Description

Technical Field

[0001] The invention belongs to the technical field of power generation, and relates to a power generation system and a power generation method for a marine vessel. Background Art

[0002] Working vessels perform various tasks in the vast seas, such as marine scientific research, resource exploration, fishing, offshore construction, etc. Their continuous and stable power supply is the key to ensure the smooth progress of the mission and the safety of the crew. However, the marine environment is complex and changeable, especially when encountering extreme weather conditions (such as typhoons, huge waves, sea fog, etc.) and special sea conditions (such as reef areas, shoals, strong currents, etc.), ships face unprecedented challenges.

[0003] Under these unfavorable conditions, it is often difficult for ships to go to the preset offshore supply stations for power replenishment as planned, which not only affects the operating efficiency of the ship, but also poses a serious threat to the safety of the ship. For example, insufficient power supply first affects the ship's navigation system, including key equipment such as GPS, radar and autopilot. The failure of these systems may cause the ship to lose its sense of direction and increase the risk of collision, especially at night or in bad weather conditions. Secondly, insufficient power may also affect the ship's communication system, including satellite phones, VHF radios and walkie-talkies. Poor communication will make it difficult for the ship to keep in touch with the outside world, increasing the risk of being isolated and helpless. In addition, insufficient power will force various operating equipment on the ship to shut down, such as fishing equipment, scientific research instruments, construction machinery, etc. This will not only delay the progress of the mission, but may also cause economic losses. At the same time, in the case of insufficient power, the ship's night navigation will become particularly dangerous. Lack of sufficient lighting and navigation equipment support makes it difficult for the crew to accurately judge the surrounding environment, increasing the risk of collision and grounding, and insufficient power supply will weaken the ship's emergency response capabilities. In the event of fire, flooding or other emergencies, the lack of sufficient power support will seriously limit the crew's rescue operations and self-rescue capabilities.

[0004] Therefore, the phenomenon of insufficient power supply on offshore vessels is a complex issue involving multiple aspects. It not only affects the normal operation and efficiency of the vessel, but also threatens the safety and well-being of the crew and the protection of the marine environment. Summary of the invention

[0005] The purpose of the present invention is to solve the problem in the prior art that due to the complex and changeable marine environment and special sea conditions, it is often difficult for ships to go to the preset offshore supply station for power replenishment as planned, which not only affects the operating efficiency of the ship, but also poses a serious threat to the safety of the ship, affecting the ship's navigation stability, navigation accuracy and emergency response capabilities in emergency situations. A power generation system and power generation method for offshore ships are provided.

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

[0007] A power generation system for a marine vessel, comprising a hull, a plurality of adjacent tracks arranged on the hull, permanent magnets slidably connected to the tracks, and wires arranged between the plurality of adjacent tracks, the wires connecting power generation units;

[0008] When the permanent magnets slide along the track, electrical energy is generated, which is transferred to the power generation unit through the wires.

[0009] Furthermore, the present invention also includes a power generation magnetic field unit, and the power generation magnetic field unit is arranged on the hull.

[0010] Furthermore, in the present invention, the power generation magnetic field unit includes a plurality of permanent magnets distributed in an array.

[0011] Furthermore, in the present invention, the output end of the conductor is connected to a current wiring, and the current wiring is connected to a power generation unit.

[0012] Furthermore, in the present invention, a roller is provided at the lower end of the permanent magnet, and the roller is slidably connected to the track.

[0013] Furthermore, in the present invention, four rollers are provided.

[0014] Furthermore, in the present invention, the track is rigidly connected to the hull.

[0015] Furthermore, in the present invention, the track is welded to the hull or connected with bolts.

[0016] Furthermore, in the present invention, the track is installed below the deck in the hull.

[0017] The present invention also discloses a method for generating electricity for a marine vessel, comprising the following steps:

[0018] The permanent magnet is slidably mounted on the track;

[0019] When the ship is sailing, the fluctuation of the waves drives the ship to bump back and forth, and the permanent magnet slides back and forth along the track;

[0020] The permanent magnet generates electrical energy during the sliding process, which is transmitted to the power generation unit through the wire. The power generation unit stores or converts the acquired electrical energy for use.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The invention discloses a power generation system for marine vessels, wherein a track is arranged on the hull, and the track is used as a carrier for the sliding of permanent magnets. When the vessel is sailing at sea, the vessel will be bumpy under the drive of the waves, and the thrust generated by the bumps will drive the permanent magnets to reciprocate along the track. During the movement, electric energy is generated, and the electric energy is transmitted to the power generation unit through a wire. The power generation system can continuously generate electric energy during navigation, provide additional energy support for the vessel, improve the energy self-sufficiency rate, reduce the dependence on external energy, and use natural physical phenomena to generate electricity without additional fuel costs and maintenance costs. When the vessel encounters an energy supply interruption or an emergency, it can rely on its own power generation capacity to maintain basic operation, thereby enhancing the autonomy and flexibility of the vessel. The demand of the vessel for performing remote tasks is met, and at the same time, the power generation system, as a backup or auxiliary energy source, can provide the vessel with necessary power support at critical moments to ensure the navigation safety and stability of the vessel.

[0023] Furthermore, the present invention also includes a power generation magnetic field unit, which is arranged on the hull. The power generation magnetic field unit provides a strong magnetic field environment for the sliding of the permanent magnet on the track, making the permanent magnet magnetic field more efficient, thereby improving the conversion efficiency of electric energy and increasing the energy output capacity.

[0024] Furthermore, in the present invention, the power generation magnetic field unit includes a plurality of permanent magnets distributed in an array, which can ensure the uniformity and stability of the magnetic field distribution. The permanent magnets distributed in an array can form a more uniform and powerful magnetic field environment, so that the interaction between the permanent magnets and the magnetic field when sliding on the track is more sufficient and efficient, providing more power support for the ship.

[0025] Furthermore, in the present invention, the output end of the conductor is connected to the current wiring, and the current wiring is connected to the power generation unit. The close connection between the conductor and the current wiring ensures the high efficiency of the electric energy during the transmission process, reduces resistance and energy loss, and enables the electric energy generated by the movement of the permanent magnet in the magnetic field to be more efficiently transmitted to the power generation unit for conversion and utilization.

[0026] Furthermore, in the present invention, a roller is disposed at the lower end of the permanent magnet, and the roller is slidably connected to the track. The roller can reduce the friction and wear generated during direct contact, thereby extending the service life of the permanent magnet and the track.

[0027] Furthermore, in the present invention, the track is rigidly connected to the hull, which ensures the stability of the power generation system during the movement of the ship, reduces the impact of the ship's shaking or tilting on the power generation system, and improves the reliability of the system and the stability of the power output.

[0028] Furthermore, in the present invention, the track is installed below the deck in the hull, which can effectively prevent direct erosion of the track by environmental factors such as seawater, salinity, and ultraviolet rays, effectively extend the service life of the track, and reduce the frequency of maintenance and replacement.

[0029] The present invention also discloses a method for generating electricity for marine vessels. By installing such a power generation system on a vessel, the self-sufficiency of the vessel can be significantly improved. In areas far away from land or not covered by the power grid, the vessel can rely on its own power generation system to meet energy needs, reducing dependence on external energy. Since the method uses natural physical phenomena to generate electricity, no additional fuel costs and maintenance costs are required. When the vessel encounters an energy supply interruption or emergency, it can rely on its own power generation capacity to maintain basic operations, thereby enhancing the autonomy and flexibility of the vessel. The vessel's needs for performing remote missions are met, and at the same time, the power generation system, as a backup or auxiliary energy source, can provide the vessel with necessary power support at critical moments to ensure the vessel's navigation safety and stability.

[0039] The present invention is further described in detail below in conjunction with the accompanying drawings:

[0040] See also Figure 1The embodiment of the present invention discloses a power generation system for marine vessels, which is mainly used to solve the problem that when the vessel is operating at sea, it is often difficult for the vessel to go to the preset marine supply station for power replenishment as planned due to the complex and changeable marine environment and special sea conditions. This not only affects the operating efficiency of the vessel, but also poses a serious threat to the safety of the vessel, affecting the navigation stability, navigation accuracy and emergency response capabilities of the vessel in emergency situations. In this system, when the vessel is sailing against the waves in strong winds and waves, the bow and the houseboat alternately bump, and the magnetic field and the application coil move relative to each other to generate current, which can continuously generate current for power generation, store the electricity or transmit it with a wire to generate electricity. In this system, the permanent magnet has an N pole and an S pole, and four wheels are installed on it. As the bow and stern of the hull are raised and lowered, they can move left and right along the track, and the raising and lowering generate reciprocating motion. The moving magnetic field continuously cuts the wires set up on the track, so as to generate current, which is stored in the battery or led out with a wire, so as to generate electricity.

[0041] Specifically, the system includes the following structure:

[0042] Example 1

[0043] The present embodiment discloses a power generation system for a marine vessel, including a hull 6, on which a plurality of adjacent tracks 3 are arranged, on which permanent magnets 1 are slidably connected, and between which a plurality of adjacent tracks 3 are arranged conductive wires 2, which are connected to a power generation unit; when the permanent magnets 1 slide along the tracks 3, electric energy is generated, and the electric energy is transmitted to the power generation unit through the conductive wires 2.

[0044] Furthermore, in the embodiment of the present invention, a number of adjacent tracks 3 are distributed in parallel or arranged at a specific angle to maximize the path length of the permanent magnet sliding, thereby improving the power generation efficiency.

[0045] At the same time, adjacent rails 3 should be installed with proper spacing to accommodate the permanent magnets and the conductors and ensure the stability of the system operation.

[0046] Furthermore, in the embodiment of the present invention, the permanent magnet 1 is made of high-performance rare earth permanent magnet material, which has the characteristics of strong magnetic field and good stability. At the same time, the structure of the permanent magnet 1 can be cylindrical or rectangular.

[0047] Furthermore, in an embodiment of the present invention, the conductor 2 is made of a highly conductive material, such as copper or silver alloy, and has good corrosion resistance and wear resistance. Specifically, when arranged between the rails 3, the conductor 2 forms a closed loop or a specific pattern to collect the electrical energy generated when the permanent magnet slides.

[0048] Furthermore, in an embodiment of the present invention, the power generation unit converts the alternating current collected in the wire into stable direct current or alternating current, and adjusts the voltage and current to meet the power demand of the ship or stores it in a battery. The existing power generation unit can meet the needs of this system, and the power generation unit may include electronic devices such as rectifiers, filters or transformers.

[0049] Furthermore, in an embodiment of the present invention, the track is made of corrosion-resistant materials, such as stainless steel or special alloys, to ensure long-term use in the marine environment without damage. At the same time, the track is designed to be a straight line or a curved shape, and can be flexibly arranged according to the ship layout and power generation needs.

[0050] In this embodiment, a track is arranged on the hull, and the track serves as a carrier for the sliding of the permanent magnet. When the ship is sailing on the sea, the ship will be bumpy under the drive of the waves, and the thrust generated by the bump will push the permanent magnet to reciprocate along the track. During the movement, electric energy is generated, and the electric energy is transmitted to the power generation unit through the wire. The power generation system can continuously generate electric energy during navigation, provide additional energy support for the ship, improve energy self-sufficiency, and reduce dependence on external energy. It uses natural physical phenomena to generate electricity without additional fuel costs and maintenance costs. When the ship encounters energy supply interruption or emergency, it can rely on its own power generation capacity to maintain basic operation, thereby enhancing the autonomy and flexibility of the ship. It meets the needs of the ship for performing remote tasks. At the same time, the power generation system, as a backup or auxiliary energy source, can provide the ship with necessary power support at critical moments to ensure the safety and stability of the ship's navigation.

[0051] Example 2

[0052] The present embodiment discloses a power generation system for a marine vessel, including a hull 6, on which a plurality of adjacent tracks 3 are arranged, on which permanent magnets 1 are slidably connected, and between which a plurality of adjacent tracks 3 are arranged conductive wires 2, which are connected to a power generation unit; when the permanent magnets 1 slide along the tracks 3, electric energy is generated, and the electric energy is transmitted to the power generation unit through the conductive wires 2; the system also includes a power generation magnetic field unit, which is arranged on the hull 6.

[0053] Furthermore, in the embodiment of the present invention, in order to maximize the use of the flow of seawater 7 and the kinetic energy of waves, a power generation magnetic field unit can be installed at the bottom of the hull, so as to ensure that the permanent magnet can cut the strong magnetic field generated by the power generation magnetic field unit when sliding, thereby generating more electrical energy.

[0054] Furthermore, in the embodiment of the present invention, the power generation magnetic field unit can also be installed on the side of the hull to capture the energy of the ocean current and waves from the side and provide additional power generation power for the system.

[0055] Furthermore, in the embodiment of the present invention, the power generation magnetic field unit can also be installed in a dedicated cabin below the deck.

[0056] In this embodiment, the power generation magnetic field unit can enhance the electromagnetic induction effect between the permanent magnet and the wire during the sliding process, thereby significantly improving the power generation efficiency. By precisely controlling the magnetic field strength and direction, the kinetic energy of the permanent magnet can be maximized and converted into electrical energy. The power generation magnetic field unit adopts a non-contact energy conversion method, which reduces mechanical wear and friction loss, thereby reducing the maintenance cost and failure rate of the system.

[0057] Example 3

[0058] The present embodiment discloses a power generation system for a marine vessel, comprising a hull 6, on which a plurality of adjacent tracks 3 are arranged, on which permanent magnets 1 are slidably connected, and between which a plurality of adjacent tracks 3 a conductive wire 2 is arranged, and between which a power generation unit is connected; when the permanent magnet 1 slides along the track 3, electric energy is generated, and the electric energy is transmitted to the power generation unit through the conductive wire 2; the power generation magnetic field unit is also included, and the power generation magnetic field unit is arranged on the hull 6, and the power generation magnetic field unit includes a plurality of permanent magnets distributed in an array.

[0059] Furthermore, in an embodiment of the present invention, the permanent magnets 1 can be arranged linearly along the length direction of the hull 6 to form one or more parallel permanent magnet chains. This array method is simple and direct, easy to install and maintain, and can effectively utilize the relative motion generated by the hull movement to generate electricity.

[0060] Furthermore, in the embodiment of the present invention, the permanent magnets 1 can be arranged in a ring around a certain center point or axis of the hull to form one or more permanent magnet rings. This array method can produce a more uniform magnetic field distribution, improve power generation efficiency, and be more adaptable to the movement of the hull.

[0061] Furthermore, in an embodiment of the present invention, the permanent magnets 1 can be arranged on the hull in a spiral shape. This innovative approach combines the characteristics of linear and annular shapes, and can produce more complex magnetic field changes during the movement of the hull, thereby potentially improving power generation efficiency and reducing energy losses.

[0062] Furthermore, in an embodiment of the present invention, during installation, the permanent magnet 1 can be directly embedded into the structural material of the hull 6, such as the deck, hull or internal support structure, which can ensure the stability and safety of the permanent magnet, but the installation and maintenance are more difficult.

[0063] Furthermore, in the embodiment of the present invention, the permanent magnet can also be installed independently and fixed to the hull by bolts.

[0064] By optimizing the array and installation methods of permanent magnets, the movement of the ship and ocean energy resources can be more effectively utilized, thereby improving the energy conversion efficiency of the power generation system.

[0067] Furthermore, in the embodiment of the present invention, the roller 4 can be fixed to the lower end of the permanent magnet 1 by bolt connection to form an integral component.

[0068] Furthermore, in the embodiment of the present invention, the roller 4 and the permanent magnet 1 may also be connected by a buckle or a latch, adopting a detachable connection method.

[0069] Furthermore, in the embodiment of the present invention, the sliding connection structure between the roller and the track enables the power generation system to better adapt to different sea conditions and wave conditions. Whether in calm sea or turbulent waves, the system can maintain stable operation.

[0071] The present embodiment discloses a power generation system for a marine vessel, including a hull 6, on which a plurality of adjacent tracks 3 are arranged, on which permanent magnets 1 are slidably connected, and between which a plurality of adjacent tracks 3 are arranged conductive wires 2, which are connected to a power generation unit; when the permanent magnets 1 slide along the tracks 3, electric energy is generated, and the electric energy is transmitted to the power generation unit through the conductive wires 2; a roller 4 is arranged at the lower end of the permanent magnet 1, and the roller 4 is slidably connected to the tracks 3, and four rollers 4 are arranged.

[0072] Furthermore, in the embodiment of the present invention, the design of the four rollers can more evenly disperse the gravity and dynamic force generated by the permanent magnet during movement, which helps to reduce vibration and shaking, enhance the stability and balance of the entire power generation system, and ensure stable operation even in complex sea conditions.

[0073] Example 6

[0074] The present embodiment discloses a power generation system for a marine vessel, including a hull 6, on which a plurality of adjacent tracks 3 are arranged, on which permanent magnets 1 are slidably connected, and between which a plurality of adjacent tracks 3 are arranged conductive wires 2, which are connected to a power generation unit; when the permanent magnets 1 slide along the tracks 3, electric energy is generated, and the electric energy is transmitted to the power generation unit through the conductive wires 2, and the tracks 3 are rigidly connected to the hull 6, and the tracks 3 are welded to the hull 6 or connected by bolts.

[0075] Furthermore, in the embodiment of the present invention, the welding connection provides a strong structural strength, which can withstand the huge loads brought by the complex offshore environment (such as wind and waves, tides, etc.), and ensure the stable operation of the power generation system.

[0076] Further, in the embodiment of the present invention, in the bolt connection, corresponding holes are pre-opened on the track 3 and the hull 6, and then the bolts are passed through the holes and tightened with nuts to achieve the connection between the two. The bolt connection can be disassembled and replaced as needed.

[0077] Furthermore, in the embodiment of the present invention, a reinforcing plate or reinforcing ribs may be provided at the connection between the track 3 and the hull 6 to improve the strength and rigidity of the connection portion.

[0078] Furthermore, in the embodiment of the present invention, the cross-sectional shape of the track 3 may be I-shaped, H-shaped or box-shaped, providing greater bending stiffness and load-bearing capacity.

[0079] Example 7

[0080] The present embodiment discloses a power generation system for a marine vessel, including a hull 6, on which a plurality of adjacent tracks 3 are arranged, on which permanent magnets 1 are slidably connected, and between which a plurality of adjacent tracks 3 are arranged conductive wires 2, which are connected to a power generation unit; when the permanent magnets 1 slide along the tracks 3, electric energy is generated, and the electric energy is transmitted to the power generation unit through the conductive wires 2, and the tracks 3 are installed below the deck in the hull 6.

[0081] In the embodiment of the present invention, the track is installed under the deck, which can more effectively utilize the internal space of the hull, and at the same time effectively protect it from the direct impact of severe weather conditions at sea (such as strong winds, big waves, sea water splashing, etc.), reducing the risk of damage to the track due to corrosion, wear or physical impact, thereby extending the service life of the track.

[0082] Example 8

[0083] The present embodiment discloses a method for generating electricity for marine vessels, comprising the following steps: a permanent magnet 1 is slidably mounted on a track 3; when the vessel is sailing, the fluctuation of the waves drives the vessel to bump back and forth, and at this time the permanent magnet 1 slides back and forth along the track 3; the permanent magnet 1 generates electrical energy during the sliding process, and the electrical energy is transmitted to a power generation unit through a wire 2, and the power generation unit stores or converts the acquired electrical energy for use.

[0084] The method disclosed in this embodiment directly uses the fluctuation of the sea waves as a power source, without the need for additional fuel or external energy input. This method reduces dependence on fossil fuels, reduces ship operating costs and environmental pollution, and the ship can generate electricity by itself during navigation to meet the power needs of shipboard equipment, lighting, communications, etc. This improves the self-sufficiency of the ship and enhances its survivability and operating efficiency when far away from land.

[0085] Furthermore, compared with traditional wave energy power generation devices, the permanent magnet sliding power generation system in this method has a relatively simple structure, fewer moving parts, and less noise and vibration during the power generation process, which helps to improve the crew's work comfort and the ship's navigation stability. The magnet sliding power generation system can better adapt to the fluctuations of the waves, and through the guidance and support of the track, it reduces the direct impact on the power generation system.
