Description
Technical field
This utility model is applied to technical field of wind power, relates to a kind of Novel wind power generator blade lightning protection connecting device.
Background technology
Along with the progress and development of society and progress and the wind power technology of wind power technology, wind power generating set power is increasing, therefore it is required that wind wheel height above sea level is more high, blade tactical diameter is more big, and each of which increases blade and suffer the probability of lightning risk. Traditional blade lightning protection mainly has two kinds of forms: one is be connected to wheel hub ground connection after being fixed directly or by steel wire rope by lightning protection wire, this structure in wind wheel rotary course during particularly vane propeller-changing lightning protection wire can be subject to very big tension-torsion power and wave in the confined space, cause the unstable wear of lightning protection wire even to rupture; Two is conducted electricity by structures such as carbon brush, there is very big operation risk in this structure, if carbon brush comes off, easily cause blade lightning protection and disconnect, lightning protection structure lost efficacy, and the tiny carbon dust produced after carbon brush abrasion can along with, in the electronics rotating into wheel hub and blade interior of wind wheel and mechanical part, causing the short circuit damage of electronic equipment or even the abrasion of equipment burnout and mechanical part without collecting mechanism.
Utility model content
Utility model purpose: in order to overcome above deficiency, the purpose of this utility model is to provide a kind of Novel wind power generator blade lightning protection connecting device, to improve life-span and the reliability of blade lightning protection device, it is ensured that the operation safety of wind-driven generator and simple-to-maintain.
Technical scheme: a kind of Novel wind power generator blade lightning protection connecting device, turns round stretch cord, lightning protection wire, wheel hub and quick change construction including blade root platform, tension; Tension is turned round the two ends of stretch cord and is connected respectively on blade root platform and wheel hub or support thereon by described quick change construction; Described lightning protection wire two ends are connected respectively on blade root platform and wheel hub or support thereon, and are wound on tension torsion stretch cord. This utility model is turned round on stretch cord by lightning protection wire is wound into the tension with high fatigability, can effectively reduce the distance produced due to parts manufacture, alignment error and change the impact caused, it is provided that again certain rigidity, prevent lightning protection wire from waving in wind and thunder rotary course, cause the abrasion of wire or the impact on other parts, improve lightning protection wire service life and reliability and the operation safety of wind-driven generator, and easy to maintenance.
Further, above-mentioned Novel wind power generator blade lightning protection connecting device, described tension is turned round stretch cord and is included at least one stretch cord, two joints, two snak links and band, tension turns round stretch cord under duplex type side by side configuration, being banded together by two stretch cords with band, stretch cord two ends connect snak link after compressing with joint. Need to realizing pretension when turning round stretch cord connection for tension and make it have certain rigidity, being banded together by two stretch cords with band is for convenience of safeguarding.
Further, above-mentioned Novel wind power generator blade lightning protection connecting device, described quick change construction is U-shaped or circular fixture, turns round the snak link at stretch cord two ends by connecting tension, its one end is fixed on blade root platform, and the other end is fixed on wheel hub or support thereon. By adopting the quick change construction with certain rotary freedom, it is prevented that blade produces tension in pitch process and turns round torsional deflection and the stress of stretch cord and lightning protection wire.
Further, above-mentioned Novel wind power generator blade lightning protection connecting device, described lightning protection wire one end is fastened on wheel hub, and other end pipe clamp is fixed on platform support, then is fastened on lightning-arrest junction block. Being likely to occur, at wire, the position sliding or particularly having with the parts with sharp-pointed corner with other parts contact slide adopts spiral protective sheath that it is protected, it is prevented that sliding or abrasion occurs in wire.
Further, above-mentioned Novel wind power generator blade lightning protection connecting device, described lightning protection wire two ends contact surface scribbles conductive paste layer, increases its electric conductivity.
Further, above-mentioned Novel wind power generator blade lightning protection connecting device, described lightning protection wire is wound into tension and turns round on stretch cord and bound by band. Can effectively reduce the distance produced due to parts manufacture, alignment error and change the impact caused, can prevent again blade from producing the phenomenon waved in rotary course.
Technique scheme can be seen that, this utility model has the advantages that Novel wind power generator blade lightning protection connecting device described in the utility model, can effectively reduce the distance produced due to parts manufacture, alignment error and change the impact caused, it is provided that again certain rigidity, prevent lightning protection wire from waving in wind and thunder rotary course, cause the abrasion of wire or the impact on other parts, improve lightning protection wire service life and reliability, and the operation safety of wind-driven generator, and easy to maintenance.
