Description

Fluid power generation equipment and installation structure of power generation equipment

The present invention relates to a fluid power generation device and an installation structure of a power generation device capable of efficiently converting fluid energy such as hydraulic power into electric energy to improve power generation efficiency.

In recent years, in addition to the depletion of fossil fuels, global environmental problems such as global warming have become more serious, so power generation devices and power generation methods that use natural energy are drawing attention. In particular, it is expected that its importance will increase further in the future due to the issue of CO2 emission credits and the introduction of the RPS (Renewable Portfolio Standard) system.

For example, a photovoltaic power generation device that uses sunlight, which is a natural energy source, is easy to install and has a relatively low power generation cost. The spread of large-scale equipment is progressing rapidly.

In addition to the conventional fixed-type photovoltaic power generation device, a portable photovoltaic power generation device that does not require installation work and can be easily transported or changed in the installation location is also attracting attention. For example, Patent Document 1 discloses a portable photovoltaic power generation device that can be installed and used in an arbitrary place such as outdoors without a power source.

Specifically, a large number of electrically connected sheet-shaped or film-shaped photovoltaic power generation sheets can be carried in a stretchable state in the storage case, and the user can carry it from the storage case at any place. By pulling out the photovoltaic power generation sheet, it is possible to use electrical equipment by efficiently using sunlight to generate electricity even outdoors without a power source.

In addition, many fluid drive devices have been proposed in which a generator is generated by driving the drive device using a fluid such as wind power or hydraulic power as a working body. For example, Patent Document 2 discloses a hydroelectric power generation device that is installed in a waterway such as a river or an agricultural waterway and uses water as a natural energy source.

Specifically, it is provided with a main body consisting of two discs arranged facing each other and paddles attached at equal intervals radially from the central axis of the discs, and the paddles in the water receive water flow pressure. As a result, the power generation device is driven by using the rotational force obtained from the water shaft to which the paddle portion is connected.

However, in the photovoltaic power generation device disclosed in Patent Document 1 described above, the amount of power generation depends on the weather and the amount of solar radiation, and is stable only in a time zone in which the amount of solar radiation in the daytime on a sunny day is relatively large. There is a problem that it cannot generate electricity.

On the other hand, in rivers, agricultural canals, etc. where the hydroelectric power generation device disclosed in Patent Document 2 is installed, the amount of water is adjusted so as to maintain a predetermined flow rate every season, so that a constant flow rate is continuously maintained. It is possible to secure it. Therefore, unlike a photovoltaic power generation device, the amount of power generation does not become unstable due to external factors such as the amount of solar radiation, and stable power generation is possible throughout the year.

However, the hydroelectric power generator disclosed in Patent Document 2 has a large diameter of about 1.4 m at the maximum, and when installed in a river with a shallow water depth or a river with a slow flow velocity, for example, the paddle portion installs a water turbine. It is suspected that the amount of power generated cannot be obtained as planned because it cannot receive sufficient water pressure to rotate it.

As a result, the first resistance member in the fluid receives the fluid pressure, and the first and second rotating bodies rotate together with the first endless belt. At this time, even if the plurality of auxiliary rotating bodies are arranged at the same horizontal positions as the first and second rotating bodies, the first and second rotating bodies rotate without any trouble.
Here, when the first endless belt is loosened or displaced, the predetermined auxiliary rotating body can be appropriately moved upward to maintain the tension of the first endless belt. As a result, not only can the first endless belt be prevented from loosening and slipping, but also the first resistance member can be stabilized.
Further, by moving one of the plurality of auxiliary rotating bodies into the fluid and bending the endless belt portion on the fluid surface side into a triangular shape, the length of the endless belt portion in the fluid can be increased.

(Example 1)
FIG. 1 is a perspective view showing a fluid power generation device according to a first embodiment of the present invention, FIG. 2 is a plan view of the fluid power generation device, and FIG. 3 is a cross-sectional view taken along the line AA of FIG. Is.
As shown in FIG. 1, the fluid power generator 1A of this embodiment includes a first rotating body 2A, a second rotating body 2B, a first endless belt 3A, a plurality of first resistance members 30, and a fourth. It includes a rotating body 4, a third rotating body 5, a second endless belt 3B, and a generator 6, and these members are assembled to the support 10.

Specifically, in the support 10, columns 11A and 12A having the same height are arranged side by side in the length direction of the first endless belt 3A. Then, the columns 12B and 12C having the same height as the columns 12A are arranged side by side in the width direction of the first endless belt 3A so as to face the columns 12A, and the columns 11B and 11C higher than the columns 11A face the columns 11A. The first endless belts 3A are arranged side by side in the width direction.

The first rotating body 2A has a shaft portion 20 as a rotation center axis, and both ends of the shaft portion 20 are rotatably attached to columns 11A and 11B.
The second rotating body 2B has the same shape as the first rotating body 2A, and has a shaft portion 21 as a rotation center axis like the first rotating body 2A. Both ends of the shaft portion 21 are rotatably attached to the columns 12A, 12B, and 12C.
That is, the first rotating body 2A and the second rotating body 2B maintain a constant distance in a state where the shaft portions 20 and 21 are parallel to each other, and the first endless belt 3A has such a first endless belt 3A. It is wound around the rotating body 2A and the second rotating body 2B.
The first endless belt 3A is a wide strip-shaped body, and can be formed of a multi-layered rubber member, synthetic resin, metal chain belt, or the like.

The plurality of first resistance members 30 are erected on the surface of the first endless belt 3A.
FIG. 4 is a perspective view showing the first resistance member, and FIG. 5 is a cross-sectional view taken along the line BB of FIG.
As shown in these figures, each of the first resistance members 30 is composed of a pressure receiving surface portion 31 and a support member 32 holding the pressure receiving surface portion 31.
The pressure receiving surface portion 31 is a portion for receiving fluid pressure, and is recessed in an arc shape in cross section. The length of the pressure receiving surface portion 31 is set to be substantially equal to the width of the first endless belt 3A. The material of the pressure receiving surface portion 31 is arbitrary, but in this embodiment, a concavely curved metal plate is applied.
The support member 32 has a frame portion 32a and fixing portions 32b, 32b formed at both ends of the frame portion 32a. The frame portion 32a is arranged along the width direction of the first endless belt 3A, and the fixing portions 32b and 32b are fixed to the first endless belt 3A by screws or the like.
Then, the pressure receiving surface portion 31 is fitted in the frame portion 32a, and the upper end 31a and the lower end 31b thereof are fixed to the frame portion 32a.
That is, with the concave pressure receiving surface portion 31 facing in the length direction of the first endless belt 3A, a plurality of first resistance members 30 are erected on the surface of the first endless belt 3A at regular intervals. There is.

As shown in FIGS. 1 to 3, the fourth rotating body 4 is arranged between the columns 12B and 12C of the support 10, and is attached to the shaft portion 21 of the second rotating body 2B. That is, the fourth rotating body 4 is assembled so as to rotate integrally with the second rotating body 2B.
The diameter of the fourth rotating body 4 is set to be larger than the diameter of the second rotating body 2B. Specifically, the fourth rotating body 4 is a flywheel, and its moment of inertia is set to be substantially twice the moment of inertia of the second rotating body 2B.

The third rotating body 5 is rotatably attached between the columns 11B and 11C, and its shaft portion 53 is connected to the input shaft of the generator 6.
Then, the second endless belt 3B is wound around the third rotating body 5 and the fourth rotating body 4, whereby the rotation of the fourth rotating body 4 becomes the second endless belt 3B. It can be transmitted to the generator 6 through the third rotating body 5.

Next, the operation shown by the fluid power generation device 1A of this embodiment will be described.
FIG. 6 is a schematic diagram for explaining the operation shown by the fluid power generator.
As shown in FIG. 6, the lower portion of the first endless belt 3A of the fluid power generator 1A is slightly below the water surface S, and the concave pressure receiving of the first resistance member 30 in the water W. The support 10 is submerged in water W and fixed so that the surface portion 31 faces the upstream side.
Then, the pressure receiving surface portions 31 of the plurality of first resistance members 30 in the underwater W receive the flowing water pressure and receive the force to the downstream side. As a result, the first resistance member 30 of the underwater W moves to the downstream side, and the entire first endless belt 3A starts to move as indicated by the arrow. As a result, the moving force of the first endless belt 3A is transmitted to the first rotating body 2A and the second rotating body 2B, and the first rotating body 2A and the second rotating body 2B simultaneously move in the direction of the arrow. Rotate.
Then, as the moving speed of the first endless belt 3A increases, the rotation speeds of the first rotating body 2A and the second rotating body 2B also increase, and they are connected to the shaft portion 21 of the second rotating body 2B. The rotation speed of the fourth rotating body 4 also increases. The rotation of the fourth rotating body 4 is transmitted to the third rotating body 5 through the second endless belt 3B. As a result, the rotation of the third rotating body 5 is transmitted to the input shaft of the generator 6 through the shaft portion 53, and the generator 6 generates power.

By the way, in the fluid power generator 1A of this embodiment, the diameter of the fourth rotating body 4 that rotates integrally with the second rotating body 2B is set to be larger than the diameter of the second rotating body 2B. .. Therefore, the rotational energy of the fourth rotating body 4 is higher than that of the second rotating body 2B by the amount corresponding to the difference in diameter. Then, the rotational energy of the fourth rotating body 4 is transmitted to the third rotating body 5 and input to the generator 6. That is, according to the fluid power generation device 1A of this embodiment, a power generation amount larger than the power generation amount obtained by directly connecting the generator 6 to the shaft portion 21 of the second rotating body 2B is referred to as the fourth rotating body 4. It can be obtained through the third rotating body 5.
Specifically, since the moment of inertia of the fourth rotating body 4 is set to twice the moment of inertia of the second rotating body 2B, the rotation of the second rotating body 2B causes the fourth rotating body to rotate. 4 generates a rotational energy that is twice the rotational energy of the second rotating body 2B. Therefore, twice the rotational energy of the second rotating body 2B is input to the generator 6 through the third rotating body 5, and the generator 6 generates a large amount of power.
Further, since the fourth rotating body 4 is a heavy flywheel, the rotation of the second rotating body 2B is stabilized, and the rotational energy of the fourth rotating body 4 is transferred to the third rotating body 5. It can be transmitted stably.

In this embodiment, an example in which the length of the pressure receiving surface portion 31 is set to be substantially equal to the width of the first endless belt 3A has been described, but the length of the pressure receiving surface portion 31 is set to the width of the first endless belt 3A. It may be set slightly shorter than. With such a setting, it is possible to prevent a situation in which the first endless belt 3A comes off from the first and second rotating bodies 2A and 2B, and to obtain stable rotation of the first endless belt 3A.

Specifically, the circumferential surface 4a of the fourth rotating body 4 is set wide, and the plurality of second resistance members 40 stand on the surface adjacent to the surface on which the second endless belt 3B is wound. It is installed. Each of the second resistance members 40 is a flat plate-shaped member, and both sides thereof function as pressure receiving surface portions for receiving fluid pressure.

Since the fluid power generation device 1B of this embodiment has such a configuration, when the fluid power generation device 1B is installed in water as shown in FIG. 8, not only a plurality of first resistance members 30 but also a plurality of first resistance members 30 are installed. The second resistance member 40 of the above is also subjected to running water pressure. As a result, the fourth rotating body 4 can obtain not only the rotational force due to the second rotating body 2B but also the rotational force due to the fluid pressure through the second resistance member 40. That is, the rotational energy of the fourth rotating body 4 increases by the amount of the rotational energy due to the rotational force due to the fluid pressure through the second resistance member 40, and the amount of power generated by the generator 6 also increases.
Since other configurations, actions, and effects are the same as those in the first embodiment, the description thereof will be omitted.

Alternatively, the two fifth rotating bodies 4A can be either one end 21a of the shaft portion 21 of the second rotating body 2B, one end 20a of the shaft portion 20 of the first rotating body 2A, or the other end 20b. Or they may be connected to each of the two. Further, as shown in FIG. 10, the three fifth rotating bodies 4A are divided into one end 21a of the shaft portion 21 of the second rotating body 2B and one end 20a of the shaft portion 20 of the first rotating body 2A. , The other end 20b may be connected to each other.
Since other configurations, actions and effects are the same as those in the first and second embodiments, the description thereof will be omitted.

In the fluid power generation device 1E of this embodiment, the structure of the first resistance member 30 is different from that of the first to third embodiments.

As shown in FIG. 11, the first resistance member 30 applied to this embodiment is composed of a pressure receiving surface portion 31A formed of a flexible material and a support member 32 supporting the pressure receiving surface portion 31A. ..
The pressure receiving surface portion 31A may be made of a flexible material, and the type thereof may be arbitrary, such as cloth, synthetic fiber, or synthetic resin. In this embodiment, a cloth material was applied as the pressure receiving surface portion 31A.
When the flowing water pressure is applied to the pressure receiving surface portion 31A indicated by the solid line from the direction of the arrow indicated by the alternate long and short dash line, the pressure receiving surface portion 31A bends as shown by the alternate long and short dash line due to the flowing water pressure and receives the flowing water pressure like a sail of a yacht. Further, when the direction of the running water pressure changes in the direction indicated by the alternate long and short dash line, the pressure receiving surface portion 31A in the alternate long and short dash line state bends in the flowing water pressure direction as shown by the alternate long and short dash line, and the flowing water pressure is like a sail of a yacht. Receive.

Since the first resistance member 30 of the fluid power generator 1E of this embodiment has the above configuration, as shown in FIG. 12A, when the water flow direction is to the right, the first resistance The pressure receiving surface portion 31A of the member 30 receives the flowing water pressure and bends to the right, and the flowing water pressure applied to the first resistance member 30 causes the first rotating body 2A, the second rotating body 2B, and the first endless belt. 3A rotates counterclockwise.
Then, as shown in FIG. 12B, when the water flow direction changes to the left, the pressure receiving surface portion 31A of the first resistance member 30 receives the water flow pressure and bends to the left. As a result, the first rotating body 2A, the second rotating body 2B, and the first endless belt 3A rotate clockwise.
That is, according to the fluid power generation device 1E of this embodiment, when the fluid power generation device 1E is used in a place where the flow changes, it is not necessary to move the entire direction of the fluid power generation device 1E according to the change in the water flow direction. The operation of the fluid power generation device 1E can be continued without considering the water flow direction.
Since other configurations, actions and effects are the same as those in the first to third embodiments, the description thereof will be omitted.

(Example 5)
Next, a fifth embodiment of the present invention will be described.
FIG. 13 is a schematic cross-sectional view showing a main part of the fluid power generation device according to the fifth embodiment of the present invention.
In the fluid power generation device 1F of this embodiment, the mounting structure of the first resistance member 30 is different from that of the first to fourth embodiments.

As shown in FIG. 13, in the fluid power generation device 1F of this embodiment, the plurality of first resistance members 30 stand on the surface of the first endless belt 3A at regular intervals so that they are alternately oriented in opposite directions. It is installed. Specifically, a plurality of first resistance members 30 are alternately arranged so that the pressure receiving surface portion 31 faces in the opposite direction.
As a result, the first resistance member 30 having the pressure receiving surface portion 31 pointing to the left receives the flowing water pressure in the direction indicated by the solid arrow, and the pressure receiving surface portion 31 facing to the right receives the flowing water pressure in the direction indicated by the alternate long and short dash arrow. The first resistance member 30 can receive it.

Since the first resistance member 30 of the fluid power generation device 1F of this embodiment is arranged as described above, the orientation of the entire fluid power generation device 1F can be changed even when the first resistance member 30 is used in a place where the flow changes. The operation can be continued without moving according to the change in the flow direction.
Since other configurations, actions and effects are the same as those in the first to fourth embodiments, the description thereof will be omitted.

(Example 6)
Next, a sixth embodiment of the present invention will be described.
FIG. 14 is a perspective view showing a main part of the fluid power generation device according to the sixth embodiment of the present invention, and FIG. 15 is a schematic cross-sectional view showing the main part.
In the fluid power generation device 1G of this embodiment, the structure of the first resistance member 30'is different from that of the first to fifth embodiments.

As shown in FIG. 14, in the first resistance member 30'of this embodiment, the resistance members 30A and 30B having the same structure as the first resistance member 30 applied in the first embodiment are joined back to back. It has a structure. Specifically, the structure is such that the pressure-receiving surface portion 31 of the resistance member 30A facing to the left in the figure and the pressure-receiving surface portion 31 of the resistance member 30B facing to the right in the figure are joined back to back via an intermediate member 33.

Since the first resistance member 30'of the fluid power generation device 1G of this embodiment has the above-mentioned structure, as shown by the solid line arrow in FIG. 15, the flowing water pressure in the right direction is the first resistance member. It is received by the pressure receiving surface portion 31 of the resistance member 30B of the resistance member 30', and as shown by the alternate long and short dash arrow, the flowing water pressure in the left direction can be received by the pressure receiving surface portion 31 of the resistance member 30A of the first resistance member 30'. ..
As a result, even when the fluid power generator 1G is used in a place where the flow changes, the operation can be continued without moving the direction of the entire fluid power generator 1G in accordance with the change in the water flow direction.

(Modification example 1)
Here, a modified example of the first resistance member 30 applied to the first to third embodiments and the fifth embodiment will be described.
FIG. 16 is a perspective view showing a modified example of the first resistance member 30 applied to the first to third embodiments and the fifth embodiment, and FIG. 17 is an exploded perspective view of the present modified example. FIG. 18 is a side view showing the first resistance member of the present modification with a part broken.
A large water pressure may be applied to the first resistance member depending on the installation location, and it is necessary to pay attention to its durability. In particular, this tendency is remarkable when the first resistance member is made large.
Therefore, in this modified example, as shown in FIG. 16, the structure of the first resistance member 30C is stronger than that of the first resistance member 30 applied to the first to third embodiments and the fifth embodiment. I made it.

As shown in FIG. 17, the support member 32 is composed of a frame portion 32a, a long fixing portion 32b, and four stoppers 34, and the fixing portion 32b is fixed to the first endless belt 3A, and the frame portion 32a Is rotatably attached to the fixed portion 32b. The four stoppers 34 are the edges of the first endless belt 3A and are arranged on both sides of the frame portion 32a.
Specifically, the frame portion 32a has horizontal reinforcing portions 32c in the frame, and legs 32d and 32d at both lower ends of the frame portion 32a.
The fixing portion 32b is arranged so as to face the width direction of the first endless belt 3A, and the rotating shaft 32b1 is rotatably inserted into the fixing portion 32b.
The legs 32d and 32d of the frame portion 32a are fixed to the exposed portions on both sides of the rotating shaft 32b1.
That is, as shown by the arrow in FIG. 18, the frame portion 32a can be rotated left and right about the rotation shaft 32b1 of the fixed portion 32b.
The four stoppers 34 are arranged on both sides of such a frame portion 32a. Each stopper 34 is fixed to the edge of the first endless belt 3A with the opening 34a facing the leg portion 32d side of the frame portion 32a.
The frame portion 32a is provided with four auxiliary leg portions 32e into which the tip portion can be inserted into such a stopper 34. That is, a pair of auxiliary leg portions 32e and 32e are projected in opposite directions on both sides of the frame portion 32a near the joint position 32a1 with the reinforcing portion 32c. Each leg portion 32d is inclined toward the stopper 34 side from the vicinity of the joint position 32a1 with the reinforcing portion 32c, and the tip portion thereof is positioned in the opening 34a of the stopper 34.
As for the length of each auxiliary leg 32e, as shown in FIG. 18, when the frame 32a is perpendicular to the first endless belt 3A, the tip of the auxiliary leg 32e is the first endless belt. The length is set so that it floats upward from 3A by a predetermined height.

On the other hand, the pressure receiving surface portion 31 is joined to the frame portion 32a via the reinforcing portion 32c and the joining portion 32f.
Specifically, three joint portions 32f are projected from the upper portion and the lower portion of the frame portion 32a at predetermined intervals. Each joint portion 32f projects horizontally from the upper portion (lower portion) of the frame portion 32a. Then, the upper part of the back surface of the pressure receiving surface portion 31 is joined to the three joint portions 32f of the upper part of the frame portion 32a, and the lower part of the back surface of the pressure receiving surface portion 31 is joined to the three joint portions 32f of the lower part of the frame portion 32a. The substantially central portion of the back surface of the pressure receiving surface portion 31 is joined to the reinforcing portion 32c of the frame portion 32a.

Next, the operation of the first resistance member 30C will be described.
FIG. 19 is a side view for explaining the operation shown by the first resistance member 30C of the modified example.
As shown in FIG. 19, when the pressure receiving surface portion 31 of the first resistance member 30C receives the water flow in the direction of arrow A, the frame portion 32a of the support member 32 tilts to the downstream side, and the auxiliary leg portion 32e on the downstream side The tip portion enters the stopper 34, the tip portion of the auxiliary leg portion 32e is locked by the stopper 34, and further inclination of the frame portion 32a is prevented. As a result, the water pressure received by the pressure receiving surface portion 31 is transmitted to the stopper 34 through the auxiliary leg portion 32e, and the force F applied to the stopper 34 causes the first endless belt 3A to move in the direction of the force F, so that the first endless belt 3A moves in the direction of the force F. The endless belt 3A will rotate counterclockwise.

By the way, as shown in FIGS. 4 and 5, in the first resistance member 30 applied in the first embodiment or the like, the frame portion 32a of the support member 32 is joined to the fixed portion 32b, so that the pressure is received. When the surface portion 31 receives the water flow, the force due to the water pressure received by the pressure receiving surface portion 31 is concentratedly applied to the fixed portion 32b. Therefore, if it is used for a long period of time, the fixing portion 32b may be damaged or may be peeled off from the first endless belt 3A. In particular, such a problem may occur when the first resistance member 30 is used in water having a high flow velocity or when the first resistance member 30 itself is made large.

On the other hand, in the first resistance member 30C of this modified example, when the pressure receiving surface portion 31 receives water pressure, the frame portion 32a of the support member 32 rotates downstream around the fixed portion 32b, and the auxiliary leg portion 32e Since the structure is such that the stopper 34 abuts against the stopper 34, the force due to the water pressure received by the pressure receiving surface portion 31 is dispersed between the stopper 34 and the fixing portion 32b. As a result, the force applied to the fixing portion 32b is reduced, so that there is almost no possibility that the fixing portion 32b is damaged or peeled off from the first endless belt 3A.
Other configurations, actions and effects are the same as those of the first resistance member 30 of the first to third embodiments and the fifth embodiment, and thus the description thereof will be omitted.

As shown in FIG. 20, the first resistance member 30D of this modification has a structure in which a pressure receiving surface portion 31A formed of a flexible material is attached to a frame portion 32a of the first resistance member 30C of the modification. It has become.
However, the mounting structure of the pressure receiving surface portion 31A to the frame portion 32a is different from that of the first resistance member 30C of the above modification. That is, in the first resistance member 30D of this modification, the frame-shaped pressure receiving surface mounting portion 35 is arranged inside the frame portion 32a and is joined to the frame portion 32a by a plurality of joining portions 32g. Then, the pressure receiving surface portion 31A is attached to the frame-shaped pressure receiving surface mounting portion 35.
Other configurations, actions and effects are the same as those of the first resistance member 30 of the fourth embodiment and the first resistance member 30C of the modification, and thus the description thereof will be omitted.

It is a side view which shows by breaking a part of the 1st resistance member of.
As shown in FIGS. 21 to 23, the first resistance member 30E of this modification has a structure in which the pressure receiving surface portions 31B and 31C are attached to both sides of the frame portion 32a of the first resistance member 30C of the modification. ing.
Specifically, the back surface of the pressure receiving surface portion 31B is joined to a plurality of joint portions 32f and the reinforcing portion 32c on one surface of the frame portion 32a, and the back surface portion 31C is back-to-back with the pressure receiving surface portion 31B. , A plurality of joint portions 32f'protruding on the other surface of the frame portion 32a and the reinforcing portion 32c were joined.
Other configurations, actions and effects are the same as those of the first resistance member 30'of the sixth embodiment and the first resistance member 30C of the modification, and thus the description thereof will be omitted.

(Example 7)
Next, a seventh embodiment of the present invention will be described.
FIG. 24 is a perspective view showing a fluid power generation device according to a seventh embodiment of the present invention.
As shown in FIG. 24, in the fluid power generator 1H of this embodiment, the first rotating body 2A, the second rotating body 2B, the fourth rotating body 4, and the plurality of auxiliary rotating bodies 2C and 2D are supported. It has a structure supported by 10 so as to be movable up and down.

Specifically, the elongated holes 22 and 22 are formed in the columns 11A and 11B of the support 10, respectively, and both ends of the shaft portion 20 of the first rotating body 2A are rotatably formed in the elongated holes 22 and 22, respectively. It is fitted. Then, the knobs 23 and 23 are attached to the respective tip portions of both end portions of the shaft portion 20. The knobs 23 and 23 are members for rotatably positioning the shaft portion 20 of the first rotating body 2A to a predetermined height.
The elongated holes 22 and 22 as described above are also provided in the columns 12A, 12B and 12C, and are also pinched at the tip of the shaft portion 21 of the second rotating body 2B fitted in the elongated holes 22 and 22. 23, 23 are attached.

The auxiliary rotating bodies 2C and 2D are rotating bodies having the same shape as the first and second rotating bodies 2A and 2B, and the first and second rotating bodies are rotated in a state where the shaft portions 25 and 26 as the central axes are parallel to each other. It is juxtaposed between the bodies 2A and 2B and the first endless belt 3A.
Specifically, the elongated holes 24, 24 which are longer than the elongated holes 22, 22 are formed in the columns 13A and 13B of the support 10, respectively, and both ends of the shaft portion 25 of the auxiliary rotating body 2C are elongated holes. It is rotatably fitted in 24 and 24, respectively. Then, the knobs 23 and 23 are attached to both tip portions of the shaft portion 25, respectively. Similarly, the elongated holes 24 and 24 are also provided in the columns 14A and 14B, and the knobs 23 and 23 are also attached to the tip of the shaft portion 21 of the auxiliary rotating body 2D fitted in the elongated holes 24 and 24. Has been done.

Such a fluid power generator 1H is further provided with two pairs of rollers 50A and 50B for maintaining the tension of the second endless belt 3B.
Each roller pair 50A (50B) is composed of rollers 51 and 52, and the rollers 51 and 52 sandwich both sides of the second endless belt 3B.
The roller pairs 50A and 50B are attached to the second endless belt 3B so as to be side by side. Each of these roller pairs 50A and 50B can move horizontally independently.

Next, a usage example of the fluid power generation device of this embodiment will be described.
FIG. 25 is a schematic view showing an installation state of the fluid power generation device of this embodiment.
It should be noted that this installation structure is also a structure that specifically realizes the installation structure of the power generation device according to the twelfth invention.
As shown in FIG. 25, the lower portion of the first endless belt 3A of the fluid power generator 1H is slightly below the water surface S, and the concave pressure receiving of the first resistance member 30 in the water W. The support 10 is submerged in water W and fixed so that the surface portion 31 faces the upstream side.
At this time, the first and second rotating bodies 2A and 2B and the auxiliary rotating bodies 2C and 2D are positioned in a horizontal row by using the knob 23.
In this state, since the plurality of first resistance members 30 located in the lower portion of the first endless belt 3A are completely submerged in the water W, these first resistance members 30 are fluid. Under pressure, the first and second rotating bodies 2B rotate together with the first endless belt 3A without any trouble.
It is possible to continue using the product in this installed state, but if slack or misalignment occurs in the first endless belt 3A, the slack or the like of the first endless belt 3A must be eliminated.

FIG. 26 is a schematic view showing an installation structure in which the first endless belt is prevented from loosening or the like.
When slack or the like occurs in the first endless belt 3A, as shown in FIG. 26, loosen the knobs 23 and 23 of the columns 13A and 13B, and move the auxiliary rotating body 2C along the elongated holes 24 and 24. At the position where the first endless belt 3A is raised and there is no slack, the auxiliary rotating body 2C is picked and positioned at that position by the knobs 23 and 23.
As a result, the tension of the first endless belt 3A can be maintained, and the stable movement of the first resistance member 30 can be ensured.

The fluid power generation device 1H having such an installation structure can obtain a larger rotational force by lowering either the auxiliary rotating body 2C or 2D.
FIG. 27 is a schematic view showing an installation structure for increasing the rotational force of the fluid power generator of this embodiment.
It should be noted that this installation structure is also a structure that specifically realizes the installation structure of the power generation device according to the thirteenth invention.
As shown in FIG. 27, the rotational force of the fluid power generation device 1H can be increased by locating the auxiliary rotating body 2D in the water W.
Specifically, in the installation state shown in FIG. 25, the knobs 23 and 23 of the columns 14A and 14B are loosened, and as shown in FIG. 27, the auxiliary rotating body 2D is placed along the elongated holes 24 and 24 (see FIG. 24). When the portion of the first endless belt 3A in the underwater W is curved in an inverted triangle, the auxiliary rotating body 2D is picked and positioned at that position by 23 and 23.
As a result, the length of the first endless belt 3A in the underwater W becomes longer than when it is in a normal horizontal shape (see FIG. 25). That is, more than usual first resistance members 30 are completely submerged in the water W, and many first resistance members 30 receive fluid pressure, and the rotational force is further increased.

By the way, when the water surface S rises due to flooding or the like, it is necessary to raise the first endless belt 3A or the like according to the degree of rise of the water surface S.
FIG. 28 is a schematic view showing an ascending state of the fluid power generator.
As shown in FIG. 28, when the water surface S rises from the broken line to the position of the solid line, the main member of the fluid power generator 1H is moved ascending, and the lower portion of the first endless belt 3A rises. It needs to be changed to be slightly lower.
Specifically, the knobs 23 of the first rotating body 2A, the second rotating body 2B, the auxiliary rotating bodies 2C, 2D, and the fourth rotating body 4 are loosened, and these members are made into elongated holes 24, 24. When it is raised along (see FIG. 24) and reaches a desired position, the first rotating body 2A, the second rotating body 2B, the auxiliary rotating body 2C, 2D, and the fourth rotating body 4 are picked, respectively. Positioned at that position by 23.

At this time, since the third rotating body 5 and the generator 6 are not moved upward, the second endless belt wound around the third rotating body 5 and the fourth rotating body 4 due to the raising of the main member. There is a risk that 3B will loosen.
However, in this embodiment, since the roller pairs 50A and 50B are provided, by horizontally moving the roller pairs 50A and 50B in the direction away from each other, the second endless belt 3B is pulled in the tensioning direction and there is no slack. ..
That is, the tension of the second endless belt 3B can be kept constant by the rollers 50A and 50B even when the main member is raised.

By the way, as can be seen from the fact that a person cannot run at all just by being immersed in water below the knee, the resistance of water to an object in the water is greater than that of land.
Therefore, if a part or all of the first rotating body 2A and the second rotating body 2B is submerged in water, these rotating bodies may receive a large water resistance and the rotation efficiency may decrease.
Therefore, as shown in FIG. 29, for example, when only the auxiliary rotating body 2D is submerged in the water W, the other first rotating body 2A, the second rotating body 2B, and the like are positioned above the water surface S. Can be considered.
As a result, the plurality of first resistance members 30 in the water W by the auxiliary rotating body 2D receive the resistance of the water and move the first endless belt 3A downstream. The movement of the first endless belt 3A causes the first rotating body 2A and the second rotating body 2B to rotate, enabling power generation. At this time, since the first rotating body 2A and the second rotating body 2B are located above the water surface S, they rotate smoothly without receiving any resistance of water. As a result, the rotational efficiency of the first rotating body 2A and the second rotating body 2B is improved, and the power generation capacity is also increased.
Since other configurations, actions and effects are the same as those in the first to sixth embodiments, the description thereof will be omitted.

(Example 8)
Next, an eighth embodiment of the present invention will be described.
FIG. 30 is a perspective view showing a fluid power generation device according to an eighth embodiment of the present invention.
As shown in FIG. 30, the fluid power generation device 1I of this embodiment is different from the seventh embodiment in that the mounting structure of the first resistance member 30 of the fifth embodiment is applied.

That is, a plurality of first resistance members 30 are erected on the surface of the first endless belt 3A at regular intervals so that they are alternately oriented in opposite directions. Specifically, a plurality of first resistance members 30 are alternately arranged so that the pressure receiving surface portion 31 faces in the opposite direction.

FIG. 31 is a schematic view showing an installation structure of a fluid power generation device for flowing water in the right direction in the figure, and FIG. 32 is a schematic view showing an installation structure of a fluid power generation device for running water in the left direction in the figure.
As shown by the arrow in FIG. 31, when the water flow direction is to the right, the auxiliary rotating body 2D is submerged in the water W so that the left-facing pressure receiving surface portion 31 of the first resistance member 30 can flow water. Under pressure. As a result, the first endless belt 3A and the second endless belt 3B rotate counterclockwise, and the generator 6 starts the power generation operation.
Then, as shown in FIG. 32, when the flowing water direction changes to the left, the auxiliary rotating body 2D can be raised above the water surface S, and the auxiliary rotating body 2C can be submerged in the water W. .. As a result, the right-facing pressure receiving surface portion 31 of the first resistance member 30 receives the flowing water pressure, the first endless belt 3A and the second endless belt 3B rotate clockwise, and the generator 6 generates electricity. Continue operation.
That is, according to the fluid power generation device 1I of this embodiment, it is not necessary to move the entire direction of the fluid power generation device 1I in accordance with the change in the water flow direction even when the fluid power generation device 1I is used in a place where the flow changes.
Since other configurations, actions and effects are the same as those in the fifth and seventh embodiments, the description thereof will be omitted.

(Example 9)
Next, a ninth embodiment of the present invention will be described.
33 is a perspective view showing a fluid power generation device according to a ninth embodiment of the present invention, FIG. 34 is a plan view of the fluid power generation device, and FIG. 35 is a cross-sectional view taken along the line CC of FIG. 34. Is.
As shown in FIG. 33, the fluid power generation device 1J of this embodiment is different from the seventh and eighth embodiments in that the cover body 7 is provided.

The cover body 7 is a frame-shaped body that is open vertically, and as shown in FIG. 34, the first rotating body 2A and the second rotating body 7 are rotated so as not to come into contact with any of the plurality of first resistance members 30. The body 2B, the auxiliary rotating bodies 2C and 2D, the first endless belt 3A, and the plurality of first resistance members 30 are surrounded from the surroundings. Then, in such a state, the cover body 7 is fixed to the support body 10.
Specifically, the cover body 7 is fitted to the outside of the columns 11A to 14A and 11B to 14B of the support body 10. The circular holes (not shown) are the side surfaces of the cover body 7, and both ends of the shaft portion 20 of the first rotating body 2A, both ends of the shaft portion 21 of the second rotating body 2B, and the auxiliary rotating body 2C, It is opened at a position corresponding to both ends of the 2D shaft portions 25 and 26, respectively. Both ends of the shaft portions 20, 21, 25, and 26 are inserted into these circular holes, the knobs 23 are tightened to the respective end portions, and the cover body 7 is fixed to the support body 10.
Further, as shown in FIG. 35, the cover body 7 is set so that the lower edge 7a of the cover body 7 is located near the water surface S. That is, it is a mechanical portion composed of a first rotating body 2A, a second rotating body 2B, auxiliary rotating bodies 2C, 2D, a first endless belt 3A, and a plurality of first resistance members 30, and is a water surface. The mounting position of the cover body 7 is set so as to completely surround the mechanical portion located on the S from the surroundings.

By the way, when the fluid power generation device 1J is used in water in which the flow of water flows in one direction as a whole and does not have a local complicated flow, the cover body 7 is the cover body 7 as described above. It suffices to set the lower edge 7a to be located near the water surface S. However, when this fluid power generator 1J is used in water having a locally complicated flow, the first resistance member 30 and the like cause rolling and the like, and the first endless belt 3A becomes the first and second rotating bodies. It may come off from 2A and 2B.
Therefore, when the fluid power generator 1J is used in such water, the lower edge 7a is lower than the lower end of the first resistance member 30 in the water W, as shown by the alternate long and short dash line in FIG. 35. Set to.
That is, the entire mechanism portion composed of the first rotating body 2A, the second rotating body 2B, the auxiliary rotating bodies 2C, 2D, the first endless belt 3A, and the plurality of first resistance members 30 is seen from the surroundings. By setting the mounting position of the cover body 7 so as to completely surround the cover body 7, the cover body 7 itself becomes slightly larger, but the influence of the above-mentioned local complicated flow can be prevented. As a result, stable rotation and slip prevention of the first endless belt 3A can be achieved.

By adopting the configuration in which the fluid power generator 1J is applied, even if a storm or flooding occurs and a wave wind occurs, the first rotating body 2A, the second rotating body 2B, the auxiliary rotating bodies 2C, 2D and the first endless The cover body 7 protects the mechanical portion composed of the belt 3A and the plurality of first resistance members 30 and located on the water surface S.

In this embodiment, in order to completely prevent water ingress, a circular hole is formed on the side surface of the cover body 7, and both ends of the shaft portion 20 and the like of the first rotating body 2A are inserted into the circular hole, and the knob 23 is inserted. The configuration to be fixed by is illustrated.
However, instead of the circular hole, a long hole having the same shape as the long holes 22 and 24 (see FIG. 33) formed in the support columns 11A and 13A is provided at the side surface position of the cover body 7 corresponding to the long holes 22 and 24. By opening the cover body 7, the cover body 7 can be attached to the support body 10 so as to be movable up and down. In this case, although some inundation is unavoidable, the cover body 7 itself and the auxiliary rotating bodies 2C, 2D and the like can be moved up and down without removing the cover body 7 from the support body 10, which is very convenient.
Since other configurations, actions and effects are the same as those in the 7th and 8th examples, the description thereof will be omitted.

(Example 10)
Next, a tenth embodiment of the present invention will be described.
FIG. 36 is a cross-sectional view showing a fluid power generation device according to a tenth embodiment of the present invention.
As shown in FIG. 36, the fluid power generation device 1K of this embodiment is different from the ninth embodiment in that the cover body 7 has an upper surface portion 70.
Specifically, a dome-shaped upper surface portion 70 was formed on the upper edge 7b of the cover body 7. As a result, the upper opening of the cover body 7 is completely closed by the upper surface portion 70, so that the mechanical portion of the fluid power generator 1K is completely covered by the cover body 7 from the surroundings and above, and is completely protected from the wave wind. Will be done.
Since other configurations, actions, and effects are the same as those in the ninth embodiment, the description thereof will be omitted.

The present invention is not limited to the above embodiment, and various modifications and changes can be made within the scope of the gist of the invention.
For example, in the above embodiment, the power generation devices 1A to 1K using water are exemplified as the fluid power generation device, but the fluid power generation device is not limited to the one using water. For example, it can be installed in the atmosphere and applied as a wind power generator that converts energy obtained from wind pressure into electrical energy.
Further, in the first resistance member 30C of the first modification, as shown in FIG. 18, a pair of auxiliary legs 32e and 32e are projected on both sides of the frame 32a in the opposite directions, and these auxiliary legs are projected. The structure is such that a pair of stoppers 34, 34 into which the portions 32e, 32e can enter are arranged at the edge of the first endless belt 3A, and the structure of the first resistance member 30C is shown in FIG. 37. As described above, the structure may be such that only the auxiliary leg portion 32e and the stopper 34 located on the downstream side are provided, and the auxiliary leg portion 32e and the stopper 34 located on the upstream side are excluded. The same applies to the first resistance member 30D of the second modification.
