Description

Technical Field

[0001] This invention relates to the field of marine buoy monitoring, and more specifically, to a marine buoy system that utilizes wave energy and photovoltaic power generation. Background Technology

[0002] Ocean buoys are an important means of observing hydrological and meteorological conditions in waters far from the shore. Generally speaking, ocean buoys are divided into moored buoys and drifting buoys. Moored buoys can observe meteorological elements such as wind, temperature, humidity, pressure, sunshine and precipitation at a fixed position, as well as hydrological and meteorological elements such as seawater illumination, noise, current velocity, water temperature, salinity and waves. They are an important means of observing hydrological and meteorological conditions in waters far from the shore. Moored buoys can limit the displacement range of the buoy and improve its survivability.

[0003] In existing technologies, most marine environmental measurement buoys, both domestically and internationally, are powered by solar energy. As measurement tasks increase, the energy consumption of marine buoys also rises. Due to the limited size of marine buoys, it is impossible to increase the efficiency of solar power generation by installing large-area solar panels on land. Furthermore, adding solar panels may increase the wind resistance area of ​​the marine buoy, which is detrimental to its survivability, stability, and deployment difficulty. Besides solar power, wave energy power has also been proposed, but the existing marine buoy air intake chamber design is unreasonable, with insufficient space and inadequate power generation, failing to achieve ideal efficiency.

[0004] How to extend the lifespan of buoys by using clean marine energy is a problem that urgently needs to be solved in this field. Summary of the Invention

[0005] The present invention aims to overcome at least one of the defects (deficiencies) of the prior art and provide a wave energy and photovoltaic power generation marine buoy system to solve the problems of short service life and complex marine maintenance of marine buoys when collecting and monitoring meteorological data.

[0006] The technical solution adopted by this invention is a wave energy and photovoltaic power generation marine buoy system, including a meteorological monitoring device, a buoy body, and a mooring device. The meteorological monitoring device is located above the buoy body and is used to monitor marine meteorological data. The buoy body includes a float suspended on the sea surface. The mooring device is located below the buoy body and is used to anchor to the seabed. The system also includes: a counterweight seat located below the float to control the center of gravity of the buoy body to be submerged in seawater; the counterweight seat is fixedly connected to the mooring device; a power generation module including a photovoltaic power generation module and a wave power generation module; the photovoltaic power generation module including multiple vertically distributed photovoltaic panels mounted on a mast frame connected between the meteorological monitoring device and the buoy body for photovoltaic power generation; the wave power generation module including a wave generator set and at least two pressure wells vertically penetrating the buoy body; the wave generator set being located at the top of the pressure wells; and a power storage module for storing the electricity generated by the power generation module and discharging it to the meteorological monitoring device.

[0007] It is beneficial to provide support for the buoy body's suspension state through the counterweight seat; it is beneficial to provide power to the meteorological monitoring device through the power generation module; it is beneficial to provide support for the meteorological monitoring device through the mast frame, and at the same time provide support for the photovoltaic panel; it is beneficial to realize the conversion of wave energy into kinetic energy through the pressure well and the wave generator set; it is beneficial to store the electrical energy generated in the power generation module through the energy storage module and stably discharge it to the meteorological monitoring device.

[0008] Furthermore, the float is cylindrical and is a lightweight buoyancy device. The mast is connected to the center of the upper surface of the float, and the center of gravity of the mast, the meteorological monitoring device, and the float are located on the same vertical line.

[0009] It is beneficial to achieve the buoyancy requirement of the buoy through the float; it is beneficial to control the meteorological monitoring device to be stably placed on the buoy body through the connection position of the mast frame, reducing the influence of the meteorological monitoring device on the buoy body floating with the waves; it is beneficial to limit the displacement range of the meteorological monitoring device by the consistency of the center of gravity of the mast frame, the meteorological monitoring device and the float, thereby improving the accuracy of data acquisition.

[0010] Furthermore, the counterweight base includes a straight cylindrical portion and a horn-shaped portion. The straight cylindrical portion is connected to the bottom of the float, and the horn-shaped portion is connected to the mooring device. The horn-shaped portion is a cavity, and the circular area of ​​the lower bottom surface of the horn-shaped portion is larger than the circular area of ​​the upper bottom surface of the horn-shaped portion.

[0011] It is beneficial to lower the center of gravity of the buoy body by incorporating a weight inside the straight section, thereby increasing the stability of the buoy body; it is also beneficial to increase the contact surface between the waves and the buoy body by incorporating a flared section, thereby reducing the impact of waves and swells on the buoy body and reducing the traction force between the mooring device and the buoy body.

[0012] Furthermore, the pressure well includes a top and a bottom, the top including a top cap protruding from the upper surface of the float, and the lower surface including at least two holes matching the bottom.

[0013] The top cover protruding above the buoy facilitates maintenance and repair of the wave generator set by operators; it also facilitates the matching of the bottom of the pressure well with the hole on the lower surface of the counterweight base, enabling waves to do work on the pressure well in the vibration direction, thereby realizing the collection and conversion of wave energy.

[0014] Furthermore, the photovoltaic panel has a flat state and a folded state, the meteorological monitoring device is equipped with a photosensor, and the mast frame is equipped with a telescopic device. When the photosensor detects strong light, it controls the telescopic device to drive the photovoltaic panel to the flat state, and when the photosensor detects weak light, it controls the telescopic device to drive the photovoltaic panel to the folded state.

[0015] This allows for monitoring the intensity of sunlight over the sea using a photosensor, which in turn controls the state of the photovoltaic panels. This prevents the photovoltaic panels, which cannot be folded during heavy rain, from being affected by wind and rain, and also prevents the accumulation of bird droppings on the photovoltaic panels from affecting their efficiency, thereby extending the lifespan of the photovoltaic panels.

[0016] Furthermore, the power generation module also includes a wind power generation module, which includes a wind turbine unit protruding from the main body of the buoy for generating wind power.

[0017] This allows for an increase in the energy collection range of offshore power generation devices through the aforementioned wind power generation module, thereby improving the efficiency of marine clean energy collection.

[0018] Furthermore, the energy storage module includes a first energy storage power source, a second energy storage power source, and a third energy storage power source. The first energy storage power source is formed by connecting to the wave power generation module through a first rectifier; the second energy storage power source is formed by connecting to the wind power generation module through a second rectifier; and the third energy storage power source is formed by connecting to the photovoltaic power generation module through a photovoltaic controller.

[0019] This is beneficial for improving the output stability of the wave power generation module through the first rectifier, improving the output stability of the wind power generation module through the second rectifier, and improving the output stability of the photovoltaic power generation module through the photovoltaic controller, thereby extending the service life of the meteorological monitoring device.

[0020] Furthermore, the device includes multiple priority controllers. The meteorological monitoring device comprises a high-energy-consumption group, a low-energy-consumption group, and a basic-energy-consumption group. The priority controllers are used to prioritize the power of the first, second, and third power storage devices and connect them one by one to the high-energy-consumption group, the low-energy-consumption group, and the basic-energy-consumption group.

[0021] This allows for the sorting of the remaining power of the power storage system by multiple priority controllers, enabling a one-to-one match between the power storage system and the electrical load, thereby improving the efficiency of power utilization.

[0022] Furthermore, when the remaining power of any of the power storage sources is less than 5%, the priority ranking controller ranks the first two remaining power sources of the first, second, and third power storage sources and connects them one by one to the low-energy consumption group and the basic energy consumption group.

[0023] This allows for the reduction of pressure on the power storage unit by directly cutting off power supply to the high-energy-consuming group when the remaining power of any of the power storage units is less than 5%, thus ensuring the survival of the marine buoy. It also sends an alarm signal through the basic energy-consuming group to remind operators to charge and repair the buoy as soon as possible to restore its meteorological monitoring function.

[0024] Furthermore, the meteorological monitoring device includes a central control device, a signal transmission device, and a data detection device. After collecting data, the data detection device transmits the data to the central control device through the signal transmission device. The signal transmission device includes a BeiDou positioning device, a data transmission device, and a 5G antenna. The data detection device includes an anemometer and two cameras symmetrically arranged in front and behind. The basic energy consumption group includes the BeiDou positioning device, the low energy consumption group includes the data transmission device, the 5G antenna, and the central control device, and the high energy consumption group includes the anemometer and the cameras.

[0025] This system facilitates the provision of positioning for operators when the buoy system is without power, enabling operators to manually replenish power to buoy systems that cannot generate electricity and to perform maintenance. It also facilitates the emergency transmission of meteorological data monitored by the buoy system to the operator's central control unit when the buoy system is low on power, allowing for emergency storage of meteorological monitoring data. Furthermore, the high-energy-consumption group enables real-time collection, transmission, and storage of wind speed and direction data at sea, as well as images of the surrounding environment of the buoy system, allowing operators to remotely and in real-time monitor marine meteorological data and the buoy system's operational status.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: it is beneficial to provide support for the buoy body's suspension state through the counterweight seat, thereby enhancing the buoy's stability and facilitating maintenance by operators on the buoy; it is beneficial to generate electricity through the power generation module, enhance the conversion effect of wave energy to electrical energy through the dual pressure well and wave generator set, and enhance the conversion effect of solar energy to electrical energy through the vertically distributed photovoltaic panels; it is beneficial to store the electrical energy generated in the power generation module through the energy storage module and stably discharge it to the meteorological monitoring device, thereby extending the service life of the buoy for meteorological monitoring.

[0032] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the invention. To better illustrate the following embodiments, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions; it is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0033] Example 1

[0034] like Figure 1-3As shown, this embodiment provides a wave energy and photovoltaic power generation marine buoy system, including a meteorological monitoring device 100, a buoy body 200, and a mooring device 300. The meteorological monitoring device 100 is located above the buoy body 200 and is used to monitor marine meteorological data. The buoy body 200 includes a float 210 suspended on the sea surface. The mooring device 300 is located below the buoy body 200 and is used to anchor on the seabed. The system also includes a counterweight 220 located below the float 210 to control the center of gravity of the buoy body 200 to be submerged in seawater. The counterweight 220 is fixedly connected to the mooring device 300. 0; Power generation module, including a photovoltaic power generation module and a wave power generation module. The photovoltaic power generation module includes multiple vertically distributed photovoltaic panels mounted on a mast frame 400. The mast frame 400 is connected between the meteorological monitoring device 100 and the buoy body 200 for photovoltaic power generation. The wave power generation module includes a wave generator set and at least two pressure wells 500 that penetrate vertically through the buoy body 200. The wave generator set is located at the top of the pressure wells. Waves push the air chambers of the pressure wells to generate wave energy. Energy storage module, used to store the electricity of the power generation module and discharge it to the meteorological monitoring device 100.

[0035] In this embodiment, when deploying a buoy at sea, it is first anchored to the seabed using the mooring device 300. Then, the counterweight 220 is connected to the mooring device 300 via anchor cables, and the buoy body 200 is lifted and deployed to a predetermined floating range on the sea surface. The meteorological monitoring device 100 is mounted on the buoy body 200, which is suspended on the sea surface. Part of the float 210 is submerged in seawater, while another part is exposed to the air. The counterweight 220 is connected to the bottom of the float 210 and is completely submerged in seawater. The counterweight 220 is used to stabilize the center of gravity of the buoy body 200, preventing it from easily deviating from the predetermined floating range when there are waves.

[0036] In this embodiment, after the buoy is deployed, the meteorological data collection task begins. The energy storage module starts discharging to the meteorological monitoring device 100, and the electricity in the energy storage module comes from the charging of the power generation module. The photovoltaic power generation module in the power generation module converts solar energy from clear weather at sea into electrical energy through photovoltaic panels, and the wave power generation module converts the continuous wave energy of the ocean into electrical energy through wave generator sets and the pressure well 500. Through the mutual supplementation of the photovoltaic power generation module and the wave power generation module, the power supply of the power generation module is more sufficient.

[0037] The float 210 is cylindrical and is a lightweight buoyancy device. The mast frame 400 is connected to the center of the upper surface of the float 210. The center of gravity of the mast frame 400, the meteorological monitoring device 100 and the float 210 are located on the same vertical line.

[0038] In this embodiment, the mast frame 400 is a cubic frame, and the bottom surface connected to the center of the upper surface of the float 210 is quadrilateral. Multiple crossbars are provided on the side of the mast frame 400, and each crossbar can be used to install the photovoltaic panel. A circular bracket is also provided on the top surface of the mast frame 400. The meteorological monitoring device 100 is installed on the circular bracket. The maximum circular area of ​​the circular bracket is larger than the area of ​​the quadrilateral, so that the center of gravity of the meteorological monitoring device 100, the float 210 and the mast frame 400 can be located on the same vertical line, thereby maintaining the stability of the buoy body 200.

[0039] The counterweight seat 220 includes a straight cylindrical part and a horn-shaped part. The straight cylindrical part is connected to the bottom of the float 210, and the horn-shaped part is connected to the mooring device 300. The horn-shaped part is a cavity, and the circular area of ​​the lower bottom surface of the horn-shaped part is larger than the circular area of ​​the upper bottom surface of the horn-shaped part.

[0040] In this embodiment, the counterweight seat 220 consists of two parts. One part is a straight cylindrical section, which is used to fill with high-density counterweights such as lead blocks to stabilize the buoy body 200. The straight cylindrical section contacts the bottom of the float 210, and the straight cylindrical section and the bottom of the float 210 are completely matched without gaps. This helps to avoid the formation of a step on the contact surface between the float 210 and the counterweight seat 220, which would cause seawater to impact the step and reduce the service life of the counterweight seat 220. The other part is a flared section, which is hollow. The cavity includes four cylinders and a hanging ring, which is used to fill with high-density weights and connect the mooring device 300. The circular area of ​​the lower bottom surface of the flared section is larger than the circular area of ​​the upper bottom surface of the flared section, which helps to increase the volume of the counterweight seat 220 in the vertical direction, thereby making the center of gravity of the counterweight seat 220 downward and guiding the float 210 to float more stably on the sea surface.

[0041] The pressure well 500 includes a top and a bottom. The top includes a top cover that protrudes from the upper surface of the float 210, and the lower surface includes at least two holes that match the bottom.

[0042] In this embodiment, the pressure well 500 includes a gas collection chamber. Two symmetrically distributed gas collection chambers are provided through the buoy body 200. When the buoy body 200 is partially submerged in seawater, the bottom of the pressure well 500 is completely submerged in seawater. At this time, the vertical vibration of the waves drives the piston in the gas collection chamber to do work in the vertical direction, thereby collecting the mechanical energy of the waves. The top is provided with a top cover, so that when the wave generator set has a problem, the operator can repair it through the top cover.

[0043] The photovoltaic panel has a flat state and a folded state. The meteorological monitoring device 100 is equipped with a photosensitive sensor. The mast frame 400 is equipped with a telescopic device. When the photosensitive sensor detects strong light, it controls the telescopic device to drive the photovoltaic panel to the flat state. When the photosensitive sensor detects weak light, it controls the telescopic device to drive the photovoltaic panel to the folded state.

[0044] In this embodiment, the state of the photovoltaic panel can be adjusted to adapt to changes in marine solar energy, thereby extending the service life of the photovoltaic panel. The weather monitoring device 100 is equipped with a photosensor. When the photosensor detects that the light intensity of the day is between 100,000 Lux and 150,000 Lux, it determines that the weather at sea is sunny. At this time, the telescopic device extends the photovoltaic panel and makes it flat, perpendicular to the side of the mast frame 400, to increase the contact area between the photovoltaic panel and the sun and improve the solar energy collection efficiency. When the photosensor detects that the light intensity of the day is between 10,000 Lux and 30,000 Lux, it determines that the weather at sea is cloudy. At this time, the telescopic device retracts the photovoltaic panel and folds it, fitting it against the side of the mast frame 400 to prevent damage to the photovoltaic panel from sea waves or bird droppings, thus extending the service life of the photovoltaic panel.

[0045] The power generation module also includes a wind power generation module, which includes a wind turbine unit protruding from the buoy body 200 for generating wind power.

[0046] In this embodiment, to further improve the collection of clean marine energy, a wind power generation module is also provided in the power generation module to collect sea breeze and convert it into electrical energy. Since the buoy system is mostly deployed in offshore areas where sea breeze energy is abundant, while the efficiency of obtaining marine solar energy is not high, increasing the power generation efficiency of the power generation module and generating electricity from the continuous wind energy at sea can extend the service life of the buoy system.

[0047] The energy storage module includes a first energy storage power source, a second energy storage power source, and a third energy storage power source. The first energy storage power source is formed by connecting to the wave power generation module through a first rectifier; the second energy storage power source is formed by connecting to the wind power generation module through a second rectifier; and the third energy storage power source is formed by connecting to the photovoltaic power generation module through a photovoltaic controller.

[0048] In this embodiment, the energy storage module is a battery, which has a normal state and an emergency state. The normal state occurs when the battery's charge level is greater than 5%, and the emergency state occurs when the battery's charge level is less than or equal to 5%. In the normal state, the meteorological monitoring device 100 is powered by the battery; in the emergency state, the meteorological monitoring device 100 is powered directly by the power generation module after passing through the priority controller. The wave power generation module is connected to the first rectifier to ensure a continuous and stable output current after the wave generator set generates electricity; the wind power generation module is connected to the second rectifier to ensure a continuous and stable output current after the wind turbine generator set generates electricity; and the photovoltaic panel is connected to the photovoltaic controller to ensure a continuous and stable output current after the photovoltaic panel generates electricity.

[0049] The meteorological monitoring device 100 includes multiple priority controllers, comprising a high-energy-consumption group, a low-energy-consumption group, and a basic-energy-consumption group. The priority controllers are used to prioritize the power of the first, second, and third power storage devices and are connected to the high-energy-consumption group, the low-energy-consumption group, and the basic-energy-consumption group respectively.

[0050] In this embodiment, the meteorological monitoring device 100 is divided into three groups according to the amount of power consumption: a basic energy consumption group, a low energy consumption group, and a high energy consumption group. When the energy storage module, i.e., the battery, is in a normal state, the priority ranking controller does not work. When the energy storage module, i.e., the battery, is in an emergency state, the priority ranking controller starts working and ranks the photovoltaic power generation module, the wave power generation module, and the wind power generation module in the power generation module from high to low power generation. The power generation module with the highest power generation directly supplies power to the high energy consumption group, the power generation module with the medium power generation directly supplies power to the low energy consumption group, and the power generation module with the lowest power generation directly supplies power to the basic energy consumption group.

[0051] When the remaining power of any of the power storage sources is less than 5%, the priority ranking controller ranks the first two remaining power sources of the first, second, and third power storage sources and connects them one by one to the low-energy consumption group and the basic energy consumption group.

[0052] In this embodiment, if the remaining power of any of the power storage sources is less than 5%, the priority sorting controller sorts the power generation of the first, second, and third power storage sources in descending order, selects the two power storage sources with remaining power greater than 5%, and directly supplies power to the low-energy consumption group with the power storage source with the higher remaining power, and directly supplies power to the basic energy consumption group with the power storage source with the lower remaining power. At the same time, an alarm is issued to the remote monitoring operator to monitor and ensure the survival status of the buoy system in a timely manner.

[0053] The meteorological monitoring device 100 includes a central control device, a signal transmission device, and a data detection device. After collecting data, the data detection device transmits the data to the central control device through the signal transmission device. The signal transmission device includes a Beidou positioning device, a data transmission device, and a 5G antenna. The data detection device includes an anemometer and two cameras symmetrically arranged in front and behind. The basic energy consumption group includes the Beidou positioning device, the low energy consumption group includes the data transmission device, the 5G antenna, and the central control device, and the high energy consumption group includes the anemometer and the cameras.

[0054] In this embodiment, the basic energy consumption group includes the Beidou positioning device, which enables the buoy system to provide positioning for operators when it is without power, allowing operators to manually replenish power to the buoy system that cannot generate electricity and to perform maintenance on the buoy system; the low energy consumption group includes the data transmission device, the 5G antenna, and the central control device, which enables the buoy system to send emergency signals to operators when it is low on power to process the emergency storage of meteorological monitoring data, and to send real-time positioning to expedite the emergency charging and maintenance of the buoy system by operators; the high energy consumption group includes the anemometer and the camera, which enables the collection, transmission, and storage of marine meteorological data, and to send real-time positioning, allowing operators to remotely observe meteorological monitoring data and monitor the status of the buoy system.

[0055] Example 2

[0056] The difference between this embodiment and Embodiment 1 is that in this embodiment, the wave generator set and the wind turbine set rotate coaxially to superimpose kinetic energy. The wind turbine set protrudes from the buoy body 200. When the sea breeze blows, the wind turbine set rotates, and the wind turbine set and the wave generator set are connected to the same shaft to achieve the effect of superimposing the kinetic energy of the two sets. To adjust the rotational speed of the two sets, a first gear is connected to the wave generator set, and a second gear is connected to the wind turbine set, so that the rotational speeds of the wave generator set and the wind turbine set connected to the transmission gears are consistent.

[0057] The difference between this embodiment and Embodiment 1 is that, in order to guide the wind turbine and the wave generator to rotate in the same direction, a hood is also provided on the wind turbine. The hood guides the sea breeze to act directionally on the windward side of the wind turbine. Since the direction of sea breeze is variable and difficult to capture, a hood is provided on the wind turbine to enhance its wind breeze collection. The hood guides the sea breeze to act on the windward side of the wind turbine, ensuring that the rotation direction of the wind turbine is consistent with that of the wave generator, thus achieving the effect of the wind turbine providing auxiliary kinetic energy for the rotation of the wave generator.

[0058] This embodiment differs from Embodiment 1 in that the energy storage module in this embodiment only includes a first energy storage unit and a second energy storage unit. The first energy storage unit is formed by connecting the wave power generation module and the wind power generation module through a rectifier, and the second energy storage unit is formed by connecting the photovoltaic power generation module through a photovoltaic controller. In this embodiment, the energy storage module combines the power from the first and second energy storage units, presenting the total power of the energy storage unit. When the total power of the energy storage unit is higher than 5%, the priority ranking controller does not operate; when the remaining power of the total power storage unit is equal to or lower than 5%, the priority ranking controller starts operating and prioritizes the first and second energy storage units. The one with the larger remaining power supplies the basic energy consumption group, and an alarm is issued to remind operators to manually charge or repair the system in a timely manner to ensure the recyclability of the buoy system.
