Description

Technical Field

[0001] This invention relates to the field of visual inspection technology, specifically to a visual inspection device and method for porcelain insulators. Background Technology

[0002] Porcelain insulators are electrical equipment insulation components made of electrical ceramics, primarily composed of high-purity alumina, zirconium oxide, and other materials. Their structure includes an iron cap, porcelain components, and steel feet, assembled using cement bonding. They possess high-temperature resistance, pressure resistance, and corrosion resistance, and are used for external insulation of high-voltage transmission lines and power station equipment.

[0003] In the prior art, patent number CN119246528B, entitled "A Visual Monitoring System for the Working Status of Insulators," includes: a discharge detection device that senses audio signals near the insulator ceramic component and emits a discharge abnormality signal when the audio signal contains audio components whose frequency is outside the reference discharge frequency range corresponding to the insulator ceramic component and whose amplitude exceeds the limit; and an intelligent analysis device that intelligently identifies whether there are spots on the glaze of the corresponding insulator ceramic component based on various visual data. This visual monitoring system for the working status of insulators is logically compact and widely applicable. Because the intelligent visual monitoring of whether there are spots on the surface of the insulator ceramic glaze is triggered only when an abnormal discharge sound is detected in the transmission line environment where the insulator is located, the pixel-level analysis precision improves the reliability and stability of the visual monitoring results, thereby avoiding the waste of a large amount of system power consumption and improving the recognition effect of the insulator's working status.

[0004] However, existing porcelain insulators require manual inspection from a high position, resulting in low inspection efficiency and placing operators at a dangerous height during inspection. Summary of the Invention

One end of the spring is connected to the end of the lifting ring 20, and the other end is connected to the inner wall of vertical rod 22. The spring in the insertion hole 21 exerts a pulling force on the lifting ring 20, causing the lifting ring 20 to insert into the insertion hole 21. A connecting rod is fixed to the surface of the lifting ring 20. A connecting rod 19 is attached to a second rope 23, which is inserted into the interior of a load-bearing rod 11.

The U-shaped rod 4 is moved to both sides of the insulator 3 by the drone. Under the gravity of the weighted ball 8, the U-shaped rod 4 rests on the outside of the insulator 3. After the drone is released, the swing ring 28 swings along the rotating ring 15 under the gravity. Because there is a notch at the bottom of the swing ring 28, the swing ring 28 moves to the outside of the cable 1. The elastic plate 2... The support plate 27 is used to support the swing ring 28, which swings along the rotating ring 15 and then supports the surface of the support plate 25. The swing ring 28 is in a vertical state. The first motor 12 drives the rotating shaft 14 to rotate. The surface of the rotating shaft 14 is provided with a gear 9, and the outside of the gear 9 is provided with a track 10. After the gear 9 rotates, it drives the track 10 to move. The track 10 supports the surface of the insulator 3, so that the U-shaped rod 4 can move on the surface of the insulator 3. The first visual inspection head 30 and the second visual inspection head 35 can perform visual inspection on the insulator 3. The second motor 33 drives the gear inside the housing 34 to rotate. The gear in the housing 34 meshes with the teeth on the surface of the ring groove 31, so that the moving ring 32 moves in the ring groove 31.

The U-shaped rod (4) is moved to both sides of the insulator (3) by the drone. Under the gravity of the weighted ball (8), the U-shaped rod (4) is placed on the outside of the insulator (3). Step 2: After releasing the lifting of the drone, the swing ring (28) swings along the rotating ring (15) under the action of gravity. Since there is a notch at the bottom of the swing ring (28), the swing ring (28) moves to the outside of the cable (1), and the elastic plate (26) supports the force plate (27), so that the swing ring (28) swings along the rotating ring (15) and supports the surface of the supporting plate (25). The swing ring (28) is in a vertical state. The first motor (12) drives the rotating shaft (14) to rotate. The surface of the rotating shaft (14) is provided with a gear (9), and the outside of the gear (9) is provided with a track (10). After the gear (9) rotates, it drives the track (10) to move. The track (10) supports the insulator. (3) The surface of the insulator allows the U-shaped rod (4) to move on the surface of the insulator (3). The first visual inspection head (30) and the second visual inspection head (35) can perform visual inspection on the insulator (3). The second motor (33) drives the gear inside the housing (34) to rotate. The gear in the housing (34) meshes with the teeth on the surface of the moving ring (32), causing the moving ring (32) to move in the ring groove (31). The first visual inspection head (30) and the second visual inspection head (35) move with the moving ring (32) to inspect the insulator (3). The insulator (3) can be visually inspected simply by using a drone to lift the inspection equipment to the outside of the insulator (3).
