Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention makes it easy to install a buoy, such as a light buoy, which is installed in a waterway such as a sea or a river and regulates the passage of ships, when it is submerged due to a ship collision, typhoon, or the like. The present invention relates to a sign buoy device for submerged buoys, which enables recovery.

[0002]

2. Description of the Related Art Conventionally, when a ship or the like is submerged in water, it is known that the position of the ship is displayed by a buoy.
There are inventions described in No. 21827 or Japanese Utility Model Publication No. 45-28440.

These materials are formed by holding a necessary amount of buoyancy on a buoy before it is submerged in water. for that reason,
The inside of the buoy is always filled with air to obtain the required buoyancy, or is formed of a material with strong buoyancy such as Styrofoam.

[0004]

However, in the case where the buoyancy is previously held in the buoy as described above, the buoy must be large in order to obtain the buoyancy. If the subject to which this buoy is attached is a large one such as a ship, no problem will occur, but it cannot be installed in a small device such as a light buoy and cannot be used.

Since buoys such as light buoys are generally installed at positions where traffic of ships is heavy, a submergence accident due to a collision of ships is likely to occur, and damage caused by submersion of these buoys is economical. Was also very large.

The present invention is intended to solve the above problems, and when installed in a light buoy or the like, it is installed in a small size so that the installation cannot be identified from the outside in a normal state. When a submergence accident or the like occurs, sufficient buoyancy is generated, the sign buoy and the buoy are connected by a connecting cable, and the sign buoy is floated on the water surface, so that the light buoy can be easily collected. To do so.

[0007]

In order to solve the above-mentioned problems, the present invention folds and stores a marker buoy formed by an inflatable air bag in a storage chamber inside the buoy. And connecting the charging device to the indicator buoy that automatically operates by submersion in water,
Form a thin shearing part on the lid of the storage room of this sign buoy,
When the marker buoy is expanded, the lid is sheared from the shearing portion by the expansion pressure to open it, and the marker buoy can be released into water.

Further, the storage chamber may be formed in a head mounted on the upper end of the buoy.

Further, a radar reflecting cloth or a light reflecting tape may be fixed to the surface of the sign buoy.

[0010]

Since the present invention is configured as described above, in a normal installation state of the buoy that does not cause submersion in water,
The sign buoy is stored inside the head mark formed at the top of the buoy,
The installation status cannot be confirmed from the outside. Then, when a ship or the like collides with the buoy and the buoy is submerged, the head mark installed at the upper end of the buoy is also submerged together with the entire buoy.

When seawater, freshwater, etc., invade the inside of the head due to this submersion, the automatic inflator operates in accordance with the intrusion of seawater, freshwater, etc. To fill. When the sign buoy is filled with the pressurized gas, the sign buoy instantly starts expanding in the storage chamber, and the expansion force is applied to the inner surface of the lid of the storage chamber.

The lid has its outer peripheral edge fixed to the head, and a shearing portion, part of which is thin, is formed inside the fixing portion to the head. Therefore, when the lid body is pressed outward due to the expansion of the marker buoy, shear stress concentrates on this shearing portion, the lid body is broken and removed, and the marker buoy is released from the storage chamber to the outside. Will be released.

Due to this discharge, when the marker buoy expands in water, buoyancy is generated, and the marker buoy floats and projects on the surface of seawater or fresh water. Since the marker buoy and the buoy are connected by a connecting cable, the marker buoy is collected to search the buoy, and the connecting cable can be traced to easily collect the buoy. .

The storage room for storing the sign buoy is
Although it is not always necessary to form the head inside the head mounted on the upper end of the buoy, it is convenient to use the head inside the head as a place that is relatively unaffected by waves during normal use of the buoy. Also, by attaching a radar reflecting cloth, a light reflecting tape, etc. to the surface of the sign buoy, the search activity can be facilitated and it will be effective for collecting the buoy.

The head (1) is a storage chamber having a water inlet (3) inside, as shown in FIG. 2, on the outer circumference and bottom.
(4) is arranged. The storage chamber (4) has a flange (5) provided on the outer periphery thereof fixed to the head (1) by a bolt (7) via a packing (6). Also, the opening of the storage room (4)
(8) is covered with a lid (10).

The lid body (10) is made of a material having a certain strength and water resistance such as FRP resin, and the flange portion (11) provided on the outer peripheral edge of the lid body (10) is housed through a packing (12). It is fixed to the head (1) together with the chamber (4) by bolts (7). The lid 10 has a thin shearing portion 13 formed on the inner periphery of the fixed flange 11 as shown in FIG.

The shearing portion (13) is formed on the inner circumference of the flange portion (11) at an acute angle, and when a pressing force is applied to the lid body (10) from the storage chamber (4) side, shear stress is generated. It is formed so as to concentrate and break from the sheared portion (13) so that the lid body (10) can be separated. In addition, the marker buoy (14) and the head marker (1) that constitutes the buoy are connected by the connecting cable (31).
As shown in FIG. 3, the sign buoy (14) is folded and stored in the storage chamber (4). This sign buoy (14) is a rubberized cloth,
The inflatable air bag is made of soft resin, rubber or the like. The sign buoy (14) is connected to a refueling device (15) that automatically operates to fill air when submerged in water, so that the sign buoy (14) can be automatically expanded when submerged in water. .

In this embodiment, three charging and charging devices (15) are connected and stored in the storage chamber (4) at approximately the center of the folded and stored marker buoy (14). There is. The charging device (15) may have any structure as long as it can be automatically charged by submerging in water.

This spool magazine (25) has an engagement step portion.
It is fixedly inserted between (27) and lever (22).
It abuts against a fixed wall (28) provided between the (22) and the engagement step (27). Further, the pool magazine (25) has a strong strength at all times when it is dry, but when the water enters the head (1) and comes into contact with the water due to the submersion of the buoy, it easily dissolves, It is made of a material that cannot retain its shape. For example, pulp, sugar, gypsum and the like can be used.

When it dissolves in water and its shape collapses, the conductive shaft (24) presses the lever as shown by the chain double-dashed line in FIG. The lever (22) is rotated as a fulcrum. By this rotation, the lever strikes the firing pin (21), and the cylinder (17)
Since it pierces the sealing plate (20), the pressurized gas obtained by vaporizing the liquefied gas is ejected from the cylinder (17). This gushing gas,
It is introduced into the marker buoy (14) from the outlet (30) through a non-circulation valve (not shown) or the like.

In the structure as described above, when the buoy or the like is placed in the sea, in a waterway or the like under normal use, the marker buoy (14) is inside the head marker (1). It remains stored in. And a ship collides with the buoy,
