DETAILED DESCRIPTION OF THE INVENTION

[0001]

This invention resides in the deep sea
The present invention relates to a method and an apparatus for raising the water of a vegetative layer on the seabed to a shallow sea area for the purpose of raising the water of the vegetative layer to a shallow sea area.

[0002]

2. Description of the Related Art Conventionally, there has been proposed a technique of installing a concrete cylinder on the seabed in order to raise nutrients in the deep sea to a shallow sea.

[0003]

According to the conventional apparatus, a base end of a hose is connected to a lower end of a pumping cylinder of an intermittent air pumping apparatus.
Since the tip of the hose faces the nutrient layer in the deep sea, there is a problem that the amount of ascending nutrient is small.

[0004]

According to the above prior art,
There are upflow relatively few problems for the vast deep sea nutrients by the upward flow is the way to obtain the entrained water is succeeded in obtaining a large amount of upward flow.

That is, according to the present invention, the lower end of a connecting pipe for pumping is inserted into the upper part of the inside of a large cylinder whose lower part is inserted into a deep-sea nutrient layer, and an upflow generating means is connected to the upper end of the connecting pipe. This method raises the water of the deep sea vegetation layer to the shallow sea area, and raises the water of the deep sea vegetation layer to the shallow sea area, while raising the water of the deep sea vegetation layer to the shallow sea side by the upflow generated by the The generation means is an intermittent air pumping method, in which pressurized air is sent into a pumping cylinder and intermittently discharges air bullets to raise water. is there. In addition, an inlet is formed in the lower side wall of the reinforced concrete cylinder whose lower part is installed in the deep sea nutrient layer, and the upper part of the reinforced concrete cylinder is opened and pressurized air installed in the shallow sea area is pumped inside the pumping cylinder. To
It is a device for raising the water of the deep sea vegetation layer to shallow water, characterized by facing the lower end of the pumping cylinder of an intermittent air pumping device that intermittently discharges air bullets and pumps water. An auxiliary cylinder is connected to the upper part, and pressurized air is fed into the pumping cylinder inside the upper part of the auxiliary cylinder, and the lower end of the pumping cylinder of the intermittent air pumping device that intermittently discharges air bullets and pumps water is seen. It is a device that raises the water of the deep sea vegetation layer to shallow water, which is characterized by a lack of water. Next, an inflow port is formed in the lower side wall of the reinforced concrete cylinder whose lower part is installed in the deep sea nutrient layer, and the upper part of the reinforced concrete cylinder is opened, and the lower end of the connecting pipe is inserted and opened therein, and the connecting pipe is opened. The upper end of the hose is connected to the distribution box, one end of a plurality of hoses is connected to the distribution box, and pressurized air installed in a predetermined shallow sea area is fed into the pumping cylinder at the other end of the plurality of hoses. An apparatus for raising water in a deep-sea vegetative layer to a shallow sea area, wherein the apparatus is connected to a plurality of intermittent air pumping apparatuses that discharge bullets intermittently and pump water.

The large cylinder in the above is, for example, a cylindrical or square reinforced concrete cylinder, which is self-supporting and can be a fish reef or a seaweed bed.

[0007] The lower end of the pumping cylinder of the intermittent air pumping device faces the upper part of the large cylinder (or in the auxiliary cylinder connected to the upper part). The air chamber of the pumping cylinder has a water depth of 20 m, for example.
Set up near.

[0008] The nutrient layer is often 200-400 m
In the deep sea, but it is difficult to construct a large cylinder from that depth to the shallow sea (for example, 100 m) .
It is difficult . Therefore to construct a large-cylinder to a length sufficient self installed on the seabed (e.g. 10 to 20 m), connecting the auxiliary cylinder, such that the upper synthetic resin, according to the auxiliary cylinder required 100
m is easy .

However, the pumping cylinder can be made to an arbitrary length (for example, 100 m) by means such as connecting a hose to the lower end.

[0010] Then the air chamber is not necessarily provided in the lower portion of the pumping cylinder, to provide maximum efficacy by minimal buoyancy
Can be provided on the upper part .

[0011]

According to the present invention, since the lower end of the pumping cylinder faces the inside of the upper part of the large cylinder, a part of the water in the upper part of the large cylinder is sucked up by the pumping cylinder, and the water pressure in this part is slightly lowered. Therefore, the water in the lower part is pushed up by the water pressure difference between the lower part and the upper part of the large cylinder, and an upward flow is generated.

[0012] Other portions partially sucked into the lifting water bottle of the upward flow is emitted from the upper end of the large-cylinder.

[0013]

[Example 1] Into a sea area with a depth of 200 m, a diameter of 5 m and a length of 30
m, a large cylinder 1 made of reinforced concrete is installed upright, and an auxiliary cylinder 2 made of FRP having a length of 70 m is connected to the upper part of the large cylinder 1. The inside of the upper part of the auxiliary cylinder 2 has a diameter of 50 cm and a length of 70 cm.
The lower end of the pumping cylinder 3 and fixed m, from the upper end of the pumping cylinder 3
The air chamber 4 is fitted and installed at a position 10 m downward . A suction port 5 is formed in a lower side wall (or an intermediate side wall) of the large cylinder 1, and a lower end is fixed to a foundation 6. The pumping unit 22 is constituted by the pumping cylinder 3, the air chamber 4 and the float 21 fixed to the pumping cylinder 3.

In the above embodiment, when pressurized air (for example, 4.2 kg / cm ² ) is injected into the air chamber 4, the water level 8 falls as indicated by the arrow 7 as the air accumulates in the air chamber 4. (FIG. 3). When the water level 8 reaches the water inlet 9 (water level 10 in FIG. 3), the air in the air chamber 4 is turned into arrows 11, 1
As shown in 2 and 13, the water is discharged into the pumping cylinder 3 at a time, and becomes an air bullet 14 and rises in the pumping cylinder 3. Then, the water in the auxiliary cylinder 2 is sucked in from the lower end of the pumping cylinder 3 as shown by arrow 15 and forms an upward flow, and is discharged from the upper end of the pumping cylinder 3 as shown by arrow 16 (FIG. 1). . In this case, the water temperature near the upper end of the pumping cylinder 3 is usually higher than the water temperature (5 to 10 ° C.) at the sea bottom (for example, 15
C. to 20 ° C.), which is enormous compared to the amount of water pumped, so that it is mixed, for example, to 14.5 to 19.5 ° C.
There, they diffuse radially as indicated by arrows 17 and 17 along the stratification by the seawater temperature. For example, water that has spread to the shore often travels straight until it reaches the shore, and then arrow 1
It reverses as shown by 8 and 19 and rises as shown by arrow 20 to form a vertical reflux.

Therefore, even in a place where high-temperature water is likely to settle on the water surface, such as in summer, water moves due to reflux by diffusion, and good results are obtained for the growth of seaweed and the growth of fish.

There are various types of fixing structures between the lower end of the pumping cylinder 3 and the auxiliary cylinder 2. For example, a ring 24 is formed at a central portion of a radial support rod 23 provided in a horizontal direction from the auxiliary cylinder 2. 24, the lower end of the pumping cylinder 3 is fitted and stopped by the retaining ring 40. When the pumping cylinder 3 is rotatably mounted, the pumping cylinder 3
Is always held vertically by the float 21. As described above, when the water in the auxiliary cylinder 2 is sucked, the water pressure in the auxiliary cylinder 2 and the water pressure difference between the lower part of the large cylinder 1 indicate an arrow inside the auxiliary cylinder 2 and the large cylinder 1. Ascending flows like 25 and 26 are raised, a part of which is sucked into the pumping cylinder as indicated by arrow 15 and the other part is discharged and diffused from the upper end of the auxiliary cylinder 2 to the outside as indicated by arrow 27.

[0017]

[Embodiment 2] In this embodiment, water from one large cylinder is diffused into a wide water area by a plurality of pumping devices. That is, the large cylinder 1 is installed on the foundation 6 along the seabed 28. Large cylinder 1
The lower end of the connecting pipe 29 is inserted into the opening, and the upper end of the connecting pipe 29 is connected to the distribution box 30. One end of a plurality of hoses 31a , 31b, 31c, 31d, 31e is connected to the distribution box 30, and each hose 31a, 31b, 31c, 31
The lower ends of the pumping cylinders 3, 3 are connected to the respective ends of d, 31e.

In the above embodiment, each pumping device 22, 2
When the pressurized air is sent into the air chambers of the second embodiment, respectively,
As explained in the above, the air bombs are discharged intermittently and the pumping cylinder 3
Cultivate an upward flow into the interior. Then the hoses 31a, 31b,
Since the water in the distribution box 30 is sucked through 31c, 31d and 31e as indicated by the arrow 32, the water in the distribution box 30 is also sucked out. When the water in the distribution box 30 is sucked out, the water in the connecting pipe 29 flows as indicated by an arrow 33, and as a result, the large cylinder 1
Will suck up the water inside the top. When the water inside the upper part of the large cylinder 1 is sucked up, the water in the large cylinder 1 becomes
4 ascending flow, a part of which is sucked into the connecting pipe 29,
The other part is discharged from the upper end of the large cylinder 1 to the outside as indicated by arrow 38. Thus, if the water pressure at the upper end of the large cylinder 1 decreases, the large cylinder 1
As shown by an arrow 35, the air is sucked from the suction port 5 provided at the lower end of the. In the figure, 36 indicates a nutrient layer surface, and 37 indicates a water surface.

Each of the hoses 31a, 31b, 3
The water sucked up by 1c, 31d, and 31e diffuses radially from the upper end of each pumping cylinder 3, and is indicated by a chain line 39 in FIG.
Water area. By arranging the Supporting connexion pumping cylinder 3 at appropriate intervals (e.g., 400m intervals), it can be in waters 628,000 m ² by five pumping cylinder to diffuse nutrient water water of predetermined depth.

The power source in the above is pressurized air sent to the air chamber 4 of each pumping cylinder 3, and the other is an upflow utilizing the buoyancy and water pressure difference of air bullets generated by the air. Therefore, you will do the largest job with the least energy.

[0021]

According to the present invention, as a result of spreading eutrophic seawater on the seafloor side into shallow waters, a slow water flow (up and down reflux) is generated in the shallow waters, and nutrients and oxygen are supplied to fish and seaweeds. And the addition of oxygen to the microorganisms in the shallow seafloor to help them to proliferate, whereby aerobic bacteria can decompose organic matter on the bottom and clean up the shallow bottom. There are various effects such as playing.

Further, as described above, the distribution of nutrients is made possible by the fluidization of seawater, which has the effect of preventing aging of the sea area, which is likely to occur on marine pastures. The eutrophicized seawater has the effect of rising not only from the pumping cylinder but also from the mouth of the large cylinder and diffusing above the eutrophic layer.

In high-density rabbit horn culture, there is a problem that fish and the like are susceptible to disease. However, according to the present invention, there is no such danger, and eutrophic water on the bottom of the sea is diffused into shallow waters. In addition, there is also an effect that fertilization or feeding to fish can be achieved, or even if feeding is small, the purpose of a marine ranch can be achieved.
