Description

Eco-friendly multi-purpose anchor using abalone shell.}

The present invention relates to an eco-friendly multi-purpose anchor using abalone shells that can reduce productivity due to pollution of fish farms concentrated in the Inner Bay area and provide a habitat for aquatic organisms. As existing anchors for abalone and seaweed farming facilities are being indiscriminately dropped into the sea, which has a negative impact on the seabed environment, we provide an eco-friendly multi-purpose anchor that can replace them.

Anchors are often used to secure cage fish farms or fishing gear in a certain location, but anchors are usually expensive and inconvenient to collect after their period of use. Therefore, stones, pebbles, and sand are placed in bales or rope nets for use instead of anchors. A bag made with a back is called a sand bag.

Although the anchoring force on the seabed is lower than that of an anchor of the same weight, the rope is widely used to set up fish farms due to the advantage that there is no problem with the line being wrapped around or entangled in the anchor when using the anchor. Unlike fishing that uses anchors, the reason fish farms mainly use ruffs is due to the fishing method of the fish farms. In general fishing, anchors are used along with buoy lines when harvesting catch, but in the case of fish farms, only the fish cage net is placed on the deck to check the fish, and no fish or anchors are used except for the last fish at the end of the fish farm.

In order to check the catch without lifting the rope, the rope must be long enough to not pull the fish when the fish cage is pulled up to the deck. In fishing grounds where the water depth is usually 10 m, the length of the line can reach 30 m. In this way, if an anchor is used in a fish farm or in a situation where the line that secures fishing gear is long, there is a possibility that problems may occur as the line gets wrapped around the anchor arm or anchor.

On the other hand, bruises have a simple shape, so there is a low probability that the rope will get wrapped around the bruise. The longer the length of the bruise, the more advantageous it is to increase the fixation power of the bruise, so it also has the advantage of being able to compensate for the disadvantages of bruises with relatively weak fixation power. Therefore, in order to reduce the loss of fish farms, it is necessary to reduce the force received by the farms when strong winds and waves occur, but it is also necessary to fundamentally improve the fixation power of the vulnerable ruffs.

Studies related to the fixation power of anchors have been reported, but little research has been done on improving the fixation power of anchors, and even in prior patent literature, domestic registered patent number 10-1731229 and domestic registered patent number 10-1633822 Although the fishing gear device for catching cephalopods is disclosed, the structure of the ruff that functions as an anchor that is still used in the inner bay cage aquaculture industry is made by inserting stones, gravel, sand, etc. into a bag or rope net to secure the cage. It only performed its role.

In the case of the eco-friendly multipurpose anchor of the present invention, by artificially installing a bunker-type eco-friendly multipurpose anchor in the ocean, it not only serves as an anchor for fish, shellfish, and seaweed breeding grounds, but also ultimately enables the proliferation of fish, shellfish, and seaweed in the inner bay, making it possible to use it in aquaculture farms. wanted to increase.

Disclosed is a marine anchor in which the anchor arm is mounted on the fixing piece to be foldable with respect to the hollow fixed structure, and the end of the anchor portion is configured to have its forward movement restricted by the fixing piece.

The purpose of the present invention is to provide an eco-friendly, multi-purpose anchor that can replace the anchor of the existing inner bay fishery that does not reflect the environmental conditions of each sea area or the characteristics of the living organisms of the cage fish farm.

The present invention provides an eco-friendly, multi-purpose anchor for abalone cage farms, which is formed by combining a cubic square plate at the bottom of an upper dome-shaped structure with openings 190 open in four directions.

At the center of the upper dome-shaped structure, an eye bolt extending from the center to the bottom of the vertically downward tetrahedron is fastened to connect the upper dome-shaped structure and the lower aggregate structure. Four dome-shaped rebars are inserted into the upper dome-shaped internal concrete structure, and the inserted rebars Both ends of the aggregate are formed with reinforcing bars protruding outside the upper dome-shaped concrete, and the ends of the insertion portion are bent inward at 90 degrees to provide an eco-friendly multi-purpose anchor for abalone cage fish farms that is welded and connected to the reinforcing aggregate of the lower tetrahedron.

As an embodiment of the present invention, the upper dome-shaped and lower tetrahedral structures provide an eco-friendly multi-purpose anchor for abalone cage farms made of cement mixed with 5% by weight of abalone shell fines in concrete cement.

The lower concrete may be made of a curved shape with irregularities on the bottom surface in contact with the sea floor, and the eye bolts on the outer four-way corners of the lower support extend the tetrahedron vertically to the bottom of the tetrahedron to improve the grip of the lower support, so that the outside of the bottom It can be formed to protrude.

The present invention can not only replace the existing anchor of the Inland Bay fish farm by reflecting the environmental conditions of each sea area or the characteristics of the living organisms, but also maintain the biodiversity of the ground of the Inland Bay fish farm.

Figure 1 is a schematic diagram showing the existing method of fixing a fish farm. Typically, anchors, bags, or sandbags made of stones, pebbles, sand, etc. were used to fix cage fish farms or fishing gear in a certain location. It is necessary to improve the fixation power of existing fixing devices, which are fundamentally weak when strong winds and waves occur.

Figure 2 shows a conceptual diagram in which the eco-friendly multi-purpose anchor of the present invention is installed. The multi-purpose anchor that secures the cage fish farm has a dome-shaped bunker-shaped exterior and a space is formed inside the dome-shaped frame for divers to enter and exit. The present invention is an eco-friendly multi-purpose anchor made by mixing abalone shell and cement. It can serve as a shelter for various organisms by removing organic compounds generated during the growth of fish, shellfish and seaweed inside the upper anchor and the cultivation of inner bay cages.

In addition, the use of an eco-friendly multi-purpose anchor has the advantage of being able to secure ropes to cage fish farms and seaweed farm facilities in the bay from various angles. By forming the structure of the eco-friendly multi-purpose anchor into a dome shape, unlike the existing inner bay type cages that are blocked on all sides and obstruct the flow of sea water, it not only functions as an anchor but also as an artificial reef by allowing sea water to flow, thereby serving as an essential resting place. can do.

Figure 3 shows a 3D model of the eco-friendly multi-purpose anchor of the present invention. The eco-friendly multipurpose anchor of the present invention is made of a semicircular concrete structure with openings in four directions so that the inside and outside can communicate with each other. At the bottom of the semicircular concrete structure, a tetrahedral concrete plate 170 is combined with the upper semicircular concrete structure.

By using the concrete structure of the support as a square frame at the bottom, the area in contact with the sea floor is expanded to maximize friction, and the upper part has a circular (bunker-type) structure to provide a living space for birds and fish and shellfish, allowing fishermen to use abalone cages. , It has the effect of fixing the facilities of a seaweed farm for abalone feeding more firmly than existing bruises or anchors.

In addition, the opening 190, which is open in four directions, is circular so that tidal currents flow in quickly and sediment does not accumulate, creating a clean semicircular interior environmentally, which can provide a comfortable living space for fish and shellfish. Fish and shellfish can move freely through the circular hole, and it is covered with a dome-shaped hemisphere (160), which serves as a hiding place.

Figure 4 shows the substructure of the tetrahedral concrete plate of an eco-friendly multi-purpose anchor. At the bottom of the tetrahedral concrete plate 170, a support pipe is formed to protrude from the upper surface to the lower surface of the concrete plate 170. When a multi-purpose anchor is installed in the bottom, the support pipe can stably support the anchor structure according to the geology by sinking deep into the bottom and being fixed.

Support pipes are formed in four directions inside the upper dome-shaped structure, and the length of the support pipes penetrating downward into the concrete can be formed differently depending on each direction. By forming a bridge-like pipe at the bottom of the concrete plate, the weight of the multi-purpose anchor can be supported. The length of the support pipe can be detached and adjusted depending on the geological structure and state of the geology, and can be adjusted by cutting the length of the leg of the support pipe.

Figure 5 shows a six-sided view of an eco-friendly multi-purpose anchor. Looking at the specific external characteristics and framework structure, the radius of the upper dome-shaped external structure is 280cm, the seawater circulation is open in 4 directions, and the entrance and exit passage for divers is made up of two holes with a radius of 1m each and two holes with a radius of 1.5m. , the height is 50cm and 75cm respectively.

The length of the eyebolt, which extends vertically from the center of the dome to the bottom of the tetrahedron, is 170cm in total and crosses the eco-friendly multi-purpose anchor vertically, of which 20cm is fastened to the lower supporting concrete structure and welded together with the lower reinforced aggregate structure. In addition, the radius of the inner surface of the external dome-shaped structure is 260cm, and the thickness of the dome-shaped concrete is 20cm. The lower concrete structure is a square structure with a width and length of 3m and a height of 1.8m.

The lower concrete may have a curved shape with irregularities on the bottom surface in contact with the sea floor. Since the lower concrete has a curved shape, the contact area requiring friction can be increased.

In the case of eye bolts fixed to the outer four-way corners of the lower support, they are tightened by recessing 17cm into the concrete, and the reinforcing bar thickness is 24mm. However, the eye bolts 180 at the outer four-way corners of the lower support can be formed to extend vertically to the bottom of the tetrahedron and protrude out of the bottom of the tetrahedron in order to improve the grip force of the lower support. From this, the end of the eye bolt protruding from the sea floor can be inserted to increase the fixing force to the sea floor.

Figure 6 shows a design diagram of the arrangement of reinforcing bar aggregate inside the cement of an eco-friendly multi-purpose anchor. Four 30mm radial reinforcing bars are inserted into the upper dome-shaped external structure, and the joints of each reinforcing bar are joined to the joint through welding. In addition, in order to form a reinforced aggregate in a dome with a radius of 270 cm, it has a length of 5 meters, of which 30 cm is protruded to be inserted into the lower supporting concrete structure to connect and support the upper and lower parts.

In addition, the 5m long upper aggregate is formed by protruding outward from the concrete of the upper dome to have a 30cm insertion part, and the end structure of the 30cm insertion part has a structure that is bent inward at 90 degrees.

By being bent at 90 degrees, it serves to firmly connect the upper and lower internal aggregate structures through welding with the internal reinforced aggregate structure of the lower support concrete structure. To fit the outer shape of the upper part, the distance between each rebar aggregate is set at 40cm, and the lower rebar aggregate is also spaced at 40cm so that it can be welded to the upper aggregate. The 40cm margin is welded by joining 39.6cm rebar as reinforcement.

The reinforced aggregate structure located in the center of the lower concrete steel aggregate structure is a framework structure that crosses the entire eco-friendly multi-purpose anchor through welding with eye bolts, which are one of the anchor links coming down from the upper concrete structure. They support me. The tetrahedral concrete support that supports the dome and dome-shaped structures is made of cement mixed with abalone shell fines and has a four-way anchor chain link at the outer edge.

The material for the multi-purpose anchor of the present invention is manufactured using concrete for manufacturing a multi-purpose anchor by mixing 5% by weight of abalone shell fine powder with a mixture of cement sand and gravel. By appropriately mixing 5% of abalone shell fines with cement, the calcium carbonate content can be increased to help shell growth, and the abalone shell fines can play a role in lowering the Ph concentration like that of oyster shells. Figure 7 shows the appearance of an eco-friendly multi-purpose anchor when it is commercialized.

The eco-friendly multi-purpose anchor of the present invention not only creates an environment in which fish, shellfish and seaweed can grow, but also has the effect of replacing the anchor structure, which is one of the existing inner bay cage aquaculture facilities.
