Description
Technical field
The invention belongs to energy by ocean current power fields, and in particular to a kind of horizontal shaft ocean current energy generation is suitable for ocean current
The two-way incoming power generation of energy.
Background technology
In field of renewable energy, energy by ocean current is a kind of clean reproducible energy, and China's energy by ocean current rich reserves are opened
It is huge to send out Exploitative potential.Energy by ocean current has many advantages, such as that energy density is big, predictability is strong, horizontal shaft ocean current energy generation be by
Energy by ocean current is converted into the device of electric energy, and existing horizontal shaft ocean current energy generation is mostly unidirectional power generation, namely in unidirectional incoming
Promotion under generate electricity, be easier on unidirectional generation technology, but many landform tide bulge and falls in coastal waters, to improve generated energy, it is necessary to
Realize two-way power generation.And it is to carry out feather to blade to realize the controlling party rule of the two-way power generation of horizontal shaft ocean current energy generation
Control.The unidirectional power generator of energy by ocean current is spacing paddle device, and energy by ocean current bidirectional generating set is variable propeller pitch device.
The pulp distance varying mechanism of ocean current energy generator mainly has following functions：First, it can be driven by pulp distance varying mechanism
Dynamic blade rotates 180 ° to adapt to the variation of current direction around its reference line direction；Secondly, pulp distance varying mechanism can pass through rotation
Blade makes blade work under the best angle of attack, fully absorbs energy of ocean current, reaches best output power；In addition to this, exist
By severe sea condition ocean current overstep the extreme limit speed when, pulp distance varying mechanism makes blade off-target operating point, to catching blade
Power stability is obtained near rated power.
According to the difference of power part, existing pulp distance varying mechanism can be divided into electric pitch-changing driving and hydraulic variable-pitch
Driving, using the structure type of motor connection reduction box, hydraulic variable-pitch drives to be connected using hydraulic cylinder for electric pitch-changing driving
The structure type or hydraulic motor drive form of push rod.The two respectively has advantage and disadvantage, such as hydraulic variable-pitch in practical applications
Driving has many advantages, such as to transmit that torque is big, is convenient for centralized arrangement, and electric variable pitch driving be then not present it is non-linear, leak, bite
Phenomena such as.
But existing electric variable pitch spacing mechanism and the usual structure of hydraulic vane change spacing mechanism are more complicated, reliability is poor,
Entire pitch-variable system involves great expense, and overall robustness is poor.Pulp distance varying mechanism will in view of the problem of have：Seawater sealing is asked
Topic, i.e. sealing between blade and wheel hub；Bearing problem between blade and propeller hub；Oil feeding system, power supply system and detection paddle
The arrangement of the sensor of leaf position will avoid complexity；Motor, hydraulic motor, oil cylinder will account for larger space.Especially at sea occur
Failure, repairing is more difficult, will produce the larger cost of repairs.
Also there is the fixing oar bidirectional generating set for not showing two-way power generation by feather mode, structure is blade, master
Axis, gearbox, shaft coupling, generator, shaft coupling, gearbox, main shaft, blade are sequentially connected, and are equivalent to using two fixing oars
Unidirectional power generator（The two corresponds to different ocean currents and flows to）Tail portion and tail portion are docked, and only the two shares a generator,
A generator is omitted.But this fixing oar bidirectional generating set length is longer, integral rigidity is poor, and volume is larger, peace
It fills inconvenient to use.
