Retractable fin stabilizer device retractable and stop mechanism

Abstract

The invention relates to a receiving and stopping mechanism for rear-receiving type fin stabilizer device. At least one receiving oil cylinder is arranged in a receiving mechanism, the receiving oil cylinders are hinged to an oil cylinder mounting seat through rotating shafts, the front ends of piston rods of the receiving oil cylinders are connected with a cantilever mechanism of a rotary disk through oil cylinder lug rings and first rotating pins, the rotary disk is driven by the receiving oil cylinders to rotate, and the rotary disk is rotated to the fin releasing position or the fin receiving position; and at least one stopping plate is arranged in a stopping mechanism, the stopping plates are hinged into a stopping mechanism base through stopping plate rotating pins, the upper ends ofthe rear ends of the stopping plates are hinged with piston rods of stopping oil cylinders through stopping oil cylinder rotation pins, the stopping oil cylinders are connected to the stopping mechanism base through stopping oil cylinder hinge bases, and the stopping plates are driven by the stopping oil cylinders to overturn to be used for stopping rotation of the rotary disk or motion of the receiving oil cylinders. The receiving and stopping mechanism is compact and simple in structure; and compared with a current receiving and stopping mechanism, the weight is reduced by 35%. The receiving angle of the device can be changed by designing different retracting oil cylinder strokes.

Description

technical field [0001] The invention relates to a device for reducing rolling motion of a boat, in particular to a retractable fin stabilizer. Background technique [0002] Fin stabilizers have become an important equipment for ships with higher speeds to reduce roll and improve navigation performance. There are various forms of fin stabilizers, which can be summarized into two categories, namely, non-retractable and retractable. And the retractable type is the main type, and the retractable type includes folding type, telescopic type and semi-telescopic type. Among them, the folding type is developing rapidly. The previous folding type stabilizers are mostly front-retractable structures, but due to the rear-retractable The structure has the advantages of reduced sailing resistance, high fin efficiency, fins can be arranged on better parts of the ship's hull streamline to improve the anti-rolling effect, low maintenance cost, and small fin box size.

Problems solved by technology

At present, the retractable fin stabilizer and the locking mechanism of the rear-retractable fin stabilizer adopt non-standard design, the structure is complex, the parts are processed with high precision, the assembly is difficult, the manufacturing cycle is long, and the economy is relatively poor, so it is not suitable for promotion to low-cost products. use on device
