Outward-folded type marine fin stabilizer

Abstract

The invention relates a marine device, in particular to an improvement of a marine fin stabilizer device. The outward-folded type marine fin stabilizer comprises a ship body, a single end output push and pull hydraulic device and a fin, wherein the single end output push and pull hydraulic device is movably installed on the ship body, one side of the fin is hinged to the ship body, and a connecting rod is installed between the output end of the single end output push and pull hydraulic device and the fin. The outward-folded type marine fin stabilizer has the advantages that the outward-folded type marine fin stabilizer is simple in structure, low in fault rate and convenient to maintain, the fin is freely folded and unfolded, and the unfolding size of the fin is not limited.

Description

technical field [0001] The invention relates to marine equipment, in particular to the improvement of a ship's fin stabilizer. Background technique [0002] When a ship encounters wind and waves during navigation, it will sway. The swaying of the ship will reduce the seaworthiness of the ship, damage the hull structure, affect the normal operation of equipment and instruments, and cause cargo displacement or impact damage. Passengers and crew will be dizzy, and it may affect the combat effectiveness of combat ships. In order to reduce the sway of the ship, many colleagues have conducted in-depth research. At present, the solution with better effect is to install fin stabilizers on the bilge of the ship to control The device outputs a control signal to control the position of the stabilizer fins in the water by measuring the angle of the ship's sway, combined with the ship's speed and other factors.

[0002] When a ship encounters wind and waves during navigation, it will sway. The swaying of the ship will reduce the seaworthiness of the ship, damage the hull structure, affect the normal operation of equipment and instruments, and cause cargo displacement or impact damage. Passengers and crew will be dizzy, and it may affect the combat effectiveness of combat ships. In order to reduce the sway of the ship, many colleagues have conducted in-depth research. At present, the solution with better effect is to install fin stabilizers on the bilge of the ship to control The device outputs a control signal to control the position of the stabilizer fins in the water by measuring the angle of the ship's sway, combined with the ship's speed and other factors

The current fin stabilizers are divided into retractable and non-retractable fin stabilizers. Although the non-retractable fin stabilizer has a simple structure and is easy to manufacture, the span of the fin must be limited within the frame line of the hull. The size is limited, and the retractable fin stabilizer is equipped with retractable single-end output push-pull hydraulic device, fin box, sliding sleeve, retractable connecting rod, guide sleeve, rotator, etc. The retractable marine stabilizer with this structure The rocking fin not only has a complex structure and high cost, but also because there are many parts in the transmission, the wear of multiple parts is accumulated together, and it is easy to generate large accumulated wear, which affects the accuracy of control and is prone to failure. The workload of maintenance is very large. At present, the spanwise size of the fin is not limited, and the marine stabilizer fins with simple structure, small accumulated wear, low failure rate and convenient maintenance are still rare.
