Description

A crawler-type greenhouse roof composite insulation layer

Technical field

The utility model relates to a crawler-type greenhouse roof composite insulation layer and relates to the technical field of agricultural planting and breeding.

Background technique

During the planting process of the greenhouse in winter, there is no sunlight and the temperature is relatively low at night. It is generally necessary to cover the roof film with an insulation quilt at night. A rolling shutter machine is used to curl it up during the day and spread it at night to reduce the amount of heat inside the greenhouse. Loss of heat. Keeping the greenhouse warm and storing it well, and adding coverings around the greenhouse are necessary insulation measures for greenhouses in winter.

At present, the commonly used greenhouse film covering insulation materials at night in winter are nothing more than straw curtains, insulation blankets, insulation quilts and other materials as insulation coverings. The common feature of this type of insulation covering is that it can be rolled on the greenhouse film according to needs through a rolling curtain machine. The top can be curled or stretched to meet the needs of night heat preservation or daytime lighting - the curling and unfolding properties are good. At the same time, another common disadvantage is that materials such as straw curtain insulation felt have a low thermal insulation coefficient, large heat dissipation, poor energy saving, and the thermal insulation effect is far inferior to low-priced insulation boards with excellent thermal insulation effects. Straw mat curtains have the worst thermal insulation performance. The thermal coefficient of insulation felt is 0.1--0.3W/(m2·K). The thermal conductivity of rigid extruded polystyrene board of the same thickness is 0.028-0.032W/(m2·K). Those with better thermal insulation performance are similar to phenolic boards, polyurethane foam boards, polyethylene boards, etc. The thermal conductivity is as low as foamed polyurethane, 0.020~0.024W/(m2·K), and the cheapest expanded polystyrene board has a thermal conductivity It can also reach 0.039W/(m2·K), which is much higher than that of materials such as straw curtains and insulation blankets. Moreover, this type of hard insulation board is also cheap, and its thermal insulation effect is more than ten times that of straw curtains and insulation blankets. , or even dozens of times the thermal insulation effect, which can greatly reduce heat dissipation (because of the huge area of the shed film, the energy-saving effect is particularly obvious); the existing rigid insulation board suffers from its size of 1 meter to 3 meters and cannot be used like straw curtains and linoleum. That way the canopy can be rolled or unfolded freely.

The usage effect of this utility model is explained as follows:

The thermal conductivity of the insulation slats used in the crawler-type insulation slat layer 102 is less than 0.024w/㎡·k. The crawler-type greenhouse roof composite insulation layer 1 is on the greenhouse membrane 2, and passes through the rolling curtain similar to a conventional insulation blanket. The machine rolls up along the roller 201 of the roller shutter machine, that is, the crawler greenhouse roof composite insulation layer 1 is rolled or rolled up along the roller 201 under the action of the roller shutter machine; it is rolled or rolled on the surface of the greenhouse film 2 as needed. , the soft connection layer 101 is always in soft contact, and the crawler-type insulation slat layer 102 will not scratch the greenhouse film 2; during the process of spreading or curling, there is no need to make any changes to the original mechanical structure of the greenhouse film.
