Through the above technical solutions, the comprehensive survey device provided by the utility model for fire is inhaled by reasonable Arrangement
Feed channel and selection feature sensor 21 avoid existing so that the detection detection to fire is not limited by space-time, environment and combustible
There are the complicated procedures of installation, the wiring of detection device, reduce wrong report and fail to report, realizes the early detection and online prison in real time of fire
It surveys, reaches and improve fire detection accuracy and efficiency effect, reduce the generation and loss of fire.It is provided by the utility model comprehensive
Close sampling unit 10, purging displacement unit 50, the analytical unit 20, online monitoring alarm system 30, control master in detection device
Machine 40, which is integrated into three-dimensional cabinet, carries out centralized control, carries out fire inspection to scene under the premise of not influencing produced on-site
Survey, further improve fire detection device operation simplicity and maintenance it is quick.Simultaneously but also detection device it is reliable
Property greatly improve, can effective guarantee equipment and personnel safety.
The optional embodiment of the utility model is described in detail in conjunction with attached drawing above, still, the utility model is simultaneously unlimited
Detail in above-mentioned optional embodiment can be to the utility model in the range of the technology design of the utility model
Technical solution carry out a variety of simple variants, these simple variants belong to the protection scope of the utility model.
It is further to note that specific technical features described in the above specific embodiments, in not lance
In the case where shield, it can be combined in any appropriate way.In order to avoid unnecessary repetition, the utility model is implemented
No further explanation will be given to various combinations of possible ways for mode.
In addition, any combination can also be carried out between a variety of different embodiments of the utility model, as long as it is not disobeyed
