A titanium sub-oxide/ruthenium oxide composite electrode and a preparation method and application thereof. Titanium-based titanium sub-oxide nanotubes is taken as a bottom layer, and titanium sub-oxide doped ruthenium oxide is taken as a surface composite active layer. A titanium substrate is anodized in a fluorine-containing ionic electrolyte, taken out, subjected to heating and roasting, cooled and then subjected to cathodic electrochemical reduction in polarizing liquid, so that a titanium-based titanium sub-oxide nanotube electrode is obtained; and then the titanium-based titanium sub-oxide nanotube electrode is taken as a cathode to be electrodeposited in a ruthenium trichloride electrolyte doped with titanium sub-oxide powder, taken out and then subjected to heating and roasting, so that the titanium sub-oxide/ruthenium oxide composite electrode is obtained.

Titanium sub-oxide/ruthenium oxide composite electrode and preparation method and application thereof

A blade device for a mixing propeller has a rocking shaft and a plurality of blade units. The blade unit is made of a flexible material and is installed on the rocking shaft via a fixing groove. The blade unit includes a horizontal propelling flexible blade and a vertical uplifting flexible blade. The fixing groove has a horizontal section and a vertical section. One end of the horizontal propelling flexible blade is inserted in the vertical section of the fixing groove while the other end of which is kept free so that it can swing back and forth. One end of the vertical uplifting flexible blade is inserted in the horizontal section of the fixing groove while the other end of which is kept free so that it can swing back and forth.
