Hatch cover mechanism suitable for full-electric propulsion bulk cargo ship

Abstract

The invention provides a hatch cover mechanism suitable for a full-electric propulsion bulk cargo ship and relates to the field of kiloton-grade full-electric propulsion bulk cargo ships. The hatch cover mechanism suitable for the full-electric propulsion bulk cargo ship is located on a main deck, comprises a hatch cover and further comprises motors located at the head end and the tail end of thehatch cover and providing operation power for the hatch cover mechanism, traction devices located on the left side and the right side of the hatch cover and driving the hatch cover to move towards thehead or the tail, at least four sets of idler wheel components bearing the bottom of the hatch cover, a track component located below the idler wheel components and making the hatch cover to be borneby the idler wheel components and move towards the head or the tail along the track component under the effect of the traction devices, and a control system electrically connected with the traction devices and used for controlling the traction devices to be started or stopped. The electric power effect is adopted in the whole motion process, fuel and the like are not used as power, pollution of waste emission does not exist, the hatch cover mechanism is a clean measure to achieve hatch cover motion, and the traction devices are remotely controlled through the control system to be started or not.

Description

technical field [0001] This patent relates to the field of thousand-ton all-electric propulsion bulk carrier, specifically, a hatch cover mechanism suitable for all-electric propulsion bulk carrier. Background technique [0002] For small bulk carriers of the thousand-ton class, the hatch covers of cargo holds are often covered with soft materials such as tarpaulins, and fastened with specific marine straps on both sides. Opening the straps requires a lot of work and takes a long time; for large bulk carriers of the 10,000-ton class, the hatch cover of the cargo hold often adopts a side-moving hatch cover, and a cargo hatch is composed of one or two covers. When the hatch cover needs to be opened or closed, the oil hydraulic device arranged on the deck drives the hatch cover to move horizontally to both sides to realize the opening or closing of the hatch cover, but this method needs to use fuel oil as power. With the development of the shipbuilding industry, it is the gene...

Problems solved by technology

[0002] For small bulk carriers of the thousand-ton class, the hatch covers of cargo holds are often covered with soft materials such as tarpaulins, and fastened with specific marine straps on both sides. Opening the straps requires a lot of work and takes a long time; for large bulk carriers of the 10,000-ton class, the hatch cover of the cargo hold often adopts a side-moving hatch cover, and a cargo hatch is composed of one or two covers. When it is necessary to open or close the hatch cover, the oil hydraulic device set on the deck drives the hatch cover to move horizontally to both sides to realize the opening or closing of the hatch cover, but this method needs to use fuel oil as power

With the development of the shipbuilding industry, it is the general trend to seek clean energy. Therefore, the traditional side-moving hatch cover powered by fuel oil will not meet the requirements of environmental protection. We urgently need a green and environmentally friendly hatch cover mechanism. Replace the existing oil-hydraulic drive
