Description
Technical field
The utility model belongs to the renewable energy source domain, be specifically related to a kind of novel anti ocean environment corrosion wind-driven generator steering equipment that adopts nonmetal-metallic material combination, this mechanism has the ability that anti-salt erosion, UV-b radiation, thunderbolt etc. destroy, and has improved life-span and the reliability of wind-driven generator in ocean environment greatly.
Background technique
International energy crisis and lasting environmental deterioration make the numerous and confused exploitation dynamics that strengthens emerging renewable energy sources in various countries, and wind-power electricity generation is the clean energy resource that the most potential part substitutes traditional fossil energy.In China, wind-power electricity generation is the most real selection of the energy and the electric power strategy of sustainable development.At present, China hastens towards saturation land wind energy development day, and wind energy on the sea has become the focus of next step Wind Power Utilization.Different with land wind energy, wind energy on the sea need face abominable ocean strong corrosive environment, destructions such as marine salt fog, ultraviolet ray, thunderbolt are several times as much as the hinterland, internally land wind machine metal steering bearing has the catastrophic collapse ability, at present the wind-driven generator knuckle section is as steering equipment by main shaft plane pressure bearing and three-phase slip-ring, the applanation rotary bearing is difficult to long-time reliably working in the marine corrosion environment, safeguard very difficulty, and is costly.This also is that landlocked blower fan can not be in the key factor of coastal area reliably working, therefore we have designed the special-purpose steering equipment of coastal blower fan of a kind of brand new metal and nonmetal combination, saved expensive steering bearing, solved the shortcoming that ocean environment wind-driven generator steering system is difficult to reliably working, the development and use of marine wind energy have been played a role in promoting.
Summary of the invention:
The purpose of body model utility provides a kind of novel wind generator steering equipment, and reliable operation simple in structure has anti-ocean environment destruction characteristic simultaneously, has prolonged the working life of ocean blower fan greatly, reduces maintenance cost.
The technical solution of the utility model is:
Adopt nylon, poly-tetrafluoro to form the nonmetallic bearing group and replace the Metal Ball main bearing.The nonmetallic bearing group is by the axial swivel bearing of four strata tetrafluoro running shaft rims conduct, poly-tetrafluoro Bearing Installation is on blower fan supporting post upper end cap, be enclosed within on the upper end cap transmission of electricity three-phase slip-ring, the transmission of electricity slip ring is fixed on upper end cap, and transmission cable hangs down by upper end cap in the supporting post.The conduct of twice nylon column bearing is swivel bearing radially, be installed in main supporting post upper end, under upper end cap, another road is on main supporting post lower limit ring together, main supporting post lower limit ring and upper end cap be at a distance of 1.5 meters, works to limit urceolus and deviate from and bear radial force.Upper end cap and lower limit ring are equipped with leads the thunder bar and links to each other with the base plate rotating cylinder, as thunder and lightning bleed off passage.The blower fan supporting post inserts the base plate rotating cylinder, links to each other by gathering tetrafluoro bearing, nylon roller bearing, limited ring and leading the thunder bar.Teflon friction factor 0.04, the acid-and base-resisting corrosion, temperature characteristic is fabulous, and because wind-powered electricity generation unit tuning speed is comparatively slow, therefore poly-tetrafluoro can be used as cod sheet good under the rugged environment.Wind-powered electricity generation unit bearing not only will be born axial force, also will bear radial force, the present invention has designed radially nylon roller bearing, bears the blower fan radial force, utilize supporting post and base plate rotating cylinder will gather the tetrafluoro bearing plate and the nylon roller bearing is installed together, and designed the special thunder bleed off passage of leading.Since poly-tetrafluoro and nylon under ocean environment, does not almost have corrosion with self preferably low coefficient of friction formed unique nonmetallic bearing group, under ocean environment, almost have the unlimited life-span, and cost is much lower than metal bearing, having good and economic and reliability, is the optimal selection that substitutes the conventional metals bearing.
