Background Ultrapure water deionization equipment is one of the core components of modern industrial water treatment systems, and in practical applications, in order to meet the water yield requirement and save space, a plurality of standardized square EDI modules are usually installed in a single integral bracket in a side-by-side compact manner. However, this high density layout saves floor space, but exposes significant drawbacks of the prior art in terms of mechanical design and maintainability: 1. In order to pursue high-density layout, gaps between the modules and adjacent units and between the modules and the support structure are compressed to the limit, maintenance personnel have to perform clumsy drawing and installation operations in extremely narrow gaps by virtue of manpower, the heavy modules are difficult to stably move out and are extremely easy to collide with peripheral precision equipment, so that the fluid interface connectors of the modules and the adjacent units are subjected to irreversible physical damage, and extra maintenance gaps which are far larger than the physical size of the modules are reserved between the modules and the support side plates, so that tools such as screwdrivers, wrenches and the like can conveniently enter and be manually operated, but the extra maintenance gaps are in idle states in the operation time, are essentially passive space waste, seriously weaken the advantages brought by high-density layout, lead to huge whole support system and low space utilization efficiency; 2. When a new module is installed, maintenance personnel need to perform blind alignment and insertion on a plurality of precise water interfaces on the back of the heavy module and corresponding interfaces on a bracket motherboard under limited visual field and operation angle, the process requires extremely high alignment precision, but in actual operation, an effective guiding and fault-tolerant mechanism is lacked, and small angle or position deviation can lead to rigid collision of the interfaces, so that contact pins are bent, a sealing ring is sheared or a shell is scratched, and the installation process is low in efficiency.
