Description
Technical Field
The utility model belongs to the technical field of the big-arch shelter greenhouse, specifically speaking relates to a water conservancy diversion structure for greenhouse shed roof.
Background
The greenhouse technology is widely applied to planting/cultivation of modern agriculture such as flowers, fruits and vegetables, and gradually becomes important agricultural production equipment. In the specific application process of the greenhouse technology, factors including temperature, humidity, carbon dioxide, oxygen, illumination, rain sheltering, frost prevention, snow prevention, plant diseases and insect pests and the like are important adjusting conditions of the greenhouse, like the brain of the greenhouse, so that the adjusted small environment of the greenhouse is most suitable for plant growth, and the aim of high-efficiency modern agriculture is achieved.
Present greenhouse canopy plays heat retaining effect winter, but in the confined big-arch shelter, humidity is along with the top gathering of temperature to greenhouse, because the existence of inside and outside difference in temperature, be formed with the comdenstion water at the shed roof, the comdenstion water gathering can drip downwards after the certain degree, perhaps can be in the same direction as the flow to both sides of shed roof, when the comdenstion water flows down to the draw-in groove department of shed roof, the growth of serious influence plant in the canopy can be dripped to the water, a large amount of germs of cold water in the greenhouse, drip and can cause the plant disease to propagate on the plant, the plant rots, make the comdenstion water can't be discharged at the shed roof.
Therefore, the existing greenhouse has more problems to be solved, and needs to be structurally adjusted. The utility model discloses what the main improvement is a water conservancy diversion structure for greenhouse shed roof.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the above-mentioned weak point provide a water conservancy diversion structure for greenhouse shed roof, the unable discharge of condensate in the greenhouse is solved to the intention, drips and can cause the problem that the disease spreads, the plant is rotten to the plant in the greenhouse. In order to achieve the above object, the utility model provides a following technical scheme:
a diversion structure for greenhouse shed roof comprises a plurality of supporting roof frames, a skirt film 4 and a roof film 6; the arch top of the supporting top frame is outwards convex; the skirt membrane 4 is arranged on the surface of the lower part of the supporting top frame, and the top edge of the skirt membrane 4 is inwards sunken at the position of the supporting top frame to form a flow guide port; the top film 6 is arranged on the surface of the upper part of the supporting top frame, and the bottom edge of the top film 6 can exceed the top edge of the skirt film 4, so that a mutual fit overlapping area is formed between the top film 6 and the skirt film 4; in the overlap region, the top membrane 6 is on the outside and the skirt membrane 4 is on the inside.
