Description

Technical Field

[0001] The utility model relates to the technical field of energy storage cabinets, in particular to an energy storage cabinet which is convenient for hoisting and transporting. Background Art

[0002] As an important component of battery energy storage systems, energy storage battery cabinets have been widely used in new energy, smart grid, energy-saving technologies and other fields. After assembly, energy storage battery cabinets often need to be transported.

[0003] There are two common methods for transporting large cabinets: one is to use a forklift to lift the cabinet from the bottom; the other is to install lifting rings on the top of the cabinet, then hang steel ropes on the lifting rings and use a crane to lift the cabinet for transportation. Currently, the lifting rings installed on existing cabinets all have pre-threaded holes embedded in the top of the cabinet, and then the lifting rings are directly fixed to the cabinet using threaded connections.

[0004] Energy storage cabinets, due to their pursuit of high energy density, are extremely heavy. For an electrical cabinet and energy storage system cabinet of the same volume, for every 1 ton the electrical cabinet weighs, the energy storage system cabinet can weigh 3 to 5 tons. Using the aforementioned lifting ring structure to hoist the energy storage cabinet can lead to a drop due to insufficient connection rigidity, resulting in damage to the cabinet. This is primarily due to the difficulty of the lifting ring forming a primary force transmission system with the main load-bearing beam or frame, making it susceptible to localized damage due to isolated forces. Furthermore, threaded connections are susceptible to loosening during transport vibrations, reducing connection reliability.

[0005] Therefore, existing technologies generally use a forklift to lift the energy storage cabinet from the bottom. However, in places where forklifts are not easily accessible, moving the energy storage cabinet becomes very troublesome. Therefore, it is necessary to design an energy storage cabinet that can be lifted by a forklift and also be suitable for hoisting. Utility Model Content

[0006] In order to solve some or all of the problems existing in the above-mentioned prior art, the utility model provides an energy storage cabinet which is easy to lift and transport, including a load-bearing frame, a protective plate and a protective door are provided on the outer side of the load-bearing frame, the load-bearing frame includes a bottom cross beam frame and a top cross beam frame, the lower end of the bottom cross beam frame is provided with a plurality of supporting feet of the same height, the upper end of the bottom cross beam frame is provided with a plurality of load-bearing columns, the other ends of the load-bearing columns are respectively connected to the top cross beam frame, a plurality of lifting parts are provided on the upper end surface of the top cross beam frame, and the lifting parts are arranged in a one-to-one correspondence with the load-bearing columns; avoidance holes are respectively provided at positions corresponding to the lifting parts on the top cross beam frame, and the lifting parts are welded and fixed to the load-bearing columns after passing through the corresponding avoidance holes, and the lifting parts are sealed and connected to the top cross beam frame.

[0007] As a further improvement of the present invention, the hanging part is provided with a slot adapted to the shape of the load-bearing column, the load-bearing column is engaged with the slot, and the side wall of the slot is welded and fixed to the load-bearing column.

[0008] As a further improvement of the present invention, the outer side wall of the hanging member is welded and sealed to the top crossbeam.

[0009] As a further improvement of the present invention, a hanging rope hole is provided on the hanging piece.

[0010] As a further improvement of the present invention, there are four of the hoisting parts and four of the load-bearing columns, and the two are arranged in a one-to-one correspondence. The four load-bearing columns are distributed in a rectangular shape on the bottom cross beam frame.

[0011] As a further improvement of the present invention, the hanging piece is a steel plate with an integrated structure, and the thickness of the hanging piece is 8-15 mm.

[0012] As a further improvement of the present invention, a support plate is provided on the lower end surface of the support foot.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] This utility model can be lifted and transported by forklift. On the other hand, the lifting parts are welded and fixed to the load-bearing columns, thereby improving the overall structural rigidity. During the lifting process, each load-bearing column can bear the force, reducing the risk of damage to the cabinet body due to a single point on the cabinet body being subjected to force.

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it necessarily refer to mutually exclusive, independent, or alternative embodiments to other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this disclosure may be combined with other embodiments.

[0023] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown, an energy storage cabinet that is easy to lift and transport includes a load-bearing frame. The outer side of the load-bearing frame is provided with a protective plate 1 and a protective door 2. By providing the protective plate 1 and the protective door 2, the battery pack and other electrical components can be encapsulated to reduce the erosion of moisture and dust. By opening or closing the protective door 2, the battery pack and other components inside the energy storage cabinet can be easily loaded, unloaded and maintained. The load-bearing frame includes a bottom crossbeam frame 3 and a top crossbeam frame 4. The lower end of the bottom crossbeam frame 3 is equipped with multiple support legs 5 of the same height. The support legs 5 facilitate the stable placement of the energy storage cabinet on the ground or a table. The support legs 5 make the energy storage cabinet suitable for forklift transportation. Specifically, the forklift can be inserted into the gap between the support legs 5 to drive the forklift to lift the bottom crossbeam frame 3, thereby lifting the energy storage cabinet and achieving forklift transportation.

[0025] In order to improve the stability of the energy storage cabinet when placed on the ground or table, a support plate 6 is installed at the lower end of the support foot 5; by providing the support plate 6, the contact area between the energy storage cabinet and the ground or table can be increased, so that it can be placed more stably on the ground or table, thereby improving practicality.

[0026] The upper end of the bottom crossbeam 3 is provided with a plurality of load-bearing columns 7, the other ends of which are respectively connected to the top crossbeam 4. The upper end surface of the top crossbeam 4 is provided with a plurality of lifting parts 8, which are arranged in a one-to-one correspondence with the load-bearing columns 7. By providing the lifting parts 8, the energy storage cabinet can be suitable for lifting and transportation. In order to ensure the stability of lifting and transportation, avoidance holes 41 are respectively provided on the top crossbeam 4 at the positions corresponding to the lifting parts 8. The lifting parts 8 are welded and fixed to the load-bearing columns 7 after passing through the corresponding avoidance holes 41, and the lifting parts 8 are sealed with the top crossbeam 4. By welding and fixing the lifting parts 8 to the corresponding load-bearing columns 7, each load-bearing column 7 can be subjected to force during the lifting process, reducing the risk of damage to the cabinet body caused by only a certain point on the cabinet body being subjected to force; at the same time, the problem of loose threaded connections is also avoided. During lifting and transportation, the lifting ropes are hung on each lifting part 8, and the cabinet can be lifted and transported by a crane.

[0027] The energy storage cabinet can be lifted and transported by a forklift, and can also be used for hoisting and transporting by hanging a lifting rope on the lifting part 8, so that it can be conveniently transported in some places where forklifts are not convenient to enter, thereby improving practicality and meeting usage needs in different situations.

[0028] In order to improve the installation stability of the hanging member 8 on the load-bearing column 7, in this embodiment, a card slot 81 that is adapted to the shape of the load-bearing column 7 is provided on the hanging member 8; during the assembly process, after the hanging member 8 passes through the corresponding avoidance hole 41, each load-bearing column 7 is respectively inserted into the card slot 81 of the corresponding hanging member 8 for card connection, and the matching gap between the side wall of the card slot 81 and the load-bearing column 7 is fully welded, so that the load-bearing column 7 and the hanging member 8 are welded and fixed. By providing the card slot 81, on the one hand, it is convenient to quickly install and position the load-bearing column 7 and the hanging member 8, and on the other hand, it also increases the contact area between the load-bearing column 7 and the hanging member 8, thereby increasing the welding area and improving the connection stability between the load-bearing column 7 and the hanging member 8.

[0029] In this embodiment, the hoisting member 8 is a steel plate with an integrated structure, and the thickness of the hoisting member 8 is 8-15 mm. Its strength is far greater than the strength requirement for hoisting the energy storage cabinet, and it is suitable for various high-strength hoisting.

[0030] After the hanging part 8 passes through the avoidance hole 41, the outer wall of the hanging part 8 is fully welded and sealed with the inner wall of the corresponding avoidance hole 41, so that the hanging part 8 and the top crossbeam frame 4 are welded and sealed, preventing water vapor and dust from entering the cabinet through the matching gap between the avoidance hole 41 and the hanging part 8, thereby ensuring the safety of electrical work in the cabinet.

[0031] In order to facilitate hoisting, a hanging rope hole 82 is provided on the hoisting member 8 ; when hoisting, a hook or a hanging rope on the crane can be passed through the hanging rope hole 82 , thereby facilitating the hoisting of the energy storage cabinet through the hoisting member 8 .

[0032] To further enhance hoisting stability, in this embodiment, there are four hoisting members 8 and four load-bearing columns 7, each of which is arranged in a one-to-one correspondence. The four load-bearing columns 7 are distributed in a rectangular shape on the bottom crossbeam 3. By providing four hoisting members 8 and four load-bearing columns 7, the load-bearing frame can be subjected to force at four points during hoisting, distributing the weight of the energy storage cabinet to the four hoisting members 8. This reduces the force on a single hoisting member 8 and improves hoisting safety and stability.

[0033] Working principle:

[0034] When the energy storage cabinet needs to be transported by forklift, the forklift's fork is simply inserted into the gaps between the support legs 5, which can then be driven to lift the bottom crossbeam 3, thereby lifting the energy storage cabinet and achieving forklift transportation. If a crane is used for lifting, a lifting rope or a hook equipped with a lifting rope can be passed through the hanging rope holes 82 of each lifting member 8, and the other end of the lifting rope or hook is hung on the crane. The crane can then be driven to lift the energy storage cabinet, thereby achieving lifting transportation.

[0035] The above-mentioned specific implementation manner is a preferred implementation manner of the present utility model, and is not intended to limit the specific implementation scope of the present utility model. The scope of the present utility model includes but is not limited to the specific implementation manner. All equivalent changes made in accordance with the present utility model are within the protection scope of the present utility model.
