Secondary air inflation thermal insulation device for agricultural greenhouse glass wall

Abstract

The invention relates to a secondary air inflation thermal insulation device for an agricultural greenhouse glass wall. The secondary air inflation thermal insulation device comprises a greenhouse (1), and the greenhouse (1) is provided with the glass wall (2). The secondary air inflation thermal insulation device is characterized in that a group of air cushions (3) are arranged on the inner sideof the glass wall (2), each of the two sides, parallel to the glass wall (2), of each air cushion (3) is provided with a group of guy ropes (6), a pressing rod (4) is arranged above each air cushion (3), each of the two ends of each pressing rod (4) is connected to a group of saddle weights (5), a group of vertical gas columns (3a) connected to external air inflation equipment are arranged in a cavity of each air cushion (3), an air faucet (3b) connected to the air inflation equipment is also arranged at the bottom of each air cushion (3), and the bottom of each air column (3a) is connected tothe external air inflation equipment through an air supply pipe (3c). The secondary air inflation thermal insulation device has the advantage of being low in cost, capable of being applied to large-scale implementation and capable of meeting the illumination intensity in the daytime and the heat preservation property at night.

Description

technical field [0001] The invention relates to the technical field of intelligent agricultural equipment, in particular to a secondary inflation and heat preservation device for agricultural greenhouse glass walls. Background technique [0002] In the field of smart agriculture, greenhouse cultivation is expanding day by day. In order to obtain the sunlight needed by the plants, the roof and walls of the entire greenhouse are made of transparent glass plates. Since the glass plates used are thin and have poor thermal insulation, the heating cost of the greenhouse is high. [0003] Greenhouse planting requires light during the day and heat preservation at night. If heat preservation measures are taken, it will affect the daylight; if no heat preservation measures are taken, it will affect night heat preservation. Therefore, a movable insulation wall is needed. During the day, the wall falls to receive light, and at night, the wall is pulled up to isolate and keep warm. ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the existing greenhouse insulation wall cannot take into account both daylight and night insulation, and provides a secondary air-filled insulation device for agricultural greenhouse glass walls, which is not only low in cost, but also suitable for large-scale implementation. , and can meet the daytime illuminance and night heat preservation
