This utility model relates to the field of oral motor training technology, specifically an air-blowing oral motor training device, including an air outlet flat tube, a connecting curved tube, and a mouthpiece. The air outlet flat tube has an internal cavity and an external cavity, which are connected by multiple connecting flat tubes. A sealing baffle is slidably connected inside the connecting flat tube. The air outlet flat tube is equipped with a driving component for driving the sealing baffle to close the connecting flat tube. By setting the driving component, the user can flexibly pull the sliding connecting plate to drive the sealing baffle to slide inside the connecting flat tube according to their own training needs, thereby achieving partial blocking or opening of the connecting flat tube, accurately adjusting the number of gas flow channels, and thus effectively adjusting the blowing resistance. The locking slider in the limiting component cooperates with the locking groove. After the resistance is adjusted, the return spring drives the locking slider to insert into the locking groove, stably fixing the position of the sliding connecting plate, ensuring that the resistance setting is stable and reliable during training.

This invention discloses a method for producing planting soil for landscaping using nitrogen- and phosphorus-polluted river and lake sediment. The method includes the following steps: collecting nitrogen- and phosphorus-polluted river and lake sediment; filtering the sediment through a separation unit to obtain a first mixed soil; allowing the first mixed soil to stand for one hour; adding auxiliary materials to the first mixed soil; and then subjecting it to intensive mixing through a mixing unit to obtain a second mixed soil; sending the second mixed soil to a ventilation chamber and adding a microbial compound inoculant to promote rapid decomposition, thus obtaining planting soil suitable for landscaping. This invention has the following advantages and effects: it designs a complete and standardized processing chain to improve nitrogen- and phosphorus-polluted river and lake sediment, producing planting soil for landscaping, turning waste into treasure, and realizing the resource reuse of sediment.

This invention discloses a method, apparatus, electronic device, and storage medium for power grid knowledge reasoning. The method includes: adjusting elements within a preset knowledge graph based on a neighborhood threshold distance and preset clustering rules; determining a power grid knowledge reasoning model based on the adjusted preset knowledge graph; and determining the knowledge reasoning result based on the power grid knowledge reasoning model and a distributed computing platform. This invention addresses the problem of missing attributes and relationships in knowledge graphs, enhancing the completeness of knowledge graph data. Furthermore, by enhancing the scalability of knowledge graph applications through a distributed platform, it addresses the contradiction between the openness and closedness of the knowledge graph's environment, improving the accuracy and reliability of the knowledge graph.

This utility model discloses a fire blanket and a fire-fighting device. The fire blanket includes a blanket body with a pressure relief port extending through it. A pressure relief mechanism is located at the pressure relief port and is movable relative to it to close or open the port. This fire blanket design prevents the accumulation of high air pressure within its coverage area during firefighting, thus preventing secondary accidents such as explosions caused by high-pressure smoke. It also effectively extends the time the fire blanket is in contact with the affected object, preventing the accident from spreading and providing more rescue time.
