Description

[0001] The present invention belongs to the technical field of non-destructive testing, and in particular relates to an in-situ high-precision non-destructive testing device for deep-sea components. Background Art

[0002] Deep-sea parts refer to structural components that are operated directly on the seabed during maintenance and installation work in the deep sea. These parts are usually designed to withstand extreme conditions such as high pressure, low temperature and seawater corrosion, and can operate stably for a long time in deep-sea environments. Deep-sea parts play an important role in marine engineering and seabed resource development.

[0003] The surface of this type of parts is exposed to extreme conditions such as high pressure and high salt when in use. Therefore, non-destructive testing of the surface of the parts is required during normal use and after the damaged parts are repaired in situ to avoid damage such as cracks on the surface of the parts that may make them unusable in the deep sea.

[0004] When using existing deep-sea parts in-situ surface non-destructive testing equipment, optical sensors are generally used to detect the surface of parts. However, during use, they are affected by the diversity of testing postures and testing environments, which can easily cause optical sensor shaking, making it difficult to achieve the ideal testing motion trajectory, and making it easy to generate errors during scanning testing, thereby reducing the detection accuracy. The low-precision test results are difficult to provide key basis for subsequent deep-sea in-situ repairs, further causing the damage to rapidly deteriorate in the extreme deep-sea environment, resulting in serious losses.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) When the elliptical block contacts the rotating wheel, the splint on the rotating wheel moves within the guide sleeve through the guide rod, and the tension spring is in a compressed state, thereby causing the moving rack to engage the active gear and rotate, so that the first pulley on the active shaft drives the matching shaft on the second pulley to rotate through the conveyor belt, and further causes the engaging gear to rotate and drive the extension rods on the two engaged split racks to move toward each other in the engaging horizontal block, so that the two error correction square plates are matched and connected to the rectangular square grooves on the rectangular block, and the elliptical block is reset when it no longer contacts the rotating wheel; so that when the rectangular block deviates during movement, it can be adjusted by two The reciprocating movement of the error correction square corrects the orientation of the rectangular block and restores and maintains it in the center position, thereby preventing the laser scanner from shaking during use, improving the stability of the laser scanner during use, and allowing the laser scanner to stably scan and detect parts in the current plane position, avoiding errors in the detection results, thereby improving the accuracy of the detection results. The laser scanner can move in the directions of the X and Y axes and can scan and image parts at different positions and angles, further improving the imaging effect, and improving the accuracy of the detection results;

[0019] (2) When the operator needs to adjust the angle of the non-destructive testing box, the operator pulls down the flow cross block, and the flow cross block moves to the upper limit of the limit rod provided in the limit groove. The limit spring is in a stretched state, so that the locking rod contacts the limit setting of the rotating circular plate. After the operator adjusts the required angle of the non-destructive testing box, the operator releases the flow cross block, so that the limit spring is reset, and the locking rod re-limits the rotating circular plate, thereby reducing the rotation of the rotating circular plate caused by non-human factors and improving the stability of the device during the experiment;

[0020] (3) The two moving plates move toward each other in the constant guide rod on the balance slot, and the constant spring is in a stretched state. When the moving contact pieces on the two moving plates come into contact with the static contact pieces, the drive motor is controlled to reverse, so that the brake horizontal plate is reset and moved toward the direction close to the linkage base, so that the laser scanner on the brake horizontal plate continues to scan the non-destructive testing box back and forth, further improving the accuracy of the scanning imaging;

[0021] (4) The brake horizontal plate is limited in movement in the limit column provided on the limit groove by the limit vertical block, so as to avoid the brake horizontal plate from shaking when moving, thereby improving its stability during movement, making the limit spring in a compressed state, and then making the pull rope drive the movable slider to move in the movable slide groove, making the extrusion spring in a compressed state, and then making the fixed rack move, so that the linkage gear meshed with the fixed rack rotates, so that the driving bevel gear on the linkage shaft meshes with the compound bevel gear to rotate, and then drives the transmission helical gear to rotate, and the special-shaped rod makes the fixed horizontal plate on the rectangular block to move back and forth in the four auxiliary wheels, so that the two laser scanners on the bottom surface of the fixed horizontal plate move back and forth on the non-destructive testing box, so that the laser scanner can scan and detect the placed parts at different positions on the non-destructive testing box, so that the laser scanner can move on the X-axis, so that the information of the parts during scanning is richer, and the scanning imaging efficiency and the accuracy of the scanning results are improved.

[0022] (5) The operator turns the handle to rotate the rotating shaft in the first bearing, so that the active bevel gear meshes with the driven bevel gear to rotate, and then drives the rotation of the driving threaded shaft, so that the lifting block connected to the driving threaded shaft moves upward in the guide column. The guide spring is in a compressed state, and the supporting double rods and the non-destructive testing box are in a state of active connection, so that the non-destructive testing box is in an inclined position. At this time, the part to be tested is fixed, so that the laser scanner on the non-destructive testing box can rotate around the part, thereby adjusting the collection angle of the laser scanner, so that it can perform multi-directional scanning and detection of the part at different angles, reducing the existence of blind spots in the scanning detection, and increasing the detection range, avoiding the laser scanner from being unable to complete the detection of the entire part due to the existence of blind spots when scanning and detecting the part, thereby avoiding errors in the detection results and improving the accuracy of the detection results; at the same time, during the process of non-destructive testing of the part, the operator does not need to manually adjust the position of the part, thereby reducing the workload of the staff.

The constant spring 72 is in a stretched state. When the moving contact piece 73 on the two movable plates 69 contacts the static contact piece 74, the control drive motor 20 is reversed, causing the brake cross plate 25 to reset and move in the direction close to the linkage base 5, so that the laser scanner 66 on the brake cross plate 25 continues to scan the non-destructive testing box 18 back and forth, further improving the accuracy of the scanning imaging.
