Description

Plate coil power generation device having a plurality of plate coil segments {A GENERATION INSTALLATION OF PLATE COIL INCLUDING A PLURALITY OF PLATE COIL SEGMENTS}

The present invention relates to a power generation device that generates power using the rotational force caused by fluid flowing in a plate coil. In particular, a plate coil is formed long in a fluid with a flow rate by successively mounting several plate coil pieces on a rotating shaft, It relates to a plate coil power generation device having a plurality of plate coil pieces, characterized in that rotational force is easily and efficiently obtained with a plate coil in a flowing fluid, and then the power is transmitted through a connected steel bar wire to generate power in a generator.

Existing power generation equipment is fixed, equipped with expensive facilities and equipment, and generates power on a relatively large scale. However, there are limitations in power generation locations, high costs, and access to energy production is rare, so anyone can generate power. As this is not possible, there is a very difficult problem in acquiring renewable energy from nature due to difficulties in supplying it.

Meanwhile, generally flowing fluids have kinetic energy expressed as E=(1/2)mv². Since kinetic energy is proportional to the square of mass and velocity, water has a mass per volume of 1,000 compared to air at the same flow rate. Because the ship is large, the amount of power generated from flowing water is quite large. However, there were many limitations in using it, and there were problems in that it was difficult to handle easily due to a lack of power generation resources due to environmental issues. However, recently, large water flows (hereinafter simply referred to as “water currents”) in tides, ocean currents, or relatively large rivers, etc. Many ideas have been proposed for small hydro power generation, which generates power using natural energy.

For example, as the first prior art, Republic of Korea Patent Publication No. 10-2010-0093561 (water current power generation device), as shown in FIG. 1, includes an underwater rotating body 32 rotated by a water current 11, and the above The driving side hydraulic pump 34 supports the front end 52 of the underwater rotating body 32 at a predetermined position in the water, and the rotational power of the underwater rotating body 32 supported by the driving side hydraulic pump 34 It is provided with a power transmission unit 40 that transmits to the upper part of the water surface (9), and a generator 39 that is driven by the power transmitted by the power transmission unit 40 and is disposed above the water surface. The entire body 32 includes a fuselage 51 that has a streamlined shape from the front end to the rear end, and intersects the axial direction of the underwater rotor 43 between the front end of the fuselage 51 and the driving side hydraulic pump 34. A water current power generation device capable of stable power generation over a long period of time is proposed by having a support portion 33 capable of swinging in a direction such as that and a plurality of wings 54 protruding radially from the periphery of the fuselage portion 51.

However, in the first prior art, a rotating body of a considerable size, a power transmission means, and a generator of a considerable size must be separately provided, and due to the nature of the power transmission unit, it must be placed on a fixed device arrangement part 3, so it is suitable for small ships. It is understood as a power generation device that exceeds the size that can be built.

Moreover, in order to produce significant power, many underwater rotating bodies must be installed, which ultimately results in the overall device becoming large, which has the limitation that efficiency is not very high compared to the size of the entire device.

Meanwhile, as a second prior art for a small hydro power generation device that can be applied to small ships, there is one such as Republic of Korea Patent Publication No. 10-2017-0066062 (Ocean Current Power Plant).

As shown in FIG. 2, the ocean current power generation device 10 of the second prior art includes a wing portion 100, a wire portion 200 connected between the wing portion 100 and the hull 2 to provide tension. ), a rotating part 300 installed on the hull 2 to convert the tension of the wire part 200 into rotational force, and a rotating electrical machine 400 axially coupled to the rotating part 300. The wing unit 100 can flow in water, and the ocean current power generation device 10 rotates the rotating unit 300 by the tension of the wire unit 200 connected to the wing unit 100 and rotates by the rotational force of the rotating unit 300. The electric machine 400 operates to generate power.

The ocean current power generation device 10 of the second prior art has a structure in which the wing portion 100 is connected to the hull 2 through the wire portion 200, and the wing portion 100 can easily flow along the flow of seawater. It is formed in the shape of an airfoil/hydrofoil. Accordingly, tension is generated in the wire portion 200 in response to the flow of the wing portion 100, and the rotating portion 300 connected to the wire portion 200 can be easily rotated by the tension. The ocean current power generation device 10 of the second prior art is formed in a structure that can easily convert seawater flow or dynamic pressure corresponding to seawater flow into rotational force.

In particular, the rotating part 300 transmits rotational force to the rotating electric machine 400 mounted on the hull 2 to induce rotation of the rotating electric machine 400. Through this, power is generated by the electromagnetic induction action of the rotating electric machine 400.

The rotating electric machine 400 is a concept that includes both an electric motor and a generator, and the ocean current power generation device 10 can produce electric power using an electric motor and generator mounted on the hull 2.

In addition, the wings 100 are formed in a shape corresponding to the shape of the hull 2, so that they can be easily attached and detached from the hull 2 and are easily stored in the hull 2. Because of this, the ocean current power generation device 10 can be very easily applied to the ship 1 without damaging the space of the hull 2, such as the deck, and with minimal deformation of the hull 2 or combination of appendages. In addition, the wing unit 100 can use the tension of the wire unit 200 and the rotational force of the rotating unit 300 by adjusting the direction or trajectory of the flow in the water as desired.

However, in the above second prior art, the wing part 100 generates tension in the wire part 200 to rotate the rotating part 300, so there is a problem of having to fit the wire again after power generation, and of course, the size It can't help but grow.

Moreover, since the efficiency of hydroelectric power generation is ultimately generated by rotational force, the method of connecting wires causes a lot of resistance, which is undesirable in terms of efficiency compared to the size of the overall device.

Accordingly, the present inventor has proposed Republic of Korea Patent No. 10-2239224 (name: plate coil power generation device) to solve the problems of the above prior arts.

The patented technology of the present inventor is described as a third prior art with reference to FIGS. 3 to 7 as follows.

Figure 3 is a schematic perspective view of the plate coil power generation device of the third prior art, and Figure 4 is a diagram explaining the operation of the steel bar wire of the plate coil power generation device of the third prior art. First, referring to Figure 3, the third prior art The plate coil power generation device 100 according to is mounted on the plate coil portion 10, which obtains rotational force by water flow, and the support body ("C") of a power generation device such as a ship or floating body, and uses the rotational force of the plate coil portion 10 as electric power. It consists of a power generation unit 40 that converts the power generation unit 40 into a power generation unit 40, and a connection unit 30 that transmits the rotational force of the plate coil unit 10 to the power generation unit 40.

The plate coil unit 10 is made of a plate coil 12 and a steel bar 11 used as a rotation axis of the plate coil 12, and the power generation unit 40 includes a generator 41 and a generator as a power generation device. It is composed of a fastening device such as a fastening bolt 42 mounted on the support ("C") and an electric wire 43, and the connection part 30 is physically axially coupled to the plate coil part 10 to transmit rotational force. It consists of a steel bar wire 31 and a flange 32 that axially couples the steel bar wire 31 and the steel bar 11 of the plate coil portion 10. At this time, the flange 32 has a diameter greater than the diameter of the flange body. The bracket 32a can be integrally formed in the form of a disk with a larger diameter or joined by a method such as welding.

Now, as shown in FIG. 3, the plate coil portion 10 sufficiently immersed in the water flow is rotated by the water flow. For example, the plate coil 12 has a left-hand screw (counterclockwise screw) shape when viewed from the flange 32 side. When combined to rotate, when the water flow direction is toward the left in the drawing (see arrow "A"), the steel rod (11) receives the same resistance as the right-hand screw, so it rotates clockwise when viewed from the flange (32) side. It rotates (see arrow "B"). Subsequently, the rotational force of the steel rod 11 rotates the steel rod iron 31 axially coupled through the flange in the same direction, and this rotational force causes the generator 41 generates power and transmits it to where it is needed through the wire 43.

Next, the function of the connecting portion 30 (particularly, the steel bar wire 31) will be described with reference to FIG. 4 . To explain the configuration of the connection part 30 again, as shown in FIG. 3, the steel bar wire 31 is axially coupled to the top of the flange 32, and then the plate coil part 10 assembled through the steel bar wire 31 is placed in water. When immersed in water with no flow rate, the plate coil body 10 is directed vertically downward due to its weight. At this time, the steel bar wire 31 is made of strong steel with a predetermined diameter and has a certain degree of elasticity. It is manufactured to have

Figure 4 is a diagram explaining the operation of the steel bar wire of the plate coil power generation device of the third prior art. Figure 4 (a) is a view of the plate coil power generation device 100 from above at the moment the flow rate starts, and in Figure 4 (a) b) is a view from above of the plate coil power generation device 100 assuming that the plate coil 12 is only pushed when rotated clockwise when viewed from above due to the flow rate, and (c) in Figure 4 shows the flow rate is the upward force. This is a view from above of the plate coil power generation device 100 in a stable balanced state by receiving (the force of "S" in Figure 4(b)).

In a state where there is no flow rate, the unfolded plate coil (12) stands vertically and takes on a spiral symmetrical shape. In other words, it is in a state of being submerged in water and does not flow, so it remains in that state. However, if the water flows with a velocity, the plate coil (12) is pushed back due to drag from the flowing water and cannot remain vertical, and the water When viewed from the front, the plate coil 12 has an inclined shape with the lower part pushed further back, as shown in Figure 4 (a). This is because the upper part is held by the steel bar wire (31) from the generator (41). Again, if the vertical screw-shaped plate coil 12 receives the flow speed of water head on, (c) in FIG. 4 in the drawing state of the third prior art is in a state where the flow speed is seriously increased, so the case of FIG. 3 Likewise, the left side of the plate coil 12 of the third prior art will try to rotate clockwise when viewed from above, and the right side of the plate coil 12 will try to rotate counterclockwise when viewed from above. However, since the left and right areas are the same, the left side is pushed down and tries to rotate clockwise, and the right side is lifted up and tries to rotate counterclockwise, so the forces are canceled out because of the same shape and area, making rotation difficult.

In the end, as mentioned above, the plate coil (12) is pushed back due to the drag force from the flowing water and cannot remain vertical, and when viewed from the front where the water flows, the plate coil (12) has an inclined shape with the lower part being pushed further back. This happens. Then, this time, in the screw shape in the case of FIG. 3, the left side of the plate coil 12 appears wider and the right side appears flatter and smaller. This is due to the shape of the screw, which is caused by the shape of the left-hand screw when viewed from above, and in the shape of the right-hand screw when viewed from above, as mentioned above, the plate coil (12) is pushed back due to the drag force from the flowing water and is vertical. If it cannot be maintained and the plate coil (12) has an inclined shape where the lower part is pushed further back when viewed from the front where the water flows, the shape of the screw on the right side of the plate coil (12) is wider when viewed from the front where the water flow is flowing. It is visible and the left side is flat and looks small. Returning to the drawing as shown, the screw shape on the left side of the plate coil (12) appears wider and the right side appears flatter and smaller, resulting in a difference in drag. This generally means that the larger the slope, the larger the difference. Due to the left and right difference in drag, the plate coil 12 receives a rotational force and rotates. The weight of the plate coil (12) balances the flow rate of water, and the lower part of the plate coil (12) is pushed back and tilted, and the plate coil (12) continues to rotate clockwise.

That is, since the left wing of the plate coil 12 receives more force due to the flow rate, the plate coil 12 is pushed to the right, and is pushed from the state (a) to (b) in FIG. 4. Then, there may be a change in the inclination angle, but there is no significant difference in the rotational force. Continuing, in the state (b) of FIG. 4, due to the fluid flow (“A”), the “S” area is subjected to a resistance force of the flow velocity that pushes back, and the plate coil (12) is pushed to the left, ultimately causing the left wing to move against the flow velocity. The plate coil 12 is balanced at the point where the force pushing to the right of the force received by the force and the force pushing to the left of the force received due to the fluid flow in the "S" region in the state (b) of FIG. 4 are balanced. It stops (see (c) of FIG. 4), and the plate coil 12 continues to obtain a relatively large rotational force by withstanding the flow speed and low drag force. This rotational force leads to power generation.

For reference, the energy of the flow of water is high, so the energy of the same flow of water is about 840 times the energy of the air flow, and a large amount of energy can be obtained. By rotating the steel bar wire (31) with the large rotational force of the plate coil (12), large power can be obtained from the generator (41). In particular, in the case of the plate coil 12 of the third prior art, the number of rotations of the screw blade blades is high, enabling more efficient power generation than a general propeller-type water turbine generator.

Now, a plate coil power generation device according to an embodiment of the third prior art will be described in detail with main reference to FIGS. 5 and 6 and auxiliary reference to FIG. 7. Figure 5 is a front view of a plate coil power generation device according to an embodiment of the third prior art, where Figure 5 (a) is a weight control part, Figure 5 (b) is a plate coil part and a connection part, and Figure 5 (c) ) is the right side view of the connection. In addition, FIG. 6 shows a partial cross-sectional view of the plate coil portion and the connecting portion and an enlarged cross-sectional view of the connecting portion in FIG. 5(b) of the plate coil power generation device according to the embodiment of the third prior art. Figure 7 is a component diagram of a plate coil power generation device according to another embodiment of the third prior art, and is also referred to in this embodiment.

As shown in FIGS. 5 and 6, the plate coil power generation device according to an embodiment of the third prior art is composed of a plate coil portion 10, a connection portion 30, and a power generation portion 40, and preferably the weight An adjuster 20 can be added.

First, as shown in Figure 5, the helical-shaped plate coil 12 is supported on a steel bar 11 serving as a support axis, and the steel bar 11 is axially connected to the steel bar wire 31 through the flange 32. It is combined. The material of the steel rod 11 is preferably a rod or bar made of a hard material such as steel, but it is not necessarily limited to this, and any other material that is somewhat solid may be used, and in some cases, may be somewhat flexible. You can also use a material with .

The plate coil 12 may be a fixed type fixed to the steel rod 11, but more preferably, it is foldable like a plate coil spring as in the embodiment of FIG. 7 in terms of portability and storage.

Regardless of whether it is a fixed type or a folded type, it is preferable that one end (right side in FIG. 5) of the plate coil 12 is formed with a plate coil extension portion 12a and fixed to the flange 32 by welding or other methods.

More preferably, a disk-shaped bracket 32a having a diameter larger than the flange body diameter is installed on the flange 32 integrally with the flange body or fixed to the flange body by welding or other methods. In this case, the plate coil It is preferable that the extension portion 12a is curved along the flange 32 body and the bracket 32a so that it is firmly fixed to the flange body as well as the bracket by welding or the like. This is because the other end (left side in FIG. 5) of the plate coil 12 must be fixed to the steel bar 11 with a fixing pin 13, so that the plate coil 12 is completely fixed to the steel bar 11. This is because, in the case of a method that does not work, the resistance to the water flow of the plate coil 12 will be concentrated on one (right) end.

Also preferably, it is desirable to add a weight control unit (20: see (a) in Figure 5) to the other (left) end of the plate coil (12: see (b) in Figure 5), and a weight is added to the other (left) end of the plate coil (12: see (b) in Figure 5). This is because it needs to be hung and fully submerged in the water flow, or conversely, if the coil part is too heavy, it is necessary to suspend the floating body to prevent it from being submerged too much. Therefore, in Figure 5 (a), the weight control device 21 can be a weight with a greater specific gravity than the fluid or, conversely, a floating body with a smaller specific gravity than the fluid. In the weight control unit 21, a protruding fastening bolt 23 fastens the weight control unit formed on the distal plate coil located at the other (left) end of the plate coil 12 (see (b) in FIG. 5). It is required to fasten to the groove 14, and it is possible to fasten using a fastening nut 23, for example.

However, in this embodiment, when the plate coil 12 itself is made of a solid material or when the plate coil portion 10 is deployed on its own by attaching a weight as a weight control device 21 to the distal end, the steel bar 11 ) Rotation and power generation by water flow are possible even without (see (c) in Figure 7). In addition, if manufactured in the same manner as a compression spring so that it can be expanded to a certain extent as shown in (c) of FIG. 7 even if no external force is applied and can be folded as shown in (a) of FIG. 7 by applying an external force, the weight of the plate coil 12 itself becomes Therefore, it is possible to generate power without the weight control device 21, thus promoting user convenience (in this case, the plate coil 12 is folded by applying an external force from the outside to the inside, and tied with a wire, etc. to increase the volume). After reducing it, it can be stored and transported).

Now, with reference to FIG. 6, the coupling structure of the plate coil part 10 and the connection part 30 will be described in detail.

As shown in FIG. 6, a threaded portion 11a for coupling the steel rod 11 and a threaded portion 32b for coupling the steel rod wire 31 are formed on the left and right sides of the flange 32 of the connecting portion 30, respectively, and each matching the threaded portion. Male threaded portions (11a, 31a) are formed at the ends of the steel rod (11) and the steel rod wire (31) so that the threaded portions are first coupled to each other, and fixing nuts (33) are fastened thereto. At this time, when assembling the steel bar 11 through the threaded portion toward the plate coil, it is preferable to assemble the screw in the same direction as the rotation direction of the plate coil 12 (left-hand thread in FIGS. 5 and 6). When the plate coil 12 rotates counterclockwise when viewed from the flange 32, the steel bar 11 becomes a right-hand screw (in Figures 5 and 6, since it rotates clockwise when viewed from the flange 32, the plate coil ( 12) rotates clockwise in the direction of fluid flow ("A"), so the steel bar thread portion (11a) must be left-handed to function as a lock as the plate coil (12) rotates and develops. In addition, the flange 32 and the steel bar wire 31 are coupled in a manner similar to the above.

Meanwhile, a plate coil extension 12a is formed at one end of the plate coil 12 (left side of the flange 32), and the plate coil extension 12a is welded to the flange 32 or other methods. To be combined, more preferably, a disk-shaped bracket 32a with a diameter larger than that of the flange body is formed, the plate coil extension portion 12a is bent at a right angle, and then the plate coil extension portion 12a is bent at a right angle and then connected to the flange 32 body. In terms of robustness, it is preferable to allow multiple places to be coupled to the bracket 32a at the same time. The body of the flange 32 and the bracket 32a may be formed integrally, or may be formed separately and then combined.

The non-illustrated symbol 39 is a welded portion, and the welded portion is a welded portion between the bracket 32a and the plate coil extension portion 12a as shown in FIG. 6, as well as the flange 32 body and the bracket 32a as shown in FIG. 5. If these are to be formed separately and then joined, it may be necessary to form multiple welds.

Afterwards, the other end of the steel bar wire 31 is coupled to the generator 41 in a known manner, and thus the plate coil part 10 rotates according to the fluid flow (“A” in FIG. 3) and is axially coupled through the flange. The steel bar wire 31 rotates and drives the generator 41 of the power generation unit 40 connected to the steel bar wire 31 to produce electricity and transmit the electricity to the electric wire 43.

Now, a plate coil power generation device according to another embodiment of the third prior art will be described in detail with main reference to FIG. 7 and auxiliary reference to FIGS. 5 and 6 described above. Figure 7 is a part diagram of a plate coil power generation device according to another embodiment of the third prior art. Figure 7 (a) is a left side view, a front view, and a right side view of the plate coil 12 and flange 32 combination from the left. 7(b) is a diagram of the steel bar 11. Figure 7 (c) is a perspective view of the plate coil deployed after the steel bar wire 31 is coupled to the plate coil and flange combination in Figure 7 (a), and Figure 7 (d) is a weight control unit. This is the drawing of (20).

The biggest advantage of the plate coil power generation device according to this embodiment can be said to be portability. As shown in Figure 7, the plate coil power generation device according to this embodiment is composed of the plate coil portion 10, the connection portion 30, and the power generation portion 40, which is the same as the existing principle of the third prior art described above. , in the plate coil power generation device according to the present embodiment, as shown in (a) of FIG. 7, the plate coil 12 is stored in a state where the plates overlap when no external force is applied, such as a helical spring. It is portable.

Therefore, when attempting to use the plate coil power generation device of this embodiment, first, while expanding the plate coil 12 as shown in (c) of Figure 7, a steel rod (12b) is inserted into the steel rod insertion hole (12b) of the plate coil (12). 11) is inserted and coupled to the flange 32 as shown in FIG. 6, and the fixing pin 13 is inserted into the pin insertion hole 11b so that the plate coil is fixed without being folded anymore. Thereafter, if necessary, the weight control unit 20 as shown in (c) of FIG. 7 is mounted on the weight control unit fastening groove 14.

That is, in the case of this embodiment, the plate coil extension portion 12a extending from one end of the plate coil 12 is bent and coupled to the body of the flange 32 and the bracket 32a by welding, etc., and stored and carried. If the other side of the plate coil 12 is left as is without applying force, it becomes flat and small in size as shown in (a) of FIG. 7, making it easy to store and carry. On the other hand, when used as a small hydro generator, if the plate coil is artificially or by its own load, it becomes as shown in (c) of FIG. 7. The plate coil (11) has a steel rod insertion hole (12b), which is a hole slightly larger than the thickness of the steel rod (11), penetrating in the center, and the plate coil (12) can be extended to insert the steel rod (11) into this hole. will be.

The connection method of the steel bar 11 and the flange 32 is the same as in Figures 5 and 6. Just combine them, and as shown in FIGS. 5 and 6, the plate coil 12 can be fixed to the pin insertion hole 11b at the other (left) end of the steel bar 11 with a fixing pin 13.

Naturally, as a modification of this embodiment, the connection between the main flange 32' and the plate coil extension portion 12a of the plate coil portion 10 may be coupled by a separate detachable method rather than a fixed method such as welding.

According to the third prior art, power generation is possible regardless of location wherever there is a flowing fluid, and rotational force is obtained through a plate coil in which a plurality of blades are arranged in succession along the axial direction on one rotation axis. It is possible to produce highly efficient small hydro power generation, which has a great advantage in renewable energy and energy production because it has an efficient energy replacement effect compared to existing power generation devices and produces electricity that can be used in daily life and industry. Moreover, as shown in Figure 7 If the plate coil can be folded as in the embodiment, it has the additional advantage of being portable as simple and portable power generation equipment, and anyone can easily use it, enabling small hydro power generation at a low cost per unit of power generation. .

However, in the case of the third prior art, when the foldable plate coil 12 is made of a solid material such as metal, if no external force is applied, it is allowed to unfold to some extent as shown in (c) of FIG. 7 and an external force is applied. If it is manufactured in a manner such as a compression spring to enable folding as shown in (a) of 7, the convenience of the user can be improved in various ways, but when storing, the plate coil (12) is folded by applying an external force from the outside to the inside. Since it has to be fixed with a wire, etc., it is inconvenient during storage and may also be deformed during the storage process. Above all, if the plate coil made of metal has a certain thickness, it does not fold easily, making it somewhat difficult for women or the elderly to handle. There was a problem that it was dangerous.

Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings so that those skilled in the art can easily implement the present invention. However, the present invention may be implemented in various different forms and should not be construed as limited to the embodiments described herein, but is provided to provide a more complete explanation to those skilled in the art.

Prior to the detailed description of the present invention, components that are the same or correspond to those in the third prior art among the drawings are given the same or similar reference numbers, and detailed descriptions of related known configurations or functions may obscure the gist of the present invention. In cases where it is judged, the detailed description will be omitted.

(First Example)

Hereinafter, the first embodiment of the present invention will be described in more detail with reference to FIGS. 8 to 10 of the attached drawings.

Figure 8 is an exploded perspective view of the plate coil power generation device according to the first embodiment of the present invention, Figure 9a is a perspective view of the assembled state of the plate coil power generation device according to the first embodiment of the present invention, and Figure 9b is the plate coil power generation device according to the first embodiment of the present invention. It is a partial cross-sectional view of the plate coil connection part used in the plate coil power generation device according to Example 1, and Figure 10 is a perspective view of the plate coil used in the plate coil power generation device according to the first embodiment of the present invention in a folded state.

First, the plate coil 110 used in the plate coil power generation device according to the first embodiment of the present invention, as shown in FIGS. 8 to 10, has an overall inner diameter relatively close to the outer diameter of the steel bar 120. It is a plate coil having inner peripheral portions (111b, 112b, 113b) forming a helical shape with a small radius and outer peripheral portions (111a, 112a, 113a) forming a helical shape with a larger radius than the inner peripheral portion. The difference is that it is separated into a plurality of plate coil pieces. In this embodiment, it is made up of three plate coil pieces (111, 112, 113) that rotate once (360 degrees), but it does not necessarily have to be three, and one plate coil piece must rotate once (360 degrees). Neither.

However, since there is a difference in shape between the outermost plate coil piece and the middle plate coil piece, each plate coil piece will be described in detail with reference to FIGS. 8, 9A, and 10.

First, the front plate coil piece 111 has an inner peripheral portion 111b that has a helical shape with a relatively small radius and an inner diameter that is approximately close to the outer diameter of the steel bar 120, and an outer peripheral portion that has a helical shape with a larger radius than the inner peripheral portion. It is a helical shape having (111a), and in this embodiment, it is supposed to rotate once (rotate 360 degrees) (however, it does not necessarily have to rotate once (rotate 360 degrees)).

In addition, the middle plate coil piece 112 also has an inner peripheral portion 112b that has a helical shape with a relatively small radius and an inner diameter that is approximately close to the outer diameter of the steel bar 120, and an outer peripheral portion that has a helical shape with a larger radius than the inner peripheral portion. It is a helical shape having (112a), and in this embodiment, it is supposed to rotate once (rotate 360 degrees) (however, it does not necessarily have to rotate once (rotate 360 degrees)).

Likewise, the rear plate coil piece 113 also has an inner peripheral portion 113b that has a helical shape with a relatively small radius and an inner diameter that is approximately close to the outer diameter of the steel bar 120, and an outer peripheral portion that has a helical shape with a larger radius than the inner peripheral portion. It is a helical shape having (113a), and in this embodiment, it is supposed to rotate once (rotate 360 degrees) (however, it does not necessarily have to rotate once (rotate 360 degrees)).

Therefore, when storing or carrying, as shown in Figure 10, each plate coil piece is stored overlapping with another, and there is no need to forcibly fold or unfold it as in the third prior art. Therefore, the third prior art Since it can be made of a more rigid material than plate coil, such as stainless steel, it can be manufactured regardless of material or elasticity, and it is easy to handle because there is no need to forcibly fold or unfold it.

Conversely, when using the plate coil of the present invention, as shown in FIG. 9A, a plurality of plate coil pieces must be connected and coupled to a steel bar, so the following three configurations must be added.

i) Since the plate coil 110 and the steel rod 120 are constructed separately, the plate coil 110 and the steel rod 120 must be rotated as one unit without spinning. In other words, 'means to prevent slipping' must be provided.

ii) When in use, each plate coil piece must be able to hold its position in the axial direction (in the longitudinal direction of the steel bar) without being pushed. In other words, 'means to prevent axial slipping' must be provided.

iii) Each plate coil piece must be prevented from overlapping in the direction of rotation when rotating. In other words, it is desirable to provide 'rotation direction overlap prevention means'. However, this requirement may be omitted depending on the rigidity or thickness of the plate coil piece, and is not an essential component, but it is more desirable to have it when the plate coil piece has high elasticity and is thin.

And, as such 'means for preventing slipping' and 'means for preventing axial slipping', in this embodiment, the outermost plate coil pieces 111 and 113 and the steel bar 120 are coupled to the rotating shaft using a fixed pin method, and each plate The coil pieces are provided with stoppers (112e, 113e) at the connection points of the plate coil pieces to prevent the plate coils from being pushed in the axial direction.

That is, a pin housing 111c formed by rolling the distal end of the front plate coil piece 111 is formed at the distal end of the front plate coil piece 111 so that a pin seating groove 111d in which the second engagement pin 133b' is seated is formed. As much as possible, it is axially coupled to the coupling tube 133', which is coupled to the steel bar 120, by a coupling means such as a sheet clamp 134'. The coupling with the steel bar through the coupling tube will be described later.

In addition, a stopper 112e is provided at one end of the middle plate coil piece 112 connected to the front plate coil piece 111 by means such as a welding portion 112f, so that the plate coil pieces are sequentially coupled to the steel bar. When doing so, the middle plate coil piece 112 is prevented from being pushed forward (in the longitudinal direction of the steel bar) of the distal end of the front plate coil piece 111.

Likewise, a stopper 113e is provided at one end of the rear plate coil piece 113 connected to the middle plate coil piece 112 by means such as a welding portion 113f, so that the plate coil pieces are sequentially coupled to the steel bar. During the process, the rear plate coil piece 113 is prevented from being pushed forward (in the longitudinal direction of the steel bar) of the distal end of the middle plate coil piece 112, and more preferably, the other end of the rear plate coil piece 113. In order to form a pin seating groove 113d in which the first fastening pin 133b is seated, for example, a pin housing 113c formed by rolling the distal end of a plate coil piece is formed, so that it can be attached to a fastening means such as a sheet clamp 134. It is axially coupled to the coupling tube 133, which is coupled to the steel bar 120,

Now, when the plate coil connection portion 130 used in the plate coil power generation device according to one aspect of the present invention is described with reference to FIGS. 8 to 9b, on one side, the generator 41 of the plate coil power generation device (FIG. 3 In order to perform the function of connecting the plate coil 110 and the steel rod 120 on the other side while being connected to the rotation axis of the reference), the steel rod wire 131 connected to the rotation shaft of the generator ('41' in FIG. 3) and the steel rod A 'L' shaped flange 132 coupled to the wire 131, a first coupling tube 133 coupled to the flange 132, and the first coupling tube 133 connected to the steel bar 120. It includes a first sheet clamp 134 that is pressed to one end of the.

Preferably, a second coupling tube 133' symmetrical to the first coupling tube 133 is provided at the other end of the steel bar 120, and the second coupling tube 133' is connected to the other end of the steel bar 120. It additionally includes a second sheet clamp 134' pressed against the.

Meanwhile, the 'ㄷ' shaped flange 132 has, for example, a first branch 132a and a second branch 132b facing each other in the form of a metal plate with some degree of elasticity, and these are each It is firmly attached to the inner surface of the first coupling tube 133, for example, through a welding portion 139. At this time, the first coupling tube 133 is wrapped around one end of the steel bar 120 (for example, By being compressed with a pressing means (such as the first sheet clamp 134), the steel bar 120 and the connecting portion 130 are coupled.

In this process, the pin housing 111c of the front plate coil piece 111 of the plate coil 110 is previously inserted and fastened to the second connection pin 133b' of the second connection tube 133'. In a state where the second coupling tube 133' is inserted into the front of the steel bar 120 and surrounds the tip of the steel bar 120, a pressing means (such as a second sheet clamp 134') By being compressed, the steel rod 120, the second coupling tube 133', and the front plate coil piece 111 are axially coupled, and then the middle plate coil piece 112 is attached to the steel rod 120 from the rear. As it is inserted, it is coupled to the rear of the front plate coil piece 111, and the fin housing 111c of the rear plate coil piece 111 of the plate coil 110 is connected to the first coupling tube 133 in advance. 1 In the state of being inserted and fastened to the binding pin 133b, the steel rod 120 and the connecting portion 130 are coupled, so that the plate coil 110, the steel rod 120, and the connecting portion 130 are connected to each other. It is combined as one.

Figure 9a is a perspective view of these coupled states. Before coupling, the slit 133a of the coupling tube 133 is slightly opened and inserted into the steel bar 120, but is compressed using a compression means such as the first sheet clamp 134. In the completed state, the slit 133a is adhered so closely that it is barely visible.

An unexplained reference numeral 131a denotes a 'clamping part' for coupling the first flange 132 and the steel bar wire 131.

The method by which the 'ㄷ' shaped flange 132 in this embodiment is coupled to the binding tube 133 is a general welding portion 139, but it may also be coupled by riveting or other methods, and can be configured like this. When this is done, the connection part 130 including the generally long steel bar 120 and the steel bar wire 131 can be separately configured, which has the additional advantage of being more convenient to carry. For reference, when joining the 'ㄷ' shaped flange 132 and the coupling tube 133 by welding, it is preferable that the 'ㄷ' shaped flange 132 be manufactured from a thin metal plate.

Meanwhile, a first pin housing (111c) and a second pin housing (113c) are formed on the front plate coil piece 111 and the rear plate coil piece 113 of the plate coil 110, respectively, as shown in FIGS. 8 and 8 As shown in 9a, first and second coupling pins protrude from one side of the first and second coupling tubes 133 and 133', respectively, which have a slit 133a on one side as a coupling means and form a 'C' shape. (133b, 133b') are inserted into the first and second seating grooves (111d, 113d') of the pin housing, respectively, so that the plate coil 110 is axially coupled to the steel bar 120. .

More specifically, while the first and second coupling pins 133b and 133b' are inserted into the first and second pin housings 111c and 113c, they are slidably inserted into the steel bar 120, Thereafter, the first and second fastening tubes 133, 133' are firmly fastened to an appropriate position on the steel bar 120 using the first and second sheet clamps 134, 134', which are pre-inserted or newly inserted. will be.

That is, the first and second coupling tubes 133, 133' are 'C' shaped with a slit 133a, so they can be slidably inserted when inserted into a steel bar, and when removed, the outer diameter of the coupling tube is slightly larger. The first and second sheet clamps 134 and 134' having an inner diameter pressing portion 134a can also be mounted to surround the first and second coupling tubes 133 and 133', but when fixed after mounting, By turning the handles 134c (see the dotted line in FIG. 8) of the first and second seat clamps 134 and 134' in the direction of the red arrow (see arrow "A" in FIG. 8), the screw portion 134b is After tightening to a certain extent, the handle 134c having an eccentric portion is pressed in the direction of the blue arrow (see arrow “B” in FIG. 8) to completely secure the first seat clamp 134 and the first coupling tube 133. ) is pressed and fixed to the inside of the steel bar 120 (see the solid line portion in FIG. 8), and the handle is pressed in the same manner to completely connect the second sheet clamp 134' and the second coupling tube 133'. It is pressed and fixed to the outside of the steel bar 120.

Meanwhile, the steel bar 120 is axially coupled to the power generation unit (not shown: see '40' in FIG. 3) through the connection part 130. For example, the connection part 130 is axially coupled to the power generation unit. The steel bar wire 131 is coupled to the flange 132 using a clamping part 131a, etc., and the flange 132 is coupled to the coupling tube 133 using a welding part 139, etc., and is again connected to the sheet. It is coupled to the steel bar 120 through a compression means such as a clamp 134.

Therefore, as shown in Figure 9a, in the state where each plate coil piece (111 to 113) of the present invention is inserted into the steel bar (120), the longitudinal direction of the steel bar is moved by the fastening means and the stoppers (112e, 113e) of each plate coil piece. After being aligned and fixed by the connection part 130 of this embodiment, it is mounted in a place where water flow occurs, either natural or artificial, such as a valley, river, or boat, and when the plate coil 110 rotates due to the water flow. , the rotational force is transmitted to the power generation unit through the connection part 130 and ultimately through the steel bar wire 131, thereby generating small hydropower generation. In addition, when not in use, the connection portion 130 is loosened to disassemble each plate coil piece 111 to 113, and then folded to overlap as shown in FIG. 10, making storage and carrying easy.

(Modification of the first embodiment)

Meanwhile, various modifications are possible in the first embodiment of the present invention, which will be described with reference to FIG. 11.

Figure 11 is a modified example of the plate coil power generation device according to the first embodiment of the present invention.

That is, in the case of the plate coil power generation device according to the first embodiment, i) 'means for preventing slipping' and ii) 'means for preventing axial slipping' are provided, but iii) 'means for preventing rotational overlap' are separate. Without it, different rotations of adjacent plate coil pieces were prevented due to the thickness of the contact parts of each plate coil piece. For example, due to differences in water flow, the middle plate coil piece 112 is stationary or rotates clockwise when viewed from the right (rear), while the front plate coil piece 111 rotates clockwise when viewed from the right (rear). In the case of clockwise rotation, the compression function of the stopper 112e may be disabled as adjacent portions of each plate coil plate overlap in the direction of rotation, and in this case, the alignment of each plate coil piece at equal intervals in the axial direction may be disrupted. . The front plate coil piece 111 is in a stationary state or rotates counterclockwise when viewed from the right (rear), while the middle plate coil piece 112 is in a stationary state even when the middle plate coil piece 112 is rotated clockwise. The same problem may occur between the rear plate coil pieces 113 that rotate counterclockwise.

Therefore, in order to definitely prevent this problem, a thick portion or abutting portion (111g, 112g) is provided at the corresponding position where the front plate coil piece 111 and the middle plate coil piece 112 are in contact, and the rear plate coil piece (111g, 112g) is provided. It is desirable to provide a thick portion or abutting portion (113g, 112g') at the corresponding position where 113) and the intermediate plate coil piece 112 come into contact.

For reference, in the case of the plate coil used in the plate coil power generation device according to the first embodiment, it moves as if rotating clockwise when viewed from the right, but this is just an example, and even in the case of moving in the opposite direction, only the rotation direction Since it is different and the rest is the same as the plate coil of the first embodiment, detailed description will be omitted.

On the other hand, when the steel bar wire 131 is used as a twisted wire made by twisting several steel wires rather than a single steel wire, good bending and durability can be improved. In this case, the twisting direction of the twisted wire is in the left-hand thread direction. The rotation direction of the plate coil 110' must also vary depending on whether it is a right-hand screw direction, and the rotation direction of the plate coil 110' is opposite to that of the first embodiment.

(Second embodiment and its modifications)

Hereinafter, the second embodiment of the present invention will be described in more detail with reference to FIGS. 12 and 13 of the attached drawings.

Figure 12 is an exploded perspective view of a plate coil power generation device according to a second embodiment of the present invention, and Figure 13 is an exploded perspective view of a plate coil power generation device according to a modification of the second embodiment of the present invention.

First, as shown in FIG. 14, the biggest feature of the plate coil power generation device of the second embodiment compared to the first embodiment is that each plate coil piece is directly attached to the steel bar using a binding pin.

That is, as shown in FIG. 14, in the plate coil power generation device of the second embodiment, each plate coil piece 111, 112, and 113 is provided with pin seating grooves 111d, 112d, and 113d in the same manner as the pin housings 111c, 112c, and 113c. ), and fill holes (122, 122", 122') are formed at corresponding positions on the steel bar (120), and each plate coil piece is fixed to the steel bar through respective binding pins (140, 140", 140'). By fixing it in position, both i) 'means for preventing slipping' and ii) 'means for preventing axial slippage' are provided without any other parts.

Moreover, according to the plate coil power generation device of this embodiment, iii) 'rotation direction overlap prevention means' can be automatically provided by the binding pin.

At this time, it is better to provide a bolt portion 123 at the rear end of the steel bar 120 so that the plate coil 120 can be more firmly fixed with a separate fixing nut 124. In addition, the steel bar 120 and the generator ('41' in FIG. 3) can also be connected by the same connection part 130 as in the first embodiment, that is, the generator (in FIG. 3). A steel bar wire 131 connected to the rotation axis of '41'), a 'ㄷ' shaped flange 132 coupled to the steel bar wire 131, and a first coupling tube 133 coupled to the flange 132. ) and a first sheet clamp 134 that presses the first coupling tube 133 to one end of the steel bar 120.

The unexplained symbol (121) is a 'cap part' provided at the tip of the steel bar, and (124a) is a 'rotation handle' of the fixing nut.

Preferably, a threaded portion is provided at the tip of the fastening pin, and a nut portion is provided at the corresponding peel hole, so that the fastening can be more firmly achieved by the threaded portion and the nut portion.

Meanwhile, in this embodiment, a pin housing is provided separately for each plate coil piece, but if each plate coil piece has sufficient rigidity, a binding pin is fastened to the steel bar at an appropriate position of the plate coil piece without a pin housing to attach the plate to the plate. The coil piece can also be fixed.

However, in the case of this embodiment, since each plate coil piece is fastened with a binding pin, when the number of plate coil pieces is large (e.g., 7 or more), binding takes a lot of time, so it is not preferable, and only a few pieces are used. In this case (e.g., 4 or less), it is an advantageous method because it can be firmly fixed compared to the first embodiment.

On the other hand, in this second embodiment, various modifications are possible. For example, as shown in FIG. 13, in the case of the connection portion 130' in this modification, the generator ('41' in FIG. 3) A steel bar wire 131 connected to the rotation axis and a nut part 131b screwed to the bolt part 123 of the steel bar are directly formed at the tip of the steel bar wire 131, and these are fixed with a clamping part 131a. It is also possible to directly connect the steel bar 120 and the steel bar wire 131 by bolt fastening.

(Third embodiment and its modifications)

Now, the third embodiment of the present invention and its modification will be described in more detail with reference to FIGS. 14 and 15 of the attached drawings.

Figure 14 is an exploded perspective view of the plate coil power generation device according to the third embodiment of the present invention, and Figure 15 is a cross-sectional view of the plate coil power generation device according to modified examples of the third embodiment of the present invention, (a) of Figure 15 is a first modification of the third embodiment, Figure 15(b) is a second modification of the third embodiment, and Figure 15(c) is a third modification of the third embodiment.

The plate coil power generation device of the third embodiment is characterized in that the cross-section of the steel bar 120 is asymmetric, so that i) 'means for preventing idle rotation' are automatically achieved.

That is, as shown in FIG. 14, a key 125 is formed integrally with one side of the steel bar 120 in the axial direction, and a key groove ( 111h, 112h, 113h) respectively. Therefore, when any one of the plate coil pieces 111, 112, and 113 rotates, the entire steel bar 120 rotates.

Meanwhile, in this third embodiment, ii) 'axial slip prevention means' must be separately provided, and as in the first embodiment, a stopper (112e) is installed at the boundary of one side of the adjacent plate coil piece. , 113e) is provided by means such as welding portions 112f and 113f, and a cap portion 121 is formed at the very tip of the steel rod 120, and a threaded portion 123 is formed at the rearmost end of the steel rod 120. By doing so, axial pushing is prevented by the fixing nut 124.

According to this third embodiment, the pin housing 111c of the first and second embodiments is not required, making it possible to manufacture a simpler plate coil piece.

Moreover, according to the plate coil power generation device of the third embodiment, iii) 'rotation direction overlap prevention means' can be automatically provided by the key and key groove.

On the other hand, in this third embodiment as well, various modifications are possible as shown in FIG. 15.

You can also manufacture it.

In the case of the second and third modifications of the present third embodiment, manufacturing of the steel bar may be somewhat difficult compared to other embodiments, but there is no need for fastening pins or other fastening means, and the object of the present invention can be achieved with the simplest configuration. can be achieved.

Although the present invention has been described above according to an embodiment of the present invention, changes and modifications made by those skilled in the art without departing from the technical spirit of the present invention do not fall within the scope of the present invention. Of course.

(Second First Embodiment)

Hereinafter, the second first embodiment of the present invention will be described in more detail with reference to FIGS. 16 to 32 of the attached drawings.

Figures 16 and 17 are perspective views of the assembled state of the plate coil power generation device according to the second first and second embodiments of the present invention, and Figure 18 is a plate coil of the plate coil power generation device according to the second first and second embodiments of the present invention. It is an assembly diagram of the turbine part in an assembled state, and Figure 19 is an assembly diagram of the plate coil turbine part of the plate coil power generation device according to the second second embodiment of the present invention. Figure 26 is a part diagram of the generator part of the plate coil power generation device according to the first and second second embodiments of the present invention. Figures 31 and 32 are plate coil state diagrams of the plate coil power generation device according to the first and second second embodiments of the present invention.

First, the plate coil 211 used in the plate coil power generation device according to the second first and second embodiments of the present invention, as shown in FIGS. 18 and 19, is generally a square tube of the square tube 213. (213) A plate coil having an inner edge forming a helical shape with a relatively small inner surface close to the outer surface and an outer peripheral edge forming a helical shape with a radius larger than the inner edge, which is different from the third prior art. The point is that it is separated into a plurality of plate coil pieces. In this embodiment, it is made up of five plate coil pieces that rotate once (360 degrees), but the number does not necessarily have to be five, and one plate coil piece does not necessarily have to rotate once (360 degrees).

Therefore, when storing or carrying, as shown in Figure 28, each plate coil piece is stored overlapping each other, and there is no need to forcibly fold or unfold it as in the third prior art. Therefore, the third prior art Since it can be made of a more rigid material than plate coil, such as stainless steel, it can be manufactured regardless of material or elasticity, and it is easy to handle because there is no need to forcibly fold or unfold it.

Conversely, when using the plate coil of the present invention, as shown in FIGS. 18 and 19, a plurality of plate coil pieces must be connected and coupled to the square tube 213, so the following three configurations must be added.

i) Since the plate coil 211 and the square tube 213 are constructed separately, the plate coil 211 and the square tube 213 must be rotated as one unit without spinning. In other words, 'means to prevent slipping' must be provided.

ii) When in use, each plate coil piece must be able to hold its position in the axial direction (in the longitudinal direction of the square tube 213) without being pushed. In other words, 'means to prevent axial slipping' must be provided.

iii) Each plate coil piece must be prevented from turning in the direction of rotation when rotating. In other words, it is desirable to provide 'rotation direction overlap prevention means'. However, this requirement may be omitted depending on the rigidity or thickness of the plate coil piece, and is not an essential component, but it is more desirable to have it when the plate coil piece has high elasticity and is thin.

And, as such 'means for preventing slipping' and 'means for preventing axial slipping', in this embodiment, the plate coil 211 is coupled to the rotation axis with a square groove between the plate coil 211 and the square tube 213. , Each plate coil piece is overlapped to prevent the plate coil from being pushed in the axial direction at the connection point of the plate coil pieces.

The method of manufacturing the plate coil 211 is to cut the steel plate into a circular shape on the outer circumference with a laser as shown in Figures 29 and 30, but cut the center into a square shape to be assembled with the square tube 213. At this time, as shown in Figures 18 and 19, the center is cut into a square shape so that the overlap angle θ (219) can be obtained, but the center of the No. 1 laser cut disc (215) is a vertical center part of a square shape, and there is only one outer circle. Make an incision. Next, the second laser cut disk 216 is cut at a θ angle from the vertical center of the square shape to the outer circle. Next, the No. 3 laser cut disk 217 is cut at a 2θ angle from the vertical center of the square shape to the outer circle in the center. Next, the 4th laser cutting disc 218 is cut at a 3θ angle from the vertical center part of the square shape to the outer circular shape in the center. In the example of the present invention, a square shape is shown at the center of the plate coil 211, but the shape of the center of the plate coil 211 can be any angular shape or a shape that prevents rotation, except for a circle. For example, there are various shapes such as rectangle, oval, triangle, trapezoid, gear shape, serration shape, etc. This is possible if an axis of the same shape is provided by placing these shapes at the center, and the present invention allows some blade parts of the plate coils 211 to overlap at θ angles and prevent axial pushing, so that the rotational force of the various plate coils 211 is reduced to an axis. It is to be delivered to . Therefore, some blades of the plate coil 211 overlap at a θ angle, so it can be easily used, and the blades of the plate coil 211 can be folded and stored as shown in Figure 28, which is easy, simple, and convenient, and this is the main advantage of the invention. . Additionally, the θ angle of some blades of the plate coil 211 can be of any size, and the size of the angle is not required to be constant. Steel plates cut with a laser in this way (here, stainless steel plates, etc. can be used, but are not limited to steel plates, and other materials are also possible) have downward banding (253) and upward banding (253) as shown in Figures 31 and 32. 254), it can be manufactured into the shape shown in Figure 27 by bending it as shown in Figure 27. Figures 31 and 32 are views of the plate coil 211 from above, that is, from the direction of the generator. The plate coils 211, each banded 253 and 254 at various θ angles, can be assembled to overlap a square tube as shown in FIG. 18. Of course, square bars are also possible. Figure 18 shows the second first embodiment, in which the blades of the plate coil 211 are overlapped and a square pipe, that is, a square pipe 213, can be inserted. After inserting it in this way, if the water flows from the top to the bottom as seen in the drawing, the No. 1 laser cutting disc (215) is draped over the No. 2 laser cutting disc (216) at an angle θ, and the water presses on the No. 1 laser cutting disc (215). A portion of the force is partially applied to the No. 1 laser cut disk 215, which partially hangs over the No. 2 laser cut disk 216 at an angle θ and presses it so that it is stably fixed. In this process, in the same way, the No. 2 laser cutting disk 216 is draped at a θ angle to press a part of the No. 3 laser cutting disk 217, and in turn, the No. 3 laser cutting disk 217 is draped at a θ angle to perform laser cutting No. 4. A part of the original plate 218 is pressed, and the No. 4 laser cut original plate 218 is draped at a θ angle and is fixed by pressing the No. 1 laser cut original plate 215 above again. The No. 1 laser cut disk 215 at the top has the same shape as the No. 1 laser cut disk 215 rotated 90° and inserted. In this way, the part of the steel plate below each corner presses the part of the steel plate above each corner, so that the No. 1 laser cut disk 215 spanned by the upper pin 210b is stably applied with a downward tensile force and is fixed and stable. The downward tensile force of the various plate coils 211 stretches the outside of the square pipe 213 downwards of the plate coil 211, which has the effect of causing the square pipe groove 212 to shrink and become smaller, thus tightening the square pipe 213. . Therefore, it becomes more secure and stable. In particular, the plate coil 211 can be thin and light, so it is advantageous for portability. In this state, when the plate coils 211 are rotated by the force of the water flowing in an inclined downward direction, the square tube 213 gains rotational force and rotates.

Here, the plate coils 211 can be manufactured using metal molds or can also be manufactured from other materials such as plastic.

The square tube 213 may also have a screw end as shown in FIG. 20. It can also be connected to other pins or other connections.

One or more connection pipes 232 of FIG. 23 may be connected between the square pipe 213 and the generator shaft connection pipe 231 of FIG. 24. One or more wires 244 of FIG. 24 may be connected between the square tube 213 and the generator shaft connection pipe 231 of FIG. 24. The generator shaft connection pipe 231 is connected to the generator shaft screw 225 of the generator shaft 224 of the generator body 221. A generator bracket (223) is coupled to the generator body (221), and there are bracket holes (227) on both sides of the generator bracket (223). The entire generator is pulled through these holes on both sides with a string (241) as shown in Figure 16. It can be fixed and hung on surrounding trees or other buried objects in the assembled state as shown in Figure 17 or in the state of Figure 16. In this way, the large rotational torque generated by power generation, that is, the rotational force, is fixed to the bracket holes 227 on both sides with a string 241 as shown in FIG. It is possible to maintain the entire generator and plate coils 211 pulled by hydraulic power. When electricity is produced in the generator by rotation of the generator shaft 224 of the generator body 221, it is transmitted to the power generation power line 222 as shown in FIGS. 16 and 17. The power generation power line 222 is supported by a string 241 and connected to the outside.

(Second Second Example)

The second second embodiment is similar to the second first embodiment, but as shown in FIG. 19, the No. 1 laser cut disk 215 is placed in the square tube 213 across the square tube jaw 214, and the No. 2 laser cut disk is placed on it. By inserting the laser cutting disk (216), inserting the No. 3 laser cutting disk (217) on top of it, inserting the No. 4 laser cutting disk (218) on top of it, inserting the No. 1 laser cutting disk (215) on top of it, and inserting the pin (210b). Fix it. Then, a part of each disk presses a part of the disk below at an angle θ, so the plate coils 211 are fixed, and the strong plate coils 211 are not bent or pressed and do not deform, so they are stably fixed to the square tube 212. Then, when the plate coils 211 are rotated by the power of water, the square tube 213 is rotated, and the rest are sequentially connected to rotate the generator to produce electricity, the same as the second first embodiment.

17, if the support is not available, the support 242 can be erected and fixed with a string 241 and a stake 243.

The string 241 can be of various types and wire can also be used.

As shown in Figure 33, the generator body 221 is raised to the top of the flowing water, and a string 241 is tied to both ends of the generator bracket hole 227 of the generator bracket 223 and tied to the outer wood or stone with strong tensile force. A bearing that secures the bearing 271 by placing a connection pipe 232, which fixes the bearing 271 to the lower part of the generator body 221, between the square tube 213 and the generator body 221 in the same manner. A string 241 is tied to both ends of the bearing fixing hole 274 of the bracket 273 and fixed to the outside tree or stone with strong tensile force, so that the plate coils 211 of the square pipe 213 are strongly flowing. It is supported so that the plate coils 211 of the square tube 213 can rotate. When the string 241 is strongly fixed to both ends of the bearing fixing hole 274 of the bearing bracket 273 that fixes the bearing 271, the flowing water flows through the plate coils 211 of the square tube 213 in the direction in which the water flows. The strings 241 on both ends of the bracket hole 227 of the generator body 221 on the top of the bearing 271 spaced at a certain distance or millimeter are strongly supported with a force in the opposite direction, so that it is firmly supported. In addition, a weight force is applied in the bottom direction due to the load of the generator body 221, the plate coil 211, the bearing 271, and the plate coil 211 of the square tube 213, so that the hanging power generation devices are kept stable.

If there is no suitable support such as wood or stone on the outer shell as shown in Figure 33, it can be firmly supported with supports 242 and stakes 243 as shown in Figure 34.

It is an integrated set consisting of the generator body (221), the plate coil (211) of the square tube (213), the connecting pipe (232), and the bearings (271), and the set is placed one or more pieces side by side on the string (241). It can develop a lot and develop a lot at the same time.

The present invention has been described based on the right-hand thread direction, but it can also be manufactured and used in the left-hand thread direction.

The advantage of the present invention is that all the parts can be placed in a bag, etc., making it particularly easy to move, install and carry.

By making it slightly larger in size, it is possible to dock ships or ships for portable or mobile use, and by installing several units to generate power, large unit power generation is possible, making it particularly useful for use in renewable energy tidal power generation.

Power generation from valley water near houses can be continuously generated 24 hours a day without damaging nature or the environment. By developing it as a portable device, it can be used as a generator for rapids in narrow streams, waterfalls in valleys, etc., generating several hundred watts for outdoor tents. It is suitable for use as a small-scale generator.

Although the present invention has been described above according to an embodiment of the present invention, changes and modifications made by those skilled in the art without departing from the technical spirit of the present invention do not fall within the scope of the present invention. Of course.
