DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power generation device using solar heat.

[0002]

2. Description of the Related Art Conventional solar power generation devices mainly use solar cells. In addition, solar heat is often used to secure hot water.

[0003]

This has the following disadvantages. B) Since solar cells are expensive and have a short service life, power generation costs are high. B) Conventionally, solar heat is often recovered by a heat collecting plate and used as hot water. C) There is a large-scale solar power generation device, but it is not intended for the general public. The present invention has been made to eliminate these disadvantages.

[0004]

In order to achieve the above object, hot water of the solar cogeneration of the present invention is connected to a heat collecting panel 1 through a heat storage tank 2, and then through a heating pipe 5 in an evaporator 4. After passing through the water jacket of the piston mechanism 6, it is returned to the heat storage tank 2 through a double pipe 11 connected to the exhaust port 8. On the other hand, the chlorofluorocarbon is heated with hot water to a vapor pressure in the evaporator 4, is put into the piston mechanism 6 after the evaporator 4, passes through the inside of the double pipe 11 connected to the exhaust port 8, and then the oil separator The evaporator 4 is provided with a compressor 12, and further provided with a compressor 6. The evaporator 4 is stored in a liquid receiver 17 and adjusted by an evaporating pressure adjusting valve 19 to be supplied to the evaporator 4. In the power generation, the vertical movement of the piston mechanism 6 is changed to the torque of the crank 23, and the power is generated as the torque of the flywheel 22 and the generator 9 and used as a power source.

[0005]

When used, the heat collected by the heat collecting panel 1 is stored in the heat storage tank 2 with hot water, and then the heating tube 5 in the evaporator 4 is used for heating. The liquid having an increased vapor pressure is evaporated and vaporized.
Up and down the piston and crank 23 and flywheel 2
2 is rotated, and the power is generated by a power generator 9 connected to the power source. The fluorocarbon whose piston has been moved up and down is exhausted, and while being cooled by a double pipe, the oil dissolved in the piston mechanism 6 is recovered by the oil separator 12 and returned to the piston mechanism 6. On the other hand, chlorofluorocarbon and the like are compressed and liquefied by the compressor 16 and stored in the liquid receiver 17, and then the chlorofluorocarbon and the like are supplied by the evaporation pressure adjusting valve 19 according to the internal pressure of the evaporator 4 to control the internal pressure of the evaporator 4.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, heat collected by a heat collecting panel 1 is stored in a heat storage tank 2 by hot water, and a heat pump 3 evaporates the evaporator 4 from here. Through the heating pipe 5, and heats the supplied fluorocarbon and the like to a vapor pressure. After that, passes through the water jacket 10 of the piston mechanism 6, and after cooling, passes through the double pipe 11 connected to the exhaust port 8. After returning the exhausted Freon and the like to the heat storage tank 2 after cooling, the heat collecting panel 1 is
Return to On the other hand, Freon and the like create an evaporating pressure in the evaporator 4 and put the evaporating pressure through the intake port 7 of the piston mechanism 6 to lower the piston and apply a rotational force to the crank 23, thereby rotating the flywheel 22 and the generator 9 to generate electricity. . Further, Freon and the like exhausted from the exhaust port 8 of the piston mechanism 6 cool through the inside of the double pipe 11 connected thereto. Thereafter, the oil is introduced into the oil separator 12 to separate the oil that has melted from the piston mechanism 6, and the oil is returned from the automatic return valve 13 through the return pipe 14 into the piston mechanism 6. Is liquefied by the compressor 16 and the receiver 17
Pressure regulating valve 19 which is stored in the evaporator 4 and is operated by the pressure in the evaporator 4
Controls the amount of Freon and the like supplied to the evaporator 4. Freon and the like not supplied from the evaporation pressure regulating valve 19 are returned to the intake port of the compressor 16 through the liquid return pipe 21. The piston mechanism 6 is a valve mechanism that opens and closes with a cam interlocked with the crank 23 to move the piston up and down,
3 and a flywheel 22 attached thereto are provided with a rotational force, and the generator 9 connected thereto generates electric power and uses it as electric power.

[0007]

Since the present invention is configured as described above, it produces the following effects. B) The piston mechanism 6 can be easily rotated by the vapor pressure of Freon or the like by the heat collected by the heat collecting panel 1 to easily generate power at a low cost. B) Since it can be made compact, it can be used as a household power generator. C) Clean energy can be obtained by using solar heat. D) The heating pipe 5 in the evaporator 234 heats the chlorofluorocarbon and the like to increase the vapor pressure and at the same time cools the hot water by the heat of vaporization of the chlorofluorocarbon and the like, thereby cooling the respective parts and the chlorofluorocarbon and the like to thereby cool the compressor 16. To assist liquefaction at E) Cooling can be performed by passing cold water through the double pipe 11 attached after the exhaust port 8 and passing fluorocarbon or the like through the inside, thereby facilitating liquefaction. F) By providing the heat storage tank 2 after the heat collecting panel 1, the heat storage tank 2 can be used as a heat source for other floor heating or hot water supply.
