[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0029] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0030] As Figures 1 - 3As shown in the figure, the present utility model provides a coiling and unrolling device, which includes a coiling and unrolling unit. The coiling and unrolling unit includes a winding assembly and an unwinding assembly respectively located on both sides of the structure to be coiled and unrolled, a coil layer 9, and a pulling 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 pulling rope 8 is connected to the winding shaft 4, the second end of the pulling rope 8 is connected to the unwinding shaft 5, the first end of the coil layer 9 is connected to the pulling rope 8, the second end of the coil layer 9 is connected to the winding shaft 4, and the distance from the first end of the coil layer 9 to the unwinding shaft 5 is not less than the distance between the unwinding shaft 5 and the winding shaft 4.

[0031] In the present utility model, an unwinding assembly and a winding assembly are respectively arranged on both sides of the structure to be coiled and unrolled. The first end of the pulling rope 8 is connected to the winding shaft 4, and the second end of the pulling rope 8 is connected to the unwinding shaft 5. When it is necessary to wind up the coil layer 9, the first driving device drives the winding shaft 4 to rotate, and the second driving device drives the unwinding shaft 5 to rotate. This causes the pulling rope 8 to move in the direction of the winding shaft 4. Since the first end of the coil layer 9 is connected to the pulling rope 8 and the second end of the coil layer 9 is connected to the winding shaft 4, the unfolded coil layer 9 will be gradually wound onto the winding shaft 4 under the drive of the pulling rope 8, and the distance from the first end of the coil layer 9 to the unwinding shaft 5 is not less than the distance between the unwinding shaft 5 and the winding shaft 4. This enables the coil layer 9 to be completely wound onto the winding shaft 4 without blocking the structure to be laid. When it is necessary to unfold the coil layer 9, the first driving device drives the winding shaft 4 to rotate in the reverse direction (the reverse rotation means the reverse rotation relative to the rotation direction of the winding shaft 4 when the coil layer 9 is wound), and the second driving device drives the unwinding shaft 5 to rotate in the reverse direction (the reverse rotation means the reverse rotation relative to the rotation direction of the unwinding shaft 5 when the coil layer 9 is wound). This causes the pulling rope 8 to move in the direction of the unwinding shaft 5, and since the first end of the coil layer 9 is connected to the pulling rope 8, the coil layer 9 wound on the winding shaft 4 will gradually unfold as the pulling rope 8 moves until it covers the area to be laid of the structure to be coiled and unrolled.

[0032] 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 heat-insulating layer, and multiple layers of different types of coil layers 9 can also be set according to the actual working conditions. The first driving device and the second driving device can specifically be rotary driving devices such as rotary motors. The strength and type of the pulling rope 8 and the coil layer 9 both meet the requirements of the working conditions. The structure to be coiled and unrolled can specifically be structures such as greenhouse greenhouses, residences, and construction buildings. Whether the coil layer 9 is wound or unfolded depends on the requirements of the structure to be coiled and unrolled. For example, when the structure to be coiled and unrolled is a greenhouse greenhouse and the coil layer 9 is a heat-insulating layer, the coil layer 9 is unfolded and laid on the roof of the structure to be coiled and unrolled at night and wound up during the day.

[0033] Moreover, when there is only one set of coil layers, the coil layer 9 can be either arranged inside the structure to be coiled, forming an inner coiled structure, or arranged outside the structure to be coiled, forming an outer coiled structure. When there are multiple sets of coil layers (multiple sets means more than one set), all the coil layers 9 can be arranged inside the structure to be coiled, or all arranged outside the structure to be coiled, or some of the coil layers 9 can be arranged inside the structure to be coiled and some outside the structure to be coiled; and when there are multiple sets of coil layers 9, regardless of whether the coil layers 9 are arranged inside and / or outside the structure to be coiled, the coil layers 9 are arranged in sequence from inside to outside (from inside to outside means the direction from the inside of the structure to be coiled towards the outside of the structure to be coiled). And / or, both "and" and "or" mean that the previous and the following textual descriptions can either exist simultaneously or separately. Among them, whether to set one set or multiple sets of coil layers 9, and whether to set them only inside or outside the structure to be coiled, or both inside and outside the structure to be coiled simultaneously, depends on the actual working conditions. The pulling ropes 8 cooperating with each coil layer 9 are in the same position as the coil layer 9, that is, when the coil layer 9 is outside the structure to be coiled, the pulling rope 8 is also outside the structure to be coiled, and when the coil layer 9 is inside the structure to be coiled, the pulling rope 8 is also inside the structure to be coiled. And the winding components and unwinding components cooperating with each coil layer 9 can either be arranged along with the coil layer 9 or be arranged at other positions, as long as the arrangements of the winding components and unwinding components do not affect the normal spreading and winding of the coil layer 9.

[0034] As Figures 1 - 2 shown, in the present utility model, multiple sets of coil layers 9 are all located inside the structure to be coiled, which forms an inner coiled structure. Compared with the outer coiled structure where the coil layer 9 is only laid outside the structure to be coiled, the inner coiled structure avoids direct contact with the outside world, reduces the damage to the coil layer 9 caused by external rain, snow and direct sunlight, and prolongs the service life of the coil layer 9.

[0035] When the structure to be coiled is a greenhouse, most of the plants in the greenhouse are not arranged close to both sides of the structure to be coiled. Therefore, in the present utility model, the winding component and the unwinding component are respectively arranged close to both sides of the structure to be coiled, which makes the winding component and the unwinding component avoid blocking the plants inside the structure to be coiled as much as possible, ensuring that the plants can receive sunlight omnidirectionally; and / or, both the winding component and the unwinding component are arranged close to the bottom of the structure to be coiled, which reduces the center of gravity of the winding component and the unwinding component, reduces the risk of shaking or toppling of the winding component and the unwinding component during operation, saves the top space of the structure to be coiled, and makes it more convenient to maintain the unwinding component and the winding component.

[0036] 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.

[0037] The guide assembly may not be a guide wheel. Figures 1 - 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.

[0038] 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 connecting the coiled material layer 9 and the drawstring 8 is not limited to the above ways of connection.

[0039] 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; Figures 1 - 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.

[0040] Moreover, or, a plurality of arch bars 1 are sequentially arranged along the length direction of the structure to be coiled. The winding assembly and the unwinding assembly are respectively located on both sides of the arch bar 1. A second steel wire 7 is provided at the arch shoulder of the arch bar 1. The second steel wire 7 is arranged along the length direction of the structure to be coiled, and a pulley is sleeved on the second steel wire 7. The pulley is slidably matched with a pulling rope 8, and the pulley constitutes a guiding assembly. Both ends of the second steel wire 7 are respectively connected to the arch shoulder through a steel wire support 3, and the steel wire support 3 can specifically be a connecting plate. Moreover, a plurality of sets of laying devices can be sequentially arranged along the length direction of the structure to be coiled in the present utility model to meet the requirements of the structure to be coiled.

[0041] Furthermore, as Figures 1 - 3 shown, the present utility model further provides a greenhouse. The greenhouse includes a coiling device. The greenhouse constitutes the structure to be coiled. The unwinding assembly and the winding assembly are respectively located on both sides of the length direction of the greenhouse.

[0042] In addition, when the coiled material layer 9 is a heat-insulating coiled material layer, the present utility model further provides a coiling method for applying the coiling device or the greenhouse, including the following steps:

[0043] Step S1, measure the soil area A s inside the structure to be coiled, and measure the soil heat flux f s inside the structure to be coiled, the internal air temperature T in of the structure to be coiled and the external air temperature T out of the structure to be coiled, and calculate the roof heat transfer coefficient U i according to U s = f s × A in / (T out - T i );

[0044] i is 1, 2, 3... n, 12, 13, 23..1n...123...n, respectively representing only unfolding the first layer of the coiled material layer 9, only unfolding the second layer of the coiled material layer 9, only unfolding the third layer of the coiled material layer 9... only unfolding the nth layer of the coiled material layer 9, unfolding the first layer of the coiled material layer 9 and the second layer of the coiled material layer 9, unfolding the first layer of the coiled material layer 9 and the third layer of the coiled material layer 9, unfolding the second layer of the coiled material layer 9 and the third layer of the coiled material layer 9... unfolding the first layer and the nth layer of the coiled material layer 9, unfolding all the coiled material layers 9;

[0045] Step S2, determine the lowest external air temperature T out，min of the structure to be coiled, and calculate T in respectively according to the following formula;

[0046] T in = (T sc × h t × A s - T out，min × U i) / (h t ×A s +U i )

[0047] h t =λ s / d sc +1 / h in ;

[0048] In the formula, T sc is the constant temperature inside the soil; d sc is the depth when the soil temperature is T sc ; λ s is the soil thermal conductivity (W / (m·K)), and h in is the total heat transfer coefficient of the soil surface;

[0049] Step S3, determine and open the corresponding coil layer 9 according to the required temperature inside the structure to be paved and T in . The specific operation is as follows. When the roof heat transfer coefficient U i at i = 1, 2, 3...n, 12, 13, 23..1n...123...n is obtained according to Steps S1 and S2, the lowest outside air temperature T out，min of the structure to be paved, and the inside air temperature T in of the structure to be paved are known, let the inside air temperature T in of the structure to be paved be equal to the required temperature inside the structure to be paved. At this time, substitute the U i at different i values into T in =(T sc ×h t ×A s -T out，min ×U i ) / (h t ×A s +U i ), until the T in at this i value is equal to the required temperature inside the structure to be paved, and open the corresponding coil layer 9 according to the i value at this time.

[0050] If the T 123...n calculated according to U1, U2, U3...U in are all less than the required temperature inside the structure to be paved, then open all the coil layers 9.

[0051] It should be noted that A is the area, s is the soil; f is the heat flux; T is the temperature, out refers to the outside of the structure to be paved; in refers to the inside of the structure to be paved; U is the heat transfer coefficient, i refers to which layer of the coil layer covered by the structure to be paved, d is the depth; sc is the constant soil temperature; min is the minimum value.

[0052] Specific examples are used in this utility model to elaborate on the principle and implementation mode of this utility model. The description of the above embodiments is only used to help understand the method and its core idea of this utility model; at the same time, for those of ordinary skill in the art, according to the idea of this utility model, there will be changes in the specific implementation mode and application scope. In summary, the content of this specification should not be construed as a limitation to this utility model.
