Sampling device used for fire detection alarm

Abstract

The invention provides a sampling device capable of realizing comprehensive and accurate acquisition of indoor fire information. The sampling device comprises sampling pipes and sampling holes; the sampling holes are arranged on the sampling pipes; a detector is arranged at the ends of the sampling pipes; and the sampling pipes are arranged below a ceiling. According to embodiment I, the sampling pipes comprise a horizontal sampling pipe and a vertical sampling pipe, and both the horizontal sampling pipe and the vertical sampling pipe are provided with the sampling holes; the horizontal sampling pipe is arranged below the ceiling; the vertical sampling pipe and the horizontal sampling pipe are communicated; the end of the vertical sampling pipe is provided with the detector. According to embodiment II, the sampling pipes comprise a part parallel to the ceiling, and a part parallel to movable floor; the part parallel to the ceiling is arranged below the ceiling, the part parallel to the movable floor is arranged below the movable floor, and the two parts are communicated with a connection pipe; the end of the connection pipe is provided with the detector. Preferably, one end of the horizontal sampling pipe that is not communicated with the vertical sampling pipe is sealed.

Description

technical field [0001] The invention relates to the field of fire fighting, in particular to a fire detection system. Background technique [0002] For refineries, drilling platforms, compressor stations, fuel supply stations, chemical plants, liquefied gas storage device areas and other places, fire prevention is very important; as long as a fire occurs, it is likely to cause great danger to the entire production area; Therefore, the fire detectors used in these places are very important; the detectors are generally connected to the detection pipelines distributed in the room. The existing detection pipelines are generally composed of detection holes installed on the roof, and the sampling information is not comprehensive. It is easy to cause false positives and false positives. Contents of the invention [0003] The present invention aims at the deficiencies in the above-mentioned prior art, and provides a sampling device capable of comprehensively and accurately sampli...
