Light-adjustable folding type diffusing glass greenhouse photovoltaic sunshade curtain

Abstract

The invention relates to a light-adjustable folding type diffusing glass greenhouse photovoltaic sunshade curtain. The curtain includes a central control system and a sunshade curtain device which are arranged in a greenhouse; the central control system comprises a main control node, a sunshade driving node and a plurality of light monitoring nodes, wherein the main control node, the sunshade driving node and the light monitoring nodes are in wireless connection, and the main control node is used for analyzing collected data of the real-time light intensity in the greenhouse, the sunshade driving node and the light monitoring nodes are connected for the real-time adjustment of the expansion and contraction quantity of a rack in the sunshade curtain device, the light monitoring nodes are arranged in corresponding positions in the greenhouse and used for the real-time acquisition of the greenhouse light intensity data, and the sunshade curtain device comprises a rack, a folding frame, a gear motor, a support body and several thin film solar battery panels. According to the change of illumination environment in the greenhouse, a photovoltaic thin film sunshade mechanism can automatically stretch and retract, and by the fine adjustment of the light transmitting area of photovoltaic power generation equipment, an ecological environment suitable for plant growth in the greenhouse is created.

Description

technical field [0001] The invention relates to the field of agricultural facilities, in particular to a foldable diffuse glass greenhouse photovoltaic sunshade with adjustable illumination. Background technique [0002] Greenhouse is a semi-closed system that creates a suitable environment for plant production. It can improve the growth environment of plants, promote the growth and development of plants, improve yield and quality, and is widely used in crop breeding, vegetable and flower cultivation, nursery stock cultivation and off-season fruits and vegetables. planting etc. The key technology for greenhouses to provide a suitable climate environment for plant growth lies in the regulation of the internal environment of the greenhouse, and the light environment is one of the most important factors, and it is also the energy source for plant growth. Illumination affects various aspects of plant growth and development, morphogenesis, gene expression, etc., and is the mos...

AI Technical Summary

Problems solved by technology

However, in existing photovoltaic greenhouses, whether it is laying opaque or semi-transparent solar panels on the roof of the greenhouse or intermittently arranging solar panels and light-transmitting materials on the roof, it will lead to insufficient light and insufficient light in the greenhouse. Unevenness, which affects the yield and quality of plants, especially in winter and rainy days

In addition, the intermittent arrangement of solar panels on the roof will also cause alternating light and dark shadows in the greenhouse. When the sun moves in the sky, these shadows will also move with it, causing periodic changes in the light intensity of the plants in the greenhouse. Stress response in plants, thus affecting the normal growth and development of plants
