Description

Technical Field

[0001] This application relates to the field of energy storage system technology, and in particular to a battery cluster storage rack suitable for energy storage systems. Background Technology

[0002] Electric energy storage systems are developing towards higher voltage, larger capacity, clustering, and large scale, and are widely used in industrial park electricity sales, large charging stations, and photovoltaic power generation industries. They integrate several structures such as cooling systems, battery modules, and fire protection systems, thus placing higher demands on the capacity and lifespan of energy storage systems.

[0003] Battery clusters are typically composed of several battery modules stacked and connected in series. To improve the assembly reliability of battery clusters, these modules are usually placed on a dedicated storage rack, which is equipped with a pull-out mechanism for quick assembly and disassembly of the battery modules. In existing technologies, fans are also installed on the storage rack to cool the battery modules.

[0004] However, when using air cooling, the external air flows directly inside the storage rack, which can easily cause dust accumulation and adversely affect the working environment of the battery module. Although some storage racks are equipped with filters, cleaning and replacing the filters is cumbersome and increases the maintenance difficulty of the storage rack. Utility Model Content

[0022] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0023] A battery cluster storage rack suitable for energy storage systems includes a frame body 1. The frame body 1 has several partitions 2 arranged at intervals along the height direction of the frame body 1. Placement areas 3 are formed between adjacent partitions 2 and between partitions 2 and the frame body 1. Placement areas 3 are used to place battery modules. Battery modules in different placement areas 3 can be connected to each other. A panel 4 is provided on the front side of the frame body 1, which covers the front end face of the frame body 1. A mesh plate 5 is provided on the rear side of the frame body 1, which covers the rear end face of the frame body 1. A fan 6 is provided on the partition 2 and near the mesh plate 5, and the fan 6 blows air towards the panel 4. A filter assembly 7 is detachably provided on the outside of the mesh plate 5, which is used to filter the air entering the frame body 1.

[0024] When battery modules are placed in each placement area 3 and connected, a usable battery cluster is formed. When the battery cluster starts supplying power, the fan 6 also rotates simultaneously, creating an air duct that enters from the rear of the frame 1 and exits from the front, effectively dissipating heat from the frame 1. The mesh plate 5 and the detachable filter assembly 7 on the mesh plate 5 provide dual filtration of the air entering the frame 1, effectively preventing dust and other debris from entering and providing a good working environment for the battery cluster. After a period of use, the filter assembly 7 can be removed from the mesh plate 5 and a new filter assembly 7 installed, ensuring continuous and reliable air filtration. This simple operation reduces the maintenance difficulty of the frame 1.

[0025] The partition 2 is detachably connected to the inner wall of the frame 1, and the panel 4 is hinged to the front end face of the frame 1. The installation position of the partition 2 inside the frame 1 is not fixed, so the distance between the two partitions 2 can be flexibly adjusted, thereby reliably adjusting the size of the placement area 3. The panel 4 is hinged to the bracket of the frame 1, facilitating the opening and closing of the panel 4.

[0026] The filter assembly 7 includes a housing 71 and a cover 72. The housing 71 is open on the side facing away from the mesh plate 5, and the cover 72 is screwed onto the open side of the housing 71. Both the cover 72 and the housing 71 are made of perforated plates, and their filtration accuracy is lower than that of the mesh plate 5. When the fan 6 starts running, external air first enters the housing 71 through the cover 72 or directly into the housing 71, and then passes through the mesh plate 5. In this way, through multiple filtrations of different filtration accuracies, the amount of dust entering the frame 1 is minimized, thereby reliably protecting the battery cluster. Furthermore, after the filter assembly 7 has been used for a period of time, it can be removed from the mesh plate 5, and the inside of the cover 72 and the housing 71 can be easily cleaned by opening the cover 72.

[0027] Two L-shaped clips 50 are symmetrically arranged on the outer side of the mesh plate 5. The vertical end of the clip 50 is connected to the mesh plate 5, and the horizontal end of the clip 50 is parallel to the mesh plate 5. Two clips 710 are symmetrically arranged on the side of the housing 71 facing the mesh plate 5. The two clips 710 are respectively and correspondingly locked between the horizontal end of the clip 50 and the outer wall of the mesh plate 5. In this way, the detachable connection between the housing 71 and the mesh plate 5 is reliably realized.

[0028] A first sleeve 721 is provided in the middle of the inner wall of the cover 72. A first spring 722 and a second sleeve 723 are provided inside the first sleeve 721. The outer wall of the second sleeve 723 is in contact with the inner wall of the first sleeve 721. A second spring 724 and a movable plate 725 are provided inside the second sleeve 723. A hemispherical base 726 is provided on the side of the movable plate 725 facing away from the second spring 724. Several bristles 727 are inserted into the base 726, and each bristle 727 is perpendicular to the outer surface of the base 726. When the cover 72 is screwed onto the outside of the housing 71, the first spring 722 and the second spring 724 are both in a compressed state, and the second sleeve 723 moves to the inside of the first sleeve 721, and the bristles 727 move to the inside of the second sleeve 723, ensuring that air can flow smoothly inside the housing 71. When the housing 71 needs to be cleaned, rotate the cover 72 to separate it from the housing 71. At this time, under the action of the first spring 722 and the second spring 724, the second sleeve 723 will move towards the outside of the first sleeve 721, and the bristles 727 will move towards the outside of the second sleeve 723. This increases the overall length of the first sleeve 721 and the second sleeve 723. At the same time, the second sleeve 723 makes contact with the limiting action of the bristles 727, and the bristles 727 can change from a gathered state to a dispersed state, thereby increasing the overall outer diameter of the bristles 727. Then, by rotating the cover 72, the bristles 727 can be rotated inside the housing 71, thereby achieving the brushing of the housing 71. The housing 71 can be quickly cleaned without the use of other tools, further improving maintenance efficiency.

[0029] One end of the first spring 722 is connected to the inner side of the bottom of the first sleeve 721, and the other end of the first spring 722 is connected to the outer side of the bottom of the second sleeve 723. One end of the second spring 724 is connected to the inner side of the bottom of the second sleeve 723, and the other end of the second spring 724 is connected to the movable plate 725. In this way, the first sleeve 721, the first spring 722, the second sleeve 723, the second spring 724 and the movable plate 725 can form a telescopic whole.

[0030] The length of the bristles 727 is greater than the inner diameter of the second sleeve 723. The second sleeve 723 also contains an elastic pull cord 728. One end of the pull cord 728 is connected to the movable plate 725, and the other end extends axially along the second sleeve 723 to the outside of the cover 72. The other end of the pull cord 728 has a pull ring 729. By pulling the pull ring 729 and the pull cord 728, the movable plate 725 is reset, ensuring that the bristles 727 can retract back into the inner side of the second sleeve 723 before the cover 72 is screwed back onto the housing 71.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
