Description

Technical Field

[0001] This invention relates to the field of marine engineering technology, and more particularly to a berthing isolation device for a floating wind power platform dock. Background Technology

[0002] In recent years, the offshore wind power industry has developed rapidly, and floating wind power platforms have emerged. When such platforms are integrated at the dock, they need to be berthed. Due to their special structure, there are the following difficulties and risks: (1) Traditional floating wind power platforms mostly adopt a column structure. In order to improve the platform's motion performance, each column usually has a heave chamber at the bottom. When the platform is berthed, a special structure needs to be set up to avoid collision between the heave cabin and the dock or other isolation structure; (2) If the isolation barge is used as the isolation structure between the floating wind power platform and the dock, there is a possibility of collision between the bottom of the isolation barge and the heave cabin of the wind power platform under the action of harsh environment; (3) If the berthing ball is used directly as the isolation buffer between the wind power platform and the dock, after evaluation based on the existing large-size berthing ball size, the heave cabin still has the risk of collision with the dock; (4) There are many forms of berthing at the dock. The vertical height available for setting the berthing ball in the front plane of the steel pile dock is too narrow, which cannot meet the requirements for contact and connection of the berthing ball; (5) As a buffer and energy absorption component between the wind power platform and the dock, the connection position of the berthing ball needs to be carefully considered. If the berthing ball is connected to the platform end, a large-size structure needs to be made on the dock side to ensure that the berthing ball can touch the dock facade under different environmental conditions, tides, and drafts. This scheme requires that the dock berthing surface has sufficient vertical space. The steel pile dock cannot meet the above requirements. Therefore, the form of connecting the berthing ball to the platform end has certain limitations. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a device for isolating the platform and the berthing dock during the berthing operation of a floating wind power platform.

[0004] To address the aforementioned technical problems, this invention provides a floating wind power platform dock berthing isolation device for use between a floating wind power platform and a dock. The device includes a dock support frame, counterweights, a buoy, and a hull collision frame. The dock support frame comprises a T-shaped horizontal plane and an external facade. The horizontal plane is laid flat and fixed to the dock, with multiple counterweights stacked on its top surface. A panel is covered on the side of the external facade facing away from the horizontal plane, and a buoy is connected to the panel. The hull collision frame is fixedly installed on a floating wind power platform column opposite to the buoy.

[0005] According to a preferred embodiment of the present invention, an extension structure is provided on the top of the exterior facade panel.

[0006] According to a preferred embodiment of the present invention, the gap between the counterweight and the internal structure of the dock support frame is filled with a plurality of wooden blocks.

[0007] According to a preferred embodiment of the present invention, the counterweight is made of cement or cast iron.

[0008] According to a preferred embodiment of the present invention, the wharf support frame is a plate beam steel structure.

[0009] According to a preferred embodiment of the present invention, the center of the ball is located slightly below the center of the exterior facade.

[0010] According to a preferred embodiment of the present invention, the surface of the ball is covered with a tire protective cover.

[0011] According to a preferred embodiment of the present invention, the ball is an inflatable rubber fender.

[0012] According to a preferred embodiment of the present invention, the horizontal length of the hull collision frame is less than the width of the column of the floating wind power platform.

[0013] According to a preferred embodiment of the present invention, the hull collision frame is a frame structure welded from steel pipes of various sizes.

[0014] The technical effects of this invention are as follows: 1. This invention discloses a berthing isolation device for a floating wind power platform. The berthing support frame is a T-shaped structure, placed at the front edge of the berthing berth, serving as a fixed connection point between the berthing ball and the berthing berth, and providing a supporting plane for the berthing ball. The counterweight block can be a heavy-duty facility such as a cement block or cast iron block, placed on the berthing support frame for counterweighting, while also providing anti-compression and anti-friction functions. The berthing ball is a large-sized inflatable rubber fender, covered with a chain rubber protective sleeve, and connected to the berth support frame via chains on both sides. It is used to absorb the collision energy of the floating wind power platform during movement, ensuring sufficient horizontal clearance between the platform and the berth. The hull collision frame is arranged on the floating wind power platform columns to increase the horizontal clearance between the platform columns and the berth, minimizing collisions between the heave chamber and the berth, thereby achieving the beneficial effect of isolating the platform and the berthing berth during floating wind power platform berthing operations.

[0015] 2. This invention provides a floating wind power platform dock berthing isolation device. It utilizes the hull support frame to increase the horizontal distance between the platform and the dock when berthing. It uses a large-sized berthing ball to ensure sufficient clearance between the hull and the dock under harsh environmental conditions. By setting up the dock support frame, the contact area of ​​the berthing ball is increased, which enhances the safety of dock berthing and expands the dock's business capabilities. The structure is simple, and it can be constructed using resources commonly found on the construction site. It is easy to build and install and can effectively reduce operating costs.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the invention.

[0019] like Figures 1 to 6 As shown, a floating wind power platform dock berthing isolation device is used for the floating wind power platform and the dock 1. It includes a dock support frame 3, counterweights 2, buoys 4, and a hull collision frame 5. The dock support frame 3 includes a horizontal surface 10 and an outer facade 8 arranged in a T-shape. The horizontal surface 10 is laid flat and fixed to the dock 1, and multiple counterweights 2 are stacked on the top surface of the horizontal surface 10. The surface of the outer facade 8 facing away from the horizontal surface 10 is covered with a panel, and the buoys 4 are connected to the panel. The hull collision frame 5 is fixedly installed on the floating wind power platform column 6 opposite to the buoys 4.

[0020] like Figures 1 to 6As shown, a floating wind power platform dock berthing isolation device is used to isolate and buffer between the floating wind power platform and the dock 1. The dock support frame 3 is a steel T-shaped plate beam structure, which is placed at the front edge of the dock 1. Multiple counterweights 2 are placed on the horizontal plane 10 of the dock support frame to increase the stability of the dock support frame 3. The ball 4 serves as a buffer energy absorption component and is connected to the outer facade 8 of the dock support frame by at least four chains. The hull collision frame 5 is set on the column 6 of the floating wind power platform to increase the horizontal distance between the floating wind power platform heave cabin 7 and the dock facade. When the wind blows from the sea surface toward the shore side of berthing dock 1, the floating wind turbine platform will move toward berthing dock 1. The berthing ball 4 in the dock berthing isolation device will be compressed and deformed, absorbing the collision energy of the ship. The size and installation position of the ship collision frame 5 will ensure that the floating wind turbine platform can always contact the berthing ball 4 during berthing. The dock support frame 3 serves as the fixed end connecting the berthing ball 4. On the one hand, it bears the compression and collision force of the berthing ball 4. On the other hand, its extension structure 9 is also used to prevent the berthing ball 4 from deviating from its position. The entire dock berthing isolation device, as a whole, ensures the safety of the floating wind turbine platform berthing operation.

[0021] like Figure 2 and Figure 5 As shown, the overall structure of the dock support frame 3 is T-shaped. It is made of common steel profiles (such as I-beams) welded into the main frame. The surface in contact with the ball 4 is covered with a panel to ensure a flat surface and facilitate the rolling of the ball 4 along the panel surface. An extension structure 9 is set on the top of the dock support frame 3 to prevent the ball from jumping out. The front end of the extension structure 9 is chamfered to avoid sharp structures piercing the ball 4. The dock support frame 3 is placed at the front edge of the berthing dock 1 and fits into the edge of the berthing dock 1. The structural dimensions of the horizontal plane 10 of the dock support frame must match the dimensions of the counterweight 2. The dimensions of the outer facade 8 of the dock support frame must be at least larger than the length and width projection dimensions of the maximum compression surface of the ball 4. A chain connection structure for the ball 4 is set on the surface to fix the ball 4.

[0022] like Figure 2 and Figure 3 As shown, counterweight 2 is a heavy counterweight facility, usually made of cement blocks or cast iron blocks. It is large in size and weight and is stacked inside the dock support frame 3 to increase the friction between the dock support frame 3 and the surface of the berthing dock 1. If there is a gap between the counterweight 2 and the inner wall of the dock support frame 3 after the counterweight 2 is in place, wooden blocks can be used to fill the gap to enhance the front pressure resistance of the dock support frame 3.

[0023] like Figure 3 and Figure 4As shown, the dock support frame 3 needs to be used in conjunction with a large-sized buoy 4 for dock mooring operations. The buoy 4 and the dock support frame 3 are connected at least 4 points using chains. The center of the buoy 4 should be set slightly below the center of the dock support frame 3 so that most of the pressure of the buoy 4 is applied to the facade of the dock 1, reducing the impact on the stress on the dock support frame 3. The large-sized buoy 4 is a conventional rubber product, a large-sized inflatable rubber fender, connected to the dock support frame 3 on both sides by chains, and covered with tire protective sleeves. Its size must match the collision frame 5 of the hull to ensure that there is still sufficient horizontal clearance between the floating wind power platform heave 7 and the dock when the buoy 4 is under maximum stress.

[0024] like Figure 2 and Figure 6 As shown, the hull collision frame 5 is a frame structure made of welded steel pipes. Its horizontal length and width dimensions need to match the dimensions of the floating wind power platform column 6, the floating wind power platform heave cabin 7, and the ball bearing 4. The horizontal length is slightly smaller than the width of the floating wind power platform column 6 to facilitate the structure's anchoring on the surface of the floating wind power platform column 6. In order to reduce the impact on the hydrodynamic performance of the floating wind power platform, the width of the hull collision frame 5 is designed to be smaller than the outer dimension of the floating wind power platform heave cabin 7. The overall height and installation position of the hull collision frame 5 cover the vertical range of the contact point between the ball bearing 4 and the hull collision frame 5 under different tides and environments. The principle for setting the upper and lower limits of vertical height is as follows: the lower limit should be lower than the lowest point of the collision between the hull and the ball bearing 4 when the hull sinks to its maximum amplitude under low tide and severe sea conditions; the upper limit should be higher than the highest point of the collision between the hull and the ball bearing 4 when the hull rises to its maximum amplitude under high tide and severe sea conditions. Under the premise of meeting structural strength requirements, the arrangement of members in the hull collision frame 7 should not be too dense to avoid affecting the hydrodynamic performance of the floating wind power platform. The structure of the hull collision frame 7 should avoid sharp parts to prevent puncturing the ball bearing 4 and affecting berthing safety.

[0025] The above-described embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention. The scope of protection of the present invention is defined by the claims.
