Abstract
Description
Technical Field
[0001] This invention relates to the field of new energy power supply technology for marine monitoring equipment, and more specifically, to a self-powered marine drifting buoy that converts wave kinetic energy and solar energy into electrical energy. Background Technology
[0002] In the field of buoy equipment mainly used for marine environmental monitoring, discardable self-powered drifting buoys have excellent characteristics such as small size, light weight, long endurance, and low maintenance frequency, making them a suitable replacement for anchored large environmental monitoring buoys that are difficult to cast, install, maintain frequently, and have limited monitoring range. Commonly used discardable self-powered drifting buoys either suffer from a reliance on a single energy source, often using pure solar power, which fails in cloudy or rainy weather, or relies on battery replacement, resulting in high maintenance costs for batteries and photovoltaic panels; or they suffer from low wave kinetic energy conversion efficiency. These issues lead to poor power supply continuity, low energy conversion efficiency, and insufficient environmental adaptability in complex sea conditions. Summary of the Invention

[0070] In one embodiment of the present invention, after the wave kinetic energy capture and electrical energy conversion device 5 is assembled as a whole, the remaining extension rod 5-5 and small heavy ball 5-6 are not assembled for the time being. The wave kinetic energy capture and electrical energy conversion device 5 in this state is placed into the spherical cavity, and the four small cylindrical protrusions on the bottom surface of the bottom shell 5-1 of the wave kinetic energy capture and electrical energy conversion device 5 are aligned with the four concave cylindrical holes 4-2 on the top surface of the insertion mounting plate assembly 4. The small heavy ball 5-6 is installed on the end of the extension rod 5-5, and the threaded hole of the small heavy ball 5-6 is connected to the stud at the end of the extension rod 5-5 and screwed in. The small heavy ball 5-6 is made of high-density metal, such as tungsten. The extension rod 5-5, along with the small heavy ball 5-6, is placed into the sphere cavity. The threaded hole at the end of the extension rod 5-5 aligns with the stud at the outer end of the horizontal shaft 5-4, and is screwed in for fixation. After the upper mounting plate assembly 6 is connected to the sphere cover 7, it is inserted into the sphere cavity. The concave holes on the bottom surface of the four connecting pillars 6-2 at the bottom of the upper mounting plate assembly 6 are aligned with the four small cylindrical bosses on the top surface of the outer shell 5-1 of the wave kinetic energy capture and conversion device 5, and inserted. The sphere cover 7 is then fixed to the sphere shell 1 with screws. The wave kinetic energy capture and conversion device 5 is installed between the middle mounting plate assembly 4 and the upper mounting plate assembly 6. Horizontal position constraint, vertical support, and clamping fixation are achieved through the alignment of the four pairs of bosses and concave holes.
[0071] In one embodiment of the invention, the wave kinetic energy capture and electrical energy conversion device 5 is installed inside the spherical cavity. When the entire buoy sphere floats on the sea surface and is affected by wave motion, the buoy sphere fluctuates up and down, sways left and right, and randomly rotates with the waves. The wave kinetic energy capture and electrical energy conversion device 5 inside the spherical cavity moves along with the buoy sphere. The lever arm composed of the small heavy ball 5-6, the extension rod 5-5, and the horizontal axis 5-4, due to inertia, will rotate irregularly around the central axis of the main axis 5-3 relative to the buoy sphere as the entire device moves irregularly with the waves. The direction of rotation is random, and the rotation speed is determined by the magnitude of the wave kinetic energy. The pulley frame 5-7 and the pulley wheel 5-8 provide support for the rotational movement of the lever arm assembly of the small heavy ball 5-6, reducing motion resistance and restraining the tendency to tilt up and down. The main shaft 5-3 rotates with the lever arm assembly of the small ball 5-6. The inner ring of the overrunning clutch assembly 5-10 rotates with the main shaft 5-3. Two sets of outer rings of the overrunning clutch assemblies 5-10 are symmetrically mounted, one of which rotates with the inner ring, while the other does not. The secondary shaft 5-11 rotates with the outer ring of the overrunning clutch assembly 5-10. Through the one-way transmission characteristic of the overrunning clutch, when the main shaft 5-3 rotates forward, the upper secondary shaft 5-11 rotates forward with the main shaft 5-3 under the one-way transmission of the overrunning clutch assembly 5-10, while the lower secondary shaft 5-11 does not rotate. When the main shaft 5-3 rotates in reverse, the lower secondary shaft 5-11 rotates in reverse with the main shaft 5-3 under the one-way transmission of the overrunning clutch assembly 5-10, while the upper secondary shaft 5-11 does not rotate. The large gear 5-12 rotates with the countershaft 5-11, the two small gears 5-16 on the same side rotate with the large gear 5-12, the side shaft 5-15 rotates with the small gears 5-16, the large bevel gear 5-17 rotates with the side shaft 5-15, the small bevel gear 5-19 rotates with the large bevel gear 5-17, and the generator set 5-20 shaft rotates with the small bevel gear 5-19. The generator set 5-20 rotates to generate electricity. Under the action of the unidirectional transmission mechanism, the generator set 5-20 on the same side maintains a constant rotation direction, thus the direction of the generated current does not change. This eliminates the need for current rectification, making it easier to plan the collection and storage of electrical energy, reducing circuit failure rates and energy consumption. The generator uses a permanent magnet brushless high-speed generator, resulting in high kinetic energy to electrical energy conversion efficiency. The generator set 5-20 outputs a constant-direction power supply to circuit board group 3 of the dual-energy intelligent management circuit board. Through intelligent control planning, it replenishes the battery pack 9, maintaining the equipment's operating range.

The upper mounting plate 6-1 is clamped by the connecting post 6-2 and the inner bottom cylindrical platform of the spherical cover 7, thus connecting the upper mounting plate assembly 6 and the spherical cover 7 with the connecting post 6-2. The Beidou antenna 6-4 is used to transmit meteorological and hydrological information collected by the equipment, as well as equipment status information, including positioning, power level, and charging / discharging status, via Beidou satellite communication.

[0074] like Figure 13 As shown, Figure 13 This is a three-view drawing and axonometric drawing of a solar panel assembly for a self-powered marine drifting buoy that converts wave kinetic energy and solar energy into electrical energy, according to an embodiment of the present invention. The solar panel assembly 8 consists of multiple monocrystalline silicon high-efficiency solar cells, manufactured using superior processes, resulting in lightweight, high strength, good sealing, corrosion resistance, easy cleaning by rainwater, and resistance to adhesion. The solar panel assembly 8 is installed at a certain angle around the outside of the spherical shell 1, secured by a snap-fit structure between the spherical shell 1 and the spherical cover 7, using 3M adhesive. Each charging cable connects to the spherical cavity through a waterproof joint hidden behind the solar panel assembly 8, ensuring a robust and reliable sealing process and excellent airtightness within the spherical cavity. The solar panel assembly 8 is angled towards the unobstructed sky at multiple angles to efficiently collect solar energy, converting it into electrical energy to replenish the buoy system's battery and maintain the equipment's operating range.
