The counterweight arm structure is installed on a propeller root outer sleeve and comprises a first joint sleeve plate, a second joint sleeve plate, a supporting arm and a balancing weight, joint grooves are formed in the inner side wall of the first joint sleeve plate and the inner side wall of the second joint sleeve plate, a joint flange is annularly arranged on the propeller root outer sleeve, and the supporting arm is arranged on the joint flange. The first joint sleeve plate and the second joint sleeve plate are both of a semicircular structure and are fixedly connected to the paddle root outer sleeve in an embracing mode, the joint flange is connected with the joint groove in a matched and clamped mode, and the supporting arm is integrally and fixedly connected to the convex side of the second joint sleeve plate. The end, away from the second joint sleeve plate, of the supporting arm is provided with a balancing weight connecting part, and the balancing weight is detachably connected to the balancing weight connecting part. The device is easy to install, and the blades can be rapidly repaired by replacing the balancing weights. The positioning precision is high, mounting and dismounting are convenient, the structural reliability is high, and the mounting and maintenance cost is effectively reduced.
