Description
Technical field
The present invention relates to ultrasonic detection device, especially relate to a kind of adaptive overflow type seal shoe for ultrasonic probe.
Background technology
Ultrasound examination is under the prerequisite of the duty of not damaging tested part, to being verified a kind of detection means that the surface that loses and internal soundness are checked.Ultrasound wave will produce reflection, refraction and wave mode conversion on the interface of foreign medium, utilize these characteristics, can obtain the reflection wave that reflects from defect interface, thereby reach the purpose of detecting defects.Ultrasound wave can have effect spread in media such as gas, liquid, solid, solid solution.Wherein, it is the most extensive with water to be that the method for medium is used, and comprises water seaoning, water space method, water jet column method, spilling water method etc.
During with overflow type ultrasound examination tested part, be that medium preferably is filled in water between ultrasonic probe and the tested part with water, because when having air between ultrasonic probe and the seized part, ultrasound wave will be reflected and can't get into seized part.
Existing overflow type ultrasound examination equipment designs different ultrasonic probe boots for detecting the tubing class part of different-diameter, when needs detect the part of different-diameter, then needs transducer set ultrasonic probe boots, has both wasted time and energy, and has reduced detection efficiency again.
Summary of the invention
Waste time and energy during to overflow type ultrasound examination Equipment Inspection different-diameter tubing class part; The shortcoming of inefficiency; The purpose of this invention is to provide a kind of adaptive overflow type seal shoe for ultrasonic probe; With the tubing class part of self-adaptation different-diameter, and need not change the ultrasonic probe boots, watertight is encapsulated between probe and the seized part.
For solving the problems of the technologies described above, technical scheme of the present invention is:
Ultrasonic probe is installed in the center pit of fixed block, on fixed block, has a circle water annulus, and with sealing shroud ultrasonic probe and water annulus is isolated; The straight water channel water delivering orifice in water annulus lower end is in the fixed block lower surface; The straight water channel water inlet in water annulus upper end is in the fixed block upper surface; Outside the straight water channel in the upper end of fixed block, have a plurality of guide through hole that are uniformly distributed with on the circle, the ring groove that open the lower end, be separately installed with guide pillar in each guide through hole, all there is screw thread at the two ends of guide pillar; Be installed in the outer guide pillar one end attaching nut of fixed block; Guide pillar one end that is installed in the fixed block connects the resilient seal post, and there is one section diameter the guide pillar centre that is positioned at fixed block than big column, and spring is fixed on guide pillar than between great circle cylinder and the pickup groove.
The beneficial effect that the present invention has is:
Adopt the tubing class part that structure of the present invention can the self-adaptation different-diameter to seal, and need not change the ultrasonic probe boots, can water be sealed between probe and the seized part well, time saving and energy saving, efficient is high.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further description.
Like Fig. 1, shown in Figure 2, ultrasonic probe 1 is installed in the center pit of fixed block 3, on fixed block 3, has a circle water annulus, and with sealing shroud 2 ultrasonic probe 1 and water annulus is isolated; The straight water channel water delivering orifice in water annulus lower end is in the fixed block lower surface; Straight water channel 7 water inlets in water annulus upper end have a plurality of guide through hole that are uniformly distributed with on the circle, the ring groove that open the lower end in the fixed block upper surface outside the straight water channel 7 in the upper end of fixed block 3, be separately installed with guide pillar 4 in each guide through hole; All there is screw thread at the two ends of guide pillar 4; Be installed in fixed block 3 guide pillar 4 one end attaching nuts 5 outward, guide pillar 4 one ends that are installed in the fixed block 3 connect the resilient seal post, and there is one section diameter guide pillar 4 centres that are positioned at fixed block 3 than big column; And spring 8 is fixed on guide pillar 4 than between great circle cylinder and the pickup groove, total constitutes a probe seal shoe.
Like Fig. 3, shown in Figure 5, the described ring groove of opening is square ring groove or circular ring-shaped groove.
Like Fig. 3, shown in Figure 4, when described ring groove is square ring groove, described resilient seal post, its cross section is square resilient seal post 9, square resilient seal post 9 adjacent being arranged in the square ring groove.
Like Fig. 5, shown in Figure 6, when described ring groove is the circular ring-shaped groove, described resilient seal post, its cross section is fan-shaped resilient seal post 11, fan-shaped resilient seal post 11 adjacent being arranged in the circular ring-shaped groove.
Principle of work of the present invention is following:
As shown in Figure 1, when seized part 10 needs to detect, be placed under the probe seal shoe; And with certain strength seized part 10 is upwards pushed away, will resilient seal post and guide pillar 4 upwards be boosted together like this, guide pillar 4 pushes away downwards under the spring force effect of spring 8 again simultaneously; Make resilient seal post 9 receive downward thrust again; Therefore elastic deformations can take place in resilient seal post 9, and lower surface be along with distortion can be fitted with seized part 10 each other, the resilient seal post that forms a circle 9 each all with seized part 10 applyings; And also fit each other between the resilient seal post 9; Like this, fixed block 3, guide pillar 4, ultrasonic probe 1, seized part 10 have just formed seal cavity, and water can be enclosed in this seal cavity well.
The minimum diameter of the seized part 10 that the present invention can detect must be than the inboard distance of two-side elastic sealing column slightly more greatly; Just equal the distance of two-side elastic sealing column inboard when the diameter of seized part 10; As shown in Figure 2; Outermost resilient seal post and guide pillar 4 are depressed into the position that nut 5 touches fixed block 3 in the spring force effect of spring 8, and spring 8 is raised to the longest; Outermost resilient seal post does not receive elastic deformation, does not reach best sealing effectiveness.
There is screw thread the upper end of guide pillar 4, is connected with nut 5 through screw thread, and purpose has two: guarantee that one, spring 8 can pack into from this end smoothly; Two, can adjust the position of guide pillar 4 and resilient seal post through above that the nut 5 of being rotationally connected, and the elastic force of spring 8.
Fixed block 3 is offered the straight water channel 7 in a upper end between ultrasonic probe 1 and pilot hole; Straight water channel 7 upper ends, upper end are connected with external water source through water pipe head 6; The lower end splits into a circle water annulus with the straight water channel 7 in upper end, and water annulus flows in the seal cavity through the straight water channel in lower end.If adopt structure shown in Figure 5, the seal cavity of formation is square; If adopt structure shown in Figure 6, the seal cavity of formation is circular.
The detectable minimum diameter of adaptive overflow type ultrasonic probe boots of the present invention is to be a bit larger tham the inboard distance of two-side elastic sealing column, and maximum gauge can approach infinity be dull and stereotyped.
