DESCRIPTION OF THE INVENTION

The field of technology

Buoyancy motor; buoyancy; pumping gas

View the problem

In many technical areas, there is a need for economical, reliable engines whose operating range is at low engine speeds. Many engine designs are known to operate at higher rpm (electric motor, internal combustion engines). Reduction gears of various designs (gear, planetary, belt ...) are used to reduce the rotational speed of existing engines, which is associated with high costs.

In many industries (eg food, medicine, pharmacy, etc.), an ecologically sound engine must be provided without the discharge of liquids or gases produced as combustion products or as a result of lubrication.

The engine provides reliable continuous operation with low energy consumption required for its operation, making the engine operation environmentally sound.

The state of the art

Engines that use the force of buoyancy as a principle of their operation are not found in the literature.

Description of the new solution

The object of the invention is a buoyancy motor which utilizes for its continuous operation the force of buoyancy caused by pumping gas from an inflatable balloon in the upper position into an inflatable balloon in a lower inferior position, the inflatable balloons being submerged in the liquid. The engine provides reliable continuous operation with low power consumption required for its operation.

A rotary part is mounted on the motor axis, which is immersed in a fluid with the highest density and the lowest possible viscosity. As the fluid density increases, the buoyancy force increases, reducing the required motor size.

The rotating part consists of several arms, the weight being balanced around the pivot, to produce as little additional force as possible during engine operation and to keep the engine running as evenly as possible. An inflatable balloon is mounted on each arm.

The inflatable balloon is filled in the lower position with air or other neutral gas, with the overpressure or balloon overpressure being slightly higher than the hydrostatic pressure, the hydrostatic pressure being the pressure caused by the fluid column at the depth at which the inflatable is located. balloon.

Due to the action of the buoyancy force, the submerged rotating part rotates about its axis, the higher moment around the pivot being caused by a single leg in the position when the leg is in a horizontal position, since then the force of buoyancy is greatest.

In the upper position and the downward movement of the balloon, the balloon is emptied so that the buoyancy force does not cause a negative momentum on the axis of rotation. When emptying the balloon in the upper position, it is possible to pump the gas in the balloon into a lower balloon or use the expansion work of the gas when emptying the balloon. When pumping gas from balloon to balloon, the energy consumption for filling is about 50% lower than when inflatable balloons are being filled constantly with new gas.

When the inflatable balloon is inflated in the lower position, the buoyancy force moves it upwards, in a circular motion. In the upper position, inflate the balloon and fill the balloon in the lower position. The engine requires at least two inflatable balloons, but the number of balloons can be arbitrary, even or even. By increasing the number of balloons, a more continuous continuous torque on the motor axis is achieved, which results in a smoother operation of the device. The higher the distance between the upper and lower balloon positions, the better the engine efficiency. Also, the greater the utilization of the device, the denser the liquid.

The motor housing is attached to the fluid container. The shaft of the engine is sealed against the ingress of fluid outwards, and the bores in the shaft are sealed to prevent compressed gas, preferably air. The direction of rotation of the motor shaft depends on the set program in the controller, which in a specific position switches the three-way valves, thus controlling the filling or emptying of inflatable balloons, or pumping air from one inflatable balloon to another. The pressure of the air or other gas in the system is controlled by the pressure transducer. If the system pressure drops, it rises again with the compressor.

A compressor or fan (if no expansion work is made of the balloon gas) pumps the gas from the balloon in the upper position to the balloon in the lower position. Using a frequency-controlled compressor or fan motor saves up to 50% of the required electricity so that the engine starts at a minimum speed in its initial state and then increases the pressure to the final pressure by increasing the pressure. If the system pressure is high enough, the solenoid valve is closed and the compressor is stationary.

For the positioning of the shaft and thus the whole rotating part, a sensor, preferably an optical one, is continuously monitored, which continuously monitors the position of the shaft to ensure the synchronous operation of the buoyancy engine.

The design and construction of the engine must be carried out in such a way as to maximize the efficiency of the engine, paying particular attention to the sealing of the compressed gas while minimizing friction.

The inflatable balloons are made of a material that, when emptied, occupies as little space as possible with low weight, thus increasing the overall efficiency of the buoyancy engine. The shape and arrangement of the balloons can be arbitrary, inflate in the lower position in the direction of rotation and empty in the upper position in the direction of rotation.

Multiple inflatable balloon supports can be attached along the length of the shaft, and the valves are connected to all balloons in the same position (for example at the top).

Instead of inflatable balloons, other designs can be used to achieve similar efficiency in simplified engine operation, for which materials with very low densities that have the ability to expand or shrink at a specific moment are particularly interesting.

Systems that utilize natural cooling sources, such as air-cooled refrigerators, are used to cool compressed gas s, and partially cool the gas in a liquid.

The essence of the invention is explained in more detail below with a description of an embodiment and the accompanying drawings, the drawings being part of the present patent application and the drawings show:

Figure 1 shows an inflatable balloon 1, a three-way valve 2, a compressor or fan 3, a pressure transducer 4, a compressor 5, a solenoid valve 6, a regulator 7, an optical sensor 8, a shaft 9, a motor housing 10, a container with liquid 11.

Figure 2 shows an inflatable balloon 1, a fluid container 11.

In the embodiment shown, the rotary part of the engine immersed in the liquid consists of four arms, each having an inflatable balloon 1. The inflatable balloon 1 is filled with gas in the lower position.

When the inflator 1 is inflated in the lower position, the buoyancy force moves it up, causing circular motion around the motor axis. In the upper position, inflate balloon 1 and empty the inflator 1 in the lower position.

The housing of the motor 10 is fixed to the container with fluid 11. The direction of rotation of the shaft 9 depends on the program set in the regulator 7, which in a specific position switches the three-way valve 2, which controls the filling or emptying of inflatable balloons, or pumping air from one inflatable balloon to the other. The gas pressure in the system is controlled by a pressure transducer 4. If the system pressure drops, it is raised again by the compressor 5.

The compressor or fan 3 pumps gas from the inflatable balloon 1 in the upper position to the inflatable balloon 1 in the lower position. If the system pressure is high enough, solenoid valve 6 is closed and the compressor is stationary.

Optical sensor 8 is installed for positioning the shaft and thus for the whole rotating part, which constantly monitors the position of the shaft to ensure the synchronous operation of the buoyancy engine.

It is to be understood that the described solution can also be implemented in a different design that does not alter the essence of the invention.
