Anti-winding device for unmanned boat propeller propeller

Abstract

The invention discloses an anti-winding device of an unmanned boat propeller thruster. The anti-winding device comprises a rotary shaft; the left end of the rotary shaft and an external power output shaft are connected through a coupling, and four propellers are mounted at the right end of the outer side face of the rotary shaft at equal angles; an annular protrusion is arranged on the right sideof the outer side face of the rotary shaft, and protrusion positioning spiral insection is formed on the annular protrusion; a movable cutting pipe sleeves the rotary shaft, and embedded spiral insection is formed on the inner wall of the movable cutting pipe; and part of water suspended solids is blocked by a U-shaped shielding rod and a circular ring, left side cutting knives, arc-shaped knivesand right side cutting knives can move in a left-right reciprocating mode in the radial direction of the rotary shaft so as to cut the wound suspended solids, and power of left-right moving of the movable cutting pipe is only assisted by rotary motion of the rotary shaft. The anti-winding device of the unmanned boat propeller thruster is simple in structure, low in cost and good in clearing effecton the wound suspended solids, and thus normal navigation and production work of an unmanned boat are ensured.

Description

technical field [0001] The invention relates to the technical field of ship manufacturing, in particular to an anti-winding device for propeller propellers of unmanned ships. Background technique [0002] During the voyage of unmanned boats, the bottom of the hull often comes into contact with suspended matter in water such as aquatic plants, nets, and ropes. Under the action of the shape of the hull, these suspended matters quickly flow to the tail of the ship with the current and wind around the propeller. on the reel. The occurrence of entanglement incidents will affect the speed of the ship, and the resistance of the propeller will increase or even stall, causing the unmanned vessel to stop sailing, seriously affecting the normal navigation and production operations of the unmanned vessel. The usual treatment method for this accident is to suspend the voyage, arrange personnel to take a boat close to the faulty unmanned boat to manually remove the entanglement, or use o...

Problems solved by technology

The occurrence of entanglement incidents will affect the speed of the ship, and the resistance of the propeller will increase or even stall, causing the unmanned vessel to stop sailing, seriously affecting the normal navigation and production operations of the unmanned vessel

The usual treatment method for this accident is to suspend the voyage, arrange personnel to take a boat close to the faulty unmanned boat to manually remove the entanglement, or use other ships to pull the accident boat to the shore for treatment, which will affect the normal work of the unmanned boat
