2. Description of the Related Art Conventionally, natural energy has been used in industry by: 1) constructing a dam using hydropower to increase the energy density and then generating electricity. 2 Power supply such as power generation or irrigation pumps using huge water turbines and flow passages using hydropower. 3. Water will be taken from a water source with a difference in elevation by pipes and used as a power source for power generation or irrigation pumps. 4. Build huge propellers and props by wind power and use them as power sources for power generation or irrigation pumps in places with relatively high energy density. As described above, the power generation facilities were huge and expensive, and the geographical factors that could be built were limited. In addition, kinetic energy with low energy density, such as natural breeze and general river water flow, was hardly used because it was not economically viable with equipment costs. Recently, small sets that can be installed by individuals, such as wind power generation, have become widespread. However, the cost of equipment is high for practical use of energy, and the installation location is limited, making it impractical.

The problem to be solved is to reduce the installation and manufacturing costs of equipment and equipment for converting natural low density kinetic energy into kinetic energy which can be used in industry. Reduces manufacturing costs by reducing structure simplicity and weight, and reduces energy required for manufacturing. 2 It has a foldable structure so that it is not bulky during transportation and installation.
Reduce time and geographical constraints. (3) The installation and support structure of the rotating body is simplified, so that the cost, time, and geographical restrictions required for transport installation are reduced, and the manufacturing cost is also reduced. It is to solve the above problems.

SUMMARY OF THE INVENTION In order to recover more kinetic energy, the present invention has a large effective area of a passive body which receives a fluid flow, and a rotary body is manufactured at low cost. In order to make the structure compact,

As shown in FIGS. 1, 3, 4, 5, 6, 7, 8, and 9, the rotating bodies 2, 13, 16, 20, and 24, which are main structures, are airtight. Gas and liquid or a mixture of them in a gaseous or liquid state or a mixture of gaseous and liquid structures. After filling, the original functional shape can be formed, so that the amount of material used is minimized and the manufacturing cost can be reduced, and the effect can be exerted especially in large-scale and mass production. 2. The gas and liquid to be injected inside can be easily procured and injected at the installation site.
Cost and labor can be reduced. 3 The specific gravity of the rotating bodies 2, 13, 16, 20, 24 can be adjusted by selecting the specific gravity of the gas or liquid to be injected into the interior, or the ratio thereof. In addition, it is also possible to float in the air by injecting a lighter gas such as hydrogen or helium in the air. 4 When converting weak wind into rotational motion, the inertial weight of the rotating body becomes a problem, but by reducing the filling, the rotating body 2,
The inertial weights of 13, 16, 20, and 24 can be reduced. 5. The rigidity required for the rotating bodies 2, 13, 16, 20, 24 is the drag of the fluid flow and the stress due to its own weight, which is mainly transmitted as the tensile stress of the membrane by the internal filling pressure. By increasing the filling pressure by using a composite material such as a steel belt or glass fiber, it is possible to increase the weight ratio strength and rigidity. To disperse the stress, appropriately use wires, ribs, bone structure by pneumatic molding, etc. Reinforcement is also possible. 6 Change the shape of the rotating bodies 2,13,16,20,24 to CA
By forming a film using a computer technology such as D, CAM, CEA, or three-dimensional molding, it is possible to calculate and design a shape in accordance with film stress and fluid dynamics. 7 By adjusting the pressure of the filling fluid of the rotating bodies 2, 13, 16, 20, and 24, it is possible to prevent an overload that exceeds the membrane strength from occurring. Can be dealt with by pulling out the and reducing the apparent volume. Also, the filling pressure can be automatically controlled.

As shown in FIG. 1, FIG. 6, FIG. 7, FIG. 8, and FIG.
By arranging a plurality of buckets 1 and 21a in a bucket shape with the rotation direction and the bucket opening aligned with the circumference of the rotator, the membrane is pushed out in the flow that is going to flow into the opening, and the bucket membranes 3 and 21 It becomes a bucket shape and has a large flow resistance. When flowing out from the opposite side, the bucket membrane 3a,
21a is pushed back and crushed into the shape of the rotating bodies 2, 20, and 24, and the flow resistance is reduced. When the difference in the resistance of the flow coincides with the rotation direction of the rotating bodies 2, 20, and 24, torque is generated in the rotating bodies 2, 20, and 24. 1 With a simple membrane structure, the rotating bodies 2, 20, and 24 24 can be easily manufactured and the cost is low. 2 Even when the fluid velocity is low, a large resistance difference can be created. (3) An axial rotation force perpendicular to the flow of the fluid can be generated, and the casing is unnecessary and the structure is simplified. 6 Change the bucket shape and material required performance
By using computer technology such as CEA and three-dimensional molding, reinforcement can be appropriately made with wires, ribs, bone structure by pneumatic membrane molding, etc., and it is possible to calculate and design the shape according to membrane stress and fluid dynamics of the wing.

As shown in FIG. 3, FIG. 4 and FIG. 5, the wings are arranged on the rotating body circumference as spiral wings 14 having a helical structure or rotating wings 15 and 17 having a propeller wing shape. Due to the flow of the fluid, the spiral structure or the propeller blade shape generates a drag on the rotating body in a direction perpendicular to the rotation axis, and generates torque on the rotating bodies 13 and 16. By using a film structure or a film structure or a combination of a film structure and a film structure, a rotating body can be easily fabricated and the cost is low. 2 Rotational speed, depending on helical pitch and propeller blade inclination angle
The torque can be adjusted. (3) A shaft rotating force parallel to the flow of the fluid can be generated, and the casing is unnecessary and the structure is simplified. 4 High-speed rotation is possible because the wing shape itself does not deform. 5 Regarding the wing cross-sectional shape, wing length and spiral wing shape, CA
By using computer technology such as D, CAM, CEA, and three-dimensional molding, reinforcement with wires, ribs, bone structures by pneumatic membrane molding, etc. is possible, and calculation and design of shapes in accordance with wing stress and fluid dynamics. Can be. 6 Adjusting the pressure of the filling fluid in the rotating bodies 13 and 16 prevents overloading exceeding the membrane strength, and at abnormally high operating flow rates, removes the filling pressure for safety of the equipment and apparently This can be dealt with by reducing the volume. In addition, filling pressure can be automatically controlled

As shown in FIGS. 3, 4, 5, 6, and 7, the positions of the rotating bodies 13 and 16 in the fluid are supported by the flexible conductive wires 9 and 18. By holding power with tension and transmitting power with the flexible wire as the rotation axis, 1 the rotating bodies 13 and 16 can hold the position in the direction of gravity by their own buoyancy, so if only the drag of the fluid is pulled and supported from one direction, Because it is good, it is only necessary to join it to a fixed object with a wire rope or the like, and there is no need for a stand or frame for installation. 2 By using the flexible wire that is supported by pulling as the power transmission shaft, the degree of freedom of the installation position of the generator, etc., which is the passive unit, can be improved, and the rotation direction of the rotating body and the twist direction of the rope are matched. In particular, the rotational force and the tension can be transmitted efficiently, and it is easy to obtain and the cost is low. 3. Since the support is a flexible wire, it can be rolled up during transport, making it compact. 4 Since the positioning of the rotating body and the transmission of rotational power are possible with one flexible wire, the plurality of rotating bodies 13 and 20 can be arranged in series, and the superposed torque of the plurality of rotating bodies can be transmitted to the passive unit. . 5. By using a plurality of flexible wires and instructing from multiple directions, three-dimensional positioning is easy, and the tension applied to the flexible wires can be dispersed.

As shown in FIG. 5, FIG. 6, and FIG. 7, when the rotation axis and the flow of the fluid are perpendicular to each other, the drag received by the rotating bodies 16 and 20 is different from that of the axis, so that the rotational transmission is a flexible wire. The line 18 is inclined until the tension direction of the line 18 balances with the buoyancy of the rotating body. In order to compensate for this, the buoyancy increases as the flow velocity increases, and at the same time, the inclination of the rotation axis is made closer to the flow perpendicularly. The function of a vertical wing for freely rotating in the direction of flow on the rotation axis and directing it in the direction of flow and the function of a horizontal wing for imparting bending force and buoyancy to the rotation axis are provided by the stable wing 22.
By acting on, 1 acts to make the inclination of the rotation axis closer to the flow perpendicularly,
It efficiently converts the resistance of the fluid into rotational force. 2 By increasing the buoyancy in proportion to the flow velocity,
Reducing the distance over which 0 flows 3 As shown in FIG. 1, when the generator 1 is built in the rotating body 2, the reaction force against the rotation is canceled by the vertical wing of the stabilizing wing 7. 4 As shown in FIG. 1, when the generator 1 is built in the rotating body 2, the flow direction is adjusted by adjusting the direction of the tension and the angle of the vertical wing of the stabilizing wing 7 with the electric wire 8 and the tension balance. It is possible to control the position orthogonal to. 5 By adjusting the left and right angles of the horizontal wings of the stabilizers 7 and 22 due to the imbalance of the forces applied to the rotating bodies 2 and 20, the posture of the rotating bodies is prevented from becoming unstable. 6 It is also possible to automatically control the vertical and horizontal angles of the stabilizers 7 and 22 to automatically control the positions and postures of the rotating bodies 2 and 20. 7. The vertical and horizontal angles of the stabilizers 7, 22 can be controlled by V-shaped blades. Take the above measures
