Abstract

The utility model relates to an sunlight greenhouse with two-layer films, wherein, the entire greenhouse is circular arch-shaped with the frame construction composed of a steel tube framework and iron wire lacing wires; the interlayer which is formed by an inner and an outer plastic films has ideal closeness effect so as to reduce thermal convection and conductance between the inside and the outside of the greenhouse to a low degree. The utility model adopts novel heat insulating material to replace wall body, thereby obtaining higher utilization rate of sunlight and ideal heat preservation effect to save energy source and material; meanwhile, the utility model realizes easy adjustment of temperature and humidity.

Description

The duplicature energy saving sunlight greenhouse

The utility model relates to a kind of greenhouse by solar heat, especially the double-plastic energy saving greenhouse.

At present, the greenhouse by solar heat of steel frame construction generally is to build a wall in the back, the top covers with layer of plastic film, winter is in order to reach heat insulation effect, employing is built up the greenhouse wall thickness more than 50 centimetres, and the way of bedding straw screen or mat on plastic film so not only takies more arable land, the effort of taking a lot of work, heat insulation effect is unsatisfactory.Because existing hothouse framework structural design is reasonable inadequately, has wasted a large amount of building materials, steel, has increased construction cost.

The purpose of this utility model provides the rational more novel greenhouse of a kind of structure, and it can not only effectively utilize the arable land, reduces labour intensity, reduce construction investment, and, higher day light utilization efficiency had, heat insulation effect is good, saves the energy and opens money, the ventilation convenient temperature control.

The purpose of this utility model is achieved in that the overall structure in greenhouse, be designed to arch-shaped, constitute frame structure by steel pipe skeleton and iron wire lacing wire, both sides are laid layer of plastic film respectively inside and outside skeleton, at skeleton installed inside draw-in groove, cooperate the jig spring, can very easily inboard plastic film be fixed up, inboard film and outside film form an airtight interlayer.Internal layer membrane is dismounting as required, and film base, the outside can open-ventilating in summer.Between the double-layer films of the in the shade side in greenhouse, place thickness at the plastic foamboard more than 3 centimetres.Utilize the characteristics of plastic foamboard easy accessibility, can regulate the height and the thickness of placement flexibly, reach as high as the center of arch circular top part in Various Seasonal.Be connected to form an integral body with the iron wire lacing wire between skeleton of the present utility model, spacing can be set to 3-8 rice between skeleton, even wideer.

Owing to take such scheme, the formed interlayer of ectonexine plastic film has good obturation effect, dry air thermal conductivity factor in the interlayer is very low and do not produce convection current, makes inside and outside thermal convection current in greenhouse and heat conduction drop to very low degree, plays good insulation effect.Inner plastic film disassembled and assembled freely, the outer layer plastic film both sides can be provided with ventilating opening arbitrarily, make the easier adjusting of temperature, humidity in the greenhouse, can solve common greenhouse is difficult for cooling in summer a difficult problem preferably.Use the tension force of iron wire lacing wire, outer layer plastic film is supported, improved the resistance to compression and the wind resistance effect in greenhouse simultaneously, utilize less skeleton, just can reach the designing requirement in greenhouse, compare, can reduce the usage amount of steel with the situation of about 1 meter of common Keelof green house spacing.

Below in conjunction with drawings and Examples the utility model is further specified.
