Description
Technical field
The present invention relates to a kind of shipborne equipment for reducing rolling, it can change and change the bilge keelson of shape according to sea situation,
The flexible bilge keelson system driven for a kind of gear of ship stabilization anti-dumping.
Background technology
Influence of the rolling of ship to ship performance is maximum, in order to slow down or reduce the yaw of ship, can add on ship
If stabilizer.At present, the conventional stabilizer of ship has：Bilge keelson, stabilizer, tank stabilizer, free gyroscope stabilizer, rudder
Stabilizer etc..Wherein, bilge keelson is because its is simple in construction, low cost, easy to maintenance, efficiency are preferably used widely, several
Every ship is equipped with bilge keelson.It is to be produced using it on hull turn of the bilge shell to ship that bilge keelson, which subtracts the principle shaken,
The additional water resistance of rolling, to reduce ship rolling.
In general, bilge keelson is fixedly mounted at the hull outside turn of the bilge and as far as possible vertical with bilge strake, along current side
To a block length batten, it is a kind of simplest passive type hydrodynamic force ship stabilizer.
Existing technological improvement is often directed to simple linear end and improved and section optimization, as use is long and narrow
Bilge keelson, segmentation structure, triangular cross-section structure etc..
There is following defect and deficiency in existing bilge keelson structure type：It is subject to damage；Certain navigation is produced to ship
Resistance.Moreover, limited by bilge keelson size, subtract that the damping torque shaken is limited, subtract the ability (the reduction amplitude of oscillation) shaken and be limited, subtract and shake
Effect is general 10%~20% or so, it is difficult to meet demand.In addition, for the bilge keelson of determination, due to bilge keelson shape chi
Very little fixation, it is impossible to which the emergency of change and roll angle and acceleration for sea situation enters Mobile state adjustment, greatly influences it
Use scope.
The content of the invention
It is an object of the invention to overcome the shortcomings of prior art presence, there is provided a kind of flexible bilge keelson system of gear driving
System.The control system integration ship motion real-time watch device of bilge keelson of the present invention, according to the violent journey of the ship rolling detected
The data of degree, are controlled automatically or manually the flexible of bilge keelson by driver.The bilge keelson effective area maximum increase of extended configuration
By about one time, the roll damping of ship can be increased, effectively reduce the rolling of ship, enhanced static pitching stability；Folded state
Bilge keelson monnolithic case fairing, ship resistance will not be increased, ship resistance and performance is not interfered with.By installing this sleeve gear additional
The flexible bilge keelson system of driving, can make ship flexibly and efficiently realize the purpose of control rolling, tackle various complicated sea situations
With the change of loading conditions.
The flexible bilge keelson system of a kind of gear driving of the present invention, by bilge keelson agent structure, and in bilge keelson main body
The add-in card that can be stretched, withdraw along the slide rail composition of top.Described bilge keelson agent structure, the side close to hull side

Upper add-in card, promotes add-in card to stretch, withdraw.Rack 4 is located in bilge keelson agent structure slideway groove, can also protect this
Body structure, prevents from being damaged.
As shown in fig. 6, the flexible bilge keelson system of the gear driving of the present invention, its control system is by the real-time prison of ship motion
System, motor control system composition is presented in measurement equipment, data analysis.The fluid level measuring instrument set in shipboard, to prison in real time
Survey the drinking water of the side of a ship of ship two.Dynamic parameter measurement instrument is set near ship mass axis position, in real time the rolling of monitoring ship
The data such as speed, angular speed.Data analysis is presented system and the electric signal monitored is inputted into computer, is converted into corresponding physics
Amount, draws the motion state of ship accordingly, and provides the good and bad judgement of ship navigation state, and bilge keelson add-in card stretches
Suggestion, it is intuitively presented on the corresponding screen of driver's cabin., can be by calculating as a kind of way of realization of this patent
Machine is manipulated automatically, and auxiliary controls motor rotation with human pilot manual manipulation motor control system, finally makes clamshell bilge dragon
Bone is correspondingly realized expansion or folded, and automatically adjusts ship rolling.Can certainly be completely by human pilot manual manipulation motor
Control system.
In ship's navigation, ship motion real-time monitoring system detects ship rolling angular speed, angular acceleration etc., with reference to
Drauht, inputs computer as parameter, checks ship transverse stability, if persistently beyond a certain in the regular hour is interval
Secure setting, judge that then data analysis is presented system and can send alarm to driver's cabin ship, and result is included in screen
On.The add-in card 2 of subsequent motor control system Automatic-expanding bilge keelson, as shown in figure 3, increase bilge keelson effective area, has
The increase roll damping of effect ground, suppresses rolling.If being consistently less than a certain specific value, ship rolling in the regular hour is interval
The add-in card 2 of very little, then motor control system automatic drawing back bilge keelson, as shown in Figure 2.
For navigating by water in the case of limit irrigation or other particular/special requirements, it is necessary to fold (or expansion) bilge keelson, Ke Yiyou
Driver controls bilge keelson folding manually.
It is above-described, it is only, to explain presently preferred embodiments of the present invention, to be not intended to make any to the present invention according to this
Formal limitation, it is then, all to have any modification or change made under identical creation spirit, it should be included in this hair
Bright scope of the claims.
