Description
Technical field
This utility model relates to gas monitor field, is specifically related to a kind of distributed underground pipe network gas monitoring apparatus.
Background technology
In recent years, Urban Buried Pipeline Network gas burst or personnel's intoxication accident happen occasionally, and main cause is underground pipe network
Humid environment, relative closure, waste water, blowdown thing decompose the most inflammable and explosive, toxic and harmful such as CH4, H2S, CO etc., this kind of
Accumulated gases is in the space of underground pipe network, if can not find in time to dispose, once concentration over-standard, it is possible to occur various
Accident, brings massive losses to the people's lives and property.
At present, the monitoring mode of underground pipe network gas is mainly manual inspection, carries out harmful gas according to patrolling and examining result
Pump drainage.The mode using manual inspection is monitored, and on the one hand patrol officer works heavy, on the other hand can not click on monitoring
Row monitoring in real time, it is impossible to find in time and remove a hidden danger, it is to avoid the generation of accident, and detection efficiency is low.For solving this
Problem, part manufacturer or scientific research institutions are also proposed some gas monitoring apparatus, but traditional supervising device can only be to gas
Body is monitored, it is impossible to finds in time and removes a hidden danger；Further, on market, existing gas monitoring apparatus is within the specific limits
Each site is spot-check, and numerous owing to layouting, cause the relatively costly of gas monitor.
Utility model content
The purpose of this utility model is the deficiency in order to overcome above-mentioned background technology, it is provided that a kind of distributed underground pipe network gas
Body supervising device, it is adaptable to the detection of gas concentration and monitoring in various underground pipe networks, the monitoring range of this supervising device is wide, energy
Enough monitoring from a point expand to the monitoring in a face, the most cost-effective, and reasonable distribution resource.
This utility model provides a kind of distributed underground pipe network gas monitoring apparatus, including exhaust tube, air pump, aerofluxus
Pipe, gas detection sensor, exhaust tube, exhaustor be connected with air pump respectively, and air pump is connected with gas detection sensor, this
Supervising device also includes that exhaust tube collector, electromagnetic relay, the side of exhaust tube collector have several pipe interfaces, one
The corresponding exhaust tube of individual pipe interface, some exhaust tubes are connected with exhaust tube collector by pipe interface, exhaust tube collection
The opposite side of clutch is connected with air pump, and the inside of exhaust tube collector connects with air pump；Every exhaust tube is provided with valve
Door, valve, air pump, gas detection sensor are connected with electromagnetic relay respectively.
Pipe interface quantity≤32 on the basis of technique scheme, in described exhaust tube collector.
On the basis of technique scheme, described valve is positioned at the inside of exhaust tube collector.
Compared with prior art, advantage of the present utility model is as follows:
(1) this utility model is controlled bleed detection and the exhaust work of exhaust tube, air pump by electromagnetic relay, can be right
Monitoring point is monitored in real time, is conducive to finding in time and removing a hidden danger, it is to avoid the generation of accident, and detection efficiency is high.
(2), on market in existing gas monitoring apparatus, air pump, exhaustor and gas detection sensor can only be corresponding
The site of one underground pipe network, namely a corresponding exhaust tube, although current monitor site can be monitored, but from
Layout for distributing, it is impossible to ensure distribution equilibrium, if it is numerous to layout, the cost of gas monitor can be caused gas monitoring apparatus
Higher, therefore use existing gas monitoring apparatus, can only within the specific limits underground gas be spot-check.This utility model
Using exhaust tube collector, this supervising device can monitor most 32 sites simultaneously；By electromagnetic relay, exhaust tube is carried out
Control, it is achieved 32 points are bled detection and exhaust work.Simple in construction, monitoring range is wide, expands from the monitoring of a point
Open up the monitoring in a face, the most cost-effective, and reasonable distribution resource.This supervising device a set of the most at most can be supported
32 inspection shafts.

Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is described in further detail by specific embodiment.
Shown in Figure 1, this utility model embodiment provides a kind of distributed underground pipe network gas monitoring apparatus, including taking out
Trachea 1, air pump 4, exhaustor 5, gas detection sensor 6, exhaust tube 1, exhaustor 5 be connected with air pump 4 respectively, air pump
4 are connected with gas detection sensor 6, and this supervising device also includes exhaust tube collector 2, electromagnetic relay 3, shown in Figure 2,
The side of exhaust tube collector 2 has several pipe interfaces 2a, pipe interface 2a quantity≤32, pipe interface 2a pair
Ying Yigen exhaust tube 1, some exhaust tubes 1 are connected with exhaust tube collector 2 by pipe interface 2a, exhaust tube collector 2
Opposite side is connected with air pump 4, and the inside of exhaust tube collector 2 connects with air pump 4；Shown in Figure 3, every exhaust tube 1
