KR-20260065246-A - FLOAT FOR LAVER FARMING

Abstract

The present invention relates to a buoyant device installed on both sides of a seaweed raft used for floating seaweed farming to generate buoyancy. Specifically, it is manufactured by blow molding with synthetic resin to replace the existing styrofoam buoyant device, and a multi-stage reinforcing section (130) is formed in a concentric manner on the edge portion between the outer surface (110), which becomes thinner during blow molding, and the left and right sides (120), so as to prevent deformation or damage caused by external force.

Claims (5)

1. A seaweed cultivation buoy in which a seaweed buoy (10) is connected to the outside with a rope (20) to form a seaweed buoy. The above-mentioned buoy (100) is blow-molded to form a cylindrical or polygonal shape and has a hollow interior, and a rope groove (112) is formed on the outer surface (110) where the slab (10) is connected by a rope (20), and a multi-stage reinforcing section (130) is formed in a concentric manner on the rim portion connecting the outer surface (110) to the left and right sides (120) so as to prevent deformation or damage by external force.
2. In claim 1, The above reinforcing part (130) is characterized by being formed in the shape of a sine wave having a predetermined radius of curvature, with three inwardly recessed parts and four outwardly protruding parts extending in a right-angle step shape or diagonally.
3. In claim 1, A buoy for seaweed farming characterized by having a rope hole (114) formed on the outer side of the rope groove (112) to prevent the rope (20) from coming off.
4. In claim 3, A buoy for seaweed farming characterized in that two rope holes (114) are formed at both ends of the rope groove (112).
5. In claim 1, The above-mentioned buoy for seaweed cultivation is made of polypropylene or polyethylene resin and is characterized by having its opening closed while compressed air is injected into the interior during the blow molding process, thereby maintaining the pressure inside the buoy higher than atmospheric pressure.

Description

Float for laver farming The present invention relates to a buoy installed on both sides of a seaweed raft used for floating seaweed farming to generate buoyancy. Specifically, it is manufactured by blow-molding a synthetic resin to replace the existing styrofoam buoy, and by forming concentric reinforcing members in multiple stages on the rim portion between the outer surface and the side, where the thickness becomes thin during blow-molding, the structural strength of the rim portion is improved so that it does not easily deform or break even when subjected to external force. Thanks to the Korean Wave, seaweed exports exceeded 1 trillion won last year (2023), setting an all-time record and even earning the nickname "black semiconductor." In order to solidify its position as a safe food, facilities for seaweed farming are also trending toward becoming more eco-friendly. Meanwhile, floats that support floating aquaculture nets for mass cultivation of seaweed in the sea by buoyancy are tied with ropes to the left and right sides of the bamboo or resin pipes that support the seaweed nets, and serve to maintain the seaweed nets floating on the water surface. These floats are typically made of styrofoam, but they have the disadvantage that delamination occurs or buoyancy gradually decreases due to water absorption and moisture content. Moreover, it is reported that as the styrofoam breaks into small pieces, it causes marine debris problems and increases the microplastic content in the seaweed itself. Accordingly, injection-molded plastic parts made of synthetic resin are widely used these days. When injection-molding parts made of synthetic resin, the part requires a process of dividing it into two parts, molding each part separately, and then joining the two parts. In this case, not only is an additional joining process required, but there is also a risk of leakage at the joint. To solve these problems, plastic floats using blow molding are being developed. Patent Document 1 discloses a buoy produced by blow molding, wherein a rope groove in which a rope can be seated and a saddle groove in which a saddle is seated are formed on the outer surface of the buoy. The rope groove and the saddle groove are formed together during the blow molding of the buoy. Meanwhile, the buoy produced by blow molding as in Patent Document 1 has the advantage of not requiring a joining process compared to the conventional method of injection molding by dividing it into two parts, but the strength is somewhat lower due to the characteristics of blow molding. Accordingly, when a rope is used to fasten a float to a blow-formed float, if the rope is tightened too strongly, the shape of the float is deformed. In addition, during blow forming, the rim portion between the cylindrical outer surface and the generally flat left and right sides becomes relatively thinner than other parts. As a result, the strength is reduced, causing the cylindrical float to become deformed and crushed during actual use, or the rim portion formed relatively thinner than other parts may be easily damaged by external force. Patent Document 2 describes a method of wrapping a separate body reinforcement means around the rope binding groove to prevent deformation or damage of the blow-molded buoy, but this had the problem of incurring significant additional costs in the production and assembly of the gimbal gimbal, as not only had to be manufactured separately as a band-shaped body reinforcement means, but also had to be installed during the process of binding the gimbal gimbal to the buoy using a rope. In addition to this, Patent Documents 3 and 4 also present eco-friendly buoys that can replace styrofoam buoys, but they are not significantly related to the buoy using blow molding of the present invention. FIG. 1 is a perspective view of a buoy for seaweed cultivation according to a first embodiment of the present invention. FIG. 2 is a front view of the seaweed farming float shown in FIG. 1. FIG. 3 is a front view showing the state in which the two sides of the gandapdae are bound with ropes, FIG. 4 is a perspective view of a buoy for seaweed cultivation according to a second embodiment of the present invention. Figure 5 is a front view and an enlarged view of the key parts of the seaweed farming float shown in Figure 4. Hereinafter, preferred embodiments of the present invention that do not limit the invention will be described in detail with reference to the attached drawings. FIGS. 1 to 3 illustrate a float according to the first embodiment of the present invention and a state of use thereof. In the float (100) according to the present embodiment, a rope groove (112) is formed on the outer surface (110) so that a gimbal gimbal (10) is connected to the outside with a rope (20) to form a gimbal gimbal. The float (100) is blow-molded to form a cylindrical shape and has a hollow interior, and a multi-stage reinforcing section (130) is formed concentrically on the
