Description

[Detailed description of the invention] This invention relates to a mooring body floating on the sea surface.

Conventionally, mooring bodies such as buoys are simply connected to a weight on the seabed via a mooring cable, but there is an inconvenience that the mooring position shifts laterally in response to changes in sea surface height due to ebb and flow.

To prevent this, as shown in Figure 2, the mooring body 1 that moves up and down
It is sufficient to attach a float 8' to one end of the mooring cable 6' installed at the mooring body 1', and balance the float 8' with the mooring rope 6' attached to the mooring body 1' through a pulley installed at the weight 2'. Since there is a considerable length to the seabed, the wire rope that is the mooring line 6' itself has a considerable weight, and this requires that the buoyancy of the float as well as the buoyancy of the mooring body itself is large. As the volume becomes larger, disadvantages arise such as rubbing against adjacent wire ropes when going up and down.

-This idea allows the float to be small,
Therefore, not only can the manufacturing cost be lowered, but also the cross-flow of the float due to ocean currents is reduced to prevent damage to various parts.Explaining the embodiment of this invention with reference to the drawings, in Fig. 1, 1 is A mooring body installed on the sea, made in the shape of a single ark or a frame with the periphery as a buoyant body, with necessary equipment such as a lighthouse, etc. in the center of the top surface.
Wind power generation equipment etc. will be erected.

2... is a weight sunk in the seabed, and a horizontal shaft 3 is rotatably supported on the upper surface, and a small diameter pulley 4 and a large diameter pulley 5 are fixed to the horizontal shaft. .

Mooring cables 6, 7 are wound around these pulleys 4..., 5... with one end attached to the appropriate position on the circumference thereof, and the other end of the mooring cable 6 of the pulley 4 is attached to the mooring body 1, and the pulley 5... A float 8 is connected to the other end of the mooring cable 7, and as the mooring body 1 rises, the float 8
is pulled downward.

In addition, 9... are space|interval holding rods provided in each float 8....

This invention has the above structure, and at high tide, the small diameter pulley 4 is rotated by the rising mooring body 1 via the mooring cable 6.
The rotation of the large-diameter pulley 5 coaxial with this lowers the float 8 via the mooring rope 7, and at low tide, the mooring rope 6 of the mooring body 1, which descends, is connected to the pulley 5 rotated by the rising float 8. A coaxial pulley 4 winds the winding, and in this case, both pulleys 4 and 5
Since the radii of rotation are different from each other, the amount of elevation of the float 8 increases compared to the elevation of the mooring body 1, but the buoyancy of the float 8, which is the winding force, is very small.

In this way, the floats 8 need only be small, so as described above, they have little resistance to ocean currents and are easy to handle, and accordingly, the mooring ropes 6 can also be thin.

Note that although the amount of elevation of the float 8 increases compared to that shown in FIG. 2, the amount of elevation and descent of the mooring body 1 is only a small amount due to ebb and flow, so the amount of elevation of the float 8 to balance this is not so large. There's no need to make it a problem.

As described above, this invention allows the floats 8 to be made small, so even if the number of floats is increased as shown in Figure 1, there is no risk of the floats getting entangled with each other, and stable mooring can be achieved. be able to.
