Abstract
This utility model discloses a cylindrical light source device for detecting internal defects in oil drums, comprising a coaxially connected hollow tube I and a hollow tube II. Hollow tube II is surrounded by an LED light panel and fitted with an optical diffuser tube. Industrial cameras with protective covers are symmetrically mounted at both ends. Modular assembly is achieved through hollow tube fixing components and diffuser tube fixing plates. The detection head fixing component is connected to an external lifting mechanism. This device can penetrate deep into the inspection port of the oil drum, achieving shadowless illumination using the diffuser tube. The dual cameras work together to complete 360° panoramic imaging, significantly improving the defect detection rate in confined spaces.
