TECHNICAL FIELD

[0001] The application belongs to the field of ship magnetic sensing technology application, and particularly relates to an ion conductor electromagnetic induction system for a ship. BACKGROUND

[0002] During the operation of marine equipment such as ships and offshore platforms, structural vibrations such as rolling and pitching caused by wave excitation not only affect the stability of the equipment, but also may cause structural fatigue, personnel discomfort, and even navigation safety hazards; in order to control vibration and improve the stability of the ship body posture, mechanical dampers, hydraulic damping devices or additional buoy structures are commonly used in traditional engineering to dissipate energy and buffer; however, these methods generally have problems such as response lag, limited adjustment capacity, complex structure, and difficult maintenance, especially in the marine environment which is wet, highly corrosive and strongly disturbed, so the failure rate is high and the service life is limited, which cannot meet the needs of new marine equipment with high performance and low maintenance;

[0003] In the prior art, electromagnetic induction damping systems are widely concerned due to their fast response, strong adjustability and small mechanical wear; however, common electromagnetic dampers rely on the movement of metal conductors such as aluminum plates and copper discs in a magnetic field to form induced current, and then generate a reverse Lorentz force to achieve vibration reduction; such structures require the introduction of specific moving components, resulting in complex structure and limited installation, and are not suitable for direct operation in seawater environment; on the other hand, seawater as a natural ion conductor is abundant and has good conductivity, but its utilization rate in existing damping technology is very low;

[0052] The working principle or process of the present application is as follows:

[0053] When the ship is sailing in water, the magnetic field generating module arranged in the damping cabin inside or at the bottom of the ship body forms a magnetic field with a clear direction and stable magnetic flux density; At this time, the seawater in the magnetic field as an ion conductor produces relative displacement in the magnetic field with the movement of the ship body, thereby causing the charged ions in the ion conductor to cut the magnetic induction lines;

[0054] According to the principle of electromagnetic induction, during the relative motion of the ion conductor in the magnetic field, the area where the motion direction is perpendicular to the magnetic field direction will form a gradient induced electromotive force; The electromotive force acts on the electrode assembly along the conductive path to drive it to generate induced current;

[0055] The induced current generates electromagnetic force in the magnetic field, which acts in the opposite direction to the motion direction of the ion conductor; This force not only provides damping effect for the ship to suppress unwanted oscillation or roll, but also forms thrust consistent with the heading under the control of a specific magnetic field direction, which plays the role of auxiliary propulsion;

[0056] The control unit adjusts the magnetic induction strength and direction of the magnetic field generating module in real time by obtaining the ship motion state parameters such as acceleration, speed and attitude, realizes the precise control of the induced electromotive force, and thus achieves the purpose of adjusting the damping force or thrust;

[0057] The whole system constitutes a closed-loop dynamic process of "motion → induction → feedback force → control", which can adaptively respond according to the sailing conditions to enhance the sailing stability and maneuvering performance of the ship.

[0058] Specifically, in one embodiment of the present application, the magnetic field generating module includes a symmetrically distributed neodymium iron boron permanent magnet array or an embedded adjustable electromagnetic coil array, which is arranged in the damping cabin on the inner side or bottom of the ship body structure; the electrode assembly is made of titanium alloy and plated with platinum-iridium alloy on the surface; a flow guide channel is arranged between the electrode assembly and the seawater, the inner wall of the flow guide channel is coated with a hydrophobic coating for inhibiting marine organism attachment and maintaining the free flow of the induced path; the control unit includes an acceleration sensor, a speed sensor and a processor, which automatically adjusts the working parameters of the magnetic field generating module based on the ship body vibration state data obtained by the sensor; the control unit cooperates with the magnetic field generating module and the electrode assembly to reverse the direction of the electromagnetic force generated by the interaction of the induced current and the magnetic field by changing the direction of the magnetic field, so as to realize ship braking damping or propulsion output according to different working states; part of the conductive loop path is electrically connected through the ship body metal structure, and the two ends of the path are electrically isolated from the magnetic field area through insulating materials; the ship is matched with a modular structure unit, each unit includes a group of magnetic field generating modules, a pair of electrode assemblies and a local control sub-module, which are arranged in the ship body structure for vibration control or propulsion auxiliary control in more than one direction of the ship body; the control unit switches the magnetic field direction and strength according to different working modes to achieve different control targets; the electromagnetic coil of the magnetic field generating module is a segmented activation structure for partition excitation of the target magnetic field; the control unit includes a ship speed prediction module, which predicts the damping demand according to the ship attitude change and activates the corresponding magnetic area; a soft magnetic closed loop is arranged between the magnet arrays for guiding the closure of the magnetic force line; a current rectification device is used to recover part of the electric energy in the induced current to the power supply system energy storage module; the electrode assembly is matched with a self-detection module for judging the electrode contact state, current integrity and seawater conductivity change and outputting fault warning information; the magnets in the magnetic field generating module are arranged in a bipolar staggered manner, and the alternating arrangement direction of the poles is perpendicular to the ship body running direction, which is used to improve the strength of the gradient induced electromotive force;

[0059] The application has the technical features that: in order to realize efficient electromagnetic induction damping and thrust control, the modular structure unit adopts a transom embedded arrangement mode, is integrated with the ship body structure, and the original strength distribution is avoided from being damaged; the permanent magnet array and the electrode assembly are installed in the composite material shell, the shell and the ship body are fixed through insulating fasteners, and electromagnetic isolation is ensured; the electrode assembly is installed behind the maintenance window in a pluggable design, and regular maintenance and replacement are facilitated; the flow guide channel adopts a three-dimensional curved surface flow guide structure, the local flow rate is enhanced, and salt accumulation is prevented; the processor in the control unit communicates with the ship navigation system, can quickly identify the attitude change trend under wind and wave disturbance, and activates the relevant magnetic area in advance to form a time sequence multi-point control; the electromagnetic coil driving module supports PWM fine modulation, realizes closed-loop control of the magnetic flux change rate, and the energy recovery part adopts a bidirectional DC-DC module and a super capacitor in cooperation, adapts to the instantaneous fluctuation characteristics of the induced current, and effectively prolongs the service life of the energy storage system; the whole system can dynamically switch between multiple modes such as roll reduction, attitude stabilization, steering assistance, etc. through a software-defined control strategy, and the control stability and energy utilization efficiency of the ship under complex navigation conditions are significantly improved.

[0060] Specifically, in one embodiment of the application, the application provides an ion conductor electromagnetic induction system for a ship. By controlling the relative motion relationship between the magnetic field and the ions in seawater, the system can form a directional induced current around the ship body without relying on traditional mechanical structures, and generate controllable damping force or propulsion force through electromagnetic action, thereby being used for ship attitude stabilization or navigation power control.

[0061] When the ion conductor is placed in a uniform and stable magnetic field (generated by the N and S poles of the magnet) and moves relative to the magnetic field (with a relative speed of V), the charged ions cut the magnetic induction lines to produce a directional motion component, resulting in the accumulation of electric charges to form a gradient electromotive force U. The electromotive force drives the conductive material to generate an induced current I. According to Lenz's law, the magnetic field effect of the induced current will generate a damping force opposite to the direction of relative motion, forcing the ion conductor to reduce the speed V, and finally realizing system stability.

[0062] The ion conductor electromagnetic induction system comprises:

[0063] A magnetic field generating module: arranged inside or outside the ship body, for forming a stable or adjustable magnetic induction field in a specified area;

[0064] An ion conductor module: using seawater as an ion conductor medium, placed in the magnetic field action area;

[0065] An electrode assembly: distributed between seawater and the ship body, forming an induced current path;

[0066] A control unit: for adjusting the magnetic field strength, distribution or switching the magnetic field direction, controlling the direction and strength of the induced current;

[0067] When the ship hull vibrates or displaces relative to the surrounding seawater, the ions in the seawater will move along the magnetic field lines under the action of the magnetic field, forming a gradient electromotive force; this electromotive force drives the conductive path in the electrode system to form an induced current; according to Lenz's law, the induced current generated will further cause an opposite electromagnetic force in the system, thereby generating resistance or thrust on the ship hull;

[0068] By adjusting the direction and strength of the magnetic field:

[0069] When the magnetic field direction and the induced current direction act as a braking state, a damping effect is generated, which is suitable for vibration control;

[0070] When the magnetic field is adjusted tangentially to be consistent with the target motion direction, a thrust effect is generated, which is used for small-range boosting or attitude adjustment;

[0071] The ion conductor induction system is characterized by using the ion conductor in the magnetic field to produce relative motion with the magnetic induction lines to obtain a gradient induced electromotive force; the conductive material under the action of the induced electromotive force will generate an induced current, and the effect of the induced current will hinder the movement trend of the ion conductor in the magnetic field;

[0072] The magnetic field generation module can generate moving ion conductors and an induced magnetic field in the direction of ion movement; the ion conductor can produce relative motion with the magnetic induction lines of the magnetic field to obtain a gradient induced electromotive force;

[0073] The gradient induced electromotive force generated by the ion conductor electromagnetic induction system can act on the conductive material to generate an induced current; the effect of the induced current will hinder the movement trend of the ion conductor in the magnetic field; the ion conductor is placed in the magnetic field, and the magnetic field between the N and S poles of the magnet is uniform and stable, such as Figure 1 ;

[0074] When the ion conductor moves relative to the magnetic field, the charged ions in the magnetic field will have a directional motion component that cuts the magnetic field lines (relative speed V); the charged ions in the conductor will gather under the action of the magnetic field, thereby forming a gradient electromotive force U in the magnetic field; under the action of this electromotive force, an induced current I will be generated in the conductor in this environment, such as Figure 2 ; At this time, the ion conductor electromagnetic induction system will generate a damping that reduces the movement speed V of the ion conductor relative to the magnetic field, so that the entire system tends to be stable;

[0075] A permanent magnet array can be used to build a uniform and stable N-S pole magnetic field, such as a neodymium iron boron magnet material; the magnets are symmetrically distributed in the damping cabin on the bottom or side plate of the ship hull, and adjacent magnets are connected by a soft magnetic yoke to enhance the uniformity of the magnetic field. The magnet module adopts a detachable clamping slot structure, is wrapped with a glass steel insulation shell, realizes modular replacement, and can be replaced independently when a single magnet module fails without affecting system operation;

[0076] In the ship's bilge keel or stern design embedded damping cavity, magnet array is integrated with guide plate, the outside of the cavity is covered with water permeable mesh plate to prevent marine organisms from blocking, the aperture of the mesh plate is less than or equal to 5mm; the inside is fixed with ion conductor assembly (such as gel electrolyte plate) through insulating support. Modular design supports conformal with ship structure, adapts to the damping needs of different ship types (such as cargo ship, yacht, submarine). The two ends of the ion conductor are connected with the inner and outer seawater through titanium alloy electrodes, and the surface of the electrode is plated with platinum-iridium alloy to enhance the conductivity. The inner electrode is directly attached to the ion conductor (such as solid electrolyte ceramic sheet), and the outer electrode extends to the outside seawater area of the ship body, forming a closed conduction loop of "magnet magnetic field→ion conductor→inner electrode→ship body metal structure→outer electrode→seawater". A polytetrafluoroethylene insulating layer is arranged between the ion conductor and the ship structure to avoid the generation of stray current caused by the direct cutting of the ship metal on the magnetic induction line; a flow guide channel is arranged in the seawater conduction path, the inner wall of the channel is coated with a hydrophobic coating to reduce marine organism attachment and ensure the long-term stability of the conduction path;

[0077] Through the modular permanent magnet array, closed-loop control strategy and multiple corrosion prevention design, the ion conductor electromagnetic induction system is realized in the engineering application in the marine environment; the innovation lies in the combination of the gradient electromotive force characteristics of the ion conductor and the vibration energy reduction of the ship body, and at the same time, the bottleneck of the traditional damping system in response speed, adjustment accuracy and environmental adaptability is solved, which provides a new technical scheme for the fields of ship shock absorption, offshore platform stability and the like.

[0078] In general, the present application aims to solve the lack of damping method and device for adjusting the navigation of the existing ship during navigation in addition to the driving, and provides an electromagnetic induction system based on seawater as an ion conductor, which realizes non-contact induction damping or thrust output through the action of a magnetic field; by integrating a modular magnetic field generating device, an electrode assembly and a control unit in the ship body structure, combining the relative motion of ions generated by the natural flow of seawater or the vibration of the ship body, a closed loop of induced electromotive force is constructed, high response, adjustable, low maintenance, environmentally friendly dynamic control damping or thrust is realized, and an innovative solution is provided for the steady-state control and intelligent propulsion of the ship.

[0079] The above only describes the preferred embodiments of the present application, and it should be noted that for ordinary skilled persons in the technical field, several improvements and replacements can be made without departing from the technical principles of the present application, and these improvements and replacements should also be considered as the protection scope of the present application.
