Description
Technical Field
The invention relates to a heat preservation device, in particular to a device which is suitable for planting in a crop greenhouse and integrates light transmission and heat preservation, and more particularly relates to a light transmission and heat preservation planting greenhouse which integrates light transmission and heat preservation.
Background
With the continuous progress of scientific technology, the technology of planting plastic film greenhouses is more and more accepted in the aspect of agricultural planting, but in cold north, the heat preservation work of the greenhouses is a difficult point in greenhouse planting and is an important link for obtaining high benefit. The existing plastic film greenhouse generally comprises a greenhouse framework and plastic plates or films paved on the greenhouse framework, wherein the greenhouse framework is mostly made of round or flat steel materials, and the steel materials have good bearing capacity, but the weight of an integrated house is large due to the fact that the specific gravity of solid steel materials is large, the cost is high, and plastic plates or films are paved on the framework and a film pressing line is additionally arranged on the plastic plates or films to be fixed with the framework; in order to ensure that plants in the greenhouse can be transferred and grown in cold weather at night or in winter, the traditional heat preservation method is to cover a heat preservation curtain on the top of the greenhouse, wherein the heat preservation curtain is usually a grass curtain or a waste cotton quilt woven by peasants, and the heat preservation curtain is rolled up when sunlight is sufficient in daytime, and is laid down and covered in evening, cloudy days or rainy days; because the heat-insulating curtain has the defects of heavy weight, poor heat-insulating performance and short service life, the labor intensity of rolling and putting the curtain is high, and the greenhouse is easy to be destroyed due to moisture and snow in rainy or snowy days.

The connecting piece is a corrugated plate with a plurality of equidistant trapezoid peaks and valleys on the surface, the direction of the alternating arrangement of the corrugated plate peaks and valleys is the same as the length direction of the upper beam member and the lower beam member, and the distance from the corrugated plate peaks to the valleys is equal to the width of the concave part at the bottom of the upper beam member.
The connecting piece is an S-shaped steel bar, the length direction of the S-shaped steel bar is the same as the length direction of the upper beam member and the lower beam member, and the diameter of the S-shaped steel bar is equal to the width of the concave part at the bottom of the upper beam member.
In order to enable the side wall of the planting greenhouse to have a good light-transmitting and heat-preserving effect, the upright post also has the same structure as the frame beam, and the inner light-transmitting film and the outer light-transmitting film are fixed on the two sides of the upright post through the elastic pressing piece.
The section of the elastic pressing piece is rivet-shaped and comprises a top cover and a vertical pressing bar, and a boss is outwards formed at the lower part of the vertical pressing bar.
In order to increase the tightness degree of the combination of the notch of the upper beam member and the elastic pressing strip, two sides of the notch of the upper beam member and two sides of the notch of the lower beam member are downwards bent to form a flange, and the flange just abuts against a boss at the lower part of the vertical pressing strip of the elastic pressing piece.
In order to facilitate the manufacture, the connecting piece is fixed with the upper beam member and the lower beam member by welding.
In order to reduce the chance of rusting of the frame beam, the upper beam component and the lower beam component are processed by galvanized plates.
The light-transmitting thermal-insulation planting greenhouse has the advantages that the frame beams are long-strip-shaped groove bodies with the cross sections being in a convex shape and symmetrical in structure, the long-strip-shaped groove bodies are used as upper and lower beam members, the left and right connecting pieces are connected into a whole, the left and right connecting pieces are of hollow structures, the self weight of the whole frame beam is very light, the connecting pieces and fixed points of the upper and lower beam members are connected into curves due to the fact that the side walls of the upper and lower beam members are in the step shape, the stress on the top surfaces and the side surfaces of the frame beams can be well decomposed, the top ends of the connecting pieces just abut against the concave parts of the lower parts of the upper beam members, and the lower ends of the connecting pieces just abut against the concave parts of the upper parts of the lower beam members, so that the whole frame beam has good bearing capacity; in addition, because the upper beam member and the lower beam member are of strip groove structures with upward or downward openings, the inner and outer light-transmitting films can be clamped into the upper beam member and the lower beam member through the elastic pressing piece to be fixed on the frame beam, the mode of fixing the plastic film through the film pressing line is thoroughly replaced, and a sealed air layer is formed between the inner and outer light-transmitting films, so that heat energy loss caused by heat conduction inside and outside the greenhouse can be greatly reduced. The light-transmitting heat-preserving greenhouse has the advantages of simple structure, light dead weight and good bearing capacity, sunlight can directly enter the greenhouse through the inner light-transmitting film and the outer light-transmitting film in daytime, so that the greenhouse is heated and plants are subjected to photosynthesis, the inner light-transmitting film and the outer light-transmitting film can play a good role in heat insulation and heat preservation in evening at low temperature or in overcast and rainy days, and the light-transmitting heat-preserving greenhouse is particularly suitable for greenhouse planting in areas with large day and night temperature difference.
