Description

Sun automatic precision tracking device by orbit computing

Technical field the present invention relates to a kind of sun automatic precision tracking device by orbit computing, and it belongs to the solar energy source field.

Background technology is along with the development of World Economics, China's rapid economy development particularly, and the demand of the energy increases fast, and energy crisis has become current more and more distinct issues, and wherein, oil price sharp rises.The growth of the energy still increases based on non-renewable energy resources at present, and wherein, coal and oil remain main flow, have caused environmental pollution like this, and have increased the discharging of greenhouse gases.On earth, coal, oil, waterpower, wind-force equal energy source, its initial source is a solar energy.And solar energy utilization rate on earth itself is very low, only stays on the earth by very limited photosynthesis, and coal and oil are exactly with former cooperations in hundred million time energy that stay, but will be consumed totally by the current mankind very soon.People have ignored a problem, and that is exactly that solar energy is very huge, if the good good utilisation solar energy of people needs only and raises the efficiency a little, just the energy that necessary for human is wanted can be satisfied fully.In earth outer space, perpendicular to 1300 watts every square metre on the sun, about 1000 watts/meter of ground ², China has 9,600,000 square kilometres, 1 square kilometre=1000000m ²If the solar energy utilization of one thousandth area is arranged, suppose that conversion is for being original 50% perpendicular to the area behind the sun angle, ten thousand kilowatts of 9600 * 1000000 * 0.5=480000 are just arranged, about 2000 hours of short area of the time that shined upon in 1 year, then energy is 480000 * 2000=960000000, ten thousand kilowatt hours=82545.14187 ten thousand tons of standard oil=165090.2837 ten thousand ton standard coals, then the needed energy of almost enough China.At present the means of human use's solar energy very little, efficient is too low.And one of important means of raising the efficiency is the accurate tracking sun.Also not having at present can be simple and easy and accurate tracking equipment.

Summary of the invention the invention provides a kind of new, calculates the device of realizing the automatic accurate tracking of the sun by track.Pursuit movement can be decomposed into two motions, and two motions are circular motion, or the motion of uniform circular motion and the projection of another uniform circular motion on straight line.The earth has rotation, angle from relative motion, the rotation of the earth can be converted into the rotation of the sun around the earth, think that promptly ground is stone-dead, and the circumterrestrial north and south of sun contour evenly rotates, and the line of the sun and the earth is along with this rotation has formed a conical surface, the axle center of this conical surface and earth north and south axis parallel, and the angle of the conical surface is relevant with the date.When the sun reaches the north and south tropic, the angle minimum of the conical surface, and work as the sun in the centre of two tropic, in the time of promptly on the equator, the conical surface has become the plane.A straight line rotates with respect to another root and its crossing straight line, has promptly formed taper seat.So work as sun equipment over against the solar time, this equipment is evenly rotated along an axis parallel with earth North-South Axis, i.e. uniform circular motion, can realize to the sun from motion tracking, and the reciprocating motion of the angle of sun equipment and earth North-South Axis by the projection of another uniform circular motion on straight line realizes following the tracks of.

The present invention is by forming with the lower part: needs are followed the tracks of the equipment (convex lens of using as solar light focusing, parabolic mirror etc.) of the sun, to call sun equipment 1 in the following text; Permanent plant and the outer ring 2 that can allow sun equipment to rotate; Fixedly the outer ring also can allow the support 3 of outer ring rotation; Can drive the sun equipment beanpole 4 of sun equipment with respect to the outer ring motion; Can drive the outer ring beanpole 5 of outer ring motion; Make the drive plate 6 of sun equipment beanpole motion; Make the driving-belt (as chain) 7 of outer ring beanpole motion; Driving-belt fixed head 8; Drive plate fixed head 9; Mounting 10; Drive plate motor 11; Drive plate change-speed gearing 12; Driving-belt motor 13; Driving-belt change-speed gearing 14; The active node 15 of sun equipment 1 and outer ring 2; The active node 16 of outer ring 2 and support 3.
