<p>The present invention relates to a system for automatically opening and closing an inner thermal insulation cover of a greenhouse, in which a rear end of an inner thermal insulation cover (50) is fixed on the ground, and a rolling shaft (13) connected to a first motor (12) is installed and fixed on a front end of the inner thermal insulation cover; the rolling shaft rotates normally or reversely as the first motor (12) rotates thereby winding or releasing the inner thermal insulation cover (50) to be opened or closed; a plurality of auxiliary drawing wires (41) and a plurality of main drawing wires (31) aid the rolling shaft (13) in opening or closing the inner thermal insulation cover (50); and the auxiliary drawing wires (41) and the main drawing wires (31) are connected to a driving apparatus via first and second direction switching rollers (42, 43) disposed at an upper portion and a lower portion of an auxiliary drawing wire supporting frame (2), respectively, and a third direction switching roller (36) disposed at a second motor supporting frame (F1). According to the present invention, required components, framework loads of a greenhouse can be minimized, and work efficiency can be enhanced.</p> |
