Abstract
The utility model belongs to the technical field of agricultural facility, in particular to a thermal insulated curtain air cushion type flexible sealer of plastic cover greenhouse, sunlight film greenhouse and multi-span film greenhouse, is composed by thermal insulated curtain shaft bars, enclosed air bags, a thermal insulated curtain, an air supply pipeline, an air supply pump, greenhouse roof truss girders, and traction ropes. 2-30 greenhouse roof truss girders are provided, and adjacent greenhouse roof truss girders are parallel to each other. One end of the thermal insulated curtain is fixed on the greenhouse roof truss girders, and the other end is fixed on appropriate thermal insulated curtain shaft bar. 2-20 traction ropes are provided, and one end of each traction rope connects with the thermal insulated curtain shaft bar which is dragged by the traction rope. Enclosed air bags are provided between the thermal insulated curtain shaft bar and adjacent greenhouse roof truss girder, and the enclosed air bags connects with the air supply pump. The present utility model avoids the requirements of close contact between the thermal insulated curtain shaft bar and the multi-roof truss girders of multi-span greenhouse in existing structure, allows a clearance, adopts enclosed air bags which are convenient for air charging with high elasticity to reduce manufacturing precision.
Description
Technical field
The utility model belongs to the industrialized agriculture technical field, is specifically related to a kind of plastic tunnel, daylight plastic greenhouse and Lian Dong plastic greenhouse inside thermal screen curtain flexible seal device.
Background technology
Along with agricultural modernization advances, the development of industrialized agriculture, plastic tunnel, daylight plastic greenhouse and Lian Dong plastic greenhouse become modern agriculture and produce critical facility, China's plastic tunnel, daylight plastic greenhouse and Lian Dong plastic greenhouse amounted to 2,000,000 hectares in 2004, the insulation curtain effectively reduces heating volume 1/3 in all kinds of plastic greenhouses, its gap sealing effectiveness influences the greenhouse energy loss, effective seal can reduce energy loss 8～10%, and greenhouse heat-insulating curtain hermetically-sealed construction is one of the technical problem that must consider and solve.
Successfully reduce indoor heat insulating curtain gap energy loss at plastic tunnel, daylight plastic greenhouse and Lian Dong plastic greenhouse, social benefit is huge.External and domestic colleague in greenhouse design and product development, usually adopt steel wire rope scrolling or tooth bar to promote the insulation film pull bar and closely contact sealing with roof truss, it is long apart from seal request between many to satisfy multirow simultaneously, and the transmission and the structure accuracy of manufacture are had relatively high expectations poor stability.
Summary of the invention
The purpose of this utility model is to propose a kind of company simple in structure, with low cost plastic greenhouse insulation curtain air-cushion type flexible seal device.
The company that the utility model proposes a plastic greenhouse insulation curtain air-cushion type flexible seal device is formed (its structure as shown in Figure 1, 2) by insulation curtain axostylus axostyle 1, gas-flow closure bag 2, insulation curtain 3, steam line 4, air feed pump 5, greenhouse roof truss beam 6, pull rope 7.Greenhouse roof truss beam 6 has N, and adjacent greenhouse roof truss beam 6 is parallel to each other, one side insulation curtain 3 be fixed in greenhouse roof truss beam 6, another side is fixed in corresponding insulation curtain axostylus axostyle 1; Pull rope 7 has the 2-20 root, and an every end that involves messenger 7 connects insulation curtain axostylus axostyle 1, and insulation curtain axostylus axostyle 1 affects by pull rope 7; Be provided with gas-flow closure bag 2 between insulation curtain axostylus axostyle 1 and the adjacent greenhouse roof truss beam 6, gas-flow closure bag 2 connects air feed pump 5 by steam line 4.
In the utility model, the quantity of greenhouse roof truss beam 6 is decided on number between the greenhouse, and each greenhouse is provided with a greenhouse roof truss beam 6, and the common greenhouse roof truss beam N that adopts is 2-30.
In the utility model, gas-flow closure bag 2 can adopt vinyl plastics to make.
The course of work of the present utility model is as follows: an end of insulation curtain 3 is fixed on the greenhouse roof truss beam 6, and the other end is fixed on the insulation curtain axostylus axostyle 1, moves by pull rope 7 traction insulation curtain axostylus axostyles 1.During use, air feed pump 5 is inflated to the gas-flow closure bag 2 that is fixed on the corresponding greenhouse roof truss beam 6 by steam line 4, gas-flow closure bag 2 has been filled up the gap of leaving between greenhouse roof truss beam 6 and the insulation curtain axostylus axostyle 1, makes between insulation curtain pull bar 1 and the roof truss to seal.
The utility model has changed existing structure with the technical method that closely contacts sealing, closely contacts requirement between the roof truss between having avoided insulation curtain axostylus axostyle and attached-greenhouse being more than many, allows to leave the gap, utilizes inflatable seal band flexible sealing, reduces the accuracy of manufacture.Use the utility model attached-greenhouse long apart from insulation curtain axostylus axostyle with more than many between between the roof truss, adopt convenient, the big flexible gas-flow closure bag of air feed, realize sealing.
