Description

Technical Field

[0001] The utility model relates to the technical field of transportation devices, and in particular to an operation and maintenance tool for an energy storage battery cluster. Background Art

[0002] The battery cluster is an important component of the battery system. It is a battery assembly that is connected in series, parallel or series-parallel by battery cells and connected to energy storage inverters and ancillary facilities to achieve independent operation. The application areas of battery clusters are very wide, including but not limited to electric vehicles, power storage systems, communication base stations, portable electronic devices, power tools, etc. In electric vehicles, battery clusters serve as a power source to provide the vehicle with the power required for driving; in power storage systems, battery clusters are used to store and regulate the power in the power grid.

[0003] With the development of the energy storage industry, the integration of energy storage systems is becoming increasingly higher. From small household storage to industrial and commercial energy storage cabinets, and then to large energy storage containers, the products are getting larger and larger, and the weight of the products is increasing sharply. This makes the assembly and operation and maintenance of the products face major challenges. At present, the battery plug-in box into the cluster is a major problem. The battery plug-in box is usually transported to the battery cluster by forklift, and then manually moved into the cluster. Due to the high battery cluster of large energy storage systems, manual handling efficiency is low and safety accidents are very likely to occur.

[0004] A Chinese patent with application number 202011041381.X discloses a battery box transport tool. The above-mentioned battery box transport tool includes a bottom frame and a positioning mechanism arranged on the bottom frame, and the positioning mechanism includes a support beam, a first limiting angle iron, a second limiting angle iron and a baffle; a support plate is fixed on the bottom frame, and the four angles of the bottom frame are respectively welded with the support beams, and support legs are welded to the bottom of the support beam. The first limiting angle iron is four pieces, which are fixed on the support plate in a square shape, and the second limiting angle iron is two pieces, which are respectively fixed on the upper and lower sides of the support plate, and the baffle is fixed in the middle of the bottom frame. A Chinese patent with application number 202010120135.7 discloses a battery pack transport device.

[0005] The above-mentioned prior art only discloses the fixed limit of the battery pack, which is achieved by the base plate, frame and limit frame. However, manual transportation is required to transport several battery boxes to the battery cluster. Since the battery cluster of a large energy storage system is relatively high, manual transportation is inefficient and is prone to safety accidents. Utility Model Content
