Sunlight greenhouse heat insulation structure

Abstract

The invention discloses a sunlight greenhouse heat insulation structure which comprises an outer heat insulation quilt, an inner heat insulation quilt, a front end heat insulation structure and a rear end heat insulation structure. The outer heat insulation quilt is geotextile laid outside a greenhouse. The inner heat insulation quilt is an inflatable heat insulation quilt erected inside the greenhouse. The front end of the greenhouse is the direction end of sunlight radiation towards the greenhouse, and the front end heat insulation structure is arranged on the internal edge of the front end of the greenhouse and comprises a water heating structure and a hot air structure arranged on the edge of the front end of the greenhouse. The rear end of the greenhouse is opposite to the front end of the greenhouse, and the rear end heat insulation structure is arranged on the internal edge of the rear end of the greenhouse and is filled with heat insulation sand and heat insulation bags. The sunlight greenhouse heat insulation structure is provided with the front end heat insulation structure actively supplementing heat at the large-heat-loss front end of the greenhouse and is provided with the rear end heat insulation structure filled with the heat insulation sand and the heat insulation bags at the small-heat-loss rear end of the greenhouse, integrates the front end heat insulation structure, the rear end heat insulation structure and internal heat insulation and ensures a constant-temperature environment of the greenhouse.

Description

technical field [0001] The invention relates to the technical field of greenhouse heat preservation, in particular to a solar greenhouse heat preservation structure. Background technique [0002] The winter temperature in the north is low, and heaters such as boilers are usually used to continuously heat the greenhouses for planting crops so that the greenhouses can reach and maintain the temperature required for plant growth. In order to reduce the loss of heat and energy, in rainy and snowy weather or at night, insulation materials such as grass curtains, insulation quilts, geotextiles and other insulation materials are laid on the greenhouse body for insulation. However, there is still a lot of heat radiating outward through the greenhouse floor. [0003] Aiming at the problem of radiating heat from the greenhouse floor to the outside, the usual practice in the prior art is to dig a cold-proof ditch on the ground close to the wall inside or outside the greenhouse, and th...

Problems solved by technology

However, this kind of cold-proof ditch can only do simple cold insulation, and cannot actively supplement heat for the greenhouse. Moreover, when the temperature drops sharply, there is no proper heat supplement, and the cold-proof effect is very poor.
