Description

Technical Field

[0001] This utility model relates to the field of electrochemical energy storage technology, specifically to a drainage structure for an energy storage battery cabinet. Background Technology

[0002] Due to high humidity and moisture content in the air, or the temperature difference between the inside and outside of the energy storage battery cabinet, hot and humid air from outside the cabinet enters and easily forms condensation when it encounters the cooler outer surface of the battery pack (or electrical components). To prevent condensation from accumulating inside the energy storage battery cabinet and to ensure its rapid drainage, there is an urgent need for a drainage structure for the energy storage battery cabinet that can quickly collect and drain condensation, ensure that the battery pack is in a relatively dry environment, and is easy to maintain and inspect. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a drainage structure for energy storage battery cabinets, which can quickly collect and discharge condensate, ensure that the battery pack is in a relatively dry environment, and facilitate maintenance and inspection of drainage.

[0004] The technical solution adopted by this utility model is as follows: a drainage structure for an energy storage battery cabinet, including a first partition, the first partition being connected to a battery cluster frame for supporting battery packs and electrical components, the first partition, the battery cluster frame and the cabinet body of the energy storage battery cabinet cooperating to divide the interior of the cabinet into a first space for placing multiple battery packs and a second space for placing multiple electrical components, the first space being located above the second space;

[0005] The orthographic projection of the battery pack is located inside the outer edge of the first separator. The end of the first separator near the rear end of the battery pack is located above the end of the first separator near the front end of the battery pack. The end of the first separator near the front end of the battery pack is provided with a drain hole. The drain hole is located outside the orthographic projection of the front end of the battery pack and the orthographic projection of the front end of the electrical components. The drain hole is connected to a drain pipe that communicates with the outside.

[0006] Explanation: The energy storage battery cabinet includes a cabinet body and a battery cluster rack, with the battery cluster rack located inside the cabinet body.

[0007] The principle of the technical solution:

[0008] The first space is located above the second space, meaning multiple battery packs are located above multiple electrical components. Since the orthographic projection of the battery packs is located inside the outer edge of the first partition, condensation from the outer surfaces of the multiple battery packs drips onto the first partition. Because the end of the first partition near the rear end of the battery pack is above the end near the front end of the battery pack (i.e., the end near the rear end of the first partition is higher, and the end near the front end is lower), the condensation dripping onto the first partition converges towards the drain hole. The drain hole is located outside the orthographic projection of the front end of the battery pack, ensuring that the collected condensation is away from the battery pack, thus ensuring that no condensation accumulates under the battery packs near the first partition, thereby ensuring that the battery packs are in a relatively dry environment. The drain hole is also located outside the orthographic projection of the front end of the electrical components, ensuring that the condensation dripping from the drain hole is also away from the electrical components. The accumulated condensation is discharged from the cabinet through the drain pipe.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] The battery pack of this invention has its orthographic projection located inside the outer edge of the first separator, allowing the first separator to receive condensate dripping from multiple battery packs, preventing condensate from dripping onto other circuits and causing short circuits. The end of the first separator near the rear end of the battery pack is positioned above the end near the front end, allowing for convenient and rapid collection of condensate. The drain hole is located outside the orthographic projection of the front end of the battery pack, keeping condensate away from the battery pack and ensuring that the battery pack near the first separator is in prolonged contact with the accumulated condensate, maintaining a relatively dry environment. This prevents oxidation of the metal electrode surfaces inside the battery pack near the first separator, which could lead to corrosion and internal short circuits. It also prevents a reduction in battery charging and discharging performance and a shortened battery life. The drain hole is located outside the orthographic projection of the front end of the electrical components, ensuring that the condensate flowing out of the drain hole stays away from the electrical components, preventing moisture damage to the electrical components and protecting the equipment from humid environments. The drain hole and drain pipe work together to quickly drain accumulated condensate from the cabinet.

[0011] In a preferred embodiment of this utility model, the first separator includes a first collecting part and a second collecting part, which are spliced ​​together. Both the first collecting part and the second collecting part are connected to the battery cluster frame. The middle part of the upper surface of the second collecting part is recessed along the width direction of the battery pack. The width of the recessed part of the second collecting part is greater than the width of the battery pack. The upper surface of the recessed part of the second collecting part is located below the upper surface of the first collecting part. The drainage hole is located in the recessed part of the second collecting part. The recessed parts of the second collecting part are all located outside the orthographic projection of the battery pack and the orthographic projection of the electrical components.

[0012] Beneficial effects: The middle of the upper surface of the second collection part is recessed along the width of the battery pack. The width of the recess of the second collection part is greater than the width of the battery pack. The upper surface of the recess of the second collection part is located below the upper surface of the first collection part. The drain hole is located in the recess of the second collection part, which ensures that the condensate on the outer surface of the battery pack can drip onto the first collection part and accumulate in the second collection part through the first collection part, and then be discharged through the drain hole.

[0013] In a preferred embodiment of the present invention, both the first collecting part and the second collecting part are hollow boxes, and the interior of the first collecting part and the second collecting part are provided with heat insulation cotton.

[0014] Beneficial effects: The hollow enclosure can increase the strength of the first partition and also accommodate heat insulation cotton. The heat insulation cotton can keep the temperature warm and reduce heat exchange between the first and second spaces, thereby ensuring rapid heat dissipation of multiple battery packs during charging and discharging.

[0015] In a preferred embodiment of the present invention, the lower surface of the second collecting part is provided with a plurality of limiting members for limiting the wire harness, which are arranged along the length direction of the second collecting part. The limiting members are located outside the orthographic projection of the electrical component.

[0016] Beneficial effects: The second collection section can also be used to set a limiting member, thereby binding the wire harness connected to the electrical components, and the limiting member can also improve the strength of the second collection section.

[0017] In a preferred embodiment of the present invention, the limiting member includes a limiting strip and a plurality of limiting rings spaced apart on the limiting strip along the length direction of the limiting strip.

[0018] Beneficial effect: The limiting strip provides support for the limiting ring, which facilitates the passage of the wire harness, thereby limiting the wire harness.

[0019] As a preferred embodiment of the present invention, it also includes a second partition located at the bottom of the cabinet body. The second partition is connected to the battery cluster rack, and multiple electrical components are located above the second partition. The second partition is used to separate the inside of the cabinet body from the outside.

[0020] The second separator is provided with multiple drainage sections, each drainage section including multiple rows and columns of through holes, and each drainage section is provided with dustproof cotton.

[0021] Beneficial effects: Condensation on electrical components can be drained from the cabinet in a timely manner through the drain section on the second partition, and the dustproof cotton can prevent dust from entering the cabinet. Attached Figure Description
