Abstract

PURPOSE:To obtain a mass production type buoying body that can commonly be applied to a number of types of buoys by overlapping a number of relatively large-scale synthetic resin annular buoying bodies to comprise a buoyance body. CONSTITUTION:Buoying bodies 12 and 13 are comprised by forming an outside section 14 with easy to mold synthetic resin, such as polyethylene and filling the inside with closed-cell foam type foaming resin with resistance to compression, such as polyurethane foam. One of the buoying bodies is the annular buoying body 12 and the other is the trapezoidal conical buoying body 13. The respective upper and lower surfaces have uneven configuration 16. A buoyance body is manufactured by combining the buoying bodies 12 and 13 appropriately depending upon the structure and size of various types of buoys for mooring and buoyage and alowing a spar buoy 4 to penetrate through the center of the buoying bodies. As a result, the various types of buoys can be put in mass production.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in buoys used as navigational markers, boundary markers for aquaculture areas, mooring buoys, and the like.

Floating buoys used as navigational aids and border markers for aquaculture areas have traditionally been made of metal or plastic and are generally shaped like a single cylinder or disk with the required buoyancy. It was used in

In addition, there are various types of buoys depending on the purpose of use, such as marker light buoys, mooring buoys, and retractable mooring type light buoys, each of which has its own unique floating body, and these can be composed of a common floating body. That was completely unthinkable.

Therefore, there are many types of buoys, and they are often manufactured individually, which has the disadvantage that the manufacturing cost is relatively high.

The present invention has invented a floating body constructed by stacking a plurality of relatively large annular floating bodies made of synthetic resin to form a buoyant body, and has developed a buoy structure in which this floating body is applied to various buoys.

The result is a mass-produced annular floating body that can be commonly applied to many types of buoys, and the number of annular floating bodies can be easily adapted to the buoyancy requirements of the buoy, making the production cost extremely economical. It provides a buoy.

The contents will be described in detail below according to the embodiments shown in the attached drawings.

FIG. 1(a) shows an example of a floating light buoy using a floating body according to the present invention.

The light buoy of this example has a turret (2) with a light fixture (1) on the top and a flange (3) that is erected on the top surface.The cylindrical signboard (6) is inserted through the center of the bottom surface of the flange (3), and the fixture (7) is used to attach the tower (2) to the cylindrical signboard (6). It is constructed by clamping and fixing a floating body (5) between a metal fitting and a flange (3).

In the above, the packing (9) is inserted between the flange (3) and the floating body (5).

In addition, a mooring ring (10) provided on the lower end surface of the specimen (4)
It is moored to a sinker (not shown) on the seabed by a mooring cable (11) connected to the mooring line (11).

The floating body (5) used for the light buoy shown in this example is made by stacking flat cylindrical annular floating bodies (12 x 12') and placing a trapezoidal conical annular floating body (13) underneath with its large diameter part facing upward. They are constructed by overlapping each other.

Both annular floating bodies (12X17X13) have outer shells (14
) is made of an easily moldable synthetic resin such as polyethylene, and the inside is filled with compression-resistant closed-cell foamed resin (15) such as polyurethane foam.

Moreover, a plurality of grooves (16 in the illustrated example) are provided on the upper surface of the flat cylindrical annular floating body (12×17).

(See Figure 1 (b)) The grooves (16) may be concentric circles, radial grooves spaced at appropriate angular intervals, intermittent grooves, or a combination of these various grooves. .

The lower surface of the flat cylindrical annular floating body (12) (1z) is provided with a convex strip (17) having the same shape as the concave strip (16) on the upper surface.

Further, on the surface of the trapezoidal conical annular floating body (13) that is in contact with the flat cylindrical annular floating body (1z), a concave line (16') of the same shape that fits into the convex line (17) of the annular floating body (1z) is provided. is provided.

This eliminates the possibility that when the annular floating bodies are piled up, the respective grooves and protrusions will fit together and misalignment between the annular floating bodies will occur.

The floating body (5) is connected to 7 lunges (3
) and the fixing fittings (7), and each annular floating body making up the floating body (G) is constantly subjected to upward force due to buoyancy, so the concave and convex lines are tightly fitted. There is no fear of misalignment such as rotational misalignment.

The floating light buoy of the present invention is constructed as described above.

Since it is attached to the specimen (4) at the same time, assembly can be carried out at the site as well. Moreover, since the floating body (5) is composed of several annular floating bodies, it is also possible to adjust the buoyancy.

That is, if a large buoyancy is required, the number of annular floating bodies may be increased, and if a small buoyancy is required, the number of four annular bodies may be reduced.

The size of the buoyant force is determined by the conditions of the sea area where the buoy is installed, that is, the tidal current, and each time a buoy is required, the light buoy including the floating body had to be newly designed and created. This can be done by adjusting the number.

In addition, if a floating body is damaged due to a collision with a ship, etc., conventionally the buoy must be replaced, or at least the entire floating body must be replaced, but with the structure of the present invention, damage can be avoided. It can be repaired by replacing only the part of the annular floating body.

FIG. 2 shows an example in which the present invention is applied to a retractable mooring type light buoy, and the floating body is the same annular floating body as the floating type light buoy shown in the example of FIG.

The retractable mooring type light buoy is equipped with a pole retaining ring (1
α), and the sinking weight (19
) It is a stable light buoy with no departure distance and is moored inward.

In the case of this example, two flat cylindrical annular floating bodies (12) are stacked, and trapezoidal conical annular floating bodies (13) (13) are placed above and below them.
The floating body (D) is sandwiched and fixed between the central hole (ef) and flange (c) of the floating body (5') and the fixing fittings (7).

In this case, there are also packings between the flange (3) and the floating body (3) and between the floating body (5') and the fixing fittings (7).
and insert a patch (g).

In this example, it is easy to attach and detach the floating bodies, and as in the example in Figure 1, the required buoyancy can be easily obtained by adjusting the number of combinations of annular floating bodies, so it can be applied to different water depths. Since the damaged annular floating body can also be replaced easily, the same effect as the example in FIG. 1 can be obtained.

Figure 3 shows an example in which the present invention is applied to a mooring buoy.
This is the same as the floating light buoy shown in the illustration.

In this case, a hollow column (2
0) is inserted into the center hole (e/') of a floating body (5'') and made to float.

There are gaskets (cf'
) is inserted.

In the case of this example, the mooring fitting (23) has a mooring ring (21) and a suspension ring (22) on the upper surface of the flange (3#), and a mooring ring (1α') for mooring the buoy on the lower surface. ) is fixed.

(See Figure 3 (a)) In the above, the mooring ring (10') for mooring the buoy may be provided at the lower end of the hollow outer body (20) as shown in Figure 3 (b). .

When the mooring ring (1'') for mooring the buoy is provided on the lower surface of the mooring fitting (23) (example (-) in Figure 3), 1. Hollow column body (2o)
A protective ring (24) is attached to the inner periphery of the lower end.

The floating body (5') in this example was constructed by arranging a trapezoidal conical annular floating body (13') in the upper layer and arranging flat cylindrical annular floating bodies (12XIZ) in the middle and lower layers.

The size of mooring buoys varies depending on the size of the ship to be moored, but in this case as well, by appropriately selecting the number of combinations of annular floating bodies, it is possible to easily obtain a buoy of the required size. can be done.

As described above, according to the present invention, the same annular floating body can be applied to different types of buoys, such as floating 7-type light buoys, retractable mooring type light buoys → mooring buoys, etc. It can be adapted to the number of

For this reason, floating bodies have become increasingly standardized and mass-produced, making them extremely economical.

In addition, the annular floating body is easy to mold and the outer skin is made of inexpensive synthetic resin, so it is easy to mass produce, and it is highly productive, economical, and
A floating body with excellent handling properties can be provided.

Furthermore, if a floating body is damaged due to a collision with a ship or the like, conventionally the entire floating body would often have to be replaced, but according to the present invention, only the damaged part of the annular floating body needs to be replaced. From this point of view as well, it is highly economical and provides excellent maintenance benefits.
