Framework of agricultural greenhouse, with function of heat storage

Abstract

The invention discloses a framework of an agricultural greenhouse, with the function of heat storage, and relates to a framework of an agricultural greenhouse. The framework consists of heat storage headers, rising discharge pipes, a rising header pipe, declining straight pipes, a declining header pipe, declining bent pipes and supporting stand columns, wherein the rising discharge pipes are arranged in an inverted V shape on the left side and the right side of the rising header pipe, the lower ends of the rising discharge pipes are connected to branch output interfaces of the heat storage headers, and the upper ends of the rising discharge pipes are connected to branch input interfaces of the rising header pipe; the declining straight pipes are connected to a position between a backwater outlet in the bottom of the rising header pipe and a backwater inlet in the top of the declining header pipe; the declining bent pipes are arranged on the left side and the right side of the declining linking box pipe in an arched manner, the upper ends of the declining bent pipes are connected to loop output interfaces of the declining header pipe, and the lower ends of the declining bent pipes are connected to loop input interfaces of the lower parts of the heat storage headers. Through the use of the framework disclosed by the invention, solar energy heat is stored in the framework, and when the temperature in the greenhouse is lowered at night, the heat is gradually released, so that the temperature drop range in the greenhouse is reduced, and a diurnal temperature difference in the greenhouse is reduced.

Description

technical field [0001] The invention relates to an agricultural production equipment, in particular to a skeleton of an agricultural greenhouse. Background technique [0002] The agricultural greenhouse is a frame-covered structure with thermal insulation properties. Its appearance allows people to eat off-season vegetables and fruits. Generally, agricultural greenhouses use a bamboo structure or a steel structure frame, covered with one or more layers of thermal insulation plastic film, thus forming a greenhouse space. The outer film can well prevent the loss of carbon dioxide produced by the growth of vegetables inside, so that the shed has a good heat preservation effect. [0003] When there is sunshine during the day, the temperature in the agricultural greenhouse is very high, and at night, affected by the cooling of the environment, the temperature in the greenhouse is too low, and the temperature difference between day and night is large, which is not conducive to th...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to make up for the large temperature difference between day and night in the existing agricultural greenhouses, and provide an agricultural greenhouse framework with heat storage function. When there is sunshine in the daytime, the heat of solar energy is stored in the framework, and the temperature in the greenhouse decreases at night. Gradually release heat, reduce the cooling range in the greenhouse, reduce the temperature difference between day and night in the greenhouse, create an environment conducive to the growth of fruits and vegetables, and improve the quality and output of fruits and vegetables
