DISH TYPE SOLAR HEAT POWER GENERATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a dish type solar heat power generation system in which a stirling engine is not influenced by a motion of a reflection mirror, but always kept in its vertical direction and even if a positional relation between a high temperature side of the stirling engine and the reflection mirror is changed, solar light collected by the reflection mirror can be efficiently irradiated against a light receiving part of the stirling engine and restricting a reduction of a power generating efficiency.SOLUTION: This invention relates to a dish type solar heat power generation device comprising a dish type reflection mirror having a circular surface shape or a parabolic surface shape and a solar heat power generator unit for generating power by solar light collected by the reflection mirror. The solar heat power generator unit comprises a stirling engine operated under a temperature difference between its low temperature part and its high temperature part; an alternator for generating power through operation of the stirling engine; a light receiving part arranged to be contacted with the high temperature part of the stirling engine; and a vertical orientation keeping mechanism for keeping the solar heat power generator in a vertical direction. The solar heat power generator unit is rotatably attached to a frame for the solar heat power generator unit arranged at the reflection mirror in such a way that the light receiving part is installed at the light collecting position of the reflection mirror.SELECTED DRAWING: Figure 1
