[0002] As a crucial component of large-scale energy storage systems, the design of the chassis foundation structure of vanadium redox flow batteries is critical to the stability, ease of maintenance, and environmental adaptability of the device. Traditional chassis foundation structures often employ fixed or simple assembly methods, resulting in low installation accuracy, difficulty in adjustment, and inability to adapt to variations in micro-topography at different sites. Especially when deployed outdoors, they are susceptible to rainwater erosion, leading to water accumulation and impacting component lifespan. Furthermore, existing structures lack integrated adjustment capabilities, making it difficult to meet the flexible spatial layout requirements for battery module installation, maintenance, and heat dissipation. Summary of the Invention

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings.

[0017] Combination Figures 1-6 The present invention relates to a sliding rail chassis for a vanadium redox flow battery energy storage device, comprising a modular sliding rail assembly 100, a mounting base 200, an adjustable support assembly 300, and a honeycomb shock-absorbing pad 400.

[0018] The modular slide rail assembly 100 is fixed to the mounting base 200; the adjustable support assembly 300 and the honeycomb shock-absorbing pad 400 are both located inside the mounting base 200; the adjustable support assembly 300 and the honeycomb shock-absorbing pad 400 are connected for upper and lower support.

[0019] Furthermore, the V-shaped structure of the modular slide rail assembly 100 is arranged on both sides to ensure that the vanadium redox flow battery module can only move in the preset longitudinal forward and backward direction in the slide rail, providing precise lateral constraints.

[0020] Furthermore, the vanadium redox flow battery module allows for the addition or removal of modules along the length of the slide rail. The slide rail design supports multi-level socket splicing along the slide rail length.

[0021] Furthermore, the modular slide rail assembly 100 has an upper protruding structure and a lower recessed structure on both sides, which can realize the docking of multiple modular units and the vertical expansion of multiple vanadium redox flow battery energy storage devices.

[0022] The adjustable support assembly 300 consists of a hydraulic self-balancing support rod 301, an upper connecting plate 302, and a lower connecting plate 303. Together with the honeycomb shock-absorbing pad 400, it enables the entire vanadium redox flow battery energy storage device to maintain horizontal stability on a ±5° inclined ground.

[0023] Furthermore, the hydraulic self-balancing support rod 301 allows each support foot to be raised and lowered independently, compensating for unevenness in the installation ground.

[0024] Furthermore, the upper connecting plate 302 and the lower connecting plate 303 are the same size, but their thicknesses may differ. The load-bearing capacity of the longitudinal load can be adjusted by adjusting the thickness of the upper and lower connecting plates.

[0025] The honeycomb-shaped shock-absorbing pad 400 is located below the adjustable support component 300. It can be stacked in multiple layers to achieve overall stability of the vanadium redox flow battery energy storage device and reduce the risk of vanadium liquid precipitation in the vanadium redox flow battery.

[0026] The working principle of this utility model is as follows: This utility model's sliding rail chassis achieves stable deployment, rapid expansion, and environmental adaptability of a vanadium redox flow battery energy storage device through specific mechanical design. Its working principle relies entirely on the structural features, relative positions, and connections of each component, rather than external operation. The core components are: the modular sliding rail assembly 100 provides precise guidance and waterproof flow control; the adjustable support assembly 300 achieves automatic ground leveling; and the honeycomb shock-absorbing pad 400 absorbs vibration energy. These three components are integrated through the mounting base 200, forming a passive working mechanism. The principles of each component and the overall collaborative mechanism are described below: When the vanadium redox flow battery energy storage device is installed on this chassis, its weight is transferred to each component through the mounting base 200. The V-shaped structure and concave-convex end design of the modular slide rail assembly 100 automatically guide the lateral positioning and longitudinal expansion of the battery modules; the hydraulic self-balancing support rod 301 and connecting plate structure of the adjustable support assembly 300 respond to ground unevenness and automatically maintain horizontality; the multi-layer honeycomb hole structure of the honeycomb damping pad 400 deforms and dissipates energy under vertical loads, reducing vibration transmission. The entire system achieves adaptive stability through a purely mechanical structure, requiring no manual intervention.

[0027] Working principle of modular slide rail assembly 100: The structure of this component directly drives its guiding, expansion, and waterproofing functions. The slide rail assembly 100 has a V-shaped structure with a flat top and a concave bottom, fixed to both sides of the bottom surface of the mounting base 200. The downward-facing slope of its V-shaped groove allows rainwater to flow naturally down the slope, preventing water accumulation and intrusion into the battery module above the slide rail. Simultaneously, the structural difference between the two ends of the slide rail assembly is that one end protrudes from the mounting base, while the other end is recessed to form a socket interface. When multiple chassis are longitudinally connected, the protruding end automatically engages with the recessed end of the adjacent slide rail assembly, achieving modular expansion through physical restraint. The modular slide rail assembly slides on a rigid track, constraining the battery module to move only along a preset longitudinal direction, achieving a positioning accuracy of ±0.5mm.

[0028] Working principle of adjustable support component 300: This component achieves automatic leveling through a layered structure. It consists of a hydraulic self-balancing support rod 301, an upper connecting plate 302, and a lower connecting plate 303, with the bottom surface of the lower connecting plate 303 vertically buffered and supported by honeycomb-shaped shock-absorbing pads 400. The hydraulic self-balancing support rod 301 is fixedly connected to the lower connecting plate 303 and hingedly connected to the upper connecting plate 302. When the ground tilts, the hydraulic medium (such as oil) within the support rod 301 flows automatically according to the pressure difference, driving the support rod to extend and retract (this hydraulic self-balancing support rod uses a mature product from the existing technology); this keeps the upper connecting plate 302 level, while the lower connecting plate 303 adapts to terrain changes through the shock-absorbing pads 400. Structurally, the evenly distributed design of multiple support rods 301 ensures load dispersion and automatically compensates for height differences on ±5° inclined ground without the need for external adjustment (the hydraulic self-balancing support rod adopts a mature technology in the existing technology to be hinged to the upper connecting plate, and the hinged support position has a certain horizontal relative displacement margin to avoid structural self-locking problems when the upper connecting plate is tilted relative to the lower connecting plate).

[0029] Working principle of honeycomb shock-absorbing pad 400: The multi-layered honeycomb structure of the shock-absorbing pad 400 directly dissipates energy. It is embedded and fixed to the top surface of the mounting base 200, directly below the adjustable support assembly 300, and vertically elastically supports the connecting plate 303. The axial direction of the 5mm diameter honeycomb pores is aligned with the load direction; when the device is subjected to vibration and impact, the elastic deformation of the pore walls (such as nitrile rubber) absorbs kinetic energy, and the deformation path is increased by coating anti-slip adhesive layers between the multi-layered stacks, dissipating energy layer by layer. This reduces the vibration amplitude transmitted to the battery module and lowers the risk of vanadium liquid precipitation. Structurally, the total thickness of the shock-absorbing pad, such as 30mm, matches the maximum stroke of the support rod 301, ensuring seamless coordination of the shock-absorbing function during leveling.

[0030] Collaborative working mechanism and overall effect: Each component is physically integrated via a high-strength alloy steel frame structure of the mounting base 200: the slide rail assembly 100 is fixed to both sides of the base's bottom surface, providing basic guidance for the battery module; the support assembly 300 and the shock-absorbing pad 400 are located inside the base, connected vertically to form a vertical stabilizing chain. When the device is deployed, the V-shaped guide and extension structure of the slide rail assembly first addresses environmental factors such as rainwater; the hydraulic leveling structure of the support assembly responds to terrain changes; and the shock-absorbing pad absorbs residual vibrations. These three components work together to maintain overall stability under static and dynamic loads. The final results include: waterproof guidance to prevent corrosion, ±0.5mm extension accuracy to improve deployment efficiency, automatic leveling to adapt to complex terrain, and shock-absorbing design to extend battery life.

[0031] In this embodiment, the chassis is installed on a ±3° inclined ground: the V-shaped groove of the slide rail assembly 100 guides rainwater to the drainage ditch; the hydraulic support rod 301 of the support assembly 300 automatically extends and retracts, keeping the upper connecting plate 302 horizontal; the three-layer stacked structure of the shock-absorbing pad 400 buffers wind load vibration. The entire process is completed without manual intervention, driven by the structure itself. This design solves the problems of low installation accuracy and poor waterproofing of traditional chassis, and is suitable for scenarios involving frequent expansion of new energy power plants.

[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
