Abstract

PROBLEM TO BE SOLVED: To provide wave activated impeller power generation capable of performing large capacity wave activated power generation by a large number of waves by converting the wave power to the rotational force of a generator shaft at any point on a major axis parallel with a coast as long as the vertical (longitudinal) motions of the waves occur. SOLUTION: A large number of blades 2 with the same or different diameters and lengths are radially fitted to the major axis 1 connected to the rotating shaft of a power generator. These blades are cut out laterally, and the end faces thereof are joined with each other, in order in the same direction, for example, through special hinges 13 so as to be bent in a specified direction but not opened in a reverse direction more than horizontal. When the major axis is held parallel with the wave so as to be rotated under the wave, even if the waves coming from offshore are nonuniform, as long as the vertical (longitudinal) motions 4 and 5 occur, the pair of horizontal blades are rotated due to a difference in pressure receiving area caused since one horizontal blade is not broken when the waves rise and the other is broken when the waves rise. This event also occurs reversely when the waves lower, but the rotating direction is kept unchanged, and a smooth rotational force in a specified direction occurs on the major axis at all times by a blade length suitable for the wave lengths.

These wings are cut laterally, and one side of each wing is sequentially folded in the same direction in a fixed direction, but is connected in a reverse direction by, for example, a special hinge or the like so as not to open more than horizontal.
If this long axis is held so that it can be rotated below it in parallel with the waves, even if the waves coming from offshore are uneven, as long as there is vertical (front-to-back) flow, the waves will rise on the pair of horizontal wings Occasionally, the hinge of one of the determined horizontal wings does not break because the hinge withstands the water pressure, and the pair of wings breaks and rotates with a difference in the pressure receiving area. When the wave descends, the pair of wings breaks in the opposite direction, but the rotation direction does not change. Further, due to the wing length suitable for the wavelength, a smooth rotating force is always generated in the long axis on the long axis. In other words, even if many waves rushing to the long axis are irregular, as long as they flow up and down (back and forth), the shaft is always rotated in the same direction, and the energy of each small wave is widely collected to economically increase. Capable of generating wave power.

The fan is turned to generate electricity.
In this method, even if the cylinder is large, if there are a large number of waves in the large cylinder, the air on the waves cancel each other out, and the averaged amount of air to be sucked and discharged does not increase. According to the present invention, a large-capacity power generation is performed by collecting all of these energies and constantly rotating the shaft in a fixed direction, as long as all the waves of irregular sizes that come to the major axis have a vertical (front-to-back) flow. Can be performed.

する装置も含まれる。1. A large number of blades (2) having the same or different diameters and lengths are radially mounted on a major axis (1) connected to a rotating shaft of a generator. These are cut laterally, and one side of them is sequentially broken in the same direction in the predetermined direction, but in the opposite direction, for example, a special hinge (3) so as not to open more than horizontal.
And so on. If this major axis is held so that it can be rotated below it, parallel to the waves, the waves rushing from offshore will have an upper (4) lower (5) ｛front (6) after (7)｝ flow even if it is uneven As long as one pair of horizontal wings does not break during the wave rise (4), the other half of the pair breaks,
Rotation occurs with a difference in the pressure receiving area. Wave descent (5)
Sometimes the opposite occurs, but the direction of rotation does not change. Further, due to the blade length suitable for the wavelength, a smooth rotational force in a constant direction is always generated on the long axis (1). With this device, a large amount of wave energy can be economically collected by collecting a large amount of energy of each small wave. Devices that partially cut these wings and connect them in the same manner, and devices that fix, for example, umbrellas to the wings (rods), which open for upward flow and close for reverse downward flow, are also included.
