A kind of solar greenhouse wall body structure
Technical field
The utility model relates to agricultural structure technical field of structures, especially a kind of solar greenhouse wall body structure.
Background technology
In recent years, along with improving constantly of people's living standard and material requisite, people there occurs great variety to food security consciousness and to eating patterns consciousness, and the demand of market to greengrocery food grows with each passing day.The large pillar industry that industrialized agriculture has become prosperity local economy and increased farmers' income.And as vegetables off-season cultivation ground greenhouse by solar heat, also significant progress and raising is obtained, greenhouse by solar heat is the subenvironment of growing vegetables, greenhouse by solar heat only accomplishes scientific and reasonable construction, the demand of vegetable growth to environmental condition could be met, raise labour efficiency, avoid freezing cold disaster accident and occur, reach the temperature of vegetables reasonable growth, light, water, gas, fertile condition.
For a long time, the wall construction of greenhouse by solar heat is mainly based on various lighttight house with tamped clay walls cob wall and brick wall structure, main dependence front roof non-transparent covering material carries out daylighting and ventilation, carry out insulation in night by covering the insulation material such as straw screen or mat or thermal insulation quilt, body of wall, ground and air accumulation of heat maintain greenhouse evening temperature.This greenhouse by solar heat is in order to ensure the heat-insulating property in winter, often to build the rear roofing of certain length, although improve the heat-insulating property of Winter Solar Greenhouse, but the shading of Hou Qiang and rear roofing, greenhouse by solar heat Background Region intensity of illumination is caused significantly to reduce, the photosynthesis of rear portion, greenhouse crop is unfavorable for very much, also suppresses the normal growth of crop.By observation, the intensity of illumination at this greenhouse by solar heat rear portion is only 60% of front portion.After entering spring, how retain the thermal and insulating performance of Hou Qiang, rear roofing in cold season, and can allow other season rear roofing and body of wall become transparent can daylighting body of wall, increase the lighting quantity in greenhouse, promoting the photosynthesis of plant, is exactly problem to be solved by this invention.

Embodiment
Be described in detail the utility model below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection domain of the present utility model.
A kind of solar greenhouse wall body structure as shown in Figures 1 to 3, is mainly used on rear side of greenhouse and the gable of the left and right sides, comprises outer transparent panel 3, inner layer transparent plate 4, sucktion fan 6, external wall skeleton 1 and inside wall skeleton 2,
Outer transparent panel 3 and inner layer transparent plate 4 standing opposite apart 0.2 meter, the space end sealing between outer transparent panel 3 and inner layer transparent plate 4,
Sucktion fan 6 is fixed on outer transparent panel 3 top, and air exhauster one end is stretched in the space between outer transparent panel 3 and inner layer transparent plate 4,
Many inside wall skeleton 2 is uniformly distributed along inside wall transparent panel 4, horizontal apart from the plate face of side far away, outer transparent panel 3 position, and every bar inside wall skeleton 2 vertically extends bottom and is fixed in ground,
Many external wall skeleton 1 is uniformly distributed along external wall transparent panel 3, horizontal apart from the plate face of side far away, inner layer transparent plate 4 position, and every bar external wall skeleton 1 vertically extends bottom and is fixed in ground.
Inside wall skeleton 2 and external wall skeleton 1 are zinc-plated square steel supporting, and during installation, spacing is 0.9 meter between each inside wall skeleton 2 and between each external wall skeleton 1.
Be bending in the middle part of outer transparent panel 3 and inner layer transparent plate 4 cross section, when the utility model is used for gable, can not arrange this bending, when the utility model is used for rear wall of greenhouse, then bending makes the utility model form Hou Qiang and rear roof simultaneously.
Multiple software particle 5 structure is filled in the space that outer transparent panel 3 and inner layer transparent plate 4 are formed.
The software particle 5 of the filled suction of filling is polystyrene foam particles, polyethylene foamed etc.
When building greenhouse by solar heat, use aluminum strip compacting again with after rubber belt sealing between both sides gable and the outer transparent panel 3 of rear wall and between the inner layer transparent plate 4 of both sides gable and rear wall, finally fix with self-tapping screw solid.
During use, when winter temperature is lower, fill software particle 5 by space between sucktion fan 6 outer layers transparent panel 3 and inner layer transparent plate 4, in the present embodiment, software particle 5 is polystyrene foam particles.When outside air temperature raise do not need body of wall to be incubated time, utilize sucktion fan 6 to extract polystyrene foam particles, allow the crop planted in greenhouse fully carry out photosynthesis.
After the polystyrene foam particles filler that back wall and rear roofing extract in transparent panel, the illumination particularity in the utility model greenhouse by solar heat and common cob wall, brick wall greenhouse by solar heat are completely different.Illumination particularity in common greenhouse by solar heat is that anterior illumination condition is best, takes second place in middle part, and rear portion illumination only has 60% of the anterior intensity of illumination in greenhouse, as shown in Figure 4.The illumination particularity applied in greenhouse by solar heat of the present utility model is, as shown in Figure 5, rear portion, greenhouse is the highest, take second place in front portion, middle part is minimum, but Nei Ge position, greenhouse intensity of illumination difference is little, do not have common greenhouse by solar heat difference so obvious, illumination patterns is more even.Analyzing causes the principal element of this result to be, apply intensity of illumination the blocking due to Keelof green house in the middle part of greenhouse by solar heat of the present utility model, cause the reduction of intensity of illumination, and front portion is due to light direct projection, block less, the impact of skeleton on illumination is less, and not only there is the direct sunlight of front roof at rear portion, and have and supplemented by the scattered light of rear roofing and back wall, so the intensity of illumination at rear portion, greenhouse is the highest.By above observation and analysis, sufficient proof applies the intensity of illumination that greenhouse by solar heat of the present utility model effectively can improve greenhouse by solar heat rear portion, improves photosynthetic crop, promotes the growth of crop.
A kind of solar greenhouse wall body structure of the utility model, can fill according to seasonal variation according to its structural design or extract polystyrene foam particles out, plant growth needs are met according to condition to change temperature and light in greenhouse, avoid due to Hou Qiang and rear roofing shading, the greenhouse by solar heat Background Region intensity of illumination caused significantly reduces, and is unfavorable for the problem of the normal growth of crop.
