Folding anchor for ship

摘要

The anchor has a movable shaft which can be detached from the disc by a bolt to prevent forcible opening of the anchor. The chain (1) runs over a pin (2 or 3), thus pressing the pin in the direction of the disc (4). The bolt is thus pulled out of the disc. The shaft (6) is free to move as far as the fluke stop (7), which is exactly in line with the fluke (8). Other components include a spiral spring (9), linkage (11), linkage or guy wire (12) and fluke guide. When the anchor is opened automatically when run over against the wind, the shaft becomes uncoupled from the disc, and can be lifted out of the sea bed in the opposite direction to the to traction direction without force.
