Summary of the invention
The object of this invention is to provide a kind of spur rack formula wind wheel blade controlling mechanism, overcome deficiency of the prior art, change blade adjustments mode, blade adjustments is realized synchronous, reduce regular maintenance cost, make wind speed that scope can be utilized significantly broadening, improve generating efficiency.
Technological scheme of the present invention comprises the power unit that major axis horizontal is arranged; Also comprise drive motor fixed tray, cabin cylindrical wall, shroud fixed by tooth bar, hub disk fixed by tooth bar, front platen, rear platen, pinion and rack, screw-nut body, sliding pole axis bearing, slide bar bearing, slide bar;
Cabin cylindrical wall is dodecagon cylinder, front platen is connected on drive motor fixed tray, cabin cylindrical wall is arranged between front platen and rear platen, cabin cylindrical wall is provided with the hole of the assembling sharf that 12 are evenly arranged, three sliding pole axis bearings are evenly arranged on rear platen, three slide bars be evenly arranged are fixed on tooth bar by slide bar bearing fix shroud and tooth bar is fixed on hub disk through sliding pole axis bearings, 12 toothed rack are evenly fixed on tooth bar fixes shroud and tooth bar is fixed between hub disk, sharf is arranged on the cylindrical wall of cabin by bearing, the sharf end that gear is fixed on cabin inside cylinder wall is formed with tooth bar engages, nut is fixed on tooth bar fixes shroud central authorities, leading screw and nut are formed and coordinate and be connected with the output mechanism of power unit.
Further, the power unit of described blade control device adopts motor.
The present invention has following beneficial effect: the present invention adopts screw-nut body and rack and pinion drive mechanism, change blade adjustments mode, make adjustment of blade angle synchronous, and make the adjusting angle of blade easily control with stable, the use in low wind speed and high wind speed region can be met simultaneously, improve the wind energy utilization efficiency of blower fan, increase complete machine output power, thus reduce the cost of unit generated output; Solve that prior art Three-blade horizontal axis wind-driven generator output power is difficult to further increase, blower fan can utilize the problems such as wind speed range is narrower, adjustment of blade angle is asynchronous.The technology of the present invention feature structure is compact, and volume is little, lightweight, velocity ratio large, and improve propeller regulating mechanism, simple and reasonable, loss is less, reduces rate of fault, facilitates regular maintenance, maintenance.
Below in conjunction with drawings and Examples, summary of the invention of the present invention is further described.
