Description

Technical Field

[0001] The present invention relates to the technical field of ship and marine engineering anti-rolling devices, and more particularly to a fluid momentum wheel active control anti-rolling device with self-adaptive precession direction. Background Art

[0002] When ships and offshore engineering platforms encounter large disturbances in the marine environment at sea or underwater, they will produce significant swaying motions, which will have an adverse effect on the ships and offshore engineering platforms. There are various means of reducing the rolling at sea, mainly including fins, water tanks and other single-direction methods.

[0003] The use of fluid momentum wheel for anti-rolling has become a new anti-rolling method, which can increase the anti-rolling effect by using active precession. For example, CN113335470B discloses a wave-direction adaptive fluid momentum wheel active control anti-rolling device, which discloses that a rotary motor drives the entire momentum wheel to rotate 360°, and then the first hydraulic cylinder and the second hydraulic cylinder cooperate to drive the momentum wheel to swing, so that the momentum wheel generates anti-rolling torques in different directions. However, the anti-rolling torques in different directions achieved by the above momentum wheel are achieved by first adjusting the position of the momentum wheel according to the wave direction by the rotary motor, and then the momentum wheel is swung by the hydraulic cylinder, that is, the momentum wheel cannot directly generate anti-rolling torques to resist waves of any direction on the horizontal plane, thereby reducing the efficiency and effect of the momentum wheel anti-rolling.

[0004] Therefore, how to provide a precession direction adaptive fluid momentum wheel active control roll stabilization device that can directly generate a roll stabilization torque against any direction on the horizontal plane in the active precession direction of the fluid momentum wheel to improve the roll stabilization efficiency and effect is a problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0005] In view of this, the present invention provides a fluid momentum wheel active control anti-rolling device with adaptive precession direction, which can enable the active precession direction of the fluid momentum wheel (the active precession direction is the direction perpendicular to the wave direction) to be directly and arbitrarily changed, thereby quickly resisting the interference of the marine environment from different directions to improve the anti-rolling efficiency and effect.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] A fluid momentum wheel active control anti-roll device with self-adaptive precession direction, comprising:

[0008] A bottom bracket, a support column is fixed to the middle of the top of the bottom bracket, and a main joint bearing is installed on the end of the support column away from the bottom bracket;

[0009] A top bracket, wherein the middle portion of the top bracket is connected to the main joint bearing;

[0010] A fluid momentum wheel, wherein four connecting sleeves are evenly arranged on the fluid momentum wheel, a spherical bearing is fixed on the outer wall of each connecting sleeve, and each connecting sleeve is fixedly connected to the outer edge of the top bracket;

[0011] Active precession telescopic components, the number of which is four, and the bottom ends of which are hingedly connected to the outer edge of the top end of the bottom bracket, and the top end of each active precession telescopic component is connected to the corresponding joint bearing;

[0012] Controllers, the number of the controllers being four and being fixed to the top of the bottom bracket respectively and being electrically connected to the corresponding active precession telescopic components respectively;

[0013] Wherein, the two opposite active precession telescopic components form a group, and the two groups of active precession telescopic components are arranged orthogonally.

[0014] It can be known from the above technical scheme that, compared with the prior art, the present invention discloses a fluid momentum wheel active control anti-rolling device with adaptive precession direction, which drives the fluid momentum wheel to swing through two groups of orthogonally arranged active precession telescopic components, so that the fluid momentum wheel generates a gyroscopic moment in a specified direction. That is, when one group of active precession telescopic components is working, the fluid momentum wheel can generate a rotation of one degree of freedom in the horizontal plane, thereby generating a gyroscopic moment in the corresponding direction; when the two groups of active precession telescopic components are independently controlled, the fluid momentum wheel can generate a rotation of two degrees of freedom in the horizontal plane, and when two adjacent active precession telescopic components are working, the fluid momentum wheel can generate a rotation of one degree of freedom in the horizontal plane. Therefore, the anti-rolling device of the present invention can directly generate a rotation around any axis in the horizontal plane through the organic combination of corresponding active precession telescopic components, so that the fluid momentum wheel generates a gyroscopic moment around any axis in the horizontal plane, that is, it can generate a gyroscopic moment that is adapted to the interference direction of the external environment of the ship and the marine engineering operation platform, thereby better improving the conditions for the platform to complete the operation task. In addition, the active precession direction of the fluid momentum wheel of the present invention can be directly and arbitrarily changed, thereby quickly resisting the interference of the marine environment from different directions, thereby improving the anti-rolling efficiency and effect.

[0015] Furthermore, the bottom bracket comprises:

[0016] A central bottom plate, the support column being fixed to the top of the central bottom plate;

[0017] The mounting base plate has four mounting base plates, and one end of each mounting base plate is evenly distributed and fixedly connected to the outer wall of the central base plate, and the other end of the mounting base plate extends radially outward, the bottom end of the active precession telescopic component is hingedly connected to the top end of the mounting base plate near the other end thereof, and the controller is fixed on the top end of the mounting base plate.

[0018] The beneficial effect of adopting the above technical solution is that the bottom bracket has a cross-shaped structure, which is simple in structure and easy to process and manufacture.

[0019] Furthermore, the top bracket includes:

[0020] A connecting tube, wherein the connecting tube is sleeved on the main joint bearing;

[0021] There are four connecting rods, one end of which is evenly distributed and fixedly connected to the outer wall of the connecting tube, and the other end of the connecting rod is fixedly connected to the corresponding connecting sleeve.

[0022] The beneficial effect of adopting the above technical solution is that the top bracket has a cross-shaped structure, which is simple in structure and easy to process and manufacture.

[0023] Furthermore, a flange plate is fixed to the other end of the connecting rod, a connecting boss is integrally formed on the outer wall of the connecting sleeve facing the flange plate, and the flange plate is fixedly connected to the connecting boss by bolts.

[0024] The beneficial effect of adopting the above technical solution is that the top bracket and the connecting sleeve can be quickly disassembled and assembled easily, and the operation is simple.

[0025] Furthermore, the active precession telescopic component is an electric push rod, a hydraulic push rod, or a pneumatic push rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] A flange plate 43 is fixed to the other end of the connecting rod 42 , and a connecting boss 61 is integrally formed on the outer wall of the connecting sleeve 6 facing the flange plate 43 . The flange plate 43 and the connecting boss 61 are fixedly connected by bolts.

[0045] The active precession telescopic component 8 is an electric push rod, a hydraulic push rod or a pneumatic push rod, and the hydraulic push rod is preferred in the present invention.
