The invention discloses a method for synchronous precipitation and polymeric synthesis of floatable silver sulfide nanocrystalline, relates to a preparation method of the silver sulfide, and solves the problems that a surfactant is needed to be added so as to increase the cost and the prepared silver sulfide has large grain diameter and easily sinks to the bottom in water in the conventional microemulsion method. The method comprises the following steps of: 1, preparing solution of silver nitrate ethanol; 2, adding toluene into the silver nitrate ethanol, and dripping 3-mercaptotrimethoxy silane, and stirring to obtain sol; 3, performing hydrothermal synthesis; 4, distilling; 5, drying; and 6, roasting to obtain the floatable silver sulfide nanocrystalline. The floatable silver sulfide nanocrystalline is spherical particles, has the grain diameter of 2 to 20nm, and can float on the water surface. During preparation, the surfactant is not used, so that the cost is reduced; and the reaction condition is mild and easily controlled. The method can be applied to the fields of photocells, photocouductors, photocatalysts, IR detectors, and the like.

The invention relates to a floating-based ocean tide level forecasting electronic device, which includes a tide level monitor, a floating base and a stabilizing component. The tide level monitor is installed on the floating base through bolts, and the stabilizing component is installed on the lower end surface of the floating base. The present invention can solve the problems existing in the existing tide level monitoring device when monitoring the ocean tide level: a: when the existing tide level monitoring device is placed on the sea surface, the floating air bag often falls off, and the equipment sinks to the bottom; b: the existing tide level monitoring device When the tidal level monitoring device monitors the sea tide, it often happens that the equipment rolls over and sinks due to excessive wind and waves. The sinking of the equipment will lead to the loss of monitoring data, which will increase the monitoring cost and affect the normal monitoring work.

The invention provides an offshore solar illuminating and heating heat preservation bathroom. A foaming cement brick wall is enclosed on a buoyancy bottom plate; a double-inclined-plane or four-inclined-plane foaming cement house cover plate is arranged on the upper part of the foaming cement brick wall; a solar thermal collector is arranged on the outer side of the foaming cement brick wall on the sun facing side; a water inflow pipe is arranged in the solar thermal collector; the upper end of the water inflow pipe is communicated with a water storage tank which is arranged on the lower part of the foaming cement house cover plate; the lower part of the water storage tank is connected with a spray head through a pipeline; a solar cell panel is arranged on one surface of the foaming cement house cover plate on the sun facing side, and is connected with a storage cell arranged on the lower part of the foaming cement house cover plate through a guiding wire; and the storage cell is connected with light-emitting diode (LED) illuminating lamps arranged at the upper corners of an indoor wall surface through guiding wires. The offshore solar illuminating and heating heat preservation bathroom has the characteristics that the bathroom has floating performance and heat preservation performance and can be used for heating bath water and generating electricity for illumination through solar energy; and the bathroom is suitable to be used as a bathroom for baths in a bathing beach.

The invention relates to a built-in buoy towing barrel-shaped foundation sinking method, wherein a barrel-shaped foundation is divided into four cabins with fan-shaped sections through a compartment, a buoy is arranged inside the barrel-shaped foundation and comprises four branch buoys which are matched with the cabins of the barrel-shaped foundation, and a vibration isolating cushion is arrangedbetween the branch buoys and the barrel-shaped foundation; after the barrel-shaped foundation is towed in place, exhaust valves and drain valves arranged on the built-in branch buoys are opened, air in the branch buoys is pumped to the inside of the barrel-shaped foundation, the branch buoys can slowly retreat from the barrel-shaped foundation and sinks to the water bottom, then the barrel-shapedfoundation is towed to an accurate sinking position, and a discharge control valve at the top of the barrel-shaped foundation is opened to discharge gas and water to finish the sinking operation of the barrel-shaped foundation. The invention has the advantages that the buoy can be conveniently reclaimed through replacing the gas in the built-in buoy to the inside of the barrel-shaped foundation, and meanwhile, the barrel-shaped foundation has floating stability, sinking in place is ensured to be safely and effectively carried out, and the method has convenient construction, is simple and has remarkable cost advantage.

The present invention discloses a strain of Bacillus subtilis XDK06, which has been deposited in the Guangdong Provincial Microbial Culture Collection Center on October 30, 2020, and the preservation number is GDMCC No: 61260; the present invention also discloses the strain of the Bacillus subtilis XDK06. Cultivation method and use thereof in organic fertilizer fermentation. The Bacillus subtilis XDK06 has anaerobic fermentation properties, and can ferment organic materials under anaerobic conditions without aeration. It needs to turn the heap 1 or 2 times, which greatly reduces the labor intensity, can fully decompose the organic materials, and retain the nutrients in it to a greater extent. , which can gradually release nutrients and improve the effective utilization of fertilizers.

The invention discloses a symmetrical semi-shading type tidal current energy generation device. The generation device is composed of a semi-shading device, a generation device body and telescopic pile legs. A current guide part of the semi-shading device is provided with a special shaped line design. The whole device is fixed to the seabed through the telescopic pile legs after sinking to the appropriate depth. The upper portion of the semi-shading device is provided with a cuboid-shaped motor protective cover. A change speed gear box and a generator are arranged inside the protective cover. The generation device body comprises vertical axis water turbines comprising flap type composite blades, the change speed gear box and a generator set, wherein the axis centers of the flap type vertical axis water turbines are arranged into a line on a straight line, and one bilateral type semi-shading device is installed between every two flap type vertical axis water turbines. Through two vertical impellers and the symmetrical distribution of shading current guide shells of the two vertical impellers, the conflux effect is strengthened, and the utilization ratio of tidal current energy is improved. Modularized manufacturing and lateral spreading are facilitated through the symmetrical semi-shading type tidal current energy generation device, therefore, the generation device can be installed and applied in a wide water area in an array mode, and accordingly large-scale power generating through the tidal current energy is achieved.
