Description
Technical field
It the utility model is related to a kind of control and device used be tracked to sea level during wave-energy power generation, especially
It is that floating drum is tracked device used to sea level in a kind of control float-type wave energy generating set.
Background technology
The total reserves of energy that ocean has are big, do not account for soil, the features such as non-pollution discharge, thus have increasing state
Family starts to pay attention to the research and development to marine energy resources, in addition, regenerable marine energy would is that China's Coastal Areas future
Important strategic novel energy.Ocean wave contains huge energy, can be by the energy conversion of wave by certain device
For mechanical, air pressure or hydraulic pressure energy, then driven and generated electricity by transmission mechanism, gas-turbine, the hydraulic turbine or hydraulic motor
Motivation generates electricity.The wave energy yield that there is economic value in the whole world is estimated as 1~1,000,000,000 kW.The theoretical reserves of Chinese wave energy are
70000000 kW or so.
The use of float-type wave energy generating set, it is to obtain more electric energy as far as possible, that is to say, that make it
Generating efficiency it is as high as possible.In floating drum wave energy generating set, the wave energy of floating drum capture is the energy source of whole device,
The efficiency of floating drum capture wave energy just determines the generating efficiency of floating drum wave energy generating set.And capture wave energy in floating drum
When, tidal range (difference in height of adjacent elevation of high water and elevation of low water is referred to as tidal range) becomes collection can the technical difficulty of device with float
Topic, and the problem of electricity generation system working time length.
At present, floating drum is fixed in Wave energy generating system device, will not be changed with the change of seawater reference plane (sea level)
Become.When there is flood tide and ebb tide process, capturing the floating drum fluctuating displacement of wave energy will be affected, it is impossible to normally capture ripple
It is unrestrained can and influence generating system apparatus operating efficiency.In normal tidal level, floating drum captures operating diagram such as Fig. 1 institutes of wave energy
Show, and set amplitude of oscillation angle above and below the support bar for connecting floating drum and be limited within 30 ° (it is assumed that floating drum moves amplitude of oscillation angle upwards
For+30 °, downward amplitude of oscillation angle is -30 °), now, floating drum fluctuating displacement is h0.Therefore, in normal tidal level, floating drum just can be
± 30 °, fluctuating displacement is h0In the range of swing, so as to capture wave energy, make system and device work generate electricity.
During flood tide, seawater reference plane (sea level) can rise because of tidal bulge, but due to capturing the floating drum of wave energy
It is fixed, it is impossible to rise with the rising of seawater reference plane (sea level).Therefore, in high tide level floating drum can only 0 °~
Moved in+30 ° of amplitude of oscillation angles, floating drum fluctuating displacement is h1, floating drum operational diagram is as Figure 1-3 during high tide level.Now, compare
Floating drum fluctuating displacement h when normal tidal level (as shown in Figure 2)0When have h1<h0.In other words, floating drum can not be completely in crest and ripple
Reciprocating between paddy, floating drum fluctuating displacement will be shortened, and its wave energy captured will be reduced with the increase of tidal range,
The utilization rate of wave energy will reduce, and the generating efficiency of wave energy generating set will be fewer.Even work as seawater reference plane (Hai Ping
Face) climb be more than or equal to floating drum cross-brace pole length L a half height when, when floating drum can be below or at trough, then
Floating drum, which is just fully submerged, no longer captures wave energy for Wave energy generating system work.Then, seawater reference plane (Hai Ping
Face) continue rise when, wave energy generating set is still in off position.
During ebb tide, seawater reference plane (sea level) can decline with ebb, but floating due to capture wave energy
Cylinder is fixed, it is impossible to is declined with the decline of seawater reference plane (sea level).Therefore, in low tide, floating drum can only be at 0 °
Moved in~-30 ° of amplitude of oscillation angles, floating drum fluctuating displacement is h2, floating drum operational diagram is as shown in Figure 3 during low tide.Now, compare
Floating drum fluctuating displacement h when normal tidal level0When have h2<h0.In other words, floating drum can not be made past completely between crest and trough
Multiple motion, the wave energy that floating drum captures will be reduced with the increase of tidal range, and the utilization rate of wave energy will reduce, wave
The generating efficiency of energy TRT will be fewer.Even when seawater reference plane (sea level) dropping distance is more than or equal to floating drum transverse direction
Support a pole length L half height, floating drum is higher than or during in crest, and floating drum is completely detached from the water surface and no longer captures wave energy confession
Wave energy generating system works.Then, when seawater reference plane (sea level) continues to decline, wave energy generating set is still in not work
Make state.
Therefore, in existing wave energy generating set, because floating drum is fixed, when tidal bulge and ebb, floating drum all can not normally be caught
Obtain wave energy so that TRT cannot fully work and be generated electricity, so that wave power utilization rate is low.

Applicant has carried out substantial amounts of experimental study to the utility model, and part is as follows：
1 Air-Water right angle prism design principle
The utility model comes from motion tracking sea level using the principle of Photoelectric Detection.Photoelectric Detection sea level system is basis
When light is propagated between the different material of two kinds of refractive indexes, will occur made of refraction principle, due to light by air or
Refractive index in seawater is different, and the result that optical receiving circuit receives is also just different.Prism is most in this optical system
Important optical element, light can occur to reflect twice by prism, so as to change the direction of propagation of emergent ray.Light passes through
Emergent ray can be received along straightline propagation, receiver during prism full of air, index path is as shown in Figure 5；And light passes through
During prism full of seawater, by reflecting twice, the direction of propagation of emergent ray can shift, so as to which receiver can not connect
Emergent ray is received, index path is as shown in Figure 6.
Accordingly, it is possible to using the measurement of two groups of detectors, during further according to light by air and seawater, optical receiving circuit connects
The signal received is compared, processing, so as to judge the position on seawater reference plane (sea level).This signal passes through 51 single-chip microcomputers again
Processing, output signal control floating drum moving direction, realizes that floating drum automatically controls the function on tracking sea level.
The relation of 1.1 medium prism incident opticals and emergent ray
As shown in fig. 6, Ray Of Light using incidence angle asInjected from prism AB faces, refraction angle r, at this moment light beam is in mirror
The deviation angle on the AB of face is
Now, light continue propagate using incidence angle asPrism AC planes are injected, refraction angle is r '.At this moment light beam is in mirror
The deviation angle on the AC of face isThe deviation angle is made to be represented by " θ ".From geometrical relationship, after deviation twice, light beam
Always the deviation angle is：
From formula (1-1) as can be seen that light by the deviation angle caused by prism not only with angle of incidence of lightAbout also and
The drift angle A of prism is relevant.Under conditions of taking refractive index n=1.5, by MATLB software analysis formula (1-1), one can be obtained
The individual deviation angle and incidence angle, a graphics of drift angle variation relation are illustrated in fig. 7 shown below：Wherein Z axis represents the deviation angle, X-axis generation
Table incidence angle, Y-axis represent drift angle.
In this figure, can be clearly visible that, in incidence angle and drift angle infinite approach maximum, the deviation angle also obtains maximum
Value.
1.2 medium prism incident opticals and the relation of incidence angle change
If light is injected after prism reflects twice from AB faces, light comes out from AC planes, then light can be deposited
In a minimum incidence angle.When incidence angle is less than light minimum incidence angle, light can produce total reflection in second plane of refraction,
Here it is the prism total reflection characteristic that we often say.We will be analyzed under prism total reflection condition below, show that light exists
The minimum incidence angle that AC faces are shot out.So as to draw in given prism, i.e. drift angle and the certain condition of prism refractive index
Under, the changing rule of the deviation angle and incidence angle is drawn according to formula (1-1).
Occur to reflect twice when light passes through prism, full transmitting, index path such as Fig. 8 institutes are produced when reflecting for second
Show, if the drift angle of prism is A, refractive index n, light is with incidence angleIncide plane prism AB planes, refraction angle r.
Refracted light is again with incidence anglePrism AC faces are mapped to, and it is r '=90 that total reflection occurs just.
Incidence angle now is referred to as maximum incident angle during prism full transmitting, i.e.,
Thus, it is possible to obtain, when angle of incidence of light is more than total reflection maximum incident angle, light can be penetrated into prism AC planes
Go out, so as to produce shown in the deviation angle such as formula (1-1), now, light has minimum incidence angle
That is the span of incidence angle isWhen, emergent ray is necessarily from AC faces
Project.In other words, when the incidence angle of incident ray is less than maximum incident angle, i.e.,
When, light just produces total reflection on AC faces.If n=1.5. can draw change of the maximum incident angle with drift angle A using MATLAB
Change graph of a relation such as 9 to show：
As can be seen from Figure 9, when drift angle is less than 1.57 (90 °), maximum incident angle is similar to exponential increase with the increase of drift angle,
When drift angle reaches 1.57 (90 °), maximum incident angle is 90 °.When having exceeded 1.57 (90 °), maximum incident angle is kept for 90 ° not
Become.That is when the drift angle of prism is equal to 1.57 (90 °), incidence angle is with any angle incidence prism, in AC faces all
Total reflection can be produced to project without light.
1.3 emergent rays and the relation of drift angle change
Understand that the prism deviation angle is relevant with the drift angle of prism, and the deviation angle can be with the change of drift angle according to formula (1-1)
And change.From incident ray and the relation of incidence angle, when incidence angle is less than imaxWhen, light can produce in prism AC faces
Total reflection, therefore light projects on AC faces, at this moment there is minimum incidence angle in incidence angle, and incidence angle is less than or equal to 90 °.Be into
The span of firing angle isNow have：
Therefore, it can be said that to realize Fig. 1-4 index path, the drift angle A of that prism must have a maximum：
N=1.5 is taken, then Amax=83.6206 °, if A has exceeded maximum drift angle Amax, then Figure 10 light path may occur
Figure.Light can be totally reflected in Figure 10, so that in prism AC faces without emergent ray.Therefore, as long as the drift angle of prism is big
InWhen, then light can produce total reflection in prism AC faces, so as to have light from AC
Project in face.
It is right-angle prism to have kind of a special prism, according to Figure 10, takes A=90 ° of the drift angle of prism, then formula (1-2) can
It is reduced to：
The change curve that maximum incident angle and refractive index are obtained using MATLB softwares is illustrated in fig. 11 shown below：
Forgoing describe, if the incidence angle of incident ray is less than maximum incident angle, light just produces complete on AC faces
Reflection, in other words when incident ray is more than maximum incident angle, then light cannot produce total reflection again on AC faces.By
Figure 11 understands the maximum incident angle being totally reflectedIncrease with the increase of refractive index.As refractive index n >=1.41, most
Big incidence angle is 90 °, no matter so when incident ray is with great incident angles, total energy occurs on right angle prism AC faces
Full transmitting, now its index path is as shown in figure 12：
Analyzed more than, occurs compared to several light drawn before on AC faces needed for total reflection to incidence angle, push up
Under the restrictive condition at angle, right angle prism is easier to obtain the total reflection of light.Because no matter how incidence angle injects prism,
Light can all produce total reflection, i.e. light will not project from prism AC faces.In this optical system, when light ray parallel is horizontal
When the direction incidence in face is full of the prism of air, light meeting straight-line pass prism, so as to conplane reception over there
Device can receive illumination, same device, and when light is by prism full of seawater, full transmitting occurs in AC faces for light, thus
Receiver can not receive any light.So as to reach the result of design.Therefore, in system design, we use right angle three
Prism injects the right-angle side of right angle prism as optical element, light ray parallel in horizontal plane direction.
2 system detectio circuit diagrams

Seawater is not present between survey device LED1-D1, when LED1 sends illumination, light can directly be propagated along air and connect by phototriode D1
Receive.After phototriode receives light, its base stage, which can produce a big electric current, makes triode ON, then by operation amplifier
The processing of signal processor, output signal can make diode (LED) 3 not work, and P1.0 ports are low level.Low level detector
Seawater between LED2-D2 be present, when LED2 sends illumination, light be able to can occur entirely in by the right angle prism full of seawater
Reflection, so as to be received by phototriode D2, now, its base stage, which can produce electric current very little, ends triode, Ran Hou
By the processing of operation amplifier signal processor, output signal can light diode (LED) 4, and P1.1 ports are high level.
At the incoming tide, seawater benchmark sea level would be on two groups of detectors, now detector LED1-D1 and LED2-
Seawater between D2 all be present, then output signal makes LED3 and LED4 light, and P1.0 ports and P1.1 ports are high level.This
When, in order to reduce the influence of flood tide, floating drum will be with sea level rise, and photoelectric testing sensor and floating drum are intended to move up, until
Just stop moving up when LED3 does not work, now sea level is between two detectors.During ebb tide, sea level would be at two groups
Under detector, seawater is now all not present between detector LED1-D1 and LED2-D2, then output signal makes LED3 and LED4
Do not work, P1.0 ports and P1.1 ports are low level.Now, in order to reduce the influence of ebb tide, floating drum will be with sea level
Drop, photoelectric testing sensor and floating drum are intended to move down, just stop moving down when LED4 is lighted, and now sea level is in two
Between test point.So as to reach the purpose of detection sea level liquid level.Compared with prior art, the utility model is by using two groups
The measurement of optical detection system, during further according to light by air and seawater, the signal that optical receiving circuit receives is compared, place
Reason, so as to judge the position on sea level, this signal is handled by single-chip microcomputer again, output signal control floating drum moving direction, is realized
Floating drum automatically controls the function on tracking sea level.That is, the utility model can carry out detect and track to sea level, make floating drum in tide
It can rise when rising with the rising on sea level, decline with the decline on sea level during ebb, so as to reduce the influence of tidal range, catch
More wave energies are received, TRT is worked in macrotidal range marine site, extend wave energy generating set work
Time, so as to improve wave energy generating set to the utilization rate of wave energy and its stability to generate electricity.Therefore, the utility model
Floating drum can be made to float, when tidal bulge and ebb, floating drum can normally capture wave energy, so that wave power utilization rate is high so that hair
