Description

Technical Field

[0001] The present invention relates to the technical field of mooring tensioners, and particularly to a floating wind power mooring tensioner with an automatic locking structure. Background Art

[0002] Mooring chains are important equipment for mooring and positioning of offshore floating systems. Among them, steel chains have become an essential component in mooring systems due to their excellent load-bearing capacity, fatigue resistance, and wear resistance. Traditional mooring systems use windlasses and chain stoppers for pre-tensioning, but they are costly and complex to operate, and are not suitable for mooring systems of offshore floating wind turbines. For floating production platforms or floating wind turbines, there is also a method of achieving pre-tensioning through the cooperation of a crane and a chain stopper, but this method has high requirements for the installation vessel, high cost, great difficulty, and is not conducive to large-scale installation operations. In addition, the chain will deflect at a certain angle during use, bringing non-axial forces to the joints between the chain and the platform (usually connecting shackles), affecting its service life. In the prior art, a universal joint only has a connecting function and requires a chain stopper to achieve length adjustment, occupying a large area of the floating body and being complex to install. Summary of the Invention

[0003] The purpose of the present invention is to solve the above technical problems and provide a floating wind power mooring tensioner with an automatic locking structure.

[0004] In order to achieve the above technical purpose and meet the above technical requirements, the technical solution adopted by the present invention is: a floating wind power mooring tensioner with an automatic locking structure, including a chain guiding module. A chain stopping module is arranged at the upper end of the chain guiding module. The chain passes through the middle parts of the chain guiding module and the chain stopping module. Pin shafts A are symmetrically arranged on both sides of the chain guiding module. The chain guiding module is connected to an internal rotating bracket through the pin shafts A and bushings A. The internal rotating bracket is fixed to an outer frame through bolts. Pin shafts B are symmetrically arranged on both sides of the outer frame. The outer frame is connected to an external rotating bracket through the pin shafts B and bushings B. The external rotating bracket is connected to a floating body, realizing the functions of rotation and automatic locking of the tensioner in two directions.

[0005] Preferably: The chain guiding module includes a chain guiding cylinder. Arc-shaped sliding rails are symmetrically arranged on both sides at the upper end of the chain guiding cylinder. Slideways extend outward on both sides of the upper surface of the sliding rails. A chain guiding channel is arranged inside the chain guiding cylinder.

[0006] Preferably: The upper part of the chain guiding cylinder is of a square structure, with a cross-shaped chain guiding hole in the center. The middle part of the chain guiding cylinder is of a cylindrical structure, and the internal cross-shaped chain guiding channel is formed by four L-shaped brackets arranged in an array. The lower part of the chain guiding cylinder is of a flat drum-shaped structure, with a horn-shaped chain guiding opening arranged inside.

[0007] Preferably, the chain stop module includes symmetrically arranged chain stop blocks. A chute is provided on the side of the chain stop block away from the chain. Roller assemblies are symmetrically arranged in the chute, and the roller assemblies cooperate with the slideway for sliding. When the chain passes through from bottom to top, the chain stop block moves out of the way through the slide rail. When the chain passes through in the reverse direction from top to bottom, the chain stop block automatically locks downward due to gravity.

[0008] Preferably, an arc groove corresponding to the outer circle of the chain link is provided in the middle of the opposite surfaces of the two chain stop blocks, and arc-shaped portions corresponding to the inner circle of the chain link are symmetrically provided on the outer side surfaces of the chain stop blocks.

[0009] Preferably, the roller assembly includes roller groups symmetrically arranged in the chute. Symmetric roller grooves are provided on the opposite side surfaces of the chute. Rollers are arranged in the roller grooves, and the rollers are connected to the chain stop blocks by bolts.

[0010] Preferably, a plurality of lifting lugs are symmetrically arranged at the upper end of the chain stop block. When it is necessary to loosen the chain, the chain stop block is pulled to the top by connecting the lifting lugs with a crane.

[0011] Compared with the traditional structure, the beneficial effects of the present invention are as follows: The structure is compact, the installation is convenient, the occupied area of the floating body is small, the tensioner has the functions of rotating in two directions and automatically locking the chain, the adjustment of the chain length and the automatic locking can be realized without using a chain stopper in combination, effectively improving the installation efficiency, reducing the installation cost, reducing the risk of chain breakage, increasing its service life, being safe and reliable in use, and having high practical value.

[0023] In this preferred embodiment, the upper part of the chain guiding cylinder 62 is of a square structure, and a cross-shaped chain guiding hole is arranged in the center. The middle part of the chain guiding cylinder 62 is of a cylindrical structure, and the inner part is composed of four L-shaped brackets arranged in an array to form a cross-shaped chain guiding channel. The lower part of the chain guiding cylinder 62 is of a flat drum-shaped structure, and a horn-shaped chain guiding port is arranged inside.

[0024] In this preferred embodiment, the chain stop module 2 includes symmetrically arranged chain stop blocks 21. A slide groove 213 is arranged on the side of the chain stop block 21 away from the chain. Roller assemblies 23 are symmetrically arranged in the slide groove 213, and the roller assemblies 23 cooperate with the slideways 611 to slide. When the chain 1 passes through from bottom to top, the chain stop block 21 moves out of the way through the slide rail. When the chain passes through from top to bottom in the reverse direction, the chain stop block 21 automatically locks downwards due to gravity.

[0025] In this preferred embodiment, arc grooves 211 corresponding to the outer circle of the chain link are arranged in the middle of the opposite surfaces of the two chain stop blocks 21, and arc parts 212 corresponding to the inner circle of the chain link are symmetrically arranged on the outer side surfaces of the chain stop blocks 21.
