Description

The greenhouse

Technical field

The utility model relates to a kind of greenhouse, particularly a kind of greenhouse of selecting optical wavelength.

Background technology

Existing greenhouse, its sidewall and roof are mainly made by transparent materials such as glass, synthetic materials.Its operation principle is such: pass said these materials and enter into the sunshine in greenhouse after being reflected by the face of land in greenhouse or plant etc., wavelength can change, and sunray just can not pass said material after wavelength shift, thereby heat will accumulate in the greenhouse, when sunshine is very strong, it is very high that temperature in the greenhouse can rise, at this moment can be by lay the incident that dimmer board weakens sunray on the roof.This greenhouse is utilizing solar energy fully, improving the crop growth environment aspect plays a good role, but, because different plants has different demands indoor to light wavelength, the light wavelength variable effect is to the growth of plant, and greenhouse of the prior art does not have this function of selective light wavelength.

Invention constitutes

The purpose of this utility model is to overcome weak point of the prior art, not only can daylight be utilized and provide a kind of, also can select the wavelength of daylight simultaneously, more meets the greenhouse of plant growth characteristic.

The purpose of this utility model realizes by following approach.

The greenhouse comprises a substrate, sidewall and a transparent roof, and its structural feature is: this greenhouse also has an optical wavelength selective device, and it is arranged in the light incident passage in greenhouse.

Different plants have different requirements indoor to light wavelength, different light wavelengths directly have influence on the growth of plant, on the basis in common greenhouse, increased an optical wavelength selective device, thereby made the common greenhouse that only has heat insulation function originally have the function of selective light wavelength again.

The light incident passage in greenhouse, promptly sunray may enter the passage in greenhouse

The purpose of this utility model can also realize by following approach.

Optical wavelength selective device can be according to the demand of crop to light transmittance in practical operation, can select or be arranged at the roof be arranged at sidewall or be arranged at indoor, also can to select be to be arranged at above-mentioned roof, sidewall and indoor wherein any two kinds to go up, can also select to be arranged at simultaneously roof, sidewall and indoor.

Optical wavelength selective device can constitute by coloured transparent material or by transparent material and the colored liquid that is mounted in it forms, also can by coloured transparent material with adorn forming within it with the homochromy liquid of transparent material.

Described transparent material or be transparent synthetic material or for transparent glass or be transparent plastics.

When optical wavelength selective device is positioned at roof or sidewall, the light outgoing plane of optical wavelength selective device can be roof or sidewall, perhaps optical wavelength selective device itself is made of roof or sidewall exactly, at this moment, roof or sidewall have also played the effect of optical wavelength selective device except the partition effect of playing the greenhouse and the external world.

Described colored liquid can be a kind of aqueous solution.

The described aqueous solution is by water and be dissolved in that wherein pigment is formed or be made up of water and the pigment that is dissolved in wherein, and the selection of its color can be according to demand different dispose of different crops to optical wavelength.

Because the thickness of water layer directly has influence on the light transmittance in greenhouse, through experiment, think that light transmittance was comparatively desirable when the thickness x of the described aqueous solution was 0＜x≤25cm, when the thickness x of the aqueous solution is 18～20, light transmittance is ideal.

Described sidewall or be transparent, or be lighttight.

For the very big area of sunshine amounts such as desert, because the temperature in the greenhouse can rise very highly, therefore need set up a light incident adjusting device, with the incident of restriction sunray, to reach the purpose of control greenhouse temperature on the roof.

Described roof can be by many lengthwises, and being close to is that dull and stereotyped lath is formed, and lath can rotate by an axis on its longitudinally, by the rotation of lath, can regulate the solar radiation quantity that enters the greenhouse, thereby control the temperature in greenhouse.

In sum, the utility model has the following advantages compared to existing technology:

Owing to only need on the basis in common greenhouse, to set up optical wavelength selective device, and optical wavelength selective device itself is simple in structure, easy for installation, so the greenhouse structure that the technical program provides is simple, and is workable, and owing to increased optical wavelength selective device, make the greenhouse that only has heat insulation function have the function of selective light wavelength simultaneously, thereby make environment in the greenhouse more meet the growth characteristics of crop, the growth of more sharp and crop.
