[0052] In harsh environments such as direct sunlight or rain, when protection of the rail flaw detector's main unit is required, rotate the handle to fully extend the sunshade, forming a protective shield. Figure 1 As shown, the rail flaw detector main unit is fully protected by a light shield and a main unit protective cover. When it is necessary to operate the main unit screen of the rail flaw detector, the light shield is partially retracted by rotating the handle, for example, forming... Figure 4 As shown in the diagram, the sunshade prevents direct sunlight from hitting the main unit screen and reduces the amount of raindrops falling on it, allowing the inspection personnel to clearly observe the information displayed on the screen and perform relevant operations. In practical applications, the sunshade can be partially or fully retracted when the main unit screen needs to be operated, depending on the specific requirements. After the inspection personnel have finished operating the equipment, the sunshade can be fully extended to provide comprehensive protection for the rail flaw detector main unit.
