Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and a method for culturing seaweed, and more particularly to an apparatus for floating and sinking the apparatus on the seabed and a method for cultivating seaweed using the apparatus.

[0002]

2. Description of the Related Art Conventionally, when cultivating seaweed, a method has been adopted in which a rope is tightly connected between two supports and a seed of seaweed is planted on the rope for cultivation.

[0003] However, according to this method, it is necessary to insert the support rods each having a rope in which the seeds of the seaweed are planted into the sea one by one, so that it takes much time and effort, and the production efficiency is not good.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention reduces the time and effort required to insert struts tied with ropes planted with seaweed seeds into the sea one by one, shortens the time, and further improves production efficiency. It is an object of the present invention to provide an apparatus and a method for improving the production and increasing the production amount.

[0005]

In order to achieve the above object, an apparatus according to the present invention comprises a plurality of columns having a hollow inside and a lid provided on an upper portion, and a plurality of columns fixed between the columns. And a plurality of ropes tied between the bars.

Since the inside is hollow and has a lid, a liquid such as water or air can be introduced into the column by opening the lid, and as a result, the culture apparatus of the present invention can be made to float. You can do it.

It is preferable that the number of the columns is four, that the columns have a truncated cone shape in order to stabilize the columns, and that the columns and the rods are made of metal.

[0008] Furthermore, the installation of the floating and sedimentation type seaweed cultivation apparatus of the present invention needs to be in a range where light can reach and in a range that is hardly affected by waves.
It needs to be in the range of m to 25 m.

Further, in order to achieve the above-mentioned object, in the culture method of the present invention, there is provided a method for planting seaweed seeds in the rope, the method comprising: A step of submerging the floatation type seaweed cultivation apparatus on the seabed 10 m to 25 m above the sea surface by putting a liquid with a hose, a step of submerging the floatation type seaweed cultivation apparatus on the seafloor for a certain period during which the seaweed grows, When the cultivation is performed, a step of removing the lid of the column, injecting air into the column, and floating the floating sedimentation apparatus to the sea by the force of the air.

It is preferable that the means for introducing air into the column is a compressor and the liquid is water.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a view showing a view in which a floating-season type seaweed cultivation apparatus of the present invention is installed on the sea floor, in which four pillars 1 in the form of truncated cones are shown, and a plurality of rods 3 are provided between the pillars 1. In this drawing, three rods 3 are fixed, and a rope 4 is vertically and horizontally fastened to the rods 3 between the rods 3, and the columns 1 and the rods 3 are made of metal. It is.

A lid 2 is provided on the upper portion of the column 1, and the lid 2 is fixed to the upper portion of the column main body so that the lid 2 does not fall when the lid 2 is opened as shown in FIGS. It is stopped at 10 and the inside of the four columns 1 is hollow so that water or air can be introduced. A seaweed seed 8 such as a kelp seed is planted on a rope 4 tied lengthwise and breadthwise.

FIG. 2 shows a floating-season type seaweed cultivation apparatus according to the present invention.
FIG. 4 is a view showing a state in which water is being poured into the hollow space inside one of the columns 1 and is going to be submerged on the sea floor, and the lid 2 of the column 1 is opened, and water is poured into four columns by a rubber hose 5 provided on a ship 7. The floating and sinking type seaweed cultivation apparatus of the present invention sinks into the sea due to the weight of the water. When sinking in the sea, it is within 10m, where the sun's rays reach and are hardly affected by the waves
~ 25m below sea level.

FIG. 3 is a view showing a state in which the floating / sedimentation type seaweed cultivation apparatus of the present invention is to be floated from the sea, and air is supplied to the cavities inside the four columns 1 by the compressor 6 installed in the ship 7. Put in. At this time, the water in the column 1 is pushed out by the force of air, but the weight of the air is used to float the floating / sedimentation type seaweed cultivation apparatus of the present invention.

When water and air are introduced into the column 1 with the rubber hose 5, the work of opening the lid 2 of the column 1 and inserting the rubber hose 5 into the column 1 is performed by a diver.

It is the seaweed 9 that makes the floatation type seaweed cultivation apparatus float from the sea floor, for example, in the case of kelp, the seaweed seed 8 is the seaweed 9
It has been about two years since it has grown. Then, the seaweed 9 grown by the fisherman may be collected.

[0017]

As described above, the present invention has the above-mentioned structure, so that the production efficiency and the production amount of seaweed can be increased without the need for a large-sized machine, and without any labor and time.
