Battery Cabinet Drain Valve Assembly for Bottom-Up Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing battery cabinet drain parts are difficult to assemble and disassemble, requiring complex steps and operation within the cabinet, which hinders convenience and increases the risk of damage to battery cells due to moisture accumulation.
Innovation Solution
A battery cabinet design featuring a drain valve assembly installed in the lower cabinet body with a butt joint to the upper cabinet's drain outlet, allowing for bottom-to-top installation and disassembly without moving battery cells, improving sealing performance and reducing internal space occupation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the drain valve assembly is installed from the inside of the battery cabinet using existing methods, then the drainage function is achieved, but the assembly and disassembly operations become complex and difficult
Solution Approach 1:
The patent inverts the traditional installation direction by installing the drain valve assembly from the bottom of the lower cabinet body upward, rather than from the inside of the upper cabinet body downward. This inversion allows workers to access the installation port from the bottom side, significantly simplifying the assembly and disassembly operations while reducing the need for complex internal maneuvers within the cabinet.
Solution Approach 2:
The patent changes the installation dimension by providing a drain valve installation port in the bottom of the lower cabinet body, allowing installation from a different spatial dimension (bottom-up) rather than the traditional internal approach. This dimensional change transforms the installation process from a complex internal operation to a simpler external operation accessible from the bottom side.
2Quantity of substance
If the drain valve assembly is installed in the upper cabinet body, then the drainage function is achieved, but the internal space of the upper cabinet body is occupied
Solution Approach 1:
The patent extracts the drain valve assembly from the upper cabinet body and relocates it to the lower cabinet body. By taking out the drain valve assembly from its traditional location in the upper cabinet body and installing it in the lower cabinet body instead, the patent eliminates the space occupation problem while maintaining the drainage function.
Solution Approach 2:
The patent resolves the space conflict by moving the drain valve assembly to a different spatial location (lower cabinet body bottom) rather than occupying space in the upper cabinet body. This dimensional relocation allows maximum utilization of the upper cabinet body for battery cell storage while the drain valve assembly occupies space in the lower cabinet body where it does not interfere with battery accommodation.
3Ease of operation
If the drain valve assembly is installed from the inside of the battery cabinet, then the drainage function is achieved, but battery cells need to be moved during disassembly
Solution Approach 1:
The patent inverts the installation approach by providing access to the drain valve assembly from the bottom of the lower cabinet body rather than from the inside of the upper cabinet body. This inversion allows disassembly without needing to move battery cells, as the installation port is accessible from the external bottom side.
Solution Approach 2:
The patent designs the lower cabinet body with a dedicated drain valve installation port in the bottom, preparing the structure in advance to allow easy access for assembly and disassembly operations. This preliminary structural arrangement eliminates the need for time-consuming battery cell relocation during maintenance operations.

AI summary
Provided are a battery cabinet including a cabinet body and a drain valve assembly. The bottom of the drain valve assembly is fixed, by an installation port at the bottom of the cabinet body, to the battery cabinet from bottom to top, and the top of the drain valve assembly is in butt joint with a drain outlet in the cabinet body. The drain valve assembly is provided with magnetic substances, which can realize automatic drainage. Compared with a method for installing a drain valve assembly from the inside of a battery cabinet in the prior art, the operation of fixing the drain valve assembly through the installation port in the present application is more convenient, the drain valve assembly can be disassembled without moving battery cells in the cabinet, and thus convenience of disassembly and assembly of the drain valve assembly is improved.
