[0001] This invention relates to the field of marine technology, and more particularly to an anti-roll system and a ship. Background Technology

[0002] Due to the development of the shipping industry, ships are gradually increasing in size and carrying capacity, and are increasingly trending towards larger, more automated, and more intelligent designs. In order to maintain the ship's lateral balance and ensure the smooth progress of loading and unloading processes, it is usually necessary to install anti-roll systems on the ship to avoid lateral tilting problems.

[0003] Existing anti-roll systems installed on ships are typically pump-controlled, valve-controlled, or pneumatic, adjusting buoyancy by injecting water or air into the buoys. These existing anti-roll systems suffer from problems such as long response times, lengthy anti-roll adjustment processes, and insufficient flexibility.

[0004] Therefore, there is an urgent need for an anti-roll system and a vessel to solve the above problems. Summary of the Invention

[0043] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0044] Figure 1 A side view showing the anti-roll system provided in an embodiment of the present invention arranged on a ship; Figure 2 A bottom view showing the anti-roll system provided in an embodiment of the present invention arranged on a ship; Figure 3 Show Figure 2 A magnified view of a section marked A in the middle; Figure 4 A schematic diagram of the detection unit and control unit provided in an embodiment of the present invention is shown. (Refer to...) Figures 1-4 This embodiment provides an anti-roll system and a vessel. The vessel includes a vessel body 10 and the anti-roll system provided in this embodiment. The anti-roll system is disposed at the bottom of the vessel body 10.

[0045] The anti-roll system includes a counterweight unit 100, a detection unit 200, and a control unit 300. The counterweight unit 100 includes a counterweight device 110, which is capable of moving laterally along the hull of the vessel 10. By moving the counterweight device 110 laterally along the hull of the vessel 10, the weight on both sides of the hull 10 can be balanced laterally, thereby improving the vessel's anti-roll capability. The detection unit 200 is disposed on the hull 10 and configured to detect the roll state of the hull 10. The control unit 300 is disposed on the hull 10, and the counterweight unit 100 and the detection unit 200 are communicatively connected to the control unit 300. The control unit 300 can control the movement of the counterweight device 110 laterally along the hull 10 based on the roll state detected by the detection unit 200. The control unit 300 can automatically control the movement of the counterweight device 110 based on the detection results of the detection unit 200, thereby regulating the lateral balance of the ship body 10. The counterweight device 110 can adjust the balance of the ship body 10 simply by moving; this action has a short response time and the adjustment process is quick, improving the flexibility of the anti-roll system.

[0046] Specifically, the counterweight unit 100 also includes a guide rail 120. The guide rail 120 is arranged laterally along the hull of the ship 10, and the counterweight device 110 is slidably mounted on the guide rail 120. By setting the guide rail 120, the movement of the counterweight device 110 can be guided, ensuring that the counterweight device 110 can move laterally along the hull of the ship 10, and ensuring the response speed and accuracy of the ship's anti-heel adjustment.

[0047] More specifically, the guide rail 120 is provided with a plurality of counterweight devices 110. In this embodiment, two counterweight devices 110 are provided on the same guide rail 120, and the two counterweight devices 110 are disposed on the guide rail 120 and are respectively distributed on both sides of the longitudinal axis of the ship body 10.

[0048] For example, when the ship body 10 exhibits a port roll in the lateral direction (i.e., the draft on the port side of the ship body 10 is greater than the draft on the port side in the lateral direction), the control unit 300 controls the counterweight device 110 to slide along the guide rail 120 to the right to increase the weight on the right side and decrease the weight on the left side, thereby adjusting the balance of the ship body 10 in the lateral direction.

[0049] More specifically, the counterweight unit 100 also includes a drive device connected to the counterweight device 110 and configured to drive the counterweight device 110 to move. The drive device is communicatively connected to the control unit 300, which can control the start and stop of the drive device, thereby controlling the movement of the counterweight device 110.

[0050] Optionally, in this embodiment, the driving device is a piezoelectric ceramic module 130. The counterweight device 110 has piezoelectric ceramic modules 130 respectively disposed on both sides of the ship's hull 10 in the transverse direction. The piezoelectric ceramic modules 130 are communicatively connected to the control unit 300 via a driving circuit. The control unit 300 can apply voltage to the piezoelectric ceramic modules 130 through the driving circuit, causing the piezoelectric ceramic modules 130 to deform under the influence of an electric field, thereby driving the counterweight device 110 to move. The aforementioned piezoelectric ceramic module 130 has high precision and a fast response speed.

[0051] Alternatively, in other embodiments, the drive device may be an electrically controlled hydraulic device or the like, as long as it can operate and drive the movement of the counterweight device 110.

[0052] Preferably, there are multiple sets of counterweight units 100, which are spaced apart along the longitudinal direction of the ship body 10. This arrangement allows for improved accuracy of anti-roll adjustment by moving multiple counterweight devices 110, and enables adjustment of roll at multiple positions along the longitudinal direction of the ship body 10, thus facilitating balanced adjustment of the entire ship body 10.

[0053] Continue to refer to Figure 1 , Figure 2 and Figure 4 The detection unit 200 includes a gyroscope 210, a motion sensor 220, and an electronic tiltmeter 230, all of which are communicatively connected to the control unit 300. The gyroscope 210 is configured to detect the angular velocity and bearing of the vessel hull 10. The motion sensor 220 is configured to acquire motion state information, velocity information, and acceleration information of the vessel hull 10. The electronic tiltmeter 230 is configured to measure the tilt angle of the vessel hull 10.

[0054] Specifically, the control unit 300 includes a signal collection device 310. The signal collection device 310 is communicatively connected to the detection unit 200 and configured to receive the tilt state detection signal from the detection unit 200. The signal collection device 310 is also communicatively connected to the drive device of the counterweight unit 100 and configured to control the movement of the counterweight unit 110.

[0055] More specifically, the control unit 300 also includes a display device 320, which can display the roll state detected by the detection unit 200. Through the display device 320, the angular velocity, bearing, motion state information, motion speed information, motion acceleration information, and roll angle of the ship body 10 can be displayed, making it convenient for operators to accurately know the state of the ship.

[0056] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
