Abstract

PURPOSE:To enable a sail boat to sail against wind coming to the front by supporting swingably the fornt edge of vertical vane turning around the vertical shaft, and connecting the rear edge vicinity to the eccentric vertical shaft to turn freely, and making the eccentric direction be in conformity with the downstream direction by the wind acting on the vertical shaft. CONSTITUTION:When wind strikes a vertical vane 9 a rear edge 25 moves downstream or in the front direction due to wind pressure, but an upward shaft 20 fitted in a coupled large end part 22 by rods 21, 26 is opposed in its direction to a lever 16 and a fixed arm 12, and moves to the position offset from the center of a vertical shaft to the downstream direction only by the difference in length from the center. With the wind from the front of a boat body 1 the direction of shaft 20 is made the same as the fixed arm 12 and the bar 16, and the eccentric amount from the vertical shaft 2 is the total of the distances between the arm shaft 14 and the vertical shaft 2 and between the arm 14 and the upward shaft 20 to have a large value. The moving angle of the rear edge of the vane 9 inclining downstream becomes large and thus the turning force of the vane 9 becomes large.

【産業上の利用分野】本発明は風車を利用して走る帆船
に関するものであり、特に正面から吹く風でも前進する
ことの出来る帆船に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sailing vessel that uses a wind turbine, and more particularly to a sailing vessel that can move forward even with wind blowing from the front.

【発明が解決しようとする課題】上記のごとき帆船は、
主として次の３つの問題がある。これを解決するのが本
発明の課題である。以下その内容を具体的に述べる。[Problems to be Solved by the Invention]
There are three main problems. It is an object of the present invention to solve this. The contents will be specifically described below.

【０００４】第１の問題として、いわゆるヨットについ
ては正面からの風では前に進む事が出来ない為に、ジグ
ザグにタッキングを繰り返しながら進まなくてはなら
ず、操縦が難しい事である。The first problem is that a so-called yacht cannot be moved forward by the wind from the front, so it is necessary to repeatedly tackle in a zigzag manner, and it is difficult to control the yacht.

【０００５】又、第２の問題はプロペラ型風車を利用し
たものでは、風の向きによりプロペラの方向を制御し
又、風による抵抗が少なく、回転力が大きくなるように
プロペラのピッチを変化させるなどの制御が必要であり
構造が複雑なだけでなく操縦も難しい。The second problem is that in the case of using a propeller type wind turbine, the propeller direction is controlled by the direction of the wind, and the propeller pitch is changed so that the resistance due to the wind is small and the rotational force is large. Not only is the structure complicated, but it is also difficult to control.

為には、推進プロペラのピッチを変えたり又、駆動部に
変速機を設けこれを微妙に制御しなくてはならないもの
であり構造も複雑で操縦も非常に難しい。A third problem is that the vertical axis type wind turbine called Darrieus type which does not change in pitch has a characteristic that the relation between the wind speed and the rotational speed is delicate, and if this relation is broken, the efficiency is improved. However, not only can we not proceed with the wind from the front, but also the sail speed will decrease even in the cross wind. In order to compensate for this, it is necessary to change the pitch of the propulsion propeller, and to provide a derailleur in the drive unit to delicately control it, which is complicated in structure and extremely difficult to control.

【００１１】[0011]

【作用】下記に本発明の帆船の作用を説明する。The operation of the sailboat of the present invention will be described below.

の後縁が風下に傾く角度は中央の偏芯鉛直軸の偏芯量に
応じた角度となる。When wind strikes a vertical blade whose front edge is swingably supported, the wind pressure causes the trailing edge to lean to the leeward side. Then, the wind flows along the blade surface from the leading edge to the trailing edge, and the recoil causes the vertical blade to rotate around the central vertical axis toward the leading edge. The rotational force is transmitted to the underwater propeller through the rotation transmission mechanism to rotate the propeller. The angle at which the trailing edge of the vertical blade tilts to the leeward side is an angle according to the amount of eccentricity of the central eccentric vertical axis.

【００１３】一般に後からの風のときは鉛直翼に生じる
風の抵抗力が船の前進を助けるので、プロペラは小さな
トルクで軽く回すことができるので、前記後縁の風下へ
の傾き角度は小さくてよい。Generally, in the case of wind from the rear, the resistance force of the wind generated on the vertical blades assists the forward movement of the ship, so that the propeller can be turned lightly with a small torque, so the inclination angle of the trailing edge to the leeward is small. You may

ならない。横風に対してはこの中間である。On the contrary, when the wind is applied from the front, the torque required to rotate the propeller is larger than that in the above-mentioned state because the wind is moved against the drag acting on the vertical blades. The tilt angle of must be increased. It is in the middle for cross winds.

FIG. 3 is a partial top view showing a state when the sailboat of the present invention receives wind from the rear. In FIG. 3, when the wind W hits the vertical blades 9, the trailing edge portion 25 moves downward by the wind pressure, that is, moves to the bow side, but the large end portion 22 connected by the rod 21 and the small rod 26 has the upward shaft 20. Since the direction of the bar 16 and the fixed arm 12 of the upward shaft 20 is reversed, the position is eccentric to the leeward side from the center of the vertical shaft 2 by the difference in length from the center. Move to. This amount of eccentricity is relatively small, and therefore the movement angle α1 at which the trailing edge of the vertical blade 9 tilts to the leeward side is small. In this state, the rotating speed of the vertical blades 9 is high and the rotating force is small with respect to the wind speed W.

良く進む事ができる。On the other hand, when the wind from the rear is received, the hull 1 moves forward due to its resistance, so that the relative speed between the wind and the vertical blades 9 becomes smaller according to the speed, but the propeller 37 moves to the speed of the hull 1 in water. Accordingly, the vertical blades 9 rotate at a high speed even in a relatively weak wind, which is a convenient state because of the necessity to rotate the vertical blades accordingly. Moreover, in this state, since the hull originally moves forward due to wind resistance, the force that the propeller 37 bears to move forward is small. Therefore, the rotational force of the propeller 37 can be small, which is very convenient and proceeds efficiently. I can do things.

直翼９の回転速度は小さく、回転力は大きい。FIG. 4 is a partial top view showing a state where the hull 1 receives wind from the front. In FIG. 4, since the shaft 20 has the fixed arm 12 and the bar 16 oriented in the same direction, the amount of eccentricity from the vertical shaft 2 is the distance between the vertical shaft 2 and the rotary arm shaft 14 and the rotary arm. -The sum of the shaft 14 and the upward shaft 20,
It will be a large value. Therefore, the movement angle α2 at which the trailing edge of the vertical blade 9 tilts to the leeward side is large. In this state, the rotation speed of the vertical blades 9 is small and the rotation force is large with respect to the wind speed W.

が出来る。On the other hand, when the wind from the front is received, the hull 1 tries to move backward due to the resistance, so that the propeller 37 rotating in water must have a strong rotational force in order to move forward against this. Further, when the hull 1 advances, the relative speed between the wind and the vertical blades 9 increases in accordance with the speed, so that although the α2 is large as a result, the rotation of the propeller 37 is correspondingly increased, and the above-mentioned FIG. You can proceed efficiently with the relationship shown in.

度は改良により増加しつつある。FIG. 5 is a partial top view showing a state of sailing by receiving wind from the side surface of the hull 1. In FIG. 5, the fixed arm 12 and the bar 16 are close to each other at a right angle, and the combined eccentricity is in the middle of FIGS. 3 and 4. Therefore, the movement angle α3 also becomes an intermediate value between FIG. 3 and FIG. It is the same as in the case of a yacht that this state is the easiest to sail. By the way, if the wind speed is 10 m / s, if this is a tail wind, the sailing speed is about 7.5 m / s, and if the head wind is 6 m,
If it is a crosswind, it will be 12-14 m. However, the speed at headwind is increasing due to improvement.

ていることが出来る。FIG. 6 is a partial top view showing a stopped state. In FIG. 6, the wire 28 is pulled in and the hook 3
Hook the wheel 35 on 4. In this state, the sliding block 17 has moved to the tip of the bar 16, so that the trailing edge of the vertical blade 9 is completely directed to the leeward side, and the movement angle α4 becomes maximum. Especially, since one of the vertical blades 9 originally has a leading edge on the leeward side, α4 is close to 120 °.
This is possible by bending the joint portion 23 on the rod 21 and the small rod 26. In this state, the vertical blades 9 do not rotate even if the wind blows, and since the wind and the blade surface are parallel to each other, the wind resistance is small and the ship can be stopped in a safe state.

The sliding block 17 moves in the direction of the rotary arm shaft 14 by the force of. Then, since the rod 21 pulls the joint 23, the vertical wing 9 rotates about the axis 11, and when the joint 23 extends straight by the force of the spring 24, the vertical wing 9 rotates around the vertical axis 2 by the force of the wind. It will be able to rotate to the normal sailing state very easily.

Since the angle of attack is reduced, it is possible to avoid this excessive wind force and sail safely without breaking or overturning the mast unlike conventional yachts.

しい。As is clear from the above description, the vertical axis wind turbine type sailing ship of the present invention enables sailing in the wind from the front, which has been practically impossible up to now, so that it is zigzag like a yacht. Since it is not necessary to proceed while tacking, it is very easy to operate, and there is no need to change the angle and pitch of the propeller according to the wind direction unlike the one using a propeller type wind turbine. Further, there is no difficulty that the pitch of the propeller in the water, the transmission, etc. have to be delicately controlled according to the wind speed unlike the one using the Darrieus type wind turbine. Moreover, it is highly safe without damage or overturning due to gusts. Furthermore, since the structure is simple, it can be manufactured at low cost, and the range of applications such as leisure ships, fishing boats, and transport ships is greatly expanded, and its industrial effect is extremely remarkable.
