Multi-layer covering novel energy-saving greenhouse

Abstract

The invention discloses a multi-layer covering novel energy-saving greenhouse. The multi-layer covering novel energy-saving greenhouse comprises a wall body, a truss structure, an electric reel, a control motor, a solar photovoltaic plate, a photovoltaic plate bracket, a photovoltaic plate support and an engagement and disengagement device. The wall body is mounted on the ground, the truss structure stretches over the portion between the top end of the wall body and a water apron, the truss structure is covered with a plastic greenhouse film, reels of a waterproof roll, a heat preserving quiltand a colored greenhouse film are mounted above the plastic greenhouse film, the electric reel is connected with the engagement and disengagement device, the engagement and disengagement device is connected with the control motor, solar energy can be converted into electric energy by the solar photovoltaic plate, and the electric energy is stored in a storage battery to be supplied to the controlmotor. According to the energy-saving greenhouse, multiple layers of covering materials are arranged, the effects of heat preservation and crop yield and income increase are achieved, a waterproof layer can guarantee that the heat preserving quilt layer is not wet by rainwater, the heat preserving effect can be further enhanced, the covering layers are reeled through the electric reel, power of the electric reel comes from the solar energy, energy is saved, and the application value is high.

Description

technical field [0001] The invention relates to the field of agricultural greenhouses, in particular to a novel energy-saving greenhouse covered by multiple layers. Background technique [0002] Greenhouse, also known as greenhouse, can transmit light and keep warm (or warm). It is a facility for planting plants. In seasons that are not suitable for plant growth, it can provide a growth environment for the growth period of the greenhouse and increase the output of plants. It is mostly used for In the low temperature season, vegetables, flowers, forest trees and other plants are cultivated or raised. The design of the greenhouse system includes temperature increasing system, heat preservation system, cooling system, ventilation system, control system, irrigation system, etc. [0003] In the existing technology, the structure of the roof of the greenhouse with external heat preservation is mostly a truss structure. A layer of film is placed on the truss structure, and a layer ...
