In prior art, the tolerance clearance portion of rudder for ship between tubulose rudder bearer and rudder blade is provided with hermetically-sealed construction, enter in rudder blade to stop the foreign material such as extraneous water, sand, and hermetically-sealed construction is not set between rudder stock and tubulose rudder bearer, between rudder stock and rudder blade, this makes the fluid in rudder blade easily to enter between rudder stock and tubulose rudder bearer gap and gap between rudder stock and rudder blade, when depositing between tolerance clearance in fluid, the problems such as the dismounting difficulty of rudder stock when fitting surface damage, rudder stock rotation alerting ability variation, maintenance can be caused.
Meanwhile, at present along with the rise of international oil price, how to reduce the energy consumption of boats and ships, the economic benefit improving boats and ships also becomes the important subject causing industry.And found by research, there is an obvious meiobar in the rear, center of screw propeller promoting boats and ships, the current in this region are very disorderly and have eddy current, and this part current can not play progradation to boats and ships, can reduce capacity usage ratio and the economic benefit of boats and ships.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of internal sealed rudder for ship that can reduce power consumption, to solve between existing rudder stock and tubulose rudder bearer, not arrange hermetically-sealed construction between rudder stock and rudder blade, easily there is the problems such as the dismounting difficulty of rudder stock when fitting surface damage, rudder stock rotation alerting ability variation, maintenance; And solve the problem of propeller center rear turbulent flow to boats and ships energy ezpenditure.
The utility model can reduce the internal sealed rudder for ship of power consumption, comprise rudder blade, rudder stock and support the tubulose rudder bearer of rudder stock, the round table-like lower end of described rudder stock is inserted in rudder blade, also comprise the hermetically-sealed construction of tolerance clearance between sealed tubular rudder bearer and rudder stock, described hermetically-sealed construction comprises the flange rubber sheet that is enclosed within outside rudder stock and flange rubber sheet is fixed on the pressing plate on tubulose rudder bearer, and described pressing plate is fixedly connected with tubulose rudder bearer by screw;
Also comprise and be arranged on rudder stock lower end in order to seal the seal ring of tolerance clearance between rudder stock and rudder blade;
Described rudder blade is just provided with rudder ball in the leading edge of propeller center, and described rudder ball is column, and the front end arcwall face of rudder ball has a sharp apex.
Further, described rudder ball also comprises the fusiformis rear along rudder blade horizontally set.
Further, described rudder blade is made up of shell and the cross wall be welded in the enclosure and vertical clapboard, and described cross wall and vertical clapboard are provided with oilhole.
Further, the lower end of described rudder stock has also been threaded nut, and the end face of described nut is sealed on the end of tolerance clearance between rudder stock and rudder blade; The end face of described rudder stock is also fixed with rudder stock lid by screw, and the side sealing label of described rudder stock cap seal lid is on the side of nut.
The beneficial effects of the utility model:
1, the utility model can reduce the internal sealed rudder for ship of power consumption, originally it by arranging hermetically-sealed construction between rudder blade and rudder stock, between tubulose rudder bearer and rudder stock, thus the fluid in rudder blade can be stoped to enter rudder stock and the tolerance clearance between rudder blade and tubulose rudder bearer, the dirt in fluid can be avoided to damage fitting surface, and avoid greasy dirt to cause rudder stock to rotate the problem such as alerting ability variation and maintenance dismounting difficulty.
2, the utility model can reduce the internal sealed rudder for ship of power consumption, it is by arranging the rudder ball of column, rudder ball prevents current to enter propeller center Background Region, thus the very large turbulent flow eliminating this part region, turbulent flow power consumption is low, power consumption when can reduce ship's navigation, the economic benefit of boats and ships of improving.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model can reduce the internal sealed rudder for ship of power consumption;
Fig. 2 is the enlarged view in P portion in Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
As depicted in figs. 1 and 2, the present embodiment can reduce the internal sealed rudder for ship of power consumption, comprise rudder blade 1, rudder stock 2 and support the tubulose rudder bearer 3 of rudder stock, the round table-like lower end of described rudder stock is inserted in rudder blade, also comprise the hermetically-sealed construction of tolerance clearance between sealed tubular rudder bearer and rudder stock, described hermetically-sealed construction comprises the flange rubber sheet 4 be enclosed within outside rudder stock and the pressing plate 5 be fixed on by flange rubber sheet on tubulose rudder bearer, and described pressing plate is fixedly connected with tubulose rudder bearer by screw 6;
Also comprise and be arranged on rudder stock lower end in order to seal the seal ring 7 of tolerance clearance between rudder stock and rudder blade;
Described rudder blade is just provided with rudder ball 8 in the leading edge of propeller center, and described rudder ball is column, and the front end arcwall face of rudder ball has a sharp apex 9.
The present embodiment can reduce the internal sealed rudder for ship of power consumption, originally it by arranging hermetically-sealed construction between rudder blade and rudder stock, between tubulose rudder bearer and rudder stock, thus the fluid in rudder blade can be stoped to enter rudder stock and the tolerance clearance between rudder blade and tubulose rudder bearer, the dirt in fluid can be avoided to damage fitting surface, and avoid greasy dirt to cause rudder stock to rotate the problem such as alerting ability variation and maintenance dismounting difficulty.
