Abstract
The utility model discloses a lightning protection device of a blade hub of a wind driven generator, comprising a connecting plate, a nylon sheet and a copper bar, wherein one end of the connecting plate is provided with two or more copper belt fastening bolts, and the other end thereof is fixed at the middle part of the nylon sheet; and the two ends of the nylon sheet is provided with the copper belt fastening bolts which are provided with copper rods. The middle part of the connecting plate is of an arc-shaped or convex structure. The device connects the blade and the hub together by a bracket. The bracket is arranged on the position of the blade connecting flange with opposite installing angles of 0 degree and 180 degrees. Bolts passing through two M12 are fixed on a flange inner ring. The lightning protection device has simple structure and convenient installation and can guide current into the hub faster.
Description
Technical field
The utility model relates to a kind of blade of wind-driven generator wheel hub lighting protection device, can be installed on the wind power generating set, realizes the lightning protection between blade and wheel hub.
Background technique
Wind energy is a kind of inexhaustible clean energy resource, and China wind energy power station is through for successive years high speed development, and total installation of generating capacity has come Asia first.
As everyone knows, wind power generating set will be installed in abundant coastal, Plain of wind energy resources or massif area, and the high point of fan blade can reach more than hundred meters, and the high blower fan that towers is very easily hit by thunder and lightning.The huge energy that thunder and lightning discharges can cause wind power generation unit blade, damage of bearings, and generator insulating is breakdown, and controlling parts is burnt etc.In case thunderbolt occurs, give the wind-powered electricity generation unit maintenance, to change impaired parts expense huge.
When thunderbolt takes place, conducting lightning currents conducts to ground by the wind-driven generator assembly, because wind-driven generator is positioned at the strong wind district, usually addressing is on the open hills or ridge of spaciousness, its height far above around terrain and its features, it is higher usually to add wind-driven generator infield soil resistivity, conductive performance to lightning current is relatively poor relatively, be subjected to the attack of direct lightning strike, sideflash and induction thunder especially easily, therefore, take lightning protection measures to be very important the wind-driven generator assembly.
The model utility content
This lighting protection device can solve the lightning protection problem between present blade and the wheel hub.At above technical problem, of the present utility model a kind of blade wheel hub lighting protection device proposed, comprise connecting plate 1, nylon sheet 2 and copper rod 3; Described connecting plate 1 one ends are provided with two or more copper strips clamping bolts; Described connecting plate 1 the other end is fixed on nylon sheet 2 intermediate portions; Described nylon sheet 2 two ends are provided with the copper strips clamping bolt; Described copper strips clamping bolt is provided with copper rod 3.Described connecting plate 1 intermediate portion camber or protruding structure.
This device couples together blade and wheel hub by a support.This support is installed in 0 ° of position that established angle is relative 180 ° on the blade adpting flange.By being bolted on the flange inner ring of two M12.In order to prevent that pitch variable bearings from being punctured by thunder and lightning, this support strides across bearing, connects a nylon sheet 2 by bolt, and two lightning protection copper rod 3 is installed at nylon sheet 2 two, and copper has the performance of favorable conductive, and nylon sheet 2 has better elastic.The lightning protection copper strips is connected on the connecting plate 1 by two bolts on the flange on the blade, is connected to copper rod 3 positions of nylon sheet 2 again with a copper strips, and the centre is simple fixing a little, and copper strips is fixed on the connecting plate 1.So just the electric current on the blade is led on the wheel hub, thereby realized lightning protection between blade and the wheel hub.Electric current is led in the shortest time down for convenience, places two copper strips on this support.This lighting protection device is simple in structure, and is easy for installation, can faster electric current be imported wheel hub, and hope can obtain promoting.
Description of drawings:
Fig. 1 is a blade wheel hub lighting protection device structural representation of the present utility model;
Fig. 2 is the utility model blade wheel hub lighting protection device plan view.
Wherein: 1 is connecting plate; 2 is nylon sheet; 3 is copper rod.
Embodiment:
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 1,2, of the present utility model a kind of blade wheel hub lighting protection device proposed, comprise connecting plate 1, nylon sheet 2 and copper rod 3; Described connecting plate 1 one ends are provided with two or more copper strips clamping bolts; Described connecting plate 1 the other end is fixed on nylon sheet 2 intermediate portions; Described nylon sheet 2 two ends are provided with the copper strips clamping bolt; Described copper strips clamping bolt is provided with copper rod 3.Described connecting plate 1 intermediate portion camber or protruding structure.
This device couples together blade and wheel hub by a support.This support is installed in 0 ° of position that established angle is relative 180 ° on the blade adpting flange.By being bolted on the flange inner ring of two M12.In order to prevent that pitch variable bearings from being punctured by thunder and lightning, this support strides across bearing, connects a nylon sheet 2 by bolt, and two lightning protection copper rod 3 is installed at nylon sheet 2 two, and copper has the performance of favorable conductive, and nylon sheet 2 has better elastic.The lightning protection copper strips is connected on the connecting plate 1 by two bolts on the flange on the blade, is connected to copper rod 3 positions of nylon sheet 2 again with a copper strips, and the centre is simple fixing a little, and copper strips is fixed on the connecting plate 1.So just the electric current on the blade is led on the wheel hub, thereby realized lightning protection between blade and the wheel hub.Electric current is led in the shortest time down for convenience, places two copper strips on this support.This lighting protection device is simple in structure, and is easy for installation, can faster electric current be imported wheel hub, and hope can obtain promoting.
Above content is to further describing that the utility model is done in conjunction with concrete preferred implementation; can not assert that embodiment of the present utility model only limits to this; for the utility model person of an ordinary skill in the technical field; under the prerequisite that does not break away from the utility model design; can also make some simple deduction or replace, all should be considered as belonging to the utility model and determine scope of patent protection by claims of being submitted to.
