Description

Light-transmitting flame-retardant energy-saving 3D climate curtain for greenhouse Technical Field The utility model relates to the technical field of curtains, in particular to a light-transmitting flame-retardant energy-saving 3D climate curtain for a greenhouse. Background The greenhouse is used as an important facility for realizing efficient crop cultivation in modern agriculture, and the environment regulation and control capability of the greenhouse directly influences the growth state and yield of crops. In a greenhouse system, the arrangement of the curtain plays a key role in heat preservation, shading, humidity control and the like. The greenhouse curtain is usually switched on and off at the top or the side wall of the greenhouse through a curtain driving system, so that parameters such as indoor illumination, temperature and humidity are adjusted according to environmental changes. In winter or cold areas, the heat preservation capability of the curtain is particularly important, so that heat loss can be effectively reduced, and the requirement of crops on illumination cannot be influenced, and therefore, the curtain material and the structural design are very important. At present, most of common greenhouse curtain products adopt a traditional single-layer heat-insulating curtain or multi-layer heat-insulating curtains. The curtain has high gram weight per unit area, so that the curtain has high requirements on a driving system, and the problems of high energy consumption, high mechanical load, high maintenance cost and the like exist. In addition, as the curtain is generally made of opaque materials, the light transmittance is poor, the demand of crops on natural light in a growth period is difficult to meet, and the photosynthesis of the crops is adversely affected especially in areas with insufficient illumination resources. Therefore, a new curtain material or structural scheme is needed in the present stage, which has good heat insulation performance and certain light transmittance in structure and can effectively reduce the weight of the whole curtain. Based on the problems, the application provides a light-transmitting flame-retardant energy-saving 3D climate curtain for a greenhouse. Disclosure of utility model Aiming at the defects of the prior art, the utility model aims to provide the light-transmitting flame-retardant energy-saving 3D climate curtain for the greenhouse, which realizes multiple balance of heat preservation, light transmission, moisture permeability and energy saving performance by alternately arranging the filling layers and the air layers.
