Description

Technical Field

[0001] This utility model belongs to the technical field of wind power facility construction, and specifically relates to a quick leveling device for wind turbine foundation anchor plates. Background Technology

[0002] my country possesses abundant onshore wind energy resources, especially in the "Three Norths" region (Northeast, North, and Northwest China). Wind energy, as a crucial component of clean energy, requires vigorous development. The installation of onshore wind turbines begins with the completion of foundation construction. The foundation consists of an anchor cage and structural steel reinforcement. The anchor cage, assembled from upper and lower anchor plates and multiple anchor bolts penetrating these plates, is a key component connecting the wind turbine tower to the foundation, effectively transferring the load from the components above the foundation to the concrete foundation.

[0003] During the installation of the foundation anchor plates, the upper and lower anchor plates need to be pre-assembled to form a preliminary cage shape. Then, the remaining anchor bolts are installed in sequence. After all the anchor bolts are installed, the anchor plates are coarsely adjusted. Since the anchor plates are made of two thick special steel pieces, the coarse adjustment and subsequent fine adjustment require the assistance of surveyors. During the adjustment process, it is necessary to constantly communicate with the surveyors to ensure that the installation elevation is appropriate and meets the accuracy requirements, which greatly consumes manpower and material resources and results in low work efficiency. Utility Model Content

[0004] This invention provides a rapid leveling device for wind turbine foundation anchor plates to solve the problem of low leveling efficiency during wind turbine foundation anchor plate installation.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A rapid leveling device for a wind turbine foundation anchor plate includes a water replenishment piston and multiple leveling cylinders. The multiple leveling cylinders are evenly arranged on the foundation anchor plate, and each leveling cylinder is filled with liquid that is flush with the opening of the leveling cylinder.

[0007] The bottom of the water replenishment piston is connected to a first main pipe, a first valve is installed on the first main pipe, and a first connecting pipe is installed between each leveling cylinder and the first main pipe, and multiple first connecting pipes are interconnected.

[0008] Furthermore, the leveling cylinder includes an outer water storage cylinder and an inner water storage cylinder, the inner water storage cylinder is disposed inside the outer water storage cylinder, and the outer diameter of the inner water storage cylinder is smaller than the inner diameter of the outer water storage cylinder;

[0009] The bottom wall of the inner water storage cylinder is provided with an inner cylinder connector. The inner cylinder connector extends out after passing through the outer water storage cylinder in a sealed manner, and the first connecting pipe is connected to the inner cylinder connector.

[0010] Furthermore, an outer cylinder pipe is connected near the bottom wall of the water storage outer cylinder, and a second connecting pipe is provided between any one of the outer cylinder pipes and the water replenishment piston.

[0011] Furthermore, the leveling cylinder also includes a magnetic base, which is fixed to the bottom of the water storage outer cylinder and is used to adhere to the foundation anchor plate.

[0012] Furthermore, the side wall of the water replenishment piston is also connected to a vent pipe, which is located near the top of the water replenishment piston, and a second valve is provided on the vent pipe.

[0013] Furthermore, the side wall of the water replenishment piston is also connected to a second main pipe, which is located near the bottom of the vent pipe and is equipped with a third valve.

[0014] The end of any of the second connecting pipes furthest from the outer water storage cylinder is connected to the second main pipe.

[0015] Furthermore, the top of the inner water storage cylinder extends from the top of the outer water storage cylinder.

[0016] Furthermore, both the outer and inner water storage cylinders are made of transparent material.

[0017] The present invention can achieve the following beneficial effects:

[0018] 1. This application provides multiple leveling cylinders evenly arranged on the foundation anchor plate, and the leveling cylinders are connected by a first connecting pipe. When the liquid in each leveling cylinder is flush with the opening of the leveling cylinder, it means that the foundation anchor plate has been leveled, thus making the leveling of the foundation anchor plate more convenient and intuitive. If the liquid in the leveling cylinder overflows, it can be replenished by using a water replenishment piston.

[0019] 2. The outer water storage cylinder is designed to collect the liquid overflowing from the inner water storage cylinder. The collected overflow water flows into the water replenishment piston and then replenishes the inner water storage cylinder, forming a circulating water flow path and enabling the entire leveling device to operate in a cyclical manner.

[0020] 3. The magnetic base allows the leveling cylinder of this application to be installed and disassembled on the foundation anchor plate more quickly and conveniently, and the leveling cylinder tilts synchronously with the foundation anchor plate, resulting in more accurate measurement.

[0027] 100. Foundation anchor plate. Detailed Implementation

[0028] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0029] like Figures 1 to 3 As shown, a wind turbine foundation anchor plate quick leveling device includes multiple leveling cylinders 2 evenly arranged on the foundation anchor plate 100. The leveling cylinder 2 includes a water storage outer cylinder 21 and a magnetic base 23. The magnetic base 23 is fixed to the bottom of the water storage outer cylinder 21. By setting the magnetic base 23, the leveling cylinder 2 can be quickly installed and fixed on the foundation anchor plate 100, and the installation and disassembly are convenient and quick.

[0030] The leveling cylinder 2 also includes a water storage inner cylinder 22, which is disposed inside the water storage outer cylinder 21. The outer diameter of the water storage inner cylinder 22 is smaller than the inner diameter of the water storage outer cylinder 21, and the top of the water storage inner cylinder 22 extends out from the top of the water storage outer cylinder 21. An inner cylinder connector 221 is provided near the bottom of the water storage inner cylinder 22. The inner cylinder connector 221 extends out after passing through the water storage outer cylinder 21, and the point where the inner cylinder connector 221 passes through the water storage outer cylinder 21 is sealed. An outer cylinder connector 211 is provided near the bottom of the water storage outer cylinder 21.

[0031] The leveling device of this application is also equipped with a water replenishment piston 1. The water replenishment piston 1 is connected to a first main pipe 11, a second main pipe 13, and a vent pipe 12. A first valve 111 is installed on the first main pipe 11, a second valve 121 is installed on the vent pipe 12, and a third valve 131 is installed on the second main pipe 13. Each inner cylinder pipe 221 is connected to the first main pipe 11 by a first connecting pipe 4, and each outer cylinder pipe 211 is connected to the second main pipe 13 by a second connecting pipe 5. Thus, the water replenishment piston 1 and the first connecting pipe 4 can achieve internal communication between multiple water storage inner cylinders 22, and the water replenishment piston 1 and the second connecting pipe 5 can achieve internal communication between multiple water storage outer cylinders 21.

[0032] In a preferred embodiment, during the leveling of the foundation anchor plate 100, three leveling cylinders 2 are provided on the foundation anchor plate 100. After all three leveling cylinders 2 are at the same height, the plane on which the foundation anchor plate 100 is located is leveled. The three leveling cylinders 2 are A leveling cylinder 2, B leveling cylinder 2, and C leveling cylinder 2. When using the leveling device of this application to level the foundation anchor plate 100, the installation surveyor first determines the final elevation that the foundation anchor plate 100 needs to be installed at, then marks the control points, adjusts a certain point of the foundation anchor plate 100 to the final elevation, and then fixes A leveling cylinder 2 at that point to form a reference standard with A leveling cylinder 2 as the reference point. B leveling cylinder 2 and C leveling cylinder 2 are fixed at other positions on the foundation anchor plate 100, respectively.

[0033] Pour colored water into the inner water storage cylinder 22, ensuring that there are no air bubbles remaining in the connecting water pipe. After filling, close all valve switches on the water replenishment piston 1. It should be noted that both the outer water storage cylinder 21 and the inner water storage cylinder 22 are made of transparent material, which facilitates leveling and observation by the operator.

[0034] After determining the baseline elevation of leveling cylinder A 2, the elevation of the foundation anchor plate 100 is adjusted by adjusting the other two leveling cylinders 2. If the position of leveling cylinder B 2 is higher, the water in the inner water storage cylinder 22 will be lower than the opening of the inner water storage cylinder 22, and liquid will overflow from the other inner water storage cylinders 22. At this time, the foundation anchor plate 100 in the area of ​​leveling cylinder B 2 needs to be adjusted downwards. If the position of leveling cylinder C 2 is lower, water will overflow from the inner water storage cylinder 22. At this time, the height of the foundation anchor plate 100 at leveling cylinder C 2 needs to be raised.

[0035] Water overflowing during the adjustment process is collected in the outer water storage cylinder 21 and then returned to the water replenishment piston 1 via the second connecting pipe 5 and the second main pipe 13. The water replenishment piston 1 simultaneously replenishes water into the inner water storage cylinder 22 via the first main pipe 11. Therefore, the first main pipe 11 is located at the bottom of the water replenishment piston 1, the second main pipe 13 is located at the top of the water replenishment piston 1, and the vent 12 is located on the side wall of the water replenishment piston 1 near the top, so that the inside of the water replenishment piston 1 is connected to the outside, maintaining the air pressure balance inside the water replenishment piston 1.

[0036] The total liquid volume in the entire leveling device should be the total liquid volume when the three inner water storage cylinders 22 are filled and the first connecting pipe 4 and the first main pipe 11 are filled with liquid. When the three leveling cylinders 2 are all at the same height, the three leveling cylinders 2 are all filled with liquid and do not overflow.

[0037] This leveling device allows workers to determine whether the foundation anchor plate 100 is level simply by observing whether liquid seeps out of or fills the inner water storage cylinder 22. Furthermore, this leveling device requires multiple operators, each responsible for leveling one leveling cylinder 2, enabling simultaneous leveling of multiple cylinders 2. Using this leveling device reduces repeated communication between installers and surveyors during the leveling process, freeing up surveyors' time, improving work efficiency, and saving time spent installing the foundation anchor plate 100.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
