[0041] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0042] In the construction of wind turbine generators, the installation of the foundation anchor cage is a crucial step. The stability of the foundation anchor cage directly affects the overall installation quality and subsequent operational safety of the wind turbine generator. This installation process typically involves several complex steps, including the installation of the lower anchor plate, the assembly of the anchor bolts, the installation of the upper anchor plate, and final adjustment and fixing. Specifically, when installing the lower anchor plate, a crane is needed to precisely position it, and the levelness and concentricity of the support bolts are adjusted manually. The anchor bolt assembly stage requires precise placement of the anchor bolts, and manual operation is used to ensure the verticality of the anchor bolts and the integrity of the threads. The installation of the upper anchor plate requires the cooperation of a crane and manual labor to align the anchor bolts with the lower anchor plate, ensuring the alignment accuracy of the two anchor plates.

[0043] However, existing installation methods rely heavily on manual labor and multiple adjustments. Firstly, during installation, operators need to repeatedly adjust the position of the support bolts to ensure the anchor plate is precisely level, and ensure concentricity through visual inspection and manual measurement. Although mechanical equipment such as cranes is used to assist the work, the precision of each step is highly dependent on manual labor and easily affected by the skill level of on-site personnel and environmental factors. Because each step requires manual measurement and fine-tuning, the installation process is exceptionally lengthy. Manual operation not only increases construction time but may also introduce errors, reducing overall construction efficiency.

[0044] Further analysis reveals that existing construction methods involve highly repetitive steps, and the precision adjustments required during installation rely almost entirely on manual control, leading to low construction efficiency and a high risk of errors. Furthermore, the installation and subsequent adjustments of anchor bolts, especially in large-scale wind power projects, often require multiple inspections and corrections to ensure that each component meets design requirements.

[0045] Therefore, the biggest technical problem with existing technologies lies in the low installation and construction efficiency during the installation of anchor bolt cages for wind turbine foundations. This embodiment addresses the issues of low efficiency, poor accuracy, and long construction cycles exposed in existing technologies. It proposes an anchor plate centering and leveling device, which achieves high-precision centering and leveling during anchor plate installation through a combined design of a base, a level detection unit, and a laser emitting unit. The base quickly and securely fixes the device to the preset installation point on the anchor plate. The level detection unit monitors the horizontal status of the device in real time, ensuring that the anchor plate's levelness meets requirements. The laser emitting unit precisely adjusts the emission angle of the laser emitter through an angle adjustment mechanism, directing the laser towards the preset target position, thereby achieving precise centering of the anchor plate. This device features a simple structure, convenient operation, and high adjustment accuracy, significantly improving construction efficiency and reducing errors from manual operation.

[0046] like Figure 1 As shown, this embodiment provides an anchor plate alignment and leveling device, including:

[0047] The base portion 100 is used to fix the centering and leveling device to the preset mounting point of the anchor plate.

[0048] In this embodiment, the centering and leveling device can be used for the installation of anchor plates. The anchor plate can be either the upper or lower anchor plate in the wind turbine foundation anchor cage. Specifically, the wind turbine foundation anchor cage is a structure used to fix components such as the wind turbine tower and blades. The anchor cage can be composed of reinforcing bars, anchor bolts, anchor plates, and concrete, serving to support and stabilize the wind turbine. The anchor cage is connected to the foundation ground via anchor bolts, ensuring the entire unit can be stably fixed to the ground and withstand wind and environmental pressure. The lower anchor plate is located at the bottom of the wind turbine foundation anchor cage and is a crucial supporting structure for the entire anchor cage. The lower anchor plate is fixed to the underground foundation or concrete structure via anchor bolts, ensuring the stability of the anchor cage. The lower anchor plate is designed to withstand the weight of the tower and upper anchor plate, as well as the stress generated by wind. The lower anchor plate can have multiple preset installation points, facilitating the installation and adjustment of the centering and leveling device, thereby ensuring the accuracy and stability of the entire foundation system. The upper anchor plate is another component of the wind turbine foundation anchor cage, located at the top of the cage. It connects to the lower anchor plate via anchor bolts, securing them together to form a stable foundation structure. The upper anchor plate is designed to withstand the weight of the tower and other components while providing sufficient strength and stability. It can also be equipped with multiple pre-set mounting points to facilitate the installation and adjustment of leveling devices, ensuring the accuracy and stability of the entire foundation system.

[0049] In this embodiment, the anchor plate can also be an anchor plate in the building foundation.

[0050] In this embodiment, the anchor plate can also be an anchor plate in a bridge foundation.

[0051] In this embodiment, the anchor plate can also be an anchor plate in the foundation of an offshore platform.

[0052] In this embodiment, the base portion 100 can be the base of the centering and leveling device, used to fix the centering and leveling device to a preset mounting point on the anchor plate. Specifically, the base portion 100 can be a flat cylindrical shape, a cube shape, or a cuboid shape, etc. The base portion 100 can also be a magnetic base that can be directly attached to the preset mounting point on the anchor plate.

[0053] In this embodiment, the bottom of the base portion 100 may be provided with a threaded fixing structure, which can be fastened to the anchor plate by means of threads and screw holes.

[0054] In this embodiment, the bottom of the base portion 100 may be provided with an absorbent adhesive structure, that is, a layer of highly viscous adhesive material (such as double-sided tape) may be provided on the bottom surface of the base portion 100, and the base portion 100 may be fixed to the anchor plate by adhesive.

[0055] A level detection unit 200, which is fixed above the base unit 100, is configured to indicate the level status of the centering and leveling device.

[0056] In this embodiment, the horizontal detection unit 200 can be fixedly disposed above the base unit 100, that is, on the upper surface of the base unit 100.

[0057] In this embodiment, the level detection unit 200 can be an electronic level sensor. An electronic level sensor provides digital level detection. Through its built-in sensor, the electronic level sensor can measure the level of the device in real time and display the specific deviation value. This sensor is more accurate than a traditional bubble level and is unaffected by environmental factors (such as vibration and temperature changes), making it suitable for construction applications requiring high precision.

[0058] In this embodiment, the horizontal detection unit 200 may be a photoelectric sensor.

[0059] In this embodiment, the level detection unit 200 may be a bubble level sensor.

[0060] In this embodiment, the level detection unit 200 can be one or more leveling bubbles. These one or more leveling bubbles can be directly fixed to the upper surface of the base unit 100 to indicate the level status of the centering and leveling device.

[0061] The laser emitting unit is fixed above the base 100 and includes an angle adjustment mechanism 310 and a laser emitter 320. The angle adjustment mechanism 310 is configured to adjust the emission angle of the laser emitter 320 so that the laser is directed to a preset target position.

[0062] In this embodiment, the angle adjustment mechanism 310 can be directly fixed above the base portion 100, for example, fixed to the upper surface of the base portion 100.

[0063] Specifically, in this case, the angle adjustment mechanism 310 can be a rotating bracket structure. Specifically, this rotating bracket structure may include a rotating bracket fixed above the base portion 100 (e.g., by bolts or welding). This rotating bracket is connected to the laser emitter 320 via a rotating shaft. The laser emitter 320 can rotate freely around the rotating shaft, and the emission angle of the laser is adjusted by rotating the bracket.

[0064] In some embodiments, the angle adjustment mechanism 310 can be a sliding adjustment structure. Specifically, the sliding adjustment structure may include a sliding guide rail and a slider assembly. The sliding guide rail is fixed above the base portion 100, and the slider assembly can slide along the guide rail. The laser emitter 320 is fixed to the slider assembly, and the laser emission angle is changed by the movement of the slider.

[0065] In this embodiment, the angle adjustment mechanism 310 can also be fixed above the base portion 100 by other components (e.g., a support portion 400), for example, fixed to the upper surface of the base portion 100. Specifically, the angle adjustment mechanism 310 can be a support arm, one end of which can be rotatably connected to the support portion 400 via a pivot to achieve rotation. The other end of the support arm can be fixedly connected to the laser emitter 320, or it can be movably connected to the laser emitter 320 (e.g., the other end of the support arm can be provided with a plug-in kit to achieve pluggable connection of the laser emitter 320, etc.).

[0066] In this embodiment, the laser emitter 320 may be a semiconductor laser.

[0067] In this embodiment, the laser emitter 320 may be a solid-state laser.

[0068] In this embodiment, the centering and leveling device may further include:

[0069] A scale is vertically mounted on the top surface of the base 100. This scale is used to achieve high-precision adjustment of the overall levelness of the upper and lower anchor plates. Specifically, the scale is vertically fixed to the top surface of the base 100, with its scale lines distributed vertically to receive horizontal laser illumination and display specific values. At the construction site, a horizontal laser emitting device can be installed at the center of the upper and lower anchor plates (usually hollow ring structures) or at other predetermined locations. The height of the horizontal laser emitting device is adjusted so that the emitted horizontal laser light can illuminate the vertical scales of each alignment and leveling device. After the height of the horizontal laser emitting device is adjusted, the laser illumination values ​​on each vertical scale are observed. If the values ​​on all scales are consistent, it indicates that the overall levelness of the upper and lower anchor plates has reached the design accuracy. If the values ​​are inconsistent, the values ​​on each scale are made consistent by fine-tuning the support bolts or other adjustment mechanisms of the lower anchor plate, thereby achieving high-precision leveling of the lower anchor plate.

[0070] In this embodiment, the scale lines of the ruler can be evenly distributed vertically, and the unit can be millimeters (mm) or other suitable units of measurement to facilitate accurate reading of laser irradiation values. The scale lines can be printed, engraved, or otherwise marked on the surface of the ruler. The ruler can be fixed to the top surface of the base 100 by bolts, clips, or magnetic attraction to ensure it does not loosen or shift during construction. The ruler can be made of metal, plastic, or other high-precision materials to ensure its durability and measurement accuracy.

[0071] This embodiment provides an anchor plate alignment and leveling device. Through the combined design of a base 100, a level detection unit 200, and a laser emitting unit, high-precision alignment and leveling are achieved during anchor plate installation. The base 100 quickly and securely fixes the device to the preset installation point on the anchor plate. The level detection unit 200 monitors the horizontal status of the device in real time, ensuring the anchor plate's levelness meets requirements. The laser emitting unit precisely adjusts the emission angle of the laser emitter 320 via an angle adjustment mechanism 310, directing the laser towards the preset target position, thereby achieving precise anchor plate alignment. This device features a simple structure, convenient operation, and high adjustment precision, significantly improving construction efficiency and reducing errors from manual operation. It is suitable for various scenarios such as wind turbine generator sets, building foundations, and bridge foundations, providing an efficient and reliable solution for anchor plate installation.

[0072] In some embodiments, the centering and leveling device further includes:

[0073] The support part 400 is fixedly connected at its bottom to the top surface of the base part 100. One end of the angle adjustment mechanism 310 is hinged to the support part 400 through a rotating shaft mechanism. The other end of the angle adjustment mechanism 310 is provided with a laser emitter receiving unit, which is used to install the laser emitter 320.

[0074] In this embodiment, the support portion 400 may be cuboid in shape, with its bottom fixedly connected to the top surface of the base portion 100. The side of the support portion 400 may have a mounting groove to accommodate the rotating shaft mechanism, allowing the angle adjustment mechanism 310 to rotate flexibly. A vertical scale may also be fixedly connected to the side of the support portion 400 to receive external horizontal laser illumination and display specific values, thereby achieving fine-tuning of the levelness. The support portion 400 may be made of metal (such as aluminum alloy) or high-strength plastic to ensure its structural strength and durability.

[0075] In this embodiment, the rotating shaft mechanism can be a fixable bolt. Specifically, the rotating shaft mechanism includes a bolt and a nut. The bolt passes through the connection between the support 400 and the angle adjustment mechanism 310 and is fixed by the nut. The tightness of the bolt can be adjusted to achieve the rotation and fixation of the angle adjustment mechanism 310.

[0076] In this embodiment, the rotating shaft mechanism can be a ball joint structure.

[0077] In this embodiment, the rotating shaft mechanism can be a damped rotating shaft structure.

[0078] In this embodiment, the laser emitter receiving unit can be a laser emitter fixing slot. Specifically, the laser emitter fixing slot can be an open slot-shaped structure, with a groove or buckle inside that matches the shape of the laser emitter 320. The laser emitter 320 can be directly inserted into the fixing slot and fixed by bolts, buckles, or magnetic devices.

[0079] In this embodiment, the laser emitter housing unit can be a pluggable kit structure.

[0080] In this embodiment, the laser emitter housing unit can be a clamping and fixing structure.

[0081] This embodiment further optimizes the structural design of the angle adjustment mechanism 310 by adding a support part 400. The support part 400 is fixed to the top surface of the base part 100 and is hinged to the angle adjustment mechanism 310 through a rotating shaft mechanism, allowing the laser emitter housing unit to flexibly adjust the emission angle of the laser emitter 320. This design not only enhances the stability and adjustment accuracy of the device but also simplifies the installation and adjustment process of the laser emitter 320, improving construction efficiency. Simultaneously, the introduction of the support part 400 enables the device to adapt to more complex construction environments, providing more reliable and efficient technical support for the alignment and leveling of the anchor plate.

[0082] In some embodiments, the support 400 is a cuboid or cube-shaped structure, and a mounting groove is provided on one side of its vertical side for accommodating the rotating shaft mechanism.

[0083] This embodiment significantly improves the stability and adjustment flexibility of the device by designing the support part 400 as a cuboid or cube-shaped structure and providing a mounting groove on one of its vertical sides to accommodate the rotating shaft mechanism. The mounting groove design allows the rotating shaft mechanism to be securely fixed within the support part 400, while ensuring smooth and precise rotation of the angle adjustment mechanism 310. This structure not only simplifies the assembly process but also enhances the overall rigidity and durability, making it suitable for various complex construction environments. Furthermore, the cuboid or cube-shaped support part 400 facilitates integration with other components (such as rulers, angle gauges, etc.), further improving the adjustment accuracy and ease of operation of the centering and leveling device.

[0084] like Figure 2 As shown, in some embodiments, a vertical scale 500 is fixedly connected to the other side of the vertical side of the support.

[0085] In this embodiment, the scale 500 can be directly attached to the vertical side of the support 400.

[0086] Specifically, on one side of the vertical side of the support 400, a mounting groove may be provided, and on the other side away from that side (which may be the same vertical side or another side), a vertical scale 500 may be provided.

[0087] In some embodiments, the laser emitter receiving unit is a laser emitter fixing slot.

[0088] In some embodiments, the laser emitting unit further includes:

[0089] A rotating angle scale is fixedly connected to the support part 400 and is engraved with scale lines.

[0090] A rotating angle needle, one end of which is fixedly connected to the other end of the angle adjustment mechanism 310, and the other end of which cooperates with the rotating angle scale to indicate the precise emission angle of the laser emitter 320.

[0091] This embodiment significantly improves the adjustment accuracy and ease of operation of the device by adding a rotation angle scale and a rotation angle needle to the laser emitting unit. The rotation angle scale is fixedly connected to the support unit 400, and its scale lines can intuitively display the emission angle of the laser emitter 320, while the rotation angle needle is connected to the angle adjustment mechanism 310 to indicate the precise angular position of the laser emitter 320. This design allows construction personnel to quickly and accurately adjust the laser to the preset target position, reducing errors from manual measurement and improving construction efficiency. At the same time, the combined use of the rotation angle scale and the rotation angle needle further enhances the stability and reliability of the device, providing more precise technical support for the alignment and leveling of the anchor plate.

[0092] In some embodiments, the rotation angle scale is semi-circular, and one side of the vertical edge of the rotation angle scale is fixedly connected to the support portion 400.

[0093] In some embodiments, the level detection unit 200 includes at least two level bubble structures.

[0094] This embodiment significantly improves the leveling accuracy and ease of operation of the device by incorporating at least two leveling bubbles in the leveling detection unit 200. Multiple leveling bubbles can simultaneously detect the levelness of the device from different directions, helping construction personnel quickly determine and adjust the levelness of the anchor plate. This design not only improves detection accuracy but also reduces errors from manual operation, making it suitable for scenarios requiring high-precision leveling adjustments. Furthermore, the leveling bubbles are simple in structure, low in cost, and easy to maintain and replace, providing efficient and reliable technical support for the alignment and leveling of the anchor plate.

[0095] In some embodiments, the level detection unit 200 includes two horizontal bubbles, which are symmetrically arranged along the edge of the upper surface of the base unit 100 with the support unit 400 as the center of symmetry.

[0096] This embodiment significantly improves the accuracy and stability of the device's horizontal detection by setting two horizontal bubble levels in the horizontal detection section 200 and symmetrically arranging them along the edge of the upper surface of the base section 100 with the support section 400 as the center of symmetry. The symmetrically distributed horizontal bubble levels can simultaneously detect the device's horizontal state from two directions, helping construction personnel to quickly and accurately judge and adjust the anchor plate's levelness. This design not only improves the comprehensiveness and reliability of the detection but also reduces errors from manual operation, making it suitable for scenarios requiring high-precision horizontal adjustment. Simultaneously, the symmetrical layout enhances the overall balance of the device, providing more efficient and stable technical support for the alignment and leveling of the anchor plate.

[0097] In some embodiments, the base portion 100 is a magnetic base.

[0098] like Figure 3 As shown, in one specific embodiment, an anchor plate alignment and leveling device is provided, which may include:

[0099] The disc-shaped magnetic base 101 is used to fix the centering and leveling device to the preset installation point of the anchor plate.

[0100] Two horizontal liquid bubbles 201 are fixed above the magnetic base 101 and are configured to indicate the horizontal state of the device.

[0101] The support part 400 is fixedly connected at its bottom to the top surface of the magnetic base 101.

[0102] The rotating rod 311 has one end hinged to the side of the support 400 via a fixing bolt 314, and the other end is provided with a laser emitter fixing groove 312, in which a laser emitter can be installed. A rotation angle needle 313 is also provided at the end with the laser emitter fixing groove 312. To adapt to the rotation angle needle 313 for more precise and accurate control of the laser emitter's rotation angle, a semi-circular angle gauge 315 is also provided on the side of the support.

[0103] The scale 500 can be attached to the side of the support 400.

[0104] Working principle:

[0105] First, the device is attached to the pre-set mounting point on the anchor plate using the disc-shaped magnetic base 101. The magnetic base 101 provides a quick and stable fixation method, ensuring that the device will not slide or shift during construction. Two horizontal bubble levels 201 are symmetrically positioned along the upper edge of the magnetic base 101. After the device is fixed, observe the position of the bubbles in the horizontal bubble levels 201. If the bubbles are centered, the device is level and the next step can be performed. If the bubbles are off-center, the support bolts of the anchor plate need to be adjusted until the bubbles are centered, ensuring the device is level.

[0106] One end of the rotating rod 311 is hinged to the support part 400 via a fixing bolt 314, and the other end is provided with a laser emitter fixing groove 312 and a rotation angle needle 313. Loosening the fixing bolt 314 and manually rotating the rotating rod 311 causes the laser emitter to rotate around the hinge point. A semi-circular angle gauge 315 is fixed to the side of the support part 400 and works in conjunction with the rotation angle needle 313. The rotation angle needle 313 rotates with the rotating rod 311, and its tip points to the scale line of the angle gauge 315, accurately displaying the current rotation angle of the laser emitter.

[0107] According to the angle requirements of the preset target position (such as the angle between the laser beam and the center point of the foundation when the centering and leveling device is installed on the anchor plate as shown in the design drawings), adjust the rotating angle needle 313 to the corresponding scale, and then tighten the fixing bolt 314 to lock the rotating rod 311. The laser emitter is fixed in the laser emitter fixing slot 312 at the end of the rotating rod 311, and the emitted laser beam is pointed to the center point of the foundation. In the installation of large anchor plates (such as lower or upper anchor plates), multiple centering and leveling devices can be distributed on the preset installation points of the anchor plate. The laser beams of all devices must converge on the same target point (such as the center of the foundation). By observing the readings of the angle ruler 315 and the scale ruler 500 of each device, the position of the anchor plate is adjusted synchronously until all laser beams are precisely aligned.

[0108] During the installation of the lower and upper anchor plates, an external horizontal laser can be used for fine-tuning of the levelness. At the construction site, a horizontal laser emitter can be installed at the center of the upper and lower anchor plates (usually hollow ring structures) or at another pre-set location. Adjust the height of the horizontal laser emitter so that its emitted horizontal laser beam illuminates the vertical scale 500 on each alignment and leveling device. After the height of the horizontal laser emitter is adjusted, observe the laser-illuminated values ​​on each vertical scale 500. If the values ​​on all scales 500 are consistent, it indicates that the overall levelness of the upper and lower anchor plates has reached the design accuracy. If the values ​​are inconsistent, fine-tune the support bolts of the lower anchor plate or other adjustment mechanisms to make the values ​​on each scale 500 consistent, thereby achieving high-precision leveling of the lower anchor plate.
