ていることを特徴とする可動堰。 A weir plate pivotally supported in a waterway so that it can be tipped over by water pressure, a tension wire that supports the weir plate so that it cannot fall over, and a wire winding mechanism that irreversibly winds up the wire to raise the weir plate. and an overturn prevention release mechanism that automatically releases the reverse stop of the wire rod winding mechanism and overturns the weir plate due to a rise in water level on the upstream side of the weir plate. The wire winding mechanism includes a drive shaft that rotates a winding drum, a ratchet wheel fixed to the drive shaft, and a ratchet wheel that is engaged with the ratchet wheel so that the drive shaft rotates only in the winding direction. The fall prevention release mechanism includes a slide member that supports the ratchet claw and is slidable in a direction substantially perpendicular to the drive shaft, and a roller supported by the slide member. a cam that is brought into contact with the roller and controls the ratchet pawl to take a first position where it engages with the ratchet wheel and a position where it separates from the ratchet wheel; a float that is raised as the water level rises; The float is characterized by being configured to include a weight that falls freely as the float rises, and a cam operating means that operates the cam so that the cam assumes the second position due to the falling impact of the weight. A movable weir.
