Description

Technical Field

[0001] This utility model relates to the field of coal mine transportation technology, specifically to a device for preventing the failure of an automatic coal flow sensing probe. Background Technology

[0002] In coal mine production, belt conveyors are one of the main pieces of equipment for coal transportation. For a single conveyor belt in the main coal transportation system, the presence of coal flow above the belt is crucial information for belt speed regulation, dust suppression device activation, and coal bunker carbon release. Accurately determining the presence of coal flow above the belt is a fundamental prerequisite for saving operating costs and achieving energy conservation and emission reduction goals. Therefore, coal flow systems often install sensors at the coal bunker discharge ports underground. When one coal bunker is undergoing carbon release operations, the main coal flow transportation control system receives the information, automatically activating the spray system at that bunker's discharge port, while preventing other bunker feeders from starting carbon release operations. However, older coal flow sensors often use flexible materials like iron chains as sensing probes. While these chains buffer and release the impact of the coal flow, they can also swing excessively under the impact of the coal flow system, getting caught in other positions and causing the sensors to malfunction.

[0003] Therefore, existing technologies need further development. Utility Model Content
