Description

Technical Field

[0001] This utility model relates to the field of base technology, and in particular to a multi-directional shockproof fixing base for energy storage cabinets. Background Technology

[0002] An energy storage cabinet is an integrated and modular energy storage system device, usually adopting a container or cabinet structure. The fixed base is a reinforced installation platform specifically designed for energy storage cabinets, capable of resisting multi-directional seismic forces and vibration impacts. It is not only a simple support structure, but also a key device to ensure the structural safety, stable operation, and prevention of secondary disasters of the energy storage system under extreme conditions such as earthquakes and vibrations.

[0003] Traditional energy storage cabinet anti-vibration mounting bases typically employ rigid connections or simple unidirectional (mainly horizontal) damping designs. A typical structure includes a rigid base frame fixed to the ground with anchor bolts. Rubber pads or simple shear hinges may be installed between the base and the cabinet. Traditional bases are primarily designed to withstand horizontal shear forces. However, seismic waves are complex, multidimensional movements, including vertical turbulence and torsional moments. A single-dimensional anti-vibration design cannot effectively absorb and dissipate multidimensional impact energy during an earthquake, potentially leading to cabinet overturning or damage to internal battery modules due to mutual compression. Using rigid frames and point-fixed points (such as anchor bolts) allows seismic energy to be directly transmitted to the cabinet structure through a limited number of fixed points, easily causing stress concentration at connection points, leading to structural plastic deformation or tearing and creating safety hazards. Traditional rubber damping pads are prone to aging, creep, or permanent deformation after repeated or significant vibrations, resulting in irreversible degradation of damping performance. Their performance parameters are fixed and cannot be adaptively adjusted according to vibration intensity, exhibiting poor adaptability to seismic waves of different frequencies and amplitudes. Utility Model Content

[0004] The technical problem this invention aims to solve is that traditional bases, due to their singular seismic design, primarily address horizontal shear forces while neglecting vertical and torsional vibrations, suffer from insufficient protection under complex multidimensional seismic loads. Secondly, this singular seismic protection mechanism, combined with a rigid point-fixed structure, inevitably concentrates undissipated impact energy at a few fixed points, causing severe stress concentration and structural damage risks. Finally, the combined effect of these two factors, coupled with the lack of adaptive adjustment and performance recovery capabilities of traditional damping elements, causes the seismic performance of the entire base to deteriorate sharply or even completely fail after one or more strong earthquakes, making it impossible to guarantee the long-term safety of the energy storage cabinet.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A multi-directional shockproof fixing base for energy storage cabinet includes a placement platform, a distributed frame integrated at the bottom of the placement platform, an abutment platform inserted into the bottom of the distributed frame, and a protective shell sleeved around the abutment platform. The distributed frame bears pressure on the placement platform and connects to the abutment platform below for stable installation in the middle. The protective shell protects the shock-absorbing mechanism inside the abutment platform. The shock-absorbing mechanism includes a universal ball joint module and spring columns hinged around the universal ball joint module. A second disc spring is provided between the spring columns and the universal ball joint module. Several sets of spring columns are arranged in an X shape.

[0006] The beneficial effects of this utility model are: through the coordinated design of the distributed frame and the bottom grid frame, the concentrated load borne by the traditional point-fixed structure is transformed into a uniformly distributed surface load, which greatly reduces the stress peak at key connection points. The core universal ball joint module and the X-shaped spring column combine to form a spatial adaptive vibration reduction system, which can simultaneously and efficiently buffer the combined seismic impact from the horizontal, vertical and torsional directions, fundamentally solving the problem of stress concentration and structural damage caused by the single dimension and rigid connection of traditional solutions.

[0007] Furthermore, the placement platform is divided into a sandwich panel and a sleeve plate that wraps around the sandwich panel, and a flexible sleeve that wraps around the sleeve plate. Both the sandwich panel and the sleeve plate are provided with several sets of insertion holes in an array, and an installation sleeve is provided between two sets of insertion holes.

[0008] Furthermore, the bottom of the distributed frame is integrally formed with a base plate and an integrated frame sleeved on the outside. The base plate is covered with a sleeve, and slots are opened at all four edges of the integrated frame. Several sets of corresponding insertion holes and partition holes for mounting sleeves are arrayed on the base plate. A grid frame is fixed to the bottom of the distributed frame.

[0009] Furthermore, several sets of damping sleeves and collars hinged to the damping sleeves are fixedly connected in an array on the grid frame. Vertical spring rods are vertically installed inside the damping sleeves. Several sets of radial spring rods that abut against the inner wall of the damping sleeves are installed circumferentially on the outside of the vertical spring rods. A spherical shell is fixedly connected to the end of the vertical spring rod. The collars are arranged in several stacked sets. A first disc spring is provided between two sets of collars. The center of the bottom first disc spring has a ball that is hinged to the spherical shell. Several sets of extension plates are fixedly connected circumferentially on the outside of the collars. Inserts and elastic plates fixedly connected to the bottom of the inserts are inserted into the extension plates. The elastic plates are used to be embedded in the partition holes. A sensing ball is fixedly connected to the top of the insert. A pressure sensor is installed inside the sensing ball. A floating plate abuts the end of the several sets of collars away from the damping sleeve. Insert plates with insertion slots are fixedly connected around the floating plate.

[0010] Furthermore, a sleeve is fitted around the outer edge of the protective shell, and through slots corresponding to the sleeve are opened on both sides of the protective shell. A pressure plate is arranged parallel to the center of the bottom of the protective shell, and several sets of damping blocks are arranged in an array at the bottom of the pressure plate. Inside the protective shell are two sets of parallel shock-absorbing mechanisms, with the upper pressure-bearing platform of the shock-absorbing mechanism connected to the lower pressure plate.

[0011] Furthermore, the outer side of the universal ball joint module is provided with a pressure sleeve that connects the abutment platform and the pressure plate respectively. A first hydraulic damper and a third disc spring with elastic setting are provided between the pressure sleeve and the universal ball joint module. Several sets of shock-absorbing grooves are opened around the periphery of the pressure sleeve.

[0012] Furthermore, both the contact platform and the pressure plate are fixedly connected to pressure seats with corresponding spring columns. The pressure seat has a fourth disc spring connected to the spring column at its center. The pressure seat has a second hydraulic damper hinged to the fourth disc spring outside. The end of the second hydraulic damper away from the pressure seat is connected to a guide rod, and the guide rod and the spring column are Y-shaped.

[0013] Furthermore, a connecting sleeve is provided at the junction of the two sets of damping mechanisms. The connecting sleeve passes through the through groove and abuts against the housing. Inside the connecting sleeve is a third hydraulic damper and a fluid core located inside the third hydraulic damper.

[0014] The beneficial effects of adopting the above-mentioned further scheme are as follows: The use of a parallel or series design of multi-stage disc springs and hydraulic dampers, with the disc springs providing the main restoring force and exhibiting excellent fatigue resistance, and the hydraulic dampers providing controllable energy consumption, allows the base to automatically reset after an earthquake due to the elastic potential energy of the disc springs. In particular, the first disc spring between the collars and the second disc spring in the spring column can push the structure back to its original position after undergoing large deformations, effectively overcoming the defects of traditional rubber pads such as easy aging and creep, ensuring the long-term stability of the seismic performance. Furthermore, an innovative pressure sensor is integrated into the sensing sphere of the grid frame, enabling real-time monitoring of load changes at various points. Attached Figure Description

[0017] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0018] In the description of this application, it should be understood that the terms "upper," "lower," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In the description of this application, "a plurality of" means two or more, unless otherwise precisely specified.

[0019] Example 1; as Figures 1-5 As shown, the platform 1 for supporting the energy storage cabinet is composed of a sandwich panel 101, a sleeve plate 102 and an outer flexible sleeve 105. The insertion holes 103 and mounting sleeves 104 arranged in an array on the platform are used to fit the cabinet fixing bolts. The bottom of the placement platform 1 is integrated with a distributed frame 2, which consists of a base plate 202, an integrated frame 204 and a grid frame 206 at the bottom. Its core function is to convert the concentrated load of the cabinet into a uniformly distributed surface load through the partition holes 203 on the base plate 202 and the grid frame 206. The grid frame 206 is fixedly connected with an array of shock-absorbing sleeves 210. Each shock-absorbing sleeve 210 has a vertical spring rod 217 and a radial spring rod 212 inside, forming the first shock-absorbing unit. The bottom of the distributed frame 2 is inserted with an abutment platform 4. The abutment platform 4 is covered by a protective shell 3. The core components of the multi-directional shock-absorbing mechanism are set inside the protective shell 3.

[0020] When in operation, the energy storage cabinet is fixed on the placement platform 1, and its weight is evenly transferred to multiple shock-absorbing sleeves 210 units of the grid frame 206 through the distributed frame 2. When encountering vertical impacts such as earthquakes, the vertical spring rod 217 is compressed first, absorbing vertical kinetic energy. When horizontal shear force occurs, the collar 207 undergoes lateral deformation through the first disc spring 208 between its superimposed structures, and achieves flexible displacement through the hinge between the ball 209 and the spherical shell 211, thereby dissipating horizontal energy. The radial spring rod 212 further constrains the swing of the vertical spring rod 217, enhancing stability. The entire grid frame 206 system, through its distributed layout, achieves the initial dispersion and absorption of impact energy.

[0021] Example 2: Please refer to Figure 1 - Figure 6 Based on Embodiment 1, the core shock absorption mechanism inside the protective shell 3 has been further enhanced. This mechanism includes two sets of parallel shock absorption systems with the universal ball joint module 307 as the core. The outer side of the universal ball joint module 307 is connected to the abutment platform 4 and the pressure plate 303 via a pressure sleeve 305. A first hydraulic damper 306 and a third disc spring 315 are provided between the pressure sleeve 305 and the universal ball joint module 307. Multiple sets of spring columns 308 are arranged in an X-shape around the universal ball joint module 307. A second disc spring 314 is provided between the spring column 308 and the universal ball joint module 307. The two ends of the spring column 308 are connected to the abutment platform 4 and the pressure plate 303 via a pressure seat 309. A fourth disc spring 317 is provided at the center of the pressure seat 309, and a second hydraulic damper 310 is also hinged to the outside of the pressure seat 309 in a Y-shape with the guide rod 311. The two sets of shock absorption mechanisms are connected by a connecting sleeve 313, and a third hydraulic damper 318 is provided inside the connecting sleeve 313.

[0022] When working, the core damping mechanism begins to play a leading role when complex multidimensional seismic impacts (such as torsional moments) are transmitted to the base. As the core node for spatial movement, the universal ball joint module 307 allows for small angular displacements in multiple directions between the abutment platform 4 and the pressure plate 303, thereby adapting to torsional and combined impacts. The X-shaped arrangement of spring columns 308 system deforms collaboratively under horizontal, vertical, and oblique impacts. The second disc spring 314 provides the main elastic restoring force, while the second hydraulic damper 310 effectively dissipates impact kinetic energy and suppresses oscillations. The first and third hydraulic dampers 318 provide additional damping dissipation for impacts in different directions, respectively. The connecting sleeve 313 ensures the synchronous movement of the two damping mechanisms, further improving the overall stability of the system. The damping block 304 at the bottom of the pressure plate 303 contacts the ground, providing final frictional damping.

[0023] The above working principles can be summarized as follows: the working principle of the multi-directional shockproof fixed base of the energy storage cabinet is a multi-level, multi-dimensional coordinated energy dissipation and adaptive reset process; Its core lies in the fact that the distributed grid frame 206 initially disperses and absorbs the impact energy, while the universal ball joint module 307 and the X-shaped spring column 308 form a two-level defense mechanism to jointly cope with complex seismic loads. The specific process is as follows: the impact energy is first dispersed and absorbed by a large number of damping sleeves 210 units in the grid frame 206 (vertical and horizontal initial damping); the residual energy that is not completely dissipated, especially torsional and compound impacts, is transferred to the core damping mechanism inside the protective shell 3. The universal ball joint module 307 enables multi-directional degree of freedom adaptation. The X-shaped spring column 308 works in conjunction with each hydraulic damper to convert impact kinetic energy into heat energy dissipation. At the same time, the disc springs at each stage (first, second, third, and fourth disc springs 317) provide reliable elastic restoring force after impact, driving the entire system to reset and avoiding residual deformation. The sensing ball 216 on the top of the insert 214 monitors the load in real time, providing data support for system status monitoring.

[0024] Based on Embodiment 1 and Embodiment 2, key structural components such as the placement platform 1, the distributed frame 2, and the protective shell 3 are recommended to be made of Q345B low alloy high strength steel to ensure strength and toughness. The disc spring material should be selected from 60Si2MnA or 50CrVA spring steel and heat-treated to obtain high fatigue life. The flexible sleeve 105 can be made of neoprene rubber or polyurethane elastomer. The fluid core 312 refers to the core cavity component inside the third hydraulic damper 318 that realizes the fluid damping effect. Its interior is filled with high-viscosity damping fluid (such as silicone oil). The special flow channel design can generate nonlinear damping force. The fluid core 312 is the core damping element of the third hydraulic damper 318. It is usually composed of a specially designed valve system and porous media, and its interior is filled with high-viscosity damping fluid. When the connecting sleeve 313 is stretched or compressed, it forces the damping fluid to flow through the narrow channels or pores of the fluid core 312, generating huge fluid resistance, thereby converting mechanical kinetic energy into heat energy and achieving efficient energy dissipation to suppress the relative sway between the two sets of damping mechanisms. The Y-shaped configuration describes the triangular stable structure formed by the guide rod 311, the second hydraulic damper 310, and the spring column 308, which effectively suppresses lateral deformation. This base constitutes a complete shockproof system from energy dispersion and multi-directional adaptive buffering to intelligent graded energy dissipation and automatic recovery.

[0025] Based on the aforementioned two-stage damping principle, another noteworthy feature is the self-adaptive and long-life characteristics of this base. By employing a combination of fatigue-resistant disc springs and hydraulic dampers, traditional rubber damping pads are replaced, fundamentally solving the performance degradation problem caused by material aging and creep. Whether it is the grid frame 206 unit in Example 1 or the core damping mechanism in Example 2, their design ensures that they can automatically return to their initial state after experiencing a strong earthquake, guaranteeing the long-term stability and reliability of the shock-absorbing performance.

[0026] Specifically, the pressure sensor (located inside the sensing sphere 216) is described as follows: The pressure sensor inside the sensing ball 216 is used to monitor the specific pressure value borne by each shock-absorbing sleeve 210 unit on the grid frame 206 in real time. When the pressure in a certain area rises abnormally, it can indicate that the point may be subjected to excessive impact load or there may be structural hazards. The data can be transmitted to an external monitoring system to realize online monitoring and early warning of the health status of the base. Miniature hydrostatic sensors or load cells, such as Honeywell's MLH series or STS's ATM.ECO series, can be used depending on the requirements. The range is 0-10 tons, the output signal is 4-20mA, and they have good stability and overload resistance. They are used to monitor the load distribution of each support point in real time. To comprehensively monitor seismic response, a triaxial accelerometer, such as ADI's ADXL355, can be installed inside the protective shell 3 or on the platform 1 to record acceleration data of the base in three directions during an earthquake, and to conduct safety assessments and early warnings. Hydraulic damper cylinder body and piston rod: The cylinder body is made of seamless steel pipe, and the piston rod is made of hard chrome plated 45 steel for corrosion resistance and wear resistance.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
