Foldable trimaran side sheet

Abstract

The invention relates to a foldable trimaran side sheet. The foldable trimaran side sheet is composed of a sheet body, a first connecting rod, a second connecting rod, a third connecting rod, a fourth connecting rod, a first rotation pair, a second rotation pair, a third rotation pair and a fourth rotation pair; the sheet body is hollow and streamlined in appearance, and the cross section outline of the sheet body is in the shape of a deep V; self-locking devices are arranged in the first rotation pair, the second rotation pair, the third rotation pair and the fourth rotation pair, and when the connecting rods rotate to the needed angles, the connecting rods can be locked in the states by the self-locking devices; through telescoping and folding of the four connecting rods, the foldable trimaran side sheet can achieve three working states including the stretching state, the contracting state and the V-shaped state. According to the foldable trimaran side sheet, the speed controllability and the maneuverability of a trimaran are effectively improved; the structure is simple, use is convenient, the foldable trimaran side sheet can be applied to ship braking, emergency collision preventing among ships and port entering and exiting and anchoring of the trimaran, and the very important significance for the ship transportation safety and ship maneuverability is achieved.

Description

technical field [0001] The invention relates to a trimaran side panel, in particular to a foldable trimaran side panel. Background technique [0002] The trimaran is mainly composed of three hulls, the middle of which is the main hull, which accounts for about 90% of the displacement volume, and there is a side hull of the same size on both sides. The main function of the hull is to improve the stability and stability of the ship. Seakeeping. The main characteristics of the trimaran are that the medium and high speed resistance performance is better than that of the monohull and catamaran, the seaworthiness is better than that of the monohull, and the stability is better. However, the trimaran also has many disadvantages. Its structure is complicated, its weight is heavy, its design is difficult, its maneuverability is slightly poor, and its large width makes anchoring and docking more difficult. [0003] In order to pursue the rapidity and high efficiency of the ship, we ...

AI Technical Summary

Problems solved by technology

The parking stroke of the trimaran is also very large, and the parking time is long, which is not conducive to ship maneuvering and emergency collision avoidance

The time required for the reverse braking method is very long, which makes the yaw amount and yaw angle of the ship during the deceleration process larger; It is necessary to reverse the brake to stop the ship at last; the operation of dragging the anchor is complicated, and it is only suitable for smaller ships of 10,000 tons and below
