The invention relates to a wave energy power generating device and belongs to the field of power generating devices. The wave energy power generating device comprises a water-turbine generator set and one or more wave energy water pumping assemblies; each wave energy water pumping assembly comprises a high pressure air buffering water storing chamber and a plurality of water pumps, wherein the water pumps are used for injecting seawater into the high pressure air buffering water storing chamber in one direction after the seawater is pressurized; the high pressure air buffering water storing chamber comprises a water storing chamber body, and the water storing chamber body is installed in the sea, a cavity is formed in the water storing chamber body, the cavity communicates with the water-turbine generator set through a pipeline; and all the water pumps communicate with the cavity through the pipelines provided with one-way valves. According to the wave energy power generating device, unstable wave energy can be transformed into electric energy, by adoption of the mode that water is pumped dispersedly and then centralized to push the water-turbine generator set for power generation, the wave energy water pumping assemblies become main investment parts of the power generating device, the wave energy water pumping assemblies do not include electric appliance equipment, and manufacturing cost is low, so that the ratio of output to input of the power generating device is high, and the wave energy power generating device is economically practical.

The invention discloses a temperature-controlled liquid swellable rubber, which contains (by weight), polyether glycol 30 to 60 percent, toluene diisocyanate 5 to 40 percent, unsaturated resin 2 to 30 percent, phenol-formaldehyde resin 2 to 30 percent, natural rubber 2 to 20 percent, catalyst 0.01 to 3 percent, reaction temperature controlling agent 5 to 40 percent, solvent 2 to 30 percent, plasticizer 2 to 10 percent, thermal stabilizer 0.5 to 2 percent, and foam regulator 0.5 to 2 percent. The preparation method comprises the following steps: adding polyether glycol into a reaction kettle at the weight percentage of 30 to 60 percent, heating to 120 DEG C, dehydrating for 30 min, cooling to 45 DEG C, adding toluene diisocyanate 5 to 40 percent, heating to 80 DEG C to 95 DEG C, keeping the temperature for 1.5 to 4 hr, cooling to 45 DEG C, adding the solvent 2 to 30 percent, adding reaction temperature controlling agent 5 to 40 percent and catalyst 0.01 to 3 percent into the reaction kettle, heating to a reaction control temperature 60 to 95 DEG C, keeping the temperature for 4 to 8hr, cooling to 45 DEG C, adding the plasticizer 2 to 10 percent, unsaturated resin 2 to 30 percent, phenol-formaldehyde resin 2 to 30 percent, natural rubber 2 to 20 percent, thermal stabilizer 0.5 to 2 percent, and foam regulator 0.5 to 2 percent, stirring for 0.5 to 1 hr, discharging, and packagingto obtain the product.

The invention discloses a high-yield strain of fusidic acid, a breeding method and application thereof. The name of the fusidic acid high-yielding strain is Fusidium coccineum NJWW-0520 (Fusidium coccineum NJWW-0520), and it is preserved in the General Microorganism Center of the China Committee for the Collection of Microorganisms, and the preservation date is March 21, 2018. The deposit number is CGMCC No.15473. In the present invention, long-term continuous use of DMSO (dimethyl sulfoxide) is used for stress-oriented domestication of fusidic acid-producing strains, and the high-yield fusidic acid strains are selected and bred. The yield of fusidic acid fermented by the domesticated strain is as high as 4932 μg / ml, which is 53.88% higher than that of the starting strain (3205 μg / ml), and has been fully applied in the production of efficient production of fusidic acid by the actual biological method.
