Description

Technical Field

[0001] This invention relates to the field of defect detection technology, and in particular to a device for detecting crack defects in porcelain insulators. Background Technology

[0002] Porcelain composite insulators have good anti-pollution capabilities, which can reduce the number of pieces used and thus reduce the string length, thereby reducing the height of the tower. They are also lightweight, which can improve the icing resistance of the tower and the line, saving a lot of steel and land area. If large-tonnage porcelain composite insulators are developed for use in ultra-high voltage projects, they will be of even greater significance.

[0003] Existing porcelain insulator crack defect detection devices mostly use optical detection methods. Since the cracks generated on porcelain insulators are relatively small, the contrast of the cracks on the insulator is low, which will affect the crack recognition rate of the optical equipment on the detection device and affect the detection effect of the device.

[0029] In specific application scenarios, the rapid feeding module 9 is mainly suitable for the rapid feeding stage in the rapid feeding process. Specifically, the rapid feeding module 9 uses the notched gear 905 and gear 903 to increase the speed at which the star disk 801 receives the insulator body 4, thereby improving the feeding efficiency of the device. The inclined guide block 912 can disrupt the symmetry of the insulator body 4 in the storage box 902, so that when the pusher block 913 pushes the insulator body 4, the insulator body 4 will not be blocked on the storage box 902. The storage box 902, threaded rod 914, spring 916 and rotating disk 917 can realize the automatic feeding of the device, reduce the inconvenience of manual feeding, ensure the continuity of feeding, and improve the smoothness of the device's detection process.

[0030] Working principle: Turning handle 915 causes the threaded rod 914 to rotate outwards, stretching and storing energy in spring 916. Simultaneously, the pusher block 913 moves to one side of the storage box 902. After placing the untested insulator body 4 into the storage box 902, slowly turn handle 915 back, causing the pusher block 913 to contact and press the insulator body 4 in the storage box 902 together. Under the action of the inclined guide block 912, the insulator bodies 4 on both sides of the storage box 902 are not symmetrically distributed. Insert the storage box 902 into the socket plate 901, connecting the storage box 902 to the feed inlet 803. Pull the closing plate 911 out of the slide rail 910. Under the pull of spring 916, the threaded rod 914 rotates. The pusher block 913 pushes the insulator body 4 at the front end into the groove of the socket plate 901. Motor 904 is activated, driving the notched gear 905 to rotate. This causes gear 903 to rotate the socket plate 901 by one-eighth of its circumference each time. The engaging rod 908 engages with the conical groove on the positioning plate 907 after each rotation. As the pusher block 913 continues to push to the position of the inclined guide block 912, the extension block 919 is pushed back into the receiving groove 918 by the inclined guide block 912. After the insulator body 4 enters the receiving box 3, the heating tube 802 is activated. The heating tube 802 heats the insulator body 4 in the star disk 801 to a temperature slightly above room temperature. Then, the hydraulic rod 834 is activated. The output end of hydraulic rod three 834 lifts the annular support plate 819 below the connecting port 804. Rotating the star disk 801 allows the insulator body 4 to fall from the connecting port 804 onto the annular support plate 819. Hydraulic rod two 826 is activated, pushing the linear airbag 828 to discharge air through the guide hole 817 into the annular airbag 818. The annular airbag 818 inflates and adheres to the inner wall of the insulator body 4, fixing the insulator body 4 in place. Hydraulic rod three 834 is activated again, and its output end retracts, immersing the insulator body 4 in the photochromic coating in the impregnation tank 7. After a period of cooling, the output end of hydraulic rod three 834 extends again and moves to the slide groove 806. At the designated position, motor 833 is started, driving gear 832 to rotate, thereby bringing the closed guide plate 831 in the inclined groove 829 together. Motor 825 is started, driving the insulator body 4 to rotate. Pump 815 is started, pumping water from the water storage tank 813 and spraying it out through the flushing nozzle 812 to clean the coating on the surface of the insulator body 4. The mixed liquid flows into the collection tank 838 through the guidance of the closed guide plate 831. Synchronous motor 809 is started, driving the transmission gear 810 meshing with the arc-shaped rack 811 to rotate, moving the mounting block 807 to the top of the arc plate 805. High-definition camera 5 and ultraviolet lamp 6 are activated.Ultraviolet lamp 6 illuminates the insulator body 4 with ultraviolet light filtered out by a filter. This causes the paint residue in the cracks on the insulator body 4 to darken upon contact with the ultraviolet light, creating a striking contrast with the porcelain-white surface of the insulator body 4. As the insulator body 4 rotates, the mounting block 807 moves gradually and uniformly downwards along the slide 806. A high-definition camera 5 records the detected high-contrast cracks. After this, the output end of hydraulic rod 826 retracts, recovering the air from the annular airbag 818. Motor 822 is activated, causing the insulator body 4 to rotate to one side. Hydraulic rod 820 is activated, causing the annular support plate 819 to push the insulator body 4 upwards, detaching it from the column 816 and allowing it to fall onto the inclined sorting plate 835. Based on the crack identification results, a rotating motor drives the guide rod 837 to rotate, causing qualified and unqualified insulator bodies 4 to slide into the sides of the separator plate 836.
