Abstract
Description
Technical Field
[0001] This invention relates to the field of marine photovoltaic technology, and more specifically to an adaptive buffering floating block connection device for marine photovoltaic platforms. Background Technology
[0002] With the rapid development of the offshore photovoltaic industry, modular floating photovoltaic platforms have been widely used due to their advantages of flexible assembly and adaptability to different sea areas. The connecting devices between the floating modules, as core components ensuring the stability and safety of the platform structure, directly affect the operational reliability and service life of the photovoltaic platform. The marine environment is complex and changeable. The combined forces of wave-induced vertical swaying and lateral displacement of the floating body continuously act on the connecting devices. Simultaneously, harsh conditions such as high salt spray and seawater corrosion place stringent requirements on the sealing and protection performance of the connecting devices.
[0003] Existing technologies for connecting floating modules of offshore photovoltaic systems have several shortcomings: In terms of buffering and vibration reduction, traditional connection devices often employ single springs or rigid connection structures, which are ill-suited to complex and variable combined forces and cannot achieve dynamic damping control. Under normal sea conditions, they are prone to insufficient vibration reduction and severe swaying during operation. In extreme sea conditions, their insufficient resistance to deformation and load-bearing capacity can lead to damage or even failure of the connection structure. Regarding sealing and protection, existing sealing structures are mostly static designs, unable to adaptively adjust the sealing state according to the movement of the floating body. When the buffer components reciprocate, the fit between the seal and the moving components decreases, easily leading to seal failure. Furthermore, there is a lack of dynamic sealing reinforcement mechanisms linked to the movement state. In terms of safety warnings, existing technologies often lack specific seawater leakage warning systems, or the warning mechanisms are slow to respond and have low accuracy. When a seal fails and seawater seeps in, it cannot promptly alert personnel for maintenance, causing the buffer components to lose their elastic buffering capacity due to seawater erosion. This, in turn, creates safety hazards in the entire photovoltaic platform connection system, severely restricting the long-term stable operation of offshore photovoltaic platforms.

Under normal sea conditions, the secondary damping characteristics of the magnetohydrodynamic components enable flexible dissipation and adaptive adaptation to complex forces. Under extreme sea conditions, the magnetohydrodynamic damping is actively increased by precisely controlling the magnetohydrodynamic damping through the excitation coil, significantly enhancing the deformation resistance of the vortex plate, significantly improving the impact resistance limit and vibration reduction stability of the overall buffer structure, effectively adapting to the fluctuation requirements of different sea conditions, extending the service life of the connection device, and ensuring the safe and reliable operation of the offshore photovoltaic platform connection system.
[0030] This invention utilizes the air compression and extraction action of the buffer piston as it moves up and down within the piston hole to drive the first air channel, first air ring groove, first rubber airbag, and second air channel, second air ring groove, and second rubber airbag to achieve adaptive switching of seals: Under normal conditions, a basic seal is maintained; during movement, the seal alternately bulges and tightly adheres to the buffer rod, forming a highly efficient dynamic seal protection. When the seals of the rubber ring, first rubber airbag, and second rubber airbag fail, and seawater seeps into the buffer cylinder along the buffer rod, the rubber scraper ring can actively intercept the seawater to the liquid accumulation ring groove. The seawater flows through the liquid accumulation channel into the warning hole and gathers above the partition plate until the positive and negative conductive plates are connected to form a closed circuit. At this time, the battery-powered drive signal transmitter sends a warning to the central control system, achieving accurate early warning and timely maintenance reminders for seal failure.

[0061] Working principle: The offshore photovoltaic platform is assembled by splicing multiple floats 1 and multiple docking plates 3. Each pair of adjacent floats 1 is fixedly connected by two buffer pieces 5. During the production of docking plates 3, the length and shape can be adjusted according to actual installation requirements. The docking groove 2 and the docking plate 3 are fixed by bolts, and the bolts are inserted into the bolt holes 14 to fix the flange 506. The first photovoltaic support 11 and the second photovoltaic support 12 are respectively installed in the first photovoltaic groove 8 and the second photovoltaic groove 9 by bolts. The height of the first photovoltaic support 11 is set to be lower than the height of the second photovoltaic support 12. The photovoltaic bracket is installed in the threaded holes 13 of the first photovoltaic support 11 and the second photovoltaic support 12 by bolts, so that the photovoltaic bracket is arranged in an inclined state. The inclination angle of the photovoltaic bracket is precisely controlled by controlling the length of the docking plate 3 and the height of the first photovoltaic support 11 and the second photovoltaic support 12 during the production stage. The photovoltaic panels are subsequently installed on the photovoltaic bracket. The spliced floats 1 are connected to the bracket structure of the photovoltaic platform. A central control system is built on the photovoltaic platform to control various auxiliary equipment of the photovoltaic platform and ensure the stable and normal operation of the offshore photovoltaic platform.
[0062] The outer float 1 of an offshore photovoltaic platform often adopts an arc-shaped edge structure to adapt to the edge design of platforms with different contours, in order to meet diverse offshore deployment requirements. The outer floats 1 are connected by a buffer 5 to achieve variable angles. The buffer rod 502 and buffer piston 5018 in the buffer 5 are both designed with a cylindrical structure. The cylindrical shape gives them a degree of freedom of rotation and displacement in multiple directions, allowing the relative angle between adjacent floats 1 to be flexibly adjusted, breaking the limitations of fixed connections. In the actual construction process, the length and shape of the docking plate 3 can be precisely customized according to the preset angle requirements of the target platform, so that the angle adjustment function of the docking plate 3 and the buffer 5 can work together. The buffer 5 provides sufficient margin for the angle offset between floats 1 through the flexible movement of the cylindrical buffer rod 502 and buffer piston 5018. The docking plate 3 achieves precise positioning and fixation of adjacent floats 1 through the adapted length and shape. The two work together to achieve flexible construction of offshore photovoltaic platforms with different angles and contours, which not only ensures the stability of the platform structure, but also greatly improves the adaptability and flexibility of the platform deployment.
[0063] Sea waves cause the float 1 to rock. Under normal sea conditions, the force exerted by the float 1 on the buffer 5 is a complex compound force, which mainly includes vertical swaying force and lateral offset force. When the float 1 is subjected to such a complex compound force, the force is first transmitted to the flange 506, and then synchronously transmitted from the flange 506 to the first conical vortex plate 504, the second conical vortex plate 505, and the universal rocker arm 5012. The first conical vortex plate 504 and the second conical vortex plate 505 are arranged in a diamond shape to form a multi-directional elasticity. The core load-bearing structure for cushioning capacity: When the float 1 swings up and down, the first conical vortex plate 504 and the second conical vortex plate 505 initially dissipate the vertical force through the expansion and contraction deformation of the conical vortex structure; when the float 1 shifts to four sides, the rhomboidly arranged vortex plates precisely buffer and offset the lateral shifting force through the elastic torsion and recovery of their own vortex curved surfaces; the force is transmitted to the universal joint 5011 through the universal joint 5012, driving the magnetic flux main piston 5010 to make synchronous displacement within the magnetic flux tube 509, so that the magnetic fluid inside the magnetic flux tube 509 flows through the magnetic flux tube. 508 flows into the magnetofluid box 507. The magnetofluid compresses the magnetofluid auxiliary piston 5015 inside the magnetofluid box 507, causing the auxiliary piston 5015 to compress the magnetofluid spring 5016, forming secondary damping. During this stage, a synergistic buffering system is formed, consisting of the vortex plate elastic primary buffer and the magnetofluid damping secondary buffer. The magnetic isolation pad 5013 effectively prevents the magnetic field inside the magnetofluid tube 508 from leaking out, ensuring the stability of the magnetofluid flow. Meanwhile, the excitation coil 5014, fitted onto the magnetofluid tube 508, remains disconnected and does not actively intervene in regulation, relying on the inherent damping characteristics of the magnetofluid and the elastic deformation of the vortex plate. The transformation is adaptive and coordinated, precisely adapting to the complex combined forces under normal sea conditions, and maximizing the conversion of multi-directional combined forces into controllable vertical buffer displacement; subsequently, the second conical vortex plate 505 transmits the residual force to the buffer plate 503 and the buffer rod 502, causing the buffer rod 502 to retract into the buffer cylinder 501. The buffer rod 502 drives the buffer piston 5018 to slide up and down inside the buffer cylinder 501. The first buffer spring 5020 and the second buffer spring 5021 form a three-stage buffer through compression or stretching deformation, further improving the vibration reduction effect.
[0064] When the buoy 1 sways excessively due to sea waves, and the complex combined forces exceed the initial elastic deformation tolerance of the first conical vortex plate 504 and the second conical vortex plate 505, the displacement of the buffer rod 502 triggers the microcontroller 5024 to start. The microcontroller 5024 precisely adjusts the energizing current of the excitation coil 5014 based on the displacement signal, thereby controlling the magnetic force intensity generated by the excitation coil 5014. After being energized, the excitation coil 5014 is sleeved outside the magnetohydrodynamic tube 508, changing the rheological characteristics of the magnetohydrodynamic fluid inside the magnetohydrodynamic tube 508 through magnetic force, significantly reducing the flow velocity of the magnetohydrodynamic fluid, and causing the magnetohydrodynamic main piston 5010 and... The motion damping of the magnetohydrodynamic auxiliary piston 5015 increases dramatically. This active enhancement of magnetohydrodynamic damping is transmitted in the reverse direction to the first conical vortex plate 504 and the second conical vortex plate 505 through the universal joint 5011 and the universal rocker arm 5012, forming a synergistic enhancement mechanism of elastic bearing of the vortex plate and active magnetohydrodynamic resistance. This is equivalent to providing dynamically adjustable elastic support and strengthening the rhomboid vortex plate structure, greatly improving the deformation resistance and bearing limit of the first buffer spring 5020 and the second buffer spring 5021, thereby stably adapting to the working conditions of large waves at sea, avoiding damage to the connection structure due to excessive deformation, and ensuring the stability of the entire platform connection system.
[0065] In the marine environment, the buffer component 5 is affected by waves, and seawater can easily come into contact with the buffer component 5, which may damage the sealing performance of the buffer component 5. The first buffer spring 5020 and the second buffer spring 5021 inside the buffer cylinder 501 will be corroded by seawater, thus affecting its performance in bearing the vertical force of the float 1. Further sealing protection is achieved through the airtight component 6. If the seal fails, a warning signal is issued through the warning component 7 to prevent the buffer component 5 from losing its elastic buffering capacity.
[0066] During the production and processing stage, a set amount of gas is injected into the device through the air nozzle 6012. The gas enters the first air channel 603 or the second air channel 606 through the inflation channel 6011. The first air channel 609 connects the first air channels 603 on both sides of the buffer cylinder 501, and the second air channel 6010 connects the second air channels 606 on both sides of the buffer cylinder 501. After inflation, the airtight cap 6013 is tightened on the air nozzle 6012 to achieve a seal. The rubber ring 608 is installed inside the rubber ring groove 607 and sleeved on the buffer rod 502 to achieve a basic seal at the joint between the upper port of the buffer cylinder 501 and the buffer rod 502.
[0067] When the buffer piston 5018 moves downward inside the piston hole 5017, it compresses the air below the piston hole 5017. The air enters the first air ring groove 601 through the first air passage 603, causing the first rubber air bladder 602 inside the first air ring groove 601 to inflate further, better fitting the buffer rod 502 and achieving efficient sealing of the buffer rod 502. At the same time, the buffer piston 5018 expands the space above the piston hole 5017, and the gas inside the second air passage 606, the second air ring groove 604, and the second rubber air bladder 605 flows into the space above the piston hole 5017. At this time, the second rubber air bladder 605 maintains a basic sealing state for the buffer rod 502.
[0068] When the buffer piston 5018 moves upward inside the piston hole 5017, it compresses the air above the piston hole 5017. The air enters the second air ring groove 604 through the second air passage 606, causing the second rubber air bladder 605 inside the second air ring groove 604 to further inflate, better fitting the buffer rod 502 and achieving efficient sealing of the buffer rod 502. At the same time, a negative pressure is generated in the lower space inside the piston hole 5017, drawing out the gas inside the first air passage 603, the first air ring groove 601, and the first rubber air bladder 602. At this time, the first rubber air bladder 602 maintains a basic sealing state for the buffer rod 502. By moving the buffer piston 5018 up and down inside the piston hole 5017, the first rubber air bladder 602 and the second rubber air bladder 605 can switch to seal, ensuring sealing reliability.
[0069] When the seal of the rubber ring 608, the first rubber airbag 602, and the second rubber airbag 605 on the buffer rod 502 fails, seawater will enter the buffer cylinder 501 along the buffer rod 502. The rubber scraper ring 702 intercepts the seawater adhering to the surface of the buffer rod 502 and traps it in the liquid accumulation ring groove 701. The seawater inside the liquid accumulation ring groove 701 flows into the warning hole 704 through the liquid accumulation channel 703. The seawater gradually gathers above the partition plate 705 inside the warning hole 704 until it comes into contact with the positive conductive plate 709 and the negative conductive plate 7010. The positive conductive plate 709 and the negative conductive plate 7010 form a closed circuit through the seawater. At this time, the battery 707 releases electricity to power the signal transmitter 706. The signal transmitter 706 sends a warning signal to the central control system of the photovoltaic platform to remind the staff to replace the buffer component 5 in time.
