Description

Technical Field

[0001] This invention belongs to the field of energy storage power station technology, and particularly relates to a duct structure for containerized energy storage power stations. Background Technology

[0002] Containerized energy storage power stations are integrated energy storage devices that combine core energy storage equipment such as battery clusters, battery management systems, energy storage converters, monitoring systems, and fire protection systems within a standard container. They can store electrical energy through energy storage cells and are widely used in grid-side, user-side, and new energy power station scenarios. The internal cooling system of a containerized energy storage power station typically includes an air duct structure. Currently, the air duct structure of existing containerized energy storage power stations includes air duct components, including outlet air ducts and connecting air ducts. The outlet air duct is strip-shaped and arranged horizontally, with an air inlet at one end along its length and a closed end along its length. The air inlet and outlet are connected by connecting air ducts. The outlet air duct has a bottom plate facing the central air conditioning unit and a top plate facing away from the central air conditioning unit. The outlet of this existing air duct structure is fixed, so it can only cool the entire system and is not convenient for enhancing the cooling of the hotter parts of the energy storage equipment. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a duct structure for a containerized energy storage power station, which can monitor the temperature of the energy storage battery pack and adjust the position of the air outlet, thereby enhancing the cooling of the areas of the energy storage battery pack with higher temperatures while simultaneously cooling the overall pack.

[0022] The present invention will now be described in detail with reference to the accompanying drawings. As shown in Figure 1, a duct structure for a containerized energy storage power station includes a main duct 1. First branch ducts 11 are sealed and fixedly installed at the air outlets on both sides of the main duct 1. Second branch ducts 12 are sealed and fixedly installed at the air outlets sequentially opened at the lower part of each first branch duct 11. Air outlets 13 are opened from top to bottom on the inner side of each second branch duct 12. A back plate 14 is fixedly installed between two adjacent second branch ducts 12. A housing 15 is fixedly installed on the inner side of each first branch duct 11. A base plate 16 is fixedly installed at the lower part of the second branch duct 12. Each housing 15 is connected to a transmission rod assembly 2. The transmission rod assembly 2 is connected to a movable air outlet pipe assembly 3.

[0023] In this implementation plan, in conjunction with the appendix Figure 2As shown, the transmission rod assembly 2 includes a motor 21. A rotating shaft 22 is fixedly installed at the output shaft of the motor 21. A driving bevel gear 23 is fixedly installed on the outside of the rotating shaft 22 in sequence.

The lifting plate 31 is moved by the transmission rod assembly 2, causing the infrared temperature sensor 33 to rise and fall. When the infrared temperature sensor 33 detects that the temperature of a certain area of ​​the energy storage battery pack is high, the motor 21 stops rotating, allowing cold air to be blown out from the connecting pipe 35 and the air outlet duct 32 to cool the energy storage battery pack and improve the cooling effect.

The bearing seat 25 supports the rotating shaft 22. When the lead screw 26 rotates, it can drive the lifting frame 27 to move linearly up and down, thereby driving the lifting plate 31 to rise and fall.

[0030] In this embodiment, specifically, the lower end of the lead screw 26 is mounted on the bearing of the base plate 16.
