Abstract
The utility model discloses a longspan internal heat preservation double-layer plastic film-covered greenhouse, which belongs to the modern agricultural facilities construction field. The utility model is designed for overcoming the defects of low land utilization ratio and bad heat preservation performance of the traditional greenhouse in northwestern territories. A greenhouse framework mainly consists of an internal steel framework, an external steel framework and upright posts. An external layer adopts the double string framework and is covered with a thin film. An internal layer consists of the internal framework, a thin film, a guy wire-type curtain rolling machine and an insulating quilt. The internal framework adopts a single framework structure. The curtain rolling machine is arranged on a curtain rolling machine support which is arranged in the middle part of the top of the internal framework. A row of cement piers are arranged in the middle position of the greenhouse for installing the upright posts. The utility model has the advantages that: 1 low temperature effect around the greenhouse is reduced and land utilization ratio is improved, 2 the wind and snow resistant capability of the greenhouse is improved and at the same time, the heat preservation performance of the greenhouse is improved through the internal film insulating quilt, 3 the insulating quilt is arranged internally, therefore dismantlement is not needed, and time, labor and money are saved, and 4 a heat insulating layer between the two layers reduces great climatic change and is favorable to the melting of accumulated snow.
Description
Technical field:
The present invention relates to a kind of interior insulation double-plastic booth of large span, this plastic tunnel can increase the temperature in the canopy, greatly improves the thermal isolation and heat storage ability of plastic tunnel, belongs to modern installations agricultural engineering technology field.
Background technology:
In the agricultural facility plantation, utilizing all types of plastic booth to carry out off-season cultivation has been convention at present, but there is following drawback in present existing plastic tunnel:
(1) though existing booth one side land utilization rate can reach more than 90%, owing to be subjected to the influence of marginal effect, the critical zone of scope 1m is in low-temperature condition for a long time around the booth, is unfavorable for plant growth.The span of common booth is generally 6-12m in addition, and the climatic variation amplitude is big in the canopy, especially booth around, be not suitable for the growth of crop, so the actual land utilization rate of booth is not high.
(2) common booth need cover with insulation materials such as thermal insulation quilts night, but because thermal insulation quilt is outer cover type, this mode requires it to have water-proof function, thereby cause booth cost height, air between the air on thermal insulation quilt surface and the thermal insulation quilt slit directly links to each other in addition, is subjected to the influence of natural environments such as wind speed, and the heat on booth surface is fast to extraneous transfer rate, winter minimum temperature is only 4-6 ℃ in the booth, and the integral heat insulation effect is relatively poor.
(3) at snowfall in winter and NORTHWEST CHINA area dusty wind weather, the accumulated snow and the grains of sand all are deposited in the thermal insulation quilt surface, have both reduced the heat-insulating property of thermal insulation quilt, have increased unnecessary hand labor again, not only waste a large amount of hand labor power, but also increased potential safety hazard.
(4) existing booth is provided with canopy in a plurality of arches in order to heat in interior canopy, needs to leave a plurality of passageways between the interior canopy, has not only dwindled cultivated area, has also increased area of dissipation, and canopy temperature at night is low excessively in causing, and is unfavorable for the thermophilous growth.Quick heating in the canopy on daytime has formed the large tracts of land high-temperature area in addition, is unfavorable for liking cool plant growth.
(5) thermal insulation quilt of existing plastic tunnel all needs dismounting annual spring, and install autumn, both wasted a large amount of human resources, increased preservation thermal insulation quilt process safe hidden danger again.
Summary of the invention:
The objective of the invention is to overcome the deficiencies in the prior art, adopt large span to improve land utilization rate on the one hand, alleviate the big shortcoming of marginal climatic variation amplitude in the canopy, improve the cultivated area of crop, covered by duplicature by built-in heat insulation on the other hand, improve the heat insulation effect of booth, liner type air between the canopy film is as cushion space, both helped improving the booth nocturnal temperature, can in time reduce the area of high-temperature area on daytime again, can also in time dissolve the accumulated snow of outer canopy in addition in the winter time by the temperature of interior canopy, save the labour, alleviate load.Therefore emphasis of the present invention provides a kind of efficiently utility model plastic tunnel easily, this plastic tunnel Winter protection performance is good, summer booth innerly keep nice and cool, improve the service life of thermal insulation quilt simultaneously and do not need dismounting throughout the year.
Technical scheme: the insulation double-layer plastic film covers booth in a kind of large span, it is characterized in that: wall is established in north and south, form by inside and outside two-layer steel skeleton and column, outer skeleton adopts two string skeletons, cover film outward, interior canopy is made up of inner frame, film and roller shutter machine and thermal insulation quilt, and inner frame adopts the monoskeleton structure, the roller shutter machine is installed on the roller shutter machine support of inner frame ceiling middle part, and the booth interposition installs row's clump and is used to install column.
Two fans are installed respectively on the body of wall of north and south are produced door, the pre-buried clump in booth bosom position makes things convenient for the installation of column, and the roller shutter machine adopts left and right sides stay-supported structure, is placed on the interior canopy skeleton roller shutter machine support.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
(1) by increasing the span and the length of booth, land utilization rate is brought up to more than 90%, and alleviated the marginal cryogenic effect around the booth, increased cultivated area; (2) adventitia covers the anti-blown sand ability that has improved whole booth, is adapted to NORTHWEST CHINA portion area; Inner membrance is added a cover thermal insulation quilt, make winter temperature of shed than before double-deck booth improve 4-8 ℃, can satisfy NORTHWEST CHINA portion area warm season vegetable safety substantially and pass the winter; (3) because the protection of outer canopy film, can prolong 2-3 the service life of thermal insulation quilt, need not dismantle throughout the year in addition, but about 40 of savings of labor; (4) the buffering liner type thermal insulation layer between the canopy film can be alleviated the amplitude of extraneous climatic variation, improve the booth nocturnal temperature, can in time reduce the area of high-temperature area on daytime again, moreover the accumulated snow in winter can be dissolved in time by the temperature of interior canopy, save the labour, alleviate load.
