A digital display screen 101 is provided on the outer surface of the housing 1. The detection device can be installed on a wall structure near the gas pipeline. This device adopts a wireless control method and can be wirelessly networked with the gas pipeline and ventilation equipment to realize joint control operation. When the device detects the presence of gas in the air, it triggers an alarm signal. Subsequently, the central control terminal will open the ventilation and the solenoid valves inside the pipeline to ensure the safety of the workshop.

[0022] One end of the sensing component 2 is provided with a gas collection port 201, which extends to the outside of the insulating bushing 102. The other end of the sensing component 2 is provided with a contact piece 203. A dust filter seal 202 is provided at one end of the gas collection port 201. The dust filter seal 202 is connected to the gas collection port 201 via a slot. The dust filter seal 202 needs to be disassembled and replaced after a period of use to avoid clogging. The sensing component 2 is internally provided with a processing module 204. Sleeves 205 are provided on both sides of the bottom of the processing module 204. An infrared transceiver component 206 is provided inside the sleeves 205. A connection is provided between the sleeves 205.

The sensing component 2 consists of two sets of sleeves 205 and a processing module 204. The air inside the workshop enters the air chamber 2051 between the sleeves 205 through the air collection port 201. The dust filter seal 202 at the front end of the air collection port 201 can work with the filter element to filter the suspended particles in the air, so as to prevent the particles from entering the air chamber 2051 with the air. The infrared transceiver components 206 distributed on both sides detect the air to determine whether there is a gas leak in the workshop environment.

[0023] The housing 1 houses a power module 106, and the bottom of the power module 106 has a hot-swappable interface 1061.

[0024] Working principle: The detection device can be installed on the wall structure near the gas pipeline. It uses wireless control, allowing it to wirelessly network with the gas pipeline and ventilation equipment for coordinated operation. Air from inside the workshop enters the air chamber 2051 between the sleeves 205 through the air collection port 201. The dust filter 202 at the front end of the air collection port 201, in conjunction with the filter element, filters suspended particles in the air, preventing them from entering the air chamber 2051 with the air. Infrared transceiver components 206 distributed on both sides detect the air. When the device detects the presence of gas in the air, it triggers an alarm signal. Subsequently, the central control unit opens the ventilation system and the solenoid valves inside the pipeline to ensure safety inside the workshop.
