Description
Technical field
The utility model is related to sensor probe fixing device, is particularly used for storage tank, pressure vessel, pressure pipeline, valve
The acoustic signal sensor probe fixing device of the acoustical signal processing of door etc..
Background technology
Traditional detection technique, such as ray detection, ultrasound examination, Liquid penetrant testing, TOFD detection, Magnetic Flux Leakage Inspecting etc. are detected
Technology all needs arrestment operation to be detected again；Particularly for large-scale storage tank, not only need to stop tank, in addition it is also necessary to can opening,
Clear tank, can thus increase very big human and material resources and financial resources cost, particularly duration cost.Therefore, the can opening detection of storage tank
Often the general overhaul along with storage tank is together carried out, and for the storage tank without the plan of major repair, traditional detection method
It is helpless.Acoustical signal processing technology is a kind of active defects detection technique, is applicable not only to metal inside defect, may be used also
For the application of the detection of plastics, pottery, concrete etc., petroleum industry equipment, facility and pressure pipeline etc. is can be widely applied to
On-line checking.The application of acoustical signal processing technology, is conducive to shortening detection cycle and cost, also advantageously improves efficiency.Therefore,
A kind of device that can quickly, conveniently fix acoustical signal processing probe is needed, and requires that the device is compact, light, can be fast
Speed dismounting, and extra acoustical signal signal is not produced, negative impact is brought to detection, in prior art, do not have which kind of dress
Put and can realize above-mentioned functions.
Content of the invention
In order to solve defect present in above-mentioned prior art, the utility model provides a kind of acoustic signal sensor probe
Fixing device, can be designed by the feature of magnet adsorption using tested equipment.
The technical solution adopted in the utility model：A kind of acoustic signal sensor probe fixing device, including an outside framework
And hold down gag, the top of outside framework is provided with hole, and hold down gag includes briquetting and the movable axis being connected with briquetting；Described activity
Axle is stretched out through the hole of housing top of the trellis, and the part that described movable axis is stretched out from outside framework is provided with nut, and movable axis is outside
Spring is cased between part and briquetting in framework；Bar magnet is provided with described outside framework bottom.
Preferably, described bar magnet is bolted installed in the inner side of outside framework.
Preferably, the absorption affinity of described bar magnet is more than the maximum elastic force of spring.
The beneficial effects of the utility model：Manufactured by carbon steel using tested measurement equipment, have the characteristics that magnetic adsorbability, by filling
Put the paired magnet for using and acoustical signal probe is absorbed and fixed at detected equipment surface, in fixing probe, probe is fixed
Spring-compressed on device provides certain pressure, and fixing for probe equipment under test surface, the pressure of spring are less than whole device
Magnetic adsorbability, the device have can quickly, the device of convenient fixing acoustical signal processing probe, the device is compact, light, energy
Enough fast assembling-disassemblings, pretightning force is adjustable, and does not produce the advantage of extra acoustical signal signal.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure, 1- bar magnet, 2- bolt, 3- outside framework, 4- hold down gag, 4.1- briquetting, 4.2 movable axis, 5- spring,

Specific embodiment
In order to further illustrate ins and outs of the present utility model, illustrate in conjunction with the drawings and specific embodiments.
As shown in figure 1, this device includes an outside framework 3 and hold down gag 4, the top of outside framework 3 is provided with hole, compression dress
Putting 4 includes briquetting 4.1 and the movable axis 4.2 being connected with briquetting 4.1；Described movable axis 4.2 is stretched through the hole at 3 top of outside framework
Go out, the part that described movable axis 4.2 is stretched out from outside framework 3 is provided with nut 6, part of the movable axis 4.2 in outside framework 3 and
Spring 5 is cased between briquetting 4.1；Bar magnet 1 is provided with described 3 bottom of outside framework.
In the present embodiment, described bar magnet 1 is fixed by bolt 2, bar shaped magnetic installed in the inner side of outside framework 3
Iron 1 is used in pairs, and in the present embodiment, outside framework 3 is cylinder, and bar magnet 1 is in 3 inner side line centered on circular diameter of outside framework
It is symmetrically installed, to ensure each several part uniform force, described bar magnet 1 is more than spring 5 most to the absorption affinity of tested equipment
Big elastic force, so as to ensure that fixing device will not be backed down by probe.
During use, by the position of adjusting nut 6, the pretightning force of briquetting 4.2 is set.Acoustical signal processing is being carried out to storage tank
When, sonic transducer probe distance tank bottom about 500mm, probe are coupled using rosin with tank skin, use acoustic signal sensor after coupling
Probe fixing device is fixed, and bar magnet 1 adsorbs fixing device on tube wall, and briquetting 4.2 is firmly pressed in acoustical signal
On sensor probe, acoustical signal probe thrust can be reached by adjusting spring 5, will not produce extra acoustical signal.
