The application discloses a height-adjustable obstacle-avoiding structure of a patrol robot, which is used for avoiding flexible linear obstacles and comprises upper and lower rotating discs, a plurality of telescopic supporting rods, guide members and a poking member. The upper and lower rotating discs are synchronously rotated and are respectively in rotating cooperation with upper and lower shells of the robot, the plurality of telescopic supporting rods are arranged in a circumference between the two rotating discs and can swing towards a rotating disc axis, the guide members are sleeved on the telescopic supporting rods and axially float, and a limiting member is arranged between adjacent guide members. The poking member is of a telescopic structure, is provided with a poking rod, is universally connected with the robot shell, an elastic reset member is arranged at a connecting position, the poking member is located at a rear side of a robot advancing direction and is in an extended posture in a natural state. The height-adjustable obstacle-avoiding structure of the patrol robot has the beneficial effects of self-adapting robot height adjustment and active off-line anti-winding.

The utility model relates to the technical field of fixing supports, in particular to a drainage pipeline adjustable fixing support which comprises an adjusting support and an adjusting hoop, and the adjusting hoop comprises a connecting block, an adjusting bolt, a rotating arc piece, a connecting bolt and a top hoop. When the adjusting shroud ring is used, the top ring is rotated, the top ring is moved downwards to be away from the rotating arc pieces, the distance between the two rotating arc pieces is observed, the adjusting bolt is rotated, the included angle between the two rotating arc pieces and the connecting block is adjusted, and the distance between the two rotating arc pieces is enlarged or reduced till the distance is adjusted to be slightly larger than the diameter of the drainage pipeline. The drainage pipeline is arranged between the two rotating arc pieces, the adjusting bolt is rotated again to enable the two rotating arc pieces to clamp the drainage pipeline, finally, the top hoop is rotated reversely, the top hoop is moved upwards and abuts against the drainage pipeline, and then the drainage pipeline is fixed, and the adjusting shroud ring can be directly adjusted according to the size of the drainage pipeline needing to be fixed. And the laying of drainage pipelines with different pipe diameters can be compatible.
