The two-sided canopy film of bow member heliogreenhouse
Technical field
The utility model belongs to the greenhouse, particularly relates to the two-sided canopy film of a kind of bow member heliogreenhouse.
Background technology
At present, the occupancy volume of chamber planting in agricultural planting is increasing, and particularly the winter planting vegetables had both solved vegetables and supplied with problem, can give peasant's extra earning again.But existing greenhouse all needs it is heated in the winter time, to guarantee the needs of vegetable growth.The deficiency of its existence is: heating temperature is low, consume fuel is many, and temperature fluctuation is big, cigarette, grey seriously polluted to the greenhouse; Adopt steam or hot water space heating boiler to heat to the greenhouse in addition by radiator, but its cost height, equipment complexity, cost height.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and the two-sided canopy film of a kind of bow member heliogreenhouse is provided.
The two-sided canopy film of bow member of the present utility model heliogreenhouse, be to be configured to by curtain by back wall, bow member, outer canopy film and ridge, back wall is that seat is erect on the wall base of back and is connected to the shed adverse grade, and back wall and shed adverse grade are to fill insulation material between double-deck clamping plate, interlayer.The top of bow member is supported on the body of wall, and prolong shed adverse grade inboard to ridge place turn back downward-sloping extension be connected to before on the wall base.Canopy film in canopy film, the inboard attaching outside the outer side covers of bow member.
As further improvement of the utility model, the inboard of back wall is pasted with reflector.
As further improvement of the utility model, the preceding domatic horizontal sextant angle of described bow member is 40~51 °.
As further improvement of the utility model, the heat insulating material of filling in the interlayer of back wall and shed adverse grade is fluffy material any and composition thereof of foamed plastic, cereal shell, perlite, crushing straw or herbage.
As further improvement of the utility model, the thickness of outer canopy film is that 0.6~1.0 millimeter, the thickness of interior canopy film are 0.3~0.5 millimeter, and its light transmittance is greater than 85%.
As further improvement of the utility model, all be pasted with insulation benzene plate in the outside of the back wall base and the preceding wall base.
The two-sided canopy film of the utility model bow member heliogreenhouse, reasonable in design has been broken the plantation in winter of traditional booth and must have been heated to improve the method for room temperature with straw or fire coal.It is extremely efficient in preserving heat, and daylighting is good, and the daylighting of canopy film own just can make interior temperature reach the needs of crop production, not only invests lowly, but also has guaranteed the cleaning in the greenhouse, more utilizes the production of crop, and this greenhouse can be widely used in plant husbandry and aquaculture.

Figure of description is the structural representation of the two-sided canopy film of the utility model bow member heliogreenhouse.
The specific embodiment
Embodiment 1
The two-sided canopy film of bow member of the present utility model heliogreenhouse, be to be constituted by curtain frame 4 by back wall 1, bow member 2, outer canopy film 3 and ridge, back wall 1 is that seat setting on the wall base 5 of back is connected to shed adverse grade 6, and back wall 1 and shed adverse grade 6 are filling-foam plastics or cereal shells between double-deck clamping plate, interlayer, be pasted with reflector 9 in the inboard of back wall 1, to replenish indoor intensity of illumination, playing increases heat and insulation effect.The top of bow member 2 is supported on the body of wall 1, and prolong shed adverse grade 6 inboards to ridge place turn back downward-sloping extension be connected to before on the wall base 7, the preceding domatic horizontal sextant angle of bow member 2 is 40~51 °.Canopy film 8 in canopy film 3, the inboard attaching outside the outer side covers of bow member 2.
Embodiment 2
The two-sided canopy film of bow member of the present utility model heliogreenhouse, be to be constituted by curtain frame 4 by back wall 1, bow member 2, outer canopy film 3 and ridge, back wall 1 is that seat setting on the wall base 5 of back is connected to shed adverse grade 6, and back wall 1 and shed adverse grade 6 are the mixtures of filling perlite and crushing straw between double-deck clamping plate, interlayer, be pasted with reflector 9 in the inboard of back wall 1, to replenish indoor intensity of illumination, playing increases heat and insulation effect.The top of bow member 2 is supported on the body of wall 1, and prolong shed adverse grade 6 inboards to ridge place turn back downward-sloping extension be connected to before on the wall base 7, the preceding domatic horizontal sextant angle of bow member 2 is 40~51 °.Canopy film 8 in canopy film 3, the inboard attaching outside the outer side covers of bow member 2, its light transmittance is greater than 85%.Wherein, the outside of the back wall base 5 and the preceding wall base 7 all is pasted with insulation benzene plate.
The basic principle of daylight duplicature moist closet design is " transparent heat insulating ", is based on printing opacity.Under same solar irradiation condition, as long as bow member covers PO canopy film, solar energy just can be injected heliogreenhouse in effective time.PO film light transmittance height, the speed that heats is fast, so the outer canopy film quality of heliogreenhouse directly has influence on the temperature in greenhouse.
The interior canopy film of daylight duplicature moist closet adopts PO film 0.4mm to subtract the full Electrostatic Treatment of mist throughout one's life, and its light transmittance is not less than 85%, outer canopy film 0.75mm.Interior adventitia is thickness 11.5mm altogether, so neither influences printing opacity, and room temperature is blocked, and in indoor slow heat conduction, guarantees crop normal growth at night, though outside temperature-37 the degree low temperature the time, interior temperature also be not less than above freezing 7 the degree.
