Abstract

The invention belongs to the technical field of wind power blades, and particularly discloses a wind power blade lightning arrester mounting device and a mounting method. The wind power blade lightning arrester mounting device comprises an upper lightning arrester mounting assembly and a lower lightning arrester mounting assembly, the upper lightning arrester mounting assembly comprises a first positioning plug, a bonding layer, a C-shaped mounting pad, a guide shaft, a first tapper and a second tapper, one side of the C-shaped mounting pad is fixed to the inner wall of a lower shell body, the other side of the C-shaped mounting pad is fixed to a base of an upper lightning arrester, an internal threaded hole matched with the upper lightning arrester is formed in the base of the upper lightning arrester in advance, the first positioning plug comprises a screw rod and a positioning block, the upper end face of the positioning block is provided with a center hole and a plurality of annular grooves, the lower part of the positioning block is integrated with the screw rod; the lower lightning arrester mounting assembly comprises a second positioning plug, and the guide shaft can be inserted into the center holes of the first positioning plug and the second positioning plug and is used for guiding the second tapper. By means of the wind power blade lightning arrester mounting device, the problem that in the prior art, drilling cannot be accurately conducted perpendicular to the base can be solved.

Description

technical field [0001] The invention belongs to the technical field of wind power blades, and in particular relates to a wind power blade lightning receptor installation device and an installation method. Background technique [0002] Wind power blades work in high-altitude or open environments such as mountains, coasts, and seas. They are the objects closest to the clouds on the ground, and are extremely vulnerable to lightning strikes during thunderstorms. The blade lightning receptor can guide the lightning directionally and conduct the lightning current. The installation quality of the air receptor directly affects the operation safety of the blades and maintenance personnel. The most ideal installation is that the air-terminating device is in surface-to-face contact with the base, so as to obtain sufficient diversion cross-sectional area, and at the same time provide a stable connection and stable electrical conductivity. [0003] At present, the blade lightning prote...
