This invention discloses a drilling device for processing and producing wrought iron railings, relating to the field of wrought iron railing processing technology. It includes a support leg, a drilling mechanism, and a fourth transmission rail. The drilling mechanism is located on the top of the support leg, and the fourth transmission rail is installed on the top of the support leg. The drilling mechanism includes multiple positioning frames that slide on the top of the fourth transmission rail. Each positioning frame has a railing placement groove on its top to ensure the holes are at the same horizontal position. After drilling, the railings are directly welded and fixed, ensuring that the holes of the connecting pieces align with the connecting posts during subsequent bolt connections. This improves installation quality and avoids enlarged holes and misalignment of the railings after installation. This process ensures that the holes of the connecting pieces and connecting posts correspond perfectly, improving hole accuracy. Direct welding after drilling reduces process steps, increases processing efficiency, and ensures overall structural dimensional stability.

This invention discloses a training method and apparatus for a 3D meandering river recognition model, and a method for identifying meandering rivers. The method includes: acquiring several interpretation results and corresponding seismic data volumes in a target area; initializing a preset label data volume based on the interpretation results and the seismic data volume; masking the label data volume to update it; inputting each seismic data point in the seismic data volume as sample data into a pre-constructed image segmentation model for training; calculating a loss function value based on the output of the image segmentation model and the updated label data volume; adjusting the parameters of the image segmentation model inversely based on the loss function value; iteratively training until the loss function reaches a preset convergence condition, stopping the training, and obtaining a trained 3D meandering river recognition model. This model enables the identification of meandering rivers in a target area using sparse labels, improving the efficiency of seismic data interpretation.
