Description

Structure of hemi-spherical a brim fishing grounds

The present invention relates to the structure of caged farms, and more specifically, to provide a space for farming fish and shellfish in normal times, and when various marine pollutants occur, a barrier is easily installed with a small number of people. The present invention relates to a structure of cage cages that blocks marine contaminants from entering the interior.

The cage farm is a farm where fish and shellfish are raised by installing a fence that floats in the coastal sea and netting it. This provided the opportunity for many fishermen to switch from catching to raising fisheries and increased their income.

However, in recent years, the water quality is worsened due to the inflow of wastewater and domestic sewage of the factory, the oil spills due to the oil tanker accident, and the fish and shellfish of the cages have been deadly causing economic damage to fishermen.

In addition, even when a green algae phenomenon occurs in which phytoplankton suddenly increases, dissolved oxygen in sea water increases, but the reproduction of zooplankton increases rapidly, rather, the amount of dissolved oxygen decreases and zooplankton blocks light, causing red tide. do. This causes phytoplankton photosynthesis to cease, and the dissolved oxygen decreases rapidly, resulting in the death of fish and shellfish.

Therefore, although the government is making efforts to establish marine pollution prevention laws for clean seas, most of them are aimed at preventing them, such as spraying ocher soil after the occurrence of pollutants, or by installing barriers around the farms to access pollutants. It was just a basic technique to prevent.

In particular, in the case of the control technology, it takes a long time to control and it is impossible to prevent the flow of pollutants from accessing the cage farm, so it is not expected to be effective in preventing the death of fish and shellfish in the farm. In addition, the installation and dismantling of the enormous size of the barrier around the farm was too much manpower and time, there was a lot of difficulties that was not practical.

In addition, the conventional pollutant blocking device is formed in a form surrounding the entire circumference and the bottom of the fish farm fishing net is required a blocking film of enormous size. Therefore, the conventional pollutant blocking device is impossible to install with a small number of people due to the weight of the barrier film. In addition, there is a disadvantage that it is not easy to tighten the end of the blocking device in the water to block the inflow of contaminants into the end of the blocking device in the water.

In addition, even after the installation of the blocking device there is a problem that it is difficult to secure the active space of fish and shellfish in the farm due to the buckling phenomenon of the blocking film caused by the algae. This resulted in oxygen deficiency in the aquaculture farms closed by barriers, resulting in increased mortality of fish and shellfish.

The hemispherical fishing net 300 and the hemispherical contaminant blocking unit 400 are bent in a hemispherical shape by the rotation of the rotating device 200, so that they can be easily rotated with little force. Therefore, a lot of working personnel are not required, and the work cost is reduced.

The hemispherical fishing net 300, which was coupled to the water by rotation, is changed to be bent upwards, and the hemispherical pollutant blocking part 400, which is coupled to the water surface, is positioned to be bent downward. Therefore, the fish and shellfish that were inhabited in the hemispheric fish net 300 is moved to the hemispherical contaminant blocking unit 400 located in the water and continue to inhabit.

Since the hemispherical contaminant blocking unit 400 is located in the water, even if marine pollutants are generated, the inflow of contaminants is blocked by the barrier membrane 430, and thus, the habitat of the shellfish is not affected. Of course, due to the blocking membrane 430 dissolved oxygen in the interior of the fish farms in case of emergency, such as when there is a risk of death of fish, shellfish separate liquid oxygen supply device 102 is operated to supply oxygen. In addition, by rotating the rotating device according to the state of the sea may change the position of the hemispherical fishing net 300 and the hemispherical pollutant blocking unit 400 may be made to supply fresh seawater.

On the other hand, when the hemispherical pollutant blocking unit 400 is installed in the water due to the generation of marine pollutants, it is also possible to separate and remove the hemispherical fish net 300 rotated to the upper side for convenience of operation. .

The cage farm of the present invention is deformed by the bird or buoyancy and wind pressure by the deformation prevention cross reinforcing rod 370 is installed in the curved center of the hemispherical fishing net 300 and hemispherical pollutant blocking unit 400 is the shape of the cage cage Is prevented.

The cage farm of the present invention is preferably rotated so that the hemispherical pollutant blocking unit 400 is temporarily placed in the water in order to prevent leakage of aquaculture feed to fish and shellfish, as well as during marine pollutants.
