Description

Technical Field

[0001] This invention relates to the field of insulator technology, specifically to a suspension-type wind-resistant porcelain insulator. Background Technology

[0002] Suspension insulators are composed of insulating components (such as porcelain components and glass components) and metal accessories (such as steel feet and iron caps) assembled by gluing or mechanical clamping. They are mainly used to suspend conductors in overhead transmission lines and to achieve electrical insulation between the tower and the conductor. According to their structure, they can be divided into two types: disc type and rod type.

[0003] In the Chinese patent with publication number CN118711917B entitled "A Suspension Porcelain Insulator with Steel Cap Connection Stability", the telescopic rod of this patent can play a role in buffering and supporting, preventing the two insulator bodies from getting close to each other and colliding. When blown by the wind, the wind can push the insulating sweeping plate to rotate on the upper surface of the corresponding insulator body, cleaning the upper surface of the insulator body and reducing the accumulation of pollutants. When high-voltage lines are blown by strong winds, the insulators will swing. During this swinging motion, the insulators will directly wear down the connectors between the insulators and the high-voltage lines, damaging the galvanized protective layer on the connectors' surface. This reduces the connectors' corrosion resistance and consequently shortens their service life. The telescopic rod in this patent can only buffer the tension in the vertical direction and cannot buffer the lateral swinging force, resulting in poor protection for the insulators and connectors. Furthermore, when an insulator is damaged and needs to be replaced, existing technologies require replacing the entire insulator, which is environmentally unfriendly. Summary of the Invention

[0004] This invention provides a suspension-type wind-resistant porcelain insulator, which can effectively solve the problems mentioned in the background art where, when a high-voltage line is blown by strong winds, the insulator will swing, and the swinging of the insulator will directly wear down the connection between the insulator and the high-voltage line, reducing the service life of the connection. The existing technology has poor protection effect on the insulator and connection. When the insulator is damaged and needs to be replaced, the existing technology requires the replacement of the entire insulator, which is not environmentally friendly.

[0009] According to the above technical solution, a hemispherical groove is provided on the bottom inner side of the fixing clamp, the connecting ball is located inside the two hemispherical grooves, and a connecting groove is provided on the top inner side of the fixing clamp.

[0010] According to the above technical solution, a bird-repelling whistle is connected to the outside of the fixing clip, two adjacent fixing clips are connected by fixing bolts, and a connecting piece is connected to the bottom of the connecting rod, the connecting piece being embedded in the adjacent connecting groove.

[0011] According to the above technical solution, convenient suspension components are provided at the top and bottom of the three insulator bodies, and the convenient suspension components include top suspension seats; The top of the insulator body located at the very top is connected to a top suspension seat, the bottom of the top suspension seat is connected to a top suspension plate, the top suspension plate is embedded in the adjacent connecting groove, and the top of the top suspension seat is connected to a suspension crossbar via a suspension rod. The top of the suspension crossbar is provided with a lifting plate, and the middle of the lifting plate has an opening. I-shaped sliders are slidably connected to both ends of the opening. Clamping ears are connected to the bottom of the I-shaped sliders. Clamping cylinders are connected to one side of the clamping ears. The two clamping cylinders are respectively sleeved on both ends of the suspension crossbar. Fixed ears are connected to both ends of the bottom of the lifting plate. The fixed ears and clamping ears are connected by clamping springs.

[0012] According to the above technical solution, the bottom of the insulator body is connected to two suspension clips. The top and bottom of the suspension clips are provided with suspension grooves. The connecting piece at the bottom is embedded in the top suspension groove.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Equipped with wind-resistant protection components, the insulator body has a conical groove inside. When the insulator body swings in strong winds, the impact kinetic energy is converted into elastic potential energy through the elastic deformation of the arc-shaped spring, buffer spring and rubber plug, and then the energy is slowly released to buffer the impact and buffer the lateral swing force. The arc-shaped spring and rubber plug separate the connecting rod from the insulator body, so that the connecting rod does not collide with the insulator body, avoiding friction between the insulator body and the connecting rod, protecting the galvanized layer on the surface of the connecting rod, and improving the service life of the connector. Moreover, the arc-shaped spring is evenly distributed on the outside of the connecting rod, which can fully protect the connecting rod regardless of the wind direction, and the protection effect is good. When the series-connected insulators are subjected to a sudden tensile force, the annular spring and rubber sheet will undergo elastic deformation under the action of the tensile force, converting the impact kinetic energy into elastic potential energy. This protects the connectors between each insulator body in the vertical direction, further improving the service life of the connectors. In addition, the annular spring and sealing disc can seal the opening at the bottom of the conical groove, preventing external dust from entering the conical groove and avoiding dust corrosion of the connectors inside the conical groove, thus extending the service life of the connectors. When the insulator swings, the connecting ball rotates smoothly between the two hemispherical slots. Under the action of gravity, the series-connected insulators can quickly return to a vertical state, ensuring the stability of the conductor's hoisting, good suspension and fixing effect of the conductor, and good wind resistance. When the ceramic of the insulator body needs to be replaced, the arc-shaped spring is pulled by the sealing disc under the connection of the steel wire rope, so that the arc-shaped spring is contracted. When the diameter of the contracted arc-shaped spring is smaller than the opening diameter of the bottom of the conical groove, the connecting rod and the arc-shaped spring are moved out as a whole. After being moved out, the arc-shaped spring is squeezed by the conical groove, so that the arc-shaped spring is completely inserted into the new insulator body, realizing the reuse of the connecting parts and making it more environmentally friendly.

[0016] 2. Equipped with a convenient suspension assembly, during insulator installation, by pulling the I-shaped slider inside the movable opening, the two ends of the suspension crossbar can be quickly inserted into the two clamping cylinders. The suspension crossbar is clamped and fixed by the elastic force of the clamping springs. During subsequent insulator maintenance and replacement, the insulator can be disassembled and installed by pulling the I-shaped slider, which is convenient and quick. The top suspension seat is connected to the fixed clamp via a top suspension plate. The bottom suspension seat has a bottom suspension plate connected to its top, which is embedded in the bottom suspension groove. When the two suspension clamps are separated, the bottom insulator can be separated from the bottom suspension seat. The bottom of the bottom suspension seat is connected to a fixed clamp via a suspension rod. The fixed clamp and the movable clamp can hold the conductor. Together with the hoisting of the insulator, the conductor can be suspended and fixed. The number of insulators can be flexibly installed according to the requirements, and it has a wide range of applications.

[0017] In summary, in the wind-resistant protection component, adjacent fixing clips are connected by fixing bolts, and the connecting plate at the bottom of one insulator is embedded in the connecting groove at the top of another insulator, realizing the end-to-end connection between each insulator. In the convenient suspension component, the top suspension seat is connected to the fixing clip through the top suspension plate, and the bottom suspension seat is connected to the suspension clip through the bottom suspension plate. The connecting parts in both components can be quickly disassembled and installed, making the maintenance of the overall insulator more convenient and faster. Attached Figure Description

The fixing bolts and fixing holes 212 can fix the sealing disc 209 and the connecting rod 202. The annular spring 210 and the sealing disc 209 can seal the opening at the bottom of the conical groove 201 to prevent external dust from entering the interior of the conical groove 201.

The pressure plate 215 clamps and limits the rubber sheet 204, firmly securing the rubber sheet 204 and the rubber plug 203. The connecting cylinder 214 is fixedly connected to a connecting ball 216 at the top, and fixed clamps 217 are connected to both sides of the connecting ball 216.

A connecting groove 219 is opened at the top of the inner side of the fixed clamp 217. A bird deterrent whistle 220 is connected to the outside of the fixing clip 217. When the wind flows through the bird deterrent whistle 220, it will blow the bird deterrent whistle 220. The sound emitted by the bird deterrent whistle 220 can drive away birds and keep them away from the insulator. Two adjacent fixing clips 217 are connected by fixing bolts. A connecting piece 221 is connected to the bottom of the connecting rod 202. The connecting piece 221 is embedded in the adjacent connecting groove 219. The connecting piece 221 at the bottom of one insulator is embedded in the connecting groove 219 at the top of another insulator, realizing the end-to-end connection between each insulator. The connecting cylinder 214, pressure plate 215, connecting ball 216 and fixing clamp 217 are made of insulating alumina ceramic. Insulating alumina ceramic has good mechanical strength and high temperature resistance, so that the insulators connected end to end have good connection strength and insulation performance. The top and bottom of the three insulator bodies 1 are provided with convenient suspension components 3. The convenient suspension components 3 include a top suspension seat 301, a top suspension plate 302, a suspension rod 303, a suspension crossbar 304, a lifting plate 305, a movable opening 306, an I-shaped slider 307, a clamping ear 308, a clamping cylinder 309, a fixed ear 310, a clamping spring 311, a suspension clamp 312, a suspension groove 313, a bottom suspension seat 314, a bottom suspension plate 315, a fixed clamping plate 316, and a movable clamping plate 317. The top of the insulator body 1 is connected to a top suspension seat 301, the bottom of the top suspension seat 301 is connected to a top suspension piece 302, the top suspension piece 302 is embedded in the adjacent connecting groove 219, and the top of the top suspension seat 301 is connected to a suspension crossbar 304 via a suspension rod 303. A lifting plate 305 is provided at the top of the suspension crossbar 304. A movable opening 306 is provided in the middle of the lifting plate 305.

Fixed ears 310 are connected to both ends of the bottom of the lifting plate 305. The fixed ears 310 and the clamping ears 308 are connected by clamping springs 311. The bottom of the insulator body 1 is connected to two suspension clips 312. Each suspension clip 312 has a suspension groove 313 at both the top and bottom. The bottom connecting piece 221 is embedded in the top suspension groove 313. The two suspension clips 312 are connected and fixed by fixing bolts. A bottom suspension seat 314 is connected to the bottom of each suspension clip 312. A bottom suspension piece 315 is connected to the top of the bottom suspension seat 314 and is embedded in the bottom suspension groove 313. Tightening the fixing bolts can connect the two suspension clips. 312 is used for connection and separation. When the two suspension clamps 312 are connected, they can connect and fix the bottom insulator to the bottom suspension seat 314. When the two suspension clamps 312 are separated, they can separate the bottom insulator from the bottom suspension seat 314. The bottom of the bottom suspension seat 314 is also connected to a fixed clamp 316 through a suspension rod 303. The bottom of the fixed clamp 316 is connected to a movable clamp 317 through a fixing bolt. The fixed clamp 316 and the movable clamp 317 can clamp the conductor and, together with the hoisting of the insulator, realize the suspension and fixation of the conductor.

[0022] The working principle and usage process of this invention: A connecting ball 216 is connected to the top of the connecting cylinder 214. Two hemispherical grooves 218 form a spherical groove. The surface of the connecting ball 216 and the inner wall of the hemispherical groove 218 are both smooth surfaces. When the insulator swings, under the action of gravity, the connecting ball 216 rotates smoothly between the two hemispherical grooves 218. The series insulators can quickly return to a vertical state, ensuring the hoisting stability of the conductor. The suspension and fixing effect of the conductor is good, and the wind resistance is good. The insulator body 1 has a conical groove 201 inside. Multiple arc-shaped spring pieces 206 are welded to the outside of the connecting rod 202. A buffer spring 208 connects the arc-shaped spring pieces 206 to the connecting rod 202. The conical groove 201 provides bending space for the buffer spring 208 and the arc-shaped spring pieces 206. A rubber plug 203 and the arc-shaped spring pieces 206 isolate the connecting rod 202 from the insulator body 1. When the insulator body 1 swings in strong winds, the buffer spring 208 and the arc-shaped spring pieces 206 bend under force, and the rubber plug 203 deforms under force. The impact kinetic energy is converted into physical energy through the elastic deformation of the arc-shaped spring pieces 206, the buffer spring 208, and the rubber plug 203. The elastic potential energy is then slowly released to buffer the impact. During the swing of the insulator, the arc-shaped spring piece 206 and the rubber plug 203 separate the connecting rod 202 from the insulator body 1, so that the connecting rod 202 does not collide with the insulator body 1, avoiding friction between the insulator body 1 and the connecting rod 202, protecting the galvanized layer on the surface of the connecting rod 202, and preventing the reduction of the corrosion resistance of the connecting rod 202 due to damage to the galvanized layer. Compared with the existing technology, the service life of the connector is improved. Moreover, the arc-shaped spring piece 206 is evenly distributed on the outside of the connecting rod 202, which can fully protect the connecting rod 202 regardless of the wind direction, and the protection effect is good. When encountering strong winds, if the series-connected insulators are subjected to a sudden tensile force, the annular spring 210 and the rubber sheet 204 will undergo elastic deformation under the tensile force, converting the impact kinetic energy into elastic potential energy, and then slowly releasing the energy to buffer the impact. This protects the connectors between each insulator body 1 in the vertical direction, further improving the service life of the connectors. In addition, the annular spring 210 and the sealing disc 209 can seal the opening at the bottom of the conical groove 201, preventing external water and dust from entering the interior of the conical groove 201, avoiding water and dust corrosion of the connectors inside the conical groove 201, and extending the service life of the connectors. Two adjacent fixing clips 217 are connected by fixing bolts. The bottom end of the connecting rod 202 is connected to a connecting piece 221. The connecting piece 221 is embedded in the adjacent connecting groove 219. The connecting piece 221 at the bottom of one insulator is embedded in the connecting groove 219 at the top of another insulator, realizing the end-to-end connection between each insulator. This makes it convenient and quick to disassemble and install the connecting parts. When the ceramic of the insulator body 1 needs to be replaced, remove the individual insulator body 1, remove the connecting sleeve 214 and rubber plug 203, then remove the fixing bolt connected to the fixing hole 212, push the connecting rod 202 to move the fixing foot 207 out of the positioning ring groove 205, and then pull the sealing disc 209 down. Under the connection of the wire rope 211, the buffer spring 208 is compressed, and the arc-shaped spring piece 206 contracts. When the diameter of the contracted arc-shaped spring piece 206 is smaller than that of the conical spring... When the opening diameter at the bottom of the groove 201 is determined, the connecting rod 202 and the arc-shaped spring piece 206 are removed as a whole. After removal, the bottom of the conical groove 201 of the new insulator body 1 is aligned with the connecting rod 202. The connecting rod 202 is pushed, and the arc-shaped spring piece 206 is compressed by the conical groove 201. The arc-shaped spring piece 206 contracts until it is completely inserted into the conical groove 201. The ceramic of the insulator body 1 can be flexibly disassembled, which facilitates the reuse of the connecting parts and is more environmentally friendly. During insulator installation, the lifting plate 305 is connected and fixed to the crane tower. The I-shaped slider 307 is pulled to move inside the movable opening 306, so that the two ends of the suspension crossbar 304 are respectively inserted into the two clamping cylinders 309. The suspension crossbar 304 is clamped and fixed by the elastic force of the clamping spring 311. During subsequent insulator maintenance and replacement, the insulator can be disassembled and installed by pulling the I-shaped slider 307, which is convenient and quick. The top of the insulator body 1 is connected to a top suspension seat 301, which is connected to a fixing clamp 217 via a top suspension plate 302. The bottom suspension seat 314 is connected to a bottom suspension plate 315, which is embedded in the bottom suspension groove 313. Tightening the fixing bolt can connect and separate the two suspension clamps 312. When the two suspension clamps 312 are connected, they can connect and fix the bottom insulator to the bottom suspension seat 314. When the two suspension clamps 312 are separated, they can separate the bottom insulator from the bottom suspension seat 314. The bottom of the bottom suspension seat 314 is connected to a fixed clamp 316 via a suspension rod 303. The fixed clamp 316 and the movable clamp 317 can clamp the conductor. With the hoisting of the insulator, the conductor can be suspended and fixed. The number of insulators can be flexibly installed according to the needs, and the application range is wide.
