DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0022] See also Figure 1-4 The present embodiment provides a technical solution: a tilt settlement monitor for a wind turbine, comprising a tower 1 and a supporting pier 8, a tower pier 3 is installed at the lower end of the tower 1, a supporting platform 7 is arranged on the upper side of the supporting pier 8 and the upper side of the tower pier 3, an anti-slip column 11 is arranged on the lower side of the supporting platform 7, a fixing plate 14 is installed on the upper side of the supporting platform 7, a threaded rod 10 is circumferentially installed on the lower side of the fixing plate 14, a ball joint structure 13 is arranged on the upper end of the threaded rod 10, a clamping nut 12 is installed on the threaded rod 10, a horizontal adjustment nut 9 is arranged on the lower side of the clamping nut 12, an observation point dynamic level 5 is installed on the upper side of the fixing plate 14, a reference point dynamic level 6 is installed on the fixing plate 14 on the supporting pier 8, and dynamic inclination sensors 2 are installed on the outer sides of the upper and lower ends of the tower 1.

[0023] like Figure 1-4As shown, the dynamic inclination sensor 2 can accurately measure the inclination angles of the upper and lower ends of the tower 1, and the observation point dynamic level 5 and the reference point dynamic level 6 can accurately measure the change in water pressure, and then calculate the change in water pressure through the back-end data statistics equipment, and then calculate the settlement of the tower 1 at each circumferential position. When installing the observation point dynamic level 5 and the reference point dynamic level 6, the height of the fixed plate 14 can be adjusted by rotating the horizontal adjustment nut 9. After the height is adjusted, the clamping nut 12 is rotated downward so that the clamping nut 12 is clamped with the horizontal adjustment nut 9, thereby ensuring the height of the fixed plate 14 and ensuring that the installation heights of the observation point dynamic level 5 and the reference point dynamic level 6 are the same, thereby ensuring monitoring accuracy.

[0024] It also includes a first pipeline 16 and a cable 17 , through which the observation point dynamic level 5 and the reference point dynamic level 6 are connected.

[0025] The observation point dynamic level 5 and the reference point dynamic level 6 are both connected to the corresponding fixing plates 14 via bolts.

[0026] like Figure 1-2 As shown, the liquid storage tank 4 is filled with silicone oil, so that the silicone oil can flow along the pipeline to the inside of the observation point dynamic level 5 and the reference point dynamic level 6, and a communicating vessel is formed between the observation point dynamic level 5 and the reference point dynamic level 6 connected by the pipeline. When the position of the observation point dynamic level 5 sinks or rises, the pressure of the silicone oil inside changes, and the data monitoring module at the back end can monitor the pressure change and calculate the settlement value through the calculation module.

[0027] The dynamic inclination sensor 2 is connected to the tower 1 through the installed mounting frame, a liquid storage tank 4 is installed on one side of the reference point dynamic level 6, the lower end of the horizontal adjustment nut 9 is rotatably connected to the support platform 7, the clamping nut 12 and the horizontal adjustment nut 9 are both threadedly connected to the threaded rod 10, and also includes a second pipe 15, the liquid storage tank 4 is connected to the reference point dynamic level 6 through the second pipe, and the anti-detachment column 11 and the support platform 7 are an integrally formed structure.

[0028] like Figure 1-3 As shown, the anti-slip column 11 allows the support platform 7 to be inserted into the inner side of the tower pier 3, so that the tower pier 3 can be fixed on the tower pier 3 when the concrete is poured.

[0029] The observation point dynamic level 5 is arranged in a ring shape around the tower 1 , and the observation point dynamic level 5 is arranged in a regular hexagon on the outer ring side of the bottom of the tower 1 .

[0030] The working principle of the tilt settlement monitor of a wind turbine provided by the utility model is as follows: Figure 1-Figure 4As shown, when in use, the dynamic inclination sensor 2 can accurately measure the inclination angles of the upper and lower ends of the tower 1, and the observation point dynamic level 5 and the reference point dynamic level 6 can accurately measure the change in water pressure, and then calculate the change in water pressure through the data statistics equipment at the back end, and then calculate the settlement amount of the tower 1 at each circumferential position. When installing the observation point dynamic level 5 and the reference point dynamic level 6, the height of the fixed plate 14 can be adjusted by rotating the horizontal adjustment nut 9. After the height is adjusted, the clamping nut 12 is rotated downward so that the clamping nut 12 is clamped with the horizontal adjustment nut 9, thereby ensuring the height of the fixed plate 14 and ensuring that the installation heights of the observation point dynamic level 5 and the reference point dynamic level 6 are the same, thereby ensuring monitoring accuracy.
