Description
Technical field
The invention belongs to solar energy tracking technical field, be specifically related to a kind of technology and device that utilizes expansion fluid in sunlight heating thermal-collecting tube to carry out tracking position of sun.
Background technology
The sun direct projection incident ray of a bit locating at the earth is changing in operation at any time, in order to utilize as much as possible direct solar radiation energy, helioplant require to be equipped with device that can tracking position of sun, most solar energy tracking devices be take electric driver as main, this class device tracking precision is high, but in tracing process, consume energy, and cost is high.How can carry out by the energy of sunlight the device of tracking position of sun,, by the device of the solar tracking sun, not consume energy, cost is low, and easy care has very high application prospect and market value.
Retrieve existing published document, the document of the tracking means driving about sunlight heat does not also find.Patent searching document, has a technology to become and the comparatively similar state-of-the-art technology of the art of this patent.This technology is the patent of invention technology of published " utilizing the automatic method for tracking solar energy of variations in temperature ", its number of patent application is 201110286643.3, this technology is expanded with heat and contract with cold with the fluid in the variable effect expansion drum of ambient temperature, utilize property driving hydraulic cylinder extension that fluid expands with heat and contract with cold to follow the tracks of sun altitude, with the motion of the differential piston actuated rack-and-pinion of two heat-absorbing chambers, the rotation by gear drives helioplant to rotate to follow the tracks of the sun.This technology obviously exists following problem:
1, this technology life period hesitation in the morning, before start-up course and in process, the received solar energy of solar receiver is few.This technology night unglazed according to time reset after receiving plane upward, when the sun rises in the Orient, with a very little incidence angle, be irradiated on solar receiver, the received solar energy of solar receiver seldom; Only have the direct sunlight line of working as to reach some strength, between two heat-absorbing chambers, producing under the condition of obvious temperature difference, this device could rotate east, and sunlight is in the morning because of the impact of cloud, mist and sun altitude, direct solar radiation has a rising process, at direct sunlight line, reaches before some strength, has certain hour section, within this time period, this device can not effectively utilize solar radiant energy, so this device is in time lag effect.
2, this technology is non-normal incidence tracking technique, in tracing process, require sunlight and solar energy receiving plane to keep an angle, and along with the increase of solar azimuth and weakening of sunlight incident intensity, this angle becomes greatly gradually, it is large that tracking error also becomes gradually.When sunlight impinges perpendicularly on two heat-absorbing chambers of this device, the temperature of two heat-absorbing chambers reaches unanimity, and now the equilbrium position of this device is for facing up, local time the meridian hour in one day only, sunlight vertical incidence, this device faces up, and just meets this condition.In the morning or the period in the afternoon, this device will guarantee to rotate towards the sun, necessarily require to have temperature difference in two heat-absorbing chambers, this temperature difference depends on the sensitive surface product moment of two heat-absorbing chambers, require to exist sensitive surface product moment to necessarily require that sunlight is oblique to be radiated on two heat-absorbing chambers just likely, therefore at non-local time the meridian hour, this device receiving plane keeps an angle with sun incident light all the time.When solar azimuth increases, in the morning, time or afternoon be more earlier, the angle that needs this device to rotate is large, require the temperature difference in two heat-absorbing chamber just large, thereby require the sensitive surface product moment of two heat-absorbing chambers to increase, this just further requires this device and sun incident light to keep a larger angle, and the inherent tracking error requiring of system becomes large.Further, in the morning, time or afternoon, solar radiation died down, and guarantee that a larger temperature difference just necessarily requires larger sensitive surface product moment more a little later more earlier, therefore the angle between this device and sun incident light must further increase, and also phase strain is large for tracking error.In a word, this technology at noon time-division tracking error is little, with increase and the intensity of solar radiation of solar azimuth, weakens, and it is large that the tracking error of this technology becomes gradually.
3, this device can automatically reset in cloud layer shading gap, follows the tracks of after out again, but because there is no beam condensing unit, therefore exist one slowly to rotate tracing process at the sun, needs a longer adjustment time.
4, rack and pinion drive is linear displacement angle conversion device, be that gear rotational angle is when identical, require the distance of rack displacement to remain unchanged, namely require the volume expansion amount of thermal expansion fluid to remain unchanged, and in time morning and evening, the amount of solar radiation is less, the temperature of thermal expansion fluid rises slow, so its tracking velocity is slow compared with noon, and in one day, the velocity of rotation of this device is difficult to remain unchanged, and very difficult and sun rotational angular velocity is consistent, so its tracking error is larger.
5, this technology is easily rocked under strong wind operating mode, easily causes the damage of device.The differential piston driver of two heat-absorbing chambers requires to fill in inside gaseous material, or half gaseous state semi liquid state material, if be all full of liquid in two-chamber, incompressible characteristic due to liquid, the liquid heat-absorbing chamber of high temperature side also can not push the heat-absorbing chamber of low temperature side and produce piston displacement, when the temperature in two heat-absorbing chambers is all high in addition, liquid volume swell increment discharges nowhere, can cause the explosion of heat-absorbing chamber.The device that gaseous material is contained in this inside, rocks in the easy size with the wind of strong wind operating mode lower device, causes tracking error bigger than normal, and easily causes the damage of device.
