Description

[Detailed description of the invention] (Field of industrial application) This invention relates to the float structure of an underwater exploration buoy.
In particular, it concerns the float structure of an underwater exploration buoy that has been devised to shorten the scuttling time.

(Prior Art) Conventionally, in this type of float structure, a natural scuttle 6 is attached to the side of the float 2 at a position submerged in water, as shown in FIGS. After a certain period of time has elapsed after the floats 7 come into contact with each other, a hole opens in the natural scuttle 6, through which the gas inside the float escapes, and at the same time, seawater 7 enters the float from outside, causing the underwater exploration buoy to scuttle.

(Problems to be solved by the invention) In the conventional float structure described above, even if a hole opens in the natural scuttle and water enters the float, if the seawater inside the float reaches a position higher than the natural scuttle 6, However, the disadvantage was that the gas inside the float was difficult to escape to the outside of the float, making it difficult for the float to sink.

The purpose of the present invention is to eliminate such drawbacks and provide a float structure for a seawater exploration buoy that quickly scuttles after the natural scuttling device comes into contact with water.

(Means for Solving the Problems) In order to achieve the above-mentioned purpose, the floating structure of the underwater exploration buoy of the present invention has a natural scuttling device 6 disposed at a position where it will be submerged in the water, and will naturally scuttle when it comes into contact with seawater 7. In an underwater exploration buoy that scuttles by opening a hole in the vessel 6 and releasing the gas in the float 2, the natural scuttling vessel 6 is attached to one end of the resilient tube 4 made of a flexible elastic material. The other end is connected to the upper part of the float 2.

(Example) Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention.
Figure a shows the state of use, and figure b shows an enlarged view of the float portion.

As shown in FIGS. 1a and 1b, there is a float 2 on the top of the buoy body 1, and when the buoy lands on the sea, the float 2 is filled with gas and floats due to its buoyancy.

A tube 4 made of rubber as a flexible and elastic material (hereinafter referred to as a rubber tube) 4 is connected to the upper part of the float 2 via a U-shaped tube 3. A natural scuttle 6 is attached to the tip of the rubber tube 4 together with a buoyancy material 5. The shape of the rubber tube 4 has resilience due to its elasticity, and forms a gas escape section together with the scuttling device 6 and the U-shaped tube 3.

When a seawater exploration buoy using this float lands on the sea, the float is expanded and the natural scuttle 6 comes into contact with the seawater 7. In this state, after a certain period of time passes, a hole opens in the natural sinker and the gas inside the float 2 escapes to the outside through the U-shaped tube 3 and the rubber tube 4. Since the buoyancy material 5 is attached to the natural scuttler 6, the gas escape port is always at a shallow place near the sea surface, and the rubber tube 4 maintains a nearly straight shape due to its elasticity, so the gas can pass through without resistance. I can do it. As the gas in the float runs out, the float deflates, loses its buoyancy, and the buoy scuttles.

(Effects of the invention) As explained above, the present invention has the effect that by releasing gas from the upper part of the float, the gas can be reliably released and the buoy body can be scuttled, and the scuttling time can be shortened.
