Description

Technical Field

[0001] This utility model relates to the field of energy storage container technology, and in particular to a pipeline connection structure and a container energy storage system. Background Technology

[0002] Centralized energy storage systems using standard shipping containers have become one of the mainstream solutions. This system highly integrates a large number of battery clusters, battery management systems, power conversion systems (PCS), cooling equipment, and supporting electrical and thermal management piping within a single enclosed space the size of a standard shipping container, forming a complete energy storage unit that can be deployed, transported, and commissioned in batches. While this integrated design saves site space and improves system integrity, it also presents significant challenges to equipment layout and pipeline planning within the limited space inside the container.

[0003] Because energy storage containers need to accommodate numerous battery clusters and their corresponding cooling and fire-fighting pipes, the pipeline network is often intricate and densely arranged. To achieve the branching, convergence, and directional conversion of multiple pipelines within a limited space, existing technologies generally use traditional standard pipe fittings such as tees and 90° elbows for mechanical connections. These connections usually require threaded or flanged fastening, and the ease of installation and maintenance directly affects the efficiency of system integration, the difficulty of subsequent operation and maintenance, and the utilization rate of internal space.

[0004] However, traditional tees and 90° elbows have significant drawbacks in actual installation. When finally tightening these fittings, the entire assembly often needs to be rotated and tightened along the pipe's centerline. This operation requires ample wrench space around the joint. In situations where equipment layout within energy storage containers is extremely compact, and pipes often need to be close to the container's sheet metal or pass through narrow gaps, the joint location can easily become severely restricted in terms of operating space due to its proximity to the sheet metal walls or other equipment. Once the joint is blocked by sheet metal, conventional screw-on installation methods cannot be implemented. To solve this problem, on-site pipe welding is often the only option. However, this not only increases the difficulty of production and assembly processes, but also consumes more time and labor. Furthermore, sparks and slag generated during welding may fall onto nearby batteries, cables, or precision electronic equipment, causing potential damage or safety hazards, thus affecting the reliability and lifespan of the entire energy storage system.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0018] Figure 1 This is a schematic diagram of the pipe connection structure provided in an embodiment of the present utility model; Figure 2 This is a schematic diagram of the structure of the pipe connector body provided in this embodiment of the utility model; Figure 3 This is a schematic diagram of the snap fastener structure provided in an embodiment of the present utility model; Figure 4 This is a schematic diagram of the docking structure provided in an embodiment of the present utility model; Figure 5 This is a schematic diagram of the mating structure between a docking structure and an open pipe section in this utility model; Figure 6 This is a schematic diagram of another mating structure and the fitting structure of an open pipe section in this utility model. For example... Figures 1 to 6 As shown, this utility model embodiment provides a pipe connection structure, including: a pipe joint body 1 and a butt joint structure 2.

[0019] The pipe connector body 1 is provided with multiple interconnected open pipe sections 11, and each open pipe section 11 has a mating opening 111 at its end. Each open pipe section 11 is provided with a locking structure 12, which includes a mounting base 121 provided on the outer wall of the open pipe section 11 and a snap fastener 122 hinged to the mounting base 121. The snap fastener 122 has a locking tooth 123 on the side near the mating interface.

[0020] Multiple docking structures 2 are provided for corresponding open pipe sections 11. The docking structure 2 includes a connector pipe 21 and a mating flange 22 that protrudes radially from one end of the connector pipe 21. One end of the connector pipe 21 is engaged with the docking opening 111 of the corresponding open pipe section 11, and is engaged with the locking teeth 123 by the mating flange 22. The other end of the connector pipe 21 has an internal thread on its inner wall.

[0021] In this embodiment of the invention, the pipe connector body 1 can be a tee connector structure with three interconnected open pipe sections 11. The internal flow channels of these three open pipe sections 11 are interconnected, thereby realizing the function of fluid convergence or diversion between multiple pipelines. Each open pipe section 11 has a docking opening 111 at its end, which is used to connect with the docking structure 2, thereby connecting the pipe connector body 1 with the external container pipeline.

[0022] To achieve a reliable connection and quick assembly / disassembly between the docking structure 2 and the pipe fitting body 1, a locking structure 12 is provided on each open pipe section 11. This locking structure 12 includes a mounting base 121 disposed on the outer wall of the open pipe section 11 and a snap fastener 122 hinged to the mounting base 121. The mounting base 121 is fixedly mounted on the outer wall of the open pipe section 11, providing hinged support for the snap fastener 122. The snap fastener 122 is hinged to the mounting base 121, allowing it to rotate relative to the open pipe section 11, thus achieving both locking and unlocking states. A locking tooth 123 is provided on the side of the snap fastener 122 near the docking opening 111, which engages with the mating flange 22 of the docking structure 2.

[0023] For each open pipe segment 11, this embodiment provides a mating structure 2. Since the pipe fitting body 1 has multiple open pipe segments 11, multiple mating structures 2 are also provided accordingly, each mating structure 2 connecting to one open pipe segment 11. The mating structure 2 includes a fitting pipe 21 and a mating flange 22 protruding radially from one end of the fitting pipe 21. The fitting pipe 21 has a tubular structure; one end is used to connect to the open pipe segment 11 of the pipe fitting body 1, and the other end is used for threaded connection to the container pipe. The mating flange 22 protrudes radially outward from the fitting pipe 21, forming an annular protrusion structure. The outer diameter of the mating flange 22 is larger than the outer diameter of the fitting pipe 21, thereby enabling an effective engaging relationship with the locking teeth 123 of the locking structure 12.

[0024] During assembly, one end of the connector tube 21 is engaged with the mating opening 111 of the corresponding open pipe section 11. Specifically, the operator aligns the connector tube 21 with the mating opening 111 of the open pipe section 11 and inserts the connector tube 21 into the mating opening 111, so that the end of the connector tube 21 and the open pipe section 11 form a mating fit. At this time, the mating flange 22 on the connector tube 21 is located near the locking teeth 123 of the locking structure 12. Subsequently, by flipping the snap 122, the locking teeth 123 and the mating flange 22 engage with each other, thereby firmly locking the connector tube 21 onto the open pipe section 11. In the engaged state, the mating flange 22 is held by the locking teeth 123, forming a reliable mechanical connection and preventing the connector tube 21 from falling off due to fluid pressure or external vibration during use.

[0025] The other end of the connector pipe 21 has an internal thread on its inner wall, which is used for threaded connection with the external thread of the container pipe 32. By rotating the container pipe 32, its external thread engages with the internal thread of the connector pipe 21, a reliable connection between the pipe and the connector body 1 can be achieved. The key advantage of this connection method is that only the container pipe 32 or the connector pipe 21 needs to be rotated during the connection process, without rotating the entire connector body 1. Therefore, even if the connector body 1 is close to the sheet metal wall 31 or located in a space-constrained area, the pipe installation and connection operation can be completed smoothly.

[0026] When connecting the container pipe 32 to the pipe fitting body 1, first insert one end of the fitting pipe 21 into the mating opening 111 of the corresponding open pipe section 11. Then, by operating the snap 122, the locking teeth 123 engage with the mating flange 22, thereby fixing the fitting pipe 21 onto the pipe fitting body 1. At this time, the other end of the fitting pipe 21 is exposed, and the operator can easily screw the container pipe 32 into the internal thread of the fitting pipe 21 to complete the pipe connection. Alternatively, the operator can first complete the thread assembly of each fitting pipe 21 with the container pipe 32, and then mate the fitting pipe 21 with each open pipe section 11. Throughout the connection process, the pipe fitting body 1 does not need to be rotated; only the snap 122 needs to be pressed and the container pipe 32 rotated, significantly reducing the requirements for surrounding operating space. When it is necessary to disassemble the pipe, the operator first unscrews the container pipe 32 from the fitting pipe 21, and then presses the snap 122 to unlock it, allowing the fitting pipe 21 to be removed from the open pipe section 11. The maintenance operation is simple and quick.

[0027] This embodiment achieves rapid assembly and disassembly of pipe connections by setting up a pipe connector body 1 and cooperating with a locking structure 12 and a docking structure 2. This solves the problem of traditional tee connectors requiring rotation of the entire assembly and demanding operating space. In the case of densely packed pipes within an energy storage container, close to sheet metal walls, the pipe connection structure of this embodiment can complete pipe connections within a confined space, avoiding welding operations and eliminating the safety hazard of welding residue potentially damaging surrounding batteries, cables, and other equipment. This improves assembly efficiency and system reliability.

[0028] Optionally, the mounting base 121 includes two parallel and spaced-apart support plates 1211, and a rotating shaft 1212 passing between the two support plates 1211. The snap fastener 122 is rectangular and passes through the rotating shaft 1212 in the middle to be hinged between the two support plates 1211. A torsion spring 1213 is sleeved on the rotating shaft 1212, with one end of the torsion spring 1213 connected to the snap fastener 122 and the other end connected to the open pipe section 11. Exemplarily, in this embodiment of the present invention, the two support plates 1211 are vertically fixed to the outer wall of the open pipe section 11, maintaining a certain distance between them to accommodate the snap fastener 122's hinged rotation. The two ends of the rotating shaft 1212 pass through the two support plates 1211 respectively and are fixed to the support plates 1211, forming a fixed rotating shaft.

[0029] The snap fastener 122 has a rectangular plate-like structure, with its central portion passing through a pivot rod 1212, thus hinged between two support plates 1211. Specifically, the snap fastener 122 has a through hole in its central position, through which the pivot rod 1212 passes, allowing the snap fastener 122 to rotate and flip around the pivot rod 1212 as its axis. One end of the snap fastener 122 has a locking tooth 123, and the other end serves as an operating end for the operator to press and operate.

[0030] To ensure that the snap 122 maintains a stable engaging force in the locked state, a torsion spring 1213 is fitted onto the rotating shaft 1212. The torsion spring 1213 is fitted onto the rotating shaft 1212, with one end connected to the snap 122 and the other end connected to the open tube section 11. In its free state, the torsion spring 1213 has a preload torque, causing the snap 122 to tend to flip towards the side where the locking teeth 123 are located, thereby applying a continuous clamping force to the mating flange 22.

[0031] In the operation of this embodiment, after the connector tube 21 is inserted into the mating opening 111, the operator releases the snap 122. The elastic restoring force of the torsion spring 1213 causes the snap 122 to automatically flip to the locking position, pressing the locking teeth 123 against the mating flange 22 to form a stable locking connection. The torsion spring 1213 provides elastic support between the snap 122 and the opening tube section 11, keeping the locking angle between the snap 122 and the mating flange 22 at an acute angle, thereby generating a large locking force. This acute-angle locking design means that when the mating flange 22 attempts to disengage under fluid pressure or external vibration, it will encounter greater resistance from the locking teeth 123, effectively preventing the connector tube 21 from accidentally falling off.

[0032] When it is necessary to disassemble the connector tube 21, the operator presses the operating end of the snap 122, causing the snap 122 to overcome the elastic force of the torsion spring 1213 and flip to the unlocked position. At this time, the retaining tooth 123 separates from the mating flange 22, and the connector tube 21 can be taken out from the mating opening 111. The entire disassembly and assembly process does not require any tools and can be completed by manual pressing, which is simple to operate and easy to maintain.

[0033] In this embodiment, the elastic force provided by the torsion spring 1213 enables the locking structure 12 to have a self-locking function, which not only improves the reliability and tightness of the connection, but also simplifies the assembly operation steps and further enhances the ease of assembly in a confined space.

[0034] Optionally, the locking tooth 123 is provided with an arcuate concave surface 1231 that matches the outer wall of the connector tube 21. Exemplarily, in this embodiment of the invention, the radius of curvature of the arcuate concave surface 1231 is adapted to the outer diameter of the connector tube 21, so that when the locking tooth 123 engages with the mating flange 22, the arcuate concave surface 1231 can fit against the outer wall surface of the connector tube 21, increasing the contact area between the locking tooth 123 and the connector tube 21, making the locking force distribution more uniform, avoiding stress concentration that may be caused by point contact or line contact, and improving clamping stability.

[0035] Optionally, each open pipe section 11 is provided with two locking structures 12, which are symmetrically arranged with respect to the axis of the open pipe section 11. Exemplarily, in this embodiment of the invention, the two locking structures 12 are respectively installed on opposite sides of the outer wall of the open pipe section 11, symmetrically distributed at 180° with the central axis of the open pipe section 11 as the axis of symmetry. Each locking structure 12 includes a mounting base 121 and a snap fastener 122. The locking teeth 123 of the two snap fasteners 122 apply a locking force to the mating flange 22 from opposite sides. The two locking structures 12 simultaneously apply locking forces to the mating flange 22 from opposite directions, balancing the locking forces radially. This avoids the possibility of misalignment or uneven force on the connector pipe 21 caused by unilateral locking, ensuring that the axis of the connector pipe 21 remains coaxial with the axis of the open pipe section 11, thus improving the coaxiality and sealing of the connection.

[0036] Optionally, one end of the connector tube 21 is sleeved on the outer wall of the open pipe section 11, and the end face of one end of the connector tube 21 abuts against the mounting base 121. Exemplarily, in one possible implementation of this utility model, refer to... Figure 5The connector pipe 21 is designed as a sleeve structure, with the inner diameter of one end slightly larger than the outer diameter of the open pipe section 11, allowing it to be fitted onto the outer wall of the open pipe section 11. During assembly, the connector pipe 21 is inserted from the end of the open pipe section 11 until its end face abuts against the side of the mounting base 121. The mounting base 121 acts as a limit, preventing the connector pipe 21 from being inserted too deeply and ensuring that the connector pipe 21 and the mating opening 111 are in the correct mating position. The connector pipe 21 is fitted onto the outside of the open pipe section 11, forming an external connection. The connection interface is on the outer surface of the pipe, resulting in a larger sealing area, which helps improve sealing reliability. Secondly, the sleeve structure creates a longer mating length between the connector pipe 21 and the open pipe section 11, increasing the overlap area of ​​the connection, improving connection strength and bending stiffness, and enabling the connection to withstand greater external loads and bending moments. Furthermore, the end face of the connector tube 21 abuts against the mounting base 121 to form axial positioning, making the installation position of the connector tube 21 precise and controllable, and avoiding the impact on the engagement relationship between the mating flange 22 and the locking teeth 123 due to improper insertion depth.

[0037] Optionally, one end face of the connector tube 21 is provided with a snap-fit ​​groove 211 that matches the mating opening 111, and the snap-fit ​​groove 211 engages with the corresponding mating opening 111. Exemplarily, in another possible implementation of this utility model, refer to... Figure 6 A snap-fit ​​groove 211 is machined on the end face of the connector pipe 21. The shape and size of the snap-fit ​​groove 211 match the inner and outer diameters of the mating opening 111. During assembly, when the connector pipe 21 is fitted onto the open pipe section 11, the snap-fit ​​groove 211 and the boss of the mating opening 111 interlock. The snap-fit ​​between the snap-fit ​​groove 211 and the mating opening 111 forms an axial stop, preventing the connector pipe 21 from moving axially relative to the open pipe section 11, thus improving the axial positioning accuracy and stability of the connection. Secondly, the stepped fit between the snap-fit ​​groove 211 and the mating opening 111 increases the effective contact area of ​​the connection interface, allowing fluid pressure to act on a larger area, reducing the specific pressure of the sealing surface, reducing the wear of the sealing ring, and extending the service life of the sealing ring 113. Thirdly, the stepped surface formed by the snap-fit ​​structure can effectively prevent the connector pipe 21 from rotating when subjected to external impact or vibration, improving the torsional resistance of the connection.

[0038] Optionally, an annular groove 112 is provided on the outer wall of the open pipe section 11 near the docking opening 111, and a sealing ring 113 is provided within the annular groove 112. Exemplarily, in this embodiment of the invention, the annular groove 112 is machined on the outer wall surface of the open pipe section 11 near the docking opening 111, forming an annular groove structure, the width and depth of which are determined according to the size specifications of the sealing ring 113. The sealing ring 113 is made of rubber, silicone, or other elastic sealing materials, and its cross-sectional shape can be circular, square, or other shapes suitable for sealing. The sealing ring 113 is installed within the annular groove 112, partially embedded in the groove and partially protruding from the outer surface of the open pipe section 11. The sealing ring 113 effectively prevents fluid leakage from the mating gap between the connector pipe 21 and the open pipe section 11, ensuring the airtightness or liquid tightness of the pipeline system and improving the safety and reliability of the energy storage system. Furthermore, the annular groove 112 positions and protects the sealing ring 113, preventing displacement or detachment during assembly or use, ensuring the long-term effectiveness of the seal. Furthermore, the elastic deformation of the sealing ring 113 can compensate for the small gaps between the joint pipe 21 and the open pipe section 11 caused by processing or installation errors, thereby improving the sealing reliability of the connection and the tolerance to manufacturing precision.

[0039] Figure 7 This is a schematic diagram of the internal structure of a containerized energy storage system provided in an embodiment of this utility model. Figure 7 As shown in the figure, this utility model embodiment also provides a containerized energy storage system, including as follows: Figures 1 to 6 The illustrated pipe connection structure also includes a container body 3. The container body 3 contains sheet metal walls 31 and multiple container pipes 32. Pipe connection components are located beside the sheet metal walls 31. The multiple container pipes 32 are threadedly connected to connector pipes 21 at multiple open pipe sections 11. In this embodiment, the sheet metal walls 31 serve as partitions within the container body 3, dividing the internal space into different functional areas, such as a battery compartment and an electrical equipment compartment. The multiple container pipes 32 include cooling pipes, fire-fighting pipes, etc., which are distributed longitudinally and laterally within the container body 3 to achieve functions such as thermal management and fire protection.

[0040] The pipe connection structure is located beside the sheet metal wall 31. Specifically, the pipe joint body 1 is arranged adjacent to the sheet metal wall 31, and its various open pipe sections 11 extend in different directions. The multi-port container pipes 32 are threadedly connected to the joint pipes 21 at the multiple open pipe sections 11. Each container pipe 32 has an external thread at its end, which mates with the internal thread on the inner wall of the joint pipe 21. The threaded connection between the container pipe 32 and the joint pipe 21 can be achieved by rotating the container pipe 32.

[0041] In the application scenario of this embodiment, the pipe connector body 1 is arranged tightly against the sheet metal wall 31, resulting in extremely limited operating space. If a traditional tee connector is used, the entire tee connector needs to be rotated to complete the pipe connection. However, due to the obstruction of the sheet metal wall 31, the wrench cannot apply rotational torque, making assembly impossible. With the pipe connection structure of this invention, the operator only needs to snap the connector pipe 21 onto the open pipe section 11 of the pipe connector body 1, lock it by pressing the snap 122, and then rotate the container pipe 32 to connect it to the connector pipe 21 via thread. The entire connection process does not require rotating the pipe connector body 1 and is completely unrestricted by the space of the sheet metal wall 31, greatly improving assembly efficiency.

[0042] Furthermore, by eliminating welding operations and the resulting sparks and slag, sensitive components such as batteries and electrical equipment within the container 3 are effectively protected from damage by welding slag, thus improving the safety and reliability of the energy storage system. Simultaneously, the threaded connection method simplifies and expedites the disassembly and replacement of pipelines, significantly reducing system maintenance costs and downtime, and enhancing the economic efficiency and maintainability of the energy storage system.
