The specific embodiment
For further promoting the energy conversion efficiency of the clean and inexhaustible solar energy of nature, in the huge field of numerous energy consumptions, to apply, the utility model provides a kind of solar thermal collection system.Break through existing hot spot technology---the intrinsic thinking of heliostat heat build-up beacon system, develop a kind of optical principles such as optical focus, projection, reflection of utilizing to innovation, accomplish to make sunshine consistently towards a fixing receiver.Therefore no matter how the minute surface of optically focused rotates, and final primary optical axis does not still change, and is " heliostat " so temporarily define this collecting system herein.
As shown in Figure 1 to Figure 3, be structural representation, operating condition schematic diagram and the light path principle schematic diagram of a preferred embodiment of the utility model.By those accompanying drawings as seen: it is relative at the opposite side of condenser 1 focus projection surface to be installed, and the projecting mirror 2 that overlaps of focus, and condenser 1 and projecting mirror 2 are connected as a single entity by gyroscope type gimbals 4.The part that condenser 1 bottom shines in projected spot has 11, one speculums 5 of an open-work and is installed in this open-work 11 belows, links to each other with the hole frame with gyroscope type gimbals 4, and speculum 5 can rotate on the gyroscope type gimbals.Speculum, condenser and projecting mirror constitute mirror components, the key light axis bearing of trend of described speculum is provided with the receiver 3 of a fixed-site, and be provided with one in the key light axis and drive first motor that whole mirror components is rotated around primary optical axis, described first motor links to each other with electric control unit and controlled operation.
Technique scheme also can be optimized for: this solar energy collecting system of heliostat also is provided with an axial and perpendicular condenser angle adjustment assembly of mirror components rotating shaft, comprise the second motor draw bar 61 and the balancing weight 62 of cancelling out each other with respect to speculum center moment of torsion, the described second motor draw bar 61 joins with the condenser shady face.Above-mentioned first motor is with the optional stepper motor of second motor, servomotor or other similar precision are controlled motor herein.
Wherein this speculum is level crossing or the spherical zone mirror with annular concave surface; And the paraboloid of revolution that is shaped as the tool focusing performance of this condenser, or the concave mirror of dome shape; In addition, this receiver outer surface can also coat an adiabator layer or adopt vacuum thermal insulation technology to be incubated.
Reverberation through the speculum center is called primary optical axis, and first motor of key light axis place dress makes the mirror components of whole collecting system rotate around primary optical axis, follows the tracks of the sun east every day and rises the west and fall, and remains with sun synchronization and moves.In conjunction with the adjustment at the North and South direction elevation angle, remain sunlight and vertically shine on the condenser.Because whole condenser system is to be that initial point rotates around primary optical axis with S, the incident light on the speculum and the angle of primary optical axis are constant all the time, and incident beam (projecting beam) is through reflecting all the time along primary optical axis direction directive receiver.
The sun not single every day of east rises the west and falls, also move around between the tropic of Capricorn and the tropic of cancer every year, the angle that changes is about 47 °, is changed to 0.257534 ° every day, changes very little, for guaranteeing that focusing system can remain vertical with sunshine, obtain the best set thermal effect, one second motor is installed, make the whole condenser system can be around S axle left rotation and right rotation at the axle place of the vertical paper of S point, adjust the condenser inclination angle, make condenser and incident sunlight keep vertical.For guaranteeing that reverberation is constant along primary optical axis all the time, the elevation angle of adjusting speculum and horizontal direction makes incidence angle=angle of reflection.
When adjusting the condenser inclination angle with motor, adjust the elevation angle of reflective mirror simultaneously, can guarantee under the motionless situation of heated object (target or eyepiece) all the time can the most effective reception sunshine, accomplishes the requirement of " heliostat ".
If make reverberation become a luminous point at heat collector or heliostat place, speculum is made the spherical zone annular concave surface mirror of similar tire, and promptly secondary focusing gathers projection light become a bit.Above-mentioned heliostat system that should list mirror components form, the daily necessities that can be widely used in general masses sieve such as solar airconditioning, solar showering device, its condenser diameter need not to do very greatly, and need not to be assemblied in the roof and accept illumination constantly, promptly generated output that can be lower satisfies the requirement of life from loss-rate (less than 0.1%).
In addition, the solar energy thermal-power-generating that also has under the bright prospects more of solar energy collecting system of heliostat of the present utility model is used.Promptly this is stated collecting system and comprises an above mirror components and electric control unit separately, and described each electric control unit is parallel with one another, synchronous operation; And the key light axis of described each mirror components speculum converges at the relatively-stationary receiver in position (steam turbine or gas turbine etc.).Contrast now popular " heliostat " system, the utility model solar energy collecting system of heliostat has significant unit power cost advantage, from aspects such as space floor space, solar energy conversion using rate and generating consumables, all has some idea of.
So, the technical scheme of the utility model solar energy collecting system of heliostat, combination by condenser and projecting mirror, speculum, utilize optical principles such as focusing, projection, reflection to make the sun or astronomical radiation consistently towards a fixing receiver or eyepiece reflection, can effectively improve sun optically focused ratio and reach more than 100,000 times, provide convenience for people rationally utilize the solar energy of high temperature.Simultaneously, this system has simple in structure, combines with building and requires relatively low, with low cost advantage, helps solar energy resources applying and popularizing in fields such as civilian and scale heat-transmission generatings.
