Abstract

PURPOSE:To enable to obtain the stable turning power from wind unstable in its force by a method wherein blades are moved temporarily in the same direction as the wind so as to obtain turning moment. CONSTITUTION:When wind strikes against the blades 3 and 4, the pairs of the blades located in a semicircular demain B irrespect to the direction of wind A bring the blades 3 and 4 into an open state, while those located in the other semicircular demain C bring the blades 3 and 4 into a closed state. Consequently, the pairs in the semicircular demain B are applied by wind pressure and at the same time the pairs in tbe semicircular demain C dodges wind pressure by closing blades in the direction opposite to the direction of wind A, resulting in causing arms to swirl and turning a strut 1. The rotation results from the difference between the wind pressure strinking against the pairs of the blades in the open state and the wind pressure applied onto the pairs of the blades in the closed state and yet the magnitude of the turning force is large, because the blades in the open state move in the same direction as the direction of wind.

Description

[Detailed Description of the Invention] This invention relates to a wind-powered rotary machine that obtains rotational power from the force of the wind, and is intended to obtain relatively stable rotational power from wind whose strength is unstable. .

Generally, the blades of a windmill receive wind on an inclined surface, and the blades rotate in a direction perpendicular to the direction of the received wind.In the present invention, the blades are temporarily moved in the same direction as the wind to obtain a large rotational torque. This is also a feature of the present invention.

The present invention will be described in detail based on the drawings. A number of arms 2 are horizontally protruded from a support column 1, which is rotatably supported, and are equally spaced around the periphery, and upper and lower wings 3.4 are hinged to each arm 2. The wings 3 and 4 can be bent in one direction when the arm turns due to their hinge structure, and are provided with stoppers to prevent bending in the other direction. Further, the pillar 1 and the arm 2 are hollow, and a weight 5 is slidably stored in each arm 2, and a weight 6 is slidably stored in the pillar 1, and each weight 5 is connected to the weight 6 by a lobe 7. It is.

Note that 8/'i is a spring provided so that the upper and lower wings 3, 4 return to the half-open position in a natural state. 9 protrudes a pulley that transmits the rotation generated in the support 1 to the other parts, and a heavy @
When the weight 6 rises, the weight 6 causes the weight 6 to retreat outward once, and then protrudes inward again to engage the suppression portion 12 of the weight 6 to prevent the subsequent upper row of the weight 6. is provided, and the restraining device 13 is configured to retreat outward and detach from the restraining portion 12 when the support column 1 stops rotating.

Next, the operating state of the wind rotating machine with and σ will be explained. When wind hits R3 and R4 from one direction, the blades open up and down in the semicircular part B relative to the wind direction A, and close in the other semicircular part C. Therefore, in the semicircular part BC, 1 flows under the wind pressure, and in the semicircular part C, it closes to cut off the wind and return to its original state, and the arm can be easily set to be larger by 1 minute by turning. The open wings flow with the wind, creating a large amount of rotational force.

When the rotational speed increases, the weight 5 moves outward due to centrifugal force, pulls up the weight 6, and the restraining device 13 engages with the restraining portion 12 to prevent the M@6 from descending.

That is, since the weights 5 are in the outward direction, even if the moment of inertia increases and the wind force becomes uneven, smooth rotation can be maintained without sudden changes in the rotational speed. When the rotation is completely stopped, the restraining device] 3 is removed, the weight 6 is lowered, and the eight 55 is pulled back inward, so that the next time it is exposed to the wind, the resistance becomes small and the rotation is easily started.

In this way, there is an effect of reducing changes in rotation compared to changes in wind power.

As mentioned above, if the present invention is implemented, it will be relatively strong and durable.
It has the advantage of being able to achieve continuous rotation due to the wind.
