It is known that deep sea water rich in eutrophication is effective for aquaculture of fish and shellfishes. Therefore, when spraying deep sea water into the area around the floating fish reef, the deep sea water should be taken from a predetermined depth at a facility built near the coast, or a certain length of deep sea water should be taken from a workboat at sea. A possible method would be to transport the deep ocean water taken off by lowering the water pipe, and then discharge it to the floating reef.

However, these methods for deep sea water intake require the construction of a large-scale deep water intake facility, and a deep ocean water carrier is required between the area where the intake facility is installed and the area where the floating fish reef is installed. Therefore, there is a problem that a large cost is required. In addition, the method of transporting a large amount of deep sea water at a time by a deep sea water carrier and discharging it is not suitable for floating fish reefs that need to continuously spray deep sea water for a long time. There is also. The present invention provides a conventional floating fish reef with a pumping device that operates in accordance with the waves, and uses this pumping device to withdraw deep ocean water from a predetermined depth to solve the above problems. Is what you do.

FIG. 3 is a side sectional view of a floating reef according to a third embodiment. 1 to 4 indicate substantially the same members.

First, a first embodiment will be described with reference to FIG. The floating fish reef of this embodiment also has an annular (or angular) buoyant body 1 constituting the main part of the floating fish reef, and a mooring line 6 for mooring the buoyant body 1 to the sea floor and holding it at a fixed position.
And an eyepiece 5 for connecting a mooring line, and an inner cylinder 3 is mounted through the center of the buoyant body 1. The inner cylinder 3 is formed in a shape in which both upper and lower ends are opened, and a pumping mechanism is provided on the inner side in a state of being completely immersed in seawater. Reference numeral 4 denotes a plurality of support legs attached to the lower portion of the buoyant body 1 at appropriate intervals.
An eye plate 5 is attached to a horizontal rod 4a connecting the lower ends of the support legs 4.

The pumping mechanism comprises a piston pump 16 and a brake plate 15 attached to the lower end of a piston rod 16c of the piston pump 16. The piston pump 16 is fixed to the inner cylinder 3 via a support member 17. ing. The upper end of the inner cylinder 3 is set slightly lower than the upper end of the buoyant body 1.

An annular deep seawater temporary storage tank 2 which is surrounded by the upper inner surface of the buoyant body 1 and the upper outer surface of the inner cylinder 3 and whose top surface is opened and whose bottom plate 2a is formed lower than the sea surface 01 is formed. Formed in the buoyant body 1, the deep sea water discharge pipe 14 connects between the water discharge port 16 a of the piston pump 16 and the water storage tank 2.

Further, the water suction port 16b of the piston pump 16
The flexible hose 9 for deep sea water intake is connected through a deep sea water intake pipe 13. A valve is provided at each of the water outlet 16a and the water inlet 16b.

An eye plate 7 for connecting a water intake line is projected from the support leg 4, and a chain 8 for suspending a hose retaining metal fitting 10 is attached to the eye plate 7. Reference numeral 11 denotes a hose guideline, and reference numeral 12 denotes a hose connection hardware attached to the hose guideline 11 at a predetermined interval.

In the above configuration, when the buoyant body 1 moves up and down due to waves, the cylinder portion of the piston pump 16 fixed to the inner cylinder 3 moves up and down with the same cycle and the same amplitude as the buoyant body 1. The brake plate 15 disposed in the seawater inside the cylinder 3 cannot move up and down following the buoyant body 1 due to the resistance of the seawater, and the piston pump 16 operates by the phase difference and the amplitude difference. By such operation of the piston pump 16, the flexible hose 9 for deep ocean water and the deep ocean water intake pipe up to the water intake 16b of the piston pump 16.
The deep sea water that has been artificially rising through 13 is sucked up, and is passed through a deep sea water discharge pipe 14 to temporarily store deep sea water 2
Is discharged.

In the deep ocean water temporary storage tank 2, the deep ocean water discharged from the deep ocean water discharge pipe 14 by the operation of the piston pump 16 continues to be sequentially stored. The deep ocean water that has sufficiently touched the air and sunlight in the deep ocean water temporary storage tank 2 overflows from the upper end of the inner cylinder 3 and falls on the sea surface inside the inner cylinder 3, where the surface water Floats continuously mixed with natural water and spreads in the seawater around the reef.

The flexible hose 9 for deep sea water intake, which is connected to the deep sea water intake pipe 13 and hangs down to the deep sea water intake depth and is open at the lower end, has a vicinity of the sea surface due to the influence of the fluctuation of the buoyant body 1 and the tidal current. In order to ease the burden of these forces, the flexible hose 9 for deep sea water intake has sufficient slack and the eye plate 7 for connecting the intake line A hanging chain 8 of a hose retaining metal piece 10 with little expansion is attached, and a flexible hose 9 is fixed to the hose retaining metal piece 10 attached to the chain 8, so that the force of the flexible hose can be reduced. ing. Further, under the chain 8 for suspending the hardware 10 for retaining the hose, a hose guideline 11 is hung down to the water depth, and the flexible hose 9 for taking in deep sea water is removed at necessary intervals at predetermined intervals. The hose guide hardware 11 is connected to the hose guide hardware 11 by a hose connection hardware 12 so that the force of the hose can be reduced.

As described above, since the tension acting on the flexible hose can be suppressed by using the hose retaining hardware 10 and the hose guideline 11, water can be taken from a large depth by using a large number of flexible hoses having a simple structure and material. Can be made possible.

In the first embodiment, the shape of the deep ocean water temporary storage tank 2 and the deep ocean water pumping mechanism are as follows.
The size, mounting location, and mounting method are not limited to the above examples, and it goes without saying that the size and shape of the floating reef, the amount of deep sea water intake, and the like can be arbitrarily changed.

Next, a second embodiment will be described with reference to FIG. In the second embodiment, the inner cylinder 3 is attached to the top of the inner cylinder 3 which is attached through the center of the buoyant body 1.
In order to make the inside of the inner space airtight, an inner cylinder blocking plate 19 is attached, and an inner cylinder space 21 which is an airtight section is formed inside the inner cylinder 3 with the floating reef floating on the sea. . Then, the sea surface inside the inner cylinder space 21 is maintained at a water level at which the head pressure and the air pressure of the inner cylinder space 21 are equal, and in this state the inner cylinder space 21 becomes an airtight section, in which a pumping mechanism is provided. It is provided to protect from the impact of waves and the adhesion of marine products.

In the above-described configuration, when the buoyant body 1 moves up and down due to waves, the inner cylinder 3 moves as the buoyant body 1 changes in draft.
Since the water pressure at the lower end of the inner cylinder 3 changes, the air pressure in the inner cylinder cavity 21 fluctuates through a change in the sea level in the inner cylinder 3, and is transmitted to the belofram 18 as a telescopic operation accompanying the change in the external pressure, and is connected to the belofram 18. The piston movement of the piston pump 16 is induced, thereby sucking up the deep sea water artificially upwelling through the deep sea water intake flexible hose 9 and the deep sea water intake pipe 13 to the water intake 16b of the piston pump 16. Then, the water is discharged into the deep sea water temporary storage tank 2 via the deep sea water discharge pipe 14.

A temporary deep-sea water tank 2 which is surrounded by an upper inner surface of the buoyant body 1 and an upper outer surface of the inner cylinder 3 and has an open top surface and a bottom plate 2a at a position lower than the sea surface is provided with: By operating the piston pump 16, the deep sea water discharged from the deep sea water discharge pipe 14 is sequentially stored, and in this deep sea water storage tank, the deep sea water sufficiently exposed to the air and sunlight is converted into a buoyant body. Overflowing from the deep sea water discharge pipe 20 provided through 1 and falling on the sea surface around the floating reef, where it naturally mixes with the surface water and continuously diffuses into the seawater around the floating reef become.

Also in the second embodiment, the shape, material, internal volume, expansion / contraction stroke,
The inner diameter and the spring constant are not limited to the examples, and can be arbitrarily selected according to the size and shape of the floating fish reef, the amount of deep sea water intake, and the like.

Further, a third embodiment will be described with reference to FIG. In the third embodiment, the skirt 24 is provided so as to surround the inside of the plurality of support legs 4 provided below the buoyant body 1, and the marine vessel surrounded by the bottom of the buoyant body 1 and the skirt 24. A deep water mixing section 27 is formed.

A deep ocean water intake basin 26 is provided near the upper part of the deep ocean water mixing section 27, and a plurality of deep ocean water branch pipes 25 are provided on the inclined outer surface of the bottom plate 1 a of the buoyant body 1 from around the basin 26. A deep sea water spouting gutter 23 is attached to the discharge port at the upper end of the deep sea water intake branch pipe 25 so as to be inclined upward along the radial direction.

A check valve 22 is provided at each of the discharge ports of the plurality of deep sea water intake branch pipes 25, and the deep sea water intake branch pipe 25 is provided with a check valve 22.
The deep sea water that has been artificially springing up to the discharge port at the upper end of the water is operated by the check valve 22 with the fluctuation of the draft caused by the buoyant body 1 swaying up, down, left and right due to the waves,
The water is continuously discharged into the deep sea water spout 23 and is discharged to the deep sea water mixing section 27 via the deep sea water spout 23.

Also in the third embodiment, the combination and shape of the deep sea water intake basin 26, the deep sea water intake branch pipe 25, the deep sea water sprinkler gutter 23, and the check valve 22 are limited to the examples. Needless to say, it can be arbitrarily changed according to the size and shape of the floating fish reef, the amount of deep sea water intake, and the like.

[0031]

As described above, according to the floating reef of the present invention, the following effects can be obtained. (1) Deep seawater can be continuously taken and sprinkled for each floating fish reef unit, and the seawater around the floating fish reef can be fertilized to contribute to the breeding of seafood. (2) A water tank was installed in a part of the buoyant body of the floating fish reef, and a flexible hose was connected to the lower part of the water tank, so that the deep water could be transported continuously from other deep water intake facilities without lifting the supply. It can be self-sufficient, and equipment costs, transportation costs, and human burden can be significantly reduced. (3) The pumping mechanism incorporated in the floating fish reef operates following the waves, but the entire pumping mechanism is protected by the inner cylinder of the floating body of the floating fish reef and then completely submerged in the sea, or it has an airtight structure. With the configuration in which the equipment is installed in an empty space, it is possible to avoid receiving the shock of the wave directly, and the pumping mechanism can be operated without directly floating the shock of the wave and using natural energy. (4) A large amount of flexible hoses are used to draw deep sea water from a floating reef to a specified deep sea water intake depth using a large number of flexible hoses. In order to mitigate the effects of elongation and deterioration, the hose guide line should be connected with the necessary slack in the hose, and the excess force borne by the hose should be deposited in the hose guide line and drooped. A simple and inexpensive floating reef using a hose can be obtained.
