Description

[Detailed Description of the Invention] Currently, the amount of precipitation on each land on the earth is determined by the topography of each land and the climate zone to which the land belongs, so there are some areas on earth that lack water, while others have an excess of water. There is also. However, in areas with water shortages, there is a KU limit for water usage in flat areas due to rainfall and rivers, and in areas with poor conditions, even if the land is adjacent to the sea and has sufficient sunlight and temperature, there is a shortage of fresh water. There are many places in the world that lack sufficient vegetation and become deserts or semi-deserts, creating climates that are difficult for humans to use or settle in.

Therefore, if a large amount of fresh water were stably supplied throughout the year to such poor environmental areas, various industries such as agriculture would flourish, people would settle in, and villages and towns would develop.
The utilization of unused land from the perspective of limited land use on the earth and the development of industry brought about by this will eventually encourage an increase in social employment, and land that has been wasted until now will be wasted. Let's promote the happiness of humankind by leading to the effective use of solar energy.

For this reason, it is best to first send fresh water to areas with water shortages from areas with water surplus, etc. In particular, a percentage of the fresh water that is thrown into the sea at the mouths of large rivers should be transferred to areas with underwater water pipes or dedicated water carriers. It is thought that transportation to desert areas is fully possible. However, on the receiving side of freshwater, large-scale freshwater storage facilities are required to ensure a stable supply and stable continuous use of large amounts of water, but establishing an artificial reservoir on land requires large-scale civil engineering work. In short, not only is it difficult to compensate for the price of the water that could be used, but the creation of vast reservoirs on land also results in the loss of flat land in favorable conditions that can be conveniently used by humans.

Furthermore, if a reservoir is simply created by excavating land and creating a depression, even if it is made with a clay layer at the bottom, there will be considerable loss due to percolation underground, so it cannot be overlooked. In addition, an effective method has been developed recently to prevent water leakage by laying plastic film on the bottom of the pond, but it is much less desirable to construct a large-scale reservoir on land that can cover a vast area on a national scale. It is difficult to say that it can be implemented anywhere unless the conditions are met, and even when actual construction is carried out on land, it is not possible to sufficiently measure the depth of the reservoir or for economic reasons.

Currently, the most common artificial lake built in the building is the dam type water storage system, in which river water is dammed up by a dam, and it is one of the largest artificial lakes. As mentioned earlier, there are not many suitable locations on earth for dam construction due to the topography and environment of the land and hinterland, and at the same time, the absolute prerequisite for the construction of these dams is that the location has a river with sufficient flow. is necessary. However, the land that is currently left unused on earth as desert, etc. is largely due to the fact that these conditions have not been met until now, and as mentioned earlier, there are coastal areas. Despite this, many areas of land have become barren deserts due to lack of water.

The present invention utilizes the vast space of the sea on land in a location like Jin, and creates a thin plastic film on seawater and freshwater, which have the same physical properties but differ in the amount of ingredients contained. With the simple structure of storing a large amount of freshwater by simply separating it from the water and suspending it on seawater, it is possible to create an almost infinite number of huge artificial freshwater lakes at an extremely low cost. If freshwater could be supplied to this artificial offshore lake by some means, it would be possible to stably supply a large amount of freshwater to the terrestrial coastal zone near where the lake is located year round. It is a base that can be used.

As a result, dry land becomes more green and humid, and the harsh and poor environment of the past becomes suitable for the survival of living things including humans, and desert-like conditions are created on a global scale. It is something that can improve the land.

Hereinafter, embodiments of the floating artificial freshwater lake according to the present invention will be described in detail.

FIG. 1 is a detailed sectional view showing a part of the structure of the present invention, FIG. 8 is a sectional view that clearly shows the overall structure, and similarly, FIG. 11 is a plan view showing the outline. be. In other words, as a general outline, fresh water (2), which has a lower specific gravity than seawater (1), is placed in the ocean at an appropriate depth where the seabed (3) is not too shallow and is deep enough for the construction of the present invention.・A huge container made of plastic film that is strong and has a certain degree of flexibility like film, etc., and that is easy to adhere when working. An artificial lake was created and floated on the sea, and the plastic film lubrication (4) was filled with fresh water (2 liters) brought from elsewhere, and then seawater (1 liter) was poured into it.
) and freshwater (2J K I-1) Although there is a difference in specific gravity, a huge floating freshwater artificial lake is created on the sea so that the free water surface (1) (gin) of both is almost the same at all times.

However, seawater is constantly in motion, generating slow ocean currents due to the effects of the Earth's rotational force and wind power, and in areas such as inlets and bays, tidal phenomena are noticeable due to the gravitational pull of the moon and the sun. Therefore, if freshwater (2) is simply trapped and suspended on seawater (1), the freshwater lake will move and be washed away. So this Junsei (4)
Supports (5) are erected at appropriate intervals on the outside 1i5 so as to surround it, and the lower ends of the supports (5) are fixed to the seabed (3) using concrete foundations (6). Also, the water floating on the sea (4) 1-1, the fresh water filled in it (2)
) Depending on the amount of water, it will be flat or heavy, but the upper edge of Junsai (4) should always be above the sea and maintain a constant height so that it can fully fulfill its role as a bulkhead. Therefore, the bottom (4) of Junsei (4) will move up and down to correspond to the fresh water t.Therefore, by absorbing the vertical movement of the bottom (A), Junsei (4)
In order to prevent the film constituting the film from being damaged by excessive force being applied locally, the entire side wall (4I) of the film (4) has a bellows-like foldable structure.

In addition, the connection between the four walls (4) and the pillar (5) is made by the following method.In other words, the cross section of the pillar (5) is cross-shaped as shown in the figure, and has a cross hole (9) in it. A large number of support plates (7) are inserted into the cross-shaped holes (9) with the pillars (5) passing through them as shown in the figure, but the support plates (7) are rotated horizontally by the cross-section pillars (5). Although it is not possible, there is a gap between the cross hole (9) and the support post (5) so that it can slide up and down, and while maintaining the gap at equal intervals front, back, left and right, the support plate (7) is attached to the support post (5). The support plate (7) has a cross hole (
9) Sliding wheels with extra edges ←The sides of the column are pressed from all directions by Q.

This support plate (7) has two pillars (5) between the top and bottom of each.
Bellows (8) are installed on both sides of the upper and lower support plates (
7) Connect (7)...... and attach the top support plate (
7) It is longer and stronger than the others, and the water surface (1')
(1') Each bellows (8) (8) floating above and connected to this and each support plate (7) (7)
......is supported in a suspended state.

The end of each supporting plate (7) configured in this way on the Junsei (4) side is attached to the bellows-shaped side wall of Junsai (4) (four of which are bent so as to protrude toward the seawater (1) side). Plasti 1. A crease bar (6) made of cylindrical metal or hard plastic is placed inside the entire folded part of the plastic film.
Insert it so that it is wrapped in the plastic film that makes up the Junsei (4), and the outside of it is made of semi-hard and elastic plastic with a C-shaped cross section. C), and then temporarily fix the above-mentioned support plates (7) to plier-shaped grips that can be fixed with bold nuts etc. on the support plate (7) side at the positions where each of the above-mentioned support plates (7) are located. Securely secure the Junsei film (4) by placing it on top of the cover tube (6). In this case, the outer surface of the folding film (6) and the inner surface of the cover tube (to) should be smooth to prevent the film (4) from being damaged.
If it is made of metal, perform defensive treatment.

Also, fold the film of the side bag (4) inward and use fresh water (2).
) The folded part protruding to the side is similar to the folded monthly salary (12'
), wrap the top with a side bag (4 inch plastic film), then fit and cover the cover rod (13') on top of it, and then insert a large 0υ clothespin-shaped spring on top of it. Clips Qd and K are used to separate them at appropriate intervals, but
Since the other end of the clip 0Q is not fixed anywhere, the bent portion of the film on the freshwater (2) side can freely float in the freshwater. However, in order to prevent this part from bending and protruding toward the seawater (1) due to the water pressure inside and outside the side bag (4), the shape of the bellows would be deformed into an incorrect shape.
On the seawater (1) side, one end of the tension arm 0 is attached to both ends of the covering tube 0 so that it can rotate freely, and η is attached to this arm.
The other end is the protrusion 0 of the folded monthly salary (1z) with the protrusion mentioned above.
Attach it so that it can rotate freely as well.

In addition, the inner space is connected to allow water to flow upward and downward through the water passage hole α between the bellows (S) and the support plate (7) K between each of the support plates (7), and the bellows (S) at the lowest end ( 8
) is directly below the support plate (7) on the lower side. They are connected so that water can flow through each other, and the water supply pipe for bellows (1)
As shown in Fig. 12 and Fig. 13, the control system (21') in the control shed (to) on the land to the left of the control system Qυ (as shown in the continuous line in both figures) K is guided. In addition, the upper end of the bellows (8) has an adjustment exhaust hole (c) above it through the ventilation hole θ of the upper support plate (7) located above the bellows (8), so that the bellows (8) 8) Prepare for when pressure adjustment is required.

During normal use, the bellows (8) (8) attached to both ends of the upper support plate (7) are inflated by pressurizing air into the water bladder (α1)tc, and slide up and down along the column due to its buoyancy. ...and a side bag with bellows-like folds that can freely expand and contract up and down through these (4)
The side wall (4I) and bottom (4') of the water tank are suspended and serve to support the water surface (wa).
) is supplied from the freshwater supply pipe (c) and the amount of water stored increases, or the amount of freshwater (2) used on land increases and the
A large amount of water (2) is sucked out by the water pump (a) through the freshwater suction pipe having a valve (28'), and the amount of fresh water in the isolateral bag (4) decreases, causing a change in the amount of fresh water in the isolateral bag (4). When
Accordingly, the bottom (4') of the side bag (4) floating on the sea moves up and down, and if the water pressure inside the bellows (8) is left free without regulating it, water will accumulate. The water pressure inside and outside the trap is always close to zero, and the water pressure inside and outside the trap is always close to zero.
8) Of course, there is no fear that the film constituting the huge side bag (4) will be damaged by water pressure. In particular, water goes in and out of each bellows (8) (8)... from the control system line Q
Since water is supplied at a free water level through the bellows water supply and drainage pipe (1) included in At the same time, the entire bellows (8) (8)... also expands and responds by absorption, and conversely, when the amount of stored water decreases, it is pushed up by the pressure of the seawater (1), forming a bellows shape. side wall (4 folded, full bellows (8)
(8)......contracts, so the bellows (8)
The water inside should be returned to the control freshwater pond on land.

In this way, in the floating artificial freshwater lake of the present invention, the free water surface inside and outside is always close to zero, although there is a slight difference due to specific gravity. A side bag (4) is made of film to block the inside and outside, and in normal weather, small and medium-sized waves can cause splashing, and a simple wave shield that is not very high can be used as a barrier (7).
) can achieve the purpose of avoiding the contamination of seawater (1). This makes it possible to create a gigantic artificial freshwater lake in the vast, almost limitless space of the ocean, which can serve as a stable water supply source for coastal areas on land throughout the year.

However, nature is not always peaceful. Especially when building such a huge artificial facility on top of a fluid called the ocean, it must be able to cope with storms that attack irregularly. In other words, if a facility constructed of a thin film like the one of the present invention is directly hit by a large wave containing strong energy from a storm, all of the facilities will be damaged. However, in the ocean, even if a storm generates large waves on the sea surface, as the depth increases, the movement of the seawater (1) gradually decreases, and the effect becomes less of a problem at slightly deeper depths.

Therefore, in the present invention, all of the fresh water (2) stored in Kl-j during a storm is dumped into the sea, and the entire device is allowed to sink near the ocean floor (3), thereby allowing evacuation. That is, Figures 8, 9, and 10 show an overview of the process.When a storm approaches, which can be predicted by the weather forecast, the first thing to do is to carry out hydration by command from the control shed (A). (4) Open all the electromagnetic valves 0◇ attached to the top of the water surface air bladder a floating all around it, and force suction and exhaust through the air pipe 6, which is included in the control system line Qυ. and removes the buoyancy of the water surface air bladder (1),
At the same time, the fresh water in all the articulated bellows (8) (8)... is also sucked and drained by the bellows water supply and drainage pipe (A), causing all the bellows (8) (8)... to contract. . At that time, the adjustment exhaust hole (c) at the top of the bellows (8)
Close the solenoid valve (31') for bellows ventilation attached to it, and the inside of Teherose (8) becomes negative pressure! 7. Helps shrink and prevents seawater (1) from entering. Then, the weight of the support plate (7), bellows (8), etc. will cause the column (5) to
), the entire circumference of Junsei (4) sinks into the sea,
Seawater enters into the Junsei (4) and mixes with freshwater.
2) Ha was abandoned in the ocean and became one with the seawater (1), but the entire main equipment related to Junsei (4) was evacuated near the seabed (3) where there is almost no movement of water, and the main equipment was evacuated to the sea surface. Only the top of the pillar (5) with low wind resistance and the wire rope (9) for support and fixation are left on top, waiting for the storm to pass.

When the storm passes and it becomes calm, the aforementioned water surface air bladder α1)
Compressed air is sent through the two air pipes to inflate it and give it buoyancy, and the entire Junsei (4) is slowly floated close to the sea surface (1). In that case, keep the inside of each bellows (8) depressurized so that it does not swell, and when the entire bellows (8) rises to the sea surface as much as possible (nearly one bellows), the bellows (8) is attached to the underside of the lowest support plate (7). Compressed air is sent into the sea air bladder (to) through air pipe 0 to inflate it and float the area around Junsei (4) even further above the sea surface. Seawater (1) remains inside the Kakjunsei (4), so
As the seawater (1) is pumped out using a separately installed drainage pump (c) with a float, the center of the bottom (4') of the Junsei (4) swells up as shown in Figure 9. It becomes equal to the free sea level (1).In other words, there is no seawater in the center, and only a ring-shaped seawater (1) remains in the peripheral area.So, this time, the seawater (1) remaining in Junsai (4)
) A simple weir partition is installed in a ring-shaped part of the weir to prevent water from mixing on both sides of the weir. While pumping out seawater (1), the same amount of fresh water (2) is injected into the other side of the weir. Then, while maintaining this water surface (1')<no, the seawater (1) remaining in the ring of water (4) will be replaced by fresh water (2), and eventually it will all be desalinated and discarded. .

After that, the pumping operation is stopped, and only fresh water (2) is continued to be injected, causing the bottom of the water tank (A) to settle down, and when no undue force is applied to any part of the water tank (4), the amount of water increase increases. The bellows (
8) Slowly send water through the bellows water supply and drainage pipes (A) to inflate each bellows (8) to the required extent, and then leave the interior of the bellows (8) to the free rise and fall of the hydrating bottom (4). Return to the free water surface state so that you can follow the 8th
Return to the normal usage state shown in the figure.

In this case, in order to create a ring-shaped water surface inside the water tank (4), it is necessary to provide some space in the film of the water tank bottom (4') in advance, and to take steps such as settling, flotation, and drainage of the water tank (4) as a whole. ,
The work is promoted and monitored using a computer equipped with a detector, a television, etc., using the control system (2P) in the control shed.
Of course, it can be remotely controlled by K.

The Junsei (4) that has been described so far is a standard independent floating type surrounded by seawater (1) on its entire circumference as shown in Figure 12. In order to reduce the problem, it is also possible to use a floating type as shown in Figure 13, in which the - side of Junsei (4) is replaced with a continuous line (A).

This berthing type has traps on both sides of the lake (walls 11 and 11 (4
One end of the foundation (b) is fixed, and at the same time the connecting wire (two
) A film fixing line (27') is installed on land to stop the wet end, but in both cases, the necessary water is connected to the land from the artificial lake via the fresh water suction pipe (c) and the water suction pump (25'). It absorbs water and sends it to the place.

% to freshwater (2) seawater (1) to protect the invention in an emergency.
) Abandoning water into the water is the same as river runoff, and does not pollute the natural world. However, even if the purpose is to avoid disasters, it is necessary to abandon a large amount of stored fresh water (2), which is planned for use, because the amount of water required on land cannot be met immediately by supplying water from elsewhere via underwater water pipes.

In such a case, the present invention has a configuration in which a large number of floating artificial freshwater lakes created by the above-mentioned water traps (4) are connected using underwater water pipes (c) as shown in Fig. 14. , the local freshwater (1) shortage can be compensated to a considerable extent. In other words, normal storms are caused by atmospheric vortices called typhoons or hurricanes. The strong air currents brought about by the extremely low pressure trap near the center cause large waves in the seawater, exerting terrifying destructive power, but fortunately, the strong wind area is usually relatively narrow and limited. It is something that passes within a range. Therefore, in the case of a large landmass, the artificial lakes of the present invention can be set up in a chain along the sea area on the same side, and if each artificial freshwater lake is connected with an underwater water pipe (b), the center of the typhoon will pass through. Because of that, fresh water (2)
Even if there are one or two artificial lakes that have been abandoned, they can immediately receive fresh water from other artificial freshwater lakes via the underwater water pipe 04 after the typhoon has passed, so the artificial lakes normally receive fresh water. Water shortages can be kept to a minimum on land in the areas where they were owned. What I would like to add here is that during calm times, when water is supplied via underwater water pipes (b), the water is normally increased near the mouth of the river.
Because the water is sent slowly at low water pressure through thin, large-diameter pipes, a huge water storage lake like the one in the present invention is required on the water receiving side. Therefore, even if a large amount of stored water is lost due to storm avoidance, it will take a significant amount of time to restore the water volume with the normal water supply capacity of underwater water pipes (b) from rivers, so in an emergency, a chain trap will be connected. These artificial lakes must help each other to supplement fresh water (2). Furthermore, regarding supplementation, it is only in the event of a disaster that even when the amount of water used in an artificial lake increases by a large percentage, it is natural that there will be more water available than other artificial lakes.

Figure 14 shows how water is supplied to the sea along the coast (4)
This figure shows the state of a part of an artificial freshwater lake that is connected in a chain by underwater water pipes (b) and siphons (g).The management of the entire system that connects these artificial freshwater lakes is Control line connecting control shed CZ [...
21') via a central control room (23'). In other words, the underwater water pipe (b) is a mooring rope (b)
The trap is placed at key points on the seabed (3) using a concrete foundation (6") for anchoring, and reinforced concrete spiral piles (not shown) to connect the buoyancy of the floating tube (g) and the buoyancy of the tube (b) itself. The lobe (c) is fixed in the sea at a certain depth by tensioning the lobe (c) in a buoyant state while cooperating with the underwater pipe (b), and one end of the underwater water pipe (b) is used to draw water from near the mouth of a river belonging to another land. , similar to the flow of a river, a constant amount of water always reaches the sea level (
The water is continuously and slowly delivered by the slight water pressure resulting only from the water level at the water intake which is slightly above zero. The other end of this underwater water pipe (b) is equipped with a water discharge valve as a safety device that can be opened and closed by remote control to dump excess water into the sea. Undersea water pipes like this (b)
An Ir1T type branch pipe is attached to a position corresponding to each freshwater lake, and a freshwater supply pipe (c) is connected to this to send water to the artificial freshwater lake. However, the side walls of artificial freshwater lakes (four of them have a bellows-like structure, so there are no pipes attached to these parts underwater).
Since it is not possible to connect directly to the water, the wave shield added to the entire circumference of the upper edge of Junsei (4) allows the siphon (to) that goes over the barrier (g) to drain the fresh water in the freshwater lake (2). The fresh water (2) in the underwater water pipe (b) is continuously discharged airlessly, and the fresh water (2) is continuously supplied by the slight water pressure generated by the small water level difference. However, the underwater water pipe (b) is thin but has an extremely large diameter, so although the flow rate is not fast, it has a large amount of water, so even if it is a huge artificial freshwater lake, the amount of water supplied is sufficient to match the size of the lake. Therefore, the freshwater supply pipe and siphon pipe (2) connected to this pipe (b) and the siphon pipe (2) are also quite large diameter pipes, and the siphon (2) extends into the air.
When filled with water, it becomes quite heavy. Therefore, in order to support the weight of this siphon (2) and withstand wind and waves, suspension supports (g) were erected on the concrete foundations (6) installed on the seabed (3) and wire ropes (9) were used. and suspend the siphon part.

However, when new underwater water pipe 04 was installed, a siphon (
Connect the freshwater supply pipe (c) including the subsea water pipe (
Even if you try to pump water only by the water level difference between the inside of b) and the sea level (f) or the freshwater surface (force), the siphon effect will not work because air is in the siphon (to) and the water is not continuous. Therefore, a siphon exhaust hole (6) with a siphon exhaust pump (31) and an air backflow prevention ball valve 01 is installed at the top of the siphon. , this pump (31) is also electrically connected to an air sensor (6) that detects when the water level near the top of the siphon (b) falls and the top fills with air and issues an electrical signal. The siphon (a) is automatically operated only while air remains inside the siphon (b), and the siphon (b) is automatically controlled so that the upper part of the siphon (b) is always completely filled with water and the siphon effect is fully exerted. Air in the upper part of the siphon (A) is caused by air bubbles contained in the flowing water or gas dissolved in the water being vaporized during construction or during operation; The water level can be read from the outside by means of a transparent glass tube installed in the water level.

In the case of normal water supply, open the disc angle conversion type water stop valve installed at the boundary between the water supply pipe and the fresh water supply pipe, and as mentioned above, water is supplied by natural flow due to the water level difference. . In that case, a suction/discharge type axial flow port having a propeller 0 at the fresh water outlet (g).

Since the pump θ'I)Vi is stopped, the flowing water passes between the blades of the stopped propeller and is continuously supplied into the side bag (4) of the artificial freshwater lake. However, if the inside of the side bag (4) is filled with fresh water (2) to its maximum capacity and there is a risk of damage to the side bag (4) due to the need to receive more water, close the water shutoff valve ■ and fill the fresh water with water. Stop the influx.

In addition, as mentioned earlier, in order to compensate for water shortages in other artificial freshwater lakes, if water is not allowed to flow backwards from the artificial freshwater lake to the underwater water pipe (b) via the siphon) and the freshwater supply pipe (7), the freshwater The suction/drainage axial flow pump @no located at the discharge port is rotated in the water suction direction to pump water. At the same time, the suction and discharge type axial flow pump θf)ld of the artificial freshwater lake receiving water supply is rotated in the discharge direction,
Water can be rapidly transferred from other artificial freshwater lakes to the required artificial freshwater lakes with high efficiency. In that case, underwater water pipes (b) will be installed from other land rivers, etc. as the water source of the artificial lake.
Since the gradual water supply continues as it is, the flow velocity increases in some parts of the underwater water pipe (b). In addition, when the siphon is full of water, the weight of the water on the downstream side and the rising side cancel each other out, so the burden on the suction/discharge type axial flow pump is simply the sea level. (Since the effect is only due to the difference in the water level between the water supply pipe (1) and the underwater water supply pipe (b), a multi-stage propeller is recommended for power-driven water supply in the freshwater supply pipe (c), which has a fairly large diameter. A low-speed rotating axial flow pump θ using (g) or a vertical type pump having a spiral propeller may be used.

In this way, artificial freshwater lakes are constructed based on the structure of thin membrane-like side bags (4) installed on the sea, either singly or in a chain, but these side bags (4) are not carefully maintained. Otherwise, it will break and seawater will get mixed in, rendering it useless as fresh water. In particular, the Junsei bottom is suitable for the capacity of the side bag (4).
If the depth of 4') is not monitored and understood at all times, unexpected accidents may occur. Therefore, depending on the size of the lake bag (4), such as the center, the center, and the four corners of the water tank (4), the depth of the water tank (4) must be constantly monitored at one or more locations.

In order to prevent the water surface Kfl above the side bag (4) from moving, tilting, or falling down, there are two anchors installed on the seabed (3) outside from the top of the support (5). Basics (
6″′) fixed with two-wire rope (9), and for the other direction, the opposing support (5) on the other side beyond the side bag (4)
A wire rope (9) is stretched between each of the wire ropes (9) to create tension. In order to prevent the wire rope (9) from sagging on the side bag (4), the small floats θ0 are placed at an appropriate interval [i It is attached and floating on the water surface (2). Next, fit a donut-shaped float ring over this small float at an appropriate position on the wound, as if straddling the wire rope (B), and float it on the freshwater surface <'ttVc, from the bottom of this float (A). An ultrasonic generator (
52) The ultrasonic waves are emitted toward the seabed, and the reflected waves are received via a cup-shaped sound collector (58) attached to another bottom surface of the same donut-shaped float. Depth gauges are placed at key locations to confirm the depth of reflection by reading the delay of echo waves using an ultrasonic receiver (54) mounted on the float.

However, plastic, glue, and film placed in water have poor ultrasonic reflection efficiency and tend to have inaccurate sensitivity. Reflective iron plate (5
5), and place a plastic holding plate (55) from the bottom surface of the iron plate (55) to prevent it from moving.
6) A permanent magnet (57) coated with VC is attracted and fixed through the film of the wet bottom (4') to ensure reflection of ultrasonic waves. The holding plate hole (58) is for the diver to conveniently insert a handle when attaching and detaching the magnet (57).

If the present invention is installed in the sea, large aquatic animals such as dolphins, whales, sharks, and marlin may approach from the open ocean and cause damage (4). In order to eliminate the chance of contact with the bag (4) Vl, a net foundation is installed around the artificial lake. A relatively strong and easily visible pest control net (7) attached to the net (60) Ic is constructed to prevent approach and intrusion.

Furthermore, in order to prevent ships from colliding with and damaging these facilities at night, each support (5) (5)...
An indicator light (61) is attached to the top of the... and lights up to serve as a warning.

In the improved invention, the support plate (7), the folding rod (b), the cover tube (2), the grip α◆, the clip α→, the tension arm αη, the permanent magnet holding plate (56), etc. , all materials used underwater contain closed-cell foam (62).
It is necessary to provide appropriate buoyancy so that the specific gravity is almost equal to that of water, and to make the construction work easier by preventing these equipment and materials from becoming swamped in water, as well as reducing the weight of the materials attached. Be careful not to damage the moistened side walls (4, etc.).

As described above, the present invention is to transport fresh water from rivers, etc. on other land where there is abundant water to a coastal area where there is little natural fresh water on land, and to store and use it. By greening areas that have been considered barren for some reason, we can encourage various industries, including agriculture, and contribute to the healthy development of towns and cities.

In addition, the present invention not only creates an artificial freshwater lake inside a salt lake on land to help improve the irrigation of nearby arid areas, but also creates a purified water lake inside a natural freshwater lake to serve as a water source for water supply. can. Furthermore, if this device is developed, it will be possible to introduce clean seawater from the open sea into the inland sea, which has a highly polluted coastal industrial area, and conduct aquaculture. It will also be useful for storing water on remote islands in the ocean and in areas where rainfall is uneven depending on the season.

Claims (3)

[Claims] (1) A large number of pillars are arranged on the seabed in a rectangular or circular shape, and each of these pillars is fitted with a support plate that has a hole that allows it to slide up and down, and the pillars are passed through these holes. With the support plate in place, they are rubbed in multiple layers facing the same direction on the support plate, and a water surface air bladder is attached to the top support plate to give it buoyancy and to allow water to be sucked in and discharged between each support plate. A strong film wall that can be folded into a bellows shape is attached to one end of each layer of these support plates, which is surrounded by a row of columns and becomes the inner side, and the entire inner side is surrounded by a strong film wall. This artificial freshwater lake floating on the sea is characterized in that a single film bottom is placed on the lowermost metal edge of the peripheral film wall, and the entire film is used as a bag-shaped container filled with fresh water. (2) A number of pillars are erected on the seabed in a rectangular or circular shape, and a support plate that can slide up and down is attached to each of these wooden pillars, and the pillars are passed through the holes. Attach many of them one on top of the other, with the top support plate 1
In addition to installing a water surface air buoyancy bladder that can be press-fitted with CFL air and inflated to give buoyancy or suck out air to take away buoyancy, water can be sucked in or pressed in between each support plate, and water can be discharged or sucked out. A bellows was added to allow the support plate to slide, and a sea air bladder was installed on the underside of the bottom support plate to allow air to be pumped in and out. Add a strong film wall that can be folded like a bellows to one end of the inside, and surround the entire inside. The artificial freshwater lake is made up of a floating container filled with fresh water in the form of a film bag. Air is taken in and out of the water surface air bladder attached to the top support plate and the sea air bladder attached to the bottom of the bottom support plate. By coordinating various operations such as putting in and taking out water in the bellows between each support plate, during a storm, the water stored inside is dumped into the sea and evacuated to near the seabed, and after the storm has passed, it is floated sufficiently above the sea surface. This is an artificial freshwater lake that floats on the sea and is a type of sedimentation evacuation type during storms, which is characterized by the ability to freely sink and float so that the remaining seawater inside the lake can be replaced and removed with fresh water. (3) A large number of artificial freshwater lakes, which are constructed as bag-like containers made of film and are filled with fresh water to store them, are constructed in a row on the sea along the coast, and these rows of freshwater lakes are connected to freshwater by pipes that supply fresh water via siphons. A chain characterized by being connected to an underwater water supply pipe for transportation to receive water from a freshwater supply area, and by freely communicating freshwater in multiple artificial freshwater lakes so that freshwater can be exchanged between them.
