English Abstract


This invention relates to air balloon like device having aluminum pipe in the
middle of air bag. This air bag is made by the material like inflatable boat.
The
air bag may readily be secured to strongly with the pipe using parts like
ropes,
cramps, rubber gaskets, nuts, steel plate, hook and bracelet. This device will
be
used for lifting ships or boats up form aground or controlling the ship's
balance.
We can escape from any difficulties without pumping oil on the sea, also this
device can be used to recover ships from deep sea bottom.


Claims

Note: Claims are shown in the official language in which they were submitted.


Claims
1. The Principle of the combination that lifting ships up,
2. The methods of making air bag with pipe and all parts including ropes (or
nets) and the bracelet with the holes at the hull of the ship. This
combination include methods of making air bags that capable of working at
the below water level.

Description

Note: Descriptions are shown in the official language in which they were submitted.

Background of the Invention
Summary of the Invention.
This device is similar principal of inflatable boats. The inflatable boats
float on
the surface of the water by balancing the water pressure ( or resistance) and
the
boat's floating forces but difference of this device is as following. This
device
is using floating force at the below water level and using aluminum pipe to
hold
the air bag strongly stay in position below water level. As we knew the
pressure
of the water at the 10 meter below the water level is ~ 2 ATM or ~2kg/cm2
cm2 is square cm). And the pressure at the water level is ~1 ATM or =1 kg/cm2
(cm2 is square cm2). If an air bag with no air in the bag draw down 10 meter
below water level and start pump air in slowly, same time push down on the top
of the air bag , it the forces of pushing downward are greater than the air
bag's
floating force, then this air bag will stay in the water.
Relativity pressure between two force that is the air pressure and water
pressure
against the air bag's material will eliminate each other's pressure .
according to
this theory , forces or pressure affecting fiber materials in the water will
be
relatively less than in the air , because of the apposite direction of
pressure will
eliminate each other reduce the pressure affecting to the air bag's material.
when the pressure of the air bag is =2kg/cm2 , relativity pressure at the
lower part
of the air bag at 10 meter below water level will be almost zero and top part
of
the air bag at the water level will be =1 kg/cm2,
this means a 10 meter diameter of air bag with 2kg/cm2 air pressure will stay
in
the water more conformable than in air but this air bag have to hold down with
the force of same number volume of the air bag.
This device's air bag can hold down below water level using pipe, cramps,
ropes,
nuts, rubber gaskets, hooks, steel plate, and bracelet. The sizes of this
supporting

CA 02284295 1999-08-30
parts will vary depend on the sizes of the air bags. The floating force or the
force of pulling down will be the same amount of forces that lift the ship up
.
This air bag will grow slowly from the top part of the bag at the below water
level
when applying air pressure in the air bag because of the greater water
resistance
forces ) at the deep water level. A 10 meter diameter air bag will produce 500
tons of lifting up force, this device needs 500 tons holding capacity of all
parts
including air bag, pipe, ropes, and other parts Small ships may need only 2 or
3
meter diameter air bag for 4 tons or 14 tons of lifting up force. This small
air bag
needs less capacity of all the parts. Smaller air bags will need lower air
pressure.
Large size of air bags needs at least 3 ATM holding capacity of fiber material
like inflatable boats . The material of the inflatable boats have maximum = 3
ATM or 3kg/cm2 capacity. The material of the very top part of the air bag
should be ticker than middle part for supporting to connect with the pipe to
stay
in same position and support hold down forces. Lower part of the material of
the air bag should be two or three times ticker than middle part of the air
bag for
supporting hold down forces with the pipe at the same position below the water
level . the ropes will help to pull down the air bag to stay below the water
level
and tight with the pipe and also will protect heavy floating force at the air
bag's
upper part and middle part to keep original shape.
When needed help of this device , just draw down the device in the water and
hook with the bracer at the hull of the ship and pump air in through the
pipe's air
inlet air bag will grow slowly and same time ship will move up as much as air
bag's grow. We can use the air bag just one side for balancing ships, two or
more for lifting ships up. Balancing force of the air bag will be par greater
than
internal water tank movement, because of the par greater distance from the
center gravity line of the ship than internal water tank location.
This device is already assembled completely before using it. It can be rolled
up to
keep in the storage room after air out.
This device will be used to lift large object up from deep bottom of the sea.
For
instance , large object like 10,000 tons or 20,000 tons of ships by using very
powerful air compressor and very large air bags, pipes and all parts that
capable of
large forces. Water pressure at the 2000 meter below water level could be ~
200
ATM or 200 kg/cm2, if we have air compressor, hoses and all the parts that
capable of 200 ATM air pressure, we could lift objects up close to surface
level
and move to higher sea level, next operation is easy to handle collecting the
objects. This air bag can draw down any deep sea level because this is fiber
material. It may needs large and many air bags to handle it. But large air
compressor that capable of producing higher than 200 ATM air pressure to push
air in the air bag that is at the 2,000 meter below water level. Also need one
hose
draw down to the bottom level of the water and divide ( or separate ) to
several
hoses that connect with the each air bags. And hook object up with the air
bags.
Brief description of the drawings.
The invention ( in a preferred form) is shown on the drawings wherein.

Detailed description of the drawings.
As shown on the drawings, the reference numeral 1 designates the air bag
attached with the pipe using rubber gadgets, cramps, hook, ropes, nuts, steel
plate.
the size of the parts will vary according to the size of the air bag ,
Figure 2
part a is a air inlet and supporting tight with the pipe, and air tightened.
Part b is a round and thick steel plate for holding ropes with the hook at the
end
side of steel plate. Also holding the pipe with the air bag's surface
material.
Part c , d are rubber gaskets for air tighten and holding air bag with the
pipe.
Should glued up.
Part a are nuts to keep hold the gaskets keep position and also tighten with
air
bag material and steel plate with the pipe.
Part f are cramps to hold pipes and air bag material tightly together with the
pipe at the same position and glued up and air tightened. also hold ropes
( or nets ) with the pipe. Also the first cramps will be strong rubber cramp
to reduce contact impact changing angles. The second and third cramps
will be steel cramps.
Part g is a bracelet for connecting with the bracelet at the hull of the ship
using
hook. Also hold tight material and ropes with the pipe. The hull of the
ship needs two thread holes to connect tightly with the another bracelet
and connect between two bracelet with the hooks.
Part h are 4 thread holes will be located at the lower part of the hull and
hold
bracelet with the nuts tightly. This thread holes cover up with the plastic
plate when not in use.
