The present invention relates to the technical field of composite membranes, and discloses a PO composite membrane and a preparation method thereof. The PO composite membrane prepared by the present invention comprises a base membrane and a coating liquid; wherein the base membrane is formed by coextrusion of an inner layer, a secondary outer layer and an outer layer, and the coating liquid is a mixture of the following raw materials in parts by weight: 25-35 parts of aluminum sol, 5-8 parts of modified hyperbranched polymer, 2-4 parts of polyvinyl pyrrolidone, 1-3 parts of sodium lauryl sulfate, 5-7 parts of polyacrylate resin, 4-6 parts of modified chitosan, and 45-55 parts of deionized water; after the base membrane is coated with the coating liquid, a composite membrane is obtained, which has excellent adhesion, hydrophilicity and drip anti-fogging performance.

The utility model relates to a protective device for unmanned plane, the protective device for unmanned plane through being provided with the protection spare, can realize the good protection effect to the camera in the process of using, thereby avoided the damage under the action of external force, through transmission member and camera transmission connection, can drive transmission member to produce the rotation, thereby avoided transmission member in the process of protecting the camera and the outer surface attached with the rain and snow or other impurities, thereby influence the definition in the camera shooting process, through the protection cover is hemispherical, its material is transparent acryl material, can further reduce the attachment of rain and snow in the process of using, when the rain and snow fall on the arc surface can flow away quickly. Through setting up acryl material, on one hand can guarantee its transparency, on the other hand can guarantee that it can have good mechanical properties.

The utility model provides a derusting device in a gas bottle can, which comprises a support, the support comprises a vertical part and a transverse part connected with the vertical part, the inner side of the support is movably connected with a frame through a rotating shaft, the end part of the frame is fixedly connected with an end plate, the inner side surface of the end plate is fixedly connected with a rubber pad, and the rubber pad is fixedly connected with the rotating shaft. A plurality of guide rollers are movably connected to the inner side of the frame, and a plurality of fixing frames are fixedly connected to the top of the frame. Compared with the prior art, the derusting device has the advantages that the support, the frame, the fixing frame, the first air cylinder, the first connector and the second air cylinder are arranged in a matched mode, the rotatable frame structure is designed, after the derusting device conducts derusting on the inner wall of the gas cylinder, the output end of the second air cylinder is ejected out, the second air cylinder rotates, and the whole frame drives the positioned gas cylinder to rotate; and the tail end of the frame rotates upwards, the gas cylinder inclines, and the end opening of the gas cylinder faces downwards, so that residual rust water in the gas cylinder can be quickly drained and completely discharged, and the rust removal treatment efficiency of the gas cylinder is improved.

The utility model relates to the technical field of water and soil loss prevention, in particular to a water and soil loss prevention device for land protection, an adjusting device comprises long grooves, the long grooves are formed in the surfaces of the two sides of a protection frame, two mounting plates are slidably connected to the interiors of the long grooves, two fixing plates are fixedly mounted on the surfaces of the two sides of the protection frame, and the fixing plates are fixedly connected with the long grooves. A threaded rod is rotatably connected between the two fixed plates, a rotating wheel is fixedly mounted on the surface of the threaded rod, sliding grooves are formed in the surfaces of the two sides of the protection frame, two movable plates are in threaded connection with the surface of the threaded rod, and connecting rods are fixedly mounted between the movable plates and the mounting plates. According to the water and soil loss prevention device, the problems that an existing water and soil loss prevention device can only be forcibly fixed to the ground through expansion bolts, fixing is not firm, and a slope protection net shakes and even falls off are further solved.
