Description
Technical field
The utility model is a kind of dust determination device of portable multifunctional, belongs to Mine Dust monitoring field.
Background technology
In the behind of coal in China Industry Quick Development, there is it is many problem of, produced during coal mining
Substantial amounts of dust.Mine Dust is the general name of colliery caused all kinds of solid matter fine particles in process of production.Dust meeting
Enter human body respiration organ with the breathing of people, be easy to be excreted wherein larger grit is delayed in respiratory tract, and grain
Dust big portion of the footpath less than 5 microns can enter human lung and trigger all kinds of pneumoconiosis, and long-term excessive suction dust can cause
Pneumoconiosis, human body is caused greatly to endanger.In addition also there is the danger of blast in dust, and to enterprise and worker, all there is huge
Big threat.
But this harm is covered by the prosperity and development of coal all the time, Mine Dust does not cause enough weights
Depending on the guarantee to coal miner health is extremely urgent, and existing device does not take into full account situation complicated under ore deposit yet.
The content of the invention
The purpose of this utility model is：A kind of mining dust concentration measuring device is provided, to solve dust in existing ore deposit
Concentration is not easy to monitor, and seriously endangers personnel health under ore deposit, the problem of very big potential safety hazard be present.
To solve the above problems, intending using such a mining dust concentration measuring device, including cabinet, set in cabinet
There is gas passage, the both ends for crossing gas passage extend out to the outside of cabinet and form air inlet and gas outlet respectively, cross on gas passage
Aspiration pump and spherical sampling camera bellows are additionally provided with, both sides relative in camera bellows is sampled and is correspondingly arranged on light source emitter and light source
Receiver, light source emitter and light source receiver are connected with OSP, and OSP is also associated with voice message
Device.
In foregoing measure device, air inlet, sampling camera bellows, aspiration pump and gas outlet may be contained within the axis of gas passage
On；
In foregoing measure device, aspiration pump, sampling camera bellows and OSP may be contained within cabinet, voice message dress
Install and be placed on the outer wall of cabinet；
In foregoing measure device, explosion-proof electrical source is additionally provided with cabinet, is connect respectively with aspiration pump, light source emitter, light source
Receive device with OSP to be connected, be system power supply；
In foregoing measure device, be additionally provided with flashlight on the cabinet outer wall on the downside of air inlet, flashlight also with anti-explosion electric
Source is connected；
In foregoing measure device, sample and at least two light source emitters and two light sources receptions are correspondingly arranged in camera bellows
Device, and light source emitter and light source receiver are correspondingly arranged on controlling switch, specially set and are respectively used to control light source transmitting
The start button and end key for the sampling camera bellows that device and light source receiver open and close.
Compared with prior art, the utility model is simple in construction, easy to operate, being capable of fast and effeciently mensuration region dust
Concentration, once excessive concentration, can remind personnel under ore deposit to take dust suppression in time, ensure safety and personnel health under ore deposit；Adopt
Sample camera bellows is spherical camera bellows, reduces the volume of device, easy to carry；Dust sampling camera bellows has at least twice light source, passes through meter
Average value is calculated, improves the degree of accuracy of detection, the start button of camera bellows is sampled and end key is applied to point that measurement different time needs
Into concentration；With sound prompt device, the result of OSP can be received, is reported in the form of speech, convenient record；Increase
Standby flashlight is added, to avoid light source caused by the emergency situations of underground from dissipating, so as to avoid bigger accident.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
To make the utility model relatively sharp clearly, the utility model is described further below in conjunction with accompanying drawing.
Embodiment：
Referring to the drawings 1, the present embodiment provides a kind of mining dust concentration measuring device, including cabinet 1, is set in cabinet 1
There is gas passage 2, the both ends for crossing gas passage 2 extend out to the outside of cabinet 1 and form air inlet 21 and gas outlet 22 respectively, cross gas
Aspiration pump 3 and spherical sampling camera bellows 4, air inlet 21, sampling camera bellows 4, aspiration pump 3 and gas outlet 22 are additionally provided with passage 2
On the axis that may be contained within gas passage 2, relative both sides are correspondingly arranged on light source emitter 5 in sampling camera bellows 4 and light source connects
Device 6 is received, and light source emitter 5 and light source receiver 6 respectively have two groups, light source emitter 5 and light source receiver 6 are connected with optical signal
Processor 7, OSP 7 are also associated with sound prompt device 8, the aspiration pump 3, sampling camera bellows 4 and optical signal prosessing
Device 7 be may be contained within cabinet 1, and sound prompt device 8 is arranged on the outer wall of cabinet 1, and explosion-proof electrical source 9 is additionally provided with cabinet 1,
It is connected respectively with aspiration pump 3, light source emitter 5, light source receiver 6 and OSP 7, is system power supply, air inlet 21
Flashlight 10 is additionally provided with the outer wall of cabinet 1 of downside, flashlight 10 is also connected with explosion-proof electrical source 9；
In use, the switch of explosion-proof electrical source 9 is opened, aspiration pump 3 is opened, and air enters sampling camera bellows 4 from air inlet 21, so
