A new solar greenhouse back wall structure

Abstract

The invention relates to a novel solar greenhouse backwall structure which comprises a fixed wall body, a dismounting wall body and a wall body supporting structure. The fixed wall body is built by laying hollow blocks, and a thermal storage layer, a thermal-protective layer and an insulating layer are distinct in dividing line. The dismounting wall body is built on the fixed wall body through straw blocks, performs a heat insulation and heat preservation function when a solar greenhouse carries out production in winter, and is dismounted to enlarge draught areas and perform cooling effects when the solar greenhouse carries out production in seasons with higher temperature. The cage type supporting structure is formed by stand columns, tie bars, transverse beams and longitudinal beams, and load born by the framework of the solar greenhouse is transmitted to the ground directly. Through the mounting and dismounting of the rear wall, the solar greenhouse with the backwall structure can achieve heat insulation and aeration cooling respectively, can carry out normal production and operation at all seasons, and the indoor land use rate and economic benefit are improved.

Description

technical field [0001] The invention relates to a solar greenhouse wall body, in particular to a novel solar greenhouse rear wall structure. Background technique [0002] The solar greenhouse utilizes the principle of its back wall to store heat during the day and release heat at night, to give full play to its advantages in thermal insulation performance in the "Three North" regions of my country, and to a large extent solve the problem of difficult production of horticultural crops in cold areas in winter. A type of greenhouse with independent intellectual property rights in my country. In recent years, many researchers have studied the influence of the material, thickness and height of the back wall on the thermal insulation performance of the solar greenhouse, aiming to further improve its thermal insulation performance. However, when some solar greenhouses with better thermal insulation performance are produced in late spring, summer and early autumn, the indoor tempera...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem of high indoor temperature when the solar greenhouse is in production in late spring, summer and early autumn, and to provide a method that can not only ensure the temperature requirements of the solar greenhouse in winter production, but also solve the problem of high temperature season production. It is a solar greenhouse rear wall structure with the characteristics of strong structural stability, economical and practical, etc.
