DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to the conversion of natural kinetic energy, such as river water currents, tidal currents and wind power, into electrical energy as effective energy, or as a direct power source.
It promotes effective utilization, and relates to a power source using hydropower, wind power, tidal power generation, and natural kinetic energy.

[0002]

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.

[0004]

SUMMARY OF THE INVENTION According to the present invention, in order to recover more kinetic energy, the effective area of a rotating body which is a passive body receiving a fluid flow is increased and the rotating body can be manufactured at low cost. In order to make the structure light and compact at the time of general installation,

FIGS. 1, 3, 5, 5, 7, 12, and 14
As shown by, when the opening area gradually decreases from the flow direction of the fluid or when the fluid flows into the rotating film 2 having the same area, the rotating film 2 expands in a tapered or cylindrical shape due to the drag force of the fluid, and rotates. By having a structure that keeps the shape of the body, 1 When receiving the flow of fluid, the original functional shape can be made, so the amount of material used is minimized and the manufacturing cost can be reduced, especially large size, mass production Sometimes that effect can be demonstrated. 2 Compact when folded for transportation and storage.
It is lightweight and can reduce time cost and labor required for transportation. 3. The adaptation can be easily performed by appropriately selecting the shape of the rotating membrane 2, the strength of the membrane material, and the specific gravity according to the physical properties such as the specific gravity and the viscosity of the fluid and the operating flow rate. 4. When converting weak wind into rotational motion, the inertial weight of the rotating body is a problem. However, since the rotating membrane 2 is a simple membrane, the inertial weight can be reduced by selecting a material. 5 The strength required for the rotating membrane 2 is mainly the stress caused by the drag of the fluid flow, and is mainly transmitted as the tensile stress of the membrane. Therefore, the steel belt, wire,
It is also possible to use a composite material such as Kevlar fiber, glass fiber, or the like, and use a bone structure or the like to reinforce and provide rigidity at a portion where the shape is difficult to maintain by the pressure of fluid. 6 The shape of the rotating membrane 2 is formed by using computer technology such as CAD, CAM, CEA, and three-dimensional molding together with the rotational force and drag from the wing function, so that the shape conforming to the membrane stress and fluid dynamics can be obtained. Calculations can be designed, and even complex shapes can be easily manufactured by connecting them to a flat surface. 7 When an overload that exceeds the film strength of the rotating film 2 occurs, a part of the strength is reduced or an elastic body is used. This can be dealt with by reducing the apparent area.

As shown in FIGS. 1 and 5, the wing function for obtaining the rotational force is constituted by a membrane or a membrane and a reinforcing wire. 3 can be easily designed by integrally designing and joining the parts after development, and the cost is low. 2 The strength required for the rotating membrane 2 is mainly the stress caused by the drag of the fluid flow, and is transmitted mainly as the tensile stress of the membrane. Therefore, the steel belt, wire,
It is also possible to use a composite material such as Kevlar fiber or glass fiber, and to strengthen and have rigidity at a portion where the shape cannot be easily maintained by the pressure of the fluid by using a bone structure or the like. 3 The shape of the rotating membrane 2 is formed by using computer technology such as CAD, CAM, CEA, and three-dimensional modeling together with the rotational force and drag force from the wing function, so that the shape conforming to the membrane stress and fluid dynamics can be obtained. Calculations can be designed, and even complex shapes can be easily manufactured by connecting them to a flat surface. 4 When an overload that exceeds the film strength of the rotating film 2 occurs, a part of the strength is reduced or an elastic body is used. The apparent area can be reduced and this can be dealt with. 5 The blade shape, pitch angle, number of blades and material required
The use of computer technology such as D, CAM, CEA, etc., can be reinforced using composite materials such as steel belts, wires, Kevlar fibers, and glass fibers in areas where strength is required. Shape can be calculated and designed

[0007] As shown in FIG. 3, the wing function is obtained by obtaining a rotational force with a wing shape formed of a rigid material. 1 The fixed wing 7 is opened by the casing effect of the rotating film 2. The fluid that has entered from the section gradually decreases the cross-sectional area of the passage and increases the flow rate, so that the fixed vanes 7 with high power conversion efficiency can be operated efficiently. (2) Since power can be transmitted from the fixed blade 7 via the fixed shaft 8, a structure in which a kinking force is not applied to the tension line 4 can be provided. 3 Since the wing shape itself does not deform, high-speed rotation and high efficiency are possible. 4 The strength required for the rotating membrane 2 is mainly the stress due to the drag of the fluid flow, and is mainly transmitted as the tensile stress of the membrane. Therefore, the steel belt, wire,
It is also possible to use a composite material such as Kevlar fiber or glass fiber, and to strengthen and have rigidity at a portion where the shape cannot be easily maintained by the pressure of the fluid by using a bone structure or the like. 5 The shape of the rotating film 2 is formed by computer technology such as CAD, CAM, CEA, and three-dimensional molding together with the rotational force and the drag force from the fixed wings 7 so that the shape conforms to the film stress and fluid dynamics. Can be calculated and designed, and even complex shapes can be easily manufactured by developing them on a plane and joining them together.

As shown in FIG. 7 and FIG. 12, a plurality of cylindrical or tapered rotating films 2 are twisted together, or as shown in FIG. By configuring the rotating body by the combination of (1) 1 Since the rotating body is constituted only by the shape of the rotating film 2, the structure is simple and the manufacturing is easy. 2. In the case where the rotating film 2 has a twisted shape, the outer periphery of the rotating body also has a spiral shape, and the external flow can be converted into a rotating force. 3. In the case of the shape shown in FIG. 7, the position where the bracket 11 and the rotating film 2 are hung by the tension line 4 does not become circular, so that the tension line 4 is hardly twisted when rotated. 4. Since there is no wing shape serving as a fluid resistance inside the rotating film 2, the fluid drag resistance is small. 5 The strength required for the rotating membrane 2 is mainly the stress caused by the drag of the fluid flow, and is mainly transmitted as the tensile stress of the membrane. Therefore, the steel belt, wire,
It is also possible to use a composite material such as Kevlar fiber or glass fiber, and to strengthen and have rigidity at a portion where the shape cannot be easily maintained by the pressure of the fluid by using a bone structure or the like. 6 Change the shape of the rotating body 2 to CA
By forming membranes using computer technologies such as D, CAM, CEA, and three-dimensional molding, it is possible to calculate and design shapes that conform to membrane stress and fluid dynamics. Even complex shapes can be developed and connected to a plane. Can be easily manufactured. 7 If an overload that exceeds the film strength of the rotating body 2 occurs, reduce the strength of some parts or configure it with an elastic body. If an abnormal force is applied, some breakage or elastic deformation may occur. This can be dealt with by reducing the apparent area.

As shown in FIG. 9, a wing-shaped wing blade 12 is formed on a tension line 4 for suspending the rotator and the rotation shaft, partly or over the entire length. Since it is composed only of the shape, the structure is simple and the production is easy. 2 Efficiency is improved because a rotational force can be applied in combination with other methods. (3) Since the wing blades 12 can provide rigidity to the tension line 4 for suspending the flange 5 and the rotating membrane 2, the tension line 4 is hardly twisted when rotated. 4. Since there is no wing shape serving as a fluid resistance inside the rotating film 2, the fluid drag resistance is small.

As shown in FIG. 11, by using a rotating shaft having flexibility capable of transmitting a rotating force to a part between the rotating body and the output shaft, 1 the generator 1 or the power unit is installed. The position can be freely set, the structure is simple, and the cost can be reduced. (2) Even if the direction of the fluid flow changes, the rotational force can be transmitted to the fixed shaft by following the rotating body in any direction due to the bending of the shaft. (3) The shape of the flexible rotating shaft 13 can be determined by designing the shaft to be bent as a hollow taper, and a multi-stage extending type structure such as a fishing rod can be adopted as in a fishing rod, and can be made compact when not in use. 4. When the rotation torque is large, the flexible portion of the flexible rotary shaft 13 can be used by connecting the flexible shaft joints in series in multiple stages. The above measures are taken alone or in combination.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structural features of the embodiment will be described with reference to the differences between the embodiments.

FIG. 1 is a sectional view of a membrane airfoil, and FIG. 2 is a front view of the membrane airfoil. In response to the flow of the fluid, the inner surface of the rotating film 2 having a cylindrical shape like a streamer
A plurality of rotating membrane blades 3 that receive a flow of fluid and convert it into a force in a rotating direction like a sail of a yacht are formed, and a plurality of tension lines 4 are provided from an outer periphery of a flange 5 fixed to an input shaft of the generator 1. It is hung on the opening of the rotating film 2. When there is no fluid flow, the rotating membrane 2 and the rotating membrane blade 3 are
, The fluid flow speeds up, the rotating film 2 flows, and when the fluid enters through the opening, the fluid is formed on the inner surface while maintaining a tapered or cylindrical shape due to a drag. The rotating film blades 3 are mutually pulled by a hub 6 at the center of rotation to form a wing shape.
The fluid that has entered the rotary membrane 2 passes through the rotary membrane blades 3 to generate a rotational force and transmits it to the rotary membrane 2. The rotary membrane 2 transmits torque to the flange 5 by a tension line 4 by its own tension. At this time, when the tension line 4 is a flexible line, the diameter of the flange 5 is kept in a state of tension by the balance between the torque generated by the rotating body and the drag,
Set so that the tension line 4 is not twisted. This can be prevented by providing the tension line 4 with rigidity. The characteristics are the same as those of the axial flow multi-blade type, and a rotating force can be efficiently obtained even at a low flow velocity. Lighter membranes are better suited for low-speed flows, have less elongation for shape stability, have higher tensile strength, and have a surface that has less frictional resistance with the fluid.If the surface does not need to be folded, it should be rigid. It may be made of a certain thin plate. In addition, since the strength of the connecting portion of the hub 6 is weak and the connecting portion can be reversibly connected, it can be easily used as a protection structure at the time of overload. Similarly, the pressure receiving area of the rotating membrane blade 3 can be reduced by deformation of the elastic body. It can also be reduced, and by using a structure that can reversibly bond a part of the rotating film 2 such as Velcro (registered trademark), the part is peeled off by overload and the shape of the rotating body is maintained. It can be lost.

2 FIG. 3 is a cross-sectional view of the fixed airfoil, and FIG. 4 is a front view of the fixed airfoil. A fixed wing 7 that receives the fluid flow and converts it into a force in the rotational direction is fixed to the outlet side of the rotating film 2 that has a tapered or cylindrical shape like a streamer. It is hung from the outer periphery of the flange 5 fixed to the shaft to the opening of the rotating film 2 via a plurality of tension lines 4. When there is no flow of the fluid, the rotating membrane 2 and the rotating membrane blades 3 hang down in the direction of gravity at the tension line 4 from the flange 5. When the fluid enters through the opening, the fluid progresses while maintaining a conical shape due to the drag, and at the same time, the fluid has a reduced cross-sectional area to increase the flow velocity.
The rotating membrane 2 transmits torque by its own tension to the tension line 4.
To the flange 5. Further, transmission is also possible by directly connecting the fixed wing 7 and the flange 5 with a fixed shaft 8. At this time, when the tension line 4 is a flexible line, the diameter of the flange 5 is set so as to keep the tension line in balance with the torque generated by the rotating body and the drag, so that the tension line 4 is not twisted. This can be prevented by providing the tension line 4 with rigidity. Characteristically, it is possible to use an airfoil with an efficiently designed shape similar to the axial flow type inside the casing interior, and it is possible to respond to a relatively low flow velocity by increasing the flow velocity passing through the wing .

3 is a cross-sectional view of the swirling blow-off type and FIG. 6 is a front view of the swirling blow-out type. This is explained. Outlet 10 and a plurality of nozzle membranes 9 are formed in such a manner as to turn the flow of air in the same rotational direction, and the rotating membrane 2 is connected to the outer periphery of the flange 5 fixed to the input shaft of the generator 1 via a plurality of tension lines 4. To the opening. When there is no flow of the fluid, the rotating film 2 and the nozzle film 9 hang down in the direction of gravity at the tension line 4 from the flange 5, but the flow of the fluid becomes faster and the rotating film 2 flows and the fluid flows. When it enters through the opening, it keeps a hemispherical shape due to the drag and blows out as a swirling flow from the nozzle film 9 formed on the inner surface. . At this time, when the tension line 4 is a flexible line, the diameter of the flange 5 is set so that the tension line 4 is kept in tension by the balance between the torque generated by the rotating body and the drag, so that the tension line 4 is not twisted. This can be prevented by providing the tension line 4 with rigidity. Characteristically, the shape of the rotating film 2 can be maintained at a low flow rate, and by adjusting the ejection port 10 and the nozzle film 9 and rotating at a low speed, the rotating film 2 can be formed in a simple shape, an advertisement, etc. can be placed. It can also be used for visual advertisements.

FIG. 7 is a side view of the spiral type, and FIG. 8 is a front view of the spiral type. A bracket 11 fixed to the input shaft of the generator 1 is attached to the rotating membrane 2 having a plurality of spirally formed cylindrical or tapered shapes such as a streamer.
It is hung on the opening of the rotating membrane 2 via a plurality of tension lines 4. When there is no fluid flow, the rotating membrane 2 is
Although it is in a state of hanging down in the direction of gravity at the tension line 4 from 1, the flow of the fluid becomes faster, the rotating membrane 2 flows, and when the fluid enters from the opening, the fluid passes through the spiral flow path. The torque is transmitted to the bracket 11 by the tension line 4 by the tension of the rotating membrane 2 by the reaction force. At this time, when the tension wire 4 is a flexible wire, the bracket 11
Is maintained in a state of tension by the balance between the torque and the drag generated by the rotating body, and the tension line 4 is set so as not to be twisted.
This can be prevented by providing the tension line 4 with rigidity. Further, the same effect can be obtained even when the rotating film 2 has a double structure and the partition film is spirally formed in the donut-shaped opening, and the flat film can be developed by a simple developing method. Even in high-speed flow, resistance due to drag is small, and efficiency is high for objects having a relatively large specific gravity of fluid.

5 FIG. 12 is a side view of the spiral reinforcement type and FIG.
FIG. 3 shows a front view of the spiral reinforcement type, which will be described. A cylindrical or tapered shape such as a streamer is formed with a plurality of spirals, and the opening of the rotating film 2 is bordered by a reinforcing line 16,
The reinforcing wire 16 is bundled at the rotation center and connected to the input shaft of the generator 1. The reinforcing wire 16 retains the shape of the opening and transmits rotational torque by means of an elastic wire rope or the like. When there is no flow of the fluid, the rotating membrane 2 hangs down in the direction of gravity from the input shaft of the generator 1 at the reinforcing line 16, but the flow of the fluid becomes faster and the rotating membrane 2 flows and the fluid flows. When it enters from the opening, it passes through the spiral flow path, and transmits the torque to the input shaft of the generator 1 by the reinforcing wire 16 by its own tension due to its reaction force.
The opening of the rotating film 2 is shaped as an inclined cut by the reinforcing wire 16 so that the fluid can easily flow in and has a function of stabilizing the shape. In addition, the rotational force can be transmitted by fixing the rotation center of the rotating film 2 to a fixed shaft or a tiltable shaft. The structure is simple and there is little drag due to drag even at high speeds.

6 FIG. 14 shows a side view of the spiral partition type, and FIG. 15 shows a front view of the spiral partition type, which will be described.
Rotating film 2 having a cylindrical or tapered shape such as a streamer
A spiral partitioning film 17 is formed inside the
The oblique side is bordered by the reinforcement line 16, and the reinforcement line 1 is set at the center of rotation.
6 are connected to the input shaft of the generator 1. The reinforcing wire 16 retains the shape of the opening and transmits rotational torque by means of an elastic wire rope or the like. When there is no fluid flow,
The rotating membrane 2 hangs in the direction of gravity from the input shaft of the generator 1 at the reinforcement line 16, but when the fluid flows faster and the rotating membrane 2 flows and the fluid enters from the opening, the spiral membrane 2 has a spiral shape. , The torque is transmitted to the input shaft of the generator 1 by the reinforcing wire 16 by the self-tension of the rotating membrane 2 by the reaction force. The shape of the opening of the rotating film 2 is maintained by the reinforcing wire 16 so that the fluid can easily flow in and has a function of stabilizing the shape. Further, the rotational force can be transmitted by fixing the rotation center of the partition film 17 to a fixed shaft or a tiltable shaft. The structure is simple, the resistance due to drag is small even in high-speed flow, and the helical pitch of the partition film 17 is easily reduced structurally.

FIG. 9 shows a side view of the wing blade type, and FIG. 10 shows a front view of the wing blade type. A blade blade 12 having a blade cross-sectional shape is attached to the tension line 4 suspended from the outer periphery of the flange 5 fixed to the input shaft of the generator 1 through the plurality of tension lines 4 to the opening of the rotary film 2 from the rotating film 2. Attach. When there is no flow of the fluid, the rotating membrane 2 and the blades 12 hang down in the direction of gravity from the flange 5 along the tension line 4, but the flow of the fluid becomes faster and the rotating membrane 2 flows and the fluid flows. When the blade enters through the opening, the blade 12 expands so as to open the umbrella, and the expanded blade 12 receives the flow of the fluid, generates rotational force, and transmits it to the flange 5 by the tension line 4. It mainly has the function of preventing kinking when the tension line 4 is formed with a rope having low rigidity, but the fluid resistance of the tension line 4 can also be converted into rotational force, and the outer shape of the flange 5 can be reduced. .

8 FIG. 11 is a view showing the installation of the flexible shaft, which will be described. Flexible rotary shaft 1 coupled to input shaft of generator 1
3 is supported by a bearing 14 provided on a gantry 15, and the rotating membrane 2 is connected to a tip end of the rotating membrane 2 by a tension line 4 via a flange 5.
Hang. The flexible rotating shaft 13 has a structure like a fishing rod, which becomes thinner toward the tip from the root portion and is more easily bent toward the tip. When there is no fluid flow, the flexible rotating shaft 13 is substantially vertical and the rotating membrane 2 is hanging down from the flange 5 in the direction of gravity at the tension line 4. When the fluid flows and the fluid enters through the opening, the rotating membrane 2 expands to open the umbrella, and receives the drag of the fluid of the developed rotating membrane 2, and the flexible rotating shaft 13 elastically bends in the flow direction of the fluid. The opening of the rotating membrane 2 can be always made to follow the flow direction of the fluid by transmitting the rotation force and bending in the flow direction. In addition, a flexible shaft, such as a wire rope, capable of transmitting torque, a coil spring shaft joint, a universal joint connected in multiple stages, a bevel gear box, and the like, are added to the rigid shaft as the flexible rotating shaft 13. The same effect can be obtained. With this structure, in the case of wind power, the flexible rotary shaft 13
It is possible to guide the rotating body to an arbitrary position by setting the rotating body vertically and hydraulically horizontally, and by replacing the rotating body, wind, hydraulic,
The conditions of the flow velocity can be adjusted. In addition, the integral structure of the rotary shaft in the spiral reinforcement type shown in FIG. 12 and the spiral partition type shown in FIG. 14 simplifies the overall structure. As described above, each of the structures and features can be adapted to various environments depending on the structure, combination of functions, and constituent materials.
