Technical Field

[0001] This invention relates to the field of agricultural facilities technology, and more specifically, to a greenhouse system. Background Technology

[0002] A greenhouse is a type of building widely used in plant cultivation and agricultural production. Because greenhouses can control factors such as temperature, humidity, light, and carbon dioxide concentration, they provide a suitable and stable environment for plant growth, unaffected by climate or outdoor temperature and humidity. Greenhouses can provide the necessary heat and light for growing plants, allowing for fully controlled plant growth and significantly improving crop yield and quality.

[0003] As a mainstream type of high-efficiency and energy-saving greenhouse, the ridge-truss connection is the core component supporting the overall structural stability of the greenhouse. The ridge is the load-bearing center of the greenhouse roof, mainly bearing the roof load, resisting wind uplift, and resisting snow pressure. The trusses (also known as roof purlins) are the key components that transfer the load to the columns. How to quickly install the ridge and trusses while ensuring connection strength and stability is an urgent problem to be solved. Summary of the Invention

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] Please refer to Figures 1-13 This embodiment provides a greenhouse system, including a ridge 100, a gutter 200, a stringer connector 300, and pairs of stringers 400. The stringers 400 are lateral load-bearing components used to support the greenhouse system.

[0027] The truss 400 includes a truss top structure 410 and a truss bottom structure 420 that are fixedly connected to each other. For example, the truss top structure 410 is located above the truss bottom structure 420. The truss 400 also includes a first end and a second end corresponding to each other along its extension direction. At the first end of the truss 400, the truss top structure 410 of each pair of trusses 400 is respectively inserted into both sides of the ridge 100, and the truss bottom structure 420 of each pair of trusses 400 is connected to the truss connector 300. At the second end of the truss 400, both the truss top structure 410 and the truss bottom structure 420 are fixedly connected to the gutter 200. Through the mutual cooperation of the ridge 100, the gutter 200, the truss connector 300 and the truss 400, a frame structure of a greenhouse system with better connection strength and better connection stability is formed.

[0028] Along the extension direction of the ridge 100, the stringers 400 are sandwiched between pairs of stringer connectors 300, so that the pairs of stringer connectors 300 are fixedly connected to the first ends of the pairs of stringers 400. Optionally, the stringer connectors 300 are provided with through holes for fasteners to pass through; the fasteners pass through the through holes of the pairs of stringer connectors 300 in sequence, so that the stringers 400 are sandwiched between the pairs of stringer connectors 300, thereby fixing the first ends of the pairs of stringer connectors 300 to the first ends. Optionally, the top of the stringer connector 300 is provided with a positioning protrusion 331, which faces downward, and the bottom of the stringer 400 is provided with a positioning groove that mates with the positioning protrusion 331. The positioning protrusions 331 and positioning grooves facilitate the installation of the stringer connectors 300. During installation, simply align the positioning protrusions 331 of the two paired stringer connectors 300 with the positioning grooves at the bottom of the stringer 400. Optionally, the positioning groove is formed by stamping the bottom of the stringer 400 to deform it, ensuring that the bottom of the stringer 400 does not break at the positioning groove. Compared to a punched groove, the positioning groove, formed by deforming the bottom of the stringer 400, does not reduce the strength of the stringer 400 and may even increase it to some extent.

[0029] The greenhouse system described in this embodiment includes a ridge 100, a gutter 200, stringer connectors 300, and pairs of stringers 400. At the first end of each pair of stringers 400, the top structure 410 of each pair of stringers 400 is inserted into both sides of the ridge 100, and the bottom structure 420 of each pair of stringers 400 is connected to the stringer connectors 300. Specifically, the pairs of stringer connectors 300 are fixedly connected to the first ends of the pairs of stringers 400. That is, along the extension direction of the ridge 100, the stringers 400 are sandwiched between the pairs of stringer connectors 300, enabling rapid installation of the ridge 100 and the stringers 400. This effectively ensures the connection strength and stability between the ridge 100 and the stringers 400, and avoids the need for pre-drilled holes for connecting the stringer connectors 300 in the stringers 400, as is done in the prior art, thus guaranteeing the connection strength performance of the stringers 400 to a certain extent.

[0030] In Venlo-type greenhouses, the connection stability between the ridge 100 and the truss 400 is not only limited to preventing structural collapse, but also extends to three major aspects: load transfer optimization, internal environment protection, and economic cost control. It directly determines the practicality, safety, and cost-effectiveness of the greenhouse and is one of the core design points for Venlo-type greenhouses to meet the needs of large spans, high loads, and long-term use.

[0031] In the prior art, through holes for connecting the stringer connectors 300 are usually pre-drilled on the stringer 400. During installation, fasteners need to be inserted into the through holes on the stringer connectors 300 and the through holes on the stringers 400 on both sides of the ridge 100. The through holes on one side of the ridge 100 stringer 400 are easier to install, while the through holes on the other side stringer 400 are difficult to align. To reduce the processing and installation difficulty of the profiles, while ensuring the roof strength, the greenhouse system described in this embodiment modifies the connection between the truss 400 and the truss connector 300. Pre-drilled holes for connecting the truss connector 300 are no longer required on the truss 400. On-site installation simply involves snapping the paired truss connectors 300 onto the bottom structure 420 of the paired truss 400. Fasteners (e.g., bolts) do not need to pass through the truss 400; they only need to pass through the paired truss connectors 300 to secure it. This achieves a rapid assembly effect, reduces the processing steps of the truss 400, saves costs to a certain extent, and effectively ensures the connection strength performance of the truss 400. The method of connecting the truss 400 with paired truss connectors 300 is beneficial to the connection strength and stability between the ridge 100 and the truss 400.

[0032] See Figures 9-13 As shown, in the optional embodiment, the bottom structure 420 of the stringer includes a first plate portion 421, a second plate portion 422, and a connecting portion 423; the first plate portion 421 is fixedly connected to the top structure 410 of the stringer.

[0033] One end of the truss bottom connecting part 423 is connected to the middle of the first plate part 421 of the truss bottom, and the other end of the truss bottom connecting part 423 is connected to the middle of the second plate part 422 of the truss bottom, so that the first plate part 421, the second plate part 422 of the truss bottom and the truss bottom connecting part 423 form two truss bottom grooves 424; the two truss bottom grooves 424 are located on both sides of the truss bottom connecting part 423.

[0034] Optionally, the stringer connector 300 includes a connecting plate portion 310; the connecting plate portion 310 is triangular; a bottom flange 320 and two top flanges 330 are connected to the same surface of the connecting plate portion 310; there is a gap between the bottom flange 320 and the top flanges 330; a bottom connecting portion 423 is sandwiched between the top flanges 330 of the paired stringer connectors 300, and at least part of the top flanges 330 is located in the bottom groove 424, so that the stringer 400 is sandwiched between the paired stringer connectors 300. The gap between the bottom flange 320 and the top flange 330 ensures that when the bottom connecting portion 423 is sandwiched between the top flanges 330 of the paired stringer connectors 300, the stringer connector 300 and the bottom structure 420 of the stringer do not interfere with each other, which is beneficial for achieving the sandwiching of the bottom connecting portion 423 between the top flanges 330 and the bottom connecting portion 423.

[0035] Optionally, the top fold 330 is snapped into the bottom groove 424.

[0036] Optionally, the second plate portion 422 of the truss bottom passes through the gap between the bottom flange 320 and the top flange 330, so that the truss bottom connection portion 423 is sandwiched between the top flanges 330 of the paired truss connectors 300.

[0037] See Figure 12 As shown, in an optional embodiment, the top folded edge 330 is provided with a positioning protrusion 331, which faces the bottom folded edge 320.

[0038] The second plate portion 422 of the truss base is provided with a positioning groove that mates with the positioning protrusion 331. The positioning protrusion 331 and the positioning groove facilitate the installation of the stringer connectors 300; that is, during installation, it is only necessary to align the positioning protrusions 331 of the two paired stringer connectors 300 with the positioning grooves of the second plate portion 422. Optionally, the positioning groove is formed by stamping the surface of the second plate portion 422 to deform it, ensuring that the second plate portion 422 does not break at the positioning groove. Compared to a drilled groove, the positioning groove, formed by deforming the second plate portion 422, does not reduce the strength of the stringer 400 and may even increase its strength to some extent.

[0039] See Figure 9As shown, in an optional embodiment, the size of the top fold 330 is smaller than the size of the bottom fold 320 along the thickness direction of the stringer connector 300; the size of the top fold 330 is smaller than the size of the bottom fold 320 so that the bottom connecting portion 423 can be sandwiched between the top folds 330 of the paired stringer connectors 300.

[0040] Optionally, along the thickness direction of the truss connector 300, the sum of half the size of the bottom connection portion 423 and the size of the top folded edge 330 is consistent with the size of the bottom folded edge 320. By ensuring that the sum of half the size of the bottom connection portion 423 and the top folded edge 330 is consistent with the size of the bottom folded edge 320, when the bottom connection portion 423 is sandwiched between the top folded edges 330 of the paired truss connectors 300, the bottom folded edges 320 of the paired truss connectors 300 will contact each other. This facilitates a firm and stable connection between the paired trusses 400 and the ridge 100, thereby ensuring the connection strength and stability between the ridge 100 and the trusses 400.

[0041] See Figure 9 and Figure 10 As shown, in the optional scheme of this embodiment, the bottom structure 420 of the stringer is a symmetrical structure, and the bottom structure 420 of the stringer is symmetrical about the bottom connection part 423. The symmetrical structure of the bottom structure 420 of the stringer is beneficial to the processing and assembly of the bottom structure 420 of the stringer, and its stress distribution is more uniform and symmetrical, which can effectively improve the stability and bending stiffness of the stringer connector 300.

[0042] See Figure 12 and Figure 13 As shown, in the optional embodiment, the connecting plate portion 310 has a weight reduction groove 340. The weight reduction groove 340 can reduce the mass of the stringer connector 300 and reduce the material cost of the stringer connector 300.

[0043] Optionally, the connecting plate portion 310 is provided with a weight-reducing groove flange 341 around the weight-reducing groove 340; the weight-reducing groove flange 341 and the top flange 330 are located on the same surface of the connecting plate portion 310; the strength of the stringer connector 300 can be effectively improved by the weight-reducing groove flange 341.

[0044] Optionally, along the thickness direction of the stringer connector 300, the dimensions of the weight-reducing groove fold 341 are consistent with the dimensions of the bottom fold 320. By ensuring that the dimensions of the weight-reducing groove fold 341 and the bottom fold 320 are consistent, when the bottom connecting part 423 is sandwiched between the top folds 330 of the paired stringer connectors 300, the weight-reducing groove folds 341 of the paired stringer connectors 300 will contact each other. This facilitates a firm and stable connection between the paired stringer connectors 300 and the paired stringers 400, thereby ensuring the connection strength and stability between the ridge 100 and the stringers 400.

[0045] See Figures 8-13 As shown, in an optional embodiment, the connecting plate portion 310 is provided with a through hole for the fastener 500 to pass through; the fastener 500 passes through the through holes of the paired stringer connectors 300 in sequence, and the bottom connecting portion 423 is fastened between the top flanges 330 of the paired stringer connectors 300; the fastener 500 can firmly fix the paired stringer connectors 300 together, thereby fixing the stringer connectors 300 to the paired stringers 400. In this embodiment, the fastener 500 is, for example, a bolt and nut.

[0046] See Figures 8-10 As shown, in an optional embodiment, the top structure 410 of the stringer is provided with a stringer glass groove 411 for cooperating with the glass 600; a stringer through strip 412 is provided between the top structure 410 of the stringer and the glass 600, and the stringer through strip 412 is located within the stringer glass groove 411. The stringer through strip 412 is used to better fix the glass 600 within the stringer glass groove 411, which also facilitates fixing the glass 600 within the stringer 400.

[0047] The purlin insert 412 is generally made of PVC. To address the issues of fading, cracking, and deformation caused by UV rays and high temperatures during prolonged exposure to sunlight, this embodiment optimizes the connection between the purlin top structure 410 and the purlin insert 412. In existing technology, the purlin insert is a single piece threaded through the roof purlin to secure the glass, ensure sealing and waterproofing, and provide cushioning and shock absorption. However, the PVC purlin inserts in existing designs are relatively large, making them prone to deformation during transportation. Furthermore, the exposed portion of the purlin insert suffers from fading, cracking, and deformation after prolonged exposure to sunlight, significantly reducing its lifespan. This embodiment, while maintaining the purlin insert's performance, modifies its shape, placing it between the purlin top structure 410 and the glass 600, thus simplifying installation and effectively extending its lifespan.

[0048] See Figures 1-7 As shown, in an optional embodiment, the greenhouse system further includes a window frame 700, a window opening support rod 710, a window opening push rod 720, and a truss 730; a driving device is connected to the truss 730, and the driving device is connected to the window opening push rod 720 to move the window opening push rod 720 along the extension direction of the vertical ridge 100; the driving device is, for example, a motor. In this embodiment, glass 600 is installed inside the window frame 700.

[0049] A support rod bracket 721 is fixedly connected to the window opening push rod 720; one end of the window opening support rod 710 is pivotally connected to the support rod bracket 721, and the other end of the window opening support rod 710 is hinged to the window frame 700.

[0050] The window frame 700 is rotatably connected to the ridge 100; for example, one end of the window frame 700 is hinged to the other end of the window opening support rod 710, and the other end of the window frame 700 is rotatably connected to the ridge 100. In the greenhouse system described in this embodiment, the window opening push rod 720 is driven to move along the extension direction perpendicular to the ridge 100 by a driving device, so as to drive the support rod bracket 721 to move along the extension direction perpendicular to the ridge 100, thereby driving the window opening support rod 710 to move, and then driving the window frame 700 to rotate around the ridge 100, so as to open or close the window frame 700. Among them, the window opening support rod 710 is a key load-bearing component connecting the drive device and the window frame 700, playing a supporting, transmission, and stabilizing role in the opening and closing of the window; the window opening push rod 720 is the core power actuator of the drive device, directly driving the window opening support rod 710 to move through linear motion, thereby driving the window frame 700 to open and close, playing a key role in greenhouse ventilation and environmental control; the truss 730 is the core load-bearing component of the greenhouse system skeleton, playing an irreplaceable role in the overall strength, stability, and functional realization of the greenhouse. For example, the truss 730 is composed of upper chords, lower chords, and web members (diagonal or vertical members) connected by nodes to form a triangular or polygonal stable structure.

[0051] Optionally, along the extension direction of the ridge 100, window frame 700 is fixedly connected to both sides with window opening limiting clips 740; the window opening limiting clips 740 abut against the purlin 400 to prevent the window frame 700 from moving along the extension direction of the ridge 100, such as... Figure 11 As shown. The window frame 700 is restricted from moving along the extension direction of the ridge 100 by the window opening limiter 740, which facilitates the rotation of the window frame 700 around the ridge 100 and prevents the window frame 700 from being misaligned during opening and closing.

[0052] Optionally, along the extension direction of the ridge 100, there are multiple window frames 700, and the multiple window frames 700 are located on one or both sides of the ridge 100; Figure 11 Two window frames 700 are shown, and the two window frames 700 are located on both sides of the ridge 100.

[0053] In this embodiment, the greenhouse system utilizes a window frame 700, window opening support rods 710, window opening push rods 720, and trusses 730. This allows for rapid installation of the window frame 700, effectively ensuring its connection strength and stability. Furthermore, by fixing window opening limiting clips 740 to both sides of the window frame 700, and having these clips abut against the trusses 400 to prevent movement of the window frame 700 along the extension direction of the ridge 100, drilling into the ridge 100 is avoided, thus ensuring the connection strength and stability of the ridge 100. In other words, this dual improvement in the connection method of the window frame 700 and the setting of the window opening limiting clips 740 effectively ensures the connection strength and stability of the greenhouse system and facilitates the rapid installation of the window frame 700.

[0054] See Figures 1-7 As shown, in an optional embodiment, a base structure 110 is provided at the top of the ridge 100, and a rotating connection structure 750 that cooperates with the base structure 110 is provided at the end of the window frame 700; both the base structure 110 and the rotating connection structure 750 extend along the extension direction of the ridge 100. The window frame 700 rotates around the base structure 110 of the ridge 100 via the rotating connection structure 750.

[0055] Optionally, the base structure 110 includes a base arc surface 113; the base arc surface 113 extends along the extension direction of the ridge 100.

[0056] The rotating connection structure 750 has an inwardly recessed enveloping arc surface 753; the curvature of the enveloping arc surface 753 is adapted to the curvature of the base arc surface 113; the enveloping arc surface 753 extends along the extension direction of the ridge 100; the enveloping arc surface 753 can envelop the base arc surface 113, and when the window frame 700 rotates around the ridge 100, the enveloping arc surface 753 can rotate along the base arc surface 113.

[0057] The enveloping arc surface 753 surrounds the base arc surface 113; the rotating connection structure 750 rotates about the axis of rotation of the base arc surface 113, thereby allowing the window frame 700 to rotate about the axis of rotation.

[0058] The greenhouse system described in this embodiment uses an envelope arc surface 753 to cooperate with a base arc surface 113, which effectively ensures the contact area during rotation. The contact area is large during rotation, the force is more uniform, and it can withstand greater loads. Compared with ordinary pin hinges, it is more wear-resistant and has better stability.

[0059] See Figures 1-7As shown, in the optional scheme of this embodiment, the envelope arc surface 753 is an envelope groove structure; the envelope groove structure is C-shaped and larger than a semicircle. By making the envelope groove structure larger than a semicircle, it can be ensured that the envelope arc surface 753 does not detach from the base arc surface 113 as much as possible when the window frame 700 rotates around the ridge 100, effectively improving the reliability of the overall connection between the window frame 700 and the ridge 100.

[0060] See Figures 1-7 As shown, in the optional embodiment, the base structure 110 includes a base groove 114; when the window frame 700 is configured to be in the open state, a portion of the enveloping arc surface 753 is located inside the base groove 114; when the window frame 700 is configured to be in the closed state, the enveloping arc surface 753 is located outside the base groove 114, so that when the window frame 700 rotates around the ridge 100 to the open state, the enveloping arc surface 753 is kept as close as possible to the base arc surface 113, effectively improving the reliability of the overall connection between the window frame 700 and the ridge 100.

[0061] See Figures 1-7 As shown, in an optional embodiment, the base structure 110 includes a base mating part 111 and a base support part 112 fixedly connected to the middle position of the base mating part 111; one end of the base support part 112 away from the base mating part 111 is fixedly connected to the top of the ridge 100; the base arc surface 113 is disposed on the base mating part 111, and the base arc surface 113 and the base support part 112 form a base groove 114.

[0062] Optionally, the rotating connection structure 750 includes an envelope portion 751, a stop portion 752, and a rotating connection base 754; the rotating connection base 754 is connected to the end of the window frame 700; the envelope portion 751 and the stop portion 752 are both fixedly connected to the rotating connection base 754, and the envelope portion 751, the stop portion 752, and the rotating connection base 754 form a cavity for accommodating the base mating portion 111 and at least a portion of the base support portion 112; the rotating connection base 754 abuts against the base mating portion 111, for example, the abutment surface between the rotating connection base 754 and the base mating portion 111 includes a plane and / or an arc surface. The envelope portion 751 is located on the side of the base support portion 112 away from the window frame 700, and the stop portion 752 is located on the side of the base support portion 112 closer to the window frame 700; that is, the envelope portion 751 and the stop portion 752 are located on both sides of the base support portion 112.

[0063] Optionally, the envelope portion 751 is a fan-shaped annular column structure, which is larger than a semicircle; the envelope arc surface 753 is disposed on the inner surface of the envelope portion 751; the stop portion 752 is configured to be close to the base support portion 112 when the window frame 700 is closed, and to be far away from the base support portion 112 when the window frame 700 is open; the stop portion 752 helps to improve the stability of the window frame 700 rotation; at the same time, the stop portion 752 can also abut against the base support portion 112 or the ridge 100 in special circumstances to limit the rotation range of the window frame 700, which can effectively prevent the window frame 700 from sliding down as a whole.

[0064] Optionally, the surface on which the base mating part 111 mates with the stop part 752 is the stop mating surface 115, and the stop mating surface 115 is an arc-shaped surface. By making the stop mating surface 115 an arc-shaped surface, the mating area between the base mating part 111 and the stop part 752 can be increased to a certain extent, which can effectively distribute the load and improve the stability and reliability of the window frame 700 when it rotates.

[0065] Optionally, the curvature of the stop mating surface 115 is the same as the curvature of the base arc surface 113. The stop mating surface 115 and the base arc surface 113 are located on both sides of the base support portion 112, and the envelope portion 751 and the stop portion 752 are located on both sides of the base support portion 112. By making the curvature of the stop mating surface 115 the same as the curvature of the base arc surface 113, the structure of the base structure 110 is simplified.

[0066] See Figures 1-7 As shown, in the optional solution of this embodiment, the window opening limiting clip 740 includes an arc-shaped structure; the use of an arc-shaped structure in the window opening limiting clip 740 is beneficial for limiting and guiding the rotation of the window frame 700.

[0067] Optionally, the window opening limiting clip 740 includes a first limiting plate and a second limiting plate fixedly connected. The first limiting plate has an inwardly protruding latching part, which positions the first limiting plate on the window frame 700. The first limiting plate also has a first limiting plate through hole penetrating the latching part. Fasteners pass through the first limiting plate through hole and are fixedly connected to the window frame 700 to secure the first limiting plate to the window frame 700. The second limiting plate is an inwardly bent arc structure. During installation, one window opening limiting clip 740 is first installed on each side of the window frame 700, and then the window frame 700 is installed on the roof ridge 100. The window frame 700 abuts against the purlin 400 through the window opening limiting clip 740, limiting the window frame 700 and preventing misalignment of the window frame 700 during opening and closing.

[0068] See Figures 1-7As shown, in an optional embodiment, the window frame 700 is fixedly connected to a push-pull connector 760, and the window opening support rod 710 is hinged to the push-pull connector 760. The push-pull connector 760 facilitates the hinged connection between the window frame 700 and the window opening support rod 710. For example, the push-pull connector 760 is typically made of metal (such as galvanized steel or aluminum alloy) or high-strength engineering plastic, and its main function is to ensure the smoothness of the push-pull action, structural stability, and sealing performance.
