Description

[0001] SUBMERSIBLE FISH CAGE APPARATUS [0002]

The present invention relates to an aquaculture apparatus, and more particularly, to a submerged aquaculture apparatus which is formed so that it can be artificially submerged or floated above the water surface in accordance with environmental conditions.

In recent years, interest in aquaculture has been growing in response to the global food crisis, and aquaculture is playing a major role as a major source of aquaculture. For example, aquaculture fish, which account for only 6.5% of world aquatic production in the 1980s Production is now approaching 40%.

In Korea, it is necessary to establish a mass production system for healthy aquaculture products in order to supply stable food of future fisheries and advance into the world market. Recently, the Ministry of Food, Agriculture, Forestry and Fisheries has focused on developing 10 strategic items and plans to achieve $ 10 billion export by 2020, including high-value-added abalone and sea cucumber.

In the case of abalone, the mass production base of abalone was established in the marine cage in the early 2000s. However, productivity has been deteriorating due to mass abuse of abalone due to erosion in the confined marine area recently. In addition, the capacity of abalone farming facilities in Korea has increased from 180,000 in 2006 to 500,000 in 2010, a 180% increase over the past five years. Especially, Wando, which accounts for about 80% of domestic supply, is 53% in 2008 and 30% in 2010.

As the abalone cage facilities are concentrated in such a specific area, the abandonment of the algae and the bottom of the cage have been caused by the deterioration of the fishery environment caused by abalone feces, seaweed and sea tangle residue, 35kg, and aquaculture farmers are increasing their productivity in order to make up for the economic loss caused by our company.

In addition, the abalone cage facilities are mostly located on the surface, and they are very vulnerable to large waves such as typhoons and storms. In 2011, when typhoon "Mui-fa" invasion was caused, damage of abalone cage facilities in western part of Jeonnam, .

Recently, in order to prevent the damage of the abalone cage facilities due to the large waves, it is necessary to protect the abalone cells of 1m X 1m X 0.5m (LXBXD) size with the paints, Although the abalone cage facility is operated in some areas, it needs to be lifted up and down by the ship's crane when feeding or harvesting. It is a labor-intensive facility requiring a lot of power, There is a problem that it is impossible to mass-produce the abalone due to the restriction of the size of the facility.

The buoyancy control unit 300 controls the buoyancy of the frame unit 100 and the cage unit 200 so that the buoyancy control unit 300 can float or float to the sea floor as required. The buoyancy control unit 300 is mounted on the lower surface of the square frame 110 A buoyancy control pipe 310 filled with water or air; a drain pipe 340 connected to the buoyancy control pipe 310 and having a drainage nozzle 341 for draining downward the water during drainage; And two to five submersible pumps 350 installed in the buoyancy regulating pipe 310 for pumping water flowing into the buoyancy regulating pipe 310 and discharging the water to the drainpipe 340, The water flowing out of the pump 350 is moved to the drain pipe 340 via the check valve 351 coupled to the outlet. The check valve 351 is opened only to one side by the water pressure when the pump is operated, and automatically closes when drainage is completed.

The buoyancy control pipe 310 has a filling space 311 in which air or water can be filled therein. When the buoyancy control pipe 310 is filled with air, The entire aquaculture device (1) floats toward the surface of the water and sinks below the surface when the water is filled. When the buoyancy regulating pipe 310 is filled with air, the squeegee frame 110 and the rim of the buoyancy regulating pipe 310 can be adjusted in accordance with the amount of water filled in the buoyancy regulating pipe 310. [ The submerged aquaculture apparatus 1 can be raised to such an extent that the unit 200 can be exposed above the water surface, so that feeding and maintenance can be performed. When the buoyancy control pipe 310 is filled with water, .

4, a water level meter 136 is installed inside the buoyancy control pipe 310. An open / close valve 135, which is electrically operated, is installed at an upper portion of the plurality of water inlets 134 through which water is introduced And the water level meter 136 and the on-off valve 135 are interlocked with each other to automatically or manually control the flow of water to be filled in the buoyancy control pipe 310.

The level indicator 136 may drain the buoyancy regulating pipe 310 to float the submerged aquaculture apparatus 1 to stop the operation of the underwater pump when it reaches a low level, 310 may be filled with water at a high level, the opening / closing valve 135 may be closed to prevent further inflow of water.

The frame unit 100 is provided with a frame fixing part to prevent the frame unit 100 and the frame unit 200 from being floated when the buoyancy adjusting pipe 310 is filled with air and the frame unit 100 is lifted. The frame fixing part 150 includes a weight 151 and a connection cord 152 for connecting the weight 151 and the rectangular frame 110. [

In addition, the buoyancy control pipe 310 is connected to an air power hose 320 through which air is introduced or discharged, and the air power hose 320 is connected to the buoyant body 330 floating on the water surface, And serves as a passage through which the air that is introduced into or discharged from the pipe 310 moves. Preferably, the air power hose 320 is formed to have a sufficient length so that the end portion may be exposed above the water surface even when the submerged aquaculture apparatus 1 sinks on the sea floor.

A power supply cable for supplying power for driving the underwater pump 350 and the on-off valves 135 is extended to the inside or the outside of the air power hose 320 and the power cable is connected to the inside of the buoyancy body 330 And the power source may be supplied from a fishing boat to drive an underwater pump 350 installed in the buoyancy control unit.

The drain pipe 340 is connected to the buoyancy regulating pipe 310 through a submergible pump 350 for discharging the water filled in the buoyancy regulating pipe 310 to the outside, (Not shown).

When the buoyancy regulating unit 300 discharges the water inside the buoyancy regulating pipe 310 to improve the buoyancy when the submerged aquaculture apparatus 1 is lifted upward, air flows through the air power hose 320 And is filled in the buoyancy regulating pipe 310 to form buoyancy.

The drainage nozzle 341 formed in the drainage pipe 340 is formed so that the direction of the nozzle is downward so that water can be discharged downward. Therefore, when water is drained, a reaction force for discharging water can be obtained, The aquaculture device (1), while sitting on the seabed, strongly discharges the water downward, and can serve to clean the food residue accumulated in the sea floor or the animal waste.

The submerged aquaculture apparatus 1 according to the present invention described above can submerged the cage unit 200, which grows cultured fish according to external environmental conditions such as a typhoon or a wave, Can be stabilized and managed smoothly. As the aquaculture environment improves, the production rate of the aquaculture fish can be lowered due to the lowered mortality rate.
