Abstract
The utility model relates to a suspension rear-rudder semi-submerged paddle propulsion apparatus, which is characterized in that the device is installed at the tail of a ship body in suspending through a tail plate 16 and a rudder bracket 7, wherein, the tail plate is fixed on a stern sealed plate 14 of the ship body, and a fixed rudder bracket 7 and a shaft sleeve 13 are installed on the tail plate; a ship power shaft passing through the shaft sleeve is connected with a propeller 8; the shaft sleeve and the rudder bracket are connected into a whole through a shaft bracket 9, making the propeller higher than a ship bottom 12 and form a semi-submerged shape; a hydraulic oil cylinder 1 which is operated and controlled by a hydraulic steering engine is installed on the rudder bracket 7 through a hydraulic oil cylinder seat 2. The utility model has the advantages that the arrangement of a carrier of the ship body is not influenced; because the rubber is placed backwards, the effect of the rudder is obvious; the propulsion of the semi-submerged paddle makes the ship body have low draught; the rotary vibration of the ship body and the noise are reduced; the propulsion efficiency is raised. The utility model is particularly applied to high speed ships.
Description
The utility model relates to the rudder and the slurry propelling unit of boats and ships, and the rearmounted rudder half of particularly a kind of suspension type is dived and starched propelling unit.
The propelling unit of boats and ships of the prior art designs afterbody alow mostly, and this results in hand cramps for the master layout of boats and ships, and particularly high speed vessel is all very difficult in order to obtain higher propulsion coefficient, low noise, low vibration and shallow draft.
The purpose of this utility model provides a kind of boats and ships that can make that are specially adapted to that high speed vessel uses and obtains the rearmounted rudder half of higher propulsion coefficient, low noise, low vibration and the light-draft suspension type slurry propelling unit of diving.
Above-mentioned purpose of the present utility model is to realize by such technical scheme, be the rearmounted rudder half of a kind of suspension type slurry propelling unit of diving, comprise propeller, rudder blade, by hydraulic sterring engine handle control hydraulic ram, rudder stock, with the tiller of hydraulic ram and rudder stock top attachment; It is characterized in that: device hangs by tailgate and rudder support and is installed in the hull afterbody, wherein tailgate is fixed on the stern transom plate of hull, install and fix rudder support and axle sleeve on it, the ship power axle passes axle sleeve and connects propeller, bracing strut combines as a whole axle sleeve and rudder support, and making propeller be higher than hull bottom is half latent shape; The hydraulic ram of being handled control by hydraulic sterring engine is installed on the rudder support by the hydraulic ram seat, and rudder stock passes the front end of rudder support vertically downward, and by upper and lower bearings.
Said structure of the present utility model can further specify by the embodiment that accompanying drawing provides.
The utility model has following accompanying drawing:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the structural representation of tailgate 16;
Accompanying drawing 3 is the birds-eye view of accompanying drawing 1.
Referring to accompanying drawing: the rearmounted rudder half of the suspension type among the figure slurry propelling unit of diving, comprise propeller 8, rudder blade 11, by hydraulic sterring engine handle control hydraulic ram 1, rudder stock 10, with the tiller 15 of hydraulic ram and rudder stock top attachment; It is characterized in that: device hangs by tailgate 16 and rudder support 7 and is installed in the hull afterbody, wherein tailgate is fixed on the stern transom plate 14 of hull, install and fix rudder support 7 and axle sleeve 13 on it, the ship power axle passes axle sleeve and connects propeller 8, bracing strut 9 combines as a whole axle sleeve and rudder support, and making propeller be higher than hull bottom 12 is half latent shape; The hydraulic ram 1 of being handled control by hydraulic sterring engine is installed on the rudder support 7 by hydraulic ram seat 2, and the rudder stock that connects with rudder blade passes the front end of rudder support vertically downward, and by upper and lower bearings.
An illustrated embodiments of the present utility model is: device adopts the two slurry of Twin Rudders structure, wherein, the hydraulic ram 1 of being handled control by hydraulic sterring engine is installed on the one rudder support, fix a connection arm 17 with its transmission at the rudder stock top, a fixing end of rudder connecting rod 18 on it, the other end of rudder connecting rod connects with the tiller on another rudder stock top.When rotating under a rudder blade is being handled control by hydraulic sterring engine hydraulic ram 1 drives, just next plays rotation to the another rudder in the drive of rudder connecting rod.
In the above-described embodiments, pass the position of rudder support front end, reinforce by upper and lower bracket 4,5 at rudder stock.
The good effect that the utility model produces owing to described structure is very significant, that is:
1. do not affect the hull carrier and arrange, stayed bigger space to aircraft window;
2. employing rear-rudder, steerage is fairly obvious, and Ship Controling provides the safety can when giving complicated navigation channel The assurance of leaning on;
3. adopt half latent slurry to advance, make hull obtain the religion shallow draft, suitable navigation channel range extension;
4. whole propelling unit is suspended on the hull afterbody, and the rotation of hull and noise are reduced greatly; And propulsion coefficient improves greatly, obtains the higher speed of a ship or plane, has also improved efficient of operation or the like.
The utility model is specially adapted to high speed vessel.
