Sunshade device for glass greenhouse

Abstract

The invention discloses a sunshade device for a glass greenhouse. The device comprises four bases, toothed plates and fixing frames, wherein the toothed plates penetrate through the tops of inner cavities of the bases; the tops of the toothed plates penetrate through the tops of the bases and are fixedly connected with the fixing frames; the four bases are positioned at the four corners of the bottoms of the fixing frames respectively; a shell is fixedly connected with the tops of the portions, between the left and right opposite sides, of the fixing frames; a double-shaft motor is fixedly connected with the middle end of the bottom of an inner cavity of the shell. According to the device, the fixing frames, a threaded rod, a threaded sleeve, a speed reducing motor, a time controller, a sun shield, baffles, iron blocks, mounting grooves, high-light-transmission glass and magnet plates are matched for use, so that the problems are solved that when plants are planted in a glass greenhouse, vegetation needs daylighting in different degrees according to conditions, when the sunlight is too strong, the vegetation is insolated and thus withered, and therefore the vegetation cultivation effect of the glass greenhouse is declined.

Description

technical field [0001] The invention relates to the technical field of glass greenhouses, in particular to a sunshade device for glass greenhouses. Background technique [0002] Glass greenhouse is a greenhouse with glass as the main light-transmitting covering material. It belongs to a type of greenhouse with a long service life. It is suitable for various regions and various climates. It is divided into various greenhouses for planting different plants. The glass greenhouse structure mainly includes Greenhouse foundation, greenhouse steel structure and aluminum alloy structure, etc. [0003] When planting plants in a glass greenhouse, the vegetation needs to be illuminated to varying degrees according to the situation. When the sunlight is too strong, the vegetation will be exposed to the sun, causing the vegetation to wither, thereby reducing the vegetation cultivation effect of the glass greenhouse. Contents of the invention [0004] The purpose of the present inventi...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a sunshade device for glass greenhouses, which has the advantage of being able to shade the sun, and solves the problem that when planting plants in a glass greenhouse, the vegetation needs to be illuminated to different degrees according to the situation. When the sunlight is too strong, it will damage the The vegetation is exposed to the sun, causing the vegetation to wither, thereby reducing the problem of the cultivation effect of the glass greenhouse vegetation
