Description

Technical Field

[0001] This utility model belongs to the field of greenhouse technology, specifically relating to a double-roof fully open greenhouse. Background Technology

[0002] Greenhouses serve multiple functions, including temperature and humidity regulation, pest control, and wind and snow protection. They are widely used in the cultivation of vegetables, fruits, flowers, medicinal herbs, and aquaculture. To more effectively regulate temperature and humidity within greenhouses and meet winter insulation and wind and snow resistance requirements, double-layer greenhouses have been designed. These greenhouses feature double-layered roofs and double-layered membranes, with the membranes opened and closed as needed to regulate temperature and humidity. However, existing double-layered greenhouses require double-layered support frames for the two roof layers, resulting in complex structures, high construction costs, and excessively large gaps between the two roof layers. This compresses the interior space while maintaining the overall height of the greenhouse, reducing its utilization rate. Summary of the Invention

[0003] This invention addresses the problems of high construction cost and low space utilization in existing double-layer greenhouses by providing a double-arched greenhouse. The objective of this invention is achieved through the following technical solution:

[0004] A double-roofed, fully open greenhouse includes an outer frame with internally spaced partition frames dividing the interior into multiple frame units. Each frame unit has a roof unit at its top. Each roof unit includes horizontal beams, longitudinal beams, an upper arch, and a lower arch. The horizontal beams include multiple horizontal beams extending along the X-direction and spaced apart along the Y-direction. The lower arch is positioned above the horizontal beams and includes multiple lower arches spaced apart along the Y-direction. The upper arch frame is spaced above the lower arch frame, with the arch tops of the upper and lower arch frames aligned. The plane of the arch top of the lower arch frame is higher than the plane of the bottom of the upper arch frame. The upper arch frame includes multiple upper arch rods spaced along the Y direction. The longitudinal beam is erected between the upper arch frame and the transverse beam frame. The longitudinal beam frame includes multiple longitudinal uprights extending along the Z direction and spaced along the Y direction, and a top beam rod located at the top of the longitudinal uprights and extending along the Y direction. The arch top of the upper arch frame is supported on the top beam rod.

[0005] Preferably, the outer frame includes two outer uprights and two outer horizontal frames suspended between the two outer uprights. Both the outer uprights and the dividing uprights include multiple main columns extending along the Z direction and spaced apart along the Y direction.

[0006] Preferably, both the outer frame and the partition frame are equipped with an upper connecting beam and a lower connecting beam, both of which extend along the Y direction, with the upper connecting beam located above the lower connecting beam; the two ends of the upper arch rod are connected to the corresponding upper connecting beam, and the two ends of the lower arch rod are connected to the corresponding lower connecting beam.

[0007] Preferably, the longitudinal beam frame is equipped with a membrane fixing beam for fixing the lower membrane fabric, the membrane fixing beam extending along the Y direction and located below the top beam.

[0008] Preferably, the fixed membrane beam has symmetrically formed grooves on both sides, and the lower membrane fabric is divided into two side membranes, the top ends of which are fastened to the grooves on the same side by snap rings.

[0009] Preferably, the inner side of the outer frame is equipped with an inner support frame, which includes multiple inner support columns arranged at intervals along the Y direction.

[0010] Preferably, the inner support column includes a vertical section extending along the Z direction and an inclined support section located above the vertical section. The bottom of the vertical section is fixed to the ground, the inclined support section is inclined toward the corresponding outer frame, and the top of the inclined support section abuts against the lower connecting beam of the corresponding outer frame.

[0011] Preferably, the upper arch frame and the longitudinal beam frame are supported by diagonal bracing frames, which are symmetrically distributed on both sides of the longitudinal beam frame. Each diagonal bracing frame includes multiple diagonal bracing rods arranged at intervals along the Y direction.

[0012] Preferably, the outer cross frame includes multiple horizontal and vertical support rods. The horizontal support rods extend along the X direction and are spaced apart along the Z direction, and the vertical support rods extend along the Z direction and are spaced apart along the X direction. Horizontal support beams are provided vertically between adjacent outer uprights and partition uprights, and between adjacent partition uprights.

[0013] Preferably, the vertical struts extend from the ground to the upper arch frame, and at least four vertical struts at the top of each scaffold unit are fixed with diagonal braces between them and the corresponding outer frame or partition frame. The diagonal braces in the same scaffold unit are symmetrically distributed in pairs.

[0014] Compared with existing technologies, this utility model has the following technical effects: By optimizing the frame and roof structure, a single-frame double-arch structure is achieved, with the upper and lower arch frames sharing a common support frame, simplifying the greenhouse structure, reducing construction costs, and significantly reducing the distance between the upper and lower arch frames. Under the premise of maintaining the overall height of the greenhouse, the vertical space inside the greenhouse is more abundant, releasing sufficient planting and breeding space and improving the utilization rate of the greenhouse space. Through components such as external uprights, external horizontal frames, partition uprights, horizontal beams, and longitudinal beams, the entire greenhouse is connected into a spatial grid structure, improving its overall rigidity and stability. By setting diagonal braces, diagonal tie rods, and internal supports, the structural stability of the entire greenhouse is further improved. A film-fixing beam is set on the longitudinal beam frame, and symmetrical slots are designed on both sides. Combined with spring clips to fix the two side films of the lower film cloth, a standard, fast, and reliable method for installing and fixing the lower film cloth is provided.

Detailed Implementation

[0021] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0022] See Figure 1 This embodiment discloses a double-roof fully open greenhouse, which includes an outer frame. The outer frame includes two outer uprights 10 and two outer horizontal frames 20 suspended between the two outer uprights 10. Each outer upright 10 and partition upright 40 includes multiple main columns 11 extending along the Z-direction and spaced apart along the Y-direction. The outer frame is internally divided into multiple frame units by partition uprights 40, each frame unit having a roof unit at its top. The modular structure facilitates standardized production, transportation, and on-site assembly, and can be flexibly expanded as needed to adapt to different scales of planting.

[0023] See Figure 2The roof unit includes a horizontal beam frame 30, a longitudinal beam frame 32, an upper arch frame 33, and a lower arch frame 34. The horizontal beam frame 30 includes multiple horizontal beams 31 extending along the X direction and spaced apart along the Y direction. The lower arch frame 34 is positioned above the horizontal beam frame 30 and includes multiple lower arch rods 341 spaced apart along the Y direction. The upper arch frames 33 are spaced above the lower arch frames 34, and the arch tops of the upper arch frames 33 and lower arch frames 34 are aligned. The plane of the arch 34 is higher than the plane of the bottom of the upper arch frame 33. The upper arch frame 33 includes multiple upper arch rods 331 arranged at intervals along the Y direction. The longitudinal beam frame 32 is located between the upper arch frame 33 and the transverse beam frame 30. The longitudinal beam frame 32 includes multiple longitudinal uprights 321 extending along the Z direction and arranged at intervals along the Y direction, and a top beam 322 located at the top of the longitudinal uprights 321 and extending along the Y direction. The arch 33 is supported on the top beam 322. The outer upright 10 and the partition upright 40 are both equipped with upper connecting beams 51 and lower connecting beams 52. The upper connecting beams 51 and lower connecting beams 52 both extend along the Y direction, and the upper connecting beam 51 is located above the lower connecting beam 52. The two ends of the upper arch rods 331 are inserted into the corresponding upper connecting beams 51, and the two ends of the lower arch rods 341 are inserted into the corresponding lower connecting beams 52. Inserted tubes are fixed on both the upper connecting beams 51 and the lower connecting beams 52. By optimizing the frame and roof structure, a single-frame double-arch structure was achieved. The upper arch 33 and the lower arch 34 share a common support frame, which simplifies the greenhouse structure, reduces the construction cost, and effectively reduces the distance between the upper arch 33 and the lower arch 34. Under the premise that the overall height of the greenhouse remains unchanged, the vertical space inside the greenhouse is more abundant, releasing more planting space and improving the utilization rate of the greenhouse space.

[0024] The upper arch frame 33 is fitted with a waterproof and windproof upper layer of film, while the lower arch frame 34 is fitted with a heat-insulating lower layer of film. The air layer between the two layers forms an insulation layer, effectively reducing heat loss from the greenhouse in winter. It can also be opened and closed as needed to regulate the temperature and humidity inside the greenhouse, meeting the needs of different seasons and crops. See also Figure 4 To facilitate the installation of the lower membrane fabric, a membrane fixing beam 35 for fixing the lower membrane fabric is installed on the longitudinal beam frame 32. The membrane fixing beam 35 extends along the Y direction and is located below the top beam rod 322. The membrane fixing beam 35 has symmetrically formed slots 351 on both sides. The lower membrane fabric is divided into two side membrane fabrics, left and right. The top ends of the two side membrane fabrics are fastened in the slots 351 on the same side by spring clips, so that the membrane fabric can be quickly and reliably installed and removed.

[0025] A diagonal brace 36 supports the upper arch frame 33 and the longitudinal beam frame 32. The diagonal brace 36 is symmetrically distributed on both sides of the longitudinal beam frame 32, and each diagonal brace 36 includes multiple diagonal bracing rods 361 arranged at intervals along the Y direction. The diagonal bracing rods 361 between the upper arch frame 33 and the longitudinal beam frame 32 effectively resist the lateral force exerted by the upper arch frame 33 on the longitudinal beam frame 32, prevent the longitudinal beam frame 32 from tilting or bending, and improve the stability of the upper arch frame 33.

[0026] The outer horizontal frame 20 includes multiple horizontal support rods 21 and vertical support rods 22. The horizontal support rods 21 extend along the X direction and are spaced apart along the Z direction. The vertical support rods 22 extend along the Z direction and are spaced apart along the X direction. Horizontal support beams 23 are vertically installed between adjacent outer vertical frames 10 and partition vertical frames 40, and between adjacent partition vertical frames 40. Vertical support beams 24 are vertically installed between the horizontal support beams 23 and the top beam 322. The vertical support rods 22 all extend from the ground to the upper arch frame 33. Each canopy unit has four vertical support rods 22 at the top, and diagonal braces 25 are fixed between them and the corresponding outer vertical frame 10 or partition vertical frame 40. The diagonal braces 25 within the same canopy unit are symmetrically distributed in pairs. The diagonal braces 25 form a stable triangular support structure, significantly enhancing the canopy unit's ability to resist wind and snow loads. The outer horizontal frame 20 also has a doorway, into which a canopy door 26 is installed.

[0027] See Figure 3 , Figure 5 The inner side of each external support frame 10 is equipped with an inner support frame 60. The inner support frame 60 includes multiple inner support columns 61 arranged at intervals along the Y direction. Each inner support column 61 includes a vertical section 611 extending along the Z direction and a diagonal support section 612 located above the vertical section 611. The bottom of the vertical section 611 is fixed to the ground, and the diagonal support section 612 is inclined towards the corresponding external support frame 10. The top of the diagonal support section 612 abuts against the lower connecting beam 52 of the corresponding external support frame 10. A diagonal support frame 36 is supported between the upper arch frame 33 and the longitudinal beam frame 32. The diagonal support frames 36 are symmetrically distributed on both sides of the longitudinal beam frame 32. Each diagonal support frame 36 includes multiple diagonal support rods 361 arranged at intervals along the Y direction. The inner support column 61 on the inner side of the outer frame 10, especially its diagonal support section 612, effectively transfers part of the load borne by the outer frame 10, especially the load caused by external wind and snow, to the ground, thereby enhancing the greenhouse's resistance to tilting and wind and snow.
