Using triangle, rectangle or other shapes.Two sets of horizontal shaft water-turbines are installed on swivel mount using side-by-side arrangement.It is described
The deflector of bias current device rotates appropriate angle according to incoming situation and ocean current is adjusted.
When ocean current flows through the tidal current energy generating equipment, whole swivel mount and the hydraulic turbine are subject to drag effect and around rotation
Axis rotate, stable state is reached after swivel mount goes to equilbrium position, when ocean current flows through bias current device deflector can to ocean current into
Row is optimized and revised, and changes flow direction and the distribution of ocean current so that it more uniformly flows to turbine blade, blade rotation from
And drive generator to rotate, marine tidal-current energy is converted into electric energy.
Compared with prior art, the beneficial effects of the invention are as follows：This new tidal current energy generating system includes two sets vertically
Axis turbine power generating device, bias current device, swivel mount and seabed pedestal.Horizontal shaft water-turbine power generator includes vertical axis water

Embodiment
Fig. 1,2,3 show a kind of structure chart of new tidal current energy generating system.In figure, this new marine tidal-current energy power generation system
System includes two sets of horizontal shaft water-turbine power generator, bias current device, swivel mount and seabed pedestal.Horizontal shaft water-turbine power generation dress
Put and include turbine blade 2, mounting bracket 1 and shaft 3, water including horizontal shaft water-turbine and generator, horizontal shaft water-turbine
Turbine blade 2 is fixedly connected by mounting bracket 1 with shaft 3, and shaft 3 sets and is arranged on by bearing in support platform 4, positioned at branch
Generator in the empty cabin 10 of 4 top of support platform is driven by shaft 3.The support platform 4 of swivel mount is fixedly connected with rotation axis 7.
Seabed pedestal is fixedly connected with multiple spud legs 6 using connecting elements 5, the taper on the bullet of 7 lower end of rotation axis and a spud leg 6
Hole is engaged.Using torsionspring 8, two deflectors 9, angle is arranged on the both sides of rotation axis 7 to bias current device on request.Lifting
System is arranged between spud leg 6 and rotation axis 7.
Above-mentioned technical proposal operation principle is as follows：The tidal current energy generating system is arranged in seabed by modes such as piling, when
Ocean current along any direction flow to the electricity generation system when, it is uneven to act on power on turbine blade 2 and swivel mount, so as to produce
A raw deflection torque causes swivel mount to be rotated around rotation axis, so as to adjust the relative position of power generator and incoming.Work as water wheels
After the stress of machine blade 2 and swivel mount reaches balance, rotatable portion is not rotated further around rotation axis 7 so as to reach a kind of flat
Weighing apparatus state.After swivel mount goes to equilbrium position, ocean current first flows through deflector 9 and flows to turbine blade 2 again.When ocean current is by inclined
During flowing plate 9, different angles can be rotated according to different incoming situation deflectors 9 incoming is adjusted, including direction of flow
And distribution situation, so that ocean current is more reasonable, effectively flows to the hydraulic turbine, and then reduce the startup of horizontal shaft water-turbine
Flow velocity.Horizontal shaft water-turbine blade 2 rotates under incoming effect, so as to drive generator to rotate, marine tidal-current energy is converted to electric energy.
For convenience of being overhauled to power generator, swivel mount and spud leg 6 use separation design, and swivel mount is filled by lifting
Realization is put to rise and recycle.Lifting gear includes cable, capstan winch and locking device, when needing that power generator is overhauled
When, locking device release swivel mount, swivel mount rises to the water surface under buoyancy and cable tension effect.To rotation after maintenance
Frame is recycled, and under cable traction effect and buoyancy, swivel mount is pulled original installation site.For convenience of swivel mount
Recycling fixation is carried out, at 6 locking device of spud leg and 7 relevant position of rotation axis is using the bullet design to match each other.When
When swivel mount will be recycled to spud leg 6, the cone in rotation axis 7 can conveniently be inserted into taper matched in locking device
Kong Zhong, so as to guide swivel mount to be docked with locking device.Easily power generator and the hydraulic turbine can be determined by jacking system
Phase carries out maintaining, while avoids the cumbersome mode that whole system is promoted to the water surface.
Two sets of horizontal shaft water-turbines being mounted side by side incoming effect under rotation direction on the contrary, each rotate the hydraulic turbine
The current driven can produce beneficial effect to another hydraulic turbine again, so that rotating speed of the hydraulic turbine under the flow velocity is improved, into
And improve the electricity generation efficiency of power generator.
