Problems solved by technology

[0004] The anti-winding device uses the movement of the propeller to cooperate with the moving knife and the fixed knife mechanism to realize the anti-winding of the propeller. It has a simple structure and can prevent debris from being entangled to a certain extent. Covered by sundries, it loses its cutting effect, and it is necessary to manually remove the sundries on the fixed knife mechanism;
[0005] Therefore, how to solve the problem in the prior art that the fixed knife mechanism is entangled by debris and covered inside has become an important problem that those skilled in the art need to solve urgently.

Abstract

The invention discloses an anti-winding device for a ship propeller, and belongs to the technical field of ship equipment. The anti-winding device comprises a stern shaft bracket arranged outside a stern shaft in a sleeving mode, a propeller arranged at one end of the stern shaft bracket and fixedly connected with the stern shaft, and a cutting mechanism; the cutting mechanism comprises a shell fixedly connected with the stern shaft bracket; a cavity for accommodating a cutter is formed in the shell, and a through groove communicated with the cavity is formed in the side wall of the shell; and a driving mechanism is arranged on the shell and used for driving the cutter to stretch out and draw back in the through groove of the shell. The anti-winding device has the beneficial effects that entanglement can be actively cut, self-rescue is achieved, and the cutting efficiency is high.

Description

technical field [0001] The invention relates to the technical field of ship equipment, in particular to a ship propeller anti-winding device. Background technique [0002] When the ship moves forward in the water, it will be entangled by floating objects, fishing nets, cables and other sundries in the water, which will affect the speed of the ship in the slightest, and increase the resistance of the propeller or even block the rotation, causing ship accidents; [0003] In the prior art, a Chinese utility model patent, the application number is 201520077526.X, the application date is February 04, 2015, and the announcement number is CN204433006U "An Anti-winding Device for Ship Propellers" includes propellers, stern shafts, Stern shaft frame and cutting device, one end of the stern shaft is set in the stern shaft frame and connected to the output shaft of the main engine, the other end is connected to the propeller, the cutting device includes a moving knife and a fixed knife...
