Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an anchor structure laid on the seabed for anchoring a buoy system, and more particularly to a split type anchor structure configured to be changeable to a desired underwater weight. It is a thing.

[Conventional technology]

Conventionally, this type of anchor has the underwater weight necessary to put the buoy system into the sea from the work boat, sink it to the sea floor, and moor it, and its size and shape should be as compact and fluid resistance as possible. The one manufactured as an integrated structure was used.

Fig. 2 is a schematic diagram showing a buoy system that is sunk and moored on the sea floor. An anchor 1 with an integral structure is sunk on the sea floor, and an anchor 1 is connected with an audio device 3 by a mooring rope 2 and levitated to the sea surface. It is anchored in the water by the buoy 4.

FIG. 3 is an external perspective view showing a structure of an anchor used in such a buoy system, and the anchor 1 has a connecting hook 1b integrally provided on an upper portion of a main body 1a.

[Problems to be solved by the device]

However, in the anchor device having the above configuration, when the buoy system becomes large, the anchor to be used also needs to have a large size and a large underwater weight.
There is a drawback that loading work on the work boat and moving from the hangar to the anchor loading work place set on the deck of the work boat cannot be easily performed. Therefore, in order to carry out such work, it is necessary to install a crane on the work ship and ancillary equipment such as a transportation jig, which causes a problem that the cost for operating the buoy system is significantly increased. ,
Further, since the anchor is integrated, there is a drawback that the underwater weight of the anchor cannot be changed after sailing to the laying site.

The present invention has been made in view of the problems of the conventional technique, and an object thereof is to provide an anchor having a structure that can be easily moved to a necessary place by one person without using special equipment. It is what

[Means for Solving the Problems]

In order to achieve the above object, the anchor structure of the present invention comprises:
For anchors laid on the seabed and anchoring a buoy system, multiple anchors consisting of chains are installed side by side so that a predetermined weight can be obtained, and the groups of anchors that are installed side by side are connected in the shape of goodwill with connecting lines. A shackle is attached to the connecting end of the connecting line.

It is preferable that the connecting cords are provided with connecting wheels at both ends, one connecting wheel is inserted through the other connecting wheel, and the shackle is attached to the protruding other connecting wheel.

[Action]

According to the present invention, since the anchor is constructed as described above, when the buoy system is activated, the upper buoy and the lower anchor generate vertical tension, so that the connecting rope tightens the anchor single group. work. In addition, disassembling and assembling becomes easy, and by increasing or decreasing the number of anchors alone, an anchor with a desired underwater weight can be easily obtained, and even a single worker can disassemble the hangar. Work such as loading and unloading to and from the work boat can be performed easily. Furthermore, it is possible to change the underwater weight of the anchor even after sailing to the laying site. Therefore, the installation of the crane on the work boat and the auxiliary equipment such as the transportation jig are levitated, and the operating cost of the buoy system is significantly reduced, so that the above problems can be eliminated.

〔Example〕

 Hereinafter, embodiments will be described with reference to the drawings.

FIG. 1 is a schematic configuration diagram illustrating an embodiment of the present invention. In the figure, the anchor body 11 is laid by using a plurality of anchor single bodies 12 each having a chain cut into a length that can be held by one person (a maximum weight of 20 to 25 kgf). It is the one that generated the underwater weight necessary for. In this case, a plurality of anchors arranged side by side are sequentially inserted into the upper terminal rings 12a of the plurality of anchors 12 constituting the anchor body 11 by sequentially connecting the connecting cords 13 having the connecting wheels 13a and 13b. It is desirable that the unitary body 12 is incorporated in the shape of goodwill, the other connecting ring 13b is inserted into one connecting ring 13a of the connecting line 13, and the shackle 14 is attached to the protruding connecting ring 13b. With this configuration,
13 is the anchor body 11 in the shape of goodwill due to vertical tension.
Tighten and secure and hold it securely.

In addition, the connecting cords 13 are long enough to surround and tie the required number of anchors 12 arranged side by side, and the connecting wheels 13 at both ends are connected.
It is also possible to join a and 13b and attach the shackle 14 to both wheels 13a and 13b.

Further, the means for connecting the single anchor groups in the shape of goodwill and attaching the shackle is not limited to the connecting rope in the previous term, and may be any one that achieves the same purpose.

[Effect of device]

As described in detail above, according to the present invention, the following effects can be obtained.

Moving the anchor on the work boat For example, when moving from the anchor hangar of the work boat to the anchor loading work place set on the deck, each component that constitutes the anchor has a weight that can be easily held by one person and is disassembled. Since it can be easily assembled, it can be easily implemented without using special equipment such as a crane.

Further, the chain does not need to have a special shape, a commercially available one can be easily obtained, and the cutting cost can be reduced because it is simply cut into a predetermined length.

Further, when it becomes necessary to change the underwater weight of the anchor during the laying work, the anchor component is divided, so that it can be easily dealt with.
