Detailed Description
1. Basic structure
As shown in fig. 1 to 3, the ecological forestry photovoltaic greenhouse comprises a main body and a roof, wherein the main body is formed by adopting a multi-span photovoltaic supporting structure system, the roof is formed by splicing and installing photovoltaic plates 1 serving as roof plates, and frame frames of the photovoltaic plates are fixed with steel purlines 2 through bolts; the transverse splice 3 between the photovoltaic panels on the roof uses a transverse waterproof device, and the longitudinal splice 4 between the photovoltaic panels on the roof uses a longitudinal waterproof device. Wherein,
each multi-span photovoltaic support structure system mainly comprises a cuboid frame, wherein the cuboid frame is composed of four steel upright posts 5, the lower ends of the steel upright posts are connected with screw piles 6 through foot bottom plates, the front two steel upright posts and the rear two steel upright posts are respectively connected through longitudinal truss joists, and the left end and the right end of each longitudinal truss joist are respectively fixed at the upper ends of the steel upright posts through welding; a herringbone girder 7 is welded between the longitudinal truss joists, the top ends of the herringbone girders are connected with bolts through ridge tie bars 8, and the steel purlines are fixedly connected with the upper flanges of the herringbone girders through bolts; the longitudinal truss joist comprises an upper chord 9, a lower chord 11 and a web member 10, wherein the herringbone steel beam is fixed on the upper chord of the longitudinal truss joist through welding, and two ends of the upper chord and the lower chord are respectively fixed on the top and the middle upper part of the steel column. The herringbone steel beam consists of two high-frequency thin-wall H-shaped steel.

2. Construction use
The spiral pile foundation is constructed first, the spiral pile is taken as the foundation of the system, and the spiral pile is deep into soil for about 2m, so that the construction is simple, the ground surface damage is less, the construction cost is low, the environment is protected, and the installation is convenient. After the steel upright post is connected with the spiral pile foundation, the vertical force and the horizontal force born by the whole system are transferred to the soil body. The steel upright posts are fixed on the top surface of the foundation, and the left end and the right end of the longitudinal truss joist are respectively fixed on the steel upright posts on the two sides through welding. The herringbone steel beam is fixed on an upper chord member of the longitudinal truss joist through welding, and the steel purline is fixed on an upper flange of the herringbone steel beam through bolt connection; the frame of the photovoltaic panel is fixed with the steel purline through bolts, so that a supporting structure of the photovoltaic roof panel is formed. The upper chord member and the lower chord member are continuous rod members, are stretch bending members, and are suitable for large-space structures with larger column pitches. Compared with the traditional steel roof truss, the connecting nodes are fewer, and the construction is convenient.
According to actual needs, the size of the greenhouse main body can be adjusted, and one or more multi-span photovoltaic support structure systems can be adopted for forming the greenhouse main body. The illustrated greenhouse body adopts four multi-span photovoltaic support structure systems to form a two-row two-column structure, each row is connected end to end, and each column is connected front to back.
The structural truss has a large span adaptation range, and solves the problem of large space required by a wood sunning ground. Meanwhile, the span of the purline is reduced to half of the original span by adding the herringbone beam of the middle support, so that the section size of the purline can be reduced. Compared with the truss-free scheme, the truss-free scheme has the advantages that the steel consumption is reduced by 29.67t/MWp, and the construction cost is saved by about 15 ten thousand yuan/MWp.
The lower space of the supporting structure system is wide for placing the airing rack 14 to air the wood, and the periphery of the supporting structure system is not required to be provided with an enclosure structure; the photovoltaic module is adopted at the upper part of the structure, and is directly adopted as a roof Board (BIPV), so that the cost of the roof profiled steel sheet is saved. Specifically, the photovoltaic big-arch shelter roof is installed by photovoltaic board concatenation and is formed, and the roofing is indulged transversely and all has the splice. The transverse splice seam is parallel to the roof drainage direction (parallel to the span direction of the bracket), the water flow permeation effect is small, the joint seam is blocked by adopting a sealing rubber strip, and the construction is simple and quick; the longitudinal splicing seam is perpendicular to the roof drainage direction (perpendicular to the span direction of the support), a through-length PVC drainage groove (called gutter for short) is arranged below the longitudinal splicing seam, and downpipes are arranged at intervals along the gutter, so that roof rainwater collected in the gutter can be timely drained to the ground drainage ditch, and the requirements of waterproof and organized drainage of the roof of the photovoltaic greenhouse are met.
The gutter can adopt commercial complete products, and the end sealing plates, the splicing connectors and the water falling hopper are all standard fittings, so that the gutter is rapid and convenient to install and has low requirements on skills of constructors; the gutter does not have the requirement on the uniformity of the gap width of the longitudinal splice seam of the photovoltaic panel and the flatness of the photovoltaic panel, people do not need to be on the roof during construction and in later-stage replacement and maintenance of the photovoltaic panel, and the operation of the photovoltaic panel is not influenced by the later-stage replacement and maintenance of the gutter.
