Description

The blade lightning protection device of offshore wind turbine
【Technical field】
The present invention relates to the blade lightning protection device of offshore wind turbine.
【Background technology】
In view of sea climate environment has huge difference with land, thunder activities are more frequent, and lightning strike accident district occurred frequently is Raising aerogenerator unit safe, reduces the probability of lightning strike accident, it is to avoid unnecessary loss, improves unit anti-lightning energy Power, has invented a kind of new offshore wind farm turbines vane lightning protection conduction device.
Lightning protection device is generally provided with the blade of the land wind-driven generator of tradition, and the lightning protection dress on existing blade Put and a lightning protection ring is usually had on blade, when thunder and lightning hits blade arrester, lightning current is delivered to lightning protection ring, warp Cross lightning protection brush, earth cable guides to wheel hub lightning protection device, so far complete the earial drainage of thunder and lightning on blade, realize the biography of lightning current Lead.
Because root of blade lightning protection ring diameter is bigger than normal, it is oval it is impossible to make carbon brush surface uniform force.Tradition is done at present Method is that lightning protection brush slides on blade shell, during vane propeller-changing, due to the problems such as discontinuity and centrifugal force to anti- Thunder brush causes very big impact, causes lightning protection brush to come off so that lightning protection brush service life is short, needs often to change, impact is marine Unit safety.
【Content of the invention】
It is an object of the invention in place of overcoming the deficiencies in the prior art, providing a kind of structure simple, lightning protection effect is good, peace Dress is convenient, and carbon brush will not fall off, and carbon brush long service life, it is not necessary to frequent change, does not interfere with the sea of marine unit safety Wind power generation unit blade lightning protection device.
The object of the present invention is achieved like this:
The blade lightning protection device of offshore wind turbine, is characterized in that it includes the lightning protection ring being fixed on blade, institute The wheel hub of the Wind turbines stated is provided with lightning protection device fixed support, and the support bracket fastened other end is provided with shell fragment, shell fragment another End is provided with the lightning protection carbon brush contacting with lightning protection ring.
The blade lightning protection device of offshore wind turbine as above is it is characterised in that described shell fragment includes and solid The first connecting portion that fixed rack connects, the second connecting portion being connected with lightning protection carbon brush, and connect first connecting portion and second even The middle slanted bar of socket part, described first connecting portion, second connecting portion and middle slanted bar are a thin slice.
The blade lightning protection device of offshore wind turbine as above is it is characterised in that described shell fragment is propped up with fixing Frame is with bolts, and shell fragment and lightning protection carbon brush are also adopted by bolt connection.
The blade lightning protection device of offshore wind turbine as above is it is characterised in that described fixed support includes Stainless steel plate, stainless steel plate is connected with stainless steel stent, and shell fragment is fixed in stainless steel plate, and fixed support passes through not Rust steel bracket is connected with the wheel hub of Wind turbines.
Present configuration is simple, and lightning protection effect is good, easy for installation, and the toughness of carbon brush shell fragment is big, difficult for drop-off, can conduct 200KA lightning current, the wear-resistant cycle is long, and anti-marine salt mist corrosion problem is it is ensured that the safety of offshore wind farm unit.
【Brief description】
