Description
Technical Field
[0001] The invention belongs to the technical field of water photovoltaics and relates to a floating photovoltaic platform capable of actively eliminating waves. Background Art
[0002] With the transformation of the global energy structure and the enhancement of environmental protection awareness, the photovoltaic power generation industry is facing unprecedented development opportunities. However, the tight land resources and the impact of the surrounding environment have greatly restricted the layout of road photovoltaics. Therefore, floating photovoltaic technology came into being and gradually became the third pillar of the future photovoltaic market.
[0003] Floating photovoltaic technology is an innovative energy solution. Its core concept is to install photovoltaic panels on specially designed floating platforms that can stably float on the water surface, thereby effectively utilizing vast water resources for photovoltaic power generation. This technology has received widespread attention and favor from the industry because it can capture and utilize abundant solar energy resources without occupying land space.
[0004] However, although floating photovoltaic technology has shown great application potential, it still faces severe challenges in actual application, especially in the marine environment. The marine environment is complex and changeable, and the wave conditions are particularly harsh, which places extremely high demands on the stability of the floating platform. At present, many existing floating platforms perform poorly in wave resistance, and it is difficult to maintain the stability and efficient operation of photovoltaic panels under continuous wave impact. Therefore, how to improve the wave resistance of the floating platform and ensure the stable operation of the photovoltaic system in various extreme marine environments has become a key issue that needs to be urgently solved in the current development of floating photovoltaic technology. Summary of the invention
[0005] The purpose of the present invention is to solve the technical problem in the prior art that the wave conditions in the offshore environment are severe and the wave resistance effect of the floating photovoltaic platform is poor, and to provide a floating photovoltaic platform that can actively break the waves.
[0006] In order to achieve the above object, the present invention adopts the following technical solutions: The present invention provides a floating photovoltaic platform capable of actively absorbing waves, comprising a platform float and an active wave absorbing device; The platform buoy includes a plurality of platform buoys, and the plurality of platform buoys are connected by a flexible connector; The active wave-breaking device is connected to the platform float; the active wave-breaking device includes an active wave-breaking board, an active wave-breaking cabin float and a propulsion rod; the active wave-breaking cabin float is provided with a radar wave-measuring sensor, and a control module is provided inside; one end of the propulsion rod is connected to the active wave-breaking cabin float, and the other end is connected to the active wave-breaking board; the control module controls the extension and retraction of the propulsion rod according to the data of the radar wave-measuring sensor, thereby driving the active wave-breaking board to move.
[0007] Furthermore, the active wave-breaking device is arranged on both sides of the platform buoy.
[0008] Furthermore, connecting rods are provided on both sides of the platform buoy, and the active wave-breaking device is fixedly connected to the connecting rods.
[0009] Furthermore, the active wave-breaking cabin float is connected to a negative pressure suction cylinder.
[0010] Furthermore, the active wave-breaking cabin float is connected to the negative pressure suction cylinder via a tension key.
[0011] Furthermore, the active wave-breaking device further comprises a wave-breaking porous structure, and the wave-breaking porous structure is arranged at the bottom of the active wave-breaking cabin float.
[0012] Furthermore, the wave-breaking porous structure is connected to the active wave-breaking plate via a supporting truss.
[0013] Further, the control module includes a servo motor, a servo driver and a communication module; The data of the radar wave measurement sensor is transmitted to the central servo controller through the communication module, and the central servo controller controls the servo motor to drive the servo driver to drive the propulsion rod to extend and retract.
[0014] Furthermore, each active wave-breaking plate corresponds to a central servo controller.
[0015] Furthermore, a connecting rod is provided on the side of the platform buoy outside the platform floating body, and the connecting rod is fixedly connected to the active wave-breaking device.
[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention discloses a floating photovoltaic platform capable of actively absorbing waves. The platform float adopts a method of connecting a plurality of platform buoys through flexible connectors. This design not only enhances the structural strength and stability of the entire platform, but also effectively absorbs and disperses the impact of waves on the platform, thereby improving the adaptability of the platform under different water conditions. The active wave absorbing device can monitor and analyze the wave conditions in the water area in real time by integrating components such as radar wave measuring sensors, control modules and propulsion rods. According to the sensor data, the control module intelligently adjusts the extension and contraction of the propulsion rod to drive the active wave absorbing board to move precisely, effectively offsetting or weakening the influence of waves on the photovoltaic panel, thereby ensuring that the photovoltaic panel is always under relatively stable lighting conditions, and significantly improving the power generation efficiency and stability. Through the built-in intelligent control system, remote monitoring and automatic adjustment of the active wave absorbing device are realized, greatly reducing the need for manual intervention. This not only improves the operation and maintenance efficiency, but also significantly reduces the operation and maintenance costs, making the entire photovoltaic platform more economical and efficient; the application of active wave absorbing technology not only reduces the impact and damage of waves on photovoltaic panels, prolongs the service life of photovoltaic equipment, but also improves the energy conversion efficiency of the entire system by reducing the energy loss caused by waves.
[0017] Furthermore, the introduction of the connecting rod provides an additional support structure for the platform float. Especially in the face of severe weather conditions such as strong winds and large waves, this design can effectively enhance the overall rigidity and stability of the platform, prevent the platform from deforming or tilting due to wave impact, thereby ensuring that the photovoltaic panels can continue to maintain a relatively stable working state and improve power generation efficiency and safety. By fixing the active wave-breaking device to the connecting rod, not only the installation process is simplified, but also the stability of the device is improved. This fixing method reduces the impact of the shaking of the floating platform caused by waves on the wave-breaking device, ensures that the radar wave measurement sensor can accurately capture wave information, and the control module can accurately control the extension and retraction of the propulsion rod, thereby more effectively realizing the active wave-breaking function.
[0018] Furthermore, the negative pressure suction cylinder uses the principle of negative pressure to firmly adhere to the bottom of the water through the suction generated internally, providing additional anchoring support for the platform. This design significantly enhances the stability of the platform in the water, especially in environments with turbulent water or large waves. It can effectively prevent the platform from being displaced or overturned due to external forces, ensuring that the photovoltaic panels can continuously and stably receive sunlight and improve power generation efficiency. The active wave-breaking cabin float is connected to the negative pressure suction cylinder through a tension key, which not only enhances the structural connection strength between the two, but also optimizes the overall force distribution of the platform. As a flexible connector, the tension key can absorb and disperse the impact force of waves on the platform to a certain extent, reduce stress concentration, and thus extend the service life of the platform.
[0019] Furthermore, the wave-absorbing porous structure, as a passive wave-absorbing means, can further absorb and disperse wave energy and reduce the direct impact of waves on the platform by being set at the bottom of the active wave-absorbing cabin float. Working in conjunction with the active wave-absorbing plate, a composite wave-absorbing mechanism is formed, which significantly improves the active wave-absorbing efficiency of the platform, allowing the platform to operate more stably when facing complex and changeable wave conditions. The wave-absorbing porous structure and the active wave-absorbing plate are connected by a supporting truss. This design not only enhances the structural connection strength between the two, but also improves the overall stability of the entire wave-absorbing device. As a rigid structure, the supporting truss can provide additional support force under the action of waves to prevent the wave-absorbing porous structure and the active wave-absorbing plate from being deformed or damaged due to wave impact.
[0020] Furthermore, the radar wave sensor can capture wave data in real time and quickly transmit it to the central servo controller through the communication module. Based on this data, the central servo controller can accurately calculate the movement mode and force required for each active wave-breaking board, thereby achieving accurate wave reduction. This precise control method ensures that the platform can respond quickly and effectively when facing complex and changeable wave conditions, thereby improving wave reduction efficiency. Each active wave-breaking board corresponds to a central servo controller. This independent control design enables each wave-breaking board to be independently adjusted according to the wave conditions at its location. This flexibility not only improves the overall stability of the platform, but also effectively avoids the tilt or displacement of the platform caused by excessive local waves, ensuring the stable operation of the photovoltaic panel. Through the synergy of the central servo controller and the communication module, the intelligent management of the active wave-breaking device is realized. The operation and maintenance personnel can understand the operation status and wave-breaking effect of the platform in real time through remote monitoring, so as to carry out targeted maintenance and adjustments. This intelligent management method not only reduces the operation and maintenance costs, but also improves the operation and maintenance efficiency. By precisely controlling the movement of the active wave-breaking panels, the impact and interference of waves on the platform is reduced, thereby improving the power generation efficiency and energy utilization of the photovoltaic panels. This not only helps to reduce energy costs, but also promotes the sustainable development of renewable energy and contributes to environmental protection and energy conservation and emission reduction.

[0030] The present invention is further described in detail below in conjunction with the accompanying drawings: See also Figure 1-6 The present invention discloses a floating photovoltaic platform capable of actively eliminating waves, comprising a platform float and an active wave elimination device; The platform buoy includes a plurality of platform buoys 6, which are connected by a flexible connector 4; the platform buoy is connected by modular platform buoys 6 through a flexible connector 4. A connecting rod is provided on the side of the platform buoy 6 outside the platform buoy, and the connecting rod is rigidly connected to the frame of the active wave absorbing device.
[0031] The active wave-breaking device is connected to the platform buoy; the active wave-breaking device includes an active wave-breaking plate 1, an active wave-breaking cabin buoy 2 and a propulsion rod 10; the active wave-breaking cabin buoy 2 is provided with a radar wave-measuring sensor 3, and a control module is provided inside; one end of the propulsion rod 10 is connected to the active wave-breaking cabin buoy 2, and the other end is connected to the active wave-breaking plate 1; the control module controls the extension and retraction of the propulsion rod 10 according to the data of the radar wave-measuring sensor 3, thereby driving the active wave-breaking plate 1 to move. The control module includes a servo motor 12, a servo driver 11 and a communication module 14; the data of the radar wave-measuring sensor 3 is transmitted to the servo motor 12 through the communication module 14, and the servo motor 12 controls the servo driver 11 to drive the propulsion rod 10 to extend and retract. The active wave-breaking device can be integrated in the periphery of the platform buoy, and connected to the external buoy of the platform buoy through a rigid connector. A radar wave sensor 3 is arranged on the wave-breaking cabin float 2, which can cover and measure the wave conditions of the sea surface at a certain distance. Before the irregular waves on the sea surface are transmitted to the platform float, the radar wave sensor 3 transmits the measured wave signal to the central servo controller 13 for spectrum analysis and directional spectrum analysis. Based on the active wave absorption theory, the central servo controller 13 calculates the corresponding motion mode of the active wave-breaking board 1, transmits the motion signal to the servo motor 12 through the communication module 14, and drives the active wave-breaking board 1 to move by controlling the servo driver 11 to drive the propulsion rod 10, thereby achieving the effect of active wave breaking. The buoyancy of the active wave-breaking device is provided by the active wave-breaking cabin float 2, which can ensure that the platform buoy 6 connected thereto will not generate a negative air gap. The active wave-breaking device also includes a wave-breaking porous structure 5, which is arranged at the bottom of the active wave-breaking cabin float 2. The wave-breaking porous structure 5 is connected to the active wave-breaking board 1 through a supporting truss 7. In particular, the wave-breaking porous structure 5 is installed behind the active wave-breaking board 1, which can reduce the waves generated by the active wave-breaking board 1 and transmitted toward the floating body, ensuring that the floating body will not be displaced too much due to the additional waves generated by the movement of the active wave-breaking board 1.
[0032] Specifically, each active wave-breaking board 1 is pushed by two propulsion rods 10, and the servo driver 11 in the active wave-breaking cabin buoy 2 drives the propulsion rod 10 to reciprocate, and the servo driver 11 is controlled and driven synchronously by the servo motor 12. The motion control of the propulsion rod 10 is completed by the central servo controller 13, and each active wave-breaking board 1 corresponds to a central servo controller 13, which performs wave-breaking action on the waves in the local area corresponding to the active wave-breaking board 1 according to the radar wave measurement signal.
[0033] The active wave absorbing device is arranged on both sides of the platform buoy, and in particular, the active wave absorbing device can be symmetrically arranged on both sides of the platform buoy. The active wave absorbing cabin buoy 2 is connected with a negative pressure suction cylinder 8; the active wave absorbing cabin buoy 2 is connected with the negative pressure suction cylinder 8 through a tension key 9.
[0034] The platform float of the present invention is connected by a plurality of modular platform floats 6 through a flexible connector 4. This design enables the platform float to adapt to the wave conditions in different waters and ensure the stable installation and operation of the photovoltaic panel. The side of the outer platform float 6 of the platform float is provided with connecting rods, which are rigidly connected to the frame of the active wave absorbing device, thereby enhancing the overall stability and wind and wave resistance of the platform. The radar wave sensor 3 is arranged on the active wave absorbing cabin float 2, which can cover and measure the sea surface wave conditions at a certain distance. When the irregular waves on the sea surface are transmitted to the platform float, the radar wave sensor 3 will capture the wave signal in real time; the captured wave signal is transmitted to the central servo controller 13 through the communication module 14. The central servo controller 13 performs spectrum analysis and directional spectrum analysis on the received wave signal to understand the characteristics of the wave; based on the active wave absorption theory, the central servo controller 13 calculates the corresponding motion mode of the active wave absorbing board 1. This calculation process takes into account factors such as the characteristics of the wave, the position of the platform float and the motion ability of the active wave absorbing board 1; the calculated motion signal is transmitted to the servo motor 12 again through the communication module 14. The servo motor 12 controls the servo driver 11 to drive the propulsion rod 10 to perform telescopic movement according to the received signal. Each active wave-breaking board 1 is pushed by two propulsion rods 10 and driven synchronously by the servo driver 11. The movement of the propulsion rod 10 is precisely controlled by the central servo controller 13 to ensure that the active wave-breaking board 1 can move in a predetermined manner, thereby effectively reducing the impact of waves on the platform buoy; the wave-breaking porous structure 5 is arranged at the bottom of the active wave-breaking cabin buoy 2 and is connected to the active wave-breaking board 1 through the support truss 7. This design can further absorb and disperse wave energy and reduce the direct impact of waves on the platform. In particular, when the active wave-breaking board 1 moves, the wave-breaking porous structure 5 can reduce additional waves transmitted to the floating body and ensure the stability of the platform buoy. The active wave-breaking device is arranged on both sides of the platform buoy and can be arranged symmetrically. This layout can maximize the effect of the active wave-breaking device and improve the platform's wind and wave resistance. The active wave-breaking cabin buoy 2 is also connected to a negative pressure suction cylinder 8, which is connected by a tension key 9. The negative pressure suction cylinder 8 can be firmly adsorbed to the bottom of the water by utilizing the negative pressure principle, providing additional anchoring support for the platform and further enhancing the stability of the platform.
[0035] In summary, the active wave-breaking device of the present invention, especially the coordinated use of the active wave-breaking plate and the propulsion rod, can realize active wave-breaking according to the wave data captured in real time by the radar wave-measuring sensor through the precise calculation and control of the control module. This dynamic response mechanism greatly improves the wave-breaking ability of the platform, effectively reduces the impact of waves on the platform, and ensures the stable operation of the photovoltaic equipment. The platform float adopts a modular design and is connected by flexible connectors, which enhances the overall structural strength and toughness of the platform. At the same time, the active wave-breaking device is arranged on both sides of the platform float and is fixedly connected by a connecting rod, which further enhances the wind and wave resistance of the platform. In addition, the addition of the wave-breaking porous structure and the supporting truss not only enhances the wave-breaking effect, but also improves the overall stability of the platform. Through the precise control of the active wave-breaking device, the shielding and interference of the waves on the photovoltaic panel are effectively reduced, thereby increasing the light-receiving area and light intensity of the photovoltaic panel, and then improving the utilization rate of photovoltaic energy. This is of great significance for promoting the utilization of renewable energy and energy conservation and emission reduction. The control module integrates a servo motor, a servo driver and a communication module to realize the intelligent management of the active wave-breaking device. Each active wave-breaking plate corresponds to a central servo controller. This independent control design enables operation and maintenance personnel to remotely monitor the operating status of the platform, discover and handle problems in a timely manner, reduce operation and maintenance costs, and improve operation and maintenance efficiency. The floating photovoltaic platform provided by the present invention can adapt to different water environments and wave conditions through modular design and adjustable active wave-breaking devices. Whether it is deep sea, offshore or inland lakes, it can achieve efficient and stable operation. This provides new ideas and solutions for the development and utilization of photovoltaic energy.
