Greenhouse retractable ventilation window

Abstract

The invention relates to a telescopic ventilating window of a greenhouse. The telescopic ventilating window comprises fixed frames and movable frames, wherein two side end parts of each fixed frame are respectively provided with a first hollow sliding way and two side end parts of each movable frame are respectively provided with a second hollow sliding way; a first sliding rod is arranged inside each first sliding way, a second sliding rod is arranged inside each second sliding way; a first connecting frame is arranged on the end part of each first sliding rod, a second connecting frame is arranged on the end part of each second sliding rod, the corresponding first connecting frame is in direct sliding fit with the corresponding second connecting frame, and a mounting base is arranged on the side part of each first connecting frame. According to the telescopic ventilating window, the fixed frames are arranged between two arched girders of the greenhouse; the mounting bases on the first connecting frames are matched with the closer arched girder of the greenhouse for mounting by adjusting the length of fit between the corresponding first sliding rod and the corresponding first sliding way, and thus the matching among different greenhouses is met; the telescopic ventilating window is flexible and convenient to use; the telescopic ventilating window is unnecessary to independently customize and is compatible with all greenhouses; the production cost is reduced.

Description

technical field [0001] The invention relates to a ventilation window, in particular to a retractable ventilation window for greenhouses. Background technique [0002] In the greenhouse, increasing ventilation and light can effectively improve the growth speed and growth quality of crops. At present, it is realized by installing sliding windows on the top of the greenhouse. At present, the ventilation methods of the solar greenhouse mainly include: first, the upper and lower double-layer membranes are overlapped, and the ropes are fixed at the edges of the membranes, which are pulled apart by manpower when in use, which is time-consuming and labor-intensive, and cannot guarantee a consistent greenhouse environment; second, the upper and lower double-layer membranes are overlapped, The steel pipe is fixed at the edge of the upper film, and it is unwound mechanically. Since the length of a general solar greenhouse is 80-100 meters, and the longest can reach 300 meters, the ste...

Problems solved by technology

At present, the ventilation methods of the solar greenhouse mainly include: first, the upper and lower double-layer membranes are overlapped, and the ropes are fixed at the edges of the membranes, which are pulled apart by manpower when in use, which is time-consuming and labor-intensive, and cannot guarantee a consistent greenhouse environment; second, the upper and lower double-layer membranes are overlapped, The steel pipe is fixed at the edge of the upper film, and it is unwound mechanically. Since the length of a general solar greenhouse is 80-100 meters, and the longest can reach 300 meters, the steel pipe often has multiple S-shaped bends during the unwinding process, and the distance from the far end of the unwinding machine is even Can not be opened, resulting in poor ventilation; the third is the push-pull ventilation window, use the pull rod to push the window open, but due to the large temperature difference between the inside and outside of the solar greenhouse, especially in winter, it is easy to cause condensation on the window surface during ventilation Dripping water will cause damage to indoor crops, and the windows will block the wind after opening, resulting in slow communication between inside and outside

At present, the greenhouse is composed of arched beams on the top, and the distance between each arched beam is not standardized, that is, the distance between adjacent arched beams is different, and the fixing frame of the sliding window must be fixed on the arched beams. Therefore, each greenhouse The sliding windows of the greenhouse need to be customized according to the actual situation, and cannot be uniformly produced and mass-produced

Once the greenhouse is remodeled, the width of the original sliding window cannot match the new greenhouse, so that it cannot be reused, and it can only be discarded, resulting in waste
