Abstract
The utility model discloses a light-transmissible gutter for a multi-span greenhouse. The light-transmissible gutter is formed by a sectional material beam frame shaped like a Chinese character xi, a gutter and film-fixing clamping grooves. The bottom of the sectional material beam frame shaped like the Chinese character xi is connected with a greenhouse strut and supported through the greenhouse strut, two sides of the sectional material beam frame shaped like the Chinese character xi are connected with and support greenhouse arch bars, the gutter is horizontally arranged at the top of the sectional material beam frame shaped like the Chinese character xi, and two sides of the gutter are fixed with the greenhouse arch bars through the film-fixing clamping grooves. The gutter is compositely made of epoxy resin serving as a base material and auxiliary materials such as addition agents and transparent fibers by multiple processes such as molding, and is light-transmissible, moisture-resistant, corrosion-resistant and small in temperature change coefficient. The film-fixing clamping grooves further have the effects of fixing a greenhouse plastic film. Compared with a traditional gutter formed by folding sheet metal, the light-transmissible gutter reduces sunshade area by over 2/3, improves lighting rate by 70% and improves heat insulation performance by over 84%. The land use rate of the greenhouse and operability in mechanized production are improved, the service life of the gutter is prolonged, the greenhouse building cost is reduced, and the fabrication cost of the greenhouse is reduced.
Description
Technical field
The utility model relates to greenhouse by solar heat facility field, specifically a kind of gutter of plyability attached-greenhouse 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 the three aspects: technical bottlenecks such as horticultural facility type, regulation and control environment, culture technique.In order to improve the efficient of horticultural facility, the general attached-greenhouses that adopt more.And the structure of existing attached-greenhouse generally adopts steel construction, for guaranteeing that rainwater does not flow in the greenhouse when the rainfall snowfall, existing attached-greenhouse and between be provided with gutter, gutter is except the row's of bearing rainwater, snow-broth function, also as the bearing of greenhouse arch bar, work the beam effect that connects arch bar and greenhouse pillar.Gutter is generally made with the sheet metal steel plate in the prior art, therefore has some problems: for strengthening the strength and stiffness of greenhouse structure, must correspondingly increase the sectional dimension of gutter, the also corresponding increase of sunshade rate; The metal gutter thermal conductivity factor is high, and thickness is little, and heat loss is large; The impact of metal gutter dead weight has produced extra burden to the greenhouse pillar, is rigidity and the stability that guarantees whole greenhouse, only has the greenhouse of sacrifice spacing, increase pillar, the daylight rate that this has affected again the greenhouse to a certain extent also is unfavorable for the greenhouse do mechanization operation; Metal gutter need to carry out zinc-plated processing to gutter, could resist oxidation and water erosion; The metal gutter thermal deformation is large, and gutter is yielding, split and leak, and connects the slit although fill up by the rubber-like material, owing to can't accomplish real seamless link too greatly with the material difference of steel, generation is leaked or dewfall affects hothouse production easily; The gutter of metal thin plate structure needs special large-sized sheet material extrusion apparatus, and manufacture difficulty is large, cost is high.
Summary of the invention
The defective that exists for overcoming prior art, the utility model provides a kind of light-transmissive gutter of attached-greenhouse, and the greenhouse is reduced more than 2/3 by the sunshade area that gutter forms, and daylight rate improves more than 70%, and heat-insulating property improves 80%.
For achieving the above object, the technical solution adopted in the utility model is as follows:
The light-transmissive gutter of attached-greenhouse of the present utility model is made of " ㄈ " type section bar roof beam structure, gutter and solid film draw-in groove, the bottom of " ㄈ " type section bar roof beam structure is connected with the greenhouse pillar and by the greenhouse shore supports, the both sides connection of " ㄈ " type section bar roof beam structure is also being supported greenhouse arch bar, the top horizontal of " ㄈ " type section bar roof beam structure gutter, and the dual-side of gutter is fixed with solid film draw-in groove and greenhouse arch bar.
Described gutter is take epoxy resin with transparent characteristic as base-material, multiple tracks technique is compound makes through molded etc. to be aided with the materials such as auxiliary agent and vitreous fibre, it is little to have light transmission, humidity, not corrosion, warm variable coefficient, but the composite product that strength and stiffness is less, the length available of its minimum sunshade rate are 4m-8m.
The dual-side setting in the ditch of following the mandate of heaven of described solid film draw-in groove is in fixedly gutter and greenhouse arch bar, also for fixing greenhouse plastic foil.
The light-transmissive gutter of attached-greenhouse of the present utility model is compared with the gutter that traditional metal thin plate crimping is shaped has following beneficial effect:
(1) when improving the greenhouse structure strength and stiffness, expand spacing and the span in greenhouse, reduced the pillar in greenhouse, improved light transmittance and the heat-insulating property in greenhouse, improve the land utilization rate in greenhouse, improved the operability of greenhouse mechanization production.Comparative trial shows that sunshade area has reduced more than 2/3, and daylight rate has improved 70%, and heat-insulating property improves more than 84%.
(2) with the bonding connection of composite bulk material, simple installation can not leak.
(3) prolong the gutter life-span, reduced the pillar in greenhouse, saved the construction cost in greenhouse, reduced the cost in greenhouse.
(4) process equipment is simple, manufacturing is simple and easy, simple installation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is cross section structure schematic diagram of the present utility model.
Among the figure: 1, " ㄈ " type section bar roof beam structure, 2, gutter, 3, solid film draw-in groove, 4, the greenhouse pillar, 5, greenhouse arch bar, 6, plastic foil.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, the light-transmissive gutter of attached-greenhouse of the present utility model is made of " ㄈ " type section bar roof beam structure 1, gutter 2 and solid film draw-in groove 3.The bottom of " ㄈ " type section bar roof beam structure 1 is supported by greenhouse pillar 4, the both sides connection of " ㄈ " type section bar roof beam structure 2 is also being supported greenhouse arch bar 4, the top horizontal of " ㄈ " type section bar roof beam structure 1 gutter 2, and the dual-side of gutter 2 is fixing with greenhouse arch bar 5 with solid film draw-in groove 3." ㄈ " type section bar roof beam structure 2 is made for metal material, and length is 4m-8m.Gutter 2 is take epoxy resin as base-material, multiple tracks technique is compound makes through molded etc. to be aided with the materials such as auxiliary agent and vitreous fibre, it is little to have light transmission, humidity, not corrosion, warm variable coefficient, but the less composite product of strength and stiffness, the length available of its minimum sunshade rate is 4m-8m.The dual-side setting in the ditch Gu film draw-in groove 3 is followed the mandate of heaven is in fixing gutter 2 and greenhouse arch bar 5, also for fixing greenhouse plastic foil 6.
