Description

Detailed Description of the Invention 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a structure and method for attaching mooring lines to a floating fish reef floating near the sea surface.

[Conventional technology]

There are two main types of fish reefs: bottom-type fish reefs, which are made of concrete or steel and are installed on the seabed, and floating fish reefs, which are floating on the sea surface or near the sea surface. It is used as an effective means to collect insects in the stomachs of (habitating fish).

By the way, this floating fish reef is generally constructed by connecting a floating fish reef main body 21 having a buoyant body to an anchor member 22 installed on the seabed with a mooring line 24 via a connecting fitting 23 such as a hook, as shown in the conventional example in FIG. Of these, the mooring cables 24 are particularly important components for anchoring the floating fish reef body at a predetermined floating position. For this reason, sufficient attention must be paid to its durability, and even if synthetic ropes are used that are seawater resistant, lightweight, and have high tensile strength, there is a risk of damage or breakage if used for a long period of time. For some reason, I try to replace this regularly.

Therefore, conventional methods for replacing the mooring ropes 24 with new ones include hoisting the entire floating fish reef, that is, all of the floating fish reef body 21, the anchor member 22, and the mooring ropes 24, to a barge using a crane ship or the like, or Here, the old mooring cable 24 is removed from the floating fish reef body 21 and the anchor member 22 and replaced with a new one, or the replacement work is performed by diving to the seabed.

[Problem that the invention seeks to solve]

The method of pulling up a floating fish reef on a barge or on land requires a large amount of money to pull up the entire floating fish reef, and reinstalling the entire reef is a large-scale work.

In addition, when replacing the cable by diving, there is an advantage that the cable can be replaced while the fish reef is still installed, but the diver must go deep to the seabed, which is dangerous.

An object of the present invention is to solve the above-mentioned disadvantages of the conventional example, and to provide a mooring rope for a floating fish reef that allows only the mooring rope to be easily replaced while the floating fish reef main body and anchor part are installed as they are, and that this replacement work can be done inexpensively and safely. and to provide a method for exchanging it.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention constitutes a mooring cable consisting of new and used main ropes and auxiliary ropes that run along these amphipod ropes and are attached so that their ends can be anchored to the ends of each main rope. death,
To replace the mooring line with a new one, wrap the middle of the mooring line in use around a drum provided on an anchor member installed in the sea, and attach both ends to the main body of the floating fish reef so that it can be moored.
Attach one end of the new mooring rope to the floating fish reef body, remove the sub-rope in use from the main rope, connect the other end of the new mooring cable to one end of the sub-rope, and pull up the other end of the sub-rope. The main idea is to connect the other end of the new mooring cable to the body of the floating fish reef above the drum.

[Effect]

According to the present invention, a mooring rope consisting of a main rope and an auxiliary rope along the main rope is wound around the drum of the anchor member on the seabed, and both ends are attached to the floating fish reef body to prevent the floating fish reef body from drifting. Tether at or near the sea surface. To replace this mooring line with a new one, first attach one end of the new mooring line to the body of the floating fish reef, connect the other end to one end of the old sub-rope, and pull up the other end of the old sub-line. While the main body is suspended in a predetermined position by the old main rope, a new mooring rope can be automatically stretched following the old auxiliary rope.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a front view showing an embodiment of a mooring line for a floating fish reef according to the present invention. In the figure, 1 indicates a floating fish reef body which itself has buoyancy. hook 2a,
2b were attached at appropriate intervals.

Further, numeral 3 in the figure is an anchor member such as a 5viW or concrete block installed on the seabed, and a rotating drum 4 is erected on the upper surface of the anchor member.

In the figure, numeral 5 indicates a mooring rope, which is made of chemical fiber because it is excellent in seawater resistance, lightweight, and has high tensile strength, and is approximately the same length as the main rope 6. The main rope 6 and the auxiliary rope 7 along the main rope 6 are set as one thread, and connecting fittings 8a and 8b, such as shankles, are attached to both ends. In this case, the main rope 6 is firmly fixed to the connecting metal fittings 13a and 3b so as not to get close to each other, but the auxiliary rope 7 is attached so that it can be attached.

In this way, the middle of the mooring cable 5 is wound around the drum 4, and the connecting fittings 8a and 3b at both ends are connected to the hooks 2a, respectively.

2b, and the floating fish reef body 1 is tied to the anchor member 3 with the mooring rope 5.

Next, a method of replacing such a mooring line will be explained. The new mooring rope 5' to be replaced with the mooring rope 5 currently in use will be made into a single thread consisting of the main rope 6' and the auxiliary rope 7' that runs along it in the same way as the mooring rope 5 currently in use, with connecting metal fittings at both ends. 8a',
Install 3b'.

Then, a new mooring line 5' is loaded onto a work boat 9 such as a fishing boat, transported to the sea where the floating fish reef is floating, and the user dives holding one end of this mooring line 5' to remove the floating fish reef body 1. First, one end of the new mooring cable 5' is fixed to the floating fish reef body 1 by connecting the connecting fitting 8b' to the hook 2a attached to the lower surface (see Fig. 2a), and the other end is lowered into the sea.

Next, connect only the secondary rope 7 of the mooring rope 5 in use with the connecting fitting $a, 3.
b, and one end is connected to the connecting fitting 8b' at the other end of the new mooring rope 5' lowered into the sea, and the other end of the sub-rope 7 is pulled up and loaded onto the work boat 9. The lobe is wound on the winding drum 10. Then, when the drum 10 is rotated to wind up the sub-rope 7, the new mooring line 5' connected thereto is pulled by the sub-rope 7 and gradually sinks into the sea (see Figure 2b). After passing through the drum 4 and being wound there, it is further pulled by the auxiliary cable 7 and then rises.

When the joint between the new mooring rope 5' and the old sub-rope 7 is located near the hook 2b of the floating fish reef body 1, the joint is released and the connecting fitting 8b' of the mooring rope 5' is connected to the hook 2b.
(See Figure 2C).

In this state, the main rope 6 of the old mooring rope 5 and the new mooring rope 5' are stretched between the floating fish reef body 1 and the drum 4.

Next, to remove the old main rope 6, attach the lower end of the old auxiliary rope 7 used to pull up the new mooring rope 5 to the old main rope 6.
The connecting fitting 8b (or 8a may be used) attached to one end is removed from the hook 2b and coupled thereto, and the connecting fitting 8a at the other end is also removed from the hook 2a to leave it in a free state.

In this state, if the old sub-rope 7 is further wound with the drum 10,
Following the secondary rope 7, the main rope 6 is also pulled up, wound around the drum 10, and recovered on the work boat 9. In this way, the old mooring rope 5
The replacement with a new mooring line 5' is completed.

In addition, in the above embodiment, the floating fish reef main body 1 and the anchor member 3

The method of exchanging the mooring rope 5 with a new one is the same as in the previous embodiment, and it is sufficient to connect the end of the new mooring rope to the end of the old sub-rope and pull up the old sub-rope.

In addition, as shown in FIG. 4 as a third embodiment, the attachment positions of the hooks 2a and 2b to the floating fish reef body 15 are set to the floating fish reef body 1.
In this case, the mooring line 5 can be replaced on the sea surface, so there is no need to dive underwater, and the work can be done more easily and safely. In the figure, reference numeral 15a denotes a hole drilled approximately in the center of the floating fish reef body 15 through which the mooring cable 5 is inserted.

〔Effect of the invention〕

As described above, the floating fish reef mooring line and its replacement method of the present invention allow the floating fish reef to remain floating at the installation site without being pulled up on board or on land when replacing the mooring line with a new one. It can be easily replaced in any condition and has good work efficiency. Furthermore, since there is no need to pay for pulling up, the replacement work can be done inexpensively and safely.
