Description
Technical field
This utility model relates to technical field of coal mining protection facilities, particularly relates to a kind of novel dust concentration sensing device.
Background technology
The operation principle of dust sensor is developed according to scattering of light principle, and microgranule and molecule are under the irradiation of light
Scattering of light phenomenon can be produced, meanwhile, also absorb the energy of partial illumination light.When a branch of collimated monochromatic ligth incides tested
During particle field, can be affected by scattering around granule and absorbing, light good general be attenuated.The most just can try to achieve incident illumination to lead to
Cross the relative attenuation rate of concentration field to be measured.And the size of relative attenuation rate substantially can linear response field to be measured dust the denseest
Degree.The size of light intensity and being directly proportional through the signal of telecommunication power of opto-electronic conversion, just can be in the hope of relative attenuation by recording the signal of telecommunication
Rate, and then just can measure the concentration of dust in field to be measured.Owing to monitoring pipe is in dust laden air, of long duration can be in monitoring
Adsorbing some dusts on pipe, if not removing these dusts, monitoring pipe can be mistakenly considered the dust in air, impact monitoring essence
Degree, and in the conditions and environment of underground coal mine, it is impossible to cleaning dust monitoring pipe.
Utility model content
This utility model purpose is, in place of overcoming the deficiencies in the prior art, it is provided that a kind of Novel powder dust concentration sensing dress
Putting, when can keep monitoring dust, the cleaning of monitoring pipe, improves accuracy and the precision of monitoring result, it is ensured that underground work
Safety is carried out.
The novel dust concentration sensing device of one described in the utility model, includes casing, is arranged on casing internal
Monitoring is managed, is arranged on the light supply apparatus of monitoring pipe side, is arranged on the lens above monitoring pipe and is arranged on above lens
Detection device, it is characterised in that between monitoring pipe and lens, is close to monitor pipe and is provided with zona pellucida, described zona pellucida two ends
It is wound in the rotating shaft arranged in casing internal both sides, in rotating shaft, the two ends of zona pellucida winding position, it is provided with block, institute
State block zona pellucida to be kept straightly to be wrapped in rotating shaft be unlikely to twining partially, in two rotating shafts at least the one of at least one rotating shaft
End extend out to outside casing, and is connected with knob at rotating shaft external part, can drive axis of rotation by turn knobs, thus
Change the zona pellucida after using.When in use, one end time turn knobs can be spaced, drive axis of rotation, make zona pellucida
The dust of the upper attachment of erasing monitoring pipe, consequently facilitating monitoring dust data.
The novel dust concentration sensing device of one described in the utility model, overall structure is simple, easy for operation, surely
Qualitative good, reliability is high, uses the novel dust concentration sensing device of one described in the utility model, when can keep monitoring dust
The cleaning of monitoring pipe, improves accuracy and the precision of monitoring result, it is ensured that the safety of underground work is carried out.
Accompanying drawing explanation
Accompanying drawing 1 is the internal structure schematic diagram of a kind of novel dust concentration sensing device described in the utility model.Accompanying drawing 2
It it is the inside top structural representation of a kind of novel dust concentration sensing device described in the utility model.
Detection device 3-lens 4-monitoring pipe 5-light supply apparatus 6-rotating shaft 7-is saturating for 1-casing 2-
Oolemma 8-block 9-knob.
Detailed description of the invention
Referring now to accompanying drawing 1 and accompanying drawing 2, it is described in conjunction with the embodiments as follows: the novel dust of one described in the utility model is dense
Degree sensing device, include casing 1, be arranged on casing 1 within monitoring pipe 4, be arranged on monitor pipe 4 side light supply apparatus 5,
It is arranged on the lens 3 above monitoring pipe 4 and is arranged on the detection device 2 above lens 3, it is characterised in that monitoring pipe 4 He
Between lens 3, being close to monitor pipe 4 and be provided with zona pellucida 7, described zona pellucida 7 two ends are wound in casing 1 internal both sides setting
In rotating shaft 6, in rotating shaft 6, the two ends of zona pellucida 7 winding position, it is provided with block 8, described block 8 can keep zona pellucida 7 straight
Directly being wrapped in rotating shaft 6 and be unlikely to twine partially, in two rotating shafts 6, at least one end of at least one rotating shaft 6 extend out to outside casing 1
Portion, and it is connected with knob 9 at rotating shaft 6 external part, rotating shaft 6 can be driven to rotate by turn knobs 9, thus after changing use
Zona pellucida 7.Rotating shaft 6 mentioned here can also all extend out to casing 1 outside in two ends.When in use, one end can be spaced
Time turn knobs 9, drives rotating shaft 6 to rotate, and makes the dust of attachment on zona pellucida 7 erasing monitoring pipe 4, consequently facilitating monitoring dust
Data.The novel dust concentration sensing device of one described in the utility model, overall structure is simple, easy for operation, stable
Property good, reliability is high, uses the novel dust concentration sensing device of one described in the utility model, prison when can keep monitoring dust
The cleaning of test tube, improves accuracy and the precision of monitoring result, it is ensured that the safety of underground work is carried out.
