Description

Technology Field

[0001] The present invention relates to a buoy assembly for seaweed farming, and more specifically, by connecting a pair of left and right buoyancy bodies with a connecting rod to support a seaweed net, an inner connecting rod formed in the shape of a long ladder and an outer connecting rod formed in the shape of a short ladder are inserted into a coupling groove formed in the buoyancy body and are integrally coupled by a turn-buckle type connecting socket, thereby enabling quick and easy assembly between the inner and outer connecting rods and the buoyancy body while maintaining a rigid coupling state between the buoyancy body and the connecting rod. Background Technology

[0003] Generally, laver is a type of seaweed that grows in the upper layer of the intertidal zone, which is submerged during high tide and exposed during low tide. Fishermen who cultivate laver using a floating method turn over the laver nets connected to the floats so that they are exposed to sunlight on the water surface twice a day.

[0004] For seaweed farming, floats that float on the water surface, connecting rods installed between the floats to maintain a constant distance between them, and seaweed nets installed on the floats or connecting rods must be provided. However, conventional floats are made of styrofoam, which, although they can easily maintain a floating state on the water surface, cause serious environmental pollution due to the problem of them easily breaking or crumbling upon external impact, and the marine ecosystem is currently under threat due to the death of fish that swallow the crumbled styrofoam pellets.

[0005] In addition, conventional connecting rods for seaweed farming buoy assemblies have used only bamboo to ensure they are lightweight and do not break easily. However, to extend the lifespan of bamboo that is exposed to sunlight and submerged in seawater, rods with a resin sheet covering the outer surface of the bamboo are being used. Nevertheless, since the bamboo must be replaced whenever it rots and fails to perform its function, there was a problem in that a large amount of money was spent on maintenance, including the purchase and reinstallation of the connecting rods.

[0006] In addition to this, in order to install bamboo connecting rods on the buoys or to secure the seaweed nets to the connecting rods or buoys, ropes must be used to tie them together so that they are connected. This inevitably increases working time, and since a large workforce must be employed to reduce working time even if it increases labor costs, the series of processes for seaweed farming acts as an economic burden for seaweed farmers.

[0007] Recently, in order to improve these problems, the lifespan of the product has been extended by manufacturing the float and connecting member with synthetic resin as disclosed in Patent Documents 1 to 4, and research is continuously being conducted to make the float and connecting member easier and more convenient to combine.

[0008] However, conventional connecting rods made of synthetic resin for seaweed farming floats had the problem of easily bending or breaking. Furthermore, producing the connecting rods by an extrusion method caused a decrease in strength, and the connection between the connecting rod and the float was incomplete. Additionally, the connection process was complicated and difficult, and problems such as the connection between the connecting rod and the float loosening due to repeated shaking on the water surface also occurred.

[0009] Meanwhile, in order to solve such problems, the applicant developed a buoy assembly for seaweed farming according to Patent Document 5. Patent Document 5 had a structure in which a connecting member for connecting a pair of left and right buoyancy bodies was composed of multiple unit pipes, and these multiple unit pipes were connected in sequence by connecting sockets, and the ends of the unit pipes constituting the connecting member were fixed with a fixing socket while inserted into the insertion opening of the buoyancy body. However, problems were raised that the assembly process required a considerable amount of time due to the excessive number of unit pipes constituting the connecting member and connecting sockets, and there was no guarantee that the structural strength of the connecting part could be maintained for a long time, leading to the development of the present invention.

[0012] The present invention has been devised to solve the aforementioned problems, and the objective of the present invention is to provide a buoy assembly for seaweed farming with an improved structure that allows for quick and easy joining of a pair of left and right buoyancy bodies and a connecting rod, as well as improving the structural joining strength of the connecting part. means of solving the problem

[0014] To achieve the above objective, the present invention provides a buoy assembly for seaweed cultivation comprising a pair of left and right buoyancy bodies and a connecting member connecting the left and right buoyancy bodies, wherein the buoyancy bodies are provided with an inwardly concave coupling groove on the outer side of the left and right sides, and a through hole through which the connecting member passes is formed on the inner side of the coupling groove, and the connecting member is composed of an inner connecting member formed in a ladder shape by integrally forming a pipe-shaped vertical member between two parallel pipe-shaped horizontal members, and an outer connecting member formed in a ladder shape shorter than the inner connecting member, and the ends of the inner and outer connecting members are inserted into the coupling groove formed on the outer side of the left and right sides of the buoyancy bodies and are integrally connected by a connecting socket.

[0016] In a preferred embodiment, a male screw portion is formed at the end of the horizontal member of the inner and outer connecting member to be screwed into a connecting socket, and a female screw portion is formed in the connecting socket to be screwed into the male screw portion of the inner and outer connecting member in a left-right symmetrical state such as the body of the turn-buckle, so that the inner and outer connecting members can be connected in a straight line by rotating the connecting socket in one direction, thereby allowing the assembly work to be done quickly and easily. Effects of the invention

[0018] According to the above-described embodiment of the present invention, a pair of left and right buoyancy bodies and inner and outer connecting members can be quickly and easily combined as a single unit using a connecting socket formed in the shape of a turn-buckle body, thereby facilitating the assembly process. Although the method of combining them is simple, the vertical members of the inner and outer connecting members are inserted into the connecting grooves on both sides of the buoyancy bodies, and the ends of the horizontal members pass through the through holes. Since they are pulled together and tightened by the connecting socket to form a tightly combined unit, the combined structure is robust, so there are advantages such as the fact that they do not easily come loose or break even when subjected to external forces such as the influence of waves or the turning of the seaweed while installed on the water surface.

[0021] Hereinafter, preferred embodiments of the present invention that do not limit the invention will be described in detail with reference to the attached drawings.

[0022] FIGS. 1 to 4 illustrate a buoy assembly for seaweed cultivation according to the present invention, comprising a buoy assembly (1) for seaweed cultivation composed of a pair of left and right buoyancy bodies (100) and a connecting member (200) connecting the left and right buoyancy bodies (100);

[0023] The above buoyancy body (100) is provided with an inwardly concave coupling groove (110) on the outer side of the left and right sides, and a through hole (120) through which a connecting member (200) passes is formed on the inner side of the coupling groove (110);

[0024] The above connecting member (200) is composed of an inner connecting member (200a) formed in a ladder shape by integrally forming a pipe-shaped vertical member (220) between two parallel pipe-shaped horizontal members (210), and an outer connecting member (200b) formed in a ladder shape shorter than the inner connecting member (200a);

[0025] The ends of the inner and outer connecting rods (200a, 200b) are inserted into the connecting grooves (110) formed on the outer sides of the left and right sides of the buoyancy body (100) and are connected integrally by the connecting socket (300).

[0027] In this embodiment, a male screw portion (212) that is screw-coupled to a connecting socket (300) is formed at the end of the horizontal member (210) of the inner and outer connecting members (200a, 200b), and a female screw portion (310, 320) that is screw-coupled to the male screw portion (212) of the inner and outer connecting members (200a, 200b) is formed in a left-right symmetrical manner, such as in the barrel of a turn-buckle, that is, a left-handed female screw portion is formed on one side and a right-handed female screw portion is formed on the other side, so that the inner and outer connecting members (200a, 200b) can be connected in a straight line by pulling and tightening them together by rotating the connecting socket (300) in one direction using a hand or other tightening tool.

[0029] In this embodiment, the connection method between the inner and outer connecting rods (200a, 200b) and the connecting socket (300) is illustrated and described as a screw connection method; however, the present invention is not limited to the screw connection method described above, and it is obvious that various connection methods may be applied, such as the connection method between a locking pin and a locking groove, which is the connection method of scaffolding pipes for construction.

[0031] In this embodiment, the pair of buoyancy bodies (100) are each formed by injection molding into divided bodies that are symmetrically divided on the left and right sides, and a space for forming buoyancy is formed inside. On the butting surfaces of the divided bodies, flange portions are formed on the outer side so that they become one by mutual fusion. On the outer side of each divided body, a coupling groove (110) as described above is formed so as to face each other, so that the vertical member (220) portion of the inner and outer connecting members (200a, 200b) can be fitted into each other. On the inner surface of the coupling groove (110), two through holes (120) are formed in the left and right directions so that the horizontal member (210) portion of the inner and outer connecting members (200a, 200b) can pass through.

[0032] Accordingly, a connecting socket (300) is positioned in the space between the connecting grooves (110) spaced apart on the outer left and right sides of the buoyancy body (100), so that the inner and outer connecting rods (200a, 200b) can be assembled together as one.

[0034] In addition, in this embodiment, the buoyancy body (100) is generally cylindrical, but the upper side, that is, the connecting groove (110) side where the connecting rod (200) is connected, is generally horizontal, thereby improving the support strength of the connecting groove (110) and allowing the buoyancy body (100) to be inverted so that the seaweed attached to the connecting rod (200) can be stably maintained in a state where it is floating on the water surface and a state where it is submerged below the water surface.

[0036] In this embodiment, the inner connecting member (200a) has male screw portions (212) formed at both ends of the horizontal member (210), and the outer connecting member (200b) has a male screw portion (212) formed at one end of the horizontal member (210) and a rope hole (214) formed at the other end for tying the rope of the gimbal, and the inner and outer connecting members (200a, 200b) are manufactured with a hollow interior by blow molding.

[0038] Meanwhile, although not specifically illustrated, it is desirable to form anti-loosening teeth at the ends of the male screw portions (212) at both ends of the above-mentioned horizontal member (210) and the female screw portions (310, 320) on both sides of the connecting socket (300), as disclosed in Patent Document 5, which is the applicant's prior registered patent, so that after screwing in one direction, the anti-loosening teeth maintain an engaged state, thereby preventing the screw connection from becoming loose or unscrewed due to external force, so that the connection state does not become unstable even if it is continuously subjected to impact by waves while floating on the water surface.

[0040] In the embodiment illustrated in the drawing, the horizontal member (210) and the vertical member (220) of the inner and outer connecting member (200) are formed to be perpendicular to each other, but the present invention is not limited thereto. The vertical member (220) may be formed diagonally as in a truss structure, or may be formed to intersect in an X shape between two parallel horizontal members (210). Of course, the connecting member (200) that connects a pair of spaced-apart buoyancy bodies (100) and supports the gimbal may be manufactured in various forms to improve bending rigidity or torsional rigidity, and the outer diameter or number of the vertical member (220) may be designed in various specifications as needed.

[0042] The above-mentioned connecting socket (300) is manufactured by injection molding, and on both the left and right sides of the single-tube body, a female screw section (310, 320) of a left-hand screw type and a female screw section (310, 320) of a right-hand screw type and a tooth (not shown) for preventing loosening are formed, and on the outside, a tool groove (330) is formed radially to facilitate tightening using a tightening tool, and on the outer edge, an anti-slip protrusion is formed so that tightening work can also be performed using another tightening tool or hands.

[0044] The buoy assembly for seaweed farming of the present embodiment configured as described above has the advantage of being able to minimize labor and time required for assembly work by separately manufacturing a pair of left and right buoyancy bodies and inner and outer connecting rods using injection molding and blow molding methods, respectively, and then combining the buoyancy bodies into a single unit using a connecting socket with a structure similar to the body of a turn buckle after undergoing a separate fusion process, thereby completing assembly quickly and simply. Furthermore, since the connecting socket is prevented from loosening by means of anti-loosening teeth, it can sufficiently withstand external forces such as waves continuously received from the water surface, thereby stably supporting the seaweed net. Additionally, since the buoyancy bodies as well as the inner and outer connecting rods are hollow, they can exert auxiliary buoyancy to support the seaweed net. Moreover, since the buoyancy bodies and inner and outer connecting rods can be densely stored and transported in an unassembled state after manufacturing, it can resolve issues such as reduced marketability and reduced durability due to ultraviolet rays, as well as increased logistics costs, which would otherwise occur if the assembled volume were to be left outdoors.
