Skylight opening and closing structure of greenhouse

Abstract

The invention discloses a skylight opening and closing structure of a greenhouse. The skylight opening and closing structure comprises a skylight structure arranged in the greenhouse; the skylight structure comprises a fixed bracket; a floating bracket is arranged in the middle of the fixed frame; two ends of the floating bracket are arranged in an installation cavity formed in the inner side end surface of the fixed bracket separately; more than one spring is arranged in the installation cavity; one end of each spring is connected with the inner wall of the installation cavity and the other end is connected with the outer wall of the floating bracket; a ventilation cavity is arranged in the middle of the floating bracket; more than one sealing plate is arranged in the ventilation cavity; the whole ventilation cavity is sealed by various sealing plates; and a suction structure is arranged between the sealing plates. According to the skylight opening and closing structure of the greenhouse, opening and closing of a skylight can be effectively achieved, a traditional thin-film skylight form is changed, good anti-wind capability and anti-collision capability can be achieved, the skylight opening and closing structure is very convenient to open and the problem of accumulated water is solved.

Description

technical field [0001] The invention relates to the field of greenhouses, in particular to a skylight opening and closing structure for greenhouses. Background technique [0002] In the greenhouse, more than one skylight will be set in the middle of the greenhouse. These skylights are mainly used for ventilation and to connect the greenhouses on both sides. When the weather is hot, the skylight can be opened to realize heat dissipation. When the skylight in the prior art dissipates heat, It is very inconvenient to open. The film technology is used to seal the skylight. Although the cost of the film is low for one use, if it is often damaged and replaced, it does not actually save much cost. Instead, it has been spent on labor and increased costs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method of using glass instead of plastic film, which can also achieve buffering and anti-extrusion capabilities, is ver...

[0002] In the greenhouse, more than one skylight will be set in the middle of the greenhouse. These skylights are mainly used for ventilation and to connect the greenhouses on both sides. When the weather is hot, the skylight can be opened to realize heat dissipation. When the skylight in the prior art dissipates heat, It is very inconvenient to open. The film technology is used to seal the skylight. Although the cost of the film is low once, if it is often damaged and replaced, it does not actually save much cost. Instead, it has been spent on labor and increased costs.
