Description

本発明は海流発電用三胴船、特に台風や強風域での風のエネルギーを電気に変換するに適
した海流発電用三胴船に関する。 TECHNICAL FIELD The present invention relates to a trimaran for ocean current power generation, and more particularly to a trimaran for ocean current power generation suitable for converting wind energy in typhoons and strong wind regions into electricity.

台風等の強い風を硬翼帆で受けて帆走する船の航行によって生じる海流で船体の下に設け
たプロペラを回転させ発電機で電気を起こす発電船はすでに提案されている。 A power-generating ship has already been proposed in which a propeller installed under the hull is rotated by a current generated by a ship sailing against strong winds such as typhoons with hard sails to generate electricity with a generator.

ている場合はプロペラの回転効率が悪くなり発電効率が低下する等の欠点を有している。 The power generation ship described in the prior art JP 2014-184935 A has a structure in which a propeller protrudes under a single hull and is rotated by ocean currents. For this reason, (1) a tall ship with hard sails is subject to strong rolling due to the force of the wind. (2) When a propeller rotates without an obstacle such as an enclosure around it, a vortex is generated at the tip of the propeller perpendicular to the direction of travel of the ship, absorbing the energy of the ocean current, resulting in poor power generation efficiency. (3) When transverse waves are flowing, the propeller rotation efficiency is deteriorated, resulting in a decrease in power generation efficiency.

本発明は、発電船を三胴船構造にし、発電用のプロペラに円筒状の覆い（以下円筒形ダク

カットすることが好ましい。 It is an object of the present invention to eliminate the above drawbacks by making the power-generating ship a trimaran structure and covering the power-generating propeller with a cylindrical cover (hereinafter referred to as a cylindrical duct).
That is, the present invention provides a trimaran sailing with hard sails by providing a pair of side floats on the left and right sides of a main hull having a tapered bow, and a pair of side floats under the draft between the main hull and the left and right side floats. (1) is provided with a long cylindrical duct, and a propeller for power generation that is rotated by the ocean current is provided in the cylindrical duct.
In order to reduce water resistance, it is preferable that the tip of the side float is cut obliquely toward the inside.

この発電機ユニットは、長尺の円筒形ダクトの先端に設ける以外に、必要に応じて両端、
さらには中間に設けてもよい。 In addition, the cylindrical duct separation part, which is separated from the cylindrical duct body with the propeller for power generation that rotates due to ocean currents, and the generator that generates power by rotating the propeller for power generation, are integrated into an independent container. The generator unit was constructed by accommodating it in
Although the size of the cylindrical duct varies depending on the size of the main hull, it is preferable that the length be in the range of 10 to 200m and the diameter be in the range of 3 to 20m.
In addition to installing this generator unit at the tip of the long cylindrical duct,
Furthermore, you may provide in the middle.

そして、発電機ユニットを吃水上の船体内に設けられた発電機ユニット収納室に移動させ

向上する等の利点がある。 In addition to a single propeller, a contra-rotating propeller can be used as the propeller for power generation in order to further increase the efficiency. Contra-rotating propellers are two sets of propellers that are coaxially arranged and driven in opposite directions to each other.
There is an advantage that the efficiency is improved by canceling out the energy that would be lost as the twist of the flow in one set.

The honeycomb structure is formed by alternately stacking flat plates impregnated with epoxy resin with carbon fiber reinforced orthogonal fabrics and honeycomb layers to form 5 to 9 layers with a thickness of about 5 cm.

、効率よく海流のエネルギーをプロペラの回転に変換でき発電効率を高める。 A pair of long cylindrical ducts are installed under the draft between the main hull with a tapered bow and the left and right side floats, and a propeller for power generation that rotates due to the ocean current is installed in the cylindrical ducts. A triangular sea area is formed between the tapered bow of the hull and the tip of the side float, and the ocean current flows into it. You can increase the power generation efficiency by increasing the rotation speed. In addition, even in the case of transverse waves, the side floats stop the transverse waves, rectify the ocean currents in the direction of travel of the ship in the triangular sea area, and suppress the effect of reducing the momentum of the ocean currents flowing into the cylindrical duct due to the transverse waves. .
Furthermore, the trumpet effect can be promoted by cutting the tip of the side float obliquely toward the inside.
In addition, the cylindrical duct rectifies the ocean current and suppresses the generation of eddy currents generated from the tip of the propeller, so the energy of the ocean current can be efficiently converted into the rotation of the propeller, increasing the power generation efficiency.

Since we have provided a means to move it inside the ship on the water, during the power generation stop,
The generator unit can be retracted into the generator unit storage room to reduce water resistance. In addition, maintenance of the generator unit can be carried out onboard on the draft.

前記発電用プロペラとしては単独のプロペラ以外にさらに効率を上げるために二重反転プ
ロペラを使用することにより、発電効率を上げることができる。 Power generation efficiency can be increased by using a contra-rotating propeller as the propeller for power generation in order to further increase efficiency in addition to a single propeller.

しかも堅牢で帆の伸縮操作を容易にし、長期使用にも耐えうる効果を有する。 A foldable hard sail was used as the hard sail, so the sail area can be changed according to the strength of the wind. In addition, when operating independently in no wind, wind resistance can be eliminated by completely folding the sails. In addition, the use of a zigzag hard sail makes it possible to extend and retract the sail with a simple structure, and the carbon fiber honeycomb structure of the hard sail makes it lightweight and robust, making it easy to extend and retract the sail. It has an effect that can withstand use.

させる。 FIG. 14 is an explanatory diagram showing the course of a typhoon, the course of the ocean current power generation trimaran of the present invention, and the angles of the hard sails.
Typhoon R1 (R2 is the eye of the typhoon) rotates clockwise and the wind force gradually increases. Therefore, when the force of the typhoon is strong in S1, the trimaran for power generation T1 is positioned behind and to the left of the typhoon, and the angle of the hard sail is directed in the direction of 5 o'clock to 11 o'clock, which is the same as the course direction P of the typhoon. It sails in direction Q and generates ocean current power. If the wind is a little strong, at S2, place the trimaran at T2, turn the angle of the hard sails in the direction of 4 o'clock to 10 o'clock, and sail in the direction of the typhoon's course Q to generate power from the ocean current. . For slightly less wind S3, position the trimaran at T3 with the hard sail angled in the direction of 3 o'clock to 9 o'clock.
Approximately 50 to 1,000 such trimarans are lined up and sailed to absorb the force of the typhoon and generate electricity while weakening the force of the typhoon.
When the power generation of the typhoon is stopped, the self-propulsion screw 8 is used to move to the home port or the place where the tidal current power generation is performed, and the power generation is performed in the moored state. In the case of self-propulsion, the generator unit 6 is lifted into the generator unit storage room 25 to reduce the resistance of the ocean current caused by the generator unit 6 .
