Description
Technical field
The utility model belongs to sensor technical field, is specifically related to a kind of mining level sensor of measuring water bunker level under the coal mine.
Background technology
Mining level sensor is used for the measurement to water level of ground or the inferior various industrial environments of mine, for mine monitoring, control system provide waterlevel data.The level sensor that generally adopts at present has float-type, electric pole type, ultrasonic type etc.And all there is certain shortcoming in above-mentioned level sensor, the float-type level sensor: float can occur stuck motionless, and incrustation scale, impurity clogging sensor cause poor reliability; The electric pole type level sensor: the sensing joint is long-term owing to receive the erosion of water, makes the life-span shorter, and has strengthened maintenance workload; Ultrasonic water level sensor: measuring accuracy receives such environmental effects such as water level fluctuation and temperature bigger, makes that the sensor measurement precision of this kind structure is low.
Summary of the invention
The purpose of the utility model is: provide that a kind of not only reliability is high, measuring accuracy is high, and the mining level sensor of being convenient to safeguard, to overcome the deficiency of prior art.
In order to achieve the above object, the technical scheme of the utility model is: a kind of mining level sensor comprises dust cap, joint, pressure transducer, sleeve, clamp nut and order wire; One end of said dust cap and joint is fixedly connected; Pressure transducer is positioned at the cavity of joint, and an end of the other end of joint and sleeve is tightly connected, and the other end and the clamp nut of said sleeve are tightly connected; The terminals of said order wire pass clamp nut and penetrate sleeve; Be electrically connected with pressure transducer, the exposed junction of order wire is by pressing plate and screw retention again, and said pressing plate is fixedly connected with clamp nut; Be respectively equipped with first pod apertures and second pod apertures on the said dust cap He on the joint, and first pod apertures and second pod apertures are conducted.
In technique scheme, be provided with first pad and first trim ring in the said joint, and an end of pressure transducer and first pad offset, the other end and first trim ring offset; The joint periphery has O-ring seal, and the other end of joint is tightly connected through an end of O-ring seal and sleeve.
In technique scheme, the other end of said sleeve is tightly connected through packing ring and second pad and clamp nut successively.
In technique scheme, said first pod apertures is an axial hole, and second pod apertures is a radial hole.
The good effect that the utility model had is: after adopting the utility model said structure; Because pressure transducer is positioned at the cavity of joint; And joint is connected with sleeve seal respectively with sleeve; Make pressure transducer in use not receive the influence of external influence factors, thereby not only reliability is high, measuring accuracy is high, and is convenient to safeguard.
