CN2314576Y - Thermal insulation layer for heat reflection - Google Patents

Abstract

The utility model relates to a thermal insulation layer for heat reflection, which comprises a thermal insulation layer with integrally connected both ends that can curl guide tracks, and a guide groove. The utility model is characterized in that the thermal insulation layer comprises a plurality of layers that are fixedly connected by connecting belts. The utility model has the advantages of favorable thermal insulating property, reasonable and scientific structural design, convenient curling and expanding operations, less time and labor cost, longer illumination time and neat appearance.

Description

The heat reflection heat-insulation layer

The utility model belongs to a kind of insulation construction of greenhouse by solar heat, particularly a kind of heat reflection heat-insulation layer.

At present rural development many planting vegetables and do the heat preservation greenhouse of breed, its insulation canopy face is to cover layer of plastic film on skeleton, daylight can penetrate to make in the canopy and heat up daytime, be incubated and need cover straw screen or mat night, like this, all need in early morning every day and night to spend at least 2 hours time, carry out roller shutter and put curtain, time-consuming, effort have also shortened the light application time in the canopy.For this reason, the applicant had once developed a kind of " greenhouse by solar heat insulation canopy face structure " (number of patent application is 97234158,4), had cancelled the covering straw screen or mat, and was time saving and energy saving, prolonged light application time.But the deficiency that exists is that heat insulating ability is relatively poor.

The purpose of this utility model provides a kind of heat reflection heat-insulation layer, and good heat preservation performance is curled and launched easy and simple to handlely, time saving and energy saving, prolongs light application time, and outward appearance is clean and tidy.

The purpose of this utility model is to realize like this; It comprises the whole connection in two ends can the curl heat-insulation layer and the guide groove of guide rail, and its technical scheme main points are: heat-insulation layer is a sandwich construction, affixed connecting band between each layer.

The outer plating infrared-reflecting layers of above-mentioned heat-insulation layer.

The utility model has the advantages that: good heat insulating, scientific structure design is reasonable, helps realizing industrialized production in agriculture production, curls and launches easy and simple to handlely, time saving and energy saving, prolongs light application time, and outward appearance is clean and tidy.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model.

End face structure schematic diagram when Fig. 2 is the utility model expansion.

Fig. 3 is the mounting structure schematic diagram of guide groove and guide rail.

See Fig. 1-3, concrete structure is as follows; Heat-insulation layer 3 is connected and composed by 2 heat seals of plastics connecting band by plural layers, the uniform setting of connecting band; The outer membrane 6 plating infrared-reflecting layers of heat-insulation layer 3, ground and plant reduce heat-energy losses to the far infrared of aerial radiation in the reflection canopy to reach.For the ease of installing and using, several cell width are adopted in the heat-insulation layer aggregate erection, and present embodiment design cell width is 1 meter.The whole plastic guide rail 7 that can curl that connects in each two ends, unit of heat-insulation layer 3, the cross section of guide rail 7 is rounded.Guide rail 7 slides and is inserted in the guide groove 5.Guide groove 5 connects with the overarm 1 of big-canopy framework and gets final product by connecting clamp 4.Use principle: morning, each layer film was fitted together when heat-insulation layer was curled, and slided and curled to an end; Evening, each layer film separately formed the immobilising air layer of multilayer automatically owing to the gravity reason, stops indoor heat loss when launching to cover, thereby realized the purpose of insulation.

Claims (2)

1, a kind of heat reflection heat-insulation layer, it comprises the whole connection in two ends can the curl heat-insulation layer and the guide groove of guide rail, it is characterized in that: heat-insulation layer is a sandwich construction, affixed connecting band between each layer.

2, heat reflection heat-insulation layer according to claim 1 is characterized in that: the outer plating infrared-reflecting layers of heat-insulation layer.
