Description
Technical field
The present invention relates to a kind of novel subtract of rotary type to shake equipment.
Background technique
The sea-keeping of ship refers to the ability that ship navigates by water under stormy waves sea situation.Ship seakeeping has weight to ship's navigation
The influence wanted, on the one hand the goods movement due to caused by rolling is likely to result in ship and topples, on the other hand due to pitching and liter
The effect of heavy movement, ship is likely to occur a series of phenomenons such as slamming, upper wave, splashing, propeller stall, to influence ship
Navigation performance.
Roll damping is very big on the rolling of ship influence, and traditional stabilizer cannot effective work in the low speed of a ship or plane of zero power test
Make, though the appearance of fin stabilizer at zero speed solves this problem, power required for it is larger, and involves great expense,
It is suitable for the high values ships such as military ships at present more.Tank stabilizer occupancy volume of compartment is excessively high, and traditional bilge keelson is not take up volume of compartment and makes
Valence is cheap, but is limited to ship type, and width must not exceed in half the wide line and baseline range of ship, and which limits bilge keelsons in the speed of a ship or plane
Anti-rolling effect when higher.
The shortcomings that prior art are as follows:
(1) high and easy to wear using novel stabilizer cost.The prior art such as Patent No. CN108860500A is " a kind of
Novel ship stabilizer "
(2) using air bag subtract shake occupy volume of compartment it is higher.The prior art such as Patent No. CN109229296A is " a kind of controllable
Formula air bag stabilizer and its stabilization method "
Summary of the invention
In view of the above-mentioned problems, the purpose of the present invention is novel subtract for providing a kind of rotary type in the hull turn of the bilge to shake equipment.
Equipment proposed by the present invention can guarantee the anti-rolling effect under the various speed of a ship or plane, while can take into account various sea situations, both ensure that
Anti-rolling effect under severe sea condition, and lower resistance is able to maintain in more tranquil sea situation, realize economy and safety
The unification of property.To achieve the above object, the present invention takes following technical scheme:
A kind of rotary type, which subtracts, shakes equipment, including three groups of structures are identical, the distinguishing stabilizer of size, and every group subtracts and shake dress
It sets including outer shaft, inner shaft and subtracts rocker, which is characterized in that outer shaft is connected with inner shaft by support rod, at the both ends of outer shaft point
It is not provided with external gear, internal gear wheel is respectively arranged at the both ends of inner shaft, between ipsilateral external gear and internal gear wheel
By driving chain, by driving the rotation of internal gear wheel, and then drives external gear and subtract rocker rotation；Three groups of stabilizers
Be mounted within 1/3 to 1/4 captain of midship, it is wider that the stabilizer of middle groups subtracts rocker, in addition two groups it is then relatively narrow.
Preferably, described to subtract rocker according to hull turn of the bilge configuration design radian, guarantee that it is bonded hull bilge when packing up
Portion.The distance between every group of outer shaft is 1.5~2m.
The present invention provides it is a kind of effectively and the equipment that economically reduces hull rolling, have compared to existing technology with
Lower advantage:
(1) subtract rocker present invention employs fitting bilge portion radian, ship boat can be reduced to the greatest extent under orderly sea
Resistance brought by attached body in row improves navigation economy.
(2) present invention breaches the shape limitation for subtracting rocker when ship is stopped, and improves the effect for subtracting and shaking.
(3) the present invention provides a set of control systems, subtract the rotation of rocker by controlling system control, pass through active control
Method, improve the efficiency and the scope of application for subtracting and shaking.
(4) control device of the present invention is separated with rocker is subtracted, it is only necessary to anti-water controller be arranged in support rod end, guarantee
The leakproofness and economy of whole system.
(5) more driving chains are in board arranged in the present invention, even if there is minority to be damaged, are driven the energy that remains unchanged by other
Enough make to subtract to shake effective operation of apparatus, improves and subtract the reliability for shaking equipment.
(6) present invention is safe and reliable, can cope with a variety of sea situations

Specific embodiment
Of the invention is described in detail with reference to the accompanying drawings and examples.
As shown in Figure 1, equipment, including three groups of stabilizers are shaken in of the invention subtracting, one group of stabilizer includes outer shaft 2, axis
Upper connection subtracts rocker 1 and support rod 5.The other end of support rod 5 connects inner shaft 6.External gear 3 is installed at 2 both ends of outer shaft, in inner shaft 6
Internal gear wheel 9 is installed, is connected between external gear 3 and internal gear wheel 9 with driving chain 4.Control system 8 is controlled according to instruction
Power 7 works, and internal gear wheel 9 can be driven to rotate, and then drives external gear 3 and subtract the rotation of rocker 1.
As shown in Figure 1, subtracting rocker 1 according to hull turn of the bilge configuration design radian, guarantee the fitting hull turn of the bilge.Arc subtracts rocker 1
Width according to ship form design, and be no more than 600mm.2 support rods 5 are connected on each outer shaft 2, between every support rod 5
Distance be 3~4m.
This, which subtracts, shakes equipment and concentrates within 1/3 to 1/4 captain of midship installing 3 groups of stabilizers, between every group of outer shaft 3
Distance be 1.5~2m, stabilizer longitudinal end terminates near hull rigidity component, and the stabilizer of middle groups subtracts rocker
1 is wider, in addition two groups it is then relatively narrow, with reduce stress caused by structural mutation concentration.The equipment is mounted on the hull turn of the bilge, can account for
The volume of compartment of some bottom side tanks only has small effect to the volume of compartment of main cargo hold.
Illustrate that the novel telescopic subtracts to shake equipment and subtract under various sea situations with reference to the accompanying drawing and shake implementation process:
As shown in figure 3, extension type subtracts and shakes equipment to subtract the workflow shaken as follows: crewman inputs sea situation to control system 6
Information is inferred to subtract the most economical rotation angle of rocker 1 under this sea situation by motion value simulation or water trough model test.
As shown in Fig. 2, under orderly sea, stopping or subtracting rocker 1 when lying up and be close to ship side, navigation resistance can be reduced to greatest extent
Power.Increase in demand is shaken as sea situation badly subtracts, control system 8 issues command signal to power device 7, controls internal gear wheel 9
Rotation, and then drive external gear 3 and subtract rocker 1 and rotate by a certain angle, similar bilge keelson increases Ship Rolling Damping coefficient, into
And increasing rolling period, Nikolayev formula can be used in the calculating of equivalent linear damping, and stabilization at zero speed plate 1 is bonded completely
When, calculate the formula of zero dimension attenuation coefficient are as follows:
In formula: L, B, H, D are captain, type is wide, moldeed depth, displacement；kiIt is empirical coefficient, k is generally taken for seagoing vesseli=
0.055~0.060；ΦAFor rolling amplitude, 0.5~0.6rad is averagely taken.
Although preferred embodiment of the invention is described above in conjunction with attached drawing, the invention is not limited to above-mentioned
Specific embodiment, the above mentioned embodiment is only schematical, is not restrictive, the common skill of this field
Art personnel under the inspiration of the present invention, without breaking away from the scope protected by the purposes and claims of the present invention, can be with
Many forms are made, within these are all belonged to the scope of protection of the present invention.
