Description

Technical Field

[0001] This invention belongs to the field of offshore wind power technology, specifically relating to a fireproof partition composite structure for an energy storage compartment of an offshore wind power platform. Background Technology

[0002] As offshore wind power expands into deeper waters, integrating energy storage systems into wind turbine platforms has become a crucial technological approach for enhancing the grid's proactive support capabilities and achieving multi-energy synergy. However, lithium-ion battery energy storage systems, when experiencing thermal runaway, not only release large amounts of flammable gases (such as H2, CO, and CH4), but can also ignite violent fires with flame temperatures exceeding 1000°C. If a fire breaks out in the energy storage compartment and rapidly spreads to critical equipment such as the turbine tower, cable trays, and main transformer, it can have catastrophic consequences, potentially even destroying the entire turbine.

[0003] Existing technologies focus primarily on the impact of external thermal runaway on the energy storage compartment, neglecting the external isolation required to prevent thermal runaway. Furthermore, fireproof partition structures only consider simple fire-resistant material partitions, separating structural load-bearing from fireproof and heat-insulating functions, thus ignoring the impact on structural stability under thermal runaway conditions.

Detailed Implementation

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0019] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings: Example 1 See Figure 1 This invention provides a fireproof partition composite structure for an energy storage compartment of an offshore wind power platform, used for the separation of the energy storage compartment. The structure includes a steel frame, fire-resistant plates 4, and a first sealing assembly. The internal space of the steel frame is used to house the energy storage compartment. Multiple fire-resistant plates 4 are mounted on the frame of the steel frame. Each fire-resistant plate 4 includes an outer steel plate 4a, a fire-resistant layer 4b, and an inner steel plate 4c, which are stacked sequentially. The inner steel plate 4c is located on the side closest to the energy storage compartment. The first sealing assembly is located at the joint between adjacent fire-resistant plates 4.

[0021] In this embodiment, fire-resistant panels are installed using a steel frame structure, integrating structural support and fireproof partition functions to improve the structural stability of the composite structure under thermal runaway. The energy storage chamber is located within the three-dimensional space formed by the steel frame structure, which is covered by fire-resistant panels. The fire-resistant panels are arranged in a layered structure, with the inner steel plate on the side closest to the energy storage chamber providing resistance to flame impact and mechanical damage in the event of thermal runaway. The outer steel plate provides structural rigidity, protecting the fire-resistant layer that plays a core heat insulation role in the middle from collision damage, while also serving as a reflective layer for radiant heat from the unexposed side, thus improving the fireproof partition effect of the composite structure under thermal runaway.

[0022] The fire-resistant board 4 is connected to the frame using a self-adjusting limiting clamp or a pressure plate clamp. This connection structure allows for slight displacement release of the panel under thermal expansion conditions, while limiting the detachment and excessive deformation of the fire-resistant board, thus balancing fire resistance integrity and thermal deformation adaptability. The fire-resistant layer 4b in the middle of the fire-resistant board 4 is made of beaded silicon crystal fire-resistant board, which is fixed between the inner (fire-exposed surface) and outer (unexposed surface) of the steel structure load-bearing frame by bolts or special clamps, forming a sandwich composite structure of "outer steel plate + middle fire-resistant board + inner steel plate", as shown in the attached figure. Figure 2As shown. The outer steel plate 4a provides structural rigidity, protects the fire-resistant layer 4b from impact damage, and also serves as a reflective layer for radiant heat from the unexposed surface. The inner steel plate 4c provides resistance to flame impact and mechanical damage, and acts as a protective layer for the fire-resistant plate. Both the inner and outer steel plates can be made of galvanized steel plates, weathering steel plates, or corrosion-resistant Q235 steel plates with a thickness of 3-4mm to improve the flame impact resistance of the exposed surface, the protection capability of the unexposed surface, and the overall wind vibration resistance. The intermediate fire-resistant layer is the core insulation layer, made of perlite silicon crystal fire-resistant board with a thickness of 20-30mm, which features non-combustibility, low thermal conductivity, lightweight and high strength, and high water repellency.

[0023] Furthermore, the fire-resistant layer 4b can adopt a composite structure of perlite silica refractory board and aerogel felt, that is, a 5-10mm thick aerogel felt is laminated on the surface of the perlite silica refractory board to further reduce the thermal conductivity and improve the heat insulation performance. A 3-5mm thick ceramic fiber paper can be set between the outer steel plate and the fire-resistant layer as a buffer layer to absorb the stress caused by the difference in thermal expansion and prevent the fire-resistant board from cracking at high temperature. That is, the fire-resistant board 4 also includes a buffer layer, which is set between the outer steel plate 4a and the fire-resistant layer 4b, and the buffer layer is made of ceramic fiber paper.

[0024] In one embodiment, to ensure the reliability of the connection between the fire-resistant boards 4 and the overall airtightness, a first sealing component is provided, as shown in the attached figure. Figure 3 As shown, the first sealing assembly includes a steel pressure strip 5, ceramic fiber cotton 6, and joint sealant 7. The steel pressure strip 5 is installed at the joint of adjacent fire-resistant plates 4 to press and fix the fire-resistant plates 4. The ceramic fiber cotton 6 fills the interior of the joint, and the joint sealant 7 is applied to the outer surface of the joint. In the above embodiment, at the joint between the plates, the connecting edges of adjacent fire-resistant plates 4 are pressed and fixed by galvanized steel pressure strip 5. The galvanized steel pressure strip 5 can adopt an L-shaped or Z-shaped structure to improve the constraint capacity and installation stability of the joint. The steel pressure strip 5 is made of corrosion-resistant metal material or is treated with anti-corrosion coating to enhance its service life in marine environments. The gap between adjacent fire-resistant plates 4 is filled with high-temperature resistant ceramic fiber cotton 6, and the outer surface is covered with high-temperature resistant sealant, i.e., joint sealant 7, thus forming a flexible joint structure that combines heat insulation, sealing, and displacement adaptability. This structure can suppress the propagation of flames and high-temperature smoke through the plate joints under high-temperature fire conditions and allows the plates to deform to a certain extent when heated without failing.

[0025] In one embodiment, considering that the installation and use of the energy storage compartment involves the laying of cables, pipes, and other penetrating components, in order to ensure overall airtightness, as shown in the attached... Figure 4As shown, a second sealing component is added to seal the penetration portion. Specifically, the fireproof partition composite structure also includes a second sealing component, which is located at the penetration portion of the fireproof partition composite structure. Specifically, the second sealing component includes a fireproof sealing module 8 and a penetration sealant 9. The fireproof sealing module 8 is located at the penetration portion and surrounds the penetration, while the penetration sealant 9 is applied to the outside of the fireproof sealing module 8. In the above embodiment, at the location where cables, pipes, or other penetrations pass through the fireproof partition, a fireproof sealing module 8 is installed around the penetration, and a high-temperature resistant sealant, i.e., the penetration sealant 9, is applied to the outside of the fireproof sealing module 8. The fireproof sealing module 8 can be made of an intumescent fireproof material, which can expand and seal the gap between the penetration and the fireproof partition under fire-induced heating conditions, thereby preventing the spread of flames, hot smoke, and high-temperature airflow along the penetration hole. The penetration sealant 9 further improves the normal sealing performance and the sealing integrity under fire-resistant conditions at this location.

[0026] In one embodiment, to improve the stability of the overall frame, the steel structure frame is set as a three-dimensional frame and is composed of beams and columns. Specifically, the steel structure frame includes a wind turbine duct frame platform base beam 1, a fireproof partition beam 2 for the energy storage compartment, and a fireproof partition column 3 for the energy storage compartment. The fireproof partition beam 2 for the energy storage compartment is located above the wind turbine duct frame platform base beam 1, and the two ends of the fireproof partition column 3 for the energy storage compartment are respectively connected to the fireproof partition beam 2 for the energy storage compartment and the wind turbine duct frame platform base beam 1. As described above, the crossbeam 1 of the bottom plate of the wind turbine duct frame platform serves as the platform's foundation load-bearing component, providing the installation foundation for the entire fireproof partition composite structure. The fireproof partition crossbeam 2 of the energy storage compartment and the fireproof partition column 3 of the energy storage compartment together constitute the steel structure load-bearing skeleton of the fireproof partition. The fireproof partition column 3 of the energy storage compartment is arranged vertically and fixedly connected to the crossbeam 1 of the bottom plate of the wind turbine duct frame platform, while the fireproof partition crossbeam 2 of the energy storage compartment is arranged horizontally and connected between adjacent fireproof partition columns 3 of the energy storage compartment, thus forming a stable frame-type load-bearing system. With the installation of fire-resistant plates, the energy storage compartments are effectively covered, effectively preventing the spread of flames, high-temperature smoke, and heat radiation to adjacent equipment areas in the event of thermal runaway or fire, while also withstanding certain wind loads, vibration loads, and fire thermal shock.

[0027] Furthermore, the cross-sectional dimensions and wall thickness of the columns and horizontal beams are calculated and determined based on the actual load, installation location, and the most unfavorable working conditions of fire thermal shock. For the windward side bearing a large wind load, the cross-sectional dimensions can be appropriately increased, the column spacing can be increased, or diagonal bracing can be added. That is, the steel structure frame also includes a diagonal bracing structure, which is set between the fireproof partition column 3 of the energy storage compartment and the horizontal beam 1 of the bottom plate of the wind turbine duct frame platform and / or between the fireproof partition column 3 of the energy storage compartment and the fireproof partition beam 2 of the energy storage compartment. For the non-windward side, the cross-section can be optimized to reduce the structural weight while ensuring structural stability.

[0028] In one embodiment, the fireproof partition beam 2 and the fireproof partition column 3 of the energy storage compartment can be made of square steel pipes, I-beams, or other steel components, and can be connected by welding or high-strength bolts to form an integral load-bearing frame. The surface of the steel components can be coated with a multi-layer heavy-duty anti-corrosion coating system consisting of primer, intermediate paint, and topcoat to improve its resistance to salt spray corrosion.

[0029] In one embodiment, the fireproof partition composite structure further includes stiffening ribs 10 and bolts 11. The stiffening ribs 10 are disposed opposite each other at the bottom of the fireproof partition column 3 of the energy storage compartment, and the bolts 11 connect the stiffening ribs 10 and the crossbeam 1 of the bottom plate of the wind turbine duct frame platform. As described above, see attached... Figure 5 As shown, the bottom of the fireproof partition column 3 of the energy storage compartment is reliably connected to the crossbeam 1 of the wind turbine duct frame platform base plate via stiffening ribs 10 and high-strength bolts 11. Specifically, the fireproof partition column 3 of the energy storage compartment is vertically installed, with its bottom end supported at the platform connection point. The stiffening ribs 10 are located on both sides or opposite to the mounting base plate between the fireproof partition column 3 and the mounting base plate to enhance the local stiffness and load-bearing capacity of the column root node, preventing local buckling or connection instability of the column under wind load, vibration load, or fire heat. The bolts 11 are made of corrosion-resistant metal or are treated with anti-corrosion to enhance their service life in the marine environment. They are installed between the connecting plate and the crossbeam 1 of the wind turbine duct frame platform base plate and can be equipped with anti-loosening washers to improve the node's resistance to vibration loosening and long-term service reliability. This connection method allows for rapid installation, disassembly, and maintenance between the fireproof partition structure and the main platform structure, while meeting the requirements for structural stability, durability, and maintainability in the marine environment.

[0030] In one embodiment, to adapt to the construction and maintenance needs of offshore platforms, the fireproof partition composite structure adopts a modular design: First, the fireproof partition is divided into several standard unit modules, with a unit width of 1.2-1.5m and a height matching the floor height. The modules are connected by "male and female slots" and bolts. Second, for hoisting and installation, the weight of each module is controlled within 500kg to facilitate offshore hoisting and manual handling. The modules are pre-set with hoisting points and positioning guide pins to ensure installation accuracy. Third, for replaceability, when a single panel or module is damaged, it can be disassembled and replaced independently without affecting adjacent modules. Operational space is reserved at key connection nodes to facilitate maintenance and repair. Finally, for operation and maintenance identification, the modules are equipped with numbered identifiers, fire resistance limit signs, or status record identifiers to record the installation location, installation date, maintenance records, and sensing unit status, which facilitates the operation and maintenance management of offshore platforms.

[0031] Example 2 To achieve an integrated design of "steel structure load-bearing frame + fire-resistant insulation layer + node collaborative constraint + multimodal hazard perception," a composite protection system is formed that integrates structural load-bearing, flame blocking, heat transfer attenuation, heat radiation reduction, node status feedback, and service status monitoring. This transforms traditional passive protection into active sensing protection by adding sensing units for real-time monitoring. Specifically, the fireproof partition composite structure also includes sensing units, which are installed at key nodes of the fireproof partition composite structure to collect status information from these key nodes. While meeting the functions of fire resistance insulation, structural load-bearing, and fire separation, the system senses the hazards experienced by the fireproof partition itself and its external service environment, including flame impact, heat radiation, smoke spread, structural deformation, node loosening, moisture intrusion, and salt spray corrosion. It can also be linked with the platform's fire protection, alarm, remote operation and maintenance management system, realizing the transformation from a traditional passive fireproof partition structure to a new type of fireproof partition structure with comprehensive environmental hazard perception and structural status feedback.

[0032] As attached Figure 6 As shown, the perception feedback system includes a perception layer, a decision-making layer, and an execution layer. Specifically, the perception layer may include multi-source signal perception units, such as structural state perception units, thermal radiation or temperature perception units, flue gas or sealing state perception units, and environmental state perception units. These units are installed at key nodes, such as composite laminated fire-resistant boards, panel joints, through-hole sealing locations, platform connection interfaces, and key nodes of the steel structure. Structural condition sensing units can employ strain gauges, vibration sensors, displacement sensors, or bolt preload monitoring elements; temperature / thermal radiation sensing units can employ thermocouples, high-temperature resistant thin-film temperature sensors, infrared temperature measurement units, heat flow sensors, or distributed fiber optic temperature measurement units; flue gas sensing units can employ smoke sensors, CO sensors, H2 sensors, VOC sensors, or composite gas detectors; sealing condition sensing units can employ pressure sensors, differential pressure sensors, airtightness detection sensors, micro-leakage detection sensors, or sealant condition monitoring elements; environmental condition sensing units can employ humidity sensors, condensation sensors, corrosion monitoring plates, corrosion potential or rate sensors to monitor potential comprehensive risks.

[0033] Specifically, the structural state sensing unit is used to collect node connection status information of key nodes, the temperature sensing unit is used to collect heat status information of key nodes, the sealing status sensing unit is used to collect sealing status information of key nodes, and the environmental state sensing unit is used to collect environmental status information of key nodes.

[0034] The aforementioned multimodal sensing units can be connected to the decision-making layer and communicate with the state perception feedback linkage system to comprehensively judge the state of key nodes, such as the heat status of fireproof partitions, the sealing status of joints, the connection status of nodes, structural deformation, and environmental conditions such as moisture intrusion and salt spray corrosion risk. The units also provide state feedback to the remote execution feedback system, and output state feedback, early warning prompts, inspection suggestions, or module replacement suggestions to the remote fire alarm system, remote operation and maintenance system, or maintenance management terminal.

[0035] The above content is only for illustrating the technical concept of the present invention and should not be construed as limiting the scope of protection of the present invention. Any modifications made to the technical solution based on the technical concept proposed in this invention shall fall within the scope of protection of the claims of this invention.
