Embodiment：
Below in conjunction with accompanying drawing, the present invention is described in further detail.
The general illustration for the TRT that the present invention is provided is as shown in figure 1, the technical scheme taken in figure is as follows：
Trunnion axis 1 is fixedly connected and is mutually perpendicular to vertical axis 2, and blade 3 can be waved with vertical axis 2 around trunnion axis 1
Motion；Meanwhile, blade 3 can do twist motion around vertical axis 2.Trunnion axis 1 has end 4 and end 5, its medial end portions 4 it is circumferential and
It is radially fixed, can axially movable, the mechanism such as end 5 and gearbox and generator is connected.Blade 3 under the driving to flow around
Trunnion axis 1 is swung, and now the kinetic energy of fluid is converted into the mechanical energy of Fig. 1 devices, and a portion mechanical energy is output as by end 5
Electric energy, a part of mechanical energy is reversed for driving blade 3 around vertical axis 2, and some mechanical energy storage is in spring 7.Deposit
The potential energy being stored in spring 7 is used to recover the position of blade 3, the mechanical energy that final conversion electric energy and driving blade 3 are reversed.It is overall next
See, the energy collected from fluid largely changes into electric energy and exported by end 5, sub-fraction is used for driving blade 3 around vertical
D-axis 2 is reversed.
6 be two bearings, for fixing trunnion axis 1.Spring 7 is fixedly connected with trunnion axis 1, for keeping flat when static
Weighing apparatus position, controls the amplitude of oscillating motion during motion.Gear 8 is fixedly connected with trunnion axis 1, and rack 9 is intermeshed with gear 8,
For the circumferential movement of gear 8 to be converted into linear motion.Piston in hydraulic cylinder 10 does to backhaul under the drive of gear 9
It is dynamic.Flexible pipe 11 is connected with hydraulic cylinder 10 with hydraulic push rod 13.Hydraulic push rod 13 is fixed on platform 12, for promoting blade 3 to make
Twist motion.
Blade movement schematic diagram is illustrated in figure 2,16 represent direction of flow, and 17 represent the direction of motion of blade and platform.
Streamwise is looked, and Fig. 2 (a) Leafs are acted on by the constraint of left side magnetic confinement device 14 while being flowed to the right side by arriving
Power and the direction shown in the direction of motion 17 of blade and platform is moved.When blade moves to the right extreme position with platform,
Blade is pushed into left side magnetic confinement device 14 by the hydraulic push rod 13 on the right around axle 2, such as Fig. 2 (b), and now blade is by fluid matasomatism
The direction of power changes and towards left side motion, when blade moves to left side extreme position with platform, the hydraulic push rod 13 on the left side will
Blade is pushed into the right magnetic confinement device 14 around axle 2, and so far blade 3, platform 12 and vertical axis 2 complete a cycle around trunnion axis 1
Swing.And so on, trunnion axis 1 does periodic rotation under the drive of blade 3, and trunnion axis 1 drives the engine shaft cycle
Property rotate, so as to export alternating current.
The operation principle of hydraulic mechanism is as shown in figure 3, trunnion axis 1 is moved with moving gear 8, and gear 8 is moved with carry-over bar 9,
Rack 9 drives first piston 19 and second piston 20 in hydraulic cylinder 10 to move.When first piston 19 and second piston 20 are
When being moved between one mouth of pipe 21 and second mouth of pipe 22, hydraulic oil is flowed back and forth by pipeline 18, now the hydraulic pressure in hydraulic cylinder 10
Oil will not drive hydraulic push rod 13 to move, and the position of 3 Relative vertical axle of blade 2 keeps constant.When second piston 20 move right it is super
When crossing second mouth of pipe 22, hydraulic cylinder 10 starts driving hydraulic push rod 13 and moved, and changes the angle of blade 3.The work that pipeline 18 is present
With being to make blade most of the time angle in a rolling period keep constant, only quickly change at peak swing and attack
Angle, it is such to be designed with beneficial to raising energy absorbing efficiency.
The present apparatus adapts to different speed of incoming flow by following scheme：
When speed of incoming flow is larger, by the axial movement back-moving spring 7 of end 4 so as to increase the rigidity of spring 7, and then
Limit the swing amplitudes of blade 3；Distance between first piston 19 and second piston 20 can also be reduced simultaneously so that blade is more
Reverse to change angle at big swing amplitudes；
When speed of incoming flow is smaller, pull-off spring 7, reduction rigidity, so that ensure that blade 3 can have larger swing amplitudes,
Enough energy driving blades 3 are reserved to reverse to change angle；Can also increase simultaneously first piston 19 and second piston 20 it
Between distance so that blade reverses to change angle at less swing amplitudes；
Flow velocity further reduces, the active force that fluid is applied on blade 3 be not enough to drive blade 3 reverse, in other words from
Energy also hour needed for the energy ratio blade twist gathered in fluid, the device can not export electric energy；Flow velocity definition now
For critical flow velocity, less than critical speed, the device is out of service, and electric energy could be exported higher than critical speed.
In addition, being moved again after fluid is static, because blade remains an angle of attack, mechanism can be in fluid velocity foot
Self-starting is realized when enough big.
