<p>The present invention relates a blade pitch controlling device of a small wind power generator, more specifically, to a blade pitch controlling device of a small wind power generator capable of consistently generating power by continuously maintaining the rotating power of the required blade by automatically controlling the blade pitch by using the pitch adjusting piece and a pitch control cylinder. To this end, the present invention comprises multiple moving pieces which are integrally formed on the outer circumferential surface of the forward and backward moving part, have a movement groove in the center, and move along with the forward and backward moving part; a pitch adjusting piece which has a tripod shape, has an adjusting pin which is each inserted into the movement groove in the end of the pitch adjusting piece, has a key groove into which a blade shaft is inserted and fixed in the center, and changes the angle of blade pitch while the angle is changed when the forward and backward moving part moves forward and backward; and a pitch adjusting cylinder which is hinged and coupled to the fixing piece which is formed on the side surface of the end of the pitch adjusting piece so as to be located adjacent to the vicinity of the adjusting piece, is compressed when the forward and backward moving part moves backward, and causes the pitch adjusting piece to return to the original state after compression.</p> |
