Electric drive fin stabilizer

Technical field

The invention belongs to stabilizer technical field, particularly a kind of electric drive fin stabilizer.

Background technology

Fin stabilizer be reduce boats and ships under sail rolling be a kind of special equipment that object is equipped, generally, drive fin stabilizer to adopt hydraulic oil cylinder driving more, its control system mostly is electrohydraulic servo-controlling system, but because Hydraulic Elements are higher to requirement on machining accuracy, and complete machine structure complexity, bulky, cause its cost compare high, electrohydraulic servo-controlling system is had relatively high expectations to working environment in addition, need avoid hydraulic oil to be polluted, and maintenance, debug difficulties.

Therefore and be not suitable for the fin stabilizer that installation volume is huge, structure is heavy minitype ship is due to its small volume, and displacement is less.In recent years, along with the development of electron and electrician technology and electrical motor manufacturing technology, greatly reduce the cost of electro-servo control system, the advantage of electric drive fin stabilizer is highlighted.

Summary of the invention

The object of the present invention is to provide and a kind ofly can overcome the deficiency that uses electrohydraulic servo-controlling system in fin stabilizer, reduce the volume of fin stabilizer, make the cost of fin stabilizer, improved the speed of response of system and the electric drive fin stabilizer of control accuracy.

The technical solution that realizes the object of the invention is:

A kind of electric drive fin stabilizer, comprises fin case, permagnetic synchronous motor, retarder, stabilizer, frequency converter, controller, fin axle; The outer ledge of fin case is by being fixedly welded on hull; Fin case outside has fin case mouth, and fin axle, through this fin case mouth, forms a pair of revolute pair between fin axle and fin case mouth; Between fin axle and fin case mouth, sealing arrangement is installed; The input end of retarder is connected by key with permagnetic synchronous motor mouth, and the mouth of retarder is connected by key with fin axle, and fin the tip of the axis and stabilizer are connected; Permagnetic synchronous motor, retarder are all fixed in fin case; Frequency converter connects three phase mains, and a side is connected with controller, and opposite side is connected with permagnetic synchronous motor.

The present invention compared with prior art, its remarkable advantage:

(1) electric drive fin stabilizer provided by the present invention, its control system is electro-servo control system, this faster system response, control accuracy is high.

(2) the electro-servo control system of electric drive fin stabilizer of the present invention is simple in structure, has saved the space of ships and light boats, is particularly suitable for being installed on the ships and light boats that displacement is little.

(3) electric drive fin stabilizer of the present invention needn't be equipped with special hydraulic oil source again, has avoided oil liquid leakage, and therefore cleanliness level is higher, is particularly suitable for the use of luxury yacht.

(4) electrical equipment that electric drive fin stabilizer of the present invention adopts has more universal, thereby has improved the reliability and maintainability of system.

Below in conjunction with accompanying drawing, the present invention is described in further detail.

The power that permagnetic synchronous motor 2 produces converts by retarder 3, and the dynamic action after conversion subtracts and shakes on stabilizer 4.

Implementation process:

Be installed on the roll angle of the roll angle sensor detection hull on hull, controller 6 is according to the corner of this roll angle signal control permagnetic synchronous motor 2, permagnetic synchronous motor 2 drives stabilizer 4 to rotate corresponding corner, and this process is consistent with the fin angle control method of the stabilizer of existing electro-hydraulic servo control.
