Abstract
The invention belongs to the field of renewable energy resources and relates to a novel wave energy power generation device which can collect wave energy and convert the wave energy into ocean currents in a pipeline so as to generate power by driving a turbine through the ocean currents. The turbine is directly placed in a water channel, and blades are driven to rotate through kinetic energy of sea water. The pitch angle can be automatically changed by the blades of the turbine so as to adapt to changes of the direction of the ocean currents in the pipeline, and therefore the starting performance of the turbine is improved, and the rotating direction of the turbine is not changed. The device is easy to construct, a power generator does not make contact with sea water, and the reliability is high; the shrinking water channel is used for collecting the wave energy and converting the wave energy into reciprocating ocean current energy in the vertical water channel; the power generator is directly driven through the passive self-pitch-changing turbine; the reliability and the converting efficiency are effectively improved; due to the fact that the power generator is placed on the shore and does not make contact with sea water, the power generator is convenient to maintain, and operating cost is reduced.
Description
Technical field
The invention belongs to field of renewable energy, relate to a kind of to assemble wave energy the ocean current that wave is converted in pipeline, utilize ocean current to drive the new-type wave energy TRT of turbine generation.
Background technology
The energy is the necessary requirement that the mankind depend on for existence and development, and the allowable exploitation of fossil energy gradually decreases, and the mankind can only Looking For Substitutions Of Oil.Wherein wave energy content is huge, has considerable DEVELOPMENT PROSPECT, but the exploitation of wave energy is still within conceptual phase, it is impossible to meet business-like requirement.Although the scientific and technological demonstrative project having wave energy in recent years is implemented, but technology immature, it is impossible to promote on a large scale.Oscillating water column wave power conversion technology is a kind of important wave energy development scheme, and it is the reciprocating motion of air the convert reciprocating motion of wave, promotes wheel rotation by the air stream of compression.This technology mostly uses air Wells turbine as wave energy converter, and this turbine is a kind of aerodynamic turbine, and energy could need to be utilized by turbine through two times transfer, and conversion efficiency is low.It is contemplated that propose a kind of brand-new wave-energy power generation mode.
Summary of the invention
It is an object of the invention to develop and a kind of can assemble wave energy the ocean current that wave is converted in pipeline, utilize ocean current to drive the new-type wave energy TRT of turbine generation.
Technical scheme:
Electromotor is arranged on the bank, do not contact sea water, it is to avoid the corrosion of sea water.Turbine is placed directly within water channel, utilizes the kinetic energy of sea water to drive blade to rotate.Turbine blade can change propeller pitch angle automatically, and the change of current direction in adaptation pipeline, thus improves the startability of turbine and direction of rotation is constant.
It is broadening formation that water channel is shunk on bank, and opening part is oval and be circular at turbine, and both have the biggest area ratio, and the water velocity at turbine is opening part several times.Wave pours in water channel from opening part, by the reciprocal ocean current being converted in vertical water channel after shrinking water channel.In order to prevent ratchel under extreme climate to be washed into water channel, water channel opening part to seabed keeps a segment distance and is vertical cross section.The bottom shrinking water channel is downward-sloping, which reduces the chance that silt is attached in water channel.
Turbine is placed in the centre position of water-head in vertical water channel, is connected by main shaft with generator amature.Vertical water channel top is fillet, so can ensure that ventilation road is smooth and easy, reduces ventilation noise.Ventilation road can ensure that vertical water channel is connected with outside atmosphere, it is to avoid affects the peak level of vertical water channel due to air compression when wave pours in vertical water channel.Electromotor is fixed on bank, utilizes straddle truck it to be sling together with turbine when needing repairing.Maintenance is carried out on bank, does not contact sea water, which decreases cost and the difficulty of maintenance.
Invention effect
The present invention constructs simply, and electromotor does not contacts with sea water, and reliability is high；Shrink water channel for converging wave energy the reciprocal energy by ocean current changing in vertical water channel；By passive from displacement turbine direct drive generator；It is effectively increased reliability and conversion efficiency；Owing to electromotor is placed on the bank, do not contact sea water, convenient maintenance, reduce operating cost.

Detailed description of the invention
Electromotor 2 is connected with straddle truck 1 by side arm 3 on the bank.Motor 2 is fixed on bank, and when needing repairing, motor 2 can be mentioned by straddle truck 1, and turbine 6 is left the water.Motor 2 is connected by main shaft 4 with turbine 6, and main shaft is spacing by the side arm in water channel and bearing 5.Wave pours in contraction water channel 8 by the big mouth 12 of broadening formation, and in vertical water channel 9, water surface extreme higher position is 11.Big mouth 12 is oval, and osculum is circular.It is presented herein below to break outside big mouth 12 and faces A directly, be possible to prevent ratchel to be washed into contraction water channel 8.The bottom B shrinking water channel 8 is downward-sloping, and the silt so entering contraction water channel 8 can slowly reflux, and prevents silt to be attached to shrink in water channel 8.After current enter vertical water channel 9, blade 7 adjusts propeller pitch angle automatically, starts to rotate.After startup, turbine carries out high speed rotating, has the highest energy conversion efficiency.When in water channel, the water surface declines, blade 7 reversely adjusts angle, direction of rotation and current and enters during water channel consistent.Water channel blow-by, is taken a breath with the external world by ventilation road 10.
