The utility model discloses a modularization Y type anti -suction belt liquid baffle structure and full -liquid evaporator. The baffle structure includes two -stage Y type baffle array, baffle fender and convex type clamping groove, two -stage baffle misplacement arrangement, interval 3 4mm, vertical interval 0.25mm, are fixed through fender Y type groove, and the modularization installation is realized to bottom convex type clamping groove and evaporator inner wall groove clamping groove cooperation. Its two -stage separation mechanism can high -efficiently intercept the liquid refrigerant in gas -liquid mixture, and separation efficiency is greater than or equal to 95%, and flow resistance is less than or equal to 50Pa. Full -liquid evaporator sets this baffle structure below compressor suction port, is fixed through clamping groove, significantly reduces the risk of liquid knock, and installation and maintenance are convenient, adapts to different pipe diameter evaporator, and is applicable to the safe and efficient operation scene of refrigeration system.

This invention relates to the preparation and electrocatalytic application of molybdenum-nickel telluride based on NiO self-sacrificial template in the field of hydrogen evolution electrocatalysis. The purpose of this invention is to solve the problems of high cost of noble metal hydrogen evolution catalysts, slow kinetics of alkaline hydrogen evolution reactions, insufficient active sites in single-phase telluride, and limited electron transport and interfacial synergistic effects in existing technologies. This patent designs and develops a molybdenum-nickel telluride composite material MoTe2 / NiTe2 based on NiO self-sacrificial template. The method used: using the polyacid precursor SiMo... 12 Using NaTeO3 as raw material, NiO as a self-sacrificing template and nickel foam conductive substrate, a molybdenum-nickel telluride composite catalyst was prepared by hydrothermal synthesis. This catalyst is suitable for electrocatalytic hydrogen evolution reaction in alkaline electrolyte and has high catalytic activity, good conductivity, abundant heterostructures and excellent long-term stability.

This utility model discloses a basket structure for maritime rescue, relating to the field of maritime rescue technology. The utility model includes a first connecting block and a second connecting block disposed above the first connecting block. A first connecting rope is fixedly connected to the top of the second connecting block. It also includes: an extension portion disposed above the first connecting rope; a retractable portion disposed on the first connecting block; and several retractable portions, all located outside the first connecting block. Each retractable portion includes several support assemblies. This utility model, by incorporating the retractable portion, solves the problem of existing basket structures being inconvenient to retract during use. This results in a large surface area of ​​the basket's bottom in contact with the water when lowered into the water, causing the buoyancy of the water to act instantly over a large area, leading to violent shaking of the basket and hindering rescue efforts.
