Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid energy conversion device for converting fluid energy into mechanical energy when installed in a fluid, particularly water.

[0002]

2. Description of the Related Art In recent years, photovoltaic power generation and wind power generation have come into practical use due to concerns about depletion of petroleum energy, environmental destruction, and safety.

[0003]

However, photovoltaic power generation has a problem that it does not function in rainy weather, cloudy weather, and at night, and wind power generation is not only easily affected by wind speed but also wind energy. There is a problem that the power generation capacity per unit is limited due to its small size. Therefore, the present inventor has conducted intensive research on an energy conversion device that uses natural energy and has a large power generation capacity per unit, and as a result, has found the fact that it is only necessary to use the flow of water in the sea or river, and has made the present invention. completed. Therefore, an object of the present invention is to provide a device that can efficiently convert fluid energy of the sea or river into mechanical energy and finally extract it as electric energy.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a rotary spindle whose both ends are pivotally supported, a plurality of columns radially implanted with respect to the rotary spindle, and The supporting shaft is composed of a rotating shaft suspended in parallel with the rotating main shaft and blades asymmetrically supported on each of the rotating shafts with respect to the center of rotation. When receiving the energy of the fluid flowing in the direction, the apparatus converts the fluid energy as a rotational force with respect to the rotating main shaft.

[0005]

Next, an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, in a fluid energy conversion device 1 according to the present invention, one rotating spindle 2 is provided at both ends 2a with respect to a bearing (not shown) of a main body frame installed in the sea or a river. , 2b, and a plurality of, preferably four or more pairs of columns 3 are radially implanted in parallel with the main spindle 2 at a predetermined interval.

[0006] Further, between the pair of columns 3a and 3b constituting each column 3, the rotating main shaft 2 is located near the tip.
The rotating shafts 4 are suspended in parallel with the rotating shafts 4, and the rectangular blades 5, which are slightly narrower than the interval L between the columns 3 a and 3 b, are asymmetrical with respect to the rotating center d of the rotating shafts 4. , I.e., near the tip. One or a plurality of rod-shaped rotation stoppers 6 longer than the interval L are attached to one side of the blade 5, and the base end 5 b side of the blade 5 is centered on the tip 5 a by an arrow X. , But more than a predetermined angle, preferably
It does not rotate more than an angle parallel to.
Therefore, it can be said that the device according to the present invention is a kind of water turbine.

[0007] The fluid energy conversion device 1 configured as described above is attached to the main body frame, and a location where water flows in one direction Y, such as a strait where a tidal current always flows in one direction, When the main shaft 2 is submerged in the river so that the main spindle 2 is perpendicular to the flow of the water in the direction Y, each blade 5 rotates under the water pressure. The rotation of the blade 5 is limited to a predetermined range because the blade 5 is asymmetrically supported with respect to d and the rotation stopper 6 is attached to each blade 5.

That is, in the embodiment shown in FIG. 1, when an arbitrary support is focused on and the support 3 is at the vertical position A on the rotary main shaft 2, the blade 5 between the support 3a and 3b is It stops at the rotational position where it becomes parallel, and does not rotate further in the direction of arrow X. for that reason,
The blade 5 receives the fluid energy of water almost as it is,
The rotary main shaft 2 is rotated via the support 3 in the direction of the mark Z.

On the other hand, when the column 3 noted above rotates and comes to the vertical position B below the rotating main shaft 2, the blade 5 rotates around the rotating shaft 4 in the direction opposite to the direction of the arrow X. It moves and hangs on the rotating shaft 4. Therefore, a pair of columns 3
The blade 5 substantially disappears between a and 3b, and the tip 5a of the suspended blade 5 becomes a free end. Therefore, even if the water flow in the direction of arrow Y collides with the blade 5 at the position B, almost no force is generated for rotating the rotary spindle 2 in the direction opposite to the direction of arrow X.

Further, when the support 3 comes to the intermediate position C in the process of rotating from the vertical position A to the vertical position B, the blades 5 face the same direction as the direction of the water flow.
Fluid energy cannot be converted into energy for rotating the rotating main shaft 2. Similarly, when the support 3 comes to the intermediate position D in the process of rotating from the vertical position B to the vertical position A, the blade 5 is suspended from the rotating shaft 4,
Cannot be converted into the rotational energy of the rotating main shaft 2 as in the case where is in the vertical position B.

As described above, during the process in which the column 3 rotates from the intermediate position D to the intermediate position B via the vertical position A, the apparatus according to the present invention converts the fluid energy into the rotational energy of the rotary main shaft 2. You can do it. Therefore, if the rotation of the rotating main shaft 2 is transmitted to the generator (both not shown) via the pulley 7 and its transmission means 8 or gears, the fluid energy can be eventually extracted as electric energy. Since underwater fluid energy is strong and inexhaustible in some places, if the device according to the present invention is installed in such a place and a generator is attached to it, a large amount of electric energy is always obtained from nature for each of the generators. It becomes possible.

The present invention can be carried out by partially modifying the above-described embodiments to the extent that the effects of the invention are not significantly impaired by following the fundamental technical concept thereof. For example, the number of columns 3 can be increased, and a pair of columns 3a, 3b is provided with a pivot 4 at a position closer to the distal end or the proximal end from their central position in the radial direction, Similarly, the blades 5 can be axially supported on the rotating shaft 4 asymmetrically in the longitudinal direction to convert the fluid energy into the rotational energy of the rotating main shaft 2.

Further, if the rotation stopper 6 can also be formed integrally with the blade 5, or if the rotation shaft 4 can rotate the blade 5 to rotate in one direction within a predetermined rotation range. It can be changed to any shape and structure. The support 3 also has a pair of supports 3a as long as the blades 5 can be rotatably mounted on the way.
Instead of 3b, one support can be used.

[0014]

As described in detail above, the present invention has an excellent effect that the fluid energy of the sea or river can be efficiently converted into mechanical energy and eventually into electric energy.
