The invention relates to the technical field of hygroscopic materials, and particularly discloses an atmospheric hygroscopic material for ecological restoration of arid-semi-arid regions and a preparation method of the atmospheric hygroscopic material. The method comprises the following steps: firstly preparing gel containing a heat-conducting material, acrylamide and isopropyl acrylamide, freeze-drying the swelled gel, soaking the gel in a moisture-absorbing salt water solution to load moisture-absorbing salt, taking out and drying. The temperature sensitivity of isopropylacrylamide is retained through copolymerization of acrylamide and isopropylacrylamide monomers, meanwhile, higher hydrophilic performance is given to isopropylacrylamide, a high-molecular polymer can absorb liquid drops formed by deliquescence of moisture absorption salt, continuous adsorption of the moisture absorption salt is kept, and the polymerized gel has higher moisture absorption capacity and water yield. The prepared atmospheric hygroscopic material provides a new way for supplying water required by ecological restoration plants in arid-semi-arid regions, water vapor is collected without depending on an external device in use, and the water production process is free of energy consumption and emission and environmentally friendly.

This utility model discloses a lithium-ion battery-powered multifunctional rail grinding machine, including a frame, and grinding components, a feed adjustment component, a contour wheel component, a handrail component, and a power battery pack component mounted on the frame. A pressure sensor monitors the grinding pressure in real time, and the feed adjustment component automatically adjusts the pressure between the grinding wheel and the rail to ensure the grinding pressure is always maintained at the optimal level. The feed method uses a motor-driven threaded transmission, which is simple, reliable, and offers high adjustment precision. The handrail component is reasonably designed, allowing for flexible adjustment of the grinding angle via an angle adjustment plate. Combined with the auxiliary wheel design, it can stably complete the grinding of the top, side, and curved surfaces of the rail. Powered by a lithium battery, it is convenient for field operations. This utility model has a reasonable structure, is easy to operate, and can improve the quality and efficiency of rail grinding.

This invention discloses a point cloud nesting cutting device and method for a dead-end pipe, comprising two cutting robots and two tracks for each of the cutting robots to traverse; the two ends of the tracks are connected by a snap-fit ​​device to form a ring structure surrounding the material pipe; it also includes a handheld 3D scanning device for scanning the dead-end pipe, the cutting torch, and the tracks to generate point cloud data with spatial position information; and a first calculation module for calculating the cutting parameters of the two pipes based on the point cloud data obtained by the handheld 3D scanning device. The advantages of this invention are: highly automated calculation process; low operational difficulty; and the addition of 3D scanning of the material pipe and tracks, enabling automatic deviation correction of the cutting robots.
