Description

Technical Field

[0001] The utility model relates to the technical field of power equipment detection, in particular to an intelligent detection device for a fan in a power plant. Background Art

[0002] With the continuous expansion of the capacity of power plants, the installed capacity across the country is also increasing. Regardless of the size of the power plant, the forced draft fan and the induced draft fan are important auxiliary machines of the power plant. In addition, the operating environment of the fan is generally characterized by high temperature, high pressure, and high impurities. It is easy to have some abnormal working conditions that threaten the safety of power plant production. Blade breakage is a problem caused by the operation of the induced draft fan of the power plant boiler. When the fault occurs, more cracks will be observed on the outside of the blade. These cracks mainly extend from the thicker area to the thinner area, or there is a break on one side of the blade. During the material inspection process, it was found that the cracks in the thicker areas of some blades were in the coating. Under the microscope, there are many holes around some cracks. In the process of crack failure development, the fracture is mainly caused by continuous extension and extension, with lateral extension and longitudinal extension. Most cracks extend from the surface of the blade to the outside, or from the body material to the inside. In the process of equipment management, if an effective response strategy is not proposed in a short time, the crack problem will be further aggravated. Under the action of stress, a part of the thinner area of ​​the blade has a more serious fracture, and the cracks extend in all directions. In addition, some blades were processed during the initial production and installation. However, during use, due to the temperature difference and expansion system differences between the materials, large stress remains inside. If the equipment is affected by the surrounding environment, the crack problem will become more and more serious. In addition, the unqualified coating process and spraying quality will also have a serious impact on the use of materials, forming a weak area of ​​performance on the surface. The material is highly sensitive and cracks are generated. The generation of cracks is closely related to the operation of the blades. During the operation of the blades, they will be subjected to greater wind pressure intake, and a certain tensile stress will appear on one side of the blade. At this time, they will be affected by smoke and dust, which will continuously wash the surface of the blades, causing more serious wear.

[0003] Currently, crack detection of wind turbine blades is done manually, which relies on the experience, skills and judgment of the inspectors. Different people may have different judgments, resulting in subjectivity and uncertainty in the inspection results. It takes a lot of time and manpower to achieve fast and efficient inspection. There may be safety hazards, especially for high-speed rotating wind blades, where the safety risk of personnel is relatively high. Utility Model Content
