Abstract
The utility model relates to a double-focusing all-optical acquisition device, which comprises a ring-shaped parabolic mirror, a spherical concave mirror and an all-optical light guide pipe. Sunlight is reflected and focused by the ring-shaped parabolic mirror, is reflected again by the concave mirror and enters the all-optical light guide pipe. The all-optical light guide pipe comprises a glass pipe, a reflector film arranged on the outer wall of the glass pipe and a plastic sleeve which is in close fit with the outer periphery of the reflector film. The double-focusing all-optical acquisition device of the utility model has low cost, is flexible to install, can be conveniently independently used or combined into a movable mode, a wall hanging mode, an eave installing mode or an overhead installing mode according to different requirements of the using places on lighting, sunshine, illumination and the like, and is particularly suitable for high-power high energy level optical density sunlight lighting systems in the different application fields of engineering buildings for civil, public, underground, well underground and the like and industry, agriculture, planting, cultivation and the like.
Description
Technical field
The utility model relates to the technical field that solar light focusing is gathered, and specifically is the full light collection device of a kind of double focusing.
Background technology
Green energy resource has become the energy industry focus, and particularly the continuous development and the energy demand trend of urban modernization building make the sunshine, daylighting, the illumination that utilize sunshine to improve building to become a reality and possibility.It is a lot of year that the sunlight collecting technology has existed, but always because cost an arm and a leg, and inherent characteristic is bad and can't popularize.This technical costs and technical complexity mainly concentrate on the tracks sunlight device and sunshine imports employed light-conductive media---optical fiber.
Solar follow-up device mainly contains dual mode: a class is high stability, high accuracy mode; An other class is stability, the poor slightly mode of precision.The former calculates sun whole year operation track according to the earth around sun moving law, contain the position of sun checkout gear, " photoelectric sensor " installed by bonding apparatus central authorities, and the mixed mode of track of sun calculations incorporated photoelectric tracking just is as " sunflower " sunlight lead-in daylighting device of Japan.Its shortcoming is the tracking means complexity, and the initial position required precision of installation is than higher, and installation inconvenience and lighting equipment price are higher.In addition, this device also is subject to the cloud layer influence.The latter also can be divided into two classes according to the mode of information processing: the first compares photosignal by analog form, drives direct current generator.Though this type of mode precision is lower, cheap.An other class is to adopt photosignal is converted to data signal, improves stability and precision by the microprocessor processes signal, the technology of declaring as patent 200710022259.6.But the document still adopts direct current generator, rather than stepper motor, so the improvement of precision is limited.
Expensive another factor is to have adopted expensive silica fibre, as " sunflower " of Japan, " the blue sunlight of the handkerchief system " of Sweden.Though domestic some other patent has adopted plastic optical fiber as 200710022259.6, but because light path design is unreasonable, adopting big lens to substitute a plurality of lenslets reduces required precision and makes complexity, but because of big lens cause strong chromatic dispersion easily, cause emergent light colourful, can't reduce sunlight.To be optically coupled into optical fiber efficient low for this patent middle-jiao yang, function of the spleen and stomach simultaneously.
In sum, at present lighting equipment to cost an arm and a leg and can't popularize be because adopt optical fiber as the leaded light transmission medium.For the solar energy that makes collection is coupled into optical fiber, further aggravate the complexity of lighting equipment, as the tracking of the sun, sunlight is coupled into the focusing of optical fiber.
Summary of the invention
The utility model relates to the full light collection device of a kind of double focusing, with the problem of the expensive and technical sophistication that overcomes silica fibre and plastic optical fiber.
For solving the problems of the technologies described above, the utility model provides a kind of double focusing full light collection device, it comprises: the full light collection device of double focusing, the full light collection device of this double focusing comprises: annular paraboloidal mirror, with annular paraboloidal mirror coaxial line, with the spherical concave mirror that focus is provided with in opposite directions, be arranged in the center through hole of annular paraboloidal mirror and the full light photoconductive tube of cylindricality light beam that is suitable for receiving the concave mirror reflection annular paraboloidal mirror coaxial line; Full light photoconductive tube comprises: glass tube, be located at the reflector surface film of glass tube outer wall and tightly fit in the plastic bushing of reflector surface film periphery.
For preventing that glass tube from absorbing the heat energy of sunshine, simultaneously for guaranteeing to realize the purpose of full photoconduction light, described glass tube is the glass tube of metal ion not.
What is called is light entirely, promptly comprises the light of the various wavelength in the sunray in the light.
Good effect of the present utility model: the full light collection device of (1) double focusing of the present utility model, cost is low, and is flexible for installation; Can be according to the different demands such as daylighting, sunshine and illumination of field of employment, can conveniently be alone or combined into movable type, wall-hanging, eaves installing type, overhead installing type, be particularly useful for the sunlight collecting system of high-power, the high level optical density in different purposes fields such as engineering constructions such as civilian, public, underground, down-hole and industry, agricultural, plantation, breed.(2) reflective surface of the spherical concave mirror of the utility model employing is spherical concave surface, with respect to adopting parabolic mirror, has short focal length, the described cylindricality light beam of Sheng Chenging has less sectional area simultaneously, be beneficial to the volume that reduces the full light collection device of whole double focusing, also be beneficial to the caliber that reduces full light photoconductive tube, to save manufacturing cost and installing space.In addition, the less light beam of sectional area is beneficial to and improves the conduction efficiency of light beam in the photoconduction pipeline, can reduce the quantity of the light of propagating in the broken line mode in the photoconduction pipeline.(3) the annular paraboloidal mirror of the utility model employing ringwise, the foreign material that fall within on this annular paraboloidal mirror are discharged from its center through hole, can less labor cleaning, the workload of maintenance, also can less described foreign material to the influence of paraboloidal mirror reflecting effect.
