Small waterplane area twin-hull ship

Abstract

The invention relates to a small waterplane area twin-hull ship which is formed by connecting a left sheet body and a right sheet body through a connection bridge, wherein, the left sheet body is formed by connecting a left sponson, a left support and a left submerged body; the right sheet body is formed by connecting a right sponson, a right support and a right submerged body. The small waterplane area twin-hull ship is characterized in that the left submerged body and the right submerged body are respectively provided with a left righting compartment and a right righting compartment which are watertight compartments and are respectively provided with a sea chest; a butterfly valve is installed on the lateral plate of the sea chest, and is connected with a manually operated mechanism. The left submerged body and the right sheet body of the invention are respectively provided with a righting compartment; when the compartment of sheet body at one certain lateral is damaged, the sea water can rapidly enter into the righting compartment at the other side through the sea chest and the butterfly valve, thus righting the catamaran within the range of transverse inclination according to the standards. The small waterplane area twin-hull ship of the invention has simple, light and handy structure, small occupied space and good righting effect, and conforms to standards stipulated by China Classification Society, thus effectively ensuring the safety of the damaged ships.

Description

technical field [0001] The invention relates to a catamaran, in particular to a small waterplane area catamaran provided with a centering device. Background technique [0002] Small waterplane area catamarans have the advantages of good seakeeping and large deck area, and have broad application prospects in scientific research, monitoring, transportation, military and other fields. The small waterplane area catamaran is composed of a left hull and a right hull connected by a connecting bridge, and the left hull and the right hull are respectively connected by a stern, a pillar and a submerged body. Due to the large distance between the two plates, when the sterns, pillars and cabins in the submerged body that constitute the left and right plates are damaged, they are all asymmetrically damaged, and the heeling moment generated after the damage is very large. As a result, the heel angle of the small waterplane area catamaran often exceeds the 7° stipulated in the regulations...

AI Technical Summary

Problems solved by technology

So far, there is no standard for the damage stability of small waterplane area catamarans in my country. At present, the few small waterplane area catamarans that have been built in China basically belong to the series of military auxiliary ships. According to the situation in our country, Military ships may not comply with the requirements of classification societies, so there is no precedent for setting up righting devices on small waterplane area catamarans
