Description

Technical Field

[0001] This application relates to the field of energy storage container technology, specifically to a container bottom structure and an energy storage container. Background Technology

[0002] During the actual use of energy storage containers, liquid water can easily be generated inside the container. It is necessary to drain the liquid water from the outside of the container in a timely manner to avoid adverse effects on the normal operation of critical equipment such as internal batteries.

[0003] In related technologies, a drainage channel is installed on one side of the tank bottom to achieve drainage. However, the tank bottom is usually arranged with multiple crossbeams, which can obstruct the continuous arrangement of the drainage channel and make it difficult for liquid water to collect and be discharged. Utility Model Content

[0004] In view of this, this application provides a container bottom structure and an energy storage container to solve or improve the problem that when a drainage channel is installed on one side of the container bottom, the crossbeam will obstruct the continuous arrangement of the drainage channel, making it inconvenient for the collection and discharge of liquid water.

[0005] In a first aspect, this application provides a box bottom structure having a first direction, a second direction, and a third direction that are perpendicular to each other. The box bottom structure includes a plurality of crossbeams and a water guide. The plurality of crossbeams are spaced apart along the first direction, and a bottom plate is provided between two adjacent crossbeams. At least one end of each crossbeam along the second direction is provided with a groove. The water guide extends along the first direction and passes through the plurality of grooves in sequence, and a drainage groove is provided on the water guide.

[0006] Beneficial effects: By creating grooves at the ends of each crossbeam and having the water guide pass through multiple grooves sequentially, the crossbeams are prevented from obstructing the drainage channel. This creates an uninterrupted drainage channel in the first direction, facilitating the removal of liquid water from the container. Furthermore, this design reduces the number of openings in the floor plate, maintaining its structural strength and increasing its load-bearing capacity.

[0007] In one alternative embodiment, the end of the base plate along the second direction is hermetically connected to the water guide; the water guide is in a sealing fit with the side of the groove along the second direction.

[0008] Beneficial effects: The water guide component and the end face of the base plate along the first direction and the side of the groove together form the side of the drainage groove, thereby eliminating the side of the water guide component near the end face of the base plate and the side of the groove, reducing the amount of material used for the water guide component and lowering production costs.

[0009] In one alternative embodiment, the plurality of crossbeams are provided with side beams on both sides along the second direction, and the two ends of the crossbeams are respectively connected to two side beams, and the water guide is fitted to the end face of the side beam facing the bottom plate.

[0010] Beneficial effects: The water guide is designed to fit snugly against the side beams, allowing liquid water inside the container to drain out from one side of the container's bottom structure. Simultaneously, condensate generated on the side beams can enter the drainage channel, facilitating the removal of condensate from the side beams from the container.

[0011] In one alternative embodiment, the water guide includes a bottom water guide plate and a side water guide plate connected together. The bottom water guide plate is sealed to the end of the bottom plate along one side of the second direction, and the bottom water guide plate is sealed to the side of the groove along one side of the second direction. The side water guide plate is connected to the side beam.

[0012] Beneficial effects: The bottom guide plate can support the liquid water accumulated in the water guide component, allowing the liquid water to flow along the pre-designed drainage channel direction. The side guide plates are connected to the side beams, which improves the connection strength between the water guide component and the side beams, and facilitates the flow of condensate generated on the side beams along the side guide plates to the bottom guide plate.

[0013] In one alternative embodiment, a skin layer is provided on the top surface of the base plate, the skin layer having a first end and a second end opposite to each other along the second direction, the first end of the skin layer being close to the water guide, and the height of the second end of the skin layer along the third direction being higher than the height of the first end of the skin layer along the third direction.

[0014] Beneficial effects: An inclined skin layer is provided on the top surface of the base plate. This skin layer can guide liquid water at the bottom of the tank to the drainage components, improving the efficiency of liquid water drainage. Furthermore, the skin layer does not require damage to the structure of the base plate. While ensuring effective drainage at the bottom of the tank, it can also maintain the structural strength of the base plate, reducing the operating cost of the base plate.

[0015] In one optional embodiment, a drainage channel is provided on the bottom plate, the drainage channel is located at one end of the water guide member along the first direction, the outlet of the drainage trough is connected to the inlet of the drainage channel, and the outlet of the drainage channel extends to the outside of the container; the bottom water guide plate has a first end and a second end opposite to each other along the first direction, the first end of the bottom water guide plate is close to the drainage channel, and the height of the second end of the bottom water guide plate along the third direction is higher than the height of the first end of the bottom water guide plate along the third direction.

[0016] Beneficial effects: The drainage channel is located at one end of the water guide component. This allows liquid water from the drainage trough to be discharged from the container through the drainage channel, reducing the number of drainage channels required on the floor and thus maintaining the structural strength of the floor. Furthermore, the bottom water guide plate is inclined along the first direction, facilitating the diversion of liquid water collected in the drainage trough to the drainage channel, further improving drainage efficiency.

[0017] In one alternative embodiment, a pad is provided between the bottom water guide plate and the top surface of the crossbeam, and the pad is connected to the bottom water guide plate and the crossbeam respectively.

[0018] Beneficial effect: By setting the pad, the bottom water guide plate can be tilted in the first direction, which makes it easier to guide the liquid water collected by the water guide to the drainage channel.

[0019] In one alternative embodiment, the crossbeam has a cavity inside, and a sealing member is provided on the groove. The sealing member is connected to the crossbeam and is used to prevent the cavity from communicating with the water guide.

[0020] Beneficial effect: By installing a closure on the crossbeam, liquid water inside the water guide can be prevented from entering the cavity of the crossbeam, thereby improving the drainage effect of the water guide.

[0021] Secondly, this application provides an energy storage container, including the bottom structure described in any of the above claims.

[0022] Beneficial effects: This energy storage container features the aforementioned bottom structure. By creating grooves at the ends of each crossbeam and allowing water guides to pass through multiple grooves sequentially, it facilitates the drainage of liquid water from inside the container. Furthermore, it reduces the number of openings on the bottom plate, maintaining its structural strength and enhancing its load-bearing capacity.

[0023] In one alternative embodiment, a battery holder is also included, which is disposed on the crossbeam.

[0024] Beneficial effects: By mounting the battery bracket on the crossbeam, and because the top surface of the crossbeam is higher than the top surface of the base plate, a gap is formed between the battery module on the battery bracket and the base plate, effectively preventing the battery module from coming into contact with liquid water on the base plate and ensuring the operational safety of the battery module. Furthermore, the crossbeam has high structural strength, preventing the base plate from deforming or being damaged by directly bearing the weight of the battery bracket. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] The following is combined with Figures 1 to 9 This describes an embodiment of the present application.

[0030] According to an embodiment of this application, in a first aspect, a box bottom structure is provided, having a first direction X, a second direction Y, and a third direction Z that are perpendicular to each other. The box bottom structure includes a plurality of crossbeams 1 and a water guide 4. The plurality of crossbeams 1 are spaced apart along the first direction X, and a bottom plate 2 is provided between two adjacent crossbeams 1. At least one end of each crossbeam 1 along the second direction Y is provided with a groove 3. The water guide 4 extends along the first direction X and passes through the plurality of grooves 3 in sequence, and a drainage groove 100 is provided on the water guide 4.

[0031] First, it should be noted that, as Figure 1 As shown, in this embodiment, the first direction X is the length direction of the container, that is... Figure 1 The left and right directions of the container, and the second direction Y is the width direction of the container, that is... Figure 1 The container's front-to-back direction is defined by the third direction Z, which represents the container's height. Figure 1 The vertical direction of the container. Of course, those skilled in the art can adjust the specific reference positions of the first direction X, the second direction Y, and the third direction Z according to actual needs.

[0032] It is understood that the aforementioned container can be a regular container or an energy storage container. The following explanation uses an energy storage container as an example. In the bottom structure of some energy storage containers, the top surface of the crossbeam 1 in the third direction Z is higher than the top surface of the bottom plate 2. Fixing the bottom end of the battery bracket 10 to the top surface of the crossbeam 1 allows a gap to be formed between the battery module on the battery bracket 10 and the bottom plate 2 in the third direction Z, effectively preventing contact between the battery module and the liquid water on the bottom plate 2, ensuring the operational safety of the battery module. Under this configuration, if a water guide 4 is arranged in the bottom structure, the presence of the crossbeam 1 will inevitably affect the continuous arrangement of the drainage channels 100 on the water guide 4, thus affecting the effectiveness of the water guide 4.

[0033] In this embodiment, as Figure 1 , Figure 2 , Figure 3As shown, the top surface of the crossbeam 1 along the third direction Z is higher than the top surface of the base plate 2. Multiple crossbeams 1 are spaced apart along the first direction X. A base plate 2 is provided between two adjacent crossbeams 1. The base plate 2 is fixed to the two crossbeams 1. The crossbeam 1 has two ends in the second direction Y. A groove 3 can be opened on one end for the water guide 4 to pass through, or grooves 3 can be opened on both ends respectively. The two grooves 3 are used for the two water guides 4 to pass through respectively.

[0034] In this way, by creating grooves 3 at the ends of each crossbeam 1 and allowing the water guide 4 to pass through multiple grooves 3 sequentially, the crossbeam 1 is prevented from obstructing the drainage channel 7. This creates an uninterrupted drainage channel 100 in the first direction X, facilitating the drainage of liquid water from inside the container. Furthermore, by installing the water guide 4 in the bottom structure, compared to creating drainage holes on each bottom plate 2 individually, the installation of the water guide 4 not only enables centralized drainage of multiple bottom plates 2 but also reduces the number of openings on the bottom plates 2, thereby maintaining the structural strength of the bottom plates 2 and improving their load-bearing capacity.

[0035] Preferably, each crossbeam 1 has a groove 3 at one end along the second direction Y. In this way, a water guide 4 is provided in the bottom structure of the container, and the water guide 4 is located on one side of the bottom structure. This facilitates the drainage of liquid water inside the container, reduces the number of water guides 4, reduces the processing difficulty of the crossbeam 1, and facilitates the production and preparation of the bottom structure.

[0036] In one embodiment, the end of the base plate 2 along the second direction Y is sealed to the water guide 4; the water guide 4 and the side of the groove 3 along the second direction Y are sealed together.

[0037] In this embodiment, as Figure 4 , Figure 5 As shown, the base plate 2 and the water guide 4 are sealed together, and the side of the groove 3 is sealed to the water guide 4. When liquid water on the base plate 2 enters the drainage trough 100, it is not easy to leak out of the drainage trough 100 through the gap between the base plate 2 and the water guide 4. The liquid water entering the drainage trough 100 flows along a preset flow path under the guidance of the drainage trough 100 and is eventually discharged from the container. Furthermore, the side of the water guide 4 can be removed near the end face of the base plate 2 and the side of the groove 3, reducing the amount of material used in the water guide 4 and lowering production costs.

[0038] Specifically, such as Figure 7 As shown, a groove 3 is formed on the end of the crossbeam 1, so that the crossbeam 1 forms a connected first surface 101 and a second surface 102 on the end with the groove 3. The side wall of the water guide 4 is sealed to the first surface 101 of the crossbeam 1, and the water guide 4 is disposed above the second surface 102 in the third direction Z.

[0039] In one embodiment, multiple crossbeams 1 are provided with side beams 5 on both sides along the second direction Y, and the two ends of the crossbeams 1 are respectively connected to the two side beams 5. The water guide 4 is fitted to the end face of the side beams 5 facing the bottom plate 2.

[0040] In this embodiment, as Figure 4 , Figure 5 As shown, taking the example of each crossbeam 1 having a groove 3 at one end, the two ends of the crossbeam 1 along the second direction Y are fixedly connected to the side walls of the two side beams 5 respectively, and a groove 3 is provided on one end of the crossbeam 1, so that the first surface 101 of the crossbeam 1 is opposite to the side beam 5, and the second surface 102 of the crossbeam 1 is located between the first surface 101 and the side beam 5.

[0041] The water guide 4 passes between the side beam 5 and the first surface 101, and the water guide 4 is fitted to the side beam 5 and connected and fixed to the side beam 5. There is no need to install insulation cotton or other insulation structures in the side beam 5. Even if condensation occurs on the side beam 5 due to the large temperature difference between day and night, the condensation can flow along the side beam 5 into the water guide 4. The water guide 4 facilitates the discharge of the condensate on the side beam 5 from the container.

[0042] In one embodiment, the water guide 4 includes a bottom water guide plate 401 and a side water guide plate 402 connected together. The bottom water guide plate 401 is sealed to the end of the bottom plate 2 along the second direction Y, and the bottom water guide plate 401 is sealed to the side of the groove 3 along the second direction Y. The side water guide plate 402 is connected to the side beam 5.

[0043] In this embodiment, as Figure 4 , Figure 5 As shown, the bottom water guide plate 401 can be sealed to the bottom plate 2 by means of bonding or welding, so that liquid water on the bottom plate 2 can flow along the bottom plate 2 to the bottom water guide plate 401. A side water guide plate 402 is fixed on the bottom water guide plate 401, and the side water guide plate 402 is equivalent to the flange of the bottom water guide plate 401 facing upward in the third direction Z. The side water guide plate 402 is connected and fixed to the side beam 5, which improves the installation strength of the bottom water guide plate 401. On the other hand, the side water guide plate 402, the bottom water guide plate 401, the first surface 101 of the crossbeam 1 and one side of the bottom plate 2 enclose each other, thereby forming a drainage channel 100 extending in the first direction X. After the liquid water in the bottom structure enters the drainage channel 100, it flows along the preset drainage path under the guidance of the drainage channel 100, and finally drains the liquid water out of the container.

[0044] In one embodiment, a skin layer 6 is provided on the top surface of the base plate 2. The skin layer 6 has a first end and a second end opposite to each other along the second direction Y. The first end of the skin layer 6 is close to the water guide 4, and the height of the second end of the skin layer 6 along the third direction Z is higher than the height of the first end of the skin layer 6 along the third direction Z.

[0045] In this embodiment, as Figure 5 As shown, the top surface of the base plate 2 can be kept horizontal. A skin layer 6 is arranged on the top surface of the base plate 2, and the top surface of the skin layer 6 is inclined. The skin layer 6 can guide liquid water to the water guide 4, thereby improving the liquid water discharge efficiency. Furthermore, the setting of the skin layer 6 does not require damaging the structure of the base plate 2. While ensuring effective drainage, it can maintain the structural strength of the base plate 2 and reduce the usage cost of the base plate 2.

[0046] Optionally, the height of the second end of the skin layer 6 in the third direction Z is lower than the height of the top surface of the crossbeam 1 in the third direction Z, so that there is a gap between the skin layer 6 and the battery bracket 10, effectively preventing the liquid water on the skin layer 6 from contacting the battery module on the battery bracket 10.

[0047] In one embodiment, a drainage channel 7 is provided on the base plate 2. The drainage channel 7 is located at one end of the water guide 4 along the first direction X. The outlet of the drainage trough 100 is connected to the inlet of the drainage channel 7. The outlet of the drainage channel 7 extends to the outside of the container.

[0048] In this embodiment, as Figure 6 , Figure 7 As shown, the drainage channel 7 is set at one end of the water guide 4. In addition to draining the liquid water in the drainage tank 100 from the container through the drainage channel 7, the number of drainage channels 7 on the bottom plate 2 can also be reduced, so that the bottom plate 2 can maintain its structural strength.

[0049] Optionally, in addition to being located at one end of the water guide 4 as described above, the drainage channel 7 can also be located in the middle of the water guide 4. The specific location of the drainage channel 7 can be adjusted according to actual needs to meet different usage requirements.

[0050] Optionally, a floor drain is installed in the drainage channel 7 to facilitate the discharge of liquid water in the water guide 4 into the container through the drainage channel 7. At the same time, it can also prevent foreign objects from the outside of the container from entering the container through the drainage channel 7, effectively ensuring the safety and cleanliness of the electrical equipment inside the container.

[0051] In one embodiment, the bottom water guide plate 401 has a first end and a second end opposite to each other along a first direction X. The first end of the bottom water guide plate 401 is close to the drainage channel 7, and the height of the second end of the bottom water guide plate 401 along a third direction Z is higher than the height of the first end of the bottom water guide plate 401 along a third direction Z.

[0052] In this embodiment, the bottom water guide plate 401 is inclined along the first direction X, and the bottom water guide plate 401 is set at a low end near the drainage channel 7, so that the liquid water entering the drainage tank 100 can flow quickly towards the drainage channel 7 under the guidance of the bottom water guide plate 401, thereby facilitating the flow of the liquid water collected by the water guide member 4 to the drainage channel 7, and further improving the drainage efficiency.

[0053] Optionally, the bottom water guide plate 401 is inclined, that is, a pad layer can be laid on the end face of the bottom water guide plate 401 facing the drainage trough 100 so that the top surface of the bottom water guide plate 401 has a certain inclined surface, or the bottom water guide plate 401 can be inclined as a whole.

[0054] In one embodiment, when the bottom water guide plate 401 is tilted as a whole, a pad 8 is provided between the bottom water guide plate 401 and the top surface of the crossbeam 1, and the pad 8 is connected to the bottom water guide plate 401 and the crossbeam 1 respectively.

[0055] In this embodiment, as Figure 8 As shown, the pad 8 is set in the groove 3, that is, the pad 8 is set between the second surface 102 of the crossbeam 1 and the bottom surface of the bottom water guide plate 401. The pad 8 can be fixed with the bottom water guide plate 401 and the second surface 102 of the crossbeam 1. The connection strength between the bottom water guide plate 401 and the crossbeam 1 is further improved by the pad 8.

[0056] One or more pads 8 can be provided. When one pad 8 is provided, it is preferably located below the end of the bottom guide plate 401 away from the drainage channel 7. The pad 8 raises the height of the second end of the bottom guide plate 401, thereby tilting the bottom guide plate 401 as a whole. When multiple pads 8 are provided, they are respectively provided on different crossbeams 1 along the first direction X, and the dimensions of the multiple pads 8 are different in the third direction Z. This ensures that the bottom guide plate 401 is tilted along the first direction X while maintaining support for the bottom guide plate 401.

[0057] In one embodiment, a cavity is provided inside the crossbeam 1, and a sealing member 9 is provided on the groove 3. The sealing member 9 is connected to the crossbeam 1 and is used to prevent the cavity from communicating with the water guide member 4.

[0058] In this embodiment, as Figure 8 , Figure 9As shown, to reduce usage costs, the crossbeam 1 typically has a hollow structure, meaning there is a cavity inside. When a groove 3 is cut into one end of the crossbeam 1, the cavity inside the crossbeam 1 is easily exposed. After the water guide component 4 is installed, the resulting drainage channel 100 may connect with the inner cavity of the crossbeam 1, thus affecting the drainage effect of the water guide component 4. Therefore, after the groove 3 is cut into the crossbeam 1, a sealing component 9 is installed on the groove 3 of the crossbeam 1. The sealing component 9 seals the crossbeam 1, preventing liquid water inside the water guide component 4 from entering the cavity of the crossbeam 1, thereby improving the drainage effect of the water guide component 4.

[0059] Optionally, the closure 9 includes a first plate 901 and a second plate 902 connected to each other. The end face of the first plate 901 facing the drainage channel 100 is flush with the first surface 101, and the end face of the second plate 902 facing the drainage channel 100 is flush with the second surface 102. In this way, the first plate 901 and the second plate 902 are fixed to the crossbeam 1 by welding or bonding, which can effectively prevent liquid water in the water guide 4 from entering the cavity of the crossbeam 1.

[0060] Secondly, this application provides an energy storage container, including the bottom structure of any of the above.

[0061] In this embodiment, the energy storage container has the aforementioned bottom structure. By creating grooves 3 at the ends of each crossbeam 1 and allowing the water guide 4 to pass through multiple grooves 3 sequentially, it facilitates the drainage of liquid water from inside the energy storage container. Furthermore, it reduces the number of openings on the bottom plate 2, maintains the structural strength of the bottom plate 2, and improves its load-bearing capacity.

[0062] In one embodiment, a battery holder 10 is also included, which is disposed on the crossbeam 1.

[0063] In this embodiment, as Figure 1 As shown, by mounting the battery bracket 10 on the crossbeam 1, and since the top surface of the crossbeam 1 is higher than the top surface of the base plate 2, a gap can be formed between the battery module on the battery bracket 10 and the base plate 2, effectively preventing the battery module from coming into contact with the liquid water on the base plate 2 and ensuring the operational safety of the battery module. Furthermore, the crossbeam 1 has high structural strength, preventing the base plate 2 from deforming or being damaged by directly bearing the weight of the battery bracket 10.
