Abstract

PURPOSE: To design so that only surface water may be efficiently taken in when the intake of surface water at the lake, swamp, reservoir, etc. is attempted.
CONSTITUTION: The device is composed of float 2 having sharp-pointed body 1 and water basin 5 equipped with intake port 4 linked to intake tube 3. The lower part of the afore-mentioned float 2 has upward-facing tapered surface at taper angle θ1, which is between 5° and 35°. On the other hand, upper surface 7 between the water basin 5 and the intake port 4 has upward-facing tapered surface at taper angle θ2, which is between 5° and 30° and the relation of the two is set at θ1>θ2. With application of intake port designed in this way, intake requirements are met.
