Description

  The present invention relates to an algae-growing net that protects the algae-growing environment formed on the water bottom or reef material.

  Various methods are known as methods for growing algae in water. For example, a region in which algae spores and algae themselves are attached to reef materials installed in water to grow algae on reef materials (hereinafter referred to as algae). , Which is also referred to as an algae growing region), and a method for growing algae on the reef material by installing such a reef material in water is known. However, in the water where many organisms (predatory organisms) that feed on algae live, it is difficult for algae to grow on reef materials.

  Then, in order to protect the algae on a reef material from predatory organisms and to form the environment which is easy to grow algae, the method of enclosing an algal growth area | region with a net is proposed (refer patent document 1). In such a method, intrusion of predatory organisms into the net is prevented by the net, so that algae on the reef can be prevented from becoming food for the predatory organisms. Thereby, the environment which is easy to grow algae on reef material is formed.

JP 2007-6796 A

  As a configuration of the net used as described above (hereinafter also referred to as algae-growing net), for example, a net-like member formed in a net-like shape, and a parent rope that is thicker than a child rope constituting the net-like member, What is provided with the binding rope which binds the master rope to the net-like member is known. In such an algae-growing net, the master rope is arranged along the outer periphery of the mesh member, and the master rope is bound to the master rope and the end portion of the mesh member (specifically, the end portion of the child rope). .

  And when enclosing an algal growth region using such a net for algae growth, for example, a plurality of pillar materials are installed around the algal growth region, and adjacent column materials so as to surround the algal growth region A net for growing algae is stretched between them. Thereby, the algae growing region is surrounded by a plurality of algae growing nets. At this time, the end of the algae-growing net is connected to the pillar material, but at the end of the algae-growing net, the master rope is bound by the binding rope to the end of the sub rope constituting the net member. For this reason, there is a possibility that the binding portion will come off from the end of the child rope, and the net member and the parent rope will be separated.

  Thus, if the mesh member and the master rope are separated, predatory organisms enter the algae-growing net from between the end of the mesh member and the master rope, and the environment for growing the algae is impaired. . For this reason, it is requested | required that a net-like member and a master rope should be united strongly.

  Therefore, the present invention provides an algae-growing net that can effectively prevent the invasion of predatory organisms into the algae-growing region by preventing the net-like member and the master rope from separating. Is an issue.

  The algae-growing net according to the present invention is an algae-growing net that is arranged so as to surround a region for growing algae formed on the water bottom or reef material and protects the algae-growing environment, and is formed in a net shape. A mesh member, a master rope thicker than the sub rope constituting the mesh member, and a binding rope for binding the mesh member and the master rope, the mesh member having an end portion located on the center side A folded end portion formed by folding is provided, and the master rope is bound by a child rope and a binding rope located at the folded end portion.

  According to such a configuration, the master rope is bound by the binding rope to the sub rope located at the folded end of the mesh member, so that the binding between the mesh member and the master rope can be strengthened. Specifically, since the folded end is formed by folding the end of the mesh member, the end of the cord that constitutes the mesh member is not located at the folded end. That is, since the master rope is bound to a position other than the end of the child rope, it is possible to prevent the parent rope from coming off from the end of the child rope. This prevents the mesh member and the master rope from separating, so that predatory organisms can be effectively prevented from entering the area surrounded by the alga growing net.

  The folded end is preferably formed over the entire outer periphery of the mesh member, and the master rope is preferably bound over the entire folded end.

  According to such a configuration, the outer periphery of the algae-growing net can be given rigidity by the master rope. For this reason, the workability | operativity at the time of arrange | positioning the algae growth net | network around the algae growth area | region can be improved. In addition, since the parent rope is located at the end of the algae-growing net, connecting the end of the algae-growing net to the reef material etc., the portion of the child rope of the algae-growing net is reef material. The connection strength can be increased as compared with the case of being connected to each other.

  It is preferable that a plurality of pillar materials are installed around the area where the algae is grown, and the master rope is bound to a child rope located in a region where the mesh member overlaps with the pillar material.

  According to such a structure, damage to the net for algae growth can be suppressed by binding the master rope via the binding rope to the sub rope located in the region where the mesh member and the pillar material overlap. Specifically, since the algae-growing net comes into contact with the pillar material in an area overlapping with the pillar material, the master rope is bound to such an area, so that only the net-like member is present in such an area (that is, The strength of such a region can be improved as compared with the case where only the child rope is located. For this reason, breakage of the algae growth net due to contact with the pillar material can be effectively suppressed.

  The cord is composed of an outer shell made of a thermosetting resin and a core portion wrapped with the outer shell, and the folded end is in a state where the end of the mesh member is folded. It is preferable that the mesh member is formed by heating.

  According to such a configuration, the shape of the folded end portion can be satisfactorily maintained by configuring the outer shell of the baby rope from the thermosetting resin. Specifically, the end portion of the mesh member is folded, and the child rope is deformed in the folded portion. And, since the outer shell of the deformed portion of the baby rope is cured by heating the mesh member in such a state, the shape of the deformed portion (that is, the shape of the folded end portion) can be satisfactorily maintained. it can.

  As described above, according to the present invention, it is possible to effectively prevent the predatory organisms from entering the algae growing region by preventing the mesh member and the master rope from separating.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  The algae-growing net according to the present invention is arranged so as to surround a region for growing algae formed on the water bottom or reef material (hereinafter also referred to as algae-growing region). In the present embodiment, as shown in FIG. 1, a plurality of algae-growing nets 1 are arranged around the algae growing area so as to surround the algae growing area formed on the reef material A. In the present embodiment, the algae growing region is disposed above the algae growing region so as to close the upper end opening of the side wall on the cylinder in which the plurality of algae growing nets 1 are arranged so as to surround the algae growing region. Net 1 is arranged. And the edge part of each net 1 for algae growth is connected, and it will be in the state where the algae growth area | region was covered with the net 1 for algae growth.

  In this embodiment, a plurality of pillar materials B are installed around the algae growing region. Then, the algae-growing net 1 is stretched between the adjacent pillar materials B, and the end of each algae-growing net 1 is fixed to the pillar material B with a fixture or the like. The shape (for example, cubic shape) formed by the net 1 is maintained. In the present embodiment, the reef material A includes a reef material A1 for growing algae and a reef material base A2 on which a plurality of the reef material A1 is placed.

  As shown in FIG. 2, the algae-growing net 1 has a net-like member 2 formed in a net-like shape, and is thicker than the child rope 2a constituting the net-like member 2 (for example, 5 times to 10 times the baby rope 2a). A master rope 3, and a binding rope 4 that binds the net member 2 and the master rope 3. The master rope 3 is disposed along the outer periphery of the mesh member 2 and over the entire outer periphery. In this embodiment, the master rope 3 is bundled with the sub rope 2a located in the area | region which overlaps with the pillar material B in the net-like member 2. FIG. Moreover, the binding rope 4 is wound around the child rope 2a and the parent rope 3 so that both the baby rope 2a and the parent rope 3 constituting the mesh member 2 are located on the inner side. And the master rope 3 are united.

  As shown in FIG. 3, the mesh member 2 includes a folded end portion 2 b formed by folding an end portion toward the center side. Then, the master rope 3 is bound to the folded end 2b. Specifically, out of the child rope 2a located at the folded end 2b, the child rope 2a (hereinafter, extending along the parent rope 3) extending along the outer circumferential direction of the mesh member 2 (hereinafter, the binding position child rope 2c). And the master rope 3 are united. In this embodiment, the binding position child rope 2c is located on the outermost peripheral portion of the mesh member 2 in which the folded end portion 2b is formed.

  The method for forming the folded end 2b is not particularly limited, but it is preferable to select appropriately according to the material constituting the child rope 2a. For example, when the baby rope 2a is constituted by an outer shell made of a thermosetting resin and a core portion wrapped by the outer shell, the mesh member 2 is arranged so that the end of the mesh member 2 is located inside. It is possible to employ a method of heating the mesh member 2 in a state in which is folded. As a result, the outer shell of the rope 2a constituting the mesh member 2 is cured, so that the shape of the position where the mesh member 2 is folded back is fixed, and the folded end 2b is formed.

  The thermosetting resin that constitutes the outer shell of the cord 2a as described above is not particularly limited, and examples thereof include phenol resin, epoxy resin, silicone resin, unsaturated polyester resin, polyimide resin, polyurethane resin, and the like. Is mentioned. Moreover, as a material which comprises the core part of the above-described cord 2a, a polyester resin, an acrylic resin, a vinyl chloride resin, a polyphenylene oxide resin, a polyamide resin etc. are mentioned, for example. In addition, the cord 2a may include a coating layer on the surface of the outer shell, and examples of the coating layer include polyethylene resin, polypropylene resin, polyamide resin, ABS resin, polyacetal resin, and vinyl chloride resin. .

  The baby rope 2a configured as described above is lightweight and has excellent corrosion resistance (durability). Furthermore, even if such a small rope 2a is a comparatively thin thing (phi5 mm or less), intensity | strength is comparatively high and it has moderate rigidity further. For this reason, the algae-growing net 1 provided with the net-like member 2 formed using such a baby rope 2a has good workability when placed around the algae-growing region, and the influence of water flow, etc. This makes it difficult to break and adheres to it.

  The size of the mesh of the algae-growing net 1 as described above is not particularly limited, but is appropriately determined according to the underwater environment (the size of the predator, the water flow, etc.) in which the algae-growing net 1 is installed. You can choose. For example, it is preferable to cover the algae growth region using a plurality of algae-growing nets 1 having different mesh sizes. Specifically, two algae-growing nets 1 having different mesh sizes are connected to each other. It is preferable that the net material is a set of net materials, and the algae-growing net 1 having a small mesh in the net material is disposed on the water bottom side, and the algae-growing net 1 having a large mesh is disposed on the water surface side and disposed around the algae growing region.

  The mesh size of the algae-growing net 1 arranged on the bottom of the water is not particularly limited, but is appropriately set according to the size of the predatory organisms that inhabit the vicinity of the bottom of the water. For example, the mesh size may be 10 mm to 40 mm, 10 mm to 30 mm, or 20 mm to 40 mm.

  As described above, according to the algae-growing net according to the present invention, it is possible to effectively prevent the invasion of predatory organisms into the algae-growing region by preventing the mesh member and the parent rope from separating. be able to.

  That is, by binding the master rope 3 by the binding rope 4 to the sub rope 2a located at the folded end 2b of the mesh member 2, the binding between the mesh member 2 and the master rope 3 can be strengthened. Specifically, the folded end 2b is formed by folding the end of the mesh member 2, so that the end of the cord 2a constituting the mesh member 2 is not located at the folded end 2b. That is, since the master rope 3 is bundled at a position other than the end of the child rope 2a, it is possible to prevent the parent rope 3 from coming off from the end of the child rope 2a. Thereby, since the net-like member 2 and the master rope 3 are prevented from being separated, the invasion of predatory organisms into the region surrounded by the algae-growing net 1 can be effectively prevented.

  Further, the parent rope 3 can give rigidity to the outer peripheral portion of the algae-growing net 1. For this reason, the workability | operativity at the time of arrange | positioning the algae growth net | network 1 around the algae growth area | region can be improved. Moreover, since the master rope 3 is located at the end of the algae-growing net 1, by connecting the end of the algae-growing net 1 to the reef material A or the like, the child rope of the algae-growing net 1 The connection strength can be made higher than when the portion 2a is connected to the reef material A or the like.

  Moreover, the master rope 3a is bound to the sub rope 2a located in the area | region with which the net-like member 2 and the pillar material B overlap, and the breakage of the algae-growing net 1 can be suppressed. Specifically, since the algae-growing net 1 comes into contact with the pillar material B in an area overlapping with the pillar material B, the master rope 3 is bound to such an area, so that a net-like member is provided in the area. Compared with the case where only 2 (that is, only the child rope 2a) is located, the strength of such a region can be improved. For this reason, the breakage of the algae-growing net 1 due to contact with the pillar material B can be effectively suppressed.

  Moreover, when the outer shell of the child rope 2a is made of a thermosetting resin, the shape of the folded end 2b can be favorably maintained. Specifically, the end portion of the net-like member 2 is folded, so that the child rope 2a is deformed in the folded portion. And since the outer shell of the deformed portion of the baby rope 2a is cured by heating the mesh member 2 in such a state, the shape of the deformed portion (that is, the shape of the folded end portion 2b) is maintained well. can do.

  The algae-growing net according to the present invention is not limited to the above embodiment, and various modifications can be made without departing from the gist of the present invention. Further, the configurations and methods of the plurality of embodiments described above may be arbitrarily adopted and combined (even if the configurations and methods according to one embodiment are applied to the configurations and methods according to other embodiments). Of course, it is of course possible to arbitrarily select configurations, methods, and the like according to various modifications described below and employ them in the configurations, methods, and the like according to the above-described embodiments.
