Description

technical field [0001] The invention relates to the technical field of ships, in particular to a hatch cover. Background technique [0002] Cargo ships are important means of cargo transportation on water, generally including bulk carriers, tankers, general cargo ships and container ships. Among them, the bulk carrier is a kind of cargo specially used to transport unpacked goods, such as coal, ore, timber, livestock, grain, etc. [0003] The coal cargo holds of existing bulk carriers are generally not equipped with hatch covers. However, during the voyage of the cargo ship, the cargo tanks will be flooded due to splashing waves or rain. The coal cargo tanks need to be equipped with large-capacity bilge pumps to move The water inside is pumped out in time. In addition, during the loading and voyage of cargo ships, the coal dust is easily blown up by the wind. On the one hand, it causes the loss of coal in the cargo hold, and on the other hand, the coal dust pollutes the sur...

Problems solved by technology

[0003] The coal cargo holds of existing bulk carriers are generally not equipped with hatch covers. However, during the voyage of the cargo ship, the cargo tanks will be flooded due to splashing waves or rain. The coal cargo tanks need to be equipped with large-capacity bilge pumps to move The water inside is pumped out in time

In addition, during the loading and voyage of the cargo ship, the coal dust is easily blown by the wind. On the one hand, it causes the loss of coal in the cargo hold, and on the other hand, the coal dust pollutes the surrounding environment.

[0004] Some coal cargo holds cover the cargo hold with canvas. Although this can play the role of keeping out the rain, the canvas cover needs to be removed when unloading, and the coal cargo hold is large in size and inconvenient to operate. Many people cooperate to complete
