Description

Technical Field

[0001] The utility model relates to the technical field of marine engineering equipment, in particular to a wave compensation supporting device for an offshore pier. Background Art

[0002] In recent years, with the continuous optimization and upgrading of the global energy structure, offshore wind power, as a green and sustainable new energy, is ushering in a golden period of rapid development. The growing offshore wind power market has not only put forward higher requirements for the innovation of wind power technology, but also put forward more stringent standards for the performance and design of wind power operation and maintenance mother vessels (SOV). Especially in deep and deep sea areas, the adaptability of wind power operation and maintenance vessels to sea conditions has become the focus of design.

[0003] At present, wind power operation and maintenance vessels in the market mainly rely on the tower base boarding method to transport personnel. However, with the continuous expansion of wind farm scale and the increasing complexity of operation and maintenance needs, this traditional boarding method has become increasingly difficult to meet the needs of owners. The method of boarding offshore piers on operation and maintenance vessels has emerged as the times require. It can not only improve the safety of personnel transportation, but also greatly improve the operation and maintenance efficiency. Therefore, it is being adopted by more and more wind power operation and maintenance vessels.

[0004] Due to the complexity and variability of the marine environment, especially the influence of wind and waves, the connection position between the offshore trestle and the wind power platform is prone to deviation. This deviation not only affects the normal transportation of personnel, but also may bring safety hazards. Therefore, how to ensure the stable connection between the offshore trestle and the wind power platform has become an important issue in the design of wind power operation and maintenance ships.

[0005] In order to solve this problem, the design of a corresponding jacking mechanism for the offshore trestle has become the key. This jacking mechanism needs to be able to automatically compensate for the position deviation between the offshore trestle and the wind power platform under the influence of wind and waves to ensure the stable connection between the two. This not only requires the mechanism to have a high degree of flexibility and adaptability, but also requires it to be able to maintain stable performance in extreme marine environments. Therefore, it is of great significance to design a jacking mechanism that effectively improves the stability of the connection between the offshore trestle and the wind power platform and ensures the safe and efficient operation of wind power operation and maintenance ships.

[0010] In a preferred solution, the material of the elastic shock absorbing block 1 and the elastic shock absorbing block 2 is any one of polyurethane and rubber.

[0011] In a preferred solution, the connecting rod mechanism includes a first connecting rod, a second connecting rod, a third connecting rod, and a fourth connecting rod which are hinged to each other, and the first connecting rod and the second connecting rod are hinged to a connecting rod support.

[0012] In a preferred solution, the first connecting rod, the second connecting rod, the third connecting rod and the fourth connecting rod are frame structures.

[0013] In a preferred solution, the buffer block is installed on the third connecting rod and / or the fourth connecting rod.

[0014] In a preferred solution, the telescopic rod includes a first telescopic rod and a second telescopic rod, and the first telescopic rod and the second telescopic rod are respectively connected to the fourth connecting rod and the third connecting rod through joint bearings.

[0015] In a preferred solution, the third connecting rod and the fourth connecting rod have an arch structure.

[0016] The beneficial effects achieved by the utility model are:

[0017] First, the utility model designs a connecting rod mechanism, and the connecting part between the connecting rod mechanism and the offshore wind power platform is designed to be an arched connecting rod equipped with a buffer block, and the arched connecting rod is connected by a telescopic rod and a joint bearing. When the connecting rod mechanism is impacted, the buffer block absorbs part of the impact, and the connecting rod mechanism can buffer the impact by passively changing its shape, and the shape change mode includes telescoping and swinging left and right; through the above method, the impact caused by changes in the marine environment can be effectively buffered, compensated and adapted, and the stability of the connection between the offshore pier and the wind power platform is improved;

The two elastic shock-absorbing blocks are made of polyurethane or rubber materials. The two elastic shock-absorbing blocks are connected to the connecting rod support and the base through pins. When the connecting rod mechanism is impacted, even if the impact comes from different directions, the connecting rod mechanism can absorb the impact energy through various methods such as pitching, flipping, and twisting by relying on the deformation of the elastic shock-absorbing blocks. The deformation of the elastic shock-absorbing blocks can be in the form of compression, shearing, bending or stretching, depending on the design of the shock-absorbing blocks and the direction of the force they are subjected to. The elastic shock-absorbing blocks can quickly return to their original shape after being impacted, which helps maintain the stability of the structure and reduce residual vibration after the impact;

[0019] Third, two elastic shock-absorbing blocks connected in series by pins are designed, which helps the two elastic shock-absorbing blocks to produce mutual friction during the deformation process. This friction consumes part of the impact energy and achieves a better shock-absorbing effect. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the forms of the various structures recorded in the following embodiments are merely illustrative, and the utility model is not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0030] Reference Figure 1-Figure 7 The utility model is a wave compensation supporting device for an offshore pier, which includes a base 34, a telescopic rod 32, a connecting rod support 33 and a connecting rod mechanism 36 connected to the connecting rod support 33, the connecting rod mechanism 36 includes a first connecting rod 361, a second connecting rod 362, a third connecting rod 363, and a fourth connecting rod 364 that are hinged to each other, and the first connecting rod 361 and the second connecting rod 362 are hinged to the connecting rod support 33. The first connecting rod 361, the second connecting rod 362, the third connecting rod 363, and the fourth connecting rod 364 are frame structures, which help to increase stability. The third connecting rod 363 and the fourth connecting rod 364 are connecting rods connected to the offshore wind power platform, which are preferably designed as an arch structure, such as a polygonal structure or an arc structure, and the buffer block 35 is installed on the third connecting rod 363 and / or the fourth connecting rod 364. The buffer block 35 is preferably made of rubber material. The telescopic rod 32 includes a first telescopic rod 321 and a second telescopic rod 322, which are respectively connected to the fourth connecting rod 364 and the third connecting rod 363 through joint bearings 37. The joint bearings 37 enable the connecting rod mechanism 36 to change its shape with multiple degrees of freedom.

[0031] When the connecting rod mechanism 36 is impacted, part of the impact is absorbed by the buffer block 35. At the same time, the connecting rod mechanism 36 can buffer the impact by passively changing its shape, and the shape change methods include extension and contraction and left and right swinging. Through the above method, the impact caused by changes in the marine environment can be effectively buffered, compensated and adapted, thereby improving the stability of the connection between the offshore pier and the wind power platform.

[0032] An impact compensation mechanism 31 is installed between the connecting rod support 33 and the base 34 to realize the elastic connection between the connecting rod support 33 and the base 34. The impact compensation mechanism 31 includes an elastic shock absorbing block 1 311 and an elastic shock absorbing block 2 312. The elastic shock absorbing block 1 311 and the elastic shock absorbing block 2 312 are provided with pin holes. The connecting rod support 33, the elastic shock absorbing block 1 311 and the elastic shock absorbing block 2 312 are connected in series by pins; the elastic shock absorbing block 2 312 is installed in the base 34. The preferred installation method is that a clamping seat 313 is provided between the elastic shock absorbing block 2 312 and the base 34, the elastic shock absorbing block 2 312 is clamped in the clamping seat 313, and the clamping seat 313 is fixed to the base 34 by screws.

[0033] The middle parts of the connecting rod support 33, the elastic shock absorbing block 1 311 and the elastic shock absorbing block 2 312 are all provided with four pin holes distributed in a diamond structure. The elastic shock absorbing block 1 311 and the elastic shock absorbing block 2 312 are connected in series by four pins. This design helps the elastic shock absorbing block 1 311 and the elastic shock absorbing block 2 312 to generate mutual friction during the deformation process. This friction consumes part of the impact energy and achieves a better shock absorption effect.

[0034] The material of the elastic shock-absorbing block 1 311 and the elastic shock-absorbing block 2 312 can be selected from any one of polyurethane and rubber. The elastic shock-absorbing blocks made of polyurethane or rubber are prone to various forms of deformation such as compression, shearing, bending or stretching, and the elastic shock-absorbing blocks can quickly return to their original shape after being impacted, which helps to maintain the stability of the structure and reduce residual vibration after impact.

[0035] Embodiment 1,

[0036] In this embodiment, the base 34 of the wave compensation supporting device for the offshore trestle of the utility model is installed on the offshore trestle, and the offshore trestle is carried by the wind power operation and maintenance mother ship. The offshore trestle is against the wind power platform, so that the buffer block 35 is connected with the wind power platform. Figure 6 , Figure 7 shown.

[0037] When the offshore pier is impacted by environmental factors such as wind and waves, the buffer block 35 installed on the connecting rod mechanism 36 absorbs part of the impact energy, and the connecting rod mechanism 36 passively changes its shape to buffer the impact by telescoping and swinging left and right.

[0038] For impacts from different directions, the linkage mechanism 36 can absorb the impact energy by various ways such as pitching, flipping, twisting, etc., relying on the deformation of the elastic damping block. The deformation of the elastic damping block can be in the form of compression, shearing, bending or stretching, etc., depending on the design of the damping block and the direction of the force it bears. The elastic damping block can quickly return to its original shape after being impacted to maintain the stability of the structure and reduce the residual vibration after the impact.

[0039] The impact caused by changes in the marine environment is buffered, compensated and adapted through the above-mentioned method, thereby improving the stability of the connection between the offshore pier and the wind power platform.
