Abstract
The utility model relates to a plastic shed, which is characterized in that: the plastic shed comprises a shed frame and a plastic greenhouse film arranged on the shed frame; the characteristic is that the top and bottom of the shed frame are respectively provided with a plastic sealing groove, the plastic greenhouse film is respectively fixed by rubber sealing strips in the top and bottom of the sealing groove. The sealing groove and sealing strips structure arranged by the utility model make the plastic shed form double layers shed-film structure, which can not only save energy and have good thermal insulation performance, but also is convenient to install and operate, with simple and resilient structure; the utility model can be extensively used in the process of culturing various crops.
Description
The utility model relates to a kind of greenhouse by solar heat, particularly saves the plastic tunnel of the energy about a kind of high insulating effect.
Existing plastic tunnel generally all is to adopt monolayer plastic canopy film, and individual layer canopy film heat-insulating property is poor, easy frosting dewfall, and especially at north cold area, the requirement that the plastic tunnel of this individual layer canopy film does not often reach crop growth.For addressing this problem, people have taked various measures, such as: adopt double-layer inflated film, it can completely cut off cold air preferably.But the material require of this aerated film is withstand voltage properties preferably, so material cost is than higher, simultaneously because gas leaks is unavoidable, therefore must ceaselessly inflation in 24 hours, and very waste energy.
At the problems referred to above, the purpose of this utility model provides a kind of simple in structure, and cost is low, good heat insulating, and the while is saved the plastic tunnel of the energy again.
For achieving the above object, the utility model is taked following design: a kind of plastic tunnel, it comprises big-canopy framework and the plastic greenhouse film that is arranged on the described big-canopy framework, it is characterized in that: top and bottom at described big-canopy framework are respectively arranged with the plastic seal groove, are fixed with described plastic greenhouse film with rubber weather strip respectively in the described seal groove of top and bottom.
Described plastic seal groove can be arranged on to section gap on each longitudinal beam of described big-canopy framework.
The cross sectional shape of described plastic seal groove can be a circular arc, and the cross sectional shape that is mated the described rubber weather strip of use can be circular.
The utility model is owing to take above design, it has the following advantages: 1, the utility model is owing to top and diapire at big-canopy framework are provided with the plastic seal groove respectively, and double-layer plastic canopy film is separately fixed in the seal groove of top and bottom with rubber weather strip, therefore make plastic tunnel form double-deck canopy film, it not only has good heat-insulating property, and simple in structure flexible, fitting operation is very convenient.2, the utility model need not increase charger owing to still adopt common plastics canopy film to form double-deck canopy membrane structure, and therefore, the cost of material is low, and operating cost is also low, not only saves the energy, and easy to maintenance.3, therefore the utility model makes the fixing stressed uniform tension of plastic greenhouse film good because plastic seal groove section gap is arranged on each longitudinal beam of big-canopy framework, neatly and not influences the light irradiation.The utility model can be widely used in various farmings with in the cultivation process, can also be used for other various greenhouse structures.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is the utility model structural representation
Fig. 2 is the utility model scheme of installation
As shown in Figure 1 and Figure 2, the utility model comprises crisscross big-canopy framework 1, its be arranged on brick or booth bases 2 such as metallic support or legs on, top and bottom at big-canopy framework 1 are fixed with plastic seal groove 3 respectively, in the seal groove 3 of top and bottom, use sealing strip 4 fixed plastics canopy films 5 respectively.Thereby, form double-deck canopy film 5 up and down respectively in the top and the bottom of big-canopy framework 1.
The foregoing description and schematic diagram only are to be explanation the utility model, and should not limit protection domain of the present utility model, because its various structures all can change.Such as:
The groove inner structure of plastic seal groove 3 can be a circular arc, and the cross sectional shape of the sealing strip 4 that cooperates with seal groove 3 can be circular.The cross sectional shape of seal groove 3 and sealing strip 4 also can be wedge shape or other concaveconvex shape.
Various materials and planform that the structure of big-canopy framework 1 can be, particularly can adopt the design people is disclosed in 00246440.3 utility model patent " big plastic hot-shed with it " structure in the patent No..
