The method comprises the following operation steps of (1) adding zinc nitrate hexahydrate and sodiummetavanadate into deionized water; adding a mixture into a stainless steel reaction kettle; performing reaction to obtain nanometer zinc vanadate; (2) adding N-isopropylacrylamide and trifluoroethyl acrylate into a reaction container; then, adding deionized water, emulsifiers, azodiisobutyronitrile, nanometer zinc vanadate and organic pigment powder into the container to obtain gel microspheres; (3) adding polyethylene masterbatch, antioxidants and inorganic filling materials into an extruding machine for extrusion reaction; adding the gel microspheres into a plasticization section of the extrusion machine; performing extrusion, granulation and cooling to obtain the master batch for the water conservancy project buoy. The water conservancy project buoy prepared by the master batch has theexcellent stain resistant performance, and cannot easily generate the water absorption weight increase and buoyancy reduction phenomena in the use process; the service life of the project buoy can beeffectively prolonged.

The invention discloses a booster installing and supporting structure with an assembling compensating function. A first supporting block, a second supporting block, a third supporting block and an elastic device are included. The interiors of the three supporting blocks are integrated and connected through slide rails; the first supporting block and the second supporting block are in bevel contact, and the second supporting block and the third supporting block are in horizontal plane contact. In use, the supporting structures are uniformly distributed in the peripheral direction and adhere tothe inner wall face of a combustion chamber. After a booster is pushed in, the first supporting block retracts in the circle center direction along the slide rail bevel so that the head of the boostercan be tightly held. When the supporting structure bears the radial load, due to friction self locking, the structure is in a stable tight holding state all the time. The remaining travel of a springcan compensate for the axial heat expansion of the booster. The booster installing and supporting structure with the assembling compensating function has the assembling compensating capacity and thethermal expansion compensating capacity, and when a liquid stamping engine plug-in type booster has a diameter deviation and also needs to meet the reloading requirement, the booster installing and supporting structure can serve as the installing and supporting structure of the booster.

The invention relates to a digital controlled light source drive device, which comprises a digital processor and a boosting loop. The digital processor comprises a digital switch signal generating module and a protection module; the digital switch signal generating module is used to generate at least a group of digital switching signals; the protection module is used to generate a group of protection switch signal. The boosting loop is connected to the protection module, and according to the protection switch signals, generates a power signal. After the digital processor generating the digital switching signals, the digital controlled light source drive device is turned into the protection switch signal through the protecting loop and input the boosting loop to ensure the boosting loop function well when generating the wrong digital switching signal.

The invention provides a manufacturing device and a manufacturing method of a raw material for forging processing. The manufacturing device of the present invention includes a chamfering device, which is installed near a cutting machine that cuts a bar-shaped raw material into a predetermined length to form a cut raw material, and uses a press that presses the faces of a pair of dies against the corners of both ends of the cut raw material.
