Description

Technical Field

[0001] The present invention relates to the technical field of ceramic insulators, and more specifically to a ceramic insulator for ultra-high voltage power transmission for connecting thick cables. Background Art

[0002] Ceramic insulators, as insulators that play multiple roles of electrical insulation, mechanical connection, and bearing the load of conductors on high-voltage power transmission and transformation lines, are of special importance in high-voltage and ultra-high voltage power transmission equipment systems; devices that can withstand voltage and mechanical stress and are installed between conductors at different potentials or between conductors and grounding components. There are many types of insulators with different shapes. Although the structures and outer shapes of different types of insulators vary greatly, they are all composed of two major parts: insulating parts and connecting fittings;

[0003] However, when the existing insulators are installed, collisions are likely to occur between multiple insulating parts, resulting in the breakage or cracking of the insulating parts, which easily leads to waste of insulating parts. Therefore, this application proposes a ceramic insulator that can avoid collisions between multiple insulating parts. Summary of the Invention

[0004] To overcome the deficiencies of the prior art, the present invention provides a ceramic insulator for ultra-high voltage power transmission for connecting thick cables, which can avoid collisions between multiple insulating parts.

[0005] The technical solution adopted by the present invention to solve its technical problems is as follows:

[0006] A ceramic insulator for ultra-high voltage power transmission for connecting thick cables includes a plurality of discs with inner sleeves formed in the middle, a central shaft that can penetrate into the inner sleeve and contact the inner wall surface of the inner sleeve, and rubber sleeves distributed between adjacent two inner sleeves and sleeved on the central shaft.

[0007] Preferably, a plurality of inclined teeth inclined from the outside to the inside are formed on the upper surface of the disc.

[0008] Preferably, it further includes two grooves provided at the upper and lower ends of the central shaft, two rotating rings respectively rotating in the two grooves, and a scraping blade fixed on the two rotating rings and in line contact with the surfaces of the plurality of discs. A lever is fixed to the upper end of the scraping blade.

[0020] By observing Figures 1 to 4 an exemplary working process for firmly fixing the disc 01 can be obtained according to the content shown in the figure as follows:

[0021] A ceramic insulator for ultra-high voltage power transmission for connecting thick cables includes a plurality of discs 01 with inner sleeves 02 formed in the middle, a central shaft 05 that can penetrate into the inner sleeve 02, the central shaft 05 is in contact with the inner wall surface of the inner sleeve 02, and rubber sleeves 06 distributed between two adjacent inner sleeves 02 and sleeved on the central shaft 05; when manufacturing the insulator, only need to sleeve the inner sleeve 02 on the disc 01 onto the central shaft 05, then sleeve a rubber sleeve 06 on the central shaft 05, and utilize the elastic deformation of the rubber sleeve 06 itself to make the rubber sleeve 06 tightly sleeved on the central shaft 05 so that it will not move under normal conditions, and then sleeve another disc 01 on the central shaft 05 in the above manner, so as to finally realize that the multiple inner sleeves 02 are restricted by the rubber sleeve 06, avoiding collision between the multiple inner sleeves 02 and causing damage, and at the same time using the frictional force generated by the contact between the multiple inner sleeves 02 and the rubber sleeve 06 to prevent the multiple inner sleeves 02 from rotating randomly on the central shaft 05.

[0022] By observing Figures 1 to 4 an exemplary working process for facilitating the operator to hold or step on can be obtained according to the content shown in the figure as follows:

[0023] The upper surface of the disc 01 is formed with a plurality of oblique teeth 03 inclined from outside to inside; when the operator holds the disc 01, the plurality of oblique teeth 03 can increase the friction between the disc 01 and the operator's hand, thereby preventing the disc 01 from falling off the operator's hand and causing damage, and at the same time making it easier for the operator to climb from the disc 01 to the position of the cable for operation; when the operator steps on the disc 01, the plurality of oblique teeth 03 can be used to increase the friction so that the operator's soles can step on the disc 01 more safely, avoiding the danger of slipping.

[0024] By observation Figures 1 to 4 An exemplary working process that can be obtained to reduce the overall mass according to what is shown in the figure is:

[0025] The inside of the disc 01 is a hollow structure, which can reduce the mass of a single disc 01, thereby reducing the overall mass of the insulator.

[0026] By observation Figure 4 and Figure 5 According to the contents shown in the figure, an exemplary working process for preventing water accumulation on the surface of the disk 01 is:

[0027] When it rains, in order to avoid water accumulation inside the multiple bevel teeth 03, the multiple bevel teeth 03 on the same disc 01 in the present application are formed with multiple openings 04 extending outward from the center of the disc 01; rainwater inside the multiple bevel teeth 03 can flow out along the multiple openings 04, thereby avoiding rainwater accumulation inside the multiple bevel teeth 03 and causing safety hazards.

[0028] By observation Figure 1 and Figure 6 According to the contents shown in the figure, an exemplary working process of cleaning the disc 01 is:

[0029] The insulator further comprises two grooves 08 arranged at the upper and lower ends of the central axis 05, two rotating rings 09 respectively rotating in the two grooves 08, and scrapers 11 fixed on the two rotating rings 09 and in line contact with the surfaces of the plurality of disks 01, and a lever 10 is fixed on the upper end of the scrapers 11; when the insulator is inspected and repaired, the scrapers 11 can be driven by the lever 10 to make the two rotating rings 09 rotate around the central axis 05 in the two grooves 08 at the same time, so that the scrapers 11 can clean the surface of the disk 01, and timely clean the snow and impurities on the disk 01, as well as the feces excreted by birds, etc.

[0030] By observation Figure 1 and Figure 10 According to the content shown in the figure, an exemplary working process of driving away birds is:

[0031] The described wiper blade 11 is evenly distributed with whistles 12 that can emit sounds when encountering flowing air; when the flowing air passes through the whistles 12, sounds can be generated, thereby scaring the surrounding birds, driving the birds away in time, and preventing the birds from staying on the insulator and causing damage to the insulator or excreting feces on the insulator.

[0032] By observing Figures 1 to 7 An exemplary working process of cleaning itself using wind energy can be obtained according to the content shown in the figure:

[0033] The insulator also includes two rotating sleeves 13 respectively fixed on two rotating rings 09, and a plurality of blades are evenly distributed along the axis of each rotating sleeve 13; when encountering windy weather, the wind can push the plurality of blades to drive the rotating sleeve 13 to drive the rotating ring 09 to rotate. When the rotating ring 09 rotates, it can drive the wiper blade 11 to rotate around the plurality of discs 01 to clean the surfaces of the plurality of discs 01. At the same time, the rotation of the wiper blade 11 is used to make the whistle 12 make a sound;

[0034] At the same time, the effect of the wind can be utilized to make the wiper blade 11 clean the plurality of discs 01 irregularly. By the rotational movement of the wiper blade 11 between two adjacent discs 01, it is avoided that birds build nests between two adjacent discs 01, thereby further ensuring the cleanliness of the insulator itself.

[0035] By observing Figures 1 to 8 An exemplary working process of protecting the operator can be obtained according to the content shown in the figure:

[0036] The insulator also includes two baffle plates 07 fixed at the upper and lower ends of the central axis 05, and a plurality of vertical rods 18 are evenly fixed on each baffle plate 07 along the axis of the central axis 05; when the operator repairs the insulator, the baffle plates 07 and the plurality of vertical rods 18 can be used to prevent the operator's hands from contacting the rotating plurality of blades, thereby avoiding damage to the operator's hands during the rotation of the plurality of blades. At the same time, it also prevents birds from approaching the plurality of blades and avoids the plurality of blades from injuring the birds, thereby also playing a protective role for the birds.

[0037] By observing Figure 9 and Figure 10 An exemplary working process of increasing the range of driving away birds can be obtained according to the content shown in the figure:

[0038] The insulator further includes a plurality of connecting rods 14 bolted to the wiper blade 11, a side rod 15 rotatable on the plurality of connecting rods 14, and a handle 16 fixed to the side rod 15; after the insulator is installed, the bolt can be loosened, and then by rotating the plurality of connecting rods 14, the plurality of connecting rods 14 can jointly support the movement of the side rod 15, so as to change the distance between the side rod 15 and the wiper blade 11. Finally, by tightening the bolt, the plurality of connecting rods 14 can be fixed, thus fixing the position of the side rod 15. When the wiper blade 11 rotates, it can drive the side rod 15 to rotate to change the range of driving away birds, so as to prevent birds from approaching the insulator;

[0039] At the same time, two spherical balls are formed at both the upper and lower ends of the side rod 15; the visual area can be increased through the two spherical balls, and colors can be sprayed on the two spherical balls, so that birds can observe the two spherical balls in time and become alert to dodge in time, avoiding being injured by the two spherical balls.
