Assembly type lightning arrester with adjustable length and stable installation

Abstract

The invention discloses an assembly type lightning arrester with adjustable length and stable installation, which comprises a base, a convex ring and a second propping rod, wherein a fixed cushion block is fixed to the lower end surface of the base, a mounting cushion block is in threaded connection with the lower end surface of the base, bolt holes are formed in the inner side of the mounting cushion block, a sleeve is fixed to the upper end surface of the base, an annular base is fixed to the outer side of the top of the sleeve, a connecting column is fixed to the top of the supporting column through a first stud, a threaded column is connected to the top of the connecting column in a threaded mode, a bearing seat is arranged at the top of the connecting block, and protruding blocks arefixed to the outer side of the lightning rod main body and the upper end surface of the bearing seat. According to the assembly type lightning arrester with adjustable length and stable installation,the connecting column and the supporting column can be fixed together by tightening the first stud, then the upper end and the lower end of a steel wire rope are tightened and fixed to the corresponding fixing rings, and the steel wire rope is in a tightened state at the moment, so that the connecting column is facilitated to be more stably placed.

Description

technical field [0001] The invention relates to the technical field of lightning protection devices, in particular to an assembled lightning protection device with adjustable length and stable installation. Background technique [0002] Lightning protection refers to avoiding the harm to the human body and buildings caused by lightning through certain methods and measures. Lightning rods, lightning wires, lightning nets, lightning protection belts, and lightning arresters are all commonly used lightning protection devices. A complete set of protection devices includes Lightning receptors, down conductors and grounding devices, the above-mentioned needles, wires, nets, and belts are just lightning receptors, and lightning arresters are a special lightning protection device. [0003] The placement height of the existing lightning protection device is not easy to adjust, and during the assembly process, the connection between the various parts is not tight enough. Not convenie...
