  • Patent number: 12221756
    Abstract: A self-acting dredging and drainage structure for a plain river network irrigation area is provided. The structure includes a first tube body, a water inlet end side of the first tube body is provided with a trash rack, a partition body is provided in the first tube body, and a water outlet end side of the first tube body is provided with a contraction and diversion device. The contraction and diversion device divides a water outlet end of the first tube body into an upper water outlet side and a lower water outlet side, and the contraction and diversion device includes no less than one arranged contraction and diversion pipe; and the upper water outlet side has first water outlets and second water outlets.

  • Patent number: 12211126
    Abstract: The application relates to a run-length stripping method for generating skeleton lines of complex plain river networks, including following steps: 1. constructing an empty raster field, each raster row generates an empty run-length linked list; 2. completing raster compression on each row, and compressing the continuous grids into run-length units and inserting them into the raster row run-length linked list; 3. establishing a raster field river boundary grid search template; 4. setting two discriminant functions to judge whether a grid on a raster field is a redundant grid; 5. searching all boundary grids along a raster field boundary, and marking and stripping all redundant grids based on two discriminant functions respectively; 6. analyzing whether the boundary grid is stripped, if so, returning to continue stripping, otherwise, entering the next step; 7. converting the non-stripped grid into skeleton line data in vector form.

  • Patent number: 12071207
    Abstract: An apparatus for determining an optimal route of a maritime ship includes a database configured to store a service speed of the maritime ship. The apparatus further includes a processor configured to generate a plurality of state nodes, to determine a plurality of time sets, to append the plurality of time sets to the plurality of state nodes to obtain a plurality of appended state nodes, to generate a plurality of edges based on the plurality of appended state nodes, to generate a graph based on the plurality of appended state nodes and the plurality of edges, to apply a preliminarily generated optimal route algorithm on the graph to obtain a preliminarily defined route path, and to apply a genetic algorithm based on the preliminarily defined route path to obtain the optimal route of the maritime ship.

  • Publication number: 20230405216
    Abstract: This application relates to the field of injection technology, especially a type of portable carbon dioxide gas injector. The technical solution of the invention includes a storage tube, one end of which is connected with a passage tube, and a passage valve is provided at the end of the passage tube away from the storage tube. A piston adapted to the injection device body is arranged inside the storage tube. A driving assembly for driving the piston is arranged on one side of the piston away from the passage tube, and a regulating assembly for adjusting the gas storage volume is arranged on the other side of the driving assembly away from the passage tube. The invention achieves quantitative control of the injection amount of carbon dioxide, which can alleviate the discomfort of patients.
