Description

DEDECOR FOR RED TIDE CUT OFF OF FISH FARM}

The present invention relates to an enemy even device that prevents red tide from penetrating into a cage farm where fish are hung by floating a net in a float, and more specifically, a membrane through which pores of micropores through which only seawater passes. The present invention relates to a device for preventing red tide from being trapped around the net of caged fish farms so that the damage caused by red tide can be prevented in advance.

In general, aquaculture is being actively carried out in the coastal seas using cage farms where fish are hung in the nets to fish.

This cage farm is designed to easily raise a large amount of fish in one place by preventing the fish from escaping from the outside by a net suspended from the float, and the structure of the cage is suspended along the circumference of the net and the net. Phosphorus furnace (作業 路) is installed.

These cages are used to produce large amounts of fish in a small amount of space, which contributes to the income increase of fishing villages, or material damages are frequently caused by dead fish in cages caused by red tide occurring in coastal seas. .

Red tide is caused by coastal eutrophication due to environmental pollution. When such red tide occurs, mucus substances secreted by phytoplankton increase the viscosity of seawater, making it difficult for fish to swim. The gills of these fish can be blocked to suffocate the fish and paralyze nerves, causing large amounts of fish to die.

In addition, when phytoplankton dies and is decomposed by microorganisms, oxygen dissolved in seawater is consumed, resulting in a lack of dissolved oxygen, which causes fish to die from breathing problems. As such, red tide causes deadly consequences for marine and freshwater organisms, and efforts are being made to prevent red tide worldwide. For example, when red tide occurs, the red tide is loaded with loess on a large ship and sprayed over the surface of the sea to immerse it. Red tide has been removed by the method.

However, the method of spraying ocher on the surface of the sea, that is, sea level, has a problem in that it cannot prevent red tide occurring in a large area at once and requires a lot of manpower.

On the other hand, the devised to prevent the damage of the cage farm due to the red tide has been devised.

As an example, the 'Utility Model No. 381210', 'Crown Farm Red Tide Preventing Device', has been devised, which is indicated by the claims of the registered publication, and is a float floating on the sea surface and below the sea level hanging on the float. A cage farm red tide prevention device for preventing red tide by spraying bubbles into the water below sea level in cage cages formed by arranging several caged cages including sagging nets, wherein the cage cage is located on one side of the cage cage A pump installed at a barge for compressing and supplying air, a pipe having one end connected to the compressed air supply side of the pump and extending to each of the caged shells, and one end connected to the pipe, and the other end being connected to the pipe An injection pipe immersed below the inner sea level of each cell, and the other end of the injection pipe Is connected is configured to supply the air to the bubbling nozzle for spraying the water to bubble state.

Therefore, by injecting bubbles into the cage shell of the cage farm to circulate the water in the cage and to increase the amount of dissolved oxygen to have the advantage of preventing red tide.

As another example, registered utility model No. 311222, `` Aquaculture Redevelopment Prevention Device, '' was devised, which, as described in the claims of the publication, was buried in the sea surface by buoys fixedly attached to the top border. A fixed frame which is installed to form an opening and forms a frame, a fixed net which is fixed to cover the slope and the bottom of the fixed frame, and a plurality of cage nets for trapping fish, and a plurality of cage nets installed on the bottom of the cage net so that the cage net is vertical In constructing a removal device for removing the red tide generated in the cage farm consisting of a weight, the ship is fixed to the sea surface to supply air to the inside of the cage, or the power source and the ship engine to the presidential ship It is fixedly connected to the crankshaft that rotates by receiving the driving force so that it can elastically close to the inner circumferential surface of the inner housing. Both ends of the inlet is equipped with a graphite adhesive to the left and right reciprocating rotor, and the inner circumferential surface of the inner housing inlet provided to suck the air corresponding to the left and right reciprocating movement of the rotor facing each other And inlet and exhaust valve plates provided on the outer circumferential surface of the inlet and the outer housing so as to be open and close to correspond to the left and right reciprocating motions of the rotor, and the air corresponding to the opening and closing of the exhaust valve plate. A reciprocating vane pump having an outer housing having one outlet for air discharge is wrapped around the inner housing to form a discharge space, and one end is fixedly connected to the reciprocating vane pump to discharge air. A supply pipe for supplying the bottom surface of the cage to the bottom, and the other end of the supply pipe is fixedly fixed to the outer circumferential surface so as to communicate with the inside However, the inner circumferential surface is composed of an air stirring member formed of a hollow cylindrical body so as to spirally spray seawater together with the air supplied through the supply pipe.

Therefore, the air supplied through the supply pipe to the other end of the supply pipe connected to the reciprocating vane pump is discharged in an oblique direction to the inner circumferential surface of the body and at the same time, clean seawater is introduced and stirred along the guide vane. By discharging farther, it is possible to push out the red tide creatures formed on the sea surface out of the cage and increase the dissolved oxygen by supplying more fine air into the cage, thereby preventing the death of fish.

However, the above-described anti-red tide devices of cage cages are not only burdened by the cost of installing the components, but are also exposed to seawater at the place where they are installed. There is a problem that the elements are rusted or corroded.

In addition, only the means for raising bubbles in the cage farm or inflowing clean seawater to increase dissolved oxygen in the farm can not prevent red tide from coastal seas from penetrating into the cage. Even if to increase the problem of having to proceed separately to the yellow soil to remove the red tide is penetrated.

The present invention has been devised to solve the problems of the conventional red tide prevention device of caged farms, and has a barrier film with less micropores on the mesh circumference of caged farms to prevent infiltration of materials with a specific gravity greater than the volumetric weight of seawater. Even if red tide occurs in the coastal seas, the red tide penetrates the inside of the cage to prevent the fish from being killed by the red tide. have.

In order to achieve the above object, the antagonist cutout device of the cage farm, which is the present invention, in a cage farm having a net that is accommodated and fished therein, and a work path partitioned along the circumferential surface of the net and floating on the sea surface A fixed body formed of a float that is captured along the circumference of the working furnace and floated on the sea surface; A blocking film having an upper end fastened to the fixed body and having a small fine hole through which seawater passes, and at least one cutout having one side cut off on a surface thereof; It is characterized in that the weight is added to the cutting portion of the blocking film to prevent the blocking film from rising from the sea surface.

The blocking membrane may be fastened by winding an upper end of the fixing portion to the tole portion.

The lower side of the barrier membrane may be further configured to prevent the barrier membrane from flowing to the left or right in accordance with the flow of sea water.

In addition, the upper end is fixed to one side of the fixing body to capture the circumference of the work path and the lower end side may further include a flow preventing member having a connecting line connected to the fixing rod is fixed to the sea surface of the sea.

In addition, the blocking film may be configured to be foldable by a plurality of rings that are inserted into the outer periphery of the fixture.

Even if the red tide is generated by the barrier that passes only the seawater, which is seawater, the red tide is penetrated into the net installed in the cage, thereby preventing the red tide from penetrating into the net. It is possible to prevent the death of fish caught and farmed, and not only to reduce the economic loss caused by red tide, but also by the simple configuration, it does not greatly burden the installation cost, and it does not interfere with the seawater even if it is installed for a long time. It does not rust or corrode by being made of a non-hazardous material.
