Description

Technical Field

[0001] This utility model relates to the field of energy storage equipment technology, and in particular to an assemblable and movable energy storage compartment based on UHPC, for accommodating battery modules, power electronic equipment, etc. Background Technology

[0002] With the rapid development of the new energy industry, the demand for electrochemical energy storage power stations has increased dramatically. As the core unit that centrally houses key equipment such as battery systems, converters (PCS), and energy management systems (EMS), the performance of the energy storage compartment directly affects the safety, lifespan, and reliability of the entire energy storage system.

[0003] Currently, the following materials are commonly used for the enclosure structures (walls and roof) of energy storage cells on the market:

[0004] 1. Color steel plate: Low cost and light weight, but low fire resistance (usually below Class A), average thermal insulation performance, poor corrosion resistance, and easy to deform and be damaged in extreme weather (such as hurricanes and hail).

[0005] 2. Fiberglass sheet: It has good corrosion resistance, but extremely poor fire resistance (it is flammable and produces a lot of toxic fumes when burning), limited strength, and weak impact resistance.

[0006] 3. Metal sandwich panels (such as rock wool sandwich panels): Fire resistance is improved (up to Class A), and thermal insulation is good, but they have problems such as many seams, sealing depends on construction techniques, poor overall integrity, and heavy weight. After long-term use, the metal panels are still at risk of corrosion, affecting aesthetics and lifespan.

[0007] The risk of thermal runaway of batteries inside the energy storage compartment is a core safety concern. Traditional enclosure structures are ill-suited to effectively prevent the spread of flames and high temperatures in the event of an internal fire, potentially leading to catastrophic consequences. Furthermore, energy storage compartments are typically deployed in harsh outdoor environments, requiring enclosure structures with extremely high durability, impact resistance, and weather resistance. Utility Model Content

[0008] The purpose of this utility model is to provide a technical solution for an assemblable and mobile energy storage compartment based on UHPC to address the shortcomings of existing technologies. This solution not only enables the energy storage compartment to have fireproof and explosion-proof functions, improving safety, but also has excellent corrosion resistance and salt spray resistance. The dustproof and waterproof rating of the compartment can reach IP66, and it also has good durability and all-weather adaptability, which can extend the service life of the energy storage compartment. At the same time, its structural integrity and sealing are good, which can shorten the construction cycle and reduce costs.

[0009] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0010] A UHPC-based, assembleable, and mobile energy storage module includes:

[0011] Frame structure;

[0012] The building envelope includes wall panels and a roof layer, with the roof layer consisting of several roof panels spliced ​​together.

[0013] Base plate;

[0014] The door, wall panels, roof panels, floor panels, and door are all connected to the cabin frame;

[0015] Its features are:

[0016] The wall panels, roof panels, and doors are all constructed from UHPC sheets. This structural design not only provides the energy storage compartment with fire and explosion protection, enhancing safety, but also offers excellent corrosion resistance and salt spray resistance. The compartment boasts an IP66 dust and water resistance rating, along with good durability and all-weather adaptability, extending its service life. Furthermore, its excellent structural integrity and sealing shorten construction time and reduce costs.

[0017] Furthermore, the wall panels, roof panels, and doors are all made of UHPC sheets spliced ​​together or cast in one piece.

[0018] Furthermore, the UHPC sheet includes a sheet body and a UHPC frame. The UHPC frame is spliced ​​to form a regular shape, and the sheet body is fixedly connected within the regular shape.

[0019] Furthermore, the splicing edges of the UHPC sheets are equipped with tongue-and-groove or stepped interfaces to connect adjacent UHPC sheets, ensuring the sealing and integrity of the splicing gaps.

[0020] Furthermore, both tongue-and-groove and stepped-type interfaces are filled with sealing material at their joints.

[0021] Furthermore, a fastener is provided at the connection point of the stepped interface for fixed connection between two adjacent UHPC boards.

[0022] Furthermore, the UHPC sheet is fixedly connected to the cabin frame via connectors, and the connection between the cabin frame and the UHPC sheet is filled with sealant.

[0023] Furthermore, the cabin frame includes columns and horizontal beams, both of which are made of steel sections spliced ​​together, or both of which are made of reinforced concrete components or reinforced UHPC components cast together.

[0024] Furthermore, the UHPC sheet has a composite sandwich structure. This composite sandwich structure can be achieved through a single molding process or multiple bonding processes, integrating structure, temperature control, and fire resistance. The UHPC sheet comprises an inner panel, a core panel, and an outer panel arranged sequentially from the inside out.

[0025] Furthermore, the thickness of the inner panel is 5-100mm, and the thickness of the outer panel is 5-100mm, to meet the energy storage compartment's requirements for different temperatures and strengths.

[0026] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0027] 1. This utility model is safe and reliable, and has fireproof and explosion-proof functions: UHPC is an A1 grade non-combustible material. It adopts a composite structure of UHPC surface layer and A grade or B1 grade thermal insulation core layer to form an efficient barrier against fire and high temperature spread, which greatly improves the fire safety of the energy storage compartment. The high toughness of UHPC makes it not easy to break under the slight explosion impact caused by battery thermal runaway, and can effectively contain the impact of the accident.

[0028] 2. This utility model has excellent corrosion resistance, salt spray resistance, durability and all-weather adaptability: UHPC has extremely low permeability and excellent resistance to freeze-thaw, carbonization and chloride ion erosion. Its acid and alkali resistance and corrosion resistance are far superior to metal materials. It can easily cope with harsh environments such as salt spray, humidity, rain and snow, and ultraviolet rays, extend its service life and require no or little maintenance.

[0029] 3. This utility model has high strength and high toughness, and excellent impact resistance: UHPC has extremely high strength and toughness, which enables it to withstand accidental collisions, hail, flying stones and other impacts, protecting the internal core equipment.

[0030] 4. The present invention has excellent thermal performance: through the composite insulation layer design, it can achieve high thermal insulation performance (low K value), reduce the energy consumption of temperature control in the cabin, provide a more stable and suitable working environment for the battery system, and extend the battery life.

[0031] 5. The present invention has good structural integrity and sealing performance: large-size prefabricated panels can reduce the number of joints, and the airtightness and watertightness of the cabin are ensured through interface design and sealing treatment, effectively preventing dust, moisture and corrosion.

[0032] 6. This utility model is easy to industrialize and has controllable quality: UHPC panels are prefabricated in the factory, with stable quality, accurate dimensions, fast on-site installation, short construction period, and overall cost-effectiveness compared to traditional methods that require multiple constructions.

[0054] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0055] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0056] like Figure 1 As shown, this utility model discloses an assemblable and movable energy storage cabin based on UHPC, comprising: cabin frame 1, enclosure structure, bottom plate 4, and door 5.

[0057] The enclosure structure includes wall panels 2 and roof layer 3, which is composed of several roof panels 301 spliced ​​together.

[0058] Wall panel 2, roof panel 301, floor panel 4 and door 5 are all connected to cabin frame 1.

[0059] Wall panel 2, roof panel 301 and door 5 are all made of UHPC sheet material.

[0060] Preferably, the wall panel 2, the roof panel 301, and the door 5 are all made of UHPC sheet splicing or integral casting.

[0061] UHPC sheets consist of a sheet body and UHPC frames. The UHPC frames are spliced ​​together to form a regular shape, and the sheet body is fixedly connected within the regular shape. This regular shape can be rectangular or polygonal.

[0062] UHPC sheets have a composite sandwich structure. The composite sandwich structure can be formed by one-time molding or multiple bonding processes, achieving integration of structure, temperature, and fire resistance.

[0063] UHPC sheet material includes an inner panel 509, a core panel 508, and an outer panel 507 arranged sequentially from the inside out.

[0064] The core board 508 is filled with heat-insulating and fire-resistant filler 303.

[0065] The heat-insulating and fire-resistant filler 303 is one or more of rock wool, glass wool, rigid polyurethane foam and aerogel felt.

[0066] The inner panel 509 is made of one or more of the following materials: UHPC board, fiber cement board, magnesium oxide board, gypsum board, calcium silicate board, and ceramic board, serving to protect, insulate, and decorate the interior.

[0067] The outer panel 507 is one or more of the following: UHPC board, fiber cement board, magnesium oxide board, gypsum board, calcium silicate board, and ceramic board. UHPC board is preferred for the outer panel 507, as it provides load-bearing capacity, impact resistance, weather resistance, and corrosion protection.

Their compressive strength can reach over 150 MPa, and their flexural strength can reach over 30 MPa. UHPC panels are made of a concrete matrix, fibers, and a skeleton, which improves the overall strength and stability of the UHPC panel.

[0069] The outer panel 507 has a decorative surface layer or a functional coating on its outer side. The outer panel 507 can be shaped, polished, have exposed aggregate, or have a fair-faced concrete effect, or be coated with a plum blossom paint.

[0070] The thickness of the inner panel 509 is 5-100mm, and the thickness of the outer panel 507 is 5-100mm, which meets the requirements of the energy storage compartment for different temperatures and strengths.

[0071] The splicing edges of UHPC sheets are equipped with tongue and groove or stepped joints to connect adjacent UHPC sheets, ensuring the sealing and integrity of the splicing gaps.

[0072] UHPC sheets can be pre-embedded with pipeline channels, lifting components, or installation accessories (such as pre-embedded nuts for internal mounting brackets) to achieve structural and functional integration.

[0073] like Figure 2 The diagram shows the splicing of roof layer 3. Adjacent roof panels 301 can be connected via... Figure 3 The tongue-and-groove interface shown.

[0074] The roof panel 301 includes an inner panel 509, a core panel 508, an outer panel 507, and a second UHPC frame 310. The core panel 508 uses a heat-insulating and fire-resistant filler 303, preferably rock wool. Both the inner panel 509 and the outer panel 507 are made of UHPC board. Together, the inner panel 509 and the outer panel 507 constitute a UHPC integrated heat-insulating and fire-resistant panel 302, with rock wool filling the UHPC integrated heat-insulating and fire-resistant panel 302.

[0075] The second UHPC frame 310 is spliced ​​to form a rectangular structure. The inner panel 509, core panel 508, and outer panel 507 are located inside the rectangular structure. The end face of the second UHPC frame 310 is connected to a vertically arranged second connecting part 305 through a horizontally arranged first connecting part 304. The first connecting part 304, the second connecting part 305, and the end face of the second UHPC frame 310 cooperate to form a cavity 306 with an opening. When two adjacent roof panels 301 are spliced, the end face of the second UHPC frame 310 of one roof panel 301 approaches the second connecting part 305 of the other roof panel 301, forming a gap. The gap connects to the cavity 306. At least one cavity 306 is provided with a leak-proof pipe 307. The gap is filled with a sealing material 203, which includes a first sealing strip 309. The first sealing strip 309 is preferably silicone sealant. The gap is filled with a heat-insulating and fire-retardant strip 308 inside the first sealing strip 309.

[0076] The following can also be used between two adjacent roof panels 301: Figure 4 The stepped interface connection is shown.

[0077] The roof panel 301 includes an inner panel 509, a core panel 508, an outer panel 507, and a second UHPC frame 310. The core panel 508 uses a heat-insulating and fire-resistant filler 303, preferably rock wool. Both the inner panel 509 and the outer panel 507 are made of UHPC board. Together, the inner panel 509 and the outer panel 507 constitute a UHPC integrated heat-insulating and fire-resistant panel 302, with rock wool filling the UHPC integrated heat-insulating and fire-resistant panel 302.

[0078] The second UHPC frame 310 is spliced ​​to form a rectangular structure. The inner panel 509, core panel 508, and outer panel 507 are located inside the rectangular structure. A groove 311 is provided on one side of each of the second UHPC frame 310. When two adjacent roof panels 301 are spliced, the end face of the second UHPC frame 310 of one roof panel 301 approaches the second UHPC frame 310 of the other roof panel 301, forming a gap. The gap is filled with a sealant 203, which includes a first sealant and a waterproof membrane 314. The first sealant is preferably a silicone sealant, and the waterproof membrane 314 can be an EPDM rubber waterproof membrane 314. A heat-insulating and fire-retardant strip 308 is filled between the first sealant and the waterproof membrane 314 in the gap.

[0079] The stepped interface is equipped with a fastener for fixing the connection between two adjacent UHPC boards.

[0080] The fasteners include a cover plate 312 and a third self-tapping screw 313. The cover plate 312 is fastened to the two second UHPC frames 310. The edge of the cover plate 312 is embedded in the groove 311. The third self-tapping screw 313 passes through the cover plate 312 and connects to the second UHPC frame 310, thereby achieving a fixed assembly between two adjacent roof panels 301.

[0081] The UHPC sheet is fixedly connected to the cabin frame 1 by connectors, and the connection between the cabin frame 1 and the UHPC sheet is filled with sealant 203.

[0082] The cabin frame 1 includes columns and horizontal beams, preferably steel columns 102 and steel beams 101. Both columns and beams are constructed from spliced ​​steel sections, which can be I-beams. Alternatively, both columns and beams can be cast from reinforced concrete components or reinforced UHPC components. Reinforced concrete components refer to structural members in which steel bars are embedded to enhance the load-bearing capacity. The core principle is that the steel bars and concrete form a unified whole through bond, jointly bearing the load, thus preserving the compressive strength of concrete while increasing tensile strength through the steel bars. Reinforced UHPC components refer to UHPC slabs with added steel bars to improve the strength and stability of the cabin frame 1.

[0083] The cross-sectional shape of the column is at least one of rectangular, L-shaped, T-shaped, H-shaped, O-shaped and Y-shaped, and the cross-sectional shape of the horizontal beam is at least one of rectangular, I-shaped, L-shaped, T-shaped, H-shaped, O-shaped and Y-shaped.

[0084] like Figure 5 and Figure 6 As shown, when the roof panel 301 is connected to the steel beam 101, an L-shaped connector 103 is selected as the connector. One side of the L-shaped connector 103 is connected to the second UHPC frame 310 by a first self-tapping screw 104, and the other side abuts against the steel beam 101.

[0085] like Figure 7 and Figure 8 As shown, the door 5 includes a panel, a third UHPC frame 502, a first crossbeam 501, and a second sealing strip 506. The first crossbeam 501 is connected to the inner side of the third UHPC frame 502. The panel is located within the space enclosed by the first crossbeam 501 and the third UHPC frame 502. The second sealing strip 506 is located on the outer side of the third UHPC frame 502. The second sealing strip 506 can be made of EPDM rubber. A steel hinge 504 is provided on the third UHPC frame 502, and the third UHPC frame 502 is connected to the cabin frame 1 via a steel door lock 505.

[0086] like Figures 9 to 11 As shown, the wall panel 2 is connected between the steel beam 101 and the steel column 102. The wall panel 2 includes a panel body, a second crossbeam 201, a first UHPC frame 202, and a sealing material 203. The first UHPC frame 202 is spliced ​​to form a rectangular structure. The second crossbeam 201 is connected to the inner side of the first UHPC frame 202. The panel body is located in the space enclosed by the second crossbeam 201 and the first UHPC frame 202. The sealing material 203 is located on the outer side of the first UHPC frame 202.

[0087] like Figure 12 As shown, when the top of the wall panel 2 is connected to the steel beam 101, the panel is connected to the steel beam 101 through the first UHPC frame 202. The space between the first UHPC frame 202 and the steel beam 101 is filled with a sealant 203, which includes caulking agent, PU foam and PE rod to improve the sealing effect. A connecting steel plate 204 is provided between one end face of the first UHPC frame 202 and the sealant 203. The connecting steel plate 204 is connected to the first UHPC frame 202 through the second self-tapping screw 205.

[0088] like Figure 13 As shown, when the side of the wall panel 2 is connected to the steel column 102, the panel is connected to the steel column 102 through the first UHPC frame 202. The space between the first UHPC frame 202 and the steel column 102 is filled with a sealant 203, which includes caulking agent, PU foam and PE rod to improve the sealing effect. A connecting steel plate 204 is provided between one end face of the first UHPC frame 202 and the sealant 203. The connecting steel plate 204 is connected to the first UHPC frame 202 through the second self-tapping screw 205.

[0089] like Figure 14As shown, when the bottom of the wall panel 2 is connected to the steel beam 101, the panel is connected to the steel beam 101 through the first UHPC frame 202. The space between the first UHPC frame 202 and the steel beam 101 is filled with a sealant 203, which includes caulking agent and cement mortar to improve the sealing effect. A connecting steel plate 204 is provided between one end face of the first UHPC frame 202 and the sealant 203.
