Pull-type effective load laying device based on underwater robot

The invention relates to the technical field of underwater robots, and in particular relates to a pull-type effective load laying device based on an underwater robot. Compared with the prior art, the pull-type effective load laying device and method based on the underwater robot are provided according to the underwater fixed-point laying requirement under the severe environment such as the flowing water area, the underwater robot can be in the shape similar to a torpedo or a frame type, high power and maneuverability are achieved, and thus the drag and gravity generated by a pull-type effective load can be resisted; meanwhile, the underwater robot carries a detection instrument, the thickness of an ice layer can be detected, the fixed-point laying position can be judged according to the thickness of the ice layer, and the laying device body is provided with a cylindrical launching channel, a pull ring mounting hole and a traction rope storage chamber; a communicating pipeline is machined between the cylindric
