Apparatus for covering a basin for liquids.

摘要

An apparatus for covering a basin (1) for liquids, for instance basins used for purification of waste water. The apparatus according to the invention comprises a covering element (4), with a regular circumferential shape, so that they can be located adjacent, which covering element floats unto the liquid to be covered. For making the element float a number of floating elements (5) is provided at the lower side of the elements, but these floating elements are not adjacent. Consequently the resulting upward floating force of the floating element keeps the lower side of the covering element on a distance from the surface of the liquid. This distance allows draining or removal of bodies floating on the liquid. Preferably the upper surface (7) of the covering element (4) has the shape of a deepened tray to allow the collection of rain water, so that the elements cannot be blown away.
