Abstract
The utility model discloses a prevent device of screw and rudder blade collision damage, including the propeller shaft, the propeller shaft passes the shaft hub, the end of propeller shaft is equipped with the screw, the upside installation tail-stock of shaft hub, the lower extreme rudder stock of shaft hub, the rear side of screw is equipped with the rudder blade, and the rudder stock is buckled to the downside of rudder blade. According to the device for preventing the propeller and the rudder blade from being damaged by collision, the rudder carrier is arranged below the propeller and the rudder blade, so that the effect of protecting the propeller and the rudder blade when a ship touches hard objects or runs shallow in the process of sailing is achieved.
Description
Technical Field
The utility model belongs to the technical field of screw and rudder blade protection, concretely relates to prevent device of screw and rudder blade collision damage.
Background
A ship is a vehicle which can be sailed or moored in a water area for transportation or operation, and has different technical performances, equipment and structural types according to different use requirements. The ship propeller can be divided into a propeller ship, a water jet propulsion ship, a paddle ship, a flat-pitch ship and the like, and the air propeller is only used for a few hovercraft; according to the position of the engine room, a tail-engine type ship (the engine room is arranged at the tail part of the ship), a middle-engine type ship and a middle-tail engine type ship; according to the structural materials of the ship body, a steel ship, an aluminum alloy ship, a wood ship, a steel wire mesh cement ship, a glass fiber reinforced plastic ship, a rubber boat, a mixed structure ship and the like are available. The propeller propulsion has the widest application range and the most stable structure, but the existing propeller ship does not have a protection mechanism in the propulsion process, and the propeller and the rudder blade are easily damaged when the ship touches hard objects or runs shallow in the navigation process.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a prevent device of screw and rudder blade collision damage to the problem of proposing among the above-mentioned background art is solved.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a prevent device of screw and rudder blade collision damage, includes the propeller shaft, the propeller shaft passes the shaft hub, the end of propeller shaft is equipped with the screw, the upside installation tail-stock of shaft hub, the lower extreme rudder stock of shaft hub, the rear side of screw is equipped with the rudder blade, and the rudder stock is buckled to the downside of rudder blade.
Preferably, the end of the rudder stock is provided with a lantern ring.
The utility model discloses a technological effect and advantage: according to the device for preventing the propeller and the rudder blade from being damaged by collision, the rudder carrier is arranged below the propeller and the rudder blade, so that the effect of protecting the propeller and the rudder blade when a ship touches hard objects or runs shallow in the process of sailing is achieved.

FIG. 2 is a schematic view of the structure of the present invention in the direction A;
fig. 3 is an enlarged schematic structural diagram of the position B of the present invention.
In the figure: 1. a propeller shaft; 2. a hub; 3. a propeller; 4. a rudder blade; 5. a tail pillar; 6. a rudder carrier.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model provides a prevent device that screw and rudder blade collision damage as shown in fig. 1-3, including propeller shaft 1, propeller shaft 1 passes shaft hub 2, the end of propeller shaft 1 is equipped with screw 3, shaft hub 2's upside installation caudal peduncle 5, shaft hub 2's lower extreme rudder stock 6, the rear side of screw 3 is equipped with rudder blade 4, and rudder stock 6 buckles to the downside of rudder blade 4, rudder stock 6's end is equipped with the lantern ring, and the lantern ring can insert corresponding rudder blade dead lever, and convenient when not using is fixed to rudder blade 4.
The rudder stock 6 is arranged below the propeller 3 and the rudder blade 4, so that the propeller 3 and the rudder blade 4 are protected when the ship touches hard objects or runs shallow in the process of sailing.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
