Abstract
PURPOSE: To make a coning angle variable by wind pressure working on blades and prevent excessive rotation by inclinably supporting blades of a windmill, used for a windforce heat generation device etc., and at the same time energizing the blades toward the upper course of the wind to make a slanting motion by means of an elastic body.
CONSTITUTION: A wind force heat generation device transmits rotation of a blade D by wind force to a main shaft 3 through hub 24 and, after its acceleration by an accelerating gear mechanism 4, transmits it to a heat generator 5 and causes the watr in the equipment 5 to generate heat, subsequently recovers this water as warm water. In this case, the blade D is the coning angle as it is reduced to small degrees of an angle of about 5° by spring tension of a coil spring 41. In case the wind speed grows more than predetermined one and wind pressure working on the blade D becomes larger than spring tension of the spring 41, the blade D is inclined to the lower course of the wind around a pin 29. At the same time, by shitting a disc 21 to the right together with a rod 19 through connecting rods 36, 31, 33 in order to compress the spring 41, the blade D is fixed at a position where the wind pressure is well balanced with tension of the spring 41.
