Measuring vessel propelling device with anti-winding function

The invention relates to the technical field of ship propelling devices, in particular to a surveying ship propelling device with an anti-winding function, which is characterized in that a collecting groove is formed in the surface of a propeller shell, a rotating track is arranged in the propeller shell, and a plurality of groups of arc-shaped convex blocks are fixedly arranged on the surface of the rotating track; the collecting box is arranged below the propeller shell, and the collecting box corresponds to the collecting groove in position; the propeller is rotationally arranged in the thruster shell; in the process that the end, close to the driving mechanism, of the propeller shell enters the interior of the propeller shell, waterweeds and other sundries contained in water flow are blocked by the fixed cutter and hung on the surface of the fixed cutter, and when a propeller rotates to drive a rotating column to rotate to the position tangent to the fixed cutter, the waterweeds and other sundries are blo
