Abstract
The device (100) serves to separate solid particles from the water of a flow (E) feeding a hydraulic machine of the turbine, pump, or turbine-pump type. The device has flow inlet and outlet zones (104, 105) for the flow that are spaced apart along an advance axis (X100) of flow advance through the device (100). The device (100) comprises a plurality of ducts (110) placed in parallel, each having a mouth and a downstream end between the inlet zone (104) and the outlet zone (105). In section perpendicular to the advance axis (X100), each duct presents a section in the form of a spiral with a radius of curvature that increases from the mouth towards the downstream end or from the downstream end towards the mouth, with each duct (110) presenting a thickness measured in a generally radial direction relative to the advance axis that is less than 10% of the width (l110) of said duct, measured parallel to said axis (X100).
