It can further be cut by the steel knife on shield side wall, under double action, be realized to ship in use,
Avoid propeller not snarled by water plant, and the setting of cleaning pipe, water section intracavitary in shield can be extracted out, and by water from
Water outlet is flowed out and is cleaned to the side of shield, so that the water plant blended can be quickly far from hull, into one
The stability for improving propeller and using of step, while also improving the service life of propeller.
In the protective device of above-mentioned propeller, the cleaning pipe includes connecting tube and sparge pipe, the connecting tube with
Shield connection, the sparge pipe are connect with connecting tube, and the sparge pipe is in flared, and heavy caliber one end of the sparge pipe is
Water outlet.
In the protective device of above-mentioned propeller, there are three the blade is set, three blades along partition length side
To setting.
In the protective device of above-mentioned propeller, the steel knife is positioned close to the side of bottom plate.
In the protective device of above-mentioned propeller, the partition is equipped with eight, and eight partitions are circumferentially uniform along bottom plate
Distribution.
In the protective device of above-mentioned propeller, width of the partition close to the center of circle of bottom plate is less than partition the bottom of far from
The width in the center of circle of plate.
Compared with prior art, the protective device of this propeller has the advantage that：The setting of cleaning pipe, can will be in shield
Intracavitary water section extraction, and water is flowed out from water outlet and the side of shield is cleaned, so that blended
Water plant can further improve the stability that propeller uses quickly far from hull.
