CONSTITUTION:A horizontal rotary shaft 20 at the upper edge of a longitudinal rotary shaft as output shaft is supported at the center part in the axial direction, and propeller devices 30 and 40 are arranged at the both edges of the horizontal rotary shaft 20. In other words, bevel gears 23 and 24 are fixed at the both edges of the horizontal rotary shaft 20, and the bevel gears 35 and 45 meshed with the bevel gears 23 and 24 are fixed onto the propeller shafts 32 and 42 having propellers 31 and 41 at the top edges, and the both propellers 31 and 41 are interlocking-revolved. Each propeller 31, 41 is formed into a shape which permits the efficient revolution for a head wind and does not permit the reverse revolution for a tail wind and with which the wind pressure resistance is increased. Therefore, the horizontal rotary shaft 20 is revolved by the thrust of the propeller which receives the head wind and the propeller which receives the tail wind.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a wind turbine, and mainly relates to a wind turbine for converting wind power into mechanical energy.

(Prior Art) A conventional wind turbine rotates with the rotation axis direction of the wind turbine facing the direction of the wind, as seen in Dutch wind turbines. This type of wind turbine has the disadvantage that efficiency decreases significantly when the wind direction deviates from the direction of the wind turbine's rotation axis. and,
To compensate for this drawback, a swing mechanism or the like is required to align the direction of the wind turbine's rotation axis with the direction of the wind.

In addition, in order to efficiently obtain energy even from weak wind power, this type of wind turbine generally has a large blade area that receives the wind.

However, the large area of the blades is the biggest drawback in terms of management when not in use.

This is because the larger the blade, the greater the wind pressure it will receive. Therefore, it is extremely vulnerable to weather events such as a typhoon or rainstorm. Furthermore, even in normal weather, wind turbines cannot be easily started and stopped at will; in order to operate at will, a large and complex mechanism is required. However, even if we tried to provide this, it would be impractical in terms of economic effects and other factors. The present invention was made in view of the above problems, and aims to provide a wind turbine that can efficiently obtain energy even when the wind power is small, and that minimizes the influence of wind pressure when not in use. It is.

(Structure of the Invention) The first invention has a vertically erected vertically rotating shaft as an output shaft, which is rotatable with a horizontally rotating shaft orthogonal to each other. , a propeller is provided so that thrust is exerted in the same turning direction on a turning trajectory drawn by the end of the horizontal shaft around the vertical rotation axis, and the left and right propellers are connected so that their rotation directions are the same, The rotational force of one propeller receiving a headwind rotates the other propeller receiving a tailwind, and the thrust of one propeller receiving a headwind and the other propeller receiving a tailwind rotates the vertical rotation axis via the horizontal rotation axis. The structure is such that the output is obtained by rotating the

In the second invention, a vertical rotation shaft vertically erected as an output shaft is rotatably supported with a horizontal rotation axis perpendicular to the horizontal rotation shaft, and the shaft ends of the horizontal shaft are attached to both ends of the horizontal shaft. Propellers are installed so that thrust acts in the same direction on a turning trajectory drawn around the vertical rotation axis, and the left and right propellers are connected so that their rotation directions are the same, so that one propeller receives a headwind. The rotational force of the propeller rotates the other propeller that receives a tailwind, and the thrust of one propeller that receives a headwind and the other propeller that receives a tailwind rotates the vertical rotation axis via the horizontal rotation axis to generate output. At the same time, by supporting a rotating shaft having a cup at both ends perpendicular to the horizontal rotating axis or the vertical axis, the wind receiver increases the rotational force of the horizontal axis using the wind pressure received by the cup. The structure is as follows.

In the third invention, a vertically erected vertically rotating shaft as an output shaft is rotatably supported with a horizontally rotating shaft perpendicular to the horizontally rotating shaft, and a shaft end of the horizontal shaft is provided at both ends of the horizontal shaft. The propellers are installed so that thrust acts in the same direction on the turning trajectory drawn by the vertical rotation axis, and the left and right propellers are connected so that their rotational directions are the same, and the propellers are connected so that they rotate in the same direction. The rotational force of one propeller rotates the other propeller, which receives a tailwind, and the thrust of one propeller, which receives a headwind, and the other propeller, which receives a tailwind, rotates the vertical rotation axis via the horizontal rotation axis. In addition to obtaining an output, by supporting a rotating shaft having a cup at both ends so as to be orthogonal to the horizontal rotating axis or the vertical axis, the wind receiver absorbs the rotational force of the horizontal axis using the wind pressure received by the cup. and further to the left and right sides of the center of rotation of the horizontal rotation axis.

A pair of opening/closing wings consisting of a pair of blades that close horizontally and open in the vertical direction are each attached in a direction opposite to the rotational direction of the horizontal rotation axis.When one of the opening/closing wings opens, the other closes, and when the other opens, the opening/closing wing is attached. A horizontal rotating wind turbine characterized in that one side of the wind turbine is connected in a closed relationship, and the opening/closing blades are rotated to the side receiving the tail wind and are opened by wind pressure.

(Operation) In the first invention, the rotational force of the horizontal rotating shaft is increased by the thrust of one propeller receiving a headwind and the other propeller receiving a tailwind, thereby obtaining an output.

In the second invention, the rotational force of the horizontal rotating shaft is increased by the thrust of one propeller receiving a head wind and the other propeller receiving a tail wind, and the wind pressure received by the cup of the wind receiver, and output is obtained.

The third invention is based on the thrust of one propeller receiving a head wind and the other propeller receiving a tail wind, and in addition to the wind pressure that the cup receives, the wind receiver uses the wind pressure that the opening and closing blades that turn to receive the tail wind receive. The rotational force of the horizontal rotating shaft is increased and output is obtained.

(Example) Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

In FIGS. 1 to 3, 10 is a vertical rotation shaft installed vertically as an output shaft, and 20 is a horizontal rotation shaft suspended horizontally at the upper end of the vertical rotation axis IO so as to maintain left and right balance. The moving axes 30 and 40 are propeller devices arranged on the front end side of the horizontal rotating shaft 20.

The horizontal rotation shaft 20 is rotatably supported on the vertical rotation shaft 10,
Moreover, when the horizontal rotation shaft 20 attempts to rotate about the vertical rotation axis IO, the vertical rotation shaft 10 is attached so as to rotate.

A bevel gear 23 and a bevel gear 24 are fixed to both ends of the horizontal rotation shaft 20, respectively.
is rotated together with the rotation of the horizontal rotation shaft 20.

The propeller devices 30.40 each include a propeller 31.41 and a propeller shaft 32.42, which rotate in response to a headwind.
and a base body 33.44 supporting a propeller shaft 32.42. This propeller device 30.40 is arranged so that its propeller shaft 32.42 is perpendicular to the horizontal rotation axis 20 in the horizontal plane. The propeller shaft 32.42 has a bevel gear 35.45 that meshes at right angles with the bevel gears 23 and 24 attached to both ends of the horizontal rotation shaft 20. Therefore, as shown by the arrow in Fig. 3, the propeller 3
1 and the propeller 41 are interlocked so that they rotate in the same direction. The propellers 31, 41 rotate efficiently (forward rotation) against headwinds, but are difficult to rotate backwards against tailwinds, and have a shape that increases resistance to wind pressure.

As shown in Figure 3, arrow F points to a stopped windmill.
When there is wind from the direction, one side (30) of the propeller devices 30.
) receives a tailwind. The propeller 31 on the headwind side has better wind reception efficiency and can obtain stronger rotational force (thrust) than the propeller 41 on the tailwind side.
Rotate. As a result, the propeller 41 on the tailwind side blows out wind in the opposite direction to the wind direction, and the rotating surface of the propeller 41 receives wind pressure.
The propeller device 40 side is pushed in the leeward direction, and the horizontal rotation shaft 20 begins to rotate (revolution) in the clockwise direction in the drawing around the vertical rotation shaft 10 and is activated.

The horizontal rotation shaft 20 moves along the wind direction line F as shown in the figure with the force of rotation.
-Fl, the propeller 41 that has turned to the leeward side will now receive a headwind, and the propeller 31 that has turned to the windward side will receive a tailwind. The rotational force of the propeller 41 receiving a headwind increases, and accordingly, the rotational force of the propeller 31 receiving a tailwind also increases, and the amount of wind blown toward the rear of the propeller 31 increases. Therefore, the wind pressure in the direction of propulsion of the propeller 31 is also increased. By repeating this, the horizontal rotation shaft 20 continues to rotate, and an output from the vertical rotation shaft 10 is obtained.

4 and 5 show other embodiments of an interlocking mechanism for rotating the propeller 31 and the propeller 41 in the same direction synchronously.

In FIG. 4, bevel gears 51 and 52 are mounted facing each other on both ends of the horizontal rotation shaft 20 cut off at the center.
1.52 are connected via another bevel gear 50.

FIG. 5 shows a spur gear 53 cut through the center of the horizontal rotation shaft 20.
．． 54 are attached to both ends, and these consonant gears 53 and 54 are directly meshed and connected.

In FIG. 6, one chain 55 is connected to the propeller shaft 32, and the other chain 56 is connected to the other propeller shaft 42, respectively, and the two chains 55 and 56 are connected to the shafts of a pair of spur gears 57 and 58 in mesh. Each hook is turned and connected.

FIG. 7 shows propeller shafts 32 and 42 connected to a hydraulic pump 59.
It is linked via .

In FIG. 8, the wind turbine having the above-described configuration is provided with auxiliary blades 60 in order to properly start the rotation of the wind turbine and to efficiently obtain output from the rotational force of the wind turbine and hence from the vertical rotation shaft 10. Let me explain an example.

In the figure, as an aileron blade 60, the wind receiver has a rotating shaft 63 having cups 61 and 62, which is perpendicular to the horizontal rotating shaft 20 or the vertical axis 10.

The aileron 60 of the embodiment is composed of a wooden rotation shaft 63 and wind receiving cups 61 and 62 attached to both ends thereof.

The rotation shaft 63 is rotatably supported by the horizontal rotation shaft 20 so as to be perpendicular to the horizontal rotation shaft 20 and facing in opposite directions. The horizontal rotation shaft 20 is started to rotate. Of course, after starting, the wind bridge also converts the wind force received by the cup into mechanical energy. By rotating the rotation shaft 63 by an appropriate means, the wind receiver can be placed in a first state where it is face down, where the wind pressure it receives is the minimum, and a second state where it is raised, where the wind pressure it receives is the maximum. Convert to.

By providing such a wind receiver with cups 61 and 62, when rotating the windmill, the left and right wind receivers are provided with cups 61 and 62.
．． By converting the cups 61 and 62 into the second state in which both the cups 61 and 62 are raised, the wind receiver can easily start rotation of the wind turbine with the wind pressure applied to the cups 61 and 62.

When the windmill is in a stopped state, the rotation shaft 63 is rotated to bring the left and right wind receivers into a first state with the cups 61 and 62 both facing down. This allows you to avoid wind pressure.

In FIG. 9 and FIG. 10, the illustration shows the horizontal rotation shaft 20.
Opening/closing wings 70.80 each consisting of a pair of blades that close horizontally and open in the vertical direction are attached to the left and right sides of the center of rotation, facing in a direction opposite to the rotational direction of the horizontal rotation shaft 20. Both opening/closing wings 70 This is an example of a wind turbine configured so that when one side opens, the other side closes, and when the other side opens, the other side closes, and the opening/closing blades 80 turned to the side receiving the tail wind are opened by wind pressure.

In FIG. 10, the horizontal rotation shaft 20 is divided at the center and consists of a left horizontal rotation shaft 20A and a right horizontal rotation shaft 20B whose axes are shifted parallel to the horizontal direction. The left horizontal rotation shaft 20A and the right horizontal rotation shaft 20B, which are divided into left and right parts, are connected to the left and right propeller devices 3 by a pair of spur gears 53 and 54.
0.40 propellers Jj#, i, 41 are interlocked to rotate in the same direction.

The horizontal rotation shafts 20 (20A, 20B) configured in this way
) above and below, parallel to the horizontal rotation axis 20, the main wing axis 71.
72 is arranged. On the main wing shaft 71, the main wing 70A is attached to one side lying horizontally with the vertical rotation axis 10 in the center, and the main wing 180A is attached vertically upward to the other side. ing.

On the other main wing shaft 72, a main wing 70B is attached horizontally on one side with the vertical rotation axis 10 in the center, and a main wing 80B is attached vertically downward on the other side. is attached to.

The main wings 70A and 70B located on the left side are fixed to their respective main wing axes 71 and 72 in the opposite direction to the planned rotational direction of the horizontal rotation axis 20, and are horizontally overlapped with each other as shown in the figure to maximize wind pressure. The so-called “closed state” that is difficult to accept
Hereinafter, the left pair of main 170A and main j (70B) will be referred to as the "opening/closing left wing."

On the other hand, the main wings 80A and 80B located on the right side are oriented vertically to each other in the up-and-down direction and are deployed in the so-called "open state" in which they can most easily receive wind pressure. Hereinafter, this pair of main wing 180A and main wing 80B will be referred to as an "opening/closing right wing."

In this way, the main wing 170A, the main wing 80A, and the main wing 70B
and the main yt80B are located at positions shifted by about 90 degrees with respect to the axes of the respective main wing axes 71 and 72. And Lord 31 (
The main wing shaft 71 having the main wing 70A and the main wing 31i (80A) and the main wing @72 having the main wing 70B and the main wing 80B rotate in opposite directions through spur gears 91 and 92 and spur gears 93 and 94. It is linked.

Therefore, when the currently closed left wing opens vertically in the vertical direction, the right wing that was open will close, and when the left wing fully opens vertically.

The retractable right wing is in a closed state with its main wings overlapping in parallel.

The opening and closing of the opening/closing left wing and the opening/closing right wing are automatically performed by wind pressure acting on the wings.

To explain this in Figure 11, when the open right wing is receiving a tailwind, the wind pressure acts on the open right wing in the direction of opening, and on the other left wing, the force is applied in the closing direction. Acts as a force. When the right wing is pushed by the wind and turns downwind, and the force of its rotation crosses the wind direction line F1, the open right wing, which was open, receives a headwind in the opposite direction to the direction of rotation. The headwind toward the opening and closing right wing acts as a force in the closing direction, and the opening and closing right wing is closed.

At this time, the force in the closing direction on the opening/closing right wing becomes the force in the opening direction on the other opening/closing left wing, and since the opening/closing left wing is in a state where it is hit by a tailwind beyond the wind direction line on the windward side, Opened by wind pressure. By repeating this series of cycles, the windmill rotates faster and stronger.

Note that the wind receiver cups 61 and 62 can be set in a first state where the wind pressure received is the lowest, in which they are laid down, and a second state in which they are raised, where the wind pressure they receive is maximum, by rotating the corresponding rotation shafts 63. It is expected to be converted to

Therefore, when rotating the windmill, the wind receiver is placed in the cup 61.
By providing the cup 61.62, the left and right wind receivers become the cup 61.
By converting the cups 61 and 62 into the second state in which they are both raised, the wind receiver can easily start the wind turbine by using the wind pressure applied to the cups 61 and 62.

When the windmill is stopped, the rotation shaft 63 is rotated so that the left and right wind receivers are placed in the first state with the cups 61 and 62 both facing down.
Wind pressure can be avoided.

Reference numeral 73 in the figure is a link lever for rotating the rotation shaft 63.

Next, the embodiment shown in FIGS. 12 to 15 will be described.

This embodiment is a further modification of the embodiment shown in FIG. 10, and differs from the embodiment shown in FIG. 10 in the interlocking mechanism between the left and right opening/closing wings 70 and 80.

That is, in FIG. 10, the two main wing shafts 71 and 72 connecting the left and right opening/closing wings 7o and the opening/closing wings 80 are vertically parallel,
It extends to the left and right opening/closing wings 70 and 8o, respectively.

A pair of main 5t170A forming the opening/closing blade 70,
Main j (70A and opening/closing wing 80) which is one of 70B
The main wing 80A, which is one of the pair of main wings 80A and 80B constituting the main wing 80A, is provided at both ends of one main wing shaft 71, and similarly, the other main wing 70B and the main wing 80B are provided on the other main wing shaft 72. It has a structure in which both sides are simply provided.

On the other hand, in the embodiment shown in FIGS. 12 to 15, the main wing axes 71 and 72 are connected to the left and right opening and closing wings 70 and the opening and closing wings 80.
In order to rotate the rotation directions of the main wing shafts 71 and 72 in opposite directions, there is a meshing mesh provided at a distance near the center of the main wing shafts 71 and 72. The respective main wing shafts 71.72 between the spur gears 91.92 and 93.94 are separated.

What are the left and right sides of the divided main wing shafts 71 and 72, that is, the right opening/closing wing 70 side and the left opening/closing wing 80 side?

The respective main wing axes 71 and 72 remain vertically parallel, but
The left and right axes are staggered and are arranged in parallel in a horizontal position.

Then, the shaft 72A on the right side (right opening/closing R70 side) of the main wing shafts 72 arranged in a staggered manner and the 728 axis on the left side (left opening/closing wing 8
The left and right main shafts are connected to the 0) side via a link mechanism 95 so that they rotate in the same direction.

FIG. 14 shows the structure of the link mechanism 95.
Not limited to this structure, the linked left and right main wing shafts 72
The link mechanism 95, which only needs to be connected so that A and 72B rotate in the same direction, operates as shown by solid lines and broken lines in the figure.

Note that the other structures are substantially the same as the structure shown in FIG. 1O above, so the same symbols are given.

(Effects of the Invention) The wind turbine of the present invention can always receive the wind pressure regardless of the wind direction. The windmill will not drop or the windmill will stop rotating.

Therefore, wind energy can always be extracted as mechanical energy without requiring a swinging mechanism or the like to align the direction of the wind turbine's rotation axis with the direction of the wind.

In addition, in conventional wind turbines, the area of the blades that receive the wind is generally large in order to efficiently obtain energy even from weak wind power, but the present invention uses a propeller, so even if the wind power is small, the area of the blade is large. Energy can be obtained efficiently and the influence of wind pressure when not in use can be minimized.
