Description

Technical Field

[0001] The invention relates to the technical field of overhead line hardware deicing, in particular to an overhead line hardware with a deicing device. Background Art

[0002] Overhead line fittings are metal accessories that connect and combine various devices in overhead power lines, and serve to transmit mechanical loads, electrical loads, and provide some protection. They include suspension fittings, tension fittings, connecting fittings, splicing fittings, and protective fittings. Suspension fittings are mainly used to suspend conductors or optical cables on insulators or towers, and are mostly used on linear towers. Common types include U-shaped screw-type suspension clamps (CGU), suspension clamps with U-shaped hanging plates (CGU-A), and aluminum alloy suspension clamps (CGH). Existing suspension fittings do not have the ability to de-ice during use, and thus, during icing, they can easily cause phase-to-phase short circuits and line tripping. If suspension fittings have a de-icing effect, they can reduce conductor icing, reduce the conductor bounce and swing amplitude caused by icing, maintain phase-to-phase distance, and prevent short-circuit accidents.

[0003] According to the description of a single-link suspension hardware string structure published on the patent website (authorization announcement number: CN214124766U), the single-link suspension hardware string structure includes "ground wire suspension clamp, connecting hanging plate, adjustment parts" and so on to achieve suspension work.

[0004] In view of the above description, the applicant believes that the following problems exist: The single-link suspension hardware string structure uses ground wire suspension clamps, connecting hanging plates, adjusting parts, etc. to achieve suspension work. This structure does not have the ability to de-ice during use. During the icing process, it is easy to cause phase-to-phase short circuits and line tripping. Icing will greatly increase the weight of the conductors, generate huge pressure and tension on the pole tower, and affect the safety and stability of cable use. Therefore, this structure needs to be improved. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The overhead line hardware with de-icing device has a de-icing mechanism. When the hanging hardware is fixed to the outer periphery of the cable and is in a stable state during use, the ice-breaking roller is at the bottom of the cable and contacts the cable surface. At the same time, the ice-breaking balls are at the front and back sides of the cable. The mounting frame can be plugged into the bottom of the fixing seat and connected to the hanging hardware. When it is necessary to de-ice the cable surface near the hanging hardware, the servo motor drives the first gear fixed to the outer periphery of the first rotating rod to rotate, so that the first gear drives the ice-breaking roller to rotate. When the ice-breaking roller rotates, the ice-breaking hammer can be driven to rotate. Under the action of the ice-breaking hammer, the ice-breaking roller rotates. The ice on the surface of the cable is broken down to remove ice and vibrate. When the ice-breaking roller rotates, the second gear is driven to rotate through the second rotating rod, so that the second gear drives the third gear that is meshed with each other to rotate, and the third gear drives the rotating disk and the ice-breaking ball to rotate. Under the action of the ice-breaking ball, the front and rear sides of the cable are de-iced, and the cable is vibrated to expand the scope of de-icing. The ice layer is broken by the rotating ice-breaking hammer of the ice-breaking roller, and the reciprocating impact of the ice-breaking balls symmetrically arranged on both sides under the action of centrifugal force forms a multi-angle and multi-frequency three-dimensional de-icing effect, thereby improving the efficiency and thoroughness of de-icing.

[0017] 2. The overhead line hardware with de-icing device has an ice-breaking ball and a rotating groove and a movable groove integrated inside the protective box, which provides a stable motion track for the ice-breaking roller and gear set, reduces mechanical wear, and the symmetrically distributed load-bearing arm and rotating disk structure effectively disperse the impact force during de-icing operation, enhancing the overall rigidity and fatigue resistance of the device. The ice-breaking ball adopts a first spring elastic connection, which can adapt to the curvature of the conductor surface during rotation to avoid damage to the conductor caused by rigid contact. In addition, the ice-breaking roller, ice-breaking hammer, rotating disk and ice-breaking ball are all made of insulating materials to improve safety and insulation.

[0018] At the same time, the limiting plate is released, and the second spring is reset, which allows the baffle to move to the front side of the rotating frame, limiting the rotating frame to avoid rotation and ensuring the stability of the plug when working.

[0019] 4. The overhead line hardware with a de-icing device, through the provided fixing mechanism, when the suspension hardware is fixed to the periphery of the cable during use, the mounting bracket is plugged into the bottom of the fixing seat, and the mounting bracket is limited by the limit pin to ensure the stability of the mounting bracket. At the same time, the support frame is rotated in the second concave frame so that the support seat is at the bottom of the mounting bracket. The adjusting shaft is rotated to drive the support seat to move up and down, so that the support seat is slidably connected to the bottom of the mounting bracket, and the bottom of the support seat is in contact with the bottom of the mounting bracket, which can further support the mounting bracket, ensure the stability of the mounting bracket and the protective box, and ensure the stability between the mounting bracket, the fixing seat and the suspension hardware, ensure the safety and stability of the de-icing work, and facilitate installation and disassembly, and facilitate maintenance work.

[0032] Furthermore, the limit pin 22 passes through the interior of the mounting bracket 31, and fixing grooves are respectively provided inside the mounting bracket 31 and the fixing seat 21, and the two fixing grooves correspond to each other. The limit pin 22 is threadedly connected to the fixing groove, and the bottom inner bottom of the support seat 26 contacts the bottom of the mounting bracket 31, so that under the action of the limit pin 22, when the mounting bracket 31 is inserted into the bottom of the fixing seat 21, it is fixed.

[0034] When the cam 24 is in the upright position, the support frame 31 is fixed to the outer periphery of the cable, and the cam 24 is fixed to the outer periphery of the cable, and the cam 24 is fixed to the outer periphery of the cable, and the cam 24 is fixed to the outer periphery of the cable, and the cam 24 is fixed to the outer periphery of the cable, and the cam 24 is fixed to the outer periphery of the cable, and the cam 24 is fixed to the outer periphery of the cable, and the cam 24 is fixed to the outer periphery of the cable, and the cam 24 is fixed to the outer periphery of the cable, and the cam 24 is fixed to the outer periphery of the cable, and the cam 24 is fixed to the outer periphery of the cable, and the cam 24 is fixed to the outer periphery of the cable, and the cam 24 is fixed to the outer periphery of the cable, and the cam 24 is fixed to the outer periphery of the cable, and the cam 24 is fixed to the outer periphery of the cable, When the suspension fitting 1 is fixed to the outer periphery of the cable during use, and the fixing between the mounting bracket 31 and the fixing seat 21 is completed, first pull the limit plate 49 to the left, so that the limit plate 49 drives the connecting rod 47 and the baffle 46 to move, and deforms the second spring 48, so that the rotating frame 44 rotates vertically in the first concave frame 43, and slides the connecting arm 42 to the inside of the mounting seat 41.

Under the action of the ice-breaking ball 396, the front and rear sides of the cable are de-iced and the cable is vibrated to expand the range of de-icing. The rotating ice-breaking hammer 393 of the ice-breaking roller 38 breaks the ice layer, and the reciprocating impact of the ice-breaking balls 396 symmetrically arranged on both sides under the action of centrifugal force forms a multi-angle and multi-frequency three-dimensional de-icing effect, thereby improving the efficiency and thoroughness of de-icing. By setting up the ice-breaking ball 396, the rotating groove and the movable groove are integrated inside the protective box 32, providing a stable motion track for the ice-breaking roller 38 and the gear set, reducing mechanical wear, and the symmetrically distributed load-bearing arm 394 and the rotating disk 395 structure effectively disperse the impact force during the de-icing operation, enhancing the overall rigidity and anti-fatigue performance of the device. The ice-breaking ball 396 is elastically connected with the first spring 397, which can adapt to the curvature of the wire surface during rotation to avoid damage to the wire caused by rigid contact.
