Embodiment
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings.
With reference to Fig. 1 to Fig. 5, after oar of the invention energy recycle device it is main by by helicoid power generation blade 1, the whirlpool cap 4 that disappears,
Planetary gearbox 8, speed regulator 5, generator 12, transformer 14 etc. are constituted.Behind propeller for vessels, pacify before rudder
A TRT with two spiral blades 1 is filled, the two spiral blades can sufficiently absorb propeller tail
Rotating energy in stream, so as to which with certain rotary speed rotation, rotation of the power generation blade with moving axis of rotation passes through tooth
Rotating speed is brought up to generator rated speed by roller box, and cutting magnetic induction line produces electric current.The whirlpool cap 4 that disappears of this device, in propeller
Dead astern, reduces the water flow spaces that pressure value is relatively low after propeller, reduces the generation of whirlpool after propeller, absorb part
Rotating energy, makes tail flow field more stablize.Helicoid power generation blade.The whirlpool cap that disappears is arranged on the dead astern of propeller shaft and coaxial.
Power generation blade structure is made up of helicoid power generation blade 1 and cylindrical columns 2.Power generation blade is designed to helicoid
One is the energy lost after the recovery oar for having reached maximal efficiency in order to fully absorb the rotating energy in propeller wake field；
Two be helicoid form power generation blade produce the power along captain direction it is smaller, do not interfere with the propulsive efficiency of ship.Hair
Electric blade 1 is connected by connecting shaft 3 with speed regulator 5.The effect of speed regulator 5 is to stabilize rotary speed.Speed regulator 5 and low speed
Axle 6 is connected, and brake 7 is housed between slow-speed shaft 6 and planetary gear accelerating chamber 8, brake 7 can be in special common, humman feelings condition (example
Such as arrive port, turn to, device damage etc.) under locked slow-speed shaft brake 6, the effect of planetary gear accelerating chamber 8 is that rotating speed is improved
To generator rated speed, planetary gear accelerating chamber 8 is connected with high speed shaft 9, and high speed shaft 9 passes through shaft coupling 10 and generator shaft 11
It is connected, generator 12 produces electric current by the cutting magnetic induction line of generator shaft 11, and electric current flows to transformer 14 through wire 13, through transformation
Electric current afterwards flows to power device by wire.
The whirlpool cap 5 that disappears be arranged on propeller dead astern and and propeller coaxial, when ship's navigation, the rear meeting of propeller
A low-pressure area is formed, and easily forms whirlpool, the whirlpool cap that disappears can cut down this region and reduce the formation of whirlpool, energy is reduced
Loss.
The control principle of resistance-controllable ship rudder is：
(1) this device is arranged on the dead astern of propeller for vessels, and with propeller coaxial, rudder for ship is fixed on by base 16
Interior, power generation blade is located at the front of rudder.When ship's navigation, propeller rotation, so as to cause wake flow to rotate, in the wake flow of rotation
Substantial amounts of energy is contained, helicoid electricity generation impeller 1 can sufficiently utilize these energy in tail flow field, form torque, lead to
Crossing after speed regulator 5 is adjusted stably drives slow-speed shaft 6 to rotate, and brake 7 (such as, to port, can be turned to, device in special common, humman feelings condition
Damage etc.) under locked slow-speed shaft brake 7, generator rated speed can bring up to rotating speed by planetary gearbox 8,
Planetary gear accelerating chamber 8 is connected with high speed shaft 9, and high speed shaft 9 is connected by shaft coupling 10 with generator shaft 11, and generator shaft 11 is cut
Cutting magnetic induction line makes generator 12 produce electric current, and electric current is transmitted to after transformer 14 by wire 13 and carries out transformation, supplied again after transformation
It should be used to ship equipment, collector ring 15 is the effect of containing electric wire.
(2) the whirlpool cap 5 that disappears of the invention is arranged on the dead astern of propeller, and is coaxial therewith, when ship's navigation, spiral
The rear of oar can form a low-pressure area, and easily form whirlpool, and the whirlpool cap that disappears can make the relatively low current of pressure value after propeller
Region is reduced, and is reduced the generation of whirlpool after propeller, is absorbed part rotating energy, tail flow field is more stablized, and reduces energy
Loss.
To sum up, the present invention is energy regenerating TRT after a kind of oar.It is that a kind of propeller for vessels wake energy is reclaimed
Using device, mainly including power generation blade, speed-changing gear box, speed regulator and the part of generator four.Behind propeller, rudder
One TRT is above installed, because the wake flow of propeller has the energy of rotation, power generation blade can in screw current
To rotate.Acceleration, deceleration, steering due to ship etc. cause the wake flow of propeller unstable, so as to cause the rotation of power generation blade
Rotary speed can change, so plus a speed adjusting gear rotating speed is kept stable, then install speed-changing gear box additional rotating speed improved
To generator rated speed, then it is connected to again on generator, for electrical power generators.Thus TRT electricity energy can
Lived on ship, in terms of work.The whirlpool cap that disappears of this device, in the dead astern of propeller hub cap, makes pressure value after propeller
Relatively low water flow spaces are reduced, and are reduced the generation of whirlpool after propeller, are absorbed part rotating energy, make tail flow field more steady
It is fixed.The characteristics of energy regenerating generating device structure is simple after this oar, energy regenerating effect is good, it is latent in surface vessel and submarine in the future
There is good actual application prospect on device.
