Composite triple-hulled vessel

Abstract

The invention discloses a composite triple-hulled vessel. The vessel comprises a main hull, side hulls and connecting bridges, wherein the side hulls are positioned on two sides of the main hull; the connecting bridges are connected with the main hull and the side hulls; the lower side of the side hulls is connected with a horizontal fin through an upright support. The composite triple-hulled vessel is also provided with a side hull moving device; the side hull moving device comprises a speed-down transmission mechanism, a connecting bridge moving mechanism and a locking mechanism; the side hull moving device is arranged on the lower side of the connecting bridges and in the cabin of the main hull respectively; the middle part of the connecting bridges is fixedly connected with the upper part of the speed-down transmission mechanism, the upper part of the connecting bridge transmission mechanism and the upper part of the locking mechanism respectively through a support A, a support B and a support C which are transversely arranged on the connecting bridges; the lower part of the speed-down transmission mechanism, the lower part of the connecting bridge moving mechanism and the lower part of the locking mechanism are fixedly connected with the middle part of the cabin of the main hull. The ship resistance of the vessel can be reduced in high speed sailing thus increasing the speed of the triple-hulled vessel .The composite triple-hulled vessel can select an optimal position for the side hulls under actual sea condition and sailing speed so as to improving the sailing stability of the triple-hulled vessel.

Description

technical field [0001] The invention relates to a trimaran with side hulls on both sides of a main hull, in particular to a trimaran with side hulls that can move forward and backward, and belongs to the technical field of ships. Background technique [0002] The trimaran has the advantages of large deck area, relatively low functional requirements during high-speed navigation, and more versatile mechanical devices. When the ship sails in different sea areas, in order to ensure the speed and stability of its sailing, it is necessary to reduce the resistance suffered by the trimaran. Adding horizontal wings to the lower part of the side hull can significantly reduce the resistance suffered by the trimaran and increase its sailing speed. [0003] The date of application is April 13, 1993, and the announcement number is CN2163791, which discloses the Chinese utility model patent of "three-body wave-suppressing planing boat". , the deck is approximately rectangular, the slidin...

Problems solved by technology

However, the adaptability is not strong, and the position of the side hull cannot be adjusted independently according to the weather conditions in the water area. At the same time, the speed of the trimaran needs to be improved.
