JPS63284093A - Tube float type lighting sign buoy with seawater moving in and out of float - Google Patents

Abstract

PURPOSE:To simplify the construction of a buoy and to improve its durability, by housing tubes, which are inflated by the internal pressure, in a disc-shaped float, with seawater moving in and out, while filling the float in its hollow space with foaming styrene pieces and mounting a sand weight to the bottom part and a lamp to the upper part. CONSTITUTION:A float is constituted of upper and bottom part float panels 1, 2 vertically divided in the central part being formed both by a molded article of fiber reinforced plastic (FRP), and three rubber made annular tubes 3 of mutually different sectional diameter are housed inside the float. And the space between these tubes 3 and the float is charged with a foaming styrene fine piece 5. The bottom part float panel 2 forms its bottom surface into a section of cone shape further a cylindrical part in the center being protruded to the bottom, and a sand weight 6 is housed in this cylindrical part. While the upper part float panel 1 provides an electric chamber 7 through a base housing a battery or the like in this electric chamber 7. And a desired sign buoy is constituted vertically providing a lamp 9 in the upper part of this electric chamber 7 through a pole 8.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is an illuminated marker buoy that is installed in deep sea or shallow sea and can be used for various signs, and is particularly characterized by having a tube floating body that enters and exits seawater.

BACKGROUND TECHNOLOGY AND PROBLEMS Conventional floating illuminated sign buoys are generally completely sealed and have the problem of losing their buoy function, as entering seawater is considered fatal.

Means for Solving the Problems The present invention has the following configuration as a means for solving the above-mentioned problems.

(1) A tube expanded by internal pressure is housed in a disc-shaped floating body through which seawater enters and exits, and the space is filled with small pieces of Styrofoam, etc. A sand weight is attached to the bottom, and a light is attached to the top through an air chamber. Installed it.

(2) A disc-shaped floating body is composed of a lower floating body panel and a lower floating body panel that are divided into upper and lower parts at the center, and the bottom surface of the lower floating body panel has a cross-sectional shape with a cylindrical part protruding from the center. A sand weight is housed in the cylindrical part.

(3) The tube expanded by the internal pressure is a rubber tube having one or more independent annular shapes and has an internal pressure of approximately 5 atmospheres.

B) Various long and short balls are interposed between the electrical room and the lamp.

■ The disc-shaped floating body consists of an upper floating body panel and a lower floating body panel, which are divided at the upper part. It accommodates a stand-up tube.

Function The tube floating body of the present invention has a large number of honeycomb-like holes on the outside to allow seawater to enter and exit the floating body, so it does not sink due to the intrusion of seawater and can be easily disassembled for adjustment and cleaning. The tube floating body is an annular rubber tube with an air pressure of about 5 atmospheres, and it has the highest buoyancy and can withstand seawater corrosion.
In addition, the tube is protected by small pieces of foamed polystyrene filled in the space between the tube and the floating body. The sand weight is a nylon bag containing an appropriate amount of sand, which is easily available at the beach, to balance the floating body. The floating body has a shape that is highly reliable in deep and shallow waters, and is especially suitable for shallow waters by incorporating an unparalleled bottom with a depth of 50 cm.
It can be installed even in the shallowest seas. Furthermore, the floating body of the present invention has a rounded shape so that it does not damage fishing nets and fishing gear, and because it contains air, it is light and easy to transport at a slow pace.

Embodiment FIGS. 1(A) and 1(B) are for open sea use, and the floating body is divided at the center and consists of an upper floating body panel 1 and a lower floating body panel 2, both of which are molded products of FRP. 3 is a rubber tube, and there are three annular tubes: an outer tube, a middle tube, and an inner tube. 4 is each air inlet.

The space between the floating body and the tube 3 is filled with styrofoam strips 5. The bottom surface of the lower floating body panel 2 has a square cross-section, and a cylindrical part protrudes from the center, and a sand mold 6 is accommodated in the cylindrical part. The sand weight 6 is a nylon bag filled with sand. An electrical chamber 7 is provided in the upper floating panel 1 via the base, and accommodates batteries, air batteries, dry cells, storage batteries, and the like. 8 is a ball, and 9 is a lamp. In the above configuration, if the amount of air in the tube 3 is insufficient, the necessary amount is reinforced by the bicycle's air pump using the Kelep air injection container in the air inlet 4 provided on the upper part of the floating body. It is also possible to take out the tube 3 and repair it using the same method.

To insert or remove the sand weight 6, remove the 6 nuts from the upper ball attachment port and the floating body to insert it into the cylinder, or put your hand inside the cylinder and take it out.

Figures 2 (A) and (B) are for inland seas, and differ from Figure 1 only in that there are three or two tubes.

3(A) and 3(B) are for use in a bay, and the only difference is that they use only one tube instead of three.

Figures 4 (A,) and (B) are modified examples for use in inland waters, in which the floating body is divided at the upper part, and inside the lower floating body panel 2 there is a small annular stand inside the annular flat tube 3. Place tube 3
The bottom surface is flat and a sand weight 6 is attached below.

Effects of the invention (1) Since the floating body moves in and out of seawater, there is no need to worry about malfunctions due to intrusion of seawater.

(2) Rubber tubes are safe because they are resistant to seawater corrosion and are protected by a filling such as styrofoam, and the internal pressure can be easily replenished.

■Lightweight and easy to transport and handle.

■ Simple structure and can be manufactured at low cost.
