An irrigation device for seedling planting
ActiveCN224368618UFlexible control of swing ratemeet irrigation needsMovable spraying apparatusWatering devices
This utility model relates to the field of irrigation equipment and discloses an irrigation device for seedling planting, including a base. A swing rod is hinged to the top of the outer surface of the base. A sliding block is slidably connected to the inner surface of the swing rod. A column is fixedly connected to the rear part of the outer surface of the sliding block. A rod body is hinged to the top of the outer surface of the base. A groove is formed on the front of the outer surface of the rod body, and the rear part of the outer surface of the rod body is slidably connected to the inner surface of the groove. A threaded rod is rotatably connected to the inner surface of the swing rod. In this utility model, through the cooperation of components such as the knob, threaded rod, threaded sleeve, sliding block, and column, the operator can adjust the position of the sliding block by rotating the knob, thereby adjusting the traction point of the rod body, to flexibly control the swing rate of the nozzle, based on the size of the seedling planting area and the water requirements of the seedlings at different growth stages. This meets the irrigation needs of different planting scenarios.

An eccentric adjustment structure
PendingCN122077411Aeasy to completeaccurate captureLarge fixed membersPositioning apparatusNumerical controlClassical mechanics
This invention relates to the field of eccentricity adjustment, specifically to an eccentricity adjustment structure comprising a mounting frame, an adjusting seat, and an eccentricity adjustment device. The eccentricity adjustment device includes a positioning center wheel, an eccentricity adjustment bracket, an adjusting member, and an eccentricity adjustment assembly that drives the adjusting member. The positioning center wheel is fixedly disposed in the middle of the mounting frame. The adjusting member includes a first adjusting member and a second adjusting member. One end of the first adjusting member is connected to a first adjusting seat, and the other end of the first adjusting member is connected to the eccentricity adjustment bracket via the positioning center wheel. One end of the second adjusting member is connected to a second adjusting seat, and the other end of the second adjusting member is connected to the eccentricity adjustment bracket via the positioning center wheel. This eccentricity adjustment structure can be used for machining eccentric or coaxial workpieces, accurately determining the eccentricity and thus establishing the initial machining positioning datum. Even during subsequent machining processes, the machining positioning datum remains accurate, facilitating the completion of eccentric or coaxial workpieces using CNC machine tools.

A deep learning-based method for multi-target pedestrian tracking
ActiveCN117237411BAccurate detectionAccurate estimateImage analysisInternal combustion piston enginesVisual technologyComputer graphics (images)
This invention provides a deep learning-based method for multi-target pedestrian tracking, relating to the field of computer vision technology. The method includes: S1 acquiring video data, extracting frames from the video data to convert them into image frames, and preprocessing the image frames; S2 using an improved YOLOv5-s model to detect pedestrian targets in the image frames, obtaining the pedestrian targets; S3 using an improved Strong SORT model to track the pedestrian targets in each frame, assigning an ID to each tracked pedestrian, and generating pedestrian tracking results. This invention can accurately locate each pedestrian in a video and track their trajectory.

A robot arm positioning method based on a language model and a 3D point cloud
This invention discloses a robotic arm localization method based on language models and 3D point clouds, comprising the following steps: acquiring images of human-object interaction; expanding the object's 3D point cloud dataset based on Gaussian splash and diffusion models, and adding question-and-answer text information; encoding the object's 3D point cloud to obtain 3D point cloud feature vectors; acquiring text feature vectors; aligning the dimensions of the 3D point cloud feature vectors and text feature vectors; combining them to obtain feature vectors; obtaining the hidden layer of the current feature vector; extracting the hidden layer of the last layer of a set term; mapping the dimensions of the hidden layer back to the dimensions of the 3D point cloud feature vectors to obtain feature vectors used to constrain point cloud decoding; inputting the 3D point cloud feature vectors into a multi-layer point cloud decoder for decoding; converting the feature vectors output by the point cloud decoder into a heatmap of the point cloud to obtain the corresponding action region. This invention can solve the problem of insufficient generalization ability of existing models and improve the adaptability to dynamic environments and tasks.

A deformable leg exoskeleton
ActiveCN117301023Beasy to completeeasy to operateProgramme-controlled manipulatorBone structurePhysical therapy
This invention discloses a deformable leg exoskeleton, comprising: two sets of first and second legs, and a first and second strap assembly respectively disposed on the first and second legs; a lumbar support structure is provided at the end of the second leg away from the first leg; it also includes a meshing transmission assembly disposed at the opposite ends of each set of first and second legs, and a wheel assembly disposed at their opposite ends, with each wheel assembly, the first leg, and the second leg together forming a rectangular bone frame. Through structural design, this invention allows the exoskeleton to adjust its posture in real time according to the movement of the hip and knee joints, thereby providing auxiliary support after changes in standing and sitting postures, helping the wearer to better complete the corresponding movements, and simultaneously realizing an auxiliary bone structure integrating walking, exercise, and rest.
