[0033] As shown in the drawings, Figures 1-3 The pile foundation ladder structure of offshore photovoltaic includes a pile 1, a ladder 2, and a guardrail 3. The pile 1 is fixed on the sea surface and is used to support the offshore platform. The ladder 2 extends along the extension direction of the pile 1 and is fixed on the pile 1. At least part of the ladder 2 is located on the sea surface. The guardrail 3 is fixed on the ladder 2 and extends along the extension direction of the ladder 2. A climbing channel is formed between the guardrail 3 and the ladder 2. The guardrail 3 includes a plurality of surrounding parts 31 and a plurality of vertical ribs 32. The surrounding parts 31 are distributed at intervals along the extension direction of the ladder 2. The surrounding part 31 includes two oppositely arranged first guard parts 311 and a second guard part 312 connected between the two first guard parts 311. The two first guard parts 311 are respectively fixed on both sides of the ladder 2 in a first direction X, and the first direction intersects the extension direction of the ladder 2. The vertical ribs 32 extend along the extension direction of the ladder 2 and are connected to the surrounding parts 31 to form a grid structure with the surrounding parts 31.
[0034] The pile foundation ladder structure of offshore photovoltaic provided by the example embodiment has the following advantages. On the one hand, workers can enter and exit the offshore platform through the ladder. On the other hand, the guardrail corresponding to the ladder 2 is arranged on the pile foundation ladder structure of offshore photovoltaic. The guardrail can better protect the workers to avoid falling into the sea. At the same time, the guardrail can also assist the workers in climbing the ladder.
[0035] In the example embodiment, the offshore platform includes a box transformer support assembly for supporting a box transformer substation.
[0036] In the example embodiment, as shown in the drawings, Figures 1-3 At least part of the vertical ribs 32 are respectively connected to the two first guard parts 311, and at least part of the vertical ribs 32 are connected to the second guard part 312. This arrangement can make the surrounding parts 31 form a grid structure with the vertical ribs 32 at each position. The guardrail 3 with the grid structure has better protection and is convenient for workers to climb.
[0037] In the example embodiment, as shown in the drawings, Figures 1-3 The vertical ribs 32 are fixed to the inner side of the surrounding part 31. The vertical ribs 32 have a relatively long length and weak strength. In the example embodiment, the vertical ribs 32 are fixed to the inner side of the surrounding part 31. When the vertical ribs 32 are subjected to an outward pulling force, the surrounding part 31 can support the vertical ribs 32, thereby improving the overall strength of the guardrail 3.
[0038] In the example embodiment, as shown in the drawings, Figures 1-3As shown, the second guard part 312 is an outwardly convex arc structure. The outwardly convex arc structure can form a larger space in the crawling channel, and the arc structure has a relatively smooth surface, thereby reducing the risk of the staff knocking into the guardrail 3.
[0039] In the present exemplary embodiment, as shown in Figures 1-3 The offshore photovoltaic pile ladder structure further comprises a hoop 4 and an I-shaped connecting part 5. The hoop 4 is fixed to the pile 1, and the I-shaped connecting part 5 is fixed between the hoop 4 and the ladder 2. The I-shaped connecting part 5 is fixed to both ends of the ladder 2 in the first direction X. The hoop 4 and the I-shaped connecting part 5 can more stably fix the ladder to the pile 1.
[0040] In the present exemplary embodiment, as shown in Figures 1-3 The top of the guardrail 3 can be lower than the top of the ladder 2. This arrangement can facilitate the staff to enter and exit from the crawling channel.
[0041] In the present exemplary embodiment, as shown in Figures 1-3 The bottom of the guardrail 3 can be higher than the bottom end of the ladder 2. This arrangement can also facilitate the staff to enter and exit from the crawling channel.
[0042] In the present exemplary embodiment, as shown in Figures 1-3 The plurality of surrounding parts 31 are distributed at equal intervals. The surrounding parts 31 and the vertical ribs 32 can form a relatively stable grid structure. It should be understood that in other exemplary embodiments, the surrounding parts 31 can also be arranged at unequal intervals. For example, the interval between adjacent surrounding parts 31 at the top and bottom positions of the guardrail 3 can be smaller than the interval between adjacent surrounding parts 31 at the middle position of the guardrail 3. When climbing the ladder, the staff usually uses the top and bottom positions of the guardrail 3 as auxiliary climbing support points. Therefore, the interval between adjacent surrounding parts 31 at the top and bottom positions of the guardrail 3 can be correspondingly set to be smaller.
[0043] In the present exemplary embodiment, as shown in Figures 1-3As shown, the ratio of the distance between adjacent encircling parts 31 and the size of the ladder 2 in its extension direction is 1 / 45-1 / 15, for example, the ratio of the distance between adjacent encircling parts 31 and the size of the ladder 2 in its extension direction can be equal to 1 / 45, 1 / 40, 1 / 35, 1 / 30, 1 / 25, 1 / 20, 1 / 15, etc. If the ratio of the distance between adjacent encircling parts 31 and the size of the ladder 2 in its extension direction is too small, the distance between adjacent encircling parts 31 is too small, the weight of the guardrail 3 is heavy, thereby causing a large load on the pile 1; if the ratio of the distance between adjacent encircling parts 31 and the size of the ladder 2 in its extension direction is too large, the distance between adjacent encircling parts 31 is too large, the mesh of the guardrail 3 is large, and the protection effect of the guardrail 3 on the workers is weak. The exemplary embodiment sets the ratio of the distance between adjacent encircling parts 31 and the size of the ladder 2 in its extension direction to an appropriate size, which can not only reduce the load of the pile 1, but also improve the protection effect of the guardrail 3.

This application is intended to cover any variations, uses or adaptations of the disclosure other than those expressly disclosed herein.
