Composite-structure sunlight greenhouse wall body

Abstract

The invention discloses a composite-structure sunlight greenhouse wall body. The composite-structure sunlight greenhouse wall body comprises an inner wall body, a ring beam, an outer wall body, a heat-insulating layer, a ground and an air layer, wherein the inner wall body is provided with a ventilation fan; the heat-insulating layer is mounted on the outer side of the outer wall body. The composite-structure sunlight greenhouse wall body has a simple structure, a strong heat accumulation capability, good wall body stability, long service and low cost and has tangible practicability on the aspects of solving the supply problem of fresh vegetables in winter in the northern region and increasing the economic incomes of farmers.

Description

technical field [0001] The invention belongs to the field of greenhouses, and in particular relates to a solar greenhouse wall with a composite structure. Background technique [0002] The solar greenhouse is a kind of greenhouse structure with Chinese characteristics and is a unique facility in our country, which is jointly created by the majority of agricultural science and technology workers and farmers. It can produce without heating in winter, solve the supply problem of fresh vegetables in winter in northern regions, and increase the economic income of farmers. In current agricultural production, the protection facilities with the largest area are solar greenhouses and large sheds. Solar greenhouses have the best protection conditions and can carry out agricultural production throughout the year. Therefore, in most parts of northern my country, solar greenhouses are the main way to cultivate vegetables in winter , but at the same time, due to technical defects and exce...

[0004] Chinese patent CN103362226A discloses a thermal insulation wall of a vegetable greenhouse, which includes an outer wall, a thermal insulation layer, an inner wall and a roof, wherein the thermal insulation layer is arranged between the outer wall and the inner wall, although it plays a role in the heat preservation and heat storage of the greenhouse. To a certain extent, but the insulation layer is not conducive to replacement, shortening the service life of the wall, in addition, the entire inner wall is provided with a number of breathing holes through the inner wall, which cannot effectively store heat in the greenhouse, and is not conducive to the wall body stability
