Description

Technical Field

[0001] This utility model relates to the technical field of settlement observation devices, specifically to a wind turbine foundation settlement observation device. Background Technology

[0002] As a tall structure, the wind turbine tower is susceptible to significant horizontal deviations from its structure even with slight uneven foundation settlement. This can trigger eccentric bending moments, causing the turbine to tilt. This not only poses safety hazards but can also induce resonance, disrupt the turbine's dynamic balance, increase vibration, affect the normal operation of the entire system, and even damage the turbine, resulting in substantial economic losses.

[0003] A search revealed CN216432951U, which describes a wind turbine foundation settlement monitoring device. The device includes a settlement monitoring box mounted on the wind turbine foundation structure. A detachable partition divides the settlement monitoring box into upper and lower cavities. A universal level is mounted on the partition within the settlement monitoring box to display the offset information of the wind turbine foundation structure. When installing the settlement monitoring box, it is necessary to fix the wind turbine foundation structure (concrete) before it hardens.

[0004] During the installation of the aforementioned wind turbine foundation settlement monitoring device, the settlement monitoring box is installed on the concrete before it has hardened. As the concrete hardens, it deforms or shifts, requiring the installation of a structure on the settlement monitoring box to prevent it from shifting. After the concrete hardens, the anti-shifting structure on the settlement monitoring box is then disassembled. This process is cumbersome and does not improve the installation efficiency of the settlement monitoring device.

[0005] Based on this, this utility model designs a wind turbine foundation settlement monitoring device to solve the above problems. Utility Model Content

Detailed Implementation

[0025] 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, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] Please refer to the accompanying drawings in the instruction manual. Figures 1-5 A wind turbine foundation settlement observation device includes a first fixed frame 1 and a second fixed frame 2, both of which are arc-shaped structures. The rear ends of the first fixed frame 1 and the second fixed frame 2 are hinged together. The front end of the first fixed frame 1 abuts against the front end of the second fixed frame 2. The wind turbine tower is located between the first fixed frame 1 and the second fixed frame 2. The side walls of the wind turbine tower abut against the side walls of the first fixed frame 1 and the second fixed frame 2 respectively. A rotating block 3 is rotatably installed on the side wall of the second fixed frame 2 near the front end of the second fixed frame 2. A connecting block 4 is fixed on the side wall of the first fixed frame 1 near the front end of the first fixed frame 1. A connecting component 5 is provided on the rotating block 3 to fix the rotating block 3 and the connecting block 4 and to keep the first fixed frame 1 and the second fixed frame 2 abutting against the wind turbine tower. A detection mechanism 6 is provided on the first fixed frame 1 to detect the settlement of the wind turbine tower.

[0029] The connecting component 5 includes a connecting bolt 51 that passes through and is threaded onto the rotating block 3, a limiting block 52 fixed to one end of the connecting bolt 51 near the connecting block 4, and a handle 53 fixed to one end of the connecting bolt 51 away from the connecting block 4. The cross-sectional diameter of the limiting block 52 is larger than that of the connecting bolt 51. A connecting through hole 54 is provided on the top of the connecting block 4 for the connecting bolt 51 to pass through and engage. A limiting through hole 55 communicating with the connecting through hole 54 is provided on the side wall of the connecting block 4 away from the rotating block 3. The limiting block 52 and the limiting through hole 55 are inserted into each other.

[0030] Rotating handle 53 causes connecting bolt 51 and limiting block 52 to rotate. Since connecting bolt 51 is threadedly connected to rotating block 3, both connecting bolt 51 and limiting block 52 move towards connecting block 4 until limiting block 52 separates from limiting through hole 55. At this point, rotating connecting bolt 51 and turning it upwards until connecting bolt 51 separates from connecting through hole 54 allows the first fixing frame 1 and the second fixing frame 2 to be removed from the wind turbine tower. Similarly, the first fixing frame 1 and the second fixing frame 2 are pressed against the wind turbine tower, and then connecting bolt 51 is turned over until it is engaged in connecting through hole 54. Then, rotating handle 53 in the opposite direction causes connecting bolt 51 and limiting block 52 to rotate until limiting block 52 is engaged in limiting through hole 55 and pressed against limiting through hole 55. This completes the installation of the device, eliminating the cumbersome installation operations of existing settlement monitoring devices and improving the installation efficiency of settlement monitoring devices.

[0031] The detection mechanism 6 includes a detection component 61, which includes a mounting shell 611 fixed to the side wall of the first fixing frame 1, a vertical rod 612 that passes through the top of the mounting shell 611 and is rotatably connected to it, a turntable 613 fixedly sleeved on the vertical rod 612, a spherical block 614 fixed to the upper end of the vertical rod 612, and a level 615 movably connected to the spherical block 614. An indicator strip is fixed to the top of the level 615. The detection mechanism 6 also includes an angle adjustment component 62 for adjusting the angle of the level 615 and keeping the level 615 in a stable state, a rotation component 63 for driving the turntable 613 to rotate, and a measuring component 64 for measuring the distance between the level 615 and the ground.

[0032] The angle adjustment assembly 62 includes an internally threaded sleeve 621 rotatably mounted on the top of the turntable 613, an adjusting screw 622 threadedly connected to the internally threaded sleeve 621, and a connecting plate 623 fixed to the upper end of the adjusting screw 622. The upper end of the connecting plate 623 is rotatably connected to the bottom of the level 615.

[0033] The rotating assembly 63 includes a worm gear 631 rotatably mounted inside the mounting housing 611. The worm gear 631 passes through the side wall of the mounting housing 611 and is rotatably connected. The rotating assembly 63 also includes a knob 632 fixed to the end of the worm gear 631 away from the first fixing frame 1 and a worm wheel 633 fixedly sleeved on the vertical rod 612 and meshing with the worm gear 631. The lower end of the vertical rod 612 is rotatably connected to the inner bottom wall of the mounting housing 611.

[0034] The measuring component 64 includes a connecting pipe 641 fixed to the bottom of the level 615 and a sliding connecting plate 642 slidably connected within the connecting pipe 641. Anti-slip pads are fixed to the side walls of the connecting pipe 641 and the sliding connecting plate 642. A mounting through hole 644 is provided through the top of the sliding connecting plate 642. The measuring component 64 also includes a take-up roller 643 rotatably installed within the mounting through hole 644, a rectangular block 645 fixed to one end of the take-up roller 643, and a rotating wheel 646 fixed to the end of the rectangular block 645 away from the take-up roller 643. A measuring tape is wound around the take-up roller 643.

[0035] Observe whether the bubble in the level 615 is located in the center of the level 615. If it is in the center, it indicates that the wind turbine tower has not tilted or settled. If it is not in the center, it indicates that the wind turbine tower has tilted or settled. At this time, observe whether the bubble coincides with or is located on the extension line of the indicator bar. If it coincides with or is located on the extension line of the indicator bar, rotate the internal threaded sleeve 621. Since the internal threaded sleeve 621 is threadedly connected to the adjusting screw 622, and the connecting plate 623 is rotatably connected to the turntable 613, the adjusting screw 622 and the connecting plate 623 move upward or downward. The level 615 is adjusted until the bubble is in the middle of the turntable 613. If the bubble does not coincide with the indicator bar or is not on its extension line, the knob 632 is rotated to drive the worm gear 631 to rotate. This causes the worm wheel 633 meshing with the worm gear 631, the vertical rod 612 fixed to the worm wheel 633, the turntable 613 fixed to the vertical rod 612, the spherical block 614 connected to the vertical rod 612, and the level 615 connected to the spherical block 614 to all rotate until the bubble is on or on the extension line of the indicator bar. At this point, the level 615 can be adjusted to facilitate the use of the device. After the bubble and the center of the level 615 are aligned, the sliding connecting plate 642 is first pulled away from the level 615 until the mounting through hole 644 is located outside the turntable 613. At this time, the rotating wheel 646 can be rotated to drive the rectangular block 645 to rotate. The winding roller 643 rotates and releases the tape measure wound on it, and measures the height of the level 615 from the ground. The height is then compared with the normal height. The difference between the two can be used to measure the settlement value. By leveling the level 615 before measurement, the measurement error is reduced.

[0036] Rubber pads 7 are fixed to the side walls of the first fixing frame 1 and the second fixing frame 2 that are close to each other. The side walls of the wind turbine tower are pressed against the side walls of the two sets of rubber pads 7 that are close to each other. The rubber pads 7 increase the friction between the first fixing frame 1, the second fixing frame 2 and the wind turbine tower.

[0037] The measuring assembly 64 also includes a limiting plate 647 rotatably mounted on the side wall of the sliding connecting plate 642. The lower end of the limiting plate 647 has an insertion groove for engaging with the rectangular block 645. The limiting plate 647 provides a good limiting function when the rectangular block 645 is not in use.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
