Electric hatch cover of 40000-ton self-unloading ship cargo hold

Abstract

The invention discloses an electric hatch cover of a 40000-ton self-unloading ship cargo hold. Sealing pieces are arranged on the periphery of a cargo hold opening, the hatch cover comprises two moving units arranged on the cargo hold opening, each moving unit comprises a cover plate matched with the cargo hold opening and an opening mechanism driving the cover plate to move, guide plates are arranged on the two sides of the cargo hold opening, and the cover plates are arranged on the two guide plates. According to the 40000-ton self-unloading ship cargo hold electric hatch cover, the cargo hold can be rapidly opened through cooperation of the guide plate and the opening mechanism, and rapid butt joint closing of the cover plate can be achieved through the lifting part. Through cooperationof the cargo hold opening and the butt joint part, sealing of the cover plate and the cargo hold opening can be achieved, seawater is prevented from seeping from a butt joint seam of the cover plateand the cargo hold opening, and the water tightness of the hatch cover is improved. Through the design of the rain baffles, the sawteeth on the rain baffles and the water guide grooves in the rain baffles, rainwater is rapidly guided to leave the rain baffles, rainwater seeping into a butt joint between the two rain baffles is blocked and guided, and the water tightness of the hatch cover is further improved.

Description

technical field [0001] The invention relates to the field of ships, in particular to an electric hatch cover for a cargo hold of a 40,000-ton self-unloading ship. Background technique [0002] The cover plate is a closed device to ensure the watertightness of the hull and the safety of the cargo in the cabin, and it also has a certain ability to resist pressure. The degree of mechanization and automation of hatch cover opening and closing is directly related to the labor intensity of personnel, the loading and unloading production efficiency of ships and the berthing time in port. The watertightness, strength and reliability of the hatch cover are related to the quality of cargo transportation and the safety of the ship. However, existing ships generally use assembled hatch covers and folding hatch covers. The opening and closing of assembled hatch covers requires hoisting, which takes a long time and has low loading and unloading efficiency. However, folding hatch covers a...

AI Technical Summary

Problems solved by technology

However, existing ships generally use assembled hatch covers and folding hatch covers. The opening and closing of assembled hatch covers requires hoisting, which takes a long time and has low loading and unloading efficiency. However, folding hatch covers are divided into multiple sections, so watertightness is difficult to guarantee.
