Description

Underwater cage facility {THE UNDERWATER CRAWL FACILITY}

The present invention relates to an underwater cage facility.

The cage facility is installed to raise fish inside, and has been installed in the space within 10m from the sea level.

By the way, when installed in a location close to the sea surface there was a problem such as the destruction of the fish due to red tide, damage to the facility due to strong waves during bad weather such as typhoon.

A technology to solve this problem, it is used to sink to the bottom of the sea without the influence of waves, and it is able to float on the surface to make it easy to move. -0000484).

However, when the cage is injected into the air to maintain the balance, there is a problem that the air pipe line is complicated to supply air evenly to each support.

In addition, the flotation vessel is installed in the lower part of the cage, which may lose its balance if the external shock is greatly affected by the air's tendency to escape from the water into the air.

In order to solve such a problem, the 'cage cultured fishnet structure' was made to adjust the installation position using a rope and to fold or unfold the net with a plurality of buoyancy members 90 in a ring form (Korea Patent Publication) 10-0281366) was also drafted.

The upper cage has been adjusted to the lower position of the cage with a rope and a fixed weight connected to the lower side, and there is no separate facility to restrain the upper cage. there was.

In addition, there is a problem that the net is easily damaged by the weight of the fish because there is no additional support means on the side of the net when the rearing of the fish is raised.

In addition, the anchoring movable spurs and ring meat cages (Korean Patent Application Publication No. 1998-703468) were created, but the upper part of the facility protrudes above the surface of the water, and the facility is easily damaged by strong waves caused by bad weather. There was a problem that it is difficult to balance the formed spur buoy.

Underwater cage facility of the present invention is intended to solve this problem, it is intended to prevent damage caused by waves or red tide by being able to be fixed at a certain position in the water.

In addition, the plurality of horizontal buoyancy member and the vertical buoyancy member is connected to each other in communication with each other has the purpose of maintaining a well-balanced buoyancy structure when the air is supplied or discharged.

In addition, the horizontal buoyancy member and the vertical buoyancy member is formed of a rigid material to protect the net from damage, and also has the purpose of preventing the flow of the net by waves and tides.

When the cage is settled to a predetermined position in the water as installed above, when the air discharge valve 61 of the upper part is opened and then settled, the air inside the buoyancy structure 20 is discharged to the outside through the air discharge valve 61. As the water flows in from the bottom of the buoyancy structure 20, the buoyancy structure 20 is settled.

When the desired depth is reached, the air discharge valve 61 is locked to prevent the internal air from escaping anymore, and then the anchor 80 and the fixing weight 70 are attached to the lower portion of the buoyancy structure 20 so that the buoyancy structure ( 20) do not flow.

In this case, if the sedimentation continues after a certain depth, the air supply valve 51 may be opened and air may be blown from the outside until the buoyancy structure 20 no longer sinks.

When the fish is cultivated and the fish are drawn out, the buoyancy structure 20 can be pulled up by using a crane-mounted vessel. At this time, the air supply valve 51 is opened and the air discharge valve 61 is closed while supplying air. Speed up

Alternatively, the crane may be used only to lift the buoyancy structure 20 using buoyancy in the same manner as above without lifting the crane while ascending to the surface and then move on the surface of the crane mounted vessel.
