) is a conventional Stirling engine-driven power generator. In FIG. 2, 1 is a concentrating device that focuses incident sunlight P on one point, 2 is an elevation adjustment device that supports the condensing device 1 and changes the elevation angle of the condensing device, and 3 is a driving device 2. The installed rotary table, 4 is a rotation angle adjusting device for driving the rotary table 3, 5 is a heater disposed at the condensing point of the light condensing device 1, and 6 is a heater 5 heated by the concentrated sunlight P. 7 is a power generation device driven by the Stirling engine 6. The Stirling engine 6 is attached to a support frame 8 integral with the light condensing device 1 so as to be located at a light condensing point, and a power generation device 7 is attached to this Stirling engine 6.

Next, the operation of the above-mentioned conventional device will be explained. The sunlight P that has entered the condensing device 1 is reflected by the reflective surface 1a and heats the heater 5 at the condensing point. Therefore, the Stirling engine 6 operates using the heater 5 as a heat source to drive the power generation device 7. On the other hand, the elevation adjustment device 2 transmits the rotational force of the drive source 2a to a shaft 9 protruding from the side surface of the condensing device 1 via the power transmission member 2b, and rotates it in the direction of the arrow via this shaft 9. . Further, the rotation angle adjustment device 4 transmits the rotational force of the drive source 4a to the shaft 3a of the rotary table 3 via gears G1 and G2, and rotates the rotary table 3 in the direction of the arrow via this shaft 3a. Thereby, the condensing device 1 is made to track the direction in which the sun is located, and sunlight P is efficiently condensed.

[Problems to be Solved by the Invention] Since the conventional Stirling engine-driven power generation device is constructed as described above, in order to adjust the elevation angle of the condenser 1 on which the Stirling engine 6 and the power generation device 7 are mounted, a large Requires driving force,
The elevation adjustment device 2 becomes larger. Further, when the Stirling engine 6 or the power generating device 7 breaks down, it becomes necessary to remove it from the condensing device 1 in order to perform work safely and easily, resulting in problems such as requiring a lot of time and money for maintenance work.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a Stirling engine-driven power generation device that can reduce the driving force of a condensing device and is easy to maintain.

[Means for Solving the Problems] A Stirling engine-driven power generation device according to the present invention includes a Stirling engine and a power generation device mounted on a common rotary table together with an elevation adjustment device that supports a concentrator and changes the elevation angle of the concentrator. This is the installed configuration.

[0007]

[Function] In the Stirling engine-driven power generation device according to the present invention, the Stirling engine and the power generation device are mounted on a rotary table, so the light condensing device can be lightened, and the elevation angle that supports this condensing device and changes the elevation angle. The regulating device can reduce the driving force. Furthermore, when the Stirling engine or power generation device breaks down, maintenance work can be performed safely and easily on the rotary table.
