By air induction hose, air-introduced machine introduce gas, original gas in whole device can be discharged first, then accumulate again expire to
Detect sample gas, in this way, can ensure that the components relevant to strile-bacing such as ingredient, the temperature of gas and dust to be detected in cabinet with
It closes in place unanimously, and then keeps testing result more acurrate, have more referential, middle direct sampling enters compared with the existing technology
For cabinet, early warning precision Gao Genggao.
(2) air-introduced machine is arranged in air inlet mouth of pipe the utility model (can be set up directly on air inlet adjustment valve air inlet hold-carrying
Orchid connection), it is that dust content is larger in the sample gas due to acquisition, air-introduced machine needs periodic cleaning, set on herein and passing through method
The mode of orchid connection connects, its disassembly can be made more convenient, cleaning is easier.
(3) incendiary source is arranged in the utility model in cabinet, can be by the unlatching of incendiary source, to sample air lift for fire source, i.e.,
The duration, temperature and cabinet pressure during strile-bacing that sample gas strile-backs when meeting fire source can be detected, these data can be to disappear
Anti- personnel's early warning carries out fire rescue after so that fire fighter is carried out sufficient prepare, it is ensured that the personal safety of fire fighter again.
(4) the utility model is also provided with source of oxygen, and oxygen is passed through into cabinet by source of oxygen, and detects that sample gas returns
Temperature when amount of oxygen, the sample gas being passed through needed for combustion strile-back and data, these data such as cabinet pressure are during strile-bacing
It can be fire fighter's early warning, carry out fire rescue again after so that fire fighter is carried out sufficient prepare, it is ensured that the people of fire fighter
Body safety.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in further detail with embodiment for explanation with reference to the accompanying drawing, and the mode of the utility model includes
But it is not limited only to following embodiment.
A kind of fire strile-backs and dust explosion prior-warning device, and referring to Fig. 1, which includes cabinet 1,51 single-chip microcontrollers and oxygen
