{Device for raising Shellfish}

The present invention relates to a shelter for abalone cultivation, and more particularly, to a shelter for abal tissue cultivation, in which at least one of a T pipe structure and a transverse plate plate is coupled or connected to an upper portion of a vertical plate, The present invention relates to a shelter for abalone cultivation having a T-shaped bend.

Shells are shells of animals belonging to molluscs, and they are composed of single shells, multi - shell shells, bamboo shells, ) And a small part of the most part of the southern part of the reservoir and part of the Huzhou sub-arc, the gut river, the tribal river, and the bamboo river.

Gastropods belonging to shellfish refer to animals belonging to the crawling body of mollusk animals. In the case of dissolution, useful marine resources such as seashells, abalones, and buckets, and various marine shellfish belonging to the sea breams, and sea- Belongs.

Most of the shellfish are attached horizontally between rocks and rocks and distributed throughout the sea area. The distribution of abalone, which is a marine gastropod, is widely distributed from one sea area to the tropical sea area. So, in addition to the sea turtles, It occupies an important position.

In recent years, the number of spawning grounds and habitats such as environmental pollution and coastal landfill in coastal fisheries have been gradually decreasing. Since the production of artificial seeds has been carried out as demand has increased, the area of cultivation has been increasing year by year.

The method of breeding generally consists of using the flooring method used in the cattail culture and discharging the cattles and harvesting after growth, in the form of land tanker style and marine cage style, have. Sea caged aquaculture is a method of putting objects in a container made of a net and hanging it in the middle or lower layers of seawater. As the aquaculture is affected by the weather and the season, and the marine pollution is deepened,

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to a specific configuration and an attached drawing relating to a rolled ablator having a T-shaped bend.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 shows a wafers frame of an overturning shelter having a T-shaped bend of the present invention. Most shellfish organisms are benthic living on rocks and walls, and most of them are nocturnal and can be stressed by light irradiation, so it is appropriate to create an environment in which aquatic organisms can adapt as much as possible.

The shelter of the present invention comprises a plurality of wafers (21) which are fixedly coupled to a connecting pipe and a binding opening at regular intervals. The wavy plate frame has a "T" shaped structure when viewed from the left and rear directions, with a transverse plate plate connected to the top of the vertical plate plate.

The vertical plate plate is symmetrically formed with a wedge connection hole 24 so that at least one wedge frame can be fixed by passing through the wedge connection pipe and the wedge fixing hole 23 is additionally formed, The wave plate frame can be fixed.

At the edge of the upper surface of the transverse plate plate, a food jaw having a predetermined height is formed at a predetermined interval, and the food jaw prevents the food fed from the upper part from flowing down and being lost downward. The structure of the present invention which can prevent the loss of food like this can avoid the phenomenon of aquaculture in the aquaculture tank, thereby enhancing the productivity of the aquaculture farm.

For example, when food is fed, if the food is not evenly distributed in the aquarium, and it is driven to one side, the aquaculture is also driven to one side to feed the food. In such a case, the environment in the aquaculture tank may be partially changed, which may worsen the aquaculture environment of the area where the individual is caught in the aquarium. In addition, individuals with easy access to food are more likely to grow, so even if they are raised in the same aquaculture, they will show differences in growth rates, which will inevitably lead to a decline in productivity compared to farms with uniform growth rates.

The wiped frame may be formed by installing at least one wiped frame unit having different height of the vertical plate plate at an intersection. That is, it has an installation structure in which a wavy plate frame having different height is repeatedly formed, thereby increasing the area of attachment, and at the same time, when the food located on the upper side of the side plate is moved by the flow of the water flow, It is possible to prevent the food from being directly lost to the bottom of the tank.

In addition, in the blower installed on the bottom of the water tank, the solar shielding effect inside the shelter is high, and in the oxygen spraying, a horizontal plate coupled with a small vertical plate is firstly dispersed, As the plate is dispersed from the lower part of the plate wing and moved to the upper water surface, the time for staying in water is increased, so that the number of breeding water is sprayed in all directions, and the remaining time is increased and dissolved oxygen amount can be increased. In the case of the aquaculture tank in which the attached biological aquaculture device is in contact with the breeding aquarium and the blower is installed at the lower part, more space is provided for jetting air to the lower portion of the aquarium than the conventional shelter, thereby improving the gas- , It is possible to further facilitate up-and-down circulation of the breeding water. In addition, it is advantageous in that the sprayed water can be cleaned by using the falling water while being flowed from the upper plate plate having a higher height to the lower plate plate having a lower height, even when the water is simply sprayed even in a cleaning operation.

The horizontal and vertical plates of the present invention can be manufactured through injection molding using an arm frame frame and a male frame frame. Injection molding refers to a method of molding a material (injection material) by pushing it in. Generally, thermoplastic plastic raw material is put into a hopper and melted by heat. After appropriate pressure is applied, the material is pushed into a mold . The arm frame frame is a frame having a structure similar to the aquarium frame of the present invention and can be fixed by overlapping several frames with the grooves of the arm frame. On the side of each frame frame, an injection hole is formed to inject injection material from the outside, and the injection material is injected into the frame frame by fusing the injection material at high temperature and high pressure.

The injection material injected in the molding process of the present invention is one of engineering plastics such as polyamide, polyacetal, polycarbonate, polyphenylene oxide, polybutylene terephthalate, high density polyethylene, vinyl chloride hard resin , And the injected molten material is hardened and separated from the mold.

Fig. 2 shows a shelter for abalone cultivation with T-shaped bending of the present invention. In case of being used on the land, one or more wiping frame units having different height of the vertical plate plate may be installed at one intersection, and the wiping frame may be fixed by passing the wedge connecting hole through the wiping connecting pipe 24c.

When the shelter is installed on the sea, the shelter is easily separated and broken by the above fixing by the wave. In order to prevent this, the horizontal fixing hole formed in the vertical plate is inserted through the horizontal fixing pipe 26a and the vertical fixing pipe and is fixed by the coupling hole 26b to increase the binding force between the wave plate frames and the fixing force of the shelter .

A plurality of wave plate connection holes formed in the vertical plate may be formed in the vertical direction. It is possible to adjust the height of the vertical plate by binding a binding hole at a certain height of the wave plate connection hole. In other words, since the depth of reach of light can be deepened in a marine aquaculture farm at a high altitude of the sun, the depth of the light transmitted through the water can be controlled by the combination with the transverse plate by adjusting the height of the vertical plate.

Since most of the adhered aquaculture is nocturnal, it cuts off the light by T-shaped bend to reduce darkness of the individual and reduces the stress to the aquaculture by giving stability to the aquaculture. Thus, it is possible to improve the productivity by smoothly controlling the intensity of the inside space of the farm in accordance with the habits of the aquaculture such as abalone, which takes a rest during the day and feeds at night.

FIG. 3 is a plan view, a front view, and a side view of the overturning shelter having a T-shaped bend according to the present invention, and a cross-sectional view is shown on the lower side. When the wiping frame having different height is installed at an intersection, the interval is set such that the width of the wiping plate unit of the wiping frame unit having a relatively high height of the vertical plate is relatively small, Be separated.

This is to reduce the stress of aquaculture by efficiently blocking the wide angle of light and attaching to the wave plate. At this time, when the wiping frame units having different height are arranged alternately, the wiping interval can be adjusted by mounting the wiping pipe 24c differently, and the wiping frame number can be adjusted by the wiping pipe. The pipe connection pipe is a hollow structure such as a pipe, and both side openings can be formed as a fixed portion and a receiving portion, respectively. The outer surface of the fixing portion is formed with a fixing device such as a screw thread, and the fixing portion is formed to have a proper diameter so as to pass through the wedge connecting hole and to correspond to the inside of the receiving portion of the other winged connecting pipe.

The plan view of the apparatus for adhering biological organisms according to the present invention shows a stone publication 112. When the adhering biological aquaculture apparatus according to the present invention is put on the aquaculture tank, the edge of the aquaculture apparatus can come into contact with the wall of the aquaculture tank due to the flow of the aquaculture water or the bubbling. At this time, there is a possibility that the young aquatic organisms may be drowned in the aquaculture apparatus and the aquaculture tank, or the shell may be broken. In order to prevent this, a water tank separating stone plate 112 is formed in the middle of the front and rear parts of the attached biological aquaculture apparatus. Even if the aquaculture apparatus touches the water tank wall, a space is formed by the protruded portion of the stone plate 112, It is possible to prevent damage to the aquatic organisms such as water.

As shown in FIG. 3, each of the wave plate connecting pipes can be connected continuously to control the number of the wave plate frames. After the inner pipe 24b is received therein, the connecting pipe is sealed by the fixing stopper 24a It is possible to prevent each of the wiping frame units from being separated.

Fig. 4 shows a style frame in which a shelter for abalone cultivation having the T-shaped bending of the present invention is housed. The overturning-type shelter 20 having the T-shaped curvature of the present invention may be installed at one or more inside the culture frame in which the upper part is open and the inner space is formed. Conventional shelters are often composed of slate-type wafers, and in many cases, food is poured into a portion where the bones are broken at the time of feeding, which makes it difficult to evenly distribute the wastes throughout the aquaculture tank.

However, the adhering biosynthetic apparatus disclosed in the present invention is advantageous in controlling the density of an individual, since the food is seated on the side plate and fed to the side plate when the food is fed, thereby facilitating distribution. In addition, since the food jaws are formed on the upper edge of the side wing, the food placed on the upper side of the side plate is prevented from flowing to the floor, and the food utilization rate can be increased because it stays in a position where access to the aquaculture is easy. The feed jaws are formed with projections each having a predetermined length at a predetermined interval on the edge of the upper surface of each of the lateral plates.

Removing from the Aquaculture tank as soon as possible is a major factor in aggravating the aquaculture environment of the aquaculture animal that is immersed on the bottom of the aquaculture and the food remaining after ingestion. When the conventional shelter is used, the area where the shelter touches the aquaculture tank is large or the bottom of the shelter has a certain angle and the foreign material is deposited between the shelter and the aquaculture tank bottom while contacting with the bottom of the aquaculture tank. Especially, in the case of culturing aquaculture, it is difficult to completely remove foreign matter by circulation of water, or by water spraying, and it became a factor of deterioration of quality of breeding in the long term. However, the adhered biological aquaculture apparatus disclosed in the present invention is perpendicular to the breeding tank and is in contact with the breeding tank, and has a small contact area, thereby facilitating effective removal of foreign matter.

Fig. 5 shows a form frame in which a shelter for abalone cultivation with a T-shaped bend of the present invention is accommodated. The culture frame 10 of the present invention may be formed by forming an outer wall around the bottom frame and the bottom frame, and is suitably made of a material such as linear low density polyethylene (LLDPE), which is excellent in heat sealing, flexibility, and price.

The bottom frame of the aquaculture frame is constructed with a water trap. At both sides of the aquaculture frame, a stepped structure such as an inverted letter "A" is formed. The central portion of the bottom frame is formed with concavo-convex structures in which the inclined planes are symmetrically connected to each other so that the projections and the concave portions alternately form a plurality of lines. The protrusions constituting the concavo-convex structure have a structure in which the width is narrowed as the width is increased to the top, and a plurality of the protrusions are formed at least at regular intervals so that the cross-section can have a trapezoidal shape or a pyramidal shape.

A blower (11) can be installed on the protruding portion of the concavo-convex structure. When the shelter is housed in the culture enclosure, the space between the protrusion and the space where the shelter is installed is shortened, so that the blower effect can be enhanced.

In shellfish farming, it is possible to produce high quality aquaculture by preventing water from accumulating in the breeding tanks and accumulating the circulation of the breeding water and the debris. Accordingly, at least one drainage port 14 is formed on the lower side wall of the edge surface of the culture enclosure in which the water receptacle is formed. Generally, when a plurality of culture platforms are installed in one long-life tank, it is appropriate that the drainage port is installed on each of the symmetrical side walls so that the breeding water can be drained in one direction.

One or more shelter for abalone cultivation having the T-shaped bending according to the present invention may be installed in the cultivation shelf, and may be installed at a protruding portion of the culture shelf, and may be installed at a certain distance from the floor. Therefore, it is possible to facilitate the removal of waste products and feed debris from aquatic organisms through the water receptacle structure of the bottom frame and the frame formed by the projections and recesses.

The waste materials, feed waste and the like of the aquaculture living in the shelter of the present invention are automatically slid toward the concave part along the inclined surface formed by the concave-convex structure of the bottom part of the culture mold. Since the water stream formed in the breeding tanks moves only in one direction along the frame portion and the recess formed by the water receiving portion, the force is not dispersed in various directions and the drainage speed is accelerated.

Particularly, the water-receptacle frame portion is formed with a high flow velocity to facilitate removal of feed residue at the corner of the culture chamber, and the shelter of the present invention is spaced apart from the bottom portion of the culture frame, Can be prevented. According to the presence or absence of the through-holes 13 formed in the outer wall, the culture pan can be divided into the first and second embodiments so as to be independently installed in a space other than the long-lived water tank or the long water tank.

Fig. 6 shows Embodiment 1 of the style frame of the abrading-type shelter having T-shaped bending according to the present invention. The form frame of the present invention is formed in a size that can be accommodated in a long life tank and can be installed at least one in a long water tank. At this time, in order to circulate the water inside and outside the aquarium, A through hole 13 is formed.

Since more than one style frame is installed in the long-term pool, it is possible to classify according to the breeding season and species according to the type of floodplain, and the floodplain and feedstuff can be cultivated at the high flow rate. It is pushed to the vicinity of the drainage hole by the water flow and is distributed unevenly in the water tank, so that the feeding efficiency of the spore is lowered and the growth of the aquaculture can be prevented from becoming unbalanced.

Fig. 7 shows Embodiment 2 of a styling form of a shelter for abalone cultivation having T-shaped bending according to the present invention. The aquaculture mold in which the abacus aquaculture shelter having T-shaped bending according to the present invention is accommodated may be separately provided in a space outside the longevity tank, so that the aquaculture itself can serve as a culture tank.

7, the size of the outer bottom, inner bottom, and side portions are not rectangular but rectangular, so that the size of each of the sizes can be increased. The sanitary napkin has an opening in the upper direction and a square having a predetermined height and a length in the front, rear, left and right directions. The side wall is formed with a cradle portion having a height of a predetermined distance in the longitudinal direction and protruding in an inner shape of the water tank, A concavo-convex portion for reinforcing the side wall is formed. The trapezoidal concavo-convex portion and the triangular concavo-convex portion, which are flat on the upper surface, are provided in the longitudinal direction. In the case of the conventional rectangular shape, there is a phenomenon that the attachment creature tilts to one side of the water tank, I was able to breed separately. Therefore, no hole is formed in the outer wall of the culture frame, and the culture density can be increased by providing one or more culture frames with a multi-layer structure as shown in FIG.

As shown in FIG. 7, when the attached organisms are separated into the square water tank, the growth environment can be created for each water tank, and the feeding rate according to the growing condition can be controlled differently. The phenomenon of aquaculture in aquaculture is related to the productivity of aquaculture. For example, when food is fed, if the food is not distributed evenly in the aquarium and is driven to one side by water movement, the aquaculture also moves to one side. In this case, the environment in the aquaculture tank may be partially changed, which may deteriorate the aquaculture environment of the area where the individual is caught in the aquaculture tank. In other words, in the case of feeding water in the feeding period, as the food flows in the direction of drainage according to the water flow of the feeding water, the adherent organisms are concentrated and the density of a part of the food is increased. The more easily access to food, the more favorable the growth will be, and even the individuals growing in the same aquarium will show a difference in growth rate, and the productivity will be lower than that of all the farms with uniform growth rate.

However, when the aquaculture tank is small, as shown in FIG. 7, it is possible to uniformize the environment by using a laminating method of the separated volume, increase the individual density according to the increased attachment area, have.
