Abstract

A floating cover sheet of a liquid reservoir is configured to rest on the liquid surface and includes a plurality of elongated sheet panels each defining edges and a lower region. The sheet panels are connected to one another and each of the sheet panels has a buoyant carrier sheet disposed in the lower region thereof. The buoyant carrier sheet is made of plastic and defines a carrier surface. A plurality of panel-shaped solar modules are applied to corresponding ones of the carrier surfaces of the carrier sheets. The solar module has a width less than the width of the corresponding sheet panel so as to define, on each sheet panel, a strip of carrier material free of the solar module corresponding thereto and configured to be walked on and to be slip resistant.

Description

BRIEF DESCRIPTION OF THE DRAWING

(1) The invention will now be described with reference to the single FIGURE of the drawing (FIG. 1) which shows a cover sheet of a liquid reservoir.

DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION

(2) FIG. 1 shows a cover sheet 1 of a drinking water reservoir 2, which is made up of individual elongate sheet panels 3 that are connected to one another at the edges.

(3) Each sheet panel has lying underneath a buoyant carrier sheet 4 of plastic.

(4) The surface of the carrier sheet 4 that is opposite from the surface of the liquid and facing outward is covered by a sheet laminate 5 of an elongate form, in the form of a panel, which comprises a layer of thin-film photovoltaic cells, with multiple layers of transparent plastic on their outer side.

(5) The width of the sheet laminate is smaller in relation to the width of the sheet panel and is formed such that a strip 6 of carrier material that is not covered by the sheet laminate, can be walked on and is slip resistant is formed on each sheet panel. Here, the width of the sheet laminate 5 corresponds approximately to half the width of a sheet panel.

(6) The cover sheet is firmly connected at its edges to the delimiting walls of the liquid reservoir and, for reinforcement, has strengthening supports that are not shown any more specifically here.

(7) Each two sheet panels lying next to one another are connected to one another after being turned by 180° about their vertical axis, which extends perpendicularly in relation to the surface of the liquid, such that the strips of carrier material that can be walked on butt against one another, and so a widened “tread strip”, that is, a widened tread area 7, is produced.

(8) It is understood that the foregoing description is that of the preferred embodiments of the invention and that various changes and modifications may be made thereto without departing from the spirit and scope of the invention as defined in the appended claims.
