This invention relates to a floating photocatalytic material, its preparation method, and its application in cyanobacteria control. The method includes the following steps: uniformly mixing a phenolic compound, an aldehyde solution, a solvent, and an alkaline catalyst, followed by a prepolymerization reaction to obtain a prepolymer; adding a foaming agent to the prepolymer and mixing uniformly to obtain an emulsion; adding an acidic catalyst to the emulsion and undergoing a gelation reaction to obtain a wet gel; and curing the wet gel by heating to obtain the floating photocatalytic material. This invention utilizes an integrated foaming process to simultaneously form a porous structure with interconnected internal components during synthesis, giving the material sufficient low density to achieve self-floating. The material itself is the photocatalytically active component, simultaneously possessing structural support and buoyancy functions, achieving integrated construction of material function and structure. This effectively avoids problems such as active component shedding, loss, and secondary pollution, resulting in high catalytic efficiency. This material can be directly used as a floating board for cyanobacteria control, achieving efficient and eco-friendly continuous inhibition of cyanobacteria.

The invention discloses an automobile anti-sinking floating device and a using method, the automobile anti-sinking floating device comprises a box body, a water immersion detection control module arranged in the box body, an anti-sinking folding air bag module, an ejection air taking flying probe module and an air conveying module used for supplying air to the anti-sinking folding air bag module, the immersion detection control module is used for detecting an automobile immersion signal and an immersion depth signal; when a water immersion signal and a water immersion depth signal exceed set values, the water immersion detection control module controls a gas taking flying needle in the ejection gas taking flying needle module to pierce into an automobile tire, gas is taken from the automobile tire, the gas is conveyed into the anti-sinking folding airbag module through the gas conveying module, and the anti-sinking folding airbag module is connected with the water immersion detection control module. And an anti-sinking air bag in the anti-sinking folding air bag module is inflated and opened. The anti-sinking floating device for the automobile adopts a pure mechanical structure, can not be influenced by various external factors, and can reliably realize the anti-sinking floating function of the automobile.
