In the breakwater wind power construction, when the upper and lower anchor plates of the wind power pile cap foundation structure are installed, the design specification strictly requires the construction measurement accuracy.

[0003] At present, in the installation and construction process of the wind power anchor plate, the flatness observation of the upper anchor plate and the lower anchor plate adopts the combination of the level and the personnel holding the scale; because the setting position of the anchor plate is high, the personnel generally need to stand in the basket of the crane, and then the scale is erected on the anchor plate, and then the measurement is carried out through the level. However, according to the past construction experience, under the influence of the strong wind on the sea, when the upper and lower anchor plates are installed, the traditional measuring scale is easily affected by the wind and shakes unstably under the human single-arm holding, which affects the flatness precision observation of the anchor plate and cannot guarantee the absolute balance of the measuring scale; and because the measurement time is long, the personnel holding the scale are easy to produce body fatigue, which also causes the scale to shake, and the action of adjusting the scale many times also reduces the work efficiency and affects the construction progress; finally, the flatness measurement of the wind power upper and lower anchor plates not only has a long installation period, but also has a large error in the installation precision. In addition, considering that the construction site is generally in the near-shore tidal water area, which is greatly affected by the wind and the tide, and the holding operation process of the personnel on the upper anchor plate is high-altitude operation, which has uncertain safety risks. Therefore, based on the above technical defects of the prior art, the current urgent need is to design a calibration device that can assist the measurement personnel to quickly hold the scale and improve the successive observation success rate.

[0022] The present application will be further described below in combination with the drawings and specific embodiments, but the following embodiments are by no means any limitation on the present application.

[0023] Reference Figure 1The millimeter-level measuring scale for the rapid installation of wind turbine anchor plates consists of a scale 1, a fixing frame 2, a support frame 3, and a magnetic suction device 4.

[0024] See Figure 2 The scale 1 is a triangular prism with three facets. The scale 1 has three facets, and the scale lines on each facet correspond one-to-one. The scale accuracy is 1mm, so that the high-precision observation needs of multiple directions can be met without rotating the scale 1 during use.

[0025] In this embodiment, the ruler 1 is formed by three measuring rods connected and fixed together along their long edges, with both ends closed. Based on the current construction project's measurement requirements, the ruler 1 is 1500mm long, each surface is 50mm wide, and the smallest graduation is 1mm. In terms of material selection, the ruler 1 is made of high-strength, lightweight aluminum alloy, ensuring it is not easily deformed during operation in complex construction environments and is easy to carry and operate. The graduation lines on the measuring rod are preferably obtained using advanced laser etching technology to ensure a graduation accuracy of ±0.1mm. The zero mark on each measuring rod is flush with the bottom end of the ruler 1, making it flush with the anchor plate surface during use, thus satisfying both anchor plate level and elevation measurements.

[0026] See Figure 3 The fixing frame 2 includes a horizontally arranged triangular frame 201, the inner diameter of which is larger than the outer diameter of the scale 1, so that the scale 1 can be vertically inserted into the frame 201. Horizontal screw holes are respectively opened in the center of the three rods constituting the triangular frame 201, and a fastening bolt 202 is threaded through and connected from the outside to the inside of each horizontal screw hole. In practical application, by adjusting the screw depth of each fastening bolt 202 on the frame 201, the bottom ends of the three fastening bolts 202 are respectively perpendicularly abutted against the three scale surfaces of the scale 1, and the scale 1 is fixed to the frame 201 in a vertical setting.

[0027] In this embodiment, based on the ruler 1 having a width of 50mm in each direction, the frame 201 is composed of three steel rods with a length of 65mm, a width of 10mm, and a longitudinal height of 20mm, which are connected end to end and welded together. The three fastening bolts 202 are bolts with a length of 25mm and a diameter of 5mm.

[0028] As a preferred technical solution of this embodiment, a rubber pad is fixed at the bottom of each fastening bolt 202 so that each fastening bolt 202 contacts the scale surface of the scale 1 through the rubber pad, so as to avoid damaging the scale surface of the scale 1; specifically, the thickness of the rubber pad is set to 2mm.

[0029] A connecting plate 203 is horizontally welded and fixed on the bottom surface of one of the rods of the frame 201. The two ends of the connecting plate 203 extend to the outside of the frame 201 at equal lengths. First connecting holes 204 are symmetrically opened on the two end plates of the connecting plate 203. Each first connecting hole 204 is provided with a first fixing bolt 205 and a matching locking nut.

[0030] As a preferred technical solution in this embodiment, since the scale 1 should be set vertically during use, a horizontal bubble 5 is also provided on either side of the scale surface to facilitate calibration of the scale 1's setting state before each measurement. In this embodiment, the horizontal bubble 5 is a cylindrical horizontal bubble with a diameter of 20mm and a height of 20mm, and its level bubble accuracy is ±0.5mm / m.

[0031] See Figure 4 and Figure 5 The support frame 3 includes two legs, and each leg is hinged to a movable beam 303 at its top, so that each of the two legs is hinged to both ends of the connecting plate 203 of the fixed frame 2 through a movable beam 303.

[0032] Specifically, the movable beam 303 is a strip-shaped beam with a second connecting hole at one end along the longitudinal direction. One end of the movable beam 303 is connected to the end of the corresponding side connecting plate 203 through a first fixing bolt 205 passing through the second connecting hole and the first connecting hole 204. A locking nut matching the first fixing bolt 205 is threaded to the end of the first fixing bolt 205. The other end of the beam has a through groove running horizontally from the end face, and symmetrically through third connecting holes are opened on both sides of the groove wall. Correspondingly, the top of the support leg is a cubic block adapted to the size of the through groove, and a first horizontal through hole is opened on it. The top of the support leg is inserted into the through groove and is hinged to the movable beam 303 through a second fixing bolt 304 passing through the first horizontal through hole and the two third connecting holes. A locking nut matching the second fixing bolt 304 is threaded to the end of the second fixing bolt 304.

[0033] See Figure 1 As a preferred technical solution in this embodiment, the outrigger is a telescopic outrigger; the telescopic outrigger can be a commercially available telescopic rod, such as, but not limited to, a damping telescopic rod; the telescopic outrigger can also be a self-made telescopic outrigger.

[0034] In some embodiments, the outrigger is specifically composed of an outer rod 301 and an inner rod 302. The outer rod 301 is a cylindrical long rod with an axial blind hole on its upper side, and the wall of the blind hole is provided with a connecting internal thread. The inner rod 302 is a cylindrical short rod with a length adapted to the length of the axial blind hole, and the outer wall of the rod is provided with a connecting external thread, so that the inner rod 302 is inserted into the axial blind hole of the outer rod 301 by means of threaded connection. The length of the inner rod 302 extending beyond the outer end of the outer rod 301 is adjustable, that is, the length of the outrigger is adjusted. The top end of the inner rod 302 is set as a cubic block adapted to the size of the through groove, and a horizontal through hole is provided for connection with the movable beam 303.

[0035] In this embodiment, the outer rod 301 of the support leg is 900mm long and 20mm in diameter, while the inner rod 302 is 600mm long and has an adjustable extension length of 400mm relative to the outer rod 301. In practical applications, by adjusting the height of the two support legs, the setting height of the scale 1 on the anchor plate is adapted to the detection range of the level.

[0036] There are two magnetic suction devices 4, which are respectively set at the bottom of the two support legs. This allows the two support legs to be quickly attracted and fixed to the designated measurement position on the anchor plate through the magnetic suction devices 4. This ensures that the two support legs and the scale 1 together form a three-point support structure to maintain structural stability, thereby reducing the impact of wind on the swaying of the scale 1 and achieving the goal of successful observation in one attempt.

[0037] See Figure 6 The magnetic attraction device 4 includes a cubic magnetic block 401 with a centrally located mounting groove on its top surface; the universal hinge 402 uses a ball joint bearing, with its base fixed in the mounting groove and its top side inserted into an axial insertion hole on the bottom surface of the outer rod 301 of the support leg, so that the support leg and the magnetic block 401 are hinged together, and the support leg can rotate relative to the magnetic block 401 in any circumferential direction.

[0038] See Figure 7 The following is a detailed explanation of the usage and measurement principle of the millimeter-level measuring scale used for quick installation of wind turbine anchor plates, using a specific engineering construction project as an example. In this project, the anchor plates of the pier structure include an upper anchor plate and a lower anchor plate, with multiple support rods arranged circumferentially between them. The upper and lower anchor plates are prefabricated from high-strength steel plates and then transported to the construction site for installation. Both the upper and lower anchor plates are circular ring plates with an outer diameter of 5.12m and an inner hollow circle diameter of 4.18m. The working surface width is 0.47m, and the height difference is designed to be 4.41m. The upper anchor plate has a thickness of 0.05m, and the lower anchor plate has a thickness of 0.065m. A ring of pre-drilled holes corresponding to multiple support rods, along with a ring of adjustable anchor plate installation height bolts, is provided circumferentially in the middle of the working surface of the upper and lower anchor plates.

[0039] During construction, the millimeter-level measuring scale for the rapid installation of wind turbine anchor plates was used to observe the flatness of the lower and upper anchor plates after they were installed sequentially. The following description uses the flatness observation of the upper anchor plate 6 as an example to illustrate the specific usage method of the millimeter-level measuring scale for the rapid installation of wind turbine anchor plates.

[0040] See Figure 7 According to the flatness measurement design, eight observation points are set at equal intervals along the circumference on the working surface of the upper anchor plate 6. The millimeter-level measuring scale of the wind turbine anchor plate is set sequentially at the above eight observation points, and the level 7 set on the measuring platform 8 at the construction site is used to read the scale 1 at each observation point in turn. The flatness condition of the upper anchor plate 6 is determined by comparing the difference between the scale readings of the scale 1.

[0041] When measuring the first observation point, the two legs of the support frame 3 are first fixed to the upper anchor plate 6 by the magnetic suction device 4 at the bottom, with the scale 1 corresponding to the observation point. Then, the hinge angle between the movable beam 303 and the legs and the connection and fixing state of the scale 1 on the fixed frame 2 are adjusted so that the bottom end of the scale 1 abuts against the surface of the upper anchor plate 6. The scale 1 is kept absolutely vertical by observing the bubble level 5. At this time, the two legs and the scale 1 form a stable state of three-point support. The scale of the scale 1 is read by the level instrument 7 on the construction site measuring platform 8.

[0042] The observation points are measured sequentially using the method described above. During the measurement process, if the difference between the reading of the scale 1 at the current measurement point (e.g., 100.1 cm) and the reading at a previously measured point (e.g., 100.3 cm) exceeds the required horizontal error range (e.g., ≤1 mm), it indicates that the flatness of the upper anchor plate 6 needs adjustment. At this point, the construction personnel can adjust the installation of the upper anchor plate 6 based on the point-by-point measurement results from the surveyors, or they can adjust it after all eight measurement points have been measured, ultimately ensuring that the flatness of the entire anchor plate meets the design requirements.

[0043] During the actual construction process, the flatness of the upper and lower anchor plates met the millimeter-level requirements of the design. This effectively improved the installation accuracy of the anchor plates, thereby reducing the later maintenance costs of the wind turbines and extending their service life. Furthermore, the improved construction efficiency and shortened construction period brought additional benefits to the project. It is estimated that by improving quality control, the wind farm project can increase its revenue by 5% to 10%. In the long term, the widespread application of this measuring scale will improve the overall quality of the wind power projects undertaken by the company, resulting in significant economic and social benefits.

[0044] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on the structure of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
