MOORING DEVICE FOR FLAP GATE TYPE BREAKWATER

摘要

The attitude of a mooring hook is intended to be corrected in a short period of time. Disclosed for this purpose is a mooring device (11) for a flap gate type breakwater (1), this mooring device (11) being such that a torque shaft (14) is provided at a position where the same faces a gate mooring section (2d) of a door body (2) in a mooring state. A mooring hook (15) is installed at that position of the torque shaft (14) where the same engages with the gate mooring section (2d). A counterweight (16) is installed which rotates the mooring hook (15) in a direction in which engagement with the gate mooring section (2d) is released. One end of a torque arm (18) is installed on the torque shaft (14). One end of two-way-turning link members (12, 13) is connected to the other end of the torque arm (18), and the other end of the two-way-turning link members (12, 13) is provided in a portion which faces a door body back surface (2c). A rod member (17) comprises, at one end, a vertical rod (17a) which is provided with a slotted hole (17aa) at one end and with a spherical bushing (17ab) at the other end. The other end of the rod member (17) is pulled out to a location above the water surface via the two-way-turning link members (12, 13). The mooring device (11) is provided with a wire member (24) one end of which is connected to the rod member (17) and the other end of which is connected to a coil spring (26) via a pulley (23) that is installed on a hook installation and removal cylinder device (22). Consequently, the attitude of the mooring hook can be corrected in a short period of time.
