Currently, large-scale planting of submerged plants through planting trays has become the mainstream technical means for ecological restoration. Traditional planting trays mostly adopt an integral structure, which is difficult to flexibly adjust according to the lake topography, water depth, and bottom sediment conditions. Moreover, they suffer from low efficiency in transportation, installation, and subsequent maintenance. As ecological restoration projects develop towards "modularization, intelligence, and sustainability," how to achieve efficient assembly and environmental adaptation through innovative tray structures has become a key research direction for improving the effectiveness of lake restoration.

The connection methods between bases mostly involve welding, snap-fitting, or simple binding, which result in insufficient connection strength and poor disassembly, leading to high operation and maintenance costs for restoration projects.

[0004] To address the aforementioned issues, there is an urgent need to develop a modular submerged plant planting base with high adaptability and ease of maintenance. By innovatively designing the connection components of the threaded cylinder and screw, the base frame can be quickly assembled and disassembled, breaking through the limitations of the traditional integral structure.
