This utility model discloses an L-shaped flood control wall structure, relating to the field of flood control wall technology. The utility model includes a main frame mechanism, which includes a first flood control plate. A second flood control plate is rotatably connected to the back of the first flood control plate via a pin. The utility model employs an unfolding assembly. Specifically, pulling or twisting causes a limiting rod to disengage from the limiting hole. Simultaneously, when the limiting rod moves, it causes the limiting plate to compress a third spring. The third spring, constrained by the inner wall of the second supporting sleeve, contracts and stores force. When the limiting rod disengages from the limiting hole, both the second and first springs generate a certain rebound force, causing the connecting rod and slider to reset. At this point, the second and first flood control plates are at a 90-degree angle. The equipment can be quickly unfolded to promptly block floodwater, buying valuable time for subsequent rescue work and minimizing casualties and property damage. Furthermore, it is foldable for storage, occupying little space and facilitating transportation and storage.

The present application belongs to the technical field of geological disaster monitoring, and discloses a debris flow velocity inversion method based on an optical flow model, and proposes an integrated optical flow framework for simultaneously inverting the surface velocity field and the front velocity of the debris flow. Through three sets of large-scale flume experiments, the method provides a robust and accurate tool for characterizing complex flow kinematics. By simultaneously measuring the surface velocity field and the front velocity, the main limitations of existing computer vision techniques are overcome, and a more comprehensive understanding of the flow process is achieved. The core scientific contribution lies in the new physical insights obtained through synchronous measurement: the research results provide direct and strong observational evidence, which links the high-frequency velocity pulses at the front to the secondary surge dynamics propagating from the tail. This discovery is crucial for understanding internal momentum transfer and energy dissipation. At the methodological level, the framework is superior to the benchmark deep learning tracker in terms of reproducing flow velocity statistical characteristics and ensuring numerical accuracy.
