The application discloses a multifunctional anti-degeneration traditional Chinese medicine storage device, the fixed plate, the movable plate and the driving plate are movably connected with anti-degeneration placing assemblies for storing traditional Chinese medicinal materials, the anti-degeneration placing assemblies are provided with multiple groups, respectively, anti-degeneration placing assembly one, anti-degeneration placing assembly two, anti-degeneration placing assembly N, the anti-degeneration placing assembly one, the anti-degeneration placing assembly two, the anti-degeneration placing assembly N are movably connected on the fixed plate, the movable plate and the driving plate from bottom to top. The application belongs to the technical field of traditional Chinese medicine storage, and particularly relates to a multifunctional anti-degeneration traditional Chinese medicine storage device, which can batch store the same medicinal materials, simultaneously dry the same medicinal materials, and store two kinds of medicinal materials which can avoid mutual degeneration in the same place, so that the occurrence of mildew and degeneration of the two kinds of medicinal materials is reduced.

This invention provides a point cloud-based navigation method, system, device, and storage medium for quay crane areas. The method includes the following steps: navigating to the surrounding area of ​​the quay crane area using a first navigation path based on GPS positioning data; continuously scanning at least a portion of the quay crane area in the surrounding area to establish point cloud map data of cargo ships within the quay crane area; detecting GPS positioning signals in real time and matching point cloud objects in the point cloud map data with the GPS positioning data; generating a second navigation path based on the completed point cloud map data when the GPS positioning signal does not meet a preset signal strength threshold; and performing loading and unloading operations with the quay crane based at least on the second navigation path. This invention can fully utilize the edge information of cargo ships to achieve self-positioning of vehicles with six degrees of freedom, greatly improving the accuracy and safety of truck and quay crane alignment, even when cargo ships are docked at the quay and GPS positioning fails.

This utility model relates to the technical field of fuel-powered vehicles and new energy vehicles, and discloses a liquid-cooled plate riveting bracket anti-rotation positioning structure, including a bracket and a manifold. The bracket has a first rivet hole, and the manifold has a second rivet hole. The bracket is connected to the manifold by a rivet. The rivet passes through the first rivet hole and the second rivet hole to connect the bracket and the manifold. The end face of the manifold near the bracket has a circular hole structure, and the end face of the bracket has a square slot structure above the circular hole structure. A barb structure is integrally provided on the square slot structure. The barb structure passes through the circular hole structure. The barb structure of the bracket in this utility model can be inserted into the circular hole structure on the manifold. Finally, the rivet is installed. At this time, the relative position between the bracket and the manifold is unique, ultimately meeting the customer's requirements.
