A kind of skylight for self-shading sprinkler cooling glass greenhouse

Abstract

The invention discloses a skylight for a self-shading and sprinkler cooling type glass greenhouse, which comprises a window frame, the inner wall of the window frame is symmetrically and fixedly connected with glass, and the inner wall of the window frame is fixedly connected with a conductive plate, and the conductive plate is made of indium tin oxide material, the window frame is provided with a sliding plug cavity, the inner wall of the sliding plug cavity is slidably connected with a magnetic sliding plug, the top of the sliding plug cavity is fixedly connected with the upper end of the magnetic sliding plug through a spring, and the sliding plug cavity The inner wall is embedded with a helical coil. In the present invention, the airfoil plate drives the magnetic sliding plug to slide up and down, and then an induced current is generated on the spiral coil, and the temperature on the conductive plate rises, so that the concentration of charge carriers on the conductive plate increases sharply, and the transparency of the conductive plate decreases, which is beneficial to The external sunlight is blocked, and when the magnetic sliding plug slides up and down on the inner wall of the sliding plug cavity, the external water will be continuously pumped into the annular cavity and sprinkled from the water spray hole to sprinkle water on the plants in the greenhouse to avoid excessive temperature. Plants die from dehydration at higher temperatures.

Description

technical field [0001] The invention relates to the technical field of glass greenhouses, in particular to a skylight for a self-shading and water-sprinkling cooling type glass greenhouse. Background technique [0002] The glass greenhouse is a kind of greenhouse with glass as the main covering and steel structure as the frame. Because the glass greenhouse has the characteristics of long service life, large lighting area, uniform illumination and suitable for use in various regions and various climatic conditions is widely used. [0003] The plants in the glass greenhouse accept the sunlight from the glass to grow through photosynthesis, but in the hot summer, the sunlight is strong, which makes the plants automatically shut down the photosynthesis system and stop growing, and it is easy to make the greenhouse under strong sunlight. The indoor plants are short of water. Therefore, at present, the cooling of the glass greenhouses in summer is mostly carried out by artificial...

[0003] The plants in the glass greenhouse accept the sunlight from the glass to grow through photosynthesis, but in the hot summer, the sunlight is strong, which makes the plants automatically shut down the photosynthesis system and stop growing, and it is easy to make the greenhouse under strong sunlight. The indoor plants are short of water. Therefore, at present, the cooling of the glass greenhouses in summer is mostly carried out by artificially laying sunshade nets to cool the glass greenhouses. Working in high temperature weather is prone to heatstroke. In addition, passive shading and cooling of glass greenhouses cannot be laid and dismantled in time according to the production conditions of the plants in the greenhouses, which will affect the growth efficiency of plants.
