Abstract
The utility model discloses a marine universal shimmy damping device. The marine works or sails on the sea with periodic wave motion, and the shimmy of the marine often brings a series of troubles. The marine universal shimmy damping device uses the character of the universal rolling of the sphere and the gravitational effect of the pendulum and converses the restoring torque the marine tilted and subjected into the relative rolling of the sphere and the ball, which damps the amplitude value of the shimmy markedly. The utility model has the advantages of simple structure, convenient operation, low cost, and good shimmy damping effect. The common hardware factory can totally manufacture the marine universal shimmy damping device.
Description
The utility model is the universal antirolling apparatus that a kind of suitable boats and ships use.
Ship operation on the sea with periodically wave motion, navigation, regular meeting bring a series of trouble, have influenced crewman's normal operation and passenger's daily life diet because of waving to crewman and passenger of boats and ships.
Existing inflatable antirolling apparatus peculiar to vessel (US Patent 4140074) utilize air cushion buffering principle, reduced the righting moment that ship is subjected to after inclination, make the rolling period of boats and ships substantially exceed the cycle of wave motion, thereby significantly reduced the amplitude of waving.This inflatable antirolling apparatus peculiar to vessel be box, must communicate with seawater, subtract simultaneously that to shake direction be unidirectional, to arrange symmetrically according to the geometric centre of ship during practical application, as on four angles that are installed in vertex of a triangle or rectangle, could not only reduce rolling but also reduce pitching, though this device is more superior than traditional antirolling tank, but structure is comparatively complicated, and floor area is big, cost is also high.
Task of the present utility model is to make a kind of simple in structure, cheap and better universal antirolling apparatus peculiar to vessel of stabilizing efficiency.
The purpose of this utility model is to realize like this; Universal antirolling apparatus comprises pallet, ball, fork, pendulum, pearl dish, support and spring, when ship is tilting, the also run-off the straight of support of this device, righting moment that riding is subjected to act on ball by the ball of pearl dish, thereby because the friction between ball and the ball is little, reduced the amplitude of waving on original center of gravity vertical line significantly still remaining under the action of gravity of pendulum, when making ball be subjected to the application force of support.
The utility model has the effect that reduces friction, ship is converted into relative rolling between ball and ball at the righting moment that is subjected to after the inclination because be conceived to characteristics that ball has a universal rotation and spin, utilize the action of gravity of pendulum that ball is remained on original center of gravity vertical line under the situation that any direction waves being subjected to simultaneously, so stabilizing efficiency is good, simple in structure, it is also very convenient to use.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Describe details and service condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes.
This device comprises ball (1), pallet (2), fork (3), pendulum (4), pearl dish (5), support (6), spring (7).
When heel, support (6) tilts too, support (6) tilts to be subjected to righting moment by pearl dish (5) pass to ball (1), because ball (1) is very little with friction between the pearl dish (5), at pendulum (4) though action of gravity under pearl coil (5) to any direction tilt, ball (1) remains on original center of gravity vertical line, thereby significantly reduced the amplitude of waving, reached the universal purpose of shaking that subtracts simultaneously, spring (7) plays buffer action between pendulum (4) and support (6).
Shown in Figure 2 is according to principle design of the present utility model to specialize in stove peculiar to vessel, this stove peculiar to vessel that crewman's cooking uses be exactly that common stove and accessory is fixed on the pallet (2) of universal antirolling apparatus.
Shown in Figure 3 is according to principle design of the present utility model specialize in that the passenger takes on the ship subtract rocking chair (bed), this rocking chair (bed) that subtracts is exactly that common seat (bed) is fixed on the pallet (2) of universal antirolling apparatus.
Claims (4)
1, being fit to peculiar to vessel universal antirolling apparatus, this device that boats and ships use has a ball (1), ball (1) upper end to have in succession fork (3) and pendulum (4), pearl of individual pallet (2), lower end to coil the weight that (5) and support (6) support ball (1), pallet (2), fork (3), pendulum (4), connect with spring (7) between pendulum (4) and the support (6), it is characterized in that pearl dish (5) contacts with ball (1) by ball.
2, device according to claim 1, it is characterized in that ball (1) is under the action of gravity of pendulum (4), still can remain on original center of gravity vertical line when pearl dish (5) tilts.
3, device according to claim 1 and 2, it is characterized in that pearl dish (5) can be on ball (1) be 60 °-90 ° universal rotation as central angle.
4, device according to claim 1, it is characterized in that between pendulum (4) and support (6) connecting and playing buffer action with spring (7).
