Device arranged in swimming pool and used for reducing ship rolling, and control method thereof

Abstract

The embodiment of the invention discloses a device arranged in a swimming pool and used for reducing ship rolling, and a control method thereof. The device comprises: a platform which is arranged on the lower portion of the bottom face of the swimming pool and can be driven by a lifting driving device to ascend and descend. a plurality of stand columns which are sequentially arranged on the platform in the width direction of the ship, wherein each stand column comprises a base arranged on the platform and a blade rotationally connected with the base through a rotating shaft, each blade comprises a rotatable part and a fixed part, and when the platform rises to the top, the lower edge of each rotatable part is higher than the bottom surface of the swimming pool, and when the platform lowersto the bottom, the upper edge of the rotatable part is flush with the upper surface of the bottom of the swimming pool, and a sealing part is arranged between the bottom of the swimming pool and theblades; and a control system in communication connection with the communication system and used for acquiring the rolling angle and the rolling period, analyzing to obtain the rotating angle and controlling the rotatable parts to rotate to the rotating angle when the platform is lifted to the top so as to adjust the area of a channel formed among the rotatable parts of the plurality of blades.

Description

technical field [0001] The invention relates to the technical field of ship anti-rolling, in particular to a device and a control method arranged in a swimming pool for reducing ship rolling. Background technique [0002] In order to improve the quality of life of passengers and crew, swimming pools are installed on many ships; especially large cruise ships generally have several swimming pools. Since the water surface of the swimming pool is open, a free liquid surface is formed, which reduces the stability of the ship. When a ship encounters severe sea conditions, the ship will roll, and the water in the swimming pool will also shake with the ship's roll, which will cause the ship's roll to intensify, and even seriously affect the safety of the ship. [0003] In the prior art, if there is a big storm and sea conditions, it is possible to discharge all the swimming pool water into the sea or other water tanks. However, due to the large number of swimming pools and the lar...

AI Technical Summary

Problems solved by technology

In terms of economy, the water in the swimming pool is fresh water, which is generally supplied by the shore or produced by a water generator, and the cost is very high. If it is discharged into the sea in the event of a strong storm, it will cause a lot of waste

Some ships install special anti-rolling water tanks to reduce ship roll, but this is not suitable for cruise ships, because the internal space of cruise ships is very precious, and special anti-rolling water tanks are rarely installed
