Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a generator which receives a force when a fluid such as wind or water (for example, an ocean current or a tide) flows through a plurality of blades and rotates a rotating body having these blades. It relates to a rotary power generation device that generates power by
In particular, it relates to improvement of the power generation efficiency.

[0002]

2. Description of the Related Art Conventional rotary power generators include a vertical rotary type in which a rotary body has a horizontal axis and rotates in a vertical direction by receiving a force caused by a flow of a fluid from the rotary axis direction of the rotary body. 2. Description of the Related Art A horizontal rotation type having an axis and rotating in a horizontal direction by receiving a force of a fluid flow from a direction perpendicular to a rotation axis of a rotating body is generally well known. The vertical rotation type has a propeller-shaped rotating body composed of a plurality of blades, and faces the blades in the direction in which the fluid flows according to the direction in which the fluid flows (turns the blades in the upstream direction of the fluid). Thus, the rotating body rotates and drives the generator connected to the rotating body. The horizontal rotating type includes a plurality of curved or planar plate blades or spiral band-shaped blades, and a rotating body having a substantially cylindrical appearance applies a force due to fluid flow from all horizontal directions to the blades. In this case, the electric power generator rotates in a horizontal direction upon receiving the electric power, and generates electric power by a generator connected to a rotating body, and a so-called Savonius type is generally known.

[0003] The above-described rotary power generation device is generally used as a device for generating power using the power (energy) of a fluid such as wind or water (for example, an ocean current or a tidal current). It is generally known that the energy obtained from a fluid is approximately proportional to the cube of the flow velocity and proportional to the area receiving the force of the fluid. In particular, in the case of wind power, the fluctuation range of the wind speed is large, and strong energy can be obtained in a strong wind, but sparse energy is obtained in a weak wind. On average, wind energy is an energy source with low energy density and difficult to use, because strong winds rarely blow in general areas. Therefore, regarding the use of wind power, the installation location is limited to areas where the average wind speed is high, each part is made of a material or structure that does not break even in strong winds, the wind receiving area is increased, and the rotation efficiency of the blades and rotating bodies is increased. It is necessary to convert wind energy into electrical energy as efficiently as possible, and to reduce the construction cost of the entire equipment.

Prior art 1. Japanese Patent Application Laid-Open No. 9-60573 "Wind power generator" describes an improved example of the above-mentioned horizontal rotary power generator which rotates by wind power. That is,
An opening is provided in the plate-like blade, and a shutter is attached to the opening. The shutter closes the opening when the blade rotates in the leeward direction, and opens when the blade rotates in the leeward direction. A technique has been proposed as a technique that can prevent a rotation torque from being destroyed by wind force received when a blade rotates in a windward direction, and can efficiently rotate a windmill (rotary body) to which the blade is attached. In addition, by limiting to the wind power generator described above, a shock absorbing material made of an elastic material such as a spring or rubber is attached to the blade or the shutter, and the shock when the shutter closes the opening of the blade is absorbed.
Measures have been proposed to prevent noise when the shutter closes. In addition, a method of efficiently rotating a windmill on which the blades are attached, such as by bending the tip of the blade in a direction opposite to the rotation direction of the blade or by curving the entire blade in a concave shape, limited to the wind power generator. Has been presented.

Prior art 2. In Japanese Patent Application Laid-Open No. 2000-97145, "wind power generator", a vertically rotating wind power generator using a propeller is mounted on a support fixed to the ground or the like, and the wind power generator is manually operated along the support using wires and pulleys. Or it can be moved up and down by electric power, and by using the change characteristic of the wind speed that increases exponentially in proportion to the height from the ground, while controlling the rotation speed of the propeller by raising and lowering the wind power generator, There has been proposed a method of preventing the propeller from rotating at an excessive number of revolutions or being damaged by lowering the propeller downward in a strong wind.

Prior art 3. Japanese Unexamined Patent Publication No. Hei 11-343959 "wind power generator" describes the shape of a blade in a wind power generator using the Savonius type wind turbine. Further, regarding the material of the blade, a steel plate may be used or a core material may be used. Compared to the conventional material, such as using steel for reinforcement and using fiber reinforced plastic (FRP) for the outer skin, the cross section is made hollow with a plate material such as a hard metal plate and the inside of the hollow is filled with foam resin. Thus, a technique for increasing the strength and reducing the weight of the blade has been proposed. By reducing the weight of the blade, highly efficient rotation of the blade or the rotating body can be expected.

Conventional technique 4. In Japanese Patent Application Laid-Open No. 7-158554, "a shelf with a wind turbine for wind power generation installed", a large number of wind turbines of a vertical rotation type wind power generator are intensively installed on a shelf with a large amount of power generation. According to the company, it is possible to reduce the weight and cost of pillars that support wind turbines.

Prior art 5. JP 2000-102294A
In the gazette of “Small and medium-sized wind power generator”, the output from the generator driven by the wind turbine is configured to be rectified to DC power by a rectifier via a transformer having a variable transformation ratio, and the buck-boost ratio is appropriately controlled. In addition, it is proposed as a method for increasing power generation efficiency in a wide wind speed range from low wind speed to strong wind speed.

[0009]

In each of the prior arts described above, in the case where the shutter is attached to the blade according to the prior art 1, the structure is complicated and the number of parts is inevitably increased. Since it has not been done, the blades will be damaged in the event of a typhoon or it will be necessary to make the blades strong so that they will not be damaged. And as a result, the cost of the blade or the generator increases, and the weight of the blade increases, making it impossible to rotate the blade efficiently. Further, there is no specific description of a measure for preventing excessive rotation and breakage of the blade in a strong wind.

Further, in the prior art 2, the blades are raised and lowered, and the blades or the rotating body are lowered downward in a strong wind to provide a countermeasure against strong winds. However, in the event of a typhoon or the like, strong winds blow near the ground, so it is hard to say that this is a drastic measure to prevent excessive rotation and breakage of the propeller type blades. In addition, there is a problem in that employing a structure for elevating and lowering the blades increases costs.

In the prior art 3, there is a reference to the structure or material of the blade. The cross section is made hollow with a plate material such as a hard metal plate, and the inside of the hollow is filled with foaming resin. This makes it possible to increase the strength and reduce the weight of the blade, but there is a problem that the structure must be hollow and the production is not easy due to the complicated structure of filling the inside with foam resin.

Further, in the prior art 4, a large number of propeller-type wind turbines are intensively installed on a shelf base,
It states that it will secure a large amount of power generation and reduce the weight and cost of the pillars that support the windmills, but nothing is stated about facing each windmill installed on the shelf base in the windward direction. . If the individual wind turbines are fixed to the gantry, there is a problem that high-efficiency power generation corresponding to a change in wind direction cannot be expected. In addition, if each windmill is freely rotatable with respect to the gantry corresponding to the wind direction, the number of parts for that purpose is increased, and each windmill is required to rotate in the horizontal direction corresponding to the wind direction. Since a rotating area is required, there is a limit to the arrangement of the high-density wind turbine in the gantry, and the installation area of the gantry increases accordingly, and the extra members constituting the gantry increase or the length of the members increases. However, there is a problem that the weight is heavy and the structure is complicated, so that it takes time for installation, repair and inspection, and the cost is high. Furthermore, depending on the direction of the wind, there is a problem that the wind is blocked by a windmill located on the same gantry, so that the windmill on the lee cannot generate electric power with high efficiency.

According to the prior art 5, the output from the generator driven by the windmill is rectified into DC power by a rectifier via a transformer having a variable transformation ratio, and the step-up / step-down ratio is appropriately controlled to achieve a wide wind speed. It is said that the power generation efficiency is increased in the range,
There is a problem that the transformer becomes heavy due to the necessity of the transformer, and a mechanism for controlling the step-up / step-down ratio is required, resulting in high cost.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and has a simple structure without increasing the weight and efficiently receiving the power of the fluid by the blades to generate power efficiently. It is a first object of the present invention to provide a rotary power generator having a high power consumption. Also, it is necessary to prevent the blades from being damaged by excessive fluid force or prevent excessive rotation of the rotating body to prevent excessive power generation exceeding the allowable power generation capacity of the generator. This is the purpose of 2. It is a third object of the present invention to provide a rotary power generator having high power generation efficiency, which has blades that can be easily manufactured and that can be reduced in weight. Also,
It is a fourth object of the present invention to provide a rotary power generator capable of boosting DC voltages from a plurality of generators and rectifiers without using a booster such as a transformer or a chopper.

It is. Reference numeral 11a denotes a blade rotation axis when the blade 1 rotates, and corresponds to a second rotation axis. Reference numeral 12a denotes a rotating body rotation axis when the rotating body 2 rotates, and corresponds to a first rotation axis. The blade rotating shaft 11a and the rotating body rotating shaft 12a are arranged side by side (in this embodiment, in parallel), and the rotating shafts 11a and 12a intersect with the direction 10 in which the fluid flows (this embodiment). It is arranged so that it goes straight). 1x indicates the position of the blade 1 at the lower left of FIG. 1A after rotation (hereinafter, may be referred to as position 1x).

The blade 1 includes a blade frame member 1a for maintaining the shape of the blade 1 and a blade surface member 1b attached to the blade frame member 1a and receiving a fluid force. The material is, for example, stainless steel, and the blade face material 1b
Is a cloth using a transparent or translucent fiber material, for example. In the present embodiment, the blade frame member 1a is provided in the shape of a mouth only on the outer peripheral portion of the blade 1, but may be in the shape of a paddle with the inside reinforced. Reference numeral 1c denotes a guide blade in which an end, which is a part of the blade 1, is bent toward a surface on which the blade 1 receives a fluid force. The rotating body 2 includes the blade 1
In addition, a blade rotating seat 2a that supports rotation of the blade 1 on the rotation outer peripheral portion of the rotating body 2, a rotating body arm 2b that supports the blade rotating seat 2a, and a rotating body center 2 that supports the rotating body arm 2b.
c, a power transmission 2d such as a gear for transmitting the rotation of the rotating body 2 to the power shaft 7 and increasing the rotation speed. In order to increase the structural strength, for example, the rotating body arms 2b may be connected to each other by a structural member at the outer peripheral portion of the rotating body 2.

Hereinafter, each part will be described in more detail.
The center 2c of the rotating body and the column 4 have a double-pipe structure. The inner tube corresponds to the column 4 and the outer tube corresponds to the center 2c of the rotating body. Of the rotating body 2c.
By providing a bearing structure (not shown) between at least one of the support column 4 and the rotary seat 6, or by applying a lubricating oil, resistance due to friction or the like during rotation of the rotating body 2 is reduced. .

The blade rotating seat 2a has a ring shape, and extends in the axial direction of the blade rotating shaft 11a so that a shaft 1e connected to the blade 1 passes through a hole in the ring of the blade rotating seat 2a. Shaft 1 of blade 1 extending in the axial direction of rotating shaft 11a
Between e and the blade rotary seat 2a, a bearing structure (not shown) for reducing friction during rotation or the like is applied or lubricating oil is applied.

The swing limiter 3 has, for example, a cylindrical shape, and has one end fixed to the outer periphery of the blade rotating seat 2a and the other end extending toward the blade 1, and the blade 1 is connected to the blade rotating shaft 11a. When rotated about the center, the blade 1 hits the other end of the swing limiter 3, and the blade 1 is configured not to rotate any more.
The range in which the blade 1 rotates and swings and the direction of rotation are regulated.
The material of the swing limiter 3 is an elastic body such as a hard rubber or a coil-shaped spring, and also serves as a buffer means for absorbing and mitigating the impact and noise when the blade 1 hits. When the blade 1 whose rotation has been limited by the above is subjected to an excessive force from a fluid or an artificially excessive force, the swing limiter 3 made of an elastic body such as a hard rubber or a coil spring may bend. Thus, the blade 1 rotates beyond the swing limiter 3 and also serves as a restriction canceling unit for canceling the rotation limit of the blade 1 by the swing limiter 3.

The generator 5 has a configuration similar to that of a so-called dynamo of a bicycle light that generates AC power by combining a permanent magnet and a coil, for example. Is transmitted through the power transmission 2d and the power shaft 7 to generate AC power. In the case of the present embodiment, two generators 5 connected to the rotating body 2 are installed in parallel with the rotating body 2, but the available power generation capacity of the generator 5 and the rotating body 2 Efficiency when converting the rotational energy by receiving the force of the fluid, the number of revolutions, the allowable maximum flow velocity of the fluid that the rotary power generator can withstand,
It may be appropriately selected according to the effective area when the rotating body receives the force of the fluid, the installation location, and the like. As described above, by connecting a plurality of generators 5 to the rotating body 2 in parallel or in series, a generator having a power generation capacity corresponding to the structure and the installation location of the rotating body 2 as described above is produced exclusively. It is possible to use a combination of a plurality of generators that are mass-produced without the need, and the convenience is improved. Further, a speed-increasing device for increasing the rotation speed may be provided on the way such as a power transmission device 2d or a power shaft 7 which is a means for transmitting the rotation force from the rotating body 2 to the generator 5. This can increase the power generation efficiency of the generator 5.

FIG. 2 is a block diagram showing a power supply system in the rotary power generator according to Embodiment 1 of the present invention. In FIG. 2, 5 is the two generators in FIG. 1, 15 is a rectifier connected to each generator 5 and converting the AC power generated by the generator 5 to DC, and 16 is a rectifier from each rectifier 15. An inverter for converting DC power boosted by connecting DC power in series to AC power, and an AC power system 17 output from the inverter 16. In FIG. 1, the rectifier 15, the inverter 16, and the AC power system 17 are not shown. Note that the DC power output system from each rectifier 15 may include a bypass diode circuit (not shown) for bypassing the system when the DC power output voltage is lower than a predetermined value. In this case, for example, even when one of the two generators 5 fails, the circuit between the rectifier 15 and the inverter 16 is not interrupted, so that the overall output decreases but the power generation operation continues. The effect that can be obtained is obtained.

Next, the operation and operation of the rotary power generating apparatus according to Embodiment 1 of the present invention configured as described above will be described. When the fluid is not flowing, the direction of the blade 1 is unknown, and the blade 1 and the rotating body 2 are stationary, and the generator 5 is not driven. . Next, the fluid flows in direction 10
, The blades 1 or the guide blades 1c receive the drag from the fluid, and rotate in the rotation direction 11 of the blades 1 or in the opposite direction until the blades 1 or the guide blades 1c become parallel to the direction 10 in which the fluid flows. In the case of the present embodiment, since the three blades 1 are arranged at an equal angle with respect to the rotation direction 12 of the rotating body 2, at least one blade 1 (at the lower right of FIG. The blade 1) cannot rotate until it hits the swing limiter 3 and becomes parallel to the direction 10 in which the fluid flows, and continues to receive the drag from the fluid. The rotating body 2 starts rotating in the direction of the rotating direction 12 by obtaining the rotating force.

When the rotating body 2 rotates and reaches the lower left portion of FIG. 1A, the blade 1 located at the lower right of FIG. And the drag is lost, and the drag from the fluid is generated in the guide blade 1c, and the rotation direction 1 around the blade rotation shaft 11a.
1 and starts rotating to a position 1x (however, since the rotating body 2 is rotating, it does not immediately become the position 1x at the lower left of FIG. 1A). At that time, the next blade 1 (the blade 1 located at the upper center in FIG. 1A) already in the direction opposite to the rotation direction 12 of the rotating body 2
(A), it moves to the lower right, hits the swing limiter 3, and receives the drag from the fluid. Unless the flow of the fluid is lost, the continuous rotation of the rotating body 2 continues. Will be done. The blade 1 at the position 1x is located at a position where the blade 1 again hits the swing limiter 3 (FIG. 1).
Until it comes to the position (lower right of (a)), even if the rotating body 2 rotates, it only rotates gently around the blade rotating shaft 11a so as to be parallel to the direction 10 in which the fluid flows. The state is hardly affected by drag.

As described above, in the present embodiment, the blade 1 that moves in the same direction as the direction 10 in which the fluid flows around the rotating body rotation shaft 12a hits the swing limiter 3 and reduces the drag from the fluid. The remaining blades 1 only rotate gently around the blade rotation shaft 11a so as to be parallel to the direction 10 in which the fluid flows even when the rotating body 2 rotates, and almost receive the drag from the fluid. In this state, the power of the fluid is efficiently received by the blades 1 and can be used for the rotation of the rotating body 2 without waste, and the power generation efficiency can be increased.

When the rotating body 2 rotates, two power shafts 7 connected in a gear structure to the power transmitting apparatus 2d via a power transmitting apparatus 2d attached to the rotating body 2 rotate, and each power shaft 7 rotates. The two generators 5 connected to the shaft 7 are driven to generate power. At this time, AC power is output from each of the generators 5 and is converted into DC power by the rectifiers 15 connected to the respective generators 5. The DC output from the rectifier 15 is connected in series, and the current is
The voltage is boosted in substantially the same manner as in the case of 5 alone, input to the inverter 16, converted into AC power, and supplied to the AC power system 17. Therefore, the DC voltage from the plurality of rectifiers 15 can be boosted without using a booster such as a transformer or a chopper, and the transformer does not become heavier as in the related art 5, and the buck-boost ratio is controlled. Since no mechanism is required, an effect of contributing to cost reduction can be obtained.

Next, the operation when the flow velocity of the fluid is excessive will be described. When the flow velocity of the fluid is large (for example,
(In the case of wind, the wind speed is 15 m or more), the drag received by the blade 1 from the fluid is too large, the swing limiter 3 is bent, and the blade 1 cannot be stopped. The rotor 2 rotates to a position where it becomes parallel (or a position where the blade 1 can minimize the drag from the fluid). In this case, the rotating body 2 cannot receive the force from the fluid via the blade 1 and cannot continue to rotate. Either it stops or turns slowly. The flow rate of the fluid is such that the swing limiter 3 bends and the swing rotation of the blade 1 cannot be restricted (the rotation limitation of the blade 1 by the swing limiter 3 is released). , The material, the number, the length from the fixed point to the position where the blade 1 hits, etc., can be easily changed or set to an arbitrary value.

As described above, in the present embodiment, when the blade 1 receives an excessive fluid force or artificially applies an excessive force to the blade 1, the blade 1 As a result, the swing limiter 3 is deformed without being able to receive the rotation of the blade 1 by the swing limiter 3, and the rotation limit of the blade 1 by the swing limiter 3 is released. The blade 1 can be freely rotated, and the blade 1 receives an excessive fluid force.
Can be prevented from being damaged, and the rotation of the rotating body 2 can be stopped artificially during inspection or the like. In addition, feather 1
It is also possible to prevent excessive rotation of the rotating body 2 due to receiving excessive fluid force, thereby preventing excessive power generation exceeding the allowable power generation capacity of the generator.

In the above embodiment, the swing limiter 3
Is made of an elastic body such as a hard rubber or a coiled spring to restrict the range and direction of rotation of the blade 1 and the elasticity of the swing limiter 3 itself. The rotation of the blade 1 is controlled by the force to stop or not to stop, and the impact when the blade 1 hits is absorbed. The swing limiter 3 also serves as a restriction release unit and a buffer unit. However, since the blade 1 located at the upper center of FIG. 1A gradually moves to the lower right of FIG. 1A as the rotating body 2 rotates, the blade rotating shaft 11a of the blade 1 is moved during this time. The rotation about the center is also gradually performed, and the impact when hitting the swing limiter 3 is much smaller than the case where the shutter as described in the related art 1 is used.

In the above embodiment, each of the blades 1 is made of, for example, a blade frame member 1a made of stainless steel and a cloth made of a light-transmitting fiber material fixed to the blade frame member 1a. It is composed of the blade face material 1b, and it is only necessary to fix the blade face material 1b to the blade frame material 1a by, for example, bonding. Since 1b may be thin, the weight of the blade can be reduced. In addition, the blade face material 1b
The material is not limited to the above, and may be, for example, the following. Cloth using various fiber materials such as cotton and chemical fiber. Petrochemical materials such as polycarbonate, acrylic, polypropylene, plastics, synthetic rubber, and vinyl, or natural rubber. Tempered glass. Wood or wood plywood. Thin metal plate. However, by using a material having optical transparency for the blade face member 1b, there is also obtained an effect that deterioration of sunshine conditions around the installation location of the rotary power generation device can be reduced. Further, by using a material having elasticity such as cloth or rubber for the blade face material 1b, when the blade 1 is receiving the drag force of the fluid in the rotation direction of the rotating body 2,
As a result, the surface receiving the drag of the fluid has a concave curved surface shape, so that the force of the fluid can be efficiently converted into the rotational force, and the blade 1 receives the drag of the fluid. When the blade face member 1b is at a non-existent position, the blade face member 1b returns to a flat shape due to its elasticity, and an effect that the drag of the fluid that hinders the rotation of the rotating body 2 can be further reduced can be obtained. The structure of the blade 1 and the material of the blade face material 1b are not limited to the above embodiment, and the blade is used regardless of the horizontal rotation type or the vertical rotation type. The present invention can be applied to all rotary power generators.

Further, as described above, the blade 1 can receive the drag force of the fluid more efficiently by using an elastic material for the blade surface material 1b, but the material of the blade surface material 1b has no elasticity. However, the blade 1 may be configured to have a corrugated shape on the surface to exhibit elasticity, or the blade frame 1a and the blade surface 1b may be connected by an elastic member. Similar effects can be obtained. In the above embodiment, the shape of the blade 1 is a flat plate. However, the blade 1 is not a flat plate, but a curved surface protruding in the rotation direction 12 of the rotating body 2 (the surface receiving the drag force of the fluid is concave). It may be shaped, and also in this case, there is an effect that the blade 1 can receive the drag of the fluid more efficiently.

Embodiment 2 FIG. 3 is a diagram for explaining the configuration and operation of a main part of a rotary type power generator according to Embodiment 2 of the present invention, in which the same reference numerals as in FIG. 1 denote the same or corresponding components. . FIG. 3 is based on the premise that the configuration is the same as that of the first embodiment shown in FIG. 1. It is the schematic which expands and shows the seat 2a periphery. 3A shows a state immediately before the blade 1 collides with the swing limiter 3, FIG. 3B shows a state in which the blade 1 collides with the swing limiter 3, and FIG. The state immediately after the function of the swing limiter 3 becomes invalid due to collision with force (the rotation limitation of the blade 1 by the swing limiter 3 is released) is shown. The following mainly describes differences from the first embodiment.

In FIG. 3, reference numeral 3 denotes a swing limiter as in the case of the first embodiment shown in FIG.
Unlike the swing limiter 3 itself, the swing limiter 3 itself is formed of a rigid metal or the like, and only the periphery of the swing limiter 3 against which the blade 1 hits is covered with an impact buffering material 3b such as rubber. It is designed to absorb and reduce the impact noise and impact of the vehicle. The swing limiter 3 includes a swing limiter rotating shaft 3a.
Direction in which the blades 1 collide with each other (rotation direction 1 of the blades 1)
It is attached to the blade rotation seat 2a so as to rotate to 1). Normally, the rotation of the swing limiter 3 is controlled by the expansion and contraction force of a telescopic spring 3c connecting the blade rotation seat 2a and the swing limiter 3. It is to be supported. Therefore, the extension spring 3c is connected to the blade 1
Also plays a part in absorbing the shock at the time of collision between the swing limiter 3 and the swing limiter 3. On the other hand, when the blade 1 collides with the swing limiter 3 with excessive force, the rotation of the blade 1 cannot be received by the drag of the expansion spring 3c as a result, and the swing limiter 3
(The restriction on the rotation of the blade 1 by the swing limiter 3 is released).

As described above, in the present embodiment, the shock absorbing means for absorbing the shock when the blade 1 rotates around the rotation shaft 11a and hits the swing limiter 3 is the shock absorbing material 3b.
When the blade 1 receives a force equal to or greater than a predetermined value, the swing limiter 3
The restriction canceling means for canceling the rotation restriction is constituted by a swing limiter rotating shaft 3a and a telescopic spring 3c.

In the present embodiment configured as described above, similarly to the first embodiment, the rotating body rotating shaft 1
The blade 1 that moves in the same direction as the direction 10 in which the fluid flows around the center 2a collides with the swing limiter 3 and continues to receive the drag from the fluid. Since it only rotates gently around the blade rotation shaft 11a so as to be parallel to the direction 10 in which the fluid flows, since it is in a state where it hardly receives drag from the fluid,
The power of the fluid can be efficiently received by the blades 1 to increase the power generation efficiency.

When the blade 1 receives an excessive fluid force or artificially applies an excessive force to the blade 1, the blade 1 collides with the swing limiter 3 with an excessive force, and as a result, Feather 1
Is not received by the drag of the expansion spring 3c, and the rotation restriction of the blade 1 by the swing limiter 3 is released. Therefore, the blade 1 is freely rotated, and the blade 1
Can be prevented from being damaged, and the rotation of the rotating body 2 can be stopped artificially during inspection or the like. In addition, feather 1
It is also possible to prevent excessive rotation of the rotating body 2 due to receiving excessive fluid force, thereby preventing excessive power generation exceeding the allowable power generation capacity of the generator.

Incidentally, a spring may be arranged between the blade 1 and the swing limiter 3 to absorb the shock instead of rubber as the shock buffer 3b.

Further, a ring-shaped or coil-shaped spring may be provided at the position of the swing limiter rotating shaft 3a instead of the expansion / contraction spring 3c so that a repulsive force is generated when the swing limiter 3 rotates. .

Embodiment 3 FIG. FIG. 4 is a diagram showing a configuration of a rotary power generator according to Embodiment 3 of the present invention,
(A) is a plan view and (b) is a front view. In FIG. 4, components denoted by the same reference numerals as those in FIG. 1 are the same or equivalent components, and the differences will be mainly described below. In FIG. 4, reference numeral 1 denotes a blade, and in this embodiment, four blades are provided at an equal angle with respect to the rotating surface of the rotating body 2. Reference numeral 1d denotes a rotary seat with blades fixed to the blade 1 and provided so that the blade 1 rotates about the blade rotating shaft 11a with respect to the rotary body 2. The rotary seat with rotary blade 2 in the first embodiment of FIG. It corresponds to a blade rotating seat 2a fixed to the rotating body arm 2b. 2c is the center of the rotating body, and FIG.
In the first embodiment, the structure is such that the rotating body 2 passes through in the vertical direction. However, in the present embodiment, the rotating body 2 is divided into two parts, an upper part and a lower part. Reference numeral 2e denotes a fixed blade fixed to the rotating body 2, which has a curved surface shape, is fixed to the rotating body center portion 2c above and below the rotating body 2, and has a function of receiving a drag force of the fluid, and a function of the rotating body 2. In particular, it also serves as a member for supporting the structure in the vertical direction. Reference numeral 2f denotes a blade rotating shaft that connects rotating body arms 2b above and below the rotating body 2 in the vertical direction along the blade rotating shaft 11a. The rotating seat with blade 1d rotates around the blade rotating shaft 2f. It has become.

Reference numeral 2g denotes an annular support table which is disposed below the rotating body 2, supports the swing limiter 3, and is an annular flat plate which rotates together with the rotating body 2. Reference numeral 2h denotes a coil-shaped up / down swing spring having a spring function for connecting the rotating body 2 and the annular support 2g and extending and contracting in the vertical direction. , 9 is a pull string fixed to the pull member 8, 20 is a pull motor, which takes up the pull string 9 by rotating and pulls down the pull member 8,
And the tension member 8 and the annular support 2g are returned upward by the reaction force of the vertical swinging spring 2h. Reference numeral 21 denotes a flow meter corresponding to a fluid force detecting means for detecting the force of the fluid, and detects the flow speed as the force of the fluid. As the current meter 21, for example, a rotating unit having a plurality of small arm-shaped blades is rotated by the flow of the fluid, and generates a small amount of power by the number of rotations or by the rotation. The type of detection is used.

In this embodiment, when the blade 1 receives a force equal to or greater than a predetermined value, the swing limiter 3
The restriction releasing means for releasing the rotation restriction of the pull member 8
And a pull string 9 and a pull motor 20. Further, as the swing limiter 3, for example, as in the case of the first embodiment, a device formed in a cylindrical shape by an elastic body such as a hard rubber or a coil-shaped spring is used. It may also serve as a buffer means for absorbing and mitigating impact and noise, and may be formed of a rigid body such as a metal as in the case of the second embodiment. An impact buffer may be provided.

Next, the operation and operation of the rotary power generator according to Embodiment 3 of the present invention configured as described above will be described. When the fluid is not flowing, the blade 1 is in an undefined state in which direction it is facing, and no fluid drag is generated on the fixed blade 2e, so that the blade 1 and the rotating body 2 naturally stand still. And the generator 5 is not driven. Next, when the fluid starts flowing from direction 10,
The drag from the fluid is generated in the fixed blade 2e, and the rotating body 2 starts rotating in the rotation direction 12. At the same time, the blades 1 also receive a drag force from the fluid, and the respective blades 1 rotate in the rotation direction 11 or the opposite direction until the blades 1 become parallel to the direction 10 in which the fluid flows or hit the swing limiter 3 and no longer rotate. .

The blade 1 under the drag of FIG. 4A and receiving the drag from the fluid, when the rotating body 2 rotates to reach the left side of FIG. , And loses the drag, and rotates to the position 1x in the direction of rotation 11 about the blade rotation shaft 11a. At that time, the next blade 1 (the blade 1 on the right side of FIG. 4A) has already moved to the lower part of FIG.
As it is in a state of receiving the drag from the fluid, unless the flow of the fluid is lost, the continuous rotating body 2
Is rotated efficiently. In addition, position 1x
The blade 1 in the state described above is kept in a position until the blade 1 again comes into contact with the swing limiter 3 (a lower position in FIG. 4A).
Even if the rotating body 2 rotates, it only rotates gently around the blade rotating shaft 11a so as to be parallel to the direction 10 in which the fluid flows, and is in a state where it receives little drag from the fluid.

As described above, in the present embodiment, the blade 1 that moves in the same direction as the direction 10 in which the fluid flows around the rotary shaft 12a hits the swing limiter 3 and reduces the drag from the fluid. The remaining blades 1 only rotate gently around the blade rotation shaft 11a so as to be parallel to the direction 10 in which the fluid flows even if the rotor 2 rotates, and almost receive the drag from the fluid. In this state, the power of the fluid is efficiently received by the blades 1 and can be used for the rotation of the rotating body 2 without waste, and the power generation efficiency can be increased.

Although the number of generators 5 in the process of rotating the rotating body 2 to convert it into AC power is different, the basic operation and operation are the same as those of the first embodiment. The description is omitted because it is almost the same.

Next, the operation when the flow velocity of the fluid is excessive will be described. When the flow meter 21 detects that the flow of the fluid is equal to or higher than the predetermined permissible flow rate for supporting the structure, the tension motor 20 is driven by an instruction of a controller (not shown) or a relay circuit.
The tension cord 9 is wound up, hooked on the tension member 8, and the annular support 2g is pulled down. As a result, the swing limiter 3 fixed to the annular support 2g is pulled down, so that the blade 1 and the swing limiter 3 cannot contact each other, and the function as the swing limiter 3 is lost. At this time, the rotor 2 only rotates by the drag from the fluid received by the fixed blade 2e. Since the fixed blade 2e is arranged on the center side of the rotation of the rotating body 2, the rotating torque is low, and by appropriately reducing the size of the fixed blade 2e, the rotating force by the fixed blade 2e alone is strong. Rotation does not occur, and even if the flow rate of the fluid is high, it is possible to easily suppress the effect that the rotating body 2 or the support 4 receives from the fluid within an allowable strength range of the structure.

As described above, in the present embodiment, when the blade 1 receives an excessive fluid force, the swing limiter 3 is pulled down by winding up the pull cord 9, and the swing limiter 3 Since the rotation regulation of the blade 1 is released, the blade 1 can be freely rotated, and the blade 1 can be prevented from being damaged by an excessive fluid force. Also, excessive rotation of the rotating body 2 due to the blade 1 receiving excessive fluid force can be prevented, and excessive power generation exceeding the allowable power generation capacity of the generator can be prevented. Furthermore, in the present embodiment, the flow rate meter 21 is actually provided to detect the flow rate. Since the restriction canceling means constituted by the pulley 8, the pull cord 9 and the pull motor 20 is configured to operate, the effect of less malfunction is obtained.

In the above-described embodiment, as the current meter 21, the rotating unit having a plurality of small arm-shaped blades is rotated by the flow of the fluid, and generates a small amount of power by the number of rotations or by the rotation. Although the type that detects the flow velocity of the fluid based on the amount of power generation is used, the present invention is not limited to this.For example, the current flowing through the conductive wire portion is used to maintain the temperature of the conductive wire portion exposed to the fluid flow constant. A so-called hot-wire type flow meter that detects the flow velocity may be used.

In the above-described embodiment, the regulation of the rotation of the blade by the swing limiter 3 is released based on the detection result of the flow meter 21. In this case, the rotation restriction of the blade 1 by the swing limiter 3 may be released. In this case, not only when the flow velocity of the fluid is excessive,
The rotation of the rotating body 2 can be easily stopped at the time of inspection or the like.

Further, in the above embodiment, the case where the flow meter 21 is used as the fluid force detecting means for detecting the force of the fluid has been described. However, the index indicating the force of the fluid is not limited to the flow speed. The rotation speed of the body 2, the pressure at which the fluid collides with the blade 1, the power from the generator 5, the current, the voltage, or the like may be used. Instead of the current meter 21, any of these indices is detected. May be provided, and it may be determined whether or not the rotation restriction of the blade 1 by the swing limiter 3 is released based on the detection result.

In the above embodiment, the case where the rotating seat 1d with the blade is fixed to the end of the blade 1 has been described. T) The rotating seat 1d with blades may be fixed. In the case of the blades 1 having the same length in the rotation normal direction of the rotating body 2,
The diameter of rotation from the blade rotation shaft 11a can be reduced, and the rotation diameter of the rotation body as a whole from the rotation body rotation shaft 12a can be reduced.

Embodiment 4 FIG. 5 is a perspective view illustrating a configuration of a main part of a rotary power generation device according to Embodiment 4 of the present invention, and specifically illustrates a configuration of a rotating body. Other configurations are the same as those of the first embodiment, for example. In FIG. 5, components denoted by the same reference numerals as those in FIG. 1, FIG. 3, or FIG. 4 are the same or corresponding components, and differences will be mainly described below.

In FIG. 5, reference numeral 1 denotes a blade, which is the same as in the third embodiment shown in FIG.
Accordingly, the blade is supported by the blade rotation shaft portion 2f so as to be freely rotatable about the blade rotation shaft 11a. Reference numeral 3 denotes a swing limiter. In the present embodiment, a long rod extending from the upper portion to the lower portion of the blade 1 is used. Reference numeral 3d denotes a swing limiter rotating seat to which the swing limiter 3 is fixed.
Is supported by a blade rotating shaft portion 2f so as to be freely rotatable about a blade rotating shaft 11a by a swing limiter rotating seat 3d. Reference numeral 3c denotes a telescopic spring, and the swing limiter 3 is pulled by pulling the swing limiter 3 toward the rotating body arm 2b.
Is restricted about the blade rotation shaft 11a.

In this embodiment, the swing limiting means for limiting the range or direction in which the blade 1 swings is
It is composed of a swing limiter 3 and a telescopic spring 3c. The telescopic spring 3c functions to support the swing limiter 3 and stop the rotation of the blade 1 about the blade rotation shaft 11a. Also,
The expansion / contraction spring 3c also serves as a buffer means for absorbing and relaxing the impact and noise when the blade 1 collides with the swing limiter 3 by its expansion / contraction force. Further, when the blade 1 receives a force equal to or more than a predetermined value, the restriction releasing means for releasing the rotation restriction of the blade 1 by the rocking limiter 3 is constituted by a telescopic spring 3c and a rocking limiter rotating seat 3d. Have been.

In the above-described structure, when the blade 1 receives the effect from the fluid, the blade rotating shaft portion 2f along the blade rotating shaft 11a is rotated by the ring-shaped rotating seat 1 with the blade.
Since d surrounds, each blade 1 tries to rotate around the blade rotation shaft 11 a to a position parallel to the flow direction of the fluid, and some blades 1 hit the swing limiter 3. When the blade 1 collides with the swing limiter 3, the rotation of the blade 1 about the blade rotation axis 11a is stopped. Therefore, the blade 1 receives the fluid force, and the rotating body 2 is rotated about the rotation body rotation axis 12a by the force. Will rotate.

When the blade 1 collides with the swing limiter 3 and receives an excessive fluid force, the expansion spring 3c extends and the swing limiter 3 is rotated by the swing limiter rotating seat 3d. Rotation about the shaft 11a makes it impossible for the swing limiter 3 to stop the blade 1, and the blade 1 rotates about the blade rotation shaft 11a to a position parallel to the fluid flow direction.
As described above, if the state in which excessive fluid force is generated continues, the rotation of the rotating body 2 stops because the blade 1 cannot receive the fluid effect.

As described above, in the present embodiment, when the blade 1 receives an excessive fluid force or artificially applies an excessive force to the blade 1, the blade 1 When the collision occurs with an excessive force, the expansion spring 3c extends and the rotation restriction of the blade 1 by the swing limiter 3 is released, the blade 1 is freely rotated, and the blade 1 is damaged by an excessive fluid force. Can be prevented, or the rotation of the rotating body 2 can be stopped artificially during inspection or the like. Also, it is possible to prevent excessive rotation of the rotating body 2 due to the blade 1 receiving excessive fluid force, thereby preventing excessive power generation exceeding the allowable power generation capacity of the generator.

In the above-described embodiment, an impact buffer 3b as shown in FIG. The impact at the time of colliding with the vessel 3 can be further absorbed, and the collision sound can be further reduced.

Embodiment 5 6 (a) and 6 (b) are perspective views each showing a configuration of a main part of a rotary power generator according to Embodiment 5 of the present invention. The present embodiment relates to a modification of the structure in which the blade 1 is freely rotatably attached to the rotating body 2, and the other configuration is, for example, the first or third embodiment.

FIG. 6 (a) shows the blade 1 as a blade frame material 1a.
When the blade frame 1a is fixed to the blade face 1b, the edge of the blade frame 1a is rounded into a ring shape,
FIG. 6B shows a case where the blade 1 is formed in a flat plate shape using, for example, stainless steel, fiber reinforced plastic (FRP), carbon fiber, or the like. 2 shows a structure in which the end of the blade 1 is rounded into a cylindrical shape, and the blade rotating shaft portion 2f is passed through the tube.

Both the structures shown in FIGS. 6A and 6B can provide the same effects as those of the above-described embodiments, and can further reduce the cost of the blade 1 by reducing the number of parts. Further, in particular, in the structure shown in FIG. 6B, the portion for supporting the blade 1 can be lengthened, so that the effect that the structural strength between the blade 1 and the rotating body 2 can be enhanced can be obtained.

Embodiment 6 FIG. FIG. 7 is a perspective view illustrating a configuration of a main part of a rotary power generation device according to Embodiment 6 of the present invention, and specifically illustrates a configuration of a rotating body. Other configurations are the same as those of the first embodiment, for example. In FIG. 7, components denoted by the same reference numerals as those in FIG. 1, FIG. 3, FIG. 4, FIG. 5, or FIG. 6 are the same or corresponding components, and differences will be mainly described below.

In FIG. 7, reference numeral 1 denotes a blade which is divided into a plurality of stages (two stages in the figure) of the rotating body 2 and which rotates and swings around a blade rotating shaft 11a, and 2b denotes a cylindrical rotating body. A rotating body arm that supports the outer structure of the rotating body 2 by connecting the central portion 2c and the blade rotating shaft portion 2f, and is arranged above and below the individual blades 1. Reference numeral 3 denotes a cylindrical swing limiter attached to the cylindrical rotating body center 2c in the radial direction of the cylinder, and is made of, for example, an elastic body such as hard rubber or a coil spring. This swing limiter 3 is the first embodiment.
In the same manner as in the case (1), the range and direction of rotation of the blade 1 are regulated. Further, the blade 1 also serves as a buffer means for absorbing and mitigating the impact and noise when the blade 1 hits, and a swing limiter. When the blade 1 whose rotation has been limited by 3 receives an excessive force from the fluid, the swing limiter 3 made of an elastic body such as hard rubber or a coil spring bends, so that the blade 1 swings. It also rotates beyond the motion limiter 3 and also serves as a restriction release means for releasing the rotation restriction of the blade 1 by the swing limiter 3.

In this embodiment, a plurality of blades 1 arranged vertically are configured to rotate and swing about the same blade rotation shaft 11a. In addition to the effect, the individual blades 1 do not need to be forcibly enlarged, and three or more rotating body arms 2b can be provided in the vertical direction of the rotating body 2, so that the structural strength of the rotating body 2 is reduced. It can be easily raised, and the rotating body arm 2b
Even if individual strengths (determined by thickness, material, etc.) are reduced, the effect that the structural strength of the entire rotating body 2 can be easily secured can be obtained.

In the above-described embodiment, the case where the same device as that of the first embodiment is used as the swing limiter 3 is shown. The same effect can be obtained even if the rod is long from the upper part to the lower part.

Is a plan view, (b) is a front view, and (c) is a side view. In FIG. 8, those denoted by the same reference numerals as in FIGS.
They are the same or equivalent, and the following mainly describes the differences.

In FIG. 8, reference numeral 22 denotes a gantry.

A total of four bodies 2 are installed vertically and horizontally, two each. Each rotating body 2 is arranged such that its rotating shaft 12a is parallel (in the present embodiment, it is parallel, but it is not strictly parallel but may be slightly out of parallel). The blades 1 face in the same direction indicated by an arrow 24 in the figure along the rotation axis 12a (the direction in which each blade 1 faces is defined as the direction of the gantry 22, and hereinafter, the direction 24 of the wings 1 or the It may be described as a direction 24.) They are installed on the same plane. In addition, the rotating direction of each rotating body 2 is set such that the left and right rotating bodies 2 rotate in opposite directions with the support column 4 as a symmetric axis in order to cancel any vibrations caused by the rotation of the plurality of rotating bodies 2. are doing. Furthermore, it is installed so that the rotating direction of the upper and lower rotating bodies 2 is opposite to the vertical direction. The diameter of the rotating surface of the blade 1 attached to the rotating body 2 is approximately 1 meter.

The rectifying plate 22a is a direction perpendicular to a surface of the blade 1 which receives the fluid force (a surface on which the blades 1 are arranged), that is, the rotating body rotating shaft 12a.
It extends in a direction parallel to. In FIG. 8C, the current plate 22a on the near side is removed. Reference numeral 22b denotes a gantry frame which forms the outer structure of the gantry 22 and supports the individual rotating body 2, the generator 5, the rectifying plate 22a, and the like. For example, pipes made of stainless steel, L-shaped steel, H-shaped steel, B-shaped steel, An outer frame of the gantry 22 is formed using a mold steel or the like, and the gantry 22 is formed of a portion such as a support member for fixing the individual rotating bodies 2, the generator 5, the rectifying plates 22a, and the like to the gantry 22. Reference numeral 22c denotes a center of the gantry, which has a columnar shape and corresponds to an outer tube for the column 4 of the inner tube in the double-tube structure.
And a support structure 4 (not shown)
It is designed to rotate freely around. 13a is a gantry rotating shaft. Specifically, the case where the fluid is wind is described below. Usually, the column 4 is fixed to the ground or the like in the vertical direction, and the wind blows in the horizontal direction. Therefore, the gantry 2
Numeral 2 rotates and swings around a gantry rotating shaft 13a that intersects (actually substantially perpendicularly) the direction in which the wind blows.

Reference numeral 22d denotes a gantry power transmitter, 25 denotes a gantry drive motor capable of rotating in both forward and reverse directions, and 27 denotes a gantry drive shaft. These gantry power transmitter 22d and gantry drive motor 25

A gantry driving means for rotating and driving about 3a is configured. That is, when the gantry drive motor 25 is rotated, the gantry drive motor 22 is transmitted to the gantry power transmitter 22 d via the gantry drive shaft 27, so that the gantry 22 can be rotated. Reference numeral 23 denotes a flow direction detecting means for detecting the flow direction 10 of the fluid, and is, for example, a weathercock type direction indicator.
Reference numeral 26 denotes a gantry rotating seat, which prevents the support column 4 and the gantry 22 from shifting up and down, and has a bearing structure (not shown) between the gantry 22 and the gantry 22 to reduce resistance due to friction and the like when the gantry 22 rotates. ing. Reference numeral 28 denotes a brake pump fixed to the column 4, and reference numeral 28 a denotes a brake pad attached to a shaft extending from the brake pump 28, which constitutes a gantry stopping means for stopping the rotation of the gantry 22. That is, by driving the brake pump 28, the brake pad 28a moves up and down, and the brake pad 2
8a can contact the lower part of the gantry power transmitter 22d.

Next, the operation will be described. When the fluid flows, the direction of flow of the fluid is determined by a weathercock type direction indicator 23.

5, the gantry 22 is constantly controlled such that its direction is opposite to the flow direction 10 of the fluid detected by the direction meter 23 (toward the upstream direction of the fluid). As a result, the power of the fluid can always be efficiently received by the blade 1, the rotating body 2 rotates efficiently, the generator 5 is driven via the power shaft 7, and the power generation is efficiently performed. Become. At this time, the current plate 22a
As a result, the fluid hitting the blade 1 is less likely to laterally move, and the drag of the fluid is transmitted to the blade 1 more efficiently.

At the time of maintenance such as repair or inspection of the gantry 22 and the rotating body 2, the brake pump 28
To drive the brake pad 28a to the gantry power transmitter 22
d, the rotational swing of the gantry 22 can be stopped by friction. When the brake pump 28 is driven, the driving power of the gantry driving motor 25 is stopped, or the gantry driving motor 25 is driven in advance or the gantry 22 is rotated manually, and the direction 24 of the gantry 22 is The angle may be approximately 90 degrees with the flow direction of the fluid detected at 23. By doing so, the rotation of the rotating body 2 can also be stopped or made gentle.

As described above, in this embodiment, the gantry 22 in which the four rotating bodies 2 are arranged so that the respective rotating shafts 12a are parallel to each other is provided, and the gantry 22 intersects with the fluid flow direction 10. It is configured to be rotatable about the gantry rotating shaft 13a, and the position where the rotating body 2 rotates most efficiently in the direction 10 in which the fluid flows (the blades 1 of the rotating body 2).
By rotating the gantry to a position where it faces the upstream direction of the fluid), the power of the fluid can be efficiently received by the blades 1 to increase the power generation efficiency. Further, when the fluid force is excessive, such as when the flow velocity is excessive, the direction

Further, a direction meter 23 for detecting the direction 10 of fluid flow and a controller for controlling the gantry drive motor 25 in correspondence with the direction 10 of fluid flow detected by the direction meter 23 are provided. , Fluid flow direction 10
Is actually detected, and the gantry 22 is rotationally driven so that the direction thereof faces the direction 10 in which the fluid flows (the blades 1 of the rotating body 2 face the upstream direction of the fluid), thereby ensuring high power generation efficiency. Is obtained.

Further, since the rectifying plate 22a is provided,
For normal power generation, it is possible to enhance the rotational efficiency of the rotating body 2 by promoting the flow of fluid into the rotating body 2, stabilize the direction 24 of the gantry 22 in a direction that is easy to receive the fluid flow,
When the gantry 22 is rotated so that the direction 24 of the blades 1 of the rotating body 2 is deviated from the direction 10 in which the fluid flows when the force of the fluid is excessive such as at the time of an excessive flow velocity, the rotating body 2 Fluid inflow can be suppressed.

In the above-described embodiment, the case where the rectifying plate 22a is provided on the side surface of the gantry 22 has been described. However, the present invention is not limited to this. It may be provided.

In the above embodiment, the gantry 22 is rotated by the electric gantry drive motor 25. However, the gantry 22 may be rotated by a hydraulic mechanism, for example.

Further, without providing the direction meter 23 and the gantry driving motor 25, the force of the blade fluid which can be obtained by extending the current plate 22a, for example, the current plate 22a in the direction of the rotating shaft 12a of the rotating body 2, is provided. A direction wing extending in a direction perpendicular to the receiving surface may be provided, and the direction 24 of the gantry 22 may naturally oppose the flow direction 10 of the fluid by the action of the rectifying plate 22a and the direction wing.

In the above embodiment, the brake pad 28a is brought into contact with the gantry power
Is stopped, but the contact partner of the brake pad 28a may be another part of the gantry 22 or may be the gantry drive shaft 27 or the like.

In the above embodiment, the gantry stopping means for stopping the rotation of the gantry 22 is constituted by the brake pump 28 and the brake pad 28a. However, the present invention is not limited to this. The mechanism may be a mechanism that tightens in a shape, or a mechanism that exerts a braking force against the rotational swing of the gantry 22 when manually pressed or pulled by a person.

In the above embodiment, two individual rotating bodies 2 are installed vertically and horizontally on the gantry 22.
The number of units in the vertical and horizontal directions is not limited to this, and may be any number. However, if the number is increased laterally, the distance from the gantry rotation shaft 13a to the outer edge of the gantry 22 is increased, and the radius of the rotating surface of the gantry 22 is increased, so that it is difficult to install the gantry 22 in a narrow installation place. The torque for rotation is large and the driving force is increased (especially when the direction 24 of the gantry 22 needs to have an angle of about 90 degrees with the flow direction of the fluid detected by the direction indicator 23, such as when the flow velocity is excessively large. ), Due to the effect from the fluid and the fluctuation of the fluid (particularly when the fluid is wind, etc., the fluid does not flow uniformly at a constant flow rate in a constant direction), and tends to fall in the direction in which the gantry 22 extends. The strength of the gantry 22 and the struts 4 is strengthened (for example, by increasing the thickness and thickness of the members constituting the gantry 22 and the struts 4 and increasing the number of beams, etc.) That) Or become essential, also when increasing the number both vertically and horizontally, the gantry 22 fluid so as to avoid the entire gantry 22
The rotating body 2 in the central part of the surface receiving the fluid decreases the power generation efficiency or the like.
When increasing the amount of power generation by increasing the area receiving the fluid (air receiving area), the number of horizontal units should be suppressed to two or at most a unit that can fit within about 1-2 m from the gantry rotating shaft 13a. It is better to increase the number as much as possible.

Further, in the above embodiment, the diameter of the rotating surface of the blade 1 attached to the rotating body 2 is assumed to be 1 meter, but the present invention is not limited to this. However, feather 1
In order to secure the structural strength described above, the diameter of the rotating surface of the blade 1 attached to the rotating body 2 should not be so large from the viewpoint of cost reduction, and is preferably about several tens cm to 2 m.

In the above-described embodiment, the propeller-type rotating body 2 of the vertical rotary power generator that rotates in the vertical direction by receiving the force of the fluid flow from the rotating body rotating shaft 12a.
Although the case where a plurality of are installed on the gantry 22 is shown,
Horizontal rotation, such as the general Savonius type, which rotates in the horizontal direction by receiving the force of the fluid flow from the direction perpendicular to the rotating body rotation shaft 12a, and those shown in the first to sixth embodiments, etc. A plurality of rotating bodies having a cylindrical appearance with a cylindrical appearance may be rotated 90 degrees and turned sideways, and installed on a gantry such that the rotating shafts 12a of the rotating bodies are parallel.

Further, the above-described horizontal rotating type power generating apparatus, in which the rotating body 2 having a cylindrical appearance is turned sideways, is disposed, for example, one by one on the left and right sides of the column 4, and the rotating body 2 rotates to generate power. One generator 5 may be installed on the gantry 22 at the position of the support 4, and the generator 5 may be shared by the two rotating bodies 2 arranged on the left and right of the support. In this case, Thus, the number of generators 5 provided for each rotating body 2 can be reduced. In addition, when the horizontal rotary power generation device as shown in the above-described first to sixth embodiments is installed horizontally on a gantry, the position of the blade is determined by gravity (particularly from the blade rotation axis) particularly when the flow velocity of the fluid is low. The blade is hanging downward or in a position regulated by the swing limiter), so that the rotation direction of the rotating body shown in the first to sixth embodiments can be determined,
The guide blade 1c and the fixed blade 2e required for starting the rotation can be omitted.

In FIG. 8, the individual blades 1 are drawn as rectangular plates, but they may be so-called streamlined blades, and the number of blades 1 may be two or more. Further, the blade 1 may be composed of the blade frame member 1a and the blade surface member 1b as described in the first embodiment, and the material of the blade frame member 1a and the blade surface member 1b is also The one described in Embodiment Mode 1 may be used.

Embodiment 8 FIG. FIG. 9 is a diagram showing a configuration of a rotary power generation device according to Embodiment 8 of the present invention, and (a).
Is a front view, and (b) is a side view. In FIG. 9, FIG.
The same reference numerals as those in FIG. 8 to FIG. 8 denote the same or corresponding components, and the following mainly describes the differences. FIG. 9 shows a modified example of a method of arranging the rotating body 2 on the gantry 22. The direction indicator 23, the brake pump 28, the rectifying plate 22a, etc. in FIG. Omitted for simplicity.

In FIG. 8 of the seventh embodiment, each rotating body 2
When the generator 5 was provided on the gantry 22, a plurality of generators 5 were arranged in a matrix at the same height position,
In FIG. 9, a total of four generators 5 and a rotating body 2 are directly attached to the gantry center 22c while changing the height position on the left and right. Therefore, a support member for supporting the rotating body 2 and the generator 5 on the gantry 22 can be omitted (the rotating body 2).
It is only necessary to attach the generator 5 to the gantry center 22c. 8), the gantry frame 22b in FIG. 8 can be simplified or omitted, and the distance from the gantry rotation shaft 13a to the outer edge of the gantry 22 can be shortened.
This has the effect of further reducing the structural strength. Note that a straightening plate (not shown) may be attached, for example, in a cylindrical shape along the outer circumference of a rotating surface (a circle shown by a dotted line in the figure) of the rotating body 2 (or the blade 1).

In the above embodiment, the portion of the generator 5 is directly fixed to the gantry center portion 22c.
c and the generator 5 with a little more space therebetween via a joining member (for example, the distance from the gantry rotation axis 13a to the rotation body rotation axis 12a is set to ^30.5 / 2 of the radius of the rotation surface of the rotation body = about ^0.5 mm).
Separate about 87 times. In this case, the installation density of the rotator 2 in the length direction of the support 4 can be increased, and the number of the rotators 2 installed in the same length of the support 4 can be increased. There is an effect that the length of the support 4 can be made shorter.

Further, in the above embodiment, the blades 1 of each rotating body 2 are installed so as to be aligned on the same plane with respect to the column 4, but when viewed from the front, the height position is changed on the left and right. Similarly to the case where the rotating body 2 is installed, the rotating body 2 is installed by shifting the rotating surface back and forth with respect to the direction in which the fluid flows, and when viewed from the front, the rotating body 2 adjacent vertically or horizontally ( The blades 1) may be installed so that the rotation surfaces (circles shown by dotted lines in the figure) partially overlap. In this case, there is an effect that the installation density of the rotating body 2 in the length direction of the support 4 can be further increased. However, especially in the rotator 2 on the leeward side where the rotating surfaces overlap, the flow velocity of the fluid is weakened by the rotator 2 on the leeward side and the efficiency is reduced. Therefore, it is desirable to reduce the overlapping portion as much as possible. As a method of shifting the rotating surface back and forth, the support column 4 is sandwiched (for example, while the mounting position of the generator 5 is the same, the direction in which the power shaft 7 is extended and the mounting position of the rotating body 2 are alternately changed back and forth. )
Also, regardless of the fluid flow velocity, the rotational center of gravity of the gantry 22 can always be the same as or close to the same as the gantry rotating shaft 13a. , The gantry 22 can be easily rotated.

It should be noted that shifting the plane of rotation back and forth as described above can also be implemented in the seventh embodiment, and similar effects can be obtained.

Embodiment 9 FIG. FIG. 10 is a view for explaining a rotary power generator according to Embodiment 9 of the present invention. Specifically, a rotary power generator having the configuration of Embodiments 7 and 8 shown in FIGS. It is a block diagram explaining operation | movement of a gantry direction control means. In the present embodiment, the direction 24 of the gantry 22 is controlled so that when the power of the fluid is equal to or more than the allowable value, power generation can be performed while preventing the amount of power generated by the generator 5 from becoming excessive. .

In FIG. 10, reference numeral 30 denotes a detected value of the actual power generation amount (electric power) generated by the generator 5, which is one of indexes indicating the power of the fluid. The detected power generation value 30 is, for example, as shown in FIG.
Is calculated by the product of the voltage and the current detected by the voltmeter and the ammeter provided on the input (DC) side of the inverter 16 in. Numeral 31 denotes an allowable maximum power generation amount that is allowable from the structural aspect of the rotary power generator or the electrical capacity of the generator 5, and 32 denotes a direction 2 of the gantry 22 with respect to the fluid flow direction.
The shift angle is 4, and the operation range is -90 to 0 degrees or 0 to 90 degrees. Reference numeral 33 denotes a shift angle 3 according to the deviation between the maximum allowable power generation 31 and the detected power generation value 30.
2 is a maximum power generation amount controller for suppressing the power generation amount detection value 30 to be equal to or less than the allowable maximum power generation amount 31 by operating, for example, a microcomputer. 34 is a flow direction detection value of the fluid detected by the direction indicator 23, 35
Is the direction 2 of the gantry 22 detected by a detector (not shown).
A gantry direction detection value of 4 (direction of the rotating body rotation axis 12a), 36 is a subtractor, 37 is a deviation angle between the fluid flow direction detection value 34 calculated by the subtractor 36 and the gantry direction detection value 35, 38 Is a gantry drive motor drive command for specifying a drive method of the gantry drive motor 25, such as a rotation speed, a rotation direction, and a rotation time of the gantry drive motor 25, and 39 is in accordance with a deviation between the shift angle 32 and the shift angle 37. By operating the gantry drive motor drive command 38, the shift angle 32 and the shift angle 37
Is a misalignment angle controller that performs control so as to match with the maximum power generation amount controller 33, for example, by a microcomputer. The calculation of the power generation amount, the control calculation of the maximum power generation amount controller 33 and the deviation angle controller 39, and other calculation processes such as subtraction and addition are all described above.
It is performed by one or more microcomputers having a CPU and an input / output unit.

Next, the operation will be described. When the power generation amount detection value 30 is smaller than the allowable maximum power generation amount 31, the shift angle 3 which is the operation output of the maximum power generation amount controller 33 is steadily obtained.
2 is 0 degree, and the operation of the shift angle controller 39 causes the gantry direction detection value 35 and the fluid flow direction detection value 34 to always match (the direction 24 of the gantry 22 is opposed to the direction 10 of fluid flow). , And the generator 5 is in the maximum power generation state corresponding to the effectiveness of the fluid flow at that time. When the flow rate of the fluid increases and the detected power generation value 30 is equal to or greater than the allowable maximum power generation 31, the maximum power generation controller 33 sets the shift angle 32, which is the operation output, larger than 0 degrees (the operation range is 0 to 90). (When the operation range is -90 to 0 degrees), and the shift angle controller 39 operates so that the shift angle 37 coincides with the shift angle 32. The direction 24 of 22 deviates from the flow direction 10 of the fluid, the drag of the fluid impinging on the blade 1 decreases, and as a result, the amount of power generated by the generator 5 decreases as compared with the case where the shift angle 32 is 0 degree. Control can be performed so that the detected power generation value 30 does not exceed the maximum allowable power generation 31.

As described above, in the present embodiment, the force (power generation amount) of the fluid is detected, and when the force of the fluid is smaller than the predetermined value, the direction 24 of the blade 1 of the rotating body 2 disposed on the gantry 22 is determined.
The gantry driving means (the gantry driving motor 25) is controlled so as to face the flow direction 10 of the fluid, and when the force of the fluid is equal to or more than a predetermined value, the direction of the blade 1 is changed to the direction 1
The gantry driving means (the gantry driving motor 2
5), the direction 24 of the gantry 22 is controlled in accordance with the actually detected fluid force, so that the blade 1 efficiently receives the fluid force, It is possible to reliably prevent the blade 1 from being damaged by the force of the fluid and to prevent excessive power generation exceeding the allowable power generation capacity of the generator 5 due to excessive rotation of the rotating body 2.

When the current plate 22a is provided, when the direction 24 of the gantry 22 deviates from the flow direction 10 of the fluid, the drag of the fluid impinging on the blade 1 can be reduced more remarkably. In an extreme case, when the direction 24 of the gantry 22 has an angle of 90 degrees with respect to the flow direction 10 of the fluid, the flow of the fluid is prevented from directly hitting the blade 1 by the rectifying plate 22a. 2 hardly rotates.

It may be provided with a photocatalyst layer on which a thin film is adhered or a paint containing a photocatalyst is applied. Further, a sheet formed by mixing a photocatalyst into a polymer material may be used as the blade face material 1b itself. When a photocatalyst receives ultraviolet light (contained in sunlight, fluorescent lamps, etc.), it promotes oxidation, reduction, and decomposition reactions at the contact surface between the photocatalyst layer and air. Some N
It has a function of decomposing or reacting O _x , SO _x , CO, etc. into harmless substances or odorless substances (eg, CO ₂ , H ₂ O, H ₂ , N ₂ , O ₂ ). Is well known. In addition, since the photocatalyst decomposes organic substances and the like attached to the surface, the surface is hardly stained, and has an antibacterial action and a deodorant action.
Deodorants include those that resemble the leaves of houseplants with a photocatalyst coated on the surface (the light source is sunlight or room light), and those that use a fan or the like to blow air through a sheet of photocatalyst with an ultraviolet lamp. It is a product as a device or an air purifier.

Therefore, by providing the photocatalyst in a rotating part such as a rotating body as described above, the chance of contact between the photocatalyst and the fluid naturally increases without using power, so that the fluid can be efficiently purified. There is an effect that can be.

In the case where the blade 1 is made of a material having optical transparency, for example, the blade 1 is provided with a photocatalyst layer on the back side of the surface (the wind receiving surface in the case of wind). In this case, in addition to the effect of being able to purify the fluid efficiently as described above, it is possible to prevent deterioration of the photocatalyst layer due to contact with the fluid (weathering when the fluid is wind). In addition, there is also an effect that the time during which the function as a photocatalyst is obtained can be prolonged (life extension).

Although the above embodiment has been described with reference to the case where the fluid is air, the present invention is not limited to this.
The fluid may be, for example, water, which can decompose organic matter in the water and purify the water.

Note that the photocatalyst is not limited to the rotary power generating device shown in each of the above embodiments, but may be arranged in another rotary power generating device. In this case, the same effect as in the above embodiment can be obtained. can get.
