Description

[Detailed explanation of the idea] This invention relates to a scuttling device for floating bodies.

If the mooring device of a floating body floating on the sea surface is damaged, the floating body may drift and cause damage to coastal facilities.

The purpose of this invention is to provide a scuttling device that automatically opens the bottom cover when a floating body begins to drift, allowing water to enter the floating body, and sinking the floating body without requiring power such as electricity. There is a particular thing.

The floating body scuttling device based on this invention consists of an opening made in the bottom of the hollow floating body, a gasket made all around the outside of the opening, and a gasket from the outside that is anchored to the bottom of the water by a connecting cable and seals the opening. a bottom cover that presses against the bottom cover, and at least two parts, the lower part of which is pivotally connected to the lower part of the floating body on the outside of the opening side.
It consists of a bottom cover holding member, a spring added between the bottom cover and the bottom cover holding member to press the bottom cover against the packing, and an air vent provided on the upper wall of the floating body. Attachment parts are formed below both sides of the bottom cover to protrude almost parallel to the bottom cover and hold the spring between the bottom cover, and the upper part of the bottom cover holding member is attached from both outside sides of the bottom cover in pressure contact with the packing. The bottom of the floating body that protrudes toward the center of the bottom cover almost parallel to the spring attachment part and is pressed by the spring against both outer edges of the bottom cover that are in pressure contact with the packing and is pulled by the connecting cable. A bottom lid holding portion is formed that can enter into the gap with the lid.

This invention will be described below with reference to embodiments shown in the drawings. As shown in FIG. 1, a hollow floating body 10 is connected to a mooring line 12, and a portion of the floating body 10 protrudes above the sea surface.

The scuttling device 20 has an opening 21 made in the bottom of the floating body 10.
, a packing 22 provided around the entire outer circumference of the opening 21, a bottom cover 23 that is anchored to the seabed by a connecting cable 24 and pressed against the packing 22 from the outside so as to seal the opening 21, and a bottom cover 23 provided on both outer sides of the opening 21. two bottom lid holding members 26 whose lower parts are pivotally attached to the lower portion of the floating body 10; a spring 28 that is attached between the bottom lid 23 and the bottom lid holding member 260 to press the bottom lid 23 against the packing 22; It consists of an air vent 29 provided on the upper wall of the floating body 10.

One end of the connecting cable 24 is connected to the bottom cover 23, and the other end is connected to a weight 25 sunk in the seabed.

The bottom cover holding member 26 has a substantially C-shape and is pivotally connected to the bracket 11 provided at the bottom of the floating body 10 by a pin 27.

At the lower part of the bottom cover holding member 26, a spring application part 26a is formed which projects from the pin 27 portion to the lower blades on both sides of the bottom cover 23, substantially parallel to the bottom cover 23, and the spring application part 26a and the bottom cover 23
A spring 28 is held between.

At the top of the bottom cover holding member 26, there is a bottom cover holding part 26c that protrudes from the circumferential outer side of the bottom cover 23 in pressure contact with the packing 22 toward the center of the bottom cover 23 almost parallel to the spring retaining part 26a.
is formed.

Then, the bottom cover holding part is held by the gasket 22 by the spring 2B.
Its end surfaces 26b are pressed against both outer edges of the bottom cover 23 that are in pressure contact with the bottom cover 23, and the floating body 10 is made to be able to enter the gap between the bottom of the floating body 10 and the bottom cover 23 that is created when the connecting cable 24 is pulled. .

Next, the operation of the scuttling device 20 of this embodiment will be explained.

During storage, as shown in FIG. 2, the bottom lid 23 is brought into close contact with the gasket 22, and the end surfaces 26b of the bottom lid holding portion of the bottom lid holding member 26 are pressed against both outer edges of the bottom lid 23.

The bottom cover holding members 26 on both sides are pushed by the springs 2B and the bottom cover holding parts 26c try to rotate in the direction of approaching each other.
Both bottom lid holder end surfaces 26b are pressed against both outer edges of the bottom lid 23 and fixed in that position.

Therefore, the bottom cover 23 is pushed upward by the spring 28,
The water pressure is added to this, and the opening 21 is completely sealed, so there is no risk of water entering from there.

When the mooring line 12 is cut, the floating body 10 begins to drift, and when the floating body 10 moves a predetermined distance from the mooring position, tension is generated in the connecting line 24.

When the pressure exerted by the tension spring 28 exceeds the sum of the force and the water pressure, the bottom cover 23 separates from the gasket 22, creating a gap, through which water begins to enter the floating body 10.

At this time, the air within the floating body 10 is exhausted from the air vent 29.

When the tension further increases, the gap between the bottom cover 23 and the bottom becomes larger, and the end face 26b of the bottom cover holding part of the bottom cover holding member 26 comes off the outer edge of the bottom cover 23, and the bottom cover holding part 26c is separated from the bottom cover 23 and the bottom. Enter the gap.

Since the bottom cover holding member 26 is pushed by the spring 2B in the direction in which the bottom cover holding part 26c further enters the gap, once the bottom cover holding part 26c fits into the gap, the tension on the connecting cable 24 is small after it is flattened. Even if this happens, the bottom cover 23 remains open.

Therefore, further water intrudes and eventually the floating body 10 sinks.

Since the scuttling device according to this invention has the above-mentioned configuration,
When moored, the bottom cover 2 is held by the bottom cover holding member 26 and the spring 26.
3 is pressed against the packing 22 to keep the opening 21 in a sealed state to enable mooring, and when the mooring line is cut and the floating body 10 begins to drift, tension is generated in the connecting line 24 and the bottom cover 23
A gap is created between the bottom cover 23 and the gasket 22, and furthermore, the bottom cover holding part 26c of the bottom cover holding member 26 fits between the bottom cover 23 and the bottom of the floating body 10 to maintain the open state, and the air inside the floating body 10 is Since water is discharged from the air vent 29, water can enter the floating body 10 and cause it to sink.

Furthermore, power such as electric power is not required for this purpose.
