The box inverter needs to be placed on the box inverter platform. However, many photovoltaic projects are currently located in fish ponds, deserts, and offshore, and it is difficult to cast the box inverter platform in situ, so it is necessary to prefabricate the box inverter platform.

DETAILED DESCRIPTION

[0022] The technical solution of the utility model is described in detail below with reference to the accompanying drawings and embodiments.

[0023] like Figure 1 and Figure 2 As shown, the prefabricated box inverter platform of the utility model comprises a prefabricated platform plate 1, and a plurality of pile foundations 2 connected to the bottom of the prefabricated platform plate 1. The prefabricated platform plate 1 comprises a structural beam 11 and a structural plate 12, which are integrally formed. The bottom surface of the structural beam 11 is flush with the bottom surface of the structural plate 12; the structural beam 11 is raised relative to the top surface of the structural plate 12, and is distributed on the prefabricated platform plate 1 to form the equipment foundation.

[0024] Specifically, the structural beam of the prefabricated platform plate of the utility model serves as the equipment foundation of the box inverter, so that the platform can be better stressed and provide good and reasonable mechanical support. The bottom surface of the structural beam is flush with the bottom surface of the structural plate, which can ensure that the bottom of the prefabricated platform plate is flat, which is conducive to the connection between the prefabricated platform plate and the pile foundation, and can effectively reduce the installation difficulty caused by the pile foundation construction error, and the installation is convenient. The structural beam is turned up and used as the equipment foundation, which can also reduce the amount of materials used, which is conducive to improving material utilization and reducing costs.

[0025] In a further solution, the shape of the structural beam 1 distributed on the prefabricated platform is a rectangle with all four sides fully closed or with openings, and the shape and size of the rectangle are adapted to the equipment carried by the prefabricated box inverter platform. Since conventional box inverter equipment is often rectangular, the structural beam 1, as the equipment foundation, is formed on the platform in a rectangular shape, the size is determined by reference to the equipment requirements, and its cross section is a rectangular cross section.

[0026] In some schemes, the structural beam 11 is located in the inner area of ​​the plane of the prefabricated platform plate 1, and the peripheral area of ​​the structural beam 11 is the structural plate 12. Specifically, the structural beams are arranged around the equipment foundation to form a main frame, and the structural plates are extended from the structural beams to form a platform plate; the structural beams 11 are arranged in the middle of the prefabricated platform plate 1 to form a stable frame structure, and the structural plates 12 are extended from the structural beams 11, which can increase the platform width and save the length of the beam, thereby saving material consumption. In some schemes, the structural beams 12 are distributed on the plane of the prefabricated platform plate to form a plurality of enclosure areas, some of which are hollow, and some of which are enclosed by the structural plates 12. The setting of the hollow area is determined in combination with the actual wiring conditions of the equipment. The hollow setting facilitates the line connection of the equipment.

[0027] In addition, in some solutions, a railing foundation 6 is provided along the outer edge of the prefabricated platform plate; the railing foundation 6, the structural beam 11 and the structural plate 12 are all formed in one piece. The railing foundation further protects the platform and improves the support for the equipment.

[0028] Considering that the size of the box inverter platform is generally large, for example, the size of some box inverter platforms can reach 5m×9m. Overall prefabrication will lead to transportation difficulties. Therefore, in some solutions, the box inverter platform needs to be disassembled, transported separately, and assembled after arriving at the site. However, the existing disassembly solutions have problems such as complex disassembly, unreasonable force, inconvenient installation, large amount of on-site wet work, and high installation precision requirements.

[0029] In a preferred embodiment of the present invention, the prefabricated platform board is composed of two interconnected parts, namely, a first part 101 of the prefabricated platform board and a second part 102 of the prefabricated platform board. That is, the scheme adopts two platform boards to assemble the prefabricated box inverter platform. And the two parts of the prefabricated platform board are relatively evenly split, and each part of the prefabricated platform board has a structural beam and a structural plate, respectively, and a number of pile foundations are connected to the structural beam and the structural plate. This makes the box inverter platform structure reasonably stressed, the number of components is small, and the material consumption can be saved. In a further splitting scheme, the sides where the prefabricated platform boards of the two parts are connected include the cross-section of the structural beam and the cross-section of the structural plate. That is, the splicing of the two parts includes both the splicing between the structural beams and the splicing between the structural plates. Such a splitting scheme is simple and clear, and prefabrication and installation are convenient.

[0030] In a further solution, at least four pile foundations 2 are connected to the bottom of each part of the prefabricated platform board (prefabricated platform board first part 101, prefabricated platform board second part 102); wherein, the structural beam 11 is connected to two pile foundations, and the structural board 12 is connected to two pile foundations, and the four pile foundations 2 form four vertices of a rectangle on the plane; there are four symmetrically distributed piles under each part of the prefabricated platform board 1, which can form a stable support system, and its stability can be guaranteed when the prefabricated platform board is installed. More specifically, the two pile foundations connected to the structural beam are respectively located at the two ends of the length direction of the structural beam, and the two pile foundations connected to the structural board are located at the outer edge of the structural board. That is, the four pile foundations are arranged at the two ends of the structural beam and the outer edges of the structural board corresponding to the two ends of the structural beam. By reasonably distributing the pile foundations on the structural beam and the structural board, it can be ensured that the platform load is directly transferred to the pile foundation through the structural board and the structural beam, and the force is reasonable.

[0031] Regarding the connection between the two parts of the prefabricated platform panels, in some schemes, the sides where the two parts of the prefabricated platform panels are connected are provided with tongues and grooves and pre-embedded steel bars and steel plates. The two parts of the prefabricated platform panels are connected by connecting the steel bars, welding the steel plates and casting the tongue and groove. In some schemes, the steel bars are located in the section where the two parts of the prefabricated platform panels are connected, and the steel bars include longitudinal steel bars and transverse steel bars; the connection of the longitudinal steel bars is connected by lap welding. In some schemes, the steel plates are located on the bottom surface where the prefabricated platform panels are connected. In some schemes, the sides where the prefabricated platform panels are connected include the sections of the structural beams and the structural plates. Figure 3 As shown, it is a connection node between two parts of the structural beam 11, wherein a first reserved steel bar 31 is provided in the cross-sectional area of ​​the structural beam, a first embedded steel plate 41 is embedded in the bottom surface thereof, and a tongue and groove is left for cast-in-place fine stone concrete, i.e., the first concrete 51, during installation; a total of two rows of longitudinal steel bars (i.e., the first reserved steel bars 31) are provided on the cross-section. Since the structural beam is subjected to greater stress than other positions of the platform plate, reinforcing ribs can also be reserved at the lower end of the structural beam to enhance the stability of the connection between the two sections. A stable connection is achieved through the longitudinal connection between the steel bars, welding between the steel plates, and the tongue and groove casting. As shown Figure 4 As shown, it is a connection node between two parts of the structural plate 12, wherein the second reserved steel bar 32 of the cross section of the structural plate has a second embedded steel plate 42 embedded at its bottom surface, and a tongue and groove is left for cast-in-place fine stone concrete, i.e., the second concrete 52, during installation. Similarly, a stable connection is achieved through lap welding between the longitudinal steel bars, welding between the steel plates, and tongue and groove casting.

[0032] Based on the above scheme, for the connection between the two parts of the prefabricated platform panels, the utility model can achieve cast-in-place construction without formwork by reserving the tongue and groove, the reserved steel bars can achieve effective force transmission of the prefabricated platform panels, and the pre-buried steel plate welding can achieve equal strength connection at the joints. In addition, the connection between the prefabricated platform panels includes both the structural beams and the structural panels, and they are all connected by cast-in-place + pre-buried steel bar steel plate welding, which can achieve equal strength connection between the prefabricated platform structural beams and structural panels. Combined with the overall design and installation construction of the prefabricated platform panels, it can be seen that the solution of the utility model has a small amount of wet work on site, low installation precision requirements, and is relatively convenient to install.

[0033] For the connection between the precast platform slab and the pile foundation, some solutions, such as Figure 5 As shown, a steel plate is embedded at the place where the bottom of the prefabricated platform board 1 is connected to the pile foundation 2, namely, the third embedded steel plate 43. Thus, the bottom of the prefabricated platform board and the pile foundation are connected by welding the steel plates, forming a stable support for the prefabricated platform board, and the installation is also relatively convenient.

[0034] Based on the above schemes, it can be seen that the prefabricated box inverter platform of the utility model has the advantages of low cost, reasonable force, convenient installation, small amount of on-site wet work, simple disassembly, and low installation precision requirements.
