Description

Technical Field

[0001] This utility model relates to the field of battery equipment, and more particularly to a capacity container for storing flow batteries. Background Technology

[0002] Flow batteries, with their advantages of power-capacity decoupling, high safety, long lifespan, and ease of scalability, have become one of the core technologies in the field of large-scale, long-term energy storage. Their energy storage capacity is determined by the volume and concentration of the electrolyte; therefore, the "electrolyte tank" is the core carrier of the flow battery's capacity.

[0003] Containerized design, due to its standardization, modularity, convenient transportation and installation, and controllable quality from factory prefabrication, has been widely used in the field of lithium battery energy storage. However, directly applying this design to the electrolyte storage tanks of flow batteries faces three major challenges:

[0004] Insufficient volume and weight capacity: The electrolyte storage tank (especially when fully loaded) accounts for the majority of the volume and weight of the flow battery system. The internal space and floor load-bearing capacity of existing 20-foot and 40-foot standard containers cannot meet the size and weight requirements of ultra-large capacity storage tanks.

[0005] Structural strength mismatch: When the storage tank is fully loaded, it will generate huge hydrostatic pressure. The side walls and bottom plates of the standard container can only bear the weight of ordinary cargo. It is easy to deform when used directly as a liquid container. If it is reinforced excessively, it will compress the internal volume and increase the container's weight.

[0006] Sealing and corrosion prevention are challenging: The electrolytes commonly used in flow batteries (such as vanadium electrolyte) are highly corrosive, and the storage tanks need to be reliably sealed for a long time to avoid leakage (to prevent environmental pollution and equipment damage). However, converting ordinary shipping containers into liquid containers that meet this requirement is technically difficult and costly. Utility Model Content

[0007] To address the aforementioned problems in the prior art, this utility model proposes a capacity container for storing flow batteries, which has high structural strength, strong load-bearing capacity, and is easy to construct on-site.

[0008] Specifically, this utility model proposes a capacity container for storing flow batteries, including a container body and a top cover, wherein the top cover is detachably disposed on the top of the container body, and the container body includes:

[0009] The base frame includes a first support frame disposed at the bottom and a steel floor disposed on the first support frame;

[0010] Two end walls are vertically installed at both ends along the length of the base frame and are welded and fixed to the steel floor.

[0011] Two side walls are vertically arranged on both sides of the base frame in the width direction and are welded and fixed to the steel floor. The side walls and end walls cooperate with the base frame to form the box to provide space for accommodating the flow battery.

[0012] An intermediate wall is arranged parallel to the end wall and located inside the box. The intermediate wall is used to divide the space inside the box.

[0013] According to one embodiment of the present invention, the end wall and side wall are welded and fixed to the steel floor, and the welding method is continuous full welding.

[0014] According to one embodiment of the present invention, the first support frame includes a plurality of first square tubes arranged in an interlaced manner.

[0015] According to one embodiment of the present invention, both the end wall and the side wall include an outer corrugated plate and an inner second support frame, wherein the second support frame includes multiple second square tubes arranged in an interlaced manner.

[0016] According to one embodiment of the present invention, there are multiple intermediate walls, which divide the internal space of the box into multiple independent compartments.

[0017] According to one embodiment of the present invention, an inclined support block is provided at the connection between the intermediate wall and the side wall. One end of the inclined support block is connected and fixed to the intermediate wall, and the other end is connected and fixed to the side wall and / or the base frame.

[0018] According to one embodiment of the present invention, the capacity container further includes a third-party pipe, which is arranged horizontally along the top inner edge of the end wall and / or side wall, and a downward-opening channel steel is provided at the bottom edge of the top cover, the channel steel being fixed in conjunction with the third-party pipe.

[0019] According to one embodiment of the present invention, the capacity container further includes a sealing strip, which is disposed inside the channel steel and / or on top of the third-party tube.

[0020] According to one embodiment of the present invention, a plurality of manhole covers are provided on the top cover, and the plurality of manhole covers are located above the internal equipment of the housing.

[0021] According to one embodiment of the present invention, the capacity container further includes a plurality of compensating pads, which are spaced apart at the bottom of the first square tube.

[0022] This utility model provides a capacity container for storing flow batteries. Through the first support frame and steel floor of the base frame, the corrugated plates of the end walls / side walls and the second support frame, and the intermediate wall, the structural strength is greatly improved. It can stably support the electrolyte storage tank with ultra-large volume / weight, and is combined with a detachable top cover to facilitate on-site construction.

[0059] Figure 1 A schematic diagram of the structure of a capacity container according to an embodiment of the present invention is shown. Figure 2 A bottom view of the base frame according to an embodiment of the present invention is shown. Figure 3 A top view of the container body according to an embodiment of the present invention is shown. As shown, a capacity container 100 for storing electrolyte tanks for flow batteries mainly includes a container body 101 and a top cover 102. The top cover 102 is detachably mounted on the top of the container body 101, facilitating the hoisting of flow battery-related components from the top of the container body 101 and improving loading and unloading convenience.

[0060] Furthermore, the enclosure 101 includes a base frame 103, two end walls 104, two side walls 105, and a middle wall 106. (Refer to...) Figure 2 The base frame 103 includes a first support frame 107 at the bottom and a steel floor 109 disposed on the first support frame 107. The first support frame 107 is used to enhance the load-bearing capacity of the base frame 103, and the steel floor 109 provides a stable bearing surface for the flow battery-related components. (Reference) Figure 1 Two end walls 104 are vertically installed at both ends of the base frame 103 along its length, and two side walls 105 are vertically installed on both sides of the base frame 103 along its width. Both end walls 104 and side walls 105 are welded and fixed to the steel floor 109. The end walls 104 and side walls 105, together with the base frame 103, enclose a space to accommodate the electrolyte storage tank for the flow battery. (Reference) Figure 3 The middle wall 106 is parallel to the end wall 104 and located inside the box 101. It is used to divide the space inside the box 101. Multiple independent areas can be divided according to needs, which can be adapted to multiple sets of flow battery electrolyte storage tanks or realize the separate storage of different electrolytes, and improve the overall structural strength.

[0061] In some examples, the end wall 104, side wall 105, and steel floor 109 are fixedly connected by welding, specifically using a continuous full-weld welding method. From a structural and functional perspective, welding itself ensures a stable overall connection between the end wall 104, side wall 105, and base frame 103, providing basic structural support for the housing 101 to support related components of the flow battery (such as the electrolyte storage tank). The continuous full-weld method completely eliminates gaps at the connection between the wall and the steel floor 109, preventing electrolyte leakage at the source. It also enhances the overall sealing of the housing 101, meeting the long-term storage requirements of corrosive electrolytes in flow batteries and preventing environmental pollution or equipment damage caused by leakage.

[0062] refer to Figure 2 In some examples, the structure of the first support frame 107 consists of multiple interlaced first square tubes 108. As the core load-bearing component of the base frame 103, the core function of the first support frame 107 is to provide stable support for the steel floor 109 and the flow battery components supported above it. The interlaced arrangement of multiple first square tubes 108 can form a mesh-like load-bearing frame. This structure can evenly distribute the weight of the flow battery components (especially the tank full of electrolyte) throughout the base frame 103, avoiding excessive local stress that could cause deformation of the base frame 103. This effectively improves the overall load-bearing capacity and structural stability of the base frame 103, ensuring that the base frame 103 can withstand the weight load of the flow battery components for a long time.

[0063] Figure 5 A schematic diagram of the end wall structure according to an embodiment of the present invention is shown. Figure 6A schematic diagram of the side wall structure according to an embodiment of the present invention is shown. As shown in the figure, in some examples, both the end wall 104 and the side wall 105 adopt a double-layer composite structure. The outer layer is a corrugated plate 110, and the inner layer is a second support frame 111. The corrugated plate 110 and the second support frame 111 can be welded together. The second support frame 111 is composed of multiple interlaced second square tubes 112. The outer corrugated plate 110, due to its morphological characteristics, can effectively improve the deformation resistance of the wall and provide basic structural support for coping with the hydrostatic pressure generated when the electrolyte storage tank of the flow battery is fully loaded. The interlaced second square tubes 112 of the inner layer form a grid-like support frame, which can further strengthen the overall structural strength of the wall. In conjunction with the corrugated plate 110 structure, it ensures that the end wall 104 and the side wall 105 are not prone to deformation under long-term hydrostatic pressure, and at the same time provides a stable enclosure structure for the storage space inside the box 101, adapting to the safe storage requirements of the flow battery related components.

[0064] In some examples, multiple intermediate walls 106 are used, which together divide the internal space of the enclosure 101 into multiple independent compartments. From a practical application perspective, the design of multiple independent compartments can flexibly adapt to the storage requirements of flow batteries. It can accommodate multiple sets of electrolyte tanks according to the energy storage capacity plan, achieving modular capacity expansion; it can also be used to separate and store different types of electrolytes (such as positive and negative electrolytes), avoiding the safety risks caused by mixing different electrolytes. At the same time, the independent compartments can also distribute the weight load of individual components within each compartment. The intermediate walls 106 can share the hydrostatic pressure borne by the side walls 105, reducing the load-bearing pressure on the local structure of the enclosure 101, further improving the overall structural stability and operational safety of the enclosure 101.

[0065] Figure 4 yes Figure 3 An enlarged schematic diagram of section B is shown. As illustrated, in some examples, an inclined support block 113 is provided at the connection between the intermediate wall 106 and the side wall 105. One end of the inclined support block 113 is connected and fixed to the intermediate wall 106, and the other end is connected and fixed to the side wall 105 and / or the base frame 103. Specifically, the connection between the intermediate wall 106 and the side wall 105 is a stress concentration area inside the container 101. Especially after the compartment carries the electrolyte storage tank, this area needs to withstand the lateral pressure from the weight of the tank. The inclined support block 113 can distribute the pressure to the side wall 105 and / or the base frame 103 through inclined force distribution, effectively strengthening the structural strength of the connection and preventing wall deformation caused by long-term stress. Simultaneously, during container transportation, the inclined support block 113 can also limit the movement of the storage tank inside the compartment, preventing the tank from shifting due to bumps, ensuring the transportation safety of the storage tank and the internal structure of the container 101, and adapting to the storage and transportation needs of flow battery electrolyte storage tanks.

[0066] Figure 7 A partial cross-sectional view of the detachable structure of the top cover according to an embodiment of the present invention is shown. As shown, in some examples, the container 100 further includes a third-party tube 114, which is horizontally disposed on the top inner edge of the end wall 104 and / or side wall 105. Correspondingly, the bottom edge of the top cover 102 is provided with a downward-opening channel steel 115, which is fixed to the third-party tube 114 through an upper and lower structural fit. In fact, the horizontally arranged third-party tube 114 provides a stable support reference for the detachable installation of the top cover 102, and the downward-opening channel steel 115 can form a snap-fit ​​with the third-party tube 114 to ensure the positioning accuracy of the top cover 102 when connected to the container body 101, thereby ensuring the stability of the top cover 102 after installation. At the same time, this fit structure facilitates the disassembly of the top cover 102. When it is necessary to lift the electrolyte storage tank into the container 101, the channel steel 115 and the third-party pipe 114 can be separated to remove the top cover 102 upwards, and the tank loading and unloading can be completed from the top. This solves the problem that large-volume storage tanks are difficult to enter and exit through the side door or end door of the container, and takes into account both structural stability and ease of loading and unloading.

[0067] In some examples, the capacity container 100 is also equipped with a sealing strip 116, which is located inside the channel steel 115 and / or on top of the third-party pipe 114. While the cooperation between the channel steel 115 and the third-party pipe 114 secures the connection between the top cover 102 and the container body 101, small gaps may exist at their mating surfaces. The sealing strip 116 fills these gaps, thus forming a complete sealing structure. This sealing structure prevents corrosive gases generated by the evaporation of electrolyte inside the container body 101 from leaking outwards, avoiding corrosion to the external environment or equipment. Furthermore, it prevents external dust, moisture, and other impurities from entering the container body 101, preventing contamination of the electrolyte or affecting the normal operation of internal equipment. This adapts to the long-term storage requirements of the corrosive electrolyte in flow batteries, ensuring the sealing reliability of the capacity container 100.

[0068] Figure 8 yes Figure 1 An enlarged schematic diagram of part A in the image. (Combined with...) Figure 1As shown, in some examples, the top cover 102 has multiple manhole covers 117, and the positions of these manhole covers 117 correspond to the positions of the internal equipment (such as the pipeline distributor of the electrolyte storage tank, the circulation pump, etc.) of the housing 101, located above the internal equipment. From the perspective of maintenance convenience, this design eliminates the need to disassemble the entire top cover 102. Workers only need to open the corresponding manhole cover 117 to directly inspect, maintain, or debug the internal equipment below, significantly reducing the workload and time costs during maintenance. It also avoids potential damage to the sealing structure caused by frequent disassembly of the top cover 102, balancing maintenance convenience and structural stability. Preferably, a sealing element (such as a rubber sealing ring) is provided between the manhole cover 117 and the top cover 102 to ensure a tight seal when closed, preventing external impurities from entering or internal corrosive gases from leaking out.

[0069] refer to Figure 2 In some examples, the container 100 also includes multiple compensating pads 118, which are spaced apart and fixed to the bottom of the first square tube 108. Considering the load-bearing capacity of the base frame 103, the first square tube 108, as the core component of the first support frame 107, primarily bears the weight of the container 101 and its internal flow battery components (such as a tank fully loaded with electrolyte). The compensating pads 118 increase the contact area between the first square tube 108 and the ground, evenly distributing the concentrated load borne by the first square tube 108 to the ground, preventing ground subsidence or deformation of the first square tube 108 due to excessive local pressure. Simultaneously, the spaced arrangement ensures effective load distribution while avoiding material waste from excessive pad use, further improving the load-bearing stability and economic efficiency of the base frame 103, and adapting to the heavy load-bearing requirements of the flow battery tank.

[0070] The capacity container for storing flow batteries provided by this utility model has the following advantages:

[0071] 1. Strong load-bearing capacity: Through the combined design of "first support frame of the base frame + compensation pad, corrugated plate of end wall / side wall + second support frame, middle wall + oblique support block", the structural strength is greatly improved and it can stably support electrolyte storage tanks with ultra-large volume / weight.

[0072] 2. Excellent sealing and corrosion protection performance: "The continuous full welding of the steel floor and the end wall / side wall, and the combination of the top cover and the channel steel of the box body + third-party pipe + sealing strip" form a double seal, which effectively prevents electrolyte leakage and corrosive media intrusion.

[0073] 3. High degree of modularity and prefabrication: All components of the container (base frame, end walls, side walls, intermediate walls, etc.) can be prefabricated and welded in the factory. Only simple processes such as "top cover installation and tank hoisting" are required on site, which facilitates large-scale production and rapid deployment.

[0074] 4. Convenient maintenance: The removable top cover and manhole cover make the inspection and maintenance of the storage tank and internal pipelines and equipment more efficient, without the need to disassemble the entire container.

[0075] It will be apparent to those skilled in the art that various modifications and variations can be made to the exemplary embodiments of the present invention without departing from the spirit and scope of the present invention. Therefore, it is intended that the present invention cover modifications and variations falling within the scope of the appended claims and their equivalents.
