High-performance double sunlight greenhouse for four seasons

Abstract

The invention discloses a high-performance double sunlight greenhouse for four seasons, which is fixedly arranged on a ground plane and a wall, and consists of an inner-layer shed frame and an outer-layer shed frame, wherein the inner-layer shed frame is coated with an inner-layer shed film; an inner-layer insulting quilt covers the inner-layer shed film; the outer-layer shed frame is coated with an outer-layer shed film; an outer-layer insulating quilt covers the outer-layer shed film; and an air thermal insulating layer is formed between the inner-layer shed frame and the outer-layer shed frame. The inner-layer insulating quilt is wound on an inner-layer rolling blinds machine; the inner-layer shed film is wound on an inner-layer film rolling machine; an outer-layer insulating quilt is wound on an outer-layer rolling blinds machine; the wall on the aground part is a hollow wall, and the hollow part is filled with an insulating layer; internal and external walls are respectively built on two sides of the hollow part of the wall; a row of handle bricks are built between the internal wall and the external wall where the shed frames are arranged; the distance between the handle bricks is the same as that between the shed frames of the greenhouse; and the handle bricks connect the internal and external walls together. The high-performance double sunlight greenhouse has the advantages of good thermal insulation property, safety of operation, application in four seasons, and long service life.

Description

Technical field: [0001] The invention belongs to a modern agricultural production facility, in particular to a four-season high-performance double-mounted solar greenhouse used for planting vegetables at low temperature. Background technique: [0002] The solar greenhouse is an agricultural production facility that is suitable for my country's national conditions and has independent intellectual property rights. It alleviates the contradiction between supply and demand of vegetables in the off-season, and also becomes an important way for Chinese farmers to get rich. As early as the 1970s, simple solar greenhouses were built in my country. From the late 1980s to the early 1990s, various energy-saving solar greenhouses with their own characteristics were successively researched and developed (collectively referred to as "second-generation energy-saving greenhouses"). In 2006, our unit invented the "high-efficiency and energy-saving internal heat preservation solar greenhouse"...

AI Technical Summary

Problems solved by technology

[0004] ⑥The second-generation energy-saving greenhouse generally only has two layers of insulation quilt and shed film for insulation. The lowest temperature in the greenhouse in winter is only 4-6°C, and sometimes it can’t reach 4°C. The basic requirements for the normal growth of temperature-loving vegetables cannot be guaranteed, so the greenhouse can be cultivated The range of vegetable types is very narrow, and the safety of vegetable production cannot be guaranteed

[0005] ⑦The thermal insulation quilt of the second-generation energy-saving greenhouse is directly exposed on the surface of the greenhouse. When it snows in winter, all the snow accumulates on the thermal insulation quilt. also increased security risks

[0006] ⑧ The second-generation energy-saving greenhouse can not solve the problem when vegetables need to be kept warm and shaded in summer

[0007] ⑨Although the high-efficiency and energy-saving inner thermal insulation solar greenhouse realizes the built-in thermal insulation quilt, which greatly improves the thermal insulation performance compared with the second-generation energy-saving solar greenhouse, but because there is no outer thermal insulation protection, the inner wall of the outer shed film freezes at night in cold seasons, and it is necessary to The inner shed film cannot be rolled up until the ice is completely melted, and the plants in the shed will receive sunlight about 0.5 hours later than the second-generation energy-saving greenhouse
