Description
Technical field
The present invention relates to a kind of greenhouse by solar heat, specifically, relate to a kind of high land utilization rate greenhouse by solar heat, belong to vegetable growing technical field.
Background technology
Common energy-saving heliogreenhouse is the agriculture and garden facility forming on the basis of solar energy scientifically utilizing, and has that utility rate of luminous energy is high, a quick heating, feature extremely efficient in preserving heat.Even the in the situation that of manually not heating in the severe winter, also can produce the multiple thermophilic vegetables such as cucumber, tomato, eggplant, peppery (sweet) green pepper.
At present, the body of wall of the good common energy-saving heliogreenhouse of heat insulating ability is rammed earth construction, and body of wall is built with excavator and bulldozer, and thickness of wall body is generally 4-5.5m, and body of wall takies a large amount of land areas, causes the land utilization rate of greenhouse by solar heat lower.Meanwhile, the greenhouse by solar heat that body of wall is rammed earth construction need to fetch earth in a large number and pile up body of wall in greenhouse, forms under cultivation bed and digs formula greenhouse, greenhouse wall body very large by soil amount after fetching earth.
Adopt the common energy-saving heliogreenhouse heat-retaining of rammed earth construction body of wall strong, can make the temperature in fine day of daytime of greenhouse by solar heat can not rise too fastly, too high.At night in the winter time, the temperature in greenhouse by solar heat falls soon, and when warm indoor temperature is during lower than the temperature of cob wall body 50cm internal layer, the heat of body of wall internal layer just can discharge in the air in greenhouse, makes the temperature in greenhouse unlikely too low.
Yet in realizing process of the present invention, inventor finds at least to exist in prior art following problem: the greenhouse by solar heat of traditional rammed earth construction body of wall, land utilization rate is low.For example, the greenhouse by solar heat of long 80m, an interior span 12m, wall and thing two wide 5m in gables bottom thereafter, floor space (spacing distance in two greenhouses before and after not comprising) is 1530m
2, effectively soil utilizes area for 960m
2, effective use of land rate is only 62.7%; The solar greenhouse wall body of rammed earth construction body of wall is thick, large by soil amount, need in greenhouse, fetch earth in a large number and pile up body of wall, must cause forming under cultivation bed and dig formula greenhouse by solar heat.Under this cultivation bed, dig formula greenhouse by solar heat, be unsuitable for the more shallow regional Construction of subterranean water level.
Summary of the invention
The technical problem to be solved in the present invention is for above deficiency, a kind of high land utilization rate greenhouse by solar heat is provided, overcome in prior art land utilization rate lower and be unsuitable in the subterranean water level defect that relatively shallowly district builds, adopt the greenhouse by solar heat after the present invention, there is land utilization rate high, build and be not subject to Effect of Underground Water Level and heat accumulation, heat-insulating property and have advantages of that the greenhouse by solar heat of rammed earth construction body of wall is suitable.
For solving above technical problem, the present invention by the following technical solutions: a kind of high land utilization rate greenhouse by solar heat, comprise rear wall, gable, column and scarp slope, it is characterized in that: described greenhouse by solar heat also comprises heat accumulation ditch, top operational platform and waterproof platform;
Described rear wall comprises support frame, polyphenyl foam plate and Reflecting curtain, and polyphenyl foam plate is fixed on support frame, and Reflecting curtain is fixed on the inner side of polyphenyl foam plate;
Described waterproof platform is arranged on rear wall outside, equal in length outside the length of waterproof platform and rear wall;
Described column comprises rear column and front column, and Reflecting curtain, polyphenyl foam plate are arranged between rear column and front column, and the height of rear column and front column is identical with scarp slope peak;
Described heat accumulation ditch is arranged between rear wall and front column, the length of heat accumulation ditch with after side equal in length within the walls, in heat accumulation ditch, be filled with charring rice husk;
Described top operational platform is arranged on the top of rear column and front column.
A prioritization scheme, described gable consists of support frame and two-layer polyphenyl foam plate, and the thickness of two-layer polyphenyl foam plate is respectively 10-12cm, and two-layer polyphenyl foam plate is fixed on support frame.
Another kind of prioritization scheme, the angle on described rear wall and ground is 75 °-80 °.
Another prioritization scheme, described polyphenyl foam plate is connected with the rear seal of scarp slope.
Further prioritization scheme, the thickness of described polyphenyl foam plate is 10-12cm.
Prioritization scheme further, the top of scarp slope is fixed in described Reflecting curtain upper end, and lower end is provided with press strip.
A concrete prioritization scheme, the spacing 2m of described rear column and front column.
A concrete prioritization scheme, the high 30cm of described waterproof platform, wide 30cm.
A concrete prioritization scheme, described heat accumulation furrow width 1.2-1.5m, dark 0.5-1m.
The present invention adopts after above technical scheme, compared with prior art, has the following advantages: greenhouse by solar heat of the present invention has improved 22.5% than the greenhouse by solar heat land utilization rate of traditional rammed earth construction body of wall.For example, the greenhouse by solar heat of long 80m, an interior span 12m, wall comprises that heat accumulation ditch takes up an area wide 2m thereafter, and thing two gables take up an area wide 0.5m, and it is 1127m that greenhouse always takes up an area face (spacing distance in two greenhouses before and after not comprising)
2, effectively soil utilizes area for 960m
2, effective use of land rate is 85.2%, and the effective use of land rate of the greenhouse by solar heat of interior span and appearance rammed earth construction body of wall is together 62.7%.
Greenhouse by solar heat of the present invention need not fetch earth in greenhouse, and cultivation bed does not dig down, builds and is not subject to Effect of Underground Water Level, promotes and is not subject to regional limits.
Greenhouse by solar heat of the present invention is provided with Reflecting curtain and heat accumulation ditch, with the greenhouse by solar heat of traditional rammed earth construction body of wall, equally has storage hot merit energy.Daytime, solar radiation arrived rear flank in back wall, by Reflecting curtain, reflexed to heat accumulation ditch, changed into heat and was preserved by the charring rice husk in ditch.Charring rice husk has the features such as the heat of absorption is large, and pyroconductivity is low.Charring rice husk stores heat daytime as much as possible, makes the temperature on fine day of greenhouse by solar heat daytime can not rise too fastly, too high; Night, sunlight room temperature lowering was fast in the winter time, and when temperature is during lower than the temperature of charring rice husk, the heat of charring rice husk discharges in warm room air, makes the temperature in greenhouse unlikely too low.
Below in conjunction with drawings and Examples, the present invention is described in detail.
