Detailed Description of the Embodiments

[0029] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0030] The terms "first", "second", "third", "fourth", etc. (if any) in the specification, claims and above-mentioned drawings of the present application are used to distinguish similar objects and do not necessarily describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present application described herein, for example, can be implemented in an order other than those illustrated or described herein.

[0031] In the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations, or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0032] A single-pile foundation is the foundation of an offshore wind power project and is used to support a single wind turbine tower. A single-pile foundation is usually a steel pipe pile driven vertically into the seabed, and its main purpose is to transfer the structural load of the wind turbine to the seabed formation and resist the lateral forces caused by wind and waves, ensuring the stable operation of the wind turbine generator set under various marine environmental conditions. The diameter of a single-pile foundation is generally in the range of several meters, and the length is generally in the range of dozens of meters to hundreds of meters, depending on the seabed geological conditions and the required bearing capacity.

[0033] When designing the foundation of a wind power generator set, due to factors such as water depth, geological conditions, the weight and size of the wind power generator set, etc., different-sized single-pile foundations will be adopted for the foundation of the wind power generator set, such as single-pile foundations with different lengths. The applicant found that since the jacking device is fixed at a specific position on the pile stabilization platform, then when constructing different-length single-pile foundations or at different construction stages of the same single-pile foundation, these jacking devices may not be able to effectively contact the single-pile foundation, thus unable to adjust it properly. For example, for shorter or longer single-pile foundations, the original jacking device cannot provide enough adjustment range, resulting in the inability to precisely adjust the position of the single-pile foundation, thereby affecting the construction efficiency of the single-pile foundation. As described in the above situation, adjusting the installation position of the jacking device for different-length single-pile foundations affects the use efficiency of the jacking device.

[0034] The single-pile foundation adjusting device and pile stabilization platform provided by the present application aim to solve the above technical problems in the prior art.

[0035] The following will specifically describe the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems with specific embodiments. These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0036] Please refer to Figures 1 to 6, the single-pile foundation adjustment device provided by the embodiments of the present application includes a positioning cylinder 100 and at least two adjustment mechanisms 200. The at least two adjustment mechanisms 200 are arranged at intervals along the circumferential direction of the positioning cylinder 100 inside the positioning cylinder 100. The adjustment mechanism 200 includes a pushing component 210 and a first driving member 220. The pushing component 210 is rotatably connected to the inner peripheral wall of the positioning cylinder 100, and the first driving member 220 is fixedly connected to the inner peripheral wall of the positioning cylinder 100. The output end of the first driving member 220 is connected to the pushing component 210 to adjust the pitching angle of the pushing component 210. Among them, the pushing component 210 is used to push the single-pile foundation in the direction towards the center of the positioning cylinder 100.

[0037] The positioning cylinder 100 defines the installation area of the single-pile foundation and at the same time serves as the installation base for the pushing component 210 and the first driving member 220. The positioning cylinder 100 is a cylindrical structure, and its inner diameter is slightly larger than the outer diameter of the single-pile foundation, so that the single-pile foundation can be driven into the seabed from top to bottom within the positioning cylinder 100.

[0038] There are at least two adjustment mechanisms 200. The at least two adjustment mechanisms 200 can form at least two-point supports around the single-pile foundation, which helps to balance the weight of the single-pile foundation and avoid excessive single-point force, resulting in tilting or offset of the adjustment mechanism 200. Multiple adjustment mechanisms 200 can act together on the single-pile foundation to ensure its stability in multiple directions, thereby improving the stability during the construction process of the single-pile foundation.

[0039] The adjustment mechanism 200 includes a pushing component 210 and a first driving member 220. The pushing component 210 can push or abut against the single-pile foundation, thereby adjusting the verticality and horizontality of the single-pile foundation, or keeping the single-pile foundation in a vertical posture so that the verticality of the single-pile foundation meets the requirements. The first driving member 220 can change the pitching angle of the pushing component 210, so that the pushing component 210 can be adjusted to a suitable position according to the length of the single-pile foundation, so that the pushing component 210 can be applicable to single-pile foundations of different lengths or single-pile foundations at different installation stages in the future. At the same time, when the first driving member 220 is arranged below the pushing component 210, the first driving member 220 can support the pushing component 210, making the pushing process of the pushing component 210 on the single-pile foundation smooth, which is beneficial to improving the structural stability of the pushing component 210. Exemplarily, the first driving member 220 is a driving device such as an electric motor or a hydraulic cylinder, and the output end of the first driving member 220 is rotatably connected to the first driving member 220.

[0040] In actual use, first, according to the length of the single-pile foundation, the first driving member 220 is activated to adjust the pitching angle of the pushing component 210 so that the pushing component 210 reaches a position where it can push the single-pile foundation; then, in combination with the plumbness requirement and the actual deviation of the single-pile foundation, the pushing component 210 adjusts the single-pile foundation to meet the construction requirements.

[0041] Therefore, for the single-pile foundation adjusting device provided in the embodiment of the present application, by adjusting the pitching angle of the pushing component 210 through the first driving member 220, it can adapt to the installation requirements of single-pile foundations of different lengths or adapt to the installation requirements at different installation stages of the single-pile foundation, which is beneficial to improving the use efficiency of the adjusting mechanism and the construction efficiency of the single-pile foundation.

[0042] In an alternative embodiment, please refer to Figure 3 and Figure 4 , the pushing component 210 includes a fixed seat 211, a pushing member 212 and a second driving member 213. The fixed seat 211 is rotatably connected to the inner peripheral wall of the positioning cylinder 100. The pushing member 212 is slidably connected to the fixed seat 211. The second driving member 213 is arranged on the fixed seat 211, and the output end of the second driving member 213 is connected to the pushing member 212 so that the pushing member 212 pushes the single-pile foundation along the direction towards the center of the positioning cylinder 100.

[0043] The fixed seat 211 and the inner peripheral wall of the positioning cylinder 100 can be connected by a hinged manner, so that the whole pushing component 210 can adjust its position through the fixed seat 211, thereby realizing the adjustment of the pitching angle. The pushing member 212 is slidably connected to the fixed seat 211, so that the pushing member 212 can move along the fixed seat 211 to push the single-pile foundation. Among them, the second driving member 213 is arranged on the fixed seat 211, and its output end is connected to the pushing member 212, which is used to drive the pushing member 212 to extend and retract along the direction towards the center of the positioning cylinder 100 to adjust the levelness or plumbness of the single-pile foundation.

[0044] During use, the single-pile foundation is located inside the positioning cylinder 100, and the pushing component 210 of the adjusting mechanism 200 is in the initial position. First, by activating the first driving member 220 to drive the pushing component 210 to rotate until the pushing component 210 contacts the single-pile foundation; then, by driving the pushing member 212 to move along the direction towards the center of the positioning cylinder 100 through the second driving member 213, the pushing member 212 can perform an appropriate pushing action according to the length of the single-pile foundation to ensure that the plumbness of the single-pile foundation meets the requirements.

[0045] Exemplarily, the second driving member 213 is a driving device such as a hydraulic cylinder, a piston cylinder, a telescopic motor, etc.

[0046] In an alternative embodiment, please refer to Figure 5 and Figure 6, an installation seat 230 is provided on the inner peripheral wall of the positioning cylinder 100. The installation seat 230 is provided with an installation groove 233. One end of the fixed seat 211 away from the center of the positioning cylinder 100 is rotatably connected to the installation groove 233.

[0047] An installation groove 233 is provided in the installation seat 230. The end of the fixed seat 211 away from the center of the positioning cylinder 100 is rotatably installed in the installation groove 233. It can be understood that the installation groove 233 is a groove structure, and the groove wall of the installation groove 233 can limit the end of the fixed seat 211. During the adjustment of the pushing component 210, the installation groove 233 can reduce the offset or swing of the fixed seat 211 in directions other than the rotation direction, thereby being beneficial to improving the stability of the pushing component 210 and ensuring that the pushing component 210 remains stable when adjusting the pitching angle. Optionally, the installation seat 230 can design the shape of the installation groove 233 according to the pitching angle adjustment range of the pushing component 210 and the shape of the end of the fixed seat 211; the installation seat 230 and the fixed seat 211 are connected by a rotating shaft, so that the pushing component 210 can rotate within a certain angle range as needed to adapt to single pile foundations of different lengths.

[0048] Exemplarily, the installation seat 230 is in an L shape or a U shape, one side of which is welded and fixed to the peripheral wall of the positioning cylinder 100, and the other side is provided with an installation groove 233. The installation groove 233 can be a V-shaped groove, and its width and depth need to match the end of the fixed seat 211 to ensure that the fixed seat 211 can rotate smoothly in the installation groove 233.

[0049] In an optional embodiment, the installation seat 230 includes a first limiting portion 231 and a second limiting portion 232 provided in the installation groove 233. The first limiting portion 231 and the second limiting portion 232 are arranged at intervals along the circumferential direction of the positioning cylinder 100. The fixed seat 211 is located between the first limiting portion 231 and the second limiting portion 232, so that the first limiting portion 231 and the second limiting portion 232 can limit the fixed seat 211 in the circumferential direction of the positioning cylinder 100.

[0050] The fixed seat 211 is arranged between the first limiting portion 231 and the second limiting portion 232. The first limiting portion 231 and the second limiting portion 232 can effectively limit the offset of the fixed seat 211 in the circumferential direction of the positioning cylinder 100, improve the stability of the entire adjustment structure, reduce the situation of adjustment inaccuracy caused by lateral offset, help improve the adjustment accuracy of the pushing component 210, and ensure that the single pile foundation can accurately reach the required verticality or levelness. The first limiting portion 231 and the second limiting portion 232 are usually protruding structures installed on the installation seat 230, and can be bumps or baffles made of metal, etc. Exemplarily, the first limiting portion 231 and the second limiting portion 232 are extension parts of the groove wall of the installation groove 233.

[0051] In an alternative embodiment, a chute is provided inside the fixed seat 211, and the pushing member 212 is disposed in the chute and slidably connected to the chute.

[0052] The chute is provided inside the fixed seat 211. The pushing member 212 is arranged in the chute and is in sliding fit therewith. The pushing member 212 is slidably connected to the chute. The main function of the chute is to guide the pushing member 212 to move along a predetermined direction, which helps to improve the movement accuracy of the pushing member 212, thereby improving the adjustment accuracy of the entire adjustment device. Through the cooperation of the chute and the pushing member 212, the error caused by unstable movement is reduced, which is beneficial to improving the stability of the pushing member 212 during movement. At the same time, the connection structure between the pushing member 212 and the fixed seat 211 is simplified through the chute structure, making it easier for the pushing member 212 to move on the fixed seat 211.

[0053] Exemplarily, the chute is a groove provided inside the fixed seat 211, and its shape and size match those of the pushing member 212, so that the pushing member 212 can move smoothly in the chute. The chute can be in a long strip shape, and its width and depth need to match those of the pushing member 212 to ensure that the pushing member 212 can move smoothly in the chute.

[0054] In an alternative embodiment, a guide wheel 214 is provided at one end of the pushing member 212 facing the center of the positioning cylinder 100, and the guide wheel 214 is rotatably connected to the pushing member 212.

[0055] The guide wheel 214 is in rolling fit with the single-pile foundation, reducing the direct contact between the pushing member 212 and the single-pile foundation, thereby reducing the frictional resistance when the pushing member 212 contacts the single-pile foundation, making the pushing process smoother and more stable. Since the frictional force between the guide wheel 214 and the single-pile foundation is reduced, the wear and scratch of the pushing member 212 on the single-pile foundation and the wear of the pushing member 212 itself are reduced, which is beneficial to ensuring the structural integrity of the single-pile foundation itself and extending the service life of the pushing member 212.

[0056] Exemplarily, the guide wheel 214 can be made of wear-resistant materials such as high-strength plastics or metals. The guide wheel 214 can be designed in a circular or other shape, and its size and shape need to match those of the pushing member 212 and the single-pile foundation to ensure good contact and rolling performance. The guide wheel 214 is located at one end of the pushing member 212 facing the center of the positioning cylinder 100 and is rotatably connected to the pushing member 212.

[0057] In an alternative embodiment, the single-pile foundation adjustment device further includes a controller, and the controller is electrically connected to the adjustment mechanism 200.

[0058] The controller can achieve the automatic control of the adjusting mechanism 200, reduce the need for manual intervention, and improve work efficiency. Moreover, the controller can precisely control the actions of the adjusting mechanism 200 to ensure that the verticality or horizontality of the single-pile foundation meets strict requirements. During actual use, the controller is electrically connected to the adjusting mechanism 200, and can real-time monitor the data during the adjustment process, such as the position of the pushing member 212, the magnitude of the pushing force, etc., and adjust the actions of the first driving member 220 and the second driving member 213 according to these data to ensure the precise adjustment of the single-pile foundation.

[0059] Exemplarily, the controller includes electronic components such as a central processing unit (CPU), a memory, an input-output interface, etc., which are used to receive the usage status information of the first driving member 220 and the second driving member 213, as well as the plumbness information and horizontality information of the single-pile foundation, and process the above information to issue corresponding instructions so that the single-pile foundation meets the construction requirements.

[0060] In an alternative embodiment, please refer to Figure 1 and Figure 2 , the positioning cylinder 100 includes at least two cylinders 101, and the at least two cylinders 101 are sequentially arranged along the circumferential direction of the positioning cylinder 100, and two adjacent cylinders 101 are detachably connected.

[0061] The positioning cylinder 100 is composed of a plurality of detachably cylinders 101. Through the detachably connected cylinders 101, the cylinders 101 can be reused in different projects, reducing the equipment cost. Decomposing the positioning cylinder 100 into a plurality of cylinders 101 can simplify the transportation process, facilitate transportation to the construction site, and also facilitate on-site installation. Moreover, the design of the detachably connected cylinders 101 makes it more convenient to maintain or replace damaged cylinders 101. In addition, the positioning cylinder 100 can adopt different numbers or replace cylinders 101 of different sizes according to the single-pile foundation of different diameters to adapt to single-pile foundations of different sizes.

[0062] Exemplarily, between two adjacent cylinders 101, connection methods such as high-strength bolts and flanges are adopted to ensure the stability and reliability of the connection.

[0063] Furthermore, a locking device 102 is provided between two adjacent cylinders 101. The locking device 102 is arranged on one of the cylinders 101, and the output end of the locking device 102 is arranged on the other cylinder 101.

[0064] The locking device 102 can further improve the connection firmness between two adjacent cylinders 101, prevent loosening or separation during use, reduce potential safety hazards caused by unstable connection between the cylinders 101, and is beneficial to ensuring that the positioning cylinder 100 maintains a good working state in a harsh marine environment.

[0065] Exemplarily, the locking device 102 is a mechanical locking mechanism, such as a snap or a bolt, or can also be a hydraulically or electrically driven locking mechanism, such as a hydraulic cylinder or a telescopic motor.

[0066] On the other hand, the present application also provides a pile stabilizing platform, which includes a platform body and the above single-pile foundation adjusting device. The single-pile foundation adjusting device is arranged on the platform body to adjust the single-pile foundation during the installation process. It can be understood that this pile stabilizing platform has the beneficial effects of any of the above embodiments, which will not be elaborated here one by one.

[0067] Those skilled in the art will readily conceive of other embodiments of the present application after considering the specification and practicing the utility model disclosed herein. The present application is intended to cover any variations, uses, or adaptations of the present application, which follow the general principles of the present application and include known common knowledge or conventional technical means in the technical field not disclosed in the present application.
