Description

TECHNICAL FIELD

[0001] The utility model relates to the field of inspection device, especially a coal conveying inspection device for thermal power plant. BACKGROUND

[0002] The inspection device is used for the regular inspection of a specific area, equipment or system, and is composed of sensors, data collectors, transmission modules, control centers and the like, and can monitor various information in real time and transmit the information to the control center for processing. In the coal conveying process of the thermal power plant, the application of the inspection device is extremely crucial. The coal conveying system is complex and prone to faults during long-term operation. The inspection device can monitor the temperature, vibration, speed and other parameters of the equipment in real time, detect abnormalities in a timely manner, avoid the expansion of faults, ensure the safe operation of the equipment, and thus improve the production efficiency. The data collected by the inspection device can also help to develop a scientific maintenance plan, realize preventive maintenance, optimize maintenance management, reduce costs and prolong the service life of the equipment. In addition, due to the complex environment of the coal conveying system and the presence of many dangerous factors, the inspection device can replace manual work in dangerous areas, reduce personnel safety risks and ensure personnel safety.

[0003] The existing coal conveying inspection device for thermal power plants converts the physical quantities of equipment operation into electrical signals or digital signals by means of various sensors such as temperature, vibration, displacement and coal flow deployed at key positions of the coal conveying system. The data collector collects and pre-processes these signals at a specific frequency and accuracy, and then transmits them to the control center through wired or wireless means. The computer system of the control center analyzes the data using algorithm models, judges the equipment state by means of trend analysis and threshold comparison, and summarizes the operation rules by mining historical data. Finally, the processed data is presented to the operator in a visual interface, and the device alarms in various ways when it is abnormal to ensure the safe and stable operation of the coal conveying system.
