Abstract
The utility model discloses a double-film greenhouse which is characterized by comprising T-bars, an inner layer film, an outer layer film and an inflation bag. The inner layer film is laid on the T-bars, the inflation bag is formed by abreast connecting two rectangular air bags, a connection central joint of the double air bags is aligned at the T-bars to be laid on the inner layer film, and the outer layer film is laid on the inflation air bag. The T-bars are fixed on the ground through connection parts to form a greenhouse framework, and the inner layer film, the inflation air bag and the outer layer film are arranged on the T-bars to cover the greenhouse framework. The T-bars are fixed on the ground through connection parts to form the greenhouse framework, the greenhouse framework and a wall can form a flooring greenhouse, and the inner layer film, the inflation air bag and the outer layer film are arranged on the T-bars to cover the greenhouse framework. The inflation air bag is arranged between the inner layer film and the outer layer film, and the inflation air bag is made of plastic films with good light transmission. When the inflation air bag is inflated, the whole greenhouse has good light transmission and storage thermal insulation.
Description
Technical field
The utility model relates to a kind of greenhouse double film booth, especially relates to a kind of green house of laying gas cell between duplicature.
Background technology
Plastic tunnel is to be the single span arch roof structure greenhouse of cladding material with the plastic film, and plastic tunnel is general indoor does not heat, and gathers heat by greenhouse effect.Its minimum temperature is generally high 1 ~ 2 ℃ than outdoor temperature, and mean temperature is high more than 3 ~ 10 ℃.Owing to can take full advantage of solar energy, plastic tunnel has certain insulation effect, regulates temperature and humidity in the canopy within the specific limits by the volume film.It is easy, easy to use that plastic tunnel is built, and invests lessly, is the facility of a kind of easy protection ground cultivated plant.
The plastic tunnel light transmittance is generally 60% ~ 75%.For guaranteeing the whole day average light according in a basic balance, the booth plane figure mostly is the form that north and south prolongs.
Because plastic tunnel is daylighting building, so light transmittance is to estimate one of the greenhouse light transmission basic index.Light transmittance refers to the quantity of illumination in the greenhouse into and the percentage of the outdoor quantity of illumination.The greenhouse light transmittance is subjected to the influence of greenhouse printing opacity cladding material light transmission and Keelof green house shadow factor, and along with the difference of Various Seasonal solar radiation angle, the light transmittance in greenhouse is also changing at any time.The height of greenhouse light transmittance just becomes plant growth and selects the direct acting factor of plantation crop varieties.According to statistics, an existing company plastic green house light transmittance is generally at 50%-60%, and the light transmittance of glass greenhouse is at 60%-70%, and the greenhouse by solar heat light transmittance can reach more than 70%.
Improving the heat-insulating property in greenhouse, cut down the consumption of energy, is the direct approach that improves the hothouse production benefit.The insulation in greenhouse is than being a basic index weighing the greenhouse heat-insulating performance.Greenhouse heat-insulating is than referring to the ratio of the bigger greenhouse building enclosure area coverage of the less greenhouse light transmissive material area coverage of thermal resistance and thermal resistance with ground area sum.Be incubated greatlyyer than more, illustrate that the heat-insulating property in greenhouse is more good.
Green house of the prior art is that monofilm or multilayer film are laid on the keel mostly, though this booth light transmission is good, heat-insulating property is poor.
The utility model content
Technical problem to be solved in the utility model provide a kind of light transmission good, improve insulation than the greenhouse double film booth of performance.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of greenhouse double film booth is characterized in that: comprise keel, inner layer film, outer membrane and gas cell; Described inner layer film is laid on the keel, and described gas cell is that two rectangle air bags are connected to form two air bags side by side, and the connection centre joint of described pair of air bag is aimed at keel and is layered on the described inner layer film, and described outer membrane is layered on above the gas cell.
The further improvement that the utility model is done is: be fixed on ground by connector between the described keel and form big-canopy framework, described inner layer film, gas cell and outer membrane cover big-canopy framework at top of keel.Be fixed on ground by connector between the described keel and form big-canopy framework, described big-canopy framework and wall are combined into and land the greenhouse, and described inner layer film, gas cell and outer membrane cover big-canopy framework at top of keel.
The beneficial effect that adopts technique scheme to produce is: gas cell is between inner layer film and outer membrane, gas cell is to be made by the good plastic foil of light transmission, its inside is full of air, makes the existing light transmission preferably of whole booth, and stronger heat insulating ability is arranged again.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the double film booth be made up of whole skeleton in the utility model;
Fig. 2 is the structural representation of being made up of the part skeleton in the utility model that lands the greenhouse double film booth;
Fig. 3 is that inner layer film, gas cell and outer membrane are laid on the schematic cross-section at top of keel.
As shown in the figure: 1 outer membrane, 2 gas cells, 3 inner layer films, 4 keel.
Embodiment
Contrasting Fig. 1-3 pair of operation of the present utility model uses step to be described further:
Embodiment 1:
A kind of greenhouse double film booth comprises keel 4, inner layer film 3, outer membrane 1 and gas cell 2; Described inner layer film 3 is laid on the keel 4, and described gas cell 2 is that two rectangle air bags are connected to form two air bags side by side, and the connection centre joint of described pair of air bag is aimed at keel 4 and is layered on the described inner layer film 3, and described outer membrane 1 is layered on above the gas cell 2.
Be fixed on ground by connector between the described keel 4 and form big-canopy framework, described inner layer film 3, gas cell 2 and outer membrane 1 cover big-canopy framework on keel 4.
Embodiment 2:
A kind of greenhouse double film booth comprises keel 4, inner layer film 3, outer membrane 1 and gas cell 2; Described inner layer film 3 is laid on the keel 4, and described gas cell 2 is that two rectangle air bags are connected to form two air bags side by side, and the connection centre joint of described pair of air bag is aimed at keel 4 and is layered on the described inner layer film 3, and described outer membrane 1 is layered on above the gas cell 2.
Be fixed on ground by connector between the described keel 4 and form big-canopy framework, described big-canopy framework and wall are combined into and land the greenhouse, and described inner layer film 3, gas cell 2 and outer membrane 1 cover big-canopy framework on keel 4.
When laying gas cell 2, be noted that the appearance of keel 4 can not have any iron wire class lashings, because the sharp-pointed head of iron wire class lashings sweep gas cyst wall very easily makes air leak lose heat-insulating property.
