Description

Technical Field

[0001] This utility model relates to the field of communication engineering technology, and in particular to a suspension insulator that prevents loosening. Background Technology

[0002] Suspension insulators are electrical devices used in power transmission lines, typically made of porcelain, glass, or composite materials. Their structure resembles a string of discs suspended between high-voltage power lines. Connecting them in series increases voltage withstand capability, primarily serving to support the conductors and insulate against voltage fluctuations. Suspension insulators possess high mechanical strength and excellent electrical insulation properties, capable of withstanding the weight of the power line, wind force, and other external stresses, while effectively preventing current leakage or short circuits.

[0003] In existing technologies, suspension insulators are generally installed at a high position, and the outer wall of suspension insulators lacks self-cleaning components. The accumulation of contaminants may cause conductive channels to form on the surface of the insulator, increasing leakage current and reducing insulation effect. In addition, it requires workers to climb frequently, and the cleaning process of suspension insulators is high-risk and time-consuming. Summary of the Invention

[0004] The purpose of this invention is to address the problems in the existing technology where suspension insulators are generally installed at a high position, lack self-cleaning components on the outer wall, and the accumulation of contaminants may lead to the formation of conductive channels on the surface of the insulator, increasing leakage current, reducing insulation effect, and requiring workers to frequently climb high, making the cleaning process of suspension insulators dangerous and time-consuming. Therefore, this invention proposes an anti-loosening suspension insulator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A suspension insulator designed to prevent loosening includes a center post with an installation hole at its bottom. A retaining ring is fixedly disposed on the bottom of the outer wall of the center post. Multiple insulating ceramic rings are movably sleeved on the center post above the retaining ring. A threaded post is fixedly disposed on the top of the center post, and an anti-loosening component is fixedly disposed on the top of the threaded post to tightly press the multiple insulating ceramic rings against the outer wall of the center post. A receiving ring groove is provided on the side of the retaining ring, and a self-cleaning component is disposed on the side of the receiving ring groove to self-clean the outer walls of the multiple insulating ceramic rings.

[0007] Optionally, the anti-loosening component includes a pressure cylinder, a threaded sleeve, and a rotating handle. The top of the pressure cylinder is fixedly connected to the threaded sleeve, and the inner diameter of the pressure cylinder is larger than the outer wall of the central column.

[0008] Optionally, the threaded sleeve is screwed into the outer wall of the threaded column, and the outer wall of the threaded sleeve is fixedly provided with rotating handles at equal intervals.

[0009] Optionally, the self-cleaning component includes a fixing ring, a vertical rod, and a driving cup. The fixing ring is movably sleeved inside the receiving ring groove, and extension rods are symmetrically fixed on both sides of the fixing ring.

[0010] Optionally, a drive cup is fixedly installed at the end of the extension rod, and a vertical plate is fixedly installed on the top of the extension rod on one side of the fixing ring by bolts, and a weight reduction groove is opened on the side of the vertical plate.

[0011] Optionally, the vertical plate has a serrated edge on one side near the multiple sets of insulating ceramic rings, and the serrated edge is attached to the side of the multiple sets of insulating ceramic rings.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. The main structure of this utility model includes a central column, and multiple insulating ceramic rings are commonly sleeved on the outer wall of the central column. The sides of the multiple insulating ceramic rings are provided with wind-powered self-cleaning components. The self-cleaning components can use the wind power at high altitudes to scrape away any debris that may be attached to the outer wall of the multiple insulating ceramic rings from time to time, so as to avoid the accumulation of pollutants that may form conductive channels on the surface of the insulator, increase leakage current, reduce insulation effect, and require workers to climb frequently. The cleaning process of suspension insulators is dangerous and time-consuming. Attached Figure Description

[0020] Reference Figure 1-3 A suspension insulator designed to prevent loosening includes a center post 3, with an installation hole at the bottom of the center post 3. A retaining ring 1 is fixedly installed on the bottom of the outer wall of the center post 3. Multiple insulating ceramic rings 8 are movably sleeved on the center post 3 above the retaining ring 1. A threaded post 7 is fixedly installed on the top of the center post 3. An anti-loosening component is fixedly installed on the top of the threaded post 7 to tightly press the multiple insulating ceramic rings 8 against the outer wall of the center post 3. The inner diameter of the retaining ring 1 is smaller than the outer diameter of the insulating ceramic rings 8.

[0021] The support ring 1 has a receiving ring groove 2 on its side. The receiving ring groove 2 is provided with a self-cleaning component that self-cleans the outer wall of multiple insulating ceramic rings 8. The anti-loosening component includes a pressure cylinder 6, a threaded sleeve 4, and a rotating handle 5. The top of the pressure cylinder 6 is fixedly connected to the threaded sleeve 4. The inner diameter of the pressure cylinder 6 is larger than the outer wall of the central column 3. The threaded sleeve 4 is screwed into the outer wall of the threaded column 7. The rotating handle 5 is fixedly provided at equal intervals on the outer wall of the threaded sleeve 4 to facilitate the user to rotate the threaded sleeve 4.

[0022] The self-cleaning component includes a fixing ring 13, a vertical rod 12, and a drive cup 15. The fixing ring 13 is movably fitted inside the receiving ring groove 2. An extension rod 14 is symmetrically fixed on both sides of the fixing ring 13. The drive cup 15 is fixedly fixed at the end of the extension rod 14. The drive cup 15 is hemispherical. A vertical plate 11 is bolted to the top of the extension rod 14 on one side of the fixing ring 13. A weight-reducing groove 9 is opened on the side of the vertical plate 11. A fitting serration 10 is opened on the side of the vertical plate 11 near the multiple sets of insulating ceramic rings 8. The fitting serration 10 fits into the side of the multiple sets of insulating ceramic rings 8.

[0023] It should be added that a threaded hole is additionally provided at the center of the top of the threaded post 7, which facilitates the connection of multiple suspension insulators in series.

[0024] The specific implementation steps and principles of this utility model are as follows:

[0025] When installing a single suspension insulator, workers manually place multiple insulating porcelain rings 8 onto the outer wall of the central column 3. Finally, they manually screw the threaded sleeve 4 into the outer wall of the threaded column 7 until the pressing cylinder 6 presses the multiple insulating porcelain rings 8 down onto the top of the supporting ring 1. Finally, the vertical rod 12 is fixed to the top of the extension rod 14, so that the fitting saw teeth 10 fit against the side walls of the multiple insulating porcelain rings 8. When the driving wind cup 15 is blown by the wind, the fixing ring 13 rotates around the receiving ring groove 2, and the fitting saw teeth 10 on the side of the vertical rod 12 scrape the scale off the outer walls of the multiple insulating porcelain rings 8.
