Specific embodiment
Fig. 1,2,3 show a kind of structure chart of tidal current energy generating system using guiding device.In figure, this marine tidal-current energy
Electricity generation system includes two sets of horizontal shaft water-turbine power generator, guiding device, swivel mount and seabed pedestal.Horizontal shaft water-turbine
Power generator includes horizontal shaft water-turbine and generator, and horizontal shaft water-turbine includes turbine blade 2, mounting rack 1 and turns
Axis 3, turbine blade 2 are fixedly connected by mounting rack 1 with shaft 3, and the setting of shaft 3 is arranged in support platform 4 by bearing,
Generator in the empty cabin 11 above support platform 4 is driven by shaft 3.The support platform 4 and rotary shaft 7 of swivel mount are fixed
Connection.Seabed pedestal is fixedly connected with multiple spud legs 6 using connecting elements 5, on the bullet of 7 lower end of rotary shaft and a spud leg 6
Bellmouth match (as shown in Figure 4), have an angular plate 8 in rotary shaft 7.Guiding device is led using torsionspring 9 two
8 two sides of angular plate of rotary shaft 7 are arranged in angle to flowing plate 10 as required.Jacking system is arranged between spud leg 6 and rotary shaft 7.
The length of deflector 10 is 1.17 times of 2 length of turbine blade, and the width of deflector 10 is the 0.12 of 10 length of deflector.
Fig. 5 shows the structure chart that deflector is connect with angular plate.The connection structure is respectively arranged at the both ends of deflector 10
One.For a connection structure, two second hinge casing 10a are fixedly connected on deflector 10, it is fixed on angular plate 8
Two corresponding first axle casing 8a are connected, the second hinge casing with pin shaft 12 from upper end above torsional spring 9
First axle casing 8a and second hinge casing 10a below 10a and first axle casing 8a, torsional spring 9 and torsional spring 9
Afterwards, split pin 12a is loaded onto 12 lower end of pin shaft.For torsional spring 9, spring upper end 9a is fixedly connected with angular plate 8, spring
Lower end 9b is fixedly connected with deflector 10, and so that deflector 10 is located at an initial position using a common position limiting structure.
Above-mentioned technical proposal working principle is as follows: the tidal current energy generating system is arranged in seabed by modes such as piling, when
When ocean current flows to the electricity generation system along any direction, the power acted on turbine blade 2 and swivel mount is uneven, to produce
A raw deflection torque rotates swivel mount around rotary shaft, so as to adjust the relative position of power generator and incoming flow, makes to get
It is parallel with device bilateral symmetry face to flow direction, at this point, turbine blade 2 and swivel mount reach equilibrium state, rotatable portion
It is not rotated further around rotary shaft 7.After swivel mount goes to equilbrium position, ocean current first flows through deflector 10 and flows to turbine blade 2 again,
Turbine blade 2 rotates under incoming flow effect, so that generator be driven to rotate, marine tidal-current energy is converted to electric energy.The work of deflector
With as shown in fig. 6, blade ring around 360 ° within the scope of have thrust region and Resistance Level.Thrust drives hydraulic turbine power generation, resistance resistance
The hydraulic turbine is hindered to generate electricity.The presence of deflector increases thrust region flow velocity, and the thrust that blade is subject to becomes larger, and water flow generates
Driving moment increase with it；Reduce Resistance Level flow velocity, resistance suffered by blade reduces, the obstruction that water flow generates
Torque also reduces therewith.Therefore, the total driving moment of the hydraulic turbine increases, so that its generating efficiency improves, while reducing its starting stream
Speed.
For convenience of overhauling to power generator, swivel mount and spud leg 6 use separation design, and swivel mount passes through lifting dress
Realization is set to rise and recycle.Lifting device includes cable, capstan winch and locking device, when needing to overhaul to power generator
When, locking device discharges swivel mount, and 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 corresponding position of rotary shaft is using the bullet design to match each other.When
When swivel mount will be recycled to spud leg 6, the cone in rotary shaft 7 can facilitate taper matched in insertion locking device
Kong Zhong, so that swivel mount be guided to dock with locking device.It is fixed to power generator and the hydraulic turbine to be convenient to by jacking system
Phase carries out maintenance, while avoiding 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 flow effect under rotation direction on the contrary, each rotation the hydraulic turbine
The water flow driven can generate beneficial effect to another hydraulic turbine again, so that revolving speed of the hydraulic turbine under the flow velocity is improved, into
And improve the electricity generation efficiency of power generator.
