Description

Multi-gear adjustable one-code ventilation wind-proof fastening device Technical Field The utility model relates to the technical field of power clamps, in particular to a multi-gear adjustable one-code wind-proof fastening device. Background Insulators serve a dual important role in power transmission systems as key components in overhead lines. On the one hand, the high-voltage cable has excellent electrical insulation performance, can bear high voltage in the running process of the cable, prevents current from leaking to a tower or other grounding parts, and avoids electric shock accidents and power loss. The main function of the wire clamp is to firmly fix the high-voltage wire on the top of the insulator. The existing common power wire clamp directly forms the wire clamp in the forming process of the anchor ear, namely when two anchor ears clamp the top of the insulator, two opposite wire clamps on the anchor ear can clamp a high-voltage wire, and then the anchor ear is fixed by using bolts. However, in the using process of the power wire clamp with the structure, two halves of the anchor clamps are required to be installed at the same time, so that time and labor are wasted, and the labor efficiency is low. In order to solve the problem, a power wire clamp for insulator connection (chinese patent document with publication No. CN 211183307U) has been proposed, which includes a left clamp body and a right clamp body with their tops hinged together and disposed opposite to each other, the left clamp body and the right clamp body each have an integrally formed upper clamp head section, a lower clamp head section, and an end connection section connecting the lower part of the upper clamp head section and the side part of the lower clamp head section, the upper clamp head section has an outwardly protruding arc clamp arm, the arc clamp arm of the left clamp body and the arc clamp arm of the right clamp body are disposed opposite to each other so as to form a space for clamping a cable between the two arc clamp arms, the lower clamp head section has an outwardly protruding arc clamp arm, the arc clamp arm of the left clamp body and the arc clamp arm of the right clamp body are disposed opposite to each other so as to form a space for clamping the top of the insulator between the two arc clamp arms, and a bolt is inserted between the end connection section of the left clamp body and the end connection section of the right clamp body. The wire clamp can be used for rapidly fixing the cable and the insulator and has the advantages of being simple in structure, convenient to assemble and capable of improving labor efficiency. The insulator is clamped by the wire clamp through the left clamp body and the right clamp body, but a plurality of defects exist in a clamping cavity with a fixed size. Insulators in the power system are various in specification, insulators of different voltage grades and types are large in size and shape difference, clamping cavities of fixed sizes are difficult to adapt, application scenes of the insulators are limited, and model selection cost is increased. Under the complex installation and maintenance scene, the insulator replacement requirement cannot be flexibly met, and the repair progress is influenced. In addition, when the sizes are not matched, the insulators are prevented from shaking and wearing, the connecting pieces are loosened, or the insulators are subjected to additional stress to be damaged, so that the line safety is threatened. Meanwhile, enterprises need to purchase various types of wire clamps, so that the purchase and inventory management cost is increased, and resource waste is caused.
