Description

Crane structure and ship

Technical Field

The invention relates to the technical field of ships, in particular to a crane structure and a ship.

Background

With the development of shipping technology, the role of ship transportation in international trade is becoming increasingly important. However, huge energy consumption during the sailing of ships causes a series of environmental pollution problems with increased carbon emissions. In order to reduce carbon emission and control environmental pollution, reasonable application means of clean energy technology are needed to be researched for transportation ships. In recent years, wind energy has been used as a clean energy source on ships, and the main application mode is to arrange a rotary drum sail on the ship, and the magnus effect is utilized to enable the ship to obtain an energy-saving effect.

In particular, the rotor sail is generally a cylinder rotating about an axis, the device being mounted vertically on the deck of the vessel. When the ship sails, when the rotating cylinder receives the effect of lateral wind force, the wind speed flowing through the surface of the rotating cylinder can be different, and then pressure difference, namely magnus effect stress, is formed on two sides of the rotating cylinder. The occurrence of this force may assist the vessel in obtaining additional thrust, thereby reducing the power demand on the vessel power plant and thus producing an energy saving effect.

Although the rotary drum sail has been used to some extent on ships, the rotary drum sail device itself is a bulky structure which, when installed on a ship, has the following drawbacks:

1. the occupied deck area affects the effective utilization of the deck space;

2. interference with a crane on the deck for lifting cargo, in order to avoid such interference, the rotary drum sail cannot be installed at the most efficient position, reducing the use effect of the rotary drum sail.

3. The crane itself can form the obstacle of driving sight, adds the barrier of driving sight after setting up the rotary drum sail and further increases, and too many barriers can influence safe driving.

Therefore, a crane structure and a ship are needed to solve the above technical problems.
