Technical Field

[0001] The utility model belongs to the technical field of energy storage batteries, and in particular relates to an integrated high-efficiency energy storage battery cluster assembly structure. Background Art

[0002] The integrated battery cluster is an integrated, modular energy storage system design designed to improve the efficiency, safety, and economy of energy storage. In today's era, with the advancement of clean, low-carbon energy goals and the increase in installed capacity of new energy sources, the power system faces many challenges, especially the increasingly urgent need for frequency and peak regulation. Unlike traditional centralized energy storage solutions, the integrated battery cluster adopts a string design. Each battery cluster can independently control charging and discharging, effectively preventing bias current from affecting discharge capacity. This design enables each battery cluster to operate independently, optimizing energy distribution and utilization.

[0003] The existing authorized public number is CN212625767U, which discloses an integrated packaging structure and an integrated battery pack. The integrated packaging structure includes a module assembly and a cooling assembly, and the cooling assembly is integrally formed inside the module assembly; the integrated battery pack includes a single cell, a box body and an integrated packaging structure, and multiple groups of the integrated packaging structure are integrally formed inside the box body, and the single cells are arranged in the accommodation space formed by the first baffles arranged at intervals. The integrated battery pack described in the present invention adopts an advanced die-casting process, and the battery pack as a whole can be integrated into one piece. This design greatly improves the production efficiency and product qualification rate of the battery pack, while saving material costs and the cost of connectors and fasteners during battery pack assembly. The assembly is simple and easy, which improves production efficiency. However, the top of the box body in the above-mentioned integrated packaging structure and integrated battery pack is an open structure, which cannot provide good protection for the battery pack therein. Therefore, it is necessary to provide an integrated high-efficiency energy storage battery cluster assembly structure to solve the above-mentioned problems. Utility Model Content

[0027] Preferably, the area of ​​the bottom plate 2 is larger than the bottom area of ​​the housing 1, thereby providing a certain degree of protection for the bottom structure of the housing 1. The top of the fixing rod 4 is set to a hexagonal structure, so that the fixing rod 4 can be rotated to move downward along the fixing tube 3, and then the fixing rod 4 can be inserted and installed into the mounting hole preset on the equipment where the device needs to be installed, which is compatible with the fixing rod 4. Then, the device can be installed and fixed by four groups of fixing rods 4.

[0028] Preferably, a set of fixing rings 5 ​​are installed on the outer side of the top of the shell 1 and the outer side of the bottom of the protective cover 6. The two sets of fixing rings 5 ​​are connected by four sets of fixing bolts provided at the four corners, so that the two sets of fixing rings 5 ​​are fixedly assembled together, and then the protective cover 6 is installed on the top of the shell 1, so that the top space of the shell 1 can be sealed to protect the energy storage battery 16 stored inside the shell 1. The heat dissipation groove opened on the top of the protective cover 6 allows the heat generated by the energy storage battery 16 to escape from the inside of the shell 1, ensuring normal heat dissipation of the energy storage battery 16. At the same time, the dustproof plate 7 can prevent a large amount of dust from entering the interior of the shell 1, thereby protecting the energy storage battery 16.

The two sets of slot plates 10 installed inside the outer shell 1 are arranged on opposite sides with an open structure, and the bottom of the slot plates 10 is arranged with a closed structure. The slots provided inside the slot plates 10 are adapted to the plug blocks 9. By installing the two sets of plug blocks 9 into the slots provided on the two sets of slot plates 10, the inner shell 8 can be installed inside the outer shell 1. At this time, the inner shell 8 will not shake inside the outer shell 1, thereby ensuring the stability of the energy storage battery 16.

[0030] Preferably, the connecting plate 11 and the mounting plate 12 are fixedly connected by two sets of symmetrical fixing bolts. When the inner shell 8 is installed inside the outer shell 1, the plug block 9 is inserted into the slot. At this time, the fixing holes provided on the connecting plate 11 correspond to the fixing holes provided on the mounting plate 12. The two can be fixedly assembled together by the fixing bolts, thereby achieving the fixed installation of the inner shell 8 inside the outer shell 1.

The top of the shock-absorbing device 13 is fixedly connected to the bottom of the mounting plate 12, and the bottom of the shock-absorbing device 13 is fixedly connected to the inner bottom surface of the outer shell 1, so that the mounting plate 12 is installed in the inner bottom space of the outer shell 1. The four groups of shock-absorbing devices 13 can provide a certain buffering and shock-absorbing effect for the entire device. When the external device vibrates, the vibration generated by the inner shell 8 will be transmitted to the shock-absorbing device 13. Through the movement of the oil in the shock-absorbing device 13, the mechanical energy can be converted into internal energy of the oil and dissipated through heat transfer, thereby ensuring that the energy storage battery 16 will not be affected by excessive vibration.

[0032] Preferably, a through groove is provided at the top of the partition plate 14 so that the partition plate 14 can be pulled upward from the inner shell 8. The partition plate 14 can be installed inside the inner shell 8 by means of sliders 15 installed on both sides of the partition plate 14. At this time, the position of the partition plate 14 in the inner shell 8 will not change, so a group of energy storage batteries 16 can be inserted between two adjacent groups of partition plates 14, thereby ensuring that the energy storage batteries 16 in the inner shell 8 will not contact each other, thereby preventing the energy storage batteries 16 from short-circuiting and catching fire due to mutual contact, thereby improving the safety of the device. At the same time, the outer shell 1, the inner shell 8 and the partition plate 14 are all non-combustible, further improving the safety of the device.
