[0026] Embodiment 1 See also Figure 1 , Figure 2 and Figure 3 A marine comprehensive development and utilization device includes a photovoltaic platform 1, a wave power generation array 2 and support piles 3.

[0027] The photovoltaic platform 1 of this embodiment is located above the sea surface, using the open sea surface to receive sufficient sunlight, and converts solar energy into electrical energy through the photovoltaic effect, which is not limited by terrain and ground conditions, greatly improving the utilization efficiency of solar energy. The wave power generation array 2 is located directly below the photovoltaic platform 1, and converts the kinetic energy of ocean waves into electrical energy. Wave energy is a clean and renewable energy source with the advantages of high energy density and wide distribution. By converting wave energy into electrical energy, the energy potential of the ocean is further tapped. The support pile 3, as the supporting structure of the entire device, not only ensures the stable operation of the photovoltaic platform 1 and the wave power generation array 2, but also improves the wind and wave resistance of the device through reasonable layout and design. Combining photovoltaic power generation with wave power generation realizes the comprehensive development of marine energy, which not only improves the energy utilization efficiency, but also reduces the dependence on a single energy source, and enhances the stability and reliability of energy supply. The wave power generation array 2 and the support pile 3 are connected by sliding, allowing the wave power generation array 2 to move to a certain extent under the action of waves, thereby reducing the impact of waves on the device and improving the durability and safety of the device.

Photovoltaic power generation and wave power generation are both clean energy, do not produce harmful gases and waste, and do not pollute the environment. Through the large-scale application of this marine comprehensive development and utilization device, it is possible to reduce dependence on traditional energy and reduce the emission of greenhouse gases such as carbon dioxide.

[0028] The photovoltaic platform 1 also includes a photovoltaic component 11 and a photovoltaic bracket 12. The photovoltaic component 11 is installed on one end of the photovoltaic bracket 12. The other end of the photovoltaic bracket 12 is connected to one end of a steering machine 13. The other end of the steering machine 13 is installed on the support pile 3.

[0029] The photovoltaic assembly 11 of this embodiment is installed on one end of the photovoltaic bracket 12, which can ensure that the photovoltaic assembly 11 can receive sunlight to the maximum extent, thereby improving the efficiency of photovoltaic power generation. By adjusting the angle and height of the photovoltaic bracket 12, the layout of the photovoltaic assembly 11 can be further optimized to adapt to the lighting conditions of different seasons and time periods. As the supporting structure of the photovoltaic assembly 11, the photovoltaic bracket 12 not only ensures the stability and safety of the photovoltaic assembly 11, but also allows the photovoltaic assembly 11 to be displaced or adjusted to a certain extent when necessary. This flexibility helps to reduce the impact of natural factors such as wind pressure and snow pressure on the photovoltaic assembly 11, and improve the durability and reliability of the photovoltaic platform. The steering machine 13 is connected between the photovoltaic bracket 12 and the support pile 3, and the angle of the photovoltaic bracket 12 and the photovoltaic assembly 11 can be adjusted, so that the photovoltaic platform 1 can be adaptively adjusted according to the position and light intensity of the sun, ensuring that the photovoltaic assembly 11 can always receive the maximum amount of sunlight, thereby improving the efficiency of photovoltaic power generation. At the same time, the steering machine 13 can also make necessary adjustments according to weather conditions such as strong winds and heavy rains to reduce the damage to the photovoltaic platform caused by natural factors.

[0030] See also Figure 4 The steering machine 13 includes an annular vertical support 131, a steering mechanism and a fixture 135. The upper part of the annular vertical support 131 is connected to the other end of the photovoltaic bracket 12, and the lower part of the annular vertical support 131 is connected to the steering mechanism. The steering mechanism is installed on the upper part of the fixture 135, and the lower part of the fixture 135 is installed on the support pile 3; The steering mechanism includes a rotating structure and a limiting structure. The rotating structure is installed on the limiting structure. The rotating structure is connected to the lower part of the annular vertical support 131 , and the limiting structure is installed on the upper part of the fixer 135 .

[0031] The rotating structure includes a roller 132 and a slide rail 133 , the limiting structure includes a slide seat 134 , and the roller 132 is slidably connected to the slide rail 133 .

[0032] The annular vertical support 131 of this embodiment serves as a connecting piece between the photovoltaic bracket 12 and the steering mechanism, ensuring the stability and rigidity of the photovoltaic bracket. At the same time, its vertical design helps to reduce the impact of wind resistance and waves on the photovoltaic platform, and improve the overall stability of the photovoltaic platform; the rotating structure is composed of rollers 132 and slide rails 133. This design allows the photovoltaic bracket 12 and the photovoltaic assembly 11 to rotate or slide smoothly on the slide rails 133, so that the photovoltaic platform 1 can be adaptively adjusted according to the position and light intensity of the sun, ensuring that the photovoltaic assembly 11 can always receive the maximum amount of sunlight, thereby improving the efficiency of photovoltaic power generation. The limiting structure is composed of a slide seat 134, which is installed on the upper part of the fixture 135, providing stable support and limiting for the rotating structure, ensuring the accuracy and stability of the photovoltaic bracket 12 during the rotation process, and avoiding excessive shaking or offset; the sliding connection between the roller 132 and the slide rail 133 has the characteristics of low friction and high wear resistance, which not only reduces the energy loss during the rotation process, but also improves the adjustment accuracy and response speed of the photovoltaic platform. The modular design of the steering gear makes it easy to disassemble and replace various components such as rollers 132, slide rails 133, and slide seats 134. The various components of the steering gear 13 are made of high-quality materials with high strength, high wear resistance, and corrosion resistance, ensuring the durability and reliability of the steering gear 13 and extending the service life of the photovoltaic platform 1; the structural design of the steering gear 13 can reduce problems such as stress concentration and fatigue damage, improve the overall strength and stability of the photovoltaic platform 1, and help ensure the safe operation of the photovoltaic platform 1 under severe weather conditions.

[0033] The wave power generation array 2 includes a wave power generation float 21 , a slider 4 and a connector 5 . The slider 4 is installed on the support pile 3 , and the wave power generation float 21 is connected to the slider 4 via the connector 5 .

[0034] The wave power generation float 21 of this embodiment is a component that directly interacts with waves, and can absorb the kinetic energy of waves and convert it into mechanical energy or electrical energy. The slider 4 and the connector 5 allow the wave power generation float 21 to slide smoothly under the action of waves, which can reduce the impact and resistance of waves on the float, thereby improving the conversion efficiency of wave energy. The slider 4, as a connector between the wave power generation float 21 and the support pile 3, plays a key supporting and stabilizing role. The slider 4 and the connector 5 allow the wave power generation float 21 to slide within a certain range, which can reduce the friction and wear between the float and the support structure, reduce the risk of fatigue damage, and thus extend the service life of the wave power generation array 21. The modular design of each component of the wave power generation array 21 facilitates installation and maintenance. By disassembling and replacing faulty components, the normal operation of the wave power generation array can be quickly restored. The slider 4 and the connector 5 allow the wave power generation float 21 to be easily installed on the support pile 3 without the need for complex fixing and connection structures. The design reduces installation costs and improves installation efficiency. The wave power generation array 21 has a certain flexibility and can be adjusted and optimized according to the wave conditions and environmental characteristics of different sea areas. For example, by adjusting the shape and size of the wave power generation float 21, it can adapt to wave conditions of different wave heights and wave frequencies. The wave power generation array 21 can be applied to different sea environments such as deep sea, shallow sea, near sea and offshore.

[0035] See also Figure 5 The wave power generation float 21 includes a closed cavity and a power generation device. The power generation device includes a power generation module 211, a transmission mechanism, a reversing rod 216, a support rod 217 and a transmission rod 6. The power generation module 211 is connected to one end of the reversing rod 216 through the transmission mechanism, the other end of the reversing rod 216 is connected to one end of the support rod 217, the other end of the support rod 217 is connected to the transmission rod 6, and the power generation module 211 is arranged in the closed cavity.

[0036] The power generation module 211 of this embodiment is connected to the reversing rod 216 through a transmission mechanism, which can efficiently convert the kinetic energy of the waves into electrical energy. The transmission mechanism can convert the up and down floating or swinging of the float into a unidirectional rotational motion, thereby driving the power generation module to generate electricity. The reversing rod 216 and the support rod 217 ensure that the power generation module 211 can continuously and stably generate electricity under the action of waves. The reversing rod can change the transmission direction, so that the power generation module 211 can always maintain unidirectional rotation during the reciprocating motion of the waves, thereby improving the power generation efficiency. The enclosed cavity not only protects the power generation device from seawater erosion, but also provides buoyancy for the entire wave power generation float 21. At the same time, the enclosed cavity can also reduce the energy loss in the energy conversion process and improve the power generation efficiency. The stable connection between the support rod 217 and the transmission rod 6 ensures the stability of the power generation module 211 during the power generation process, and can prevent the power generation module 211 from shaking or deflecting under the action of waves, thereby ensuring the stability and continuity of power generation.

[0037] A plurality of wave power generation floats 21 are provided, and the plurality of wave power generation floats 21 are connected via a transmission rod 6 .

[0038] In this embodiment, multiple wave power generation floats 21 are connected by a transmission rod 6 to form a series power generation system. Under the action of waves, each float absorbs the kinetic energy of the waves and converts it into electrical energy. Since multiple floats work at the same time, the power generation efficiency of the entire system will be significantly improved. The transmission rod 6 not only plays a connecting role, but also can accumulate and transfer energy to a certain extent. When a wave pushes a float, the float will transfer part of the energy to the adjacent float through the transmission rod 6. In this way, even if a float cannot fully generate electricity due to poor wave conditions, other floats can also be supplemented by the energy transmitted by the transmission rod, thereby improving the stability and power generation efficiency of the entire system. Multiple wave power generation floats 21 are connected by a transmission rod 6, which can disperse the risks caused by failure or damage of a single float. Even if a float has problems, other floats can still continue to work to ensure the stable operation of the entire system. In harsh marine environments, a single wave power generation float may be impacted by larger wind and waves, and after multiple floats are connected by a transmission rod, a more stable structure can be formed to improve the wind and wave resistance of the entire system. The design that multiple wave power generation floats 21 are connected by a transmission rod 6 facilitates installation and maintenance work. The floats can be installed and debugged one by one, and can also be maintained and replaced one by one, which not only improves the installation efficiency but also reduces the installation cost. Since the floats can be installed one by one, there is no need for large-scale construction equipment and manpower investment, thereby saving installation costs. By setting up multiple wave power generation floats 21 and connecting them, the wave resources in the ocean can be more fully utilized. In sea areas with good wave conditions, the number of floats can be increased to improve power generation efficiency; in sea areas with poor wave conditions, the number of floats can be appropriately reduced to reduce costs.

[0039] The transmission mechanism includes a transmission shaft 212, a damper 213, a transmission piston 214 and a guide rod 215. The power generation module 211 is connected to the guide rod 215 through the transmission shaft 212. The transmission piston 214 is installed on the guide rod 215. The damper 213 is arranged between the transmission piston 214 and the guide rod 215. The transmission piston 214 is connected to one end of the reversing rod 216.

[0040] The transmission shaft 212 of this embodiment, as a key component connecting the power generation module 211 and the guide rod 215, can effectively convert wave energy into mechanical energy and transmit it to the power generation module, ensuring efficient conversion and stable transmission of energy. The installation design of the transmission piston 214 on the guide rod 215 enables the piston to reciprocate under the impetus of the waves, which can convert the kinetic energy of the waves into the mechanical energy of the piston, and then drive the power generation module to generate electricity. The guide rod 215 plays the role of guiding and supporting the transmission piston, ensuring the stability and accuracy of the movement. The setting of the damper 213 between the transmission piston 214 and the guide rod 215 plays an important role in shock absorption and buffering. Under the impact of waves, the transmission piston 214 will produce large vibrations and impact forces. The damper 213 can absorb these vibrations and impact forces, reduce the damage to the entire transmission mechanism, and thus improve the stability and durability of the system. The damper 213 can not only reduce the damage to the transmission mechanism caused by vibration and impact force, but also reduce the loss of energy during the transmission process. The connection design between the reversing rod 216 and the transmission piston 214 enables the reciprocating motion of the piston to be converted into the unidirectional rotational motion of the reversing rod 216, thereby optimizing the energy conversion process and enabling the power generation module 211 to receive and convert energy more efficiently. At the same time, the unidirectional rotational motion of the reversing rod 216 is also more stable and smooth, reducing fluctuations and instability factors in the power generation process.

[0041] The photovoltaic platform 1 is inclined at an angle to the horizontal direction.

[0042] The tilt angle of this embodiment can make the photovoltaic panel face the sun more directly, especially in different seasons and time periods, the position of the sun will change, ensuring that the photovoltaic panel can receive solar radiation to the greatest extent for most of the time, thereby improving the utilization rate of solar energy. Horizontally installed photovoltaic panels may lose part of the solar energy due to ground reflection and sky scattering, while tilted installation can reduce the impact of these reflections and scattering, so that the photovoltaic panel can receive solar energy more efficiently. The design of the tilt angle helps the photovoltaic panel to maintain a better working state when receiving solar energy. Due to the existence of the tilt angle, the photovoltaic panel can more effectively convert solar energy into electrical energy, thereby improving the power generation efficiency. The tilted photovoltaic panel can better dissipate heat and reduce the decrease in power generation efficiency caused by high temperature. Especially in the hot summer, the design of the tilt angle can significantly reduce the temperature of the photovoltaic panel, thereby improving its power generation performance. The design of the tilt angle enables the photovoltaic panel to better withstand the influence of natural forces such as wind pressure and snow pressure, and can ensure that the photovoltaic panel can still maintain a stable working state under severe weather conditions. The tilted photovoltaic panel can more easily discharge debris such as snow and dust, thereby keeping the photovoltaic panel clean and working efficiently, extending the service life of the photovoltaic panel and improving the power generation efficiency. According to the characteristics of different geographical locations and climatic conditions, the inclination angle of the photovoltaic platform can be flexibly adjusted to adapt to different solar radiation intensity and wind direction and speed conditions. , ensuring that the photovoltaic panels can maintain the best power generation performance in different environments.

[0043] Embodiment 2 A method for comprehensive development and utilization of the ocean, using the device for comprehensive development and utilization of the ocean described in Example 1, comprises the following steps: The photovoltaic platform 1 is installed above the sea surface through the support piles 3, and uses the solar energy to generate electricity by following the sunlight through the steering machine 13. The wave power generation array 2 floats on the sea surface through the support piles 3, and the wave power generation array 2 follows the ups and downs of the waves to capture the wave energy and convert it into electrical energy.

[0044] The photovoltaic platform 1 of this embodiment is installed above the sea surface through supporting piles, and uses the steering machine 13 to follow the sunlight to generate electricity, which can maximize the use of solar energy resources, because solar energy is an inexhaustible and renewable energy with the advantages of cleanliness, environmental protection, and sustainability. The wave power generation array 2 floats on the sea surface through the supporting piles 3, following the ups and downs of the waves to capture wave energy and convert it into electrical energy. Wave energy is also a renewable energy source in the ocean, with high energy density, wide distribution, and easy direct use. Solar energy and wave energy have certain complementarity in time distribution. For example, when the sun is sufficient during the day, the photovoltaic platform 1 can generate electricity; at night or on cloudy days, the wave power generation array 2 can continue to supply electricity. This complementarity enables the entire system to provide a stable energy supply in different time periods. Due to the relatively complex marine environment, traditional energy supply methods may be affected by natural disasters such as typhoons and tsunamis. The comprehensive development and utilization method of the ocean provided in this embodiment can better resist these disasters, because the photovoltaic platform 1 and the wave power generation array 2 both have certain floating and adaptability, which can reduce the impact of disasters on energy supply to a certain extent.

[0045] Embodiment 3 This embodiment provides a marine comprehensive development and utilization device whose main structure is composed of support piles 3, wave power generation arrays 2, sliders 4, photovoltaic platforms 1, photovoltaic brackets 12, steering gears 13, connectors 5, transmission rods 6, etc.

[0046] A marine comprehensive development and utilization device in this embodiment is a type that integrates a fixed structure and a floating structure, wherein a photovoltaic platform 1 is supported by a pile foundation and is suitable for sea areas with a water depth of less than 15 meters. In this embodiment, a photovoltaic platform 1 includes four photovoltaic modules 11 and four supporting piles 3, wherein one supporting pile 3 supports one photovoltaic module 11, and the four supporting piles 3 are arranged in a rectangular shape. The space formed by the four supporting piles 3 below the photovoltaic platform 1 is used to develop a wave energy power generation array 2, and the array as a whole floats on the sea surface. The wave energy power generation device adopts a modular design, wherein the peripheral modules are connected to the pile foundation through a slider 4 and a flexible connector 5, and the inner modules are connected through a transmission rod 6, so that the mechanical energy generated by the relative movement between the modules is converted into electrical energy.

[0047] The fixed photovoltaic platform 1 is inclined at a certain angle to the horizontal direction and is installed on the pile foundation, i.e., the support pile 3, through the photovoltaic bracket 12 and the steering gear 13. The angle selection is determined according to the local latitude. The photovoltaic bracket 12 is connected to the photovoltaic platform 1 using a triangular structure composed of adjacent diagonal braces, which improves the structural stability.

[0048] The photovoltaic bracket 12 is connected to the steering machine 13 installed on the pile foundation through the annular vertical support structure 131. The steering machine 13 can drive the entire photovoltaic platform 1 to rotate around the pile foundation to adjust the azimuth and improve the power generation performance of the photovoltaic module 11. The steering machine 13 is composed of rollers 132, slide rails 133, slide seats 134, and fixtures 135. The steering machine 13 is clamped and installed with the pile foundation through the fixture 135. The rotation control is mainly completed by the sliding of the roller 132 on the slide rail 133. The slide seat 134 controls the movement of the roller 132. When the photovoltaic platform 1 rotates to the specified position, the slide seat 134 limits the roller 132 to ensure the structural stability of the photovoltaic platform 1.

[0049] The space enclosed by the pile foundation is used to place the wave power generation array 2, which is composed of hexagonal power generation floats, namely wave power generation floats 21. The outer floats of the array are connected to the pile foundation through flexible connectors and sliders 4. The slider 4 only limits the lateral movement of the power generation array, and allows the power generation module 211 to move in the vertical direction to generate electricity. In addition to the connection function, the existence of the slider 4 also allows the wave power generation array 2 to adapt to changes in water depth during the periodic tidal changes of high tide and low tide.

[0050] The floats in the wave energy array, i.e., the wave power generation array 2, are connected by the transmission rod 6. The float is a hexagonal structure, and the interior is composed of a closed cavity and a power generation device. The closed cavity provides buoyancy for the float, and the power generation device mainly includes a transmission rod 6, a support rod 217, a reversing rod 216, a transmission device, a power generation module 211 and other structures. The float floats up and down under the action of waves. The support rod 217 and the transmission rod 6 are hinged by a hinge joint 218, the support rod 217 and the reversing rod 216 are hinged, and the reversing rod 216 and the transmission piston 214 are hinged. The relative movement between the floats drives the support rod 217 and the reversing rod 216 through the transmission rod 6 to convert the reciprocating motion of the transmission piston 214 along the guide rod 215. The damper 213 helps to improve the motion stability of the transmission piston 214 and enhance the motion restoring force. The lateral motion of the transmission piston 214 is converted into the rotation of the rotor inside the power generation module 211 through the transmission shaft 212, thereby generating electrical energy.

[0051] This embodiment can be expanded on a large scale. Due to its slender characteristics, the pile foundation has little effect on wave energy attenuation, allowing the wave energy power generation array to capture as much wave energy as possible. In addition, the fixing method of the slider 4 can reduce the excessive movement of the wave power generation array 2 caused by severe sea conditions and reduce the risk of failure.
