The intrinsically safe type tearing sensor for the mine is characterized in that a tension sensor is arranged in the seal chamber, an electrical box (5) is arranged on the outer side of the seal chamber, an MCU module (14) and a power supply changeover module (15) for providing a power supply are arranged in the electrical box (5), an instrument amplifying circuit (16), a display screen (12), a key (13) and a relay (17) are connected with the MCU module (14) and arranged on the periphery of the MCU module (14), the instrument amplifying circuit (16) amplifies signals of the tension sensor and then inputs the signals to the MCU module (14), and the display screen (12) and the key (13) are arranged on the surface of the electrical box. Coal materials leaked when a belt tears are detected through the tension sensor, the MCU module receives data fed back by the tension sensor and conducts judgment and processing, and equipment connected to a relay contact in series is protected by controlling on-off of the relay, so that safety of coal transportation is guaranteed.
Description
Technical field
The present invention relates to mineral electrical apparatus field, specifically a kind of mining intrinsic safety type is torn sensor.
Background technology
In the underground transportation of colliery, whether the belt that conventionally adopts piezoresistive longitudinal rupture of adhesive tape sensor to detect ribbon conveyer has the situation of tearing, but this sensor of tearing can only play detection effect in the time that larger coal cinder falls, the tiny coal charge leaking down while having minute crack for belt has no idea to detect, and its inner rubber pad is easily aging and bullet does not get up, degradation, easily damages, and produce misoperation, can have a negative impact to transporting safely of colliery.
Summary of the invention
The object of the present invention is to provide mining intrinsic safety type to tear sensor, this is torn sensor and can find the situation of tearing at belt initial stage, and the reaction of dealing with in time, ensures the safety of Coal Transportation.
The technical solution adopted for the present invention to solve the technical problems is:
Mining intrinsic safety type is torn sensor, comprise top tray and lower tray, top tray and lower tray are fixedly connected to form seal chamber, described seal chamber inside is provided with tension pick-up, seal chamber sidepiece is provided with electrical box, in electrical box, be provided with MCU module and the power transfer module of power supply is provided, MCU module is arranged with coupled magnifier, read-out, button and relay outward, input MCU module after magnifier amplifies the signal of tension pick-up, read-out and button are arranged at electrical box box face.
Further, described MCU module periphery is also provided with coupled CAN module.
Further, described lower tray bottom is provided with bottom tray, and bottom tray bottom is provided with steel rope fixed leg.
Further, described top tray both sides are respectively equipped with the baffle plate that prevents that coal charge is unrestrained.
In such scheme, MCU module is common matured product, has acquisition of signal and logic operation processing capacity; CAN module is for realizing the communication between controller local area network, is widely used bussing technique; Tension pick-up can change and detect small pressure, is the electric product that stress monitoring is conventional.
The invention has the beneficial effects as follows; the coal charge leaking down during to belt tearing by tension pick-up detects; the data that MCU module receives tension pick-up feedback judge processing; and realize being serially connected in the protection of equipment in relay contact by the break-make of control relay, ensure the safety of Coal Transportation.
