Description

Technical Field

[0001] This utility model relates to the field of battery compartment technology, and in particular to an integrated foundation for a prefabricated energy storage battery compartment firewall. Background Technology

[0002] As the global energy structure shifts towards renewable energy, energy storage technology has become a key means to address the grid integration and consumption of intermittent energy sources such as wind and solar power. As the core carrier of energy storage systems, battery compartments (i.e., containerized energy storage units) have been widely adopted. Currently, battery compartment foundation types mainly include raft foundations, independent foundations, and strip foundations, with different design schemes adopted based on differences in geological conditions, load-bearing capacity, and seismic requirements in actual engineering projects.

[0003] Currently, energy storage power stations are trending towards centralized deployment at the GWh level. However, the traditional cast-in-place concrete foundation for battery compartments has a long construction cycle, high cost, and is difficult to dismantle. There is an urgent need to find a solution that can be quickly assembled and constructed. Utility Model Content

[0004] The purpose of this invention is to provide an integrated foundation for a prefabricated energy storage battery compartment firewall, which can solve the problems mentioned in the background art.

[0005] The technical solution of this utility model:

[0006] An integrated foundation for a prefabricated energy storage battery compartment firewall includes a prefabricated independent foundation and a prefabricated beam. A prefabricated connector is provided on the top of the prefabricated independent foundation. Several first sleeves are horizontally distributed inside the prefabricated connector. Each prefabricated connector has a first sleeve opening corresponding to the position of the first sleeve on its outer periphery. The protruding steel bars of the prefabricated beam pass through the first sleeve opening and connect to the first sleeve.

[0007] Several prefabricated independent foundations are connected to prefabricated beams through prefabricated connectors to form a battery compartment foundation, and a prefabricated firewall is installed on top of the battery compartment foundation.

[0008] Furthermore, the prefabricated firewall includes a prefabricated capping, prefabricated columns, and prefabricated wall panels. The prefabricated capping is fixedly connected to the top of the prefabricated columns by bolts, and the prefabricated columns and prefabricated wall panels are vertically spliced ​​by mortise and tenon joints.

[0009] The prefabricated column includes a core column, a middle column, and a side column. Connecting grooves are provided on all four sides of the core column, two opposing surfaces of the middle column, and one side of the side column.

[0010] The prefabricated wall panel includes two outer wall panels and an inner wall panel fixed between the two outer wall panels. The two ends of the inner wall panel extend beyond the two ends of the outer wall panels in the horizontal direction to form a tenon-and-mortise connection with the connecting groove. The lower ends of the two outer wall panels extend beyond the lower ends of the inner wall panel, and the upper ends of the inner wall panel extend beyond the upper ends of the two outer wall panels to form a tenon-and-mortise connection with other prefabricated wall panels.

[0011] Furthermore, the prefabricated connector is provided with a plurality of vertically distributed second sleeves, and the top of the prefabricated connector has a second sleeve opening corresponding to the position of the second sleeve; the bottom of the prefabricated column has a plurality of first longitudinal steel bars, which pass through the second sleeve opening and connect to the second sleeves.

[0012] Furthermore, the prefabricated independent foundation is connected to the prefabricated connector via a leveling and vibration isolation support; the leveling and vibration isolation support includes a lower metal plate fixed to the top of the prefabricated independent foundation, and the top middle of the lower metal plate is connected to the bottom of the upper metal plate via a vibration isolation layer.

[0013] Several steel springs are fixed to the top of the lower metal plate and the bottom of the upper metal plate. A third sleeve is provided between the upper and lower steel springs. The upper and lower ends of the third sleeve are fixedly connected to the upper and lower steel springs respectively. Holes corresponding to the positions of the third sleeves are opened on both the upper and lower metal plates. The bottom of the prefabricated connector has a third sleeve opening corresponding to the position of the second sleeve.

[0014] The top of the precast independent foundation has several second longitudinal steel bars, which pass through the holes in the lower metal plate, the third sleeve, the holes in the upper metal plate, the third sleeve opening, and are connected to the second sleeve in sequence.

[0015] Furthermore, the prefabricated connector has multiple layers of first sleeves, and each layer of first sleeves is arranged in a grid pattern.

[0016] Furthermore, the precast top has multiple first threaded holes that mate with bolts, the top of the precast column has multiple second threaded holes that mate with bolts, and the precast column has multiple bolt sleeves that mate with bolts.

[0017] Furthermore, the edge of the precast cap has drip lines.

[0018] Furthermore, the bottom of the drip line is coated with black topcoat.

[0019] Furthermore, a lead-core damper is embedded at the centroid of the vibration isolation layer.

[0020] Furthermore, the precast columns and exterior wall panels are made of materials with high strength, impact resistance, and weather resistance; the interior wall panels are made of materials with fireproof, heat-insulating, impact-resistant, and environmentally friendly properties.

[0021] The beneficial effects of this utility model are:

[0022] (1) Core components such as precast independent foundations, precast beams, precast connectors, precast capping, precast columns, and precast wall panels can all be produced in the factory in a standardized manner, achieving precise manufacturing and quality control, greatly shortening the construction cycle of the battery compartment foundation, and quickly responding to the grid connection needs of today's new energy.

[0023] (2) This utility model can flexibly adjust the arrangement of the battery compartment foundation according to the power / capacity level, battery compartment size and other configuration parameters of the energy storage power station, so as to achieve a precise match between project requirements and functional layout. Moreover, when the power station needs to be expanded in the later stage, there is no need to renovate and rebuild. Only independent foundations, beams and firewall modules need to be added in the reserved position or adjacent area of ​​the existing foundation. The "Lego-style" assembly process provides flexibility and space for energy storage projects, which is more in line with the phased construction of energy storage projects and adapts to the future updates and iterations of related technologies of energy storage power stations.

[0024] (3) The leveling and vibration isolation bearings installed on the independent foundation module can effectively isolate the seismic effect from the vibration generated by the operation of the battery compartment itself, thereby improving the stability of the system operation. Secondly, the leveling function can adjust the foundation depth of the battery compartment within a certain range according to the actual terrain and geological conditions of the site. The good terrain and geological adaptability greatly expands the site selection range of energy storage power stations and avoids the disadvantages of traditional cast-in-place foundations that require high-cost foundation pretreatment for special terrain and geological conditions.

[0025] (4) The building materials are easy to assemble, disassemble, and recyclable, which significantly reduces the negative impact of construction waste on the environment. This meets the "dual carbon" target and the requirements of green building, and can promote the power industry to gradually move towards low-carbon and environmentally friendly transformation.

[0026] (5) This utility model realizes the functional integration of firewall and battery compartment foundation, and constructs a prefabricated foundation system with adaptive leveling and vibration isolation capabilities, which supports flexible deployment on the construction site and meets the core development needs of the power industry for flexible capacity expansion and low-carbon construction of energy storage power stations.

[0027] In summary, the present utility model assembles prefabricated firewalls and shares battery compartment foundations to isolate and fire-retard surrounding battery compartments. The present utility model transforms the foundation of battery compartments of energy storage power stations from a static load-bearing type to a dynamically adaptive type. The prefabricated foundation modules of battery compartments can be quickly and flexibly assembled and arranged on site. While meeting the scale requirements of energy storage power stations of various levels, it has the adaptive functions of leveling and vibration isolation, shortens the construction period, allows recycling of building materials, and meets the current core demands of the power industry for rapid deployment, flexible expansion and low-carbon construction.

[0045] The present invention will be further described below with reference to the accompanying drawings.

[0046] like Figures 1-16 As shown, this utility model provides a first embodiment of an integrated foundation for a prefabricated energy storage battery compartment firewall, including a prefabricated independent foundation 1 and a prefabricated beam 2. A prefabricated connector 3 is provided on the top of the prefabricated independent foundation 1. Several horizontally distributed first sleeves 31 are provided inside the prefabricated connector 3. The outer periphery of the prefabricated connector 3 has a first sleeve opening corresponding to the position of the first sleeve 31. The outwardly extending steel bar 21 of the prefabricated beam 2 passes through the first sleeve opening and connects to the first sleeve 31.

[0047] Several prefabricated independent foundations 1 are connected to prefabricated beams 2 through prefabricated connectors 3 to form a battery compartment foundation. A prefabricated firewall 4 is provided on the top of the battery compartment foundation to isolate and retard the surrounding battery compartment.

[0048] In this embodiment, the precast independent foundation 1 can be replaced by a precast strip foundation, raft foundation, etc.

[0049] In this embodiment, the prefabricated firewall 4 is cross-shaped. There are nine prefabricated independent foundations 1, arranged in three rows of three. The two prefabricated independent foundations 1 are connected by prefabricated connectors 3 and prefabricated beams 2 to form a grid-shaped battery compartment foundation. The cross-shaped prefabricated firewall 4 is connected to the top of the battery compartment foundation to form an integrated foundation for the battery compartment and firewall.

[0050] In this embodiment, after the protruding steel bars 21 of the precast beam 2 are inserted into the first sleeve 31, high-strength non-shrink grout is poured into the gap between the first sleeve 31 and the protruding steel bars 21 of the precast beam 2 to connect and fix the two.

[0051] In this embodiment, the prefabricated connector 3 also has several stirrups, which are interspersed with the first sleeve 31 in layers, and form a block after concrete is poured in the middle.

[0052] Based on the first embodiment, this utility model provides a second embodiment of an integrated foundation for a prefabricated energy storage battery compartment firewall. The prefabricated firewall 4 includes a prefabricated capping 41, prefabricated columns 43, and prefabricated wall panels 42. The prefabricated capping 41 is fixedly connected to the top of the prefabricated columns 43 by bolts, and the prefabricated columns 43 and the prefabricated wall panels 42 are vertically spliced ​​by mortise and tenon joints.

[0053] The prefabricated column 43 includes a core column 431, a middle column 432 and a side column 433. The four sides of the core column 431, two opposing surfaces of the middle column 432 and one side of the side column 433 are provided with connecting grooves 434.

[0054] The prefabricated wall panel 42 includes two outer wall panels 421 and an inner wall panel 422 fixed between the two outer wall panels 421. The two ends of the inner wall panel 422 in the horizontal direction extend beyond the two ends of the outer wall panels 421 to form a tenon-and-mortise connection with the connecting groove 434. The lower ends of the two outer wall panels 421 extend beyond the lower ends of the inner wall panel 422, and the upper ends of the inner wall panel 422 extend beyond the upper ends of the two outer wall panels 421 to form a tenon-and-mortise connection with other prefabricated wall panels 42.

[0055] Since the lower ends of the two outer wall panels 421 extend beyond the lower end of the inner wall panel 422, a gap is formed between the lower ends of the two outer wall panels 421 and the lower end of the inner wall panel 422, allowing the upper ends of the inner wall panels 422 of other prefabricated wall panels 42 to be inserted, forming a mortise and tenon connection.

[0056] In this embodiment, prefabricated wall panels 42 are arranged longitudinally between two prefabricated columns 43 using mortise and tenon joints to form a cross-shaped wall structure. Finally, a prefabricated capping 41 is bolted to the top surface of the prefabricated columns 43. The gap between the prefabricated capping 41 and the bolts is sealed and smoothed with fire-retardant silicone structural adhesive. Similarly, the gap between the prefabricated capping 41 and the top prefabricated wall panel 42 is filled with fire-retardant silicone structural adhesive, forming a prefabricated fire wall 4. The upper end of the inner wall panel 422 of the top prefabricated wall panel 42 is flush with the upper end of the outer wall panel 421, and the lower end of the inner wall panel 422 of the bottom prefabricated wall panel 42 is flush with the lower end of the outer wall panel 421.

[0057] Based on any of the above embodiments, this utility model provides a third embodiment of an integrated prefabricated energy storage battery compartment firewall foundation. The prefabricated connector 3 is provided with a plurality of vertically distributed second sleeves 33. The top of the prefabricated connector 3 has a second sleeve opening corresponding to the position of the second sleeve 33. The bottom of the prefabricated column 43 has a plurality of first longitudinal steel bars 435. The first longitudinal steel bars 435 pass through the second sleeve opening and connect to the second sleeve 33, which facilitates the connection between the prefabricated connector 3 and the prefabricated column 43.

[0058] In this embodiment, after the first longitudinal steel bar 435 is inserted into the second sleeve 33, high-strength non-shrink grout is injected into the gap between the second sleeve 33 and the first longitudinal steel bar 435 to connect and fix the two.

[0059] Based on the third embodiment, this utility model provides a fourth embodiment of the prefabricated energy storage battery compartment firewall integrated foundation, wherein the prefabricated independent foundation 1 is connected to the prefabricated connector 3 via a leveling and vibration isolation support 5; the leveling and vibration isolation support 5 includes a lower metal plate 51 fixed to the top of the prefabricated independent foundation 1, and the top middle of the lower metal plate 51 is connected to the bottom of the upper metal plate 53 via a vibration isolation layer 52.

[0060] The leveling and vibration isolation bearing 5 has both vibration isolation and leveling functions. The vibration isolation function can effectively isolate the seismic effect from the vibration generated by the operation of the battery compartment itself, thereby improving the stability of the system operation. Secondly, the leveling function can adjust the foundation depth of the battery compartment within a certain range according to the actual topography and geological conditions of the site.

[0061] Several steel springs 54 are fixed to the top of the lower metal plate 51 and the bottom of the upper metal plate 53. A third sleeve 55 is provided between two upper and lower steel springs 54. The upper and lower ends of the third sleeve 55 are fixedly connected to the upper and lower steel springs 54 respectively. Holes 56 corresponding to the positions of the third sleeve 55 are opened on both the upper metal plate 53 and the lower metal plate 51. The bottom of the prefabricated connector 3 has a third sleeve opening corresponding to the position of the second sleeve 33.

[0062] The top of the prefabricated independent foundation has several second longitudinal steel bars 11, which pass through the holes 56 of the lower metal plate 51, the third sleeve 55, the holes 56 of the upper metal plate 53, the third sleeve opening, and are connected to the second sleeve 33.

[0063] In this embodiment, after the second longitudinal steel bar 11 is inserted into the second sleeve 33, high-strength non-shrink grout is injected into the gap between the second sleeve 33 and the second longitudinal steel bar 11, and into the gap between the third sleeve 55 and the second longitudinal steel bar 11 to connect and fix the two.

[0064] In this embodiment, the vibration isolation layer 52 is constructed by alternating layers of steel plates and rubber sheets bonded together by vulcanization, with a lead-core damper pressed into its centroid. The vibration isolation function is mainly achieved by the vibration isolation layer, which serves as the main vibration isolation element and is responsible for dissipating most of the vibration energy. The steel springs 54 arranged around the vibration isolation layer 52 serve as auxiliary elements, working in conjunction with the vibration isolation layer 52 to further absorb the remaining vibration.

[0065] In this embodiment, the leveling function is implemented in the following two ways:

[0066] Scenario 1: After the precast independent foundation 1 is hoisted and placed on site, the third sleeve 55 and hole 56 of the leveling and vibration isolation support 5 are inserted into the second longitudinal steel bar 11. In this process, if there are boulders or hard rocks in the foundation at the bottom of the precast independent foundation 1, the geological layers such as rocks may be difficult to level due to limited construction conditions (lack of construction equipment, insufficient construction period, etc.), resulting in tilting or excessive height.

[0067] If tilting occurs, first adjust the higher side of the upper metal plate 53 to compress the steel spring 54 on the higher side and stretch the one on the lower side, thereby correcting the upper metal plate 53 to a horizontal state. Then, pour high-strength non-shrink grout to fix the second longitudinal steel bar 11 and the third sleeve 55.

[0068] If the precast independent foundation 1 is too high, the upper metal plate 53 can be adjusted first to compress all the steel springs 54 and lower the height of the upper metal plate 53. Then, high-strength non-shrink grout can be poured to fix the second longitudinal steel bar 11 and the third sleeve 55.

[0069] Scenario 2: If there are significant errors during on-site construction, rectification will require a lot of time and building materials. The same process described above will be used to achieve the leveling function.

[0070] Based on any of the above embodiments, this utility model provides a fifth embodiment of an integrated foundation for a prefabricated energy storage battery compartment firewall. The prefabricated connector 3 has multiple layers of first sleeves 31, and each layer of first sleeves 31 is arranged in a grid pattern, which facilitates connection with the outward reinforcing bars 21 of the prefabricated beams 2 in different directions.

[0071] Based on the second embodiment, this utility model provides a sixth embodiment of an integrated prefabricated energy storage battery compartment firewall foundation. The prefabricated cap 41 has multiple first threaded holes 411 that mate with bolts, and the top of the prefabricated column 43 has multiple second threaded holes 436 that mate with bolts. The prefabricated column 43 contains multiple bolt sleeves 437 that mate with bolts. The bolts engaging with the first threaded holes 411, second threaded holes 436, and bolt sleeves 437 facilitate the assembly and disassembly of the prefabricated cap 41. The second threaded holes 436 and bolt sleeves 437 can also be used for hoisting.

[0072] Based on the second or sixth embodiment, this utility model provides a seventh embodiment of an integrated foundation for a prefabricated energy storage battery compartment firewall, wherein the edge of the prefabricated cap 41 has drip lines 412 that can collect and guide rainwater droplets.

[0073] Based on the seventh embodiment, this utility model provides an eighth embodiment of the integrated foundation for the prefabricated energy storage battery compartment firewall. The bottom of the drip line 412 is coated with black topcoat in order to enhance the visual recognition of the outline and improve the stain resistance of the rainwater collection area by using dark paint, thus combining aesthetics and practicality.

[0074] Based on the fourth embodiment, this utility model provides a ninth embodiment of an integrated foundation for a prefabricated energy storage battery compartment firewall, wherein a lead-core damper is embedded at the centroid of the vibration isolation layer 52, which can dissipate the vibration energy input to the structure through plastic deformation.

[0075] Based on the second embodiment, this utility model provides a tenth embodiment of an integrated fireproof foundation for a prefabricated energy storage battery compartment. The prefabricated columns 43 and the outer wall panels 421 are made of materials with high strength, impact resistance, and weather resistance, such as high-performance concrete (HPC) and ultra-high-performance concrete (UHPC), but not limited to these. The inner wall panels 422 are made of materials with fireproof, heat-insulating, impact-resistant, and environmentally friendly properties, such as calcium silicate board and magnesium crystal fireproof board, but not limited to these.

[0076] The above description is only a preferred embodiment of the present utility model and should not be construed as a limitation of this application. All equivalent changes and modifications made within the scope of the patent application of the present utility model should be included in the scope of the present utility model.
