Description

Technical Field

[0001] The utility model relates to the technical field of energy storage cabinets, and more specifically, to a series-connected energy storage integrated cabinet. Background Technique

[0002] An energy storage integrated cabinet is a device used in an energy storage system, which usually includes key components such as a battery pack, an inverter, and a control system. The design of the energy storage cabinet aims to integrate these key components into a cabinet structure for easy installation, maintenance, and management. Energy storage cabinets are widely used in various fields, including home energy storage, commercial and industrial applications, and power grid dispatching. By effectively storing and releasing electrical energy, energy storage cabinets can help balance the power system, improve energy utilization efficiency, and support the integration and utilization of renewable energy sources, such as wind power or solar power generation.

[0003] The patent with the Chinese patent publication number CN220086767U discloses a distributed energy storage cabinet. By adopting a combination of liquid cooling and air cooling, the heat dissipation effect of the battery module is improved. While the air cooling dissipates heat inside the energy storage cabinet, it also dissipates heat from the liquid cooling system, improving the overall heat dissipation effect. After the power distribution unit and the control box are placed inside the energy storage cabinet, it will not cause overheating of the battery module. Moreover, the PCS module and the power distribution unit are arranged front and back, improving the space utilization rate. When the cabinet body of the same capacity has the same external dimensions and does not affect the heat dissipation of the battery module, the power distribution unit and the control box are arranged inside the energy storage cabinet.

[0004] However, the storage capacity and the load for processing electrical energy of a single energy storage cabinet are limited. Therefore, when used in some places with large energy storage requirements, multiple energy storage cabinets need to be connected in series. At the same time, when multiple energy storage cabinets are connected in series, if one cabinet fails, the other cabinets can still continue to operate, which can improve the reliability of the system. When the energy storage cabinets are connected in series, cables are required to connect them together. However, in the above-mentioned energy storage cabinets, the cables are exposed when connected in series. The exposed cables are easily affected by the external environment, increasing the risk of electrical safety accidents.

[0035] Based on this, it is possible to improve the problem in the related technology that when the energy storage cabinet is strung, the cables are exposed outside, and the exposed cables are easily affected by the external environment, increasing the risk of electrical safety accidents.

[0036] Please refer to Figures 1-6 , a series-connected energy storage integrated cabinet, including a cabinet body 1 and a plurality of fixing components 6. Side cabinet plates 3 are detachably installed on both sides of the cabinet body 1. A connecting component 4 is arranged on one side of the cabinet body 1, and an installation component 5 is arranged on the side of the cabinet body 1 away from the connecting component 4. A control system 8, an inverter component 9 and an energy storage module 10 are respectively arranged inside the cabinet body 1. A plurality of movable doors 2 are rotatably connected to the outer end of the cabinet body 1. The connecting component 4 includes a main frame body 41, the main frame body 41 is fixedly installed on the outer side of the cabinet body 1, and a plurality of connecting blocks 42 are fixedly connected to both sides of the main frame body 41 at equal intervals.

[0037] The device in this solution is mainly used for energy storage equipment. By effectively storing and releasing electrical energy, the energy storage cabinet can help balance the power system and improve energy utilization efficiency. Inside the cabinet body 1, a control system 8, an inverter module 9, and an energy storage module 10 are respectively arranged. Among them, the control system 8 is the brain of the energy storage system, responsible for monitoring, regulating, and managing the operating status and performance of the entire energy storage system, and realizing functions such as charge and discharge control, power management, fault diagnosis, data acquisition and analysis. It is usually composed of components such as a main controller, sensors, actuators, and communication modules. The inverter module 9 is a key component in the energy storage system, used to convert the stored DC electrical energy into AC electrical energy for supplying to the power grid or other AC loads. By controlling the on and off of switching devices such as thyristors and transistors, the voltage and frequency are regulated to convert DC into AC that meets the requirements. The energy storage module 10 is the basic component unit of the energy storage system, usually composed of lithium batteries.

[0038] At the outer end of the cabinet body 1, three movable doors 2 are rotatably connected. Inside the cabinet body 1, the interior is divided into three parts by a rack for respectively installing the control system 8, the inverter module 9, and the energy storage module 10. The three spaces can be respectively opened through the three movable doors 2. The side cabinet plates 3 installed on both sides of the cabinet body 1 are detachable and can be connected by bolts or buckles. When multiple cabinet bodies 1 need to be connected in series, the side cabinet plates 3 can be removed to facilitate the internal communication of multiple cabinet bodies 1. On both sides of the cabinet body 1, a connection component 4 and an installation component 5 are respectively arranged. When multiple energy storage cabinets are assembled, the main frame 41 can be inserted into the sub-frame 51, and then the fixing component 6 is used to connect the connection block one 42 and the connection block two 54.

At the same time, through the connection of the main frame 41 and the sub-frame 51, multiple energy storage cabinets can be neatly and evenly arranged when connected in series, improving the aesthetics.

[0039] Optionally, in some embodiments, please refer to Figures 3-5 , a friction strip 43 is fixedly connected to the outer end of the main frame 41, and the outer end of the main frame 41 extends into the interior of the sub-frame 51.

On both sides of the outer end of the main frame 41, a plurality of first connecting blocks 42 are respectively and fixedly installed. On both sides of the outer end of the auxiliary frame 51, a plurality of second connecting blocks 54 are fixedly installed. The positions of the second connecting blocks 54 and the first connecting blocks 42 correspond one by one. At the same time, on both sides of the outer end of the auxiliary frame 51, heat dissipation grooves 52 are also opened. The heat dissipation grooves 52 are mainly used for heat dissipation. On the other side of the heat dissipation grooves 52, that is, inside the auxiliary frame 51, a plurality of heat dissipation fans 7 are installed. The heat dissipation fans 7 are mainly used to cooperate with the heat dissipation grooves 52 to discharge the hot air inside and suck in the cold air outside, achieving the effect of heat dissipation. At the same time, a filter screen needs to be provided in the heat dissipation grooves 52 to prevent external dust from entering.

[0042] A friction strip 43 is fixed on the outer end of the main frame 41. The friction strip 43 is made of rubber material. An abutting block 53 is fixed inside the auxiliary frame 51. The abutting block 53 is arranged in an L shape. When the main frame 41 extends into the interior of the auxiliary frame 51, the friction strip 43 on the main frame 41 will be inserted into the abutting block 53. The frictional force generated by the friction strip 43 and the abutting block 53 can improve the connection strength. At the same time, since the friction strip 43 is made of rubber material, it can also play a buffering role to prevent damage caused by the shaking of the main frame 41 and the auxiliary frame 51.

[0043] Optionally, in some embodiments, please refer to Figures 3-6 , the fixing assembly 6 includes a main shaft 61. A plurality of limiting blocks 67 distributed at equal intervals in a ring shape are fixedly connected to the bottom end of the main shaft 61. Limiting holes adapted to the limiting blocks 67 are opened at the outer ends of the first connecting blocks 42 and the second connecting blocks 54.

[0044] The main shaft 61 respectively penetrates through the first connecting blocks 42 and the second connecting blocks 54, and the outer end of the limiting block 67 abuts against the second connecting block 54.

[0045] Activity rings 64 and gaskets 63 are respectively sleeved on the outer end of the main shaft 61. A plurality of sliders 65 are fixedly connected to the inner side of the activity ring 64. A plurality of chutes 66 adapted to the sliders 65 are opened at the outer end of the main shaft 61. The sliders 65 are slidably connected to the chutes 66.

[0046] A telescopic spring 68 is sleeved on the outer end of the main shaft 61. The telescopic spring 68 is located between the activity ring 64 and the gasket 63. A pressing handle 62 is fixedly connected to the top end of the main shaft 61. The outer end of the activity ring 64 abuts against the first connecting block 42.

[0047] The fixed component 6 in this solution is mainly used to quickly fix the connection component 4 and the installation component 5. A gasket 63, a telescopic spring 68, and a movable ring 64 are sleeved on the outer end of the main shaft 61 respectively. The telescopic spring 68 is located between the gasket 63 and the movable ring 64. The gasket 63 is mainly used to cooperate with the movable ring 64 to squeeze the telescopic spring 68. Three sliders 65 are fixed on the inner side of the movable ring 64, and three sliding grooves 66 are opened on the outer end of the main shaft 61. The movable ring 64 is slidably connected to the main shaft 61 through the sliders 65 in the sliding grooves 66 on the main shaft 61. Four limiting blocks 67 are fixed at the bottom of the main shaft 61, and a pressing handle 62 is fixed at the top. When the main frame 41 extends into the inner side of the sub-frame 51, the first connecting block 42 and the second connecting block 54 will be aligned, and at the same time, the limiting holes on the first connecting block 42 and the second connecting block 54 will also be aligned. At this time, only the limiting block 67 needs to be aligned with the limiting hole and inserted. At this time, the movable ring 64 will squeeze the telescopic spring 68, and then rotate the main shaft 61 through the pressing handle 62 to make the limiting hole on the limiting block 67 and the second connecting block 54 misaligned. Through the acting force of the telescopic spring 68, the limiting block 67 and the movable ring 64 can clamp the first connecting block 42 and the second connecting block 54, and rapid connection can be completed, thereby improving the installation convenience and completing the installation without using other tools.

[0048] Working principle: When using this device to connect multiple groups in series, first, the side cabinet boards 3 on both sides of the cabinet body 1 need to be disassembled, and then the main frame 41 is extended into the interior of the sub-frame 51. A friction strip 43 made of rubber material is fixed on the outer end of the main frame 41, and an abutting block 53 is fixed inside the sub-frame 51. The friction strip 43 on the main frame 41 will be inserted into the abutting block 53, which can play a buffering role. Then the first connecting block 42 and the second connecting block 54 will be aligned, and at the same time, the limiting holes on the first connecting block 42 and the second connecting block 54 will also be aligned. At this time, only the limiting block 67 needs to be aligned with the limiting hole and inserted. At this time, the movable ring 64 will squeeze the telescopic spring 68, and then rotate the main shaft 61 through the pressing handle 62 to make the limiting hole on the limiting block 67 and the second connecting block 54 misaligned. Through the acting force of the telescopic spring 68, the limiting block 67 and the movable ring 64 can clamp the first connecting block 42 and the second connecting block 54 to complete rapid connection.
