Description

Technical Field

[0001] This utility model relates to the field of insulator technology, and in particular to power distribution line insulators that can be quickly repaired. Background Technology

[0002] During the construction of power distribution lines, line insulator overvoltage protectors are generally used to protect the lines from lightning strikes. In use, the insulators are installed below or on both sides of the crossarm of the pole, near the connection point between the jumper and the conductor, to attract lightning and protect the power distribution lines.

[0003] However, in actual use, the overvoltage and high current generated by lightning strikes can easily cause flashover and breakdown on the surface of the insulator, or even damage the insulator. Once the insulator fails, it will not only affect the normal transmission of power, but may also cause a power outage.

[0004] Existing technology, such as the Chinese utility model patent with application number CN202020756531.4 entitled "A Combined Insulator," has the key technical point that the assembled insulator is composed of multiple separate insulators, including an upper insulator comprising sheds, a U-shaped steel cap, and an upper insulator covering; a middle insulator comprising sheds, an embedded part, and a covering; and a lower insulator comprising sheds, a lower insulator embedded part, and steel feet. By dividing the insulator into different separate structures, when one of the separate insulators fails, only the damaged part needs to be replaced.

[0005] However, after two adjacent split insulators are axially fitted together, they are radially positioned by locking springs. As a whole, the insulator is divided into multiple segments. If any locking spring fails, the split insulators will shift and become a flexible connection. The entire insulator structure is unstable and cannot withstand extreme weather such as strong winds.

[0006] Therefore, there is a need for an insulator that can quickly replace damaged insulator parts while maintaining the stability of the entire insulator structure. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a rapidly repairable power distribution line insulator, solving the technical problem of balancing rapid replacement and structural stability in split insulators during practical use. A power distribution line insulator that can be quickly repaired includes a skirt, and also includes a handle, a fixing rod, and a wire clamp connected in sequence, wherein the wire clamp is used to clamp the line; The outer diameter of the handle is smaller than the outer diameter of the fixed rod. The handle and the fixed rod are fixedly connected. A threaded cylinder is threaded onto the outer surface of the handle. The threaded cylinder is a round cover with its opening facing the fixed rod. The bottom of the round cover has a threaded hole that matches the outer surface of the handle. The threaded cylinder can cover the outside of the fixed rod. The fixing rod is fitted with multiple umbrella skirts and stops; the stops are fixed to the fixing rod. The inner wall of the umbrella skirt is fixed with a sleeve, and the plurality of umbrella skirts are positioned between the threaded cylinder and the stop block; The sleeve is provided with a slider, and the fixed rod has a groove between the end near the handle and the stop block, and the slider can extend into the groove; The radius of the handle is smaller than the distance between the sliding groove and the axis of the fixed rod.

[0008] Furthermore, the sleeve is provided with two opposing sliders, and the corresponding fixed rod is provided with two grooves.

[0009] Furthermore, it also includes a nut block that is threaded onto the outside of the handle, the nut block abutting against the bottom of the threaded cylinder cap.

[0010] Furthermore, the wire clamp hardware includes: The mounting block is U-shaped and is fixedly connected to the fixing rod. A movable screw is threaded to one side wall of the mounting block, with both ends of the movable screw passing through the side wall; The locking block is inserted into the other side wall of the mounting block, and its inner end, which extends into the interior of the mounting block, is inserted into the interior of the movable screw. The other side wall of the mounting block has a stepped through hole that is thicker in the middle and thinner at both ends. The outer end of the card block is thickened so that the thickened part slides into the middle part of the stepped through hole. A spring is built into the middle part of the stepped through hole and elastically supports the outer end of the card block; The pull rod is fixedly connected to the outer end of the locking block, and is fitted inside the spring and the stepped through hole and extends out of the other side wall; A protrusion is fixedly sleeved on one end of the movable screw that extends into the mounting block, and the protrusion can compress the wire.

[0011] Furthermore, a fixing pad is fixedly connected to the inner wall of the mounting block.

[0012] In the above technical solution, the rapidly repairable power distribution line insulator of this utility model has the following beneficial effects: This rapidly repairable power distribution line insulator utilizes a combination of a fixed cylinder, a fixed rod, and a slider. When the sheds are damaged, the threaded cylinder is removed, along with the damaged shed and its inner wall fixed cylinder, and the intact one is installed and secured with the threaded cylinder. This allows for rapid repair and replacement, resolving issues such as flashover, breakdown, and even insulator damage. Insulator failures not only disrupt normal power transmission but can also lead to power outages. Furthermore, adjacent sheds are fitted onto the fixed rod and clamped between the threaded cylinder and the stop block, fixing their axial direction. The radial direction of each shed is limited by the slider and groove. Therefore, unlike existing technologies, there is no direct connection between adjacent sheds; instead, each shed is individually connected to the fixed rod. There is no flexible connection or positional movement between sheds, ensuring secure and reliable shed positioning. Attached Figure Description

[0017] like Figure 1-3The diagram shows a power distribution line insulator that can be quickly repaired, including a skirt 1, a handle 2, a fixing rod 3, and a wire clamp connected in sequence, the wire clamp being used to hold the line.

[0018] The outer diameter of the handle 2 is smaller than the outer diameter of the fixed rod 3. The handle 2 and the fixed rod 3 are fixedly connected. A threaded cylinder 21 is threadedly fitted onto the outer surface of the handle 2. The threaded cylinder 21 is a round cover with its opening facing the fixed rod 3. The bottom of the round cover has a threaded hole that matches the outer surface of the handle 2. The threaded cylinder 21 can be placed on the outside of the fixed rod 3. The bottom of the threaded cylinder 21 is a round plate with a certain thickness and is threadedly connected to the outer surface of the handle 2.

[0019] The fixing rod 3 is a rod on which multiple umbrella skirts 1 and stops 22 are fitted; the stops 22 are fixed to the fixing rod 3.

[0020] A sleeve 11 is fixed to the inner wall of the umbrella skirt 1. A slider 12 is provided on the sleeve 11. A groove is formed between the end face of the fixing rod 3 near the handle 2 and the stop block 22, and the slider 12 can extend into the groove. The outer diameter of the threaded cylinder 21 can be equal to the outer diameter of the sleeve 11, and one end face of the threaded cylinder 21 abuts against the end face of the sleeve 11. Multiple sleeves 11 are positioned between the threaded cylinder 21 and the stop block 22, so that the umbrella skirt 1 is positioned between the threaded cylinder 21 and the stop block 22.

[0021] The radius of the handle 2 is smaller than the distance from the bottom of the groove to the axis of the fixed rod 3, and the outer diameter of the handle 2 is smaller than the outer diameter of the fixed rod 3. These two requirements facilitate the installation of the umbrella skirt 1, sleeve 11, and slider 12. The slider 12 can slide into the groove from the end of the fixed rod 3 that connects to the handle 2. The slider 12 protrudes from the inner surface of the sleeve 11, and its length is along the axial direction of the fixed rod. The slider 12 is elongated. The cross-sectional shape of the slider 12 matches that of the groove, preferably a semi-circular or rectangular groove for easy machining.

[0022] Preferably, two opposing sliders 12 are provided and fixed on the sleeve 11, and two sliding grooves are formed on the corresponding fixing rod 3. That is, the two sliding grooves are arranged in the radial direction of the fixing rod 12. This symmetrical design facilitates fixing the position of the sleeve 11.

[0023] Preferably, to more securely lock the threaded cylinder 21 in place, a nut block is also included, which is threadedly connected to the outside of the handle 2 and abuts against the bottom of the cap of the threaded cylinder 21. The nut block is located outside the threaded cylinder 21 and serves to lock the nut in place.

[0024] The wire clamp fitting is prior art. See also Chinese utility model patent application number CN201420179967.6 "Composite Insulator" and Chinese utility model patent application number CN201120423819.0 "Insulator Fixing Suspension Wire Clamp"; or the preferred embodiments below.

[0025] Preferably, the wire clamp hardware includes: The mounting block 4 is U-shaped and is fixedly connected to the fixing rod 3.

[0026] The movable screw 31 is threaded to one side wall of the mounting block 4, with both ends of the movable screw 31 passing through the side wall. A nut is provided at the outer end of the movable screw 31 outside the mounting block 4 to facilitate rotation of the movable screw, and a through slot is provided at the inner end of the movable screw 31 inside the mounting block 4.

[0027] The locking block 32 is inserted into the other side wall of the mounting block 4, and its inner end, which extends into the interior of the mounting block 4, is inserted into the interior of the movable screw 31; the locking block 32 is rod-shaped, and its inner end can extend into the through slot hole.

[0028] The other side wall of the mounting block 4 has a stepped through hole that is thicker in the middle and thinner at both ends. The outer end of the locking block 32 is thickened so that the thickened part slides into the middle part of the stepped through hole. The final shape of the locking block 32 is T-shaped, with the thickened part located in the thickened hole in the middle of the stepped through hole. The inner end of the locking block 32 extends out from the other side wall of the mounting block 4. The stepped through hole can prevent the locking block 32 from detaching from the other side wall.

[0029] Spring 33, built into the middle part of the stepped through hole, in the larger hole, is used to elastically support the outer end of the locking block 32. Spring 33 abuts against the end face of the outer end of the locking block 32 and the stepped through hole.

[0030] Pull rod 34 is fixedly connected to the outer end of the locking block 32, and is fitted inside the spring 33 and the stepped through hole and extends out of the other side wall.

[0031] A protrusion 35 is fixedly connected to one end of the movable screw 31 that extends into the mounting block 11. The protrusion 35 can compress the wire and thicken the outer surface of the inner end of the movable screw. A blind hole is provided on the inner wall of one side wall to accommodate the protrusion 35.

[0032] The movable screw 31, protrusion 35, locking block 32, and spring 33 are arranged in sequence.

[0033] Before use, the movable screw 31 retracts, causing the protrusion 35 to be housed within the blind hole, or at least half of its volume to be located within the blind hole, thus moving the protrusion 35 away from the center of the circuit and the inner end of the locking block 32 away from the movable screw. Pulling the pull rod 34 compresses the spring, allowing the circuit to pass between the protrusion 35 and the locking block 32 into the mounting block 4. Releasing the pull rod 34 allows the locking block 32 to approach the movable screw 31. Rotating the movable screw causes the inner part of the movable screw 31 to fit over the outer part of the locking block 32. Simultaneously, the protrusion 35 presses against the circuit, securing the mounting block 11.

[0034] The inner wall of the mounting block 4 is fixedly connected with a fixing pad 41. The fixing pad 41 can be made of rubber to protect the wires. When the mounting block 11 is fitted onto the outer wall of the line, it can fit tightly against the outer wall of the line and prevent excessive pressure from damaging the line.

[0035] The umbrella skirt 1 is made of carbon ceramic material, which has good insulation properties, making it easy to insulate. With the help of the mounting block, the insulation device can be installed on the line. When the umbrella skirt 1 is damaged, it can be quickly replaced and repaired by disassembling the threaded cylinder.

[0036] The sleeve 11 and the umbrella skirt 1 are preferably made of the same material, such as carbon ceramic, or other materials available in the prior art, as long as they meet the technical solution described in this embodiment. The two are integrally formed and fired. When installing the umbrella skirt 1, the sleeve 11 is limited by a stop block, and a threaded cylinder is used to press against the other side of the sleeve 11, so that the umbrella skirt 1 is positioned on the outer wall of the fixing rod. This makes it convenient to inspect the umbrella skirt 1.

[0037] After the damaged umbrella skirt 1 is replaced, rotate the threaded cylinder to press it against the outer wall of the fixed cylinder. This fixes the repaired umbrella skirt 1 to the outer wall of the fixed rod, making it convenient for workers to repair.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
