Abstract
Description
Technical Field
[0001] This utility model relates to the field of cement pole detection technology, specifically a cement pole surface defect detection device. Background Technology
[0002] In the field of cement pole surface defect detection, traditional detection devices generally face the dual challenges of interference from surface contaminants and the risk of missed detection. In existing technologies, optical detection equipment (such as laser displacement sensors and visual imaging systems) is easily interfered with by dust, mud, and other adhering substances, resulting in distortion of the sensor's received signal. Especially on rough surfaces, contaminants are easily misjudged as cracks or used to mask real defects. On the other hand, manual inspection or mechanical contact detection methods are limited by the conical pole structure or complex surface morphology, making it difficult to achieve seamless coverage around the entire circumference and prone to detection blind spots. To address these issues, we propose a cement pole surface defect detection device. Utility Model Content

[0023] The working principle of the cement pole surface defect detection device provided by this utility model is as follows: The cement pole is axially conveyed by the conveying roller 31 of the conveying component 3. The first motor 32 drives multiple sets of conveying rollers 31 to rotate synchronously through the linkage of the sprocket ring 34 and the chain 35, ensuring the smooth movement of the cement pole. When the cement pole enters the installation frame 1, the second motor 42 of the cleaning component 4 drives the first gear 43 to mesh with the first gear ring 47, driving the rotating ring 44 to rotate. The cleaning wire 46 inside dynamically cleans the surface of the cement pole through the strip-shaped opening 45. The dust generated by the cleaning is sucked into the dust collection box 61 through the air inlet 62 by the exhaust fan 63 of the dust collection component 6. The blocking net 64 intercepts large particles of impurities, and the baffle 65 facilitates the later cleaning of accumulated dust. Subsequently, the cement pole enters the area of the detection component 5. The third motor 57 drives the second gear 58 to mesh with the second gear ring 55, driving the connecting ring 52 to rotate at a constant speed around the fixed ring 51. The four cameras 53 rotate synchronously with the connecting ring 52 to achieve 360° no-dead-angle shooting. The camera 53 transmits image data to the external PLC controller in real time through the brush slip ring 54. The surface defects are identified through the image comparison algorithm. Throughout the process, the PLC controller coordinates the start, stop and speed of the first motor 32, the second motor 42, the third motor 57 and the exhaust fan 63 to ensure the timing of the cleaning, dust extraction and detection actions are synchronized. Finally, the device is kept running stably by the base plate 8 and the support legs 7.
[0024] It is worth noting that the external PLC controller disclosed in the above embodiments is specifically a Siemens S7-200. The first motor 32, the second motor 42, the exhaust fan 63, the camera 53, and the brush slip ring 54 can be freely configured according to the actual application scenario. The external PLC controller controls the operation of the first motor 32, the second motor 42, and the exhaust fan 63 using methods commonly used in the prior art.
