The utility model discloses a kind of starry sky roller blind mechanism for car, comprising: main frame, fixed in sunroof roof interior, the main frame includes shell, slide rail and limit board;Roller blind cloth, roller blind cloth adopts three-layer composite structure, from inside to outside in turn is light-blocking base layer, buffer middle layer and light-transmitting surface layer;Optical fiber bundle, optical fiber bundle is in buffer middle layer in "S" shape path extension to avoid excessive stretch when winding up.Optical fiber bundle penetrates the three-layer structure of roller blind cloth, output end is flush with light-transmitting surface layer and is not outstanding, and the friction scratch when winding up is completely eliminated;Buffer middle layer in "S" shape path design, so that optical fiber can be along path slightly deformed when winding up stretch, avoid direct stress fracture, ensure that there is no extrusion when optical fiber winding, and optical fiber fracture rate is greatly reduced.

The application discloses a kind of detection devices for roadbed soil moisture content, it is related to roadbed soil moisture content detection technical field, including detection equipment and detection mechanism, the detection mechanism includes probe rod, driving structure, small lead screw head, connecting piece, anti-disturbance isolation sheath, axial convex strip and axial sewage tank;The application is used by probe rod, small lead screw head, connecting piece and driving structure cooperation, probe rod is rotated into the position to be detected, anti-disturbance isolation sheath and axial convex strip make probe rod be completely isolated with the hole wall soil in the process of rotation, avoid soil body to be driven, disturbed or compacted, cooperate with the sewage of axial sewage tank and the low-speed drive of worm and worm structure, will not destroy soil body original structure, realize undisturbed high-precision moisture content detection, improve the sewage effect of axial sewage tank by cooperation of inclined cutting block, spiral conveying rod, synchronous belt structure and first transmission structure, reduce the frequency of axial sewage tank blockage.
