Description

A kind of last volume membrane type ventilation skylight for Protectorate cultivation greenhouse

Technical field

The utility model category Protectorate cultivation facility technology field, provides a kind of simple easy for Protectorate cultivation greenhouse With the good ventilation skylight of, effect.

Background technology

The Protectorate cultivation of the industrial crops such as fruit tree, especially plastic film shed cultivation development are rapid.These protecting fields Cultivation greenhouse usually sets ventilation skylight to adjust temperature.The ventilation skylight applied at present has wound membrane formula and unilateral movable, unilateral Movable is to fix one end, other end activity using loose-leaf, is jacked up by drawstring pull-up or waddy, the drawback is that running into some During the strong wind of wind direction, wind can be subject to skylight top cover blocks to enter in canopy, the problems such as causing eardrum, and be possible to cause infringement；Mesh Preceding wound membrane formula ventilation skylight be all upward wound membrane open, drops down membrane closure, easy ponding when raining.In long and narrow ventilation A large amount of ponding exclude difficult on skylight.For this reason, the utility model proposes a kind of downward wound membrane for Protectorate cultivation greenhouse Formula ventilation skylight, downward wound membrane opens, membrane closure is unfolded upwards, when overcoming rainy the shortcomings that easy ponding.

The content of the invention

The utility model does not accumulate when providing a kind of simple in structure, easy to use, rainy for Protectorate cultivation greenhouse facility The downward wound membrane formula ventilation skylight of water.The skylight is by greenhouse bracket, awning film, canopy film indent, long and narrow skylight frame, skylight canopy Film, skylight film-coiling device wound membrane bar, film-coiling device operation turntable, vertical columns and anti-bird net composition.

Technical solution is used by the utility model solves the problems, such as：Skylight by greenhouse bracket, awning film, canopy film indent, The long skylight frame of 40~60 centimetres of widths, skylight canopy film, skylight film-coiling device wound membrane bar, film-coiling device operation turntable, vertical columns, press mold Rope and anti-bird net composition, operation turntable can promote up and down along vertical columns, and top greenhouse bracket is ogive frame structure, arch Awning film is covered above body, long and narrow ventilation skylight is opened up on awning film, skylight frame the right and left frame is greenhouse bracket, respectively distance 100~130 centimetres of greenhouse both ends, skylight frame upper side frame is welded on greenhouse bracket, apart from 30~45 lis of greenhouse bracket top Rice, skylight frame lower frame and greenhouse equal length, are also welded on greenhouse bracket；Fixed canopy film indent on the inside of skylight frame surrounding, The awning film press-in canopy film indent of skylight frame surrounding；Also canopy film indent, skylight canopy film lower end folding are fixed on the outside of skylight frame lower frame The outside canopy film indent is pressed into from inner side after curved, press mold bar is located within skylight canopy film, the skylight canopy film of making compares skylight frame It is 25~40 centimetres wide, 90~115 centimetres are each side grown than skylight frame to cover greenhouse membrane closure skylight, skylight canopy film volume It is wound on wound membrane bar；Film-coiling device turntable is operated by the downward wound membrane of skylight canopy film to skylight frame lower frame position, opened skylight；Operation By skylight canopy film, expansion crosses 20~35 centimetres of skylight frame upper side frame position, to apart from greenhouse bracket top to film-coiling device turntable upwards 10 centimeters stop, and close skylight, and film pressing rope is used to fix wound membrane bar and awning film, and skylight canopy film is arrived apart from greenhouse bracket upwards It is that strong wind causes infringement in order to prevent that 10 centimeters of top, which stop,；The canopy film indent that anti-bird net is pressed on the inside of skylight frame surrounding is prevented Only bird endangers.

The beneficial effects of the utility model are：When skylight is closed, wound membrane bar rains apart from only 10 centimetres of greenhouse bracket top When wound membrane bar more than receive rainwater face and be substantially reduced than current upper wound membrane formula ventilation skylight, a small amount of rainwater of receiving passes through wound membrane Gap between bar and awning film enters greenhouse, not ponding substantially at skylight of ventilating；When skylight is opened, rainwater can enter greenhouse, Ventilate at skylight also not ponding；(2) it can prevent bird from endangering；(3) the utility model has the spy that facility is simple, operation operation is easy Point, is a simple and practical new facility.
