Thereby, one flow path from the supply port of the main rotating body to the discharge port through the inside of the main rotating body and the other flow path from the discharge port of the main rotating body to the outside of the main rotating body to the supply port. When gas convection occurs, the convection causes the main rotor and the sub-rotator to rotate via the turbine. In this turbine, gas is injected from an injection port in a direction opposite to the outer circumferential direction of the main rotating body, and the main rotating body is rotated. In this case, since the gas is injected in the circumferential direction, a situation in which the gas collides with the end face of the sub-rotator and the loss that does not contribute to rotation is increased as in the related art is suppressed, and the rotation efficiency is greatly improved.

The liquid storage tank 92 is filled with carbon dioxide, contracts by the supply of the liquid, expands when the solenoid valve 94 is opened, and causes the liquid to be injected from the injection nozzle 93.

Further, an oil passage 96 for supplying a liquid as lubricating oil is provided to the bearing of the main rotating shaft 23 of the main rotating body 20 and the bearing of the subsidiary rotating shaft 31 of the subsidiary rotating body 30.
The oil passage 96 is provided in the support shaft 11, and opens at one end of the support shaft 11 to open the thrust bearings 24, 32.
And a path that opens to the main rotation shaft 23 at the other end of the main rotating body 20. In addition, the slave rotor 30
The liquid is supplied to the bearing 33 provided on the partition wall 12 on the sub-rotation shaft 31 at the other end. This lubricating liquid is
The liquid is collected at the lower end of the outer shell 10,
Collected to 0.

Therefore, when power is generated by the convection temperature difference driving apparatus according to the embodiment of the present invention, the following operation is performed. First, at the time of starting, the start means 90 is driven. In this case, the liquid is stored in the storage tank 92 from the branch pipe 92a branched from the liquid circulation pipe 60 in a high pressure state in advance. Then, the solenoid valve 94 is opened and the injection nozzle 9 is opened.
From 3, the liquid in the liquid storage tank 92 is jetted toward the rotating fan 91. As a result, the rotating fan 91 starts to rotate, the sub rotator 30 is rotated, and the main rotator 20 also starts to rotate in the same direction. In this case, since the main rotator 20 and the sub rotator 30 are started by the start means 90, the start-up is performed quickly and reliably, and the subsequent rotation is performed smoothly.

In this state, the liquid is supplied to the injection port 61 of the support shaft 11.
From the discharge port 15 into the main rotating body 20 through the support shaft 11 to cool the gas in the main rotating body 20, pass through the turbine 40, pass through the recovery port 62, pass through the liquid circulation line 60, and again It is guided to the inlet 61. In the middle of the liquid circulation line 60, the liquid heated by the cooling of the gas is cooled by the cooling unit 6.
3 again cools. On the other hand, gas flows in from the outlet 71, and the ventilation path 7 on the inner wall of the one end side rotating bodies 20a, 30a.
6 flows out from one end side inlet 74 and flows out from the other end side outlet 75, and the outflowing high-temperature gas passes through the other flow path Rb and also passes through the one flow path Ra of the main rotating body 20 and the one flow path Ra
Is cooled by the liquid to reach the turbine 40. Then, the air is returned from the return port 72 to the outlet 71 through the gas circulation line 70. In the middle of this gas circulation line 70,
The cooled gas is heated by the heating unit 73.

As a result, the flow path Ra from the supply port 21 of the main rotating body 20 to the discharge port 22 through the interior of the main rotating body 20 and the discharge port 22 of the main rotating body 20
Convection of the gas passing through the other flow path Rb that reaches the supply port 21 through the outside of the main rotor 20 and the main rotator 20 and the sub rotator 30 are rotated in the same direction via the turbine 40 by the convection. In the turbine 40, gas is injected from the injection port 42 in a direction (Fb) opposite to the outer circumferential direction (Fa) of the main rotating body 20, and the main rotating body 20 is rotated. In this case, since the gas is injected in the circumferential direction contributing to rotation, the situation where the gas collides with the end face of the sub-rotating body and loss that does not contribute to rotation increases as in the related art is suppressed, and the rotation efficiency is reduced. It can be greatly improved. Further, the turbine 40 has a guide passage 4 that guides gas from the inflow port 41 to the injection port 42 so as to inject the gas from the injection port 42.
3, the gas is reliably injected in the direction opposite to the outer circumferential direction of the rotating body. Further, the injection port 42
Are arranged in an equiangular relationship along the outer circumference,
The gas is evenly injected in the circumferential direction, so that the rotation of the main rotating body 20 is stabilized. Further, since the turbine 40 is provided with the injection port variable mechanism 50, when the rotation speed of the main rotating body 20 is low, the injection port 42 is reduced, and the rotation speed of the main rotation body 20 is increased. Since the injection port 42 expands due to the accompanying increase in centrifugal force, the flow velocity of the gas is made uniform when the rotation speed of the main rotating body 20 is low. Is performed smoothly.

Then, the gas injected from the injection port 42 of the turbine 40 collides with the plurality of receiving plates 55 of the sub-rotator 30. For this reason, a reaction force is generated by the receiving plate 55, and accordingly, the rotational force of the main rotating body 20 is increased, and the rotational efficiency is improved. Further, the receiving plate 55 transfers the received gas to the main rotating body 2.
0 is formed in a shape to flow in the outer rotational circumferential direction (Fa), and the gas flowed by the receiving plate 55 is supplied to the plurality of receiving bodies 5 arranged in a row on the outer periphery of the main rotating body 20.
6 received. Accordingly, the main rotating body 20 receives a force in the outer rotational circumferential direction (Fa) by the gas flowed by the receiving plate 55, and accordingly, the rotating force of the main rotating body 20 increases, and the rotation efficiency increases. Can be improved.

Further, the main rotator 20 and the sub rotator 30
Are one end rotators 20a and 30a and the other end rotator 20a.
b, 30b, and one end side rotating body 20
a, 30a and the other end-side rotator 20b, 30b are divided so that they can be relatively displaced in a direction orthogonal to the axial direction.
Even if the a and 30a and the other end side rotators 20b and 30b oscillate in the lateral direction, they relatively displace each other, so that this oscillation is absorbed, and therefore, the rotation is performed smoothly. In addition, the one end rotators 20a and 30a and the other end rotators 20b and 30b
Between the overlapping portions 27 and 37 at the divided end portion of the cushion member 2
With the interposition of the 8, 38, the run-out is absorbed without the split ends colliding with each other, so that the rotation is performed more smoothly. Further, in the sub-rotational body 30, the ventilation path 76 that allows the gas from the outlet 71 to flow from the one-side inlet 74 to the other-side outlet 75 is provided on the inner wall thereof, so that the high-temperature gas flows under the other flow path Rb. Since the air can be blown out from the side, an updraft can be easily generated, so that the energy of the convection of the gas can be increased. Further, since the ventilation passages 76 are arranged in a large number along the inner wall of the slave rotor 30, an upward airflow can be generated over the inner periphery of the slave rotor 30, and the airflow is uniformized accordingly, so that the rotation Is stabilized. Further, since the wall portion of the ventilation passage 76 is formed in a mountain shape, heat exchange between the gas passing through the inside of the ventilation passage 76 and the gas in the other flow passage Rb is easily performed, and the gas in the other flow passage Rb is reliably removed. At high temperature.

Further, the liquid is ejected and ejected in the form of a shower from the liquid ejection port 15 formed on the support shaft 11, and the ejection port 15 is shaped so as to be ejected and ejected in the rotation direction of the main rotating body 20. Since the liquid ejected from the ejection port 15 is received by the receiving member 57 provided on the inner wall of the main rotator 20, the main rotator 20 receives a force in the rotation direction. The rotational force of the main rotating body 20 increases, and the rotational efficiency is improved. Furthermore, the gas is blown out from the supply port 21 of the main rotating body 20 to the one flow path Ra, but the supply port 21 is formed in a shape to be flown in the rotation direction of the main rotating body 20, Since the gas blown out to the receiving member 57 provided on the inner wall of the rotator 20 is received, the main rotator 20 receives a force in the rotational direction. At this point, the rotational force of the main rotator 20 increases. The rotation efficiency is improved.

In the power acquisition mechanism 80, the main rotating body 2
Since the 0 and the sub-rotating bodies 30 rotate in the same direction, power is obtained from both of them. That is, the rotation of the main rotating body 20 is transmitted to the main gear 81 of the sub-rotating body 30 via the interlocking gear mechanism 83, and the sub-rotating body 30 itself also rotates the main gear 81. The power is transmitted to the power generator 85 and the power is generated by the power generator 85. In this case, the main rotating body 2
Since power is obtained from both the zero and the sub-rotational body 30, the energy conversion efficiency is extremely improved. In the rotation of the main rotator 20 and the sub rotator 30, the main rotator 20
Of the main rotary shaft 23 and the sub rotary shaft 3 of the sub rotary body 30
Since the liquid is supplied to the first bearing portion through the oil passage 96 as lubricating oil, the rotation is performed smoothly.

In addition, the run-out is absorbed without collision between the divided ends, so that the rotation is smoothly performed.

In this case, since the gas is injected in the circumferential direction that contributes to the rotation, the situation where the loss that does not contribute to the rotation as in the related art increases is suppressed, and the rotation efficiency is greatly improved. Then, the gas injected from the injection port 42 of the turbine 40 collides with the plurality of receiving plates 55 of the outer shell 10. For this reason, a reaction force is generated by the receiving plate 55, and accordingly, the rotational force of the main rotating body 20 is increased, and the rotational efficiency is improved. Further, the receiving plate 55 is formed in a shape for causing the received gas to flow toward the outer circumferential direction (Fa) of the main rotating body 20. It is received by a plurality of receiving bodies 56 arranged in a row on the outer periphery of the body 20. Thereby, the main rotating body 2
0 receives a force in the outer rotational circumferential direction (Fa) by the gas flowed by the receiving plate 55,
