Description

Technical Field

[0001] This utility model relates to the field of container structure technology, and in particular to the energy storage container chassis and energy storage container. Background Technology

[0002] Energy storage containers require lifting during transportation, installation, and maintenance. Currently, most energy storage containers employ two lifting methods: one is lifting from the four corner brackets at the top, and the other is lifting from the bottom using a pipe-through method with lifting points set in the middle of the container's bottom beams. However, the top corner bracket lifting method places high demands on the structural strength of the energy storage container, resulting in complex structural design, large steel consumption, and high processing costs. The bottom pipe-through method with lifting points set in the middle of the container's bottom beams requires a large operating space within the container, leading to a large project footprint and low overall energy density.

[0003] Therefore, there is an urgent need for an energy storage container chassis and energy storage container with high rigidity, large rated load, and small deformation during lifting. Utility Model Content

[0004] Objective: In order to overcome the shortcomings of the existing technology, this utility model provides an energy storage container chassis and an energy storage container. The chassis has high strength and good stability, and the energy storage container has strong load-bearing capacity.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] In a first aspect, this utility model provides an energy storage container chassis, which is a rectangular structure and includes bottom side beams, a bottom plate, longitudinal beam assemblies, end beam assemblies, and container corner pieces; Two bottom side beams are provided, which are arranged parallel to each other on both sides of the energy storage container chassis; the bottom side beams extend along the length of the energy storage container chassis. The base plate is installed between two bottom side beams; The longitudinal beam assembly includes a first longitudinal beam, a second longitudinal beam, and a third longitudinal beam, all extending along the length of the energy storage container chassis. The first longitudinal beam, the second longitudinal beam, and the third longitudinal beam are arranged in sequence. The first longitudinal beam is located inside the bottom side beam, the second longitudinal beam is located in the middle of the width direction of the energy storage container chassis, and the third longitudinal beam is located between the second longitudinal beam and the bottom side beam. The end beam assembly includes a first end beam and a second end beam, both disposed between two bottom side beams; the first end beam is connected to one end of the two bottom side beams and the second longitudinal beam, and the second end beam is connected to the other end of the two bottom side beams and the second longitudinal beam, as well as the ends of the first longitudinal beam and the third longitudinal beam. The energy storage container chassis is equipped with container corner fittings at its four corners.

[0007] The energy storage container chassis provided by this utility model, through the combined design of bottom side beams, bottom plate, longitudinal beam assembly and end beam assembly, ensures the rigidity and strength of the energy storage container while reducing the amount of steel used, and is not prone to deformation during use; the energy storage container chassis is provided with container corner fittings at the four corners, and the lifting design of the four bottom corner fittings can realize the back-to-back installation of energy storage containers with single-side doors, requiring little space for lifting operations, resulting in a small footprint and high overall energy density of the project.

[0008] In some embodiments, the first longitudinal beam is a square tube, a flat plate, or an H-beam; The second longitudinal beam is an H-beam; The third longitudinal beam is a square tube, a flat plate, or an H-beam.

[0009] H-beams can avoid the drawbacks of increased steel consumption, high processing costs, increased container weight, sharp increase in transportation costs, and reduced rated load, while ensuring that the installation of the base frame and energy storage equipment is not affected.

[0010] In some embodiments, the lengths of the first and third longitudinal beams are less than the length of the second longitudinal beam.

[0011] In some embodiments, the energy storage container chassis further includes an angled bottom plate, which is disposed inside the first end beam between two bottom side beams and above the first longitudinal beam, the second longitudinal beam, and the third longitudinal beam.

[0012] In some embodiments, the energy storage container chassis further includes multiple floor drains, which are disposed on the bottom plate between the third longitudinal beam and the bottom side beam, and on the angled bottom plate, for draining liquid inside the container.

[0013] In some embodiments, multiple bottom longitudinal beams are provided at parallel intervals between the first longitudinal beam and the second longitudinal beam, and between the third longitudinal beam and the second longitudinal beam.

[0014] In a second aspect, this utility model provides an energy storage container, comprising: an energy storage container frame, a battery compartment, and an equipment compartment as described in the first aspect; The battery compartment and equipment compartment are installed above the energy storage container's underframe, with the equipment compartment installed on the side closer to the first end beam and the battery compartment installed on the side closer to the second end beam. The battery compartment is equipped with a battery cluster rack.

[0015] In some embodiments, the battery cluster rack is vertically mounted on the energy storage container chassis and includes: cluster rack side beams, cluster rack longitudinal beams, and multiple unit box support plates; The cluster frame side beams are provided with two beams, which are installed perpendicular to the base plate above the first longitudinal beam and the third longitudinal beam, respectively; The cluster frame longitudinal beam is located between the two cluster frame side beams and is installed perpendicular to the bottom plate above the second longitudinal beam; The two ends and the middle part of the unit box support plate are fixedly connected to the side beams and longitudinal beams of the cluster frame, respectively. The unit box support plate is parallel to the bottom plate and is used to store energy storage batteries.

[0016] In some embodiments, the battery cluster rack further includes reinforcing ribs, which are obliquely installed on the battery cluster rack, with one end connected to the energy storage container base frame near the end of the longitudinal beam of the cluster rack, and the other end connected to the end of the side beam of the cluster rack.

[0017] Beneficial Effects: The energy storage container chassis provided by this utility model, through the combined design of bottom side beams, bottom plate, longitudinal beam assemblies, and end beam assemblies, improves the structural strength and load-bearing capacity of the energy storage container chassis, while reducing the amount of steel used and minimizing deformation during use. During lifting, the longitudinal strength of the bottom side beams increases the overall longitudinal stiffness of the chassis. The chassis features container corner fittings at the four corners, and the lifting design of these four corner fittings allows for back-to-back installation of energy storage containers with single-side doors, requiring minimal space for lifting operations, resulting in a smaller footprint and higher overall energy density for the project. The energy storage container provided by this utility model, including this energy storage container chassis, improves the stability and reliability of the energy storage container while meeting its functional requirements.
