Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the purpose of storing contents (fish and shellfish) in a living basin, submerging the contents on the sea floor and cultivating the contents, and maintaining the inside of the living basin in the best environment for a long time. In addition to measuring the growth and growth of the contents, it is possible to simplify the farming equipment, materials and work styles, and therefore, it is a mobile installation type that does not require the seafloor installation conditions. Things.

[0002]

2. Description of the Related Art Heretofore, this type is as follows. Conventional methods of promoting the growth and growth of contents (seafood) by cultivation include the use of a floating marine ball on the sea surface, such as a “marine raft-style living net” surrounded by a frame with a floating ball, or a floating rope on the sea. A method of suspending and storing net bags or baskets that store contents called "pockets" underwater in a lot of facilities called "noshi", and a "stationary bottom construction net" where a net enclosure is installed and farmed on the sea floor. And farming of seafood. Any of the farming facilities is of a fixed installation type that cannot be easily moved once installed.
In addition, there are cases where the contents are stored and cultivated at one time in containers and baskets made using various materials for the purpose of catching catches, but for the purpose of promoting long-term growth and growth. is not.

[0003]

The above-mentioned prior art has the following problems. Farming facilities using net bags and net baskets, called “marine raft nets” installed on the sea surface or “pockets” suspended from the sea surface into the sea, change weather conditions, change in ocean currents, and tides. (If the net bag or net basket suspended under the sea due to low tide reaches the seabed, the contents often die.) It has disadvantages that are easily limited. In addition, enormous materials and funds and a large number of human labor are required to prevent the outflow of facilities, and since the management and operation of the facilities also require funds and labor, the production cost of seafood is reduced. Soaring prices have significantly worsened profit margins with sales prices.
In addition, since the fixed installation type facilities are installed using the sea surface, taking up space on the sea surface also hinders navigation of ships. It should be noted that farming by the “fixed bottom construction net method” is also as described above. With the above-mentioned conventional farming facilities, fish net materials are mainly used on the sea surface and the sea floor, and work is carried out to promote the growth and growth of the contents in the living basin fixed on the sea surface limited for many years. , The waste that is excreted on the sea floor accumulates, adversely affects the fish and shellfish due to weather conditions, and in some cases shakes the management base of the producer due to mass mortality, and the management crossroads must be constantly considered . In addition, the larger the facility, the more difficult it is to respond to changes in weather conditions and ocean currents unless large-scale items are used due to the facility materials and attached equipment. Many are rejected, requiring enormous financing in inverse proportion, so that the investment capital and the return on production and sales amounts do not match the ratio. The present invention has been made in view of such problems of the conventional technology, and has as its object to provide the following. That is, the present invention fundamentally improves the form and configuration of living tanks required for cultivating the contents (fish and shellfish) except for the above-mentioned drawbacks, reduces facility funds and management costs, and reduces production costs. In addition to lowering the cost, one person can easily install and move the apparatus in a short period of time, and the production cost is further reduced, so that the producer can obtain more profit and provide a stable business environment. In addition, because it is possible to move and install, unlike the type of living tank of the fixed facility method, the environment of the seabed is constantly optimized by dispersing the accumulation of waste excreted during the growth and growth of the contents to a certain place on the seabed. And provide farm facilities that are not affected by weather conditions.

Since the present invention is configured as described above, it has the following effects. A. Conventional arranging tanks have a large amount of main materials for molds and frames that support the net and nets on the sea surface and the sea floor, and a large amount of auxiliary materials such as floating balls and equipment, to firmly fix and install facilities, Weather conditions,
In addition to considering the strength of ocean currents and changes in tidal range, etc., we have a large number of people and installation preparation period for facility installation work regardless of the size of the facility, so we spend various expenses and until the facility is installed This is a farm that requires enormous funds and requires more management and labor after the facility is installed. On the other hand, since the seabed-mounted non-falling living tank 1 of the present invention is a composite living tank using the shape and structure of a container that can be moved under the seabed, there is no need for materials such as molds and frames. Since only a small amount of auxiliary materials such as floating balls and equipment are needed, and it is not necessary to provide solid facilities, weather conditions, strength of ocean currents, changes in tides,
Furthermore, the geology, topography, etc. may be taken into consideration at a minimum, and one person can perform the same work for facility installation in a short time regardless of the size of the facility. As a result, there is no need for any period or expenses for the preparation of the facility installation, so only a small amount of funding is required for the facility installation.Furthermore, only a little management and labor is required after the installation, and the farmer has no labor. It can reduce the time and leisure of time, and improve the renovation. B. When the contents are stored in the seabed-installed non-inverted living basin 1 of the present invention and submerged on the seabed for growth and growth, the lid of the opening 4B2 provided on the top plate of the upper wall 4 is opened, and the contents are opened. To store. When sinking from the sea to the seabed, seawater flows in through a seawater inflow / outflow hole 2A1 provided in the lower wall portion 2. The seabed-mounted non-overturning living room tank 1 of the present invention starts sinking in a vertical state due to the gravity of the weight 2D. Next, the seawater filled with water in the lower wall portion 2 is guided into the seawater inflow / outflow guide pipe 3B of the inner wall portion 3, becomes pure seawater by the small holes 3B21, flows into the upper wall portion 4, and becomes full. It will sink into the seabed and be installed vertically. C. A bent narrow wall 4A1 is formed on the side wall 4A of the upper wall portion 4 of the seabed-installed non-falling living basin 1 of the present invention installed vertically on the sea floor, and the bent narrow wall has a hole 4A2 for seawater inflow and outflow. Is provided, turbulence is generated in the seawater, and a large amount of seawater flows uniformly into the upper wall from the entire peripheral surface of the upper wall, and then flows out from the upper wall to the outside. Thereby, the inside of the thing of the present invention can keep the fresh seawater condition constantly, and can provide the best environment for growth and growth promotion by long-term cultivation of the contents. D. There is a possibility that the seabed-mounted non-overturning living basin 1 of the present invention installed on the seabed may be drained by the tide, but this has been previously fixed on land.
Can be connected to a circular ring fitting 2A2 provided on the lower wall 2 in a face-to-face manner by a rope of a fixed length to prevent outflow. E. FIG. When a plurality of submarine-installed non-falling living tubs 1 of the present invention are installed on the seabed, a fixed length rope is provided between the submarine-installed non-falling living tub 1 and the submarine-installed non-falling living tub 1 By repeating the connection to the ring-shaped bracket 2A2 by using, the chain can be installed without any restriction. This allows one person to easily repeat the same operation in a short time. F. By connecting the rope connected to the floating ball to the round ring metal fitting 2A2 for the purpose of lifting the installed seabed-mounted non-falling living room tank 1 of the present invention to the sea, all the countless seabeds of the present invention can be easily obtained. The stationary tank 1 and the anchor (anchor) can be lifted to the sea and the land at once by using a device such as a hoisting drum. G. FIG. The biggest problem in the process of growing and growing the contents in farming is the treatment of waste excreted from the contents. The filth tends to flow downward from the upper side of the conical wall 3A of the inner wall 3 and is constantly concentrated on the lower circumferential corner. In addition, the seawater inflow / outflow guide pipe 3B has an adjustment blade 3C.
Since the sewage is provided in the vertical direction, the sewage is prevented from floating and diffusing, which occurs inside the sewage of the present invention due to the change in the strength of the ocean current, and is constantly deposited on the upper wall of the conical wall 3A quickly to improve the sewage. It can flow down from the direction surface to the lower surface, and can be automatically and reliably discharged in a short time from the waste discharge groove 3D provided on the lower circumferential corner surface. As a result, the filth which is installed on the sea floor for a long time and whose contents are excreted does not accumulate on the upper surface of the conical wall 3A, and is automatically and reliably discharged to the outside. Does not occur. Further, the filth discharged outside diffuses the turbulence of the seawater generated by the side wall 4A of the upper wall portion 4 due to the shape of the plane gear and the accumulation on the seabed by the shape of the lower wall portion 2, and the periphery of the present invention. Also prevents the spoilage of filth,
It is possible to eliminate the harmful effects of decay of contents caused by decay of filth. H. The reason for the non-falling state is as follows. FIG.
As shown in FIG. 8, when the center of gravity G of the weight 2D and the fulcrum P of the bottom 1 are vertical, the moment is 0 and stable, but as shown in FIG. The living tank 1 is tilted, and the seabed-installed non-falling living tank 1
When the fulcrum moves from P to P ', a moment of W x P'P "is generated and the fulcrum tries to return to P. Even if the state of the ground contact surface is not uniform, the seabed-mounted type falls down front and back and left and right due to the water current. The living tank 1 is shaken and eventually approaches the most stable vertical state, where G is the center of gravity of the weight 2D, and P is the vertical, seabed-mounted, non-overturning living tank 1. , The fulcrum of P 'is the fulcrum of the tilted sea-bottom-installed non-inverted living tank 1, W is the weight of the weight 2D, and P "is the intersection of the horizontal line passing through the fulcrum P' and the perpendicular passing through the center of gravity G.
