This invention relates to the field of fiber optic sensing technology, specifically to an NHCPCF fiber optic seawater salinity sensor with dual microchannels, its fabrication method, and its application. The sensor comprises: an introductory single-mode fiber, a nodeless hollow-core photonic crystal fiber, and an outtroductory single-mode fiber, sequentially fused together. The nodeless hollow-core photonic crystal fiber includes a first cladding and a main vent. Uniformly distributed silica tubes are disposed inside the main vent, with the tube wall tangent to the inner wall of the main vent and the axis of the main vent parallel to the axis of the silica tubes. The sensor utilizes the anti-resonance reflection waveguide principle of NHCPCF and specific microchannels to measure seawater salinity. It avoids the traditional method of large-area cavitation in the cladding, employing microchannels to improve integration, effectively prevent fiber breakage, and enhance mechanical strength during testing. This sensor exhibits high sensitivity (salinity sensitivity -0.88 nm / ‰), good repeatability, and stability.

The utility model discloses putty powder mixing equipment, including the shell, the upper portion welding of shell has the installation cover, water tank and filter box, the upper portion of shell and installation cover are penetrated with the shaft pipe through bearing, the inside of shell is equipped with the storage tray through bearing, the inside fixed insertion of storage tray is inserted to the lower extreme of shaft pipe, the lower portion of storage tray is equipped with the mounting shaft, the lower portion fixed penetration of shell has the hopper. Advantageous effects: the utility model is provided with installation cover, shaft pipe and storage tray, through the combination of shaft pipe, storage tray and pressure spray head, utilize the double mode of liquid mixing and high pressure air purging, realize the clearance of mixed space inner wall putty powder, compared with traditional brush plate contact type scraping, this kind of non - contact cleaning mode avoids the friction loss of scraper and inner wall, not only prolongs the service life of equipment key components, also reduces maintenance cost and downtime, guarantees the continuity and stability of putty powder mixing operation.
