Description

The present invention relates to a floating body that includes a generator and generates power by floating on water, and an artificial upwelling flow generator including the floating body.
In particular, the present invention is one that generates wave power by vertical movement of waves (circular orbital motion of water particles), or includes the floating body, or generates power using ocean energy by ocean current, tidal current, or the like, or includes the floating body. The present invention relates to the field of energy conversion such as offshore wind power generation using offshore wind turbines mounted on the floating body.

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

  Conventionally, global warming and various destruction of the global environment have been screamed, but these problems have become increasingly serious in recent years. These are also closely related to the problem of carbon dioxide emissions from the use of fossil energy resources. The fossil energy resource has a quantitative problem of the energy resource itself such as a depletion problem. Concerning these problems, energy saving and resource saving are screamed, and the early introduction and early commercialization of clean natural energy that does not emit carbon dioxide has become a global issue.

  In addition, electric energy is supplied by nuclear power generation. Problems related to the use of nuclear power include radioactivity that can occur due to aging of nuclear reactors such as nuclear power plants, earthquakes, tsunamis, natural disasters, human disasters, etc. There is a leakage accident. As is well known, radioactivity has a major negative impact on the ecological environment, and when a radioactivity leak accident occurs, the adverse impact on the living environment of local residents is extremely large, as can be seen from examples of the Fukushima nuclear accident. The damage can be serious.

  In addition, onshore wind energy utilization devices in Japan have pollution problems such as low-frequency noise problems as the devices become larger. In Japan, where the land area is small and the area occupied by the mountainous area is large, it is difficult to establish a large-scale new location on land, but it is necessary to promote new energy development as soon as possible. . Thus, there is an urgent need for significant improvement and promotion of conventional devices in terms of safety, stability, efficiency, maintainability, etc. while taking into account noise pollution and environmental pollution problems.

  The earth is 71% of the surface area of the sea, and Japan is an oceanic country surrounded by the sea on all sides. In addition, Japan is one of the world's largest powers, including the area of territorial waters and exclusive economic zones. Therefore, by effectively utilizing the sea and installing floating, landing, or offshore wind energy utilization devices on the ocean, it is possible not only to solve pollution problems such as low-frequency noise but also to increase the scale. Become. For this reason, it is also possible to make wind energy sufficiently useful as an alternative energy for nuclear power generation.

  In addition, the development of wind energy utilization devices on remote islands, etc., enables residence on uninhabited islands where people can't live, whether on land or offshore, such as the Senkaku Islands and the Ogasawara Islands. In addition, in order to increase the possibility of these islands as fishing grounds and tourist destinations, further improve the life and convenience of islanders by saving oil transportation costs and energy resources on remote islands and expanding tourism, fisheries, etc. It is beneficial to use the sea effectively to improve or to promote wide-area activities of the people and the decentralization of urban-intensive population.

  There are many ocean energy resources such as wave energy, wind power, sunlight, ocean currents, and tides in the ocean. Therefore, an apparatus (see Patent Document 1) in which these are mounted on a single floating body can efficiently use energy at low cost, safely and efficiently, and can be used effectively as a stable energy source by combining various energy sources with different properties. Development of generators by diversifying energy is desired.

  In addition, 4.6 billion years have passed since the birth of the Earth, and there are infinite amounts of nutrients such as nitrogen and phosphorus flowing from the land on the ocean floor. By using a device that uses both a floating support shaft and a vertical intake pipe related to the present invention (refer to Patent Document 2), deep water (bottom water) in the lower layer is pumped up to the sea surface, and phytoplankton due to artificial upwelling flow is increased. The aquaculture and propagation of marine food resources spread to the marine ecosystem, bioenvironment, and bioresource production fields of the ocean beyond the electrical technical field such as generators and the mechanical and structural technical fields. Therefore, it is necessary socially and economically to develop these as soon as possible. As the first step, the development of the most familiar wave power generation, ocean current, tidal current, offshore wind power, and offshore wind energy utilization device is required. Urgently desired.

Japanese Patent No. 5688764 JP 2016-1114057 A

In the patent document 1, the applicant of the present application has proposed a wave energy utilization device as a device that generates water using wave power by providing a water intake and a drain port on an inclined surface of a floating body that floats on the water surface. However, in the floating body that takes in the wave power (water) in the wave power generator and the configuration of the apparatus, it has been desired to further improve and improve the mechanism.

As a result, more phytoplankton will be proliferated, resulting in the promotion of zooplankton growth that prey on it, and in order to increase the deposits on the device due to these plankton, the device must be improved There was a problem of not becoming.

  In particular, in floating wave power and offshore wind energy utilization equipment, etc., the mechanism has been simplified as it is put into practical use and the scale of the equipment is increased, and the equipment is manufactured as much as possible at a land factory such as a dock, and assembled and transported locally. The simplification of installation, etc., leading to cost reductions in all of the maintenance costs and operation costs, etc., leads to a reduction in power generation costs. For this reason, there was a problem that it was necessary to reduce field work on the ocean as much as possible.

  Also, when transporting, installing, towing, etc., offshore wind energy utilization devices, etc., by lowering the center of gravity using ballast water injection etc. to the self-floating body, and making it a stable device, the arrival of unexpected low pressure, In the event of a gust, it was necessary to be able to respond easily and to keep the device safe.

  The present invention has been made by paying attention to such problems and problems of the conventional technology.

Similarly, the protection tube 20 is also connected using a connecting metal 25 just above the water wheel 17 so that the water wheel 17 and the protection tube 20 can be easily separated during maintenance. Further, at the time of maintenance, the generator 19, the water turbine rotating shaft 18, and the protective tube 20 are configured to be easily lifted upward using a wire, a rope 26, or the like.

  The water inside the main tank MT is configured to flow inside the drainage tank WT. Drain ports 27 and 28 are provided below the drain 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 at the time of drainage for draining the water inside the drainage tank WT to the outside of the floating body and to be closed at the time of backflow.

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

  Hooks (not shown) to which wire ropes 31, 32, etc. are connected are provided at the upper portions of the check valves 29, 30 at the drain outlets 27, 28, respectively, and one ends of the wire ropes 31, 32 are connected to this. It is tied. The other ends of the wire ropes 31 and 32 are led to a pulley provided on the ceiling of the cab 2 to pull, clamp and lock the check valves 29 and 30 for artificial opening and closing operations. Etc. can be easily performed. The wire ropes 31 and 32 are inserted into the protection tubes 33 and 34 and are protected by the protection tubes 33 and 34. Further, where the wire ropes 31 and 32 are bent and arranged, the wire ropes 31 and 32 are guided using a bender pipe or the like.

  The protective tube 33 extends through the convergent levitation body 4 to the cab 2. A stay duct 35 is provided from the top of the convergent levitation body 4 to the place where the protective tube 33 penetrates the floor of the cab 2. The stay duct 35 also serves as a support column, and also serves as a ventilation path and a main structural column in the convergent levitation body 4.

  Although the bottom plate 6 of the main tank MT is also an upper plate of the drainage tank WT, a part of the bottom plate 6 is formed as a drainage passage 36 that passes through the inclined plate floating body 10. The outlet of the drainage channel 36 is a drainage port 11 provided in the inclined plate 5 described above. Therefore, although the water in the drainage tank WT can be discharged to the external environment from the drainage port 11 by the action of the check valve 12, the inflow of water from the external environment cannot be performed. The cover plate of the check valve 12 is sufficiently large with respect to the size of the drain port 11 so that light from the outside of the floating body does not enter the floating body as much as possible, and the opening / closing is not opened so much. . The direction of the drainage channel 36 may be devised as a means for preventing light from the outside of the hydroelectric floating body 1 from entering the hydroelectric floating body 1 as much as possible.

  The above-described water intake pump 8 is provided at the upper part of the vertical water intake pipe 7. The drive shaft 9 of the water intake pump 8 extends into the 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 disposed in the cab 2. The drive shaft 9 is inserted through the protective tube 38. Further, a stay duct 39 is provided on the outer periphery of the protective tube 38. These are all provided concentrically along the vertical center line 2c of the apparatus. The vertical center line 2 c is also the center line of the vertical intake pipe 7. The stay duct 39 also serves as a support column that supports the cab 2 and the like, and is an important structural material of the floating power generation floating body 1.

  Above the main tank MT, the cover 3 for preventing the intrusion of water that has waved over the inclined plate 5 is provided. Moreover, as shown in FIG. 3, the cover plate of each cover 3 is formed by spreading a removable raised floor 50 in a fan shape. Thereby, cleaning, repair, replacement, etc. can be performed relatively easily during maintenance of the mechanical device in the main tank MT, biofouling in the main tank MT, dirt, damage or the like.

  FIG. 12 is an explanatory diagram showing an outline of circular orbital motion of water particles when waves are generated in the ocean. This figure is a basic explanatory view 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, and the upward arrow 48 indicates the flow of the circular orbital motion of the water particles when the wave mountain comes, and the downward arrow 49. Shows the flow of circular orbital motion of water particles when a wave valley comes.

  Therefore, when upward, the water below the apparatus is fed into the main tank MT from the water intake 13. However, at this time, deep water (bottom water) ST pumped continuously from the lower layer is filled in the upstream of the intake port 13 provided in the bottom plate 6 of the main tank MT. First, this water is fed from the water intake 13 into the main tank MT. At this time, although depending on the design conditions, only the deep water (bottom water) ST is not necessarily taken, and surface water near the bottom plate 6 is also taken in.

  Further, when it is downward, a wave trough comes on the water surface, and there is a difference in water level between the upward water level and the downward water level. Since the water taken into the main tank MT when facing upward has a higher water level, this water flows into the drainage tank WT through the communication port 16, and further from drainage ports 11, 27, 28 provided above and below the drainage tank WT. Drained. Considering seasonal, biological resource production status, power generation efficiency, etc., the drainage from the drainage ports 27, 28 locks the check valves 29, 30 to stop the flow or restrict the flow rate (checkback). Valve open / close restriction).

  Further, if the size of the hydroelectric floating body 1 is set so that the circular orbital motion of the water particles of the waves is generated simultaneously at both the upward arrow 48 and the downward arrow 49 below the hydroelectric floating body 1, the hydroelectric floating body The vertical direction is canceled out for the whole 1. Therefore, the hydroelectric floating body 1 does not have a large vertical movement. Therefore, if the intake port 13 and the drain ports 27, 28, and 11 are effectively used here, the wave power generation efficiency is greatly increased.

  As shown in FIG. 1, a return plate 46 formed in a bowl shape is disposed at the lower end edge of the inclined plate 5. The return plate 46 is for preventing the deep cold water drained from the drain port 11 from flowing down along the upper surface of the inclined plate 5 and immediately going to the ocean lower layer. 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 hot water of the ocean on the upper surface of the inclined plate to adjust the density.

  At this time, the deep water ST pumped from the lower layer by the vertical intake pipe 7 is mixed from below the apparatus around the intake port 13 when passing through the intake port 13, the main tank MT, the communication port 16, the drainage tank WT, and the like. Since it is mixed with the surface layer water near the surface layer, a very large temperature difference and density difference do not occur, but by remixing by the return plate 46, the temperature difference and density difference become smaller.

  FIG. 3 is a view taken along the line XX in FIG. 1 and shows the hydroelectric floating body 1 in plan view. As shown in FIG. 3, the hydroelectric floating body 1 according to the present embodiment has a substantially regular octagonal shape in plan view. This shape is merely an example, and may be another polygon such as a regular dodecagon or a circle. In this figure, the entire circumference 360 degrees is divided into eight equal parts, and the convergent levitation body 4 is arranged at the respective eight equal reference positions. An inclined plate 5 and an inclined plate floating body 10 are provided between the converging pontoon floating body 4 and the converging pontoon floating body 4. When the entire circumference is connected, it becomes a substantially regular octagon. A drive shaft 9, a protective tube 38, and a stay duct 39 of the water intake pump 8 are arranged concentrically at the center of the floating power generator 1.

  A water turbine rotating shaft 18 is connected to the water turbine 17 provided at the bottom of the main tank MT. The water turbine rotating shaft 18 extends toward the cab 2. The water turbine rotating shaft 18 is inserted through a protection tube 20, and the protection tube 20 is inserted through a stay duct 22. The turbine rotation shaft 18, the protective tube 20, and the stay duct 22 are arranged concentrically. The water turbine 17 configured in this manner is arranged at four locations on the entire circumference of the floating body.

  A steel partition frame is provided from the inner contour line of the converging levitation body 4 toward the protective tube 38 and the center line of the stay duct 39 in the center of the apparatus. The inside of the partition frame is a structural floor 21, and the above-described stay duct 35 of the converging levitation body 4, the stay duct 22 of the structural floor, and the stay duct 39 in the center of the apparatus are arranged on a substantially straight line, and vice versa. Similarly, the side is extended symmetrically and combined in a vertical and horizontal cross line. Thereby, even if the hydroelectric floating body 1 shakes at the time of a typhoon or a big load, it has a structure which is not easily damaged.

  Centering on the stay duct 39, the state ducts 35 and 22 are arranged so as to form a cross in four directions, and are used as the main strength of the floating body that supports the floating power generator 1, the cab 2, the windmill tower, and the like. Furthermore, as a ventilation path for intake and exhaust, another rotating shaft, a protective tube such as a wire rope, and the like are disposed concentrically on the tube, thereby achieving various purposes at the same time.

  A raised floor 50 is provided in the upper part of the main tank MT sandwiched between the four positions of the structural floor 21 described above. Therefore, the upper part of the main tank MT is all covered with any cover, and the inside of the main tank MT is in a dark room state. Therefore, the deep layer water (bottom layer water) ST pumped from the lower layer of the ocean passes through the vertical intake pipe 7 and is sent into the dark tank main tank MT without being filled with light from the lower layer. For this reason, photosynthesis in deep water is not performed. At this time, light enters from the lower side of the apparatus during the opening / closing operation of the check valves 14, 12, 29, and 30 provided at the water intake port 13 and the water discharge ports 11, 27, and 28, but the light that has come around from the water surface. In addition, since it is a small amount of light as a whole, it is not a big problem.

  The drainage channel 36, the drainage port 11, and the check valve 12 provided in the inclined plate 5 and the inclined plate floating body 10 are arranged at eight places over the entire circumference of the floating body. In this state, the check valve 12 closes on the wave arrival side, but opens on the wave passage side, and the water in the drain tank WT is drained, regardless of the direction from which the wave comes. Accordingly, when viewed all around the hydroelectric floating body 1, the check valve 12 somewhere is always closed, but another check valve 12 is opened somewhere. For this reason, the flow of water is rectified from the viewpoint of the overall apparatus, and the drainage efficiency is good because the flow is stable to some extent.

  FIG. 4 is a view taken in the direction of arrows YY in FIG. 1 and shows the arrangement of the moisture-bearing area in the bottom view of the hydroelectric floating body 1. As shown in FIG. 4, eight converging levitation bodies 4 are equally arranged along a reference line obtained by dividing the hydroelectric power generation body 1 into eight equal parts, and an inclined plate floating body 10 (see FIG. 3) is provided between each of them. A substantially regular octagonal hydroelectric floating body 1 is provided.

  A vertical intake pipe 7 is provided in the center of the floating body of the floating power generation body 1, and the horizontal reference line K of the converging float 4 is assumed in the horizontal direction in FIG. Assuming a 90 ° reference line K ′ also in the intersecting vertical direction, a converging levitation body 4 is provided in the same manner as described above. A communication port 16 and a water wheel 17 are provided at the center line of the inner contour line of the convergent levitation body 4 and the vertical 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 about 45 degrees, the vertical intake pipe 7 is used under the same conditions as described above. A convergent levitation body 4 is arranged. The water intake 13 and the check valve 14 are arranged on the center line of the convergent levitation body 4 and from the inner line of the convergent levitation body 4. In the vicinity of the upstream side of the intake port 13, a nozzle 15 a from the vertical intake pipe 7 is provided. Deep layer water (bottom layer water) ST pumped from the vertical intake pipe 7 is discharged from the nozzle 15a to the upstream side periphery of the intake port 13, and the upstream side region is simply filled with the deep layer water (bottom layer water) ST. For this reason, the deep layer water (bottom layer water) ST is sent into the main tank MT by the circular orbital motion of the water particles of the waves from below the floating body.

  At this time, a four-divided region sandwiched between the horizontal and vertical reference lines K and K ′ at the 90-degree crossing over the entire circumference of the hydroelectric floating body 1 is defined as a moisture bearing area. If the entire circumference of the hydroelectric floating body 1 is divided into four equal parts, it is set as a range in which division codes a, b, c, and d are formed in a fan shape surrounded by curly braces outside the maximum outer shape in the drawing. Therefore, the respective intakes 13 are arranged on the oblique reference lines L and L ′ intersecting at 45 degrees which are intermediate lines between the horizontal and vertical reference lines K and K ′ intersecting at 90 degrees. However, the intake port 13 is arranged in the approximate center of the intake area section codes a, b, c, and d.

  In such a state, the deep water collected and retained in each section and the surface water in the vicinity of the bottom plate 6 are lifted from the lower side of the hydroelectric floating body 1 when the circular orbital motion of the water particles of the wave is upward. Water is fed into the main tank MT by pressure. At this time, since the actual wave travels over time on the ocean, in the ranges marked with the sector-shaped division codes a, b, c, d enclosed in parentheses in each of the moisture intake areas described above. In operation, the conditions are different, and some areas are taking water, and some areas are stopped and not taking water.

  FIG. 5 is a view taken along the line ZZ in FIG. 1, and similarly to FIG. 4, the division codes a, b, c, and d attached to the fan-shaped range surrounded by curly braces are the arrangement of the moisture-bearing area. Is shown. On the other hand, the division codes e, f, g, and h attached to the portion surrounded by the braces on the outside indicate the arrangement of the drainage sharing area. In the following, in the reference numerals given in FIG. 4, as an example, the communication port 16 and the water wheel 17, and in FIG. 5, the drain port 27, the check valve 29, the drain port 28, the check valve 30, the drain port 11, the check In the valve 12 etc., assuming that a child number is taken for each division of the drainage sharing area, the communication port 16e, the water wheel 17e, the drainage port 27e, the check valve 29e, the drainage port 28e, the check valve 30e, the drainage port 11e, Assume a check valve 12e.

  Depending on the operating conditions, the drain outlets 27e and 28e may be closed and drained from the drain outlet 11e provided on the inclined plate 5. A total of two drain outlets 11e are provided on each side of the drain outlet 27e. Hereinafter, the same applies to the division codes f, g, and h of the drainage sharing area attached to the fan-shaped portion. However, although four drainage tanks WT are illustrated, in reality, all are connected in the vicinity of the vertical water intake pipe 7 in the center of the apparatus and are serialized. As a result, water can freely go back and forth in each drainage tank WT, so that each individual operation can be performed freely.

  Next, in FIG. 5, the bottom plate 6 is also subdivided into four parts, which correspond to the division codes a, b, c, and d of the respective moisture intake areas described above. Even in the division of each fan-shaped moisture collecting area and drainage sharing area, the water enclosure wall and the guide wall cannot actually be constructed as a structure unless some aggregate is provided in terms of the device structure.

  As an example, in the fan-shaped moisture intake area a section, in the fan frame on the broken line, the intake port 13a and the check valve 14a near the center of the floating body are bypassed from the a1 on the circumference, and further the a1 on the circumference Until the return to the circle, the intake port 13a and the check valve 14a in the vicinity of the center of the floating body are bypassed from the a2 on the circumference, and the intake port in the vicinity of the center of the floating body is returned from the a3 on the circumference until it returns to a2 on the circumference. 13a, bypass the check valve 14a, and further bypass the intake port 13a and the check valve 14a near the center of the floating body from a4 on the circumference until returning to a3 on the circumference, and further to a4 on the circumference Until returning, the water intake 13a near the center from the a5 on the circumference bypasses the check valve 14a, and further from the a6 on the circumference to the water intake 13a near the center of the floating body until returning to a5 on the circumference. Bypass the check valve 14a and return to a6 on the circumference As similarly b segment, c segment, and d classification below.

  Since the enclosure wall and the guide wall are strength walls, the polygonal fan frame materials (a1 to a6, b1 to b6, c1 to c6, and d1 to d6) shown as the above example are for simplifying the drawing. Although the aggregate is indicated by a tubular circle, the aggregate is not limited to a tubular shape, and various shapes such as a flat steel, an L-shaped steel, and a grooved steel can be used as long as they can fulfill the role of the aggregate.

  FIG. 6 is a development view of the part taken along the line VV in FIGS. 1 and 5. As shown in FIG. 6, the bottom plate 6 of the main tank MT is provided with a check valve 14 c at the water intake port 13 c as an example, and the check valve 14 c is repeatedly generated by repeating upward and downward movements due to the circular orbital motion of water waves. Is repeatedly opened and closed. Thereby, the water outside the bottom plate 6 is taken into the main tank MT. At this time, water intake is guided by the water intake port 13c on the back surface of the drainage tank WTh or the surrounding walls 54h, 54g of the WTg, which will be described later, and this back surface becomes the guide wall 55c.

  FIG. 7 is a development view of the site indicated by arrows WW in FIGS. 1 and 5. As shown in FIG. 7, a communication port 16g is provided as an example in the bottom plate 6 of the main tank MT. 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 joint 24 of the rotating shaft 18 of the water wheel 17g is provided immediately above the water wheel 17g. At the time of maintenance, etc., the rotary shaft 18 can be separated here.

  In drawing the enclosure wall 54g of the drain tank WTg, the distance from the bottom surface of the bottom plate 6 of the main tank MT to the lower side and the distance away from the center line of the communication port 16g are picked up from FIGS. FIG. 7 is a diagram in which the enclosure wall 54g of the drainage tank WTg and the guide walls 55b and 55c are pasted to the plot of FIG. The same applies to the subscripts e, f, and h.

  8 is a cross-sectional view taken along line RR in FIG. 9 is a cross-sectional view taken along line QQ in FIG. 9, if the horizontal and vertical reference lines K and K ′ described with reference to FIGS. 4 and 5 and L and L ′ intersecting these at 45 ° are arranged, the drainage tank WTh is placed on the vertical reference line K. , WTf, and drain tanks WTe, WTg are arranged on the vertical reference line K ′. Accordingly, the above-described fan frames a3 to d3 are provided outside the vertical intake pipe 7 centering on the center line of the artificial upwelling generator A, and these portions are connected to the communication part 57 by WTe, WTf, WTg and WTh, respectively. Communicate with

  By making the enclosure wall and the guide wall of the drainage tank WT into a corrugated corrugated shape, and using the enclosure wall 54 of the drainage tank WT and the guide wall 55 of the intake port together on both sides of the single wall, the economics of the apparatus Will be better. In addition, the unevenness phenomenon due to the combined use of both walls and the undulation phenomenon is caused by the upward pressure of the circular orbital motion of the water particles from the bottom of the device, and the upward force at each location hits the curve of the uneven wall, and the repulsive force However, due to the difference in angle at each location, the scattered reflection force is scattered in the radial direction and the repulsive force between adjacent target wall surfaces cancels each other, so that the pressing force exerted on the bottom surface of the hydroelectric floating body 1 is reduced. Pressure is reduced.

  As shown in FIGS. 1 and 2, a skirt 56 is provided below the hydroelectric floating body 1. When the skirt 56 is greatly suspended, the regular circular orbital motion of the water particles of the wave is destroyed to some extent when the circular orbital motion of the water particles outside the skirt 56 enters the skirt 56 by the progress of the wave. The pressing force decreases. For this reason, the wave power generation efficiency is reduced, but the vertical movement of the floating body is reduced, so that the wind power generation efficiency is improved.

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

  A spiral spiral plate 45 a is fixed to the inner surface of the stay duct 39 by welding or the like in the pipe line 51 between the stay duct 39 and the protective pipe 38. A slight gap 38 a is provided between the inner diameter of the spiral plate 45 a and the outer wall of the protective tube 38. Thereby, the protection tube 38 can move freely inside the spiral plate 45a. However, in order to fulfill the role of the light blocking means, it is preferable to keep the gap 38a as small as possible.

  In the stay duct 39, a spiral plate 45a having a spiral shape is provided in the middle of the pipeline 51. The spiral plate 45a is a plate with a twisted flat plate, and is a plate with a twisted shape with different angles for each placement location. Even if the light beam (light) 53 enters the pipe 51 from the upper intake / exhaust port 23 of the stay duct (support) 39 toward the main tank MT just below the spiral plate 45a, Is prevented from reaching the main tank MT. Therefore, the spiral plate 45a is required to select a material, apply black coating, or the like as a countermeasure for reducing light reflection. The spiral plate 45b, which is a 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 air in the main tank MT functions as the intake / exhaust passage 52 between the stay duct 39 and the protective pipe 38, the intake / exhaust passage 52 in the main tank MT is taken in and out by the wave outside the apparatus. Repeat the reciprocating flow. It should be noted that by designing the air flow velocity in the intake / exhaust passage 52 to allow a large space, the resistance of the spiral plate 45a does not hinder the air flow. The same structure and function as those of the intake / exhaust passage 52 are also provided between the stay duct 22 and the protective tube 20.

  FIG. 13: is a front view which shows roughly the whole artificial upwelling generator A 'concerning the 2nd Embodiment of this invention. FIG. 14 is a plan view schematically showing the whole artificial upwelling generator A ′. The artificial upwelling generator A 'is obtained by adding an ocean current generator (water generator) 71 to the artificial upwelling generator A according to the first embodiment.

  As shown in FIG. 13, the artificial upwelling generator A ′ performs offshore wind power generation by a windmill 66 at sea. In the vicinity of the water surface, wave power generation is performed by the wave power generator 70. Under the surface of the water, ocean current power is generated by the ocean current generator 71. The electric power generated by these is collected in the cab 2 above the floating body.

  A small part of the electric power collected in the cab 2 is consumed as power for pumping deep water (bottom water) ST by the artificial upwelling generator A '. In addition, the structure itself of the ocean current generator 71 that generates power by the flow of the ocean current / tidal current is as disclosed in Japanese Patent Application Laid-Open No. 2016-1114057 (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 the whole of the artificial upwelling generator A ″ according to the third embodiment of the present invention. The artificial upwelling generator A ″ is a hydroelectric floating body in the ocean. It is configured to be able to cope with the flow direction of free ocean current and tidal current for 1. In this artificial upwelling generator A ″, the structure itself that can correspond to the flow direction of free ocean currents and tidal currents is also disclosed in Japanese Patent Application Laid-Open No. 2016-114057 (Patent Document 2) by the same applicant as this application. However, the basic configuration and operation will be briefly described below.

  As shown in FIG. 2, in the above-described artificial upwelling generator A, the chain attachment portion 41 is fixed below the floating power generation floating body 1 in order to moor the floating power generation 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 seabed anchor 62. Accordingly, since the hydroelectric floating body 1 and the vertical intake pipe 7 are moored by the chain 63, the hydroelectric floating body 1 can be moved or rotated to some extent within the range of play in which the chain 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 generator A ″ according to the third embodiment, the chain attachment portion 42 is fixed above the vertical intake pipe 7, and the floating power generator 1 itself The chain attachment portion 42 is not fixed to the hydroelectric generator floating body 1. The hydroelectric floating body 1 can freely rotate with respect to the vertical intake pipe 7. Therefore, the ocean current generator 71 attached to the hydroelectric floating body 1 is It is naturally arranged at a position where it is caused to flow downstream by the ocean current SF.

  When the direction of the flow of the ocean current SF changes, the ocean current generator 71 turns around the vertical center line 2c, which is the axis of the vertical intake pipe 7, and changes its direction. Thus, the floating power generator 1 and the ocean current generator 71 are configured to be freely rotatable with the vertical center line 2c of the artificial upwelling generator A ″ as the rotation center.

FIG. 16: is a whole block diagram of the artificial power updraft generator B provided with the hydroelectric floating body which concerns on the 4th Embodiment of this invention, and this hydroelectric floating body. FIG. 17 is a plan view thereof.
In the first to third embodiments, the wave power generation device 70 is mounted on the floating power generation floating body 1 in that the first to third embodiments are largely different from the fourth embodiment. Therefore, the apparatus has a very complicated structure. However, since the wave power generator 70 is not provided in the fourth embodiment, the structure of the device is greatly simplified. For example, in the first to third embodiments, the converging levitation body 4 and the inclined plate floating body 10 are alternately connected, but in the fourth embodiment, the cylindrical divided floating body 75 is simply connected. It has become.

  Also in the ballast tank portion at the center of the apparatus, the first to third embodiments have a two-stage structure with the drainage 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 only one ballast tank. However, depending on the sea area such as the installation location, sea area, sea conditions, etc., it may be economical and the power generation cost may be lower if the wave power generation device 70 is not provided. For this reason, the descriptions other than those described with reference to FIG. 15 are almost the same as the descriptions according to the first to third embodiments, and the description thereof is omitted.

  FIG. 18 is an enlarged longitudinal sectional view of a deep water (bottom water) discharge portion of the artificial upwelling flow generator B in the fourth embodiment of FIG. The ballast tank BTa is a buoyancy chamber and has a structure that allows workers to enter and exit during maintenance. For this reason, there are also provided entrances and exits for workers, equipment entrances and exits, piping for air and ballast water, blowers, water, and drainage equipment. A discharge tank 76 is provided at the center of the upper portion of the ballast tank BTa. The discharge tank 76 includes a discharge tank bottom portion 76a, a discharge tank upper portion 76b, and a discharge tank conical portion 76c, and a water intake pump from a vertical intake pipe 7a. Deep water (bottom water) ST pumped up by 8a (described in FIG. 16) is discharged to the discharge tank bottom 76a through the nozzle 15c.

  The discharged deep layer water (bottom layer water) ST is discharged to the upper surface of the inclined surface of the ballast tank upper inclined wall BTb through the upper discharge tank 76b and the discharge duct 76d of the discharge tank 76.
