Abstract
The invention relates to a mute electrical ship which comprises a ship body and a power source arranged in the ship body and used for driving a motor to operate. The mute electrical ship is characterized by also comprising a submarine ship thruster, the submarine ship thruster is fixed at the bottom of the ship body and is immersed in water, and the submarine ship thruster comprises the submarine motor fixed at the bottom of the ship body and a propeller tightly connected with an output shaft of the motor. The invention has compact and streamlined structure, easy manufacturing and low cost; because the output shaft of the motor is directly connected with the propeller without using other indirect transmission components, the power transmission efficiency is ideal. Because the motor of the mute electrical ship is arranged in water, people in the surface ship can not hear obvious noise, and the motor is applicable to the manufacturing of small pleasure ships for leisure tours.
Description
One. technical field
The invention belongs to the electromechanical engineering technical field, particularly relate to the improvement of electric ship.
Two. background technology
The electric ship of operation all is to adopt power drives setting electrical motor aboard ship at present, make the screw propeller rotation that links to each other with electrical motor again, and then propulsion of vessels advances.
In addition, application number 200810048319.6, name is called " full electric ship of charging accumulator of wind, light and electricity composite energy resource " disclosed innovation and creation, comprise hull, the front portion of hull is provided with control desk, the rear portion is provided with electricpropulsion installation, battery pack is installed in the bottom of hull, control desk links to each other with electricpropulsion installation with storage battery respectively by cable, storage battery is connected with battery charger, battery charger is connected with bank electricity access device, is provided with solar panels and wind-driven generator at the top of hull, and they link to each other with battery pack by control desk.This invention adopts the mode of accumulate to solve the synchroneity problem of generating distribution electricity consumption, though reach asynchronous effect, increases the time and the chance of comprehensive application nature clean energy resource.The navigation or the Shi Douke that suspends utilize wind energy; Not only can be used for propulsion of ship, and can be used for other current consumer; Form honourable electric three's combination and mutual supplement with each other's advantages simultaneously, on total system, improve function and efficient, both can obtain the cheap energy, continuity that again can assurance work operation.But because setting electrical motor aboard ship causes running noises very big.
Application number 200710135390.3, name is called " electromotion ship transportation system " disclosed innovation and creation, comprise electric power system and electric ship, electric power system comprises the lead that is used for transmission current and the several supporters that are used to support described lead of flow path direction setting along the river; The power take-off implement that electric ship comprises hull, is positioned at the electrical motor of this hull, is connected with electrical motor, supporter is arranged on river course middle part, electric ship also comprise be arranged on the hull both sides be used for electric current is introduced at least one pair of pantograph in the electrical motor from described lead.Though this invention can be saved the capital construction cost of building electric power system greatly, and safe and reliable to operation, economical and energy saving.But be equally the electrical motor setting aboard ship, running noises is also very big.
More than the electric ship of these forms all be complex structure, manufacture difficulty is big.And, the current innovation and creation with the disclosed electric ship of above document on the market have a common weak point, that is exactly that power machine or electrical motor all are arranged in the boats and ships, spiral pushing device is arranged under water, hear the motor operation noise that is difficult to eliminate on the one hand aboard ship, this small-sized pleasure-boat for some Leisure Tours is a shortcoming of it's a pity, because apart from long and drive mechanism complexity, rubbing to increase, power machine or electrical motor and screw propeller also make power bring loss on the other hand.People wish to design and manufacture noise-free electric ship very much, but regrettably up to this point, still do not have this noise-free electric ship selling on the market.
Three. summary of the invention
The objective of the invention is to manufacture and design a kind of quiet electric ship, to overcome present electric ship complex structure, manufacture difficulty is big, simultaneously because power machine or electrical motor all are arranged in the boats and ships, spiral pushing device is arranged under water, hears aboard ship that therefore the motor operation noise and drive mechanism complexity, the friction increase that are difficult to eliminate make power bring the shortcoming of loss.
The object of the present invention is achieved like this: a kind of quiet electric ship, comprise hull 11, be arranged at the power supply that hull 11 interior also driving motors 5 turn round, it is characterized by: also have marine propeller 12 under water, described marine propeller under water 12 is fixed in the bottom of hull 11 and is dipped in the water, under water marine propeller 12 comprise electrical motor 5 in the bottom water that is fixed in hull 11, with the screw propellers 3 that the output shaft 4 of electrical motor 5 closely links to each other, described electrical motor 5 has waterproof outer cover.
The cross-sectional plane of cylindrical shell 1 is circle or rectangle or triangle or rhombus or polygon.
The top of cylindrical shell 1 can make the fork 7 of its swing when being fixed with twisting.
Suitable axis, the outside of cylindrical shell 1 direction is fixed with the secondary rudder plate 9 more than.
Take the present invention of above measure, the compact conformation smoothness, easy to manufacture, with low cost, the output shaft of electrical motor directly joins with screw propeller, does not have other indirect drive parts, so the unusual ideal of power transmission efficiency.Electrical motor of the present invention is arranged under water, therefore can not hear tangible motor operation noise in above water craft, very is fit to make the pleasure-boat of Leisure Tour.
