Peripheral part, it is made to form advantageous etching condition.According to the actual fact, the corrosion condition of tank bottom bottom plate is most common
And most serious, analyzed according to related Investigation on Data, in tank stoppage in transit caused by crude oil storage tank is when corrode oil leak, bottom
Plate corrosion accounts for 76.4%.
It is generally stopped production at present to storage tank bottom plate using field operation, the detection mode of can opening.Such storage tank detection and dimension
Repair that there are the shortcomings of cost is high, detection time is long.Detect the generally reachable more than ten days duration of a large-scale atmospheric storage tank even
Several months.Due to the influence of above-mentioned factor, regular development field tank detection difficulty is larger, influences safety in production, live and past
Judge whether to need to carry out can opening detection toward effectively foundation is lacked, cause manpower, financial resource waste.
Invention content

A pair of of stud is symmetrically arranged on sensor cavity volume lateral wall, stud passes through the through-hole being correspondingly arranged in spring capping cover thus will
Spring capping is fixed on the top of sensor cavity volume.
In order to which cranse preferably is placed on storage tank bottom, it is not easy to slide, on the cranse lateral surface circumferentially
The upper multiple magnet pieces of clamping.
Preferably, the both ends of the surface of the semicircle garter spring extend perpendicularly outward to form two flangings, on the flanging
Equipped with bolt hole, bolt passes through the bolt hole on two semicircle garter spring flangings so as to which two semicircle garter spring fixations are spliced into one
Cranse, the mode being detachably connected in this way make two semicircle garter spring connections more stablize, are not easy to slide.
Preferably, the cranse is integrally formed with sensor cavity volume.
Advantageous effect：
1st, the present invention is realized in the case of not tank switching and clear tank, is monitored on-line using sound emission, realizes storage tank
Corrosion of base plate detects, very time saving, laborsaving.
2nd, acoustic emission detection sensor cavity volume of the invention is distributed on cranse circumferencial direction, thus facilitates multiple sound emissions
Detection sensor along storage tank outer wall circumferencial direction positioning, in addition, because spring capping and acoustic emission detection sensor cavity volume lead to
It crosses bolt to fix, acoustic emission detection sensor can first fix cranse, acoustic emission detection sensor is put on cranse when placing
Acoustic emission detection sensor cavity volume in, then spring capping is pressed on acoustic emission detection sensor, then pass through stud will
Spring capping is fixed with sensor cavity volume, taking and putting for acoustic emission detection sensor is facilitated, so as to reach Fast Installation
Sensor, the effect of accurate measuring signal.
