[0002] As the total power of the energy storage system increases, it is difficult to transport the weight of a single cabin. Therefore, a complete system needs to be split into multiple prefabricated cabins for transportation and then installed by stacking them vertically at the destination.

[0050] Through the above-mentioned drawings, specific embodiments of the present application have been shown, and there will be more detailed descriptions hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed Description of the Embodiment

[0051] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0052] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data for analysis, stored data, displayed data, etc.) involved in the present application are all information and data authorized by the user or fully authorized by all parties, and the collection, storage, use, processing, transmission, provision, disclosure, and application of the relevant data and other processing all comply with the relevant laws, regulations, and standards of the relevant regions, take necessary confidentiality measures, do not violate public order and good customs, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0053] As the total power of the energy storage system increases, it becomes difficult to transport the weight of a single cabin. Therefore, a complete system needs to be split into multiple prefabricated cabins for transportation. After transporting to the destination, the cabins are installed side by side vertically. After the installation is completed, the wire harnesses of the two cabins (such as the liquid cooling pipelines, power lines, communication lines, secondary lines, fire communication lines, and fire power supply lines between the upper and lower boxes in the energy storage system) need to be connected.

[0054] The wire harness connection method of the prior art is to lead out wires from the bottom of the upper cabin and the top of the lower box respectively, and use cable waterproof joints (such as gland heads) to thread the wires. However, when using cable waterproof joints for wire threading in the prior art, two cable waterproof joints need to be installed separately for each wire leading out from the box body to seal the external parts of the upper and lower cabins once, which increases the installation time cost and requires a large installation space to be reserved in advance for wire threading and the installation of cable waterproof joints on both sides of the upper and lower cabins.

[0055] In addition, for special types of cables (such as corrugated pipes) and / or wall-piercing pipelines (such as liquid cooling pipes with flexible insulation layers), traditional gland heads are difficult to achieve effective sealing, that is, they do not meet the IP66 waterproof level required for energy storage in practice, thus increasing the protection cost for the wire harnesses and / or pipelines exposed to the external environment. For example, due to the uneven surface of the corrugated pipe, it is easy to cause incomplete sealing, and the flexible insulation layer of the liquid cooling pipe is prone to compression or deformation, thereby reducing the sealing effect and further increasing the installation difficulty in actual applications.

[0056] The through-cabin sealing method provided in this application is as follows: the bottom mounting flange of the upper box body is fully welded and installed at the bottom of the upper box, the top mounting flange of the lower box body is fully welded and installed at the top of the lower box body, and the installed upper box body is stacked above the installed lower box body. The wall-piercing pipe is fully welded and connected to the lower fastener to obtain a wall-piercing part. The pipelines to be passed through the cabin are loaded into the pipeline cavity in the wall-piercing pipe to physically isolate multiple pipelines. Then, the wall-piercing pipe loaded with multiple pipelines penetrates through the top mounting flange of the lower box body of the lower box, the bottom mounting flange of the upper box body of the upper box, and the upper sealing plate in sequence. The lower fastener of the wall-piercing part is locked and connected by bolts, so that the sealing rubber strip of the wall-piercing part on the lower fastener tightly seals the lower box body. The upper sealing plate is locked and connected to the bottom mounting flange of the upper box body by self-tapping screws, so that the upper box body sealing rubber strip on the bottom mounting flange of the upper box body tightly seals the upper box body. After the installation is completed, a diversion plate is installed between the upper box body and the lower box body to block water flow. For the leaked water flowing into the diversion plate, it is blocked by the water blocking strip at the top of the lower box body, thereby enhancing the sealing level after passing through the cabin while solving the problem of pipeline connection between cabins, and improving the safety and reliability of the energy storage system.

[0057] The following uses specific embodiments to elaborate in detail on the technical solutions of this application and how the technical solutions of this application solve the above-mentioned technical problems. These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will be described below in conjunction with the accompanying drawings.

[0058] Figure 1(a) is an exploded view I of the through-hull sealing system provided by this application. As shown in Figure 1(a), the through-hull sealing system is used to connect stacked boxes, and the through-hull sealing system includes: an upper sealing plate 11, an upper box bottom mounting flange 12, a lower box top mounting flange 14, and a wall-piercing member. Among them, the upper box bottom mounting flange is fully welded and installed at the bottom of the upper box; the lower box top mounting flange is fully welded and installed at the top of the lower box, and the upper box is stacked above the lower box; the wall-piercing member includes a wall-piercing pipe 151 and a lower fastener 152, and the wall-piercing pipe is fully welded to the lower fastener; a pipeline cavity is formed inside the wall-piercing pipe for loading multiple pipelines, so that the multiple pipelines penetrate through the hull in a co-cabin manner with physical isolation between the upper box and the lower box; the lower fastener is locked and connected to the lower box top mounting flange inside the lower box for sealing the lower box; the upper sealing plate is used to be locked and connected to the upper box bottom mounting flange after the wall-piercing pipe penetrates the upper box bottom mounting flange to seal the upper box.

[0059] Exemplarily, the above-mentioned multiple pipelines include but are not limited to various pipelines and lines such as liquid cooling pipelines, power lines, communication lines, secondary lines, fire communication lines, and fire power supply lines. Co-cabin penetration means that multiple pipeline media penetrate through the hull between the same upper box and the same lower box. By placing the above-mentioned multiple pipelines in the pipeline cavity of the wall-piercing pipe, the wall-piercing pipe is used as the sealing element body to physically isolate the above-mentioned multiple pipelines from the external environment, so that multiple pipelines are loaded through the wall-piercing pipe to penetrate through the hull from the lower box to the upper box in a co-cabin manner. Among them, the wall-piercing pipe, as the sealing element body, independently bears IP66 protection.

[0060] Optionally, the steps for the through-hull sealing system to connect stacked boxes include: fully welding and installing the lower box top mounting flange at the top of the lower box, fully welding and installing the upper box bottom mounting flange at the bottom of the upper box, stacking the upper box above the lower box; loading multiple pipelines through the pipeline cavity formed inside the wall-piercing pipe, so that the multiple pipelines penetrate through the hull in a co-cabin manner with physical isolation between the upper box and the lower box; among them, the wall-piercing pipe is fully welded to the lower fastener; locking and connecting the lower fastener to the lower box top mounting flange inside the lower box to seal the lower box; after the wall-piercing pipe penetrates the upper box bottom mounting flange, locking and connecting the upper sealing plate to the upper box bottom mounting flange inside the upper box to seal the upper box.

[0061] In a possible embodiment, as shown in Fig. 1(a), the top mounting flange of the lower box body is fully welded to the top 21 of the lower box body, and the bottom mounting flange of the upper box body is fully welded to the bottom 22 of the upper box body, so as to seal between the bottom mounting flange of the upper box body and the upper box body, and between the top mounting flange of the lower box body and the lower box body. The through-wall pipe 152 in the through-wall component is fully welded and connected to the lower fastener 151, so as to seal between the through-wall pipe and the lower fastener, thereby avoiding water leakage at the positions of the bottom mounting flange of the upper box body, the top mounting flange of the lower box body and the through-wall pipe. The upper box body with the flange installed is stacked on the lower box body, and multiple pipelines that need to be wired are loaded into the pipeline cavity of the through-wall pipe, so as to isolate the external environment and the multiple pipelines through the through-wall pipe. The through-wall pipe is sequentially penetrated and installed on the top mounting flange of the lower box body of the lower box body, the bottom mounting flange of the upper box body of the upper box body, and the upper sealing plate. After the through-wall pipe penetrates, the lower metal component is locked and connected to the top mounting flange of the lower box body to seal the space of the lower box body outside the lower fastener, and the upper sealing plate is locked and connected to the bottom mounting flange of the upper box body to seal the space of the upper box body outside the upper sealing plate.

[0062] In this embodiment, the external environment and multiple pipelines are physically isolated by the through-wall pipe, which solves the problem in the prior art that additional costs are required to protect the external leakage parts such as the wire harness, pipeline, and air pipe passing through the cabin. And wiring is performed between multiple box bodies, which improves the wiring rate of multiple pipelines and wires, reduces the requirements for the protection level of multiple pipelines, reduces the cost of passing through the cabin, eliminates the need to separately seal each wire, reduces space occupation, and further improves the safety and reliability of the energy storage system by enhancing the sealing performance of the box body.

[0063] Optionally, the through-cabin sealing system further includes a multi-stage waterproof subsystem, and the multi-stage waterproof subsystem includes a diversion plate, a top water-blocking strip of the lower box body, a through-wall component sealing rubber strip, and an upper box body sealing rubber strip; the diversion plate is installed between the outer periphery of the bottom of the upper box body and the outer periphery of the top of the lower box body, and is used to block part of the water from entering the gap after the upper box body and the lower box body are stacked; wherein, the upper edge of the diversion plate is connected to the outer periphery of the bottom of the upper box body, and the lower edge of the diversion plate is connected to the outer periphery of the top of the lower box body; the top water-blocking strip of the lower box body is connected to the top of the lower box body and is used to block the water entering the gap, and the installation position of the top water-blocking strip of the lower box body is between the outer side of the flange surface of the top mounting flange of the lower box body and the inner side of the diversion plate; the through-wall component sealing rubber strip is installed above the lower fastener and is used to seal and protect the lower box body through compression deformation when the lower fastener is locked and connected to the top mounting flange of the lower box body; the upper box body sealing rubber strip is installed above the bottom mounting flange of the upper box body and is used to seal and protect the upper box body through compression deformation when the upper sealing plate is locked and connected to the bottom mounting flange of the upper box body.

[0064] Optionally, the steps of connecting the through-hull sealing system to the stacked boxes further include: installing a flow deflector between the bottom periphery of the upper box and the top periphery of the lower box to block part of the water from entering the gap after the upper box and the lower box are stacked; wherein, the upper edge of the flow deflector is connected to the bottom periphery of the upper box, and the lower edge of the flow deflector is connected to the top periphery of the lower box; installing a water-blocking strip at the top of the lower box between the outer flange surface of the flange installed on the top of the lower box and the inner side of the flow deflector, and connecting the water-blocking strip at the top of the lower box to the flange surface of the flange installed on the top of the lower box to block the water entering the gap; installing a sealing strip for the wall-piercing part above the lower fastener to provide sealing protection for the lower box through the compression deformation of the sealing strip for the wall-piercing part when the lower fastener is locked and connected to the flange of the flange installed on the top of the lower box; installing a sealing strip for the upper box above the flange installed at the bottom of the upper box to provide sealing protection for the upper box through the compression deformation of the sealing strip for the upper box when the upper sealing plate is locked and connected to the flange of the flange installed at the bottom of the upper box.

[0065] In a possible embodiment, the flow deflector of the multi-stage waterproof subsystem is the first-stage waterproof unit, the water-blocking strip at the top of the lower box is the second-stage waterproof unit, and the sealing strips for the wall-piercing part and the sealing strip for the upper box are the third-stage waterproof unit. As shown in Fig. 1(b), the upper edge of the flow deflector of the multi-stage waterproof subsystem is installed on the periphery of the bottom 22 of the upper box, and the lower edge of the flow deflector is installed on the periphery of the top 21 of the lower box to block part of the water flow from entering the through-hull gap between the upper box and the lower box. The lower edge of the water-blocking strip 13 at the top of the lower box of the multi-stage waterproof subsystem is installed on the top 21 of the lower box (as Figure 2 shown), and is located between the outer flange surface of the flange installed on the top of the lower box and the inner side of the flow deflector to further block the water leakage that the flow deflector fails to block successfully. By fixing the sealing strip for the wall-piercing part on the lower fastener, when the lower fastener is locked and connected to the flange surface of the flange installed on the top of the lower box, the sealing strip for the wall-piercing part fixed on the lower fastener is compressed, so that the compressed and deformed sealing strip for the wall-piercing part enhances the sealing performance of the lower box. By fixing the sealing strip for the upper box on the flange surface of the flange installed at the bottom of the upper box, when the upper sealing plate is locked and connected to the flange surface of the flange installed at the bottom of the upper box, the sealing strip for the upper box fixed on the flange surface of the flange installed at the bottom of the upper box is compressed, so that the compressed and deformed sealing strip for the upper box enhances the sealing performance of the upper box, thereby blocking the water leakage that the water-blocking strip at the top of the lower box fails to block.

[0066] In this embodiment, the flow deflector blocks the water flow between the box gaps, and a water-blocking strip at the top of the lower box is arranged inside the flow deflector to secondarily block a small amount of water leakage entering the box gaps. Also, sealing strips are arranged at the locking joints to enhance the sealing performance of the box and further block the water leakage, thereby enhancing the sealing performance and improving the waterproof level.

[0067] Optionally, the through-hull sealing system further includes a drainage subsystem, which includes a drain pipe and a drainage joint; the drainage joint is installed at the reserved drainage opening of the lower fastener; one end of the drain pipe is connected to the drainage joint, and the other end is connected to the floor drain at the bottom of the hull, for draining the water that enters the sealing strip of the through-wall component.

[0068] Optionally, the steps of connecting the through-hull sealing system to the stacked boxes further include: installing a drainage joint at the reserved drainage opening of the lower fastener; inserting one end of the drain pipe into the drainage joint for connection, and connecting the other end of the drain pipe to the floor drain at the bottom of the hull, to drain the water that enters the sealing strip of the through-wall component.

[0069] In a possible embodiment, a reserved drainage opening 1512 (as shown in Fig. 3(a)) is provided on the lower fastener, the drainage joint is connected to the above-mentioned reserved drainage opening, one end of the drain pipe is connected to the drainage joint, and the other end is connected to the floor drain at the bottom of the hull, to drain the water blocked by the sealing strip of the through-wall component to the floor drain.

[0070] In this embodiment, by providing a drainage subsystem, the water blocked by the sealing strip of the through-wall component is effectively drained in time, preventing the sealing strip of the through-wall component from being soaked for a long time, enhancing the multi-scenario applicability of the through-hull sealing system, and further improving the stability and safety of the energy storage system.

[0071] Optionally, the through-hull sealing system further includes a compensation sealing subsystem, which includes bolts and self-tapping screws; a first opening is formed in the middle of the mounting flange at the top of the lower box, and the inner diameter of the first opening exceeds the outer diameter of the through-wall pipe by a first preset value; a second opening is formed in the middle of the mounting flange at the bottom of the upper box, and the inner diameter of the second opening exceeds the outer diameter of the through-wall pipe by a second preset value; wherein, the second preset value is greater than the first preset value, for when the upper box and the lower box are stacked and misaligned, the through-wall pipe penetrates from the mounting flange at the top of the lower box to the mounting flange at the bottom of the upper box; the bolts are used for locking and connecting the welding nut on the flange surface of the lower fastener and the mounting flange at the top of the lower box, to seal the space outside the through-wall pipe in the first opening; the self-tapping screws are used for, after the through-wall pipe passes through the third opening formed in the middle of the upper sealing plate, locking and connecting the upper sealing plate and the flange surface of the mounting flange at the bottom of the upper box, to seal the space outside the through-wall pipe in the second opening; the outer diameter of the flange surface of the mounting flange at the bottom of the upper box is greater than the outer diameter of the upper sealing plate.

[0072] Optionally, the steps of connecting the through-hull sealing system to the stacked boxes further include: when the upper box and the lower box are stacked and misaligned, penetrating through the first opening in the middle of the flange at the top of the lower box to the second opening in the middle of the flange at the bottom of the upper box through the through-wall pipe; wherein, the inner diameter of the first opening exceeds the outer diameter of the through-wall pipe by a first preset value; the inner diameter of the second opening exceeds the outer diameter of the through-wall pipe by a second preset value, and the second preset value is greater than the first preset value; locking and connecting the lower fastener to the welding nut on the flange surface of the top mounting flange of the lower box through bolts to seal the space outside the through-wall pipe in the first opening; after the through-wall pipe passes through the third opening formed in the middle of the upper sealing plate, locking and connecting the upper sealing plate to the flange surface of the bottom mounting flange of the upper box through self-tapping screws to seal the space outside the through-wall pipe in the second opening; the outer diameter of the flange surface of the bottom mounting flange of the upper box is greater than the outer diameter of the upper sealing plate.

[0073] Exemplarily, the difference between the outer diameter of the through-wall pipe and the second opening 122 in the middle of the bottom mounting flange of the upper box (as shown in Figure 4 ), is greater than the difference between the outer diameter of the through-wall pipe and the first opening 143 in the middle of the top mounting flange of the lower box (as shown in Figure 5 ), so as to increase the probability that the through-wall pipe effectively penetrates the second opening in the middle of the bottom mounting flange of the upper box when the upper box is misaligned and stacked above the lower box (for example, there is an axial displacement tolerance of ±50 mm and / or a radial displacement tolerance of ±20 mm between the upper box and the lower box), reduce the requirement for stacking accuracy, and further improve the through-hull efficiency.

[0074] In a possible embodiment, bolts 16 (as shown in Figures 1(a) and 1(b)) pass through the bolt holes 1511 on the lower fastener (as shown in Figures 3(a) and 3(b)), and are connected to the welding nuts 141 (as shown in Figure 5 ) on the flange surface 142 of the top mounting flange 14 of the lower box (mounted on the top 21 of the lower box) to obtain the locked connection between the lower fastening plate 151 and the top mounting flange 14 of the lower box, so that the through-wall part sealing strip fixed on the lower fastening plate is pressed, thereby strengthening the sealing of the space of the lower box outside the through-wall pipe. The upper sealing plate 11 is locked and connected to the flange surface 121 of the bottom mounting flange 12 of the upper box (as shown in Figure 4 ) through self-tapping screws, so that the upper box body sealing strip fixed on the bottom mounting flange of the upper box is pressed, thereby strengthening the sealing of the space of the upper box outside the through-wall pipe. Wherein, the outer diameter of the flange surface of the bottom mounting flange of the upper box is greater than the outer diameter of the upper sealing plate to ensure that the self-tapping screws can lock and connect the upper sealing plate and the flange surface of the bottom mounting flange of the upper box, and the position of the self-tapping screw on the bottom mounting flange of the upper box is inside the upper box, so the position of the self-tapping screw does not need to be sealed.

[0075] In this embodiment, by setting a relatively large second opening in the middle of the mounting flange at the bottom of the upper box body, when the upper box body is stacked on the lower box body without alignment, the through-wall pipe can penetrate into the second opening in the middle of the mounting flange at the bottom of the upper box body, and a relatively large flange surface of the mounting flange at the bottom of the upper box body is set to dynamically compensate for the installation error when stacking without alignment, reduce the precision requirements for the butt joint installation of the box bodies, and improve the reliability and convenience of passing through the cabin.

[0076] Exemplarily, the difference between the outer diameter of the through-wall pipe and the third opening 111 in the middle of the upper sealing plate (as Figure 6 shown) is 2 mm.

[0077] Optionally, the space in the third opening other than the through-wall pipe is set to be filled with sealant, which is used to supplement the seal between the upper box body and the lower box body after the upper sealing plate is tightly connected to the flange surface of the mounting flange at the bottom of the upper box body.

[0078] Optionally, the step of connecting the stacked box bodies by the through-cabin sealing system further includes: after the upper sealing plate is tightly connected to the flange surface of the mounting flange at the bottom of the upper box body, filling the space in the third opening other than the through-wall pipe with sealant to supplement the seal between the upper box body and the lower box body.

[0079] In this embodiment, after the upper sealing plate is tightly connected to the flange surface of the mounting flange at the bottom of the upper box body, the gap between the two is filled with sealant to supplement the seal of the gap and enhance the sealing performance of the box body.

[0080] In a possible embodiment, Figure 7 is the front view of the assembled through-cabin sealing system provided by this application. As Figure 7 shown, the through-wall pipe 152 of the through-wall part sequentially penetrates the top mounting flange 14 of the lower box body, the top 21 of the lower box body (and the lower box body top water stop strip 13 installed on the top of the lower box body), the bottom 22 of the upper box body, the upper box body bottom mounting flange 12 and the upper sealing plate 11. After penetration, bolts 16 pass through the bolt holes on the lower fastener and are connected to the welding nuts on the flange surface of the top mounting flange of the lower box body, so that the lower fastening plate is tightly connected to the top mounting flange of the lower box body, thereby strengthening the sealing performance of the lower box body by pressing the through-wall part sealant strip fixed on the lower fastening plate. The upper sealing plate is tightly connected to the flange surface of the upper box body bottom mounting flange by self-tapping screws, so that the upper box body sealant strip fixed on the upper box body bottom mounting flange is pressed, and the gap between the upper sealing plate and the through-wall pipe is filled with sealant, thereby strengthening the sealing performance of the upper box body.

[0081] Optionally, between the outer side of the flange surface of the flange installed on the top of the lower box body and the inner side of the flow guide plate, connect the water blocking strip at the top of the lower box body to the top of the lower box body, and install the flow guide plate on the periphery of the top of the lower box body, so as to initially block the water that may flow through the box body gap through the flow guide plate, and secondarily block the water that fails to be initially blocked through the water blocking strip at the top of the lower box body. The water that fails to be secondarily blocked is tertiarily blocked by the sealing strip in the above-mentioned embodiment to enhance the sealing performance of the box body. For the water blocked by the sealing strip of the wall-piercing part, the water flows into the floor drain through the reserved drain port on the lower fastening plate, the drain joint and the drain pipe, so as to timely discharge the small amount of water leakage that may occur, avoid the long-term immersion of the sealing strip of the wall-piercing part, and further improve the stability and safety of the energy storage system.
