As shown in fig. 1 and fig. 2, the two figures respectively show the fitting relationship between the plugging sheet 100 and the first plugging airbag 210 when the plugging device 2000 for a greenhouse internal space provided by the present invention is in the plugging state and the decapsulated state, and the fitting relationship has a chronological order, that is, when the plugging sheet 100 is subjected to the folding or unfolding operation, the first plugging airbag 210 needs to be in the deflation state, so that the plugging sheet 100 can be folded or unfolded without hindrance; after the plugging sheets 100 are unfolded, the first plugging air bag 210 needs to be inflated to abut against the plugging sheets 100 on the two sides, and the first plugging air bag are matched to perform a tight plugging function on a preset space part of the greenhouse.
The invention provides a plugging device 2000 for the inner space of a greenhouse, which replaces the original plugging structure in the prior art by using a plurality of foldable and expandable plugging sheets 100 which are arranged at intervals in sequence and a plurality of inflatable and deflatable strip-shaped first plugging air bags 210 which are arranged between two adjacent plugging sheets 100. The advantages are that each plugging sheet 100 has a small area, a small volume and a light weight, the difficulty of installation and construction is less than that of one plugging structure originally used in the prior art, and when a problem occurs in an individual plugging sheet 100, only the plugging sheet 100 with the problem needs to be replaced, unlike the prior art in which a problem occurs in a part of one plugging structure originally used, the whole plugging structure needs to be replaced, thereby reducing the maintenance cost. When the plugging sheet 100 is used specifically, firstly, the fixed end 101 and the movable end 102 are arranged on the plugging sheet 100, the movable end 102 can be unfolded along the unfolding direction 103 to gradually get away from the fixed end 101, then the first plugging air bag 210 is inflated, and the bag wall of the first plugging air bag extends along the inflation direction 201 to abut against the opposite side edge of the plugging sheet 100, so that the plugging purpose is realized. When the specific use that needs to relieve the blockage is needed, the first blocking airbag 210 deflates outwards, the wall thereof deflates inwards and becomes soft, and the first blocking airbag is far away from the opposite side edge of the blocking sheet 100 along the deflation and contraction direction 202, at this time, the movable end 102 of the blocking sheet 100 can be folded along the folding and folding direction 104 without obstacles and gradually approaches the fixed end 101, so as to achieve the purpose of relieving the blockage.
Can set up on the bag wall of first shutoff gasbag 210 towards the mechanism of disappearing and aerify or lose heart by oneself, first shutoff gasbag 210 from dashing of taking lets out mechanism can realize inwards aerifing or the function of outwards bleeding including two-way air pump, can be from taking the two-way air pump of battery drive, the battery of taking can be rechargeable battery, like this, can set up near first shutoff gasbag 210 and charge the office and charge for rechargeable battery, can set up photovoltaic power plant near first shutoff gasbag 210, provide the power for charging office. In the specific application, the length of the plugging sheet 100 is within 12 meters, the distance between the adjacent plugging sheets 100 is 3-5 cm, the length of the first plugging air bag 210 is within 12 meters, the first plugging air bag is arranged within 3-5 cm, the first plugging air bag becomes a transverse air column with the outer diameter of 3-5 cm and the length of 12 meters after inflation and expansion, and the bag wall can be abutted to the plugging sheets 100 on the two sides of the bag wall. In this way, the volume of the first blocking airbag 210 is about 0.0085 cube to 0.024 cube, and in a specific application, the first blocking airbag 210 can complete inflation or deflation within 30 minutes, so that the self-contained inflation and deflation mechanism can be matched accordingly.
The first blocking airbag 210 can also realize inflation and deflation functions through air pipe connection by using an external bidirectional air pump.
The plugging sheet 100 and the first plugging balloon 210 shown in fig. 1 and 2 are used for a plugging device 2000 for composing an inner space of a greenhouse, the plugging device 2000 comprising a greenhouse body 1000, a plurality of plugging sheets 100, a plurality of first plugging balloons 210, a suspension structure 300, and a driving mechanism 500; the occluding sheet 100 is foldable and expandable; a plurality of first blocking balloons 210 are arranged at intervals between the respective blocking sheets 100, the first blocking balloons 210 being inflatable and deflatable, the first blocking balloons 210 being elongated; the suspension structure 300 sequentially and alternately arranges a plurality of plugging sheets 100 at preset positions in the inner space of the greenhouse body 1000, and arranges a first plugging air bag 210 in a gap between two adjacent plugging sheets 100; the driving mechanism 500 is used for driving the plugging sheet 100 to unfold or fold; the inflation or deflation operation of the first plugging air bag 210 is coordinated with the folding or unfolding operation of the plugging sheet 100, so that the driving mechanism 500 can unfold the plugging sheet 100 without hindrance for plugging the preset position of the inner space of the greenhouse body 1000, or fold and unfold without hindrance for releasing the plugging.
It should be noted that the plugging device 2000 for the internal space of the greenhouse provided by the present invention is mainly used for blocking the heat energy in the greenhouse body 1000 from transferring inside and outside the plugging device 2000, so as to create a new space with a preset temperature environment, i.e. the heat insulation space 600, in the greenhouse body 1000.
In the plugging device 2000 for the inner space of the greenhouse provided by the embodiment of the present application, a whole plugging structure originally used in the related art is modified into a combination body which is provided with a plurality of spacing, is foldable and expandable, and is formed by a plurality of plugging sheets 100 and a plurality of inflatable and deflatable strip-shaped first plugging airbags 210 which are arranged in the spacing gaps between the plugging sheets 100, and the driving mechanism 500 is directly or indirectly acted by means of the cooperation of the structure of the greenhouse body 1000. The first plugging air bag 210 is arranged in a gap between the two adjacent plugging sheets 100, the first plugging air bag 210 abuts against the plugging sheets 100 after being inflated, and the first plugging air bag and the second plugging air bag are matched for use, so that the plugging effect of an originally used whole plugging structure is achieved. The driving mechanism 500 can unfold the plugging sheet 100 to perform plugging or fold the plugging sheet to release the plugging. Namely, when the plugging function needs to be exerted, the plugging sheets 100 are unfolded, the first plugging air bag 210 is inflated, the volume is increased, the air bag wall extends to contact and abuts against the side edge of the corresponding plugging sheet 100, the gap between two adjacent plugging sheets 100 is eliminated, and the plugging sheet 100 and the first plugging air bag 210 cooperate to achieve the purpose of tight plugging; when plugging is not needed, the first plugging air bag 210 firstly releases air, so that the volume is reduced, shielding is reduced, and the first plugging air bag is far away from the plugging sheet 100; then, the plugging sheet 100 is folded without being obstructed by the first plugging airbag 210, so that the volume is reduced and the blocking is reduced. Each plugging sheet 100 is a plugging module, and when plugging is required, each first plugging air bag 210 can tightly fill gaps between the plugging modules. In summary, the present invention provides a solution that a plurality of modular structures are used to partially block the preset portions of the greenhouse body 1000 in sequence in the internal space of the greenhouse body 1000 until all the portions are blocked.
The plugging sheet 100 at least comprises a structure capable of slowing down or preventing heat energy from penetrating, and can be various single-material structures and film-coated structures thereof, including a plastic resin closed pore-shaped foaming sheet formed by (film-coated) chemical foaming and physical foaming, a bubble-shaped sheet formed by (film-coated) vacuum forming, and an air column-shaped sheet formed by compounding double-layer films; the composite material structure can also be a composite material structure, which comprises a composite structure formed by a double-layer film material structure and a sandwiched floccule structure, wherein the sandwiching process comprises a sewing process and a heat sealing process.
The gap is formed between the adjacent plugging sheets 100, so as to reduce the deformation of the unfolding or folding caused by the contact friction between the two when the unfolding or folding operations are asynchronous.
The first blocking airbag 210 may be an air column structure with an internal cavity communicated with one another, or a bead-shaped air column structure formed by connecting a plurality of cavity structures in series. The inflated cross section of the first plugging balloon 210 matches the profile of the plugging sheet 100 in the thickness direction after deployment, so that the balloon wall of each part completely abuts against the side edge of all corresponding parts of the plugging sheet 100.
When the plugging sheets 100 are unfolded, the first plugging air bag 210 is inflated and expanded and abuts against the edges of the plugging sheets 100 on the two sides, and gaps between the adjacent plugging sheets 100 are eliminated; when the folding operation of the plugging sheet 100 is to be completed, the first plugging airbag 210 is deflated to reduce its volume and is separated from the plugging sheet 100, and then is folded without hindrance.
Advantages include at least two: firstly, each plugging sheet 100 has a small area, a small volume, a small weight and a small corresponding installation difficulty; secondly, when a local structure of an individual plugging sheet 100 is in trouble, other plugging sheets 100 adjacent to each other on the left and right are not required to be disassembled, and the maintenance cost is low.
The plugging device 2000 for the inner space of the greenhouse is characterized in that a plurality of foldable and expandable plugging sheets 100 and a plurality of inflatable and deflatable first plugging airbags 210 are used in cooperation in turn and alternately to meet the plugging requirement, the whole original whole-sheet-shaped plugging structure is broken into parts and changed into a plurality of foldable and expandable plugging sheets 100 and inflatable and deflatable first plugging airbags 210, each foldable and expandable plugging sheet 100 and each inflatable and deflatable first plugging airbag 210 are small in size and light in weight, and are simple and convenient to manufacture, transport, store, install and maintain, and only individual problematic foldable and expandable plugging sheets 100 and inflatable and deflatable plugging airbags 200 need to be replaced when problems occur locally, so that the use and maintenance cost is correspondingly greatly reduced.

The greenhouse body 1000 may be a multi-span greenhouse or a single-span greenhouse. The column structures 1110 and/or the beam structures 1200 in the first suspension structure 310 are used to support the roof structure of the greenhouse body 1000. According to different types of the greenhouse body 1000, the supporting roof structures can be all column structures 1110, all beam structures 1200, or column structures 1110+ beam structures 1200.

For a multi-span greenhouse, the column structure 1110 includes a vertical stress structure for supporting a roof structure, which may be a vertical column directly supporting the roof structure, or a vertical web member 1202 vertically disposed in a truss structure 1201 in a roof truss structure connected to the vertical column.
For the roof truss structure of the arch truss module 1400 in the multi-span greenhouse, which is formed by combining the arch truss structure and the truss structure 1201 into a whole, it is preferable that the supporting cables 311 are correspondingly connected to the vertical web members 1202 of the truss portions of the arch truss module 1400, accordingly, one end of the first blocking sheet 110 is connected to the vertical web members 1202 of the truss portion on one side of the truss portions of the two truss portions of the arch truss module 1400, and two ends of the first blocking bladder 210 directly or indirectly abut against the vertical web members 1202 of the truss portions on two sides of the arch truss module 1400.

In order to prevent the wind from blowing the unfolded vertical face rolled film, a flexible linear film pressing rope is arranged on the vertical face, and the vertical face rolled film is arranged between the film pressing rope and a column structure of a vertical face structure.
According to the scheme, the hard wind-resistant vertical rod 1500 is used for replacing a film pressing rope, and the phenomenon that the vertical surface film 1120 bulges outwards due to the fact that negative wind pressure can be relieved under the condition that the body of the wind-resistant vertical rod 1500 is not bent outwards is avoided.

If the vertical face rolled film 1120 is still separated from the wind-resistant vertical bar 1500 after being fully unfolded for the purpose of sealing and heat preservation of the wind-resistant energy-saving multi-span greenhouse 1002, the vertical face rolled film 1120 inevitably swings frequently between the wind-resistant vertical bar 1500 and the column structure 1110 of the vertical face structure 1100 when wind blows, which is not favorable for sealing and heat preservation, and the vertical face rolled film 1120 is damaged.
