Dual-layer warming shed

Abstract

A dual-layer hot shed for planting plant in the winter structurally features that its semi-arched frame has longitudinal slots on its external arch surface and longitudinal convex strips on its internal concove surface, the thick rods are laid on columms with concove tops, the thin rods are inserted in concave holes on ground shoes, and two layers of insulating film are respectively fixed to said longitudinal slots and convex strips. Its advantages are simple structure, easy installation and long service life.

Description

technical field [0001] The invention relates to plant cultivation technology, in particular to the improvement of a thermal insulation greenhouse used for plant cultivation in winter. Background technique [0002] The thermal insulation greenhouse is a warm-keeping facility used to cultivate plants in winter or in colder weather. It allows the crop seedlings, vegetables and fruits cultivated by the operator to grow and mature in a timely manner according to demand, and form fruits. The greenhouse of this thermal facility is usually a single-layer thermal insulation structure, that is, thermal insulation film is laid on the scaffolding. Its main disadvantage is that the single-layer insulation film coverage leads to poor insulation performance, and it is necessary to add straw curtains to keep warm at night, which increases the load on the scaffolding of the greenhouse, especially in winter when there is snow. (Frequent opening and closing of the straw curtain is also easy t...

AI Technical Summary

Problems solved by technology

Its main disadvantage is that the insulation performance is poor due to the coverage of a single layer of insulation film. At night, straw curtains need to be added to keep warm, which increases the load on the scaffolding of the greenhouse. Especially in winter, the presence of snow will further increase the load of the scaffolding, which is not only easy to damage the insulation film. (Frequent opening and closing of the straw curtain is also easy to damage the insulation film), and it will cause the scaffolding to collapse and be damaged, which will reduce the service life, bring inconvenience to the operator and waste the economy, etc.
