Description

Technical Field

[0001] This utility model relates to the technical field of protective covers for linear insulating terminals of power distribution networks, and in particular to a bird-proof insulating protective cover for insulating rod operation, a molding die for a conformal skeleton of composite materials, a molding die for prefabricated parts, and a vulcanization die. Background Technology

[0002] Birds' activities, nesting, and roosting on power line towers can easily lead to them touching live conductors, causing short circuits, tripping, and other accidents. This seriously affects the safe and stable operation of the power system and causes significant economic losses. Installing bird-proof insulating covers on the straight insulators of bare distribution conductors can prevent birds from contacting exposed conductors and joints, thus avoiding economic losses caused by power outages due to phase-to-phase short circuits, grounding, and other factors.

[0003] On 10kV high-voltage distribution lines, the bird-proof insulating protective covers currently in use are made of vulcanized silicone rubber. They have the natural softness of rubber products. When working without power interruption, they can only be installed using insulating gloves. This results in low efficiency of working at heights, high requirements for the skill level and physical fitness of the operators, and certain safety risks during the operation.

[0004] Using insulated rods allows workers to stay away from contact with live parts, improving safety. In addition, insulated rods can automate the operation, reduce labor intensity, and improve work efficiency and construction costs.

[0005] The bird-proof insulating protective cover used for the linear insulating terminal is a long tube structure. Due to the softness of the silicone rubber material, the current insulating protective cover cannot maintain its static shape during lifting and installation, and cannot meet the technical requirements of remote installation using the insulating rod operation method. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a bird-proof insulating protective cover for the insulating rod method, a molding die for a composite material conformal skeleton, a preform molding die, and a vulcanization die.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An insulating protective cover for bird protection using the insulating rod method, a molding die for a conformal composite skeleton, a precast molding die, and a vulcanizing die are disclosed. The protective cover includes an insulator cover and a lifting ring at its top. A conductor protective cover I and a conductor protective cover II are respectively provided on both sides of the insulator protective cover. The conductor protective cover I and conductor protective cover II are symmetrically arranged about the insulator protective cover. Both conductor protective cover I and conductor protective cover II have openings at their lower ends. The edges of the openings of conductor protective cover I and conductor protective cover II are respectively provided with retaining edges I and II, and both retaining edges I and retaining edges II are provided with detachable limiting structures.

[0009] Preferably, the detachable limiting structure includes a buckle, which is a flat spindle structure with one end being a tapered structure. Both the buckle edge I and buckle edge II are provided with several insertion holes corresponding to the buckle.

[0010] Preferably, the insulator protective cover is an inverted circular bowl-shaped structure.

[0011] Preferably, the intermediate layer of the insulator protective cover, conductor protective cover I and conductor protective cover II is embedded with a composite material conformal skeleton.

[0012] A molding die for a conformal skeleton of composite material includes a conformal skeleton forming female mold and a conformal skeleton forming male mold. The conformal skeleton forming female mold has a fiber layup recess on one side, and the conformal skeleton forming male mold has a male mold working surface on one side, which is a raised structure.

[0013] A bird-proof insulating protective cover for insulating rod operation, a molding mold for conformal composite material skeleton, a preform molding mold, and a preform molding mold for vulcanization, comprising a preform vulcanization female mold and a preform vulcanization male mold, wherein the preform vulcanization female mold and the preform vulcanization male mold are respectively provided with mutually interlocking female mold working surface and male mold working surface on opposite sides.

[0014] A mold for forming a bird-proof insulating protective cover, a composite conformal skeleton, a preform forming mold, and a vulcanizing mold for a vulcanizing mold, comprising a protective cover vulcanizing male mold, a protective cover vulcanizing upper female mold, and a protective cover vulcanizing lower female mold, wherein the protective cover vulcanizing male mold, the protective cover vulcanizing upper female mold, and the protective cover vulcanizing lower female mold are assembled by connecting parts.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the conductor protection cover and the edge clip are made of silicone rubber as a whole, which can be used as a protective sleeve for 10kV and 20kV insulators and has good versatility in distribution network lines; it can insulate and isolate the insulator and the nearby bare conductors, preventing birds from touching high-voltage live parts when they are active, causing short circuits, grounding and other faults in the line, ensuring the safe operation of power lines and avoiding economic losses caused by power outages.

[0016] The insulator and conductor protective covers are embedded with a high-rigidity composite material insulating skeleton, ensuring overall rigidity and maintaining their shape when lifted from any point. The lifting ring in the middle of the cover can be fitted into the hook of the gun-type insulating operating rod for installation using the insulating rod method. This allows workers to avoid contact with live parts, improving operational safety. Furthermore, the insulating rod can be used to automate the operation, reducing labor intensity, increasing work efficiency, and lowering construction costs, showing promising prospects for widespread adoption.
