The reserve buoyancy (the buoyancy obtained by subtracting the floating body's own weight and the underwater weight of the mooring line from the buoyant force of the underwater buoyant body) is taken to be considerably larger, and the vessel is moored to a sink such as a concrete block that has a considerably greater underwater weight, and then pulled into the water. Since it was moored, the underwater buoyant body has a large reserve buoyancy, so it becomes a large buoyant body, and in order to pull the buoyant body against this large reserve buoyancy and stably moor it, its sinker is also a heavy sinker. I was getting used to it.

係留装置に関する。以下図面に従つて詳述する。 The present invention relates to a mooring device for an underwater buoyant body in which the buoyancy force obtained by subtracting the weight of the underwater buoyant body is equal to the underwater weight of the mooring cable, and the sizes of the buoyant body and sinker can be made as small as possible. The details will be explained below with reference to the drawings.

いる。 The drawing shows one embodiment of the present invention, and the underwater buoyant body 1 is shown at a depth of water.
It is moored underwater at a depth of h d . The one mooring line is a thin mooring line 2 (wire rope, synthetic fiber rope, etc.) with a light weight per unit length from the mooring ring 6 of the buoyant body to a depth of ld from the water bottom, A mooring cable 3 such as a thick, heavy chain or the like is laid on the bottom of the water with extra length, and an anchor or a sinker 4 is connected to its tip.

くなるよう設定する。 The weight of the underwater buoyant body is W, and the buoyancy is P (of course P>W)
The underwater weight of mooring line 2 is W 2 , and the weight of mooring line 3 is ld
If the underwater weight of the long part is W 3d , then the relationship of P-W = W 2 + W 3d is established, that is, the buoyancy (P-W) obtained by subtracting the self-weight of the underwater buoyant body is the mooring force above the bottom rising point 5. Set to be equal to the underwater weight of cables 3 and 2 (W 2 + W 3d ).

るだけで釣合つて水中浮力体は静止する。 In this way, the buoyant force obtained by subtracting the weight of the underwater buoyant body is equal to the actual underwater weight of the mooring line, and the extra buoyant force becomes unnecessary. The weight may be a small-capacity anchor or a concrete block. Also, since there is extra length in the chain, etc., even if the size of the buoyant body changes slightly from what was planned, the underwater buoyant body will remain stationary due to a slight change in the length of ld.

大変有効である。 In this way, for underwater buoyant bodies that are installed in large numbers like fish reefs, there is no need to worry too much about manufacturing accuracy, and the very economical mooring device for underwater buoyant bodies of the present invention is very effective.
