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

[0024] The wiring device for offshore photovoltaics according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0025] like Figure 1-4 As shown, an embodiment of the present invention proposes a wiring device for offshore photovoltaics, including: a guide rod 8, a support plate 15, a wire trough 10 and a horizontal tightening mechanism, wherein the guide rod 8 is arranged in the vertical direction, the guide rod 8 is cylindrical, and the guide rod 8 is provided with at least two, and the upper end of the guide rod 8 is fixedly connected to the bottom of the support beam 1; the support plate 15 is arranged in the horizontal direction, the support plate 15 is arranged at the bottom of the support beam 1, the guide rod 8 is arranged on one side of the support plate 15, the support plate 15 and the guide rod 8 are slidably matched, the support plate 15 slides in the vertical direction and is locked and positioned by a locking device; the wire trough 10 is placed on the support plate 15 and is located between the support plate 15 and the support beam 1, and the wire trough 10 is suitable for placing cables; the horizontal tightening mechanism is slidably connected to the top of the support plate 15, the wire trough 10 is located between the guide rod 8 and the horizontal tightening mechanism, the horizontal tightening mechanism tightens the wire trough 10 to the guide rod 8 through a sliding action, and the horizontal tightening mechanism is fixedly connected to the support plate 15 by a first bolt 5.

[0026] The embodiment of the present invention protects the cables by placing the cables into the cable trough 10 and pressing the cable trough 10 through the guide rod 8, the support plate 15 and the horizontal tightening mechanism, thereby preventing the cables from jumping out of the cable trough 10 when the offshore photovoltaic platform floats on the sea, thereby increasing the risk of cable damage.

[0027] It should be noted that the support beam 1 is used to install solar panels, and the cables of the solar panels are routed at the bottom of the support beam 1. In actual use, each wire trough 10 is supported by multiple wiring devices of the embodiments of the present invention, and the number and installation position of the wiring devices can be designed according to actual needs.

[0028] Furthermore, the cable duct 10 is made of channel steel and has a U-shaped longitudinal section, and the cables pass through the front and rear ends of the cable duct 10 .

[0029] In some embodiments, Figure 1 , 2 As shown, the locking device includes second bolts 3 located at the four corners of the support plate 15. The second bolts 3 suspend the support plate 15 from the bottom of the support plate 15 to the bottom of the support beam 1 from bottom to top. The bottom of the support beam 1 is fixed with a nut 2, and the second bolts 3 are threadedly matched with the nut 2.

[0030] Furthermore, the second bolt 3 is a long bolt, and the length of the threaded portion of the second bolt 3 is greater than the height of the wire groove 10, so as to ensure that the second bolt 3 can be fixed on the support beam 1. The nut of the second bolt 3 plays a role in limiting the support plate 15 in the vertical direction, preventing the support plate 15 from sliding downward.

[0031] In some embodiments, Figure 1 , 3 As shown, the horizontal tightening mechanism includes a vertical plate 4 and a horizontal plate 6. The vertical plate 4 and the horizontal plate 6 are perpendicular to each other and fixedly connected to form an L-shaped structure. The horizontal plate 6 is arranged at the upper end of the support plate 15 and fits with the support plate 15. When the vertical plate 4 tightens the wire trough 10, the horizontal plate 6 is fixedly connected to the support plate 15 by the first bolt 5. There are several first bolts 5 and they are evenly distributed on the horizontal plate 6.

[0032] Furthermore, a slideway may be provided on the upper end surface of the support plate 15 , and the horizontal plate 6 slides on the slideway in a direction toward or away from the wire trough 10 .

[0033] In some embodiments, Figure 1 , 2 As shown, the first buffer pad 9 is connected to the contact surface of the cable trough 10 with the guide rod 8, and the second buffer pad 14 is connected to the contact surface of the cable trough 10 with the vertical plate 4. The horizontal tightening mechanism can tighten the cable trough 10 in the horizontal direction to prevent the cable trough 10 from shaking left and right and hitting surrounding components when floating on the sea.

[0034] In some embodiments, Figure 1 , 2 As shown, the third buffer pad 7 is connected to the contact surface between the support beam 1 and the cable trough 10. It is convenient to tighten the cable trough 10 in the vertical direction to prevent the cable trough 10 from shaking up and down and hitting the support beam 1 when floating on the sea.

[0035] It should be noted that, since the wire duct 10 is in a U-shaped structure, two third buffer pads 7 are provided for each wire duct 10 .

[0036] In some embodiments, Figure 1 ,2 As shown, the third buffer pad 7 is fixedly connected to the upper end surface of the wire trough 10 .

[0037] In some embodiments, a plurality of spring plates are evenly connected to the bottom of the cable trough 10 to support the cables placed in the cable trough 10. This allows the cables to be separated from the bottom of the cable trough 10, and prevents the seawater entering the cable trough 10 from staying in the cable trough 10 for a long time and causing immersion and corrosion to the cables.

[0038] In some embodiments, Figure 1 , 4 As shown, the spring plate includes a plate body 13, a sleeve 12, a telescopic tube 11 and a spring 16. The spring 16 is connected between the bottom of the wire trough 10 and the plate body 13. Four springs 16 are provided and are respectively provided at the four corners of the plate body 13. The outside of each spring 16 is respectively sleeved with a sleeve 12 and a telescopic tube 11. The sleeve 12 is fixedly connected to the bottom of the wire trough 10. The telescopic tube 11 is slidably connected to the upper end of the sleeve 12. The upper end of the telescopic tube 11 is fixedly connected to the plate body 13. The upper and lower ends of the spring 16 are respectively fixedly connected to the plate body 13 and the bottom of the wire trough 10.

[0039] By providing the sleeve 12 and the telescopic tube 11, the spring 16 can be extended and retracted along a fixed direction, and the spring 16 can also be protected to prevent the spring 16 from being corroded by seawater and rusting.

[0040] It should be noted that the sleeve 12 and the telescopic tube 11 form a telescopic structure, and a limiting structure is provided at the joint of the sleeve 12 and the telescopic tube 11 so that the telescopic tube 11 will not separate from the sleeve 12 when moving.

[0041] In some embodiments, a plurality of leakage holes are provided at the bottom of the cable trough 10 , and the leakage holes are provided between two adjacent support plates 15 , so as to discharge the seawater entering the cable trough 10 in time.

[0042] In some embodiments, the guide rod 8, the support plate 15, the wire trough 10, and the horizontal tightening mechanism are all coated with seawater-resistant anticorrosive paint, which can improve the seawater corrosion resistance of the overall device.
