Abstract

PROBLEM TO BE SOLVED: To make a floating dock seated exactly on seating mounts without having the influence of tide. SOLUTION: This device is constituted so that a number of seating mounts 3 raised in two lines on the sea bottom for making a floating dock 1 seated may be surrounded by a surrounding wall 9 standing on the sea bottom 5 with the floating dock 1, and a water surface 8 in the surrounding wall 9 may be adjusted at an appropriate water level by pouring and draining means 10, 11. Therefore, even if the sea level outside the surrounding wall 9 is low, or the weight of a ship 6 installed inside the floating dock 1 is heavy, surfacing by the ballast drainage of the floating dock 1 in the surrounding wall 9 can be conducted appropriately all the time, thus it is possible to make the floating dock 1 seated exactly on the seat mount 3.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus provided with a seating stand erected on the sea floor and a floating dock which can be seated on the seating stand.

[0002]

2. Description of the Related Art As a conventional seating type floating dock device,
As shown in FIG. 3 (front view) and FIG. 4 (cross-sectional view taken along the line AA in FIG. 3), there are a large number of seats 3 erected in two rows on the seabed 5, A floating dock 1 is provided on the support surface so that the side protrusion 2 can be separably engaged with the side projection 2 to be seated thereon. A boat 6 is mounted on the floating dock 1 via a board 7.

[0003] In such a seating type floating dock device, it is possible to pour the water into a ballast tank (not shown) of the floating dock 1, sink the dock 1 to the seabed, draw the ship 6 into the floating dock 1, and install it on the board 7. it can.

[0004] Thereafter, the dock 1 can float on the water surface 4 by draining the ballast tank of the floating dock 1. Then, in order to place the side protrusion 2 with the floating dock 1 on the seating base 3, the floating dock 1 is slid in the longitudinal direction, and then water is re-injected into the ballast tank of the floating dock 1. The side protrusion 2 is placed on the upper support surface of the seating table 3. In addition, floating ship 6
In the case of departure from, the operation is performed in a procedure reverse to the above procedure.

[0005]

By the way, in the conventional seating type floating dock device as described above, when the weight of the ship 6 is increased, even if the buoyancy of the floating dock 1 is to be ensured, the floating dock at low tide. 1 cannot be lifted sufficiently, so that the floating dock 1 cannot be seated on the upper support surface of the seating base 3. Therefore, the present invention
An object of the present invention is to provide a seating type floating dock device which can accurately seat a floating dock on a seating table without being affected by ebb and flow of the tide.

[0006]

In order to solve the above-mentioned problems, a seating type floating dock device according to the present invention comprises a large number of seating stands erected in two rows on the seabed, and an upper supporting surface of the seating stand. A floating dock capable of engaging and disengaging the side protrusions and seating thereon is provided, and a surrounding wall standing on the sea floor so as to surround the plurality of seating tables allows a ship to enter the floating dock. And a water pouring / draining means capable of adjusting the water level in the surrounding wall is provided.

In the above-mentioned seating type floating dock device of the present invention, a large number of seating stands erected in two rows on the seabed to seat the floating dock are surrounded by the surrounding wall standing on the seabed together with the floating dock. Since the water level in the enclosed wall is adjusted to an appropriate water level by the pouring / draining means, floating of the floating dock in the enclosed wall by ballast drainage can be performed even when the tide level outside the enclosed wall is low. Even when the weight of the ship installed in the floating dock is large, the boat dock is always properly operated, and thereby the floating dock is properly seated on the seating table.

When the ship in the floating dock is to be evacuated, the water level in the surrounding wall is set to the same level as the external water level while the floating dock is seated on the seabed, and then the sluice of the surrounding wall is removed. And the ship can be evacuated smoothly through the lock.

[0009]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a seat-type floating dock device according to an embodiment of the present invention, and FIG.

Also in the case of the seating type floating dock device of the present embodiment, as shown in FIGS. 1 and 2, a large number of seating stands 3 erected in two rows on the seabed 5, and an upper support for the seating stand 3. Floating dock 1 that can be seated with side projections 2 removably engaged with the surface
Are provided. And the floating dock 1 has a board 7
The ship 6 is installed via the.

In the present embodiment, an enclosing wall 9 is provided upright on the seabed 5 so as to surround all the seating bases 3, and the enclosing wall 9 allows the ship 6 to enter the floating dock 1. A floodgate 12 is attached. The sluice gate 12 has a structure in which the sluice gate 12 is vertically attached and detached by a crane hook 13.

In order to adjust the water level of the water surface 8 inside the surrounding wall 9, a part of the surrounding wall 9 is provided with a pumping pipe 10 as a water injection means and a pumping pipe 11 as a drainage means. .

[0013] In the seating type floating dock device of the present embodiment configured as described above, water is poured into a ballast tank (not shown) of the floating dock 1 to sink the dock 1 to the seabed 5 and the ship 6 to the floating dock 1. It can be retracted and installed on a board 7.

In the present embodiment, in particular, a large number of seats 3 erected in two rows on the seabed to seat the floating dock 1 are provided together with the floating dock 1 on the surrounding wall 9 standing on the seabed 5.
The water surface 8 in the surrounding wall 9 is filled with
Is adjusted to an appropriate water level by
The floating dock 1 is always properly floated by the ballast drainage in the surrounding wall 9 even when the tide level is low outside the surrounding wall 9 or when the weight of the ship 6 installed in the floating dock 1 is large. Will be
Thus, the floating dock 1 can be properly seated on the seating base 3.

In this manner, according to the seating type floating dock device of the present embodiment, the floating dock 1 can be seated (including a sliding operation) without being affected by a tide level change as a natural fluctuation. Therefore, the work in and out of the ship is not restricted by the time, and the work efficiency is improved.

Further, even if the weight of the ship 6 increases, the water level 8 in the enclosure 9 can be raised and lowered above the natural tide level,
As a result, the docking ability of the ship can be increased. Further, the boat 6 can be installed in the floating dock 1 in a state where the floating dock 1 itself does not contact the actual sea surface 4, and the influence of waves can be avoided. Therefore, the efficiency of the approaching / leaving work of the boat 6 with respect to the floating dock 1 is improved.

[0017]

As described above, according to the seating type floating dock of the present invention, the following effects can be obtained. (1) Floating docks can be seated (including sliding work) without being affected by tide changes due to natural fluctuations. Therefore, the entering / exiting work of the ship does not have to be restricted by the time, and the work efficiency is improved. (2) Even if the weight of the vessel increases, the water level in the enclosure can rise and fall above the natural tide level, thereby increasing the docking ability of the vessel. (3) The ship can be installed in the floating dock without the floating dock itself being in contact with the actual sea surface, and the effects of waves can be avoided. Therefore, the efficiency of the approaching / leaving work for the floating dock of the ship is improved.
