Title:
VERTICAL SHAFT TURBINE AND BIDIRECTIONAL STACK TYPE VERTICAL SHAFT TURBINE PROVIDED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2012/044089
Kind Code:
A3
Abstract:
The present invention pertains to a vertical shaft turbine, which may extract valid energy at a low wind speed and at low rpm, and a bidirectional stack type vertical shaft turbine provided with the same, and provides a vertical shaft turbine, which comprises a composite blade section, an arm connected to the composite blade section, a rotational shaft connected to the arm, and a supporting body for supporting the rotational shaft. The composite blade section includes a cassette connected to the arm, a centrifugal rotational shaft rotatively coupled with the cassette, a first blade rotatively coupled with the centrifugal rotational shaft, a centrifugal force corresponding device coupled with the first blade, and a second blade coupled with the cassette. The first blade itself carries out rotational movement with respect to the centrifugal rotational shaft by a force which is generated in the centrifugal force corresponding device, which corresponds to the centrifugal force at the time of the rotation of the rotational shaft.
