Abstract

The invention discloses an equipment testing method and device applied to a thermal power plant. The method comprises the steps of controlling an unmanned aerial vehicle to fly according to a preset testing route; collecting terahertz images or infrared images of inner and outer walls of thermal power plant equipment in the flight process of the unmanned aerial vehicle, wherein the thermal power plant equipment comprises a boiler, a chimney, a desulfurizing absorption tower and an air cooling island; and analyzing the terahertz images or the infrared images and determining the position of the defect of the equipment and the heat dissipation condition. The defects of the inner and outer walls of the thermal power plant equipment are detected by using the unmanned aerial vehicle instead of manpower, so that the human cost can be reduced, the time can be saved, and the testing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of equipment detection, in particular to an equipment detection method and device applied to thermal power plants. Background technique [0002] Thermal power units account for more than 60% of my country's power generation. Due to the low efficiency and environmental protection of small thermal power units, my country has shut down 90% of small thermal power units in recent years according to national conditions, and modern large-scale units also undertake 6%. Ten power generation. Boilers, chimneys, desulfurization absorption towers, air-cooling islands and other equipment in thermal power plants will produce plane defects such as cracks, metal delamination, scaling, and wear for a long time, which will affect the operation of the equipment, so the detection of equipment is particularly important. In the prior art, detection is usually done by manpower, which is time-consuming, laborious and inefficient. E...
