Detailed Implementation

[0021] In existing technologies, leveling is performed by using floating cranes for lifting or by using counterweights. However, when using floating cranes for leveling, it is easily affected by natural factors such as waves, tides, and wind, resulting in swaying and poor leveling accuracy. When using counterweights for leveling, the position of the counterweights needs to be adjusted frequently, resulting in low leveling efficiency.

[0022] To address the aforementioned technical problems, this utility model provides a bottom-mounted positioning device, including a support frame, a positioning frame, and a leveling part. The support frame includes multiple columns, each column having a first end for insertion into the seabed and a second end for protruding above the water surface. The positioning frame is horizontally mounted on the columns. The leveling part is located near the first end of the columns. The leveling part includes an adjusting plate and at least one telescopic component. The adjusting plate has a through hole through which the first end of the columns can pass, and the adjusting plate can rotate around the columns. One end of the telescopic component is connected to the columns, and the other end of the telescopic component is connected to the adjusting plate. The telescopic component is used to adjust the tilt angle between the adjusting plate and the columns, thereby adapting to different seabed conditions and achieving leveling in multiple scenarios, thus improving leveling efficiency and accuracy.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] The bottom-mounted positioning device provided in this utility model embodiment will be described in detail below with reference to specific embodiments.

[0025] Figure 1 This is a front view of a bottom-mounted positioning device provided in an embodiment of this utility model. Figure 2 This is a top view of a bottom-mounted positioning device provided in an embodiment of this utility model. Figure 1 and Figure 2 As shown, the bottom-mounted positioning device 100 includes: a positioning frame 110, a support frame 120, and a leveling part 130. The support frame 120 includes multiple columns 121, a first end for inserting into the seabed and a second end for protruding above the water surface. The positioning frame 110 is horizontally arranged on the multiple columns 121. The leveling part 130 is arranged near the first end of the columns 121. The leveling part 130 includes an adjusting plate 131 and at least one telescopic component 132. The adjusting plate 131 has a through hole through which the first end of the columns 121 can pass. The adjusting plate 131 can rotate around the columns 121. One end of the telescopic component 132 is connected to the columns 121, and the other end of the telescopic component 132 is connected to the adjusting plate 131. The telescopic component 132 is used to adjust the tilt angle between the adjusting plate 131 and the columns 121.

[0026] In this embodiment, the positioning frame 110 is mainly used to provide a precise positioning reference to ensure the accurate positioning and stability of the wind power equipment during installation. The multiple columns 121 in the support frame 120 are used to ensure the precise position of the positioning frame 110 and to provide support for the positioning frame 110 to prevent it from slipping or overturning. The leveling plate 131 in the leveling part 130 increases the contact area between the column 121 and the seabed surface, thereby reducing the concentration of local stress and avoiding insufficient leveling accuracy due to the settlement and deformation of the column 121. The telescopic component 132 connects the column 121 and the leveling plate 131 and is used to adjust the tilt angle between the leveling plate 131 and the column 121 to adapt to seabed surfaces with different tilt angles, thus ensuring the accuracy of leveling.

[0027] In this embodiment, one end of the telescopic component 132 of the bottom-mounted positioning device 100 is hinged to the column 121, and the other end of the telescopic component 132 is hinged to the adjusting plate 131.

[0028] In this embodiment, a hinge is a mechanical connection method that connects two components, allowing the two hinged components to rotate or swing relative to each other within a certain range. It has a simple design, low manufacturing and maintenance costs, and is easy to maintain. One end of the telescopic component 132 is hinged to the column 121, and the other end of the telescopic component 132 is hinged to the adjusting plate 131, so that the adjusting plate 131 can rotate freely around the axis of the column 121 to adapt to seabed surfaces with different flatness, thereby improving the applicability and maintainability of the bottom-sitting positioning device 100.

[0029] In this embodiment, the telescopic component 132 of the bottom-mounted positioning device 100 includes a fixed rod and a telescopic rod; the telescopic rod is slidably connected to the fixed rod, and the telescopic rod can rotate around the axis of the fixed rod; the telescopic rod is connected to the column 121; and the fixed rod is connected to the adjusting plate 131.

[0030] In this embodiment, the telescopic rod in the telescopic assembly 132 is used to adjust the length, absorb deformation and displacement within a preset range, reduce stress concentration on the column 121, and improve the stability and durability of the bottom-mounted positioning device 100; the fixed rod in the telescopic assembly 132 is used to provide rigid support, ensuring the stability of the adjusting plate 131. At the same time, the adjusting plate 131 and the column 121 can be flexibly adjusted through the fixed rod and the telescopic rod to achieve precise leveling of the bottom-mounted positioning device 100.

[0031] For example, the telescopic component 132 can refer to a hydraulic cylinder. The hydraulic cylinder monitors the tilt angle of the column 121 and the adjusting plate 131 in real time through a tilt sensor and transmits the data to the controller. The controller determines the current tilt state based on a preset balance standard. Based on the tilt angle and the preset balance standard, the controller calculates the required adjustment of the hydraulic cylinder stroke and pressure. The controller generates a corresponding control signal and sends it to the hydraulic valve. Upon receiving the control signal, the hydraulic valve adjusts the flow and direction of the hydraulic oil to drive the hydraulic cylinder. The hydraulic cylinder adjusts the height of the column 121 and the angle of the adjusting plate 131 by telescoping or swinging. During the leveling process, the sensor continuously monitors the state of the column 121 and the adjusting plate 131 and feeds the data back to the controller. Based on the real-time data, the controller dynamically adjusts the opening and direction of the hydraulic valve for fine leveling until the precise leveling of the bottom-mounted positioning device 100 is achieved.

[0032] In this embodiment, the bottom-mounted positioning device 100 further includes a first hinge seat, through which the telescopic rod is connected to the column 121. The bottom-mounted positioning device 100 also includes a second hinge seat, through which the fixing rod is connected to the adjusting plate 131.

[0033] In this embodiment, both the first hinge seat and the second hinge seat are fixed hinge supports. The telescopic rod is connected to the column 121 through the first hinge seat, and the fixed rod is connected to the adjusting plate 131 through the second hinge seat, so that the adjusting plate 131 can rotate freely around the axis of the column 121 to adapt to seabed surfaces with different flatness and improve the applicability of the bottom-sitting positioning device 100.

[0034] Optionally, in this embodiment, the leveling part 130 includes a plurality of telescopic components 132, which are evenly arranged along the circumference of the column 121.

[0035] In this embodiment, for example, such as Figure 3 As shown, the leveling part 130 is evenly arranged with eight telescopic components 132 along the circumference of the column 121, which can significantly improve the leveling effect, enhance the positioning accuracy, and provide a uniform force distribution, thereby enhancing the stability of the leveling part 130.

[0036] Optionally, in this embodiment, the leveling part 130 includes two telescopic components 132, which are arranged radially opposite to each other along the column 121.

[0037] In this embodiment, for example, such as Figure 4 As shown, the leveling part 130 is arranged radially opposite to the column 121 by two telescopic components 132. While ensuring the stability of the leveling part 130, the number of telescopic components 132 can be reduced, thus saving costs.

[0038] In this embodiment, the bottom-mounted positioning device 100 further includes a connecting column 113, through which multiple columns 121 are connected. This ensures the stability of the multiple columns 121 and avoids misalignment that could lead to inaccurate positioning. The positioning frame 110 includes a horizontal support 111 and a sleeve 112; the horizontal support 111 is mounted on the column 121; the sleeve 112 is located at the end of the horizontal support 111, and has a columnar space inside for inserting engineering piles 140.

[0039] In this embodiment, the horizontal support 111 provides support and stability for the positioning frame 110, ensuring the horizontal positioning of the positioning frame 110. The sleeve 112 is located at the end of the horizontal support 111 and has a columnar space inside for inserting the engineering pile 140. The engineering pile 140 is used to bear the load of other components or structures to ensure the stability and safety of the seated positioning device 100. The sleeve 112 provides precise guidance for the engineering pile 140, avoiding the engineering pile 140 from shifting due to lateral force, which would lead to inaccurate positioning.
