<P>PROBLEM TO BE SOLVED: To solve a problem that need for "new energy" substitutive for fossil fuels and atomic power has been said for a long time; it is thought that natural wind power is good as solar heat wind power and efforts are concentrated in so-called wind power generation; this also depends on government subsidies similarly to a solar photocell; it is less efficient because of a propeller type; there is a construction at present in which upstanding rotary blades are installed on a top of a tower; and this is interesting but is improper because of a high center of gravity. <P>SOLUTION: A half-cylindrical blade windmill type wind power generator has a construction wherein a "half-cylindrical blade" type windmill, which is similar to a cup type windmill of a cup anemometer (Robinson's cup anemometer) and is formed by vertically installing four "half-cylinder" type blades each having a shape of a vertically halved cylinder and by clamping them with two discs or the like so that it works in a manner of the cup anemometer, is installed to be put on over a receiving shaft formed on a top of a tower, its lower disc is fitted in a tower body for rotation, an inner gear is installed on the lower disc, a follower gear is installed on a skin portion of the tower body, and a generator with a gear rotating through the follower gear is installed in the tower or outside the tower. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
