Abstract
The invention discloses a mining passive pyroelectric infrared sensor which comprises a sensor shell, wherein, a sensor probe is arranged at the right end of the sensor shell; an aviation plug which is electrically connected with the sensor probe is arranged at the left end of the sensor shell; a bulb universal joint is arranged at the bottom of the sensor shell; a bulb positioned under the bulb universal joint is arranged in a spherical cavity which is formed by matching a bulb upper locking ring with a bulb lower locking ring, and a locking spacing is reserved between the upper locking ring and the lower locking ring; the bulb upper locking ring and the bulb lower locking ring are arranged in a cavity formed by matching an upper locking nut with a lower locking seat; the center of the top of the upper locking nut is equipped with an adjusting and limiting hole with a big upper end and a small lower end; and the upper part of the bulb universal joint penetrates the adjusting and limiting hole to connect with the bottom of the sensor shell. When in use, the orientation of the sensor probe can be adjusted by the bulb universal joint as required without moving location for reinstallation, thus the mining passive pyroelectric infrared sensor of the invention can be conveniently used.
Description
Technical field
The present invention relates to a kind of sensor, relate in particular to the passive pyroelectric infrared sensor on a kind of mining automatic control dust suppression device by water spray.
Background technology
Mining automatic control dust suppression device by water spray is mainly used in main haulage roadway under the coal mine, the main big lane of air entering and returning and getting working face air entering and returning lane, parking lot, coal bunker and other operation place that needs regularly atomizing de-dusting or regularly sprinkle water.Through auto spraying or watering, not only depositing dust dedusting, purify air, can absorb certain harmful gas simultaneously, reduce methane concentration and environment temperature, improve and improvement dust work environment, prevent and treat dust harzard.Common mining automatic control dust suppression device by water spray all is equipped with passive pyroelectric infrared sensor; It mainly acts on is to utilize the mode of human body sensing to control watering and lowering dust, and when the pedestrian gets into controlled area, passive pyroelectric infrared sensor detects the infrared signal that body temperature discharges; And signal delivered to controller; Stop watering by the relay control electromagnetic valve in the controller, guarantee that walk is not drenched, after the pedestrian leaves controlled area; Water curtain automatically recovers normal watering, realizes under the unmanned situation function of the timing auto spraying depositing dust tunnel in.
Yet; Passive pyroelectric infrared sensor on the existing mining automatic control dust suppression device by water spray all is on the correspondence position of fixing that is installed in mining automatic control dust suppression device by water spray; When the probe of needs adjustment passive pyroelectric infrared sensor towards the time; Must reinstall passive pyroelectric infrared sensor in the shift position, extremely inconvenient.
Summary of the invention
The object of the present invention is to provide a kind of its sensor probe towards adjustable mining passive pyroelectric infrared sensor, need not the shift position reinstall just can adjust its sensor probe towards.
For achieving the above object; The invention provides a kind of mining passive pyroelectric infrared sensor; Comprise sensor housing; The right-hand member of said sensor housing is equipped with sensor probe; The left end of said sensor housing is equipped with the aviation plug that is electrically connected with said sensor probe, and the bottom of said sensor housing is equipped with ball head universal, and the bulb that is positioned at said ball head universal bottom is installed in by binding ring under bulb upper locking ring and the bulb and cooperates the spherical hollow space that forms; Leave the locking spacing between the binding ring under said upper locking ring and the said bulb; Binding ring is positioned at by last locking cap and following locking bed and cooperates the cavity that forms under said bulb upper locking ring and the said bulb, and the said center of top that goes up locking cap has small top and big bottom adjustment spacing hole, and the top of said ball head universal is passed said adjustment spacing hole and is connected with the bottom of said sensor housing.
Mining passive pyroelectric infrared sensor of the present invention, said locking bed down is connected with through fixed bar and installs and fixes seat, and the said seat that installs and fixes is provided with mounting hole.
Mining passive pyroelectric infrared sensor of the present invention, said upward locking cap and said locking bed down are threaded.
The present invention is through at the sensor housing of mining passive pyroelectric infrared sensor with install and fix and be provided with a ball head universal between the seat; As required can be at any time during use through ball head universal adjustment be positioned at sensor housing upper sensor probe towards; Need not reinstall the shift position, very convenient.
Description of drawings
