Description

A kind of load box Displacement sensor under water
Technical field
The invention belongs to Architectural Equipment technical fields, and in particular to a kind of load box Displacement sensor under water.
Background technique
The detection of pile measurement load box underwater displacement, load box are embedded to the minus tens meters of depths in ground in advance with foundation pile, are adding Load lower box part pile body can be generated to bottom offset when pressure, and load box pile body is generated and is displaced.Method before this is at load box bottom Portion, top connect reinforcing bar, as displacement guide rod, displacement conduction to ground are carried out displacement measurement, has the precision of measurement low, The defects of measurement is inconvenient.
The purpose of the present invention is removing pervious conduction reinforcing bar, directly load box Displacement sensor under water is put with cable Enter on each test point of load box, one section of cable is fixed on datum line beam.
Summary of the invention
It the purpose of the present invention is to solve the above problems, and proposes a kind of load box Displacement sensor under water, senses Device has underwater operation, high-precision and high reliability, solves tradition in load box bottom, top connection reinforcing bar, as displacement The defects of displacement conduction to ground is carried out displacement measurement, has the precision of measurement low by guide rod, and measurement is inconvenient.
The present invention provides a kind of load box Displacement sensor under water, comprising:
It is displaced casing, multiple displacement casings are installed on load box;
Underwater magnetic displacement transducer, multiple underwater magnetic displacement transducers are uniformly placed on each test point of load box, It is connected using cable with underwater magnetic displacement transducer, the underwater magnetic displacement transducer includes magnetic bar and stainless steel tube protection Set, the magnetic bar are inserted into stainless steel tube protective case, and the stainless steel tube protective case top periphery is equipped with a circle magnet ring.
As preferred means, it is fixed by bolts at the stainless steel tube protective case upper end opening, the magnet ring and bolt Between install a chip shield.
As further preferred means, stainless steel tube protective case lower half is clump weight.
As further preferred means, the head peace of the underwater magnetic displacement transducer insertion stainless steel tube protective case Equipped with retaining ring.
As further preferred means, the underwater magnetic displacement transducer is provided with 2-8.
As further preferred means, when measurement, the rear cable is positioned and is fixed in datum line beam using wire clamp.
The invention has the advantages that: 1, Displacement sensor under water, are accurately detected by internal contactless observation and control technology The absolute position of movable magnet ring measures the actual displacement value of detected product, and sensor has underwater operation, high-precision, Gao Ke By property, solves tradition in load box bottom connection reinforcing bar and be transmitted to ground survey displacement in displacement casing, there is measurement Precision is low, measures inconvenient defect problem.2, a chip shield is installed between magnet ring and bolt, is placed on and tightens bolt When, bolt damages magnet ring;Clump weight increases the weight of magnetic displacement transducer entirety, is conducive to magnetic displacement sensing The sinking of device, the retaining ring setting on magnetic displacement transducer head, prevents in magnetic bar moving process, magnetic club head touches stainless steel Bottom end in protection of pipe set, damages magnetic bar, and magnetic displacement transducer is provided with two to eight, can be according to magnetic displacement transducer Misalignment detect whether displacement point when load box or more is subjected to displacement.
