[0002] An energy storage container is a standardized container integrating a battery energy storage system and other related devices, which is used for efficiently and safely storing and managing electric power. They are widely used in scenarios such as power dispatching, load balancing, standby power supply, etc.

[0003] A vanadium battery energy storage container is an energy storage system that installs a vanadium redox flow battery (VRB) in a standardized container and realizes rapid deployment and efficient management through highly integrated design. It is an integrated and modular energy storage system. At present, the components of a vanadium battery energy storage container generally include key parts such as an electrolyte storage tank, an electrostack, an energy management system, an energy storage converter, and a thermal management system, etc. As the main component, the electrostack often needs to be repaired during use. When the energy storage container is designed initially, its space is generally designed relatively fully. Since explosion-proof devices, constant temperature devices, or fire extinguishing devices, etc. in the energy storage container generally also need to occupy a certain space, there is not much extra space for each structure, especially for the electrostack. Therefore, it is inconvenient to repair or replace the battery, etc. Content of the Utility Model

[0004] The main purpose of the utility model is to provide an energy storage container, in which a support device is installed at the bottom of the electrostack in the energy storage container. This device can facilitate maintenance personnel to perform operations such as repairing or replacing the electrostack, and can achieve the above purposes through simple operations while occupying a small space.

[0005] To achieve the above purpose, the utility model provides an energy storage container, which includes a housing and an electrostack, an inverter, a control device, a cooling system, and electrical accessories located inside the housing. A support device is provided at the bottom of the electrostack. The support device includes a base and a support seat. A groove is provided on the upper end surface of the base, and the electrostack is located in the groove. A plurality of moving devices are fixedly provided on the lower bottom surface of the base. A chute is provided on the support seat, and the moving devices are slidably located in the chute. Clamping members are provided at both ends of the chute. Handles are provided on the front and rear end surfaces of the base.

[0006] Further, the moving device includes a support column, a buffer shaft, a connecting plate, a connecting shaft, and a pulley. The upper end of the support column is fixedly connected to the lower bottom surface of the base, and the lower end is connected to the buffer shaft. The connecting plate is in a U shape, and the pulley is sleeved on the outer periphery of the connecting shaft. Both ends of the connecting shaft are fixed on the connecting plate.

[0007] Further, the buffer shaft includes a sleeve and a plurality of springs fixed on the inner bottom surface of the sleeve. The lower end of the support column is sleeved in the sleeve, and the lower end of the support column is fixedly connected to the spring.

[0008] Furthermore, the slide groove includes a first slot and a second slot, the width of the first slot is smaller than that of the second slot, the support column and the buffer shaft are located in the first slot, and the connecting plate and the pulley are located in the second slot.

[0009] Furthermore, the clip is movably mounted on the front and rear end surfaces of the support seat through buckles, movable hinges or locks.

[0010] Furthermore, a ventilation device is provided on the shell, which includes a vent, a fan and a dust cover. The inside and outside of the shell are connected through the vent, the fan is located in the vent, and the dust cover is fixed on the outside of the fan.

[0011] Through the above technical solution, the beneficial effects of the present invention include: the energy storage container of the present invention is equipped with a support device at the bottom of the battery stack. On the one hand, the support device can improve the stability of the battery stack, especially prevent the battery stack from being bumped and damaged during transportation.
