The realization process of a kind of breakwater and double gas chamber oscillating water column power generator is as follows:
1. gas chamber oscillating water column generating device structure designs:
Here research and optimization design mainly are carried out to whole device from this angle of the draft of oscillating water column device.
In general, the draft of curtain wall type breakwater is bigger, wave absorption performance is better, in double gas chamber oscillating water column power generator,
The increase of draft not only will increase the length of oscillating water column between front-back wall, also will increase in hang down plate horizontal direction stress surface
Product.To opposite draft d/h=0.1, the theoretical research process of 0.25,0.4 and 0.55 (d is draft, and h is the depth of water)
In, due to the difference of front and back gas chamber position, more wave energy enter preceding gas chamber, and average liquid level amplitude is apparently higher than in preceding gas chamber
Rear gas chamber.It is found during studying wave power conversion efficiency curve, the peak value of the curve is deep with the drinking water of works
The increase of degree and gradually decline, efficient frequency band also becomes narrow gradually.In 1 < ω of frequency band2(ω is incident wave frequency on h/g < 3.5
Rate, g are acceleration of gravity), when double gas chamber oscillating water column device drafts are d/h=0.25, wave power conversion efficiency is tieed up substantially
It holds 0.4 or more, there is very high engineering practice value.
2. wave is incident, Wave crest and wave trough alternating, wave energy acting in the gas chamber of front and back
When incidence wave is applied to oscillating water column power generator, the liquid level in device in preceding gas chamber and rear gas chamber is caused to occur
Fluctuation, the plate that hangs down under the action of wave force and elastic force, in surging occur have some cycles also with liquid fluctuating
It moves back and forth, in this course, the indoor gas motion of former and later two gas is total to by the plate that hangs down in liquid level and surging
Same-action.Gas in device is by vertical compression and the two-part compression of longitudinal compression, the gas push flowed into and out
The air turbine rotation that front and back gas chamber is connected, and then wave energy is converted electric energy storage by the generating set connected by turbine
It stores away.Since in process of wave propagation, hydrone kinetic energy is distributed mainly near Free Surface, the vertical of plate of hanging down in increase
The average pressure that length will make it be subject to reduces.Plate length of hanging down in the middle is d1/ h=0.1 (d1For the length for the plate that hangs down in surging)
When, total object is in 2 < ω2The wider frequency rate of h/g < 6, which takes, keeps good wave absorption performance, and the vertical of plate of hanging down in surging is prolonged
Stretch the reflection and absorbability that can be obviously improved works to long wave
3. generating set cooperates, electric power storage is powered alternately
In fact, there is two kinds of working conditions for front motor group and middle motor group during whole device use: electric before I.
Unit charging, middle motor group electric power storage；II. front motor group electric power storage, middle motor group charging.Here by taking situation I as an example to process 3. into
Row explanation: with the continuous compressed air to do work of water body in gas chamber, wave energy is gradually by the air turbine above airflow channel
It is converted into mechanical energy.Guide rod can be automatically adjusted, the state being connected with front motor group is now in, and disconnects and connecting with middle motor group
It connects.The mechanical energy of air turbine conversion is further converted to power storage in front motor by self-adjustable guide rod
In group, with the continuous acting of gas indoor gas, more and more electric energy are stored in front motor group, middle motor group at this time
It is constantly in the state that resident powers on island by conducting wire.As the charge capacity of front motor group reaches saturation, can adjust automatically
Section guide rod is disconnected with front motor group, and is connected with middle motor group, and front motor group continues to undertake to passing through conducting wire to island at this time
The task of resident's power supply on small island, and middle motor group then starts switch to wave energy the process that electric energy stores.In the middle
When motor group electric power storage reaches saturation, front motor group and middle motor group start to repeat the mistake of electric power storage and power supply on last stage again
Journey.And for rear motor group have can Multi Loading and Unloading Functions, during the work of oscillating water column power generator, it passes through always can be automatic
Adjust guide rod be connected with front and back air turbine, by because reach front motor group or in motor group electric power storage energy due to surplus electric energy storage
It stores away, shares the electric power storage pressure of front motor group and middle motor group.It, can be by the power generation when the power reservoir capacity of rear motor group saturation
Unit unloads, and by the stored grid-connected use of electric energy, huge numbers of families is facilitated to use, and the rear motor group more renewed.
The above content is only technical idea of the invention, and this does not limit the scope of protection of the present invention, all according to this
The technical idea proposed is invented, any changes made on the basis of the technical scheme each falls within the guarantor of claims of the present invention
Within the scope of shield.
