Description

Technical Field

[0001] The utility model relates to the technical field of inspection robots, in particular to an intelligent inspection device for a coal conveying system of a thermal power plant. Background Art

[0002] The coal transportation system is the lifeline of thermal power plants, which includes complex links such as coal loading and unloading, transfer, screening, crushing, and transportation. Each factory building contains a large number of mechanical equipment and special operating environments. Timely detection and timely maintenance of equipment failures are necessary responsibilities of inspection work. Manual inspection methods have many disadvantages, which pose many safety hazards to the safe operation of equipment and normal production safety. The use of factory inspection robots instead of manual inspection methods can effectively solve the many disadvantages of manual inspections.

[0003] However, in the coal transportation system of thermal power plants, coal unloading facilities, transfer stations, coal crusher rooms, and coal bunker rooms are prone to generating a large amount of dust. Currently, the most effective dust removal method for thermal power plants is spray dust suppression combined with other methods. Coal dust contains moisture, and after falling into the inspection track, it is adsorbed on the track surface, causing a large amount of coal dust to remain in the mobile mechanism, making the walking mechanism of the inspection robot very prone to failure.

[0004] To this end, we propose an intelligent inspection device for the coal transportation system of a thermal power plant. Utility Model Content
