Abstract
The present application discloses a power generation device so as to solve the generator set overspeed problem. The power generation device comprises: a stand column; and at least one generator set located on the stand column. The generator set comprises a support, blades connected to the support, and a power generator generating power by means of rotation of the blades, and an adjustment device located on the support and used for adjusting a windage area of the blades by moving or rotating the blade according to a wind speed. The wind power generation device may reduce an effective windage area to zero when the wind force is too high, thereby improving stability and applicability in a changeable environment and prolonging the service life of the apparatus.
Claims17
A power generation device, comprising:
- a stand column;
- and
- at least one generator set located on the stand column, wherein each one of said at least one generator set comprises a support, a plurality of blades connected to the support, and a power generator generating power by means of rotation of the plurality of blades,
- wherein each of said at least one generator set further comprises an adjustment device, the adjustment device is located on the support and configured to adjust a windage area of the plurality of blades by moving or rotating the plurality of blades according to a wind speed,
- wherein one of the at least one generator set further comprises a plurality of blade cabins arranged in an array distributed along a circumference direction of the stand column, and each of plurality of blade cabins is of barrel shape and extends in a radial direction of the stand column, and said one of the at least one generator set has a closed streamline surface when the plurality of blades are retracted into the plurality of blade cabins, respectively.
A power generation device, comprising:
- a stand column;
- and
- at least one generator set located on the stand column, wherein each one of said at least one generator set comprises a support, a plurality of blades connected to the support, and a power generator generating power by means of rotation of the plurality of blades,
- wherein each of said at least one generator set further comprises an adjustment device, the adjustment device is located on the support and configured to adjust a windage area of the plurality of blades by moving or rotating the plurality of blades according to a wind speed,
- wherein each of the plurality of blades is designed in a sectional type, a first section of one of the plurality of blades is proximal to the support, a second section of said one of the plurality of blades is distal from the support, a diameter of a cross section of the first section of said one of the plurality of blades is less than that of a cross section of the second section of said one of the plurality of blades, the first section and the second section of one of said plurality of blades is of a bent circular-pipe shape partially cut in a longitudinal direction, and a slope-shaped, arc-shaped or step-shaped transition section is arranged between the first section and the second section of said one of the plurality of blades, an edge of a front end of the second section is capable of being buckled and attached to the transition section of an adjacent one the plurality of blades, so that a streamlined circular-ring-shaped housing is formed by the plurality of blades in folded state and the first section is positioned inside the streamlined circular-ring-shaped housing when the plurality of blades are folded completely.
