DEVICE FOR DETERMINING THE POSITION OF AN OPENING LEAF OF A SMOKE EXTRACTION SYSTEM AND SMOKE EXTRACTION DEVICE COMPRISING THE SAME

摘要

The device (10) for determining the position of an opening leaf (205) of a system (20) for extracting smoke from a premises, this system comprising: an actuator (210) applying a force to the opening leaf in order to open this opening leaf when this opening leaf is in the closed position, - a cable (215) connecting the opening leaf to a winch (220) positioned inside a housing (225), the winding of the cable on the winch causing the opening leaf to close and a means (230) for turning the winch in order to wind or unwind the cable, the device being characterized in that it comprises: - a sensor (105) of a value of a physical parameter indicative of the movement of the cable, - a detector (1 10) of the position of the opening leaf as a function of the sensed value and a means (115) of securing, outside of the housing, of the device.
