After the electric cylinder 32 is started, it can drive the gas detector 1 fixed by the gasket 33 and its piston rod to move. When the gas detector 1 moves to a suitable height position, the electric cylinder 32 is turned off and the gas detector 1 is started through the external PLC. After the gas detector 1 is started, the toxic gas can be detected at that position. When the gas detector 1 detects the presence of toxic gas at that position, the gas detector 1 transmits a signal to the external PLC, and the external PLC controls and starts the alarm body 412, thereby reminding the staff.
