Specifically, the first-layer arched frame 1 can form an indoor space above the ground, and the outer surface of the first-layer arched frame 1 refers to the side of the first-layer arched frame 1 facing away from the indoor space. Similarly, the outer surface of the truss 3 refers to the side of the truss 3 facing away from the indoor space.

[0036] In this embodiment, the first-layer arched frame 1, the truss 3, and the second-layer arched frame 2 form a three-layer support structure. Among them, the first-layer arched frame 1 and the second-layer arched frame 2 play a supporting role.

[0037] Implementing the support structure provided in this embodiment has at least the following beneficial technical effects:

[0038] The truss 3 covers the outer surface of the first-layer arched frame 1, and the second-layer arched frame 2 covers the outer surface of the truss 3. The first-layer arched frame 1 and the second-layer arched frame 2, which are respectively inside and outside the support structure, both adopt an arched structure.

Moreover, the truss 3 fills the space between the first-layer arched frame 1 and the second-layer arched frame 2. The truss 3 can significantly strengthen the support structure, improving the wind resistance and compressive resistance of the support structure.

[0039] Please refer to Figures 1 to 6 and Figure 11 In an embodiment of the present application, the first-layer arched frame 1 includes a plurality of first connecting rods 11, the second-layer arched frame 2 includes a plurality of second connecting rods 21, and the truss 3 includes a plurality of third connecting rods 31. Each of the first connecting rods 11 is connected to form a plurality of spliced triangular frames; or, each of the second connecting rods 21 is connected to form a plurality of spliced triangular frames; or, each of the first connecting rods 11 is connected to form a plurality of spliced triangular frames, and each of the second connecting rods 21 is connected to form a plurality of spliced triangular frames. One end of the third connecting rod 31 is connected to the first-layer arched frame 1, and the other end of the third connecting rod 31 is connected to the second-layer arched frame 2. The third connecting rod 31 forms a plurality of spliced conical frames between the first-layer arched frame 1 and the second-layer arched frame 2.

[0040] At least one of the first-layer arched frame 1 and the second-layer arched frame 2 adopts a triangular support structure. By using the characteristic that the triangular support structure is not easily deformed, the support structure has excellent stability. Preferably, both ends of the third connecting rod 31 are respectively connected to the end of the first connecting rod 11 and the end of the second connecting rod 21, reducing the number of connection points of the entire support structure, reducing costs, simplifying installation, and being able to optimize the stability of the support structure, improving the wind resistance and compressive resistance of the support structure.

[0041] As a specific solution of this embodiment, the first connecting rod 11, the second connecting rod 21, and the third connecting rod 31 all adopt carbon steel pipes of six-point or one-inch specifications, and the first connecting rod 11, the second connecting rod 21, and the third connecting rod 31 are connected by 10.9-grade bolts or 10.9-grade screws. In this way, the average load of each connection point of the support structure can reach more than 180 kilograms. The greenhouse with the support structure provided in this embodiment can resist strong winds above level 12, and for strong winds in any direction, it has the smallest windward surface and has extremely strong compressive and wind resistance.

[0042] Please refer to Figure 7, in an embodiment of the present application, the first-layer arched frame 1 includes a plurality of first connecting rods 11, the second-layer arched frame 2 includes a plurality of second connecting rods 21, and the truss 3 includes a plurality of third connecting rods 31; each of the second connecting rods 21 is connected to form a plurality of spliced triangular frames, and each of the first connecting rods 11 is connected to form a plurality of spliced polygonal frames; the support structure further includes a reinforcing-layer frame, and the reinforcing-layer frame includes a plurality of fourth connecting rods. Both ends of each fourth connecting rod are connected to the end of the first connecting rod 11 (alternatively, one end of the fourth connecting rod is connected to the end of the first connecting rod 11, and the other end of the fourth connecting rod is connected to the end of an adjacent fourth connecting rod to form a support structure inside the triangle when the first connecting rods 11 have already formed a triangle), and each of the fourth connecting rods is connected to form a plurality of spliced triangular frames; one end of the third connecting rod 31 is connected to the first-layer arched frame 1, and the other end of the third connecting rod 31 is connected to the second-layer arched frame 2. The third connecting rod 31 forms a plurality of spliced conical frames between the first-layer arched frame 1 and the second-layer arched frame 2.

[0043] In this embodiment, the support structure adopts a four-layer frame structure including the triangular second-layer arched frame 2, the truss 3, the polygonal first-layer arched frame 1, and the triangular reinforcing-layer frame, which can further optimize the stability of the support structure and improve the wind resistance and compressive resistance of the support structure.

[0044] Please refer to Figure 11 , in an embodiment of the present application, the first connecting rod 11 includes a first rod-shaped portion 111 and first wedge-shaped connecting portions 112 provided at both ends of the first rod-shaped portion 111. The first wedge-shaped connecting portion 112 is provided with a first connection hole 113; the support structure further includes a threaded connector 6 passing through the first connection hole 113, and the threaded connector 6 is used to connect adjacent first connecting rods 11.

[0045] As a specific solution of this embodiment, the second connecting rod 21 includes a second rod-shaped portion 211 and second wedge-shaped connecting portions 212 provided at both ends of the second rod-shaped portion 211. The second wedge-shaped connecting portion 212 is provided with a second connection hole 213; the third connecting rod 31 includes a third rod-shaped portion 311 and third wedge-shaped connecting portions 312 provided at both ends of the third rod-shaped portion 311. The third wedge-shaped connecting portion 312 is provided with a third connection hole 313. At the connection points between the first connecting rods 11, the threaded connector 6 passes through the first connection hole 113 and the third connection hole 313 of the third connecting rod 31 corresponding to this node to realize the connection between the plurality of first connecting rods 11 and the plurality of third connecting rods 31; at the connection points between the second connecting rods 21, the threaded connector 6 passes through the second connection hole 213 and the third connection hole 313 of the third connecting rod 31 corresponding to this node to realize the connection between the plurality of second connecting rods 21 and the plurality of third connecting rods 31.

[0046] In this way, the assembly and connection of the first-layer arched frame 1, the assembly and connection of the second-layer arched frame 2, the connection between the truss 3 and the first-layer arched frame 1, and the connection between the truss 3 and the second-layer arched frame 2 can be realized. Moreover, compared with the traditional connection methods using connection balls or welding, the use of threaded connectors 6 to connect the first-layer arched frame 1, the truss 3, and the second-layer arched frame 2 can effectively reduce the installation time at each connection node, and the machining accuracy requirements for each connection node are low, thereby reducing the installation cost at the connection nodes. Each first connecting rod 11, second connecting rod 21, and third connecting rod 31 can be made by stamping a steel pipe and then opening holes, which greatly reduces the manufacturing cost of the support structure. At the same time, the use of threaded connectors 6 to connect the first connecting rod 11, second connecting rod 21, and third connecting rod 31 can ensure the connection stability. By using a screw or bolt made of 10.9-grade carbon steel and the first connecting rod 11, second connecting rod 21, and third connecting rod 31 made of one-sixth-inch carbon steel pipe, the average load of the connection node can reach up to 180 kg.

[0047] As a specific solution of this embodiment, when the support structure adopts a four-layer frame structure including a triangular second-layer arched frame 2, a truss 3, a polygonal first-layer arched frame 1, and a triangular strengthening layer frame, each fourth connecting rod of the strengthening layer frame includes a fourth rod-shaped portion and fourth wedge-shaped connecting portions provided at both ends of the fourth rod-shaped portion. The fourth wedge-shaped connecting portion is provided with a fourth connection hole, and the fourth connecting rod and the second connecting rod 21 are also connected by a threaded connector 6. Using the threaded connector 6 for connection can also achieve the technical effects of low manufacturing cost, convenient installation, and high connection strength.

The curtain includes a main curtain for covering the second-layer arched frame 2 and a top curtain for covering the ventilation window frame 52. A notch is provided at the position of the main curtain corresponding to the ventilation window assembly 5 to facilitate the installation of the ventilation window assembly 5; the ventilation window assembly 5 can be connected to the side of the second-layer arched frame 2 facing away from the first-layer arched frame 1, and the ventilation window 53 is not covered by the curtain to realize the ventilation and air exchange of the greenhouse.

[0050] The advantage of setting the ventilation window assembly 5 at the top of the second-layer arched frame 2 is that it can effectively utilize the heat accumulation effect at the top of the greenhouse to enhance the ventilation effect of the ventilation window assembly 5. Specifically, the density of hot air is lower than that of cold air. Inside the greenhouse, hot air will gather at the top of the greenhouse, and the external air flow speed at the top of the greenhouse is fast and the pressure is low. By opening a ventilation window 53 at the top of the greenhouse and setting the corresponding ventilation window assembly 5, hot air can continuously flow out from the top of the greenhouse, thereby improving the efficiency of greenhouse ventilation and cooling.

[0051] It is worth mentioning that the first-layer arched frame 1, the second-layer arched frame 2, and the truss 3 are all complete shell-shaped structures without notches; that is, at the position of the first-layer arched frame 1 opposite to the ventilation window assembly 5, there is still a triangular frame or a polygonal frame formed by connecting the first connecting rods 11, at the position of the second-layer arched frame 2 opposite to the ventilation window assembly 5, there is still a triangular frame formed by connecting the second connecting rods 21, and at the position of the truss 3 opposite to the ventilation window assembly 5, there is still a conical frame formed by connecting the third connecting rods 31 to strengthen the strength of the support structure, so that the ventilation window assembly 5 can be further connected and installed with automation equipment such as fans and hydraulics.

This can minimize the windward area of the support structure, avoid damage to the ventilation window 53, and at the same time prevent rain, snow, etc. from falling into the internal space of the support structure when the ventilation window 53 is opened for ventilation.
