Description
Technical field
The invention belongs to solar energy tracking technical field is and in particular to a kind of utilization sunlight heats the expansion in thermal-collecting tube
Fluid is tracked technology and the device of position of sun.
Background technology
Sun direct projection incident ray at earth certain point varies in operation at any time, in order to utilize too as much as possible
Positive direct solar radiation energy, helioplant requires to be equipped with the device being capable of tracking position of sun, most solar energy tracking devices
Based on electric driver, this kind of device tracking high precision, but consume energy during following the tracks of, and high cost.How by too
The energy of sunlight carrys out the device of tracking position of sun, that is, pass through the device of the solar tracking sun, do not consume energy, low cost, easy care,
There is very high application prospect and market value.
Retrieve existing published document, the document of the tracks of device driving with regard to sunlight heat does not also find.Retrieval
Patent documentation, has a technology to become the state-of-the-art technology more similar with the art of this patent.This technology is published " utilization
The patent of invention technology of the automatic method for tracking solar energy of temperature change ", its number of patent application is 201110286643.3, this skill
Art affects the fluid in expansion drum with the change of ambient temperature and expands with heat and contract with cold, the property driving hydraulic cylinder being expanded with heat and contract with cold using fluid
Stretch to follow the tracks of sun altitude, with the motion of double heat-absorbing chambers differential piston driving gear tooth bar, driven by the rotation of gear
Helioplant rotates to follow the tracks of the sun.This technology is clearly present problems with:
1st, this technology existence time hesitation in the morning, before start-up course and during solar receiver received
The solar energy arriving is few.This technology resets in night no light and is followed by receipts and faces up, when the sun rises in the Orient with one
The angle of incidence of individual very little is irradiated on solar receiver, and the solar energy received by solar receiver is little；Only
When direct sunlight line reaches some strength, under conditions of producing obvious temperature difference between two heat-absorbing chambers, this device is
Can east rotate, and sunlight is in the morning because of the impact of cloud, mist and sun altitude, beam radia have one slow on
, before direct sunlight line reaches some strength, there is certain period of time, this device can not have within this time period in the process of liter
Effect utilizes solar radiant energy, and therefore this device is in time lag effect.
2nd, this technology is non-normal incidence tracking technique, requires sunlight to keep with solar energy receiving plane during following the tracks of
One angle, and the weakening of the increase with solar azimuth and sunlight incident intensity, this angle becomes larger, and follows the tracks of by mistake
Difference also becomes larger.When sunlight impinges perpendicularly on two heat-absorbing chambers of this device, the temperature of two heat-absorbing chambers tends to one
Cause, now the equilbrium position of this device is face-up, local time the meridian hour only in a day, and sunlight vertically enters
Penetrate, this device is face-up, just meets this condition.In the morning or afternoon hours, this device will ensure to rotate towards the sun, must
Need ask in two heat-absorbing chambers and there is temperature difference, this temperature difference depends on the sensitive surface product moment of two heat-absorbing chambers, and will seek survival
Then necessarily require oblique being radiated on two heat-absorbing chambers of sunlight to be possible in sensitive surface product moment, therefore the non-local time just
The period of the day from 11 a.m. to 1 p.m divides, and this device receiving plane keeps an angle with sun incident illumination all the time.When solar azimuth increases, that is, the morning relatively
Time or afternoon more a little later, just need the temperature difference of the big intracavity it is desirable to two absorbs heat of angle of this device rotation earlier
Greatly, thus require the sensitive surface product moment of two heat-absorbing chambers to increase, this keeps one with regard to this device of further requirement and sun incident illumination
Individual larger angle, that is, the inherently required tracking error change of system is big.Further, in the morning, time or afternoon be relatively more earlier
A little later, solar radiation dies down it is ensured that a larger temperature difference is necessary for requiring bigger sensitive surface product moment, therefore should
Angle between device and sun incident illumination must increase further, and tracking error also mutually strains big.In a word, this technology is at noon
Time-division tracking error is little, and increase and intensity of solar radiation with solar azimuth weaken, and the tracking error of this technology becomes larger.
3rd, this device can automatically reset in cloud layer shading gap, the sun out after follow the tracks of again, but because do not have optically focused fill
Put, therefore there is a slow rotation tracking process, need a longer adjustment time.
4th, rack and pinion drive is linear displacement angle conversion device, it is desirable to tooth when that is, pinion rotation angle is identical
The distance of bar displacement keeps constant, that is, requires the volume expansion amount of thermal expansive fluid to keep constant, and in time morning and evening, the sun
The amount of radiation is less, and the temperature of thermal expansive fluid rises slowly, and therefore its tracking velocity is slow compared with noon, this device in a day
Velocity of rotation be difficult to keep constant, and be difficult to be consistent with sun rotational angular velocity, therefore its tracking error is larger.
5th, this technology is easily rocked under strong wind operating mode, easily causes the damage of device.The differential piston of double heat-absorbing chamber drives
Device requires to be filled with gaseous material, or half gaseous state semi liquid state material, if being completely filled with liquid object in two-chamber
Matter, due to the incompressible characteristic of liquid, the liquid heat-absorbing chamber of high temperature side is also impossible to extrude the heat-absorbing chamber of low temperature side and produces
Piston displacement, in addition when the temperature of the hot intracavity of double suction is all higher, liquid volume swell increment nowhere discharges, and can cause heat-absorbing chamber
Explosion.The device containing gaseous material for this inside, under strong wind operating mode, device easily rock by size with the wind, causes to follow the tracks of
Bigger error, and easily cause the damage of device.
