A ventilation cap of a gearbox relates to the technical field of gearboxes and comprises a plug body and a filter screen, an air inlet hole, a first condensation oil cavity, a second condensation oil cavity and an exhaust hole are formed in the plug body, and the air inlet hole, the first condensation oil cavity, the second condensation oil cavity and the exhaust hole are communicated in sequence; the filter screen is installed in the air inlet hole and used for filtering oil liquid in the oil-gas mixture entering the first condensation oil cavity from the air inlet hole. The oil-gas separation effect can be improved while the size is reduced, the oil recovery amount is increased, the operation cost is reduced, and disassembly and assembly in a limited space environment are facilitated.

The utility model discloses a water -saving photovoltaic module intelligence cleaning device, including the cleaning machine case, the inside of cleaning machine case is provided with water tank and cabin respectively, the inside of cabin is installed with first water pump and second water pump respectively, the water injection opening of second water pump is connected with water injection rod through pipeline, the water outlet of water injection rod is installed with the cleaning disc, the surface of water injection rod is fixed with the connecting assembly, the utility model discloses the recovery box, the water collecting plate, the connecting assembly and first water pump through the design, through the water washing cleaning of the wastewater that the photovoltaic module surface that is in the inclination installation generates along the inclination surface and flows, in the process of flowing, through the water collecting plate and concentrate collection, concentrate the wastewater and flow into the recovery box, first water pump work will be in the wastewater in the recovery box and send to the water cabin, realize water circulation use, reach water -saving effect.

The invention discloses an environment-friendly long-acting antifouling paint and a preparation method thereof, and belongs to the technical field of paint materials and antifouling. The environment-friendly long-acting antifouling paint comprises the following components in parts by weight: 30-50 parts of a component A, 25-45 parts of a component B, 8-25 parts of a functional body, 1-5 parts of color paste and 0.3-3 parts of an auxiliary agent, the component A is an aliphatic isocyanate prepolymer which is prepared from aliphatic isocyanate and castor oil through a reaction, and the specific preparation raw materials comprise the following components in parts by weight: 20-40 parts of aliphatic isocyanate and 10-20 parts of castor oil; the component B is polyaspartic acid ester, and the molecular weight of the polyaspartic acid ester is 800-1500 g / mol; the castor oil has good reaction activity with aliphatic isocyanate, can significantly improve the flexibility of a prepolymer (polyurea precursor) and the cohesiveness with a base material, and can optimize the compatibility of the polyurea precursor with polyaspartic acid ester with the molecular weight of 800-1500 g / mol, thereby improving the mechanical stability and weather resistance of the whole polyurea paint coating. The technical problem that an existing coating material cannot give consideration to synergistic improvement of environmental protection property and mechanical property is solved.
