Abstract

[PROBLEMS] To provide a device that converts a continuous rotational motion in one direction regardless of the direction of the tidal current, has a simple structure, can be miniaturized, and efficiently captures the tidal current and increases the rotational force. A movable blade water turbine tidal current power generation apparatus, the main part of which is composed of a plurality of circular horizontal blades 12, excluding the lowermost horizontal blade, and a movable blade 14 below the horizontal blade 12 is provided. The interval between the horizontal blades 12 is set to a width that allows the movable blades 14 to be perpendicular to the horizontal blades 12, and the number of movable blades 14 increases or decreases depending on the size of the horizontal blades 12. The rotary shaft 15 is mounted on the lower side of the ridge so as to be perpendicular to the seabed, continuously rotates in one direction regardless of the direction of the tidal current, and operates the generator installed on the upper portion of the ridge.

Japanese Unexamined Patent Publication No. 2015-48843

Problems that the device tries to solve

  Conventional tidal current power generation is often of a propeller type and requires a device that responds to the direction of the tidal current, and the generator is also installed in the sea, so measures for waterproofing, salt damage, and maintenance management have not been easy.

Means to solve the problem

  In order to solve the above problem, a generator is installed at the top of the sea basin, and the movable vane turbine is mounted on the underside of the basin, and the rotary axis of the movable vane turbine is perpendicular to the seabed. By devising a movable impeller that can rotate continuously in one direction, the structure is extremely simple and maintenance is easy.

Effect of device

  The device for converting the tidal current according to the present invention into a continuous rotational motion in one direction regardless of the direction is simple in structure and can be miniaturized. By using a movable impeller water turbine, the tidal current can be captured more efficiently than a propeller type to increase the rotational force. I was able to do it. Easy to manage and can reduce construction costs

  It is a figure which shows the whole of this apparatus, and is a figure which shows the state which suspends a weight via the pulley attached to the flame | frame of the lower side of a ridge with a wire from two bases of the seabed, and maintains a stable position.   It is a sketch of a movable blade water wheel.   The upper figure shows a state where the movable blade receives and opens the tidal current at an angle perpendicular to the horizontal blade, and the lower figure shows a state where the movable blade is pushed up by the force of the tidal current.

Hereinafter, embodiments according to the present invention will be described with reference to the drawings.

FIG. 1 shows a structure in which a base 1 base 2 is fixed so as to be parallel to a tidal current in accordance with the water depth on the seabed, a wire 5 is connected to the base 1 and a pulley 3 is attached to a frame 8 below a coral 10 on the sea. The weight 7 is suspended, the wire 6 connected to the base 2 is suspended via the pulley 4 attached to the frame 8, and the entire shaft 10 is used as a device for maintaining a stable position. Is installed so that it is perpendicular to the seabed, and continuously rotates in one direction even if the direction of the tidal current changes. If a tidal current occurs, the tidal current is captured efficiently and continuously rotated to operate the generator.
FIG. 2 shows a state in which the movable blade 14 is opened and closed when the tidal current flows from the front to the front of the movable blade turbine 9. When the movable blade 14 is fully opened, the angle is perpendicular to the horizontal blade 12, and the tidal current is up and down. The horizontal vane 12 and the vane support plate 13 on the rotating shaft 15 side seal the escape area to increase the rotational force, and the movable vane on the side against the tidal current is closed by the tidal current to minimize the resistance surface and minimize the negative surface as efficiently as possible. I made it rotate.
FIG. 3 shows a state where the movable blade 14 is perpendicular to the horizontal blade 12 due to the tidal current, and the lower diagram shows a state where the movable blade 14 is closing due to the tidal current.

  The present invention can be used not only for tidal currents but also for rivers, and movable blades can also be used as windmills, and has a structure that continuously rotates in one direction regardless of the wind direction.
