Abstract
The invention discloses a sawtooth propeller. The sawtooth propeller comprises a tail shaft and a screw propeller, wherein the screw propeller is arranged on the tail shaft at the bottom of a stern; paddle sawteeth are arranged on the front edge of each paddle of the screw propeller; propeller hub sawteeth are arranged on the edge of a propeller hub of the screw propeller. After the design is adopted, the tail shaft rotates to drive the screw propeller to rotate at a high speed, the paddle sawteeth on the front edge of each paddle of the screw propeller and the propeller hub sawteeth on the edge of the propeller hub can form effective cutting force to cut and smash foreign matters (such as waterweeds, fishing nets and cables) which are possibly wound on the tail shaft and the screw propeller, and thus a winding phenomenon is avoided. According to the sawtooth propeller, the structure of the screw propeller of a ship body is transformed, under the condition that the propelling performance of the screw propeller is not influenced, and the capability of preventing the foreign matters from winding is improved, so that a ship with the sawtooth propeller can be driven in a complex water area.
Description
technical fieldthe present invention relates to the propelling unit that in water, ship is used, relate in particular to a kind of sawtooth propelling unit.
background technologywhen boats and ships navigate by water in water, the screw propeller of boats and ships is easy to be wound around by the floating debris in water (as pasture and water, fishing net, hawser etc.), has influence on the normal work of screw propeller.Cause sometimes boats and ships to run out of steam, cause a serious accident, so, need to a kind ofly can prevent that foreign material from causing the propelling unit of winding to screw propeller.
summary of the inventionthe invention provides a kind of can effectively anti-sealing in foreign material screw propeller is caused to the sawtooth propelling unit of winding.
For achieving the above object, sawtooth propelling unit of the present invention comprises tailing axle and screw propeller, and described screw propeller is arranged on the tailing axle of stern bottom, and the leading edge of each blade of screw propeller is provided with blade sawtooth, and the propeller hub edge of screw propeller is provided with propeller hub sawtooth.Adopt above design, tailing axle rotarily drive screw propeller high speed rotating, the blade sawtooth of propeller blade leading edge and the propeller hub sawtooth at propeller hub edge can form actv. cutting force, foreign matter (as pasture and water, fishing net, the cable etc.) cut-out that may be wrapped in possibility water on screw propeller and tailing axle is smashed, thereby avoided the generation being wound around.
Sawtooth propelling unit of the present invention also comprises streamlined reefer housing and bracing frame, described streamlined reefer housing is hollow cartridge type, streamlined reefer housing vertical section is frustum, streamlined reefer housing is fixed on stern bottom by bracing frame, tailing axle is entered by the less side of cross-sectional plane on streamlined reefer housing, the side that on streamlined reefer housing, cross-sectional plane is larger is open, and the screw propeller on tailing axle is positioned at the space of streamlined reefer housing hollow.Adopt above design, most foreign matter can be blocked in outside by diversed cover, can not remove screw propeller, therefore can guarantee that screw propeller is not subject to larger or hard foreign matter directly to collide injury, and people and animals are also not easy because directly touching screw propeller part injured.The special profile of streamlined reefer housing can guarantee that current are under the promotion of screw propeller, by opening one side spray of streamlined reefer housing, is shot out, and has improved tractive performance.In addition, streamlined reefer housing can actv. reduces the noise of screw propeller, even if be provided with sawtooth on screw propeller and propeller hub like this, in the process of running, also can not produce obvious noise.
The side that streamlined reefer housing cross-sectional plane of the present invention is less is connected with the aft pivot cap of hollow, tailing axle from aft pivot cap by and enter in streamlined reefer housing.Aft pivot cap is not subject to winding and the collision injury of foreign matter in water for the protection of the transmission shaft part that is exposed to hull outside.
Sawtooth propelling unit of the present invention also comprises cutting blade, and cutting blade is fixed on bracing frame, and the cutting edge of cutting blade is towards fore direction.One end of each cutting blade of the present invention is connected on the bracing frame of hull bottom, and the other end connects on aft pivot cap.Hull is in motion process, and cutting blade forms cutting force forward, when touching foreign matter, can cut off foreign matter in water by actv., its fragmentation is scatter, and can not impact the screw propeller at rear portion.
Compared with prior art, sawtooth propelling unit of the present invention, by the transformation on hull propeller arrangement, in the situation that not affecting propulsion quality, has improved the ability that anti-foreign matter is wound around, and making to have equipped this angle of rake ship can travel in complex water areas.
