Description

Gas early warning detection device

Technical Field

The utility model relates to the field of gas early warning detection, in particular to a gas early warning detection device.

Background

At present, the great danger source early warning of gas is surveyed and is stayed local area scope control category, generally, show as installing gas detector additional to the danger source region, give the controller with signal transmission through gas detector response, the controller is reported to the police to siren control, realize alarming function, the fan that also can control great danger source department simultaneously and set up is sparse with the dangerous source gas of gathering, in order to guarantee the security of dangerous source gas, but current gas detector belongs to passive induction at the response, the air enters into gas detector and just can be responded to, cause very easily that great danger source has exceeded standard partially, but gas detector can't respond to fast, cause early warning detection lag, seriously influence the safety of danger source.

SUMMERY OF THE UTILITY MODEL

In order to solve the existing problems, the utility model provides a gas early warning detection device.

The utility model is realized by the following technical scheme:

the utility model provides a gaseous early warning detection device, includes gaseous alarm control ware and rather than blowing away fan, siren, gas detector through cable electric connection, gas detector is provided with the intake pipe by detector body and its bottom and constitutes, intake pipe lower part swivelling joint has the adsorption tube, the annular is opened on the adsorption tube has a plurality of air inlet, set up a plurality of filtration mesh holes in the just right intake pipe of air inlet, the inside lower extreme of adsorption tube is provided with adsorption apparatus and constructs.

Preferably, the adsorption mechanism is composed of a fan and a fixing frame which are opposite to the inlet of the air inlet pipe, the fan is fixed in the adsorption pipe through the fixing frame, and the bottom end of the adsorption pipe opposite to the fan is provided with an adsorption hole.

Preferably, the outer wall of the air inlet pipe is provided with a clamping groove, and the clamping groove is internally and rotatably connected with a clamping ring arranged on the inner wall of the adsorption pipe.

Preferably, the adsorption tube is made of stainless steel.

Compared with the prior art, the utility model has the beneficial effects that: this practicality is wider to the gaseous detection scope of major hazard, and can not have surveying the early warning in dead angle, and the accurate security that the early warning was surveyed is guaranteed to greatly reduced monitoring lag time.

Detailed Description

The utility model is described in further detail below with reference to the following detailed description and accompanying drawings:

as shown in fig. 1, fig. 2, fig. 3, a gaseous early warning detection device, including gaseous alarm control ware 1 and blow away fan 3, siren 4, gas detector 5 rather than through cable 2 electric connection, gas detector 5 is provided with intake pipe 7 by detector body 6 and bottom and constitutes, intake pipe 7 lower part swivelling joint has adsorption tube 11, the annular is opened on adsorption tube 11 has a plurality of air inlet 8, set up a plurality of filtration mesh 9 on the air inlet 8 just right intake pipe 7, the inside lower extreme of adsorption tube 11 is provided with adsorption apparatus.

The adsorption mechanism is composed of a fan 14 and a fixing frame 15, wherein the fan 14 is opposite to the inlet of the air inlet pipe 7, the fan 14 is fixed in the adsorption pipe 11 through the fixing frame 15, and the bottom end of the adsorption pipe 11, opposite to the fan 14, is provided with an adsorption hole 13.

The outer wall of the air inlet pipe 7 is provided with a clamping groove 10, and the clamping groove 10 is rotatably connected with a clamping ring 12 arranged on the inner wall of the adsorption pipe 11.

The adsorption tube 11 is made of stainless steel.

The working principle is as follows: when gas of a heavy hazard source is subjected to early warning detection, a plurality of gas detectors 5 arranged on the heavy hazard source detect that combustible gas can transmit signals exceeding a set value to the gas warning controller 1, the gas warning controller 1 controls the alarm 4 to perform early warning, and controls the blow-off fan 3 to diffuse so as to prevent the combustible gas from gathering, thereby ensuring the safety of the heavy hazard source;

when the gas detector 5 detects gas, the adsorption mechanism of the adsorption tube 11 of the gas detector 5 is in a normally open state, the started fan 14 blows air outside the adsorption hole 13 into the air inlet tube 7 and enters the detector body 6, meanwhile, the gas passing through the filter mesh 9 can generate negative pressure right around the air inlet 8, and the gas around the adsorption tube 11 is adsorbed, so that the gas detector 5 can detect the gas, the detection range of the gas detector is wider relative to that of a passive detector, detection and early warning can be performed without dead angles, the monitoring lag time is greatly reduced, and the safety of early warning detection is ensured;

because gas detector 5 locates outdoors, filter mesh 9 and block up very easily, can regularly rotatory adsorption tube 11, adsorption tube 11 passes through snap ring 12 and rotates in draw-in groove 10 of intake pipe 7, and air inlet 8 on the adsorption tube 11 rotates and just to unobstructed filter mesh 9 simultaneously to guarantee the stability of gas detector 5 operation.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed.
