Light-transmitting and heat retaining planting greenhouse

Abstract

The invention provides a light-transmitting and heat retaining planting greenhouse integrating light transmittance and heat preservation. The planting greenhouse comprises frame beams, inside and outside light transmitting film fixed to the top surfaces and bottom surfaces of the frame beams through elastic casting pieces, and each frame beam comprises an upper beam member, a lower beam member andconnecting pieces used for connecting the upper and lower beam members; each upper beam member is a strip groove with a groove mouth facing upward and a cross section in a shape like an inverted Chinese character of 'tu', each lower beam member is the strip groove symmetrical to each upper beam member structure, and the connecting pieces comprise left connecting pieces and right connecting pieceswhich are located at the left and right sides of the upper and lower beam members and have same lengths with the upper and lower beam members; the top ends of the left and right connecting pieces arefixed to two invaginated horizontal planes of the lower portion of each upper beam member, and the lower ends of the left and right connecting pieces are fixed to two invaginated horizontal planes ofthe upper portion of each lower beam member. According to the light-transmitting and heat retaining planting greenhouse, the structure is simple, the greenhouse has light weight and good bearing capacity, sunlight can be directly emitted into the greenhouse through the inside and outside light transmitting film in the daytime, the inside and outside light transmitting film can achieve better thermal insulation and heat preservation effects on a cold or rainy night.

Description

technical field [0001] The invention relates to a heat preservation device, in particular to a device suitable for planting in greenhouses for crops and integrating light transmission and heat preservation, and more particularly to a light transmission and heat preservation planting greenhouse integrating light transmission and heat preservation. Background technique [0002] With the continuous advancement of science and technology, the use of plastic film greenhouse planting technology in agricultural planting is more and more accepted by people, but in the cold north, the insulation work of greenhouses is a difficult point in greenhouse planting. An important part of efficiency. Existing plastic film greenhouses generally include a greenhouse frame and a plastic plate or film laid on the frame of the greenhouse. Most of the frame of the greenhouse is made of round or flat steel. Larger, which makes the integrated house heavy and costly, and the plastic sheet or film is l...

Problems solved by technology

Existing plastic film greenhouses generally include a greenhouse frame and a plastic plate or film laid on the frame of the greenhouse. Most of the frame of the greenhouse is made of round or flat steel. Larger, which makes the integrated house heavy and costly, and the plastic sheet or film is laid on this kind of frame, and it is necessary to add a lamination line on the plastic sheet or film to fix it with the frame; and in order to make the greenhouse The plants can survive and grow safely in the low temperature at night or the cold weather in winter. The traditional heat preservation method is to cover the roof of the greenhouse with thermal insulation curtains. The thermal insulation curtains are usually straw curtains or waste quilts made by farmers themselves. When it is sufficient, roll up the thermal insulation curtain, and at night, on cloudy or rainy days, put down the thermal insulation curtain and spread it out; Laying the curtains is labor-intensive, especially in rainy or snowy weather, the humidity and snow can easily crush the greenhouse
