DETAILED DESCRIPTION

[0033] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is described in further detail below with reference to embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0034] like Figure 1-Figure 5 As shown, the door panel assembly with a ventilation and rainproof structure provided in this embodiment includes a cabinet door 10 having a through ventilation hole 20. A plurality of blades 30 are arranged in the ventilation hole 20 at intervals along the height direction. These blades 30 are arranged at an angle to form a shutter structure, which can ensure ventilation while also blocking rainwater to a certain extent.

[0035] The top of the blade 30 extends outward from the cabinet door 10 to form a first bent portion 31, and the bottom of the blade 30 extends downward from the cabinet door 10 to form a second bent portion 32. Specifically, the blade 30 includes a blade body 33 and a first bent portion 31 and a second bent portion 32 provided at the top and bottom ends of the blade body 33.

[0036] Of the two adjacent blades 30, the second bent portion 32 of the upper blade 30 is lower than the first bent portion 31 of the lower blade 30. This design not only forms a staggered structure that can effectively prevent rainwater from falling directly into the inner side of the cabinet door 10, but also forms two guide structures.

[0037] The guide structure formed by the second bent portion 32 can guide rainwater to fall directly downwards instead of flowing into the inner side of the cabinet door 10 along the blade body 33 .

[0038] The guide structure formed by the first bent portion 31 forms a certain angle with the blade body 33, with the angle being directed toward the blade body 33 above it. This not only prevents rainwater that may flow along the surface of the blade body 33 from continuing to flow into the cabinet door 10, but also guides the hot air inside the cabinet door 10 to flow out of the cabinet door 10 along the first bent portion 31 of the lower blade 30, the blade body 33 of the upper blade 30, and the second bent portion 32 at its bottom end.

[0039] Through this structural design, even in continuous heavy rain conditions, the problem of rainwater entering the cabinet door 10 through the blades 30 can be reduced, while ensuring the ventilation and heat dissipation environment inside the cabinet body 80 and ensuring the safe operation of electrical components inside the cabinet body 80.

[0040] In this embodiment, the ventilation holes 20 are rectangular and extend from the front side to the back side of the cabinet door 10. Two ventilation holes 20 are provided, spaced apart in the upper and lower sides of the cabinet door 10. This provides good ventilation and heat dissipation while ensuring rain protection.

[0041] In this embodiment, the top end of the blade 30 extending outward from the cabinet door 10 can mean that the top end of the blade 30 extends horizontally outward, forming an acute angle between the first bent portion 31 and the blade body 33. Furthermore, the right end of the first bent portion 31 points toward the blade body 33 above it, thereby effectively guiding airflow. In other embodiments, the angle between the first bent portion 31 and the blade body 33 can be adjusted as appropriate, as long as the airflow guiding effect is achieved.

[0042] In this embodiment, the bottom end of the blade 30 extending downward from the cabinet door 10 may mean that the bottom end of the blade 30 extends vertically downward, forming a second bent portion 32 that can directly guide rainwater falling thereon to the ground. In other embodiments, the extension direction of the second bent portion 32 can be adjusted as long as it can guide rainwater falling thereon.

[0043] In one embodiment, of two adjacent blades 30 , the bottom surface of the second bent portion 32 of the upper blade 30 and the middle portion of the lower blade are in the same horizontal plane.

[0044] Specifically, the two adjacent blades 30 remain on the same vertical plane, and their basic positional relationship remains unchanged. The second bend 32 of the upper blade 30 extends to the horizontal area in the middle of the lower blade 30, creating a longer rainwater flow path. Furthermore, the two blades 30 form an overlapping area, making it more difficult for rainwater to pass directly through the gap between the two blades 30. This design improves rain protection without changing the basic arrangement of the blades 30.

[0045] In addition, although an overlap is formed between the two blades 30, since the second bend 32 of the upper blade 30 only extends to the horizontal area where the middle part of the lower blade 30 is located, sufficient space is still retained for air circulation, ensuring good ventilation effect, thereby ensuring normal heat dissipation of electrical components in the cabinet body 80 and balancing the rain protection and ventilation requirements of the energy storage cabinet.

[0046] In one embodiment, a filter 40 is disposed inside the plurality of blades 30 .

[0047] The setting of the filter 40 does not substantially affect the ventilation effect of the cabinet door 10, and can prevent debris such as leaves from entering the interior of the cabinet body 80. The filter 40 can be made of a metal mesh with good air permeability.

[0048] In this embodiment, a support member 50 is provided inside the cabinet door 10. The support member 50 is provided below the ventilation hole 20 and includes a fixing portion 51 and a supporting portion 52 fixedly connected to each other. The fixing portion 51 is located between the cabinet door 10 and the supporting portion 52.

[0049] The fixing portion 51 is connected to the inner side of the cabinet door 10 , and the filter screen 40 is vertically fixed to the top surface of the supporting portion 52 .

[0050] In this embodiment, Figure 5 As shown, the fixing portion 51 is L-shaped, and a liquid collecting tank 60 with closed ends is formed between the fixing portion 51 and the cabinet door 10. The supporting portion 52 is a plate-like structure, which is inclined upward relative to the fixing portion 51. Here, the upward inclination refers to that the supporting portion 52 is inclined upward relative to the horizontal plane.

[0051] The support portion 52 is located directly below the top of the blade 30 . The support portion 52 can guide rainwater falling from the top of the blade 30 to slide into the sump 60 .

[0052] A drainage hole 70 is provided on the inner side of the cabinet door 10 and is communicated with the liquid collecting tank 60. The purpose of this design is to provide a drainage channel for the collected water and prevent the water from accumulating in the liquid collecting tank 60.

[0053] With the above improvements, even if a small amount of rainwater seeps in, it can be collected by the sump 60 and discharged through the drainage holes 70, instead of directly falling into the cabinet 80 and accumulating.

[0054] In another embodiment, the sump 60 is located directly below the top of the blade 30 and can directly collect rainwater that may penetrate from the blade 30 .

[0055] In the above embodiment, the bottom surface of the drain hole 70 is lower than the bottom surface of the sump 60 to ensure that the water in the sump 60 can be completely drained without any residual water. This improves the drainage effect and prevents long-term accumulation of water in the sump 60.

[0056] In one embodiment, an integrated energy storage cabinet is provided, comprising a cabinet body 80, the front of which is hingedly provided with the aforementioned door panel assembly with a ventilated and rainproof structure. The hinged installation of the door panel assembly with a ventilated and rainproof structure on the front of the cabinet body 80 enhances the rainproof capability of the entire integrated energy storage cabinet. This design effectively prevents rainwater from seeping into the interior of the cabinet body 80 through the cabinet door 10, particularly during periods of sustained heavy rain.

[0057] Improved rainproof performance directly reduces the potential damage of rainwater to electrical components inside the cabinet 80, such as the battery box 92, energy storage converter 91, and other core components. This greatly improves the safety and reliability of the energy storage cabinet in adverse weather conditions.

[0058] In one embodiment, a battery rack assembly 90 is provided within the cabinet 80. Within the battery rack assembly 90, adjacently arranged energy storage and conversion devices 91 and multiple battery boxes 92 are provided. A distribution box 93 and a high-voltage box 94 are provided at the bottom of the multiple battery boxes 92. The battery boxes 92 are connected to the energy storage and conversion devices 91, the distribution box 93, and the high-voltage box 94, respectively.

[0059] The energy storage and conversion device 91 includes a power converter (PCS) and related accessories, such as a UPS, wirewound resistors, and transformers (not shown). The distribution box 93 distributes electrical energy and provides power-off protection against overloads, short circuits, and leakages. The high-voltage box 94 collects voltage and current data from the battery box 92 and communicates with the battery management system (not shown) and the PCS.

[0060] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present invention within the scope disclosed by the present invention, which falls within the protection scope of the present invention.
