[0001] The present application relates to the technical field of energy storage cabinets, and in particular to an energy storage cabinet. Background Art

[0002] In recent years, the demand for industrial and commercial energy storage systems has been growing continuously. As an efficient and reliable energy storage solution, the industrial and commercial energy storage liquid-cooled cabinet has received extensive attention.

[0003] The industrial and commercial energy storage liquid-cooled cabinet usually consists of an electrical compartment, a PCS (Power Conversion System), a high-voltage box, a battery PACK (battery pack), and a liquid-cooling unit. In the existing technical solutions, the high-voltage box, the electrical compartment, the PCS, and the liquid-cooling unit are usually placed in the same cabinet body. Among them, components such as the PCS and the liquid-cooling unit usually need to exchange air through the air inlet and outlet to achieve self-cooling. However, the inlet and outlet gases of components such as the PCS or the liquid-cooling unit may contain impurities such as dust and water vapor, and the discharged gases of components such as the PCS or the liquid-cooling unit will also carry a certain amount of heat. These factors will affect the electrical components in the electrical compartment, resulting in electrical component failures or shortened service lives.

[0004] Therefore, there is an urgent need for an energy storage cabinet design solution that can effectively isolate the electrical compartment from other equipment, ensure the safe operation of electrical components, and improve the overall performance and reliability of the energy storage system. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present application is to provide an energy storage cabinet, which has the advantage of protecting the electrical compartment to extend its service life.

[0006] The above object of the present application is achieved through the following technical solutions:

[0007] An energy storage cabinet, comprising an electrical compartment and a unit component arranged in the same cabinet body, wherein the unit component is provided with air vents, the electrical compartment has a working surface, and electrical components are arranged on the working surface. Among them, a maintenance board is arranged on the working surface of the electrical compartment, and the maintenance board shields the electrical components on the working surface to block the contact between the airflow formed at the air vents and the electrical components.

[0008] By adopting the above technical solution, the contact between the electrical components and the gases inhaled or discharged from the air vents is blocked by setting the maintenance board, realizing the function of protecting the electrical components, which helps to reduce the erosion of dust, foreign objects, etc. on the electrical components. In addition, for heat dissipation purposes, the gases discharged from the air vents will carry a certain amount of heat, and the contact of such gases with the electrical components will also affect the use of the electrical components.

[0009] Adopting the above technical solution, the service life of the electrical component is prolonged, the risk of pollution or damage caused by air flow is reduced, the possibility of system failure of the electrical component is decreased, and the safety and stability of the overall operation are improved.

[0010] The present application is further configured such that a groove is provided on the acting surface, the electrical component is disposed in the groove, and the maintenance board is connected to the acting surface and seals the groove.

[0017] Furthermore, the upper outer edge part and the maintenance board at the upper end of the window are connected by a hinge, and the lower outer edge part and the maintenance board at the lower end of the window are connected by a non-loosening screw.

[0018] Adopting the above technical solution is convenient for operation. The connection between the upper outer edge part and the hinge allows the flexible opening of the cover board and can also adjust different covering states according to the usage scenario.

[0019] This application is further configured such that the number of the grooves is multiple, and the number of the maintenance boards matches the number of the grooves.

[0020] Adopting the above technical solution, according to the types of the electrical components in the electrical appliance bin, they can be classified and arranged in different grooves, and the electrical components in other grooves will not be affected during the maintenance and use processes.

[0021] Adopting the above technical solution, multiple grooves and the matching maintenance boards are provided in a set, which can improve the space utilization efficiency and facilitate the installation and maintenance of the equipment.

[0022] This application is further configured such that the maintenance board and the acting surface are connected by hand-tightening screws.

[0023] Adopting the above technical solution, by connecting the maintenance board and the acting surface with the hand-tightening screws, it is easy to install and disassemble.

[0039] The following further elaborates on this application with reference to the drawings.

[0040] like Figures 1 to 2 As shown, an energy storage cabinet is provided, wherein a chamber is formed inside the energy storage cabinet, and the energy storage cabinet comprises an electrical chamber 1 and a unit component 2, wherein the electrical chamber 1 and the unit component 2 are arranged in the same chamber, and an air vent X is provided on the unit component 2, and the air vent X takes in or exhausts air to achieve functions such as heat dissipation or ventilation, and an air flow is formed in the process of the air vent X sucking in or exhausting gas, and the electrical chamber 1 has an action surface Y, and a groove 13 is provided on the action surface Y, and an electrical component 12 is arranged in the groove 13, and a maintenance plate 11 is detachably connected to the action surface Y, and the maintenance plate 11 forms an obstacle to the contact between the air flow and the electrical component 12.

[0041] On the one hand, by setting up the maintenance plate 11, the contact between the electrical components 12 and the gas sucked in or discharged from the air outlet X is cut off, thereby achieving the function of protecting the electrical components 12 and helping to reduce the erosion of dust, foreign matter, etc. on the electrical components 12; if the exhaust gas of components such as PCS21 or liquid cooling unit realizes the heat exchange function, it will also carry a certain amount of heat, and the contact between the hot gas and the electrical components 12 will also affect the use of the electrical components 12. The maintenance plate 11 cuts off the direct contact between the electrical components 12 and such gas, thereby extending the service life of the electrical components 12, reducing the possibility of system failure of the electrical components 12, and improving the safety and stability of the overall operation.

[0042] On the other hand, a groove 13 is provided on the active surface Y and the electrical component 12 is placed therein to form an accommodating space. It is difficult for the unit component 2 to be directly blown into the groove 13, and the possibility of the electrical component 12 being affected by the airflow when it is arranged in the groove 13 is further reduced. In addition, the maintenance plate 11 is connected to the active surface Y to block the groove 13, thereby forming further protection for the electrical component 12. The maintenance plate 11 and the active surface Y roughly form a plane, which is smooth as a whole and has a strong sense of unity. Airflow, water vapor, dust, etc. are not easy to enter, thereby reducing the frequency of maintenance and replacement of components.

[0043] Preferably, the maintenance plate 11 and the active surface Y are detachably connected by bolts; preferably, the maintenance plate 11 and the active surface Y are detachably connected by snap-fitting; more preferably, the maintenance plate 11 and the active surface Y are detachably connected by hand screws 113, which are easy to install and disassemble. The hand screws 113 make the maintenance process simple and quick, and the user can easily install and disassemble, thereby improving the maintenance efficiency.

[0044] like Figures 3 to 4 As shown, a window 111 is opened on the maintenance plate 11 , and a cover plate 112 is connected to the maintenance plate 11 , and the cover plate 112 blocks the window 111 .

[0045] The setting of the shielding plate 112 further improves the convenience and flexibility of maintenance and use. By opening a window 111 on the maintenance board 11, it is convenient to observe, connect, locally inspect, and maintain the electrical components 12. For details, please refer to Figure 3 As shown, the window 111 faces the part of the electrical component 12 that needs to be connected or observed; Figure 3 In [reference figure], the power interface of the electrical component 12 located above faces the window 111, and the power supply can be conveniently connected by opening the shielding plate; Figure 3 In [reference figure], the wiring part of the electrical component 12 located below faces the window 111, and the wiring status can be directly observed by opening the shielding plate; During maintenance, it is not necessary to completely disassemble the maintenance board 11, which greatly improves the maintenance efficiency and reduces the downtime.

The upper outer edge part 1122A and the lower outer edge part 1122B are oppositely arranged on both sides of the cover-shaped part 1121. The upper outer edge part 1122A is detachably connected to the maintenance board 11, and the lower outer edge part 1122B is rotatably connected to the maintenance board 11. In this way, when the connection between the upper outer edge part 1122A and the maintenance board 11 is disconnected, the lower outer edge part 1122B rotates naturally, and the electrical components are in an exposed state, facilitating direct use by the user.

[0048] More preferably, the outer edge part 1122 includes: an upper outer edge part 1122A and a lower outer edge part 1122B. The upper outer edge part 1122A and the lower outer edge part 1122B are oppositely arranged on both sides of the cover-shaped part 1121. The upper outer edge part 1122A is rotatably connected to the maintenance board 11, and the lower outer edge part 1122B is detachably connected to the maintenance board 11. In this way, when the connection between the lower outer edge part 1122B and the maintenance board 11 is disconnected, the shielding plate 112 still covers the window 111, realizing flexible ventilation control. The shielding plate 112 can be opened or closed as needed, thereby flexibly controlling the degree of air flow entering the electrical compartment 1, which helps to maintain an appropriate temperature and ventilation environment for the electrical components 12 during maintenance.

[0049] Specifically, in a preferred embodiment, the rotatable connection method between the outer edge part 1122 and the maintenance board 11 is a hinge connection; In another preferred embodiment, the rotatable connection method between the outer edge part 1122 and the maintenance board 11 is a hinge 1122C connection.

[0050] More specifically, referring to Figure 4 , the upper outer edge portion 1122A is in a strip shape so as to be connected to the maintenance board 11 through a hinge 1122C.

[0052] More specifically, referring to Figure 4 , openings are provided on the lower outer edge portion 1122B so as to be connected to the maintenance board 11 through non-loosening screws 1122D.

[0053] Furthermore, the number of the grooves 13 is multiple, and the number of the maintenance boards 11 matches the number of the grooves 13; they can be classified and arranged in different grooves 13 according to the types of the electrical components 12 in the electrical appliance bin 1, and the electrical components 12 in other grooves 13 will not be affected during the process of maintaining and using the electrical components in one of the grooves 13; as Figure 3 shown, two upper and lower grooves 13 are shown, which are divided into a power connection part and a wiring part, improving the space utilization efficiency and facilitating the installation and maintenance of the equipment.

[0054] As Figure 5 shown, a wire outlet hole Y1 is further provided on the acting surface Y. Furthermore, a wire protection sleeve Y2 is provided on the wire outlet hole Y1. The wire outlet hole Y1 communicates the space outside the acting surface Y and the space inside the electrical appliance bin 1, making the linear connection more convenient and enabling the wires to be quickly connected; the setting of the wire protection sleeve Y2 can also effectively prevent the wires from being worn and damaged during use, extend the service life of the equipment, and at the same time play a dust-proof and waterproof function.

[0055] Furthermore, the unit components 2 include one or more of a high-voltage box 22, a PCS 21, a battery PACK, and a liquid cooling unit; Figure 5 An embodiment in which the high-voltage box 22, the PCS 21, and the electrical appliance bin 1 are in the same bin body is shown, improving the system integration degree. Integrating multiple components together makes the overall structure more compact, reduces the complexity of wiring and connection, and improves the reliability of the system.

[0056] Combining multiple components according to requirements improves flexibility and scalability. Flexibly selecting different component combinations according to actual requirements enables the unit to adapt to different usage scenarios and load requirements.
