Aiming at insufficient drying seafood on-board caused by hull swings, the present invention involves the establishment of location correction system for processing seafood transportation displaced by wind waves and anti-accumulation drying processing method. This invention employs CFD-DEM method to simulate the state and distribution of the material particles modulated by the deflector angle and wind speed. Finally, the optimized rotation angle of deflector and wind speed are obtained where material particles are equally distributed. Meanwhile, the uniform and fast drying of the marine products in the swinging hull are achieved. This invention shows the great advantages of high efficiency, automation and continuity.

A method of upgrading encryption machine, including: a controller for managing upgrading of encryption machine determines a first encryption machine to be upgraded; the controller transfers the data of the first encryption machine to a second encryption machine; and the controller sends an upgrade command for instructing the first encryption machine to conduct the upgrade to the first encryption machine. The above method solves the problem that in the process of upgrading the encryption machine in the conventional techniques, the operation is extremely complicated, which is easy to cause an operation error and interruption of user service.

The present invention provides an anti-fouling and anti-corrosion agent for the marine steel structure surface and preparation method thereof. The emulsion is made of raw materials at the following mass ratios: 1100 to 1500 parts of a polyurethane monomer, 1000 parts of polyether glycol, 200 to 400 parts of an alcohol chain extender, 100 to 250 parts of a hydrophilic chain extender, 200 to 400 parts of epoxy resin polyols, 100 to 150 parts of triethylamine, 400 to 1000 parts of an acrylate monomer, 1000 to 1500 parts of a graphene oxide-protamine composite emulsion, and 5 to 20 parts of an initiator. The solvent-free and composite film-forming resin emulsion of the present invention has both anti-fouling and anti-corrosion functions, which applies to a production of a green and environmental marine coating and protects the marine steel structure surface to prevent from organism attachment and sea water corrosion.

A continuous trawl fishing method includes: by dragging a fishing net in water through a vessel, carrying out trawling operation so that catches to be fished enter a cod-end of a fishing net tail; then tractioning and moving the cod-end so that a sucking fish tube of a vacuum sucking fish pump reaches into the cod-end; and a tube mouth of the sucking fish tube contacting the catches in the cod-end to run the vacuum sucking fish pump to suck the catches from the cod-end into the collection tank through the sucking fish tube, and the catches in the collection tank being then transferred and frozen or directly processed. The fished catches of the present invention are obviously improved in indicators such as the stiffness time and the number of the first-grade fresh fish and so on. The histamine content is obviously reduced and the catch quality is improved.
