The invention relates to a pipeline maintenance device, in particular to a pipeline robot, and aims to provide an upstream-advancing type fluid driving pipeline robot. The robot can travel for a long distance in a pipeline and maintain long working time, and has the advantages of simple structure and low cost. The upstream-advancing type fluid driving pipeline robot is characterized by comprising a pair of front shell and rear shell positioned inside the pipeline, a rotating shaft and a wind wheel, the rotating shaft is arranged on the axis of the pipeline, the front end and the rear end of the rotating shaft can be positioned in the front shell and the rear shell respectively, and the wind wheel is fixed on the rotating shaft and is used for driving the rotating shaft to rotate. The rotating shaft is connected with the rear shell through a bi-directional screw mechanism fixed at the rear end of the rotating shaft. Besides, a plurality to locking mechanisms used for preventing the front shell and the rear shell from retreating are arranged on the outer circumferential surfaces of the front shell and the rear shell respectively.
Description
technical field [0001] The invention relates to a pipeline maintenance device, in particular to a pipeline robot. Background technique [0002] In the 21st century, there is a serious contradiction between my country's environmental pollution and rapid economic development, and natural gas, as a clean and environmentally friendly new energy, can just alleviate this contradiction. Now my country has built nearly 100,000 kilometers of natural gas transmission pipelines, which are responsible for relatively important energy transmission tasks. In order to keep the natural gas pipeline in good running condition for a long time, the maintenance of the pipeline is more critical. [0003] At present, pipeline robots are mainly used to maintain pipelines, but the existing pipeline robots generally need to be driven by external energy supply, the working time and travel distance inside the pipeline are relatively limited, and the reverse air flow is even more insufficient, which nee...
