Abstract
PURPOSE: To eliminate the breakage of an air chamber by water pressure by increasing the buoyancy of an intake pipe by providing an annular air chamber whose lower side is provided with an opening to the upper end periphery of an expansion pipe or the lower side of an intake board.
CONSTITUTION: A funnel-shaped intake board 2 is provided at the upper end of an expansible intake pipe 1, and a float 4 is also provided through a spacer 3 alike. And, an annular air chamber 6 with an opening 5 is provided on the lower side of the intake board 2, and a dust-preventing screen 7 is also provided to the opening 5. When surface water is taken into the intake pipe 1 from between the float 4 and the intake board 2, the float 4 moves in the wake of the change of water level, and the intake pipe 1 expands or shrinks, the buoyance of the intake pipe 1 is increased by the air chamber 6. Also, the same effect can be obtained by providing an air chamber 6' whose lower side is provided with an opening 5' on the upper end periphery of each expansible pipe 1'.
