As the oil of traditional energy, natural gas, coal, when the water source equal energy source is used up, and the leading energy of human being's production life is still these energy, and the mankind can't survive.In the development in future, the mankind must seek these energy that are about to exhaust of new energy substitution.Well-known solar energy is the natural resources the most typical, that energy is the strongest, is without expense, inexhaustible, the nexhaustible energy, but only has seldom a part inject indoor, most of along with having passed in vain by glass, skylight.When the current whole world all faces energy crisis, how more reasonable, utilize better solar energy, be the problem that each state is all seeking.In modern building, the especially urban skyscraper, rooms that much throughout the year can not see sunlight are often arranged, even the outside is sunny, and indoorly also utilizing artificial light sources to throw light on, to satisfy the deficiency of daylighting.Sunlight is then can not see in basement, subway, underpass, market place builet below the ground, tunnel etc. especially.Science proves, the sunlight of nature is highly profitable to health and environment, and under the environment of available light illumination, people are healthy, energetic, notice strengthens, and operating efficiency also can greatly improve.At present, collection sunlight of the prior art is introduced indoor device and is generally all comprised several parts such as sunlight beam condensing unit, light transmitting device, sunshine tracking control device, and two ranges of exposures are limited or not enough and market is very little; Huge structure is complicated, function singleness, inconvenience is installed and is unfavorable for that marketing uses, and some product is not then because structural defective is suitable for practical application, and transmission range is short, does not have use value.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of beam condensing unit sunshine light-guiding mechanism is provided.This beam condensing unit is simple in structure with the sunshine light-guiding mechanism, volume is little, the utilization rate of raising luminous energy, has broad application prospects.
For achieving the above object, the technical solution adopted in the utility model is: beam condensing unit sunshine light-guiding mechanism, it is characterized in that: comprise the shading support and be arranged on described shading support interior convex lens and paraboloidal mirror, described shading support is the cylinder of a hollow, one end of described shading support is provided with cover plate, and the outward flange of described cover plate is provided be used to the fastener that is fastened on the shading support, the other end of described shading support is opening, described convex lens are installed in the convex surface of the openend of shading support and convex lens towards the outside of shading support, the inwall of described shading support is provided with for the bracing frame that supports paraboloidal mirror, described convex lens and paraboloidal mirror space, the optical axis of described convex lens and the optical axis of paraboloidal mirror are located on the same line, described paraboloidal mirror is connected with optical fiber away from the one side of convex lens, described optical fiber passes cover plate, and described optical fiber and cover plate closely cooperate, the inwall of described shading support is provided with a plurality of grooves for the clamping bracing frame, one end of described groove extends on the shading stent length direction end away from convex lens, described convex lens are made of plastics, and the outer surface of described convex lens scribbles anti-reflection film, the outer surface of described paraboloidal mirror is coated with reflective film, and described optical fiber is hollow network structure.
Above-mentioned beam condensing unit sunshine light-guiding mechanism is characterized in that: described optical fiber is connected with paraboloidal mirror by sealing ring.
Above-mentioned beam condensing unit sunshine light-guiding mechanism is characterized in that: the end near convex lens on the described groove is provided be used to preventing the block of paraboloidal mirror near convex lens.
The utility model compared with prior art has the following advantages:
1, of the present utility model simple in structure, rationally novel in design, be easy to install.
When 2, the utility model uses, after focusing on, the sunshine planoconvex lens becomes fritter face zone, more through the laggard light that enters optical fiber of paraboloidal mirror secondary focusing again, loss still less, the light that can not cause entering in the optical fiber because of the little error of tracking system like this reduces sharply.
3, the utility model is mobile in groove by bracing frame, has made things convenient for the installation of bracing frame and paraboloidal mirror, also convenient adjustment to spacing between paraboloidal mirror and the convex lens.
4, realization cost of the present utility model is low, and result of use is good, is convenient to promote the use of.
In sum, the utility model is simple in structure, and rationally novel in design, functional reliability is high, long service life, and the utilization rate of raising luminous energy has broad application prospects.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
