Description

Technical Field

[0001] This utility model relates to the field of curtain technology, and more specifically, it relates to a high-efficiency and quick-installation system for greenhouse curtains. Background Technology

[0002] In modern greenhouse cultivation environments, to meet the diverse needs of crops for light, temperature, and humidity, curtain systems are often installed on the top or side walls of the greenhouse to provide functions such as shading, heat preservation, and cooling. These curtains are typically made of flexible materials, offering good light transmission, heat retention, and foldability. They can be unfolded or retracted according to environmental changes, thereby improving the microclimate inside the greenhouse and increasing crop yield and quality.

[0003] In existing technologies, the installation and operation of greenhouse curtains are mostly done manually, especially in simple greenhouse structures, where the curtains are often manually pulled to unfold or retract. To fix the curtains in place, clips, nails, spring clips, or slots are used to secure them to the side of the greenhouse frame along their edges. This method is not only labor-intensive and inefficient, but also requires installers to climb, posing a certain risk. Furthermore, the installation precision is low, and uneven stress can easily cause the curtains to wrinkle, wear, or even tear, severely affecting their lifespan and shading effect.

[0004] Chinese patent document CN113210392A discloses a dustproof curtain system. Although it realizes the automatic extension and retraction of the curtain, its structure does not have a traction module. Instead, the curtain is directly pulled by a motor, which is prone to damage. In addition, the lack of effective traction path constraints makes the curtain prone to deviation, tearing, or even ripping during the pulling process, which limits the actual application effect and promotion value of the system.

[0005] Therefore, this application proposes a high-efficiency and quick-installation system for greenhouse curtains. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-efficiency and fast installation system for greenhouse curtains that achieves rapid installation and disassembly of the curtains by using a traction component and a winding machine.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A high-efficiency and quick-installation system for greenhouse curtains includes a frame, the frame including two sets of longitudinal bars, the longitudinal bars being provided with sliding grooves, the two sets of sliding grooves being arranged facing each other, a curtain being slidably arranged inside the sliding grooves, a traction component being provided at one end of the curtain, a traction rope being provided at the end of the traction component away from the curtain, and one end of the traction rope being wound around a winding machine.

[0009] The curtain includes a curtain body, with flat strips on both sides of the curtain body and sliders at the ends of the flat strips, the sliders being slidably connected to the slide grooves.

[0010] The present invention is further configured such that a set of notches are respectively opened on both sides of one end of the curtain body.

[0011] The present invention is further configured such that: the flat strip is sewn to both sides of the curtain body by stitches, the flat strip is made of rubber or polymer material, including polyolefin, polytetrafluoroethylene, polyvinylidene fluoride, PA, PET, PVC, etc., and the stitches are located at the axial center of the flat strip.

[0012] The present invention is further configured such that: a groove is provided on the slider, and the flat strip passes through the groove.

[0013] The present invention is further configured such that: the traction component is configured as a trapezoidal structure with an extended bottom, and two sets of circular holes are provided through the traction component, through which the traction rope passes.

[0014] The present invention is further configured such that a reinforcing steel ring is provided around the circumference of the circular hole.

[0015] The present invention is further configured such that: the traction rope is configured as a Y-shaped structure, one end of the traction rope is provided with a fork, and the two ends of the fork are respectively wound with round holes.

[0016] The present invention is further configured such that: the frame also includes a horizontal bar arranged perpendicular to the stabilizing structure, and the bottom of the vertical bar is provided with a stabilizing structure, the stabilizing structure including several sets of triangular support bars and bottom bars.

[0017] The present invention is further configured such that: the frame also includes an adjusting rod, the position of the adjusting rod is adjustable, and the traction assembly extends from the top of the adjusting rod to the winding machine.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. This high-efficiency, quick-installation greenhouse curtain system adopts a modular design, facilitating installation and disassembly. It enables rapid installation of greenhouse curtains whenever needed during greenhouse construction. Key components in the frame structure, such as sliding tracks, adjusting rods, and traction components, are all detachable. The flat strips and sliders are embedded, facilitating quick curtain replacement and maintenance, significantly improving system installation efficiency. It is particularly suitable for greenhouses with frequent structural changes and initial construction phases, overcoming the traditional limitation that greenhouse curtains can only be installed before crops have matured, achieving flexible curtain deployment throughout the entire greenhouse growth cycle.

[0020] 2. The traction component adopts a trapezoidal structure with a widened bottom. The traction rope is connected through two sets of round holes with reinforced steel rings, effectively distributing the concentrated tension area and preventing tearing caused by prolonged installation. This significantly improves the stability of the curtain during unfolding and retraction. Furthermore, the traction rope is designed with a Y-shaped structure, with the main rope branching and connecting to both ends of the traction component. This effectively avoids curtain skewing or jamming caused by uneven force, ensuring the symmetry and synchronization of the curtain during unfolding and retraction, and improving the overall system reliability.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0034] Example 1, please refer to Figure 1-4 The present invention provides the following technical solution: The present invention provides a high-efficiency and quick-installation system for greenhouse curtains, including a frame 1, a curtain 2, a traction component 3, a traction rope 4, and a winding machine 5.

[0035] See Figure 1 The frame 1 is an integral support structure, including two sets of longitudinally parallel rods 11. Each set of longitudinal rods 11 is provided with a sliding groove 16, which are arranged opposite to each other, forming a pair of guide rail structures. A curtain 2 is slidably installed inside the sliding groove 16, allowing the curtain 2 to be freely unfolded and retracted in the longitudinal direction within the sliding groove 16.

[0036] Frame 1 also includes horizontal bars 12 perpendicular to the longitudinal bars 11, used to connect the longitudinal bars 11 and enhance the overall rigidity and stability of the structure. To further improve the support capacity, a stabilizing structure 13 is provided at the bottom of the longitudinal bars 11. The stabilizing structure 13 is composed of several sets of triangular support bars and bottom bars. Each triangular support bar, together with the longitudinal bars 11 and the bottom bars, forms a triangular structure, which can effectively distribute the upper load and prevent the structure from tilting.

[0037] The frame 1 is also equipped with an adjusting rod 14, which is mounted on the base rod of the stable structure 13 and can be adjusted in position in the horizontal direction. The traction component 3 extends from the top of the adjusting rod 14 to the winding machine 5, and can adjust the tension angle and sag of the curtain 2 according to the usage scenario, thereby improving the versatility and adaptability of the system.

[0038] The curtain 2 includes a curtain body 21, one end of which is wound around a roller to form a fabric roll. The curtain body 21 is made of a flexible material and is suitable for shading, heat preservation, or cooling in greenhouse environments. Flat strips 212 are provided on both sides of the curtain body 21. The flat strips 212 are made of rubber and have good elasticity and friction properties. The width of the flat strips 212 is set to 0.5 cm to 10 cm, and the thickness is set to 1 mm to 100 mm. The flat strips 212 are sewn to both sides of the curtain body 21 by seams 213. The seams 213 are located on the axial center line of the flat strips 212, ensuring a firm connection with the curtain body 21 and providing a certain degree of tensile adaptability.

[0039] A slider 22 is connected to the end of the flat strip 212. One end of the slider 22 has a pointed tip for easy installation. The slider 22 slides in conjunction with the slide groove 16, allowing the curtain 2 to move smoothly within the groove. The materials of the flat strip 212 and the slider 22 can be polyolefin, polytetrafluoroethylene, polyvinylidene fluoride, PA, PET, and PVC. Preferably, in this embodiment, polyolefin is used. A groove 221 is provided on the slider 22, and the flat strip 212 passes through the groove 221, thereby reliably fixing the slider 22 to the flat strip 212. This structure facilitates the disassembly and maintenance of the slider 22 and avoids the problem of being unable to replace parts of the curtain 2 after overall damage.

[0040] In addition, a set of notches 211 are provided on both sides of one end of the curtain body 21. This structure is used to avoid obstacles when the curtain body is inserted into the slide groove, improve the installation efficiency and smoothness of the curtain, and effectively improve the overall system's operational stability and durability.

[0041] A traction component 3 is fixedly connected to one end of the curtain 2. The traction component 3 has a trapezoidal structure with a widened bottom to increase traction stability and evenly distribute the tensile load. Two sets of circular holes 31 are provided through the traction component 3. The traction rope 4 extends from the end of the traction component 3 away from the curtain 2 and passes through the two sets of circular holes 31 in sequence. Each set of circular holes 31 is equipped with a reinforcing steel ring around its perimeter to prevent tearing or deformation of the hole due to prolonged pulling, thereby improving durability.

[0042] The traction rope 4 has a Y-shaped structure, with one end being the main rope segment and the other end forking into two branch rope segments. These branches are then fixedly connected after passing through the two sets of round holes 31 of the traction component 3, thereby enabling the traction force to be evenly distributed to both ends of the traction component and improving the stability and smoothness of the curtain 2 when it is unfolded or retracted.

[0043] The other end of the traction rope 4 is wound and connected to the winding machine 5. The winding machine 5 can be an electric drive mechanism used to control the winding and unwinding of the traction rope 4, thereby realizing the automatic lifting and lowering and rapid unfolding and retraction of the curtain 2, which is compatible with the requirements of the greenhouse automatic control system.

[0044] Example 2, please refer to Figure 5 This embodiment provides a modified structure for the interaction between the traction component 3 and the traction rope 4. The traction component 3 is designed as a triangular structure, which is simpler than the trapezoidal structure in Embodiment 1, and helps to reduce the overall weight of the traction component. The traction component 3 has only one set of circular holes 31, and these circular holes 31 are located at the top of the traction component 3. The traction rope 4 has a standard structure and is not designed as a Y-shaped fork structure, but instead passes directly through the circular holes 31 and is fixedly connected. This structure simplifies the laying path of the traction rope and is suitable for curtain systems with lighter loads or structural constraints.

[0045] Example 3, please refer to Figure 6When the curtain uses a thicker curtain body 21, the Y-shaped traction method in Embodiment 1 may lead to a slower traction speed, and there is even a risk that the traction rope 4 may break due to uneven force. Therefore, this embodiment provides an improved traction method. Specifically, two traction ropes 4 are threaded through each circular hole 31 in the traction assembly 3, and the two traction ropes are respectively connected to their respective independent winding machines 5. Through the coordinated drive of the two sets of winding machines 5, the two traction ropes 4 can be driven synchronously, thereby stabilizing the traction assembly 3 and driving the curtain to unfold or retract. This method is suitable for the pulling needs of high-load, large-area curtains, effectively improving the traction efficiency and safety of the system.

[0046] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
