Donut sealed pontoon system

[panyuming]

I'm on Mr. Novus' thread
https://overunity.com/19459/buoyancy-calculations-making-use-of-an-exception-to-archimedes-principle/

I studied and discussed buoyancy and sealing issues.
And from that, I thought about the structure of change.
Because is no longer a 'use of an exception to Archimedes'
So build another thread.

About calculating buoyancy, here it is simpler and more clear .
Fixing sealing problems may also be easier.

Figure 1 is an overall block diagram.

Among them, a string of pontoons to the left of the sprocket,
immersed in water, gets buoyancy and will rise.

A string of pontoons on the right, in a tube.
The upper mouth of this pipe is above the surface of the water.
The lower mouth of the tube is sealed.
Ideally, there is no water inside the tube, it is air.
A string of pontoons on the right did not get buoyancy .

So, the key is how the pontoon passes through the sealing mechanism
at the lower mouth of the tube,
keeping only air in the tube.

Figure 2 is a pontoon.
The middle part of the pontoon is a sealed air tank.
The parts of the pontoon that extend beyond the air tank
at both ends are made into a crown tooth shape.
There are chains connected to pontoon strings.

Figure 3 is a possible seal drive mechanism.

If it is assumed that the pontoon is a continuous tube
that goes down from the lower mouth of the air tube,
it may be easier to achieve.
But the tubular pontoon does not get much buoyancy
on the left side of the sprocket.

So the pontoons have to be made section by section.
Such a pontoon passes through the donut sealing mechanism
and there will be a large diameter change that makes sealing difficult.

Figure 2 Such a pontoon with Group edge teeth
Two pontoons up and down can form the shape of a tube.

Two continuous pontoons go through the donut sealing mechanism,
there is no diameter change, and the sealing is much simpler.

Donuts are made of suitable elastic materials.
When the pontoon passes through the doughnut,
the donut flattens a length outside the pontoon wall.
This section is press to the extent that it exceeds the length
of the crown teeth at the pontoon junction and will not leak.

The buoyancy of a string of pontoons to the left of the sprocket,
enough to pull the pontoons out of the doughnut .
But then the two pontoons that are going to pass through
the donut cannot be connected into a tube.

Therefore, by asking the donut to actively rotate itself,
it is possible to make two pontoons pass continuously
at the donut without separating.

After the pontoon passes through the doughnut,
it separates and reaches the state of chain straightening.

This requires the donut to rotate and phase in sync with the large sprocket.
It is easy to achieve using electronic control technology.

The doughnut and the red shell are also closely matched and do not leak.
Many blue drive wheels drive the donut to spin.

The deeper the left pontoon string is underwater, the more power it gets.
This depth is determined by the sealing performance of the doughnut.

Donut sealing mechanism may seem complicated, but it is more than use of an exception to Archimedes'
It is much easier to seal in a long strip.

I changed the sketch again.

The donut does not turn anymore, it is fixed instead.
The pontoon has no teeth and is changed to the sleeve method.
The pontoons in the air tubes are stacked as continuously as possible.
The drive wheels directly drive the pontoon downward.
Some water is stored at the bottom of the air tube to act as lubricant for the doughnuts.
The pontoons that move down will carry some water out between them.
Add a water level control valve to maintain the water level at the bottom of the air pipe.
Add a small water pump for start-up to drain the water from the initial air pipe.

Donuts can be selected as finished sealing rings, for marine propeller shafts. You don't have to make your own.

  I improved it again.

The connection of the pontoon was changed to the hinged method.
A small magnet is added to the pontoon to compensate for the eccentric moment.
The blue drive wheel was removed, and the buoyancy
on the left side of the sprocket pulled the pontoon down through the doughnut.
Removed the starting water pump. The upper sprocket is actively
rotated at start-up to drain water from the lower part of the air pipe.

Many layers of rubber rings spacer gaskets make up a sealed doughnut.
It does not require high precision.
Unlike the application of boat shafts, some water leakage is allowed here.
The amount of water leaking is less than the amount brought out between the pontoons,
and the water in the air pipe will remain at the level controlled by the valve.
Design the shape of the pontoon, you can adjust the amount of water carried out from the pontoon gap.

Therefore, the processing is much simpler.

This system can be used on ships that do not need fuel to sail forever.

Your new design negates the advantage of the old one.
