Abstract

PROBLEM TO BE SOLVED: To contribute to protection of global environment by converting solar energy directly into a mechanical energy to obtain high efficient power. SOLUTION: High-temperature, high-pressure gas is admitted into a cylinder body 1 having a heating bulb 12 such that a rotating shaft of a crank shaft 5 is connected to a compressor 13, fly wheel 6 and a motor generator 20 for actuation. The high pressure gas discharged from the compressor is guided to the heating bulb 12 and heated to be admitted into the cylinder for driving the piston 3. The exhaust gas is circulated to the compressor via a cooling equipment 16. Sunbeam A is condensed by a converging reflector B so as to be admitted to the heating bulb 12 from a window 12a.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat engine system for preventing pollution of the global environment due to use of fossil fuels and nuclear power, and for generating power by using clean natural energy by solar heat.

[0002]

2. Description of the Related Art Conventionally, there is a solar cell as a technique for directly converting solar energy into electric energy. However, research on solar heat engines such as Stirling engines has been conducted in the technology for directly converting solar energy into mechanical energy.However, satisfactory output cannot be obtained due to low conversion efficiency. Is far from real.

[0003]

SUMMARY OF THE INVENTION The present invention uses a high-pressure gas body as a medium for energy conversion, heats a gas introduced into a heating sphere by condensed solar heat, and utilizes the pressure to produce a gas in a cylinder. It is an object of the present invention to provide an engine system in which the conversion efficiency of a conventional heat engine is increased by driving the piston, and an output for practical use is obtained.

[0004]

In the engine system of the present invention, a compressor, a flywheel and a motor generator for starting are connected to a rotating shaft of a crankshaft by movement of a piston, and a storage battery is connected to the motor generator. . At this time, a motor may be used instead of the motor generator. From the air inlet of the compressor to the heating bulb provided outside the cylinder body via the pressure tank, and from the exhaust pipe of the cylinder to the suction port of the compressor via the cooler. At this time, the exhaust gas may be discharged into the atmosphere except for the cooler. Attach a converging reflector such as a parabolic mirror at the position corresponding to the heating ball outside the cylinder body,
The relationship is maintained so that the reflected light is surely incident on the window of the heating ball. When a spiral tube is used instead of a heating ball, a line focusing method using an ellipsoidal mirror or a hyperboloidal mirror for focusing is adopted.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings (see FIG. 1). A hollow spherical heating ball 12 is arranged,
It is integrated with the cylinder housing 2. Cylinder housing 2
An outflow pipe 12b is provided to connect the heating bulb 12 to the cylinder body.
An exhaust pipe 16 is provided in c, 1d, and the cylinder housing 2. The exhaust pipe 16 is connected to the compressor 13,
In the meantime, the cooler 15 is arranged, and enters the inlet 13a of the compressor 13 via the cooler. Compressor 13
A pressure tank 17 is provided between the air supply port 13b and the heating ball 12.
Are arranged and connected by a pressure tube 19. A piston 3 is combined with the cylinder body 1 and connected to a crankshaft 5 via a piston rod 4. The compressor 13, the flywheel 6, and the motor generator 20 are connected to the crankshaft 5, and the storage battery 2 is connected to the motor generator 20.
1 is connected. A condensing reflector B such as a parabolic mirror is disposed outside the cylinder body 1, and is focused on the window 12 a of the heating ball 12 and fixed at a position related to the cylinder body 1.

Next, the operation will be described. The heating sphere 12 is heated by irradiating the heating sphere 12 with concentrated light from the focusing mirror B.
The starting motor generator 20 is started. The flywheel 6 and the compressor 13 start rotating together with the crankshaft 5. The compressed gas from the compressor 13 enters the pressure tank 17, enters the heating bulb 12 through the pressurizing pipe 19, and heats and expands to increase the flow rate and flow into the cylinder body 1 through the cylinder housing 2. Exhaust gas is exhaust port 1
The air enters the exhaust pipe 16 from c and 1d, passes through the cooler 15, and returns to the compressor 13 from the suction port 13a. This cycle is repeated, and when the gas pressure reaches a predetermined value, the reciprocating solar heat engine continues rotating by itself.

Here, after the engine is started by the motor generator 20, there is also a method of using the motor generator as a generator. When air is used as compressed gas, high-temperature exhaust gas is removed except for the cooler 15. Should be released into the atmosphere.

Next, the function of the plate valves 7a and 7b will be described with reference to FIG. There are inlets 1a and 1b for high-temperature and high-pressure gas on the upper and lower left sides of the cylinder body 1, and outlets 1c and 1d for gas expanded in the cylinder on upper and lower right sides.
When the piston 3 reaches the upper end in the cylinder due to the movement of the piston 3 and the rotation of the crankshaft 5, the cams 11a and 11
By the rotation of b, the plate valve 7a goes up together with the cam roller 9, and the plate valve 7b goes down to open the gas inlet 1a into the cylinder and the gas outlet 1d. When the piston 3 reaches the lower end in the cylinder, the gas inlets 1a and 1d are closed and the gas outlets 1c and 1b are opened by the movement of the plate valves 7a and 7b, and the gas passes through the inlet 1b. The piston 3 is pushed up into the cylinder, and the expanded gas at the top of the piston is discharged from the discharge port 1c.
The pressurized tank 17 is provided with an auxiliary cylinder 22 in order to compensate for the pressure drop caused by the leaked gas, and is not a hollow spherical heating sphere using a parabolic mirror for focusing but an ellipse. For a line hocus in the case of using a plane mirror or a hyperboloid mirror, it is convenient to use a spiral tube 23 instead of a heating ball. [Effects of the Invention] Since the present invention creates mechanical energy by a non-combustion method using solar heat directly, it has an effect of preventing the destruction of the global environment due to emission of carbon dioxide and radioactive contamination.
