TECHNICAL FIELD

[0001] The present application relates to the field of offshore wind power equipment construction, in particular to a pile stabilizing platform for offshore wind power single pile construction. BACKGROUND

[0002] The offshore wind power construction industry is developing rapidly, and the erection of wind power foundation piles is a relatively important link in wind turbine installation, and precision control is particularly important. Among them, the wind power foundation pile is installed and constructed through the pile stabilizing platform to ensure its installation precision.

[0003] In related technologies, the pile stabilizing platform includes a mounting frame and two pile grippers, wherein the lower end of the mounting frame is provided with an anti-sinking plate seated on the seabed, and the two pile grippers are fixedly connected to one side of the upper end of the mounting frame and are spaced apart in the vertical direction to position and control the perpendicularity of the wind power foundation pile.

[0004] However, in actual application, since the two pile grippers are cantilever structures, the center of gravity of the pile stabilizing platform is easily offset during hoisting, causing the pile stabilizing platform to tilt and affecting the installation requirements of the wind power foundation pile, and therefore improvement is needed. CONTENT OF THE UTILITY MODEL

[0005] In order to avoid the center of gravity of the pile stabilizing platform from being offset as much as possible, the present application provides a pile stabilizing platform for offshore wind power single pile construction.

[0006] The pile stabilizing platform for offshore wind power single pile construction provided by the present application adopts the following technical solution:

[0007] A pile stabilizing platform for offshore wind power single pile construction includes a mounting frame, two pile grippers, and two buoyancy aids. The two pile grippers are arranged on the upper end of one side of the mounting frame and are spaced apart in the vertical direction. The two buoyancy aids are vertically arranged and are spaced apart in the horizontal direction on the lower end of the side of the mounting frame opposite the pile grippers.

[0008] By adopting the above technical solution, in actual application, the two pile grippers are cantilever structures, and the center of gravity of the pile stabilizing platform is offset during hoisting, causing the pile stabilizing platform to tilt when seated on the seabed. The two buoyancy aids on the same side of the pile grippers can generate buoyancy to move the center of buoyancy in the opposite direction of the tilt, i.e., to restore the center of gravity of the pile stabilizing platform, thereby avoiding the center of gravity of the pile stabilizing platform from being offset as much as possible.

[0009] Preferably, the buoyancy aid includes a cylinder, a first sealing cap, and a second sealing cap, and the first sealing cap and the second sealing cap are arranged at the two ends of the cylinder, respectively.

[0010] By adopting the technical scheme, the cylinder is in a sealed state by setting the cylinder, the first sealing cover and the second sealing cover, so that the buoyancy generated by the floatation assisting cylinder is uniform.

[0011] Preferably, the pile stabilizing platform further comprises a plurality of foam blocks, and the plurality of foam blocks are arranged in the cylinder and abut against each other.

[0012] By adopting the technical scheme, the plurality of foam blocks are arranged, the floatation assisting cylinder is easy to rust and leak after long-term use, and the plurality of foam blocks can fill the floatation assisting cylinder, so that the floatation assisting cylinder does not fail even if water leakage occurs, thereby improving the stability of work.

[0013] Preferably, the first sealing cover is threadedly connected to the upper end of the cylinder.

[0014] By adopting the technical scheme, the first sealing cover is threadedly connected to the upper end of the cylinder, so as to realize detachable connection between the first sealing cover and the cylinder, thereby facilitating replacement of the foam blocks.

[0015] Preferably, the floatation assisting cylinder further comprises an abutment plate and a spring, and the two ends of the spring are arranged on the abutment plate and the first sealing cover respectively and drive the abutment plate to abut against the uppermost foam block.

[0016] By adopting the technical scheme, the abutment plate abuts against the uppermost foam block under the driving of the spring, so that the foam blocks are more closely connected, thereby improving the sealing performance of the foam blocks on the cylinder.

[0017] Preferably, the floatation assisting cylinder further comprises a limiting column, and the limiting column is arranged on the lower side of the first sealing cover and the spring is sleeved on the limiting column.

[0018] By adopting the technical scheme, the limiting column is arranged to limit the spring, so as to avoid excessive bending and damage of the spring, thereby prolonging the service life of the spring.

[0019] Preferably, the floatation assisting cylinder further comprises a sealing ring sleeve, and the sealing ring sleeve is arranged between the first sealing cover and the abutment plate, and the spring is located in the sealing ring sleeve.

[0020] By adopting the technical scheme, the sealing ring sleeve is arranged to protect the spring, so as to avoid contact of the spring with seawater, thereby prolonging the service life of the spring.

[0021] Preferably, the floatation assisting cylinder further comprises a sealing gasket, and the sealing gasket is arranged on the lower side of the abutment plate.

[0022] By adopting the above technical solution and setting a sealing gasket, water can be prevented from entering the cylinder and coming into contact with the foam block as much as possible.

[0023] Preferably, the second sealing cap is detachably connected to the cylinder.

[0024] By adopting the above technical solution, a second sealing cap can be detachably connected to the cylinder body to facilitate the disassembly of the foam block.

[0025] Preferably, the buoyancy aid further includes a sealing ring, which is disposed in the lower end of the cylinder and abuts against the second sealing cover.

[0026] By adopting the above technical solution and setting a sealing ring, the sealing performance between the cylinder and the second sealing cover is improved.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By adding a floating cylinder structure, the uneven settlement caused by the eccentricity of the pile stabilization platform structure can be resolved, thus preventing the pile stabilization platform from tilting.

[0029] 2. By setting multiple foam blocks and filling the buoyancy aid cylinder, the problem of leakage caused by quality defects in the buoyancy aid cylinder, which prevents it from playing a balancing role, is solved.

[0030] 3. It can solve the problem that after the pile stabilizing platform has been submerged underwater for a long time, the auxiliary float will gradually fill with water due to leakage, and the water in the auxiliary float will not be able to flow out when the pile stabilizing platform is lifted out of the water, which will cause a significant increase in the weight of the platform and affect the lifting safety.

[0031] 4. By setting up a stop plate and a spring, the stop plate abuts against the topmost foam block under the drive of the spring, making the connection between the foam blocks tighter and improving the sealing performance of the foam blocks to the cylinder. Attached Figure Description

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application; the description and claims of this application as well as the above description of the drawings herein are not inclusive of all of the features of the application, and are subject to change and modification.

[0038] Reference herein to an "embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase that the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of other embodiments. It is explicitly contemplated that embodiments described herein can be combined with each other.

[0039] The following detailed description is made with reference to the accompanying drawings. Figures 1-4 The application is further described in detail.

[0040] The embodiments of the application disclose a pile stabilizing platform for offshore wind power single pile construction.

[0041] Embodiment 1:

[0042] With reference to Figure 1 and Figure 2 The pile stabilizing platform comprises a mounting frame 1, two pile grabbers 2 and two buoy 3, the mounting frame 1 is arranged in the shape of a rectangular frame body, the two pile grabbers 2 are fixedly connected to the upper end of one side of the mounting frame 1 through welding, and the two pile grabbers 2 are arranged in the vertical direction and are spaced apart, so that each pile grabber 2 protrudes from one side of the mounting frame 1, that is, the pile grabber 2 is a cantilever structure. The two buoy 3 are fixedly connected to the lower end of the side of the mounting frame 1 through welding, and the two buoy 3 are vertically arranged and are spaced apart in the horizontal direction.

[0043] In actual application, as the two pile grippers 2 are cantilever structures, the center of gravity of the pile stabilizing platform is prone to deviate when the pile stabilizing platform is hoisted by a single hook, which results in the inclination of the pile stabilizing platform when it is seated on the seabed. The two buoyancy aids 3 on the same side of the pile gripper 2 can generate corresponding buoyancy in the sea to move the center of buoyancy in the opposite direction of the inclination, so as to re-level the pile stabilizing platform, that is, to correct the center of gravity of the pile stabilizing platform, thereby avoiding the deviation of the center of gravity of the pile stabilizing platform as much as possible. In this way, the leveled pile stabilizing platform can provide a stable working plane for the sinking of the wind power foundation pile, so that the verticality control precision of the wind power foundation pile is higher, and the sinking quality control is improved.

[0044] In some embodiments, the buoyancy aid 3 comprises a cylinder 31, a first sealing cover 32 and a second sealing cover 33. The cylinder 31 is hollow and has openings at the upper and lower ends. The first sealing cover 32 is fixedly connected to the upper end of the cylinder 31, and the second sealing cover 33 is fixedly connected to the lower end of the cylinder 31, so that the cylinder 31 is in a sealed state to ensure that the buoyancy generated by the buoyancy aid 3 is uniform, thereby ensuring that the pile stabilizing platform is stably in a horizontal state.

[0045] In some embodiments, the pile stabilizing platform further comprises a plurality of foam blocks 4, which are placed in the cylinder 31 and abut each other between two adjacent foam blocks 4. In actual application, the buoyancy aid 3 is prone to rust and water leakage after long-term use and loses buoyancy. The plurality of foam blocks 4 can fill the buoyancy aid 3 to ensure that the buoyancy aid 3 will not fail even if it leaks water, thereby improving the stability of the work. At the same time, by arranging the plurality of foam blocks 4, it is not necessary to conduct a sealing test on the buoyancy aid 3, which can effectively reduce the construction period of the project.

[0046] The implementation principle of the embodiment is as follows: in actual application, as the two pile grippers 2 are cantilever structures, the center of gravity of the pile stabilizing platform is prone to deviate when the pile stabilizing platform is hoisted by a single hook, which results in the inclination of the pile stabilizing platform when it is seated on the seabed. The two buoyancy aids 3 on the same side of the pile gripper 2 can generate corresponding buoyancy in the sea to move the center of buoyancy in the opposite direction of the inclination, so as to re-level the pile stabilizing platform, that is, to correct the center of gravity of the pile stabilizing platform, thereby avoiding the deviation of the center of gravity of the pile stabilizing platform as much as possible. In this way, the leveled pile stabilizing platform can provide a stable working plane for the sinking of the wind power foundation pile, so that the verticality control precision of the wind power foundation pile is higher, and the sinking quality control is improved.

[0047] Embodiment 2:

[0048] Reference Figure 3 and Figure 4The embodiment is same as other structures of the embodiment 1, and different from the embodiment 1 in that the first sealing cover 32 is detachably connected to the upper end of the cylinder body 31. Specifically, the first sealing cover 32 is screwed into the upper end of the cylinder body 31, so as to open the cylinder body 31, thereby facilitating replacement of the foam blocks 4.

[0049] Referring to Figure 4 In some embodiments, the flotation aid cylinder 3 further comprises an abutting plate 34 and a spring 35. The upper end of the spring 35 is fixedly connected to the lower side of the first sealing cover 32, and the lower end of the spring 35 is fixedly connected to the upper side of the abutting plate 34. The spring 35 drives the abutting plate 34 to move downward. When the first sealing cover 32 is screwed into the cylinder body 31, the abutting plate 34 abuts against the uppermost foam block 4 under the driving of the spring 35, so that the connection between the foam blocks 4 is more compact, thereby improving the sealing performance of the plurality of foam blocks 4 to the cylinder body 31.

[0050] In some embodiments, the flotation aid cylinder 3 further comprises a limiting column 36. The limiting column 36 is fixedly connected to the lower side of the first sealing cover 32, and the upper end of the spring 35 is sleeved on the limiting column 36, so as to limit the spring 35 and avoid excessive bending of the spring 35, thereby prolonging the service life of the spring 35.

[0051] In some embodiments, the flotation aid cylinder 3 further comprises a sealing ring sleeve 37. The sealing ring sleeve 37 is a corrugated sleeve. One end of the sealing ring sleeve 37 is fixedly connected to the lower side of the first sealing cover 32, and the other end of the sealing ring sleeve 37 is fixedly connected to the upper side of the abutting plate 34. The spring 35 is located in the sealing ring sleeve 37, so as to protect the spring 35 and avoid contact of the spring 35 with seawater, thereby effectively delaying the rusting speed of the spring 35 and prolonging the service life of the spring 35.

[0052] In some embodiments, the flotation aid cylinder 3 further comprises a sealing gasket 38. The sealing gasket 38 is fixedly connected to the lower side of the abutting plate 34, so as to avoid water entering the cylinder body 31 and contacting the foam blocks 4, thereby prolonging the service life of the foam blocks 4.

[0053] In some embodiments, the second sealing cover 33 is detachably connected to the cylinder body 31. In the embodiment, the second sealing cover 33 is screwed into the lower end of the cylinder body 31. In other embodiments, the detachable connection can be plug-in connection, clamping connection, or the like, which is not limited in the present application. In this way, the foam blocks 4 can be easily detached.

[0054] In some embodiments, the flotation aid cylinder 3 further comprises a sealing ring 39. The sealing ring 39 is embedded in the lower end of the cylinder body 31. When the second sealing cover 33 is screwed into the cylinder body 31, the second sealing cover 33 abuts against the sealing ring 39, so as to improve the sealing performance between the cylinder body 31 and the second sealing cover 33 and avoid seawater entering the cylinder body 31 from between the cylinder body 31 and the second sealing cover 33.

[0055] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
