In recent years, energy storage battery technologies such as lithium-ion batteries, lead-acid batteries, and flow batteries have been continuously developed. The performance of batteries, such as energy density, cycle life, and safety, has been continuously improved, and the cost has been continuously reduced, providing strong technical support for the development of energy storage cabinets; During the transportation of traditional large integrated energy storage cabinets, due to their large volume and weight, special transportation equipment and high transportation costs are often required, which increases the transportation cost and logistics difficulty and reduces the transportation efficiency. Summary of the Invention

[0003] Object of the Invention: The object of the present invention is to solve the problem that during the transportation of traditional large integrated energy storage cabinets, due to their large volume and weight, the transportation cost and logistics difficulty are increased, and the transportation efficiency is reduced.

[0004] Technical Solution: A detachable combined energy storage cabinet includes a support bottom plate. The upper surface of the support bottom plate is fixedly connected with a cabinet one, and a cabinet two is arranged on the upper surface of the cabinet one; Fixing plates are symmetrically and fixedly connected to the upper surfaces of the cabinet one and the cabinet two. Plugging grooves are symmetrically opened on the lower surfaces of the cabinet one and the cabinet two. The upper surfaces of the two fixing plates above the cabinet one respectively extend into the interiors of the two plugging grooves below the cabinet two. A transverse groove is commonly opened between the two plugging grooves on the same horizontal plane, and an air delivery pipe is commonly fixedly connected to the opposite sides of the two fixing plates on the same horizontal plane.

[0005] Furthermore, a plurality of universal wheels are symmetrically and fixedly connected to the lower surface of the support bottom plate.

[0006] Furthermore, storage cavities are opened on the front surfaces of the cabinet one and the cabinet two. Sealing doors are rotatably connected to the front surfaces of the cabinet one and the cabinet two and located in front of the two storage cavities through hinges. Battery modules are arranged inside the two storage cavities.

[0007] Furthermore, sliding chambers are integrally formed above the two storage chambers inside the cabinet one and the cabinet two. Piston plates one are slidably connected inside the two sliding chambers. Rotating handles are provided at the rear of the cabinet one and the cabinet two. Connecting rods are fixedly connected to the front surfaces of the two rotating handles. The front ends of the connecting rods extend into the sliding chambers and are fixedly connected to rotating sleeves. A moving block is threadedly connected inside the rotating sleeve. An activity rod is fixedly connected to the common front surface of the moving block and the rear surface of the piston plate one. The inner parts of the two sliding chambers are fixedly connected to the outer side walls of the two air delivery pipes respectively.

[0008] Furthermore, a limiting groove is formed above the outer side wall of the activity rod. A limiting rod is fixedly connected to the inner upper surface of the sliding chamber and behind the piston plate one. The bottom end of the limiting rod is slidably connected to the inner lower surface of the limiting groove.

[0009] Furthermore, an observation window is integrally formed on the front surface of the sealing door. A pulling groove is formed on the front surface of the sealing door and to the right of the observation window.

[0010] Furthermore, activity chambers are symmetrically formed inside the fixing plate. Piston plates two are slidably connected inside the two activity chambers. Penetrating extension openings are formed on the opposite sides inside the two activity chambers. Locking plates are fixedly connected to the opposite sides of the two piston plates two. Locking grooves are formed on the inner front surface and the inner rear surface of the plugging groove. A ventilation groove is formed inside the two activity chambers and is communicated with the air delivery pipe.

[0012] Beneficial effects: The energy storage cabinet adopts a detachable combined design and is composed of a support bottom plate, a cabinet one, and a cabinet two. It can be disassembled for transportation. Compared with traditional large integrated energy storage cabinets, the transportation volume and weight are greatly reduced, thereby reducing the transportation cost, reducing the logistics difficulty, and improving the transportation efficiency. At the same time, the cabinets can be stacked repeatedly, increasing the storage quantity of the energy storage cabinet for battery modules, thus enhancing the convenience and practicality of the device; Storage chambers are provided on the front surfaces of the cabinets and are closed by sealing doors rotatably connected by hinges. Battery modules are arranged inside. This independent storage method facilitates the installation, disassembly, maintenance, and repair of individual battery modules. At the same time, the sealing doors can protect the battery modules, preventing dust, foreign objects, etc. from entering and affecting the battery performance. Moreover, the battery modules are stored separately in different cabinets, reducing the possibility of the spread of safety risks caused by the failure of a certain battery module throughout the energy storage system, and improving the safety and reliability of the energy storage system; By rotating the rotating handle at the rear of the cabinet, the piston plate 1 can be driven to move, and air is supplied to the movable cavity in the fixed plate through the air pipe, pushing the piston plate 2 to insert the locking plate into the locking groove, realizing the stable locking of the stacked cabinets, ensuring the stability and safety of the cabinets when used in combination, avoiding the separation of the cabinets caused by accidental collisions, etc. At the same time, this structure is convenient to operate and disassemble, improving the flexibility and convenience of the cabinet use.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] In order to make the technical solutions of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] Embodiment As Figure 1 shown, a plurality of universal wheels 6 are symmetrically fixedly connected to the lower surface of the support bottom plate 1; The plurality of universal wheels 6 provided enable the energy storage cabinet to easily achieve free steering and movement on various ground environments, that is, the position can be frequently changed according to the changes in the working site, the adjustment of the equipment layout, or the needs of maintenance and repair, providing great convenience.

[0017] As Figure 1 , Figure 3 and Figure 4As shown in the figure, a detachable combined energy storage cabinet is provided, which includes a support bottom plate 1. The upper surface of the support bottom plate 1 is fixedly connected with a cabinet one 2. A cabinet two 3 is arranged on the upper surface of the cabinet one 2. Fixing plates 4 are symmetrically and fixedly connected to the upper surfaces of both the cabinet one 2 and the cabinet two 3. Plug-in slots 5 are symmetrically opened on the lower surfaces of both the cabinet one 2 and the cabinet two 3. The upper surfaces of the two fixing plates 4 above the cabinet one 2 respectively extend into the two plug-in slots 5 below the cabinet two 3. A transverse slot 10 is jointly opened between the two plug-in slots 5 located on the same horizontal plane. An air delivery pipe 11 is jointly fixedly connected to the opposite sides of the two fixing plates 4 located on the same horizontal plane; Fixing plates 4 are symmetrically and fixedly connected to the upper and lower surfaces of both the cabinet one 2 and the cabinet two 3 respectively, and plug-in slots 5 are opened. The upper surfaces of the two fixing plates 4 above the cabinet one 2 respectively extend into the two plug-in slots 5 below the cabinet two 3. A transverse slot 10 is jointly opened between the two plug-in slots 5 located on the same horizontal plane. An air delivery pipe 11 is jointly fixedly connected to the opposite sides of the two fixing plates 4 located on the same horizontal plane. Thus, by stacking the cabinet two 3, a combined design can be realized, which is convenient for logistics transportation and improves transportation efficiency.

[0018] As Figure 1 and Figure 2 shown in the figure, storage cavities 7 are opened on the front surfaces of both the cabinet one 2 and the cabinet two 3. Sealing doors 8 are rotatably connected to the front surfaces of both the cabinet one 2 and the cabinet two 3 and located in front of the two storage cavities 7 through hinges. Battery modules 9 are arranged inside both the two storage cavities 7; Storage cavities 7 closed by sealing doors 8 rotatably connected by hinges are provided on the front surfaces of both the cabinet one 2 and the cabinet two 3. Battery modules 9 are respectively arranged inside the two storage cavities 7. Thus, independent storage of the battery modules 9 by the cabinet can be realized. On the one hand, the sealing doors 8 can play a protective role for the battery modules 9, preventing dust, foreign objects, etc. from entering and affecting the battery performance. On the other hand, the independent storage cavities 7 are convenient for the installation, disassembly, maintenance and repair of individual battery modules 9. At the same time, dispersing the battery modules 9 for storage in different cabinets reduces to a certain extent the possibility of the spread of safety risks caused by the failure of a certain battery module 9 in the entire energy storage system, and improves the safety and reliability of the energy storage system.

[0019] As Figure 1 shown in the figure, heat dissipation nets 29 are embedded and installed on the right sides of both the cabinet one 2 and the cabinet two 3; During the operation of the battery modules 9 and other electrical equipment inside the energy storage cabinet, a large amount of heat will be generated. Thus, the heat can be exchanged with the external air through the heat dissipation nets 29, preventing the battery modules 9 from reducing the charge and discharge efficiency due to overheating and even causing potential safety hazards.

[0020] As Figures 1-5As shown in the figure, sliding chambers 12 are integrally formed above the two storage chambers 7 inside the cabinet one 2 and the cabinet two 3. A first piston plate 13 is slidably connected inside each of the two sliding chambers 12. Rotating handles 14 are provided at the rear of the cabinet one 2 and the cabinet two 3. Connecting rods 15 are fixedly connected to the front surfaces of the two rotating handles 14. The front ends of the connecting rods 15 extend into the sliding chambers 12 and are fixedly connected to rotating sleeves 16. A moving block 17 is threadedly connected inside the rotating sleeve 16. An active rod 18 is fixedly connected to the common front surface of the moving block 17 and the rear surface of the first piston plate 13. The outer sides of the two sliding chambers 12 are fixedly connected to the outer side walls of the two air pipes 11 respectively. A limiting groove 19 is formed above the outer side wall of the active rod 18. A limiting rod 20 is fixedly connected to the upper surface inside the sliding chamber 12 and behind the first piston plate 13. The bottom end of the limiting rod 20 is slidably connected to the lower surface inside the limiting groove 19. Activity chambers 23 are symmetrically formed inside the fixing plate 4. A second piston plate 24 is slidably connected inside each of the two activity chambers 23. Penetrating extension ports 25 are formed on the opposite sides inside the two activity chambers 23. Locking plates 26 are fixedly connected to the opposite sides of the two second piston plates 24. Locking grooves 27 are formed on the front surface and the rear surface inside the insertion slot 5. A ventilation groove 28 is formed inside the two activity chambers 23. The ventilation groove 28 is communicated with the air pipe 11; By rotating the rotating handle 14, the rotating handle 14 controls the rotation of the rotating sleeve 16 through the provided connecting rod 15. When the rotating sleeve 16 rotates, the active rod 18 can be extended through the sliding limit of the provided limiting groove 19 and the limiting rod 20, so as to drive the first piston plate 13 to move, ventilate the two activity chambers 23 through the air pipe 11, and then push the second piston plate 24 to insert the locking plate 26 into the locking groove 27, realizing the locking of the upper cabinet, so as to quickly and firmly lock the stacked cabinets, ensuring the stability and safety of the cabinets during combined use, avoiding the separation of the cabinets caused by accidental collision, etc., and being convenient for disassembly at the same time, improving the flexibility and convenience of the cabinet use. When the cabinet needs to be disassembled, the upper cabinet can be removed by reversely rotating the provided rotating handle 14, which is convenient for the device logistics transportation and later storage, and further improves the flexibility and practicality of the device.

[0021] As Figure 1 and Figure 3 shown in the figure, an observation window 21 is integrally formed on the front surface of the sealing door 8, and a pulling groove 22 is formed on the front surface of the sealing door 8 and on the right side of the observation window 21; Through the provided observation window 21, the operator can directly observe the working state of the battery module 9 in the storage chamber 7 without opening the sealing door 8, so as to timely discover potential safety hazards and equipment failures, improve the operation safety and maintenance efficiency of the energy storage cabinet, and at the same time, the operation of the sealing door 8 is made more labor-saving and convenient through the provided pulling groove 22, which can greatly improve the work efficiency.
