Abstract

The utility model relates to a sunshade heat preservation system in a greenhouse. The system comprises an upright post, three layers of girder grillages, drive mechanisms, driving shafts, a fixed bracket, push-and-pull rods, an axle shaft gear, a draw curtain rack and pinion, and curtains; wherein, the three layers of girder grillages are installed at the upper end of the upright post, and each layer of the girder grillages is fixedly provided with the drive mechanism and the driving shaft and is provided with the push-and-pull rods being vertical to the girder grillages by the fixed bracket; the axle shaft gear is arranged on the driving shaft and is meshed with a gear of the draw curtain rack and pinion fixedly arranged on the girder grillage; and the push-and-pull rods are fixedly provided with the curtain by curtain support wires. The system has the advantages that the heat loss of terrestrial radiation of the greenhouse can be effectively prevented in winter, and the thermal energy consumption is reduced; when in summer, part of sunlight can be reflected by an internal sunshade curtain, and the sunlight can be diffused into the greenhouse to evenly irradiate the plate, so that the crops are protected from being burnt by bright light; meanwhile, the temperature of the greenhouse can be reduced by 4-6 DEG C, so that the running cost of the greenhouse can be greatly reduced. The sunshade heat preservation system also can prevent the indoor water vapor from overflowing outside without limit, thus effectively maintaining the air moisture, reducing the irrigation water, prolonging the harvesting time of crops and achieving the effects of increasing crop yield and improving the crop quality.

Description

Greenhouse internal sunshade heat-insulation system

Technical field

The utility model belongs to the chamber facility field, particularly relates to a kind of greenhouse internal sunshade heat-insulation system.

Background technology

Along with improving constantly of agriculture requirement, to medium-to-high grade company plastics or glass greenhouse structural development, it is more and more general that the practicality of greenhouse sunshade and heat-insulation system also becomes from simple single booth structure for the greenhouse kind.At present, the internal sunshade system of attached-greenhouse is double-deck truss structure and two-layer sunshade curtain, though can playing, two-layer sunshade curtain reduces light transmittance, the sunburn degree that reduces flowers and the effect of cooling in summer, but because various flower growth condition differences, some flowers need grow under the long environment of light application time, and some flowers shade tolerance is strong, then likes growing under shady and cool environment, therefore, above-mentioned greenhouse internal sunshade system is difficult to satisfy the flower growth requirement of different light time and condition.In weather colder winter, the double-deck curtain in greenhouse can't play insulation effect, can not satisfy the optimal temperature of plant or flower growth needs; Especially in the time of need keeping higher greenhouse internal temperature at cloudy day and night, need outfit heating equipment, not only increased equipment investment and energy resource consumption, and strengthened greenhouse operating cost.

Summary of the invention

The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, cheap and effectively protective plant exempt from the greenhouse internal sunshade heat-insulation system that the radiations heat energy loss was burnt, also can be reduced to high light.

The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: greenhouse internal sunshade heat-insulation system, comprise column, truss, driving mechanism, pull bar, draw curtain rack-and-pinion and curtain, it is characterized in that: the column upper end is equipped with three layers of truss, install driving mechanism and driving shaft on every layer of truss, and perpendicular pull bar is installed by analog bracket, axle shaft gear is housed on the driving shaft, axle shaft gear is meshed with the gear of draw curtain rack-and-pinion on being packed in truss, is fixed with curtain by shade supporting wire on each pull bar.

The utility model can also adopt following technical scheme:

Be fixed with greenhouse internal sunshade curtain by shade supporting wire on the described upper and lower pull bar, be fixed with the greenhouse heat-insulating curtain on the middle pull bar.

Described greenhouse internal sunshade curtain and insulation curtain all are connected with aluminium alloy and drive the limit.

Described insulation curtain is an aluminium foil high-strength polyester yarn braiding structure.

Advantage and the good effect that the utlity model has are: because the utility model adopts three layers of truss and three layers of curtain structure, can prevent effectively that in the winter time greenhouse terrestrial surface radiation heat runs off, and reduces heat exhaustion; In summer, the internal sunshade curtain can reflect away part sunlight, and makes the sunlight diffusion enter the greenhouse, the uniform irradiation plant, and cover crop exempts from high light and burns, and greenhouse temperature is descended 4 ℃～6 ℃, reduces greenhouse operating cost greatly.This sunshading and thermal insulating system can also stop indoor steam unrestrictedly to escape, and effectively keeps air humidity, reduces irrigation water, prolongs the crop harvesting phase, and reaching increases crop yield, raising crop quality effect.

Among the figure: 1, truss; 2, driving mechanism; 3, analog bracket; 4, shade supporting wire; 5, driving shaft; 6, draw curtain rack-and-pinion; 7, pull bar; 8, aluminium alloy drives the limit; 9, internal sunshade curtain; 10, insulation curtain; 11, column.

Embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

See also Fig. 1, greenhouse internal sunshade heat-insulation system, comprise column 11, truss 1, driving mechanism 2, pull bar 7, draw curtain rack-and-pinion 6 and curtain, the column upper end is equipped with three layers of truss, install driving mechanism 2 and the driving shaft 5 parallel on every layer of truss with truss, and the pull bar vertical with truss 7 is installed by analog bracket 3, axle shaft gear is housed on driving shaft, axle shaft gear is meshed with the gear of draw curtain rack-and-pinion 6 on being packed in truss, is fixed with curtain by shade supporting wire 4 on each pull bar 7.Be fixed with greenhouse internal sunshade curtain 9 by shade supporting wire on the described upper and lower pull bar, be fixed with greenhouse heat-insulating curtain 10 on the middle pull bar, greenhouse internal sunshade curtain 9 is to be made of through the high strength PE yarn braiding the wide polyester plastics bar of 4m, and described insulation curtain 10 adopts aluminium foil to form with the braiding of high-strength polyester yarn.Greenhouse internal sunshade curtain and insulation curtain all are connected with aluminium alloy and drive limit 8, and this aluminium alloy drives the position that will arrive that limit 8 is used for controlling internal sunshade curtain and insulation curtain.

Operation principle of the present utility model is:

Start driving mechanism, make it drive driving shaft and axle shaft gear rotates, at this moment the draw curtain rack-and-pinion gear with the axle shaft gear engagement rotates, and drives pull bar and move horizontally, and draws back ante-venna then.

Summer, utilize the internal sunshade curtain to keep the sun off, stop unnecessary solar radiation to enter the greenhouse, guarantee that promptly crop can normal growth, reduce indoor energy accumulating again, cover crop avoids high light burns, and makes indoor temperature 4-7 degree that descend; In winter, the insulation curtain has the effect that prevents that indoor infrared rays from escaping, and reduces heat-energy losses, thereby improves temperature in the greenhouse, cuts down the consumption of energy, and reduces the winter operation cost.Use curtain in the weaving of insulation curtain aluminium, and adopt the motor special that has Stroke Control, can realize each unit independent startup.
