Description

Detailed Description of the Invention

[0001]

[Industrial field of use] This is a device that facilitates the search for a light buoy when a traffic light buoy sank due to an accident.

[0002]

2. Description of the Related Art Since a traffic light buoy is installed in a place where traffic of ships is heavy, it often sinks due to a collision of ships. In that case, the position of the sinker is rarely left as it is, and in many cases, the sinker and the sinker are brought to a considerably distant position due to the impact of a collision. If the sinking weight does not move after sinking, the sinking weight's position can be searched easily because it is easy to find it in the record at the time of marking, and it can be searched for within the length of the mooring line. If it happens, the search is quite difficult. A boat equipped with a sounding instrument and a fish finder travels vertically and horizontally around the installation site to dive into a diver and search, but this requires a lot of time and labor. In addition, when the mooring line was cut, the sinker was also moving, and the sinking position of the buoy was further moving, which made the search more difficult.

[0003]

If the search for these sunk light buoys takes a long time, they may be caught by a bottom dragnet or the like, causing damage such as damage to the net. In order to solve these problems, the present invention uses a top mark that a traffic sign light buoy has for marking a route as a floating body, and when the light buoy sinks, a floating body (top mark) that automatically becomes a mark. ) Is a sinking light buoy search assisting device that is detached and floats on the surface of the sea.

[0004]

In order to achieve this object, in the present invention, a top mark is formed on a buoyant body, a drum around which a connecting cable is wound, and a detaching portion for accommodating and fixing a disconnecting tool which operates at a predetermined water pressure are provided. It is inserted between the top mark and the top of the light buoy, and the joint between the detachment part and the top mark is a fitting joint that can be inserted and removed freely.The connecting cord is connected to the top mark, and the top mark is connected to the disconnecting tool via the tightening tool. Then, the sinking lamp buoy search assisting device is configured such that the tightening tool is tightened to lock the top mark on the lamp buoy top and the separating tool is activated at a predetermined water depth when the sinker sinks so that the top mark floats.

In the above apparatus, the joint between the top mark and the detaching portion is a flange joint, a pin insertion hole is opened in the flange with the top mark, a cable insertion hole is opened in the center of the upper flange with the detaching portion, and the upper surface of the flange is described above. A fitting joint in which a pin is implanted at a position corresponding to the pin fitting hole may be used.

Further, it is preferable that a plurality of columns are fixed between the upper part flange and the lower part flange on the upper surface of which the separating tool is attached, and a drum is attached to the supporting part.

Further, it is preferable to insert a synthetic resin plate between the top mark and the flange joint of the detaching portion to prevent the adhesion due to salt.

[0008]

[Operation] When the light buoy sinks due to a collision such as with a ship, the disconnecting tool operates at a predetermined water depth, the top mark is inserted and the tightening force that was tightened on the joint is released, and the top mark disengages from the joint. Ascending, the connecting line extends from the drum, floats to the surface of the sea, and is easily found. By tracing the connecting line, the sinking buoy can be easily searched.

Further, if the fitting joint is a flange joint, and a flange having a pin fitting hole and a flange in which a pin is implanted are used, fixation by fitting locking and detachment and floating can be surely facilitated.

Further, by constructing the detaching portion in this way, it is light and compact, and can be attached to an existing lamp buoy.

If a synthetic resin plate is inserted between the top mark and the flange joint of the detaching portion, the salt can be easily detached without sticking even if salt is attached due to waves.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an explanatory view showing a process of raising a top mark in the process of sinking of a light buoy embodying the present invention.
In the figure, 1 is a top mark to form a buoyant body, 2 is a detachment part, and 3 is a light buoy, 4 is a mooring line moored to a sinker (not shown) on the seabed, and 21 is a seabed. Is. The light buoy above the surface of the sea is a light buoy that is normally floating, and the light buoy below it indicates that the top mark is floating due to the disconnecting device of the detachment part operating at a predetermined water depth during the sinking process. The buoy is completely submerged and the top mark is above the sea level. Reference numeral 15 is a connecting cable.

FIG. 2 is a partially cut front view of the top mark and the detached portion. The top mark is a head mark attached to the top of the light buoy for marking the route. The appearance is cylindrical, conical, spherical, etc. It is made lightweight, but it is not intended for buoyancy. Since it is also used as a buoyant body in the present invention,
The top mark may be formed with a closed-cell foam resin such as expanded polystyrene or expanded polyurethane resin, and the surface may be coated with a synthetic resin, or may be formed into a watertight hollow shape with a thin metal plate such as an aluminum alloy. Reference numeral 1 denotes a cone-shaped top mark buoyant body of one example of which an outer cover 6 is made of synthetic resin, and a closed cell foam resin 7 is filled inside the outer cover.
Reference numeral 5 is a top mark support, 8 is a flange fixed to the support 5, and 2 is a detachment portion.

FIG. 3 is a partially cut enlarged front view of the detaching portion. 8a is a pin fitting hole opened in the flange 8, 9 is a synthetic resin plate sandwiched between the flanges, 10 is a top flange of the detaching portion, 10a is a positioning pin implanted in the flange 10, 11 is a top of the light buoy. A detachable portion lower flange for attachment of the detachable portion, 12 a column of the detachable portion, 13 a disconnecting tool, 13a a mounting piece, 14 a connecting rope drum, 15 a connecting rope such as a wire, 16 a tightening tool such as a turnbuckle, Reference numeral 17 denotes a ring with a disconnecting tool, which is released when a predetermined water pressure is applied to the disconnecting tool 13. The disconnecting tool may be one that is generally used for inflatable liferafts for ships. 18 is a stop bar for tightening tool.

FIG. 4 is a view taken along line AA of FIG.

FIG. 5 is a partially cut BB view of FIG.
Reference numeral 19 is a shackle, and 20 is a swivel. In the present embodiment, the connecting cord 15 is connected to the shackle 19 via the swivel 20, but it goes without saying that it may be directly connected to the top mark stop bar 18.

[0017]

[Effects of the Invention] When the light buoy is sunk due to a collision of a ship or the like, water pressure is surely applied at a predetermined water pressure position, the disconnecting tool is surely operated, and the tightening force that tightens the top mark is released. The mark detaches and rises and floats on the surface of the sea so that it can be easily found on the sea or in the sky. You can easily search for the sunken buoy by following the connecting lines.

Since the top mark is used as a buoyant body, the device becomes compact, and the device is compact and lightweight, so that it can be easily applied to an existing lamp buoy.
