Abstract
PURPOSE: To vertically move a netting device along the slope of a dam according to the variation of the water level in the netting device by providing a weight through a pulley from the dam as a mooving means for the netting device.
CONSTITUTION: A netting device 1 consists of a float 4 surronding the intake tower of a dam 2 and a dust chekcing net 5 whose lower end is provided with plural weights 5a, provided along the lower side of the float 4. As mooving means 8 for the dam 2, a wire rope 10 extending from the top of the dam 2 is wound around a pulley 9 and a weight 11 is hung down from the lower end of the rope 10. Thus, even when the level of water surface 7 is varied, the netting device 1 is always closed to the dam 2 by the action of the weight 11 in such a way that it can come into contact with the slope 2a of the dam 2 by means of a roller 6, so that no aperture is produced between the netting device 1 and the dam 2.
