Abstract
A lightning-protection ring device of a wind generating set relates to the field of wind power generation equipment, mainly solves the problem that a main bearing pedestal is struck by lightning, and simultaneously avoids the phenomenon that a carton brush is worn down. The device comprises a spindle and the main bearing pedestal, and is characterized in that a copper ring coincident with a spindle axis is arranged between a spindle conical surface and the main bearing pedestal, the copper ring is fixed on four electric-conduction elastic brackets uniformly distributed on the end surface of the main bearing pedestal, one end of each elastic bracket is fixed on the main bearing pedestal through a bolt, the other end of each elastic bracket is connected with an electric-conduction pin, and the pin is electrically contacted with the spindle conical surface. The copper ring connects the four electric-conduction elastic brackets into a whole, so that lightening transmission can still be ensured although one of the four electric-conduction elastic brackets has a bad contact; and the lightening on a blade can be transmitted to the ground through the spindle, a lightning-protection ring, the main bearing pedestal, an engine room and a tower cylinder, so that the safety of the wind power generation equipment, in particular the main bearing pedestal, can be ensured, and the maintenance cost is reduced.
Description
Technical field
The utility model relates to the wind power plant field, is specifically related to the lightning-arrest loop device of a kind of wind power generating set.
Background technique
Because wind power generating set is operated in spacious field throughout the year, physical environment is abominable, and the wind power generating set height is very high, be struck by lightning extremely easily, so it is crucial that wind power generating set is handled through the row lightning protection, particularly the wind driven generation set main shaft bearing needs the most important thing of taking shelter from the thunder especially.And the lightning-arrest mode of the carbon brush of taking now, because of main shaft be often between running, the carbon brush wearing and tearing are more serious, and the carbon dust that weares and teares can impact the running environment of wind-powered electricity generation unit in the cabin.
The model utility content
The purpose of this utility model is to overcome the problem that above-mentioned prior art exists, and a kind of wind power generating set loop device of take shelter from the thunder is provided, and this device can effectively be protected main bearing seat, prevents to be struck by lightning, and has avoided the generation of wear phenomenon.
The technical scheme in the invention for solving the technical problem is, this wind power generating set loop device of taking shelter from the thunder, relate to main shaft and main bearing seat, it is characterized in that, be provided with a copper ring consistent with main-shaft axis between the main shaft conical surface and main bearing seat, described copper ring is fixed on four electrically conductive elastic supports that are distributed on the main bearing seat end face, and described elastic support one end is by being bolted on the main bearing seat, the other end connects the conduction pin, and the described pin and the main shaft conical surface electrically contact.
Described pin is positioned at elastic support end one pin hole, on pin and the above and below that is positioned at the elastic support end be equipped with the adjustment nut.
Further, with the elastic support of copper ring joint on be provided with attachment hole, the bar head of a screw rod is provided with the through hole that passes through for copper ring, described bar head places in the fillister skeleton that is fixed on the elastic support, screw rod passes attachment hole and is locked by tightening nut.
The beneficial effects of the utility model are, because copper ring is connected as a single entity four electrically conductive elastic supports, even one in four pins bad connection occurs, still can guarantee the transmission of thunder and lightning, thunder and lightning on the blade is passed earthward by main shaft, lightning-arrest ring, main bearing seat, cabin, tower tube, guarantee the particularly Security of main bearing seat of wind power plant, reduced maintenance cost.
