Abstract
The utility model belongs to the Power Drive Unit technical field of boats and ships, relates to the antiwind cutter sweep of a kind of propeller for vessels.Comprise screw propeller, tailing axle, ship stern pipe, be provided with the main carriage rotated with tailing axle in the end of the tailing axle near ship stern pipe, described main carriage is along the circumferential direction evenly provided with multiple main blade; The tail end of described ship stern pipe is provided with secondary knife rest, described secondary knife rest is provided with an auxiliary-blade, and two surveys of described main blade and auxiliary-blade are respectively arranged with blade.The both sides of described main blade and auxiliary-blade are respectively the symmetrically arranged curved blade caved inward.This device practicality is good and optimize the dynamic balance property of screw propeller.
Description
Technical field
The utility model belongs to the Power Drive Unit technical field of boats and ships, relates to the antiwind cutter sweep of a kind of propeller for vessels.
Background technology
Boats and ships during water-area navigation operation, due to some wastes such as rope ubiquitous in water, fishing nets, usually run into the situation that screw propeller is wound in coastal, inland river etc.After this type of situation occurs, screw propeller resistance increases, time serious screw propeller stuck, shut down, not only have impact on the normal operation of boats and ships, the serious accident that ship even can be caused to ruin people die.
Current; the method that boats and ships generally use installs a seal cover cap at the tailing axle place of boats and ships; cover completely by propeller drive shaft exposed part, the key position that generation is wound around is protected, thus reduces the possibility of foreign matter winding screw oar; there is drawback in these preventive; once screw propeller place et out of order, even if some glitch, disembarkation just had to by boats and ships; could repair after being taken off by seal closure, repairing is difficult and the cycle is long.
Chinese Patent Application No. 201210426899.4 discloses " a kind of antiwind ships and light boats actuating device ", it has installed a cutting rod cutter on the propeller hub of screw propeller, and bar cutter is along with screw propeller high speed rotating, create moment, destroy the kinetic balance of screw propeller, bring huge hidden danger to ship's navigation.Meanwhile, propeller boss installs serration cutting tool additional, need to redesign marine rear shaft part, and the boats and ships used in delivered to be installed this type of cutter be also very difficulty, and can not safety of navigation be ensured.Chinese Patent Application No. 200720089454.6 discloses " a kind of rotovator anti-cutter shaft wind of secondary cutter ", it comprises auxiliary-blade, supporting plate, wear-resistant axle sleeve etc., by the relative motion of major and minor blade, twister is effectively cut, if but use on boats and ships, also to consider factors, if whether firm etc. screw propeller positive and negative rotation, auxiliary-blade to be arranged on tailing axle.
Summary of the invention
Technical problem to be solved in the utility model is, provide a kind of practicality good, the antiwind cutter sweep of the dynamically balanced propeller for vessels of screw propeller can not be destroyed.
The antiwind cutter sweep of propeller for vessels of the present utility model, comprises screw propeller, tailing axle, ship stern pipe, and be provided with the main carriage rotated with tailing axle in the end of the tailing axle near ship stern pipe, described main carriage is along the circumferential direction evenly provided with multiple main blade; The tail end of described ship stern pipe is provided with secondary knife rest, described secondary knife rest is provided with an auxiliary-blade parallel with main blade; Two surveys of described main blade and auxiliary-blade are respectively arranged with blade.
The blade of the both sides of described main blade and auxiliary-blade is the symmetrically arranged curved blade caved inward.
The tip edge of described main blade is also provided with cutting teeth.
Roller is provided with between described main carriage and secondary knife rest.
Described main carriage is fixed on tailing axle by an elastic ring.
The utility model has the advantage of: 1. multiple main blade is circumferentially evenly arranged on the main carriage be positioned on tailing axle, and be provided with elastic ring and be used for cushioning effect, optimize screw propeller dynamic balance property.2. elastic ring also plays and prevents main carriage from sliding and protect the effect of tailing axle.3. the both sides of main blade and auxiliary-blade are respectively the symmetrically arranged curved blade caved inward, and no matter tailing axle rotates forward or reversion, and can cut twister, cut by the mode sheared, cutting effect is better.
Accompanying drawing explanation
Fig. 1 is Facad structure schematic diagram of the present utility model;
Fig. 2 is construction profile schematic diagram of the present utility model.
Detailed description of the invention
below in conjunction with the drawings and specific embodiments, the utility model is described further
As shown in the figure: the antiwind cutter sweep of a kind of propeller for vessels, comprise screw propeller 1, tailing axle 2, ship stern pipe 3, be provided with the main carriage 4 rotated with tailing axle 2 in the end of the tailing axle 2 near ship stern pipe 3, described main carriage 4 is along the circumferential direction evenly provided with 3 main blades 5; The tail end of described ship stern pipe 3 is provided with secondary knife rest 6, described secondary knife rest 6 is provided with an auxiliary-blade 7 parallel with main blade 5; Two surveys of described main blade 5 and auxiliary-blade 7 are respectively arranged with blade.
The blade of the both sides of described main blade 5 and auxiliary-blade 7 is the symmetrically arranged curved blade caved inward.
The tip edge of described main blade 5 is also provided with cutting teeth 8.
Roller 10 is provided with between described main carriage 4 and secondary knife rest 6.
Described main carriage 4 is fixed on tailing axle 2 by an elastic ring 9, and the material of described elastic ring 9 is anti-slip rubber.
When main blade 5 rotates with tailing axle 2, with auxiliary-blade 7 in shear effect, when rope or fishing net are between main blade 5 and auxiliary-blade 7, then by property cut, the booster action of the cutting teeth 8 of the tip edge of main blade 5 can be added, antiwind better effects if.
