Abstract
The invention discloses a rain draining groove of a composite span greenhouse with good photopermeability and heat retaining property. The rain draining groove comprises a 'U'-shaped sectional material beam frame, a rain draining groove and a fixed film clamping groove, wherein the bottom of the 'U'-shaped sectional material beam frame is connected with and is supported by a plurality of greenhouse support columns, a plurality of greenhouse arch bars are connected with two sides of the 'U'-shaped sectional material beam frame in a supporting way, the top of the 'U'-shaped sectional material beam frame is flatly provided with the rain draining groove, and two sides of the rain draining groove are fixed with the greenhouse arch bars by the fixed film clamping groove. Compared with the conventional rain draining groove which is folded by a metal thin plate, the structural strength and the structural rigidity of the greenhouse are simultaneously improved, the separation distance and the span of the greenhouse are expanded, the number of greenhouse support columns is reduced, the photopermeability and the heat retaining property of the greenhouse are improved, the land use capability of the greenhouse is improved, and the operability of the mechanized production of the greenhouse is improved. The contrast test shows that the sunshade area is reduced by more than 2/3, the daylighting rate is improved by 70%, and the heat retaining property is improved by more than 84%.
Description
Technical field
The present invention relates to heliogreenhouse facility field, specifically a kind of plyability attached-greenhouse row rain groove of light-permeable good heat preservation performance.
Background technology
The industrialized agriculture industry is one of agricultural modernization level important symbol, and swift and violent in China's development in recent years, the area of China's facilities horticulture ranks first in the world.But to stride forward to facilities horticulture power, must break through tripartite surface technology bottlenecks such as horticultural facility type, regulation and control environment, cultivation technique.In order to improve the efficient of horticultural facility, the general attached-greenhouses that adopt more.
The structure of existing attached-greenhouse generally adopts steel work, for guaranteeing that rainwater does not flow in the greenhouse when the rainfall snowfall, existing attached-greenhouse and between the row's of being provided with rain groove, row's rain groove is except the function of the row's of bearing rainwater, snow-broth, also, play the beam effect that connects arch bar and greenhouse pillar as the bearing of greenhouse arch bar.
In the prior art, row's rain groove is generally made with metal sheet roof covering, has the following disadvantages: 1) for strengthening the intensity and the rigidity of greenhouse structure, must correspondingly increase the sectional dimension of row's rain groove, make the also corresponding increase of sunshade rate; 2) the coefficient of thermal conductivity height of metal row rain groove, thickness is little, and heat scatters and disappears big; 3) metal row rain groove is subjected to the influence of dead weight, and the greenhouse pillar has been produced extra burden, is rigidity and the stability that guarantees whole greenhouse, has only the greenhouse of sacrifice spacing, increase pillar, the daylighting rate that this has influenced the greenhouse to a certain extent again also is unfavorable for the greenhouse mechanized; 4) metal row rain groove need carry out zinc-plated processing, could resist oxidation and water erosion; 5) thermal deformation of metal row rain groove is big, and row's rain groove is yielding, split and leak, and connects the slit though can lean on the rubber-like material to fill up, and owing to too big with steel material difference, can't accomplish real seamless link, is easy to generate dew, influences hothouse production; 6) row's rain groove of metal sheet roof covering structure needs special large-sized sheet material extrusion apparatus, and manufacture difficulty is big, cost is high.
Summary of the invention
The objective of the invention is to overcome the defective that prior art exists, a kind of plyability attached-greenhouse row rain groove of light-permeable good heat preservation performance is provided.
Technical scheme of the present invention is as follows:
The plyability attached-greenhouse row rain groove of light-permeable good heat preservation performance of the present invention comprises " U " type section bar roof beam structure, row's rain groove and solid film draw-in groove, the bottom of " U " type section bar roof beam structure is connected with the greenhouse pillar and by the greenhouse shore supports, greenhouse arch bar support and connection are in the both sides of " U " type section bar roof beam structure, top horizontal at " U " type section bar roof beam structure has row's rain groove, and the both sides of row's rain groove are fixed with solid film draw-in groove and greenhouse arch bar.
Described " U " type section bar roof beam structure is made with metal material, and length is 4m-8m.
Described row's rain groove is made with the light transmission nonmetallic composite, and length is 4m-8m.
Described solid film draw-in groove also can be used for fixedly greenhouse plastic foil in fixing row's rain groove and greenhouse arch bar.
The plyability attached-greenhouse row rain groove of light-permeable good heat preservation performance of the present invention is compared with row's rain groove that conventional metals thin plate crimping is shaped, and has following beneficial effect:
(1) when improving greenhouse structure intensity and rigidity, expanded the spacing and the span in greenhouse, reduced the pillar in greenhouse, improved the light transmittance and the heat-insulating property in greenhouse, improved the land utilization ratio in greenhouse, improved the operability that greenhouse mechanization is produced.Contrast test shows that the sunshade area has reduced more than 2/3, and the daylighting rate has improved 70%, and heat-insulating property improves more than 84%.
(2) with the bonding connection of composite material bulk material, simple installation can not leak.
(3) prolonged row's rain groove life, reduced the pillar in greenhouse, the construction cost of having saved the greenhouse has reduced the cost in greenhouse.
(4) process equipment is simple, manufacturing is simple and easy, simple installation.
