The roof space of the multi-span greenhouse needs to be sealed by heat insulation materials for heat insulation at night in winter and sealed by sun shading materials for cooling at daytime in summer. When the multi-span greenhouse building is large in scale, the area of the expanded heat-insulating material or the expanded shading material required for plugging the roof space is large, the volume of the folded heat-insulating material or the folded shading material is large, and accordingly the multi-span greenhouse building is very heavy.

The heat-insulating material and the shading material have large volume and heavy weight, and the operation difficulty is high in the process of overhead lifting installation, maintenance and replacement in the interior below the roof of the multi-span greenhouse. And secondly, when a whole block of heat insulation material or shading material is specifically applied in the air below the multi-span greenhouse roof, the heat insulation material or the shading material needs to be synchronously unfolded for heat insulation or shading or synchronously folded for lighting, and the synchronous operation needs to be correspondingly driven by driving equipment with large power and large size in a centralized manner, so that the realization difficulty is high.

Based on the above, the application provides a roll box module sealing device for sealing a roof space of a multi-span greenhouse, which comprises a plurality of roll box modules, a telescopic end sealing structure, a side end sealing structure, an unfolding driving assembly, a folding driving assembly and a supporting cable; the telescopic end blocking structure is used for blocking a gap between two adjacent rolling box modules in a first direction; in the second direction, the roll box modules and the side end plugging structures are alternately arranged, the side end plugging structures are used for plugging gaps between two adjacent roll box modules in the second direction, and the unfolding driving assembly, the folding driving assembly and the supporting cable are matched, so that the coiled materials can be unfolded or folded on the supporting cable along the first direction and used for closing or unsealing the roof space between the beam column structures.

The rolling box modules are multiple, namely, the whole of large-area, large-volume and heavy-weight heat insulation materials or shading materials are broken into parts to be set into the rolling box modules, and the heat insulation materials or shading materials contained in each rolling box module are small in area, small in size and light in weight, so that the rolling box modules are convenient to lift, install, maintain and replace in the air in the lower part of the roof of the multi-span greenhouse. And each rolling box module is correspondingly matched with the opening and closing driving equipment with small power and small size for dispersed driving, so that the realization difficulty is low. Because the telescopic plugging structure and the side end plugging structure are correspondingly arranged, the problem of gaps existing after small heat-insulating materials or shading materials are assembled is solved, and the sealing effect of one integral installation in the prior art is achieved.

As shown in fig. 1 and 2, the roll box module closing device includes a roll box module 100, a telescopic end blocking structure 200, a side end blocking structure 300, an unfolding driving assembly 400, a folding driving assembly 500 and a supporting cable 600; the roll-box modules 100 include a plurality of the roll-box modules 100 arranged in a row in a first direction 1 and a second direction 2 between beam-column structures 700 of the multi-span greenhouse; in the first direction 1, the roll box modules 100 and the telescopic end blocking structures 200 are alternately arranged, and the telescopic end blocking structures 200 are used for blocking gaps between two adjacent roll box modules 100 in the first direction 1; in the second direction 2, the roll box modules 100 are alternately arranged with the side end blocking structures 300, and the side end blocking structures 300 are used for blocking gaps between two adjacent roll box modules 100 in the second direction 2; the roll-box module 100 and the telescoping end plugging structure 200 are connected to the beam-column structure 700; the roll-box module 100 comprises a roll material 110, a roll 120 and a roll bracket assembly 130, wherein the roll 120 is arranged on the roll bracket assembly 130, the roll material 110 comprises a roll material unfolding end 111, a roll material folding end 112 and two roll material side ends 113, the roll material folding end 112 is wound on the roll 120, and the roll material unfolding end 111 is connected to the unfolding driving assembly 400 according to a preset scheme; one side of the telescopic end blocking structure 200 abuts against the coiled material folding end 112, and the other side of the telescopic end blocking structure is used for contacting with the uncoiled coiled material uncoiling end 111; the side end blocking structure 300 is positioned at one side of the coil folding end 112 and is connected to the beam-column structure 700 and/or the reel bracket assembly 130 according to the preset scheme, the other side of the side end blocking structure is connected to the beam-column structure 700, and the side end blocking structure 300 can be movably abutted against two adjacent coil side ends 113; the retracting drive assembly 500 is disposed near the end of the spool 120 and is in driving connection with the spool 120; one end of the supporting cable 600 is connected to the beam-column structure 700 corresponding to the coil unfolding end 111, and the other end is connected to the beam-column structure 700 corresponding to the reel carriage assembly 130 and/or the coil folding end 112, and the coil box module 100, the unfolding driving assembly 400, and the folding driving assembly 500 are matched with the supporting cable 600, so that the coil 110 can be unfolded or folded on the supporting cable 600 along the first direction 1, and the supporting cable is used for closing or unsealing the roof space 701 between the beam-column structures 700.

It should be noted that the beam-column structure 700 of the multi-span greenhouse refers to the vertical column 709 and/or the beam structure for directly or indirectly supporting the roof structure 702 of the multi-span greenhouse, and the beam structure may be the truss beam 706 or a single section beam.

Preferably, in the present application, the extending direction of the beam structure connected to the middle column 709 is defined as the second direction 2, and the direction perpendicular to the second direction 2 is defined as the first direction 1, then, in the first direction 1, the roll-box modules 100 and the telescopic end blocking structures 200 are alternately arranged, the telescopic end blocking structures 200 are used for blocking the gap between the adjacent roll-box modules 100 in the first direction 1, that is, the telescopic end blocking structures 200 are arranged on the beam-column structure 700 corresponding to the roll-material opening end 111 of the roll-box module 100 and the beam-column structure 700 corresponding to the contraction end, that is, the roll-carrier assembly 130 and/or the roll material 110 wound on the roll 120. Due to the obstruction of the beam column structure 700, two adjacent roll-box modules 100 can only be arranged at two sides of the beam column structure 700, and one roll-box module 100 can only be limited between the inner sides of two adjacent rows of beam column structures 700, so that, because the beam column structure 700 has a thickness, a gap exists between the roll-box modules 100 at two sides of the beam column structure 700, and the gap is a space formed by the thickness of the beam column structure 700, and the telescopic end blocking structure 200 is used for filling the space, and the telescopic end blocking structure 200 is connected to the beam column structure 700, preferably, connected to the beam column structure body, and blocks the space formed by the thickness of the beam column structure 700. In the second direction 2, the roll-box modules 100 are arranged alternately with side-end blocking structures 300, the side-end blocking structures 300 being used to block a gap between adjacent roll-box modules 100, i.e., a gap between adjacent web-side ends 113 of the unwound web 110, in the second direction 2.

The multi-span greenhouse may be provided with bidirectional truss girders 706, the truss girders 706 in both directions being perpendicular to each other. If a truss girder 706 in one direction is disposed above a truss girder 706 in another direction, the roll-to-roll module enclosure provided by the present application may be disposed on either the upper truss girder 706 or the lower truss girder 706. If the end plugging structure 200 is arranged on the lower truss girder 706, the extending direction of the lower truss girder 706 is defined as the second direction 2, the coil box module 100 is arranged on the lower truss girder 706, and the end plugging structure 200 is connected to the lower truss girder 706.

In particular practice, the first direction and the second direction may have further definitions, such as: the multi-span greenhouse can be provided with the bidirectional truss girder 706, the bidirectional truss girder 706 is arranged on the same layer, the truss girder 706 extending in the first direction 1 and the truss girder 706 extending in the second direction 2 intersect to form a rectangular frame, then, in the second direction 2, the truss girder 706 dividing the side end of the adjacent coil 110 exists, the adjacent coil box module 100 forms a gap in the second direction 2, and the side end plugging structure 300 can also be used for plugging the gap.

For a multi-span greenhouse in which the bidirectional truss girder 706 is disposed and the bidirectional truss girder 706 is disposed at the same level, the first direction 1 and the second direction 2 may be arbitrarily defined on the horizontal row of columns or the vertical row of columns below the truss girder 706.

When there is no obstruction of the web 110 side ends of the adjacent roll cassette modules 100 by the beam column structure 700, the side end blocking structure 300 may be provided with the partition wall 330, and the adjacent web 110 side ends slide independently of each other due to the presence of the partition wall 330 without interfering with each other.

For the beam column structure 700 provided with the truss girder 706, the roll-box module 100, the telescopic end plugging structure 200, the side end plugging structure 300, the folding driving assembly 500, and the preset end of the supporting cable 600 are all connected to the preset position of the truss girder 706.

In a specific application, the length of the roll-box module 100 in the second direction 2 is identical to the length of the truss girder 706, and may be integrated with the truss girder 706. For example, if the truss girder 706 has a length of 12 meters, the adjacent truss girders 706 are spaced apart by 10 meters, the coil cassette module 100 has a length of approximately 12 meters, the coil unwinding end 111 can extend by about 10 meters, and the coil side end 113 is spaced apart by approximately 12 meters. When the multi-span greenhouse structure is installed, the rolling box module 100 and the corresponding truss girder 706 can be installed synchronously, and when the multi-span greenhouse structure is installed and the transparent enclosure structure is installed, the telescopic end plugging structure 200, the side end plugging structure 300, the unfolding driving assembly 400, the folding driving assembly 500 and the supporting cable 600 can be installed. When a plurality of layers of the roll box modules 100 are required to be arranged, the roll box modules 100 are arranged at different heights of the truss girder 706 at intervals, and when the coils 110 are fully unfolded and abut against the corresponding telescopic end plugging structures 200, the telescopic end plugging structures 200 can seal the spacing spaces between the coils 110 in the first direction 1.

The driving connection is a power transmission connection and comprises a chain connection, a gear connection, a transmission shaft connection and the like.

The supporting cable 600 is mainly used for supporting the uncoiled coiled material 110, and can also be used for simultaneously supporting the uncoiled coiled material 110, the coiled material 110 wound on the reel 120 and the reel 120, the coiled material 110 is slidably laid on the supporting cable 600, the coiled material 110 is fully uncoiled, and the uncoiled end 111 of the coiled material reaches the corresponding beam-column structure 700 or abuts against the telescopic end blocking structure 200 on the beam-column structure 700.

The coiled material 110 wound on the reel 120 can be unwound by rotating clockwise with the reel 120 and wound up by rotating counterclockwise with the reel 120; the unwinding can also be released along with the counterclockwise rotation of the winding shaft 120, and the winding and folding can also be realized along with the clockwise rotation of the winding shaft 120. In a side view, the support cable 600 is attached to the spool carriage assembly 130 at one end of the coil-receiving end 112 when the coil 110 wound on the spool 120 is unwound as the spool 120 rotates clockwise and wound-up as the spool 120 rotates counterclockwise. The coil 110 wound on the spool 120 is unwound as the spool 120 rotates counterclockwise and the stay 600 is attached to the spool carriage assembly 130 and/or the beam column structure 700 at one end of the coil unwinding end 112 as the spool 120 rotates clockwise to wind up and wind up.

The stay cord 600 may be configured with a drainage slope 610 at the coil receiving end 112 higher than the coil opening end 111 so that the uncoiled coil 110 forms a slope with the stay cord 600 along which dew may be organized to drain away from the upper surface of the coil 110 when it drips from the multi-span greenhouse roof enclosure.

When the web deployment end 111 has a structure that hinders the exposure, the exposure holes 114 may be provided on the web 110 near the web deployment end 111 for organized exposure.

The roll 110 for heat insulation may be a foamed sheet with closed cells. The web 110 for shading may be a translucent fabric or fabric resin composite.

The plurality of rolling box modules 100 are equivalent to a plurality of rolling box modules 100 formed by dividing the whole of large-area, large-volume and heavy-weight heat insulation materials or shading materials into parts, and each rolling box module 100 contains the heat insulation materials or shading materials with small area, small volume and light weight, so that the rolling box modules are convenient to lift, install, maintain and replace in the air in the lower part of the roof of the multi-span greenhouse.
