[0032] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0033] In the description of the present application, it should be understood that the orientation or positional relationships indicated by terms such as "height", "thickness", "upper", "lower", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application. In the description of the present application, the meaning of "multiple" is two or more, and at least one means it can be one, two or more, unless otherwise clearly and specifically defined.

[0034] It should also be noted that in the drawings of the embodiments of the present application, the arrow marked with X represents the first direction X of the plate body, and the arrow marked with Y represents the second direction Y of the plate body. The introduction of the first direction X and the second direction Y is to more clearly describe the structures and relative positional relationships of the components in the pipeline sealing structure. In actual applications, the first direction X and the second direction Y may change according to the different placement methods of the pipeline sealing structure.

[0035] As a prelude to the embodiments of the present application, the current development trend of large-scale energy storage systems is to adopt liquid-cooled energy storage systems. When the liquid-cooled pipeline passes through the sealed compartment, the sealing measures usually adopt fireproof mud or heat-shrinkable sleeves. When using fireproof mud for plugging, to ensure the sealing performance, the fireproof mud needs to be evenly applied to the gap between the opening in the compartment and the pipeline. According to the usage instructions of the fireproof mud, confirm its curing time. During the curing period, avoid touching or disturbing the coating. After the fireproof mud is cured, conduct necessary inspections and tests to ensure that the quality and performance of the coating meet the requirements, and the construction period is long. When using heat-shrinkable sleeves, after uniformly heating the heat-shrinkable sleeves, it is also necessary to wait for the heat-shrinkable sleeves to cool naturally, which takes a long time. Therefore, the conventional fireproof mud or heat-shrinkable sleeve solutions all have the situation of low working efficiency.

[0036] Please refer to Figure 1 and Figure 2 The pipeline sealing structure of the embodiment of the present application is used to seal the gap between the outer peripheral wall of the liquid-cooled pipe 5 and the pipe hole 61 provided on the compartment 6. The pipeline sealing structure includes a sealing plate 1, a sealing member 2, and a plurality of fixing members 3. The sealing plate 1 is used for sealing connection with the compartment 6. The sealing plate 1 includes a sealing pipe 11, and the sealing pipe 11 communicates with the pipe hole 61; the sealing pipe 11 is a hollow cylindrical pipeline, the inner diameter of the sealing pipe 11 is larger than the inner diameter of the pipe hole 61, and the orthographic projection of the sealing pipe 11 on the compartment 6 along its own axis is located outside the pipe hole 61. The sealing member 2 is in the shape of a hollow cylinder, or is similar to a hollow cylinder. One end of the sealing member 2 is sleeved on the sealing pipe 11, and the other end is sleeved on the liquid-cooled pipe 5. At least one fixing member 3 is respectively arranged at both ends of the sealing member 2 along its own axis. The fixing member 3 is configured to squeeze the sealing member 2 so that the sealing member 2 is respectively in sealing connection with the sealing pipe 11 and the liquid-cooled pipe 5.

[0037] Under the pressure of the fixing member 3, the seal 2 is tightly wrapped around the outer surface of the sealing tube 11 and the liquid cooling tube 5, and the gap between them is blocked, thereby achieving a sealed connection. Since the sealing plate 1 is sealed and connected to the cabin 6, the medium in the space on one side of the cabin 6 flows through the tube hole 61 to the space path on the other side, which is blocked by the seal 2. During assembly, the seal 2 is placed on the sealing tube 11 and the liquid cooling tube 5, and then the seal 2 is fastened to the sealing tube 11 and the liquid cooling tube 5 through the fixing member 3. At the same time, the force acting on the seal 2 mainly depends on the mechanical locking force brought by the fixing member 3. The seal can be sealed by tightening, which saves the waiting time required for conventional sealing methods and improves the efficiency of the sealing work of the liquid cooling tube 5. Due to the limited space in the energy storage cabinet, the method of connecting with the fixing member 3 is simple in steps and can facilitate assembly operations. In addition, the seal 2 is arranged on one side of the cabin 6, and the entire sealing structure does not need to pass through the cabin 6, which further facilitates the assembly work and also plays a protective role for the cabin 6.

[0038] Please combine Figure 1 and Figure 2 In some embodiments, the sealing plate 1 further includes a plate body 12, which is sealedly connected to the cabin 6. For example, fasteners can be used to secure the plate body 12 to the side wall of the cabin 6. The plate body 12 is provided with a through hole 121, which communicates with the pipe hole 61 and is located outside the pipe hole 61. The sealing tube 11 is provided on the side of the plate body 12 away from the cabin 6 and is connected to the plate body 12. The inner diameter of the sealing tube 11 is not less than that of the through hole 121, and the sealing tube 11 communicates with the pipe hole 61 through the through hole 121. The plate body 12 is provided with a waist hole 122, which is provided along the thickness direction of the plate body 12. The plate body 12 increases the contact area between the sealing tube 11 and the cabin 6, so that the plate body 12 has sufficient volume to connect with the cabin 6 and seal. When installing the plate body 12, bolts can be passed through the waist hole 122 and screwed into the pre-drilled screw holes on the side wall of the cabin 6, and the plate body 12 and the cabin 6 can be fixed by the bolts; the length of the waist hole 122 is greater than the outer diameter of the threaded section of the bolt, so that the bolt can move freely within a certain range, thereby adjusting its relative position with the screw hole to accommodate slight deviations or deformations during the assembly process. In some other embodiments, embedded bolts can be arranged on the side wall of the cabin 6, and the embedded bolts are passed through the waist hole 122, and then the plate body 12 is fixed by nuts and embedded bolts. In some other embodiments, the plate body 12 and the cabin 6 can also be connected in the form of sealant. For example, the sealant can be selected from silicone sealant, polyurethane sealant, acrylic sealant, polysulfide sealant, etc., or a combination of bolt fixation and sealant filling of gaps can be adopted.

[0039] Please combine Figure 1 and Figure 3, in some embodiments, the pipeline sealing structure has a plurality of waist-shaped holes 122. The plurality of waist-shaped holes 122 are respectively arranged on both sides of the sealing pipe 11 in the first direction X and are arranged at intervals in the second direction Y. The first direction X is the width direction of the plate body 12, the second direction Y is the length direction of the plate body 12, and the first direction X and the second direction Y intersect. The plurality of waist-shaped holes 122 enable a plurality of fasteners to be correspondingly configured when connecting the plate body 12, increasing the fastening force applied to the plate body 12. At the same time, the arrangement positions of the plurality of waist-shaped holes 122 enable the fastening force to be relatively evenly distributed, so that the plate body 12 is closely attached to the side wall of the cabin 6, reducing the gap between them, so as to improve the sealing effect.

[0040] Please refer to Figure 3 and Figure 4 , in some embodiments, the waist-shaped holes 122 are arranged to extend along the first direction X or the second direction Y. By extending the length of the waist-shaped holes 122, the adjustment margin of the fasteners in the first direction X or the second direction Y is increased to adapt to the dimensional deviation or deformation during the assembly process, thereby improving the flexibility and fault tolerance of the assembly.

[0041] Please refer to Figure 1 , in some embodiments, the seal 2 is an elastic seal 2, and the fixing member 3 is configured to squeeze the seal 2 so that the seal 2 undergoes elastic deformation and respectively seals the gaps between the sealing pipe 11 and the liquid cooling pipe 5. The elastic seal 2 deforms under force and can form close contact with the pipeline, reducing the possibility of medium leakage; at the same time, the seal 2 can also adapt to different-shaped or -sized sealing pipes 11 and liquid cooling pipes 5 through its own deformation. Coupled with the elastic force generated by the extrusion of the seal 2, the seal 2 is kept closely attached to the outer peripheral surface of the pipeline, thereby improving the sealing effect. In addition, the elastic seal 2 has a certain elasticity and flexibility, and can maintain the sealing performance when subjected to vibration, increasing the adaptability of the sealing structure in different application scenarios.

[0042] Please refer to Figure 2 , in some embodiments, the pipeline sealing structure further includes a gasket 4. The gasket 4 is arranged on the side of the plate body 12 facing the cabin 6 and is connected to the plate body 12. The gasket 4 is arranged around the outer periphery of the through hole 121, and it fills the gap between the plate body 12 and the cabin 6 to seal the gap between them and reduce the possibility of medium leakage between the plate body 12 and the side wall of the cabin 6.

[0043] Please refer to Figure 2, in some embodiments, a sealing groove 123 is provided on one side of the plate body 12 facing the cabin 6. The inner contour of the sealing groove 123 is adapted to the outer contour of the sealing gasket 4, and at least part of the sealing gasket 4 is embedded in the sealing groove 123. Part or all of the sealing gasket 4 is embedded in the sealing groove 123. On the one hand, it can increase the contact area between the sealing gasket 4 and the plate body 12 and extend the path that the medium needs to pass through, thereby improving the sealing performance. On the other hand, the sealing groove 123 can form a support for the sealing gasket 4 to reduce the occurrence of displacement or falling off of the sealing gasket 4 during use.

[0044] Please also refer to Figure 2 , Figure 5 and Figure 6 , in some embodiments, the sealing plate 1 includes a plurality of sealing tubes 11. The plurality of sealing tubes 11 are arranged at intervals along the first direction X or the second direction Y. The number of through holes 121 and sealing members 2 is provided in plurality. Each sealing tube 11 corresponds to a through hole 121 and communicates with a pipe hole 61 through the through hole 121. Each sealing member 2 is sleeved on a sealing tube 11. Integrating a plurality of sealing tubes 11 on a plate body 12 can seal a plurality of liquid cooling tube channels through one sealing plate 1 when there are a plurality of pipe holes 61 in a local area of the cabin 6, which is convenient for operation. At this time, a plurality of waist-shaped holes 122 are distributed on both sides of the plurality of sealing tubes 11 along their arrangement direction to cooperate with the movement adjustment when the through holes 121 are aligned with the pipe holes 61.

[0045] Please also refer to Figure 1 and Figure 5 , in some embodiments, the material of the sealing member 2 is one of ethylene propylene diene monomer rubber, styrene butadiene rubber or silicone rubber. Different materials have different characteristics and can meet the use requirements of the energy storage cabinet under different working environments.

[0046] Please also refer to Figure 1 and Figure 5 , in some embodiments, the fixing member 3 includes a hose clamp. The hose clamp is integrally annular and has an adjusting device. The tightness of the hose clamp can be adjusted by turning the screw. The hose clamp is a conventional technical means in the art, and the specific structure of the hose clamp will not be described in detail here. The hose clamp is sleeved on the sealing member 2. Under the locking force of the hose clamp, the inner ring surface of the hose clamp can cooperate with the outer peripheral surface of the sealing member 2 to make the sealing member 2 uniformly fit on the outer peripheral surfaces of the sealing tube 11 and the liquid cooling tube 5, thereby increasing the sealing performance of the connection and the convenience of loading and unloading, and further improving the sealing efficiency of the liquid cooling tube channels. In some other embodiments, a snap ring or a hoop can also be used to connect the sealing member 2.

[0047] Correspondingly, an energy storage cabinet provided by an embodiment of the present application includes a cabinet body, a compartment 6, a liquid cooling pipe 5, and the pipeline sealing structure of the above embodiment. The compartment 6 is arranged in the cabinet body. The compartment 6 is provided with a pipe hole 61. The liquid cooling pipe 5 passes through the pipe hole 61. The pipeline sealing structure is used to seal the gap between the outer peripheral wall of the liquid cooling pipe 5 and the pipe hole 61 to prevent the medium from leaking through the pipe hole 61.
