Description

Technical Field

[0001] This invention relates to the field of power generation tower technology, and in particular to a deployment method for a containerized wind-solar-storage integrated power generation tower. Background Technology

[0002] With the ongoing global energy transition, distributed utilization technologies for clean and renewable energy sources such as wind and solar power have become increasingly mature. Small-scale wind-solar-storage complementary systems, by integrating wind power generation, photovoltaic power generation, and energy storage units, effectively overcome the limitations of the intermittency and volatility of single energy sources, significantly improving the reliability and self-balancing capability of off-grid or microgrid power supply systems. They have shown great potential in special application scenarios such as power supply in remote areas, emergency response, island development, and border outposts.

[0003] To meet the requirements of rapid deployment, strong environmental adaptability, and cost control in the aforementioned scenarios, system integration solutions are gradually evolving from traditional on-site civil construction methods to highly modular, containerized prefabricated structures. This modular container design integrates wind turbine towers, photovoltaic supports, energy storage batteries, power electronic equipment, and other components into standard containers or uses them as structural units, significantly reducing on-site workload, shortening construction cycles, and lowering overall costs.

[0004] However, in the pursuit of rapid deployment and modularity, especially when facing harsh environments such as high altitude, strong winds, and salt spray, existing small-scale wind-solar-storage complementary systems have exposed a series of interconnected and amplified technical bottlenecks, which restrict their long-term reliability, durability, and economy: 1. Structural Integrity and Vibration Transmission Issues: The tower or equipment compartment is constructed by horizontally or vertically splicing multiple container modules. The connection nodes between modules often become weak points in structural rigidity, leading to insufficient system integrity and reduced wind and torsional resistance. More significantly, the operating vibrations of the wind turbine (including mid-to-high frequency vibrations above 10Hz and low-frequency swaying of 0.5-5Hz) are transmitted along this modular structure to the internal precision equipment. Long-term effects can easily lead to loosening of connectors, fatigue damage to circuit boards, and accelerated degradation of battery performance, seriously threatening system safety and lifespan. Existing vibration reduction technologies mostly target single frequency bands, lacking a composite vibration reduction solution that can deeply integrate with the modular tower structure and effectively cover the entire frequency range.

[0005] 2. Challenges in Adaptability to Extreme Cold Environments: In frigid environments, the system faces the dual challenges of rapid performance degradation of the energy storage battery and freezing failure of the liquid working fluid. Existing technologies often adopt a "divide and conquer" strategy, such as adding an independent electric heating device only to the battery pack or adding antifreeze only to the damper. This isolated approach fails to comprehensively utilize the system's internal heat sources and heat demands, resulting in low energy efficiency and the risk of localized failures triggering systemic malfunctions under extreme conditions.

[0006] 3. System rigidity and low asset efficiency: Existing containerized wind, solar and energy storage systems mostly adopt a "fixed binding" integrated design, with energy storage units rigidly connected to specific power generation units. This makes it difficult to quickly decouple and reassemble according to resource changes or scheduling needs, reducing the utilization rate and liquidity of key assets (especially expensive energy storage systems) and failing to meet the needs of future flexible and reconfigurable distributed energy networks.

[0007] Ultimately, the aforementioned problems are not isolated occurrences, but rather a series of chain reactions triggered by the core objective of "rapid modular deployment." Therefore, there is an urgent need for a system-level containerized integrated wind, solar, and energy storage solution that is structurally reliable, vibration-controllable, environmentally adaptable, cost-effective, and enables flexible reuse of energy storage. Summary of the Invention

[0008] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a containerized wind-solar-storage integrated power generation tower, which can systematically resolve the core contradiction between the rapid deployment and long-term reliable operation of modular energy systems, achieving a balance between structural reliability, controllable vibration, wide temperature range adaptability, and efficient energy storage reuse.

[0009] A containerized wind-solar-storage integrated power generation tower according to an embodiment of the present invention includes: A tower structure comprising at least two standard corner-joint container modules vertically spliced ​​together by detachable connectors; A wind power generation unit, wherein the wind power generation unit is installed on the top of the tower structure; An energy storage unit, comprising an energy storage container arranged on the side of the bottom of the tower structure, wherein the energy storage container is a mobile energy storage unit that can be transported independently. A photovoltaic power generation unit, wherein the photovoltaic power generation unit is mounted on the top of the energy storage container and / or the outer surface of the tower structure via a bracket; The tower structure includes a water tank housed within its lowest container module, which serves as both a counterweight and a thermal inertia storage unit. At least one critical reinforcing container module located above the lowest container module houses an internal reinforcing structure and a shock-absorbing device. The power generation tower also includes a liquid circulation temperature control pipeline system connecting the water tank to the energy storage unit, used to regulate the operating temperature of the energy storage unit. Both the wind power generation unit and the photovoltaic power generation unit are electrically connected to the energy storage unit via quick-connect electrical interfaces.

[0010] In some embodiments of the present invention, the internal reinforcing structure is an X-shaped reinforcing rib welded to the four inner walls of the container module. The reinforcing rib is made of Q355B grade steel, and the cross-sectional dimensions of a single rib are not less than 80mm×80mm×8mm. The angle formed between the rib and the inner wall of the container is 45°-60°.

[0011] In some embodiments of the present invention, the shock absorption device includes a shock-absorbing pendant connected between the top of the container module and the bottom of the wind power generation unit base, wherein the damping coefficient of the shock-absorbing pendant is 500-1000 N·s / m.

[0012] In some embodiments of the invention, the shock absorption device includes a liquid wave damper installed inside the critical reinforced container module, the liquid wave damper comprising a sealed container and a high-viscosity damping fluid filled therein.

[0013] In some embodiments of the present invention, the sealed container of the liquid wave damper is rectangular, and the ratio of its bottom length and width to the internal clearance length and width of the container module is between 0.7 and 0.95; the damping fluid is a silicon-based damping fluid with a dynamic viscosity range of 1000-5000 mPa·s.

[0014] In some embodiments of the present invention, the sealed container of the liquid wave damper is empty when it is pre-installed in the critical reinforced container module at the factory, and is pre-installed with a damping fluid filling port and an exhaust valve; after the power generation tower is deployed on site, the damping fluid is filled into the rated volume through the filling port.

[0015] In some embodiments of the present invention, the liquid filled in the water tank is a medium selected according to the expected minimum temperature of the deployment environment: when the expected minimum temperature is above 0°C, clean water is used; when the expected minimum temperature is below or equal to 0°C, antifreeze is selected. The antifreeze is an ethylene glycol-based antifreeze, and its concentration is configured according to the expected minimum ambient temperature: when the expected minimum ambient temperature is -20°C to -30°C, the concentration is 40%-50%; when the expected minimum ambient temperature is -30°C to -40°C, the concentration is 50%-60%.

[0016] In some embodiments of the present invention, the liquid circulation temperature control pipeline system is configured to perform a graded control logic of first preventing freezing and then adjusting the temperature: first, maintaining the pipeline liquid temperature above the freezing point, and then adjusting the temperature according to the equipment temperature of the energy storage unit; the liquid circulation temperature control pipeline system includes a circulation pump, an electric heating element, a temperature control sensor, and a guide pipe connecting the water tank and the energy storage unit, all integrated in the water tank.

[0017] In some embodiments of the present invention, the detachable connector includes a connecting flange welded to the corner fitting of the container and high-strength bolts that penetrate the mating flange. The flange is forged from Q355B grade steel with a thickness ≥20mm, and the number of bolts at each connection node is not less than 8 and is evenly distributed along the circumference of the flange.

[0018] In some embodiments of the present invention, the standard corner frame container module is a container module that meets international standard transportation requirements, including newly manufactured containers or scrap containers that have been repaired to meet structural safety standards; the repaired scrap containers must meet the following requirements: the deformation of the main frame after repair is ≤3‰, the welds are free of cracks, and the adhesion of the anti-corrosion coating reaches level 2 or above in GB / T 9286-1998.

[0019] In some embodiments of the present invention, the water tank is filled with water at a volume not less than 80% of its capacity, and the total weight of the water tank and the liquid inside is more than 1.2 times the total weight of the tower structure, so that the overall overturning stability coefficient of the power generation tower is ≥1.5.

[0020] In some embodiments of the present invention, the wind power generation unit is a vertical axis wind turbine or a horizontal axis wind turbine; when a vertical axis wind turbine is used, it is fixed to the top of the tower by a customized base, and the customized base is provided with no less than 4 reinforcing ribs welded to the main beam of the container; when a horizontal axis wind turbine is used, it is installed by a rotating base, and the load-bearing capacity of the rotating base is not less than 1.5 times the total weight of the wind turbine.

[0021] In some embodiments of the present invention, the technical parameters of the mobile energy storage unit are as follows: energy storage capacity of 150-200kWh, rated voltage of DC500V-800V, rated charge / discharge rate of 0.5C-1C, and cycle life of not less than 3000 cycles (under 80% depth of discharge conditions); it is equipped with a fast charge / discharge connector with a protection level of not less than IP65, supporting DC500V-800V DC output and AC380V three-phase AC output; its bottom is equipped with standard forklift slots and fixing holes adapted to 20-foot or 40-foot container transportation, and its top is equipped with 4 standardized lifting points, with an overall weight not exceeding 30 tons.

[0022] This invention also proposes a deployment method for a containerized wind-solar-storage integrated power generation tower, comprising the following steps: S1. Site preparation: Pour a concrete foundation or place a precast foundation slab at the deployment site; S2. Counterweight and thermal management medium unit setting: hoist the bottom container module to the platform or foundation plate, and inject the selected liquid into the water tank of the bottom container module to more than 80% of its volume according to the expected lowest temperature of the deployment environment, to form a unit with both anti-overturning counterweight and thermal storage functions. S3. Tower assembly: The key reinforced container module and subsequent container modules located above the lowest container module are hoisted in sequence and fixed to the lower modules one by one through detachable connectors to complete the assembly of the tower structure. S4. Vibration damping device activation and wind power generation unit installation: Install vibration damping devices to attenuate tower structure vibration; if the key reinforced container module has a pre-installed empty liquid undulation damper sealed container, fill it with damping fluid; then, install the wind power generation unit on the top of the assembled tower structure. S5. Energy storage and temperature control deployment: Deploy a mobile energy storage unit on the side of the bottom of the tower structure, connect the wind power generation unit to the quick-connect electrical interface of the mobile energy storage unit, and connect the liquid circulation temperature control pipeline system to the mobile energy storage unit; S6. Photovoltaic power generation unit installation: Install a photovoltaic power generation unit on the top of the mobile energy storage unit and / or on the outer surface of the tower structure; S7. System Debugging: Complete all electrical connections and debug them to bring the system into operation. All functional modules are prefabricated in the factory, requiring only standardized splicing and connection on site. The total deployment cycle for steps S2 to S7 is 3-5 days.

[0023] Compared with existing technologies, the containerized wind-solar-storage integrated power generation tower and deployment method provided by this invention, through system-level collaborative design, have the following beneficial effects: First, by deeply coupling the four major functions of structural reinforcement, vibration control, environmental temperature control and energy storage reuse, the interconnected technical bottlenecks caused by modular rapid deployment, such as insufficient structural integrity, vibration transmission, poor adaptability to extreme cold environments and low asset utilization, are fundamentally solved, achieving non-obvious integrated innovation.

[0024] Secondly, the use of high-strength flange connections and internal X-shaped reinforcing ribs significantly improves the overall rigidity and stability of the modular tower, and calculations have verified that it can meet the requirements of a level 12 typhoon and an 8-degree seismic fortification.

[0025] Third, the unique rigid-flexible coupling vibration damping system offers two targeted solutions: shock-absorbing pendants and liquid wave dampers, which can be used individually or in combination. When used in combination, by suppressing high-frequency vibrations and low-frequency swaying respectively, the overall vibration attenuation rate is increased by 15%-20% compared to a single solution, effectively ensuring the long-term stable operation of the tower and its internal equipment under complex wind conditions.

[0026] Fourth, the bottom water tank serves as both an anti-tipping counterweight and a thermal inertia storage unit. Through an intelligent graded control strategy of first preventing freezing and then regulating temperature, the operating temperature of the energy storage battery is maintained in the high-efficiency range of 5-15℃ while ensuring that the system does not freeze under extreme low temperatures. This increases its low-temperature cycle life by more than 20%, achieving a balance between safety and performance optimization.

[0027] Fifth, the energy storage unit adopts a standardized container design and becomes a "detachable energy hub" through a quick-connect interface, supporting cyclical distribution and use. This significantly increases the annual utilization rate of energy storage equipment from 25%-30% in traditional fixed solutions to over 65%, greatly improving asset utilization efficiency and project economics.

[0028] Sixth, the system, through media selection and intelligent temperature control, can ensure reliable operation within a wide temperature range of -40℃ to 45℃. Using repaired and compliant scrap shipping containers as tower modules reduces material costs and on-site construction waste, embodying the green concept of resource recycling.

[0029] Seventh, all functional modules are prefabricated in the factory, requiring only standardized splicing and connection on site. The overall deployment cycle can be shortened to 3-5 days, making it particularly suitable for various scenarios such as emergency power supply, power supply in remote areas, distributed energy stations, and flexible power distribution in industrial parks.

[0033] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0034] The following is for reference. Figures 1-10 A containerized wind-solar-storage integrated power generation tower 100 according to an embodiment of the present invention is described, comprising a tower structure 10, a wind power generation unit 20, an energy storage unit 30, and a photovoltaic power generation unit 40. The tower structure 10 includes at least two standard corner-joint structure container modules vertically spliced ​​together by detachable connectors; the wind power generation unit 20 is installed on the top of the tower structure 10 for capturing wind energy and converting it into electrical energy; the energy storage unit 30 includes an energy storage container 31 arranged on the bottom side of the tower structure 10, the energy storage container 31 being a mobile energy storage unit that can be independently transported; the photovoltaic power generation unit 40 is installed on the top of the energy storage container 31 and / or the outer surface of the tower structure via a bracket for capturing solar energy and converting it into electrical energy; wherein, the bottom of the tower structure 10 is equipped with... The container module 11 is equipped with a water tank 90, which constitutes a unit that has both counterweight function and thermal inertia storage function; in the tower structure 10, at least one key reinforced container module 12 located above the bottommost container module 11 is equipped with an internal reinforcing structure 50 and a shock absorption device 60; the power generation tower 100 also includes a liquid circulation temperature control pipeline system 70 connecting the water tank and the energy storage unit 30, which is used to regulate the operating temperature of the energy storage unit 30; the wind power generation unit 20 and the photovoltaic power generation unit 40 are both electrically connected to the energy storage unit 30 through a quick-connect electrical interface.

[0035] For example, the tower structure 10 can be constructed by vertically splicing two or three standard corner-structure container modules. Two adjacent container modules are connected and fixed together by detachable connectors 80. These detachable connectors 80 use flange bolt connections, including connecting flanges 81 welded to the container corners and 10.9-grade high-strength bolts 82 penetrating the flanges. Each connection node has at least eight bolts 82, evenly distributed and tightened along the circumference of the flanges 81. The flanges 82 are forged from Q355B grade steel with a thickness ≥20mm. This method of connection between container modules ensures connection strength. The wind power generation unit 20 is installed at the top of the tower structure 10 (i.e., the top of the uppermost container module) to capture wind energy and convert it into electrical energy, which is then transmitted to the energy storage unit 30.

[0036] The energy storage unit 30 may include two energy storage containers 31 symmetrically arranged on the bottom side of the tower structure 10. Each energy storage container 31 is a mobile energy storage unit that can be transported independently, featuring a fast-charging and discharging interface, a standardized transport adaptability structure, and an independent battery management system. It connects to the power generation system via a quick-connect electrical interface, allowing the energy storage unit to switch between a charging connected state and a transport disconnected state. For example, the energy storage unit can be fully charged and disconnected from the system, delivered to scenarios such as enterprise parks to provide independent power, and then returned to recharge after use, forming a cycle. The quick-connect electrical interface is a quick-plug DC connector conforming to the GB / T34872-2017 standard, with a protection level of not less than IP65, supporting safe connection and disconnection within 10 minutes. The top of each energy storage container 31 and / or the outer surface of the tower structure may be equipped with photovoltaic power generation units 40 for capturing light energy and converting it into electrical energy. The photovoltaic power generation units 40 can be fixed to the energy storage container 31 by brackets. To maximize solar energy capture efficiency, the bracket's tilt angle is adjustable within the range of 15°-35°. It can be manually or automatically adjusted to the optimal incident angle based on the latitude and season of the deployment site, thereby improving the power generation benefits throughout the entire life cycle.

[0037] The lowest container module 11 in the tower structure 10 houses a water tank 90, which serves as both a counterweight and a thermal inertia storage unit. Firstly, the liquid injected into the tank provides anti-overturning counterweight for the entire tower structure 10. When the water level is at least 80% of the tank's volume and the total weight of the tank and its contents is more than 1.2 times the total weight of the tower structure 10, the overall anti-overturning stability coefficient of the power generation tower can be ≥1.5. Secondly, the large mass of liquid in the tank constitutes a highly efficient thermal inertia storage unit, which can be connected to the energy storage unit 30 via a liquid circulation temperature control pipeline system 70, forming a closed-loop heat exchange circuit to regulate the operating temperature of the energy storage unit 30. The key reinforcing container module 12 in the tower structure 10 houses an internal reinforcing structure 50 and a vibration damping device 60. These internal reinforcing structures and vibration damping devices are synergistically designed to address the vibration mode characteristics of the entire tower structure, forming a rigid-flexible coupled vibration-resistant system.

[0038] It should be noted that the aforementioned standard corner-fit structure container modules can use container modules that meet international standard transportation requirements, including newly manufactured containers or repaired used containers that meet structural safety standards. Repaired used containers (40-foot or 20-foot) must meet the following requirements: the deformation of the repaired main frame ≤3‰, no cracks in the welds, anti-corrosion coating adhesion reaching level 2 or above in GB / T 9286-1998, and rust removal grade not lower than Sa2.5. The cables 32 between each power generation unit and the energy storage unit 30 are laid through a pre-installed sealed PVC cable channel (diameter ≥80mm) inside the tower structure. The sealed PVC cable channel has a built-in fireproof rock wool filling layer, and both ends are sealed to the container module wall using silicone rubber seals. The fire resistance rating meets the Class C requirements in GB 20286-2006 to prevent cable aging or short circuits under extreme temperature and humidity conditions.

[0039] Understandably, the wind power generation unit 20 captures wind energy, and the photovoltaic power generation unit 40 captures solar energy. Through a rapid electrical connection interface, they transmit the electrical energy to the mobile energy storage unit at the bottom side for storage and dispatch, achieving a natural complementarity between wind and solar power generation in time and space. The water tank within the lowest container module 11 of the tower structure 10 serves two purposes: firstly, as a ballast counterweight, significantly improving the overall tower's anti-overturning stability through its mass; and secondly, as a thermal inertia storage unit, providing stable thermal management for the energy storage unit 30 in cold environments through a liquid circulation temperature control pipeline system 70. Simultaneously, the vibration damping device 60 located within the critical reinforced container module 12 works in conjunction with the internal reinforcing structure 50 to form a rigid-flexible coupling system, effectively suppressing broadband vibrations of the tower structure 10 caused by wind turbine operation and wind loads, ensuring the structural integrity and operational reliability of the modular spliced ​​tower under long-term dynamic loads. The entire system, through rapid deployment via modular splicing, with deep integration and collaborative work of various functional units, ultimately achieves a complete closed loop from renewable energy capture and storage to stable energy supply.

[0040] In some embodiments of the present invention, reference is made to... Figures 1 to 8 As shown, the internal reinforcing structure 50 can be X-shaped reinforcing ribs welded to the four inner walls of the container module. The reinforcing ribs are made of Q355B grade steel, with a single cross-sectional dimension of not less than 80mm×80mm×8mm, and the angle formed between them and the inner wall of the container is 45°-60°. For example, the angle between each reinforcing rib and the inner wall of the container is uniform, and both ends of each reinforcing rib are fully welded to the container's crossbeams and longitudinal beams, with a weld length ≥200mm.

[0041] Understandably, the aforementioned internal reinforcement structure creates a highly efficient triangular support system in terms of mechanical performance. This significantly enhances the overall stiffness and deformation resistance of the container module, effectively distributing and bearing the complex stresses generated by wind turbine operation and wind loads. In particular, it suppresses local buckling and stress concentration at module joints, thus ensuring the integrity and stability of the tower structure assembled from multiple independent modules. Regarding vibration control, this high-rigidity internal frame works in synergy with the external casing, altering the structure's natural mode shape and increasing its natural frequency. This provides a superior foundation for the accompanying vibration damping devices (such as liquid wave dampers). Together, they form a rigid-flexible coupled vibration-resistant system, synergistically attenuating the tower's broadband vibrations. From an engineering perspective, the internal reinforcement structure is prefabricated and welded in the factory, ensuring construction quality and precision without occupying valuable transportation and external installation space. This achieves a seamless integration of structural reinforcement with modular and rapid deployment concepts. Furthermore, the use of standardized Q355B steel and standardized dimensional design ensures material availability, economic rationality, and predictability of structural performance, thereby enhancing the reliability and engineering value of the entire power generation tower system.

[0042] In some embodiments of the present invention, reference is made to... Figures 1 to 8 As shown, the shock absorption device 60 may include a shock-absorbing pendant 61 connected between the top of the container module and the bottom of the wind power generation unit base, and the damping coefficient of the shock-absorbing pendant 61 is 500-1000 N·s / m.

[0043] Understandably, the vibration damping pendant 61 can effectively attenuate and isolate mid-to-high frequency vibrations (typically >10Hz) generated by the rotation of wind turbine blades and the operation of gearboxes. Through its precisely tuned damping characteristics, the vibration damping pendant 61 can significantly absorb and dissipate this vibrational energy, preventing it from being directly transmitted to the tower structure 10 below. This not only significantly reduces the fatigue load on the tower structure 10 and its internal equipment, extending the service life of key mechanical and electrical components, but more importantly, it lays the foundation for the stability of the entire tower structure 10 by cutting off the main transmission path of high-frequency vibrations, bringing highly targeted dynamic performance optimization to the system.

[0044] In some embodiments of the present invention, reference is made to... Figures 1 to 8 As shown, the shock absorption device 60 includes a liquid wave damper 62 installed inside the critical reinforced container module 12. The liquid wave damper 62 includes a sealed container and a high-viscosity damping fluid filled therein. For example, the sealed container of the liquid wave damper 62 can be pre-installed in the critical reinforced container module 12 at the factory, and is in an empty state during installation. The sealed container is pre-installed with a damping fluid filling port and an exhaust valve. After the power tower is deployed on site, the damping fluid is filled to the rated volume through the filling port. The entire sealed container may include a box 621 with an open top, a cover plate 622 installed on the top of the box 621, and a flow-blocking element 623 placed inside the box 621. The flow-blocking element 623 can generate a certain resistance to the liquid inside the box 621, preventing it from flowing rapidly and tilting, thereby improving its shock absorption effect.

[0045] Understandably, the liquid undulation damper 62 installed inside the critical reinforced container module 12, through the inertial undulation and viscous dissipation effect of the high-viscosity damping fluid within its sealed container, can provide good low-frequency vibration control for the core structure. Specifically, the liquid undulation damper 62 can efficiently absorb and convert the 0.5-5Hz low-frequency large-amplitude swaying caused by the overall bending mode of the tower excited by strong winds and turbulence into the internal energy and thermal energy of the liquid, thereby significantly suppressing the displacement of the tower top and improving the stability and safety of the structure under severe wind conditions. Its modular built-in design does not occupy external space and is rigidly integrated with the container structure, ensuring damping efficiency; at the same time, the high-viscosity damping fluid provides stable performance over a wide temperature range.

[0046] In view of this, when a composite vibration reduction structure consisting of a shock absorber 61 and a liquid undulation damper 62 is adopted, a more systematic and full-frequency vibration control solution can be provided for the entire tower structure 10. Specifically, the shock absorber 61, with a damping coefficient of 500-1000 N·s / m, effectively attenuates and isolates the mid-to-high frequency vibrations above 10Hz generated by the rotating parts of the wind turbine, effectively protecting the tower structure and internal equipment from high-frequency fatigue damage, thanks to its precisely tuned damping characteristics. At the same time, the liquid undulation damper 62, installed inside the critical reinforced container module 12, focuses on suppressing the low-frequency large-amplitude swaying of 0.5-5Hz generated by the overall bending mode of the tower excited by strong winds and turbulence through the inertial undulation and viscous dissipation of the high-viscosity damping fluid in its sealed container, significantly improving the tower's anti-sway stability and safety under severe wind conditions. The two components complement and synergize precisely in terms of spatial layout and frequency response: the shock-absorbing pendant 61 cuts off the high-frequency transmission path from the source (top); the liquid wave damper 62 acts at key locations on the tower (middle or lower part) to absorb low-frequency overall energy. This composite vibration reduction design of "high and low frequency synergy and rigid-flexible coupling" not only targets the two most prominent vibration hazards of modular towers, but also achieves an overall vibration reduction effect of "1+1>2" through system integration, which greatly improves the overall vibration attenuation rate of the tower structure and fundamentally ensures the structural integrity, operational stability, and equipment reliability of the power generation tower composed of quick-assembly and disassembly modules under long-term complex dynamic loads.

[0047] In some embodiments of the present invention, reference is made to... Figures 1 to 8 As shown, the sealed container of the liquid wave damper 62 is rectangular, and the ratio of its bottom length and width to the internal clearance length and width of the container module is between 0.7 and 0.95; the damping fluid is a silicon-based damping fluid with a dynamic viscosity range of 1000-5000 mPa·s.

[0048] Specifically, the sealed container of the liquid undulation damper 62 is designed as a rectangle with a bottom dimension to internal container clearance dimension ratio between 0.7 and 0.95, and filled with a silicon-based damping fluid with a dynamic viscosity of 1000-5000 mPa·s. This structural design achieves an optimal balance between engineering efficiency and space utilization. The rectangular structure maximizes the use of the rectangular cross-sectional space inside the container module, allowing it to accommodate a larger volume of damping fluid within a limited volume, thereby obtaining a more significant liquid inertia and undulation effect. The dimension ratio of 0.7 to 0.95 ensures that the damping fluid has sufficient flow space to fully dissipate energy during sloshing, while avoiding liquid surface breakage failure due to an excessively small container or installation interference due to an excessively large container. The selection of a silicon-based damping fluid within this viscosity range ensures sufficient viscous shear force for efficient energy dissipation under low-frequency excitation, while maintaining stable rheological properties over a wide temperature range (especially in low-temperature environments), preventing freezing or sudden performance changes. The precisely matched geometric and physical parameters together enable the damper to produce a highly targeted and reliable suppression effect on the specific low-frequency swaying modes (0.5-5Hz) of the tower, making it an indispensable key component in the rigid-flexible coupling vibration-damping system of the modular tower.

[0049] In some embodiments of the present invention, reference is made to... Figures 1 to 8 As shown, the liquid filled in the water tank is a medium selected based on the expected minimum temperature of the deployment environment: when the expected minimum temperature is above 0°C, clean water is used; when the expected minimum temperature is below or equal to 0°C, antifreeze is selected.

[0050] Understandably, the strategy of intelligently selecting the water tank filling medium based on the expected lowest temperature of the deployment environment (using clean water above 0°C and antifreeze at 0°C and below) achieves a balance between environmental adaptability, functional reliability, and economy. Its primary function is to ensure the system's core safety under extreme cold conditions: by using antifreeze, the risk of complete failure of the liquid circulation temperature control pipeline system due to liquid freezing is fundamentally prevented, ensuring the continuous operation of the temperature control system. Simultaneously, this selection strategy gives the system strong regional adaptability, allowing it to be deployed in a wide range of areas from temperate to frigid zones without hardware modifications. Using clean water in non-cold environments avoids unnecessary antifreeze costs, reduces deployment and maintenance expenses, and reflects the engineering economy of on-demand configuration. Furthermore, neither clean water nor antifreeze compromises its core function as a counterweight and mass block, retaining its high heat capacity characteristics and providing a stable thermal inertia buffer for the thermal management of the energy storage battery.

[0051] In some embodiments of the present invention, the antifreeze can be an ethylene glycol-based antifreeze, the concentration of which is configured according to the expected minimum ambient temperature: when the expected minimum ambient temperature is -20°C to -30°C, the concentration is 40%-50%; when the expected minimum ambient temperature is -30°C to -40°C, the concentration is 50%-60%.

[0052] Understandably, using glycol-based antifreeze with concentrations that can be graded according to the expected lowest ambient temperature provides the system with precisely matched, safe, and reliable all-weather antifreeze protection. For environments ranging from -20°C to -30°C, a concentration of 40%-50% ensures a significantly lower freezing point than the ambient temperature, providing sufficient safety margin while maintaining good fluidity and heat exchange efficiency. For even colder environments of -30°C to -40°C, increasing the concentration to 50%-60% further significantly lowers the freezing point, resisting extreme cold and ensuring that the liquid circulation pipeline will never freeze at extreme low temperatures. This method of finely configuring the concentration according to temperature zones avoids the performance waste or insufficient protection problems caused by a single fixed concentration: too low a concentration may fail at extreme temperatures, while too high a concentration will increase costs, reduce specific heat capacity, and may exacerbate the pumping burden. This configuration not only achieves absolute reliability of the antifreeze function but also optimizes the system's operating energy efficiency and economy.

[0053] In some embodiments of the present invention, the liquid circulation temperature control pipeline system 70 is configured to execute a graded control logic of first preventing freezing and then adjusting temperature: first, maintaining the pipeline liquid temperature above the freezing point, and then adjusting the temperature according to the equipment temperature of the energy storage unit 30. For example, the liquid circulation temperature control pipeline system 70 may include a circulation pump, an electric heating element, a temperature control sensor, and a guide pipe connecting the water tank and the energy storage unit 30, all integrated within the water tank; multiple temperature control sensors are used to monitor the ambient temperature, the liquid temperature, and the equipment temperature of the energy storage unit. The entire system executes a coordinated control strategy: first, monitoring and maintaining the liquid temperature in the water tank above its freezing point, and then controlling the operating state of the circulation pump and the electric heating element according to the equipment temperature of the energy storage unit 30, so as to maintain the core operating temperature of the energy storage unit within a preset optimized range.

[0054] Specifically, firstly, before deployment, the liquid (clean water or antifreeze) to be filled in the water tank must be selected based on the extreme minimum temperature data from the site's meteorological data. This is the foundation for the system's winter operation. Secondly, the liquid circulation temperature control pipeline system adopts an intelligent hierarchical control strategy of prioritizing antifreeze before temperature adjustment. Multiple temperature sensors monitor the ambient temperature, water tank liquid temperature, and energy storage unit equipment temperature in real time, executing management logic with clearly defined priorities. During operation, the system first ensures that the pipeline liquid never freezes (active antifreeze): when the liquid temperature approaches its freezing point (with a preset safety margin of 3-5℃), the electric heating element in the water tank is immediately activated for preheating, ensuring that its temperature remains above the freezing point. This absolutely avoids the risk of blockage in the circulation pipeline due to liquid solidification. This highest-priority measure guarantees the physical unobstructed flow and functional continuity of the entire thermal circulation loop in extremely cold environments. After ensuring this prerequisite, the system performs fine-tuned temperature control based on the actual temperature of the energy storage unit 30: when the equipment temperature is below the optimal operating range, the circulation pump is started to use the heat stored in the high heat capacity liquid in the water tank to keep or raise the temperature of the equipment; when the equipment temperature is too high, the circulation pump is started to dissipate heat and cool the equipment. Its ultimate goal is to precisely maintain the core operating temperature of the lithium battery within the optimized range of 5-15℃.

[0055] Understandably, an active antifreeze mechanism can fundamentally prevent system functional failures caused by liquid freezing, ensuring survivability and high reliability under extreme low temperatures. By maintaining the battery operating temperature within a narrow optimized range, its charge-discharge efficiency can be increased to over 95%, and its lifespan degradation can be significantly slowed down. According to experimental and industry data, its cycle life can be increased by approximately 20% compared to operating below 0°C or at high temperatures. Reusing the counterweight water tank as a thermal inertia storage unit eliminates the need for a separate and complex heating system, reducing costs and energy consumption. Its hierarchical logic follows the engineering principle of prioritizing uninterrupted operation over performance, and through intelligent collaborative management, it ultimately ensures safe, reliable, and efficient operation across a wide temperature range from frigid to ambient temperatures.

[0056] In some embodiments of the present invention, reference is made to... Figure 1 and Figure 2 As shown, the wind power generation unit is a vertical axis wind turbine or a horizontal axis wind turbine; such as Figure 1 As shown, when a vertical axis wind turbine is used, it is fixed to the top of the tower via a customized base. The customized base is equipped with no fewer than four reinforcing ribs welded to the main beam of the container. Figure 2 As shown, when a horizontal axis wind turbine is used, it is installed on a rotating base, and the load-bearing capacity of the rotating base is not less than 1.5 times the total weight of the wind turbine.

[0057] In some embodiments of the present invention, the technical parameters of the mobile energy storage unit meet the following requirements: energy storage capacity of 150-200kWh, rated voltage of DC500V-800V, rated charge / discharge rate of 0.5C-1C, and cycle life of not less than 3000 cycles (under 80% depth of discharge conditions); it is equipped with a fast charge / discharge connector with a protection level of not less than IP65, supporting DC500V-800V DC output and AC380V three-phase AC output; its bottom is equipped with standard forklift slots and fixing holes adapted to 20-foot or 40-foot container transportation, and its top is equipped with 4 standardized lifting points, with an overall weight not exceeding 30 tons.

[0058] To ensure the structural reliability of this power generation tower, detailed mechanical calculations and simulations were performed on a typical configuration (total tower height approximately 30.442 meters, consisting of two upright 40-foot containers (each 12.192 meters high), one upright 20-foot containerized power generation module (6.058 meters high), cross-sectional dimensions 2.438 meters × 2.591 meters, corner columns made of SPA-H weathering steel, 140mm × 140mm × 6mm, water tank filling volume approximately 61.84 m³).

[0059] 1) Determination of design loads: Wind load: Designed for a Category 12 typhoon, with a basic wind speed of V0 = 32.7 m / s. According to the "Code for Design of Building Structures" (GB 50009-2012), considering the wind pressure height variation coefficient, wind load shape coefficient, and gust coefficient, the total standard value of the wind load F_k acting on the tower and wind power generation unit (sweeped area calculated as 4m²) is approximately 208 kN.

[0060] Overturning moment: The standard value of the overturning moment M_k generated by the wind load acting on the height of the tower centroid is calculated to be approximately 3345 kN·m.

[0061] Seismic action: calculated based on seismic fortification intensity of 8 degrees (design basic seismic acceleration value of 0.20g).

[0062] 2) Strength and stability verification: Strength verification: Under the combined action of the aforementioned wind load, structural self-weight, and equipment self-weight, a combined stress calculation was performed on the bottom of the tower (the most unfavorable section). The results show that the maximum combined stress value is approximately 260 MPa, which is lower than the yield strength of the main steel of the tower (SPA-H, yield strength f_y ≥ 345 MPa), and the strength meets the safety requirements.

[0063] Overturning stability verification: The overall overturning stability is guaranteed by the bottom foundation structure. The foundation design needs to determine the bearing capacity of the foundation based on the on-site geological survey report, and calculate and determine the foundation dimensions based on wind load and seismic action (such as using a concrete cap or pile foundation) to ensure that the overturning stability coefficient is not less than 1.5 under the most unfavorable load combination. The bottom water tank and liquid counterweight provide important protection for this.

[0064] Seismic verification: The cross-sectional bearing capacity was verified under frequent earthquakes according to the code. The calculation shows that, under the control of the design wind load of this system, the internal forces generated by the seismic action are less than those generated by the wind load, and the structural safety is controlled by the wind load condition.

[0065] 3) Vibration resistance evaluation: Through finite element dynamics simulation analysis, after applying the rigid-flexible coupling anti-vibration system composed of the internal reinforcing structure 50 and the damping device 60 of this invention, the vibration amplitude of the tower structure 10 at its key parts (such as the top of the key reinforced container module and the connection nodes) can be reduced by more than 30% under rated wind speed operating conditions. In particular, when only the liquid wave damper 62 is selected, or when the shock absorber 61 and the liquid wave damper 62 are used in combination, the dynamic response at the first natural frequency of the tower can be attenuated by more than 40%, effectively suppressing the risk of resonance. Compared with a single preferred damping scheme, the combined scheme can achieve an additional 15%-20% improvement in vibration attenuation rate.

[0066] The above calculation and verification results show that the containerized wind-solar-storage integrated power generation tower 100 of the present invention can achieve stable operation in extreme environments such as a level 12 typhoon and an 8-degree earthquake.

[0067] In summary, this invention constructs a deeply collaborative innovation system centered on a modular container tower: the tower is vertically spliced ​​from standard container modules using high-strength flanges, with X-shaped reinforcing ribs forming a rigid frame in key load-bearing sections; simultaneously, it innovatively addresses the vibration problem of the modular tower by proposing a rigid-flexible coupling vibration-damping system, using shock-absorbing pendants to attenuate high-frequency vibrations and liquid wave dampers to suppress low-frequency swaying, the combined use of which can improve the overall vibration reduction efficiency by 15%-20%. Based on this, the system creatively designs a counterweight-temperature control reuse function, utilizing a large-capacity water tank at the bottom to simultaneously meet the requirements for anti-tipping counterweight and thermal management in extreme environments, and using an intelligent control strategy of first preventing freezing and then regulating temperature to ensure efficient operation of the energy storage battery within a wide temperature range of -40℃ to 45℃. The energy storage unit adopts a standardized container design and is equipped with a quick-connect interface, realizing a detachable energy hub function, increasing the utilization rate of energy storage assets from 25%-30% in traditional solutions to over 65%. This invention, through system-level function reuse and collaborative design, enables rapid deployment in 3-5 days while comprehensively solving interrelated technical challenges such as vibration suppression of modular structures, adaptation to extreme environments, and asset recycling, thus possessing high engineering practicality and economic efficiency.

[0068] This invention also discloses a deployment method for a containerized wind-solar-storage integrated power generation tower, comprising the following steps: S1. Site preparation: Pour a concrete foundation or place a precast foundation slab at the deployment site; S2. Counterweight and thermal management medium unit setting: hoist the bottom container module to the platform or foundation plate, and inject the selected liquid into the water tank of the bottom container module to more than 80% of its volume according to the expected lowest temperature of the deployment environment, forming a unit with both anti-overturning counterweight and thermal storage functions. S3. Tower assembly: The key reinforced container module and subsequent container modules located above the bottommost container module are hoisted in sequence and fixed to the modules below level by level through detachable connectors to complete the assembly of the tower structure; S4. Vibration damping device activation and wind power generation unit installation: Install vibration damping devices to attenuate tower structure vibration; if there is an empty liquid undulation damper sealed container pre-installed in the key reinforcement container module, fill it with damping fluid; then, install the wind power generation unit on the top of the assembled tower structure. S5. Energy Storage and Temperature Control Deployment: Deploy a mobile energy storage unit on the side of the bottom of the tower structure, connect the wind power generation unit to the mobile energy storage unit via a quick-connect electrical interface, and connect the liquid circulation temperature control pipeline system to the mobile energy storage unit. S6. Photovoltaic power generation unit installation: Install photovoltaic power generation units on the top of the mobile energy storage unit and / or on the outer surface of the tower structure; S7. System Debugging: Complete all electrical connections and debug them to bring the system into operation. The total deployment cycle for steps S2 to S7 is 3-5 days.

[0069] Understandably, this deployment method first completes the basic preparation, providing stable support for the superstructure. Then, the lowest module is hoisted and injected with liquid; this crucial step simultaneously accomplishes two core functions: first, by using a large-mass liquid counterweight, it establishes the tower's anti-overturning stability from the initial stage (anti-overturning stability coefficient ≥1.5); second, it pre-establishes a thermal inertia storage unit for subsequent thermal management. Next, the tower modules are vertically assembled like building blocks, with pre-installed X-shaped reinforcing ribs and high-strength connectors forming a rigid main frame. After the structure is formed, the vibration damping device is activated: if liquid dampers are used, damping fluid is injected to give them energy dissipation capabilities. This is done simultaneously with the installation of the wind power generation unit, ensuring that vibration control and power generation are coordinated. Then, the mobile energy storage unit, serving as the energy hub, is deployed and quickly connected to electrical and temperature control pipelines, forming a complete closed loop of generation-storage-thermal management. Finally, photovoltaic modules are installed on top of the already positioned energy storage unit and on the tower surface, maximizing space utilization to achieve wind-solar complementarity. Finally, a system-wide commissioning is conducted to ensure that all subsystems work together to achieve optimal operating conditions. The core principle of this method lies in decomposing and solidifying complex technical requirements such as structural safety, vibration control, and environmental adaptability into rapid, linear on-site installation actions through pre-defined module functions and strict procedural logic.

[0070] Example 1: Basic configuration using vibration reduction scheme A Scenario: A typical environment with the lowest temperature above 0°C, taking the typical simplified model in the structural verification description (i.e., the tower is composed of two 40-foot container modules vertically spliced ​​together) as an example.

[0071] 1. Structural Preparation: Select two 40-foot container modules. The upper module is designated as the critical reinforced container module, and X-shaped reinforcing ribs and shock-absorbing pendant connectors are welded inside it. The bottom module is converted into a water tank.

[0072] 2. On-site deployment: After the foundation construction is completed, hoist and vertically assemble the two container modules. Install the shock-absorbing pendants and wind turbine. Fill the water tank with clean water to 85% of its volume. This step simultaneously completes the structural counterweight (the total weight of the water tank and clean water is 1.3 times the total weight of the tower structure, and the overturning stability coefficient reaches 1.6) and the storage of thermal management media.

[0073] 3. System Integration: Two mobile energy storage containers are deployed next to the tower, and the temperature control piping and electrical wiring are connected via quick-connect DC connectors conforming to GB / T 34872-2017. The connection takes 8 minutes. Photovoltaic modules are installed on the top of the energy storage containers, and the bracket tilt angle is adjusted to 25° to adapt to local sunlight.

[0074] 4. Results: The entire system was deployed within 3 days. The X-shaped reinforcing ribs and shock-absorbing pendants worked together to effectively reduce tower vibration during wind turbine operation, with vibration amplitude in key areas reduced by 32%. The water tank provided stable counterweight and, through a temperature control system, provided insulation for the energy storage battery when the ambient temperature was low. The system operated stably, and the energy storage unit's charge and discharge efficiency remained above 95%.

[0075] Example 2: Enhanced configuration using shock absorption scheme B Scenario: Coastal areas, grasslands, and other regions with frequent strong winds and severe winters (minimum temperature -25℃).

[0076] 1. Structural Preparation: Two 40-foot container modules were selected. An empty rectangular liquid wave damper sealed container was pre-fixed in the center of the base plate above the key reinforcing container module in tower structure 10. The container's dimensions were close to the container's internal cross-section (bottom area accounting for 85%), and a filling port was provided. The lowest water tank was pre-filled with 45% ethylene glycol antifreeze, based on the expected minimum temperature of -25°C, to 82% of its volume. The total weight of the water tank and antifreeze was 1.25 times the total weight of the tower structure, achieving an overturning stability coefficient of 1.55.

[0077] 2. On-site deployment: After the tower structure 10 is hoisted and assembled, inject silicon-based damping fluid with a dynamic viscosity of 3000 mPa·s into the container to 90% of its volume through the filling port. Install the horizontal axis wind turbine, with the rotating base having a load-bearing capacity of 1.6 times the total weight of the turbine. Connect all systems.

[0078] 3. Results: The liquid wave damper, in conjunction with the X-shaped reinforcing ribs, effectively dissipates the low-frequency swaying energy of the tower caused by strong winds, reducing the vibration amplitude of key components by 41%. Under the "active antifreeze" logic control of the temperature control system, the antifreeze in the water tank is consistently maintained above -5℃, without freezing. Furthermore, the "equipment temperature control" logic stabilizes the core operating temperature of the energy storage unit at 8-12℃, increasing cycle life by 23% compared to solutions without temperature control. The system exhibits extremely high stability in harsh environments with strong winds and extreme cold.

[0079] Example 3: Mobile Energy Storage and Distribution Application The power generation tower of any of the above embodiments can be used as the charging mother station.

[0080] 1. Charging: The mobile energy storage container is connected to the power generation tower via a quick-connect DC connector to receive wind-solar hybrid charging. It takes about 8 hours to fully charge 150kWh of electricity.

[0081] 2. Delivery: After being fully charged, disconnect the electrical and piping connections, which takes 10 minutes; then, using its own standardized forklift slots and lifting points, it can be transported by trailer to an industrial park 10 kilometers away.

[0082] 3. Power supply: Through its external IP65-rated fast interface, it provides emergency production power to the park for 2 days, with a stable power supply of 50kW.

[0083] 4. Recharge: After the power is depleted, the energy is transported back to the power tower for recharging, completing a reuse cycle. This mode realizes the spatial and temporal transfer of electrical energy and the recycling of energy storage assets. Its feasibility is rooted in the stable and reliable charging guarantee provided by the power tower system. Calculations show that the energy storage unit can achieve an average annual utilization rate of 72% in typical scenarios, which is significantly improved compared to traditional fixed solutions, demonstrating the advantages of the system-level integrated innovation of this invention in terms of operation mode.

[0084] This invention's deployment method, through a close integration of deep factory prefabrication (such as reinforced structures and pre-installed damper containers) and standardized on-site operations, compresses a project that traditionally takes weeks to complete within 3-5 days. Furthermore, the output of each step is clearly defined (such as achieving the required counterweight and ensuring secure connections), significantly reducing the uncertainty of on-site construction. The entire method embodies the collaborative design philosophy of the invention. For example, step S2 (liquid injection counterweight) is a prerequisite for step S5 (temperature-controlled connection), ensuring that the thermal management system has a usable heat source; step S4 (activating vibration damping) follows step S3 (structural splicing), ensuring vibration suppression of the existing structure. This process logic ensures that the final system highly matches the design performance, achieving overall stability and a long equipment lifespan. The quick-connect interface (S5) and standardized deployment process allow energy storage units to be safely and efficiently connected to or disconnected from the main body of the power generation tower, providing a repeatable and reliable physical basis for a charging-disconnection-return asset recycling model, thereby increasing the utilization rate of energy storage equipment to over 65%. This deployment method incorporates an environmental adaptability selection (the injection medium is selected based on the temperature in S2), allowing the same process to be adapted to different environments from temperate to frigid (-40℃) through fine-tuning (such as using antifreeze), thus expanding its application range.

[0085] In conclusion, this deployment method is not only a description of the installation sequence, but also a key guarantee for the high-quality, high-efficiency, and high-reliability reproduction of the system-level innovation in the invention in engineering practice. It is an important component for improving product competitiveness and user experience.
