Title:
FLOATING FLAP GATE
Document Type and Number:
WIPO Patent Application WO/2014/097712
Kind Code:
A1
Abstract:
The purpose of the present invention is to enable installation without compromising appearance, even if a housing space cannot be ensured in a side doorstop interior; the housing space is for housing a system for tracking water levels at the time of assisting the erection of a door, absorbing shock at the completion of the erection, and the door being dropped. The present invention is a floating flap gate (21) which is disposed at an opening or entry/exit of a breakwater or flood barrier, and with which a distal end side (22b) of a door (22) is configured so as to be able to be erected and rotated about a rotating shaft (22c) of a proximal end side (22a). A water level tracking mechanism (26) tracks water levels at the time of assisting the erection of a door, absorbing shock at the completion of the erection, and the door being dropped, and is provided with fixed pulleys (26b, 26c) that guide a wire rope (24) one end of which is attached to a distal end surface (22d) of the door (22) and to the other end of which a counterweight (26a) is attached, and that are installed so that the counterweight (26a) is at the lowest point when an angle of incline θ of the door (22) reaches a predetermined angle. The water level tracking mechanism is disposed in a housing body (25) that is provided to a position corresponding to the wire rope (24) attachment section of the distal end surface (22d) of the door (22) in a dropped state.
