Description
The utility model relates to air sampling rig under the coal mine, and concrete is a kind of coal mine environment gas automatic sampling device.
Contain toxic and harmfuls such as methane, carbon monoxide, carbon dioxide in the underground air of colliery, measure these toxic and harmfuls, need arrive and gather air sample under the coal mine, deliver to again and allow gas analysis instrument analyze definite value on the ground for qualitative, quantitative ground.
At present, the production operation place is gathered the classic method of air sample and is under the coal mine: the sample collector inflates in bladders with the air-breathing ball of hand pinching at the scene, and bladders is full of behind the gas quilt and is tightened and be carried on the ground.This sampling method exists following shortcoming;
1. be full of a bladders gas, hand wants pinching more than 20 times, spends 5 fens clock times, and is more tiring time-consuming, and the hand channel of especially pinching balloon is often tired as to ache;
Since sample collector's health near the sampling environment, personnel walk about and factor such as breathing causes that to be gathered air sample untrue;
3. because people's arm is shorter, some place, as the inbreak space, the air sample in the goaf is airtight be difficult for gathering in addition gather less than.
4. dangerous: the air sampling district generally is the area that is suspect to be gas accumulation, and the sample man closely gathers air sample in the gas accumulation district, easily go out danger, inadequately safety.
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of coal mine environment gas automatic sampling device is provided, and can collect air sample far away, higher position, and sample is true, processing ease, laborsaving, save time, safety, volume is small and exquisite, easy to carry.
The purpose of this utility model is achieved in that
A kind of coal mine environment gas automatic sampling device comprises sampling draft tube and inflation bladders, it is characterized in that:
The sampling draft tube is connected in a flexible pipe that certain-length arranged, this flexible pipe is held the inlet tube joint that is connected in a reciprocating type film air pump in addition, the gas outlet of this film air pump connects the induction pipe of inflating bladders with pipe adapter, and this inflation bladders induction pipe is provided with the pipe clamp of sealing disassembly fast;
One miniature cocurrent electromotor is driven by direct supply, and the output shaft of this motor is articulated in eccentric wheel and drives the reciprocating connecting rod of film air pump, and described film air pump, direct current generator and gear train thereof, direct supply all are contained in the rectangle box body;
Described sampling draft tube is connected in a hand-held stock.
The purpose of this utility model can also realize by following measure:
Inlet in described sampling draft tube is equipped with one 60 purpose screen packs, at the air intake opening of film air pump one 120 purpose screen packs is housed.
The sampling draft tube is connected in hand-held stock with hook.
The described hand-held stock that is connected in the sampling draft tube is telescopic structure.
The power supply of described DC micromotor is the ni-cd rechargeable battery group.
The utility model has following actively useful effect:
1. choosing the sampling draft tube with hand-held stock and taking a sample, can extend the place that can not reach, inbreak space for example, airtight goaf, La Ga zone, corner far beyond height and human body arm.
2. sampling place distance samples personnel's health is far away, and air is not subjected to factor affecting such as human body respiration, and sampling is relatively truer, accurate.
3. with the manual sampling in motor-driven replacement past, save time, laborsaving, efficient.
4. the sample man is far away apart from being suspect to be watt sampling spot of phase accumulation area, and is safer during operation.
5. in light weight, volume is little, easy to carry; This sampler can be made volume length * wide * height and be about 120 * 60 * 70 (mm of unit), can hang between waist on the belt, and sample man's waist is a sampling thief, and hand-held stock is easy to operate.
Now in conjunction with the accompanying drawings with preferred embodiment:
Fig. 1 is a construction profile synoptic diagram of the present utility model;
Fig. 2 is a structure principle chart of the present utility model.
Coal mine environment gas automatic sampling device of the present utility model comprises sampling draft tube 1 and inflation bladders 2, and structure please refer to Fig. 1 Fig. 2;
The sampling draft tube is connected in a flexible pipe 3 that certain-length arranged, this flexible pipe is held the inlet tube joint 5 that is connected in a reciprocating type film air pump 4 in addition, the gas outlet of this film air pump connects the induction pipe 7 of inflating bladders with pipe adapter 6, and this inflation bladders induction pipe is provided with the pipe clamp 8 of sealing disassembly fast; This pipe clamp 8 can use in the prior art the movable clip on the medical infusion lines for example.
One miniature cocurrent electromotor 9 is driven by direct supply 10, this direct supply can use chargeable battery, the output shaft of this motor 9 is articulated in eccentric wheel 11 and drives film air pump 4 reciprocating connecting rods 12, and described film air pump 4, direct current generator 9 and gear train thereof, direct supply 10 all are contained in the rectangle box body 13;
Described sampling draft tube is connected in a hand-held stock 14, and this hand-held stock can be ad hoc parts, also can be rod, the bamboo bar of taking conveniently at the scene.
