Background technique
Utilize the abundant wind energy resources generating of nature, the technical problem of its core is to improve wind energy to the energy conversion efficiency of electric energy, also will rationally establish mechanism's meter structure, makes generating drive wind speed rank to reduce.In prior art, horizontal shaft type three blade wind motor for electric generation simple structures and with low cost, but energy conversion efficiency is low, causes the turnover long, lacks the attraction force that investment utilizes; Main shaft longitudinal wind generating unit transformation efficiency is higher than horizontal shaft type three blade wind motor for electric generations, but its Structural Tectonics is comparatively complicated, medium-sized and large-scale wind generating unit particularly, mechanism is bulky, main shaft load is heavy, operating noise is large, wind speed need to reach higher level special talent can drive generating, thereby can only be applied to the wind energy the most remote place such as air port, mountain area, island; In addition, in generating work, Pneumatic wheel can drive main shaft upper end to occur that stress rocks distortion, both dangerous, has also affected drive connection good between main shaft and generator, even can stuck drive connection, cause the job failure that cannot generate electricity.
Summary of the invention
Goal of the invention of the present utility model be effectively to reduce wind-drive running generating rank, provide a kind of slow wind scale of longitudinal that is more suitable for being applied to medium-sized and large-scale wind generating to drive wind generating unit.The slow wind scale of longitudinal that the utility model provides drives wind generating unit technological scheme, its main technical content is: the slow wind scale of a kind of longitudinal drives wind generating unit, the longitudinal rotational support of main shaft of its Pneumatic wheel is arranged between the center upper portion bearing of base and supporting tripods, transmission joint between the indoor generator of main shaft and base-plate engine, some groups of wind blades are centered by main shaft evenly outwards on the radial center stack frame that is fixedly assemblied in main shaft, anchor balancing band position the be provided with magnetic corresponding with base of Pneumatic wheel bottom surface is to scolding slide rail ring, described magnetic is by being assembled in respectively base and Pneumatic wheel bottom surface to scolding slip ring, the relative magnet ring of same polarity forms.Described supporting tripods wherein is also not only confined to Three-legged support frame, also comprises other multiway support frame and fixing support rack.
In above-mentioned overall technical architecture, on each described wind blades, be placed with windward mouthful and go for a drive recessedly towards consistent, the recessed mouthful width windward that goes for a drive is not more than the maximum lateral width of the recessed inner chamber of arc.
The slow wind scale of the disclosed longitudinal of the utility model drives the technological scheme of wind generating unit, by magnetic to scolding the magnetic repulsion amount of slip ring to offset significantly Pneumatic wheel load-carrying, the wind that greatly reduces Pneumatic wheel drives resistance and main shaft and driving mechanism load, the moving frictional loss coordinating of device significantly reduces, both it is medium-sized having made, large-scale wind generating unit, also can be blown by little rank wind speed, implement effectively generating, break through existing apparatus technology and installed and used the limitation of environmental conditions, increased the utilization ratio of natural wind energy, turnover shortens, strengthened the attraction force that investment utilizes, device overall structure is stable, reliably, especially guaranteed the continual and steady operation of driving mechanism, extend the working life of this electricity generating device, noise is low.The technical program also has that energy conversion efficiency is high, simple structure, technological merit that cost cost is low.
