Abstract

The invention relates to an asymmetric variable-diameter wheeled waterproof pipeline robot, which includes a waterproof walking mechanism, a variable-diameter mechanism, a camera detection device and an anti-jamming device. Around the circumference, the camera detection device is fixed at one end of the variable diameter mechanism, and the variable diameter mechanism is connected with an anti-seize device, and the single waterproof running mechanism is a four-wheel running mechanism. The invention solves the problem that the existing pipeline robot needs to adapt to the change of pipe diameter and the rigid and inflexible symmetrical diameter reduction mode of the existing variable diameter structure, and simultaneously solves the problem of sealing and waterproofing of the pipeline robot and avoids the problem of jamming during detection in the pipeline.

Description

technical field [0001] The invention relates to the field of robots, and relates to an asymmetric variable-diameter wheeled waterproof pipeline robot used when it is impossible to manually detect pipelines with accumulated water. Background technique [0002] Existing pipeline robot diameter-changing structures all adopt parallelogram structure, the diameter-changing range is small and the diameter-changing method is relatively rigid and inflexible, and the driving force requirements for the robot are very large when the robot is moving forward and adapting to the change of the pipe diameter. [0003] In the case of water accumulation in the pipeline, the key issue in the development of the pipeline robot is the waterproof sealing of the pipeline robot. Studies have shown that when testing in pipelines with accumulated water, the failure of the robot due to sealing problems is higher than that due to problems such as electronic devices. The sealing of the pipeline robot is ...
