In order to increase or decrease the volume of the body, the shape memory alloy spring is operated by utilizing the phase transformation of the shape memory alloy by thermal energy such as hot liquid, hot air, cold liquid, cold air, etc., and the spring force with the bias spring This is a device that uses the buoyancy imbalance caused by the increase / decrease in the volume of the buoyancy body caused by the difference between the rotation bodies to rotate the rotation body and generate electric power using the kinetic energy.

At present, electricity is generated by large-scale power generation facilities, or by private power generation at factories, etc., or by individual small-scale power generation at homes, etc. The damage of nuclear power and nuclear fuel waste disposal, thermal power and natural gas emit CO2, and there are problems with hydropower and renewable energy such as geothermal, solar, solar, wind, etc. .
In-house power generation at factories, etc. also has problems such as CO2 emissions and fuel price fluctuations, and the use of renewable energy such as solar and wind power in each household is both unstable and unstable depending on the climate. The scale is also limited.

In order to solve the above problems, it is necessary to promote the use of renewable energy. The present invention is a device that generates heat by using heat energy such as factory exhaust heat, exhaust hot water, exhaust cooling water, hot spring, hot liquid, hot air, cold liquid, cold air, etc. Useful as energy.

Since the present invention uses rotational energy due to buoyancy, it is a power generation device capable of stable operation 24 hours a year without being influenced by the climate, and in combination with a high-efficiency heat pump, using its hot and cold water, This could be a self-contained generator that can be used at home.

Hereinafter, the power generator according to the present invention will be described based on the embodiments shown in FIGS. 1, 2, 3, 4, 5, 6, 6, 7, 8, 9, 10, and 11. .

1 and 5, the buoyancy bodies 2, 3, 4 and the O-ring 11 and the intake / exhaust port 9 constitute a variable volume buoyancy body. The bias spring 8 attached to the variable volume buoyancy body, the buoyancy body 4 and the case A6 The volume of the buoyancy bodies 2, 3, 4 is increased or decreased by the attached shape memory alloy spring 5.

In FIGS. 1 and 6, the buoyancy bodies 2, 3, and 4 increase and decrease the volume by the difference in spring force between the shape memory alloy spring 5 and the bias spring 8. When the temperature is lower than the transformation temperature of the shape memory alloy, the spring force of the bias spring 8 exceeds the spring force of the shape memory alloy spring 5, so that the volume of the buoyant bodies 2, 3 and 4 decreases, and the transformation temperature of the shape memory alloy At higher temperatures, the spring force of the shape memory alloy spring 5 exceeds the spring force of the bias spring 8, so that the volume of the buoyancy bodies 2, 3, 4 increases.

5 and 10, the buoyancy bodies 2, 3, and 4 increase and decrease the volume by the difference in spring force between the shape memory alloy spring 5 and the bias spring 8. When the temperature is higher than the transformation temperature of the shape memory alloy, the volume of the buoyant bodies 2, 3 and 4 decreases because the spring force of the shape memory alloy spring 5 exceeds the spring force of the bias spring 8, and the transformation temperature of the shape memory alloy When the temperature is lower, the volume of the buoyant bodies 2, 3, 4 increases because the spring force of the bias spring 8 exceeds the spring force of the shape memory alloy spring 5.

In FIGS. 1, 4, and 5, the case A 6, the case B 1, and the cam 15 control the ball 7, and the ball 7 restricts the increase and decrease in the volume of the buoyancy bodies 2, 3, and 4. When the rotating body 13 is rotated, the case B1 is rotated by the cam 15, and when the ball 7 is released in the range of A and B in FIG. 4, the ball 7 is separated from the buoyant bodies 2, 3, 4 and the shape memory alloy spring. 5 can be released to increase or decrease the volume. Subsequently, the buoyancy bodies 2, 3, and 4 are locked by the ball 7 in the range of C and D in FIG. 4, and the volume cannot be changed.

1, 2, 3, and 4, the buoyancy bodies 2, 3, and 4 are transformed in the shape memory alloy in the range of D in FIG. 4 in the state of C in FIG. When the temperature falls below the hot liquid surface, the expansion force is caused by the difference in spring force between the shape memory alloy spring 5 and the bias spring 8, but in the range of D in FIG. The shape memory alloy spring 5 is locked by the case A6, the case B1, the ball 7 and the cam 15, so that the volume of the buoyancy bodies 2, 3 and 4 does not increase. However, in the range of FIG. 4A, the buoyancy bodies 2, 3, 4 and the shape memory alloy spring 5 are released by the case A6, the case B1, the ball 7, and the cam 15, and the volume of the buoyancy bodies 2, 3, 4 is the shape memory. The alloy spring 5 overcomes the spring force and hydraulic pressure of the bias spring and increases to increase the buoyancy in the liquid. Therefore, the rotating body 13 rotates due to an imbalance of buoyancy, and the shape memory alloy spring 5 is subsequently cooled by cold air, cold liquid, etc. at a temperature lower than the transformation temperature of the shape memory alloy in the range of B in FIG. As a result, the spring force is reduced, and the buoyancy bodies 2, 3, and 4 are reduced in volume by the spring force of the bias spring, and then locked in the range of C in FIG. 4, and in the range of D in FIG. 4 below the liquid level. Continue to enter and rotate. The generator 16 is rotated by the rotational force to generate power.

2, 3, 4, and 5, the buoyancy bodies 2, 3, and 4 are transformed in the shape memory alloy in the range of D in FIG. 4 in the state of C in FIG. When entering below the cold liquid surface at a temperature lower than the temperature, a force that expands due to the difference in spring force between the shape memory alloy spring 5 and the bias spring 8 works, but in the range of D in FIG. The shape memory alloy spring 5 is locked by the case A6, the case B1, the ball 7 and the cam 15, so that the volume of the buoyancy bodies 2, 3 and 4 does not increase. However, in the range of FIG. 4A, the buoyancy bodies 2, 3, 4 and the shape memory alloy spring 5 are released by the case A6, the case B1, the ball 7, and the cam 15, and the volume of the buoyancy bodies 2, 3, 4 is 8 overcomes the spring force and hydraulic pressure of the shape memory alloy spring 5 and increases the buoyancy in the liquid. Therefore, the rotator 13 rotates with an imbalance in buoyancy, and subsequently heats the shape memory alloy spring 5 with hot air, hot liquid, etc., at a temperature higher than the transformation temperature of the shape memory alloy in the range of B in FIG. As a result, the spring force is increased and the buoyancy bodies 2, 3 and 4 are compressed and the volume is reduced. Then, the buoyancy bodies 2, 3 and 4 are locked in the range C in FIG. 4 and enter the range D in FIG. Continue. The generator 16 is rotated by the rotational force to generate power.

6 and 10, the buoyancy bodies 2, 3, 4, the O-ring 11, the intake / exhaust port 9, and the joint 27 constitute a variable volume buoyancy body, which is attached to the joint 26 and the joint 27 and disposed inside the pipe 25. The volume is increased or decreased by the difference in spring force between the shape memory alloy spring 5 and the bias spring 8 attached to the buoyancy bodies 2, 3, 4. Hot liquid, hot air and cold liquid used to operate the shape memory alloy spring 5, cold air is taken in from the intake pipe 23, rotary valve 21, valve case 20, pipe 25, joint 26, joint 27, valve The exhaust gas passes through the case 20 and the rotary valve 21 and is discharged or circulated from the drainage pipe 24.

In FIGS. 6, 7, 8, and 9, the rotary valve 21 is fixed to the support leg 14 together with the intake and suction pipes 23 and the exhaust and drainage pipe 24, and the valve case 22 rotates together with the rotating body 13. In the range of A of the rotary valve 23, warm liquid and hot air having a temperature higher than the transformation temperature of the shape memory alloy are sent to the pipe 25, the joint 26, and the joint 27, and the shape memory alloy spring 5 disposed in the pipe 25. Is heated to increase the spring force and overcome the spring force and hydraulic pressure of the bias spring 8 attached to the buoyancy bodies 2, 3, 4, and the volume of the buoyancy bodies 2, 3, 4 increases to increase the buoyancy in the liquid. Increase. Subsequently, in the range B of the rotary valve 21, cold liquid or cold air having a temperature lower than the transformation temperature of the shape memory alloy is sent to the pipe 25, the joint 26, and the joint 27, and the shape memory alloy spring 5 disposed in the pipe. Is cooled, and the spring force becomes weaker than the spring force of the bias spring 8, so that the volume of the buoyancy bodies 2, 3, 4 decreases. Therefore, the buoyancy of the rotator 13 in the liquid is unbalanced and rotates, and the generator 16 is rotated by the rotational force to generate power.

In FIGS. 7, 8, 9, and 10, the rotary valve 21 is fixed to the support leg 14 together with the intake and suction pipes 23 and the exhaust and drainage pipes 24, and the valve case 20 rotates together with the rotating body 13. In the range of A of the rotary valve 21, cold liquid and cold air having a temperature lower than the transformation temperature of the shape memory alloy are sent to the pipe 25, the joint 26, and the joint 27, and the shape memory alloy spring 5 disposed in the pipe 25 is cooled. The spring force is reduced, and the spring force of the bias spring 8 attached to the buoyancy bodies 2, 3 and 4 overcomes the spring force and hydraulic pressure of the shape memory alloy spring 5, so that the volume of the buoyancy bodies 2, 3 and 4 is Increase and increase buoyancy in liquid. Subsequently, in the range B of the rotary valve 21, hot liquid and hot air having a temperature higher than the transformation temperature of the shape memory alloy are sent to the pipe 25, the joint 26, and the joint 27, and the shape memory alloy spring disposed in the pipe. 5 is heated, and the spring force becomes stronger than the spring force of the bias spring 8, so that the buoyancy bodies 2, 3, and 4 are compressed and the volume is reduced. Therefore, the rotating body 13 in the liquid rotates due to an imbalance of buoyancy, and the generator 16 is rotated by the rotational force to generate electric power.

  FIG. 11 shows a relationship diagram between the heat pump and the buoyancy rotating device. In the heat pump, the low-temperature heat transfer liquid evaporates while taking heat from the heat source in the evaporator, turns into a low-temperature refrigerant gas, then compresses in the compressor, turns into a high-temperature high-pressure gas, and then heats up to the hot liquid in the condenser. Is cooled to become a condensate, and is finally depressurized and reduced in temperature by an expansion valve, returns to the low-temperature heat transfer medium, and enters the evaporator again. The hot liquid used in the buoyancy rotator is heated by the condenser in the heat pump. Moreover, the cold liquid used with a buoyancy rotary body is cooled with the evaporator in a heat pump.
