Description
Technical Field:
[0001] The present invention relates to an ocean observation buoy powered by a magnetic levitation multi-stable wave energy generation device. Background Art:
[0002] Ocean observation buoys are important tools for understanding and managing the ocean. They can collect important hydrological, water quality, and meteorological data for ocean scientific research, offshore oil and gas development, national defense construction, and other ocean operations. Providing stable and reliable power supply is a necessary condition for ocean observation buoys to work continuously and all-weather for a long time.
[0003] Traditional ocean observation buoys are powered by batteries, wind energy, or solar energy. Battery power supply requires frequent battery replacement, increasing the operation and maintenance costs of the buoy; the harsh ocean environment, with high salinity and humidity, will damage the wind turbines and affect the normal operation of the device; solar energy has intermittent characteristics and is greatly affected by weather, and cannot output stable electrical energy at night and on cloudy days.
[0004] Due to various defects and problems of the above-mentioned multiple types of energy in practical applications, wave energy generation can be selected as the main power supply method for ocean observation buoys. Wave energy has the advantages of high energy density, large total reserves, and long working hours, and can generate electricity more than 90% of the time. Powering ocean exploration buoys through wave energy can provide stable, reliable, and efficient power supply for ocean environmental monitoring operations.
[0005] The existing permanent magnet oscillators built in ocean observation buoys have poor motion response characteristics, and the motion amplitude is limited, resulting in a low overall output power of electrical energy. The linear motor has a large running damping, so that the wave energy generation device cannot provide stable and reliable power supply for ocean observation buoys, and the overall operation reliability is poor, and the maintenance cost is high. Summary of the Invention:

DETAILED DESCRIPTION OF THE EMBODIMENTS:
[0022] To clearly illustrate the technical features of this solution, the present invention will be elaborated in detail below through specific embodiments and in conjunction with its accompanying drawings.
[0023] As Figures 1-4 shown in
[0024] Buoy monitoring component, which is used to monitor and obtain various types of relevant information data of the ocean observation buoy, and perform remote transmission and indication. It includes an environmental monitoring sensor 2, a communication module 1, and a signal indicator light 3. The buoy monitoring component is installed on the upper part of the floating body 6 through a monitoring support frame 4;
[0025] Power supply component, which is used to provide stable and lasting power supply for the ocean observation buoy. It includes a solar panel 5, a power generation cabin 7, and a maglev multi-stable wave energy generation device 8. The power generation cabin is installed at the lower part of the floating body 6, and the maglev multi-stable wave energy generation device 8 is installed inside the power generation cabin through two columns 802.
[0026] The maglev multi-stable wave energy generation device includes an upper floating magnet 801 and a lower floating magnet 810. The upper floating magnet 801 and the lower floating magnet 810 are respectively connected to both ends of the power generation channel 805 through an upper bushing 804 and a lower bushing 809 to ensure the fixed positions of the upper floating magnet 801 and the lower floating magnet 810; A power generation coil 806 is installed in the groove on the outer surface of the power generation channel 805, and a vibrating magnet 812 is arranged inside; Both the upper floating magnet 801 and the lower floating magnet 810 provide repulsive forces for the vibrating magnet 812, so that the vibrating magnet 812 can stably float at the middle balance position of the power generation channel 805.
[0027] A plurality of multi-stable magnets 807 are evenly arranged in the middle outside the power generation channel 805. The multi-stable magnets 807 are installed on a magnet support plate 808, and the magnet support plate 808 is fixedly connected to the two columns 802; The multi-stable magnets 807 have the same magnetic pole direction as the vibrating magnet 812 to change the stiffness of the vibrating magnet 812, further balance the potential energy of the wave energy generation device, and make the vibrating module 812 exhibit non-linear multi-stable characteristics.
[0028] Air circulation holes are respectively provided on the power generation channel 805, the upper bushing 804, and the lower bushing 809 to increase the air circulation between the power generation channel 805 and the outside world and reduce the temperature inside the power generation channel 805.
[0029] The upper floating magnet 801 and the lower floating magnet 810 have the same magnetic pole direction, and their magnetic pole directions are opposite to that of the vibrating magnet 812.
[0030] The power generation coil 806 generates an alternating current in a reciprocally changing magnetic field, and outputs direct current after being rectified by a power conversion module. The electric energy output by the maglev multi-stable wave energy generation device 8 and the solar panel 5 is stored in the storage battery to provide continuous and reliable power guarantee for the normal operation of the buoy monitoring part.
[0031] The working principle of the ocean observation buoy powered by the magnetic levitation multi-stable wave energy generation device in the embodiments of the present invention is as follows: Integrate the magnetic levitation multi-stable wave energy generation device inside the power generation cabin of the ocean observation buoy to avoid the corrosion of key power generation components by the harsh marine environment with high salinity and high humidity, improve the overall reliability of the device operation, use magnetic levitation technology to replace the traditional mechanical transmission connection, reduce mechanical losses, improve the starting performance of the device, and at the same time introduce a non-linear stiffness mechanism to broaden the power generation frequency band, providing continuous and stable power supply for the ocean observation buoy, thereby reducing the daily operation and maintenance costs and ensuring that the ocean observation buoy can work stably for a long time.
[0032] A wave energy generation device is a power generation device that uses the energy of waves to produce electrical energy. According to the differences in the energy intermediate conversion links, it can be divided into three categories: mechanical type, pneumatic type, and hydraulic type; in actual application scenarios, there will be various problems when other types of energy are used to supply power to ocean observation buoys, so wave energy is selected as the main power supply energy.
[0033] In the overall scheme, it mainly includes:
[0034] A buoy monitoring component, used to monitor and obtain various types of relevant information data of the ocean observation buoy and perform remote transmission and indication, including environmental monitoring sensors, communication modules, and signal indicators. The buoy monitoring component is installed on the upper part of the floating body through a monitoring support frame;
[0035] A power supply component, used to provide stable and lasting power supply for the ocean observation buoy, including solar panels, a power generation cabin, and a magnetic levitation multi-stable wave energy generation device. The power generation cabin is installed at the lower part of the floating body, and the magnetic levitation multi-stable wave energy generation device is installed inside the power generation cabin through two columns.
[0036] The buoy monitoring component and the power supply component are respectively arranged above and below the floating body, making full use of the space of the entire device. On the premise of ensuring the functionality of the ocean observation buoy, the overall structure of the ocean observation buoy is made as compact as possible to adapt to the complex and changeable marine environment.
[0037] Specifically, the environmental monitoring sensors can be, but are not limited to, wave height sensors, temperature sensors, humidity sensors, salinity sensors, etc., which can accurately monitor and obtain various types of marine environment information; and the communication module can select a Beidou communicator or a wireless transceiver, which can accurately remotely transmit the various types of marine environment information obtained by monitoring.
[0038] For the power supply component, the power generation cabin and the floating body form a sealed space, completely isolating the magnetic levitation multi-stable wave energy generation device from seawater, avoiding the impact, corrosion, etc. of the high-salinity and high-humidity marine environment on the power generation components, so as to ensure continuous and stable power supply.
[0039] Furthermore, the magnetic levitation multi-stable wave energy power generation device includes an upper levitation magnet and a lower levitation magnet. The upper levitation magnet and the lower levitation magnet are respectively connected to both ends of the power generation channel through an upper ferrule and a lower ferrule. In order to ensure the fixed positions of the upper levitation magnet and the lower levitation magnet, the levitation magnets are fixed at specific positions on the column by using an upper fixing buckle and a lower fixing buckle; a power generation coil is installed in the groove on the outer surface of the power generation channel, and a vibration magnet is arranged inside it. The magnetic pole directions of the upper levitation magnet and the lower levitation magnet are the same, and their magnetic pole directions are opposite to that of the vibration magnet.
[0040] During the working process, both the upper levitation magnet and the lower levitation magnet provide repulsive forces for the vibration magnet, enabling the vibration magnet to levitate at the middle equilibrium position of the power generation channel. When the floating body undergoes undulating motion under the excitation of waves, the vibration magnet is disturbed to generate reciprocating vibrations, causing the magnetic field around the power generation coil to change, and thus an induced current is generated in the power generation coil.
[0041] The stiffness of the vibration magnet is changed by the action of the multi-stable magnet, further balancing the potential energy of the wave energy power generation system, making the system exhibit multiple stable equilibrium points, which is beneficial to expanding the amplitude of the vibration magnet and broadening the power generation frequency bandwidth; the multi-stable magnets are evenly arranged in the middle outside the power generation channel and are fixedly connected to the column through a magnet support plate, and the overall structure connection is stable and reliable.
[0042] During the power generation process, the vibration magnet will generate certain eddy current losses, and thus generate certain heat, causing the temperature inside the power generation channel to rise, further reducing the power generation efficiency. By opening air circulation holes, the air circulation between the power generation channel and the outside is increased, the temperature inside the power generation channel is reduced, and the normal operation of the power generation work is ensured.
[0043] The power generation coil generates an alternating current in the reciprocating changing magnetic field, and after being rectified by the power conversion module, a direct current is output. The electric energy output by the magnetic levitation multi-stable wave energy power generation device and the solar panel is stored in the storage battery, providing continuous and reliable power guarantee for the normal operation of the buoy monitoring part.
[0044] It should be particularly noted that other functional modules such as the power change module and the communication module can be integrally connected to the controller for unified control. When an abnormal situation occurs, it can be triggered by the unified control of the controller in a timely manner to quickly solve the fault or abnormal situation.
[0045] In summary, the ocean observation buoy powered by the magnetic levitation multi-stable wave energy generation device in the embodiments of the present invention integrates the magnetic levitation multi-stable wave energy generation device inside the power generation cabin of the ocean observation buoy, avoiding the corrosion of key power generation components in the harsh marine environment of high salinity and high humidity, improving the overall reliability of the device operation. The magnetic levitation technology is used to replace the traditional mechanical transmission connection, reducing mechanical losses and improving the starting performance of the device. At the same time, a non-linear stiffness mechanism is introduced to broaden the power generation frequency bandwidth, providing continuous and stable power supply for the ocean observation buoy, thereby reducing the daily operation and maintenance costs and ensuring that the ocean observation buoy can work stably for a long time.
[0046] The above specific implementation manners cannot be used as a limitation to the protection scope of the present invention. For those skilled in the art of this technology, any alternative improvement or transformation made to the embodiments of the present invention falls within the protection scope of the present invention.
[0047] Where the present invention is not described in detail, it is the well-known technology of those skilled in the art of this technology.
