Description

Technical Field

[0001] This utility model relates to the field of offshore wind power technology, and in particular to an anti-collision device for offshore wind power platforms. Background Technology

[0002] As the core facility of offshore wind power systems, offshore wind power platforms are exposed to the complex marine environment for a long time and face multiple safety risks. Among them, ship collisions and floating object impacts (such as ice floes and marine debris) are among the main factors threatening their structural safety.

[0003] To ensure the safe operation of offshore wind power platforms, various anti-collision devices have been developed in existing technologies, such as rubber fenders, steel anti-collision rings, or buffer supports installed on the outside of the platform foundation columns. However, some current anti-collision devices adopt a fully encircling structure, which, while providing relatively comprehensive protection, obstructs the platform foundation columns (especially those with ladders). This forces personnel to bypass the anti-collision structure when using the ladders to access the platform, increasing operational difficulty and safety hazards, and affecting maintenance efficiency. Utility Model Content

[0004] This utility model aims to solve, at least to some extent, one of the problems existing in the existing related technologies. To this end, this utility model proposes an anti-collision device for offshore wind power platforms that can achieve comprehensive and efficient anti-collision protection while also taking into account the convenience of personnel passage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A collision avoidance device for an offshore wind power platform includes a base platform and multiple foundation columns surrounding the outer side of the base platform. One of the foundation columns is a main foundation column, and the rest are secondary foundation columns. A ladder connects the main foundation column to the base platform. A protective ring frame surrounds all the foundation columns. The protective ring frame includes a large arc frame and a small arc frame. Several buffer protective components are provided on the outer side of both the large and small arc frames. The large arc frame is fixed to the secondary foundation column and has a notch at the position of the main foundation column. The small arc frame is movably connected to the main foundation column and is located within the notch. A driving device is also provided on the main foundation column. The driving device is used to drive the small arc frame to move, causing the small arc frame to open or close the notch.

[0006] In some embodiments, the small arc frame includes a first arc frame and a second arc frame symmetrically arranged, and a first rotating sleeve and a second rotating sleeve that are rotatably sleeved on the main foundation column are respectively arranged on the side of the first arc frame and the second arc frame that are close to each other.

[0007] In some embodiments, the driving device includes an electric push rod disposed at the upper end of the main foundation column, a first vertical rod extending upward on one side of the first rotating sleeve, a second vertical rod extending upward on one side of the second rotating sleeve, a moving block disposed on the push rod of the electric push rod, a transverse sliding groove disposed on the moving block, and one end of the first vertical rod and the second vertical rod being movably disposed within the transverse sliding groove.

[0008] In some embodiments, the buffer protection component includes a transverse guide rod, one end of which is movably inserted into a large arc frame / small arc frame, and the other end is provided with a roller fixing frame. An anti-collision roller is provided on the roller fixing frame, and a buffer spring is also provided inside the roller fixing frame, the buffer spring being sleeved on the transverse guide rod.

[0009] In some embodiments, the anti-collision rollers are arranged vertically.

[0010] In some embodiments, the anti-collision roller includes a rotating rod, and a cylinder is provided on the outer sleeve of the rotating rod, the cylinder being made of rubber.

[0011] In some embodiments, a reinforcing diagonal brace connects the foundation platform to the foundation column.

[0012] In some embodiments, a fence is provided on the base platform.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The protective ring frame consists of a large arc frame and a small arc frame. Under normal conditions, the small arc frame closes the gap, so that the protective ring frame forms a complete ring structure that can surround the foundation column in all directions and intercept impacts from all directions.

[0014] 2. When personnel need to climb up or down the platform via the ladder of the main foundation column, the drive device moves the small arc frame to open the gap, directly exposing the ladder position. There is no need to bypass the anti-collision structure, which significantly improves passage efficiency and safety, and is especially suitable for emergency maintenance or emergency evacuation scenarios.

[0020] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0021] like Figures 1-5 The diagram shows an anti-collision device for an offshore wind power platform, comprising a base platform 1 and multiple base columns 2 surrounding the base platform 1 around its circumference. One of the multiple base columns 2 is a main base column, and the rest are secondary base columns. A ladder 9 connects the main base column to the base platform 1. A protective ring frame 3 surrounds all the base columns 2. The protective ring frame 3 includes a large arc frame 4 and a small arc frame 5. Several buffer protective components are provided on the outer side of both the large arc frame 4 and the small arc frame 5. The large arc frame 4 is fixed to the secondary base column and has a notch 6 at the position of the main base column. The small arc frame 5 is movably connected to the main base column and is located within the notch 6. A driving device is also provided on the main base column. The driving device is used to drive the small arc frame 5 to move, causing the small arc frame 5 to open or close the notch 6.

[0022] Furthermore, the foundation platform 1 is made of welded steel structure and has a circular or polygonal structure. Multiple foundation columns 2 are evenly distributed along the circumference on one side of its bottom. The foundation columns 2 are made of high-strength steel pipes and are fixed to the seabed at the bottom. One of them is the main foundation column for installing the ladder 9. The ladder 9 has an anti-slip tread design and is equipped with guardrails on both sides.

[0023] The protective ring frame 3 is made of alloy steel. The large arc frame 4 is fixed to the outside of the secondary foundation column by a flange. A notch 6 is formed on one side of the large arc frame 4 at the position of the main foundation column. The small arc frame 5 is an arc structure that matches the notch 6 and can be driven by a drive device to open or close the notch 6.

[0024] Thus, through the above structure, the protective ring frame 3 is composed of a large arc frame 4 and a small arc frame 5. Under normal conditions, the small arc frame 5 closes the gap, so that the protective ring frame 3 forms a complete ring structure, which can surround the base column in all directions and intercept impacts from all directions.

[0025] When personnel need to go up or down the platform via the ladder 9 of the main foundation column, the small arc frame 5 is moved by the drive device to open the gap 6, directly exposing the position of the ladder 9. There is no need to go around the anti-collision structure, which significantly improves the passage efficiency and safety, and is especially suitable for emergency maintenance or emergency evacuation scenarios.

[0026] In this utility model, the small arc frame 5 includes a first arc frame 21 and a second arc frame 22 symmetrically arranged. On the side of the first arc frame 21 and the second arc frame 22 that are close to each other, a first rotating sleeve 23 and a second rotating sleeve 24 are respectively arranged and rotated on the main foundation column.

[0027] The first arc frame 21 and the second arc frame 22 of the small arc frame 5 are symmetrical semi-arcs, and their curvature is the same as that of the large arc frame 4. The first rotating sleeve 23 and the second rotating sleeve 24 are circular sleeves with bronze bushings inlaid on their inner walls. They are welded to the inner middle of the first arc frame 21 and the second arc frame 22 respectively, and are symmetrically sleeved on the outside of the main foundation column. A gap of 5-10mm is reserved between the sleeve and the main foundation column to ensure smooth rotation.

[0028] See Figure 3 As shown, when the first arc-shaped frame 21 and the second arc-shaped frame 22 are opened, they can be simultaneously unfolded to both sides, increasing the passage width of the gap 6 and making it easier for personnel to carry tools up and down the ladder 9.

[0029] See Figures 3-5 As shown, the driving device includes an electric push rod 31 located at the upper end of the main foundation column, a first vertical rod 32 extending upward on one side of the first rotating sleeve 23, a second vertical rod 33 extending upward on one side of the second rotating sleeve 24, a moving block 34 on the push rod of the electric push rod 31, and a transverse sliding groove 35 on the moving block 34. One end of the first vertical rod 32 and the second vertical rod 33 are movably disposed within the transverse sliding groove 35.

[0030] When the electric push rod 31 drives the moving block 34 to move back and forth, the transverse sliding groove 35 of the moving block 34 causes the first vertical rod 32 and the second vertical rod 33 to swing to the sides or the middle, thereby causing the first rotating sleeve 23 and the second rotating sleeve 24 to rotate, thus realizing the opening and closing of the small arc frame 5.

[0031] See Figure 2 , Figure 5 As shown, the buffer protection component includes a transverse guide rod 41. One end of the transverse guide rod 41 is movably inserted into the large arc frame 4 / small arc frame 5, and the other end is provided with a roller fixing frame 42. An anti-collision roller 43 is provided on the roller fixing frame 42. A buffer spring 44 is also provided inside the roller fixing frame 42, and the buffer spring 44 is sleeved on the transverse guide rod 41.

[0032] The transverse guide rod 41 is a chrome-plated solid steel rod. One end is movably inserted into the reserved hole of the large arc frame 4 / small arc frame 5 through a bushing, and the other end is welded and fixed to the roller fixing frame 42. The roller fixing frame 42 is a U-shaped steel structure, and the anti-collision roller 43 is installed inside through bearings. The buffer spring 44 is a high-strength compression spring, which is sleeved on the part of the transverse guide rod 41 located between the roller fixing frame 42 and the arc frame. Under natural conditions, the spring is in a slightly compressed state to ensure that the anti-collision roller 43 and the arc frame maintain a preset distance. When impacted, the anti-collision roller 43 pushes the roller fixing frame 42 to compress the spring, and the transverse guide rod 41 slides along the bushing to achieve buffering and energy absorption.

[0033] Since the buffer spring 44 is used at sea, it must meet the three core requirements of corrosion resistance, high strength and high elasticity. Therefore, the buffer spring 44 is made of 316 stainless steel spring steel.

[0034] Furthermore, the anti-collision roller 43 is vertically arranged, and the anti-collision roller 43 includes a rotating rod, and a cylinder is provided on the outer sleeve of the rotating rod, the cylinder being made of rubber.

[0035] The rotating rod of the anti-collision roller 43 is made of high-strength alloy steel pipe, with a rubber cylinder of 100-200mm thickness on the outside. The rubber material is made of chloroprene rubber that is resistant to seawater corrosion, and steel wire mesh is added inside to enhance the structural strength.

[0036] In this invention, a reinforcing diagonal brace 71 is connected between the foundation platform 1 and the foundation column 2, which enhances the structural stability of the entire wind power platform.

[0037] The basic platform 1 is equipped with a fence 81, which provides a safety barrier for workers on the platform and effectively prevents them from accidentally falling into the sea. This is especially beneficial in environments with large waves, thus improving the operational safety of the platform.

The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
