Description
Technical field
The present invention 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, a lot, the generation during coal mining is there is
Substantial amounts of dust.Mine Dust is the general name of all kinds of solid matter fine particles that colliery produces in process of production.Dust meeting
Breathing with people enters human body respiration organ, wherein larger grit is delayed in respiratory tract to be easy to be excreted, 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 be caused
Pneumoconiosis, greatly harm is caused to human body.In addition also there is the danger of blast in dust, enterprise and worker be existed 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 the situation of complexity under ore deposit yet.
The content of the invention
It is an object of the invention to：A kind of mining dust concentration measuring device is provided, to solve dust concentration in existing ore deposit
Monitoring is difficult, personnel health under serious harm ore deposit has very big potential safety hazard.
To solve the above problems, intend using the mining dust concentration measuring device of such a, including cabinet, set in cabinet
There is gas passage, the two ends for crossing gas passage extend out to the outside of cabinet and form air inlet and gas outlet respectively, crossed on gas passage
Aspiration pump and spherical sampling camera bellows are additionally provided with, relative both sides are correspondingly arranged on light source emitter and light source in sampling camera bellows
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 with aspiration pump, light source emitter, light source respectively
Receive device to be connected with OSP, 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, at least two light source emitters are correspondingly arranged in sampling camera bellows and two light sources are received
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 of the sampling camera bellows that device and light source receiver are opened and closed.
Compared with prior art, simple structure of the present invention, easy to operate, can fast and effeciently mensuration region dust it is dense
Degree, once excessive concentration, personnel take dust suppression in time under can reminding ore deposit, ensure safety and personnel health under ore deposit；Sampling
Camera bellows is spherical camera bellows, reduces the volume of device, easy to carry；Dust sampling camera bellows has at least twice light source, by calculating
Average value, improves the degree of accuracy of detection, and the start button and end key of camera bellows of sampling are suitable for being divided into that measurement different time needs
Concentration；With sound prompt device, the result of OSP can be received, reported in the form of speech, convenient record；Increase
Standby flashlight, is dissipated, with light source caused by the emergency situations for avoiding underground so as to avoid bigger accident.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Specific embodiment
To make the present invention relatively sharp clearly, below in conjunction with accompanying drawing, the present invention will be further described.
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 two ends for crossing gas passage 2 extend out to the outside of cabinet 1 and form air inlet 21 and gas outlet 22 respectively, crossed 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
May be contained within the axis of gas passage 2, relative both sides are correspondingly arranged on light source emitter 5 and light source connects in sampling camera bellows 4
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 is 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,
