本発明は傾斜筒を用いた波力発電装置に関し特
に海水抵抗が少なく、大きな海水動揺が得られる
傾斜筒を用い、効率よく発電することができる波
力発電装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wave power generation device using a tilted tube, and more particularly to a wave power generation device that can efficiently generate power using a tilted tube that has little seawater resistance and can generate large seawater agitation.
海面を貫いて、両端を開放して斜設された円筒

内の海水の固有周期を海面波の周期と同調させ
て、大振巾の海水動揺を得、円筒内のプロペラタ
ービンをこの海水動揺の力によつて回転させる方
法は知られている。 By changing the inclination angle and submerged length of a cylinder that penetrates the sea surface and is installed diagonally with both ends open, the natural period of the seawater inside the cylinder can be synchronized with the period of the sea surface waves, resulting in large-scale seawater agitation. A method is known in which a cylindrical propeller turbine is rotated by the force of this seawater agitation.

円筒２を垂直軸Ｚに対してθの傾斜角度をもつて
海水に半没させた場合、円筒２の水没長さをと
すると円筒２内の海水の固有周期T0は次式で表
すことができる。 Figure 1 is a diagram explaining the principle of wave power generation.
When the cylinder 2 is half submerged in seawater at an inclination angle of θ with respect to the vertical axis Z, the natural period T 0 of the seawater inside the cylinder 2 can be expressed as the following equation, where the submerged length of the cylinder 2 is can.
T0＝２π√ｇ・
（ただし、ｇは重力加速度）
このとき、海面波の周期が円筒内の海水の固有
周期に一致すると円筒内の海水は共振して大振巾

よつてこれを回転させ、発電をすることができる
のである。T 0 =2π√g· (where g is gravitational acceleration) At this time, when the period of the sea surface wave matches the natural period of the seawater inside the cylinder, the seawater inside the cylinder resonates and causes a large amplitude interlock. Therefore, a variable pitch propeller turbine is placed inside this cylinder, which can be rotated by the force of seawater movement to generate electricity.

よい。 Various methods have been considered to change the natural period of the seawater inside the cylinder and synchronize it with the sea surface waves. The return method is efficient.

が、この方法は可撓管継手の部分で折線を生じ、
海水抵抗が増すという欠点があつた。 A method has already been proposed in which the spindle is provided at the submerged end of the cylinder and the turbine is installed in the middle of the cylinder, but this method causes the position of the turbine to move up and down as the cylinder moves up and down. The drawback was that the generator itself had to be floated on the sea surface and installed so that it could swing freely. In addition, the submerged end of the cylinder is fixed to the legs of the platform, and when the cylinder moves up and down,
In order to prevent the position of the turbine from changing, it has been considered to make the cylinder at the turbine mounting position a flexible tube, but this method causes a break line at the flexible tube joint.
The drawback was that seawater resistance increased.
本発明者らは、このような欠点を解消するため
鋭意検討を重ねた結果、次のような本発明に至つ

に特徴を有する。 That is, in the present invention, a generator is mounted on a platform and is driven from a rotating shaft of a variable pitch propeller turbine (described later) via a power transmission mechanism.
In addition, a cylinder with both ends open is attached to the leg of the platform, diagonally half-submerged in seawater, and the natural period of seawater vibration inside the cylinder is adjusted by changing the inclination angle and submerged length of the cylinder. The position where the turbine is installed in a wave power generation device that generates electricity by generating large-scale seawater agitation by synchronizing it with the cycle of sea surface waves and rotating a variable pitch propeller turbine installed in the cylinder. The cylinder is rotatably supported on a platform by a hollow support shaft, and a power transmission shaft for transmitting the rotation of the turbine to the generator is passed through the hollow support shaft. It is characterized by the points arranged as follows.

The other point of the cylinder is suspended by a wire 4, and the wire 4 is wound around a hoisting drum 5, which is rotated by a drive motor 6. The drive motor 6 is also fixed to the platform 1.

It is pivoted so that it can rotate freely. The propeller turbine 7 is rotated by a bevel gear 11.
The rotation is transmitted to the horizontal transmission shaft 13 passing through the support shaft 3, and further transmitted to the vertical transmission shaft 8 by another set of bevel gears 14. The propeller turbine has a variable pitch structure, so it always rotates in the same direction no matter which direction the seawater moves from. The propeller turbine has a streamlined stay 15

達し、発電が行なわれる。 The chain line in FIG. 2 shows the position when the tube 2 swings. When the wire 4 is wound up in synchronization with the sea surface waves, the tube 2 will be in the 2' position, and conversely, the wire 4 will be in the position 2'. When it is rewound, it will be at the 2'' position.The angle of inclination and submerged length of the cylinder 2 will change each time it moves up and down, and the seawater inside the cylinder will repeat large-scale vibrations.However, Since the location where the propeller turbine is located maintains a constant position regardless of this vertical movement, the distance between the generator 9 and the propeller turbine 7 can be fixed with the support rod 8. The accompanying propeller turbine 7 rotates, and the rotation is transmitted through a gear mechanism to the transmission shafts 16 and 8 shown in FIGS. 3 and 4 to the generator 9, where electricity is generated.

行なうことができるものである。 In the case of the present invention, since the mounting position of the turbine is the fulcrum of the cylinder, the position of the turbine does not change even if the cylinder moves up and down or changes its inclination angle. Therefore, the mechanism for extracting power from the turbine and transmitting it to the generator can be simplified. Furthermore, in the power transmission mechanism of the present invention, the power transmission shaft is passed through the support shaft and the power is transmitted to the generator using a gear mechanism, so power transmission is not difficult and power generation can be performed extremely efficiently. be.
