START MEANS INSTALLED SOLAR HEAT DRIVE STIRLING ENGINE

摘要

PURPOSE: A solar energy-driven stirling engine having a start unit is provided to quickly start the engine even if it is repetitively stopped by weather conditions, thereby improving efficiency in generating power. CONSTITUTION: A solar energy-driven stirling engine (1) having a start unit (12) includes a temperature sensor (10), an actuation detecting sensor (11), the start unit, and a control part (13). The temperature sensor at the edge of a solar collecting panel (9) measures the temperature of the solar collecting panel at the heating cylinder of the stirling engine. The actuation detecting sensor comprises an inductive body (11a) and an inductive sensor (11b). The inductive body is fixed to a driving wheel, and the inductive sensor is fixed to a frame. The start unit includes a driven gear (12b), a driving gear (12c), and an idle gear (12e). The driven gear is fixed to the driving wheel. The driving gear is coupled to the driving shaft of a start motor (12a) fixed to a base panel (16) on which the stirling engine is installed. The idle gear is actuated by a solenoid (12d) on the base panel, and switches power for the driven gear and the driving gear. The control part firstly detects the operational condition of the actuation detecting sensor when the temperature of the temperature sensor rises, and feeds power to the start unit when the actuation of the actuation detecting sensor does not exist in order to rotate the driving wheel with the driving force of the start motor.
