Description

Tower-type turbine wind power generation device

Art

The present invention relates to one and extensively can be useful in the tower-type turbine wind power generation device that all kinds of wind territory produces wind-powered electricity generation and control windburn (calamity).

Background technique

At present, develop this natural, clean renewable wind energy resources is not only the common recognition of countries in the world, the craving for of the mankind only not, the workable reserves of wind energy of being bestowed by heaven is very huge, if can effective exploitation wherein 1%, then global energy resource structure will great changes will take place, coal, these non-renewable resources of oil no longer will be mainly used in generating, the fuel of power equipment, in ecotope, carbon emission amount also will significantly reduce, in the overall situation of this urgent need, wind-powered electricity generation is produced and is grown with each passing day, the rotary propeller type wind generator dropping into practicality as is well known, because overall structure is only suitable for enriching at wind energy resources, wind speed, wind direction meets designing requirement, wind territory without sudden strong wind is set up large-scale, super sized type wind turbine is mined massively collection wind-powered electricity generation, revolve the noise produced when oar rotates to exceed standard far away, have to away from cities and towns, windburn can not be defendd and adapt to the requirement that when wind speed changes greatly, generated energy also changes thereupon, make Shortcomings in the popularity of all kinds of wind territory exploitation wind-powered electricity generation.

Summary of the invention

Tower-type turbine wind power generation device provided by the invention is that one does not affect by wind speed, wind direction, one tower configuration multiple stage DC generator adapts to generated energy when wind speed changes and also changes accordingly thereupon, large-scale, super sized type wind-powered electricity generation system can be set up in all kinds of wind territory, divide 4 grades, A is small-sized, turbine diameter 8 meters, design maximum tower height 32 meters, balanced configuration two groups totally 4 DC generator in machine room, maximum total installation of generating capacity 500KW, arranged in arrays plays " sand-break " effect there being flowing sand damage leading edge wind-force to reduce surface layer wind speed; B is medium-sized, turbine diameter 16 meters, design maximum tower height 64 meters, balanced configuration two groups of 4 DC generator in machine room, and maximum total installation of generating capacity 5000KW, can drive the strong wind of more than speed per hour 100KM when tower height is set as 32 meters, be suitable for developing wind power resources in all kinds of wind territory; Above-mentioned two kinds all by Modular design newel and wind turbine standard paragraphs assembling parts, tower height can make design modifying with meteorological data, can move; C is large-scale, turbine diameter 32 meters, D super sized type, and turbine diameter more than 64 meters, because of system complex, discomfort is discussed in this article.

The object of the present invention is achieved like this, a kind of tower-type turbine wind power generation device, at the outer sheathed concentric wind turbine sleeve of newel, shaft end establishes 45 ° of umbrella gear dishes and 4 driven bevel gears to connect with DC generator through bearing support, clutch, gearbox respectively, completes kinetic energy (E=1/2MV ²) be converted to mechanical energy, flow process that electric energy exports through transformation and distribution system; The concentric sleeve of wind turbine and top cover are the solid of rotation that combine as a whole is 80 ~ 100 millimeters at tower top by the gap of rolling ball support and newel, with spin body shared gravity load on the pedestal roller bearing device that cover shaft end 45 ° of umbrella gear dishes are arranged on adjustable turbine solid of rotation gravity load; Turbine vane is that semi-cylindrical Varied section hollow arc impeller and sleeve are connected into cylndrical surface streamline cavity that three head and the tail are connected and form the turbine that eternal same direction rotates around newel, and such trisection cylndrical surface moment of rotation is large, noise is little, structure is simple and direct.The turbine that triangle housing and sleeve that inside and outside wheel blade, coverboard face is formed are integrated into mechanical structure very stable is overall, establishes strengthening rib and filling high-strength polyester foamed makes turbine solid of rotation tighter firm in leaf shell; Two groups of symmetrical 4 bearing supports are the support of affiliated driven bevel pinion transmission and " jig " immovable point of fixing driving bevel gear dish, clutch is by computer control, a DC generator job is connected during wind intensity 3 ~ 4 grades, one group of two machine work of its symmetry are made when 5 ~ 7 grades, when 8 ~ 12 grades, two groups of 4 DC generator all put into operation, and adapt to the generated energy when wind speed changes and also change thereupon; Adopting the concentrating type such as array, matrix to deploy troops on garrison duty in the mechanism having windburn area to resist disaster caused by a windstorm is the drop-out value calculating surface layer wind speed in zone of protection after stopping with physical mechanical methods such as " law of conservation of energy " " kinetic energy formulas ", just reaches the object of mitigation when it is less than disaster wind speed.
