The greenhouse can plant plants in seasons unsuitable for plant growth, can prolong the growth period and increase the yield, and is mainly used for cultivating or growing seedlings of plants such as warm vegetables, flowers and trees in low-temperature seasons. It is understood that greenhouses are used primarily for non-seasonal or non-regional plant cultivation, scientific research, additive breeding, ornamental plant cultivation, and the like.

In order to make the temperature in the greenhouse suitable for plant growth at low temperature, the existing greenhouse includes a heat insulation space of the greenhouse, which is disposed in the internal space of the multi-span greenhouse, and is used for heat insulation and energy saving of the multi-span greenhouse, so that the temperature in the greenhouse is kept in a temperature range suitable for plant growth in the greenhouse.

Specifically, the heat insulation space of the existing multi-span greenhouse comprises a first heat insulation assembly arranged horizontally and a second heat insulation assembly arranged vertically. The first heat insulation assembly comprises a first heat insulation structure layer which is transversely arranged at the upper part of the greenhouse space, and when the first heat insulation structure is unfolded, the gas on the upper side and the gas on the lower side of the first heat insulation structure can be prevented from generating convection exchange; a second heat insulation assembly is arranged below the first heat insulation assembly, the second heat insulation assembly forms a ring shape along the inner side below the first heat insulation assembly, the second heat insulation assembly comprises a second heat insulation structure, the lower end of the second heat insulation structure is connected to the ground, the rest parts of the second heat insulation structure can be movably unfolded upwards or folded downwards, and when the second heat insulation structure is unfolded, the convection exchange of gas on the inner side and the outer side of the second heat insulation structure can be prevented;

when the first heat preservation structure transversely expandes and the vertical expansion of second heat preservation structure, second heat preservation structure upper end butt in first heat preservation structure, second heat preservation structure and first heat preservation structure cooperation are along horizontal and vertical formation thermal-insulated space.

The inventors have found that there are two problems with the insulated space of today's greenhouses: firstly, the vertical surfaces of the greenhouse are provided with access doors so that personnel and vehicles can conveniently enter and exit the greenhouse, the second heat insulation structures are required to be disconnected at the access doors of the greenhouse to leave gaps, and the vertical surfaces of the greenhouse where the access doors are located are changed into two second heat insulation structures from the original one, so that on one hand, the integrity and the air tightness of the second heat insulation structures are damaged, and the integral heat insulation effect of a heat insulation space is influenced; on the other hand, only one driving mechanism is needed to drive the second heat-insulating structure to be opened and closed originally, and the two driving mechanisms are correspondingly needed to drive the second heat-insulating structure to be opened and closed correspondingly when the second heat-insulating structure is changed into the two second heat-insulating structures, so that the complexity of opening and closing operation is increased, and the cost of opening and closing operation is increased. Secondly, the second heat preservation structure can be unfolded or folded only by means of the lifting function of the lifting mechanism, the lower part of the lifting mechanism is connected to the ground, the upper end of the lifting mechanism is free, the upper end of the lifting mechanism is connected with the upper end of the second heat preservation structure, when the vertical surface of the greenhouse is high, correspondingly, the height of the second heat preservation structure after being unfolded is also high, the lifting mechanism is required to be lifted to be high, and therefore the lifting mechanism has the danger of falling caused by losing stability, and therefore the use has great limitation.

Based on the consideration, in order to improve the air tightness and the stability of the vertical surface heat insulation structure of the greenhouse, the inventor designs the greenhouse through intensive research, wherein the greenhouse comprises a greenhouse roof heat insulation device and a greenhouse vertical surface heat insulation device; the greenhouse vertical surface heat preservation device comprises a plurality of cantilevers, a first blocking structure, a first folding and unfolding type heat insulation sheet and a first folding mechanism, wherein the cantilevers are arranged on the greenhouse vertical surface structure below the greenhouse roof heat preservation device, the cantilevers are arranged at intervals along the horizontal extending direction of the greenhouse vertical surface structure, the first blocking structure is arranged on the cantilevers, the first folding and unfolding type heat insulation sheet is at least arranged on the cantilevers, the first blocking structure is used for abutting against the greenhouse roof heat preservation device and can be connected to the first folding and unfolding type heat insulation sheet, the first folding and unfolding type heat insulation sheet can be downwards unfolded and extended to the vicinity of the ground or upwards folded and unfolded to the vicinity of the cantilevers under the matching of the cantilevers, and the first blocking structure, the unfolded first folding and unfolding type heat insulation sheet are matched with the greenhouse roof heat preservation device, a heat insulation space structure can be formed in the greenhouse.

The vertical face of the greenhouse can form an access door through the folding and lifting of the first folding and unfolding type heat insulation sheet, the greenhouse vertical face heat insulation device does not need to be disconnected at the access door, and when the access door needs to be used, the first folding and unfolding type heat insulation sheet only needs to be folded and lifted, so that the integrity of the greenhouse vertical face heat insulation device is maintained, and meanwhile, the complexity of the opening and closing operation of the vertical face heat insulation device of the greenhouse is not increased. Due to the arrangement of the cantilever, the opening and closing operation of the greenhouse vertical face heat preservation device is stable even if the greenhouse vertical face is very high, and the possibility of instability of the lifting machine in the prior art due to too high height is overcome.

The function of the cantilever 110 is to make the first folded and unfolded heat insulation sheet 120 in the preset greenhouse vertical surface heat preservation device 1 fully spread the vertical surface space between the cantilever 110 and the ground 4 from top to bottom, and prevent the heat energy of one side of the first folded and unfolded heat insulation sheet 120 from transferring to the other side.

The cantilever 110 may be supported by a single profile or may be formed by combining a plurality of profile sections. One end of the cantilever 110 connected with the greenhouse vertical surface structure 100 is fixed, the other end points to the inner space of the greenhouse 1000, the other end can be a free end, and can also be connected with other functional equipment in the greenhouse 1000, for example, the greenhouse 1000 for livestock and poultry cultivation, and the cantilever 110 can be connected with cultivation equipment; in a greenhouse 1000 for aquaculture, the boom 110 may be attached to the wall of a fish pond.

The four greenhouse facade heat preservation devices 1 and the greenhouse roof heat preservation device 2 in the greenhouse 1000 space are matched and abutted to enclose a new space, but gaps exist between the four greenhouse facade heat preservation devices 1 and the greenhouse roof heat preservation device 2 due to the separation of the cantilever 110. The first blocking structure 160 is arranged, and the first blocking structure 160 is used for blocking and filling the gap, so that the heat energy in the new space can be prevented from transferring to the outside of the space through the gap, and the new space becomes the greenhouse heat insulation space structure 3. In the prior art, since the cantilever 110 is not provided, the upper end of the facade insulation structure can be directly abutted against the roof insulation structure, and therefore, the first blocking structure 160 is not required to be provided in the prior art.

The plurality of cantilevers 110 are arranged near the lower portion of the greenhouse roof insulation device 2 at intervals along the horizontal extending direction of the greenhouse facade structure 100, so as to reduce a gap existing between the upper end of the first folded and unfolded heat insulation sheet 120 and the second folded and unfolded heat insulation sheet 210, and accordingly, the cross section of the first blocking structure 160 can be reduced, and the shading of the first blocking structure 160 to the space of the greenhouse 1000 is reduced.

In the heat preservation state, the upper end of the first sealing structure 160 in the greenhouse vertical heat preservation device 1 abuts against the second folded and unfolded heat insulation sheet 210, so as to prevent the heat energy inside the greenhouse heat insulation space structure 3 from transferring outwards through the gap between the second folded and unfolded heat insulation sheet 210 and the first folded and unfolded heat insulation sheet 120 in the greenhouse vertical heat preservation device 1.

The first sealing structure 160 may be a separate structure, or may be a structure integrated with the first folded and unfolded heat insulating sheet 120 in the greenhouse vertical surface heat insulating device 1. In the integrated structure, the cantilever 110 is connected to the first folded and unfolded heat insulation sheet 120 at a predetermined position above the first folded and unfolded heat insulation sheet 120.

The first blocking structure 160 may be a deformable structure. When the second folded and unfolded heat insulation sheet 210 in the greenhouse roof heat insulation device 2 is the second foldable and unfolded heat insulation sheet 211, the volume of the first blocking structure 160 can be thinned and reduced in the opening and closing operation process of the greenhouse roof heat insulation device 2, so that the opening and closing operation of the second foldable and unfolded heat insulation sheet 211 in the greenhouse roof heat insulation device 2 is not hindered, and as shown in fig. 1, the first blocking structure 160 on the right greenhouse vertical face heat insulation device 1 becomes thinned and reduced, and the folding and folding of the second foldable and unfolded heat insulation sheet 211 in the greenhouse roof heat insulation device 2 above the first blocking structure is not influenced; when the second foldable and unfoldable thermal insulation sheet 211 in the greenhouse roof thermal insulation device 2 is unfolded to be in a thermal insulation state, the first blocking structure 160 becomes thicker and larger, and can squeeze a gap between the upper part of the first foldable and unfoldable thermal insulation sheet 120 in the greenhouse facade thermal insulation device 1 and the second foldable and unfoldable thermal insulation sheet 210 in the greenhouse roof thermal insulation device 2.

The deformable structure may be an inflatable deflating chamber bladder structure 102 that grows in size when inflated and grows in size when deflated. The inflatable deflation cavity bladder structure 102 can be made of an air-tight film material.

Compared with the prior art, the scheme has the advantages that: firstly, the heat preservation devices of the four greenhouse vertical surface structures 100 of the greenhouse 1000 do not need to be disconnected at the access door, and when the access door needs to be used, only the first folding and unfolding type heat insulation sheet needs to be folded and lifted, so that the integrity of the vertical surface heat preservation structure is kept. Secondly, because the cantilever 110 is arranged, the opening and closing operation of the vertical surface heat preservation device 1 is stable even if the vertical surface structure 100 of the greenhouse is very high, and the possibility of instability of a lifting mechanism in the prior art due to too high height is overcome.

When the greenhouse vertical surface heat preservation device 1 is idle, the first bubble film structure 121 can be regularly bound upwards by the retracting rope 140 to be folded and retracted, so that the volume of the first bubble film structure is minimized, and the shading of the first folding and unfolding type heat insulation sheet 120 to the space of the greenhouse 1000 can be reduced.

In some embodiments, multiple layers of the first bubble film structures 121 may be disposed to enhance the heat preservation effect of the greenhouse facade heat preservation apparatus 1, and only one set of the lifting portions 130, one set of the retracting ropes 140, and one set of the first driving mechanism 150 are used to achieve the synchronous retracting or expanding of the multiple layers of the first bubble film structures 121.

The lifting portion 130 may be configured as a box with an open upper portion, and when the first foldable and expandable thermal insulation sheet 120 is completely folded and retracted to the lower portion of the cantilever 110, the first foldable and expandable thermal insulation sheet 120 is completely stored by the box lifting portion 130, so that the first foldable and expandable thermal insulation sheet 120 is protected from the sunlight by the box lifting portion 130 when it is idle in summer.

It should be noted that, different regions have different degrees of coldness in winter, and for colder regions, multiple layers of the first bubble film structures 121 may be disposed, and the upper ends of the foldable and unfoldable first bubble film structures 121 of each layer are connected to the cantilever 110 at intervals, and the lower ends are connected to the lifting portion 130 at intervals.

As shown in fig. 8, in some embodiments, the first folding mechanism further comprises a first roller 180, the first roller 180 is suspended from the lower side of the cantilever 110 and connected to the lower end of the first folded and unfolded heat insulation sheet 120; a cantilever pulley 111 is arranged at a preset position of the cantilever 110; the middle part of the reeling and unreeling rope 140 is sequentially wound around the first reel 180 and the cantilever pulley 111; the first driving mechanism 150 includes a first rotating shaft 151, and the corresponding end of the winding/unwinding rope 140 is fixedly connected to the first rotating shaft 151, and the first rotating shaft 151 is disposed at a predetermined position below the suspension arm 110.

When the first folded and unfolded heat insulation sheet 120 needs to be unfolded, the first rotating shaft 151 is rotated reversely, the first rolling shaft 180 moves downwards along with the sagging of the winding and unwinding rope 140 by self-weight, and the first folded and unfolded heat insulation sheet 120 is synchronously released and unfolded from the first rolling shaft 180.

The middle part of the retracting rope 140 sequentially surrounds the first reel 180 and the cantilever pulley 111, so that the process of retracting or unfolding the first retracting and unfolding type heat insulation sheet 120 by the retracting rope 140 is more stable, and the first retracting and unfolding type heat insulation sheet 120 does not need to have a folding functional structure, so that the structure of the greenhouse vertical surface heat insulation device 1 is simplified.

As shown in fig. 9, in some embodiments, the first folding mechanism further includes a first driving mechanism 150, a second reel 181 and a second reel connector 182, the second reel connector 182 is fixedly connected to the predetermined position of the cantilever 110, the second reel 181 is rotatably connected to the second reel connector 182, the first driving mechanism 150 is drivingly connected to the second reel 181, one end of each of the plurality of first folded and unfolded thermal insulation sheets 120 is sequentially and fixedly connected to the second reel 181 between the adjacent second reel connectors 182, and the rest of the plurality of first folded and unfolded thermal insulation sheets are wound on the corresponding second reel 181 and folded upwards or released from the second reel 181 and unfolded downwards.

It should be noted that the second reel connector 182 may be a coupler, and two ends of two adjacent second reels 181 are connected by the second reel connector 182. The provision of the second spool connector 182 prevents the second spool 181 from being too long to bend, but the first deployment of the thermal insulating sheet 120 wound on the second spool 181 needs to be disconnected at the second spool connector 182 due to the blockage of the second spool connector 182.

The second spool connector 182 may be a structure provided with a closed loop through which the second spool 181 is rotatably attached.

The second reel connector 182 may be a ring structure with a notch provided on an upper portion thereof, from which the second reel 181 is rotatably rested in a ring-shaped configuration.

The first driving mechanism 150 may directly drive the second reel 181, or may drive the second reel 181 through the second reel connector 182. One end of each of the first folding and unfolding heat insulation sheets 120 is sequentially and fixedly connected to the second reel 181 between the adjacent second reel connectors 182, and the rest of the first folding and unfolding heat insulation sheets 120 are wound on the corresponding second reel 181 and folded upwards or released from the second reel 181 and unfolded downwards, so that the folding or unfolding stability of the first folding and unfolding heat insulation sheets 120 can be improved.

In some embodiments, an elongated deskew seal guide 190 is disposed vertically below the second spool connector 182, the deskew seal guide 190 having an upper end attached to the greenhouse facade structure 100 and/or the cantilever 110 near the second spool connector 182, and the lower end of the deskew seal guide 190 attached to the ground 4.

The deviation rectifying sealing guide sheet 190 has two functions, one is a sealing function, which reduces the loss of the internal heat energy of the greenhouse heat insulation space structure 3 from the gap between the side edges of the adjacent first folding and unfolding heat insulation sheet 120 disconnected by the second scroll connector 182; the second is a guiding function, which prevents the first folding and unfolding type heat insulation sheet material 120 from deviating in the unfolding or folding process.

The structure of the deviation-correcting sealing guide sheet 190 can be varied, and in some embodiments, the deviation-correcting sealing guide sheet 190 comprises a double-layer sealing sheet, a dividing connecting wall 191 is disposed in the middle of the double-layer sealing sheet along the longitudinal direction of the double-layer sealing sheet, the dividing connecting wall 191 connects the double-layer sealing sheet into a whole at intervals, so that the intervals between the double-layer sealing sheet form a concave guide groove, and the two sides of the first folded and unfolded heat insulation sheet 120 can be inserted into the concave guide groove to move up and down.

The concave guide groove extends along the folding or unfolding direction 250 of the first folding and unfolding type heat insulation sheet 120, and both sides of the first folding and unfolding type heat insulation sheet 120 are embedded in the concave guide groove and can be folded or unfolded along the extending direction of the concave guide groove under the guidance of the concave guide groove.

The two sides of the first folded and unfolded heat insulation sheet 120 are embedded in the concave guide groove and then generate resistance when moving up and down, and since the first folded and unfolded heat insulation sheet 120 has light weight and may have an unsmooth phenomenon due to self-weight descending in the groove, a counterweight may be disposed at the bottom end of the first folded and unfolded heat insulation sheet 120. As shown in fig. 10-11, in some embodiments, the first folding mechanism includes a first driving mechanism 150 and a third reel 183; a concave receiving and releasing part 192 is arranged at the lower side of the cantilever 110, a third scroll 183 is arranged in the concave receiving and releasing part 192, the upper end of the first folding and unfolding type heat insulation sheet material 120 is fixedly connected to the third scroll 183, the middle part of the first folding and unfolding type heat insulation sheet material 120 is wound on the third scroll 183 and bypasses the upper edge at one side of the concave receiving and releasing part 192, and the lower end of the first folding and unfolding type heat insulation sheet material 120 hangs down freely; the first driving mechanism 150 drives the third reel 183 to rotate, so that the first folded and unfolded thermal insulation sheet 120 is wound and folded on the third reel 183, or is released and unfolded downwards from the third reel 183.

The lifting of the third reel 183 by the concave receiving portion 192 can prevent the third reel 183 from being bent, thereby improving the stability of the first folded and unfolded heat insulating sheet 120 to be folded or unfolded. Therefore, the third reel 183 on one greenhouse vertical structure 100 can be arranged as a whole, and since the first foldable and expandable insulating sheet 120 wound on the third reel 183 is not divided by the concave receiving portion 192, the first foldable and expandable insulating sheet 120 on the inner side of one greenhouse vertical structure 100 can be arranged as a whole. To reduce frictional resistance between the first expanded thermal insulation sheet 120 and the concave storage 192, a roller 193 may be provided in the concave storage 192. To prevent the first folded and deployed insulation sheet 120 from sinking downward between the arms 110, a lever 194 can be provided along the concave storage 192 between the arms 110, and the first folded and deployed insulation sheet 120 can be released from the third reel 183 and deployed vertically downward between the arms 110 by the lever 194, or wound up for storage on the third reel 183 by the lever 194. The support rods 194 act as a stop and guide for the folding and unfolding of the first folded and unfolded thermal insulation sheet 120. To reduce frictional resistance between the bar 194 and the first folded and unfolded thermal insulation sheet 120, a roller 193 may be provided on the bar 194.

A weight may be placed at the downwardly depending bottom end of the first sheet 120 to overcome the problem of sagging less quickly due to lighter weight.

The bottom end of the first blocking structure 160 can abut the first sheet of concertina expanded thermal insulation 120 at the tow 194.

As shown in fig. 12 to 14, in some embodiments, the second blocking structures 170 and the plurality of first folded and unfolded heat insulating sheets 120 are disposed at intervals on the cantilever 110, and the second blocking structures 170 are disposed on both sides of the plurality of first folded and unfolded heat insulating sheets 120 in the horizontal extending direction and slidably connected to the vertical side ends of the first folded and unfolded heat insulating sheets 120.

When the plurality of first folded and unfolded heat insulation sheets 120 of the greenhouse vertical surface heat preservation device 1 are unfolded downwards to be in a heat preservation state, the lower end of the spacing space is abutted to the ground 4 and is blocked by the ground 4, the upper end of the spacing space is blocked by the first blocking structure 160, and the two side ends along the horizontal extension direction are blocked by the second blocking structure 170, so that the air in the spacing space is in a relative static state, and the heat resistance of the air is improved.

There are various ways to drive the second sealing structure 170 to close or unfold, for example, in some embodiments, the second sealing structure 170 includes a fourth reel 171 and a sealing coil, the sealing coil is wound and connected to the fourth reel 171, the fourth reel 171 is connected to the nearby greenhouse facade structure 100 and/or the cantilever 110, and the fourth reel 171 can rotate to close or unfold the sealing coil to realize the closing or unfolding of the second sealing structure 170.

The plugging coiled material is a flexible material with a heat preservation effect. The plugging coiled material of the second plugging structure 170 releases sagging when heat preservation is needed, and plays a plugging role; when the heat preservation is not required, the winding is folded on the fourth reel 171, and the sunlight is not blocked.

Through the rotation of the fourth reel 171, the plugging coiled material is driven to be folded in the daytime so as to reduce the shielding of the plugging coiled material in the greenhouse 1000, or the plugging coiled material is driven to be unfolded at night so as to improve the heat insulation performance of the greenhouse vertical face heat insulation device 1, and the driving mode is simple and the stability is good.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
