Description

Technical Field

[0001] The present invention relates to the field of glass insulator maintenance, in particular to a glass insulator maintenance device. Background Art

[0002] Glass insulators are insulating components used in high-voltage and ultra-high-voltage transmission lines. They primarily consist of two parts: a glass element and metal accessories. The glass element, the core component, is typically made of tempered glass produced through a special process. This glass possesses high mechanical strength and electrical insulation properties. Its shape is typically disc-shaped or bell-shaped. In transmission lines, these shapes help increase creepage distance and effectively prevent current leakage along the insulator surface. Metal accessories typically include steel legs and iron caps, which are mounted at the top and bottom of the glass element. These metal accessories connect the glass insulator to the transmission line and tower, ensuring a stable connection of the entire transmission line. They also effectively transfer and distribute mechanical loads, ensuring proper operation of the line under various environmental conditions. Currently, glass insulators require regular maintenance and inspection to ensure their physical properties and safety.

[0003] In contrast, Chinese invention publication CN111632891A discloses a high-voltage line insulator cleaning system and method that utilizes a curved cleaning brush to clean and maintain glass insulators. Currently, most existing maintenance equipment utilizes a high-voltage medium to clean and maintain insulators. However, because most glass insulators are made of tempered glass, the glass components of these insulators are characterized by surface compressive stress and internal tensile stress. These stresses are generated by temperature fluctuations during glass processing. When a glass component, heated to its softening temperature (760-780°C), rapidly cools, the surface layer contracts due to the quenching force, while the internal temperature remains high and in an expanded state, hindering its contraction and leaving compressive stress within the surface layer. Subsequently, as the internal temperature drops, it begins to contract, but the surface layer has already hardened, hindering its internal contraction and generating tensile stress. These two stresses remain evenly distributed within the glass component until it cools completely and the temperature gradient disappears, constituting permanent stresses. Once the balance between compressive stress and tensile stress in the glass parts of glass insulators is destroyed, cracks will quickly appear under the action of stress, causing the glass parts to shatter, that is, self-explosion. Currently, glass insulators are used in multiple stacks, which will not destroy the stress balance under normal circumstances. However, in external wind, rain and snow environments, shaking and temperature changes may cause instantaneous cracking. The purpose of maintaining glass insulators is to find and solve problems. Therefore, when maintenance is needed, it is also necessary to effectively power them to release stress and quickly and effectively detect unqualified products. Summary of the Invention

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] An embodiment of a glass insulator maintenance device of the present invention is as follows Figures 1 to 11As shown, it includes a power mechanism 4 for installation and fixation, a toggle mechanism 8 for toggling the glass insulator 5 to release its stress, and a bottom fixing mechanism 6 for cooperating with the toggle mechanism 8 to move the device. The top of the power mechanism 4 is hoisted and moved by the drone 1. The bottom of the drone 1 is connected to a traction assembly 2. The traction assembly 2 is connected to the hanger 42 of the power mechanism 4 through a locking assembly 3. Two bottom fixing mechanisms 6 are provided and symmetrically installed at both ends of the power mechanism 4 near the lower side. A cleaning and detection mechanism 7 for cleaning and maintaining the power mechanism 4 is installed on the upper side of each bottom fixing mechanism 6. The toggle mechanism 8 is installed on the power mechanism 4.

[0033] like Figure 2 As shown, the power mechanism 4 includes a top box 41, and side limit columns 43 are symmetrically provided at both ends of the top box 41. The side limit columns 43, the search, cleaning and detection mechanism 7 and the bottom fixing mechanism 6 are fixedly installed on the side limit columns 43 by bolts;

[0034] like Figure 3-9 As shown, the toggle mechanism 8 is installed on the bottom end surface of the top box 41, and the toggle mechanism 8 includes a top toggle assembly 84, an angle is set between the top toggle assembly 84 and the travel direction of the power mechanism 4, the outside of the top toggle assembly 84 is driven by the power assembly, and the upper end of the top toggle assembly 84 is connected to the top mounting frame 81 through the adjustment assembly, and the top toggle assembly 84 includes a toggle track 841, a toggle block 842, and an outer frame 843. The toggle track 841 is wrapped and arranged on the outside of the outer frame 843, and the toggle track 841 is connected to the power assembly through a gear. Several groups of toggle blocks 842 are evenly arranged on the toggle track 841, and the adjacent toggle blocks 842 are connected by strain gauges 8421, and the even-numbered toggle blocks 842 in the second group are connected to the even-numbered toggle blocks 842 in the first group, and the odd-numbered toggle blocks 842 in the second group are connected to the odd-numbered toggle blocks 842 in the third group (as shown in FIG. Figure 9 As shown, in Figure 9 As shown in the dotted box in the figure, the groups are numbered a, b, and c from left to right, and 1, 2, 3, and 4 from top to bottom, with odd numbers being 1 and 3 and even numbers being 2 and 4. The toggle blocks 842 at the even-numbered positions in the b column are connected to the toggle blocks 842 at the even-numbered positions in the a column via strain gauges 8421, and the toggle blocks 842 at the odd-numbered positions in the b column are connected to the toggle blocks 842 at the odd-numbered positions in the c column via strain gauges 8421, and so on). As a result, when the toggle blocks 842 come into contact with the glass insulator during movement, the pressure from the top toggle assembly 84 can cause the strain gauges 8421 to cause the two toggle blocks 842 to lock inward, thereby clamping the glass insulator. The glass insulator is then toggled and rotated by the rotation of the toggle track 841.

[0035] In this embodiment, the adjustment assembly of the top toggle assembly 84 includes a top buffer assembly 85, and the top toggle assembly 84 is connected to the top sliding frame 83 through the top buffer assembly 85. The top sliding frame 83 is slidably connected to the top mounting frame 81, and the top mounting frame 81 is located on the upper side of the top toggle assembly 84. The middle part of the top toggle assembly 84 is movably connected to the top mounting frame 81 through a top swing arm 86. A top cylinder 82 is installed on the top of the top mounting frame 81, and the movable end of the top cylinder 82 is connected to the top sliding frame 83. The top cylinder 82 can support the top toggle assembly 84 to move downward to press the glass insulator.

[0036] In this embodiment, the top buffer assembly 85 includes a telescopic rod 851, a support sleeve 852, and a support spring 853. The telescopic rod 851 is connected to the top sliding frame 83 through a pin shaft. The end of the telescopic rod 851 away from the top sliding frame 83 is slidably connected to the support sleeve 852. A support spring 853 is arranged between the telescopic rod 851 and the support sleeve 852. The support sleeve 852 is slidably connected to the outer frame 843 through a connecting pin 854. The top buffer assembly 85 is used to change the power of the top cylinder 82 into an elastic support and transmit it to the top toggle assembly 84, thereby avoiding the pressure of the top toggle assembly 84 and the toggle track 841 being too rigid, thereby causing a rigid impact on the glass insulator and causing damage.

[0037] In this embodiment, if Figure 8 As shown, the connecting pin 854 is connected to the folding frame 855 located inside the outer frame 843. The folding frame 855 is a V-shaped frame. The opening angle of the folding frame 855 is 120°. Several pulleys supporting the shifting track 841 are arranged inside the outer frame 843. The two pulleys located in the middle position of the lower side are connected to the folding frame 855 through a pin shaft, and the center point of the folding frame 855 and the point on the side away from the connecting pin 854 are connected to the pulley.

[0038] In this embodiment, the bottom fixing mechanism 6 includes a bottom mounting frame 61. The two ends of the bottom mounting frame 61 are connected to the slider via flanges. The slider is connected to the side limit column 43 and the bottom mounting frame 61 via bolts. The bottom mounting frame 61 can adjust the flange angle so that the bottom fixing mechanism 6 can adapt to glass insulators 5 of different specifications.

[0039] In the embodiment, the bottom cylinder 62 is installed on the bottom mounting frame 61, the fixed end of the bottom cylinder 62 is connected to the bottom mounting frame 61 through a triangular seat, the movable end of the bottom cylinder 62 is connected to the bottom sliding frame 64, the bottom sliding frame 64 is connected to the bottom sliding groove 65 on the bottom mounting frame 61 through a pin shaft, the bottom buffer assembly 66 is installed outside the bottom sliding frame 64, the traveling assembly 63 is connected to one end of the bottom buffer assembly 66 away from the bottom sliding frame 64, the traveling assembly 63 is further matched with the bottom mounting frame 61 through two bottom swing arms 67, the traveling assembly 63 is a track traveling structure, the adjusting part of the bottom fixing mechanism 6 and the adjusting part of the poking mechanism 8 are basically the same, and both are used to ensure that the glass insulator is effectively fixed after being matched, and the buffer is used to avoid damage to the glass insulator.

[0040] In the embodiment, the air pump is installed at the center of the top box 41, the cleaning and detecting mechanism 7 includes a detection frame 71, two detection frames 71 are symmetrically installed at the lower ends of the two sides of the top box 41, a plurality of high-pressure air nozzles 72 are uniformly installed on the detection frame 71 corresponding to the end face of the glass insulator 5, and the ultrasonic detector 73 is installed on the detection frame 71 corresponding to the lower part of the poking mechanism 8.

[0041] In the embodiment, the material of the poking track 841 is rubber, and the poking block 842 is a metal frame wrapped with rubber on the outside.

[0042] In the embodiment, the inner side of the poking track 841 is a synchronous belt structure, and a synchronous wheel is matched with the inner side of the poking track 841, and the synchronous wheel is connected to the outer frame 843 through a bearing.

[0043] In the embodiment, the angle between the top poking assembly 84 and the traveling direction of the power mechanism 4 is 45°.

[0044] The working principle is as follows: according to the size of the glass insulator to be maintained, the position of the bottom fixing mechanism 6 on the side limiting column 43 is adjusted first, so that the glass insulator can be clamped when the two bottom fixing mechanisms 6 and the poking mechanism 8 are tightened;

[0045] The unmanned aerial vehicle 1 is started to hoist the power mechanism 4 to the upper side of the glass insulator, at this time, the bottom cylinder 62 and the traveling assembly 63 are in the retracted state, and will not damage the glass insulator when being clamped downward on the outside of the glass insulator, after being lowered to the appropriate position, the bottom cylinder 62 is started to make the two traveling assemblies 63 cooperate with the top poking assembly 84 to form a triangular structure, so as to sleeve the glass insulator;

[0046] Start the motor of the top toggle assembly 84 to rotate the toggle track 841, and at the same time start the motor of the travel assembly 63 to start the travel assembly 63. In this solution, the angle between the top toggle assembly 84 and the travel direction is 45 degrees, so the travel speed of the top toggle assembly 84 is 1.4 times that of the travel assembly 63. At this time, because the top cylinder 82 provides support for the top toggle assembly 84, and the elastic compression of the top buffer assembly 85 is used to ensure that the toggle track 841 is pressed against the end face of the glass insulator, the friction force of the inclined surface is used to toggle the glass insulator, so that the device During the journey, the glass insulator rotates. When the glass insulator rotates, the stress accumulated due to the long-term squeezing and fitting between the glass insulators is released. If the quality of the glass insulator is good and there are no internal micro cracks or cracks caused by the external environment, the high-pressure air nozzle 72 and the ultrasonic detector 73 are activated while the glass insulator rotates to clean and maintain the area around the glass insulator and to inspect the surface for flaws. If the stress accumulates for too long and cracks occur after rotation, it means that it needs to be replaced, and the ultrasonic detector 73 is used to scan and mark it.

[0047] At the same time, when the toggle rotation is performed, the size of the equipment changes during operation due to the gap between the glass insulators. The top buffer assembly 85 in this solution provides elastic support and is transmitted to the folding frame 855 through the connecting pin 854. The folding frame 855 drives the toggle track 841 on the corresponding side of the glass insulator to produce an outward bulge. At the same time, the outward bulge is also in an elastic state, so that the toggle block 842 can be pre-opened before contacting the glass insulator next time. After the toggle block 842 contacts the glass insulator, the toggle block 842 will shrink, causing the strain gauge 8421 to be subjected to force. Because the adjacent toggle blocks 842 are connected by the strain gauge 8421, and the even-numbered toggle blocks 842 in the second group are connected to the even-numbered toggle blocks 842 in the first group, and the odd-numbered toggle blocks 842 in the second group are connected to the odd-numbered toggle blocks 842 in the third group, the strain gauge 8421 will drive the toggle block 842 to produce an inward buckling state (such as Figure 10-11 ), ensuring the friction between the toggle block 842 and the glass insulator, thereby ensuring that the toggle block 842 can drive the glass insulator to rotate when it moves.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
