When the greenhouse is used, various types of greenhouses can be used, the greenhouse can be in the form of a wall surface film (such as a film is arranged on the front side alone or is arranged on the front side and the upper side, and the front side is the side facing the south), or the front side, the rear side and the upper side of the greenhouse are both films, the left side, the right side and the right side are structures such as walls, when the front side, the rear side and the upper side are both films, the air supply adjusting devices can be arranged on the front side, the rear side and the front side, the positions of the ventilation windows 9 on the front side and the rear side can be independently adjusted, the ventilation windows 9 on the front side and the rear side at different height positions enable different air circulation paths to be generated in the greenhouse, and the internal air circulation is enhanced. The description will be made by taking one side as an example. The greenhouse support can be an upright vertical surface or an arc surface, and the guide rod 1 is matched with the greenhouse support in shape for guiding. The description will be made taking the front side between the greenhouses as an upright state as an example.

The upper end of the upper film 2 is fixed at the upper end of the greenhouse support, the lower end of the lower film 3 is fixed at the lower end of the greenhouse support, the guide rod 1 is erected beside the greenhouse support, the first film end 201 and the second film end 301 can be fixedly provided with a reel along the left-right direction, the reel is coaxially connected with a film winding shaft, the film winding shaft drives the reel to rotate, the upper film 2 or the lower film 3 is wound or released, and the upper film 2 and the lower film 3 are wound on the film winding shaft through the reel. In the initial state, the sliding frame 4 can be located at the middle position of the moving stroke, and at the moment, the multi-ring film 2 or the lower film 3 is respectively wound on the two film winding shafts as redundancy. As shown in fig. 4, when ventilation is required, the sliding frame 4 slides on the guide rod 1 to adjust the height position, initially positions the height position of the ventilation window 9, and then slidingly adjusts the distance and position between the two sliding seats 5, and the positions of the two sliding seats 5 determine the height of the ventilation window 9 and the opening of the ventilation window 9 due to the certain length of the sliding rail. As shown in fig. 5, when sealing is required, the two slide bases 5 move close to each other, so that the upper film 2 and the lower film 3 on the two film winding shafts abut to form a seal.

In the height adjustment process of the ventilation window 9, the length of the upper film 2 or the lower film 3 is changed, the film winding shaft is adapted to roll or release, for example, when the ventilation window is adjusted upwards, the upper film 2 is rolled by the film winding shaft on the upper side, and the lower film 3 is released by the film winding shaft on the lower side, so that the ventilation window can move upwards. When two slide bases 5 keep away from, two roll up membrane axle and roll up upper film 2 and lower film 3 respectively, realize keeping away from, form ventilation window 9 in the middle.

When both sides all set up this air supply adjusting device around warmhouse booth, can adopt the following ventilation mode, the front side forms ventilation window 9 in the below, and the rear side forms ventilation window 9 in the top, and then inside air circulation from top to bottom strengthens, when needs keep away below plant and carry out the circulation of air, then both sides all form ventilation window 9 in the top around can.

The upper film 2 and the lower film 3 are both films, and the common films are transparent materials, and have a certain shading effect although light is transmitted, so that the damage of direct irradiation of strong light to plants can be shielded and reduced mainly under the action of strong light, at the moment, the ventilation window 9 is directly penetrated by the strong light, the position regulation of the ventilation window 9 is very high, and the probability of direct irradiation of the strong light to plants can be reduced.

When the film is damaged, the film can be timely made up. For example, when the position of the upper film 2 close to the film winding shaft is locally damaged, and at the moment, the upper film winding device 6 cannot be integrally replaced or seam-repaired, and the upper film winding shaft is started to wind more upper films 2, so that the damaged position is wound on the film winding shaft, no air leakage is caused, and at the moment, the lower film winding shaft releases the lower films 3 with the same amount, and the lower film winding shaft moves upwards to continuously keep abutting and sealing with the upper films 2.

Further, the guide rails comprise a first guide rail 402 and a second guide rail 403, a guide ring 4041 is arranged in the middle of the sliding frame 4, the first guide rail 402 and the second guide rail 403 are positioned on two sides of the guide ring 4041, the guide rail further comprises a rotating frame 405 which is rotatably arranged in the guide ring 4041, a third guide rail 4051 is arranged on one side of the rotating frame 405 and used for connecting the first guide rail 402 and the second guide rail 403, the sliding seats 5 and the third guide rail 4051 are slidably arranged, and when the two sliding seats 5 are simultaneously positioned on the third guide rail 4051, the two sliding seats 5 rotate along with the rotating frame 405. The middle part of the sliding frame 4 is provided with a sleeve 404, the guide ring 4041 is annular and is positioned on the inner wall of the sleeve, and the outer side of the rotating frame 405 is rotationally sleeved on the guide ring 4041.

In use, rotation of the turret 405 causes the two film reels 6 to rotate about a central position, changing the configuration of the ventilation window 9 as well as the sealing configuration. The upper film winding shaft is a first film winding shaft 601, the lower film winding shaft is a second film winding shaft 602, the two film winding shafts are symmetrically arranged, the upper side of the guide rail is a first guide rail 402, the lower side of the guide rail is a second guide rail 403, and a third guide rail 4051 is positioned between the first guide rail 402 and the second guide rail 403.

As shown in fig. 6, when two sliding bases 5 are both on the third guide rail 4051 on the rotating frame 405 and are separated from each other by a distance to form the ventilation window 9, the rotating frame 405 rotates 90 ° counterclockwise, at this time, the first film winding shaft 601 is away from the greenhouse support, the end of the upper film 2 is lifted, the second film winding shaft 602 is close to the greenhouse support, and the direction of the ventilation window 9 is changed from forward to downward. The ventilation window 9 with the downward or upward wind direction is generally in the horizontal direction, so that the risk of strong wind irrigation can be reduced, and the effect of direct light entering the greenhouse and shielding rain can be reduced when the ventilation window is downward.

As shown in fig. 7, when sealing is required, the two sliding bases 5 are located on the rotating frame 405 and are close to each other, at this time, the rotating frame 405 rotates 180 ° (not limited to 180 °) counterclockwise, and then the first film winding shaft 601 rotates below the second film winding shaft 602, and the upper film 2 covers the lower film 3 to form a staggered encircling sealing mode, so that the sealing contact area is enlarged, the positions are increased, the sealing effect can be greatly improved, and the air leakage and rain leakage conditions are reduced. In the drawings, the sealing positions are widely spaced for clarity of illustration of the boundaries of the structures, but in the stretched state of the upper film 2 and the lower film 3, the structure in which the sealing positions abut against each other at a plurality of positions is clearly known to those skilled in the art.

When the two circles are abutted against each other or the two circles are staggered and encircling, air leakage is likely to exist on the left side and the right side of the film, for example, when the two circles are abutted against each other, the contact area can be enlarged by deformation, but a position which cannot be abutted against the seal is likely to exist due to structural limitation, namely, the air leakage position is the air leakage position, but the area of the air leakage position is smaller, and the air leakage position can be closed by the existing shielding mode or the mode of pressing the upper film 2 and the lower film 3.

Further, the first rail 402, the second rail 403, and the third rail 4051 are each of a "T" type structure. The slide 5 has a screw hole 501 on one side and further includes a lock bolt 7 screwed with the screw hole 501 for abutting against the first rail 402 or the second rail 403 or the third rail 4051.

In use, the first rail 402, the second rail 403 and the third rail 4051 are arranged coaxially, and the third rail 4051 is rotatable and dockable between the first rails 402 and the second rail 403. The T-shaped structure is stable, and the slide seat 5 and the guide rail can be locked by the locking bolt 7 for positioning. Of course, the sliding of the sliding seat 5 on the guide rail can also depend on the existing electric technology to realize automation, so that the automatic sliding seat is convenient to adapt to a higher greenhouse. The opening of the ventilation window 9 can be fixed at a lower position, and then the sliding frame 4 slides on the guide rod 1 to adjust the height position. The sliding of the sliding frame 4 on the guide rod 1 can be realized by rolling or releasing the upper film 2 or the lower film 3, and can also realize active control by the existing electric technology, which are all the prior art.

Further, the guide rod 1 moves relative to the greenhouse support, and the guide rod 1 moves to approach or separate from the greenhouse support, so as to provide space for the rotating frame 405 to rotate. The telescopic rod 8 is provided with a movable end 801 and a fixed end 802, wherein the movable end 801 is arranged on the guide rod 1, and the fixed end 802 is fixed relative to the greenhouse bracket.

When the rotary frame 405 rotates in use, the rotary frame can be used for setting up the avoidance space on the greenhouse support to meet the requirement of rotating space, natural movement can be realized by means of follow-up of the guide rod 1, for example, when the rotary frame 405 rotates 90 degrees anticlockwise, the second film winding shaft 602 is close to the greenhouse support, the first film winding shaft 601 is far away from the greenhouse support, at the moment, the sliding frame 4 and the rotary frame 405 are wholly far away from the greenhouse support, the guide rod 1 is far away from, and the telescopic rod 8 is telescopic. The upper membrane 2 is in a relatively taut state and provides a positioning function. In all the adjusting or rotating actions, the film winding shaft can wind or release the upper film 2 or the lower film 3 according to the requirement.

When more telescopic rods 8 are needed, the slip ring 401 can be in a C shape, and the movable end 801 is avoided.

It will be understood that the application has been described in terms of several embodiments, and that various changes and equivalents may be made to these features and embodiments by those skilled in the art without departing from the spirit and scope of the application. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the application without departing from the essential scope thereof.
