Description

Technical Field

[0001] This invention belongs to the field of porcelain insulator testing, specifically a smart detection device and method for the pollution spectrum of porcelain insulators. Background Technology

[0002] During long-term operation of power lines, the surface of porcelain insulator skirts continuously accumulates a complex mixture of contaminants, including soluble salts, inert ash, industrial oil, and dust. Accurate, efficient, and all-weather detection of this surface contamination, precisely determining its composition, thickness, and level, is a core technological aspect for ensuring the safe and stable operation of power systems. With the iterative upgrades of new material spectral detection technology, non-destructive testing methods based on spectral feature recognition have become the preferred technology for new material performance testing, surface defect identification, and dielectric composition identification. This represents an advanced and preferred technological direction in the current field of new material testing, compared to traditional methods. The integrated physical and chemical testing and conventional imaging testing technologies possess core advantages such as non-contact, high precision, simultaneous multi-parameter detection, non-destructive testing, and wide adaptability. They are widely used in scenarios requiring precise detection of the surface condition of insulating materials and composite materials. Among these, the pollution spectral detection camera is a new type of intelligent detection device developed based on the principle of high-spectral fine-dispersive imaging. It perfectly meets the needs of refined and intelligent detection of pollution on the surface of porcelain insulator skirts. During use, multiple pollution spectral detection camera arrays need to be set up around the circumference of the porcelain insulator skirts to achieve complete pollution detection on the skirt surface. However, the following shortcomings still exist: During testing, it is difficult to install the equipment coaxially with the porcelain insulator, and it is also inconvenient to achieve longitudinal displacement of the pollution spectrum detection camera array after installation in order to detect pollution on the skirts at different heights. Consequently, it is inconvenient to install the equipment on the already installed porcelain insulator, making the testing difficult. Summary of the Invention

The limiting rod 2534 on the lifting plate 2533 is inserted into the outer arc groove 247 on the outer side wall of the lifting arc plate 246. The pneumatic telescopic corrugated tube 2532 is inflated with air, which pushes the two lifting arc plates 246 upward, so that the pollution spectrum detection camera 248 in the array can be moved to the position corresponding to the umbrella skirt of different heights for convenient detection.

[0023] Depend on Figure 8 The positioning component 26 includes a fixed cylinder 261 fixedly installed at the end of the fixed semi-ring plate 21. A positioning rod 262 is movably installed inside the fixed cylinder 261. The positioning rod 262 is inserted into the positioning groove 249. A spring 263 is fixedly installed at the end of the positioning rod 262 away from the fixed semi-ring plate 21. One end of the spring 263 is fixedly connected to the inner wall of the end of the fixed cylinder 261. A pull rod 264 is fixedly installed at the end of the positioning rod 262 away from the fixed semi-ring plate 21. By inserting the positioning rod 262 into the positioning groove 249, the original state of the equipment is positioned and fixed, and the various structures of the equipment are returned to their original positions after the equipment is vented.

[0024] Working principle: When in use, the scissor opening and closing mechanism 1 drives the two equipment installation mechanisms 2 to open outward, and the equipment is set outside the porcelain insulator that needs to be tested for pollution. Then, the scissor opening and closing mechanism 1 causes the two equipment installation mechanisms 2 to rotate, so that the two complete rings composed of two fixed half ring plates 21 correspond to the two ends of the core rod of the porcelain insulator respectively. The staff needs to carry an air pump with two output pipes. The ends of the two output pipes are connected to the inflation pipes 255 on the two connecting pipes 254 respectively. Then, the pull rod 264 is pulled upward to disengage the positioning rod 262 from the positioning groove 249. Then, the following two steps are performed sequentially: First, open the first valve 256 on the two connecting pipes 254, turn on the air pump, and then input air into each fixed box 231 through the arc pipe 251 and the connecting straight pipe 252, which generates pressure on the piston block 235 toward the mandrel side, thereby pushing each sliding plate 233 to move toward the mandrel side. The two fixed semi-circular plates 21 are combined to form a complete ring, so that the second tooth grooves 243 on the two top ring grooves 242 are tightly, evenly and continuously on the complete ring. The first tooth groove 237 on the inner side of the sliding plate 233 is meshed with the first gear 239, and the second gear 2310, which is coaxially set on the rotating shaft 238 with each first gear 239, is meshed with the second tooth groove 243, so that each sliding plate 233 moves synchronously until the clamping head 234 at the end of each sliding plate 233 is tightly clamped against the outer wall of the core rod, and the equipment is coaxially installed on the outside of the porcelain insulator. Simultaneously, when each of the second gears 2310 rotates synchronously, the second tooth groove 243 drives the complete ring rotation of the two annular slide plates 241, so that both annular slide plates 241 enter the two fixed semi-annular plates 21, thereby achieving self-locking of the two equipment installation mechanisms 2. The self-locking principle is that the rotational opening trajectory of the two equipment installation mechanisms 2 is offset from the movement trajectory of the annular slide plates 241 in the semi-annular slide groove 22, thereby achieving self-locking. After being fixed, the first valve 256 is closed.

[0025] Then, the second valves 257 on the two connecting pipes 254 are opened, whereby the plug block 2411 on one of the lifting arc plates 246 is inserted into the plug groove 2410 at the end of the other lifting arc plate 246, so that the two lifting arc plates 246 are combined to form a whole, and the limiting rods 2534 on the two lifting plates 2533 are inserted into the outer arc groove 247 on the outer side wall of the lifting arc plate 246. The air pump is turned on, pumping air from the U-shaped tube 2535 into the pneumatic telescopic bellows 2532, causing the pneumatic telescopic bellows 2532 to open. This pushes the lifting plate 2533 upward, which in turn pushes the two lifting arc plates 246 upward synchronously via the limit rod 2534. This, in turn, drives multiple pollution spectrum detection cameras 248, which are set at equal angles, to move upward. The pollution spectrum detection cameras 248 are set at a downward tilt. When they move to above the first skirt of the porcelain insulator from bottom to top, the pollution spectrum detection cameras 248 are aligned with the upper surface of the skirt. The multiple pollution spectrum detection cameras 248 arranged in a ring array each correspond to a certain range, thereby achieving complete detection of the 360-degree ring area of ​​the skirt. When the 248 pollution spectral detection cameras perform non-contact pollution detection on the surface of porcelain insulator skirts, the equipment collects the visible to near-infrared reflectance spectrum of the skirt area. Relying on the unique spectral fingerprints of various pollution media, it distinguishes the porcelain matrix, soluble salts, dust and dirt, etc. After standard white board reflectance correction to eliminate interference caused by lighting and shooting angle, it extracts the complete spectral curve of each pixel and matches it with the pre-set pollution sample spectral database. Combined with the algorithm, it inverts the equivalent salt density and ash density values ​​of the skirt surface and simultaneously generates a visual heat map of the pollution distribution of the insulator skirt. It can accurately locate the degree of pollution in easily accumulated areas such as the edges and grooves of the skirt. It realizes integrated quantitative intelligent detection of the pollution composition, pollution level and spatial distribution of the porcelain insulator surface under the condition of no power outage. This non-destructive testing method based on spectral feature recognition has become the preferred technology for new material performance testing, surface defect and medium composition identification. After the bottom umbrella skirt is inspected, the second valve 257 is opened to continue inflating the pneumatic telescopic bellows 2532, so that the pollution spectrum detection camera 248 can move to the position above each umbrella skirt in turn, thereby realizing intelligent pollution spectrum detection on the surface of each umbrella skirt. In addition, during use, it can detect the installed porcelain insulators without disassembling them for inspection.
