Description

Technical Field

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

[0002] The alternating heating and cooling of pure lithium-ion batteries during charging and discharging in energy storage containers is a significant concern, especially in 1P rate energy storage systems. As the charge / discharge rate increases, system heat generation also increases, leading to a greater demand for liquid cooling units. During temperature changes, substantial amounts of condensate are generated, accumulating at the bottom of the energy storage container. This accumulated condensate can corrode the structural panels, and if it reaches a certain level, it will affect the normal operation of the system.

[0003] Conventional energy storage containers do not have drainage holes designed for the bottom plate, making it difficult for condensate to drain. Condensate is prone to accumulate during the operation of the energy storage system. Condensate accumulation can affect the insulation performance of the system, and long-term accumulation can affect the normal operation of the energy storage system. In addition, condensate can accelerate the corrosion of the bottom plate material, affecting the product's life cycle. Utility Model Content

[0004] The main purpose of this utility model is to propose a drainage structure for an energy storage container and an energy storage container, which aims to prevent condensate accumulation, ensure the normal operation of the energy storage system, and improve the service life of the energy storage container.

[0005] To achieve the above objectives, the energy storage container drainage structure proposed in this utility model includes a base, a guide plate, and a drain pipe. The base forms an installation groove, and the bottom wall of the installation groove is provided with a first drainage hole. The guide plate is disposed in the installation groove and connects to the two opposite inner side walls of the installation groove. The guide plate has a guide slope that is inclined along the groove opening of the installation groove to the bottom wall of the installation groove. The guide slope is provided with a second drainage hole at the point closest to the bottom wall of the installation groove. The drain pipe connects the first drainage hole and the second drainage hole.

[0006] In one embodiment, the second drain hole is arranged vertically corresponding to the first drain hole.

[0007] In one embodiment, the distance from the guide slope to the bottom wall of the mounting groove gradually decreases along the length of the mounting groove.

[0008] In one embodiment, the guide slope includes a first guide surface and a second guide surface. The second guide surface is connected to the inner wall of the mounting groove, and the first guide surface and the side of the second guide surface opposite to the inner wall of the mounting groove are connected. The distance from the first guide surface to the bottom wall of the mounting groove gradually decreases along the direction from the center line of the mounting groove to the inner wall of the mounting groove, and the distance from the second guide surface to the bottom wall of the mounting groove gradually increases along the direction from the center line of the mounting groove to the inner wall of the mounting groove. The second drain hole is located at the connection between the first guide surface and the second guide surface.

[0009] In one embodiment, the guide plate further has a central plane that extends along the center line of the mounting groove and is connected to the first guide surface.

[0010] In one embodiment, the energy storage container drainage structure further includes a plurality of connecting walls, which are spaced apart within the mounting groove, and each connecting wall connects to two opposite inner sidewalls of the mounting groove; the energy storage container drainage structure includes at least two guide plates, and each guide plate connects to two adjacent connecting walls.

[0011] In one embodiment, the energy storage container drainage structure further includes at least two fixing ribs; each pair of fixing ribs is respectively provided on two opposite inner sidewalls of the mounting groove; or, each pair of fixing ribs is respectively provided on opposite sidewalls of two adjacent connecting walls; each guide plate overlaps on two oppositely provided fixing ribs.

[0012] In one embodiment, the fixing rib includes an overlapping section and two reinforcing sections. The overlapping section is arranged parallel to the guide slope. The two reinforcing sections are respectively connected to both ends of the overlapping section, and each reinforcing section extends along the direction from the opening of the mounting groove to the bottom wall of the mounting groove.

[0013] In one embodiment, the connecting wall is a hollow square tube structure.

[0014] This utility model also proposes an energy storage container, which includes the energy storage container drainage structure as described in any of the above embodiments.

[0015] The drainage structure of this energy storage container includes a base, a guide plate, and a drain pipe. The base has an installation groove, and the bottom wall of the installation groove has a first drainage hole. The guide plate is located in the installation groove and connects to the two opposite inner side walls of the installation groove. The guide plate has a guide slope that is inclined from the groove opening to the bottom wall of the installation groove. A second drainage hole is located at the point on the guide slope closest to the bottom wall of the installation groove. The drain pipe connects the first drainage hole and the second drainage hole. By setting the first drainage hole and the second drainage hole on the guide plate and the base respectively, and connecting the first drainage hole and the second drainage hole with the drain pipe, the upper space of the base is connected to the lower space of the base. When condensation occurs inside the energy storage container, the condensation flows from the second drainage hole into the drain pipe under the guidance of the guide plate and is discharged from the energy storage container through the first drainage hole, avoiding the accumulation of condensation that could affect the normal operation of the energy storage system.

[0037] This utility model proposes a drainage structure 100 for an energy storage container.

[0038] Please see Figure 2 , Figure 3 and Figure 8 In one embodiment of this utility model, the energy storage container drainage structure 100 includes a base 1, a guide plate 2, and a drain pipe 3. The base 1 forms an installation groove 1a, and the bottom wall of the installation groove 1a is provided with a first drainage hole 1b. The guide plate 2 is disposed in the installation groove 1a and connects the two opposite inner side walls of the installation groove 1a. The guide plate 2 has a guide slope 21 that is inclined along the groove opening of the installation groove 1a to the bottom wall of the installation groove 1a. The guide slope 21 is provided with a second drainage hole 2a at the part closest to the bottom wall of the installation groove 1a. The drain pipe 3 connects the first drainage hole 1b and the second drainage hole 2a.

[0039] In this embodiment, the base 1 is located at the bottom of the energy storage container, serving as the installation foundation for the entire energy storage container. The base 1 includes a base plate and two parallel, spaced-apart support walls. An installation groove 1a is formed between the two support walls and the base plate. A guide plate 2 is located between the two support walls and connects them. Connecting walls 4 are provided at both ends of the base plate, perpendicular to and connecting the two support walls. The guide plate 2 can be configured such that the connecting walls 4 at both ends connect to the two support walls, i.e., the guide plate 2 closes the installation groove 1a, preventing condensate from seeping into the gap between the guide plate 2 and the inner wall of the installation groove 1a. It is understood that, while meeting the support strength requirements of the base 1, the connecting walls 4 and the support walls can be designed as hollow structures to reduce weight and save manufacturing materials; for example, square tubing can be used. The guide plate 2 has a guide slope 21 inclined along the opening of the mounting groove 1a to the bottom wall of the mounting groove 1a. A second drain hole 2a is provided at the lowest point of the guide slope 21, and a first drain hole 1b is provided on the bottom plate. A floor drain pipe 3 is also provided in the mounting groove 1a. One end of the floor drain pipe 3 is fixedly connected to the periphery of the first drain hole 1b and communicates with the first drain hole 1b. The other end of the floor drain pipe 3 abuts against the periphery of the second drain hole 2a and communicates with the second drain hole 2a. In this way, the floor drain pipe 3 connects the first drain hole 1b and the second drain hole 2a, that is, the floor drain pipe 3 connects the upper and lower space of the base 1. Condensate collects along the guide slope 21 in the floor drain pipe 3 and is discharged from the bottom plate, preventing condensate accumulation from affecting the normal operation of the energy storage system and preventing condensate accumulation from causing corrosion of the bottom plate. The support wall, connecting wall 4 and guide plate 2 can also be made of metal materials with good corrosion resistance or treated with anti-corrosion coating.

[0040] The energy storage container drainage structure 100 of this embodiment provides a guide plate 2 inside the base 1, and provides a first drainage hole 1b and a second drainage hole 2a on the guide plate 2 and the base 1 respectively. The first drainage hole 1b and the second drainage hole 2a are connected by a floor drain pipe 3, so that the upper space of the base 1 is connected to the lower space of the base 1. When condensate appears inside the energy storage container, the condensate flows from the second drainage hole 2a into the floor drain pipe 3 under the guidance of the guide plate 2 and is discharged from the energy storage container through the first drainage hole 1b. This avoids the accumulation of condensate from affecting the normal operation of the energy storage system and prevents the bottom plate from being corroded due to the accumulation of condensate.

[0041] Further, please refer to Figure 5 , Figure 8 and Figure 9 In one embodiment of this utility model, the second drainage hole 2a and the first drainage hole 1b are arranged vertically in correspondence.

[0042] In this embodiment, the second drain hole 2a and the first drain hole 1b are arranged vertically to minimize the distance between them, thereby improving the drainage rate and saving material usage for the drain pipe 3. In addition, the arrangement of the drain pipe 3 is simplified. The vertical arrangement of the second drain hole 2a and the first drain hole 1b allows the drain pipe 3 to be set as a straight pipe. The drain pipe 3 can be made of corrosion-resistant metal material and installed on the base plate by welding or screwing.

[0043] Further, please refer to Figures 6 to 8 In one embodiment of this utility model, the distance from the guide slope 21 to the bottom wall of the mounting groove 1a gradually decreases along the length of the mounting groove 1a.

[0044] In this embodiment, the distance from the guide slope 21 to the bottom wall of the mounting groove 1a gradually decreases along the length of the mounting groove 1a, so that one side of the guide slope 21 is higher than the other side along the length of the mounting groove 1a. The lowest point of the guide slope 21 is provided with a second drain hole 2a, which facilitates the guide slope 21 to guide the water flow to collect in the second drain hole 2a.

[0045] Further, please refer to Figure 2 and Figure 9 In one embodiment of this utility model, the guide slope 21 includes a first guide surface 211 and a second guide surface 212. The second guide surface 212 is connected to the inner wall of the mounting groove 1a, and the first guide surface 211 and the second guide surface 212 are connected to the side of the second guide surface 212 that is away from the inner wall of the mounting groove 1a. The distance from the first guide surface 211 to the bottom wall of the mounting groove 1a gradually decreases along the direction from the center line of the mounting groove 1a to the inner wall of the mounting groove 1a, and the distance from the second guide surface 212 to the bottom wall of the mounting groove 1a gradually increases along the direction from the center line of the mounting groove 1a to the inner wall of the mounting groove 1a. The second drain hole 2a is provided at the connection between the first guide surface 211 and the second guide surface 212.

[0046] In this embodiment, along the length of the mounting groove 1a, the distances from the first guide surface 211 and the second guide surface 212 to the bottom wall of the mounting groove 1a gradually decrease along the length of the mounting groove 1a. Along the width of the mounting groove 1a, the distance from the first guide surface 211 to the bottom wall of the mounting groove 1a gradually decreases along the direction from the center line of the mounting groove 1a to the inner wall of the mounting groove 1a, while the distance from the second guide surface 212 to the bottom wall of the mounting groove 1a gradually increases along the direction from the center line of the mounting groove 1a to the inner wall of the mounting groove 1a. Thus, along the width of the mounting groove 1a, the guide slope 21 is divided into a first guide surface 211 and a second guide surface 212 with opposite inclination directions. The horizontal span of each guide surface is relatively smaller than the original horizontal span of the entire guide slope 21, thereby increasing the slope of the first guide surface 211 and the second guide surface 212 along the width of the mounting groove 1a and improving the water flow convergence rate. Based on this principle, the guide plate 2 can be divided into two symmetrical parts along the centerline of the mounting groove 1a. Each part has a first guide surface 211 and a second guide surface 212 to further increase the slope of each guide surface and improve the efficiency of water flow collection. It should be noted that the connection point between the first guide surface 211 and the second guide surface 212 is the lowest point of the entire guide slope 21 in the width direction of the mounting groove 1a. Therefore, the second drain hole 2a is located at the connection point of the first guide surface 211 and the second guide surface 212 to improve drainage efficiency. Since the guide plate 2 is a single unit, placing the second drain hole 2a at the connection point of the first guide surface 211 and the second guide surface 212 can also prevent water flow from accumulating in the gap between the guide plate 2 and the side wall of the mounting groove 1a, reducing the sealing requirements of the gap between the guide plate 2 and the side wall of the mounting groove 1a and reducing production difficulty.

[0047] Further, please refer to Figures 1 to 2 In one embodiment of the present invention, the guide plate 2 further has a central plane 22, which extends along the center line of the mounting groove 1a and is connected to the first guide surface 211.

[0048] In this embodiment, a central plane 22 is provided on the guide plate 2 at the center line of the mounting groove 1a. A first guide surface 211 and a second guide surface 212 are respectively provided on both sides of the central plane 22. The presence of the central plane 22 can reduce the span of the first guide surface 211, increase the slope of the first guide surface 211, and reduce the bending angle at the center, preventing the guide plate 2 from being excessively bent and cracked.

[0049] Further, please refer to Figures 1 to 2In one embodiment of the present invention, the energy storage container drainage structure 100 further includes a plurality of connecting walls 4, which are spaced apart in the mounting groove 1a, and each connecting wall 4 connects to two opposite inner sidewalls of the mounting groove 1a; the energy storage container drainage structure 100 includes at least two guide plates 2, and each guide plate 2 connects to two adjacent connecting walls 4.

[0050] In this embodiment, multiple connecting walls 4 are spaced apart within the mounting groove 1a. Each connecting wall 4 connects to two opposite inner sidewalls of the mounting groove 1a, thereby enhancing the connection between the two opposite inner sidewalls of the mounting groove 1a and ensuring the supporting strength of the base 1 for the upper structure of the energy storage container. Furthermore, along the length of the mounting groove 1a, multiple connecting walls 4 are spaced apart, dividing the mounting groove 1a into multiple spaces. At this point, multiple guide plates 2 are installed, each guide plate 2 connecting to two adjacent connecting walls 4. This reduces the span of the guide plate 2 along the length of the mounting groove 1a, lowers the strength requirements of the mounting plate, reduces the size of the mounting plate, and reduces the processing and manufacturing difficulty of the mounting plate.

[0051] Further, please refer to Figure 2 , Figure 4 and Figure 5 In one embodiment of the present invention, the energy storage container drainage structure 100 further includes at least two fixed ribs 5; each pair of fixed ribs 5 is respectively provided on the two opposite inner side walls of the mounting groove 1a; or, each pair of fixed ribs 5 is respectively provided on the opposite side walls of two adjacent connecting walls 4; each guide plate 2 overlaps on the two oppositely provided fixed ribs 5.

[0052] In this embodiment, the energy storage container drainage structure 100 also includes multiple connecting walls 4, which are spaced apart in the mounting groove 1a. Each connecting wall 4 connects to two opposite inner sidewalls of the mounting groove 1a. The multiple connecting walls 4 divide the mounting groove 1a into multiple spaces. Each pair of fixing ribs 5 are respectively provided on two opposite inner sidewalls of the mounting groove 1a, or on opposite sidewalls of two adjacent connecting walls 4. Each guide plate 2 overlaps on two oppositely provided fixing ribs 5. The fixing ribs 5 are pre-installed on the connecting walls 4 or the sidewalls of the mounting groove 1a to facilitate the positioning of the guide plate 2 during installation and to provide support for the guide plate 2 after installation, thereby enhancing the load-bearing capacity of the guide plate 2.

[0053] Further, please refer to Figure 5 In one embodiment of the present invention, the fixing rib 5 includes an overlapping section 52 and two reinforcing sections 51. The overlapping section 52 is arranged parallel to the guide slope 21. The two reinforcing sections 51 are respectively connected to the two ends of the overlapping section 52. Each reinforcing section 51 extends along the direction from the opening of the mounting groove 1a to the bottom wall of the mounting groove 1a.

[0054] In this embodiment, the overlapping section 52 is adapted to the installed guide plate 2, facilitating the positioning of the guide plate 2 during installation and its support after installation. Therefore, the overlapping section 52 is arranged parallel to the guide slope 21. Two reinforcing sections 51 are respectively connected to both ends of the overlapping section 52. Each reinforcing section 51 extends along the direction from the opening of the mounting groove 1a to the bottom wall of the mounting groove 1a, that is, the reinforcing section 51 extends along the direction of the gravity applied by the guide plate 2 to the overlapping section 52. The addition of the reinforcing section 51 enhances the load-bearing capacity of the fixing rib 5 and strengthens the support of the fixing rib 5 for the guide plate 2.

[0055] Further, please refer to Figures 7 to 8 In one embodiment of this utility model, the connecting wall 4 is a hollow square tube structure. In this embodiment, the connecting wall 4 serves to strengthen the connection between the two side walls of the mounting groove 1a and divide the mounting groove 1a into multiple spaces to reduce the structural size of the guide plate 2. Therefore, while ensuring that the connecting wall 4 can meet the connection strength requirements, the connecting wall 4 can adopt a hollow square tube structure to reduce its weight and material costs.

[0056] This utility model also proposes an energy storage container, which includes the energy storage container drainage structure 100 as described in any of the above embodiments. Since this energy storage container adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
