Description

Technical Field

[0001] This utility model relates to the technical field of vanadium redox flow battery equipment, specifically to an integrated skid-mounted, leak-proof container for vanadium redox flow batteries. Background Technology

[0002] Vanadium redox flow batteries (VRBs), as energy storage devices with high safety, long cycle life, and flexible capacity expansion capabilities, have been widely used in new energy power generation and storage, and grid peak shaving. However, traditional VRB equipment has significant structural design flaws. The various functional components (such as the stack, electrolyte tank, piping system, and control system) are mostly distributed, lacking a unified integrated design. In practical applications, these dispersed components require complex on-site installation and connection to form a complete working system, which not only increases the difficulty and time of installation and construction but also raises the risk of leakage due to the excessive number of connection points between components. More critically, traditional equipment lacks effective leak-proof mechanisms and integrated protective structures. The electrolyte in vanadium redox flow batteries is corrosive; leaks not only cause battery system shutdowns and economic losses but also pollute the surrounding environment and pose safety hazards. Current technologies lack effective, real-time leak monitoring; furthermore, they lack effective interception and containment structures. Even if a leak is detected, the electrolyte may still spread rapidly, failing to prevent damage to the equipment and the surrounding environment. Furthermore, the distributed component layout results in a large overall footprint, low space utilization, and hinders the overall handling, commissioning, and maintenance of the equipment, severely restricting the standardized production and large-scale application of vanadium redox flow battery equipment. Utility Model Content

[0003] The purpose of this utility model is to provide an integrated vanadium redox flow battery skid-mounted leak-proof container to solve the aforementioned technical problems in the prior art; the preferred technical solutions among the various technical solutions provided by this utility model can produce many technical effects, as detailed below.

[0004] To achieve the above objectives, the present invention provides the following technical solution: This utility model provides an integrated storage device for a skid-mounted, leak-proof container for vanadium redox flow batteries, comprising a skid-mounted container, a vanadium redox flow battery device, and a leak-proof device. The vanadium redox flow battery device is housed within the skid-mounted container; the leak-proof device is also housed within the skid-mounted container and includes a dike assembly and a detection assembly. The dike assembly surrounds the outside of the vanadium redox flow battery device, and the detection assembly is used for leak detection.

[0005] Preferably, the vanadium redox flow battery device includes a cathode tank, an anode tank, and a stack unit, wherein: the cathode tank and the anode tank are symmetrically arranged on both sides of the stack unit, and the cathode tank, the anode tank, and the stack unit are connected by pipelines; the dike assembly is arranged around the cathode tank, the anode tank, and the stack unit.

[0006] Preferably, the cofferdam assembly includes a plurality of protective cofferdam plates welded together in sequence; the protective cofferdam plates are made of PPH (polypropylene copolymer) sheets.

[0007] Preferably, a drain pipe is connected to the bottom side of the cofferdam assembly on the skid-mounted container.

[0008] Preferably, the detection component includes a first chain sensor, which is disposed at the edge where the cathode storage tank is connected to the skid-mounted container base.

[0009] Preferably, the detection component includes a second chain sensor, which is disposed at the edge where the anode tank is connected to the skid-mounted container base.

[0010] Preferably, the vanadium redox flow battery skid-mounted leak-proof container integrated warehouse equipment includes an electronic control device. The skid-mounted container is provided with a first installation area and a second installation area that are independent of each other. The vanadium redox flow battery device and the electronic control device are respectively located in the first installation area and the second installation area.

[0011] Preferably, the skid-mounted container includes a container body, and a vertical partition is provided inside the container body, which divides the inner cavity of the container body into a first installation area and a second installation area.

[0012] Preferably, the electronic control device includes a BMS (Battery Management System) and EMS (Energy Management System) control cabinet and a PSC (Power Storage Converter) control cabinet, all of which are located in the second installation area.

[0013] Preferably, the skid-mounted container is provided with a first cabinet door and a second cabinet door at positions corresponding to the first installation area and the second installation area, respectively.

[0014] The skid-mounted, leak-proof containerized integrated storage device for vanadium redox flow batteries provided by this utility model has at least the following beneficial effects: I. Significantly improved integration, enabling standardized and convenient applications: By integrating the entire vanadium redox flow battery device into a skid-mounted container, the traditional scattered arrangement of components is broken, achieving integrated design and installation of the battery system. The skid-mounted container structure not only provides a stable and sealed installation space for the battery device but also offers excellent mobility, enabling overall transport, rapid deployment, and on-site commissioning, significantly shortening the installation cycle and reducing construction costs. Simultaneously, the integrated design facilitates standardized production and mass manufacturing, effectively improving product consistency and reliability, laying the foundation for the large-scale promotion of vanadium redox flow battery equipment.

[0015] II. Comprehensive upgrades to leak protection ensure system safety and environmental friendliness: The containment dike assembly, installed around the vanadium redox flow battery unit, forms a dedicated leak-proof interception zone. Even in the event of a leak, the electrolyte is quickly intercepted and contained within a defined area, preventing its spread to other areas of the skid-mounted container or the external environment. This effectively reduces the risk of electrolyte corrosion and environmental pollution, ensuring the safety and environmental friendliness of the equipment. Combined with detection components, real-time, comprehensive monitoring of leaks is achieved, enabling timely detection and feedback of leak signals. This facilitates rapid response and corrective action by personnel, further enhancing the system's safety level and reducing economic losses and safety hazards caused by leaks. III. Optimization of space utilization and ease of operation and maintenance: The airtight space of the skid-mounted container, combined with the rational layout of the dike components, maximizes the use of internal installation space while achieving leak prevention, significantly reducing the equipment's footprint compared to traditional distributed layouts. The integrated structural design also facilitates daily operation and maintenance. Staff can inspect and maintain the battery unit and leak prevention device through the pre-reserved passages and inspection ports of the skid-mounted container, effectively improving maintenance efficiency and reducing maintenance costs.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1: This utility model provides a skid-mounted, leak-proof containerized integrated storage device for vanadium redox flow batteries, referenced... Figures 1 to 7 As shown, the integrated container warehouse equipment for the vanadium redox flow battery device includes a skid-mounted container 1, a vanadium redox flow battery device 2, and a leak-proof device 3.

[0021] The vanadium redox flow battery device 2 is installed inside the skid-mounted container 1; the leak prevention device 3 is installed inside the skid-mounted container 1. The leak prevention device 3 includes a dike assembly 31 and a detection assembly 32. The dike assembly 31 is installed outside the vanadium redox flow battery device 2, and the detection assembly 32 is used for leak detection.

[0022] This utility model integrates the vanadium redox flow battery device 2 into a skid-mounted container 1. The integrated structure not only effectively reduces the overall size of the equipment and the floor space occupied, thereby effectively improving space utilization, but also facilitates overall transportation, rapid deployment and on-site commissioning, significantly shortening the installation cycle. At the same time, it can also provide a stable and sealed installation space for the battery device.

[0023] The dike assembly 31 can intercept and contain the leaked electrolyte within a limited area, preventing it from leaking out and spreading to the outside.

[0024] The detection component 32 captures electrolyte leakage signals in real time, enabling staff to respond quickly and take appropriate measures, thereby improving the level of safety protection and reducing economic losses and safety hazards caused by leakage failures.

[0025] Example 2: Example 2 is based on Example 1: like Figures 1 to 7 As shown, the vanadium redox flow battery device 2 includes a cathode tank 21, an anode tank 23, and a stack unit 22. The cathode tank 21 and the anode tank 23 are symmetrically arranged on both sides of the stack unit 22.

[0026] The cathode storage tank 21, the anode storage tank 23, and the fuel cell stack unit 22 are connected by pipelines.

[0027] Specifically, the cathode storage tank 21 and the cathode current collector of the fuel cell stack unit 22 are connected by a first pipeline to form a first circulation loop. A first circulation pump is installed on the first pipeline. The anode storage tank 23 and the anode current collector of the fuel cell stack unit 22 are connected by a second pipeline to form a second circulation loop. A second circulation pump is installed on the second pipeline. The cathode storage tank 21 and the anode storage tank 23 are connected by a connecting pipe, and a valve is installed on the connecting pipe.

[0028] Furthermore, the interior of the skid-mounted container 1 is equipped with a support frame 13, the fuel cell stack unit 22 is fixedly mounted on the upper side of the support frame 13, and the first circulation pump and the second circulation pump are mounted on the lower side of the support frame 13.

[0029] The cofferdam assembly 31 is installed outside the cathode tank 21, the anode tank 23 and the fuel cell stack unit 22.

[0030] This setup can precisely cover the core areas of electrolyte storage and transportation, concentrating leakage risk points within the protection scope, thereby further improving the targeting and reliability of leak prevention, ensuring that once a leak occurs, it can be quickly intercepted by a containment dike, minimizing the risk of leakage spread.

[0031] As an optional implementation, the cofferdam assembly 31 includes a plurality of protective weir plates welded together in sequence, which can effectively ensure the sealing of the connection and prevent leakage from the connection of the weir plates due to gaps in the connection.

[0032] The protective weir plate is made of PPH material, which has excellent corrosion resistance and can effectively resist the corrosive effect of the vanadium redox flow battery electrolyte, extending the service life of the weir assembly 31 and preventing the leakage prevention function from failing due to corrosion damage to the plate. At the same time, the PPH material also has good toughness and strength, and can withstand a certain impact and pressure, ensuring that the weir assembly 31 maintains structural stability during equipment operation and transportation, and continues to play a leakage prevention role.

[0033] As an optional implementation, a drain pipe is connected to the bottom side of the dike assembly 31 on the skid-mounted container 1.

[0034] In practical applications, when leakage is intercepted within the cofferdam component 31, workers can promptly and orderly drain the leakage through the drainage pipe, preventing it from accumulating within the cofferdam component 31 for an extended period. This prevents the accumulated leakage from overflowing the cofferdam component 31 due to excessively high liquid levels, thus avoiding further spread. Furthermore, it facilitates the centralized collection and treatment of the drained leakage, reducing environmental pollution from the electrolyte.

[0035] As an optional implementation, the detection component 32 includes a first chain sensor 321, which is located at the edge where the cathode storage tank 21 is connected to the base of the skid-mounted container 1.

[0036] The detection component 32 includes a second chain sensor 322, which is located at the edge where the anode tank 23 is connected to the base of the skid-mounted container 1.

[0037] In practical applications, gaps may easily appear at the connection between the storage tank and the base due to sealing aging, installation deviation, etc., which may lead to electrolyte leakage. The first chain sensor 321 and the second chain sensor 322 respectively detect the leakage points of the cathode storage tank 21 and the anode storage tank 23.

[0038] Preferably, both the first chain sensor 321 and the second chain sensor 322 are corrosion-resistant fluoroplastic coated chain sensors.

[0039] In practical applications, to further expand the leak detection range, a strip-shaped chain sensor can be arranged in the piping system of the vanadium redox flow battery device 2.

[0040] As an optional implementation, the vanadium redox flow battery skid-mounted leak-proof container integrated warehouse equipment includes an electronic control device 4. The skid-mounted container 1 is provided with a first installation area and a second installation area that are independent of each other. The vanadium redox flow battery device 2 and the electronic control device 4 are respectively installed in the first installation area and the second installation area.

[0041] This setup serves two purposes. First, the evaporation of electrolyte and temperature changes that may occur during the operation of the vanadium redox flow battery device 2 will not interfere with the precision components of the electronic control device 4, ensuring the stability and accuracy of the operation of the electronic control device 4 and avoiding control failures caused by environmental factors. Second, the independent installation of the vanadium redox flow battery device 2 and the electronic control device 4 facilitates their daily inspection and maintenance.

[0042] As an optional implementation, the skid-mounted container 1 includes a container body, and a vertical partition 11 is provided inside the container body, which divides the inner cavity of the container body into a first installation area and a second installation area.

[0043] The two independent installation areas make the functional allocation area clearer, avoid mutual interference between devices in different functional areas, and ensure the safety of the overall equipment.

[0044] As an optional implementation, the electrical control device 4 includes a BMS and EMS control cabinet 42 and a PSC control cabinet 41, both of which are located in the second installation area.

[0045] BMS and EMS control cabinet 42 is responsible for battery management and energy management, while PSC control cabinet 41 is responsible for power control. The centralized arrangement of the two can reduce the connection length and complexity of the control lines, reduce the risk of line failure, and facilitate the staff to conduct collaborative debugging and troubleshooting of each control unit, thereby improving control efficiency.

[0046] BMS and EMS control cabinet 42 and PSC control cabinet 41 are existing technologies and will not be described in detail.

[0047] As an optional implementation, the skid-mounted container 1 is provided with a first cabinet door and a second cabinet door at positions corresponding to the first installation area and the second installation area, respectively.

[0048] Specifically, the first cabinet door includes three sub-cabinet doors, which correspond to the cathode storage tank 21, the fuel cell stack unit 22, and the anode storage tank 23, respectively.

[0049] The skid-mounted container 1 also has ventilation windows on its container wall corresponding to the position of the second installation area.

[0050] The enclosure is also equipped with a ventilation device 12.
