Description

TECHNICAL FIELD The present invention relates to a floating body equipped with a power generator for floating on water to generate electricity, and an artificial upwelling current generator equipped with the floating body.
In particular, the present invention provides wave power generation by vertical motion of waves (circular orbital motion of water particles) or the floating body, and generates electricity using ocean energy by ocean currents, tidal currents, or the floating body, The present invention relates to the field of energy conversion, such as offshore wind power generation in which offshore wind turbines are mounted on the floating body.

Furthermore, the present invention is in the field of power conversion such as pump power generation using the power source described above, and the field of water quality environment improvement by floating and landing on the ocean, water supply, water intake, water circulation, water purification, etc. It also relates to the improvement of the biological environment, such as phytoplankton aquaculture, fishery resource aquaculture, and sea area fertilization, due to artificial upwelling caused by deep water (bottom water) intake, drainage, diffusion, etc.

Global warming and various destruction of the global environment have long been called for, but these problems have become more serious in recent years. These are also closely related to the problem of carbon dioxide emissions due to the use of fossil energy resources. Fossil energy resources have quantitative problems such as depletion problems of the energy resources themselves. In response to these problems, energy saving and resource saving are being called for, and the early introduction and early practical application of clean natural energy that does not emit carbon dioxide has become a global issue.

Electric energy is supplied by nuclear power generation, but problems related to the use of nuclear power include the deterioration of nuclear reactors at nuclear power plants and the radioactivity that can occur due to earthquakes, tsunamis, natural disasters, man-made disasters, etc. There is a leakage accident. As is well known, radioactivity has a great negative impact on the ecological environment, and when a radioactive leakage accident occurs, as can be seen from examples such as the Fukushima nuclear power plant accident, the adverse impact on the living environment of local residents is extremely large. is likely to cause serious damage.

In addition, with the increase in the scale of wind energy utilization equipment on land in Japan, there are pollution problems such as low-frequency noise problems. In Japan, which has a small land area and a large mountainous area, considering these problems, it is difficult to locate new large-scale land power plants, but new energy development must be promoted as soon as possible. . Therefore, it is urgently required to greatly improve and promote existing equipment in terms of safety, stability, efficiency, maintainability, etc., while taking into consideration the problems of noise pollution and environmental pollution.

Seventy-one percent of the surface area of the earth is ocean, and Japan is a maritime country surrounded by oceans on all sides. In addition, Japan is one of the world's leading powers, including the area of its territorial waters and exclusive economic zone. Therefore, by making effective use of the sea and installing a floating type, a fixed type, or an offshore wind energy utilization device on the sea, it is possible not only to solve the problem of pollution such as low frequency noise but also to increase the scale. Become. Therefore, it is possible to make full use of wind energy as an alternative energy to nuclear power generation.

In addition, the development of wind energy utilization equipment on remote islands will make it possible to live on uninhabited islands that are currently uninhabitable, such as the Senkaku Islands and the Ogasawara Islands, regardless of whether they are on land or at sea. In addition, in order to increase the possibility of using these islands as fishing spots and tourist destinations, we will also improve the lives and convenience of islanders by saving transportation costs such as oil and energy resources on remote islands and expanding tourism and fishery industries. Effective use of the sea is also beneficial in order to improve the quality of life of the people, or to promote wide-area activities of the people and decentralize the population concentrated in urban areas.

There are many marine energy resources such as wave energy, wind power, sunlight, ocean currents, and tides in the ocean. Therefore, by using a device (see Patent Document 1) in which these are mounted on a single floating body, energy can be used inexpensively, safely, and efficiently, and a wide variety of energy sources with different properties can be combined and effectively used as a stable energy source. The development of power generators due to the diversification of energy is desired.

In addition, 4.6 billion years have passed since the birth of the earth, and nutrient salts such as nitrogen and phosphorus that have flowed in from the land are inexhaustibly present on the ocean floor. These are combined with a floating body support shaft and a vertical water intake pipe related to the present invention (see Patent Document 2) to pump deep water in the lower layer (bottom water) to the surface of the sea and increase phytoplankton by artificial upwelling. Aquaculture and multiplication of aquatic food resources extend beyond electrical technology fields such as generators and mechanical and structural technology fields to the ocean ecosystem, biological environment, and biological resource production fields. Therefore, it is socially and economically necessary to develop these as soon as possible. As a first step, the development of the most familiar wave power generation, ocean current, tidal current, offshore wind power, and offshore wind energy utilization equipment is necessary. Urgently wanted.

Japanese Patent No. 5688764 JP 2016-114057 A

In Patent Document 1, the applicant of the present application proposed a wave energy utilization device as a device for generating electricity using wave power by providing a water intake and a water discharge port on an inclined surface of a floating body that floats on the water surface. However, among them, in the structure of the floating body that takes in the wave power (water) in the wave power generator and the structure of the device, it has been desired to further improve the mechanism and make it more efficient.
There is also room for improvement in terms of mechanical troubles, biofouling problems in marine equipment, contamination problems of fish, jellyfish, etc., and reduction of operating work.

Moreover, in Patent Document 2, since the pumped deep-sea water is immediately discharged into the sea, there is a drawback that the settling speed of the discharged deep-sea water into the deep sea is high. As an effective countermeasure against this drawback, the pumped deep water is circulated in the device to prevent adhesion of marine organisms in the device. It is conceivable to discharge the water after the temperature difference between the cold water and the surface water has been mitigated into the sea area.

However, in this case, since the settling velocity of the discharged deep water to the lower layer is slow, the residence time near the surface of the sea is long and the photosynthetic effect is large. As a result, more phytoplankton proliferates, and as a result, the proliferation of zooplankton that preys on the phytoplankton is also promoted, resulting in an increase in deposits on the apparatus caused by these planktons. Therefore, the apparatus must be improved. I had a problem not to.

In particular, for floating wave power and offshore wind energy utilization equipment, the mechanism is simplified as the scale of the equipment increases as it is put into practical use. , simplification of installation, etc., leading to cost reductions in all aspects such as maintenance costs and operating costs, will lead to reductions in power generation costs, etc. For this reason, there was also a problem that it was necessary to reduce the on-site work on the sea as much as possible.

In addition, when transporting, installing, or towing offshore wind energy utilization equipment, etc., it is possible to lower the center of gravity by injecting ballast water into the self-floating body and make it a stable equipment. In the event of a gust of wind, it had to be able to respond easily and keep the equipment safe.

The present invention has been made by paying attention to the problems and problems that the conventional technology has, and is to efficiently perform water intake and drainage in order to perform water power generation using wave power, ocean currents, tidal currents, and wind power. a floating body capable of preventing marine organisms such as jellyfish and fish and floating debris from entering the device mechanism, and an artificial upwelling current generating device equipped with the floating body. do.

FIG. 3 is a view taken along the line XX in FIG. 1, showing the water power generation floating body 1 in a plan view.
As shown in FIG. 3, the assembly of the converging floating bodies 4 forms the substantially circular or substantially regular polygonal water power generating floating body 1 in plan view. An inclined plate floating body 10 having inclined plates 5 is sandwiched between the convergent floating bodies 4. In the middle of the inclined plate 5 of the inclined plate floating body 10 is a drain port for deep water (bottom water) ST, which will be described later. 11 is provided. A check valve 12 is provided at the drain port 11 .

As shown in FIG. 1, the bottom plate 6 of the main tank MT is provided with a water intake port 13 that communicates with the lower outside to take in surrounding water into the main tank MT. The water intake port 13 is provided with a check valve 14 so that water can flow into the main tank MT from the outside thereof but cannot flow out. That is, the check valve 14 is configured to open when water is taken into the main tank MT from the outside below it, and to close when the water flows backward.

Deep water (bottom water) ST pumped up through a vertical water intake pipe 7 by driving the water intake pump 8 is discharged through a nozzle 15 a upstream of the water intake 13 and the check valve 14 . The external perimeter is permeated. In addition, a prevention net 72a is provided outside the water intake 13 to prevent the inflow of floating matter, jellyfish, seaweed, etc., and to prevent the rapid fall of deep water.

A plurality of drain tanks WT are arranged below the main tank MT. The bottom plate 6 of the main tank MT is provided with a communication port 16 communicating with each drain tank WT for each drain tank WT. Therefore, the water inside the main tank MT flows from each communication port 16 into the inside of the drain tank WT. A water wheel 17 is provided in the communication port 16 here.

The water turbine 17 is rotated by water flowing from inside the main tank MT into the inside of the drain tank WT. The water wheel 17 is provided at the lower end of the water wheel rotating shaft 18 . The water wheel rotating shaft 18 is inserted through a protective tube 20 for protection. The upper end of the water turbine rotating shaft 18 is connected to a generator 19 provided in the operator's cab 2 . Therefore, the rotation of the water turbine 17 is transmitted to the generator 19 to rotate the generator 19 and generate electricity. That is, the wave power generation device 70 operates. A prevention net 73 is provided to cover the upper opening of the communication port 16 to prevent impurities such as shells and seaweed from flowing into the communication port 16 from inside the main tank MT.

A structural floor 21 is provided at approximately the same level as the cover plate of the cover 3 above the main tank MT. A stay duct (post) 22 is provided outside the protection pipe 20 from here to the driver's cab 2 above. Under the floor of the driver's cab 2, the stay duct (post) 22 serves as an air passage for the upper part of the main tank due to the vertical movement of the water level in the main tank MT. The stay duct 22 is provided with an intake/exhaust port 23 .

The stay duct 22 also serves as a pillar supporting the driver's cab 2, the windmill 66, etc., which are provided above the main tank MT. That is, the stay duct 22 also plays a major role as a structural member that connects the floating body for power generation 1 and the operator's cab 2 . In addition, the intake/exhaust port 23 of the stay duct 22 is configured so that splashed water or the like does not enter during a big wave.

A spiral plate 45 b is provided inside the lower portion of the stay duct 22 . The spiral plate 45b guides the protection tube 20 and also functions as a light shielding means for shielding light from the intake/exhaust port 23 and the like. This light shielding means will be described later in detail, taking the one provided in the stay duct 39 shown in FIG. 10 as a representative.

Below the water wheel rotating shaft 18 and directly above the water wheel 17, a shaft coupling 24 is provided as a water wheel rotation transmission hardware. A spline groove or the like is provided between the shaft coupling 24 and the water wheel rotating shaft 18, so that the water wheel rotating shaft 18 can be easily removed during maintenance or the like. Similarly, the protective tube 20 described above is also connected directly above the water turbine 17 using a connecting hardware 25, so that the water turbine 17 and the protective tube 20 can be easily separated during maintenance. In addition, the generator 19, the water turbine rotating shaft 18, and the protection tube 20 are structured so that they can be easily lifted upward using a wire, a rope 26, or the like during maintenance.

The water inside the main tank MT is configured to flow inside the drain tank WT. Drainage ports 27 and 28 are provided below the drainage tank WT. A check valve 29 is provided at the drain port 27 and a check valve 30 is provided at the drain port 28 . Here, the check valves 29 and 30 are configured to open when the water inside the drain tank WT is drained to the outside of the floating body, and to close when the water flows backward.

Specifically, the check valves 29 and 30 are opened when the circular orbital motion of the water particles after the wave passes below the floating body is downward, and the water in the drain tank WT can be drained. Since the check valves 29, 30 are closed, the water in the drain tank WT is not drained. Further, water is drained to the upper surface of the inclined plate 5 from the drain port 11 provided in the inclined plate 5 above the drain tank WT depending on the driving and operating conditions. The drain port 11 is provided with a check valve 12 which opens when the water inside the floating body is discharged to the upper surface of the inclined plate 5 but closes to prevent the water from flowing in from the outside.

Above the check valves 29 and 30 in the drain ports 27 and 28, hooks (not shown) to which the wire ropes 31 and 32 are tied are provided. tied up. The other ends of the wire ropes 31, 32 are led to a pulley provided on the ceiling of the cab 2, and are pulled, tied, and locked for manual opening and closing of the check valves 29, 30. etc. can be done easily. The wire ropes 31,32 are passed through protective tubes 33,34 and protected by the protective tubes 33,34. Further, bender pipes or the like are used to guide the wire ropes 31 and 32 where the wire ropes 31 and 32 are bent.

The protective tube 33 extends through the converging floating body 4 to the operator's cab 2 . A stay duct 35 is provided from the upper portion of the converging floating body 4 to the point where the protection pipe 33 penetrates the floor of the operator's cab 2 . The stay duct 35 also serves as a support, and serves as both the air passage in the convergent floating body 4 and the main structural column.

The bottom plate 6 of the main tank MT, which is also the upper plate of the drain tank WT, is formed so as to form a drain channel 36 that partially passes through the inclined plate floating body 10 . The outlet of the drainage channel 36 is the drainage port 11 provided in the inclined plate 5 described above. Therefore, through the drain port 11, water in the drain tank WT can be discharged to the outside environment by the action of the check valve 12, but water cannot flow in from the outside environment. The cover plate of the check valve 12 is made sufficiently large relative to the size of the drain port 11 so that the light from the outside of the floating body does not enter the inside of the floating body as much as possible, and the opening and closing does not open too much. . As a means for preventing light from the outside of the floating body for power generation 1 from entering the inside of the floating body for power generation 1 as much as possible, the direction of the drainage channel 36 may be devised.

Above the vertical water intake pipe 7, the water intake pump 8 is provided. A drive shaft 9 of the water intake pump 8 extends into the operator's cab 2 along the vertical center line 2c of the apparatus. A drive motor 37 connected to the upper end of the drive shaft 9 is arranged in the cab 2 . The drive shaft 9 is inserted through the protective tube 38 . Furthermore, a stay duct 39 is provided on the outer circumference of the protective tube 38 . These are all arranged concentrically along the vertical center line 2c of the device. The vertical centerline 2c is also the centerline of the vertical water intake pipe 7 . In addition, the stay duct 39 also serves as a support for supporting the operator's cab 2 and the like, and is an important structural member of the floating body 1 for power generation on the water.

Above the main tank MT, the cover 3 is provided to prevent water overtopping the inclined plate 5 from entering. Moreover, as shown in FIG. 3, the cover plate of each cover 3 is formed by laying a removable raised floor 50 in a sector shape. As a result, maintenance of the mechanical devices in the main tank MT, and cleaning, repair, replacement, etc. of the main tank MT in the event of adhesion of organisms, contamination, breakage, etc., can be performed relatively easily.

FIG. 12 is an explanatory diagram showing an overview of circular orbital motion of water particles when waves are generated in the ocean. This figure is a basic explanatory diagram of an amplitude wave, which is mostly published in literatures such as general marine civil engineering. As shown in FIG. 12, the water particles basically follow an elliptical trajectory 47, the upward arrow 48 is the flow of the circular orbital motion of the water particles as the crest of the wave comes, and the downward arrow 49 shows the flow of circular orbital motion of water particles when the wave trough comes.

Therefore, when facing upward, the water in the lower part of the device is fed into the main tank MT through the water intake port 13 . However, at this time, a large amount of deep water (bottom water) ST continuously pumped up from the lower layer fills the outside of the apparatus A on the upstream side of the water intake 13 provided in the bottom plate 6 of the main tank MT. First, this water is sent from the water intake 13 into the main tank MT. At this time, although it depends on design conditions, not only the deep water (bottom water) ST is taken in, but also the surface water in the vicinity of the bottom plate 6 is taken in.

In addition, when the boat is facing downward, the trough of the wave appears on the water surface, and a water level difference occurs between the water level when facing upward and the water level when facing downward. Since the water level of the water taken into the main tank MT when facing upward is higher, this water flows through the communication port 16 into the drain tank WT, and further through the drain ports 11, 27, and 28 provided above and below the drain tank WT. drained. Considering seasonality, biological resource production status, power generation efficiency, etc., the drainage from the drain outlets 27 and 28 should be stopped by locking the check valves 29 and 30, or the flow rate may be restricted (check valve opening/closing limit).

In addition, if the size of the floating power generating floating body 1 is set so that the circular orbital motion of the water particles of the wave simultaneously occurs in both the upward arrow 48 and the downward arrow 49 below the floating power generating floating body 1, then the floating power generating floating body 1 is offset in the vertical direction. Therefore, the water power generation floating body 1 does not move so much up and down. Therefore, if the water intake 13 and the water discharge ports 27, 28 and 11 are effectively used here, the wave power generation efficiency can be greatly increased.

As shown in FIG. 1, a gutter-shaped return plate 46 is provided at the lower edge of the inclined plate 5 . The return plate 46 prevents the deep cold water drained from the drain port 11 from flowing down along the upper surface of the inclined plate 5 and immediately reaching the lower layers of the ocean. The deep cold water drained from the drain port 11 is returned by the return plate 46, so that it is repeatedly mixed with the surface warm water of the ocean on the upper surface of the inclined plate to adjust the density.

At this time, the deep-sea water ST pumped up from the lower part by the vertical water intake pipe 7 enters from below the apparatus around the water intake 13 when passing through the water intake 13, the main tank MT, the communication port 16, the drainage tank WT, and the like. Since the water is mixed with the surface water near the surface layer, a large difference in temperature and density does not occur.

FIG. 3 is a view taken along the line XX in FIG. 1 and shows the water power generation floating body 1 in a plan view. As shown in FIG. 3, the water power generating floating body 1 according to the present embodiment has a substantially regular octagon shape in plan view. This shape is merely an example, and other polygons such as a regular dodecagon or a circle may be used. In this figure, the entire circumference of 360 degrees is divided into 8 equal parts, and the converging floating bodies 4 are arranged at the reference positions of each of the 8 equal parts. An inclined plate 5 and an inclined plate floating body 10 are provided between the convergent floating bodies 4, and when the entire circumference is connected, it becomes a substantially regular octagon. At the center of the water power generation floating body 1, the drive shaft 9 of the water intake pump 8, the protective pipe 38, and the stay duct 39 are arranged concentrically.

A water wheel rotating shaft 18 is connected to a water wheel 17 provided at the bottom of the main tank MT. The water wheel rotating shaft 18 extends toward the operator's cab 2 . The water wheel rotating shaft 18 is inserted through a protective tube 20 , and the protective tube 20 is inserted through a stay duct 22 . The water wheel rotating shaft 18, the protective tube 20, and the stay duct 22 are arranged concentrically. The water turbines 17 configured in this manner are arranged at four locations around the entire periphery of the floating body.

A steel partition frame is provided from the inner contour line of the converging floating body 4 toward the center line of the protection pipe 38 and the stay duct 39 at the center of the device. The inside of this partition frame is defined as a structural floor 21, and the stay duct 35 of the converging floating body 4, the stay duct 22 of the structural floor, and the stay duct 39 of the center of the apparatus are arranged substantially on a straight line, and vice versa. It extends symmetrically on both sides in the same way, and has a structure that combines vertical and horizontal crosshairs. As a result, even if the water power generation floating body 1 shakes during a typhoon or a storm, the structure is hard to be damaged.

The state ducts 35 and 22 are arranged in a cross shape in four directions with the stay duct 39 at the center, and serve as a floating body strength main member for supporting the floating power generation floating body 1, the operator's cab 2, the wind turbine tower, and the like. In addition, as a ventilation path for intake and exhaust, other rotating shafts, protective tubes such as wire ropes, etc. are placed and inserted concentrically on the tube to achieve a wide variety of purposes at the same time.

A raised floor 50 is provided on the upper portion of the main tank MT sandwiched between the four structural floors 21 described above. Therefore, the upper portion of the main tank MT is entirely covered with one of the covers, and the interior of the main tank MT is in a dark room state. Therefore, the deep water (bottom water) ST pumped up from the lower layer of the ocean passes through the vertical water intake pipe 7 and is sent into the main tank MT in the dark room without being exposed to light from the lower layer. Therefore, photosynthesis does not occur in deep water. At this time, light enters from below the device while the check valves 14, 12, 29, and 30 provided at the water intake port 13 and the water discharge ports 11, 27, and 28 are opened and closed. In addition, since the amount of light is small overall, it does not pose a big problem.

The drainage channels 36, drainage ports 11, and check valves 12 provided in the inclined plate 5 and the inclined plate floating body 10 are arranged at eight locations along the entire circumference of the floating body. In such a state, the check valve 12 is closed on the wave arrival side and opened on the wave passage side to drain the water in the drain tank WT no matter which direction the wave comes from. Therefore, when looking at the entire circumference of the floating body for power generation 1, some check valve 12 is always closed, but another check valve 12 is open. As a result, the water flow is rectified from the perspective of the apparatus as a whole, and the flow is stable to some extent, so the drainage efficiency is good.

FIG. 4 is a view taken along the line YY in FIG. 1 and shows the layout of the water intake areas in the bottom view of the water power generating floating body 1. As shown in FIG. As shown in FIG. 4, eight converging floating bodies 4 are equally divided along the reference line that divides the water power generation floating body 1 into eight equal parts. It is provided and constitutes a substantially regular octagonal water power generation floating body 1 .

A vertical water intake pipe 7 is provided at the center of the floating power generation floating body 1, and the horizontal reference line K of the converging floating body 4 is assumed in the horizontal direction in FIG. Assuming a 90° reference line K' in the intersecting vertical direction, a convergent floating body 4 is provided on each of them in the same manner as described above. A communication port 16 and a water wheel 17 are provided approximately at the center of the inner contour line of the convergent floating body 4 and the vertical water intake pipe 7 .

Assuming 45-degree direction reference lines L and L' subdivided in a direction different from the horizontal and vertical direction reference lines K and K' by approximately 45 degrees, similar to the above, from the vertical water intake pipe 7, under substantially the same conditions A converging floating body 4 is placed. A water intake 13 and a check valve 14 are arranged on the center line of the converging floating body 4 and near the inner contour line of the converging floating body 4. - 特許庁A nozzle 15 a from the vertical water intake pipe 7 is provided around the upstream side of the water intake port 13 . Deep water (bottom water) ST pumped up from the vertical water intake pipe 7 is discharged from the nozzle 15a to the upstream periphery of the water intake 13, and the upstream periphery is simply filled with the deep water (bottom water) ST. Therefore, deep water (bottom water) ST is fed into the main tank MT from below the floating body by circular orbital motion of water particles of waves.

At this time, the four divided areas sandwiched between the horizontal and vertical reference lines K and K' that intersect at 90 degrees over the entire circumference of the floating body for power generation on the water 1 are defined as intake water absorbing areas. If the entire circumference of the floating body for power generation on the water 1 is divided into four equal parts, it will be a fan-shaped range surrounded by braces on the outside of the maximum outline on the drawing, and the division codes a, b, c, and d will be attached. Therefore, the water intakes 13 are arranged on the oblique reference lines L, L' of the 45-degree intersection, which are intermediate lines between the horizontal and vertical reference lines K, K' of the 90-degree intersection. However, the water intakes 13 are arranged substantially in the center of the water intake area division codes a, b, c, and d, respectively.

In this state, the deep water taken and retained in each section and the surface water in the vicinity of the bottom plate 6 are lifted from below the floating power generation floating body 1 during the upward circular orbital motion of water particles of waves. Water is sent into the main tank MT by pressure. At this time, since the actual waves on the ocean progress with time, in the ranges with fan-shaped division codes a, b, c, and d enclosed in parentheses in each of the water intake areas described above In operation, the conditions are different for each, and there are areas where water is being taken and areas where it is stopped and water is not being taken.

FIG. 5 is a ZZ view in FIG. 1, and the division codes a, b, c, and d attached to the fan-shaped range surrounded by braces as in FIG. 4 indicate the arrangement of the water intake area is shown. On the other hand, the division codes e, f, g, and h attached to the portions surrounded by braces indicate the arrangement of the drainage sharing areas. 4, the communication port 16, the water wheel 17, and the drain port 27, check valve 29, drain port 28, check valve 30, drain port 11, check valve For the valves 12 and the like, assuming that child numbers are assigned for each division of the drainage area, provisionally, communication port 16e, water wheel 17e, drainage port 27e, check valve 29e, drainage port 28e, check valve 30e, drainage port 11e, Assume check valve 12e.

Depending on the operating conditions, the drain ports 27e and 28e may be closed and water may be drained from the drain port 11e provided on the inclined plate 5. FIG. A total of two drain ports 11e are provided, one on each side of the drain port 27e. Hereinafter, the same applies to the division codes f, g, and h of the drainage sharing areas attached to the fan-shaped portions. Although four drain tanks WT are shown as an example, actually all of them are connected and connected in the vicinity of the vertical water intake pipe 7 in the central part of the apparatus. As a result, water can freely flow back and forth in each of the drain tanks WT, so that each individual operation can be freely performed.

Next, in FIG. 5, the bottom plate 6 is also subdivided into four sections corresponding to the division codes a, b, c, and d of the above-described water intake areas. Even in each of the fan-shaped divisions of the water intake area and the drainage area, the water enclosing walls and guide walls cannot be constructed without providing some kind of aggregate in terms of the structure of the apparatus.

As an example, in the fan-shaped water intake area a section, in the fan aggregate on the polygonal line, the water intake 13a near the center of the floating body and the check valve 14a are detoured from a1 on the circumference, and further a1 on the circumference From a2 on the circumference, bypassing the water intake 13a and check valve 14a near the center of the floating body until returning to a2 on the circumference, from a3 on the circumference to the water intake near the center of the floating body 13a, bypassing the check valve 14a, and further returning to a3 on the circumference, from a4 on the circumference, bypassing the water intake 13a near the center of the floating body, the check valve 14a, and further to a4 on the circumference Until it returns, it bypasses the water intake 13a and the check valve 14a near the center from a5 on the circumference, and further returns from a6 on the circumference to the water intake 13a near the center of the floating body, Bypassing the check valve 14a and further returning to a6 on the circumference is defined as one section, and hereinafter similarly defined as section b, section c, and section d.

Since the surrounding walls and guide walls are strong walls, the polygonal fan aggregates (a1 to a6, b1 to b6, c1 to c6, d1 to d6) shown as examples above are used for the sake of simplification of the drawings. Although the aggregate is indicated by a tubular circle mark, it is not limited to a tubular shape, and may be of various shapes such as flat steel, L-shaped steel, channel steel, etc., as long as the role of the aggregate can be fulfilled.

FIG. 6 is a developed view of the portion viewed from the line VV in FIGS. 1 and 5. FIG. As shown in FIG. 6, the bottom plate 6 of the main tank MT is provided with, as an example, a check valve 14c at the water intake 13c. is repeatedly opened and closed. As a result, the water outside the bottom plate 6 is taken into the main tank MT. At this time, the rear surface of surrounding walls 54h and 54g of the drain tank WTh or WTg, which will be described later, guides water intake at the water intake port 13c, and this rear surface serves as a guide wall 55c.

FIG. 7 is a developed view of the portion viewed from the line WW in FIGS. 1 and 5. FIG. As shown in FIG. 7, the bottom plate 6 of the main tank MT is provided with a communication port 16g as an example. The communication port 16g communicates with a drain tank WTg provided below the bottom plate 6, and is provided with a water wheel 17g. A shaft coupling 24 for the rotating shaft 18 of the water wheel 17g is provided directly above the water wheel 17g. At the time of maintenance or the like, the structure is such that the rotary shaft 18 can be separated here.

In drawing the surrounding wall 54g of the drain tank WTg, the distance downward from the bottom surface of the bottom plate 6 of the main tank MT and the distance away from the center line of the communication port 16g are picked up from FIGS. FIG. 7 is a diagram obtained by pasting the surrounding wall 54g and the guide walls 55b and 55c of the drain tank WTg to the drawing. The same applies to subscripts e, f, and h below.

8 is a cross-sectional view taken along line RR in FIG. 7. FIG. 9 is a cross-sectional view taken along line QQ in FIG. 8. FIG. In FIG. 9, if the horizontal and vertical reference lines K, K' described with reference to FIGS. 4 and 5 and L, L' intersecting these at 45° are arranged, the drain tank WTh can be placed on the vertical reference line K. , WTf are arranged, and the drain tanks WTe, WTg are arranged on the vertical reference line K′. Therefore, the above-described fan aggregates a3 to d3 are present outside the vertical water intake pipe 7 centered on the center line of the artificial upwelling generator A, and these portions WTe, WTf, WTg, and WTh communicate with each other at a portion 57. are in communication with each other.

Here, the surrounding wall and the guide wall of the drainage tank WT are formed into an uneven wavy shape, and the surrounding wall 54 of the drainage tank WT and the guide wall 55 of the water intake port are used together on both sides of the single wall. gets better. In addition, the combination of both walls and the uneven phenomenon due to the waving phenomenon, the lifting force due to the upward circular orbital movement of the water particles of the wave from the bottom of the device and the upward force at each place hit the curve of the uneven wall, and the repulsive force However, due to the difference in angle at each location, the scattered reflection force scatters in the radial direction, and the repulsive force between the target wall surfaces immediately adjacent to each other is canceled. pressure is reduced.

Moreover, as shown in FIGS. 1 and 2, a skirt 56 is provided below the water power generation floating body 1 . If the skirt 56 is suspended to a large extent, the regular circular orbital motion of the water particles in the wave is destroyed to some extent when the circular orbital motion of the water particles outside the skirt 56 enters the skirt 56 due to the advance of the wave. the pressing force decreases. As a result, although the wave power generation efficiency is reduced, the vertical movement of the floating body is reduced, so the wind power generation efficiency is improved.

FIG. 10 is a vertical cross-sectional view showing the light shielding means in the stay duct (column) 39 at the T portion of FIG. 11 is a cross-sectional view taken along the line UU of FIG. 10. FIG. As shown in FIGS. 10 and 11, the protective tube 38 is inserted through the central portion of the conduit 51 inside the stay duct 39 . Furthermore, the rotating shaft 9 is inserted through the protective tube 38 . Further, the pipeline 51 has a function of an air intake/exhaust path 52 in the main tank MT.

A helical spiral plate 45a is fixed to the inner surface of the stay duct 39 by welding or the like in the conduit 51 between the stay duct 39 and the protective tube 38 . Between the inner diameter of the spiral plate 45a and the outer wall of the protective tube 38, a slight gap 38a is provided. This allows the protective tube 38 to move freely inside the spiral plate 45a. However, it is preferable to keep the gap 38a as small as possible in order to serve as a light blocking means.

In the stay duct 39, a helical spiral plate 45a is provided from the middle of the pipeline 51. As shown in FIG. The spiral plate 45a is a twisted flat plate, and is a curved plate with a different angle depending on where it is arranged. Even if a light beam (light) 53 enters the pipeline 51 from the upper air intake/exhaust port 23 of the stay duct (pillar) 39 straight downward toward the main tank MT, the winding spiral plate 45a prevents the light beam from entering. is refraction-blocked to prevent light rays from reaching the main tank MT. Therefore, for the spiral plate 45a, it is necessary to select a material, apply black coating, or the like as measures to reduce light reflection. The spiral plate 45b, which is the light shielding means in the stay duct 22, has the same configuration and function as the spiral plate 45a.

On the other hand, since the space between the stay duct 39 and the protection pipe 38 functions as the air intake/exhaust passage 52, the air in the main tank MT flows through the air intake/exhaust passage 52 as water is taken in and out of the main tank MT due to the wave motion outside the device. Repeat the back-and-forth flow. By designing the intake/exhaust passage 52 so that the flow speed of the air has some leeway, the resistance of the twisted plate of the spiral plate 45a does not impede the flow of air. A portion between the stay duct 22 and the protective tube 20 described above also has the same configuration and function as the intake/exhaust passage 52 .

FIG. 13 is a front view schematically showing the whole artificial upwelling generator A' according to the second embodiment of the present invention. FIG. 14 is a plan view schematically showing the entire artificial upwelling generator A'. The artificial upwelling generator A' is obtained by adding an ocean current generator (water current generator) 71 to the artificial upwelling generator A according to the first embodiment.

As shown in FIG. 13, the artificial upwelling current generator A' generates offshore wind power using a windmill 66 on the sea. Wave power generation is performed by the wave power generation device 70 in the vicinity of the water surface. Moreover, ocean current power generation is performed by the ocean current generator 71 under the water surface. The electric power generated by these is each collected in the operator's cab 2 on the upper part of the floating body.

Also, a small part of the electric power collected in the operator's cab 2 is consumed as power for pumping up deep water (bottom water) ST by the artificial upwelling generator A'. Note that the structure itself of the ocean current generator 71 that generates electricity by the flow of ocean currents and tides is as disclosed in Japanese Patent Application Laid-Open No. 2016-114057 (Patent Document 2) by the same applicant as the present application, and is not the gist of the present invention. Therefore, detailed description is omitted.

FIG. 15 is a front view schematically showing an entirety of an artificial upwelling generator A″ according to a third embodiment of the present invention. 1, it is configured to be able to respond to the free direction of ocean currents and tidal currents. In this artificial upwelling current generator A", the structure itself that can correspond to the free flow direction of ocean currents and tides is also as disclosed in Japanese Patent Application Laid-Open No. 2016-114057 (Patent Document 2) by the same applicant as the present application. However, the basic configuration and operation will be briefly described below.

As shown in FIG. 2, in the above-described artificial upwelling current generator A, a chain attachment portion 41 is secured below the water power generating floating body 1 in order to moor the water power generating floating body 1 . The upper end of the chain 63 is attached to the chain attachment portion 41 , and the lower end of the chain 63 is connected to the submarine anchor 62 . Therefore, since the water power generation floating body 1 and the vertical water intake pipe 7 are moored by the chains 63, the water power generation floating body 1 can move or rotate flexibly within the range of play in which the chains 63 can be deformed. Basically, it was not a freely rotatable configuration. The same applies to the artificial upwelling generator A' shown in FIG.

On the other hand, as shown in FIG. 15, in the artificial upwelling current generator A″ according to the third embodiment, the chain mounting portion 42 is fixed above the vertical water intake pipe 7, and the floating body 1 itself The chain attachment portion 42 is not fixed to the surface power generation floating body 1. And the water power generation floating body 1 is freely rotatable with respect to the vertical water intake pipe 7. Therefore, the ocean current generator 71 attached to the water power generation floating body 1 is It is naturally placed in a position such that it is swept downstream by the ocean current SF.

When the direction of the ocean current SF changes, the ocean current generator 71 turns around the vertical center line 2c, which is the axial center of the vertical water intake pipe 7, and changes its orientation. Thus, the floating body for power generation 1 and the ocean current generator 71 are configured to be freely rotatable around the vertical center line 2c of the artificial upwelling generator A″.

FIG. 16 is an overall configuration diagram of a water power generation floating body and an artificial upwelling current generator B provided with the water power generation floating body according to a fourth embodiment of the present invention. FIG. 17 is a plan view thereof.
The major difference between the first to third embodiments and the fourth embodiment is that, in the first to third embodiments, the wave power generation device 70 is mounted on the water power generation floating body 1. Therefore, the device has a very complicated structure. However, since there is no wave power generation device 70 in the fourth embodiment, the structure of the device is greatly simplified. For example, in the first to third embodiments, the convergent floating bodies 4 and the inclined plate floating bodies 10 are alternately connected, but in the fourth embodiment, the cylindrical divided floating bodies 75 are simply connected. It has become.

Also in the ballast tank portion in the central part of the apparatus, the first to third embodiments are two-tiered with the drain tank WT below the main tank MT. However, in the fourth embodiment, since there is no wave power generation device 70, the ballast tank BTa is simplified to have only one ballast tank that provides buoyancy. However, depending on the sea area such as the installation location, the sea area, and the conditions of the sea conditions, it may be more economical without the wave power generation device 70 and the cost of power generation may be reduced. Therefore, descriptions other than those described with reference to FIG. 15 are substantially the same as the descriptions of the first to third embodiments, and the description thereof is omitted.

FIG. 18 is an enlarged vertical cross-sectional view of the deep water (bottom water) discharge portion of the artificial upwelling generator B in the fourth embodiment of FIG. The ballast tank BTa is a buoyancy chamber, and is structured so that workers can enter and exit during maintenance. For this reason, there are entrances for workers, entrances for equipment, piping for air and ballast water, blowers, water, and drains. A discharge tank 76 is provided at the upper central portion of the ballast tank BTa. The discharge tank 76 is composed of a discharge tank bottom portion 76a, a discharge tank upper portion 76b, and a discharge tank conical portion 76c. Deep water (bottom water) ST pumped up by 8a (shown in FIG. 16) is discharged to the discharge tank bottom portion 76a through the nozzle 15c.

The discharged deep water (bottom water) ST is discharged onto the inclined upper surface of the ballast tank upper inclined wall BTb via the upper discharge tank 76b of the discharge tank 76 and the discharge duct 76d. At this time, the discharge duct 76d is provided with a bent tube portion or the like, and shielding means is also taken to prevent light rays from entering from the outside as much as possible. In addition, a discharge port grid 76e is provided at the discharge port of the discharge duct 76d to mix and disperse the pumped deep water (bottom water) ST with the upper water. The structure is difficult to enter. Further, although it has already been calculated that a certain amount of deposits are attached to the discharge port grid 76e, the structure is also such that light is less likely to enter the discharge duct 76d.

19 is a plan view taken along line SS in FIG. 18. FIG. Here, the discharge duct 76d is arranged around the entire circumference of the vertical water intake pipe 7a.

FIG. 20 is an overall configuration diagram of an artificial upwelling generator B' according to the fifth embodiment. This artificial upwelling generator B' is obtained by adding an ocean current generator 71a to the artificial upwelling generator B according to the fourth embodiment. FIG. 21 is a plan view of an artificial upwelling generator B' according to the fifth embodiment. Therefore, the description that follows is substantially the same as what has been described so far, and will not be repeated.

FIG. 22 is an artificial upwelling according to the sixth embodiment in which the floating body for power generation on the water according to the fifth embodiment of the present invention is equipped with a floating body for power generation that can respond to the free flow direction of ocean currents and tidal currents. FIG. 2 is an overall configuration diagram of a flow generating device B″. Since the content of the invention is substantially the same as that described so far, and overlaps with the description related to FIG. 15, the description thereof is omitted.

Therefore, the present invention has a great effect on human life because it extends to the field of power generators, the cultivation of marine phytoplankton and zooplankton beyond the boundaries of the power generator field, the production of biological resources such as fish and shellfish, and the like. In addition, since there are significant advantages in terms of efficiency, safety, stability, maintenance, inspection maintainability, economy, etc., a significant reduction in power generation costs can be expected.

Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration is not limited to the above-described embodiments, and the present invention may be modified or added without departing from the gist of the present invention. Included in the invention.
For example, although the plurality of waste water tanks WT is illustrated as four tanks, the number is not limited to that. Also, it may be one. Although it is preferable that the number of generators associated with each drain tank WT and the associated components is the same as that of the drain tank WT, the number is not limited to the same number.

The floating body and the artificial upwelling current generator provided with the floating body according to the present invention can be widely applied without being limited to power generators that utilize offshore wind power, wave power, and ocean current energy. Therefore, it can be widely used in the field of utilizing flowing water energy such as tidal currents that reverse every 6 hours, tidal power generation, or river water power generation.
