Title:
FLOATING BODY TYPE FLAP GATE
Document Type and Number:
WIPO Patent Application WO/2016/174919
Kind Code:
A1
Abstract:
The present invention enables installation of a gate body with a long span when an above-ground structure cannot be disposed in the middle portion in the width direction of the gate body. Provided is a floating body-type flap gate 1 in which, when water is flowing in, a distal end side 2b of a gate body 2 is swingably raised with a rotation shaft 2c of the base end side 2a serving as a fulcrum. One end of a wire rope 4 is affixed to the back surface 2d of the gate body 2 in a fallen state. An underground space 5a is formed at the distal end portion side of the gate body 2 in a storage space 5 that stores the fallen gate body 2, and first and second fixed pulleys 7a, 7b and first and second movable pulleys 8a, 8b are arranged in the underground space 5a. The other end of the wire rope 4 guided via this group of pulleys is affixed at the ceiling part of this underground peace 5a. By the rise and fall of a counterweight 6 to which each second movable pulley 8b is attached, a push-up rod 9 to which each first movable pulley 8a is attached is raised and lowered, whereby the distal-end side of the gate body 2 is pushed up at the initial stage of raising and a sudden drop is inhibited at the final stage of falling, while by the tension acting on the wire rope 4 shock absorption at the final stage of raising and water-level tracking at the initial stage of falling are performed.
