Description

Technical Field

[0001] The utility model relates to the field of energy storage, in particular to a marine energy storage box. Background Art

[0002] With the continuous breakthrough and development of battery technology, as the core of green new energy ship power, containerized marine battery boxes provide power for the whole ship power and life of coastal and inland river feeder shipping ships, achieving true zero emissions, low noise, high energy efficiency and other advantages. It is imperative to vigorously develop marine containers for pure electric ships. Pure electric ships have higher transmission efficiency, which can effectively reduce energy consumption and reduce operating costs. The energy transmission process of diesel ships is that the diesel engine converts the chemical in diesel into mechanical energy, which is then transmitted to the propeller through the gearbox and shaft system, and then converted into the kinetic energy of the ship. Pure electric ships convert the electrical energy in the battery into mechanical energy on the propeller through the electric motor, and then into the kinetic energy of the ship. The intermediate conversion and transmission process is reduced, and the energy loss is effectively reduced, thereby achieving the goal of energy saving. As an important part of pure electric ships, marine battery boxes will have broad application prospects.

[0003] In the energy storage box, battery racks and batteries are generally arranged on both sides, with a pedestrian walkway in the middle. The installation, removal and maintenance of the battery pack are mainly completed through the middle passage. In the field of marine energy storage boxes, due to the special requirements of marine battery boxes, it is necessary to take into account the regulations of the shipping industry and the energy storage industry. According to the current regulations of the classification society, the battery pack must have a clearance distance of at least 150mm from the inner wall of the box. Accordingly, the middle aisle has been narrowed by 300mm, making it difficult to install the existing battery pack normally. Utility Model Content

Figure 2 An internal side view of a marine energy storage box according to an embodiment of the present disclosure is shown when a battery rack slides close to a side wall of the box.

[0020] Please refer to Figure 1The marine energy storage box comprises a box body 1, which is typically a container, and its six sides enclose a closed internal space 2, wherein at least one end of the box body 1 has an openable door.

[0021] Please continue to refer to Figure 1 Two rows of battery racks 3 are arranged alternately along the width direction of the internal space 2 of the box body 1. The interval between the two rows of battery racks 3 can be used as a pedestrian passage. Optionally, in the length direction of the box body 1, each row of battery racks 3 can include one or more battery racks 3, such as one, two, three, four or even more. The battery racks 3 are equipped with energy storage battery packs for energy storage.

[0022] exist Figure 1 In the figure, the bottom frame 9 of the box body 1 has a guide rail 4 extending along the width direction of the box body 1, and each row of battery racks 3 is slidably set on the guide rail 4. Each row of battery racks 3 is releasably fixed at a position a first set distance W1 away from the adjacent side wall 8 of the box body 1, and the first set distance W1 is not 0.

[0023] At least two guide rails 4 are provided under each battery rack 3, and the battery rack 3 can slide on the guide rails 4, so that the distance between the battery rack 3 and the side wall 8 of the box body 1 and the width of the pedestrian passage can be adjusted. Figure 1 As shown, a slider 5 is provided at the bottom of the battery rack 3, and the slider 5 is slidably matched with the guide rail 4. When the energy storage box is in use, the battery rack 3 is fixed. When the battery pack needs to be installed, the battery rack 3 can be released, and then the battery rack 3 can be pushed to both sides along the guide rail 4 to increase the width of the pedestrian passage between the two rows of battery racks 3. When the energy storage box is in use, the distance from the battery rack 3 to the adjacent side wall 8 of the box body 1 is a first set distance W1, wherein the first set distance W1 can be set according to actual needs. Such actual needs can be derived from industry regulations. Typically, the first set distance W1 can be limited to at least 150 mm according to the current regulations of the classification society.
