Abstract
The invention relates to the technical field of the power drive device of a ship, in particular to an anti-wind propeller device, which comprises a streamline support, a stern shaft, a paddle drum and propeller blades, wherein the stern shaft is fixed into the streamline support through a bearing; one end of the stern shaft is connected with an internal combustion engine output shaft, and the other end of the stern shaft is connected with the paddle drum. The anti-wind propeller device is characterized in that the back face of at least one propeller blade is provided with a strip anti-wind cutter, and cutting edges of the cutters face to the tangent directions of the propeller blades; the anti-wind cutters are parallel to the axis of the paddle drum, so that the resistance of the anti-wind cutters is the minimum in rotation. The winding articles are cut automatically by means of the rotation of the propeller, the anti-wind propeller device has the advantages of simple structure, convenience in installation, complete cutting and the like, and all kinds of accidents or faults caused by the fact that a propeller shaft is wound are effectively prevented.
Description
Technical field
The present invention relates to the Power Drive Unit technical field of boats and ships, specifically a kind of winding-proof type propeller arrangement of easy for installation, use safety.
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 junction of hull is provided with ship stern pipe or beauty's frame, transmission shaft carrying screws rotates with the navigation driving boats and ships, during navigation, screw propeller oar drum and the groove between ship stern pipe or beauty's frame and screw propeller oar drum are 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 that a kind of structure is simple, easy to process, the winding-proof type propeller arrangement of use safety.
The present invention can be reached 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 fixed in beauty's frame through bearing, 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 the back side of at least 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, and resistance when rotating to make it is minimum.
Stern tube shaft cover between beauty's frame of the present invention and propeller has protecting jacket, and protecting jacket 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 is simple that it has structure, sends out dress convenience, cuts the advantages such as thorough, effectively prevent all kinds of accident or fault that cause because prop shaft is wound.
Accompanying drawing explanation
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 fixed in beauty's frame 1 through bearing, one end of stern tube shaft 2 is connected with internal combustion engine output shaft, stern tube shaft 2 other end is connected with slurry drum 3, the structure of above-mentioned each component part and the interconnected relationship between them same as the prior art, this does not repeat, the invention is characterized in that the back side of at least 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, resistance when rotating to make it is minimum, in addition, stern tube shaft cover between beauty's frame of the present invention and propeller has protecting jacket, protecting jacket 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 is simple that it has structure, send out dress convenient, cut the advantages such as thorough, effectively prevent all kinds of accident or fault that cause because prop shaft is wound.
