Description

Underground fishery using air dome using air dome

The present invention relates to an underground buried fish farm using an air dome, and more particularly, to reduce the energy cost by utilizing the heat inside the air dome installed for cultivating crops to maintain a water temperature suitable for culturing fish. And a ground-buried fish farm in which an air dome is buried in the ground of a site where a separate farm site is not necessary.

Generally, vegetables and fruits, crops, horticultural crops, mushrooms, etc., are planted in a facility house such as a vinyl house which maintains indoor temperature appropriately in order to cultivate the crop irrespective of seasonal changes of the external environment. Let it be harvested.

In agricultural production facilities such as vinyl houses, the energy emitted by the sun during the day is directly used by crops for photosynthesis and accumulated in the ground or other materials capable of accumulating heat and used for heating. Depending on the crops being cultivated, heating or cooling facilities are installed inside to maintain a suitable temperature inside the house.

Recently, crop cultivation facilities using air dome have been used.

The air dome is a structure in which air is injected into the space between the inner skin and the outer skin after closely fixing the double structure wall made of the inner skin and the outer skin to the ground. The air dome has the advantage that it can improve the workability and reduce the construction cost, and can freely design the size and shape according to the installation place. These air domes have been mainly used as simple facilities for building structures (exhibition halls for various events), but recently they have been used as facility houses for cultivating crops.

Korean Patent Laid-Open No. 10-2015-0039244 discloses an air dome house which maintains a dome shape as an air infusion. Such an air dome house is suitable for use as a facility house for crop cultivation such as a mushroom grower since a greenhouse space is provided inside.

However, there is a problem in that when the natural heating by the solar light or the separate heating or cooling system is operated in the air dome to cultivate the crop, a lot of heat is lost to the ground.

Korean Patent Publication No. 10-2015-0039244: Air dome house

The present invention has been made to overcome the above problems, and it is an object of the present invention to provide a fish farm in the lower part of an air dome to maintain a water temperature suitable for culturing fish by utilizing the heat transmitted from the inside of the air dome to the ground The aim is to provide an underground buried fish farm with an air dome that can save a lot of energy costs and does not require a separate farm site.

In order to achieve the above object, an underground buried fish farm using an air dome of the present invention is formed as a double structure consisting of an inner membrane and an outer membrane which surrounds the inner membrane and is spaced apart from the inner membrane by a certain distance, An air dome provided with a cultivation space for growing crops; And a fishponding unit embedded in the ground located below the cultivation space and capable of controlling the temperature of water by heat transmitted from the cultivation space.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an underground buried fish farm using an air dome according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 to 5, a fish farm according to an exemplary embodiment of the present invention includes an air dome 10 and a fish-friendly unit.

The air dome 10 is formed on the ground so as to surround the cultivated land 1 in which the crop is grown in a dome shape. The lower portion of the air dome 10 is embedded in the ground to a certain depth. The air dome 10 is formed in a double structure composed of an inner film 11 and an outer film 15 surrounding the inner film from the outside. The outer film 15 is spaced apart from the inner film 11 by a certain distance. The inner film 11 and the outer film 15 may be made of a light transmitting resin that can transmit sunlight. The inner film 11 and the outer film 15 of the air dome can be supported by a rope or a lightweight frame. It is a matter of course that the illustrated air dome 10 may be provided with an air injection device for injecting air into a space between the inner film 11 and the outer film 15 in a conventional structure. Further, an entrance can be formed on the front and rear surfaces of the air dome 10.

Inside the air dome (10), a cultivation space (17) for cultivating crops is provided. A crop can be planted on the ground on which the cultivation space 17 is located, that is, the cultivated land 1. In addition, it is needless to say that the crops can be cultivated by installing facilities necessary for crop cultivation in the cultivation space 17. A separate heating or cooling system may be installed to artificially heat or cool the cultivation space 17 of the air dome 10. [

The fishfield unit is buried in the ground located in the lower part of the cultivation space (17).

In the present invention, since an aeration unit is installed under the ground where the air dome 10 is installed, it is not necessary to secure additional ground in addition to the air dome ground. In addition, the heat inside the air dome 10 can be utilized to maintain the water temperature suitable for culturing the fish, thereby greatly reducing the energy cost.

Aquaculture units are cultured with circulation of water. The water that can fish the fish is advantageous in that the temperature is constantly controlled by the heat transmitted from the cultivation space of the air dome 10. [ For example, in winter, heat is transferred from the warm air that warms the cultivation space 17, and in the summer, heat is transferred from the cool air that cools the cultivation space, so it is very easy to maintain the water temperature suitable for the fish culture.

The water supply unit 20 includes a water treatment unit 20 for water treatment of the water introduced into the water tank unit 20 and a water treatment unit 20 connected to an outlet of the water treatment unit 20, (50), one side of which is connected to one point of the circulation line (50) and the other side of which is connected to another point of the circulation line (50) And a plurality of branch lines 70 for distributing a plurality of branch lines 70 in the path.

The water treatment section 20 serves to purify the water quality by treating the pollutants contained in the water in which the fish are cultured.

The water treatment section 20 includes a settling tank 21 into which water to be cultivated by the fish flows, a filtration tank 25 into which water discharged from the settling tank 21 flows and is filtered, A microbial treatment tank 40 for introducing water into the microbial treatment tank 40 for decomposing contaminants by microorganisms and a storage tank 45 for allowing water discharged from the microbial treatment tank 40 to flow therein.

The settling tank 21 is formed into a square tubular shape. At one side of the settling tank 21, an inlet port is formed which is connected to the reduced-diameter pipe 55 of the circulation line. The inlet may be equipped with a blocking net to prevent entry of fish. The water introduced into the settling tank 21 flows into the filtration tank 25 through the connection hole 24 formed in the upper part of the first bank 23. The foreign matter is precipitated by the difference in specific gravity in the settling tank (21).

A rectification plate 26 is vertically installed in the filtration tank 25 to divide an internal space of the filtration tank 25 into an inflow space 28 and a filtration space 29. The lower end of the flow regulating plate 26 is spaced from the bottom of the filtration tank 25. A baffle 27 is formed on the side surfaces of the rectification plate 26 and the first bank 23 facing each other at regular intervals in the vertical direction. The water that has passed through the inflow space portion 28 flows into the filtration space portion 29 to form an upward flow. The filter space portion 29 is provided with two filter portions 30 for filtering water.

Each of the filter units 30 includes an upper porous plate 31 and a lower porous plate 33 which are vertically spaced apart from each other, and a filter member 35 accommodated between the upper porous plate and the lower porous plate. Activated carbon, gravel, sand, porous ceramics, etc. may be used as the filter medium 35.

The water having passed through the filter unit 30 flows into the microbial treatment tank 40 through the connection hole 39 formed in the upper part of the second partition wall 37. The microbial treatment tank 40 decomposes various organic substances contained in water by using microorganisms.

The microorganism treatment tank (40) is provided therein with a microorganism carrier (41) in which microorganisms are inhabited. The microbial carrier may be supported on a support bar across the interior space of the microbial treatment tank. As an example of the microorganism carrier 41, a microorganism supported on a fibrous filter material may be used. Needless to say, various known water treatment carriers can be used, unlike the microbial carrier 41 shown in FIG. The microorganism carrier 41 decomposes contaminants such as various organic substances, ammonia, nitrite, nitric acid, and nitrogen contained in water flowing into the microbial treatment tank 40 to purify water quality.

The purified water in the microbial treatment tank 40 flows into the storage tank 45 through the connection hole 44 formed in the upper part of the third partition wall 43. On the side surface of the storage tank 45, an outlet connected to the enlarged view pipe 51 of the circulation line 50 is formed. The outlet may be equipped with a blocking net to prevent entry of the fish. The purified water through the outlet is introduced into the circulation line (50).

The circulation line (50) connects the outlet of the storage tank (45) and the inlet of the settling tank (21) to each other. Therefore, the purified water in the water treatment section 20 flows into the settling tank 21 via the circulation line 50, and is continuously circulated. The fish being cultured is swimming along the circulation line (50).

The circulation line (50) is installed along the periphery of the cultivated area enclosed by the air dome (10). The circulation line 50 can be installed at a depth of about 20 to 100 cm from the surface of the cultivated land 1.

The circulation line 50 is formed by alternately arranging the enlarged scenery 51 and the reduced scenery 55. In the illustrated example, an extension pipe 51 is first connected to the outlet of the storage tank 45. And a reduced landscape 55 is connected to the expanded landscape 51. [ And the enlarged landscape is connected to the enlarged landscape again. That is, the expanded landscape and the reduced landscape are alternately connected in the order of the expanded landscape-reduced landscape-expanded landscape-reduced landscape. Alternatively, the reduced landscape and the expanded landscape can be alternately connected in the order of reduced landscape-expanded landscape-reduced landscape-expanded landscape-reduced landscape. The extended pipe 51 may be, for example, a pipe having a diameter of 450 mm and a length of 6 m. The reduced diameter pipe 55 may be a pipe having a diameter of 200 mm and a length of 5.6 m.

Thus, the circulation line 50 is formed by alternately arranging the enlarged scenery 51 and the reduced scenery 55, so that the water flowing inside can be alternately compressed and expanded. The inner diameter of the enlarged view pipe (51) is formed larger than the inner diameter of the reduced diameter pipe (55). As the water passes through the enlarged pipe 51, the flow velocity is lowered and the pressure is increased. And then, as it passes through the collapse scenery 55, the flow velocity increases and the pressure decreases. As the water passing through the circulation line 50 is alternately compressed and expanded repeatedly, mixing of water and air is efficiently performed. In addition, it prevents the foreign matter from sticking to one place by changing the flow rate.

One end of the multiple branch line 70 is connected to one point of the circulation line 50 and the other end thereof is connected to another point of the circulation line 50 to disperse the water flowing through the circulation line 50 into a plurality of paths. For example, when the circulation line 50 is installed in a rectangular shape along the edge of the cultivating area 1 as shown, the multiple branching line 70 is installed across the cultivating area. The multiple branch lines 70 are arranged in parallel with each other by a predetermined distance.

The multiple branch lines 70 are embedded in the basement of the same depth as the circulation line 50. That is, the multiple branch lines 70 can be installed at a depth of about 20 to 100 cm from the surface of the cultivated land 1.

The multiple branch line 70 is formed by alternately arranging the extended landscape 71 and the reduced landscape landscape 75. This is the same as the circulation line 50.

On the other hand, the ground connection channel unit 80 is further provided in the fish-mouth unit.

The ground connection channel unit 80 serves to connect the multiple branch line 70 and the cultivation space 17 of the air dome.

At least one or more ground connection channel units 80 may be installed at predetermined intervals along the longitudinal direction of the multiple branch lines 70. The ground connection channel unit 80 may be connected to the enlarged landscape 71 of the multiple branch line 70 or may be connected to the reduced landscape 75.

The ground connection channel unit 80 is composed of a pipe connected to the multiple branch line 70 at the lower part and exposed to the cultivation space 17 at the upper part. The ground connection channel portions 80 are provided so as to be inclined in a direction in which the pairs of the ground connection channel portions 80 are widened. That is, the pair of ground connection channel portions 80 are formed in a V-shape with a narrow gap at the bottom and a wide gap at the top.

Feeding the feed into the multiple branch line (70) through the ground connection channel unit (80) and simultaneously introducing air and heat.
