[0029] Working principle: When using this device, first add water to the water tank 1, hold the two push handles 3, and move the device to a suitable position with the help of the movable base 2; then, turn on the second motor 36, display screen 41 and camera 10 through the PLC controller. The second motor 36 drives the threaded rod 37 to rotate, and the lifting block 38, which is threaded with the threaded rod 37, moves upward along the outer shell 33, driving the connected lifting column 39 to rise. The lifting column 39 then drives the mounting plate 12 to rise. At the same time, the sliders 40 on both sides of the lifting block 38 slide in the slide groove 34 to ensure smooth lifting. Stable; if further height is needed, the PLC controller controls the second electric push rod 13 to start, driving the lifting platform 5, vertical plate 6, and mounting box 9 to continue rising until the camera 10 connected to the mounting box 9 reaches one side of the bridge support, and then the second electric push rod 13 is turned off; during the shooting process, the device can be moved as needed. At the same time, the PLC controller commands the pressurization pump 29 and the first motor 23 to start. The pressurization pump 29 works, causing the water in the water tank 1 to enter the water spray pipe section 25 through the water inlet pipe 30, connecting hose 28, and connecting pipe 27 in sequence, and then by High-pressure nozzles 26 spray air onto the bridge bearings, washing away the attached dust. The first motor 23 drives the fan blades 24 to rotate, drawing outside air through the dust filter 15 into the mounting housing 9 via the air inlet 14. The air is then guided by the conical air guide 19, enters the blower 21 through the opening 20, and finally blown onto the bridge bearings by multiple blower pipes 22, drying the washed-off water. As the device moves, the camera 10 captures images of the cleaned bridge bearings, which are displayed in real-time on the display screen 41. During recording, the camera can be activated via the PLC controller as needed. The first electric push rod 7, in coordination with the two guide rods 8, drives the mounting box 9 to move horizontally, facilitating the camera 10 to capture images. If the light is dim, the supplementary light 11 can be turned on via the PLC controller to provide supplementary lighting for the bridge bearings being captured. During the visual inspection of bridge bearings, this device can wash away the attached dust and blow away the moisture, preventing dust from obscuring key defects such as cracks and corrosion on the bearing surface, thus improving the clarity of image acquisition and providing a more reliable basis for subsequent damage assessment based on image analysis.
