It is well known that the propulsion plant of ship typically uses propeller, propeller is made up of propeller hub and propeller blade, spiral
Oar is connected through stern tube shaft with the output shaft of main frame, and stern tube shaft is connected through bearing, bearing block and sealing device with hull, and hull is corresponding
Propeller junction is provided with ship stern pipe or beauty's frame, and stern tube shaft drives propeller rotation to drive the navigation of ship, during navigation, spiral shell
The region revolved between oar propeller hub and ship stern pipe or beauty's frame is usually wound by debris such as the floating object in water, fishing net, hawsers, shadow
The normal work of propeller is rung, damage propeller, ship is also resulted in sometimes and runs out of steam, cause a serious accident, at present, in order to
Solving the problems, such as to be wound, existing technology is typically all to install cutter on the propeller hub or ship stern pipe of propeller, due to
Power transmission shaft is typically all naked to be exposed on the external, and the debris that can not be cut is wrapped on exposed power transmission shaft, because power transmission shaft is smooth, debris
Power transmission shaft and ship stern pipe junction can be slipped into along power transmission shaft, will result in after a time between power transmission shaft and ship stern pipe
Frictional force increases, and influences the rotation of power transmission shaft, because cutter is parallel with power transmission shaft, therefore floating object, fishing net and hawser etc. sometimes
Cutter can be wound and wrapped up, influenceed the normal work of propeller, also result in ship sometimes and run out of steam, cause a serious accident,
Particularly existing cutter are typically all partial cut, do not ensure that the whole power transmission shaft position of protection.
The content of the invention
Present invention aim to address above-mentioned the deficiencies in the prior art, there is provided one kind protection propeller, protection drive shaft, cuts
Cut the hull of the good anti-propeller winding of effect.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of hull of anti-propeller winding, provided with hull, the bottom of hull is provided with ship stern pipe, and transmission is provided with ship stern pipe
Axle, one end of power transmission shaft is stretched into ship stern pipe to be connected with hull dynamical system, and the other end of power transmission shaft stretches out ship stern pipe
It is connected with the axle sleeve in the middle part of propeller, it is characterised in that described propeller shaft is put provided with strip-cutting knife, described ship
Oceangoing ship stern pipe side is provided with annular groove, and one end of strip-cutting knife is connected with propeller axle sleeve, the other end of strip-cutting knife
Provided with sliding block, described sliding block is put in annular groove, and strip-cutting knife is driven along annular by the rotation of propeller axle sleeve
Groove rotates, and then protects power transmission shaft not wound.
Below ship stern pipe of the present invention bar shaped reticular lamina, one end warp of described bar shaped reticular lamina are provided with through support
Support is connected with ship stern pipe, and the other end of bar shaped reticular lamina extends the lower section of propeller and stretches out propeller part, in ship
During body navigates by water, bar shaped reticular lamina by the pasture and water below propeller, pull rope barrier in the lower section of bar shaped reticular lamina, further
Prevent from being wound by propeller.
The width of bar shaped reticular lamina of the present invention is more than the diameter of propeller, ensures that bar shaped reticular lamina wraps spiral
Oar, propeller is prevented to wind lower section debris.
The present invention is provided with annular because described propeller shaft is put provided with strip-cutting knife, described ship stern pipe side
Groove, one end of strip-cutting knife are connected with propeller axle sleeve, and the other end of strip-cutting knife is provided with sliding block, described sliding block
Put in annular groove, drive strip-cutting knife to be rotated along annular groove by the rotation of propeller axle sleeve, and then protect and pass
Moving axis is not wound, and bar shaped reticular lamina, one end warp of described bar shaped reticular lamina are provided with through support below described ship stern pipe
Support is connected with ship stern pipe, and the other end of bar shaped reticular lamina extends the lower section of propeller and stretches out propeller part, in ship
During body navigates by water, bar shaped reticular lamina by the pasture and water below propeller, pull rope barrier in the lower section of bar shaped reticular lamina, further
Prevent from being wound by propeller, the width of described bar shaped reticular lamina is more than the diameter of propeller, ensures that bar shaped reticular lamina wraps
Propeller, prevent propeller from winding lower section debris, have the advantages that to protect propeller, protection drive shaft, good cutting effect.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
Enter an explanation to the present invention below in conjunction with the accompanying drawings：
As shown in drawings, a kind of hull of anti-propeller winding, provided with hull 1, the bottom of hull 1 is provided with ship stern pipe 2, ship
Power transmission shaft 3 is provided with stern pipe 2, one end of power transmission shaft 3 is stretched into ship stern pipe 2 to be connected with hull dynamical system, power transmission shaft 3
The other end stretches out ship stern pipe 2 and is connected with the axle sleeve 9 at the middle part of propeller 8, it is characterised in that is set on described propeller axle sleeve 9
There is strip-cutting knife 4, the described side of ship stern pipe 2 is provided with annular groove 5, one end and the propeller axle sleeve 6 of strip-cutting knife 4
It is connected, the other end of strip-cutting knife 4 is provided with sliding block 6, and described sliding block 6 is put in annular groove 5, passes through propeller axle sleeve
3 rotation drives strip-cutting knife 4 to be rotated along annular groove 5, and then protects power transmission shaft 3 not wound, described ship stern
The lower section of pipe 2 is provided with bar shaped reticular lamina 7 through support 10, and one end of described bar shaped reticular lamina 7 is connected through support 10 with ship stern pipe 2
Connecing, the other end of bar shaped reticular lamina 7 extends the lower section of propeller 8 and stretches out propeller part, during hull navigates by water, bar
Shape reticular lamina 7 by the pasture and water below propeller, pull rope barrier in the lower section of bar shaped reticular lamina 7, further prevent from being twined by propeller
Around the width of described bar shaped reticular lamina 7 is more than the diameter of propeller 8, ensures that bar shaped reticular lamina wraps propeller 8, prevents
Propeller winding lower section debris.
In the use of the present invention, because propeller axle sleeve 9 directly passes through end of the strip-cutting knife 4 directly with ship stern pipe 2
Face is slidably connected, and ensures absolute not exposed of power transmission shaft, due to twister is in winding while the more twine the more tight, will directly twine
On sub- strip-cutting knife 4, it is cut twister, simultaneously because the lower section of ship stern pipe 2 is direct provided with bar shaped reticular lamina 7
The rear of propeller is extended, ensure that propeller is not contacted with the weeds of lower section, reduces the possibility of propeller winding, is protected
Propeller is protected, because described propeller axle sleeve 9 is provided with strip-cutting knife 4, the described side of ship stern pipe 2 is provided with the present invention
