Abstract

Disclosed herein is a variable blade type tidal and wind power generator with increased generation efficiency. The tidal and wind power generator includes an installation frame (10), a vertical rotating shaft (20), blade installation bars (30) and (30′), support rings (40) and (40′), vertical support rods (50); rotor blades (60) and (60′), vertical support frames (70), horizontal frames (80), an installation member (20′), a support wire (50′), a blade-spreading-degree control means (90), a generation efficiency enhancing means (100) and a generation means (200) which is coupled to the lower end of the vertical rotating shaft to generate power. The tidal and wind power generator can be operated even in conditions of gentle winds or low tides regardless of the direction of the wind or the tidal flow.

A variable blade type tidal and wind power generator with increased generation efficiency, comprising:

an installation frame (10) having a ‘+’-shaped structure and placed on a base surface, with a vertical-rotating-shaft support bracket provided on a central portion of the installation frame (10);
a vertical rotating shaft (20) rotatably provided upright in the central portion of the installation frame (10);
a plurality of blade installation bars (30) and (30′) crossing upper and lower portions of the vertical rotating shaft (20) in directions perpendicular to the vertical rotating shaft (20), the blade installation bars (30), (30′) being spaced apart from each other at regular angular intervals;
a plurality of support rings (40) and (40′) each of which connects ends of the corresponding blade installation bars (30), (30′) to each other;
a plurality of vertical support rods (50) respectively connect the ends of the corresponding upper and lower blade installation bars (30) and (30′) to each other;
a plurality of rotor blades (60) and (60′) installed between the blade installation bars (30) and (30′) by means of brackets;
a plurality of vertical support frames (70) installed upright on outer ends of the installation frame (10);
a plurality of horizontal frames (80) connected to upper ends of the respective vertical support frames (70);
a support wire (50′) connecting an installation member (20′) provided on an upper end of the vertical rotating shaft (20) to the ends of the blade installation bars (30) so as to support the blade installation bars (30);
a blade-spreading-degree control means (90) provided under lower surfaces of the blade installation bars (30′), the blade-spreading-degree control means (90) controlling angles at which the rotor blades (60) and (60′) spread;
a generation efficiency enhancing means (100) provided under a central portion of the installation frame (10), the generation efficiency enhancing means (100) for changing the number of turbines operating to generate electricity depending on a magnitude of wind;
and
a generation means (200) provided under a lower end of the vertical rotating shaft (20), the generation means (200) for generating electricity.
