Description

Technical Field

[0001] This invention relates to the field of offshore wind power maintenance equipment technology, and in particular to a large-gap adaptive protection structure for offshore boarding bridges. Background Technology

[0002] In recent years, my country's installed wind power capacity has steadily increased, with offshore wind power accounting for a large proportion. By the end of 2021, my country had more than 5,000 offshore wind turbines installed. To ensure the normal operation of these turbines, regular inspections and daily maintenance are necessary. Currently, my country mostly uses small maintenance vessels to carry maintenance personnel. The vessels are moored at the turbine towers, and the personnel climb from the vessels to the wind turbine platforms. This working mode is highly dependent on the weather. In case of strong winds and waves, the vessels cannot moor, making inspection and maintenance impossible, and in severe cases, causing the turbines to shut down. In addition, wind and waves cause the vessel to roll, pitch, and sway, directly threatening the lives of personnel climbing from the vessel to the turbine towers. Existing technologies disclose some walkway devices that provide motion compensation. The walkway's telescopic ladder moves in pitch around its base or turntable, thereby compensating for the vessel's pitch and sway. A certain gap is left between the walkway ladder and the base or turntable to achieve the pitch movement. During pitching, this gap changes dynamically. If the gap becomes too large, it can easily cause physical injury to maintenance personnel. When personnel move around, it can easily cause physical injury, such as being squeezed or falling. Summary of the Invention

[0003] To address the aforementioned issues, this invention provides a large-gap adaptive protective structure for sea boarding bridges, effectively improving walking comfort and reducing the risk of people being squeezed or falling.

[0027] Furthermore,

[0028] The arc-shaped connecting surface includes an arc segment and a planar segment. One side of the planar segment is perpendicularly connected to the second vertical mounting surface, and the arc segment is connected to the other side of the planar segment.

[0040] This application provides a large-gap adaptive protective structure for sea boarding bridges to effectively improve walking comfort and reduce the risk of people being squeezed or falling.

[0041] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0042] First, it should be clarified that the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0043] The main implementation principles, specific implementation methods, and corresponding beneficial effects of the technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0044] Please refer to the attached document. Figure 1This application provides a large-gap adaptive protection structure for a sea boarding bridge, comprising: a first fixing structure, a second fixing structure, and a connecting section. The first fixing structure, the second fixing structure, and the connecting section can be made of stainless steel or aluminum alloy and subjected to anti-corrosion treatment. The first fixing structure includes a horizontal mounting surface 4 and a first vertical mounting surface 3. The upper end of the first vertical mounting surface 3 is perpendicularly connected to the horizontal mounting surface 4, and the horizontal mounting surface 4 extends away from the second fixing structure. The second fixing structure includes an arc-shaped connecting surface and a second vertical mounting surface 6. The surface includes an arc-shaped segment 15 and a flat segment 5. One side of the flat segment 5 is perpendicularly connected to the second vertical mounting surface 6, and the arc-shaped segment 15 is connected to the other side of the flat segment 5. The upper end of the second vertical mounting surface 6 is perpendicularly connected to one end of the arc-shaped connecting surface. The arc-shaped connecting surface extends towards the first fixed structure and bends downward in an arc shape. The connecting segment includes a movable compensation surface 7. The first side of the movable compensation surface 7 is hinged to the upper end of the first vertical mounting surface 3, and the second side of the movable compensation surface 7 is slidably connected to the upper surface of the arc-shaped connecting surface. The second side is parallel to the first side. Preferably, the movable compensation surface 7 is a stainless steel or aluminum alloy rectangular plate. The rectangular plate is slidably connected to the upper surface of the arc-shaped connecting surface by rollers. The surface of the movable compensation surface 7, especially the lower surface, is provided with reinforcing ribs.

[0045] For details, please refer to Figure 2 The base 1 of the sea boarding bridge is movably connected to the end of the telescopic ladder 2. The telescopic ladder can rotate up and down around the base. The position of the movable connection between the base 1 and the telescopic ladder 2 is lower than the connecting section.

[0046] The above embodiments can be installed in the following manner: the horizontal mounting surface 4 is fixedly installed on the upper horizontal surface of the end of the base 1 of the boarding bridge; the first vertical mounting surface 3 is fixedly installed on the vertical surface of the end of the base 1 of the boarding bridge; and the second vertical mounting surface 6 is fixedly installed on the vertical surface of the end of the telescopic ladder 2 of the boarding bridge.

[0047] Alternatively, the installation method can be reversed: the horizontal mounting surface 4 is fixedly installed on the upper horizontal surface of the end of the telescopic ladder 2 of the boarding bridge; the first vertical mounting surface 3 is fixedly installed on the vertical surface of the end of the telescopic ladder 2 of the boarding bridge; and the second vertical mounting surface 6 is fixedly installed on the vertical surface of the end of the base 1 of the boarding bridge.

[0048] There is no essential difference between the two installation methods described above. However, relatively speaking, the first installation method is preferred because the base 1 of the boarding bridge has a larger installation area. In the above embodiment, the base 1 of the boarding bridge is connected to the end of the telescopic ladder 2 via a shaft.

[0049] To ensure that the movable compensation surface 7 is tightly fitted onto the upper surface of the arc-shaped connecting surface, the lower surface of the movable compensation surface 7 is connected to the first vertical mounting surface 3 via an elastic device 10, and the connection point between the elastic device 7 and the first vertical mounting surface 3 is lower than the hinge point between the movable compensation surface 7 and the first vertical mounting surface 3. Preferably, the elastic device 10 is a preload spring, but it can also be other similar structures, such as an elastic strip, a cylinder, etc. When the elastic device 10 is a preload spring, both ends of the preload spring are pinned to the lower surface of the movable compensation surface 7 and the first vertical mounting surface 3, respectively.

[0050] Specifically, when the boarding bridge is in a horizontal position, the second side of the movable compensation surface 7 is slidably connected to the upper surface of the planar segment 5 or the arc-shaped segment 15. As a preferred embodiment, refer to... Figure 3 The second side of the movable compensation surface 7 is slidably connected to the upper surface of the planar segment 5. Under the action of the pre-tension spring, the movable compensation surface 7 is tightly fastened to the upper surface of the arc-shaped connecting surface, thereby forming a continuous surface that allows pedestrians to pass safely.

[0051] refer to Figure 4 When the boarding bridge is in the supine position, the second side of the movable compensation surface 7 is slidably connected to the upper surface of the planar segment 5. Under the action of the pre-tension spring, the movable compensation surface 7 is tightly fastened to the upper surface of the arc-shaped connecting surface, thereby forming a continuous surface that allows pedestrians to pass safely.

[0052] refer to Figure 5 When the boarding bridge is in the downward position, the second side of the movable compensation surface 7 is slidably connected to the upper surface of the arc segment 15. Under the action of the pre-tension spring, the movable compensation surface 7 is tightly fastened to the upper surface of the arc connecting surface, thereby forming a continuous surface that allows pedestrians to pass safely.

[0053] The present invention discloses a large-gap adaptive protective structure for a boarding bridge at sea. By establishing a first fixed structure, a second fixed structure, and a connecting section, the movable compensation surface 7 can continuously cover the gap between the ladder and the base or turntable of the boarding bridge when pitching motion occurs, forming a continuous corridor. This can effectively improve walking comfort and reduce the risk of people being squeezed or falling.
