A biomimetic mother-of-pearl interlocking structure hydrophobic hemp fiber-based radiation cooling membrane and its preparation method are disclosed, belonging to the field of radiation cooling technology. To address the problems of environmentally unfriendly raw materials, high cost, complex preparation processes, and low cooling efficiency in existing radiation cooling materials, this invention provides a preparation technology for a hemp fiber-based biomimetic radiation cooling membrane and a flexible fabric coating. Using industrial hemp recycled fibers as the core green matrix, through synergistic design of material innovation, structural innovation, and process innovation, it comprehensively solves the technical defects of existing radiation cooling materials, providing a new green solution for the large-scale application of radiation cooling technology in multiple scenarios. This radiation cooling membrane, using recycled industrial hemp fibers as the matrix, combines the characteristics of being environmentally friendly, having a biomimetic interlocking structure, and providing high-efficiency radiation cooling. The preparation process is simple and can be mass-produced, meeting the application needs of multiple fields such as building energy conservation, outdoor equipment manufacturing, electronic equipment thermal management, and agricultural greenhouse film control.

The present application relates to the technical field of obstacle removing equipment, and discloses an intelligent laser breaking and removing device with inclination angle protection, which comprises a laser breaking main body shell, a plurality of small lenses and large lenses, and a heat prevention and control assembly is arranged in the laser breaking main body shell and used for autonomously protecting the zoom lens; the heat prevention and control assembly comprises an outer pipe which is arranged in the laser breaking main body shell, and the plurality of large lenses are coaxially arranged on the inner wall of the outer pipe through first fixing rings. The device is matched with the outer pipe, the inner rotating sleeve pipe, the T pipe, the one-way valve, the first fin, the second fin and low-temperature nitrogen, the inner rotating sleeve pipe rotates to drive the T pipe to reciprocatingly move along the inner cylinder axis, negative pressure and positive pressure are generated by the volume change of the first cavity and the second cavity, the waste gas carrying heat after absorbing the heat of the lenses can be discharged in time during the reciprocating transverse movement of the T pipe, and the low-temperature nitrogen is sucked to carry out a new round of cooling, so that the small lenses and the large lenses are comprehensively cooled and protected.
