Semi-removable greenhouse back wall

Abstract

The invention discloses a semi-detachable greenhouse rear wall structure, comprising a lower half-section composite wall body and an upper half-section detachable wall body. The lower half-section composite wall body is sequentially composed of a heat dissipation layer and a heat storage layer from inside to outside. and the thermal insulation layer; the dismountable wall body includes a rear wall column support structure, and removable inner jute fiberboards and outer jute fiberboards respectively arranged on the inner and outer sides of the rear wall column support structure. The jute fiberboard can be installed and disassembled freely. Installing the jute fiberboard in winter can reduce indoor heat loss and play a role in thermal insulation; removing it in summer can increase the ventilation area of ​​the greenhouse, thereby effectively reducing the indoor temperature. By using the invention, both winter production and summer production can be carried out in the area of ​​Jiangsu, the problem that annual production cannot be carried out in southern greenhouses is solved, and the utilization rate of land is improved. Improve economic efficiency.

Description

technical field [0001] The invention relates to a solar greenhouse wall, in particular to a semi-detachable greenhouse rear wall. Background technique [0002] Solar greenhouse is a unique horticultural facility in my country. In winter in cold regions, off-season vegetable cultivation can be carried out even without heating. This mainly depends on the thermal insulation structure of solar greenhouse. The thermal insulation structure of solar greenhouse is mainly Back walls and back slopes, back walls and back slopes increase the indoor temperature by using some thermal insulation materials. The development of solar greenhouses is relatively mature, especially in northern my country. In recent years, Jiangsu area has also begun to develop and use solar greenhouses on a large scale, but most of the solar greenhouse structures are not optimized or designed according to local climatic conditions. At present, most of the back walls of solar greenhouses in my country are fixed ma...

Problems solved by technology

The development of solar greenhouses is relatively mature, especially in northern my country. In recent years, Jiangsu has also begun to develop and use solar greenhouses on a large scale, but most of the structures of solar greenhouses have not been optimized or designed according to the local climate conditions.

At present, the back walls of solar greenhouses in my country are mostly fixed masonry structures, especially in the summer of Jiangsu. The heat storage and heat insulation performance of the walls causes the indoor temperature to be too high, resulting in a high idle rate of the greenhouses, which prevents annual production and wastes Land Resources
