Embodiment
See Fig. 2, Fig. 3 and Fig. 4, the utility model blade wheel structure comprises wheel hub 10, blade 20, active connection and Returnning spring 40, wheel hub 10 is installed on the wheel shaft 50 of blower fan by shaft sleeve part 11 also can drive wheel shaft 50 synchronous axial system, be rotationally connected by active connection between wheel hub 10 and blade 20, active connection is Flexible Connector 31, see Fig. 5, Fig. 6 and Fig. 7, Flexible Connector 31 comprises wheel hub joint 311 and blade joint 312, wheel hub joint 311 is angle bending with blade joint 312 and connects into entirety, angle between wheel hub joint 311 and blade joint 312 is α, the effect of this angle α makes blade have individual torsional angle after becoming oar, produce resistance at vane rotary process Leaf thus suppress rotating speed, wheel hub 10, blade 20 have Baltimore groove with the connecting end of Flexible Connector 31, and the wheel hub joint 311 of Flexible Connector 31, blade joint 312 are flush-mounted in respectively after in Baltimore groove and are locked with wheel hub 10, blade 20 by the first bolt 61, first nut 62, the upwind side that Returnning spring 40 one end is fixedly connected on the outer wall of the shaft sleeve part 11 of wheel hub 10, the other end is connected to blade 20, wherein, Flexible Connector 31 is preferably rubber parts.When rated wind speed, blade 20 keeps design angle under the effect of Returnning spring 40 and between wheel hub 10, the blade 20 by wind impetus when wind speed exceedes rated wind speed, and owing to being connected by Flexible Connector 31 between blade 20 with wheel hub 10, therefore Flexible Connector 31 produces deformation thus realizes the Windward angle of blade 20 and the automatic adjustment of wind-exposuring area.
Active connection can also be hinge means 32, see Fig. 8, hinge means 32 comprises the first hinge plate 321 and the second hinge plate 322, first hinge plate 321 is installed on wheel hub 10 by the second bolt 63, second nut 64, second hinge plate 322 is installed on blade 20 by the 3rd bolt 65, the 3rd nut 66, is rotationally connected between the first hinge plate 321, second hinge plate 322 by rotatingshaft 323; The hinge plate mounting end of wheel hub 10, the hinge plate mounting end of blade 20 have L shape groove, first hinge plate 321, second hinge plate 322 is installed in the L shape groove of wheel hub, blade respectively, second bolt 63 is locked through being threaded with the second nut 64 after wheel hub 10, first hinge 321 plate successively, and the 3rd bolt 65 is locked through being threaded with the 3rd nut 65 after blade 20, second hinge plate 322 successively; When wind speed exceedes rated wind speed, blade 20 by wind promotes drive second hinge plate 322 moving axis 323 that rotates and rotates thus realize the Windward angle of blade 20 and the automatic adjustment of wind-exposuring area.
In accompanying drawing, A is to being wind direction.
After adopting blade wheel structure of the present utility model, the power of rated wind speed section that it has before guarantee and the basis of rotating speed effectively can control high wind speed section rotating speed, make it can effective output power very well in high wind speed section, considerably increase generated output and increase applicable wind speed range; Meanwhile, the propeller pitch angle of blade can be changed and wind-exposuring area makes the load of wind wheel to generator reduce and reduces pylon load in high wind speed section; And blade can make its zero response time recover corresponding state under the action of the spring, thus increase generating efficiency; In addition blade structure of the present utility model is lower to the requirement of generator in vane propeller-changing adjustment process, thus also effectively can reduce the operating cost that automatically controlled cost also finally can reduce wind-driven generator.
