Description

[0001] The present invention relates to a device for forming a water surface in water,

The present invention relates to an aquaculture apparatus having a water surface in water, more specifically, an air collecting unit formed in a cover shape so as to have a space portion opened at a lower surface thereof, a mesh unit connected to a lower portion of the air collecting unit, Wherein the air is supplied to the air collecting part to form a water surface in the water forming the air layer.

There are many ways to grow aquatic organisms, but among them, caged aquaculture is a typical example of providing aquatic organisms by separating them from other sleeping areas by installing certain facilities on a private water surface designated as a shared or developed area.

The cage culture has a problem in that a large amount of excrement is generated in the process of culturing aquatic organisms, and water scum is caused by the formation of debris by the residual feed. Specifically, excreta and feed contain a large amount of phosphorus, which is a major cause of eutrophication beyond simple water pollution.

On the other hand, even if the water flow is not smooth and the water temperature rises, the eutrophication of the seawater is promoted and the oxygen is easily exhausted.

Specifically, the reduction of 0.1 ppm based on BOD, which is an index of water pollution, is required to reduce pollutants by approximately 11 tons, and the pollutant load generated in domestic cage farms is estimated to reach 20 tons per day.

As a prior art document for solving these problems, Korean Patent Laid-Open No. 10-2014-0046497 (published on April 21, 2014) and the like have been proposed, and the above-mentioned prior art documents have been proposed in an environmentally friendly manner And to provide a marine cage farm which can supply air by itself.

Although the above prior art documents can partially solve the problems of water pollution and eutrophication based on continuous air supply, it is still inevitable to carry out cage culture with the sea surface exposed at the upper part. As in the conventional cage culture facility, They had to react sensitively to conditions, water temperature and water quality.

Therefore, there is a problem that the cage culture facility formed on the surface due to a typhoon or a strong storm is easily damaged or lost, and the water temperature is sensitive to the outside air.

In addition, there is a difficulty in using only the same cage aquaculture facility, so that irrigation can be performed irrespective of the type of fish, or only a limited type of fish can be cultured.

Furthermore, the phenomenon of eutrophication spreads widely according to the flow of water, and once the eutrophication phenomenon occurs, the problem of water pollution by cage culture can not be solved fundamentally.

Embodiments of the present invention will now be described with reference to the accompanying drawings.

FIG. 1 is a perspective view showing the overall shape of a water producing apparatus F in which a water surface is formed in water according to an embodiment of the present invention. The water producing apparatus F is entirely provided in water, A mesh unit 200, an air generating unit 300, and a position fixing unit 400.

The air collecting unit 100 is configured to form an air layer and has a cover shape so as to have a space 110 in which a bottom surface is opened. Accordingly, the air collecting unit 100 may be formed in a dome or a shell shape as well as a polyhedron or a polygonal pyramid if the lower surface of the air collecting unit 100 is in a closed shape as a whole.

The air collecting part 100 may be formed of a metal material such as a steel plate or a synthetic resin material so as to prevent damage or deformation due to water or external force and it is important to provide an airtight space so that the air layer AL does not escape to the outside Do.

The mesh unit 200 is coupled to the lower part of the air collecting unit 100 so as to have the aquatic environment 210 in which aquatic organisms can live.

The mesh unit 200 may be formed using a known mesh network. The mesh unit 200 may include a structure in which a mesh is formed on the bottom surface so that aquatic organisms are not separated, It is possible.

The method of connecting the mesh unit 200 to the air collecting unit 100 may be performed by various known means. By connecting the mesh unit 200 along the outer circumference of the bottom surface of the air collecting unit 100, It is preferable to make it so that aquatic organisms can touch the water surface.

The air collecting unit 100 includes an air generating unit 300 that directly supplies air to the space below the air collecting unit 100 to supply air to the space 110 of the air collecting unit 100, And is collected to form the air layer AL.

The air generating unit 300 may provide air in various ways, but it is preferable to produce air using the air pump 310. The air generating unit 300 may be configured to construct the self-generating unit 330 to supply power to the self-generating unit 330, or may be designed to operate the air generating unit 300 based on external power.

In addition, a position fixing unit 400 is formed to fix the mesh unit 200 at a predetermined position in water so that the aquaculture apparatus F installed in the water is provided at a predetermined position from the flowing water.

The position fixing unit 400 may be fixed to the bottom surface of the mesh unit 200 directly by a cable or by using an anchor to secure the bottom surface of the mesh unit with a cable, or by forming a frame on the anchor, Method can be used.

However, in order to flexibly adjust the water depth of the aquaculture apparatus F having a water surface in the present invention, the mesh unit 200 is connected to a cable so that the mesh unit 200 is not separated from the cable However, it is preferable to make it float in water.

Thus, the aquaculture apparatus (F) in which the water surface of the present invention is formed can be provided in the water as a whole without being exposed to the water surface, so that the aquaculture apparatus can be safely protected in spite of a sleeping environment caused by a hurricane or a storm And even if the internal water quality of the aquaculture apparatus F is somewhat contaminated, it is possible to solve the problem that the water is positively propagated to the outside through the water surface.

Meanwhile, the air collecting unit 100 may have a plurality of air outlets 120 along a side surface at a predetermined height. The air supplied from the air generating part 300 reaches the air collecting part 100 to form the air layer AL so that air can not be formed below the air outlets 120, ). &Lt; / RTI >

Thus, the height of the air layer AL can be kept constant, and the fact that the thickness of the air layer AL is constant means that the buoyancy applied to the aquaculture system F is constant, Can be controlled.

At this time, the air outlet 120 is formed at a predetermined height along a side surface to form a plurality of air discharge outlets 120 having a height different from that of the air discharge layer 120a. The height of the air layer AL can be adjusted by forming the second air releasing layer 120b.

If the air collecting part 100 is positioned at a deeper water depth or at a shallower water depth than in the conventional case when a plurality of air emitting layers 120a and 120b are formed, And the second air chamber outlet 120b located below the second air chamber outlet 120b are mutually opened and closed, the thickness of the air layer AL can be flexibly adjusted.

Accordingly, when the depth of the air trapping part 100 is desired to be changed, the opening and closing of the air release layer 120a and 120b are changed so that the position can be more easily moved.

Although it is obvious that two air discharge layers 120a and 120b may be formed, it is obvious that the air discharge layers 120a and 120b may be formed of more than two layers. In opening and closing the air discharge port 120, It is also possible to manufacture the switch to operate automatically by opening and closing.

As shown in FIG. 4, the air collecting unit 100 may include a food supply unit 130 for supplying food to aquatic organisms. The food supply unit 130 may include a food box 131 and a food supply port 132. The food box 131 may include a liquid type food as well as a solid food, The food supply port 132 may be formed so as to be in contact with the water surface to feed the food.

On the other hand, the concentration of the organic matter can be continuously fed back based on the substance measuring sensor 133 to detect the concentration of the food in water in real time. Based on the measured value of the substance measuring sensor 133, The opening and closing of the mouth 132 is automatically controlled to enable stable feeding of food.

In addition, a food filling port 134 is formed, one end of which is exposed to the upper part of the water surface so that food can be filled in the water inlet, and the lid 135 is connected to the upper part of the food filling port 134 can do.

At this time, the food supply port 132 is provided at the lower part thereof with the food storage part 136, so that the food, which is larger than the specific gravity of the water, can be prevented from sinking immediately below the food supply part.

The camera unit 140 and the illumination unit 150 may be provided under the air collecting unit 100 to continuously monitor the environment inside the aquaculture apparatus F or whether there is an abnormality in the apparatus. 150 can selectively emit light of various colors to be emitted, and it is possible to selectively grow a desired color for growth of a fish species by using known light emitting means to create a growth environment.

On the other hand, when the air collecting unit 100 or the mesh unit 200 flows left and right due to the flow of the water, the air layer AL may not be horizontally disposed but may be inclined in an unspecified direction. In this case, the aquarium F may lose its center of gravity in an unspecified direction and may overturn, resulting in the inflow of running water and the inability to secure the air layer AL.

Accordingly, a plurality of horizontal holding weights 220 can be radially coupled to the lower portion of the mesh unit 200 so as to have a constant spacing, so that the balance can be maintained. In spite of a sudden change in direction or speed of the flowing water, It is possible to prevent the phenomenon of overturning the fuse F.

In addition, the mesh unit 200 may be configured to form a frame FR so that the mesh space 210 can be secured with a predetermined shape, and the frame may be bound to a mesh network.

In this case, a stable balance can be maintained by joining the horizontal holding weight 220 radially to the lower portion of the frame FR.

2 to 3, the air generating unit 300 is configured such that the inflow portion 321 formed at one end of the air supply pipe 320 connected to the air pump 310 is exposed to the water surface, The air is supplied to the discharge portion 322 formed in the water.

External air is introduced through the inflow section 321 exposed to the water surface outside the aquaculture apparatus F and discharged through the discharge section 322. This air is collected by the air trapping unit 100 to thereby form an air layer AL ).

The inlet portion 321 and the outlet portion 322 of the air supply pipe 320 are each formed in a U shape so that the end portion of the inlet portion 321 is formed to be directed downwardly and the end portion of the outlet portion 322 As shown in Fig.

This is to prevent the seawater from flowing into the inside of the air supply pipe 320 by the waves of sea water or the like and to induce the air to be effectively discharged.

At this time, the discharge portion 322 of the air supply pipe 320 may include one or more automatic open / close valves 322a, thereby preventing the flow of seawater, while inducing the discharge of air. The automatic on-off valve 322a may be formed using various known valves that are opened to the outside by the pressure of air and can be prevented from being opened to the inside.

The air supply pipe 320 may be formed of a flexible material so as to have a buoyancy portion 323 or to penetrate the buoyancy portion 323 so that the air supply pipe 320 can stably supply air in a state floating on the water surface. have.

As described above, the air pump 310 can generate power by itself by constructing the self-power generation unit 330. In addition, by using external power or a separate battery 336, 300 may be designed to operate.

6 to 7, the self-generating portion 330 includes at least one rotating body 331b on the rotating shaft 331a, and transmits the rotational force of the rotating body 331b And a rotating module 331 is formed to receive the power transmission gear 331c and the rotating body 331b of the rotating module 331 can be moved up and down with the ropes 332 abutted against each other.

At this time, a buoyancy body 333 is provided at one end of the rope 332, and a tension arm 334 having a vertical force different from the buoyancy body 333 is provided at the other end of the rope 332, The rotational force can be transmitted to the generator 335.

Meanwhile, the buoyant body 333 performs up-and-down vertical movement according to the flow of the sea surface, and transmits the vertical motion of the rope 332 as a rotary motion of the rotating body 331b. The buoyant body 333 may be formed in various shapes such as a spherical shape, a flat shape, a columnar shape, an inverted pyramid shape, and a conical shape. The buoyant structure 333 may be formed as a columnar or polygonal columnar portion and a conical or polygonal- .

In addition, the buoyant body 333 may be formed with a fluid inlet and a fluid outlet so as to inject or discharge air, seawater, or the like. Thus, in order to adjust the buoyancy in relation to the tension derivative 334, the buoyancy can be increased by injecting air or by injecting seawater. That is, buoyancy can be adjusted by injecting or discharging air or sea water using the fluid inlet and the outlet.

Furthermore, the buoyant body 333 and the tensioning body 334 may be symmetrically disposed about the rotating shaft 331a, so that the balance of the self-generating portion 330 is secured.

Meanwhile, in the present invention, the normal force applied to the buoyant body 333 and the tension derivative 334 is defined as meaning the resultant force of gravity and buoyancy.

As shown in FIG. 6, the tensioning element 334 may be a gravity body 334a that sinks into the fluid. Specifically, the gravity body 334a applies a predetermined tension to the rope 332 to control the buoyancy body 333 from moving left and right.

At this time, slopes or curved surfaces may be formed on the upper and lower surfaces of the gravity body 334a. When the gravity body 334a moves up and down, it can flow to the right and left due to underwater resistance, thereby reducing resistance by the shape of the gravity body 334a and forming a slope or a curved surface so as to effectively move the gravity body 334a .

In addition, the gravity body 334a is not always provided in water, but may be installed in the water phase in some cases.

Meanwhile, as shown in FIG. 7, the tension derivative 24 may be a second floating body 334b floating on the fluid. Specifically, the buoyant body 333 and the second buoyant body 334b are guided so as to perform an effective vertical movement due to the buoyancy deviation, despite the multi-directional flow of the sea level. Specifically, a constant tension is applied to the rope 332 by the buoyancy difference between the buoyant body 333 and the second buoyant body 334b, and the buoyant body 333 and the second buoyant body 334b are moved in the right- .

At this time, the second buoyant body 334b can also increase buoyancy by injecting air to adjust buoyancy, or reduce buoyancy by injecting seawater. That is, buoyancy can be controlled by injecting or discharging air or seawater by using fluid inlet and fluid outlet.

In addition, when the rotation module 331 is provided in the water, it may be corroded by salt or foreign matter such as marine life may be introduced, so that the self-generating portion 330 may be formed to cover the rotation module 331 .

Meanwhile, the rotating body 331b of the rotating module 331 of the present invention is a pinion gear, and can be moved up and down by being held in contact with a raising gear 332a formed on the rope 332. [

In this case, if the lift 332a can be replaced by a chain and the up and down movement of the rope 332 can be transmitted to the rotation module 331, it can be easily carried out by a person skilled in the art It is to be understood that the invention is not limited thereto.

8 to 9, the rotary shaft 331a is provided with a pair of first and second rotary shafts 331a-1 and 331a-2 arranged side by side, 1 and 331b-1 and 331b-2 may be provided at mutually corresponding positions.

The first and second rotating bodies 331b-1 and 331b-2 of the rotating module 331 are provided with a latch L between the first and second rotating shafts 331a-1 and 331a-2. So that the rotational force of the first and second rotors 331b-1 and 331b-2 can be transmitted to the power transmission gear 331c.

Although not shown in the drawing, a plurality of the rotating bodies 331b and the ropes 332 may be provided, and the respective rotating motions may be changed by independent vertical up and down motions. The latch L may be provided so as to transmit rotational force independently to the latch 331a.

In this case, all the rotational forces of the first and second rotors 331b-1 and 331b-2 are transmitted to the power transmission gear 331c to enable effective power generation. By providing the accumulator 336, Can be implemented.
