Abstract

The utility model discloses a water-saving plastic shed, aiming to provide a water-saving plastic shed which can prevent cultivated soil or water storage basins seeping water, can greatly recycle water vapor of inner air of the cultivated soil and the water storage basin, inhibits greenhouse humidity and can recycle external natural rainfall. The technical scheme includes that the top portion and plastic films on four sides of the shed are fixed on a supporting frame, a heat insulation partition curtain divides the inside of the greenhouse into a south greenhouse and a north energy storage chamber, a seepage-proofing film is arranged under cultivated soil in the greenhouse, four sides and the bottom portion of the water storage basin also fix the seepage-proofing soil with the soil, a heat insulation curtain is hung outside the energy storage chamber, and a water gathering ditch is arranged at the periphery outside the shed and communicated with the water storage basin through a conduit.

Description

The water saving plastic tunnel

Technical field

The utility model relates to plastic tunnel, especially a kind ofly can prevent seepage, containment humidity, significantly reclaim the water saving plastic tunnel of water vapour in its inner air.

Background technology

At present, plastic tunnel has obtained using widely in agricultural production, because of its function that is incubated, preserves moisture, economizes on water, makes agricultural productive force obtain huge lifting.Yet, mostly there is not impervious element under existing its farming face of plastic tunnel, simultaneously, humidity control device is comparatively effective to increasing in the booth humidity, reduces very difficulty of humidity, and that some crops is detested is wet, thereby limited the scope of application of plastic tunnel.

Summary of the invention

In order to overcome the deficiency in the above-mentioned technology, the utility model provides a kind of water saving plastic tunnel, and it has the seepage of preventing, containment humidity significantly reclaims the function of water vapour in its inner air and outside natural rainfall.

The technical scheme that its technical problem that solves the utility model adopts is: its top and four side plastic films are fixed on the bearing support, insulation hangs on the bearing support every curtain, and the greenhouse in south and the accumulation chamber on the north will be divided in the canopy, accumulation chamber is 1: 3～9 with the area ratio in greenhouse, the curtain seam makes the greenhouse communicate with accumulation chamber, cultivated soil bottom is lined with antiseepage film in the greenhouse, antiseepage film tilts to cistern, gradient i=1～2%, accumulation chamber is provided with cistern, and cistern four sides and bottom are also with antiseepage film and soil fixation, and accumulation chamber is linked with heat holding curtain outward, be provided with collecting ditch around canopy is outer, be communicated with cistern by conduit.

The beneficial effects of the utility model are, can prevent the infiltration of cultivated soil and cistern, can significantly reclaim water vapour in its inner air, the containment chamber humidity, and can reclaim its outside natural rainfall, water-saving result is remarkable.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

At Fig. 1, in embodiment illustrated in fig. 2, its top and four side plastic films 2 are fixed on the bearing support 1, insulation hangs on the bearing support 1 every curtain 4, and its inside is divided into the greenhouse 3 in south and the accumulation chamber 6 on the north, accumulation chamber 6 is 1: 4 with the area ratio in greenhouse 3, curtain seam 5 makes greenhouse 3 communicate with accumulation chamber 6, cultivated soil 12 bottoms are lined with antiseepage film 11 in the greenhouse 3, antiseepage film 11 tilts to cistern 10, gradient i=1.5%, in the remittance cistern 10 that catchments that oozes down in the cultivated soil 12, cistern 10 is located in the accumulation chamber 6, and cistern 10 4 sides and bottom are also fixing with soil 13 with antiseepage film 11, the accumulation chamber 6 outer heat holding curtains 7 that are linked with, be provided with collecting ditch 8 around the present embodiment, compile the outer natural rainfall of canopy, and import in the cistern 10 by conduit 9.Daytime is when shining upon, temperature rises rapidly in the greenhouse 3, air themperature strengthens, and accumulation chamber 6 is because of heat holding curtain 7, insulation is every the insulation effect of curtain 4, it is big to add in the cistern 10 specific heat of water, therefore accumulation chamber 6 thermal inertias are big, it is slow to heat up, and forms the big temperature difference with greenhouse 3, and damp-heat air rises in the greenhouse 3, guiding via the skewed plastic film 2 in top, enter accumulation chamber 6 through insulation every curtain 4 top curtain seams 5 again, the part water recovery becomes water to import cistern 10, air themperature, humidity all descends, and sink, flow back to greenhouse 3 through insulation every curtain 4 bottom curtain seams 5 at last.

Claims

One kind the water saving plastic tunnel, it is characterized in that: its top and four side plastic films are fixed on the bearing support, insulation hangs on the bearing support every curtain, and the greenhouse in south and the accumulation chamber on the north will be divided in the canopy, accumulation chamber is 1: 3～9 with the area ratio in greenhouse, insulation all has the curtain seam up and down every curtain, cultivated soil bottom is lined with antiseepage film in the greenhouse, antiseepage film tilts to cistern, gradient i=1～2%, and accumulation chamber is provided with cistern, cistern four sides and bottom are also with antiseepage film and soil fixation, accumulation chamber is linked with heat holding curtain outward, is provided with collecting ditch around canopy is outer, is communicated with cistern by conduit.
