According to the invention, the pod and a rudder are combined into a whole, modules such as the propeller and the pod are reserved, and a complicated rotating device is omitted; while the propulsion performance of a ship is guaranteed, the driveability of the ship is realized by the rudder. Therefore, major advantages of a full-rotating podded propulsor that the arrangement is flexible, the vibration is small, the noise is low, and the like are reserved, the defects of the full-rotating podded propulsor that the structure is complicated and the price is high are overcome, and the wider application of the rudder-pod ship electric propulsion system to more ship types is hopeful.
Description
Technical field
The present invention relates to a kind of watercraft electric propulsion system, specifically, be a kind of rudder gondola watercraft electric propulsion system, belong to propulsion of ship technical field.
Background technology
In propulsion of ship field, traditional marine propuision system employing screw propeller coordinates with rudder, and as shown in Figure 2, hull afterbody is provided with the screw propeller of diesel, and rudderpost drives rudder blade carry out rotating thus change the navigation direction of ship.
Existing ripe full circle swinging gondola propulsion system at present, as shown in Figure 1, this system is primarily of module compositions such as screw propeller, gondola, turning gears 10, and propulsion electric machine is installed in the gondola of sealing, is connected with screw propeller by prop shaft.Relative to traditional diesel propulsion device, full circle swinging PODDED PROPULSOR have flexible arrangement, road-holding property good, vibrate the advantages such as little, noise is low.As the important component part of all-direction propeller, turning gear 10 plays key player, and it can realize propelling unit in horizontal surface, do 360 degree of revolutions, makes propelling unit send the thrust of any direction, thus realize the maneuvering performance of boats and ships, eliminate the rudder in normal shipboard.But turning gear 10 needs to arrange a large amount of core of a cable, and revolution action need be carried out under water, complicated slip ring structure, hermetically-sealed construction and control system certainly will be needed, this has been doomed all-direction propeller complex structure, expensive, to be difficult to accept by the lower ship type (as bulge carrier) of cost, and once turning gear et out of order, by direct threatens vessel safety, these unfavorable factors limit the further genralrlization of all-direction propeller.
Summary of the invention
The technical issues that need to address of the present invention are: existing full circle swinging gondola propulsion system, its turning gear needs to arrange a large amount of core of a cable, and revolution action need be carried out under water, complicated slip ring structure, hermetically-sealed construction and control system certainly will be needed, this has been doomed all-direction propeller complex structure, expensive, to be difficult to accept by the lower ship type (as bulge carrier) of cost, and once turning gear et out of order, by direct threatens vessel safety, these unfavorable factors limit the further genralrlization of all-direction propeller.
The present invention takes following technical scheme:
A kind of rudder gondola watercraft electric propulsion system, comprises rudder blade 1, rudder horn 2, gondola 3, electrical motor 4, screw propeller 6; Described rudder horn 2 is installed on stern, and is connected with rudder blade 1, and described rudder horn 2 is horizontally disposed with gondola 3, and described electrical motor 4 is arranged in gondola 3, and screw propeller 6 is connected by prop shaft 9 with electrical motor 4; Described electrical motor 4 receives power supply from hull and control signal, drives screw propeller.
Screw propeller 6 provides thrust power for boats and ships, and rudder blade 1 freely can rotate to realize Ship Maneuverability around rudderpost 8, thus eliminates the turning gear of full circle swinging gondola rotary system.
Gondola and rudder unite two into one by the technical program, remain the module such as screw propeller, gondola, eliminate complicated turning gear, while guarantee propulsion of ship performance, realize Ship Maneuverability by rudder.Thus both remained full circle swinging PODDED PROPULSOR flexible arrangement, vibrate most advantages such as little, noise is low, overcome again full circle swinging PODDED PROPULSOR complex structure, expensive deficiency, be expected to be applied in more ship types.
Further, described gondola 3 is arranged on the bottom of rudder horn 2.
Further, also comprise seal ring 5, propeller hub cap 7, described seal ring 5 is for the sealing of prop shaft 9, and propeller hub cap 7 is fixing for screw propeller 6.
Beneficial effect of the present invention is:
1) remain the module such as screw propeller, gondola, eliminate complicated turning gear, but remain full circle swinging PODDED PROPULSOR flexible arrangement, vibrate most advantages such as little, noise is low.
2) overcome full circle swinging PODDED PROPULSOR complex structure, expensive deficiency, be expected to be applied in more ship types.
3) failure rate is low, trouble-shooting is convenient than full circle swinging gondola propulsion system, improves the safety performance of boats and ships.
4) applicability is wide, has the application prospect extensively promoted.

Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the present invention is further described.
See Fig. 3, the invention provides a set of rudder gondola watercraft electric propulsion system, this system adopts electric power as the energy, rudder, oar, motor is integrated in one, can realizes propulsion of ship and manoeuvre of ship function simultaneously.
As shown in Figure 3, whole system is primarily of parts compositions such as rudder blade 1, rudder horn 2, gondola 3, electrical motor 4, screw propellers 6, and each parts relationship is as follows:
Whole rudder horn 2 is installed on stern, establishes gondola at its bottom position, motor arrangement in gondola, by external sea water cooling.Retain the rudder blade below rudderpost line of centers 8 rear and gondola, screw propeller is connected by prop shaft 9 with electrical motor, and seal ring 5 and propeller hub cap 7 are for sealing and fix.By the cable between electrical motor and hull, electrical motor can receive power supply from hull and control signal, drives screw propeller.
Rudder gondola watercraft electric propulsion system can independently use as rudder oar, also can combinationally use with conventional diesel propulsion system, forming mixing to turning oar propulsion system, realizing more energy-conservation object.
During specific works, screw propeller provides thrust power for hull, and rudder blade 1 freely can rotate to realize Ship Maneuverability around rudderpost 8, thus eliminates the turning gear of full circle swinging gondola rotary system.
The electric power system of hull interior and control system provide power supply and control signal for the electrical motor in gondola, and drive the screw propeller be attached thereto, screw propeller provides thrust, and thrust is passed to hull via rudder horn, promotes boats and ships and advances.Ship maneuverability can be realized by the rudder in rudder towed bird system, concrete control method and common rudder control method similar.
Gondola and rudder unite two into one by the present invention, remain the module such as screw propeller, gondola, eliminate complicated turning gear, while guarantee propulsion of ship performance, realize Ship Maneuverability by rudder.Thus both remained full circle swinging PODDED PROPULSOR flexible arrangement, vibrate most advantages such as little, noise is low, overcome again full circle swinging PODDED PROPULSOR complex structure, expensive deficiency, be expected to be applied in more ship types.
