The integrated insulation mechanical solution is provided for solving the difficult problem that the fuse porcelain insulator and the mounting plate are easy to separate and need to be subjected to power failure maintenance in the prior art. The device is vertically distributed through the space of the semicircular hook-shaped fixer and the clamping groove-type fixer, and combines the obtuse angle bending connecting rod to form a bidirectional clamping structure, wherein the inner wall of the semicircular hook body is provided with a trapezoid anti-slip convex strip and a grid reinforcing rib, the surface of a porcelain bottle is coated in a self-adaptive manner in an elastic deformation range, and the self-locking clamping connection of the channel steel mounting plate is realized through the design of the anti-falling chamfer and the gradual change thickness of the U-shaped groove side plate. By utilizing the integral molding characteristic of the insulating material, the upper clamping and the lower clamping can be synchronously completed through single pushing and pulling of the insulating rod during operation, so that the porcelain insulator and the mounting plate form rigid connection, and safety reinforcement is realized under the electrified state through a hook-groove bidirectional mechanical transmission path and an elastic deformation compensation mechanism.

Description

Fuse porcelain bottle fastening hook capable of being installed in electrified mode Technical Field The utility model relates to the technical field of high-voltage operation equipment, in particular to a fuse porcelain insulator fastening hook capable of being installed in an electrified mode. Background The overhead distribution line is used as a core carrier for electric energy transmission of urban and rural power grids in China, and the safe operation of the overhead distribution line directly relates to the power supply reliability. The drop-out fuse is used as key equipment for branch line short-circuit protection and long-term faces the falling risk caused by ageing and separation of a porcelain insulator-mounting plate casting body. The traditional maintenance mode needs to manually climb the tower to be replaced after the power failure of the whole circuit line, and has the inherent defects of large power failure range, long rush repair time consumption and the like. Aiming at the difficult problem of live replacement, the Chinese patent No. CN210607690U provides an electric driving type grounding wire clamp which is meshed by a built-in electric cylinder to replace an insulating operating rod. The technology has obvious limitations that 1) a storage battery power supply system is relied on, the risk of circuit failure exists in a low-temperature and humid environment, 2) the whole weight of an electric cylinder-push rod transmission mechanism is increased, hidden danger of falling off hands exists in high-altitude operation, and 3) accurate angle fine adjustment required by fuse installation cannot be realized in an insulating rope remote control mode.
