Description

Technical Field

[0001] This invention relates to the field of marine photovoltaic technology, and more particularly to a support base for transporting marine photovoltaic platforms. Background Technology

[0002] Photovoltaic power generation is a power generation system that uses the photovoltaic effect of semiconductor materials to convert solar radiation energy into electrical energy. Offshore photovoltaic power generation is a new energy utilization and resource development method. Compared to onshore photovoltaics, it has natural environmental advantages: the open water surface is unobstructed, and there is long and fully utilized sunshine, which can significantly increase power generation. However, offshore solar photovoltaic power generation platforms, being located in open ocean waters, face more severe environmental loads than those in enclosed waters. Currently, the harsh marine environment can be mitigated by setting up platforms at sea to support the photovoltaic panels.

[0003] After the offshore photovoltaic platform is assembled on land, it is first lifted onto a transport ship using a hoisting device, and then transported to a designated location at sea. During transportation, the platform may sway on the transport ship due to wind and waves, posing a risk of capsizing. Summary of the Invention

[0023] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] The following description, with reference to the accompanying drawings, describes a support base for transporting offshore photovoltaic platforms according to an embodiment of the present invention.

[0025] like Figure 1-4 As shown in the figure, this embodiment of the invention proposes a support base for transporting offshore photovoltaic platforms, comprising: a base plate 10, an intermediate plate 7, and a placement platform 1. The base plate 10 is arranged horizontally and is suitable for detachable and fixed connection to the deck of the carrier ship. The intermediate plate 7 is arranged horizontally and has a square cross-section. The intermediate plate 7 is located above the base plate 10 and is fixedly connected to the base plate 10 by a first grid frame. Lifting points 6 are fixedly connected to the four corners of the intermediate plate 7 for lifting using a lifting device. The placement platform 1 is located above the intermediate plate 7. A limiting groove 2 is provided at the upper end of the placement platform 1. The limiting groove 2 is suitable for being inserted into the bottom of the support column. The lower end surface area of ​​the placement platform 1 is smaller than the upper end surface area of ​​the intermediate plate 7. The placement platform 1 and the intermediate plate 7 are fixedly connected by a second grid frame. The base plate 10, intermediate plate 7, placement platform 1, first grid frame, second grid frame, and lifting points 6 are all made of steel.

[0026] This embodiment of the invention provides a stable support structure for the transportation of offshore photovoltaic platforms by setting up a base plate 10, an intermediate plate 7, and a placement platform 1, ensuring greater stability during sea transport. By creating limiting grooves 2 on the placement platform 1, the support columns of the offshore photovoltaic platform can be locked into the limiting grooves 2 for restraint, concentrating the center of gravity of the support columns and preventing positional displacement during transportation, thus improving stability. By designing the base plate 10 as a structure detachably connected to the deck, the support base of this embodiment can be easily assembled and disassembled with the transport vessel, and the support base can be reused. The lower end surface area of ​​the placement platform 1 is designed to be smaller than the upper end surface area of ​​the intermediate plate 7 to allow for the installation of lifting points 6 at the edge of the intermediate plate 7, facilitating the lifting of the support base.

[0027] It should be noted that the layout of the support bases follows the layout of the support columns of the offshore photovoltaic platform, with a support base of this embodiment of the invention installed at the bottom of each support column. Since the offshore photovoltaic platform has a regular hexagonal structure, six support columns are used, and the six support columns are also distributed in a regular hexagonal pattern; therefore, the support bases are also distributed in a regular hexagonal pattern.

[0028] During use, first measure the orientation and distance of the support columns of the offshore photovoltaic platform, and then install the support seats on the deck. During lifting, insert the bottoms of the six support columns of the offshore photovoltaic platform into the limiting grooves 2 of the corresponding support seats.

[0029] Furthermore, the limiting groove 2 is a flat cylindrical structure, and the inner diameter of the limiting groove 2 is adapted to the outer diameter of the bottom of the support column.

[0030] Furthermore, the bottom plate 10 is fixedly connected to the deck by bolts.

[0031] In some embodiments, such as Figure 3 As shown, the cross-section of the placement platform 1 is square, and the center of the limiting groove 2 coincides with the center of the intermediate plate 7. This concentrates the force on the support base and improves the stability of the support.

[0032] In some embodiments, such as Figure 1 , 2 As shown, the upper surface area of ​​the intermediate plate 7 is slightly larger than the upper surface area of ​​the bottom plate 10, which can reduce the area of ​​the deck occupied by the support seat.

[0033] In some embodiments, such as Figure 1 , 2As shown in Figure 4, the first grid frame includes several first trapezoidal plates 9 and first rectangular plates 8. Both the first trapezoidal plates 9 and the first rectangular plates 8 are arranged vertically. Adjacent first trapezoidal plates 9 are parallel to each other and are fixedly connected by welding with several first rectangular plates 8. The two hypotenuses of each first trapezoidal plate 9 are located on its left and right sides, respectively. The length of the upper end face of each first trapezoidal plate 9 is shorter than the length of its lower end face. The upper end of each first trapezoidal plate 9 is fixedly connected to an intermediate plate 7, and the lower end of each first trapezoidal plate 9 is fixedly connected to a base plate 10. By welding the first trapezoidal plates 9 and the first rectangular plates 8 together, the support stability of the support base can be further improved.

[0034] In some embodiments, such as Figure 1 , 2 As shown in Figure 4, there are three first trapezoidal plates 9, and each first trapezoidal plate 9 is fixedly connected to two sides of a first rectangular plate 8. The first rectangular plate 8 and the first trapezoidal plate 9 are perpendicular to each other. By welding the first rectangular plate 8 and the first trapezoidal plate 9 perpendicularly to each other, the support stability of the support base can be further improved.

[0035] Furthermore, the first rectangular plate 8 has three rows, with four plates in each row.

[0036] In some embodiments, such as Figure 1 , 2 As shown, the second grid frame includes several second trapezoidal plates 5 and second rectangular plates 3. Both the second trapezoidal plates 5 and the second rectangular plates 3 are arranged vertically. Adjacent second trapezoidal plates 5 are parallel to each other and are fixedly connected by welding several second rectangular plates 3. The two hypotenuses of each second trapezoidal plate 5 are located on its left and right sides, respectively. The length of the upper end face of each second trapezoidal plate 5 is shorter than the length of its lower end face. The upper end of each second trapezoidal plate 5 is fixedly connected to a placement platform 1, and the lower end of each second trapezoidal plate 5 is fixedly connected to an intermediate plate 7. By welding the second trapezoidal plates 5 and the second rectangular plates 3 together, the support stability of the support base can be further improved.

[0037] In some embodiments, such as Figure 1 , 2 As shown, there are three second trapezoidal plates 5, and each second trapezoidal plate 5 has a second rectangular plate 3 fixedly connected to both sides. The second rectangular plate 3 and the second trapezoidal plate 5 are perpendicular to each other, and the projection of the second trapezoidal plate 5 in the vertical direction is perpendicular to the projection of the first trapezoidal plate 9 in the vertical direction. By perpendicularly welding the second rectangular plate 3 to the second trapezoidal plate 5 and utilizing the spatial misalignment of the first trapezoidal plate 9 and the second trapezoidal plate 5 for support, the support stability of the support base can be further improved.

[0038] Furthermore, the second rectangular plate 3 has three rows, with four plates in each row.

[0039] In some embodiments, such as Figure 1 , 2 As shown, an auxiliary support mechanism is fixedly connected between the base plate 10 and the intermediate plate 7, and the auxiliary support mechanism is located between two adjacent first trapezoidal plates 9. This can further improve the support stability of the support base.

[0040] In some embodiments, such as Figure 1 , 2 As shown, the auxiliary support mechanism includes a horizontal support plate 12 and a vertical support plate 11. The horizontal support plate 12 is fixedly connected to the upper end of the vertical support plate 11, and the horizontal support plate 12 and the vertical support plate 11 are perpendicular to each other. The vertical support plate 11 is connected to the centerline of the lower end face of the horizontal support plate 12. The upper end of the horizontal support plate 12 is fixedly connected to the lower end of the intermediate plate 7, and the vertical support plate 11 is fixedly connected to the base plate 10. This can further improve the support stability of the intermediate plate 7.

[0041] In some embodiments, such as Figure 1 , 2 As shown, a reinforcing plate 4 is fixedly connected between the placement platform 1 and the second rectangular plate 3, and the reinforcing plate 4 is located between two adjacent second trapezoidal plates 5. This can further improve the support stability of the placement platform 1.
