Sunshade

Abstract

The invention discloses a sunshade, which comprises a support, a shed body and a cooling component, wherein the support comprises two longitudinal rods, two curved rods and a plurality of cross rods connected between the two longitudinal rods and between the two curved rods; the shed body is arranged between two curved rods; the cooling component comprises a plurality of spray pipelines respectively mounted on each cross rod connected between the two curved rods and a plurality of atomizing nozzles communicated with the spray pipelines, and a filter screen is connected to one end of a water inlet of each the spray pipeline in a detachable manner; fixing components are arranged at the end parts of the longitudinal rods and the curved rods, the fixing components comprise a sleeve which can be connected with the end parts of the longitudinal rods and the curved rods in a sliding and sleeved manner, and a plurality of inserting rods which can extend or retract into the end parts of the longitudinal rods and the curved rods, first inclined holes which are equal to the number of the inserting rods are formed in the side walls of the end parts of the longitudinal rods and the curved rods; second inclined holes which are equal to the number of the first inclined holes and have the same slope are formed in the side wall of the sleeve, when the first inclined holes and the second inclined holes are on the same oblique line, the inserting rods penetrate through the second inclined holes from the first inclined holes.

Description

technical field [0001] The invention relates to the technical field of greenhouse cooling, in particular to a sunshade. Background technique [0002] The traditional sunshade net achieves cooling by reducing the intensity of light transmitted through, and its cooling range is positively correlated with the shading rate, and the cooling range is small; the traditional insect-proof net has a high light transmittance, and the cooling range is very limited. [0003] In addition, traditional sunshade nets and insect nets are commonly used in greenhouses. The material of the net is hydrophobic resin. The water falling on the net cannot spread along the surface of the net to form a water film, but penetrates the mesh in the form of water droplets. It drips vertically, so it cannot cool down by guiding the water film to evaporate on the surface of the mesh body, and the cold energy in the water film passes through the mesh and convects the hot air in the greenhouse. [0004] In vie...

[0003] In addition, traditional sunshade nets and insect nets are commonly used in greenhouses. The material of the net is hydrophobic resin. The water falling on the net cannot spread along the surface of the net to form a water film, but penetrates the mesh in the form of water droplets. Vertical dripping, so it is impossible to cool down by guiding the water film to evaporate on the surface of the mesh body, and the cold energy in the water film passes through the mesh and convects the hot air in the greenhouse
