Description

Technical Field

[0001] The invention relates to the field of offshore wind power infrastructure, and in particular to a fender anti-collision structure for a wind turbine foundation. Background Art

[0002] Currently, there are various types of offshore wind power foundations. The main purpose is to stably support wind turbines. People can also climb onto the wind turbine foundation platform through the ladder inside the ship's components, and then perform maintenance and other operations on the wind turbine.

[0003] However, when a transport ship approaches the wind turbine foundation, due to environmental influences such as wind, waves and tides, the ship will experience violent up and down heave and unstable horizontal movement, which may cause friction and scratches between the ship and the mooring piles.

[0004] The friction generated by the above situation will damage the anti-corrosion coating of the attached components, thereby further shortening the service life of the wind power foundation. Summary of the invention

[0005] In order to increase the service life of a wind turbine foundation, the present application provides a fender anti-collision structure for a wind turbine foundation.

[0006] The present application provides a fender anti-collision structure for a wind turbine foundation, which adopts the following technical solution:

[0007] A fender anti-collision structure for a wind turbine foundation comprises an annular rubber fender for installation on the left and right sides of a berthing ladder of the wind turbine foundation, wherein the annular rubber fender is provided with a plurality of fender monomer sections along the length direction, and the plurality of fender monomer sections are detachably connected to each other; each of the fender monomer sections is detachably connected to a berthing pile through a clamp assembly.

[0008] By adopting the above technical solution, when the ship is berthing, the ship abuts against the outside of the annular rubber fender. When the ship shakes due to environmental influences such as wind, waves and tides, the buffering effect of the annular rubber fender can avoid direct contact between the ship and the berthing piles, thereby improving the service life of the wind turbine foundation; and when the annular rubber fender is damaged, it is only necessary to disassemble and replace the corresponding fender monomer, without replacing the entire annular rubber fender, thereby reducing costs.

[0009] Preferably, the clamp assembly comprises: a plurality of pairs of connecting plates spaced apart in the length direction of the fender unit and a plurality of clamp bodies adapted for mooring piles, fixing plates being fixedly mounted at both ends of the clamp body, the same pair of connecting plates being respectively fixedly mounted on both sides of the fender unit, the fixing plates at both ends of the clamp body being respectively abutted against the same pair of connecting plates, and the fixing plates and the connecting plates being fixedly connected by fasteners.

[0010] By adopting the above technical solution, when installing the annular rubber fender, the fender body is firstly sleeved on the outward side of the mooring pile, and then the hoop body is sleeved on the other side of the mooring pile and the fixing plate is abutted against the connecting plate, and then the two are connected by fasteners to complete the installation. The structure has high installation strength and is easy to install.

[0011] Preferably, the fastener comprises a fastening screw and a pair of fastening nuts, the fastening screw is passed through the connecting plate and the fixing plate at the same time, and the two fastening nuts are respectively threadedly installed on both ends of the fastening screw.

[0012] By adopting the above technical solution, the fastening screws are first synchronously inserted into the connecting plate and the fixing plate, and then fixed by the fastening nuts. The structure is simple and easy to operate.

[0013] Preferably, a limiting groove for the connecting plate to be inserted is formed on one side of the fixing plate close to the connecting plate.

[0014] By adopting the above technical solution, when the hoop body is sleeved on the mooring pile, the connecting plate is inserted into the limiting groove, thereby completing the alignment of the hole for the fastening screw to pass through, thereby improving the installation efficiency.

[0015] Preferably, a dovetail block is provided at one end of the fender monomer and a dovetail groove is provided at the other end, and the dovetail block of the fender monomer is plugged into the dovetail groove of the adjacent fender monomer.

[0016] By adopting the above technical solution, two adjacent fender units can be locked to each other by inserting the dovetail blocks into the dovetail grooves, which has a simple structure and is easy to install.

[0017] Preferably, a fixing screw is fixedly installed on the fender unit corresponding to the dovetail block, the fixing screw passes through the dovetail block, and a fixing nut is threadedly installed on the fixing screw.

[0018] By adopting the above technical solution, when the fender unit is damaged and removed for replacement, the dovetail block can be removed and used on the new fender unit, thereby further reducing the cost.

[0019] Preferably, the cross section of the annular rubber fender is semicircular.

[0020] By adopting the above technical solution, the annular rubber fender can be designed into a semicircular shape to achieve full contact with the ship, and the overall production cost can be reduced.

[0021] Preferably, the outer curved surface of the annular rubber fender is provided with wave patterns.

[0022] By adopting the above technical solution, the contact area between the annular rubber fender and the ship can be further increased.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When the ship is berthing, it abuts against the outside of the annular rubber fender. When the ship shakes due to environmental influences such as wind, waves and tides, the annular rubber fender can buffer the ship and avoid direct contact between the ship and the berthing piles, thereby increasing the service life of the wind turbine foundation. When the annular rubber fender is damaged, only the corresponding fender unit needs to be disassembled and replaced, without the need to replace the entire annular rubber fender, thus reducing costs.

[0025] 2. When installing the annular rubber fender, first put the fender body on the outward side of the mooring pile, then put the hoop body on the other side of the mooring pile and the fixing plate abuts against the connecting plate, and then connect the two with fasteners to complete the installation. This structure has high installation strength and is easy to install;

[0026] 3. Two adjacent fender units can be locked to each other by inserting the dovetail block into the dovetail groove, with simple structure and convenient installation. BRIEF DESCRIPTION OF THE DRAWINGS
