<p>PURPOSE:To facilitate a combination of load with a power shaft on the ground and stoppage of a windmill under strong winds, by dislocating a horizontal windmill shaft and a vertical power shaft to some extent and coupling the power shaft, being installed to be descendible, with a rotation transmission mechanism, while carrying out displacement control against the direction of a wind with an adjust screw. CONSTITUTION:A windmill 10 rotates face-to-face with the direction of a wind by means of wind pressure received by a directional vane 12. In time of a light wind carrying a wind velocity of about 10m/s or less, as far as this condition continues, rotation of the windmill 10 or rotation of a horizontal windmill shaft 4 is speed up with a speed-up gear 7 and transmitted to an intermediate power shaft 6, then further transmitted to a vertical power shaft 2 via a bevel gear 8, driving a load 16. If the wind turns storng, a counteraction of wind pressure imposed on the windmill 10 on the one hand and the load 16 added to the power shaft 2 on the other hand grows larger than the force of an output adjust screw 13 so that the windmill 10 is displaced sidewards as bending the directional vane 12, thereby obviating the inmcrease of the rotating speed. Therefore it means that the speedier in wind velocity the larger in sideward displacement of the windmill 10. Likewise, when a brake 15 is applied, the power shaft 2 comes to stop and the windmill 10 is automatically displaced sidewards, losing its turning force whereby the windmill 10 can be stopped with a little braking force alone.</p> |
