Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Examples

As shown in fig. 1 and 2, a manipulator for cleaning a well chamber comprises a framework 1 and a grabbing assembly, wherein the grabbing assembly comprises at least one group of grabbing petals 2, the number of the grabbing petals 2 in each group is two, and the grabbing petals 2 in the same group are arranged oppositely. As shown in fig. 3, as a preferred embodiment, the number of the grapple flaps 2 is two, and four grapple flaps 2 are annularly distributed.

As shown in fig. 1 and 2, the grasping tab 2 includes an operating portion 21 and a grasping portion 23, and the center of gravity of the grasping tab 2 is located at the grasping portion 23. A transition part 22 is arranged between the operation part 21 and the grabbing part 23, and the transition part 22 is rotatably and movably connected with the framework 1.
