Description
Technical Field
The utility model belongs to the technical field of the big-arch shelter greenhouse, specifically speaking relates to a plastic film 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.
The common method of the existing greenhouse roof is that the window opening area is only 20-30% of the total surface area of the dome roof of the greenhouse, the problem is improved, but the area of the dome roof window is small, the top area is closed, the temperature cannot be completely discharged at the highest position of the whole roof, and the heat energy can be released only from the window opening of the side wall, so that the maximum ventilation volume of the greenhouse is seriously influenced, and the adjusting effect of the whole greenhouse is not obvious. The windows are arranged on the two sides of the top area, when external wind enters the greenhouse through the window arranged on one side, upward lifting is easily formed in the closed area of the greenhouse top, when the wind quantity is large, the whole greenhouse top is easily lifted from the closed area to turn over the greenhouse, and therefore the wind resistance performance of the greenhouse is extremely low.
Therefore, the existing greenhouse has more problems to be solved, and needs to be structurally adjusted. The utility model discloses what the main improvement was a top membrane structure for greenhouse shed roof.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a top film structure for the greenhouse roof aiming at the defects, and the problems of the maximum ventilation quantity and the fastest temperature adjustment of the greenhouse are solved; the problem of big-arch shelter wind-resistant performance not good is solved. In order to achieve the above object, the utility model provides a following technical scheme:
a top film structure for greenhouse shed top comprises a plurality of supporting top frames and a top film 6; the vault of the supporting top frame protrudes outwards, a top film 6 is arranged at the vault of the supporting top frame, and the top film 6 can be rolled to the vault of the supporting top frame; and/or the top film 6 can be covered from the vault of the supporting top frame to two sides; the side surface of the supporting top frame is provided with a window which extends for a certain distance from the vault along the two sides of the supporting top frame; the top film 6 may completely cover the window. According to the structure, the side face of the supporting top frame is provided with the window which extends for a certain distance from the vault along the two sides of the supporting top frame, and the window can be closed by covering the top film to preserve heat or opened by taking off the top film to ventilate; the top film 6 can be rolled to the vault of the supporting top frame, the top of the greenhouse can be completely opened, the whole window is opened at the highest end of the greenhouse, the windows on the two sides of the supporting top frame are completely opened, convection current can be effectively formed, accordingly, the purposes of maximum ventilation and fastest temperature adjustment are achieved, and because the humidity is accompanied by the temperature at the highest point of the greenhouse (the transpiration effect of hot air going upwards), the humidity in the greenhouse is adjusted fastest, the humidity is reduced, plant diseases and insect pests are reduced, and therefore the greenhouse with the best effect of adjusting the plant diseases and insect pests in the multi-span greenhouse is also provided. The window is arranged at the highest end of the greenhouse, so that pressure on the top is avoided when strong wind enters the greenhouse. The vault of the supporting top frame is outwards convex, so that the top film can be rolled to the vault, and the whole top film can be effectively prevented from being lifted by wind; the greenhouse with the large-area movable film can be normally used (within 8-grade wind power).
Further, the window occupies the area of the side 2/3 ± 1/10 of the supporting top frame. With the structure, when temperature adjustment is needed, the top film of the window area of the dome of the greenhouse can be opened almost completely, so that the top film 2/3 of the greenhouse can be opened completely; and the window is arranged at the highest end of the greenhouse, so that the purposes of the maximum ventilation quantity and the fastest temperature adjustment are achieved, and because the humidity is accompanied with the temperature at the highest point of the greenhouse (the transpiration effect of hot air moving upwards), the humidity in the greenhouse is adjusted fastest, and the pest and disease damage can be reduced by reducing the humidity, so that the greenhouse is also the greenhouse with the best pest and disease damage adjusting effect in the multi-span greenhouse.
Furthermore, the supporting top frame comprises two top frames with arc structures, and the two top frames are intersected at the arch top to enable the arch top to be convex/pointed, so that the whole supporting top frame is in a peach-shaped structure.
