Description

Technical Field

[0001] This invention relates to the field of marine buoy technology, specifically to a wave energy power generation device applied to marine buoys. Background Technology

[0002] Ocean buoys play an irreplaceable role in marine environmental monitoring, weather warning, shipping support, and marine resource development, and their continuous and stable operation depends on a reliable energy supply. Currently, the power supply methods for ocean buoys have significant limitations: traditional battery power requires regular replacement, which not only consumes a lot of manpower and resources in open sea areas but may also lead to equipment downtime due to untimely replacement; solar power is significantly affected by weather and day-night cycles, and its stability is difficult to guarantee in situations of continuous rain, high-latitude polar nights, or when sunlight is blocked at sea. Wave energy, as a renewable energy source abundant in the ocean, has the characteristics of high energy density, wide distribution, and is not limited by day-night cycles or weather conditions, making it an ideal energy source for powering ocean buoys.

[0003] In the marine environment, various marine organisms such as barnacles, shellfish, and algae easily adhere to the surface of buoys in large quantities. This not only increases the weight and drag of the buoys and reduces their motion response performance, but also directly affects the wave energy capture efficiency, resulting in a significant decrease in the output power of the power generation device. Existing cleaning methods have obvious drawbacks: manual cleaning requires the buoys to be retrieved to the shore, which is cumbersome and costly, and is especially unsuitable for offshore buoys; although chemical antifouling agents can inhibit biological attachment in the short term, they will cause serious pollution to the marine ecological environment and do not meet the requirements of green environmental protection.

[0004] Therefore, a wave energy power generation device for use on ocean buoys is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a wave energy generation device for marine buoys, so as to solve the problem mentioned in the background art that marine organisms attached to the buoys are difficult to clean in a timely manner.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wave energy power generation device for marine buoys, comprising a buoy base component and a buoy-mounted component installed on top of the buoy base component. At least one set of float-type power generation mechanisms is installed on the outer side of the buoy base component to generate electricity using wave energy. Each float-type power generation mechanism includes a mounting portion fixedly installed on the outer side of the buoy base component. A float is rotatably connected inside the mounting portion via a connecting shaft and a connecting frame. The device also includes...

[0007] A follow-up cleaning mechanism is correspondingly installed on a set of float-type power generation mechanisms and used in conjunction with the set of float-type power generation mechanisms. It is used to clean marine organisms attached to the set of float-type power generation mechanisms by using the floating of the set of float-type power generation mechanisms. The follow-up cleaning mechanism includes a telescopic rod that is rotatably connected to the mounting part and the connecting frame through an ear plate to convert the force of the float floating up and down with the waves into compressive energy. The float is equipped with a multi-stage telescopic rod that is connected to the telescopic rod through a conduit. The output end of the multi-stage telescopic rod is fixedly connected to a cleaning plate. The multi-stage telescopic rod receives the compressive energy converted by the telescopic rod through the conduit to realize the reciprocating scraping of the cleaning plate.

[0008] Preferably, it also includes a storage mechanism installed inside the mounting section and fixedly connected to the telescopic rod via an output shaft. The buoy base component is also provided with an energy storage component that recovers and replenishes the compressed energy inside the telescopic rod and the multi-stage telescopic rod, so as to adjust the length of the telescopic rod and the multi-stage telescopic rod and to adjust the angle of the float by rotating the telescopic rod.

[0009] Preferably, the buoy is equipped with a wind speed monitor to monitor the wind speed at the location of the buoy in real time.

[0010] Preferably, the mounting part has a through groove that communicates with the inside of the buoy base component. The buoy base component has a power generation component inside. One end of the connecting shaft passes through the inside of the through groove, and this end of the connecting shaft is connected to the rotor on the power generation component via a belt pair.

[0011] Preferably, the buoy base component is further provided with a collection component, which includes an inverter and a battery. A wire is provided between the power generation component and the inverter, and the inverter and the battery are electrically connected.

[0012] Preferably, the surface of the float is etched with spiral guide grooves, which guide the water flow to form a directional vortex to wash away the organisms attached to the surface when the float moves.

[0013] Preferably, the energy storage component includes a pump body with a controller, an energy storage tank, a housing, and a horizontal flow tank. One end of the pump body is connected to the energy storage tank, and the other end of the pump body is connected to the horizontal flow tank. The horizontal flow tank is connected to the telescopic rod and the multi-stage telescopic rod through a conduit. The energy storage tank includes a fixed part fixedly connected to the housing and an expansion part disposed on the upper end of the fixed part and connected to the fixed part.

[0014] Preferably, a protective sleeve is fixedly connected to the outside of the float, and the protective sleeve covers the connection between the guide tube and the multi-stage telescopic rod.

[0015] Preferably, the float has a connecting groove, the multi-stage telescopic rod is installed in the connecting groove, and the top of the cleaning plate has a groove.

[0016] Preferably, the mounting part has a storage groove inside, and the telescopic rod is set inside the storage groove.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention achieves stable wave energy conversion through a float-type power generation mechanism. As the float rotates up and down with the waves, it drives the connecting shaft to rotate via a connecting frame. The motion is transmitted to the power generation component via a belt, causing it to cut magnetic field lines and generate electricity. This electricity is then converted into stable DC power by the inverter in the collection component and stored in a battery. This allows for continuous power supply to the buoy's electronic equipment regardless of day or night or weather conditions, solving the problem of unstable traditional solar power supply and significantly improving the sustainability of the buoy's energy supply.

[0019] 2. This invention achieves highly efficient cleaning of marine organisms from the surface of the float through a follow-up cleaning mechanism. When the float floats, it squeezes or pulls the telescopic rods, converting the force of vertical movement into compressive energy and transmitting it to the multi-stage telescopic rods, driving the cleaning plates to reciprocate and scrape away the organisms attached to the surface. Simultaneously, the spiral guide channels on the float surface create directional vortexes to assist in scouring, eliminating the need for manual cleaning or the use of chemical antifouling agents. This reduces maintenance costs, avoids marine environmental pollution, and ensures the float's motion response performance and wave energy capture efficiency.

[0020] 3. This invention achieves adaptive protection under harsh operating conditions through a storage mechanism and energy storage components. When the wind speed monitor detects strong winds or other severe conditions, the energy storage components recover compressed energy to retract the telescopic boom and multi-stage telescopic boom, allowing the cleaning plate to cover a wider area and eliminate blind spots. The storage mechanism retracts the telescopic boom into the storage slot, causing the float to retract to a position close to the base. This linkage mechanism effectively prevents the float from being damaged by violent shaking, improving the device's resistance to wind and waves and its service life in complex marine environments.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1 to 8 This invention provides a technical solution for a wave energy power generation device applied to marine buoys:

[0037] A wave energy generation device for marine buoys includes a buoy base component 1 and a buoy-mounted component 2 installed on top of the buoy base component 1. At least one set of float-type power generation mechanisms 3 are installed on the outer side of the buoy base component 1 to generate electricity using wave energy. The float-type power generation mechanism 3 includes a mounting portion 31 fixedly installed on the outer side of the buoy base component 1. A float 33 is rotatably connected inside the mounting portion 31 via a connecting shaft 34 and a connecting frame 32. The device also includes…

[0038] The follow-up cleaning mechanism 5 is correspondingly installed on a set of float-type power generation mechanisms 3 and works in conjunction with the set of float-type power generation mechanisms 3. It is used to clean the marine organisms attached to the set of float-type power generation mechanisms 3 by using the floating of the set of float-type power generation mechanisms 3. The follow-up cleaning mechanism 5 includes a telescopic rod 52 that is rotatably connected to the mounting part 31 and the connecting frame 32 through an ear plate to convert the force of the float 33 floating up and down with the waves into compressive energy. A multi-stage telescopic rod 55 is installed on the float 33 and communicates with the telescopic rod 52 through a conduit. A cleaning plate 56 is fixedly connected to the output end of the multi-stage telescopic rod 55. The multi-stage telescopic rod 55 receives the compressive energy converted by the telescopic rod 52 through the conduit to realize the reciprocating scraping of the cleaning plate 56.

[0039] During operation, the telescopic rod 52, the multi-stage telescopic rod 55, the conduit, and the horizontal flow tank 513 are in direct communication. When the float 33 rises with the waves, the connecting frame 32 compresses the telescopic rod 52, causing its internal gas to enter the multi-stage telescopic rod 55 through the conduit and horizontal flow tank 513. This pushes the multi-stage telescopic rod 55 to extend, thereby causing the cleaning plate 56 to scrape the outer surface of the float 33. When the float 33 sinks with the waves, the connecting frame 32 pulls the telescopic rod 52, creating a negative pressure inside. This draws the gas from the multi-stage telescopic rod 55 back into the telescopic rod 52 through the conduit and horizontal flow tank 513, causing the multi-stage telescopic rod 55 to retract. This causes the cleaning plate 56 to scrape the surface of the float 33 again. This process completes the gas circulation through the natural oscillation of the float 33, realizing the reciprocating scraping action of the cleaning plate 56.

[0040] As one embodiment of the present invention, such as Figure 2 , Figures 4 to 8As shown, it also includes a storage mechanism 4, installed inside the mounting part 31, and fixedly connected to the telescopic rod 52 via an output shaft. The buoy base component 1 also has an energy storage component 51 inside, which recovers and replenishes the compressed energy inside the telescopic rod 52 and the multi-stage telescopic rod 55, to adjust the length of the telescopic rod 52 and the multi-stage telescopic rod 55 and to adjust the angle of the float 33 by rotating the telescopic rod 52. A wind speed monitor is installed on the buoy component 2 to monitor the wind speed at the buoy's location in real time. The energy storage component 51 includes a pump body 511 with a controller, an energy storage tank 512, a shell, and a horizontal flow tank 513. One end of the pump body 511 is connected to the energy storage tank 512. The other end is connected to the horizontal flow tank 513. The horizontal flow tank 513 is connected to the telescopic rod 52 and the multi-stage telescopic rod 55 through a conduit. The energy storage tank 512 includes a fixed part fixedly connected to the shell and an expansion part disposed on the upper end of the fixed part and connected to the fixed part. The expansion part is an air bladder with rebound capability. The shell can be reasonably set according to actual use needs to ensure that the expansion part has enough space to expand. A connecting groove 54 is opened on the float 33. The multi-stage telescopic rod 55 is installed in the connecting groove 54. A groove is opened on the top of the cleaning plate 56. A storage groove 6 is opened inside the mounting part 31. The telescopic rod 52 is disposed inside the storage groove 6.

[0041] During operation, under normal conditions, the pump body 511 is in the closed state. At this time, the energy storage tank 512 and the horizontal flow tank 513 are not connected, so the gas in the horizontal flow tank 513 will not enter the energy storage tank 512. When the wind speed monitor on the buoy component 2 detects an abnormal operating condition (large wind and waves), by detecting changes in wind speed, it can prevent the buoy 33 from being retracted due to the waves generated when the ship passes by, thus affecting normal power generation. The wind speed monitor transmits the signal to the controller, and the controller controls the pump body 511 to start, and draws all the gas in the telescopic rod 52, the multi-stage telescopic rod 55, and the horizontal flow tank 513 into the energy storage tank 512 through the conduit. At this time, the telescopic rod 52 and the multi-stage telescopic rod 55 retract due to the sudden drop in internal air pressure, and the retraction force of the multi-stage telescopic rod 55 reaches its maximum. It drives the cleaning plate 56 to cover all the submerged positions of the float 33, making up for the blind spots caused by the insufficient stroke of the multi-stage telescopic rod 55 when the waves are small. After the wind and waves subside, the pump body 511 stops working, and the gas inside the energy storage tank 512 returns to the telescopic rod 52, the multi-stage telescopic rod 55 and the horizontal flow tank 513 through the pump body 511 to ensure normal operation.

[0042] Simultaneously, the storage mechanism 4 is activated, driving the telescopic rod 52 to rotate via the output shaft and retracting in coordination with the telescopic rod 52, completely retracting it into the storage slot 6 of the mounting part 31. This, in turn, causes the float 33 to retract to a position close to the buoy base 1, preventing damage to the float 33 due to violent shaking caused by excessive wind and waves. Since the upper surface of the float 33 is not submerged in seawater, it is not easy for marine organisms to adhere to it, thus requiring no additional cleaning.

[0043] Among them, the wind speed monitor uses the EL-15 wind speed sensor, the controller uses the STM32 series embedded controller, and the pump body 511 is the FML-200 miniature electromagnetic pneumatic pump.

[0044] As one embodiment of the present invention, such as Figures 3 to 5 As shown, the mounting part 31 has a through groove that communicates with the inside of the buoy base 1. The buoy base 1 is equipped with a power generation component 36. One end of the connecting shaft 34 is inserted through the through groove. The connecting shaft 34 is connected to the rotor on the power generation component 36 via a belt pair 35. The buoy base 1 is also equipped with a collection component 37, which includes an inverter and a battery. A wire is provided between the power generation component 36 and the inverter, and the inverter and the battery are electrically connected.

[0045] During operation, the float 33 rotates around the connecting shaft 34 under the thrust of the waves. This rotation is caused by the connecting frame 32, which in turn drives the connecting shaft 34 to rotate. The belt pair 35 at the other end of the connecting shaft 34 transmits the rotational motion to the rotor of the power generation component 36, driving the power generation component 36 to cut magnetic field lines and generate electrical energy. The electrical energy is transmitted through wires to the inverter of the collecting component 37, where it is converted into stable DC power and stored in the battery. This process realizes the conversion and storage of wave energy into electrical energy. The stored electrical energy is used to power the electronic components installed on the buoy component 2.

[0046] As one embodiment of the present invention, the surface of the float 33 is etched with spiral guide grooves (not shown in the figure), and when the float 33 moves, it guides the water flow to form a directional vortex to wash away the organisms attached to the surface.

[0047] During operation, the float 33 reciprocates under the action of waves, and the spiral guide channels on its surface guide the water flow along the channels, forming a high-speed directional vortex. When the vortex flows over the surface of the float 33, it generates a continuous scouring force on the attached marine organisms, peeling off shallow-layer attached organisms and assisting the follow-up cleaning mechanism 5 to improve the antifouling effect.

[0048] As one embodiment of the present invention, such as Figure 6 As shown, a protective sleeve 53 is fixedly connected to the outside of the float 33, and the protective sleeve 53 covers the connection between the guide tube and the multi-stage telescopic rod 55.

[0049] During operation, the protective sleeve 53 isolates seawater, silt, and marine life from direct contact with the connection points of the conduit and multi-stage telescopic rod 55, preventing the interfaces from being corroded or blocked.

[0050] Working principle:

[0051] During the wave energy generation process, the float 33 rotates up and down with the waves, and drives the connecting shaft 34 to rotate through the connecting frame 32. The connecting shaft 34 transmits the rotational motion to the power generation component 36 in the buoy base component 1 through the belt pair 35, which drives it to cut magnetic field lines to generate electrical energy. The electrical energy is converted into stable DC power by the inverter of the collection component 37 and then stored in the battery to power the electronic equipment on the buoy.

[0052] The follow-up cleaning mechanism converts the force of the up-and-down floating into compressed gas pressure by squeezing or pulling the telescopic rod 52 through the connecting frame 32. The compressed energy is transmitted to the multi-stage telescopic rod 55 on the float 33 through the conduit, driving it to extend and retract, which in turn drives the cleaning plate 56 to scrape off the marine organisms attached to the surface of the float 33. At the same time, the spiral guide groove on the surface of the float 33 forms a directional vortex during the movement, which helps to flush the surface organisms and enhances the cleaning effect.

[0053] Adaptive adjustment under harsh working conditions: When the wind speed monitor on component 2 of the buoy detects severe working conditions such as strong winds, the energy storage component 51 recovers the compressed energy in the telescopic rod 52 and the multi-stage telescopic rod 55, causing them to retract. The cleaning plate 56 covers more areas of the float 33 to eliminate blind spots in cleaning. At the same time, the storage mechanism 4 puts the telescopic rod 52 into the storage slot 6 of the installation part 31, driving the float 33 to retract to a position close to the base to avoid damage from violent shaking.

[0054] The auxiliary protection structure, the protective sleeve 53 on the outside of the float 33, covers the connection between the guide tube and the multi-stage telescopic rod 55 to prevent seawater and biological corrosion or blockage of the interface, and ensure stable transmission of compressed energy.

[0055] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
