Description

Technical Field

[0001] The utility model relates to an offshore photovoltaic suction type steel truss structure. Background Art

[0002] Compared to onshore photovoltaic structures, offshore photovoltaic structures face the impact of wave and current loads during construction and operation, in addition to wind loads. Compared to onshore photovoltaic support foundations, offshore photovoltaic systems are primarily subject to wave and current loads. Furthermore, currently, domestic pile-based offshore photovoltaic systems are primarily located on mudflats or nearshore, where the water depth is shallow and the cover is thin. These thin cover layers often result in poor bearing capacity.

[0003] The traditional photovoltaic support structure adopts a fixed photovoltaic support structure on the upper part and photovoltaic support piles on the lower part. This connection structure is simple and economical when used for onshore photovoltaics. However, there are the following problems when used at sea: (1) In sea areas with poor surface soil bearing capacity and shallow bedrock, conventional pile foundations need to be embedded in the rock, which is costly and time-consuming; (2) The commonly used fixed photovoltaic support structures on land require a large number of pile foundations, and the cost of offshore pile foundation construction far exceeds that of onshore construction. Traditional support types cannot meet the economic requirements of marine projects; (3) The waves and currents in the marine environment are large, which easily leads to pile foundation displacement problems. At the same time, the soil in mudflats and offshore areas is relatively soft, and the pile foundation construction process is prone to large vertical displacement deviations, resulting in subsequent inability to install normally.

[0004] Therefore, to address the above problems, an offshore photovoltaic suction steel truss structure is proposed. Utility Model Content

[0005] The purpose of the utility model is to overcome the existing defects and provide an offshore photovoltaic suction steel truss structure, which is quick and convenient to construct and can adapt to the problems of thin offshore cover and poor bearing capacity.

[0006] The technical solution for achieving the above object is: an offshore photovoltaic suction steel truss structure, comprising a suction assembly and a connecting frame assembly; the upper end of the suction assembly is connected to the connecting frame assembly, the upper end of the connecting frame assembly is connected to the photovoltaic panel; the suction assembly is connected to the seabed;

[0007] The suction assembly includes four suction piles, the four suction piles are connected to the seabed, and the upper ends of the four suction piles are connected to the connecting frame assembly.

[0008] Preferably, the connecting frame assembly includes four vertical main conduits, the lower ends of the four vertical main conduits are each connected to one of the suction piles; the four vertical main conduits are each connected by a connecting steel pipe group;

[0009] The photovoltaic panel is connected to the upper steel truss, and the lower end surface of the upper steel truss is connected to four connecting rods. The lower ends of the four connecting rods are insertion sections, and the upper part of the insertion sections is connected to a partition; the insertion sections at the lower ends of the four connecting rods are respectively inserted into the four vertical main conduits.

[0010] Preferably, the four vertical main pipes are connected to the connecting steel pipe group by welding.

[0011] Preferably, the partition is connected to the upper port of the vertical main conduit by welding; and a plurality of reinforcing ribs are connected between the upper end surface of the partition and the connecting rod.

[0012] Preferably, the suction pile is an inverted cylindrical structure with a closed upper end and an open lower end.

[0013] Preferably, the suction pile is connected to the vertical main conduit by welding.

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] like Figure 1-5 As shown, an offshore photovoltaic suction steel truss structure includes a suction assembly and a connecting frame assembly. The upper end of the suction assembly is connected to the connecting frame assembly, and the upper end of the connecting frame assembly is connected to the photovoltaic panel 9. The suction assembly is connected to the seabed. The suction assembly includes four suction piles 1, which are connected to the seabed and have their upper ends connected to the connecting frame assembly. Each suction pile 1 is connected to a suction pump, and a single suction pump can also simultaneously pump multiple suction piles. The suction piles 1 are inverted cylindrical structures with a closed upper end and an open lower end.

[0024] Specifically, the connecting frame assembly includes four vertical main conduits 2, each of which is connected to a suction pile 1 at its lower end. The four vertical main conduits 2 are each connected by a connecting steel pipe group 3. The four vertical main conduits 2 are welded to the connecting steel pipe group 3. The suction piles 1 are welded to the vertical main conduits 2.

[0025] Specifically, the photovoltaic panel 9 is connected to the upper steel truss 4, and the lower end surface of the upper steel truss 4 is connected to four connecting rods 5. The lower ends of the four connecting rods 5 are insertion sections 6, and the partitions 7 are connected above the insertion sections 6; the insertion sections 6 at the lower ends of the four connecting rods 5 are respectively inserted into the four vertical main conduits 2.

[0026] Specifically, the partition plate 7 is connected to the upper end of the vertical main conduit 2 by welding; a plurality of reinforcing rib plates 8 are connected between the upper end surface of the partition plate 7 and the connecting rod 5 .

[0027] Specifically, suction piles 1, vertical main conduits 2, and connecting steel pipes 3 are prefabricated in advance at an onshore factory. A suction pile 1 is welded to the lower ends of each of the four vertical main conduits 2, and the four vertical main conduits 2 are then connected to each other via the connecting steel pipe 3. The upper steel trusses 4, connecting rods 5, partitions 7, and photovoltaic panels 9 are prefabricated in advance at an onshore factory. The upper ends of the upper steel trusses 4 are connected to the photovoltaic panels 9, and four connecting rods 5 are welded to the lower end faces of the upper steel trusses 4. A partition 7 is connected above the insertion sections 6 at the lower ends of the connecting rods 5, and multiple reinforcing ribs 8 are connected between the upper ends of the partitions 7 and the connecting rods 5. The welded components are transported as a whole to the offshore construction site. The hoisting components are used to sink the four suction piles 1. During the sinking process, the foundation is leveled by adjusting the suction pump power. The hoisting components insert the insertion sections 6 at the lower ends of the four connecting rods 5 into the four vertical main conduits 2. The upper end of each vertical main conduit 2 is welded to the partition plate 7 to achieve an integral connection.

[0028] The suction foundation construction adopted in this offshore photovoltaic suction steel truss structure is fast and convenient, and can well adapt to problems such as thin offshore cover and poor bearing capacity; the pile foundations are connected by steel pipes to form a whole before installation, avoiding the problem of displacement between pile foundations during construction, which may cause the upper steel truss to be unable to be installed smoothly; at the same time, the upper steel truss is a whole, and the photovoltaic panels can be pre-installed on the steel truss on land and then hoisted in a unified manner, reducing the offshore construction and installation process.
