Description
Technical field
The present invention relates to a kind of equipment for reducing ships and light boats rolling motion, particularly a kind of fin stabilizer at zero speed belongs to
Stabilizer executing agency technical field.
Background technology
Existing fin stabilizer can provide a variety of subtract for various ship and shake allocation plan, technology relative maturity, it is ensured that ship
Only there is the good demand of shaking that subtracts under the medium/high speed of a ship or plane, but recent years are needed to subtracting to shake under the low speed of a ship or plane even zero power test with ship
Ask increasingly urgent, therefore, domestic-developed tank stabilizer and the united integrated value method system of stabilizer, i.e., using subtracting under zero power test
Shake water tank and subtract and shake, using tank stabilizer and stabilizer combined stabilization under the medium/high speed of a ship or plane, but need to design, install, safeguards two sets it is only
Erect standby, economy is not good enough, and take space in larger cabin, increase full marine railway water, influence ship resistance.
External Duo Jia fin stabilizer at zero speed producer makes it possess full boat using being improved on the basis of existing stabilizer mostly
The solution of fast stabilization capability, i.e., under the medium/high speed of a ship or plane, stabilizer uses conventional operating mode, referred to as common stabilizer；
Under zero power test, stabilizer switches to zero power test pattern, is referred to as fin stabilizer at zero speed.Though the design takes into account common stabilizer, only
Need to design, safeguard a set of equipment, cost and volume are limited to its executing agency using crank connecting link also without large increase
Driving structure and the maximum that can reach turns the inadequate natural endowment that fin operating angle is only ± 40 °, the anti-rolling effect of zero power test has
Limit, it is impossible to meet ship and subtract the demand of shaking even under zero power test in the low speed of a ship or plane, complicated, weight and to account for cabin space big, to having
The cabin space arrangement of limit brings difficulty.
The content of the invention
In order to overcome existing fin stabilizer executing agency to turn, fin angle is not enough, and the present invention provides one kind and can realized turns fin angle greatly
Stabilizer executing agency, fin axle is directly driven by gear double rack cylinder and rotated, the quick large angle pendulum of fin is driven, realizes zero
The speed of a ship or plane, which subtracts, to be shaken, and the mechanism structure is simply compact, and can significantly reduce executing agency accounts for cabin space, and operating angle is up to ± 65 °, full
Corner demand during sufficient zero power test, it is ensured that good anti-rolling effect, while system reliability can be increased substantially.
To achieve the above object, the technical scheme is that：It is a kind of to realize the big stabilizer executing agency for turning fin angle,
Including fin axle group, fulcrum bearing, rack-and-pinion cylinder, retaining mechanism, fin angle transmitter, control valve group, the rack-and-pinion cylinder is installed
