Working principle of the present invention is:
The utility model embodiment comprises employing frame 2, is rotatably installed in the wind wheel 1 of these both sides, frame top, is installed in the generator 3 in the described frame 2.
During wind wheel 1 proper functioning, fan blade 36 rotates to top gradually, fan blade elastic force positioning work piece 46 on the fan blade 36 is stopped by speed limiting device 37, top fan blade plane, 36 place and eolian plumbness, award wind area maximum, wind is to fan blade 36 active force maximums, when fan blade 36 rotates to the bottom gradually, fan blade 36 reverse side wind-engaging power effects, the fan blade elastic force positioning work piece 46 on the fan blade 36 rotates freely away from speed limiting device 37, bottom fan blade plane, 36 place and eolian parastate, award wind area minimum, wind is to fan blade 36 resistance minimums, and clockwise moment maximum is most effective.
In wind wheel 1 strong wind when work,, fan blade 36 rotates to top gradually, fan blade elastic force positioning work piece on the fan blade 36 46 is push-jump speed limiting device 37, and top fan blade plane, 36 place and eolian heeling condition have reduced the active force of wind to fan blade 36, have stablized rotating speed.
During the work of wind wheel 1 storm wind, fan blade 36 rotates to top gradually, wind action power slips over speed limiting device 37 greater than the elastic force of the fan blade elastic force positioning work piece 46 on the fan blade 36, the fan blade plane, 36 place and the eolian parastate that slip over, reduced the active force of wind to fan blade 36, prevented that rotating speed from continuing to increase, guaranteed the safety of unit.
When shutting down or installing; shake shaking of control unlatching gear-box 11 both sides and control flexible brush 10; this brush track 9 that shakes carbon brush head elongation contact brake disc 7 inboards of the flexible brush 10 of control makes circle raise machine 43 energisings; it is stressed and make speed limiting device 37 leave elastic force slurcocks 56 on the fan blade 36 to mind-set to shut down steel cable 42; all fan blades 36 are that the axle center rotates freely and the wind direction parastate with blade shaft 50; complete machine is active force without spin, and the break 6 braking brake discs 7 on the mate gear case 11 can be realized shutting down at any time.
The solar receiver of installing on the brake support frame 54 provides to shut down to enclose and has raised machine 43 needed power supplys.
Conical wind wheel spoke 39 is done very longly easily, makes the diameter of wind wheel 1 very long, has improved the rated power of unit.
The area on blade shaft 50 the right on the described fan blade 36 is little, the area on the left side is big, when having guaranteed that fan blade 36 rotates to top, fan blade elastic force positioning work piece 46 on the fan blade 36 is pushed speed limiting device 37 all the time to, when fan blade 36 rotates to the bottom, fan blade elastic force positioning work piece 46 on the fan blade 36 leaves speed limiting device 37 all the time, the cooperation by wind rudder 14 and the left side horizontal axis 8 of installation are offset reversing that gear-box 11 causes than right side horizontal axis 8 is long slightly, make under wind wheel 1 wind action in any direction, all can be by the direction rotation of setting.
