[0028] In recent years, significant progress has been made in in-boiler drone inspection technology, which has gradually become a standardized operating method for power plant equipment inspection. This technology mainly uses visual inspection methods to conduct a comprehensive inspection of the boiler interior, greatly improving inspection efficiency and safety. However, in practical applications, existing drone systems still have obvious technical limitations. Due to equipment configuration constraints, the cameras carried by current mainstream inspection drones inevitably have blind spots, especially in image acquisition of critical areas such as the boiler roof. This technical deficiency results in the inability to obtain effective inspection data in some areas, posing a potential risk to the long-term safe operation of boiler equipment. As the power industry's requirements for equipment reliability continue to increase, how to overcome existing technical bottlenecks and achieve blind-spot-free inspection of the boiler interior has become an important issue that urgently needs to be addressed in this field.

[0029] This application proposes an image acquisition device and a drone, which aims to achieve controllable pitch angle rotation of the top area within a closed boiler space, solving the problem of blind spots in traditional fixed-view shooting.
