In order to prevent the wind turbines at high altitudes from tilting, which in turn threatens the normal operation and safety of the power towers, it is necessary to monitor the inclination of the wind turbine towers for a long time. Once the inclination exceeds the safe value, an early warning can be issued in time, and personnel can be notified to conduct inspections and maintenance, thereby ensuring the stability of daily power generation work.

[0024] Example 3

[0025] The utility model of the wind turbine tower inclination monitoring device has a structure as follows Figure 1 and Figure 2 As shown, it includes a scale plate 1, which is fixed to a tower 2 by a screw rod 3, and the scale plate 1 fits tightly with the tower 2. A central rotating mechanism 4 is movably connected at the center of the scale plate 1, and the central rotating mechanism 4 is fixedly connected to the tower 2, as shown in FIG. Figure 3 As shown, the central rotating mechanism 4 includes a central rotating shaft 41 located at the center thereof, and a ball 42 is arranged on the outer ring of the central rotating shaft 41. A balancing panel 5 is connected to the outer surface of the central rotating mechanism 4. Due to the arrangement of the ball 42, the balancing panel 5 can rotate around the central rotating mechanism 4. A hanging mechanism 6 is arranged directly below the balancing panel 5. The hanging mechanism 6 includes a vertical rod 61, a plumb line 62 and a plumb bob 63 connected in sequence from top to bottom, wherein the vertical rod 61 is fixedly connected to the side of the balancing panel 5. A balancing mechanism 8 is also fixedly connected to the side of the balancing panel 5. The balancing mechanism 8 is arranged vertically to the hanging mechanism 6. The balancing mechanism 8 consists of two parts, which are symmetrical along the central axis of the balancing panel 5. Each part includes a balancing screw 81 connected to the outer side of the balancing panel 5. The balancing screw 81 is threadedly connected with an inner nut 82, a balancing weight 83 and an outer nut 84 in sequence from the inside to the outside. The other end of the balancing screw 81 is fixedly connected to a dial pointer 85. A tube bubble 7 is arranged at the center of the upper part of the balancing panel 5.

[0026] The process of using the monitoring device of the utility model to monitor the inclination is as follows:

[0027] Step 1, fix the monitoring device on the tower 2 through the screw 3;

[0028] Step 2: Adjust the balancing weights 83 in the balancing mechanism 8 on both sides of the balancing panel 5 so that the tube bubble 7 is centered, and then tighten the inner nut 82 and the outer nut 84 to firmly fix the balancing weights 83 on the balancing screw 81. At this time, the balancing mechanism 8 is in a horizontal state, and the hanging mechanism 6 perpendicular to it is in a vertical state. Figure 4 As shown, read the scale indicated by the dial pointer 85 at this time, record it as α1, and use α1 as the initial angle value of the wind turbine tower to be monitored at this time;

[0029] Step 3: Figure 4 As shown, when the inclination of the tower needs to be obtained during the monitoring process, the monitoring device is first calibrated, the balancing weight 83 is adjusted to make the tube bubble 7 centered, and then the reading α2 of the dial pointer 85 is read as the monitoring angle value of the wind turbine tower at this time;

[0030] Step 4: The difference α between the monitoring value α2 and the initial value α1 is the inclination of the wind turbine tower;

[0031] Step 5: Figure 5 As shown, based on monitoring the wind turbine tower height AA′ and the tilt angle α, the wind turbine tower tilt position value AC′=AA′×tanα can be calculated.

[0032] When α2-α1>0, AC ′ The value is "+", indicating that the wind turbine tower is tilted to the left at this time;

[0033] When α2-α1<0, AC ′ The value is "-", indicating that the wind turbine tower is tilted to the right;

[0034] When α2-α1=0, AC ′ A value of 0 indicates that the wind turbine tower is not tilted.

[0035] This embodiment monitors a wind turbine tower of a wind farm. The wind turbine tower is 75 meters high. The monitoring device is placed at a height of 5 meters. The initial angle of the dial reading is 0°, the first monitoring reading is 0°4′, and the second reading is 0°7′. The calculation results are shown in Table 1 below.
