Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a floating type stabilizing device for seaweed nets for aquaculture.

<Problems to be solved by this invention> In deep seas and areas where the seabed is rocky and it is impossible to set up supports for seaweed nets, the seawater is clean and rich in nutrients. We devised a method of cultivating seaweed, but there was a problem in that the seaweed net could be exposed and submerged autonomously on the sea surface, and if the anchor line slackened due to low tide and there were strong winds and waves, it would cause a large flow in the direction of the wind and waves. As a result, maintenance and management of the seaweed nets became difficult and the seaweed nets ceased to have an infestation effect. The present invention attempts to solve such problems.

<Structure of the invention> In the present invention, a horizontally long seaweed net is arranged with a distance between two triangular floating trunk bodies, and both ends of the seaweed net line at both longitudinal ends of the seaweed net are connected to the floating trunks. connected to one end of a long anchor wire extending over the body and disposed outward from the top of the floating trunk body, having straight edge portions spaced apart below the seaweed net lines at both ends; A vertical floating device with a semicircular shape in plan view with a vertical prop from the center of the upper surface of the body side with a propensity for self-inversion is hung with the straight edge facing one of the floating trunks, and each Both ends of a connecting line, which has a binding part on the right edge and the bottom of the device and is wired under both longitudinal ends of the seaweed net, are attached under the inner end of the floating trunk body, and the other end of the anchor wire is A floating seaweed net stabilizing device is characterized in that a floating device is inserted into an anchor hole of an anchor, a underwater flotation device is attached to the tip of the insertion, and a restraining device is attached to the middle of the anchor wire.

<Example> Examples will be described below based on the drawings.

Floating bamboos 3 are installed transversely at regular intervals in the narrow width direction of the lower surface of an oblong seaweed net 4, and lying floats 5 are suspended below both ends of each floating bamboo 3. Each of the lying-down floats 5 has a thick plate body 5d that is semicircular in plan view, with a straight edge part 5b on one part and a circular edge 5c on the other part, and the center of the upper surface on the straight edge part 5b side. More pillar 5
A is planted, a main shaft pipe 6 is horizontally attached to the upper end of the support 5a, and the floating bamboo 3 is inserted and suspended.
As shown in FIG. 2, the straight edges 5b of each of the lying floats 5 are aligned toward one of the longitudinal directions of the seaweed net 4, and each of the lying floats 5 is aligned at the center of the straight edge 5b. Front hanging tool 5', lower hanging tool 5'' is installed under the support 5a on the bottom of plate 5d, and connecting line 7 is used to connect front and rear floating devices 5 between lower hanging tool 5'' and front hanging tool 5'. (1st
figure).

The seaweed net 4 is placed on floating trunk bodies 1, 1' which are arranged at intervals outside both longitudinal ends of the seaweed net 4 by extending both ends of the seaweed wire 4a at both longitudinal ends outside the seaweed net 4. Each is connected to one end of the anchor wire 8. The floating trunk bodies 1, 1' are formed in the shape of a right-angled triangle and are arranged with the slope facing outward, and the two anchor lines 8 are provided with two hooks 2, one each at the top and bottom of the slope. 2', through the slope of floating trunk bodies 1 and 1', and immersed in the sea.
A stopper 9 is provided in the middle near the seabed, and the stopper 9
Anchor 1 that is tied together at the part and deposited on the seabed surface.
It passes through an anchor hole 10' provided in the anchor hole 10' and connects an underwater floating device 11 to the tip that passes through the anchor hole 10'. The inner lower end of the floating trunk bodies 1, 1' and the lower hook 5'' of the facing floating device 5 are also connected by a connecting line 7.The restraining device 9 is formed larger than the anchor hole 10' so that the anchor When facing the hole 10', subsequent insertion of the anchor wire 10 is prevented.

The seaweed net with the above structure is fixedly set up in sea areas where the water is deep and the seabed is rocky, making it impossible to erect supports to support the seaweed net.

However, as shown in Fig. 3, when the sea level A rises to _H1 due to high tide, the anchor wire 8 pulls up the underwater buoy 11 until it touches the anchor hole 10' and becomes tense, forming a right-angled triangle. seaweed net 4 through a shaped floating trunk body 1
In order to tension and pull up the seaweed net 4 in the longitudinal direction, the floating device 5 erects the support 5a, thereby lifting the seaweed net 4 to sea level H ₁
This results in support in a more exposed exposed state.
When the sea level drops to about _H2 , which is the normal water level, the anchor line 8 becomes entangled and moves downward, but the underwater flotation device 11 moves upward due to its buoyancy in the water, and the restraint device 9 closes to the anchor hole 1.
Since the tension state will continue until reaching 0', each floating device 5 will continue to be erected and the seaweed net 4 will continue to be exposed. When the sea level further falls and the anchor line 8 loosens, the tension in the seaweed net 4 also loosens, so the floating device 5, which originally has a tendency to lie down, is forced to lie down along with the support 5a, and the seaweed net 4 is sunk near the sea surface. Even if the sea level B reaches _H3 due to low tide, the anchor line 8 and the restraint 9 remain in the anchor hole 1.
Since the underwater buoy 11 acts as a buoyant force, the range of its slack is kept to a small extent, so the seaweed net 4 will not be washed away significantly even if the wind and waves are strong.

<Effects of the invention> In this way, the present invention makes it possible to use anchors to set up seaweed nets in the deep sea or areas where the seabed is rocky and impractical to set up supports. Since the seaweed net is placed on both sides and movable and connected to the underwater floating device, the seaweed net is exposed and submerged regularly and autonomously, and even at low tide when the anchor line slackens, there is a device to prevent it from loosening. Since the water is regulated using an underwater flotation device, it has many effects such as securing the original position without being washed away and making maintenance management more stable.
