Description

Technical Field

[0001] The utility model relates to the technical field of drainage robots, and particularly relates to a crawler-type double self-priming pump drainage robot. Background Technique

[0002] During periods with more rain, many low-lying areas will be flooded by rainwater, which will bring inconvenience to the passage of roads, underground garages, and tunnels. People usually adopt manual cleaning for the sewage in low-lying areas, and this manual drainage method is very inefficient. Therefore, we can use drainage robots to replace humans to undertake this work. The drainage robot uses a crawler drive form to move forward and backward, and completes the extraction and discharge of sewage through the internal water pump.

[0003] When the drainage robot cleans sewage, it generally pumps water through the drainage pipe on the drainage robot. Based on safety considerations, the length of the drainage pipe is fixed and cannot be adjusted, resulting in that the drainage robot can only extract water at a certain water surface height and cannot extract water from some low-lying positions, which is rather inconvenient.
