Problems solved by technology
The currently used ventilating skylights include roll film type and single-side movable type. The roll-membrane type tends to accumulate water when it rains. The single-side movable type uses a loose leaf to fix one end and move the other end. It is pulled up by a pull cord or a stick. Its disadvantage is that when encountering strong winds in certain wind directions, the wind will be blocked by the top cover of the skylight and enter the shed, causing problems such as eardrums, and may cause damage

Embodiment
[0009] Such as figure 1 As shown, a rectangular base support 1 with a length of 1.45 meters and a width of 0.45 meters is welded with a galvanized square steel pipe of 2.5 cm. On the top, the four corners of the rectangle are welded with four 0.10-meter-high base sleeves 2 with galvanized square steel pipes of 3.0 cm in size. The fixed film pressure grooves under the four sides of the rectangle are used to hold down the greenhouse film, which is biased to one side in the middle of the two long sides of the rectangle. Weld a pulley bracket 3 at 2 cm, fix a pulley 4 on the pulley bracket, fix one end of the stay rope 5 to the stay rope fixing point 6 of the window cover part, pull the skylight through the pulley 4 and push up the column 7, and open the skylight after the column goes up.
[0010] Weld a rectangular skylight bracket 8 with a length of 1.45 meters and a width of 0.45 meters with a 2.0 cm galvanized square steel pipe. A layer of rubber is bonded to the upper and low...

The invention provides a ventilation skylight which is simple, easy to use and good in effect for a protected cultivation facility plastic film greenhouse. The skylight comprises a base part and a skylight cover part. The base part comprises a base support, a film pressing groove, base sleeves, a pulley support, pulleys and pulling ropes. The skylight cover part comprises a skylight top cover, a skylight upward pushing support, a skylight upward pushing stand column, pulling rope fixing points and skylight column legs. The skylight cover part is connected with the base part in the mode that the skylight column legs are inserted into the base sleeves, the skylight upward pushing stand column is pulled through the upward pushing pulling rope, the stand column moves upwards, and the skylight is opened; after the upward pushing pulling rope is released, the downward pulling rope is pulled, and the skylight cover descends and is sealed. The ventilation skylight has the advantages of being simple in structure, convenient to use and good in effect.
Description
technical field [0001] The invention belongs to the technical field of cultivation facilities in protected areas, and provides a ventilation skylight which is easy to use and has good effect for the cultivation greenhouses in protected areas. Background technique [0002] The protected cultivation of economic crops such as fruit trees, especially the cultivation of plastic film greenhouses has developed rapidly. These protected cultivation greenhouses are usually provided with ventilation skylights to adjust the temperature. The currently used ventilating skylights include roll film type and single-side movable type. The roll-membrane type tends to accumulate water when it rains. The single-side movable type uses a loose leaf to fix one end and move the other end. It is pulled up by a pull cord or a stick. Its disadvantage is that when encountering strong winds from certain wind directions, the wind will be blocked by the top cover of the skylight from entering the shed, ca...
