Floating dock for locally repairing ship bottom

Abstract

The invention discloses a floating dock for locally repairing a ship bottom. The floating dock comprises an underwater part, an overwater part, and sealing drainage mechanism. The underwater part comprises an operation cabin with an upward opening, and the opening of the operation cabin is in sealed contact with the ship bottom of a ship to be repaired; the overwater part is connected with one endof the underwater part and extends upwards, the overwater part is located above the liquid level, the overwater part comprises a cab and a maintenance personnel room, and the maintenance personnel room is provided with a personnel pipeline communicated with the operation cabin; the sealing drainage mechanism comprises a circle of waterproof pad arranged on the edge of the opening of the operationcabin, the waterproof pad protrudes upwards, a circle of water falling groove not communicated with the operation cabin is further formed in the inner circle of the waterproof pad, an opening of thewater falling groove is upward, and the bottom of the water falling groove is communicated with the outside through a drainage pipe connected with a water pump. The floating dock is small in overall tonnage and low in cost, a waterproof operation cabin cavity can be locally formed in the bottom of a ship to be repaired, personnel can conveniently contain the marine operation cabin and carry out maintenance, and the operation cabin has a waterproof and drainage dual structure and avoids water seepage.

Description

technical field [0001] The invention relates to the field of shipping, in particular to a floating dock for partial repair of the bottom of a ship. Background technique [0002] The bottom of the ship is vulnerable to damage, such as impact, which may damage the steel structure or coating of the bottom of the ship, and requires certain repairs. The general repair method is to use a dock, which is divided into a dry dock and a floating dock. Dock repairs are time-consuming and labor-intensive, but the results are good. Another repair method is to use the bottom robot or diver to repair, this repair method is suitable for small repair operations. However, for the state to be repaired between the two repair methods, it is difficult to repair by using bottom robots and divers, and the relative economic efficiency is not good if the overall dock is used. Contents of the invention [0003] The problem to be solved by the present invention is to provide a floating dock for par...
