Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Shown in Fig. 1, it is structural representation of the present utility model; As we know from the figure, it comprises bearing 4, blade, speed regulator 2 and generator 1; Wherein, blade comprises sharf 8 and rectangular impeller 9, and rectangular impeller 9 is arranged on and is subject on wind wheel 10 that wind-force rotates by sharf 8 and bearing radial equipartition thereof; The two ends of sharf 8 are rotated and are connected with wheel carrier 10 by bearing respectively.For figure succinct, the bearing at sharf 8 two ends does not draw, just there is expression in Fig. 3.Wind wheel 10 forms a wind-power unit by the identical front wind wheel of structure and rear wind wheel, and front and back wind wheel is arranged on bearing 4 by central shaft 7 and bearing 6.From the broken section of the front and back wind wheel 10 of Fig. 1, also can see, rectangular impeller 9 is tilting with respect to the direction of the wind comes from right side, come together to see in conjunction with Fig. 2, the structural representation that in Fig. 2, A looks, making when the wind comes from right side, each blade of wind wheel 10 is subject to wind-force and rotates counterclockwise, and the rear wind wheel in left side is also subject to wind-force and rotates counterclockwise simultaneously.Described wind wheel 10 comprises central shaft 7, wheel carrier and blade, and wherein, wheel carrier is made up of interior ring stand 12 and outer ring stand 13, on the uniform tilting ring stand outside 13 of polylith blade radial.Known from Fig. 1 and Fig. 2, the interior ring stand 12 of wind wheel 10 wheel carriers is ventilation structure, and wind can blow to by the interior ring stand 12 of front wind wheel 10 blade of rear wind wheel 10, while making with rear wind wheel 10, rotates.After front wind wheel 10 and rear wind wheel 10 rotates, sequentially by central shaft 7, upper direction-changing drive mechanism 5, vertical pivot 3, lower direction-changing drive mechanism 11 and speed regulator 2, by power electric generator 1, the rotor of generator 1 is driven and is rotated generating.
Shown in Fig. 3, it is the structural representation that arranges of Fig. 1 and Fig. 2 middle period bobbin two ends force-limit spring; The two ends of sharf 8 are rotated and are connected with wheel carrier/wind wheel 10 by bearing 14, and the two ends of sharf 8 are all provided with force-limit spring 15, and the two ends of force-limit spring 15 are fixedly connected with wheel carrier or wind wheel 10 with sharf 8 respectively.Described force-limit spring 15 can limit certain torsion, and in the time exceeding the limit of force-limit spring 15, sharf 8 and rectangular impeller 9---blade rotation thereof, reduce windward side, and energy venting part wind-force, avoids the damage of strong wind.
