Description

Technical Field

[0001] This invention belongs to the field of marine photovoltaic technology, and in particular relates to a compartmentalized marine floating platform device and its working method. Background Technology

[0002] Traditional fixed offshore platforms are strictly limited by water depth and seabed topography, requiring complex seabed piling and gravity foundation construction. They are only suitable for shallow water operations and cannot meet the needs of deep-sea development. In contrast, self-floating offshore platforms rely on mooring systems for positioning, breaking through the constraints of water depth operations. They can adapt to the complex operating environments of deep-sea areas ranging from hundreds to thousands of meters. Among them, floating platforms, with their advantages of standardized modular assembly, no need for seabed construction, and adaptive adjustment of sea conditions through water pumping, can flexibly adapt to different operational scales and functional requirements. They provide an important technical path for the efficient and low-cost development of marine resources and the development of diversified marine industries, and have now become the mainstream development direction for deep-sea offshore wind power installation and operation and maintenance.

[0003] Current offshore floating platform pipeline designs have technical shortcomings. The use of a single, integral pipeline structure leads to uneven water flow within the pipeline during operation. In the complex and harsh conditions of deep-sea environments, this uneven flow can cause overall structural imbalance, easily leading to platform capsizing and significantly reducing the safety and stability of offshore operations. Furthermore, the violent surges of ocean waves directly impact the floating platform's structure and mooring system, potentially causing damage to the mooring system and surface structure over time, drastically shortening its lifespan. This also severely hinders the normal operation of offshore wind power installation and maintenance, failing to meet the demands of high-intensity, high-stability operations in deep-sea environments.

[0004] It is evident that existing offshore floating platform pipelines suffer from technical defects such as uneven water flow within the pipes, which can easily lead to platform capsizing; equipment damage in severe sea conditions; and poor operational stability. Summary of the Invention

[0005] This invention provides a compartmentalized offshore floating platform device and its operating method. Using this floating platform device can solve the technical defects of existing offshore floating platform pipelines, such as uneven water flow in the pipes which can easily cause the platform to capsize, equipment damage in severe sea conditions, and poor operational stability.

[0006] To achieve the above objectives, the present invention employs the following technical content: A compartmentalized offshore floating platform device includes multiple floating platforms; Multiple floating platforms are connected and arranged in an array; The floating platform adopts a compartmentalized structure, comprising multiple compartments; The silo body includes an upper pipe and a bottom pipe that are connected to each other; A water pump is installed inside the upper pipe; the water pump is used to pump water or drain water from the corresponding compartment to adjust the water depth of the compartment. The adjacent bottom pipes corresponding to adjacent compartments are connected by compartment units; the compartment units are used to achieve connection and independence between adjacent compartments by opening and closing.

[0007] Furthermore, it also includes collectors; A square plate is provided on the top of the floating platform; The collector is fixed to the square plate; The collector is connected to an anchor chain; One end of the anchor chain is connected to the retrieval device, and the other end extends downward from the side of the floating platform and is fixed to the seabed.

[0008] Furthermore, a collector is provided at each of the top corners of each of the aforementioned floating platforms.

[0009] Furthermore, the retrieval device includes an electric winch; the electric winch is connected to one end of the anchor chain and can drive the anchor chain to wind or release, in order to adjust the position and attitude of the floating platform.

[0010] Furthermore, a truss is provided between adjacent silos; the truss is located at the connection between adjacent bottom pipes; One end of the truss is connected to the connection of adjacent bottom pipes, and the other end is connected to the intersection of multiple upper pipes.

[0011] Furthermore, flow-guiding damping plates are evenly distributed along the axial direction of the pipe body in the inner cavities of the bottom pipe and the upper pipe.

[0012] Furthermore, the compartment unit integrates a throttling valve body.

[0013] Furthermore, an elastic buffer connector is provided at the splicing position of two adjacent floating platforms; the elastic buffer connector includes an elastic tie rod and a rubber buffer pad.

[0014] A method for operating a compartmentalized offshore floating platform device, based on the aforementioned compartmentalized offshore floating platform device, includes: Based on the sea conditions and the attitude control requirements of the floating platform, the compartment units between adjacent compartments are adjusted so that the compartment units are closed and each compartment is independent of the others. Start the water pump inside the upper pipe of the corresponding tank body, and use the water pump to inject water into the tank body composed of the upper pipe and the bottom pipe, or pump the seawater out of the tank body, and adjust the draft of the floating platform by changing the water storage volume of the tank body. When a water pump fails or when it is necessary to balance the overall counterweight of the floating platform, the corresponding compartment unit is activated to connect the bottom pipes of adjacent compartments. In the event of a water pump failure, water is injected or pumped into the compartment corresponding to the faulty water pump through the connecting bottom pipe, ensuring that all compartments can regulate the water storage volume and continuously control the overall draft of the floating platform.

[0015] Furthermore, the compartmentalized offshore floating platform device also includes a retrieval device fixed to the floating platform, the retrieval device being connected to an anchor chain; the operating method further includes: The anchor chain is wound or released by the retractor, which, in conjunction with the water pump adjustment, adjusts the position and attitude of the floating platform.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This invention provides a compartmentalized offshore floating platform device, which consists of multiple floating platforms connected in an array and employs a compartmentalized structure. Each compartment is connected by an upper and lower pipe and has an internal water pump to adjust the draft. The connectivity between adjacent compartments is controlled by compartmentalized units. This device's compartmentalized design allows for independent adjustment of the water volume in each compartment, achieving local balance adjustment of the floating platform. The compartmentalized units can be dynamically opened and closed, isolating compartments in harsh sea conditions to reduce water flow impact and thus avoid uneven water flow within the overall pipeline. This device effectively solves the risk of platform capsizing caused by uneven water flow within the pipeline in existing technologies, significantly improves the stress balance and overall stability of the floating platform in complex sea conditions, reduces damage to mooring systems and structures, extends equipment lifespan, and ensures the stable operation of high-intensity tasks such as offshore wind power installation. This invention also provides a method for operating a compartmentalized offshore floating platform device. Based on the aforementioned compartmentalized offshore floating platform device, the opening and closing of compartment units is controlled according to sea conditions and attitude requirements to switch between independent and connected states of the compartments. The water pumps in each compartment are operated to independently adjust the water storage volume. Under specific circumstances, the compartment units are opened to achieve cross-compartment water flow distribution. This method, by actively controlling the opening and closing of the compartment units, enables the device to achieve precise local draft adjustment with independent compartments during normal operation, thereby directly optimizing the stress distribution of the floating platform. In case of pump failures or other abnormalities, emergency water flow distribution between adjacent compartments is achieved using connected bottom pipes, providing redundant adjustment capabilities for the system. This method effectively overcomes the inherent defects of uneven water flow in traditional integral pipelines, significantly enhancing the attitude stability and anti-capsulation capability of the floating platform under harsh sea conditions. Simultaneously, the emergency function ensures continuous and safe operation, reducing the risk of equipment damage, and ultimately improving the operational reliability and service life of the entire floating platform device under complex deep-sea conditions.

[0019] To make the technical problems solved by the present invention, the technical solutions, and the beneficial effects clearer, the following specific embodiments provide a further detailed description of the present invention. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of the invention.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0022] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0023] As mentioned in the background section, currently, in severe sea conditions, violent waves can easily damage mooring systems and the surface of floating platforms. Due to uneven water flow within the pipes, offshore floating platforms are prone to capsizing.

[0024] To address the aforementioned issues, this embodiment provides a compartmentalized offshore floating platform device that can divide the platform's pipes into compartments to ensure uniform water flow within the pipes. By pumping water out, the buoy can submerge or rise, preventing damage to the mooring system and the platform surface from violent waves in severe sea conditions. It also avoids platform capsizing caused by uneven water flow within the pipes.

[0025] For example, such as Figure 1 As shown, this embodiment provides a compartmentalized offshore floating platform device, including multiple floating platforms 7. The multiple floating platforms 7 are interconnected and arranged in an array. A single compartmentalized offshore floating platform device consists of at least four floating platforms 7. The overall floating body is composed of multiple parallel-arranged individual floating platforms 7 spliced ​​together, with a regular overall structure and a high degree of modularity. The floating platform 7 adopts a compartmentalized structure, with multiple independent compartments inside. The compartmentalization equipment of a single floating platform 7 can evenly divide its interior into four independent compartments. Each compartment is composed of an interconnected upper pipe 4 and a bottom pipe 3. The floating platform 7 is made of steel pipe. At least four water pumps 8 are correspondingly configured inside the upper pipe 4 of a single floating platform 7. The entire device is equipped with at least sixteen water pumps 8. Each water pump 8 is responsible for the pumping and draining operations of one compartment area. Each upper pipe 4 is equipped with a water pump 8, which can accurately pump or drain water from the corresponding compartment. By changing the water storage capacity inside the compartment formed by the upper pipe 4 and the bottom pipe 3, the draft of the corresponding compartment and the entire floating platform 7 can be precisely adjusted.

[0026] like Figure 3 As shown, compartment units 6 are installed between adjacent bottom pipes 3 corresponding to adjacent compartments. Compartment units 6 can achieve waterway connectivity and independent state switching between adjacent compartments through their own opening and closing switching actions. Explained, this scheme adopts an array-type compartmentalized modular floating platform structure. Precise buoyancy control is achieved through independent pumps 8 in each compartment, and the compartment opening and closing is controllable by the compartment units 6. This not only enables differentiated adjustment of the draft in different areas of the floating platform to adapt to attitude control requirements under different sea conditions, but also improves the operational fault tolerance of the device through multi-compartment redundancy design. It avoids tilting and capsizing problems caused by uneven buoyancy in the local area of ​​the floating platform from the structural root, effectively solving the defects of traditional integral floating platforms such as turbulent water flow and low control precision, and significantly improving the floating stability of the floating platform. It can be seen that this embodiment can change the height of the floating platform by changing the water suction state of the pumps 8, avoiding the floating platform from being continuously subjected to excessively strong ocean currents and wind forces, thereby ensuring the stability and safety of the device.

[0027] It should be explained that one water pump 8 can ensure the pumping of water to one compartment area. By pumping water from each compartment, the stability of the entire compartmentalized offshore floating platform device is better ensured, thereby accelerating the transformation of the floating box-type offshore photovoltaic platform. On this basis, by setting up series components, if one of the water pumps 8 fails, the outlet of the compartment unit 6 can be adjusted to direct the water flow to the upper pipe 4 connected to the failed water pump 8. Although this will increase the time spent on the pumping process, it ensures that all upper pipes 4 can be successfully filled and drained.

[0028] As another preferred embodiment, such as Figure 2 and Figure 4As shown, the compartmentalized offshore floating platform device also includes a hauler 1. A square plate 9 is fixedly installed on the top of the floating platform 7, and the hauler 1 is fixedly installed on the surface of the square plate 9. The square plate 9 provides a flat and stable mounting base for the hauler 1, preventing problems such as loosening, displacement, or detachment of the hauler 1 under complex offshore conditions. The hauler 1 is driven by an anchor chain 2. One end of the anchor chain 2 is fixedly connected to the hauler 1, and the other end extends vertically downward from the side of the floating platform 7 and is firmly fixed to the seabed. Specifically, the device is equipped with multiple haulers 1, which are evenly distributed at the edge of the compartmentalized offshore floating platform device, fully covering the floating platform's operating area. Explained, the tension control mooring mechanism, formed by the retrieval device 1 and the anchor chain 2, provides comprehensive seabed restraint for the arrayed floating platforms 7. This effectively counteracts the horizontal thrust and impact forces from sea winds, currents, and waves, limiting the horizontal displacement and drift of the floating platforms 7 and keeping them consistently within the designated operating area, ensuring the accuracy and stability of their operational position. In other words, thanks to the retrieval device 1 and the anchor chain 2, the entire compartmentalized offshore floating platform device remains safe and stable on the sea surface or seabed, regardless of the restart status of the upper pipe 4 and the bottom pipe 3.

[0029] As another preferred embodiment, a retrieval device 1 is installed at each of the top corners of each floating platform 7, achieving full coverage of the retrieval mechanism at the top corners of a single floating platform 7. Explained, symmetrically arranging the retrieval devices 1 and matching anchor chains 2 at the top corners of the floating platform 7 forms a multi-point, symmetrical vertical mooring restraint system. This system can evenly distribute wave and wind loads from multiple directions around the floating platform 7, preventing problems such as attitude deflection and localized tilting caused by excessive force on one side of the floating platform 7, and further enhancing the overall positioning stability and anti-disturbance capability of the floating platform.

[0030] Specifically, the core of the hauler 1 adopts an electric winch structure, which is fixedly mounted on the square plate 9 of the floating platform 7. The output end of the electric winch is fixedly connected to one end of the anchor chain 2, and the winding or releasing action of the anchor chain 2 can be achieved through forward and reverse drive. In other words, as a mature and controllable drive component, the electric winch is precise and responsive. It can adjust the extension length and tension of the anchor chain 2 in real time according to sea conditions and the attitude requirements of the floating platform, precisely cooperating with the buoyancy adjustment structure to complete the lifting and lowering of the floating platform 7 and the fine-tuning of its attitude. This enables precise dynamic control of the position and attitude of the floating platform 7, adapting to complex and ever-changing marine conditions.

[0031] As another preferred embodiment, a truss 5 is provided between adjacent compartments. The truss 5 is specifically installed at the connection point of adjacent bottom pipes 3. One end of the truss 5 is fixedly connected to the docking position of the adjacent bottom pipes 3, and the other end is fixedly connected to the intersection position between multiple upper pipes 4. Furthermore, a reinforcing truss 5 is fixedly assembled at the compartment connection position of each independent floating platform 7. Explained as, since the floating platform 7 adopts a compartmentalized steel pipe structure, the splicing of pipes and the opening of compartments will cause a loss of overall structural strength. The truss 5 can build a three-dimensional support frame between the bottom pipes 3 and the upper pipes 4, and comprehensively reinforce the pipe splicing structure of the floating platform 7, effectively improving the overall structural rigidity and deformation resistance of the floating platform 7, buffering the structural stress brought by the impact of sea waves, avoiding cracking and deformation at the pipe connection point, and ensuring the structural integrity of the floating platform during long-term offshore operations.

[0032] In this embodiment, both the bottom pipe 3 and the upper pipe 4 have flow-guiding damping plates evenly distributed along the axial direction of the pipe body inside their inner cavities. The flow-guiding damping plates are integrated with the pipe body and cover the entire water passage of the tank. Explained, during the pumping and filling process of water pump 8, the flow-guiding damping plates can regulate and dampen the seawater flow inside the pipe, effectively suppressing unstable water flow phenomena such as turbulence, eddies, and vortices inside the tank, ensuring that the water volume adjustment process of each tank is uniform and stable, eliminating platform shaking and tilting problems caused by sudden changes in local water flow and buoyancy, and completely avoiding the risk of platform capsizing caused by uneven water flow inside the pipe.

[0033] As another preferred embodiment, a throttling valve body is integrated on the compartment unit 6, and the throttling valve body is integrated with the on / off structure of the compartment unit 6. Explained, the integrated throttling valve body can precisely control the flow area, water velocity, and flow rate of the water passage connecting adjacent compartments. During compartment connection water adjustment and fault water replenishment operations, it can achieve a smooth water flow transition, avoid the impact of instantaneous large flow of water causing violent fluctuations in the attitude of the floating platform, and at the same time, it can accurately match the water adjustment rate according to sea conditions, greatly improving the accuracy and stability of the floating platform buoyancy adjustment.

[0034] Specifically, elastic buffer connectors are installed at the joints of two adjacent floating platforms 7. These connectors consist of elastic rods and rubber buffer pads, flexibly adapting to the gaps between the floating platforms. In other words, the multiple floating platforms 7 arranged in an array achieve flexible jointing through these elastic buffer connectors, replacing the traditional rigid connection structure. When wave impacts or current disturbances cause squeezing or pulling forces between the floating platforms 7, the elastic rods' expansion and contraction, combined with the damping energy absorption of the rubber buffer pads, effectively absorb and buffer impact loads, eliminate stress concentration and rigid collision wear at the joints, prevent loosening or damage at the platform joints, and improve the overall stability and service life of the array of floating platforms.

[0035] In this embodiment, the working method of the above-mentioned compartmentalized offshore floating platform device is based on the above-mentioned floating platform device. During actual offshore operations, the staff can adjust the compartmentalized units 6 between adjacent compartments according to the real-time sea conditions and the attitude control requirements of the floating platform 7, so that all compartmentalized units 6 are kept in a completely closed state. At this time, the water channels between each compartment are isolated from each other, and each compartment is in an independent working state. Then, the water pump 8 inside the upper pipe 4 of the corresponding compartment is started. The water pump 8 is used to inject seawater into the sealed compartment composed of the upper pipe 4 and the bottom pipe 3, or to pump the seawater stored in the compartment outward. By precisely changing the water storage volume of each compartment, the draft of each section of the floating platform 7 is adjusted differentially. Under normal sea conditions with gentle currents and small waves, the water pump 8 can be used to adjust so that the compartment is not fully filled with water, reducing the buoyancy of the floating platform 7, reducing the distance between the top surface of the floating platform and the sea level, reducing the overall windward area, and reducing the force of sea wind and waves. Under severe sea conditions with strong currents and large waves, the water pump 8 can be used to fully fill the compartment with water, increasing the buoyancy of the floating platform 7 and reducing the overall height of the floating platform. Explained, the compartmentalized independent control mode enables precise zonal adjustment of the buoyancy and draft of the floating platform, adapting to the operational needs of different sea conditions. Under normal sea conditions, it reduces wind stress and improves stability, while under severe sea conditions, it avoids danger by sinking, effectively preventing waves from surging onto the floating platform and eroding and damaging the platform structure and mooring system, thus ensuring the safety of floating platform operations in all aspects.

[0036] It should be noted that the upper pipe 4 is provided with a pumping and draining hole for pumping and draining water, which is used to cooperate with the water pump 8 to realize the water injection and drainage work; since the pumping and draining hole is a mature technology, it will not be described in detail here.

[0037] Explainedly, when pump 8 malfunctions and cannot pump or drain water normally, or when it is necessary to balance the overall counterweight of the floating platform 7 and uniformly adjust the overall buoyancy, the corresponding compartment unit 6 can be activated to connect the bottom pipes 3 of adjacent compartments, forming a continuous cross-compartment water flow channel, breaking the limitation of independent operation of a single compartment. Explainedly, by activating the compartment unit 6 to achieve interconnection of waterways between multiple compartments, the water storage of each compartment can be quickly balanced, the overall counterweight of the floating platform can be calibrated, solving the problem of difficult correction of counterweight imbalance under conventional independent control mode, and providing a backup water diversion channel for the malfunctioning compartment, realizing emergency compensation for malfunction conditions.

[0038] Specifically, when one or more water pumps 8 fail, the remaining normally functioning water pumps 8 within the system can be used to inject or pump water into the compartment corresponding to the failed pump 8 via the connected bottom pipe 3. Even though cross-compartment water transfer slightly increases the time required, it can still continuously adjust the water storage volume of the failed compartment, ensuring that all compartments of the floating platform 7 can achieve water volume regulation and maintain the stable control of the overall draft of the floating platform 7 without interruption. This operating mode provides the system with redundant pump failure control capabilities, ensuring the normal operation of the buoyancy adjustment function without shutdown for maintenance. This significantly improves the system's fault tolerance and continuous operation capability in complex marine conditions, avoiding problems such as loss of buoyancy, attitude instability, and operational interruption caused by sudden equipment failures.

[0039] As another preferred embodiment, the working method of this compartmentalized offshore floating platform device is also equipped with a coordinated control operation of the haul-in device 1 and the anchor chain 2. The haul-in device 1 is fixed to the square plate 9 of the floating platform 7 and connected to the anchor chain 2. In actual operation, the electric winch of the haul-in device 1 drives the anchor chain 2 to wind or release, adjusting the tension and extension length of the anchor chain 2. This works in conjunction with the water pump 8's adjustment of the container water volume and buoyancy control to jointly complete the position locking and precise attitude adjustment of the floating platform 7. Explained, the water pump 8 realizes the basic control of the floating platform 7's buoyancy height and buoyancy, while the haul-in device 1 and the anchor chain 2 realize the constraint correction of the floating platform 7's horizontal position and overall attitude. The two work together to achieve multi-dimensional precise control of the floating platform. Regardless of whether the container is filled or drained, the safety and stability of the floating platform can be guaranteed during normal operation at sea level or when it sinks to avoid danger, completely avoiding the risk of mooring system overload damage and floating platform instability and capsizing under severe sea conditions. Therefore, the above-described working method changes the distance between the top surface of the modular floating platform and the sea level by altering its draft, thus preventing waves from surging onto the platform. Specifically, when the current is relatively calm and the waves are small, the water pump 8 keeps the upper pipe 4 and the bottom pipe 3 partially filled with water. In this state, the buoyancy of the modular floating platform is lower, the distance between its top surface and the sea level is smaller, and the overall windward area is smaller, resulting in less force from the sea breeze and improved stability. In sea conditions with strong currents and large waves, the water pump 8 releases water into the upper pipe 4 and the bottom pipe 3, completely filling them. This increases the buoyancy of the modular floating platform, and together with the retrieval device 1 and the anchor chain 2, helps it sink to the seabed, preventing seawater from damaging its stability and safety. On the other hand, the compartment unit 6 can also improve the floating stability and water flow uniformity of the compartment-type offshore floating platform, and reduce the impact of waves on the compartment-type offshore floating platform. In addition, this embodiment also provides a retrieval device 1 and an anchor chain 2, which can constrain the compartment-type offshore floating platform and ensure that it can be supported.

[0040] In summary, this invention provides a compartmentalized offshore floating platform device and its operating method, which has the following advantages compared to existing offshore floating platforms: In this invention, under calm sea conditions, pump 8 slightly pumps water to ensure a relatively small and uniform water flow within the upper pipe 4 and bottom pipe 3, guaranteeing the platform remains stably positioned on the sea surface. However, in rough sea conditions with strong currents and high waves, pumps 8 at each compartment operate simultaneously, filling the steel pipes (upper pipe 4 and bottom pipe 3) with seawater, causing the platform to sink to the seabed and preventing damage to the platform in adverse sea conditions. By dividing the floating platform into compartments, water flows smoothly within the steel pipes, preventing seawater from tilting towards one side of the platform. This design effectively prevents seawater from impacting the floating platform under extreme sea conditions, providing a stable power generation environment for subsequent offshore wind power platforms.

[0041] The above embodiments are merely one of the implementation methods for achieving the technical solution of the present invention. The scope of protection claimed by the present invention is not limited to this embodiment, but also includes any variations, substitutions and other implementation methods that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention.
