Description

Technical Field

[0001] The utility model relates to the technical field of smoke exhaust systems, in particular to an organic matter concentration detection probe component for exhaust equipment. Background Art

[0002] At present, the fire protection ventilation requirements for underground spaces are becoming more and more stringent. For example, large spaces such as underground garages and warehouses need to have higher ventilation requirements to ensure the normal circulation of air and that the smoke exhaust system can effectively discharge harmful gases from underground spaces in the event of safety hazards such as fires, and the equipment adopts a longitudinal layout.

[0003] Application number: CN202223368893.4, "A device for detecting and exhausting polluted gas concentration in an underground parking lot". When using the device for detecting and exhausting polluted gas concentration in an underground parking lot, the device is first hoisted on the truss on the top of the basement, and the box shell is fixed to the outer frame to form a box body. The triangular bracket is elastically connected to the pull rod through a shock absorber, and the entire air duct is installed on four pull rods, which can effectively absorb the vibration generated by the operation of the motor in the air duct. The air duct is interconnected with the exhaust port through an exhaust hose, and the air duct is interconnected with the air supply port through an air supply hose. Multiple carbon monoxide detectors can be installed in multiple areas of the basement. When a vehicle passes through the basement, the carbon monoxide detector will detect the concentration of carbon monoxide emitted from the exhaust gas of the vehicle in real time. If the concentration exceeds the standard, the controller controls the motor to start, and the motor drives the blades to work to ensure that the air in the tunnel remains fresh and ventilated. After the concentration of carbon monoxide returns to normal, the motor is stopped to achieve energy-saving effects.

[0004] However, the carbon monoxide detector and controller in the exhaust device for detecting the concentration of polluted gas are not easy to disassemble and remove, which makes the gas concentration detection equipment very inconvenient during maintenance and inspection. Utility Model Content
