Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment technology, specifically a material silo monitoring device based on lidar. Background Technology

[0002] LiDAR (Light Detection and Ranging) is a remote sensing technology that measures distance and acquires three-dimensional information of target objects by emitting laser beams. It calculates distance by utilizing the time it takes for a laser pulse to return after interacting with a target object, and constructs a three-dimensional model of the target object's surface through scanning with multiple laser beams. A LiDAR-based material silo monitoring device is an intelligent system used for real-time monitoring and management of stored materials. It uses LiDAR technology to acquire information such as the location, shape, and quantity of materials, helping warehouse managers optimize warehousing processes, improve work efficiency, and ensure the safety and accuracy of materials.

[0003] Most existing lidar-based material silo monitoring devices do not have a lens cleaning structure. Material silos generally contain a lot of dust, which easily adheres to the lidar monitor lens, significantly affecting the scanning clarity during monitoring and impacting the safety and accuracy of material monitoring. Utility Model Content

[0004] The purpose of this invention is to address the problem that most existing lidar-based material silo monitoring devices do not have a lens cleaning structure, resulting in significant dust accumulation in the material silo.

Therefore, this invention provides a lidar-based material silo monitoring device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a material silo monitoring device based on lidar, comprising: a connecting base plate, a central column fixedly connected to one end of the bottom surface of the connecting base plate, a limiting ring fixedly sleeved on the outer side of the bottom end of the central column, a connecting rod fixedly connected to the bottom end of the central column, a wide-angle lidar installed at the bottom end of the connecting rod, a driven gear disk sleeved on the outer side of the central column, a movable slot frame fixedly connected to the bottom surface of the driven gear disk, a servo motor fixedly connected to one end of the movable slot frame, a rotating screw provided at the output end of the servo motor, a movable slider screwed to the outer side of the rotating screw, a cleaning rod fixedly connected to one side of the movable slider, a cleaning brush provided on one side of the bottom of the cleaning rod, a rotating motor fixedly connected to one end of the top surface of the connecting base plate, and a drive gear disk fixedly sleeved on the output shaft of the rotating motor.

[0006] As a further embodiment of this utility model: the movable slot frame is configured to have a sliding groove inside, and it is radially fixed on the bottom surface of the driven gear plate. The rotating screw and the movable slider are both located inside the sliding groove of the movable slot frame, and the movable slider is sleeved on the rotating screw and connected by a screw.

[0007] As a further embodiment of this utility model: the sweeping rod and its connecting structure are both fixed to the bottom end of the movable slider, and the sweeping rod and the sweeping brush move parallel to the connecting rod and move with the movable slider.

[0008] As a further embodiment of this utility model: the drive gear disk and the driven gear disk are meshed together, and the rotating motor drives the drive gear disk to rotate, thereby driving the driven gear disk to drive the sweeping rod and its connecting structure to rotate around the wide-angle laser radar.

[0009] As a further embodiment of this utility model: an installation chamber is fixedly connected to the top surface of the connecting base plate, an installation ear plate is fixedly connected to the edge of the top surface of the installation chamber, an installation bolt is passed through one end of the installation ear plate, and the rotating motor is located between the installation chamber and the connecting base plate.
