The utility model relates to the technical field of solar lantern installation, and discloses a solar lantern support convenient to adjust, which comprises a supporting column, a reinforcing plate and a locking screw, an installation frame is arranged at the upper end of the supporting column, an adjusting assembly is arranged at the lower end of the installation frame, and the adjusting assembly comprises an adjusting block, an adjusting rod and an installation groove. According to the utility model, through the cooperative use of the contraction bin, the telescopic rod and the supporting rod, the fixing column moves along the sliding groove through the hand buckle, and at the moment, the supporting rod jacks up the mounting rack and rotates relative to the telescopic rod, so that the angle of the solar cell panel mounted on the mounting rack is adjusted; according to the solar lamp, the inclination angle of the solar cell panel can be conveniently adjusted, the solar energy conversion efficiency of the solar lamp is improved, an adjusting rod is arranged, and the adjusting rod and an adjusting block are installed through a rotating shaft, so that the illumination angle of the solar lamp can be adjusted up and down through the device, and the practicability of the device is improved.

The invention relates to the technical field of material preparation, and discloses a preparation method of a PC-SP-MCN double-layer Janus composite membrane for synergistically driving interface evaporation and photocatalysis by taking graft copolymerization and phase transformation as main synthesis methods. Secondly, the application of the composite membrane in seawater desalination and purification treatment of wastewater containing dye, heavy metal and biological pollution is introduced. In addition, the double-layer Janus composite membrane is prepared through phase transformation, and the introduced silicon dioxide grafted ionic liquid enables the material to have good salt tolerance. Through application research in the aspects of seawater desalination and purification treatment of wastewater containing dye, heavy metal and biological pollution, the PC-SP-MCN double-layer Janus composite membrane capable of coordinating solar-driven interface evaporation and photocatalysis prepared in the invention is preliminarily considered to have relatively high solar energy conversion efficiency; the photocatalyst has excellent salt resistance and pollution resistance and efficient photocatalytic degradation performance, and can be widely applied to the fields of seawater desalination, wastewater treatment and the like.
