Abstract

PROBLEM TO BE SOLVED: To provide a device for submerging/floating of a submarine, capable of achieving higher safety, more energy saving and more comfortable space by improving a submerging/floating system.SOLUTION: A container 1 and an expandable/contractable film 2 are filled with high-pressure air, and a weight 3 is arranged in the container 1 and the expandable/contractable film 2 filled with the high-pressure air to be bonded and fitted to the bottom part of the expandable/contractable film 2. When the container 1 is in an upper side, the expandable/contractable film 2 has a maximum volume because of the effect of the gravity of the weight 3. When the container 1 is in a lower side, the volume of the expandable/contractable film 2 is minimum similarly because of the effect of the gravity of the weight 3. However, weight is not changed in both states. Thus, by intentionally increasing/decreasing the volume of a part of a submarine, a system may be changed to a submerging/floating system by increasing/decreasing a floating force with respect to the volume.SELECTED DRAWING: Figure 2

Description

  The present invention relates to the development of a device related to the submerged ascent of a submersible craft.

  Conventionally, ballast tanks and air accumulators are the most important devices in a submerged levitation system.

When submerging, put seawater in the ballast tank to increase the weight.
When ascending, the weight is reduced by adding the air in the air accumulator into the ballast tank and draining the seawater in the ballast tank.
Such adjustment of the weight of the submersible is necessary for the ascent of the submersible.

However, in this submerged ascent system using a ballast tank and an air accumulator, the number of submerged ascents in the sea is limited, and when the air pressure in the air accumulator decreases, the air pressure must be temporarily adjusted by going out to the sea.
Further, since a ballast tank or the like is installed in the submersible craft, a comfortable boat interior space cannot be expected, and the boat operation is performed in a limited narrow space.

  The present invention improves the submerged levitation system using the increase / decrease of the weight in the conventional submersible craft, and completely separates the submarine craft from the submerged levitation system, thereby solving the problem related to submerged levitation in the submersible craft. It is something to try.

  In order to solve this problem, seawater flow into and out of the ballast tank is adjusted with high-pressure air in the accumulator, and the current system for ascending and submerging by increasing or decreasing the weight of the submersible is the same. However, it is only necessary to intentionally increase or decrease the volume of a part of the submersible craft and change to a submerged levitation system by increasing or decreasing the buoyancy relative to the volume.

FIG. 1 is a front view showing the relationship between the container 1 and the stretchable membrane 2 for intentionally increasing or decreasing the volume.
The container 1 and the stretchable film 2 are filled with high-pressure air. A weight 3 is placed in the container 1 and the stretchable film 2 filled with the high-pressure air, and is attached to the bottom of the stretchable film 2 by adhesion.
When the container 1 is above, the stretchable film 2 has a maximum volume due to the gravity of the weight 3. When the container 1 is below, the volume of the stretchable film 2 is minimized due to the gravity of the weight 3.
However, there is no change in weight in both states.

FIG. 2 is a cross-sectional view showing the relationship between the container 1 and the stretchable membrane 2.
FIG. 3 is a view of the hollow disk 4 for making the stretchable membrane 2 bellows.
In the stretchable film 2, hollow disks 4 are attached at regular intervals to form a bellows shape so that the stretchable film 2 can be smoothly stretched and contracted. When the stretchable film 2 has a bellows shape, it can be smoothly stretched.
Moreover, by attaching the hollow disc 4, the stretchable membrane 2 can maintain the same cross-sectional shape even under high water pressure.

  The container 1 and the submersible are connected by a mounting material 5, and the top and bottom of the container 1 and the stretchable membrane 2 can be changed around the mounting material 5.

An air accumulator is installed in the submersible craft and connected to the container 1 through the hollow material 6.
The pressure of the air in the container 1 and the stretchable membrane 2 can be freely changed by adjusting the air accumulator.
As a result, the stretchable film 2 can be reliably stretched and contracted.
In addition, as a response | compatibility with respect to the high water pressure in the deep sea, the expansion-contraction of the expansion-contraction film | membrane 2 can be performed more smoothly by installing a jack in the container 1. FIG.

The present invention uses the principle of buoyancy proportional to the volume of an object in water or the like = Archimedes' principle, and attempts to make a submersible levitate.
There is only a difference in buoyancy, and there is no need to allow seawater to flow into or out of the ballast tank in the submersible, so seawater does not enter the submersible, reducing the risk.
Further, the ballast tank is unnecessary, and the space can be used for other purposes, and the energy consumption can be suppressed.

  It is a front view of the apparatus for obtaining different buoyancy in the sea.   FIG. 2 is a sectional view of the device according to FIG. 1.   It is a figure of the hollow disc 4 for making the elastic membrane 2 into a bellows shape.

Embodiments of the present invention will be described below.
FIG. 1 shows an apparatus for obtaining different buoyancy, in which a weight 3, a container 1, and a stretchable film 2 are integrated.
Depending on the state of the top and bottom of the apparatus of FIG. 1, the weight 3 performs a piston motion due to the relationship with gravity.
Accordingly, the stretchable film 2 changes its volume from the maximum to the minimum and from the minimum to the maximum, thereby creating different volumes.

By attaching the hollow disc 4 to the stretchable membrane 2 at equal intervals, the stretchable membrane 2 becomes bellows-like and can be stretched and contracted more smoothly.
As a result, even if the weight is the same, it is possible to produce different states of buoyancy.
The stretch membrane 2 must be sealed so that seawater or the like does not enter the container 1 and the stretch membrane 2.

Due to the piston movement by the weight 3, the volume of the stretchable film 2 changes. At that time, in order to adjust the air pressure existing in the container 1 and the stretchable membrane 2, it is necessary to connect the air accumulator installed in the submersible and the container 1.
By connecting the gas accumulator and the container 1 with the hollow material 6, the stretchable membrane 2 having a bellows shape can be stretched and contracted more smoothly.
