Description

Liftable windproof skylight for greenhouse

Technical Field

The utility model relates to the field of agricultural technology, concretely relates to skylight is prevent wind with liftable to warmhouse booth.

Background

The greenhouse is a major breakthrough in agricultural technology, improves the growth environment of crops, accelerates the growth of crops, and shortens the growth cycle. The method is widely applied to various crops such as seedling breeding, vegetable planting, bud seedling culture, fruit tree cultivation and the like.

The skylight of the greenhouse is an indispensable component, and particularly has higher requirements on the double-film double-arch (framework) double-covered greenhouse in spring and strong wind seasons. At present, the known double-film double-arch (framework) double-quilt greenhouse mainly has two types: one is a double-layer greenhouse with walls. The structure is that the east-west wall and the rear wall are built by hard wall buildings such as masonry, rammed earth, polystyrene board and the like and heat insulation materials, and a small ventilation window is left in the rear wall, and some rear walls do not exist; the front roof adopts a heat preservation mode of double films, double arches (frameworks) and double quilts; the back roofing can not lift and roll up for the vast majority. The other is a wall-free and ground-inserting type double-layer greenhouse. The structure is that the east-west wall and the rear wall are built by a profile steel framework, a heat preservation quilt, a soft wall building and heat preservation materials, and the rear wall is not provided with a ventilation window; the front roof adopts a heat preservation mode of double membranes, double arches (frameworks) and double quilts, and the rear roof cannot be lifted and rolled up.

The air release modes of the above greenhouses mainly include two types: one is (automatic control of temperature control air release device) curtain type air release. The structure of the greenhouse is composed of two overlapped greenhouse films (a big film and a tuyere film) on a front roof of the greenhouse, a tuyere rope, a curtain pulling rope, a fixed pulley, a temperature control automatic air discharger and a rolling rod. The other is (automatic control of the temperature control air release device) rack push-pull side front open type air release. The structure of the automatic air release device consists of an air release opening sliding window, a window opening four-piece set, a temperature control automatic air release device and a rolling bar.

The common disadvantages of the two double-layer greenhouses are as follows:

firstly, the air release opening is not windproof. The orientation of the greenhouse is generally 5-8 degrees in the south and the west, and is the direction towards the air opening, and particularly in areas with more early spring and strong wind weather, the contradiction between 'air release' and 'wind prevention' cannot be solved. The air is not discharged, and the temperature in the greenhouse is high; and (5) releasing air, and tearing the plastic greenhouse film at the air opening by strong wind. In order to prevent the greenhouse film from being torn in the greenhouse by the strong wind from the wind release opening, the air release opening is used for releasing the heat preservation quilt.

Secondly, the air outlet is not rainproof. The 'air release openings' of the two air release modes are not tightly closed, rain is leaked in heavy rain weather, a 'water pocket' is easily formed at the 'air release opening' position, a shed film is damaged by pressure, and three contradictions of 'air release', 'wind prevention' and 'rain prevention' cannot be solved in case of weather intermission of wind and rain.
