Abstract

PURPOSE:To generate clean energy by floating and sinking a float-and-sink cylinder in a water bath while expanding and contracting a variable volume bag through a driving machine to generate difference of buoyancy, and press- feeding air in the water bath to air conduits. CONSTITUTION:A variable volume bag 5 is expanded and contracted by driving a driving machine 7. A float-and-sink cylinder 2 in a water bath 1 is floated and sunk by the difference of buoyancy generated according to the expansion and contraction. Air in the water bath 1 is suctioned and discharged through air conduits 3a, 3b. When the variable volume bag 5 is expanded, air in the water bath 1 is press-fed through the air conduits 3a, 3b. Atmospheric air is introduced into a space in which negative pressure is generated between a water level and the float-and-sink cylinder 2 through the air conduits 3b or 3a. When the bag is contracted, air is suctioned and discharged in the reversed manner. The air energy is circulated to an air flow exchanger to form a serial air flow circuit. A turbine in the circuit, for instance, is driven by jet from a nozzle 12 to obtain driving force of a power generator, thereby power is generated.

FIELD OF THE INVENTION The present invention relates to a method of generating wind energy.

[0002]

With respect to the energy problem, global warming is causing global warming and environmental destruction such as acid rain due to CO ₂ emission from fossil fuels.
In addition, there is a problem such as pollution by nuclear energy radiation materials. Although natural energy is clean energy, it is difficult to use it stably and sustainably because it is restricted by geographical and meteorological conditions, and there is a cost problem.

[0003]

[Means for Solving the Problems] As means for solving the above-mentioned problems, air in the water tank is pumped by a floating / sinking cylinder having a function of levitation and settling due to gravity and buoyancy in the water tank, and this wind force is generated. The method will be the means of solution.

In order to embody the above-mentioned means, the water tank is provided with a closed lid at the upper part, and an air guide tube is provided at the center of the upper part and the center in the water tank.

The structure of the floating and sinking cylinder is about 1/2 the height of the water tank, the diameter is slightly smaller than the diameter of the water tank, the upper part has a closing lid, and the lower part is open. The inner circumference of the lower part is equipped with a metering tank that holds most of the weight of the floating and sinking cylinder, and a variable capacity bag with suction and exhaust that has the function of expansion and contraction in a part of it, and the drive machine that drives this. Composed.

[0006]

With the above-described structure, the floating / sinking cylinder in the water tank expands / contracts the variable capacity bag through the drive unit, and the floating / sinking cylinder has a difference in buoyancy, so that the floating / sinking motion occurs. When ascending, the air in the water tank is pumped from the upper part of the closed lid of the water tank by the air guide tube, and at the same time, the air guide tube in the water tank has a negative pressure in the space between the floating and sinking cylinders and the water surface. And becomes a suction state. On the contrary, in the case of sedimentation, the opposite situation will occur.

The alternating flow in the opposite direction is converted by an air flow converter for converting the flow in one direction. This flow is injected as a jet flow from a nozzle to drive a turbine, and this flow is returned to an air flow converter to form a series of air flow circuits.

The function of the air flow converter will be explained in the examples.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the above series of air flow circuits, referring to the drawings and explaining the embodiment with reference to FIG. 2, the air guide tubes 3a and 3b from the water tank 1 are connected to the recirculation chamber 9 of the air flow converter 8 and the air supply. It is branched and connected to the chamber 10. Where for example
When the air guide tube 3a is pressure-fed, the air guide tube 3b is in a suction state.

The conversion valve of the air flow converter 8 at this time is a valve of the air supply chamber 10 connected to the air guide tube 3b with the valve 9a of the reflux chamber 9 closed and the valve 10a of the air supply chamber 10 open. 10b is closed, and the valve 10a of the reflux chamber 9 is open.

In the state of the conversion valve of the air flow converter 8 described above,
The airflow of the air guide tube 3a flows into the air supply chamber 10 and the air supply tube 11
The nozzle 12-the casing 14 of the turbine 13-the recirculation pipe 15-the recirculation chamber 9 form a series of airflow circuits.

The turbine 13 in the above series of airflow circuits
Is driven by the jet flow ejected from the nozzle 12, and this is used as the driving force of the generator 16 to generate electricity.

Incidentally, the speed of the jet flow of the nozzle 12 depends on the water tank 1.
And the diameter of the nozzle 12 and the floating and sinking speed of the floating / sinking cylinder 2 are determined. For example, the diameter ratio is 100: 1,
If the speed of ascent and sedimentation is 1 cm / S, the jet flow velocity is 1
It becomes 100 m / S, which is 10,000 times as much, and becomes a great amount of energy.
