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

[0029] The following is combined with Figures 1 to 6 The following describes embodiments of the present invention.

[0030] According to an embodiment of this utility model, an energy storage cabinet is provided, comprising: a cabinet body 1, a partition 2, a sealing plate 7, a cabinet door 8, a battery pack 5, electrical components 6, and a pipeline structure 9. The cabinet body 1 forms an internal accommodating space, and one side of the cabinet body 1 has an opening communicating with the accommodating space. The partition 2 is disposed within the cabinet body 1 to divide the accommodating space into a battery compartment 3 and an electrical compartment 4, with the opening corresponding to the portion of the battery compartment 3 forming a hatch. The battery pack 5 is disposed within the battery compartment 3, and the electrical components 6 are disposed within the electrical compartment 4. The sealing plate 7 is connected to the side of the cabinet body 1 with the opening and to the partition 2, and covers the hatch; the cabinet door 8 is connected to the cabinet body 1 and covers the opening. The pipeline structure 9 connects the battery pack 5 and the electrical components 6 and passes through the partition 2, with the pipeline structure 9 and the partition 2 sealed together.

[0031] The cabinet body 1 is sealed by setting the cabinet door 8, and the battery compartment 3 is further sealed by setting the sealing plate 7. At the same time, the position where the pipeline structure 9 passes through the partition 2 is sealed. Even when the cabinet door 8 is opened, the sealing performance of the battery compartment 3 can still be maintained, preventing external moisture from entering the battery compartment 3, thereby preventing condensation problems in the battery compartment 3 and ensuring the safety of the battery pack 5 operation.

[0032] It should be noted that the battery pack 5 is the main component of the energy storage system, and the pipeline structure 9 is mainly used for controlling the temperature and power transmission of the battery pack 5 as well as system communication control.

[0033] It is worth noting that, please refer to Figures 1 to 4 The cabinet 1 has a square box structure with an opening on one side. Specifically, the cabinet 1 has a five-panel structure with an opening on one side. The front side of the cabinet 1 is open, while the rear, left, right, top, and bottom sides are all panels. The cabinet door 8 and the sealing plate 7 are both connected to the front of the cabinet 1. Furthermore, the sealing plate 7 is located on the side of the cabinet door 8 closest to the opening. The coverage area of ​​the sealing plate 7 is smaller than that of the cabinet door 8; that is, the cabinet door 8 covers the entire opening, while the sealing plate 7 covers the hatch of the battery compartment 3.

[0034] It should be noted that in related technologies, two independently set door panels are used to seal the battery compartment 3 and the electrical compartment 4 respectively. Although this allows the battery compartment 3 and the electrical compartment 4 to be opened separately, it results in poor overall integrity and aesthetics of the energy storage cabinet.

[0035] In this embodiment, a complete cabinet door 8 is used to cover the opening of the cabinet 1, ensuring the integrity and aesthetics of the overall structure of the energy storage cabinet. Furthermore, a sealing plate 7 is used to separately cover and seal the hatch of the battery compartment 3. When the cabinet door 8 is opened (for example, when the electrical compartment 4 needs maintenance), external moisture will not enter the battery compartment 3. In addition, since the pipeline structure 9 is also sealed at the point where it penetrates the partition 2, moisture in the electrical compartment 4 will not enter the battery compartment 3, further avoiding the condensation problem in the battery compartment 3.

[0036] In one embodiment, such as Figure 6 As shown, the partition 2 has a perforation, and a sealing joint 10 is installed at the perforation. The pipeline structure 9 is connected to the sealing joint 10. That is, the sealing joint 10 is used to achieve a seal between the partition 2 and the pipeline structure 9.

[0037] Specifically, the pipeline structure 9 includes conduits and / or cables, which are installed at the perforation via wall-penetrating joints and waterproof joints to allow the conduits and cables to pass through the partition 2. Furthermore, the wall-penetrating joints and waterproof joints are fixed to the perforation via fine-pitch threads and tightened to both sides of the partition 2. Sealing rings can also be installed between the wall-penetrating joints and waterproof joints and the partition 2 to further enhance the sealing effect of the pipeline structure 9 at the point of penetration into the partition 2.

[0038] As an alternative implementation, the partition 2 has a perforation, the pipeline structure 9 passes through the perforation, and a first sealing structure fills the space between the perforation and the outer wall of the pipeline structure 9. Specifically, the first sealing structure can be sealing cotton, sealing mud, or sealing adhesive, etc.

[0039] In one embodiment, such as Figure 5 As shown, the cabinet 1 has a first mounting surface 101 formed around the opening on one side, and a second mounting surface 102 formed around the hatch on the same side. The first mounting surface 101 surrounds the outer periphery of the second mounting surface 102. The cabinet door 8 facing the opening is opposite to the first mounting surface 101, and the sealing plate 7 facing the battery compartment 3 is opposite to the second mounting surface 102. Specifically, the first mounting surface 101 and the second mounting surface 102 are coplanar; or, the first mounting surface 101 and the second mounting surface 102 are stepped, meaning the first mounting surface 101 is further away from the receiving space than the second mounting surface 102.

[0040] It is worth noting that the sealing plate 7 is positioned opposite the second mounting surface 102 and the side of the partition plate 2 facing the opening.

[0041] In one embodiment, such as Figure 5As shown, the energy storage cabinet also includes a second sealing structure 11, which is disposed between the cabinet body 1 and the side of the partition 2 and the sealing plate 7 facing the hatch. By providing the second sealing structure 11 between the sealing plate 7 and the cabinet body 1, and between the sealing plate 7 and the partition 2, the sealing effect of the sealing plate 7 on the battery compartment 3 is enhanced.

[0042] Specifically, in this embodiment, the second sealing structure 11 is a sealing strip.

[0043] Of course, in other alternative embodiments, the second sealing structure 11 can also be other components that can perform a sealing function, such as sealing cotton.

[0044] In one embodiment, the energy storage cabinet further includes fasteners that penetrate the sealing plate 7 and are secured to the cabinet body 1 and the partition 2. Using fasteners to connect the sealing plate 7 to the cabinet body 1 and the partition 2 facilitates the installation and removal of the sealing plate 7, thereby enabling convenient inspection and maintenance of the battery compartment 3.

[0045] Specifically, in this embodiment, the fasteners are bolts, and several fasteners are spaced apart along the circumferential edge of the sealing plate 7. The sealing plate 7 is installed using the fasteners, and under the tightening action of the fasteners, the sealing plate 7 compresses the sealing strip, thereby enabling the sealing strip to perform a sealing function.

[0046] Of course, in other alternative implementations, other connection methods can be used to connect the sealing plate 7 to the cabinet 1 and the partition 2, such as setting a slot on the cabinet 1 so that the outer periphery of the sealing plate 7 is inserted into the slot.

[0047] In one embodiment, such as Figure 6 As shown, the energy storage cabinet also includes a heat insulation structure 12, which is disposed on the side of the partition 2 facing the electrical compartment 4 and / or the side of the partition 2 facing the battery compartment 3. By providing the heat insulation structure 12 on the partition 2, the mutual influence of heat inside the battery compartment 3 and the electrical compartment 4 is reduced, thus avoiding any impact on the operation of the battery pack 5 and electrical components 6.

[0048] Specifically, in this embodiment, the heat insulation structure 12 is thermal insulation cotton.

[0049] In one embodiment, such as Figures 1 to 4 As shown, the energy storage cabinet also includes a base 13, which is located at the lower end of the cabinet body 1.

[0050] In one embodiment, at least a portion of the sealing plate 7 is a transparent structure. Specifically, the entire sealing plate 7 can be a transparent structure, such as an acrylic sheet; or, the sealing plate 7 can be a sheet metal plate with an observation opening, and a transparent structure (transparent plate, transparent film, etc.) can be connected to the sealing plate 7 and cover the observation opening.

[0051] By setting a transparent structure, the interior of the battery compartment 3 can be easily observed through the sealing plate 7, thereby observing the operation of components such as the battery pack 5 inside the battery compartment 3 and the condensation inside the battery compartment 3, making it easier for staff to understand the internal conditions of the battery compartment 3.

[0052] In one embodiment, such as Figure 3 and Figure 4 As shown, the partition 2 extends horizontally so that the battery compartment 3 and the electrical compartment 4 are arranged vertically. Specifically, the battery compartment 3 and the electrical compartment 4 are arranged vertically, with the battery compartment 3 located above the electrical compartment 4.

[0053] As an alternative implementation, the partition 2 extends vertically so that the battery compartment 3 and the electrical compartment 4 are arranged horizontally. That is, the battery compartment 3 and the electrical compartment 4 are arranged in the left-right direction.

[0054] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
