Abstract

(57) [Summary] [PROBLEMS] To stably float on the surface of water with a simple configuration, reduce the overall weight, and handle easily.
Furthermore, a buoy having a structure that can be manufactured at low cost is provided. SOLUTION: A buoy 1 generally has a floating body 11 and a water tank 12 provided with openings 13 and 14 communicating the inside and the outside.
And When transporting the buoy 1 to the water area where the buoy 1 is to be installed, the water tank 12 is empty and can be easily handled. The water tank 12 is filled from the opening 13 and functions as a weight, so that the water tank 12 floats stably, and the shaking due to waves and the like is attenuated. Also,
In the case of moving the buoy 1, the water is discharged from the lower opening 13 simply by lifting the buoy 1 above the water surface WL.
The water tank 12 is surely light in weight, easy to handle, and convenient to carry.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a buoy, and more particularly to a buoy used for stably supporting a light pole having an indicator light on the water surface and mooring it in a fishnet, aquaculture facilities, and the like.

[0002]

[Prior art]

 In order to stably float the buoy above the water surface, conventionally, a weight made of metal or the like is generally provided so as to be positioned below the water surface.

[0003]

[Problems to be solved by the invention]

 However, as described above, a buoy provided with a weight made of metal or the like increases the overall weight, and is inconvenient to handle when transporting to the installation location or moving the installation location. There was a problem. In addition, in the buoy described above, there is a problem that the manufacturing cost is increased due to the provision of the weight made of metal or the like.

The present invention has been made in view of the above-mentioned problem, and has a simple structure, stably floats on the water surface, and can be easily handled by reducing the overall weight. It is an object of the present invention to provide a buoy having a structure that can be manufactured at low cost.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the buoy of the present invention is characterized by comprising a floating body, and a water tank provided below the floating body and provided with an opening communicating between the inside and the outside. .

In the present invention, a water tank is provided below the floating body, and when the buoy is installed, the water in the installation water area is filled into the water tank from the opening. As a result, the water tank functions as a weight, which stabilizes the buoy in balance with the buoyancy of the upper floating body. When the installation location is moved, drain the water from the water tank through the opening by lifting the water tank above the water surface. Since the water tank is empty, handling such as transportation is easy.

[0007]

[Embodiment of the invention]

 One embodiment of the buoy of the present invention will be described with reference to the drawings. In the drawings, the same reference numerals denote the same or corresponding parts. The buoy 1 according to this embodiment generally includes a floating body 11 and a water tank 12 provided below the floating body 11 and provided with openings 13 and 14 for communicating the inside and the outside.

In the case of the present embodiment, the floating body 11 is formed such that the inside thereof is formed in a substantially disk shape having a hollow space. The volume and diameter are set accordingly. It is desirable that the diameter (the size in the horizontal direction) of the floating body 11 is larger than the water tank 12 in order to stabilize the buoy 1. In the embodiment shown in FIG. 1, a flange 11a for mounting the hollow light pole 5 in an airtight and watertight state is formed above the floating body 11. An index lamp 5a such as an LED lamp and a so-called solar cell 5b are provided at the upper end of the light pole 5, and the power generated by the solar cell is stored below the floating body 11 as necessary. A portion 11b for accommodating a battery having a relatively high specific gravity, such as a battery (not shown) for supplying power to the LED lighting device, is provided so as to protrude into the water tank 12. Further, the floating body 11 is provided with a connecting portion 11c for connecting a mooring rope (not shown) or the like.

The water tank 12 is arranged below the floating body 11 and is set to have a predetermined volume in consideration of a relative balance with the floating body 11 that supports the light pole 5 and the like. Openings 13 and 14 are provided below and above the water tank 12 so as to face in the same direction. The lower opening 13 functions as a water passage for introducing surrounding water into the buoy when the buoy is installed, and the upper opening 14 allows water to flow from the lower opening 13. When introduced, it functions as a vent for discharging air from the water tank 12. In addition, the opening 13 functioning as a water supply port is not limited to the lower side of the side surface of the water tank 12, but may be provided on the bottom surface 12a.

[0010] In order to manufacture a buoy having such a configuration, the floating body 11 and the water tank 12 may be integrally formed as shown in the figure, or may be separately formed so that they are mutually separated. It is good also as a structure joined to. Further, the floating body 11 and the water tank 12 can be formed of resin, FRP, or a metal such as aluminum.

When the buoy 1 configured as described above is transported to a water area in which it is to be installed, the buoy 1 can be easily handled because the water tank 12 as well as the floating body 11 is empty. Upon installation, the water in the installation area is filled into the water tank 12 through the lower opening 13 by launching. At this time, since the air in the water tank 12 is discharged from the upper opening 14, the water is reliably filled in the water tank 12 in a short time and floats stably. Even if the buoy 1 shakes due to waves or the like, since the water filled in the water tank 12 functions as a weight, the buoy 1 does not overturn, and the shaking is attenuated. Since the lower opening 13 and the upper opening 14 are formed in the same direction, the water filled in the water tank 12 flows out even when inclined due to waves or the like. There is no.

In addition, the buoy 1 of the present invention, when moving or collecting the installation water area, simply lifts it above the water surface WL, and air is introduced into the water tank 12 from the upper opening 14. Since the water is discharged from the lower opening 13, the water tank 12 is lightened with certainty in a short time, and the handling is easy and the transportation is convenient. Since the buoy 1 of the present invention has a very simple structure, it can be manufactured easily and at low cost.

[0013]

[Effects of the Invention] According to the present invention, a simple structure including a floating body and a water tank provided below the floating body and having an opening communicating between the inside and the outside is provided, and the water surface is stably provided. It is possible to provide a buoy having a structure that can be levitated, can be easily handled with a reduced overall weight, and can be manufactured at low cost.
