Also, a locking ring that slides up and down along the support can be used to attach oysters to the support. is prevented from occurring.

(3) Problems to be Solved by the Invention However, the plastic locking ring attached to the pole does not have sufficient buoyancy, and floating bamboos are tied to the seaweed net at appropriate intervals. It is floating. However, the seaweed nets spread out on the sea surface must be regularly disinfected to prevent the growth of bacteria, and the seaweed nets must be regularly disinfected to prevent the growth of bacteria.
They carry out various work such as replacing seaweed nets.
Floating bamboo tied to the seaweed net was removed, the seaweed net was brought back to the work boat, and work such as disinfection, nori picking, and relining was carried out.
After the work is completed, the floating bamboo is tied back to the seaweed net and stretched out on the sea surface, which poses problems such as requiring a lot of effort to remove and attach the floating bamboo from the seaweed net.

The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to provide a buoyancy body on a locking ring inserted through a support column so that the ring slides along the support support along with the seawater surface. Is it possible to use a locking ring that connects the seaweed net with sufficient buoyancy without attaching floating bamboo to the seaweed net? To provide a seaweed net support device which is floatingly supported on the water surface and can efficiently carry out various operations such as disinfecting the seaweed net, picking seaweed, and lining it up without requiring much effort.

■9 Structure of the Invention (1) Means for Solving the Problems In order to achieve the above object, the present invention provides a pillar 12 erected on the seabed to support the seaweed net 26, and a sliding structure on the pillar 12. It includes a locking ring 14 that is loosely fitted, and a buoyancy device 16 that is also loosely fitted to the support column 12 on the lower surface of the locking ring 14, and the buoyancy of the buoyancy device 16 causes the locking ring 14 to move freely. The device is composed of a seaweed net support device 10 in which a seaweed net 26 is suspended on the seawater surface and linked to a locking ring 14 while sliding along a support along the dry water surface.

(2) Function The present invention is a seaweed net support mechanism consisting of a locking ring loosely fitted to a support, in which a flotation device that slides up and down along the support is loosely fitted to the lower surface of the locking ring. , the locking ring received by this buoyancy device floats along with the seawater surface, and the seaweed net moored to the locking ring with the wires floats above the seawater surface without attaching floating bamboo, and the seaweed net It becomes extremely easy to handle the seaweed net during various types of work.

(3) Embodiments Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

FIGS. 1 and 2 show a seaweed net support device 10 according to an embodiment of the present invention. In FIG. The locking link 14 is provided with a locking link 14, and a buoyant device 16 is loosely fitted to the support column 12 on the lower surface of the locking link 14.

As shown in FIGS. 3 and 4, the locking ring 14 includes a ring body I8 made of plastic or the like, and a plurality of locking holes protruding from the outer peripheral surface of the ring body 18 at radially symmetrical positions. It has a protrusion 20.

As shown in FIGS. 5 and 6, the buoyancy device 16 is made of an annular body 24 made of plastic or the like and having a sealed space 22 therein.

This buoyant device 16 may be any device as long as it can float the seaweed net connected to the locking ring on the sea surface with sufficient buoyancy, and instead of being a hollow annular body as described above, it is made of a light material such as cork or foam material. It may be formed into

As shown in FIGS. 1 and 2, when the seaweed net 26 is stretched onto the seaweed net support device 10, the vertical floating width of the buoyancy device 16 and the locking ring 14, which are loosely fitted to the support column 12, is restricted. Both ends of the regulation string 28 are tied to the upper end of the support 12 and to a position spaced a predetermined distance from the upper end. Then, as shown in FIG. 7, the master rope 30 is tied to the locking hole protrusion 20 of the locking ring 14 on the side of the seaweed net 26 between each of the pillars 12, so that the pillars 12 are interconnected. The child line 32 on the side of the seaweed net 26 is connected to the locking hole protrusion 20 of the locking ring 14 of the support 12.
The seaweed net 26 is then tied to the seaweed net 26 in sequence.

This stretched seaweed net 26 is maintained at sea level because the locking ring 14 of the seaweed net support device IO provided on each support column 12 slides up and down along the support column 12 with the ebb and flow of seawater due to the buoyancy of the buoyancy device 16. In addition, during operations such as disinfecting the net 26, picking seaweed, or relining the seaweed, the protrusion 20 with the locking hole of the locking ring 14 This allows the pre-adjustment 32 to be removed and the seaweed net 26 to be hoisted to the work boat in its original condition, and there is no need to attach floating bamboo to the seaweed net 26, so the seaweed net 26 that is being stretched out on the sea surface can be lifted. Various processing operations can be performed efficiently.

In addition, since the locking ring 14 slides along the support 12, oysters do not adhere to the support 12, and when the seawater temperature rises, the locking ring 14 can be slid to the upper end of the support 12. By pulling up the seaweed net 26 from the sea surface while securing it with a string, it is also possible to prevent the rotting of the growing seaweed.

■■1 Effects of the Invention As explained above, the seaweed net support device of the present invention has a flotation device (loosely fitted to the support) on the lower surface of the locking ring loosely fitted to the support for deploying the seaweed net. The seaweed net, which is deployed using a buoyancy device and supported by a locking ring, is made to float on the seawater surface, and there is no need to attach floating bamboo to the seaweed net and float it on the seawater surface. Work such as disinfection, picking seaweed, and relining can be done easily and efficiently.

In addition, the locking ring that slides along the support prevents oysters from attaching to the support, and when the seawater temperature rises, the locking ring can be slid to the top of the support and locked with a string. At the same time, the seaweed net can be lifted from the sea surface to prevent the growing seaweed from rotting.
