JPH08100756A - Drag difference rotor by horizontal and vertical blades - Google Patents

Abstract

PURPOSE: To increase conversion efficiency of a drag difference rotor which changes force of linear and parallel stream into rotary force. CONSTITUTION: A vertical rotary shaft O is provided at a center and an arm shaft 3 passes through it in the shape of character T. Same blades l, 2 are fixed respectively horizontally and vertically at symmetrical positions on the right and left of the arm shaft 3. The arm shaft 3 rotates horizontally together with the rotary shaft O and rotates vertically down to a stopper 4. Consequently, if one blade 2 is vertical, the other blade 1 becomes horizontal without fail. The blades which are horizontal and vertical for streams generate drag difference and convert the movement of parallel streams into rotating movement based on the vertical rotary shaft.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drag difference rotating body such as a wind turbine or a water turbine that rotates due to a drag difference.

[0002]

2. Description of the Related Art Conventionally, as a rotating body due to a resistance difference, there are a cup-shaped windmill seen in a wind force measuring instrument, a Z-shaped store-front rotating signboard, and ai, a saponius-type windmill, and an autogyro rotor. .

[0003]

However, all of them have a small blade area difference when viewed from the flow direction, and therefore have a small difference in drag force between the left and right sides, so that the rotational force of the hydrodynamic force is smaller than that of other wind turbines. Conversion efficiency is low. Therefore, it was never considered as an early windmill.

In particular, the resistance on the side where the blade runs counter to the flow direction is large, and ideally, it is desired to make this zero to increase the drag difference. Therefore, how to approach this to zero is an issue for increasing the conversion efficiency of this type of drag difference rotating body.

[0005]

[Means for Solving the Problems]

In the horizontally flowing fluid, the resistance is minimum when the plate is placed horizontally along the flow and maximum when it is placed vertically. That is, in this state, the drag difference becomes maximum.

According to the present invention, the blades (1) and (2) are fixed in a horizontal and vertical state and half-rotated by a hinge mechanism. When (1) is horizontal, (2) is vertical, and when (2) is horizontal ( 1) is a structure that ensures vertical, and is a means for maximizing the drag difference and increasing the conversion efficiency.

[0008]

[Work]

Describing this operation with reference to the drawings, since the blades (1) and (2) are fixed horizontally and vertically to the arm shaft (3), when the blade (2) is in the flow from the direction of arrow A, ) Is pushed by the flow and rotates vertically to the stopper (4) and becomes perpendicular to the flow. At that time, (1) becomes horizontal. State (a) in Figure 2

When the horizontal rotation advances about the vertical rotation axis O and the arm axis (3) passes parallel to the flow direction, the stopper (4) is in a position where it does not act. Therefore, the blade (2) is ready for free rotation.

Explaining with reference to FIG. 2B, the blade (2) rotates in the direction of arrow C, moving from the dotted line state to the hydraulic force,
Level. There the blade (1) automatically ensures that it is vertical.

By repeating the above, the parallel fluid force from the arrow A direction can be converted into the rotational force in the arrow B direction.

【Example】

In practice, the entire housing (6)
Can be incorporated into. Then, as shown in FIG. 3, the housing can be a duct mechanism to collect the flow in the same direction as the rotation of the arm shaft (3).

Combination with other wind turbines is possible.
Especially in combination with Darius wind turbine and gyro mill wind turbine, see below.

There are the following effects.

In practice, the blades are placed in symmetrical positions,
It can be four.

[0017]

[Invention effect]

Since the present invention is constructed as described above, it has the following effects.

Since the resistance on the side opposite to the flow is close to zero, the drag difference is larger than that of the conventional one, and the conversion efficiency of the fluid force into the rotational force is high.

The combined use of the Darrieus wind turbine and the gyro mill wind turbine facilitates the initial start-up, which is a drawback thereof, and eliminates the need for a mechanism and a power supply therefor.

Application to a water turbine, which is clean, safe, and has excellent natural energy, greatly expands its location conditions.

That is, it is suitable for pumping up the energy of rivers in the plain, which has not been used because it has a small head as before, but has abundant water but has a shallow water bottom.

Further, even if the flow is a reverse flow like in a Wells turbine, it rotates in the same direction.

Further, the wind from all directions can be used as the wind turbine, and when it is used for a yacht, if the rotation is interlocked with the screw, the wind can proceed toward the wind.
