Description
Technical field
The utility model belongs to power generation with marine energy field, more particularly to a kind of ocean power generating device and its power generation with marine energy
Water-leakage protecting device.
Background technology
Ocean energy (including tide energy, marine tidal-current energy, wave energy, energy by ocean current) refers to the energy of seawater flowing, as renewable
The energy, rich reserves are widely distributed, have fabulous DEVELOPMENT PROSPECT and value.The Land use systems of ocean energy mainly generate electricity, its
Operation principle is similar with wind-power electricity generation, i.e., by energy conversion device, the mechanical energy of seawater is converted into electric energy.Specifically,
The sea washes hydraulic turbine first, mechanical energy of the hydraulic turbine by the energy conversion of current for rotation, then the hydraulic turbine is by machinery biography
Dynamic system drives electrical power generators, is ultimately converted to electric energy.
Energy worsening shortages now, greenhouse effects getting worse, energy needs low-carbon, so wind energy, ocean energy etc. are clear
The clean energy is the developing direction of future source of energy.But the generating equipment of these present clean energy resourcies, except wind energy utilization comparative maturity
Outside, the utilization of ocean energy is also all in the starting stage, without general and ripe equipment.Because environment is complicated in ocean, therefore
Ocean power generating device can be more than the number that in general other TRTs need repairing, and cause maintenance cost to remain high.
Be generally used for the two kinds of generators that have of power generation with marine energy, one kind is trunnion axis hydrogenerator, its diameter parallel in
Horizontal plane, another kind are vertical axis hydrogenerators, and its axis is perpendicular to horizontal plane.Trunnion axis hydrogenerator is all due to it
Electrical equipment (including vane rotor, generator, gear-box, gearbox etc.) under water, therefore for the sealing of whole body
Property require it is very high.Particularly the junction of vane rotor and gear-box using sealing ring, it is necessary to be sealed.Sealing ring due to
Aging relaxation problem be present, in order to ensure the sealing property of sealing ring, at least to change once within every 3 years.Needed when replacing
Stop the operation of whole ocean power generating device.In order to install new sealing ring, some other elements will also be carried out accordingly
Remove and reinstall, this considerably increases difficulty is changed, improve maintenance cost.
Especially, due to maintenance personal often can not be checked in the sea sealing ring whether aging and sealing whether jail
Lean on, therefore the time to be changed of sealing ring can not be known exactly.In order to avoid current are penetrated into the trunnion axis hydraulic turbine
The damage for causing the trunnion axis hydraulic turbine is understood in portion, and for the sake of insurance, sealing ring just needs more even without aging, annual even half a year
Change.Stopping is needed to lead to not produce income due to being generated electricity when maintenance, and maintenance operations need to consume not
Small manpower and materials, frequently maintain and huge obstruction is brought to the commercial operation of power generation with marine energy.
In addition, the gear-box being connected with generator needs to change machine oil, and TRT after used a period of time
The bearing used is also required to change machine oil, so the maintenance and maintenance of trunnion axis hydrogenerator are more difficult, cost is higher.Cause
This, even if the generating efficiency of trunnion axis hydrogenerator is higher than vertical axis hydrogenerator, but trunnion axis hydrogenerator business
Change still extremely difficult.
With the increase of depth in dampening, pressure gradually increases.Because the pressure outside generating set can be far longer than inside
Pressure, therefore external water stream is easy to penetrate into inside generating set so as to damage generating set.For amplification generator group
Compressive property and sealing property, the sealing of intensity and structure to generator unit shell has higher requirement, and has
A little common sealing rings can not meet the seal request at deep-sea at all, it is necessary to special sealing ring, so as to cause production cost
It is soaring,；On the other hand, in order to increase the compressive property of generating set and sealing property, the volume of generating set is needed into one
Step reduces all close setting of all elements (gearbox, actuated element, generator etc.) so that in generating set, so adds
Friction between element, it greatly affected the efficiency of generating set.
Because existing ocean power generating device can not solve the problems, such as to be fully sealed, existing ocean power generating device exists
Depth of water direction generally all only sets a hydrogenerator to avoid pressure at deep water from causing very much sealing difficult greatly.However, so
Ocean energy at deep water can not be made full use of.
On the other hand, because marine tidal-current energy is generated electricity using the trend of ocean.Along with flood tide and ebb tide, the side of trend
To can change.Traditional most of trunnion axis hydrogenerator cannot all rotate, and cause marine tidal-current energy generator can only profit
Generated electricity with flood tide or ebb tide, generating efficiency is extremely low.Existing technical staff is in order to make full use of caused by flood tide and ebb tide
Energy, selection two sets of electricity generation systems of installation.The impeller of a set of electricity generation system is towards flood tide direction, the impeller of another set of electricity generation system
Towards ebb tide direction.Although seeming energy caused by flood tide and ebb tide all fully to be utilized, in flood tide or ebb tide, begin
A set of electricity generation system is had eventually to leave unused.Increase a set of electricity generation system and make it that production cost is double, and caused electric energy power carries
The increase of farsighted too late cost, this greatly limits the popularization of ocean power generating device and utilization.
