A water intake screen with a filter panel includes a frame adapted to be
connected to the water intake and a circular filter panel disposed
transversely in an opening of the frame, to which it is fastened. The
panel includes a wheel extending in a substantially vertical plane
between a lower position and an upper position and having radial
retaining members on the upstream side of the panel and attached thereto,
an aspiration device on the upstream side of the retaining members, and
elements for driving the panel and/or aspiration device with a rotary
relative movement so as to generate locally through the panel a
successive counterflow at each retaining member in accordance with the
rotary relative movement in order to take up successively debris and
particles retained thereby and to direct them through an evacuation pipe
adapted to evacuate the debris and particles to the exterior.
