Abstract

The invention provides an immediate sewage disposal device of a ship propeller thruster and belongs to the technical field of ship engine protection. The technical problem to be solved is to provide the immediate sewage disposal device of the ship propeller thruster, wherein cleaning is conducted when a propeller is wound by water plants or fishing nets; the propeller is released; loads of the propeller are reduced; and normal work of the propeller is maintained. The adopted technical scheme is characterized in that a guide cylinder movably sleeves a rotation shaft of the propeller; a push-pull device is connected to one end of the guide cylinder located inside a ship body; at least three cutter bases are disposed on an installation ring of a current disk through circumferential radiation; the installation ring sleeves the rotation shaft of the propeller; a concave groove and a convex groove which are matched and used to prevent axial motion of the installation ring are disposed on contact faces of the rotation shaft and the installation ring; a cutter groove is formed in one side of each cutter base facing the propeller; a blade is in hinge connection in the cutter groove; a self-recovery spring is disposed on a cutter shaft of the blade; the cutter shaft is connected to one end of the guide cylinder by a pull rope; and the connection point between the pull rope and the cutter shaft is closest to the propeller when the blade is located inside the cutter groove.

Description

technical field [0001] The invention relates to an instant cleaning device for propeller propellers of ships, which belongs to the technical field of marine turbine protection, and in particular relates to a protection device for propellers. Background technique [0002] Ship propeller is a key component of submarine and ship navigation. Usually the ship propeller is coaxially installed at one end of the rotating shaft, the rotating shaft is supported by a slewing bearing fixed at the lower end of the hull, and the other end of the rotating shaft is connected with the driving device fixed on the hull. The propeller and the control system of the rudder mechanism work together to push the ship forward and change direction. However, the existing ship propellers are all arranged at the rear of the hull, and most of the propellers are exposed. During the working process, they are often entangled by weeds and fishing nets, and the rotating load is increased, and the entanglement ...
