[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0039] like Figure 1-Figure 3 As shown, the present invention provides a rolling device, including a rolling unit, the rolling unit including a winding assembly and an unwinding assembly respectively located on both sides of the structure to be rolled, a coiled material layer 9 and a pull rope 8; the winding assembly includes a winding shaft 4, and a first driving device for driving the winding shaft 4 to rotate, the unwinding assembly includes an unwinding shaft 5, and a second driving device for driving the unwinding shaft 5 to rotate; the first end of the pull rope 8 is connected to the winding shaft 4, the second end of the pull rope 8 is connected to the unwinding shaft 5, the first end of the coiled material layer 9 is connected to the pull rope 8, the end of the coiled material layer 9 close to the unwinding shaft 5 is the first end of the coiled material layer 9, and the distance between the first end of the coiled material layer 9 and the unwinding shaft 5 is not less than the distance between the unwinding shaft 5 and the winding shaft 4.
[0040] The present invention respectively arranges an unwinding assembly and a winding assembly on both sides of the structure to be rolled up, the first end of the pull rope 8 is connected to the winding shaft 4, and the second end of the pull rope 8 is connected to the unwinding shaft 5; when the coil layer 9 needs to be rolled up, the first driving device drives the winding shaft 4 to rotate, and the second driving device drives the unwinding shaft 5 to rotate, which makes the pull rope 8 move in the direction of the winding shaft 4. Because the first end of the coil layer 9 is connected to the pull rope 8, the unrolled coil layer 9 will be gradually rolled onto the winding shaft 4 under the drive of the pull rope 8, and the end of the coil layer 9 close to the unwinding shaft 5 is the first end, and the distance between the first end of the coil layer 9 and the unwinding shaft 5 is not less than the distance between the unwinding shaft 5 and the winding shaft 4. The material layer 9 can be completely rolled up onto the winding shaft 4 without blocking the structure to be laid. When the material layer 9 needs to be unfolded, the first driving device drives the winding shaft 4 to rotate in the opposite direction (reverse rotation refers to the reversal of the rotation direction of the winding shaft 4 relative to when the material layer 9 is rolled up), and the second driving device drives the unwinding shaft 5 to rotate in the opposite direction (reverse rotation refers to the reversal of the rotation direction of the unwinding shaft 5 relative to when the material layer 9 is rolled up). This causes the pull rope 8 to move toward the unwinding shaft 5. Since the first end of the material layer 9 is connected to the pull rope 8, the material layer 9 wound on the winding shaft 4 will gradually unfold as the pull rope 8 moves until it covers the area to be laid of the structure to be rolled up.
[0041] It should be noted that the end of the coil layer 9 close to the unwinding shaft 5 is the first end of the coil layer 9, and the end of the coil layer 9 close to the winding shaft 4 is the second end of the coil layer 9. The distance between the first end of the coil layer 9 and the unwinding shaft 5 refers to the length of the pull rope 8 in the area from the first end of the coil layer 9 to the unwinding shaft 5. The coil layer 9 has various types according to the actual working conditions. For example, the coil layer 9 can be a light-shielding layer, an insect-proof layer or a thermal insulation layer. It can also be provided with multiple layers of different types of coil layers 9 according to the actual working conditions. The first driving device and the second driving device can be a rotary driving device such as a rotary motor. The strength and type of the pull rope 8 and the coil layer 9 meet the working conditions. The structure to be rolled can be a greenhouse, a residence, a construction building and other structures. Whether the coil layer 9 is rolled up or unrolled depends on the requirements of the structure to be rolled up. For example, when the structure to be rolled up is a greenhouse and the coil layer 9 is a thermal insulation layer, the coil layer 9 is unrolled and laid on the roof of the structure to be rolled up at night and rolled up during the day.
[0042] Furthermore, the second end of the coiled material layer 9 in the present invention has a variety of configurations. For example, the second end of the coiled material layer 9 may be connected to the reel 4. In this case, because the distance between the first end of the coiled material layer 9 and the unwinding shaft 5 is not less than the distance between the unwinding shaft 5 and the rewinding shaft 4, when the coiled material layer 9 is rolled up, the coiled material layer 9 can be completely rolled up onto the rewinding shaft 4; or, the second end of the coiled material layer 9 may not be connected to the rewinding shaft 4. In this case, the second end of the coiled material layer 9 is connected to the drawstring 8, and the distance between the second end of the coiled material layer 9 and the rewinding shaft 4 is not less than the distance between the rewinding shaft 4 and the unwinding shaft 5. , which allows the material layer 9 to be completely rolled up onto the winding shaft 4 or onto the unwinding shaft 5 when the material layer 9 is rolled up, thereby improving the fault tolerance of the rolling device in the present invention: if the operator accidentally starts the second driving device to roll the material layer 9 toward the unwinding shaft 5, after the operator discovers the problem, there is no need to re-roll the material layer 9 onto the winding shaft 4, and the material layer 9 can continue to be rolled up onto the unwinding shaft 5, thereby making the rolling of the material layer 9 in the present invention more convenient.
[0043] Furthermore, when there is only one group of coiled material layers, the coiled material layers 9 can be arranged inside the structure to be rolled to form an inner roll-up structure, or can be arranged outside the structure to be rolled to form an outer roll-up structure. When there are multiple groups of coiled material layers 9 (multiple groups means more than one group), the coiled material layers 9 can be arranged entirely inside the structure to be rolled, or entirely outside the structure to be rolled, or part of the coiled material layers 9 can be arranged inside the structure to be rolled, and part of the coiled material layers 9 can be arranged outside the structure to be rolled; and when there are multiple groups of coiled material layers 9, no matter the coiled material layers 9 are arranged inside the structure to be rolled and / or outside the structure to be rolled, the coiled material layers 9 are arranged sequentially from the inside to the outside (from the inside to the outside means the direction from the inside of the structure to be rolled toward the outside of the structure to be rolled). And / or, and / or both mean that the preceding text description and the following text description can exist simultaneously or separately. Among them, whether the coiled material layers 9 are arranged in one group or multiple groups, and are arranged only inside or outside the structure to be rolled, or are arranged simultaneously inside and outside the structure to be rolled depends on the actual working conditions. The pull rope 8 matched with each coil layer 9 is set at the same position as the coil layer 9, that is, when the coil layer 9 is outside the structure to be rolled, the pull rope 8 is also outside the structure to be rolled, and when the coil layer 9 is inside the structure to be rolled, the pull rope 8 is also inside the structure to be rolled. The winding assembly and unwinding assembly matched with each coil layer 9 can be arranged with the coil layer 9 or set at other positions, as long as the setting of the winding assembly and unwinding assembly does not affect the normal spreading and winding of the coil layer 9.
[0044] like Figure 1-Figure 2 As shown, in the present invention, multiple groups of coiled material layers 9 are all located inside the structure to be rolled, which forms an inner rolling structure. Compared with the outer rolling structure in which the coiled material layer 9 is only laid outside the structure to be rolled, the inner rolling structure avoids direct contact with the outside, reduces damage to the coiled material layer 9 caused by rain, snow and direct sunlight, and prolongs the service life of the coiled material layer 9.
[0045] When the structure to be rolled is a greenhouse, most of the plants in the greenhouse will not be arranged close to the two sides of the structure to be rolled, so the present invention arranges the winding assembly and the unwinding assembly on both sides close to the structure to be rolled, which makes the winding assembly and the unwinding assembly avoid blocking the plants in the structure to be rolled as much as possible, ensuring that the plants can receive sunlight in all directions; and / or, the winding assembly and the unwinding assembly are both arranged close to the bottom of the structure to be rolled, which reduces the center of gravity of the winding assembly and the unwinding assembly, reduces the risk of shaking or tipping over of the winding assembly and the unwinding assembly during operation, saves the top space of the structure to be rolled, and makes it more convenient to maintain the unwinding assembly and the winding assembly.
[0046] When the setting height of the winding assembly and the setting height of the unwinding assembly are different from the height of the coiled material layer 9 required by the structure to be rolled, a guide assembly for guiding the coiled material layer 9 or the pull rope 8 is provided between the unwinding assembly and the winding assembly. The guide assembly is located on the movement trajectory of the pull rope 8, and the height of the guide assembly is level with the height of the coiled material layer 9 required by the structure to be rolled. The height of the coiled material layer 9 required by the structure to be rolled means that when the coiled material layer 9 is unfolded at this height, the environmental conditions such as temperature and humidity in the structure to be rolled can meet the requirements of the structure to be rolled. The unwinding assembly and the winding assembly can be set at corresponding positions according to the spatial layout in the structure to be rolled, and the guide assembly is used to pull / press the coiled material layer 9 to the height of the coiled material layer 9 required by the structure to be rolled. The guide assembly can specifically be a guide wheel.
[0047] The guide assembly may not be a guide wheel. Figure 1-Figure 3 As shown, at this time, the guide component is a first steel wire 6 fixed on the pull rope 8, the first steel wire 6 is arranged perpendicular to the pull rope 8, the first steel wire 6 is located between the pull rope 8 and the coiled material layer 9, and the second end of the coiled material layer 9 is fixed on the first steel wire 6. The first steel wire 6 supports the coiled material layer 9, and after the coiled material layer 9 is in place (the coiled material is in place means that the coiled material layer 9 is laid in the area where the structure to be laid needs to be laid), it cooperates with the unwinding shaft 5 and the winding shaft 4 to make the coiled material layer 9 in an unfolded state.
[0048] And / or, the roll-laying device further includes a tensioner for adjusting the tension of the drawstring 8; and / or, in the present invention, there are multiple ways of connecting the coiled material layer 9 and the drawstring 8, for example, the second end of the coiled material layer 9 is bonded to the drawstring 8; or, the coiled material layer 9 is welded to the drawstring 8; or, the coiled material layer 9 is clamped to the drawstring 8; or, the coiled material layer 9 is tied to the drawstring 8; or, the coiled material layer 9 is fixed to the drawstring 8 by screws. Among them, the coiled material layer 9 and the drawstring 8 can also use the above multiple ways of connection at the same time, but the way of connection between the coiled material layer 9 and the drawstring 8 is not limited to the above way of connection.
[0049] Preferably, support assemblies are provided on both sides of the structure to be rolled, and the support assemblies include a pair of support members 2 arranged along the length direction of the structure to be rolled, a winding shaft 4 is provided between the two support members 2 located on one side of the structure to be rolled, and the two ends of the winding shaft 4 are respectively connected to the two support members 2, and an unwinding shaft 5 is provided between the two support members 2 located on the other side of the structure to be rolled, and the two ends of the unwinding shaft 5 are respectively connected to the two support members 2; Figure 1-Figure 3 As shown, the support member 2 may be specifically an L-shaped plate, the short side of the L-shaped plate is fixed on the arch frame, and the long side of the L-shaped plate is used to support the unwinding shaft 5 and the winding shaft 4.
[0050] And / or, a plurality of arch rods 1 are sequentially arranged along the length direction of the structure to be rolled, the winding assembly and the unwinding assembly are respectively located on both sides of the arch rod 1, a second steel wire 7 is arranged at the arch shoulder of the arch rod 1, the second steel wire 7 is arranged along the length direction of the structure to be rolled, and a pulley is sleeved on the second steel wire 7, the pulley is slidably matched with the pull rope 8, and the pulley constitutes a guide assembly. The two ends of the second steel wire 7 are respectively connected to the arch shoulder through the steel wire support 3, and the steel wire support 3 can be specifically a connecting plate. And the present invention can sequentially arrange multiple groups of laying devices along the length direction of the structure to be rolled to meet the needs of the structure to be rolled.
[0051] Furthermore, if Figure 1-Figure 3 As shown, the present invention also provides a greenhouse, which includes a rolling device, a temperature greenhouse constituting a structure to be rolled, and a roll-unwinding assembly and a roll-rewinding assembly are respectively located on both sides of the length direction of the greenhouse.
[0052] In addition, when the coiled material layer 9 is a thermal insulation coiled material layer, the present invention further provides a coiling method using a coiling device or a greenhouse, comprising the following steps:
[0053] Step S1, measuring the soil area A in the structure to be rolled s , and measure the soil heat flux f in the structure to be rolled s , the internal temperature of the structure to be rolled is T in And the external temperature T of the structure to be rolled out , and according to U i =f s ×A s / (T in -T out ) Calculate the roof heat transfer coefficient U i ;
[0054] i is 1, 2, 3...n, 12, 13, 23...1n...123...n, which respectively represent unfolding only the first coiled material layer 9, unfolding only the second coiled material layer 9, unfolding only the third coiled material layer 9...unfolding only the nth coiled material layer 9, unfolding the first coiled material layer 9 and the second coiled material layer 9, unfolding the first coiled material layer 9 and the third coiled material layer 9, unfolding the second coiled material layer 9 and the third coiled material layer 9...unfolding the first and nth coiled material layers 9, unfolding all coiled material layers 9;
[0055] Step S2, determine the lowest temperature T outside the structure to be rolled out，min , calculate T as follows in ;
[0056] T in =(T sc ×h t ×A s -T out，min ×U i ) / (ht ×A s +U i )

[0059] Step S3, according to the required temperature inside the roll structure and T in , determine and open the corresponding coil layer 9; the specific operation is as follows, when the roof heat transfer coefficient U when i is 1, 2, 3...n, 12, 13, 23..1n...123...n is obtained according to step S1 and step S2 i , the lowest external temperature of the structure to be rolled is T out，min , the internal temperature of the structure to be rolled is T in Then, the internal temperature of the structure to be rolled is set to T in = The required temperature inside the roll structure. At this time, the U i Substitute T in =(T sc ×h t ×A s -T out，min ×U i ) / (h t ×A s +U i ) until T under this i value in = the required temperature inside the structure to be rolled, and the corresponding coil layer 9 is opened according to the i value at this time.
