[0028] Example 1:

[0029] A non-destructive testing device with dust removal function, in order to improve dust removal efficiency, such as... Figures 1 to 4 As shown, the system includes a collection box 1, with a fixing part for clamping pipe fittings installed on the top of the collection box 1. A U-shaped plate 5 is fixed to the top outer wall of the collection box 1 by bolts, and a limit frame 24 is fixed to the top outer wall of the U-shaped plate 5 by bolts. A sliding seat 23 is slidably connected to the outer wall of the limit frame 24. A connecting plate 31 is welded to one side outer wall of the sliding seat 23. An electric telescopic rod 22 is fixed to the top outer wall of the connecting plate 31 by bolts. A detection probe 32 for non-destructive testing of pipe fittings is fixed to the output end of the electric telescopic rod 22. An electric telescopic rod 35 is fixed to one side outer wall of the upright plate 8 by bolts, and a fixing frame 27 is fixed to the output end of the electric telescopic rod 35 by pins. Spray nozzles 28 are fixed to the inner walls of both sides of the fixing frame 27 by brackets. A connecting seat 29 is welded to the top of the fixing frame 27. A sliding plate 30 is rotatably connected to the inner wall of the connecting seat 29. A sliding sleeve 26 that is rotatably connected to the sliding plate 30 is slidably connected to the inner wall of the sliding seat 23.

[0030] The pipe to be nondestructively detected can be fixed by the fixing part, and the pipe weld is cleaned before detection to ensure the accuracy of subsequent detection. When cleaning, the electric telescopic rod three 25 drives the fixed frame 27 and the nozzle 28 to move forward. When the nozzle 28 moves above the pipe weld, the nozzle 28 is connected to the hose, water pump and other mechanisms through the joint, and the nozzle 28 is used to flush the pipe weld to remove dust on the pipe weld. After cleaning, the electric telescopic rod three 25 drives the nozzle 28 and the fixed frame 27 to move backward, so that the fixed frame 27 and the nozzle 28 gradually move backward. At the same time, the sliding sleeve 26 and the sliding plate 30 are connected to make the sliding seat 23 slide along the limiting frame 24, and the moving direction of the sliding seat 23 is opposite to that of the fixed frame 27. When the detection probe 32 moves above the pipe weld, the electric telescopic rod two 22 drives the detection probe 32 to move downward. When the detection probe 32 and the pipe weld are attached, the detection probe 32 is used to nondestructively detect the pipe weld.

[0031] The nondestructive detection method in the embodiment is preferably ultrasonic detection, wherein the detection probe 32 is an ultrasonic detection probe. The working principle is that the detection probe 32 converts electrical signals into ultrasonic signals. The piezoelectric crystal in the detection probe 32 produces mechanical vibration under the action of an electric field, thereby emitting ultrasonic waves. The ultrasonic waves enter the weld from the detection probe 32 and propagate at a certain angle. When encountering defects such as cracks, pores and slag in the weld, the ultrasonic waves are reflected, refracted or scattered. The reflected waves are received by the detection probe 32 and converted into electrical signals. The amplitude, time and frequency changes of the reflected waves reflect the nature, size and position of the defects. The received signals are amplified and processed and displayed on the screen (not shown). The operator can judge the quality of the weld according to the waveform characteristics.

[0032] The pipe comprises two pipe bodies 4, and the two pipe bodies 4 are welded and fixed.

[0033] After the two pipe bodies 4 are welded, a weld is formed between the end portions of the two pipe bodies 4. The weld is cleaned to nondestructively detect whether defects exist in the weld.

The fixing part further comprises a driving motor 7 and a vertical plate 8. The vertical plate 8 is fixed to the top outer wall of the collecting box 1 by bolts, and the driving motor 7 is fixed to one side outer wall of the vertical plate 8 by bolts. The output end of the driving motor 7 is connected with the clamping seat two 6 through a coupling.

[0035] When the pipe needs to be fixed, first, the pipe is placed between the clamping seat one 3 and the clamping seat two 6, the clamping seat one 3 and the clamping seat two 6 are driven to move transversely by the electric telescopic rod one 12, so that the clamping seat two 6 and the clamping seat one 3 finally fix the pipe by clamping, the inside of the clamping seat two 6 and the clamping seat one 3 is a conical structure, the conical structure and the end of the pipe are closely fitted, so the stability of the pipe during clamping can be effectively guaranteed, after the pipe is clamped and fixed, the pipe can be driven to rotate by the driving motor 7, so that the nozzle 28 can clean the weld more uniformly, and when the driving motor 7 drives the pipe to rotate at a high speed, the water remaining on the pipe after cleaning can be thrown out under the action of centrifugal force, so that the drying rate of the weld is accelerated.

[0036] The outer wall of one side of the collecting box 1 is fixed with a liquid discharge valve 9 through bolts;

[0037] The collecting box 1 can collect the waste liquid after cleaning, and when the liquid discharge valve 9 is opened, the waste liquid can be discharged.

[0038] The outer wall of one side of the collecting box 1 is fixed with a controller 10;

[0039] The controller 10 can be used to control the driving motor 7, the electric telescopic rod one 12, the electric telescopic rod two 22 and the electric telescopic rod three 25.

[0040] Working principle: the pipe is placed between the clamping seat one 3 and the clamping seat two 6, the electric telescopic rod one 12 is started to drive the moving plate 2 and the clamping seat one 3 to move transversely, the clamping seat two 6 and the clamping seat one 3 clamp and fix the pipe, the inside of the clamping seat two 6 and the clamping seat one 3 is a conical structure, which closely fits the end of the pipe to ensure the stability of clamping, after fixing, the driving motor 7 is started to drive the pipe to rotate, the electric telescopic rod three 25 drives the fixed frame 27 and the nozzle 28 to move forward, when the nozzle 28 moves above the pipe weld, the nozzle 28 is connected through the joint, hose, water pump and other mechanisms, and the nozzle 28 is used to flush the pipe weld to remove dust, after dust removal, the electric telescopic rod three 25 drives the nozzle 28 and the fixed frame 27 to move backward, in the process of moving backward, the sliding sleeve 26 and the sliding plate 30 are linked to make the sliding seat 23 slide along the limiting frame 24, and the moving direction of the sliding seat 23 is opposite to that of the fixed frame 27, when the driving motor 7 drives the pipe to rotate at a high speed, the water remaining on the pipe after dust removal is thrown out under the action of centrifugal force, which speeds up the drying rate of the weld, when the detection probe 32 moves above the pipe weld, the electric telescopic rod two 22 is started to drive the detection probe 32 to move down, when the detection probe 32 and the pipe weld are closely fitted, the detection probe 32 is used for nondestructive testing of the pipe weld, the controller 10 is used to control the driving motor 7, the electric telescopic rod one 12, the electric telescopic rod two 22 and the electric telescopic rod three 25 to realize the cooperative work of each component.
