Automatic swimming pool or reservoir covering device for e.g. avoiding deposit of leaves, has charging unit charging batteries through solar energy by regulating charging voltage delivered to batteries and by avoiding discharge of batteries

摘要

The device has an apron (2) with a juxtaposition of sheets (3) articulated with each other and moving from an unwinding position for covering a swimming pool towards a winding position around a winding shaft (4), by an electric motorization unit (5) supplied by batteries (6). A charging unit charges the batteries through solar energy by regulating a charging voltage delivered to the batteries and by avoiding discharge of the batteries.
