Description

Technical Field

[0001] This utility model relates to the field of energy storage battery technology, and in particular to a battery tilt rack for energy storage power stations. Background Technology

[0002] Currently, energy storage power stations that use batteries as the energy storage medium generally install several thousand individual battery cells on a battery rack. In order to save space, large-scale energy storage power stations also need to stack the entire battery rack and the batteries on it as a single energy storage unit. However, tubular lead-acid batteries have the following characteristics: they can withstand high current surges, are suitable for high current discharge applications, have long charge-discharge cycle life, low self-discharge, high depth of discharge, and long service life. However, their large size and weight make them inconvenient to carry, and their high natural discharge rate makes them easy to be damaged if not charged for a long time. Yet, they are very suitable for the application scenarios of battery energy storage power stations.

[0003] However, the existing tubular lead-acid batteries generally have long, rectangular cylindrical casings. After being installed on battery racks and stacked in multiple layers, the entire energy storage battery assembly becomes very tall. Maintenance aisles need to be left on both sides of the battery assembly, wasting space that could have accommodated more batteries. When installing or maintaining the upper batteries, personnel need to reach the top of the top battery to access the upper battery terminals, making wiring or other operations extremely inconvenient and unsafe. Furthermore, the existing long, box-shaped batteries have small individual plates, resulting in low energy density. Therefore, the best solution is to lay the long, cylindrical tubular batteries with large plates to one side. This would ensure energy storage efficiency while reducing the space occupied by maintenance aisles, effectively saving space, making wiring easier for personnel, and increasing space utilization.

[0004] However, during the charging and discharging of tubular lead-acid batteries, heat is generated inside the battery. The electrolyte inside the battery expands due to heat during charging and discharging and needs to be vented. The venting safety valve of existing tubular lead-acid batteries is generally located on the acid filling hole on the top cover of the battery. After the battery is filled with acid, the venting safety valve is closed to complete the seal. If the battery is laid horizontally after filling with acid, the flowing battery fluid inside the battery will block the venting safety valve, causing safety problems. Moreover, the seal of the battery cover is also easily corroded and damaged by the battery fluid inside the battery, leading to battery failure. Summary of the Invention

[0005] This invention proposes a tilted battery rack for energy storage power stations, which facilitates the tilting and horizontal placement of tubular lead-acid energy storage batteries. This effectively improves the space utilization rate of energy storage power stations and the convenience of maintenance and installation personnel, while avoiding battery failure caused by battery fluid clogging the venting safety valve or corroding the sealing structure of the battery cover.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A battery inclined rack for an energy storage power station is characterized by including a battery rack body and a number of inclined platforms corresponding to the batteries; the battery rack body is a rectangular frame, wherein at least one layer of mounting platform is provided, and the inclined platforms are detachably and fixedly mounted on the mounting platform.

[0008] The inclined platform is a wedge-shaped block. The upper surface of the inclined platform is a sloped surface at a certain angle to the horizontal plane. The upper surface of the inclined platform has upward protruding rims on both sides of the extension direction and on the lower end side, which are used to position the tubular battery when it is placed obliquely on the upper surface of the inclined platform and prevent it from sliding with the sloped surface.

[0009] A further solution is to increase the stability of battery installation, increase the friction of the battery placed at an angle on the inclined platform, and reduce the weight of the battery borne by the lower side of the inclined platform. The upper surface of the inclined platform in contact with the battery is also provided with a rubber pad.

[0010] A further solution is to set the position of the sealing structure in the battery cover of different heights and sizes, and the angle between the inclined surface of the inclined platform and the horizontal plane is 15°-25°.

[0011] The beneficial effects of this utility model are: it provides a tilted battery rack for energy storage power stations that facilitates the tilting and horizontal placement of tubular lead-acid energy storage batteries, which can effectively improve the space utilization rate of energy storage power stations and the convenience of maintenance and installation personnel, avoid battery failure caused by battery fluid clogging the exhaust safety valve or corroding the sealing structure of the battery cover, and has a simple structure that is easy to modify in existing energy storage power stations, and has promotion and application value.
