The suction cup cover realizes close contact between the probe and the workpiece to be detected through the negative pressure chamber and the airbag assembly. The water supply system uses water self-weight to inject it into the inner cover body to achieve coupling.
Compared with the traditional water immersion or water spraying method, this device has the advantages of less water and stable coupling, which effectively reduces probe wear and improves the water-saving effect of detection.

[0022] An automatic coupling device for ultrasonic detection of special equipment provided by the embodiment, such as Figures 1 to 3As shown in the figure, it includes a telescopic rod 2 and an ultrasonic probe 3 installed at the end of the telescopic rod 2. The telescopic rod 2 is fixed on the ultrasonic detection device. The suction cup cover 1 is fixedly installed at the telescopic end of the telescopic rod 2. The telescopic rod 2 controls the suction cup cover 1 to approach or move away from the workpiece to be detected, that is, controls the ultrasonic probe 3 to approach or move away from the workpiece to be detected, realizing automatic coupling detection. The automatic coupling device further includes a suction cup cover 1, a water supply system, an airbag assembly 4 and an air pump 7. The suction cup cover 1 is fixedly installed at the telescopic end of the telescopic rod 2 and covers the outside of the ultrasonic probe 3. The suction cup cover 1 includes an outer cover 101 and an inner cover 102. The inner cover 102 is fixedly connected inside the outer cover 101. An annular negative pressure chamber 103 is formed between the outer cover 101 and the inner cover 102. The ultrasonic probe 3 is fixedly installed inside the inner cover 102. A water injection pipe 8 is provided on the inner cover 102, and the water injection pipe 8 extends outside the outer cover 101; the airbag assembly 4 is fixedly arranged inside the inner cover 102. The airbag assembly 4 is annular and can be sleeved outside the ultrasonic probe 3. The air injection port of the airbag assembly 4 is led outside the suction cup cover 1 and is connected to the air pump 7 through a first air pipe 5. The air pump 7 supplies air to the airbag assembly 4, and the air pump 7 is communicated with the negative pressure chamber 103 through a second air pipe 13 to pump out the air inside the negative pressure chamber 103.
[0023] The air pump 7 is used to pump out the air inside the negative pressure chamber 103, so that a negative pressure state is formed inside the negative pressure chamber 103. Thus, when the suction cup cover 1 is attached to the surface of the workpiece to be detected, the suction cup cover 1 is tightly adsorbed on the surface of the workpiece to be detected. The ultrasonic probe 3 is fixedly installed inside the inner cover 102. The water supply system relies on the self-weight of water to flow into the inside of the inner cover 102, that is, the water supply system is arranged at a position higher than the inner cover 102, and water can flow into the inner cover 102 by itself without using a water pump. The airbag assembly 4 is fixedly arranged inside the inner cover 102. The air pump 7 is used to supply air to the airbag assembly 4. The air pump 7 supplies air to the airbag assembly 4, causing the airbag assembly 4 to inflate and expand, thereby occupying a certain space inside the inner cover 102, making the water in the inner cover 102 fill the inside of the inner cover 102, realizing the coupling of the ultrasonic probe 3.
[0024] In one embodiment, as Figure 3 shown, a first fitting portion 101a is fixedly provided at the bottom edge of the outer cover 101, and a second fitting portion 102a is provided at the bottom edge of the inner cover 102. Both the first fitting portion 101a and the second fitting portion 102a are made of flexible materials, such as rubber materials, so that the bottom edge of the outer cover 101 and the bottom edge of the inner cover 102 can closely fit the surface of the workpiece to be detected.
[0025] In one embodiment, as Figure 2As shown, the water supply system includes a water tank 9, which is arranged at a position higher than the sucker cover 1. The water outlet end of the water tank 9 is communicated with the water inlet end of the water injection pipe 8. One end of the water injection pipe 8 is located in the central cavity 104 inside the inner cover 102, and the water injection pipe 8 is fixedly connected to the sucker cover 1. A first stop valve 10 is installed on the water injection pipe 8. When the first stop valve 10 is controlled to open, the water inside the water tank 9 can automatically flow into the central cavity 104 through the water injection pipe 8.
[0026] In one embodiment, as Figure 2 shown, the air inlet end of the air pump 7 is fixedly connected with a second air pipe 13. One end of the second air pipe 13 is located inside the negative pressure cavity 103, and the second air pipe 13 is fixedly connected to the sucker cover 1. A second branch pipe 14 is arranged on the side of the second air pipe 13. A throttle valve 15 is installed on the second branch pipe 14. The throttle valve 15 makes the air intake of the second branch pipe 14 small. The air outlet end of the air pump 7 is fixedly connected with a first air pipe 5. The first air pipe 5 is connected to the airbag assembly 4, and a second stop valve 11 is installed on the first air pipe 5. A first branch pipe 6 is fixedly connected to the side of the first air pipe 5 and between the second stop valve 11 and the air outlet end of the air pump 7. A third stop valve 12 is installed on the first branch pipe 6.
[0027] When in use, the second stop valve 11 is opened and the third stop valve 12 is closed. The air pump 7 is powered on to work. The air pump 7 pumps air from the second air pipe 13 and the second branch pipe 14. In the early stage, due to the installation of the throttle valve 15 on the second branch pipe 14, the gas flow in the second branch pipe 14 is blocked, and air can be pumped better from the second air pipe 13, and the inside of the negative pressure cavity 103 is pumped into a vacuum. In the later stage, the power of the air pump 7 can be adjusted to a smaller value to maintain the negative pressure inside the negative pressure cavity 103. In the early stage of the operation of the air pump 7, the air outlet end of the air pump 7 sends air into the airbag assembly 4 through the second branch pipe 14, so that the airbag assembly 4 expands. After the airbag assembly 4 expands to a suitable size after supplying air for a period of time, the second stop valve 11 is opened and closed, and the third stop valve 12 is opened. In the later stage, the air pump 7 works with a small power.
[0028] In one embodiment, the first stop valve 10, the second stop valve 11, and the third stop valve 12 are all solenoid valves; a controller 16 can also be set. As Figure 4 shown, the controller 16 is electrically connected to the first stop valve 10, the second stop valve 11, the third stop valve 12, and the air pump 7. The controller 16 controls the power-on of the air pump 7 according to the above principle, and controls the opening / closing of the first stop valve 10, the second stop valve 11, and the third stop valve 12.
[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
