Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for cultivating plants which can be used on the surface of seawater.

[0002]

2. Description of the Related Art Conventionally, plant cultivation on the surface of seawater has not been devised in consideration of salt damage. The method of reclamation requires large-scale construction such as building a dike, pumping seawater, and putting soil for cultivation. In addition, offshore power generation is considered to be carried out by mounting a photovoltaic power generation panel on a device such as a ship or raft, but independent power generation has a problem in terms of profitability.

[0003]

[Problems to be Solved by the Invention] Without requiring large-scale construction that has a great impact on the environment such as reclamation,
Plants can be cultivated on the surface of seawater, and rainwater and dew condensation water can be collected and stored using a solar power generation panel, which enables long-term unsupplied water supply and the generated electricity supplies oxygen to the sea. Provide a plant cultivation device which can be used for electrolysis of seawater and seawater, and is naturally friendly and highly economical even on the surface of seawater.

[0004]

[Means for Solving the Problems] (a) According to the present invention, the floor for crop cultivation is floated on the surface of seawater, and dew condensation water and rainfall can be stored for long-term waterless cultivation. (B) In the present invention, by using a solar power generation panel having a function of collecting rainwater and generating electric power, a large-scale solar power generation space using the sea surface can be secured for crop cultivation. (C) According to the present invention, a remote control device or an automatic buoyancy adjusting device is attached to a cultivation floating floor, the sea surface can be freely moved, and a large area can be collectively centrally controlled to greatly improve productivity.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

(A) FIG. 1 is a sectional view taken along the short side of the present invention. The box-shaped cultivation floating floor (1) divided in the long side direction is mainly intended for cultivation of plants on both sides, and a seawater intake tank (2) for taking in seawater in the central part to stabilize the cultivation floating floor. And a cultivation layer (6). (B) The upper part of the seawater intake tank (2) in the central part is arranged with a roof of a gable-type photovoltaic power generation panel (7) for solar power generation, and rainfall is stored in the water storage tanks (4) on both sides and the water intake plate. Store through (8). During fine weather, the water temperature of the seawater intake tank (2) rises and a large amount of water vapor is generated, and during the daytime and at night, dew condensation occurs on the back surface of the photovoltaic power generation panel (7) and the water storage tank (4) passes through the intake plate (8). Accumulate in. The seawater intake tank (2) has a small seawater passage hole (2
Since the seawater enters through 1), the temperature rise of the seawater is large and the condensed water is easy to collect. For the replenishment of water during the period until the roots of the crops reach the water tank, the moisture absorption pumping material (14) absorbs water to moisten the culture soil. In addition, for rising in strong wind,
It has the effect that the seawater inside becomes a weight and works. (C) A buoyancy adjustment tank (3) that automatically adjusts the ups and downs of the cultivation floating floor by sending air from the blower branch pipe to the bottom of both sides by the function of the draft adjustment sensor (11), and rainwater and condensation water in the middle part A water tank (4) for storing cultivation water, an air layer (5) for preventing root rot of the root part of the crop, a net for cultivation soil (13) laid on top, and cultivation soil (1)
There is a cultivation layer (6) for growing 8). Further, a salt damage prevention enclosure (15) can be attached to prevent salt damage by wind or the like.

FIG. 2 is a perspective view of the stand-alone device of the present invention.

FIG. 3 is a perspective view of the apparatus of the present invention assembled and connected. A single cultivation floating floor (1) is sown with a seed of a crop and connected to a management piping duct (10) connected to a management main box (9) equipped with a propulsion device that can be operated remotely, and is assembled into a large block, Air is sent to each partitioned buoyancy adjustment tank (3) via the draft adjustment sensor (11) to maintain the draft level, and an instruction radio wave from the central control building is received by the receiving antenna (19) to remote the propulsion unit. It can be operated to freely move the water surface, enabling centralized management of large areas.

FIG. 4 is a perspective view of the stand-alone device of the present invention seen from the bottom side. The bottom of the box-shaped cultivation floating floor (1) divided in the long side direction has a seawater intake tank (2) with a seawater passage hole (21) in the center and air from a blower branch pipe (23) on both sides at the bottom. The buoyancy adjusting tanks (3) for feeding up and down to adjust the ups and downs of the cultivation floating floor are divided into four, and the cultivation floating floor (1) can be always kept horizontal by adjusting the automatic pressure of each individual.

[0010]

The present invention is carried out in the form as described above, and exhibits the effects as described below. (A) A vast area of the sea is surrounded by a breakwater, and natural environment such as reclamation is greatly expanded. Without changing, fisheries can be performed as usual and agricultural products can be cultivated. (B) By using a solar power generation panel on a roof that collects rainwater to generate electricity, a large-scale solar power generation space using the sea surface can be secured for crop cultivation. (C) By attaching a remote control device or an automatic buoyancy adjusting device to the cultivation floating floor, and freely moving the water surface, the vast area can be centrally managed collectively and the productivity can be greatly improved.
