surrounded by an annular slide groove 4. The inner wall of the annular slide groove 4 is rotatably connected with a rotating ring block 5. The outer side of the fixed frame 3 is fixedly connected with a motor 6 for driving the rotating ring block 5 to rotate along the annular slide groove 4. The power end of the motor 6 is fixedly connected with a turntable 7, and the outer wall of the turntable 7 and the outer wall of the rotating ring block 5 are evenly provided with mutually meshing latch teeth 8.

The motor 6 drives the turntable 7 at the power end to rotate, and uses the outer teeth 8 of the turntable 7 to engage with the teeth 8 on the inner wall of the rotating ring block 5, thereby driving the rotating ring block 5 to slide and rotate along the annular groove 4 on the inner wall of the fixed frame 3, so that the air detector 9 at the upper end of the rotating ring block 5 can be driven to perform air detection around the connection position of the connecting pipe 2 at the upper end of the tank body 1, and detect whether there is any gas leakage stored in the tank body 1. If there is a leakage, the air detector 9 starts the buzzer through the PLC controller to alarm, which is convenient for the staff to deal with it in time and avoid safety accidents.

[0025] It should be noted that the storage tank body 1 is used to store some chemical gases, and the air detector 9 can detect these stored gases.
