AI Technical Summary

Problems solved by technology

It will reduce the lift of the fin stabilizer and increase the resistance. The higher the vortex velocity will cause the liquid to cavitate and cause noise and erosion on the fin surface, affecting the anti-roll effect and navigation safety

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] In the figure: 1-rear fin stabilizer, 2-upper fin baffle, 3-lower fin baffle, 4-connecting plate, 5-front of stabilizer fin, 6-fin shaft, 7-trapezoidal tail.

[0017] The invention discloses a detached fin stabilizer, which comprises a fin shaft 6, a front part of the fin stabilizer 5, a rear part of the fin stabilizer 1, an upper fin surface baffle 2, a lower fin surface baffle 3, a connecting plate 4, a trapezoidal Tail 7. The front part 5 of the fin stabilizer with the fin shaft 6 at one end and the rear part 4 of the fin stabilizer are connected together through the connecting plate 4, the fin shaft 6 is connected to the hull, and the upper fin surface baffle 2 is arranged on the free end of the fin stabilizer On the fin surface, the lower fin surface baffle is arranged on the lower fin surface. The present invention proposes a separate fin stabilizer, the...

Abstract

The invention belongs to the technical field of ship navigation, and in particular relates to a separate fin stabilizer, which consists of a fin stabilizer rear, an upper fin surface baffle, a lower fin surface baffle, a connecting plate, a fin stabilizer front, a fin shaft, a trapezoidal The tail part is composed of a fin shaft fixed at one end of the front part of the stabilizer fin, the front part of the stabilizer fin is fixed with the rear part of the fin stabilizer through a connecting plate, and the rear part of the fin stabilizer is fixed with a trapezoidal The tail, the upper surface of the rear of the fin stabilizer and the upper surface of the front of the fin are fixed with an upper fin surface baffle, the lower surface of the rear of the fin stabilizer and the front of the fin stabilizer. The lower fin surface formed by the lower surface of the lower part is fixed with a lower fin surface baffle at one end away from the fin axis. The fin stabilizer designed in the present invention has a certain gap between the front part of the fin stabilizer and the rear part of the fin stabilizer, which can play the role of diversion, reduce the vortex velocity of the wing tip, reduce the drag, increase the lift-to-drag ratio, and improve the anti-rolling effect. Effect.

Description

technical field [0001] The invention belongs to the technical field of ship navigation, and in particular relates to a separate fin stabilizer. Background technique [0002] The rolling of the ship will seriously affect the safety of the ship's navigation and the comfort of the crew. In order to reduce the impact of the ship's rolling, the ship's anti-rolling device has become an indispensable part of the ship's design. Nearly a hundred types have been developed Stabilizers, but fin stabilizers, water tank stabilizers, and bilge keels are widely used, among which fin stabilizers have the best stabilization effect. In 1985, the British ship "Queen Mary" carried out a fin stabilizer performance test under the condition of heavy wind and waves. When the fins are working, the ship's rolling angle is about 2 degrees on average, and when the fins are not working, the rolling angle is 25 degrees. At present, the fin stabilizer has the best stabilization effect of more than 90%. T...
