The utility model discloses an iron nail polishing machine relates to iron nail polishing technical field, the utility model discloses a position switching drive assembly drives double board mounting assembly rotation, makes sealing plate and sieving plate side surface of sticking cylinder slide, make sealing plate or sieving plate cover import and export or make import and export completely expose, when import and export are located downside and are covered by sieving plate, the powder of auxiliary material and iron nail scrap produced in polishing process can pass through sieving plate and fall in the powder box, realize the quick filtration to auxiliary material, save time and effort, when import and export are located upside and completely expose, through the cooperation of front and back movement subassembly, electric telescopic pole and electromagnet, the iron nail after polishing in cylinder interior is adsorbed on the surface of electromagnet and shifts to the iron nail box, can separate the iron nail after polishing with the polishing auxiliary material quickly, make the polishing auxiliary material after filtration be retained in cylinder for subsequent polishing use, realize the quick filtration and continuous use to polishing auxiliary material.

A river ecological dike dam comprises a bottom frame body, a storage shell is arranged on the bottom frame body, and the upper surface of the storage shell is obliquely arranged; the storage shell comprises bottom supporting rods connected with the bottom frame body, a plurality of vertical supporting rods are arranged on the bottom supporting rods, a bottom supporting net is arranged between every two adjacent bottom supporting rods, and a vertical supporting net is arranged between every two adjacent vertical supporting rods. Lateral supporting nets are arranged between the bottom supporting rods and the vertical supporting rods which are oppositely arranged, and gaps among the bottom supporting nets, the vertical supporting nets and the lateral supporting nets are filled with coarse sand. According to the device, the mode that the device is arranged at the bottom of the dike dam is adopted, the collecting and filtering effects on shoreside sundries and garbage can be achieved, water and soil loss can be prevented, and under some conditions needing greening, some plants suitable for the conditions can be planted by internally arranging coarse sand so as to meet the greening requirement.

This utility model discloses a negative pressure filter connector, comprising: a stopper head, facing each other, for connecting glassware of different specifications; a flow guide tube, inserted inside the stopper head, for transferring samples from the glassware; and a filter layer provided on one and / or both sides of the stopper head. In this utility model, the trapezoidal stoppers facing each other fit tightly against the mouths of glassware of different specifications, and the interference fit between the flow guide tube and the insertion hole forms a sealed flow channel. This allows for rapid connection, negative pressure sealing, sample transfer, and filtration purification of glassware of different specifications, effectively simplifying the cumbersome process of sealing adjustment and assembling the filter device in traditional operations.

This invention belongs to the field of data retrieval and discloses an efficient spatial dataset query method based on density grayscale images. It includes two stages: a data processing stage, which processes a given spatial database, constructs a global rectangular region, divides it into grids, and generates a density grayscale image for each spatial dataset based on the density distribution information of location points within the corresponding grid; and a query execution stage, which generates a sample grayscale image based on a given query sample dataset, compares the sample grayscale image with the grayscale images of each dataset, identifies overlapping candidate datasets, calculates the similarity between the candidate datasets and the query sample datasets based on the generated candidate dataset grayscale images and the sample grayscale images, and selects the k datasets with the highest similarity as the query results. This invention can effectively reduce the computational load and complexity of queries, providing more accurate and comprehensive query results, thereby balancing query accuracy and efficiency.
