Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of offshore photovoltaic auxiliary tooling, in particular, to a climbing ladder structure for offshore photovoltaic construction operation. BACKGROUND

[0002] Photovoltaic is a device that converts solar energy into electrical energy. Due to the cleanliness and convenience of solar energy, the development and use of photovoltaic projects have a wide range of application scenarios. A photovoltaic project usually includes a large number of photovoltaic structures, which can include photovoltaic supports, multiple photovoltaic panels, and cable components. The photovoltaic panels are laid on the photovoltaic supports, and the installation and maintenance of each component require the assistance of workers. Therefore, a climbing ladder structure is needed to assist workers in installing and maintaining photovoltaic components.

[0003] Currently, for photovoltaic projects on the sea, the structure of each component is relatively complex and bulky. After the preliminary hoisting of each component, manual fine installation and adjustment are required. Therefore, a climbing ladder structure is needed to provide support for the operator at the corresponding position. However, due to the presence of many unsafe factors on the sea, the stability and convenience of the climbing ladder structure are required to be higher. The commonly used climbing ladder cannot meet the requirements of stability and convenience of the climbing ladder structure for offshore construction operation.

[0004] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present disclosure, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art.

However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0033] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0034] In related technologies, the upper support structure of offshore photovoltaic projects is relatively complex. It typically involves initial assembly on land, followed by sea transportation and hoisting. Then, manual labor is used to refine and adjust the upper support structure to ensure it meets engineering requirements. Further detailed installation and adjustment of photovoltaic modules are unavoidable. Therefore, providing a stable support structure that allows personnel to easily climb to predetermined positions on the upper support structure for operation is a crucial problem that needs to be solved.

[0035] Based on this, the present disclosure provides a ladder structure for offshore photovoltaic construction operations, such as... Figure 1 As shown, combined with Figures 2 to 5 The ladder structure includes: a first support component 10, a second support component 20, and a step assembly 30.

[0036] The first support assembly 10 includes a main body 11, which includes a first support rod 101 and a second support rod 102 arranged opposite to each other. Multiple connecting rods 103 connect the first support rod 101 and the second support rod 102. Limiting members 12 are respectively provided at both ends of the main body 11. The first support assembly 10 is detachably connected to the rods in the upper support structure via the limiting members 12. The pedal assembly 30 is arranged opposite to the first support assembly 10 and has a flat plate structure. The first surface 31 of the pedal assembly 30 is used to provide support force. The side facing away from the first support assembly 10; the second support assembly 20 connects the first support assembly 10 and the pedal assembly 30. The second support assembly 20 includes a first connector 201, a second connector 202, a third connector 203, and a fourth connector 204 arranged perpendicular to the first support rod 101 and extending in the same direction. The first connector 201 and the second connector 202 are spaced apart and connected to the first support rod 101. The third connector 203 and the fourth connector 204 are spaced apart and connected to the second support rod 102. A reinforcing assembly 40 is provided between two adjacent connectors.

[0037] The ladder structure for offshore photovoltaic construction provided in this disclosure is an I-shaped structure formed by the interconnection of the footplate assembly 30, the second support assembly 20, and the first support assembly 10. A reinforcing assembly 40 is provided between two adjacent connecting parts to improve the overall structural stability and provide effective support force and reliable support position. The two ends of the main body 11 of the first support assembly 10 are detachably connected to the upper support structure of the offshore photovoltaic through limiting members 12, so that the ladder structure can meet the construction needs of multiple positions of the offshore photovoltaic module. While ensuring the connection stability between the ladder structure and the upper support structure, the flexibility of the ladder structure is improved.

[0038] In this disclosure, offshore photovoltaic systems may include an upper support structure for supporting photovoltaic panels. In the actual structure, the specific positional relationship between the upper support structure and the sea level can be selected according to the specific angle requirements of the photovoltaic panels. For example, to improve the efficiency of the photovoltaic panels, the angle between the photovoltaic panels and the sea level can be 15°, and consequently, the angle between the upper support structure and the sea level can also be 15°. In this disclosure, the angle between the upper support structure and the sea level can refer to the angle between the upper surface, lower surface, or a certain cross-section of the upper support structure and the sea level. The specific plane selected can be chosen according to actual design or application requirements, and this disclosure does not impose specific limitations.

[0039] The upper support structure is composed of multiple members, such as a grid structure formed by connecting multiple upper chords, lower chords, and web members. The upper chords refer to multiple rod-like structures that contact the photovoltaic panels and provide direct support. The lower chords refer to multiple rod-like structures that connect to offshore pile foundations, located away from the photovoltaic panels and close to sea level. The offshore pile foundations are fixed at one end in the sea and extend above sea level at the other. The offshore pile foundations are fixed and connected to the upper support structure to form an overall support and fixing system for the photovoltaic panels. The ladder structure provided in this disclosure is mainly detachably connected to the members within the upper support structure, especially to the lower chords. The lower chords provide support for the ladder structure, allowing personnel to perform installation and maintenance operations on the offshore photovoltaic system via the ladder structure.

[0040] The following will be combined with the appendix Figure 1 To be continued Figure 5 The various parts of the ladder structure for offshore photovoltaic construction operations provided in this disclosure embodiment will be described in detail below:

[0041] In the embodiments provided in this disclosure, such as Figure 1 As shown, the ladder structure includes a first support component 10, which includes a main body 11 and a plurality of connecting rods 103.

[0042] The main body 11 includes a first support rod 101 and a second support rod 102 disposed opposite to each other. The extending directions of the first support rod 101 and the second support rod 102 may be the same or intersecting. In some embodiments, the extending directions of the first support rod 101 and the second support rod 102 intersect, and there is no intersection point between the first support rod 101 and the second support rod 102. In some embodiments, the first support rod 101 and the second support rod 102 are arranged parallel to each other. The positional relationship between the first support rod 101 and the second support rod 102 can be selected and adaptively adjusted according to the specific positional relationship of the rods in the upper support structure to which the ladder structure is connected.

[0043] The main body 11 also includes multiple connecting rods 103, which increase the mechanical strength of the main body 11 and provide more stable support for the structure. The multiple connecting rods 103 are connected between the first support rod 101 and the second support rod 102, for example, by welding. The connecting rods 103 can be parallel to each other or their extension directions can intersect, ensuring that each connecting rod 103 provides support.

[0044] In some embodiments, such as Figure 5 As shown, combined with Figure 1Multiple connecting rods 103 can be arranged in parallel to each other, and the gap between two adjacent connecting rods 103 is the same. The length of multiple connecting rods 103 is the same, which ensures that each connecting rod 103 can provide an effective connection for the first support rod 101 and the second support rod 102, and ensures the uniformity of force on multiple connecting rods 103.

[0045] In some embodiments, such as Figure 4 As shown, the extension directions of the multiple connecting rods 103 can be arranged in an intersecting manner. For example, two adjacent connecting rods 103 can form a triangular structure with the first support rod 101 or the second support rod 102, or two adjacent connecting rods 103 can form a trapezoidal structure with the first support rod 101 or the second support rod 102.

[0046] In some embodiments, the multiple connecting rods 103 can be telescopic structures, and one or more of the multiple connecting rods 103 can be telescopic rods. The specific length of the connecting rod 103 can be determined according to the connection position between the climbing structure and the upper support structure, so that the climbing ladder can be adapted to multiple positions within the upper support structure, thereby improving the flexibility of the climbing structure.

[0047] In this disclosure, the positional relationship between the first support rod 101, the second support rod 102, and the plurality of connecting rods 103 within the first support assembly 10 can be one or more combinations of the above embodiments, and the above embodiments do not constitute a specific limitation on this disclosure.

[0048] like Figure 4 and Figure 5 As shown, combined with Figure 1 The first support assembly 10 has limiting members 12 at both ends of its main body 11. The first support assembly 10 is detachably connected to the rods within the upper support structure via the limiting members 12. In this disclosure, the connection between the first support assembly 10 and the upper support structure mainly refers to the connection between the main body 11 and the lower chord rod in the upper support structure. The limiting member 12 can be a limiting steel pipe. After determining the overlap position between the ladder structure and the upper support structure, the two can be welded together using the limiting steel pipe. After the ladder structure is used, the limiting steel pipe can be disassembled. The limiting member 12 can also be a limiting block, a limiting ring, or other structures with limiting functions. The connection method between the limiting member 12 and the main body 11 and the upper support structure can be adaptively adjusted according to the specific type of the limiting member 12. Multiple connecting rods 103 need to be located between the limiting members 12 at both ends of the main body 11 to ensure the supporting function of the multiple connecting rods 103.

[0049] In the embodiments provided in this disclosure, such as Figure 3 As shown, combined with Figure 1The ladder structure includes a step assembly 30, which is connected to a first support assembly 10. The step assembly 30 can be a flat plate structure; for example, its shape can be rectangular or square. For ease of movement on the step assembly 30, it is typically a rectangular flat plate structure. The step assembly 30 includes a first surface 31 and a second surface 32. The first surface 31 is the side of the step assembly 30 facing away from the first support assembly 10, and the second surface 32 is the side of the step assembly 30 facing the first support assembly 10. The first surface 31 provides support, allowing personnel to step on it and thus providing support.

[0050] The pedal assembly 30 can be a flat plate structure with uniform thickness, i.e., the first surface 31 and the second surface 32 are parallel to each other; the pedal assembly 30 can also be a flat plate structure with gradually varying thickness, i.e., the first surface 31 and the second surface 32 are not parallel. Furthermore, in order to facilitate manufacturing and ensure the uniformity of the supporting force of the pedal assembly 30, the pedal assembly 30 can be a flat plate structure with uniform thickness.

[0051] In the embodiments provided in this disclosure, such as Figure 1 As shown, the ladder structure includes a second support assembly 20, which connects the first support assembly 10 and the step assembly 30. The second support assembly 20 includes four connectors and a reinforcing assembly 40. The four connectors are a first connector 201, a second connector 202, a third connector 203, and a fourth connector 204. Each connector is perpendicular to the first support rod 101, and all four connectors extend in the same direction, meaning they are parallel to each other.

[0052] The first connector 201 and the second connector 202 are spaced apart and connected to the first support rod 101, while the third connector 203 and the fourth connector 204 are spaced apart and connected to the second support rod 102. The spacing between the first connector 201 and the second connector 202 and the spacing between the third connector 203 and the fourth connector 204 may be the same or different. To ensure the stability of the connectors' support for the pedal assembly 30, the two spacing dimensions can usually be the same.

[0053] One end of the first connector 201, the second connector 202, the third connector 203, and the fourth connector 204 are respectively connected to the first support assembly 10, and the other end is respectively connected to the pedal assembly 30. The connectors are flush with the first support assembly 10, meaning the end of the connector is connected to the body of the first support rod 101 and the second support rod 102. The other end of each of the four connectors is connected to the pedal assembly 30. In some embodiments, the ends of the first connector 201, the second connector 202, the third connector 203, and the fourth connector 204 are all higher than the first surface 31 of the pedal assembly 30. This higher portion of the connector prevents the pedal assembly 30 from shifting during use, ensuring the stability of the ladder structure. In other embodiments, the ends of the first connector 201, the second connector 202, the third connector 203, and the fourth connector 204 are flush with the first surface 31 of the pedal assembly 30, which saves raw materials and reduces costs.

[0054] In the embodiments provided in this disclosure, the ladder structure includes a reinforcing component 40, which includes two first reinforcing rods 41 and two second reinforcing rods 42.

[0055] like Figure 1 and Figure 2 As shown, two first reinforcing rods 41 are respectively arranged in a direction parallel to the first support rod 101. One first reinforcing rod 41 is connected between the first connector 201 and the second connector 202, and the other first reinforcing rod 41 is connected between the third connector 203 and the fourth connector 204. The two sides of the pedal assembly 30 have the same extension direction as the two first reinforcing rods 41, and the two sides of the pedal assembly 30 are respectively connected to the two first reinforcing rods 41. The two first reinforcing rods 41 can provide support force for the pedal assembly 30 and improve the stability of the pedal assembly 30.

[0056] The connection between the pedal assembly 30 and the first reinforcing rod 41 can be one or more of the following methods: overlapping, welding, riveting, screwing, or bonding. To further improve the connection stability, the pedal assembly 30 and the first reinforcing rod 41 are usually connected by welding.

[0057] The length of the first reinforcing rod 41, located between the first connecting member 201 and the second connecting member 202, is equal to the distance between the first connecting member 201 and the second connecting member 202. The connection point between the first connecting member 201 and the first reinforcing rod 41 is the first intersection point 51, and the connection point between the second connecting member 202 and the first reinforcing rod 41 is the second intersection point 52. A first reinforcing part 401 is also provided between the first connecting member 201 and the second connecting member 202. The first reinforcing part 401 includes a first cross rod, the two ends of which are respectively connected to the first intersection point 51 and the second intersection point 52, and the other two ends of which are respectively connected to the ends of the first connecting member 201 and the second connecting member 202 near the first support assembly 10.

[0058] The first crossbar can be two rod-shaped or tubular components that are welded together, or it can be a one-piece cross structure. By setting the first crossbar between the first connector 201 and the second connector 202, the supporting effect of the first connector 201 and the second connector 202 can be strengthened, and deformation or damage to the first connector 201 and the second connector 202 due to external forces can be avoided.

[0059] The length of the first reinforcing rod 41, located between the third connector 203 and the fourth connector 204, is equal to the distance between the third connector 203 and the fourth connector 204. For example... Figure 2 As shown, combined with Figure 1 The connection point between the third connector 203 and the first reinforcing rod 41 is the third intersection point 53, and the connection point between the fourth connector 204 and the first reinforcing rod 41 is the fourth intersection point 54. A second reinforcing part 402 is also provided between the third connector 203 and the fourth connector 204. The second reinforcing part 402 includes a second cross rod. The two ends of the second cross rod are respectively connected to the third intersection point 53 and the fourth intersection point 54. The other two ends of the second cross rod are respectively connected to the end of the third connector 203 and the fourth connector 204 near the second support assembly 20.

[0060] The second crossbar can be two rod-shaped or tubular components that are welded together, or it can be a one-piece cross structure. By setting the second crossbar between the third connector 203 and the fourth connector 204, the supporting effect of the third connector 203 and the fourth connector 204 can be strengthened, and deformation or damage to the third connector 203 and the fourth connector 204 due to external forces can be avoided.

[0061] The first reinforcing part 401 and the second reinforcing part 402 can be simultaneously provided in the ladder structure, or only one of the first reinforcing part 401 or the second reinforcing part 402 can be provided in the ladder structure. The shapes of the first reinforcing part 401 and the second reinforcing part 402 can be the same or different. In order to further simplify the manufacturing process and improve the structural stability, the first reinforcing part 401 and the second reinforcing part 402 are usually the same in shape and structure and are symmetrically arranged.

[0062] like Figure 1 As shown, combined with Figure 3 Two second reinforcing rods 42 are arranged parallel to each other along a direction perpendicular to the first support rod 101. One second reinforcing rod 42 is connected between the first connector 201 and the fourth connector 204, and the other reinforcing rod is connected between the second connector 202 and the third connector 203. By setting the second reinforcing rods 42 in the second support assembly 20, the support stability of the four connecting rods can be improved.

[0063] The first reinforcing rod 41 and the second reinforcing rod 42 are not coplanar, which can improve the support strength of the first and second connecting rods for the pedal assembly 30, and at the same time improve the connection stability of the four connecting rods in the second support assembly 20. For example, the second reinforcing rod 42 can be located at one end of the connecting rod near the first support assembly 10. For example, the second reinforcing rod 42 can be located in the middle of the connecting rod.

[0064] The second reinforcing rod 42 and the connecting rod can be connected by one or more of the following methods: welding, riveting, screwing, or bonding. In order to further improve the connection stability, the second reinforcing rod 42 and the connecting rod are usually connected by welding.

[0065] The length of the second reinforcing rod 42, located between the first connecting member 201 and the fourth connecting member 204, is less than the distance between the pedal assembly 30 and the first support assembly 10. For example... Figure 3 As shown, a third reinforcing part 403 is provided between the first connecting member 201 and the fourth connecting member 204. The third reinforcing part 403 is provided in a direction parallel to the first connecting member 201. One end of the third reinforcing part 403 is connected to the second reinforcing rod 42, and the other end of the third reinforcing part 403 is connected to the second surface 32 of the pedal assembly 30.

[0066] The third reinforcing part 403 can be a rod-shaped structure. The third reinforcing part 403 can include one rod-shaped structure or multiple rod-shaped structures arranged side by side. The third reinforcing part 403 is used to support the pedal assembly 30 and prevent the pedal assembly 30 from deforming due to external forces. In addition, the third reinforcing part 403 can also distribute the force on the first connecting rod and the fourth connecting rod to prevent the connecting rod from deforming or being damaged due to uneven force distribution.

[0067] The length of the second reinforcing rod 42, located between the second connector 202 and the third connector 203, is less than the distance between the pedal assembly 30 and the first support assembly 10. A fourth reinforcing part 404 is provided between the second connector 202 and the third connector 203. The fourth reinforcing part 404 is arranged in a direction parallel to the first connector 201. One end of the fourth reinforcing part 404 is connected to the second reinforcing rod 42, and the other end of the fourth reinforcing part 404 is connected to the second surface 32 of the pedal assembly 30.

[0068] The fourth reinforcing part 404 can be a rod-shaped structure. The fourth reinforcing part 404 can include one rod-shaped structure or multiple rod-shaped structures arranged side by side. The fourth reinforcing part 404 is used to support the pedal assembly 30 and prevent the pedal assembly 30 from deforming due to external forces. In addition, the fourth reinforcing part 404 can also distribute the force on the second connecting rod and the third connecting rod to prevent the connecting rod from deforming or being damaged due to uneven force distribution.
