It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0053] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0054] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0055] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0056] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0057] Due to the existing curtain-pulling transmission system, the insulation blankets are piled irregularly between the curtain support line and the curtain pressure line after being folded. After being folded, they occupy a large area and cause severe shading, which is not conducive to the growth of some light-loving crops. The existing curtain-pulling system can only use thin insulation blankets, but the insulation performance of thin insulation blankets is poor, resulting in the insulation performance of the insulation system with this curtain-pulling transmission form reaching its limit. The existing greenhouse internal insulation system also uses a roll-up insulation system, but it all relies on gravity to unfold downward and roll up, and requires an additional support frame. The application scenarios are very limited, and the additional support frame is expensive and causes severe shading.

[0058] Therefore, the utility model designs a traction roll-up greenhouse insulation system, in which the insulation blanket runs between two slideways, the edges of the insulation blanket are restricted to run in the slideway guide rails, and the insulation blanket is put at one end of the greenhouse or a designated position after being folded, so as not to shade the crops in the greenhouse. A thicker insulation blanket with better insulation performance can be used, which greatly improves the insulation performance of the greenhouse and reduces the energy consumption of winter heating. It can achieve increased insulation effect without shading, which is of great development value.

[0063] Combination Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11It can be seen that the traction system 3 provides direct traction during the unfolding of the sliding thermal insulation blanket 401, and provides tension during the winding of the sliding thermal insulation blanket 401. The traction system 3 includes a traction rope 302, which is connected to the driving edge 404 to drive the driving edge 404 to move from the traction starting point to the traction end point along the trajectory of the guide rail 203; the traction system 3 also includes a guide wheel group; the traction rope 302 is an annular rope, and the guide wheel group supports the annular rope; so that at least a part of the annular rope extends along the trajectory under the projection of the first direction; a annular rope is respectively arranged on both sides of the width of the sliding thermal insulation blanket 401, and the two ends of the length of the driving edge 404 are respectively connected to the annular ropes on both sides of the width of the sliding thermal insulation blanket 401. The annular rope includes a rope body and a driving card 309; the driving card 309 includes a driving card main board 3091, a driving card slave board 3092 and a first connecting member, wherein the first connecting member is a fastening bolt 3093; two driving card slave boards 3092 are respectively arranged on both sides of the surface of the driving card main board 3091 through two fastening bolts 3093, and a clamping space is formed between the driving card main board 3091 and the driving card slave board 3092; the two ends of the rope body are respectively located in the two clamping spaces and clamped by the driving card main board 3091 and the driving card slave board 3092 to form a closed loop; the driving card main board 3091 is connected to the driving edge 404.

[0064] More specifically, the traction wheel group 301 is fixed on the greenhouse column 101, and multiple traction wheel groups 301 are connected in series through the traction transmission shaft 304; the traction power gear 305 is concentrically fixed on the traction transmission shaft 304, providing power for the torsion of the traction transmission shaft 304 to drive the traction transmission shaft 304 to torsion, and the traction rope 302 is sequentially wound around the traction wheel 3011, the guide rope wheel 311, the shaft wheel 3032, the supporting rope wheel 307, the tensioning wheel 306, and the hanging rope wheel 308 to form a closed loop path; the traction wheel 3011 drives the traction rope 302 to move on the closed loop path through the friction between the traction rope 302 and the traction rope 302;

Fig.17 Fig.18The travel path of the driving edge 404 is restricted and fixed, and thus the travel path of the driving card 309 is also restricted and fixed. The rope support wheel 307 has two groove wheels, and the distance between the two groove wheels is smaller than the length of the driving card 309, which reduces the failure of the driving card 309 when it travels to the position of the rope support wheel 307; Figure 8 Fig. 9 As shown, by tightening the fastening bolts 3093, the traction rope 302 is tightly clamped between the drive card main board 3091 and the drive card slave board 3092. The inner surfaces of the drive card main board 3091 and the drive card slave board 3092 have protrusions to increase the friction with the traction rope 302; the shapes of the drive card main board 3091 and the drive card slave board 3092 match each other tightly.

[0067] like Figure 5 Figure 6 Figure 7 As shown, the traction wheel assembly 301 is composed of a traction wheel 3011, a traction wheel bracket 3012, a guide rope roller 3013, and a sleeve 3014. The traction wheel 3011 is an integrally formed metal casting. The surface of the traction wheel rope groove 3011a has multiple protrusions to increase the friction between the traction wheel rope groove 3011a and the traction rope 302. The end of the traction wheel shaft joint 3011b is a "straight" key or spline, which is convenient for better connection and disassembly with the traction transmission shaft 304. The traction wheel shaft joint 3011b rubs in the sleeve 3014. The sleeve 3014 is preferably a copper sleeve with good durability and lubrication performance. The sleeve 3014 is embedded in the traction wheel bracket 3012; the guide rope roller 3013 is preferably a pulley or roller, which is used to guide the traction rope 302 to enter and leave the traction wheel 3011.

[0068] like Fig.10 Fig.11As shown, the tensioning wheel 306 is composed of a movable frame 3062, a fixed frame 3063, a spring 3064, a spring pad 3065, an extension bolt 3066, and a pre-tightening nut 3067; the rope pulley 3061 is fixed to the movable frame 3062, and the traction rope 302 passes around the rope pulley 3061 and then turns back, generating an upward pulling force on the tensioning wheel 306, and the movable frame 3062 can move up and down along the extension bolt 3066 in the fixed frame 3063, and the fixed frame 3063 is fixed on the greenhouse column 101, and the spring 3064 presses against the fixed frame 3063 to generate a downward thrust on the movable frame 3062 by squeezing the spring pad 3065 and the pre-tightening nut 3067. When the traction rope 302 becomes longer due to thermal expansion and contraction or other reasons, the upward pulling force will decrease, and the traction rope 302 will become loose, reducing the friction between the traction rope 302 and the traction wheel 3011, which may easily cause a malfunction. The tensioning wheel 306 will generate a downward pulling force on the traction rope 302 to ensure that the traction rope 302 is in a taut state, thereby increasing the stability of the traction system.

[0069] Combination Figure 1 , Fig.12 , Fig.13 , Fig.14 , Fig.15 , Fig.16 , Fig.17 , Fig.18 The winding system 4 includes a winding shaft 403 that can rotate around its own axis. The other end of the sliding insulation quilt 401 is fixed on the winding shaft 403. The sliding insulation quilt 401 is wound around the outer periphery of the winding shaft 403. When the winding shaft 403 rotates around the winding direction, the sliding insulation quilt 401 drives the driving edge 404 to move along the trajectory line from the traction end point to the traction starting point. In the process of the traction rope 302 driving the driving edge 404 to move along the trajectory line of the guide rail 203 from the traction starting point to the traction end point, the winding system 4 provides traction resistance for the traction rope 302; when the winding shaft 403 rotates around the winding direction, the traction rope 302 provides winding resistance for the winding shaft 403.

[0070] More specifically, one end of the sliding thermal insulation quilt 401 is fixed on the quilt winding shaft 403, and most of the sliding thermal insulation quilt 401 is wound on the quilt winding shaft 403 when winding; the other end of the sliding thermal insulation quilt 401 is fixed on the driving edge 404, and moves with the driving edge 404 during the unfolding and winding process, and the quilt winding shaft 403 is fixed on the greenhouse through the quilt winding shaft support 402, and the quilt winding shaft 403 can be twisted in the quilt winding shaft support 402; the winding power gear 405 is fixed on the quilt winding shaft 403, and the rotation of the winding power gear 405 drives the rotation of the quilt winding shaft 403, thereby realizing the winding of the sliding thermal insulation quilt 401.

[0071] Combine 13 Fig.14 Fig.15 Fig.16 It can be seen that the sliding insulation quilt 401 is a specially treated insulation quilt, which includes an insulation quilt inner core 4011, a lock edge rope 4012, an insulation quilt fabric 4013, and an insulation quilt cavity 4014, wherein the insulation quilt inner core 4011 is the main insulation material, and the insulation quilt inner core 4011 is preferably pearl cotton, because pearl cotton has the characteristics of waterproof, light weight, and high thermal resistance; the outer side of the insulation quilt inner core 4011 is the insulation quilt fabric 4013, and the insulation quilt fabric 4013 is preferably PE woven cloth, because PE woven cloth has the advantages of good tensile strength and wear resistance, the inner core 4011 of the thermal insulation quilt is sewn and fixed with the thermal insulation quilt outer material 4013; a locking edge rope 4012 is respectively arranged on both sides of the width of the sliding thermal insulation quilt 401, and the locking edge rope 4012 is inserted into the thermal insulation quilt sliding groove 2033. The diameter of the locking edge rope 4012 is larger than the opening width of the thermal insulation quilt sliding groove 2033, and the guide rail 203 blocks the locking edge rope in the direction toward the sliding thermal insulation quilt 401. Specifically, the locking edge rope 4012 is located on the long side of the thermal insulation quilt, and the thermal insulation quilt outer material 4013 is outside the locking edge rope 4012, and the thermal insulation quilt outer material 4013 wraps the locking edge rope 4012, such as Figure 2 As shown, the edge locking rope 4012 is in the insulation quilt sliding groove 2033, and the diameter of the edge locking rope 4012 is larger than the opening of the insulation quilt sliding groove 2033, so that the edge of the insulation quilt cannot slide out of the track, which limits the operation range of the sliding insulation quilt 401 and increases the flatness of the unfolding and winding of the insulation quilt; because the length and thickness of the sliding insulation quilt 401 that can be applied by the utility model are greatly improved, the pulling force generated by the driving edge 404 pulling the sliding insulation quilt 401 is very large, so the utility model designs a new insulation quilt fixing method, such as Fig.16 As shown, the driving edge 404 includes a lower mounting groove 4041 of the driving edge, an upper mounting groove 4042 of the driving edge, a fixed quilt cavity 4043, and a latch 4044. The specific fixing method is to first insert the thermal insulation quilt cavity 4014 into the fixed quilt cavity 4043, and then insert the latch 4044 into the thermal insulation quilt cavity 4014. The thermal insulation quilt cavity 4014 is made of the thermal insulation quilt fabric 4013. The fixed quilt cavity 4043 is preferably a circular cavity or an elliptical cavity as shown in the figure. The latch 4044 is preferably a small-section steel pipe. The diameter of the latch 4044 is larger than the opening size of the fixed quilt cavity 4043. Therefore, after the latch 4044 is inserted into the thermal insulation quilt cavity 4014, the sliding thermal insulation quilt 401 will not be separated from the driving edge 404 unless the fabric is torn as a whole after being subjected to tension. This installation method is evenly stressed, and there is no insertion and no damage to the sliding thermal insulation quilt 401.

[0072] like Figure 8 , Fig.17As shown, the lower mounting groove 4041 of the driving side is used to fix the driving card 309, and the upper mounting groove 4042 of the driving side is used to fix the pulley fixing member 407; the pulley 406 is fixed on the pulley fixing member 407, and the pulley fixing member 407 is fixed to the driving side 404 by fixing bolts 408. After the above fixing is completed, the pulleys 406 are fixed at both ends of the driving side 404, and can slide along the guide rail in a limited position;

[0073] Combination Figure 1 , Figure 4 , Fig.12 , Fig.19 , Fig. 20 , Fig.21 The power system 5 provides the power source and tension source during the unfolding and winding of the sliding thermal insulation blanket 401. The motor 501 is the power source of the entire system. The motor 501 transmits the power to the gear box 502, and the gear box 502 transmits the power to the traction output shaft 504a or the winding output shaft 504b through the internal gear mechanism; the traction brake 503a and the winding brake 503b are important components for providing tension, preferably magnetic powder brakes, because the magnetic powder brake is based on the principle of electromagnetic induction, and the resistance provided is linearly positively correlated with the current or voltage. The resistance torque of the magnetic powder brake is controllable and adjustable, ensuring that the provided tension matches the tension required for the operation of the thermal insulation blanket.

[0074] Working condition 1: The gear box 502 transmits power to the traction output shaft 504a through the internal gear machinery, and the traction gear 505a is fixedly connected to the traction output shaft 504a. Then the traction output shaft 504a transmits power to the traction gear 505a, and the traction gear 505a transmits power to the traction power gear 305 through the chain 506, thereby introducing power into the traction system. At the same time, the winding brake 503b is energized to ensure the tension required for the operation of the traction system, so that the insulation is always in a tensioned state to prevent the insulation from being over-released or loosened.

[0075] Working condition 2: The gear box 502 transmits power to the winding output shaft 504b through the internal gear machinery, and the winding gear 505b is fixedly connected to the winding output shaft 504b. Then the winding output shaft 504b transmits power to the winding gear 505b, and the winding gear 505b transmits power to the winding power gear 405 through the chain 506, thereby introducing power into the winding system. At the same time, the traction brake 503a is energized to ensure the tension required for the operation of the winding system, so that the insulation blanket is always in a tensioned state to prevent the insulation blanket from slipping or loosening.

[0076] like Fig.21 The figure shows a simple schematic diagram of a gearbox.

[0077] The input shaft 5021 obtains power from the motor 501. The input shaft 5021 is preferably a spline shaft, so that the sliding gear 5022 can not only rotate with the input shaft 5021 but also slide up and down on the input shaft 5021; one end of the shift fork 5023 is clamped on the sliding gear 5022 and the other end is fixed on the shift shaft 5024. The shift shaft 5024 can move up and down according to control needs, and then the shift fork 5023 controls the sliding gear 5022 to move up and down;

[0078] The traction internal gear 5026a is fixed on the traction output shaft 504a, and the traction output shaft 504a is fixed on the gear box housing 5027 through the bearing 5025. The winding internal gear 5026b is fixed on the winding output shaft 504b, and the winding output shaft 504b is fixed on the gear box housing 5027 through the bearing 5025.

[0079] Under working condition 1, the operation inside the gear box 502 is as follows: the shift shaft 5024 moves upward, and then the shift fork 5023 controls the sliding gear 5022 to move upward, so that the sliding gear 5022 is engaged with the traction internal gear 5026a, and the power is transmitted to the traction output shaft 504a, thereby achieving the power transmission condition described in working condition 1.

[0080] Under working condition 2, the operation inside the gear box 502 is as follows: the shift shaft 5024 moves downward, and then the shift fork 5023 controls the sliding gear 5022 to move downward, so that the sliding gear 5022 engages with the winding internal gear 5026b, and transmits power to the winding output shaft 504b, thereby achieving the power transmission condition described in working condition 2.

[0081] Different from the above-mentioned embodiments, the traction drive shaft 304, traction power gear 305 of the traction system 3 and the quilt reel shaft 403, winding power gear 405 of the winding system 4 are on the same side of the greenhouse 1 and driven by one motor and one gearbox. In other embodiments, the traction drive shaft 304, traction power gear 305 of the traction system 3 and the quilt reel shaft 403, winding power gear 405 of the winding system 4 are respectively located at the front and rear sides of the greenhouse 1, specifically, the traction drive shaft 304, traction power gear 305 of the traction system 3 are on the starting side of the sliding insulation quilt 401, and the quilt reel shaft 403, winding power gear 405 of the winding system 4 are on the end side of the sliding insulation quilt 401. The traction system 3 and the winding system 4 are driven by two motors and two gearboxes respectively.

[0082] Combination Figure 1 , Figure 4 , Fig.12 , Fig.19 , Fig. 20 , Fig.21 , Fig. 22 , Fig.23, Fig.24 , Fig.25 The control system 6 controls the unfolding and reeling of the sliding insulation blanket 401 by controlling the electronically controlled components such as the motor 501, the traction brake 503a, and the winding brake 503b.

[0083] The control cabinet 601 is the core of the control system, which is mainly composed of electronic components such as frequency converters and PLC controllers. It can control the speed and direction of the motor 501, receive the switch signals of the end limiter 602 and the starting limiter 603, and process them according to the preset program.

[0084] The end point limiter 602 and the start point limiter 603 are preferably touch-controlled travel limit switches.

[0085] 1. Based on the description of the above systems and combined Fig. 22 and Fig.23 , demonstrating the unfolding process of the traction roll-up greenhouse insulation system insulation blanket:

[0086] like Fig. 22 As shown, the control cabinet 601 sends a command to the motor 501 to turn it on, the motor 501 generates a preset direction and speed and transmits power to the traction drive shaft 304 through the power system 5, the traction drive shaft 304 rotates clockwise, driving the traction wheel 3011 to rotate counterclockwise, the traction wheel 3011 drives the traction rope 302, the traction rope 302 drives the driving edge 404 to move in the direction indicated by the arrow through the driving card 309, the driving edge 404 pulls the sliding thermal insulation blanket 401 to move in the direction indicated by the arrow, and the thermal insulation blanket begins to unfold;

[0087] At the same time, the control cabinet 601 sends a command to the winding brake 503b, so that the winding brake 503b is energized to generate a preset resistance, which makes the thermal insulation quilt always in a tensioned state during the entire unfolding process.

[0088] like Fig.23 As shown, when the driving edge 404 pulls the sliding insulation blanket 401 to the designated position on the right, the insulation blanket is fully unfolded, and the driving edge 404 touches the end limiter 602. The end limiter 602 transmits the contact signal to the control cabinet 601, and the control cabinet 601 sends a command to the motor 501 to close it, and the unfolding process of the insulation blanket of the traction and roll-up greenhouse insulation system ends.

[0089] 2. Based on the description of the above systems and combined Fig.24 and Fig.25 , demonstrating the process of rolling up the insulation blanket of the traction roll-up greenhouse insulation system:

[0090] like Fig.24As shown, the control cabinet 601 sends a command to the motor 501 to open it, and the motor 501 generates a preset direction and speed and transmits power to the quilt winding shaft 403 through the power system 5. The quilt winding shaft 403 rotates counterclockwise, rolling up the sliding thermal insulation quilt 401, and pulling the sliding thermal insulation quilt 401 to move in the direction indicated by the arrow, and the thermal insulation quilt is rolled up and unfolded;

[0091] At the same time, the control cabinet 601 sends a command to the traction brake 503a, so that the traction brake 503a is energized to generate a preset resistance, which makes the thermal insulation quilt always in a tensioned state during the entire winding process.

[0092] like Fig.25 As shown, when the driving edge 404 pulls the sliding insulation blanket 401 to the designated position on the left, the insulation blanket is completely rolled up, and the driving edge 404 touches the starting limiter 603. The starting limiter 603 transmits the contact signal to the control cabinet 601, and the control cabinet 601 sends a command to the motor 501 to turn it off, and the winding process of the insulation blanket of the traction roll-up greenhouse insulation system ends.

[0093] In summary, the traction and roll-up greenhouse insulation structure provided by the utility model has the following beneficial effects:

[0094] 1. The utility model uses a traction wheel to pull the thermal insulation quilt to unfold, and at the same time uses a brake to provide tension to the winding system to ensure the tension of the thermal insulation quilt.

[0095] 2. Most of the existing greenhouse transmission systems use a winch-type winding wheel to drive the traction rope. The disadvantage of the winch-type driving rope is that the stroke is short. The utility model uses a traction wheel to drive the rope. The traction wheel drives the traction rope through friction, and the closed loop of the rope is cleverly connected to the drive card position. This driving stroke is very long, and theoretically the driving stroke is the largest.

[0096] 3. The guide rails of the utility model are cleverly combined with the main structure of the greenhouse. The guide rails are connected to the greenhouse beams through guide rail connectors. The guide rails are usually arranged and the guide rail connectors are disconnected (about one is arranged every 1-2 meters). There is a small space between the guide rails and the greenhouse beams to install the original greenhouse plant hanging or fill light and other equipment, which does not affect the original greenhouse function at all.

[0097] 4. The utility model designs a novel driving edge, which makes the connection between the thermal insulation quilt and the driving edge more secure and will not cause damage to the thermal insulation quilt.

[0098] 5. The guide rail of the utility model is designed with three functional cavities, which are used to fix the sealed insulation quilt, slide the insulation quilt, and slide the roller from bottom to top. The three cavities are organically combined on a guide rail profile, and the system is integrated together to increase the aesthetics and functionality.

[0099] In general, the traction and roll-up greenhouse insulation structure designed by the utility model has a sliding insulation blanket running between two slideways, and the edges of the sliding insulation blanket are restricted to run within the slideway guide rails. After the sliding insulation blanket is folded, it is placed at one end of the greenhouse or a designated position, and does not shade the crops in the greenhouse.

[0100] The greenhouse insulation system designed by the utility model can use thicker sliding insulation blankets with better insulation performance, greatly improving the insulation performance of the greenhouse and reducing winter heating energy consumption. It can increase the insulation effect without shading, and has great development value.

It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
