Description
Technical field
The utility model relates to a kind of greenhouse by solar heat of agricultural products, relates in particular to a kind of agricultural greenhouse by solar heat that has back wall and heat-insulation layer.
Background technology
In the current protection ground agricultural production, the maximum protection facility of area is greenhouse by solar heat and big arch shed, and greenhouse by solar heat is that protective condition is best; Can the anniversary carry out agricultural production in a lot of areas of northern China; Big arch shed takes second place, but is difficult to carry out produce in the anniversary, and especially the severe winter is difficult to produce.The two is compared, and greenhouse by solar heat has following characteristics: 1. the thermal isolation and heat storage performance is good, but construction and use cost are higher; 2. land utilization rate is lower, has only 45-55%; 3. can only be from daylighting in the south, its excess-three face is light tight.Big arch shed is then opposite, and construction and use cost are lower, poor-performing, but daylighting comprehensively, and land utilization rate is up to 85-90%.
The thermal isolation and heat storage in greenhouse mainly is to lean on cob wall, and in the cob wall to the accumulation of heat contribution maximum be moisture wherein, the increase of the height of cob wall, thickness, humidity helps insulation and accumulation of heat.As cob wall, humidity can not be too big, humidity too big one be unfavorable for firm, the 2nd, the moisture that scatters and disappears easily, and the increase of its height and thickness needs a large amount of Tu Yuan to support, and the availability of reduction land area also can influence the daylighting effect of north side, greenhouse.
In general; Greenhouse by solar heat has the three face wall bodies arc daylighting face to the south with one side; Daylighting face is covering the insulation thing with insulation at night; Also have an inclined-plane on the back wall in present most greenhouses, make the back domatic, the back is domatic to be generally used for placing night insulation thing or people walking usefulness when on the greenhouse, working.Because domatic general of back has the scattered light entering; If domatic cover film at this moment; The illumination energy that gets into the greenhouse is less than through the film dispersed heat, and the temperature the during cloudy day in the greenhouse is difficult to improve has explained this point, and in fact because after wall than higher; All the time do not get direct light the back domatic winter in greenhouse, and can only play insulation effect can't daylighting.And, because the domatic wide more then weight in back is big more, the more difficult upright supports of use, so, the narrow adverse grade of the many employings in existing greenhouse, like this after wall just will inevitably be very high, just produced the very wide back wall in the north and south band that shades naturally, formed unavailable land area.
For the lighting effect that obtains, the very thin transparent membrane of the general employing of daylighting face, daylighting face can not play the effect of thermal isolation and heat storage in this case, and a lot of heats simultaneously will constantly scatter and disappear.So with regard to same seat greenhouse by solar heat, daylighting area and thermal isolation and heat storage are a pair of contradiction, the increasing of daylighting area means the reduction of thermal isolation and heat storage ability.Greenhouse by solar heat is provided with the back wall, and the thermal isolation and heat storage ability is strong, thus can the anniversary produce, though big arch shed daylighting is good, can not thermal isolation and heat storage, just can not produce in the anniversary.
It is long back domatic to have only the minority greenhouse to have at present, but opaque, so the north side is dark in the greenhouse, can not produce preferably, and the soil output of unit are receives very big influence.
The utility model content
The technical problem that the utility model will solve is the contradiction between greenhouse lighting and the thermal isolation and heat storage, makes back wall height can reduce, realize roomy daylighting and the insulation that the back is domatic, when improving greenhouse lighting efficient, keeps the thermal isolation and heat storage ability in greenhouse.
The utility model provides a kind of greenhouse by solar heat; Close by the back circummure of the both sides gable of thing face and north side and to form; The line of said both sides gable peak forms greenhouse spine, and the gable height northwards reduces from spine southwards gradually, and is domatic before the front side, greenhouse is formed; It is domatic that the greenhouse rear side forms the back; Before domatic and back domatic be provided with many laterally or longitudinally load-bearing line or spandrel girders, lay transparent insulating layer on preceding domatic load-bearing line or the spandrel girder, domatic load-bearing line or the spandrel girder in back is provided with transparent foamed material layer.Now the transparent insulating layer that adopts of greenhouse is generally plastic film, and the present technique scheme changes very short back domatic in original greenhouse into can be in the morning and the inclined-plane that gather direct light at dusk, increased daylighting area, and transparent foamed material layer is set in the back on domatic.Transparent foamed material layer has improved the ability of thermal isolation and heat storage than simple plastic film, can reduce the speed that the greenhouse heat runs off, and makes roomy back domatic can the use in practice.Domatic the going up in back uses transparent foamed material layer can use like materials such as foaming EPE, hollow PVC plates, also can outside transparent foamed material layer, add a cover transparent thin film layer again.Strengthened the daylighting property in greenhouse like this, and by the thermal insulation of material, made illumination energy from the domatic entering in back greater than dispersed heat; Simultaneously because transparent insulate material is extremely light; Make and no longer receive the domatic lengthening that is easy in back the restriction of weight, thereby increase substantially the greenhouse land utilization rate.
Preferably, said back wall and both sides body of wall are hollow wall, are placed with enclosing liquid in the said hollow wall.Said enclosing liquid is bottle or packed Heisui River, perhaps for deceiving the water of bottle or black bag encapsulation.Because the heat capacity ratio of flowing fluid ratio such as water is high, store heat is effective, after wall place the ability that has obviously improved its thermal isolation and heat storage behind the enclosing liquid, make greenhouse temperature in evening fall slowly, day and night temperature is little in the greenhouse like this, is more conducive to the growth of crops.For better absorptive thermal radiation, the color of water and/or its packing material is a black.Heisui River can also use the water-soluble humic acid potassium of separating to process, in case become pollution source in the future.In order better to bring into play the heat that stores in the wall of back, wall outside, said back is provided with fixedly heat-insulation layer, can adopt the thick black foaming EPE compound reflecting film of 3mm, prevents that effectively heat from distributing outside the greenhouse.
