Abstract
The utility model relates to the technical field of power drive devices of ships, in particular to an anti-entanglement propeller device. The anti-entanglement propeller device comprises a stern tube, a stern shaft, a propeller drum and propeller blades. The stern shaft is fixed in the stern tube through a bearing. One end of the stern shaft is connected with an output shaft of an internal combustion engine. The other end of the stern shaft is connected with the propeller drum. The anti-entanglement propeller device is characterized in that a strip-shaped anti-entanglement cutting knife is arranged on the reverse side of at least one propeller blade, and a knife edge of the anti-entanglement cutting knife faces the tangential direction of the corresponding propeller blade; the axis of the anti-entanglement cutting knife is parallel to the axis of the propeller drum so that resistance of the anti-entanglement cutting knife can be minimized in the rotation process. According to the anti-entanglement propeller device, entanglement can be automatically cut through rotation of a propeller, the anti-entanglement propeller device has the advantages of being simple in structure, convenient to install, thorough in cutting effect and the like, and various accidents or failures caused by the situation that a propeller shaft is entangled are effectively avoided.
Description
Technical field
The present invention relates to the Power Drive Unit technical field of boats and ships, specifically a kind of easy for installation, use safe winding-proof type propeller arrangement.
Background technology
As everyone knows, the propelling unit of boats and ships generally adopts screw propeller mode, screw propeller is made up of oar drum and screw blade, screw propeller is connected with the output shaft of engine through transmission shaft, transmission shaft is through bearing, bearing seat and sealing arrangement and be connected on hull, the corresponding screw propeller of hull junction is provided with ship stern pipe or beauty's frame, transmission shaft drives screw propeller to rotate to drive the navigation of boats and ships, when navigation, groove between screw propeller oar drum and ship stern pipe or beauty's frame and screw propeller oar drum is usually by the floating debris in water, fishing net, the windings such as hawser, affect the normal work of screw propeller, sometimes also can cause damaging screw propeller, boats and ships run out of steam, cause a serious accident.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, easy to process, use safe winding-proof type propeller arrangement.
The present invention can reach by following measure:
A kind of winding-proof type propeller arrangement, comprise beauty's frame, stern tube shaft, oar drum and screw blade, stern tube shaft is in bearing is fixed on beauty's frame, one end of stern tube shaft is connected with internal combustion engine output shaft, the stern tube shaft other end is connected with slurry drum, it is characterized in that at least the back side of a slice propeller blade is provided with the anti-tangle cutter of strip, the blade of anti-tangle cutter is towards the tangential direction of propeller blade.
Anti-tangle cutter of the present invention parallels with the axis of slurry drum, so that resistance minimum when its rotation.
Stern tube shaft cover between beauty's frame of the present invention and propeller has protecting jacket, and protecting jacket one side is connected with beauty's frame through bolt, and protecting jacket opposite side is at least provided with two symmetrical protruding blades.
The present invention utilizes the rotational automatic of screw propeller to cut twister, and it has simple in structure, sends out dress convenience, cuts the advantages such as thorough, has effectively prevented to be wound because of prop shaft all kinds of accidents or the fault that cause.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in the figure, a kind of winding-proof type propeller arrangement, comprise beauty's frame 1, stern tube shaft 2, oar drum 3 and screw blade 4, stern tube shaft 2 is in bearing is fixed on beauty's frame 1, one end of stern tube shaft 2 is connected with internal combustion engine output shaft, stern tube shaft 2 other ends are connected with slurry drum 3, the structure of above-mentioned each component part and the interconnected relationship between them are same as the prior art, this does not repeat, the invention is characterized in that at least the back side of a slice propeller blade 4 is provided with the anti-tangle cutter 5 of strip, the blade of anti-tangle cutter 5 is towards the tangential direction of propeller blade, anti-tangle cutter 5 of the present invention parallels with the axis of slurry drum, so that the resistance minimum in its when rotation, in addition, stern tube shaft cover between beauty's frame of the present invention and propeller has protecting jacket, protecting jacket one side is connected with beauty's frame through bolt, protecting jacket opposite side is at least provided with two symmetrical protruding blades, the present invention utilizes the rotational automatic of screw propeller to cut twister, it has simple in structure, send out dress convenient, cut the advantages such as thorough, effectively prevent to be wound because of prop shaft all kinds of accidents or the fault that cause.
