[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0023] The present utility model provides a technical solution: As Figures 1-4As shown in the figure, in this embodiment, an ultrasonic detection device for weld defects of a large storage tank includes: an adjustment mechanism 1. The adjustment mechanism 1 includes a top plate 11. Four corner positions at the bottom of the top plate 11 are each provided with a support column 12. The top of the support column 12 is provided with a bottom plate 13. Four corner positions at the bottom of the bottom plate 13 are each provided with a universal wheel 14. The tops of the four support columns 12 are respectively fixedly connected to the four corners at the bottom of the top plate 11, and the bottoms of the four support columns 12 are respectively fixedly connected to the four corners at the top of the bottom plate 13. Four corner positions at the bottom of the bottom plate 13 are each fixedly installed with a universal wheel 14. A motor 15 is arranged on the top of the top plate 11. A lead screw 16 is arranged at the bottom of the motor 15. A bearing seat 17 is arranged at the bottom of the lead screw 16. The outside of the motor 15 is butted in a card slot opened at the top of the top plate 11. The top of the lead screw 16 is butted with the output end at the bottom of the motor 15. The bottom of the lead screw 16 is fixedly connected to the inner surface of the bearing seat 17. The bottom side of the bearing seat 17 is fixedly connected to the top of the bottom plate 13. An adjustment shell 18 is arranged outside the lead screw 16. Two slide bars 19 are arranged between the top plate 11 and the bottom plate 13. The two ends of the two slide bars 19 are respectively fixedly connected to the opposite sides of the top plate 11 and the bottom plate 13. The outside of the lead screw 16 is in threaded connection with a threaded groove penetrated through the adjustment shell 18. The outside of the slide bar 19 is slidably connected to a chute penetrated through the top of the adjustment shell 18. Two cylinders 110 are arranged on one side of the adjustment shell 18. Two telescopic rods 111 are arranged on each side of the two cylinders 110 close to the adjustment shell 18. Two support plates 32 are fixedly connected to one side of the adjustment shell 18. Two cylinders 110 are respectively fixedly installed on the tops of the two support plates 32. One end of the telescopic rod 111 penetrates through a card slot opened in the adjustment shell 18 and is butted with the output end of the cylinder 110. The end of the telescopic rod 111 away from the cylinder 110 is provided with a detection plate 112. The other end of the telescopic rod 111 is fixedly connected to the side of the detection plate 112 close to the adjustment shell 18. A plurality of ultrasonic detection heads 33 are fixedly installed on the side of the detection plate 112 away from the telescopic rod 111. The end of the ultrasonic detection head 33 away from the detection plate 112 is provided with a tank body 31. Auxiliary mechanisms 2 are arranged on both the top and the bottom of the detection plate 112.

[0024] In this embodiment, when the staff needs to use the device to detect the weld of the storage tank, the device can be pushed by the universal wheels 14 to surround and detect the outside of the tank body 31. In addition, when the weld position outside the tank body 31 is too high or too low, the motor 15 can be started to drive the lead screw 16 to rotate. When the lead screw 16 rotates, the adjustment shell 18 and other components thereon will rise or fall synchronously. Then, the ultrasonic detection of the weld outside the tank body 31 is carried out through the detection plate 112 and the ultrasonic detection head 33, avoiding the staff from climbing or moving to the high position of the tank body 31 to hold the ultrasonic detection equipment for detection. In addition, when the distance between the weld of the tank body 31 and the ultrasonic detection head 33 is relatively far, two cylinders 110 can be started at the same time to push the telescopic rod 111 to extend, and then drive the detection plate 112 and the ultrasonic detection head 33 to approach the weld of the tank body 31. Therefore, the accuracy of the detection result can be improved.

[0025] As Figures 3-4 shown, the auxiliary mechanism 2 includes a mounting shell 21. Dust-proof breathable nets 22 are fixedly connected to both sides of the inner wall of the mounting shell 21. The mounting shell 21 and the detection plate 112 are threadedly installed through a mounting member 23. A plurality of fans 24 are fixedly installed inside the mounting shell 21.

[0026] In this embodiment, the mounting shell 21 and the fans 24 inside it can be installed on the detection plate 112 through the mounting member 23. After the detection plate 112 and the ultrasonic detection head 33 approach the weld of the tank body 31, the fans 24 can be started to rotate. The generated wind force can make the dust and impurities on the surface of the weld of the tank body 31 break away from its surface, thereby reducing the interference to the ultrasonic wave and improving the detection accuracy.

[0027] The utility model provides an ultrasonic detection device for weld defects of large storage tanks, and the specific working principle is as follows:

[0028] When the staff needs to detect the welds of the storage tank, a special device can be used to complete this task. This device is equipped with universal wheels 14, enabling the staff to easily push the device to surround and detect outside the tank body 31. This design allows the device to move freely around the tank body 31, facilitating a comprehensive detection of the welds. However, sometimes the weld positions outside the tank body 31 may be too high or too low. In this case, the staff can solve this problem by starting the motor 15. The start of the motor 15 drives the screw rod 16 to rotate, and the rotation of the screw rod 16 causes the adjustment shell 18 and other components on it to rise or fall synchronously. In this way, the device can adapt to weld positions at different heights, ensuring the accuracy and comprehensiveness of the detection. On the device, there are also equipped with a detection plate 112 and an ultrasonic detection head 33, which can perform ultrasonic detection on the welds outside the tank body 31. However, sometimes the distance between the weld of the tank body 31 and the ultrasonic detection head 33 may be relatively far. In this case, the staff can start two cylinders 110 simultaneously to solve the problem. These two cylinders 110 push the telescopic rods 111 to extend, driving the detection plate 112 and the ultrasonic detection head 33 to approach the weld of the tank body 31. In this way, the staff can perform ultrasonic detection more accurately, improving the reliability of the detection results. During the detection process, to reduce the interference of ultrasonic waves, the staff can also start the fan 24 to rotate. The wind generated by the fan 24 can make the dust and impurities on the surface of the weld of the tank body 31 break away from its surface, thereby reducing the interference with ultrasonic waves. In this way, the accuracy and reliability of ultrasonic detection will be further improved.
