Description

Technical Field

[0001] This utility model relates to the field of battery energy storage equipment technology, and in particular to a fire-fighting pipeline system and an energy storage container. Background Technology

[0002] In overseas energy storage projects, there are extremely strict requirements on the weight of the storage compartments during transportation; exceeding the weight limit significantly increases transportation costs. Therefore, modular storage compartments are increasingly being adopted. However, water fire suppression systems typically require prefabrication and installation as a whole, and the compartment is fully assembled during transportation, making disassembly impossible. This severely limits the development of modular storage compartments. Currently, modular water piping is generally installed on the top of the compartment. However, this installation method not only affects the compartment's protection level but also requires working at height, posing a risk of personnel falling. Furthermore, this installation method presents high risks in terms of transportation timelines and requires extensive on-site work, resulting in higher costs.

[0003] To address the above issues, a fire-fighting pipeline system and an energy storage container are proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a fire-fighting pipeline system and an energy storage container, which have the advantages of being easy to disassemble and transport, and reducing installation risks and costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A plurality of second pipelines are detachably connected to the first pipeline, and the second pipelines are fixed on the inner wall of the container body. One end of the second pipeline away from the first pipeline opens into the interior of the container body.

[0007] According to the fire protection piping system of this utility model embodiment, the pre-installed piping system reduces the amount of on-site installation work and lowers construction costs. The detachable connection method ensures the integrity of fire protection functions while meeting the weight limit requirements for transportation.

[0008] In addition, the fire-fighting piping system according to the above embodiments of this utility model may also have the following additional technical features:

[0025] The following description, in conjunction with the accompanying drawings, provides a more detailed account of a fire-fighting piping system and an energy storage container according to the present invention. Preferred embodiments of the present invention are shown. It should be understood that those skilled in the art can modify the present invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the present invention.

[0026] In the description of this specification, terms such as "one embodiment" or "some embodiments" mean that one or more embodiments of this specification include a particular feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0027] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0028] In existing technologies, when energy storage containers adopt a modular design, the fire protection piping system is usually prefabricated and installed as a whole. This results in the container being fully assembled and unable to be disassembled during transportation, leading to increased costs due to overweight transport. Current solutions install the modular water piping on the top of the container exterior. This arrangement compromises the container's sealing structure, reducing its protection level. Installation and maintenance require working at height, increasing the risk of falls. Furthermore, external piping causes the transport height to exceed limits, and on-site installation requires significant manpower and resources.

[0029] To address these issues, designers discovered a fundamental contradiction between the traditional non-removable structure of fire-fighting piping and the need for lightweight transportation. Furthermore, the top-mounted installation method presented multiple technical obstacles. Analysis revealed that placing the main water supply path at the bottom of the support structure could circumvent height restrictions during transport, while a segmented piping design allowed for flexible switching between transport and operational modes. Further consideration was given to maximizing the use of internal space, integrating the fire extinguishing medium delivery terminal into the inner wall of the enclosure, maintaining the protection level while achieving precise fire suppression coverage.

[0030] Therefore, this utility model proposes a fire-fighting piping system suitable for energy storage containers. The fire-fighting piping system according to an embodiment of this utility model is described below with reference to the accompanying drawings.

[0031] According to the fire protection piping system of the present utility model embodiment, such as Figure 1 , Figure 2 As shown, including along the first direction (e.g.) Figure 1 The system includes a first pipe 1 (shown in the Y direction) extending and installed at the bottom of the support, a water supply pipe 3 fixed to the side wall of the housing and communicating with the external environment, and a second pipe 2 detachably connected to the first pipe 1 and fixed to the inner wall of the housing. One end of the water supply pipe 3 is connected to the first pipe 1, and the other end leads to the outside; multiple second pipes 2 are detachably connected to the first pipe 1, with their end openings facing the inside of the housing.

[0032] The support base refers to the foundation area of ​​the energy storage container's load-bearing structure, which can be achieved using a welded steel channel frame to provide a stable installation foundation for the first pipeline 1. The first directional extension refers to the pipeline being arranged along the length of the container, which can be achieved by segmenting and splicing straight metal pipes to accommodate the size requirements of different container specifications. The detachable connection refers to the use of quick-connect couplings between pipelines, which can be achieved using flanges and sealing rings, facilitating pipeline separation during transportation and reducing overall weight. The fixing to the inner wall of the container refers to the pipeline being connected to the internal support structure of the compartment via clamps, which can be achieved using pre-embedded mounting bases and bolt fastening to ensure the pipeline remains stable during transport.

[0033] Specifically, the first pipeline 1 is laid along the length of the container on the bottom metal frame of the support, forming an integral structure with the support through the rigid connector 7. The water supply pipe 3 is vertically connected to the end of the first pipeline 1 and extends to the outside of the container side wall, forming an external water source inlet port. The second pipeline 2 is connected to the first pipeline 1 through a quick-release connector, and extends upward along the inner wall of the container to the equipment installation area, with its end opening facing the battery module arrangement direction. In the transportation state, the second pipeline 2 can be separated from the first pipeline 1 and stored separately, reducing the overall weight of the container to the transportation standard; after arriving at the installation site, the integrity of the pipeline system is restored through the quick-connect device, at which point the end opening of the second pipeline 2 is directly aligned with the equipment inside the container, ensuring accurate coverage of the fire extinguishing medium.

[0034] Compared to existing technologies, traditional methods of installing fire-fighting main pipelines on top of containers require scaffolding for high-altitude installation, and the external pipelines disrupt the sealing structure of the container top. This invention places the first pipeline 1 at the bottom of the support frame, fully utilizing the redundant space at the bottom of the container and avoiding impact on the protective structure of the container top. The design of the first pipeline 1 and the detachable second pipeline 2 reduces the weight of the container during transportation, meeting the requirements for modular transport. Specifically, the first pipeline 1 is pre-installed on the support frame, and the second pipeline 2 is pre-installed inside the modular container. During transportation, the modular container can be disassembled and transported. Upon arrival at the designated location, the modular container is reassembled, and the detachable first pipeline 1 and second pipeline 2 are also assembled to form a complete fire-fighting pipeline system, reducing the cumbersome installation process.

[0035] Through the above technical solution, this utility model eliminates the safety hazards of high-altitude operations, reduces the installation and maintenance operation height to within 1.5 meters of the ground, maintains the complete and sealed structure of the box, and maintains the protection level of IP54 standard; the on-site installation time is shortened to within 2 hours, which reduces the amount of on-site construction compared with the traditional solution.

[0036] In some embodiments of this utility model, such as Figure 1 , Figure 2 As shown, it also includes a connecting pipe 4. The first pipe 1 is provided with multiple first water outlets (not shown in the figure), and multiple second pipes 2 are sequentially connected to the first water outlets through the connecting pipe 4.

[0037] The connecting pipe 4 refers to the pipe component used to branch and connect the second pipe 2 to the first pipe 1. Specifically, it can be implemented using a flexible hose with a quick-release connector. The quick-release connector allows the second pipe 2 to be quickly separated from the connecting pipe 4 during transportation, thereby reducing the overall weight of the cabin.

[0038] The first outlet refers to the water outlet interface that is spaced apart along the length of the first pipeline 1. Specifically, it can be achieved by opening a hole in the pipe wall with internal threads. The internal threads can match the external thread structure of the connecting pipeline 4, thereby enabling multiple second pipelines 2 to be flexibly disassembled as needed before transportation, reducing the amount of fixed installation of redundant pipelines.

[0039] Specifically, the first pipeline 1 serves as the main water supply pipeline, laid at the bottom of the support frame, with multiple first water outlets spaced apart along its extension direction. During transportation, the second pipeline 2 is separated from the connecting pipeline 4, retaining only the first pipeline 1 and the water supply pipe 3 as the basic structure, thereby reducing the weight of the enclosure. Upon arrival at the installation site, the second pipeline 2 is sequentially connected to the corresponding first water outlets via the connecting pipeline 4, forming branch fire-fighting pipelines. The threaded connection between the connecting pipeline 4 and the first water outlets eliminates the need for working at heights, allowing operators to assemble the pipelines on the ground and avoiding the risk of falls. The modular, split-connection structure allows the number and location of the second pipeline 2 to be adjusted according to actual fire-fighting needs, ensuring fire coverage while avoiding the disassembly limitations associated with prefabrication.

[0040] Compared to existing technologies, conventional split-type water pipelines are typically prefabricated as a single unit on the top of the cabin exterior. This makes them impossible to disassemble during transport, leading to excessive cabin weight, and requires high-altitude work during installation. This invention, through the design of the detachable connecting pipe 4, allows the second pipe 2 to be transported separately from the main water supply pipe, effectively controlling the cabin weight. The layout of the first outlet along the main water supply pipe allows branch pipes to select the optimal connection point based on site conditions, eliminating the need for centralized piping on the top of the cabin exterior, thus maintaining the protection level while reducing installation height.

[0041] Through the above technical solution, this utility model solves the problem of excessive weight during transportation caused by the overall prefabrication of fire-fighting pipelines in split-type cabins. The modular transportation of pipelines is achieved through a detachable connection structure, ensuring the cabin weight meets transportation weight limits. The design of the connecting pipeline 4 in conjunction with the first water outlet reduces the amount of on-site work requiring climbing, allowing operators to assemble the pipelines from the ground, thus reducing safety risks. The flexible configuration of branch pipelines avoids the prefabrication and installation of redundant pipelines, effectively controlling material costs.

[0042] In some embodiments of this utility model, such as Figure 1 , Figure 2 As shown, it also includes a spray element 5, which is connected to a port of the second pipeline 2 away from the first pipeline 1.

[0043] The spray component 5 refers to a device used to disperse and spray the extinguishing medium into the interior of the container. Specifically, it can be implemented using an atomizing nozzle or a high-pressure nozzle. The spray component 5 is connected to the second pipeline 2 via a detachable threaded interface or a snap-fit ​​structure. This detachable connection method allows the spray component 5 to be stored separately from the second pipeline 2 during transportation, eliminating the impact of the spray assembly on the total weight of the container during transportation.

[0044] Wherein, the end of the second pipeline 2 away from the first pipeline 1 refers to the end of the pipeline located on the inner wall of the box and open towards the inside of the box. Specifically, it can be implemented by a straight or elbow-type pipe structure. This end is quickly connected to the spray component 5 through on-site assembly, avoiding the overloading of the cabin due to the premature installation of the spray component during the transportation stage.

[0045] Specifically, during transportation, the second pipeline 2 and the first pipeline 1 remain detachable via the connecting pipeline 4, and the spray component 5 is stored independently in a packaging container outside the housing. Once the housing arrives at the installation site, the spray component 5 is directly assembled to the end port of the second pipeline 2 using threads or snap-fit ​​structures, forming a complete fire extinguishing medium delivery path. Because the spray component 5 is not fixedly connected to the second pipeline 2 during transportation, the total weight of the split-type housing is kept within transportation limits. Furthermore, the spray component 5 is installed inside the housing, eliminating the need for climbing during installation; operators can stand inside the housing to complete the assembly, thus eliminating the risk of falls from height.

[0046] Furthermore, when the weight of the split-type box meets the transportation requirements, the spray component 5 can be installed inside the box before transportation, thereby reducing the installation steps after arriving at the transportation location and improving installation efficiency.

[0047] Compared to existing technologies, the existing split-type enclosures use a prefabricated water and fire-fighting piping system, with the sprinkler components and piping fixedly connected before transportation, causing the transport weight of the enclosure to exceed the limit. This invention, however, designs the sprinkler component 5 and the second piping 2 as detachable structures, allowing them to be stored independently during transportation and quickly assembled on-site. Furthermore, in existing technologies, installing the sprinkler component on the top of the enclosure requires damaging the protective structure and performing high-altitude work. This invention, by adjusting the installation position of the sprinkler component 5 to inside the enclosure, maintains the enclosure's protection level while transforming high-altitude work into low-risk operations on the ground or inside the enclosure.

[0048] Through the above technical solution, this utility model realizes the modular transportation of the fire-fighting piping system of the split-type cabin. By detachably designing the sprinkler component 5 and the second pipe 2, the weight of the piping system during transportation is reduced to the core structure comprising only the first pipe 1, the second pipe 2, and the connector 7. The independent installation of the sprinkler component 5 after transportation avoids the technical contradiction of traditional prefabricated piping requiring full-set transportation, while also eliminating the reduced protection level and high-altitude operation risks caused by existing external installation methods.

[0049] In some embodiments of this utility model, such as Figure 1 , Figure 2 As shown, it also includes a third pipe 6, which is fixed on the top wall of the box. One end of the third pipe 6 is connected to the port of the second pipe 2 away from the first pipe 1. The third pipe 6 is provided with a second water outlet. The spray element 5 is installed on the second water outlet and sprays water into the box.

[0050] The third pipeline 6 refers to the fire branch pipe arranged on the top of the box, which is made of metal or flame-retardant plastic pipe and is fixed to the inside of the top wall by buckles or bolts, and is used to integrate the sprinkler system into the internal space of the box.

[0051] The second outlet refers to the opening structure that is spaced apart along the length of the third pipeline 6. Specifically, it is implemented by threaded interface or flange interface. Each interface corresponds to the installation of one spray element 5, so that the spacing of the spray points can be adjusted according to the internal equipment layout of the box.

[0052] The spray element 5 refers to a nozzle that sprays water mist downwards, specifically a wide-angle atomizing nozzle. Its water inlet is sealed to the second water outlet, and the spray direction is perpendicular to the bottom surface of the box.

[0053] Specifically, the third pipeline 6 extends the end of the second pipeline 2 to the top wall of the housing, forming a three-dimensional pipeline layout that combines longitudinal and transverse elements. The second pipeline 2 and the third pipeline 6 are connected by flanges or quick-release couplings, allowing the top pipeline module to be transported separately from the bottom pipeline. The spray element 5 is directly embedded in the second water outlet on the inner side of the top wall of the housing. The water mist coverage area covers the equipment below through the vertical spray angle from the top, without needing to penetrate the outer shell of the housing. During installation, operators only need to complete the pipeline connection inside the housing, avoiding the need to climb to the external roof for work.

[0054] Compared to existing technologies, when the existing split water pipes are externally placed on the top of the cabin, the pipes penetrate the cabin wall, resulting in a decrease in the protection level, and the exposed structure increases the transportation height. This invention integrates the third pipe 6 into the top wall, eliminating the need for wall-penetrating sealing of external pipes, while maintaining the cabin's IP55 protection level. The top-mounted installation of the spray unit 5 eliminates the need for workers to operate at heights externally; all connection work is completed inside the cabin, reducing the risk of falls.

[0055] Through the above technical solution, this utility model solves the problem of the box's sealing performance being compromised due to the external placement of split water pipes, transforming high-altitude installation work into internal ground operations and reducing construction safety hazards. The top-mounted layout of the spray unit 5 allows the extinguishing medium to evenly cover the equipment inside the box, improving fire response efficiency.

[0056] In some embodiments of this utility model, the connecting pipe 4 is a flexible structural component.

[0057] Flexible structural components refer to tubular connecting parts made of bendable materials, such as rubber hoses, corrugated pipes, or silicone tubes. These materials possess elastic deformation capabilities and can withstand a certain amount of displacement in both the axial and radial directions. In the piping system, flexible structural components absorb the relative displacement generated by the compartment's separate structures during transportation through their own deformation characteristics, thereby avoiding stress concentration in the piping caused by rigid connections.

[0058] Specifically, when the split-type cabin undergoes structural deformation during transportation, the flexible structural component connecting the first pipeline 1 and the second pipeline 2 adjusts the pipeline spacing through elastic expansion and contraction, while simultaneously utilizing the pleated structure of the pipe wall to buffer lateral vibration energy. This flexible connection method allows the pipeline system to adapt to the cabin separation state without disassembly during transportation. Pipeline joints are sealed using clamps, and construction personnel only need to adjust the bending angle of the flexible pipe sections after the cabins are joined to complete system assembly, eliminating the need for welding or thread calibration.

[0059] Compared to existing technologies, traditional split-type water pipelines use rigid PVC or metal pipes for rigid connections, which are prone to joint cracking under transportation vibrations. Furthermore, the need for complete disassembly of the pipeline during compartment separation leads to time-consuming on-site reassembly. This invention achieves a non-rigid continuous configuration of the pipeline system through a flexible connection structure, maintaining the system's integrity during transportation while eliminating the safety hazards of disassembly operations at height.

[0060] Through the above technical solution, this utility model effectively prevents mechanical damage to the pipeline connection structure during the transportation of the split-type cabin, reduces the installation positioning accuracy requirements caused by rigid constraints, reduces the amount of on-site high-altitude reassembly work, and enables the water fire protection system to adapt to the transportation form of the split-type cabin without affecting the protection level.

[0061] In some embodiments of this utility model, a first limiting part (not shown in the figure) is provided on the bottom of the bracket. The first limiting part extends along the first direction and is located at one edge of the bottom of the bracket. An installation channel (not shown in the figure) is provided in the first limiting part along the first direction. The first pipeline 1 is laid in the installation channel.

[0062] The first limiting part refers to a protruding structure extending along the bottom edge of the bracket. Specifically, it can be a metal profile connected to the bracket by welding or bolting, forming a continuous channel inside. This structure utilizes the supporting strength of the bottom edge of the bracket to provide linear guidance and constraint for the first pipeline 1, while simultaneously providing support for the split-type housing in the second direction (e.g., Figure 1 Limit the movement in the X direction (as shown).

[0063] The mounting channel refers to a passage that penetrates the interior of the first limiting part. Specifically, it can have a circular or rectangular cross-section, with its inner diameter forming a clearance fit with the outer diameter of the first pipe 1. This channel completely encloses the first pipe 1 within the support structure through an embedded installation method, preventing the pipe from directly contacting the external environment.

[0064] Specifically, after the first pipe 1 is embedded in the mounting hole, its axial extension direction is consistent with the bottom length direction of the container support. The first limiting part is located at the bottom edge of the support, using the mechanical strength of the support body structure to limit the lateral displacement of the first pipe 1. The continuous extension feature of the mounting hole ensures that the vibration load borne by the first pipe 1 during transportation is evenly transmitted to the support, avoiding local stress concentration. By hiding the first pipe 1 inside the support, the risk of damage to the cabin sealing performance caused by traditional external pipes is eliminated, and there is no need to disassemble the pipe before transportation.

[0065] Compared to existing technologies, conventional split-type water pipes are typically installed on the top of the container exterior, exposing the pipes to the external environment. This necessitates the addition of waterproof sealing structures and poses a risk of collision during transport. This invention integrates the first pipe 1 into the mounting hole at the bottom of the support frame, physically fusing the pipe system with the container's main structure. This maintains the integrity of the protection level while reducing the risk of pipe deformation or detachment during transport.

[0066] Through the above technical solutions, this utility model achieves a rigid connection between the pipeline system and the support structure, eliminating pipeline displacement caused by transportation vibration; avoids sealing failure caused by exposed pipelines through the concealed layout, maintaining the protection level of the cabin; and reduces on-site assembly procedures and disassembly requirements before transportation of the split cabin through the installation channels prefabricated inside the support.

[0067] In some embodiments of this utility model, the mounting channel is provided with a through hole (not shown in the figure) corresponding to the first water outlet, and the connecting pipe 4 passes through the through hole to connect the first pipe 1 and the second pipe 2.

[0068] The mounting channel refers to the channel formed inside the limiting structure extending along the bottom edge of the bracket. Specifically, it can be implemented using a hollow structure inside a metal profile with a circular or rectangular cross-section, used to constrain the laying path of the first pipeline 1. The through hole refers to a perforation opened on the wall of the mounting channel, specifically formed by laser cutting or drilling. Its position coincides with the central axis of the first outlet, ensuring that the connecting pipeline 4 can be aligned with the outlet of the first pipeline 1 to complete the sealing connection.

[0069] Specifically, the mounting channel is formed at the bottom edge of the bracket via the first limiting part, and the first pipe 1 is fixed inside the mounting channel. When the second pipe 2 needs to be connected, the connecting pipe 4 passes through the through hole on the outer wall of the mounting channel, forming a sealed connection with the first outlet of the first pipe 1 through the through hole. The positional accuracy of the through hole is ensured by positioning fixtures, for example, the through hole is machined simultaneously during the mounting channel forming stage to ensure that each through hole is coaxial with its corresponding first outlet. When the connecting pipe 4 passes through the through hole, a rubber sealing ring can be provided between its outer wall and the inner wall of the through hole to prevent water leakage.

[0070] Compared to existing technologies, traditional split-type fire-fighting pipelines are installed on the top of the cabin, requiring connection ports at the top, which reduces the protection level and necessitates high-altitude work during installation. This invention integrates the connection structure within the mounting holes at the bottom of the bracket, achieving concealed connection through pre-positioned through-holes without altering the top structure of the cabin. The connecting pipeline 4 is disassembled and assembled through the bottom through-holes, reducing the operating height to a safe ground-level working range.

[0071] Through the above technical solution, this utility model achieves rapid assembly and disassembly of the pipeline system, meeting the pipeline separation requirements during the transportation of split-type cabins and avoiding overweight transport. The bottom-concealed design of the connection structure maintains the integrity of the cabin top, preventing external environmental intrusion from affecting the protection level. Installation is completed at ground level, eliminating the risk of falls from heights, and the connection operation achieves rapid docking through the through-hole positioning, reducing on-site operation time.

[0072] In some embodiments of this utility model, a connector 7 is also included, which connects the first pipeline 1 and the water supply pipe 3.

[0073] The connector 7 is an independent structural component used to establish a fluid channel between the first pipeline 1 and the water supply pipe 3. Specifically, it can be implemented using a tee joint, with its three interfaces connecting the first pipeline 1, the water supply pipe 3, and the second pipeline 2 respectively, forming a detachable modular connection node. This connector 7 acts as an independent break point, allowing the water supply pipe 3 to be separated from the fire-fighting main circuit during transportation, thereby reducing the overall weight of the cabin; during deployment, it simplifies the on-site installation process by quickly restoring the connection. The multi-directional interface design of the tee joint enables functional integration of the piping system, avoiding a decrease in protection level caused by external piping.

[0074] Specifically, the water supply pipe 3 is detachably connected to the first pipeline 1 via the connector 7. When transporting the split-type cabin, the pipeline interface at the connector 7 is disconnected, and the water supply pipe 3 and the first pipeline 1 are transported independently, effectively reducing transportation weight. Upon arrival at the site, the water supply pipe 3 only needs to be reconnected to the first pipeline 1 via the connector 7 to restore the water supply function. The modular design of the connector 7 allows the connection between the water supply pipe 3 and the fire main circuit to be independent of the cabin's external structure, thereby eliminating the risk of working at height required for installing pipes on the top of the cabin in traditional solutions, and avoiding damage to the cabin's protective performance due to external pipes.

[0075] Compared to existing technologies, traditional split-type water pipelines typically use prefabrication or welding to connect the water supply pipe 3 to the main circuit, resulting in the pipeline being unable to be disassembled and the cabin weight exceeding the limit during transportation. However, the detachable connection achieved through the connector 7 allows the water supply pipe 3 and the main circuit to be transported separately, reducing transportation costs. Furthermore, existing technologies require additional reinforcement to maintain the protection level when the pipeline is located on the top of the cabin exterior, while this invention integrates the water supply pipe 3 and the main circuit inside the cabin through the connector 7, without altering the external structure of the cabin, thus avoiding the risk of a decrease in the protection level.

[0076] Through the above technical solution, this utility model solves the problem of reliable connection between the water supply pipe 3 and the first pipe 1 in the fire protection pipeline system of the split cabin. The pipeline can be transported separately by means of the detachable connector 7, which reduces the transportation weight and the complexity of on-site installation, while avoiding the reduction of cabin protection level and the risk of working at height due to the external placement of the pipeline.

[0077] In some embodiments of this utility model, the connector 7 is configured as a three-way structure, and the connector 7 connects the first pipeline 1, the second pipeline 2 and the water supply pipe 3.

[0078] The tee fitting refers to a tubular connection component with three converging fluid channels. Specifically, it can be implemented using a stainless steel cast or injection-molded Y-shaped or T-shaped tee connector. Its three interfaces are respectively matched and connected to the ports of the first pipeline 1, the second pipeline 2, and the water supply pipe 3. This structure replaces the splicing of multiple pipe sections with a single connection node, reducing the number of connection points in the pipeline system.

[0079] The water supply pipe 3 refers to the pipeline used to introduce external water sources. Specifically, it can be a pressure-resistant metal pipe or a reinforced plastic pipe. Its port forms a branch channel with the first pipeline 1 and the second pipeline 2 through a three-way structural component, so as to realize the bidirectional distribution of external water sources to the interior of the energy storage container.

[0080] Specifically, the three-way connector is installed at the junction of the side wall of the energy storage container and the bottom of the support frame. The port of the first pipe 1 extending along the bottom of the support frame, the port of the second pipe 2 fixed to the inner wall of the container, and the port of the water supply pipe 3 are respectively sealed and connected to the three interfaces of the three-way connector. When external water is input through the water supply pipe 3, the water flows through the three-way connector and simultaneously enters the first pipe 1 and the second pipe 2: the first pipe 1 delivers water to the bottom area of ​​the support frame, and the second pipe 2 guides the water to the internal space of the container. This integrated connection method eliminates the redundant structure of connecting the water supply pipe 3 to the two branch pipes separately in the traditional solution, allowing the pipeline system to be pre-installed before transportation, avoiding the operation of disassembling the pipeline during the transportation of the separate compartment.

[0081] In some specific embodiments, the three interfaces of the tee fitting are configured with different pipe diameters. For example, the first pipe 1 interface uses a standard DN25 size, the second pipe 2 interface uses a DN20 size, and the water supply pipe 3 interface uses a DN32 size, to accommodate the flow distribution requirements of different pipes. The inner wall of the tee fitting may be provided with flow-guiding ribs to optimize the proportion of water flow distributed to the first pipe 1 and the second pipe 2.

[0082] Compared to existing technologies, conventional split-type water pipelines require the installation of an independent connection structure between the water supply pipe 3 and the branch pipes on the top of the enclosure, resulting in openings on the top of the enclosure that affect the protection level, and the installation process requires high-altitude work. This invention, however, uses a three-way connector to centrally connect the water supply pipe 3 and the two branch pipes on the side wall of the enclosure, eliminating the need for additional pipe interfaces on the top. This maintains the enclosure's sealing integrity and allows all connection work to be completed at a height accessible to personnel. Furthermore, in traditional solutions, the water supply pipe 3 and the two branch pipes need to be connected through two independent connectors, while this invention reduces the number of connection points, significantly lowering the risk of leakage.

[0083] Through the above technical solutions, this utility model enables the fire protection piping system to be pre-assembled before transporting the modular cabin, avoiding the problem of overweight due to disassembly; the integrated connection of the three-way structural components reduces high-altitude operations and eliminates the risk of personnel falling; at the same time, the centralized connection method of the side walls of the cabin avoids openings at the top, maintaining the cabin's protection level. The overall prefabrication of the piping system also reduces on-site installation time; for example, the operation that requires 6 connection steps in the traditional solution is reduced to 3 steps.

[0084] According to an embodiment of the present invention, the energy storage container includes the fire-fighting piping system described above.

[0085] The fire-fighting piping system refers to a detachable piping structure consisting of the first pipe 1, the second pipe 2, and the water supply pipe 3. The first pipe 1 can extend along the bottom of the energy storage container support, for example, by laying metal or plastic pipes, to support and connect the water supply pipe 3. The second pipe 2 can be detachably connected to the first pipe 1, for example, via flanges or quick couplings, to allow for partial separation of the piping during transport to reduce weight. The water supply pipe 3 can be installed on the side wall of the container, for example, by welding or bolting, to connect to an external water source and supply water to the first pipe 1.

[0086] Specifically, the first pipeline 1 extends and is fixed along the bottom of the energy storage container support. One end of the water supply pipe 3 is connected to the first pipeline 1, and the other end leads to the external environment. The second pipeline 2 is detachably connected to the first pipeline 1 and fixed to the inner wall of the container, with its opening facing the interior of the container. The connection of the water supply pipe 3 to an external water source ensures the integrity of the fire protection system. The piping system is built into the container, avoiding the impact of external installation on the protection level and eliminating the need for working at height.

[0087] Compared to existing technologies, current split-type water pipelines are typically installed on the top of the outer casing, resulting in reduced protection levels and the need for high-altitude operations. This invention integrates the pipeline system inside the casing, achieving weight reduction during transport through a detachable design. Existing technologies require extensive on-site installation work, while this invention reduces on-site workload through pre-installed pipelines. Furthermore, existing external pipelines pose a risk of collision during transport, while the built-in pipelines of this invention prevent damage to the external structure during transportation.

[0088] Through the above technical solution, this utility model solves the problem of excessive weight during transportation caused by the prefabrication and installation of the water fire-fighting system in a split-type cabin. Weight reduction during transportation is achieved through a detachable piping structure. The built-in piping design avoids the negative impact of external installation on the protection level and eliminates the safety risks of working at heights. The pre-installed piping system reduces on-site installation work and lowers construction costs. The detachable connection method ensures the integrity of the fire-fighting function while meeting transportation weight limits.

[0089] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
