Title: Innovations of Lei Si in Environmental Monitoring and Hydraulic Support Systems
Introduction
Lei Si is an accomplished inventor based in Xuzhou, China. He has made significant contributions to the fields of environmental monitoring and hydraulic support systems, holding a total of 4 patents. His work focuses on enhancing the efficiency and safety of mining operations through innovative technologies.
Latest Patents
One of Lei Si's latest patents is an "Environmental Monitoring Apparatus and Method for Mine Tunneling Robot." This apparatus includes a current excitation source, a roadheader telescopic protection cylinder, an electric rotating apparatus, auxiliary cutting teeth, a cutting head entity, a transmission shaft, an optical fiber ring protective housing, an optical fiber ring, an optical fiber current sensor control unit, and a recovery electrode. The apparatus transmits an auxiliary current and a monitoring current to a coal seam, allowing for effective environmental monitoring. The monitoring current flows to the coal seam, while a return current flows through the transmission shaft and a roadheader expansion part. The optical fiber ring measures the return current when the roadheader encounters abnormal geological bodies.
Another notable patent is for a "Hydraulic Support Monitoring Support Pose in Real Time Based on Inertia Measurement Unit and Detection Method Thereof." This invention utilizes IMU sensors mounted on various components of the hydraulic support to monitor its pose in real time. The system processes the movement states to determine whether the hydraulic support is adequately lowered, moved, or raised. This innovation effectively reduces the labor intensity of workers and improves the working efficiency of hydraulic supports.
