[0008] Optionally, the lower chord at the column is provided with a longitudinal rib that is perpendicular to the column and the lower chord and passes through the column and the lower chord.

[0009] Optionally, the top support frame is a wave-shaped support frame composed of triangular frames, with the bottom of the triangular frames connected to the top of the upper chord, and the triangular frames perpendicular to the upper chord along the length direction. That is, each triangular frame spans multiple upper chords, and multiple steel support rods connecting the top and bottom of the triangular frames are evenly provided on both sides of the triangular frames.

[0017] The following combination Figure 1 The present invention will be described in further detail below.

[0018] This invention discloses an array-type wave-shaped photovoltaic greenhouse truss structure, with reference to Figure 1 It includes a truss 1, a column 2 and a top support frame 3. The column 2 is set vertically, and the truss 1 is set at the top of the column 2 perpendicular to the column 2. The top support frame 3 is connected to the top of the truss 1. A multi-directional support block 4 is provided on the column 2 below the truss 1. The multi-directional support block 4 is provided with a ring-shaped hanging ring. A multi-directional cable 5 is provided on the hanging ring. The other end of the multi-directional cable 5 is connected to the top support frame 3.

[0019] In a further embodiment, the truss 1 includes an upper chord 11 and a lower chord 12. The upper chord 11 is located at the top of the column 2, and the lower chord 12 is located below the upper chord 11. Multiple triangular support frames 13 are connected to one side of the upper chord 11 and the lower chord 12. The triangular support frame 13 is a hollow sleeve with an anti-bending spring inside. The triangular support frame 13 can resist the moment generated by the lateral wind load on the greenhouse structure, enhance dynamic stability, and avoid structural deformation under strong wind conditions. The lower chord 12 at the column 2 is provided with longitudinal ribs 6 that are perpendicular to the column 2 and the lower chord 12 and pass through the column 2 and the lower chord 12.

[0020] In a further embodiment, the top support frame 3 is a wave-shaped support frame composed of triangular frames, the bottom of which is connected to the top of the upper chord 11, and the triangular frames are perpendicular to the upper chord 11 along their length. That is, each triangular frame spans multiple upper chords 11. Multiple steel support rods 31 are evenly provided on both sides of the triangular frame to connect the top and bottom of the triangular frame. The steel support rods 31 are hollow sleeves with anti-bending springs inside. The top of the triangular frame of the top support frame 3 is provided with cross cables 32, and the lower end of the cross cables 32 is connected to two adjacent upper chords 11, thereby reducing the wind vibration effect.

[0021] Specifically, the truss 1 at the connection between the triangular frame and the truss 1 adopts a thickened steel plate or reinforcing rib design to distribute the concentrated load, promote node strengthening and local stress optimization. The design of the wave-shaped support frame can optimize the angle of reception of incident light by the photovoltaic panel, solving the problem of low light utilization rate of fixed brackets.

[0022] The column 2 and truss 1 in this utility model are modularly designed. The smallest unit is a column 2 and a section of truss 1 on it. The truss 1 is pre-designed to a suitable length. When building the greenhouse, the column 2 is first positioned, and then the truss 1 on it is connected with bolts or clamps to form a large greenhouse frame. Then, the top support frame 3 is connected above the truss 1, and then the cross cable 32 is installed. Finally, according to the local climate and other characteristics, the multi-directional cable 5 is fixed at a suitable position on the top support frame 3 to improve the resistance to wind, snow and earthquakes. Then, photovoltaic panels are installed in the top support frame 3.

[0023] This utility model adopts a modular unit design, forming a large-space greenhouse main structure through standardized truss assembly. The main body is made of hot-dip galvanized square tube and Q235 carbon steel or lightweight corrosion-resistant materials (such as aluminum alloy and fiberglass) to improve the corrosion resistance of the main body. The resistance to wind and snow loads is improved through triangular truss support and node reinforcement technology. The photovoltaic panel load is evenly distributed to the floating body or foundation by designing multiple columns 2, which improves the overall bending performance. Moreover, the truss structure of this utility model achieves a larger span and lower material consumption.
