With rack gear B14, rack gear A13 meshing gear A10, rack gear B14 meshing gear B12, gear A 10 and gear B 12 are connected on axis 19,
Gear A 10 and 19 junction of axis are equipped with mono-directional overrun clutch A9, gear B 12 and 19 junction of axis be equipped with mono-directional overrun from
Clutch B11, axis 19 are fixedly connected with the input shaft of speed increaser 15, and the output shaft of speed increaser 15 connects rotor power generation by shaft coupling 16
Machine 17, speed increaser 15 are bolted on connecting plate 18.
The sidewall bottom of two racks 1 is equipped with magnet assembly between the bottom opposite with 4 two side plates of bluff body bracket, uses
Nonlinear restoring force is provided in moving for bluff body 5.
Magnet assembly includes single permanent magnet A7, and permanent magnet A7 is fixed in the opposite both side plate sidewall bottom of bluff body bracket 4,
Two 1 sidewall bottoms of rack are affixed to be connected with multiple permanent magnet B8 vertically side by side, and permanent magnet A7 is opposite with permanent magnet B8, permanent magnet
There is spacing between A7 and permanent magnet B8, spacing is adjustable, can produce nonlinear magnetism effect between single permanent magnet A7 and permanent magnet B8
Power.
The number of permanent magnet B8 is 3 or 4.
Limit assembly include each rack 1 lateral wall on be respectively mounted the linear guide 2 of one group of vertical direction, for preventing
During driving bluff body bracket 4 to move up and down Caton occurs for bluff body 3.
A kind of multistable galloping fluid dynamic energy power generator of the invention, since bluff body 3 is by gravity, spring 6 is in
Tensional state, spring 6 store elastic potential energy, and power when being flowed through due to 3 self gravity of bluff body and fluid to bluff body 3 makes spring 6
It stretches, when no fluid passes through or fluid velocity slows down, by the elastic potential energy of spring 6, bluff body 3 can restore position, thus
So that bluff body 3 drives bluff body bracket 4 back and forth to move up and down；In the two sides of bluff body 3, the lower part of bluff body bracket 4 is equipped with 3 or 4
The magnetic repulsion or magnetic attraction generated between strong magnetic-type permanent magnet B8, permanent magnet A7 and 3 or 4 permanent magnet B8 is bluff body fortune
It is dynamic that nonlinear restoring force is provided, rack gear A13 and rack gear B14 is housed on bluff body bracket 4, rack gear A13 is engaged with gear A 10, rack gear
B14 is engaged with gear B 12, and mono-directional overrun clutch A9 is opposite with the operative orientation of mono-directional overrun clutch B11；When bluff body 3 to
When upper movement, rack gear A13 drives gear A10 and mono-directional overrun clutch A9 rotation, due to the work of mono-directional overrun clutch B11
With the rotary motion of gear B 12 is not transferred to axis 19, so that gear A 10 is single with moving axis 19, speed increaser 15 and rotor generator 17
Direction rotation；When bluff body 3 moves downward, rack gear B14 drive gear B12 rotation, at this time gear A 10 dally, gear B 12 by
The rotary motion of gear B 12 is passed to axis 19, speed increaser 15 and rotor generator 17, to make by mono-directional overrun clutch B11
Always one direction rotates rotor generator, and generates electricity.
In order to guarantee that from liquid corrosion, highstrenghtpiston is can be used in gear and rack teeth mechanism, speed increaser, rotor generator etc.
Or stainless steel plate is sealed, and only leaves bluff body exposure in a fluid.
A kind of multistable galloping fluid dynamic energy power generator of the invention, the specific working principle is as follows:
The fluid force of interleaved can be applied to the surface of solids when fluid flows through solid, so that reciprocal fortune occurs for solid
It is dynamic, and the reciprocating motion of solid changes fluid flow state, and then changes the fluid force for acting on the surface of solids, this fluid with consolidate
The phenomenon that body interacts referred to as Flow vibration, as shown in figure 5, ratio can be carried out based on Flow vibration generating device structure size
Miniaturization, has the characteristics that at low cost, applied widely.
Multistable galloping fluid dynamic energy power generator of the invention is placed on and flows to vertical direction, i.e. bluff body with fluid
3 axis is vertical with the direction that liquid flows, and when the flow velocity of fluid reaches certain speed, fluid impact bluff body 3 is produced in fluid
Raw alternating whirlpool makes bluff body 3 that bluff body bracket 4 be driven to vibrate up and down, and rack gear A13 and rack gear B14 is housed, when blunt on bluff body bracket 4
When body 3 moves upwards, bluff body bracket 4 moves upwards simultaneously with carry-over bar A13 and rack gear B14, due to mono-directional overrun clutch B11
For operative orientation with mono-directional overrun clutch A9 just on the contrary, when rack gear A13 is moved upwards, rack gear A13 drives gear A10 and list
It is rotated to freewheel clutch A9, due to the effect of mono-directional overrun clutch B11, the rotary motion of gear B 12 is not transferred to axis 19,
To which gear A 10 is rotated with moving axis 19, speed increaser 15 and 17 one direction of rotor generator.When bluff body 3 moves downward, rack gear
B14 drives gear B12 rotation, and gear A 10 dallies at this time, and gear B 12 is by mono-directional overrun clutch B11, by the rotation of gear B 12
Transhipment is dynamic to pass to axis 19, speed increaser 15 and rotor generator 17, to make rotor generator, one direction is rotated always.
When bluff body 3 generates when the vibrations are up and down on the direction perpendicular to incoming flow, when using 3 permanent magnet B8, due to list
There are nonlinear magnetism active force between a permanent magnet A7 and 3 permanent magnet B8, bluff body 3 generates the potential-energy function of Non-Linear Vibration such as
Shown in Fig. 6 (a), such as spherula A in Fig. 6 (a) of bluff body 3, moves back and forth between position 1 and position 2 and is formed in motion process
It substantially moving, to pass through 2 potential barriers and 3 potential wells, dotted line indicates the middle position of spherula A motion process in Fig. 6 (a), with
There is no the vibration of nonlinear magnetism active force to compare, under nonlinear magnetism active force the moving displacement of bluff body 3, speed amplitude increase
Greatly to increase generating efficiency；
When using 4 permanent magnet B8, bluff body 3 is generated shown in potential-energy function such as Fig. 6 (b) of Non-Linear Vibration, bluff body 3
Motion process is similar to Fig. 6 (a).Three-stable state and four steady-state vibration modes may be selected according to the Reynolds number of incoming flow, to improve the stream
Cause the generating efficiency of vibration generating device.
