Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a floating body for a buoy that can be widely applied to various types of buoys used as navigational aids, boundary markers for aquaculture areas, mooring buoys, and the like. Floating buoys used as navigational markers and boundary markers for aquaculture areas have conventionally been made of metal or plastic, and are generally shaped like a single cylinder or disc 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 configured with a common floating body. That was completely unthinkable. Therefore, there were many types of buoys, and they were often produced individually, resulting in relatively high production costs. In the present invention, a floating body is formed by stacking a plurality of relatively large annular floating bodies made of synthetic resin, and a plurality of concentric grooves and protrusions are formed on each contact surface between the annular floating bodies so that they fit into each other. , is a floating body for buoys with a cylindrical column inserted through the center and sandwiched from above and below. 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. A floating body for a buoy is provided. The contents will be described in detail below according to the embodiments shown in the attached drawings. FIG. 1a 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 cylindrical body 4 protruding from the center of the lower surface of a flange 3 which has a turret 2 with a light fixture 1 on its top erected on the upper surface. The floating body 5 is clamped and fixed between the fitting and the flange 3 by a fixing fitting 7 which is inserted through the flange 3 and is detachable. In the above, gaskets 8 are provided between the flange 3 and the floating body 5 and between the floating body 5 and the fixing fitting 7 , respectively.
and the packing 9 is inserted. In addition, a mooring ring 10 provided on the lower end surface of the specimen 4
The vessel is moored to a sinker (not shown) on the seabed by a mooring line 11 connected to the vessel. The floating body 5 used for the light buoy shown in this example is constructed by stacking flat cylindrical annular floating bodies 12, 12' and below them a trapezoidal conical annular floating body 13 with its large diameter portion facing upward. This is what I did. Each of the annular floating bodies 12, 12', and 13 has an outer skin 14 made of easily moldable synthetic resin, such as polyethylene, and an interior filled with compression-resistant closed-cell foamed resin 15, such as polyurethane foam. . Further, a plurality of grooves 16 (three in the illustrated example) are provided on the upper surface of the flat cylindrical annular floating bodies 12, 12'. (See FIG. 1b) A plurality of grooves 16 are provided concentrically. Further, on the lower surface of the flat cylindrical annular floating bodies 12, 12', a convex strip 17 of the same shape corresponding to the concave strip 16 on the upper surface.
is provided. Further, on the surface of the trapezoidal cone-shaped annular floating body 13 that is in contact with the flat cylindrical annular floating body 12', the annular floating body 1
A recessed line 16' of the same shape is provided which fits into the convex line 17 of 2'. This eliminates the possibility that when the annular floating bodies are piled up, the respective grooves and protrusions will fit together, causing misalignment between the annular floating bodies. In addition, by providing concentric grooves and protrusions on the upper and lower surfaces of the annular floating body, the rigidity of each surface is increased, and the flatness of the upper and lower surfaces is improved when manufacturing the annular floating body (when filling the outer skin with foamed resin). It is effective for producing The floating body 5 is clamped and fixed between the flanges 3 and the fixing fittings 7 via the seals 8 and 9, and each annular floating body that makes up the floating body 5 is constantly subjected to an upward force due to buoyancy, so that the concave and convex lines are The fit is tight, and there is no risk of misalignment such as rotational misalignment, and they come together to form a single floating body. The floating body for a buoy of the present invention is constructed as described above. Since the floating body 5 of the present invention is removably attached to the specimen 4 using the fixing fittings 7 (in this example, it is divided into two and removably attached to the specimen 4), assembly can be carried out satisfactorily even on site. Furthermore, 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 annular floating bodies may be decreased. The amount of buoyancy is determined by the conditions of the sea area in which it is installed, namely tidal currents, wave height, and water depth.In the past, whenever a light buoy was required to have the buoyancy necessary for the conditions of the sea area in which it was installed, However, according to the present invention, this can be done by adjusting the number of combinations of annular floating bodies. 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 damaged part of the annular floating body. FIG. 2 shows an example in which the floating body of the present invention is applied to a retractable mooring type light buoy, and the floating body uses the same annular floating body as the floating type light buoy shown in the example of FIG. As shown in the second figure, the retractable mooring type light buoy is equipped with a light fixture 1' at the top of the marker body 18 , a floating body 5' in the middle, and a mooring ring 10' at the lower end, and is attached to a sinker 19 on the seabed by a mooring line 11'. , it is a stable light buoy with no separation distance and is moored in such a way that the water line is above the beacon 18 on the side of the floating body 5' . In this example, two flat cylindrical annular floating bodies 12 are used.
Stacked one on top of the other, trapezoidal conical annular floating bodies 13,
13' to constitute a floating body 5' , a marker column 18 is inserted into the center hole 6' of the floating body 5' , and a flange 3' provided on the marker column 18 and a fixing fitting 7' are used to secure the floating body 5 '. ' is clamped and fixed. In this case as well, a packing 8' and a packing 9' are inserted between the flange 3' and the floating body 5 ' and between the floating body 5' and the fixture 7 ' . In this example as well, it is easy to attach and detach the floating body, and the first
As in the example shown, the required buoyancy can be easily obtained by adjusting the number of combinations of annular floating bodies, so it is easy to deal with different water depths when relocating the buoy, and it also prevents damage. Since the annular floating body can be replaced, the same effect as in the example shown in FIG. 1 can be obtained. FIG. 3 shows an example in which the present invention is applied to a mooring buoy, and the floating body is the same as the floating light buoy shown in FIG. In this case, the hollow column 20 having a flange 3'' at the upper end is inserted into the center hole 6'' of the floating body 5' ', and the fixing fitting 7'' provided on the hollow column 20 is attached to the lower end of the floating body 5'' . 5" is clamped and fixed. Gaskets 8'' and 9'' are inserted between the flange 3'' and the floating body 5'' and between the floating body 5'' and the fixed metal 7'' , respectively. In this example, a mooring fitting 23 having a mooring ring 21 and a hanging ring 22 on the upper surface and a mooring ring 10'' for mooring a buoy on the lower surface is fixed to the flange 3''. (See Figure 3a) In the above, the mooring ring 10'' for buoy mooring is the third
As shown in FIG. b, it may be provided at the lower end of the hollow columnar body 20 . When the mooring ring 10'' for mooring the buoy is provided on the lower surface of the mooring fitting 23 (example a in FIG. 3), a protective ring 24 is attached to the inner periphery of the lower end of the hollow column 20. In this example, the floating body 5'' The mooring buoy has a trapezoidal conical annular floating body 13'' in the upper layer, and flat cylindrical annular floating bodies 12, 12' in the middle and lower layers. Although the size of the floating bodies varies, in this case as well, by appropriately selecting the number of combinations of annular floating bodies,
You can easily get a buoy of the size you need. As described above, the present invention can be widely applied to different types of buoys using the same annular floating body, such as floating light buoys, retractable mooring light buoys, mooring buoys, etc.
Moreover, it can be adapted to any size from small to large by changing the number of annular floating bodies. For this reason, floating bodies have become increasingly standardized and mass-produced, making them extremely economical. In addition, by providing concentric grooves and protrusions that fit into each other on the contact surface of each annular floating body, it is possible to easily overlap the upper and lower annular floating bodies correctly when stacking the annular floating bodies, and then can be assembled quickly. Furthermore, by simply holding the floating body between the upper and lower sides with fixing fittings, it becomes an annular floating body or an integral floating body, making assembly extremely easy. In addition, by making the annular floating body at the upper end, lower end, or both upper and lower ends of the buoy floating body into a trapezoidal conical shape, the resistance of the buoy due to waves, water current, or wave water flow is reduced, respectively.
This has the effect of reducing the inclination and departure of the buoy. Furthermore, since the annular floating body is easy to mold and has an outer skin made of an inexpensive synthetic resin, mass production is easy, and a floating body with excellent productivity, economy, and handling 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 is replaced. It only needs to be replaced, and from this point of view as well, it is highly economical and has excellent effects in terms of maintenance.
