Description
Technical field
The present invention relates to underground coal mine monitoring sensor guard, specially colliery sensor guard.
The protector is used to prevent destruction of the shock wave to sensor caused by fire damp and coal-dust explosion.
Background technology
Underground coal mine is mounted with many sensors, including gas concentration sensor, air velocity transducer, carbonomonoxide concentration
Sensor, temperature sensor and Dust Concentration sensor etc., these sensors can be underground coal mine ring under normal circumstances
The monitoring in border provides foundation, but when accident occurs（Such as gas and coal-dust explosion）It can be destroyed and be failed.
Protection for sensor is faced with a puzzlement all the time, any safeguard procedures is not used, although can protect
The normal display of sensor display and the normal monitoring of sensor probe are demonstrate,proved, but gas or coal-dust explosion generation can not be resisted
Shock wave destroy；And after using closed protective, destroyed although shock wave caused by gas or coal-dust explosion can be resisted,
The normal display of sensor display in use and the normal monitoring of sensor probe can not be ensured.
The content of the invention
Normal display, monitoring and blast protection the shock wave destruction that the present invention solves existing underground coal mine sensor can not be reasonable
A kind of the problem of taking into account, there is provided colliery sensor guard.The device can ensure that sensor is shown in normal circumstances
The normal display of device and the normal monitoring of sensor probe, blast production can be effectively resisted when gas or coal-dust explosion occurs
The destruction of raw shock wave, and recover after shock wave normal display, the monitoring of sensor at once.
The present invention adopts the following technical scheme that realization：Colliery sensor guard, including in rectangular-shape
Protecting crust, and the outer protecting crust for the rectangular-shape being placed on outside interior protecting crust, shape is had on the lower opposite face of inside and outside protecting crust
Shape, size identical sensor display window and sensing window, are respectively fixed between the left and right opposite face of inside and outside protecting crust
Spring（The both ends of spring are fixed with the left and right opposite face of inside and outside protecting crust respectively）, the left and right opposite face of inside and outside protecting crust it
Between spring do not stress state（Free state）Under, the display window on the lower opposite face of inside and outside protecting crust is alignd, induction window
Mouth alignment；The top surface of outer protecting crust is provided with the stroke bar hole along outer protecting crust length direction, the top surface of interior protecting crust be fixed with from
The dop that stroke bar hole on outer protecting crust passes.In use, sensor is placed in interior protecting crust and makes its display screen（Window）, sense
Answer position（Part）It is aligned respectively with display window, sensing window, the dop of interior protecting crust top surface is fixed on coal mine down-hole tunnel top
Plate.Under normal condition, the spring between the inside and outside left and right opposite face of protecting crust does not all stress and under inside and outside protecting crust on opposite face
Display window and sensing window alignment, now, sensor can normally show, normally monitor；Gas or coal-dust explosion is occurring
When, by exploding, caused shock wave is acted on, and length direction of the outer protecting crust along its stroke bar hole is the length side of outer protecting crust
To by a lateral opposite side movement（In moving process, dop slides along stroke bar hole, does not interfere with the movement of outer protecting crust）,
Display window under inside and outside protecting crust on opposite face and sensing window are staggeredly located, i.e., outer protecting crust is by the display of interior protecting crust
Window and sensing window block, and are protected the sensor in interior protecting crust；Meanwhile the inside and outside left and right opposite face of protecting crust it
Between spring side tension, opposite side be pressurized；After shock wave, under the action of the spring, outer protecting crust is resetted, so as to recover
The normal display of sensor, normal monitoring.
Further, for prevent inside and outside protecting crust with respect in sliding process because spring contraction is asynchronous cause inside and outside prevent
Sliding friction increase between protective case and influence to slide, be fixed with interior protecting crust, between the inwall of left and right with interior protecting crust or so
The vertical chute of inwall, the pull draw runner vertical with outer protecting crust or so inwall is fixed with the left and right inwall of outer protecting crust, is taken out
Draw draw runner to be each passed through the left and right face of interior protecting crust to be engaged with the chute in it, so as to realize the slip of outer protecting crust（Move
It is dynamic）It is oriented to, slip is synchronously carried out.
Device of the present invention can ensure that the normal display of sensor display and sensor are visited in normal circumstances
The normal monitoring of head, gas is occurring or the destruction of shock wave caused by blast can be effectively resisted during coal-dust explosion, and
Shock wave recovers normal display, the monitoring of sensor at once later, its smart structural design, uniqueness, solves colliery well
Normal display, monitoring and the blast protection shock wave of downhole sensor are destroyed the problem of can not rationally taking into account, and are underground coal mine sensings
The preferable auxiliary products of device.
