Description
Technical Field
The utility model relates to the technical field of ultrasonic flaw detection electromechanical equipment, in particular to non-water immersion probe coupling type ultrasonic flaw detection equipment.
Background
In the industrial ultrasonic flaw detection, a coupling medium is required, and the coupling medium is determined by three main aspects of attenuation of ultrasonic waves by air, great reflection of ultrasonic waves caused by a great impedance difference of a gas-solid interface and low conversion efficiency of an ultrasonic probe. The most common and readily available coupling medium is water.
Fig. 1 illustrates an ultrasonic automatic detection device in the prior art, wherein an object to be detected is a valve 1, and the state illustrated in the figure is a conical surface for detecting the valve 1. As shown in fig. 1, the ultrasonic flaw detection adopts a water immersion coupling mode, a water tank 2 is filled with water, an ultrasonic probe 3, an ultrasonic probe 4 and conical surfaces of a valve 1 are completely immersed in the water, the valve 1 adopts a lying type and is horizontally arranged on two groups of driven bearings 5 and 6, an independent driving wheel 7 is connected through a motor 8, and the driving wheel 7 presses and drives the valve 1 to rotate in situ from above. However, this approach of the prior art has the following drawbacks: (1) When the valve 1 rotates in water, firstly, the valve can be influenced by water buoyancy, secondly, water can fill between the driving wheel 7 and the rod part of the valve 1, so that friction between the driving wheel 7 and the rod part of the valve 1 is reduced, valve slipping easily occurs in the rotating process of the valve 1, namely, the valve does not rotate, and therefore the ultrasonic probe does not complete detection of 360-degree circumference full coverage of the conical surface of the valve 1, and the risk of missed judgment exists. (2) Because the ultrasonic probe needs to be immersed in water for a long period of time and the driving wheel 7 is also in contact with water for a long period of time, corrosion is liable to occur, and the service life is reduced, which requires frequent replacement of these mechanisms, resulting in high use costs. (3) When the valve specification is changed, if the diameter change is large, the position of the ultrasonic probe must be adjusted to ensure that the probe is aligned with the conical surface, and meanwhile, the probe position adjustment is inconvenient due to refraction of water to light.
In view of the drawbacks of the prior art that may result in the above-mentioned reduced reliability of the detection results, it is currently necessary to change the coupling mode of such transmission to overcome the above-mentioned problems.

Referring to fig. 3, fig. 3 illustrates one group of ultrasonic probe mechanisms, and as shown in fig. 3, the interior of the front end nozzle 133 is in a cavity structure, the front end of the front end nozzle 133 is in a frustum shape with the diameter increasing from the front end surface to the middle, and the rear end is in a cylinder shape. A front through hole 133a is provided at the center of the front end surface of the front nozzle 133. The side of the front end bushing 133 is provided with a water pipe connection hole.

The ultrasonic probe 134 is connected to the ultrasonic probe connection hole of the rear end surface of the front end bushing 133, and the connection part can be sealed by using a conventional sealing material such as a sealing ring or a sealing tape and a sealing mode, and the ultrasonic probe 134 and the front end through hole 133a after being mounted are on the same straight line, so that ultrasonic waves can be emitted outwards through the front end through hole 133a.
One end of the water pipe 131 is connected with a side water pipe connection hole of the front end bushing 133, and the other end of the water pipe 131 passes through a water pipe through hole on the side wall of the water tank 11. The water pipe 131 is connected to an external water pipe outside the water tank, a water pump is provided in the water pipe, and external water flow is delivered to the internal cavity structure of the front-end nozzle 133 through the water pipe 131 and flows out from the front-end through hole 133a. The water pipe is preferably a hose so that the hose affects the change in position of the ultrasonic probe 134 when it is desired to make a position adjustment.
A throttle valve 132 is installed at the junction of the water pipe 131 and the water pipe connection hole, and the throttle valve 132 is used for adjusting the flow rate and the flow velocity of water.
