Description

Technical Field

[0001] This utility model relates to the technical field of high voltage and insulation of railway contact networks, and in particular to a post-installed anti-flashover umbrella for rod-shaped porcelain insulators. Background Technology

[0002] Enlarging some of the sheds of insulators to prevent bird damage and contamination, thereby preventing flashover, has become a trend in insulator design in recent years, and its research significance has been recognized by the China State Railway Group.

[0003] However, current designs for enlarged insulator umbrellas are limited to composite insulators, while porcelain insulators are difficult to enlarge due to limitations in manufacturing processes and material properties. my country has a vast territory, diverse terrain, and dense railway lines. In farmland and mountainous areas, the intrusion of flora and fauna into the railway contact network frequently causes flashover accidents. Furthermore, a large number of porcelain insulators have already been installed. Replacing all existing porcelain insulators in areas requiring enlarged umbrellas with enlarged composite insulators would not meet the requirements of economic efficiency.

[0004] In addition, for composite insulators, due to the commonly used injection molding or compression molding process, the position of the large umbrella is fixed according to the mold. Currently, rod-shaped composite insulators generally only have one large umbrella on the grounding side. However, according to the actual operation and maintenance experience of railway contact networks, in mountainous areas, creeping plants and reptiles climb up the towers. Because the surfaces of the towers and the grounding side fittings of the insulators are rough, plants and animals can easily cross the first large umbrella on the grounding side, causing the large umbrella to fail and thus causing a flashover accident. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a post-installed anti-flashover umbrella for rod-shaped porcelain insulators that meets engineering economic requirements and has flexible installation positions.

[0006] This invention relates to a retrofitted anti-flashover umbrella for rod-shaped porcelain insulators, comprising a clamping plate and an umbrella-shaped plate. The umbrella-shaped plate is disposed on the outer side of the clamping plate. A connecting assembly is also included. The clamping plate and the umbrella-shaped plate are connected to the insulator via the connecting assembly and a waterproof sealant. In use, the clamping plate and the umbrella-shaped plate are clamped onto the insulator without an umbrella using the connecting assembly, and adhesive is applied to the contact interface to complete the installation of the umbrella-shaped plate. This invention enables the retrofitting of insulators without umbrellas in operation, obtaining insulators with umbrellas, which is more economical than complete replacement. This invention also features flexible installation location; the umbrella-shaped plate can be positioned in the center of the insulator's skirt. Several smooth porcelain skirts between the grounding side hardware and the umbrella-shaped plate increase the difficulty for plants and animals to cross the umbrella, thereby preventing flashover. Preferably, the connecting assembly includes a locking hole, a notch, a reinforcing plate, and bolt holes. The locking plate has a locking hole, and the umbrella-shaped plate has a notch that communicates with the locking hole. Each set of reinforcing plates is provided on one of the two sets of end faces of the notch. Each set of reinforcing plates has multiple sets of bolt holes, and the bolt holes on the two sets of reinforcing plates overlap each other. During installation, a waterproof sealant suitable for the interface material is applied to the interface between the locking plate and the insulator, allowing the insulator to enter the locking hole between the notch and the insulator. Then, the multiple sets of bolt holes on the two sets of reinforcing plates overlap each other. After that, the nylon bolt is threaded through the two sets of overlapping bolt holes and connected to the nylon nut, or it is fixed with a reliable, secure, and convenient nylon clip, thereby completing the fixed installation of the locking plate and the umbrella-shaped plate. The installation is convenient and the position selection is flexible.

[0007] Preferably, it also includes reinforcing ribs, and multiple sets of reinforcing ribs are provided between the umbrella-shaped plate and the clamping plate, with all sets of reinforcing ribs located below the umbrella-shaped plate; the multiple sets of reinforcing ribs support the umbrella-shaped plate to prevent deformation of the umbrella-shaped plate, and at the same time, the reinforcing ribs strengthen the connection between the clamping plate and the umbrella-shaped plate.

[0008] Preferably, the card plate and the umbrella-shaped plate are set at a certain angle; the card plate and the umbrella-shaped plate are set at a certain angle, and depending on the angle, they can be used in combination with insulators installed on flat arms, inclined arms or other positions to improve flexibility.

[0009] Preferably, the card plate, umbrella-shaped plate, reinforcing plate, and reinforcing rib are made of high-temperature vulcanized silicone rubber.

[0010] Preferably, the card plate, umbrella-shaped plate, card hole, notch, reinforcing plate, bolt hole and reinforcing rib are integrally formed.

[0011] Compared with existing technologies, the advantages of this invention are as follows: During use, the clamping plate and umbrella-shaped plate are engaged with the insulator without a large umbrella using the connecting components, and adhesive is applied to the contact interface to complete the installation of the umbrella-shaped plate. This invention enables the retrofitting of insulators without a large umbrella that are already in operation, resulting in insulators with a large umbrella, which is more economical than complete replacement. This invention also features flexible installation location; the umbrella-shaped plate can be positioned in the center of the insulator's skirt. Several smooth porcelain skirts between the grounding side hardware and the umbrella-shaped plate increase the difficulty for plants and animals to cross the large umbrella, thus preventing flashover.
