Description

Technical Field

[0001] This utility model relates to the field of wind turbine tilt detection technology, specifically a wind turbine tilt detection device. Background Technology

[0002] The working principle of a wind turbine is relatively simple. It converts wind energy into mechanical energy through a wind turbine shaft and blades, and then converts the mechanical energy into electrical energy through a generator driven by the wind turbine shaft. Wind turbines are generally installed high in the air by a column, so the stability of the wind turbine is particularly important. It is necessary for staff to check its stability regularly and whether it is tilted.

[0003] Patent application number 202220888073.9 proposes a tilt detection device for wind turbines. By monitoring the extension and retraction of multiple contact telescopic rods, the device can determine the degree of offset of the wind turbine base. Through the cooperation of multiple electric telescopic support rods and multiple electronic levels, the device avoids deviations in the soil around the wind turbine base caused by wind turbine settlement, ensuring the reliability of the monitoring data from multiple contact telescopic rods and making the monitoring of the wind turbine more accurate.

[0004] However, the device has some shortcomings in use. For example, it can only detect one height plane of the wind turbine main column and only detects the direction of contact between a few contact telescopic rods and the main column, resulting in limited detection data and difficulty in accurately detecting the specific condition of the wind turbine main column, which is difficult to meet people's needs. Utility Model Content

[0014] Compared with the prior art, the present invention provides a wind turbine tilt detection device, which has the following advantages:

[0015] 1. This wind turbine tilt detection device is installed at the bottom of the wind turbine, with a tilt detection ring fitted onto the main column of the wind turbine. The tilt detection rod is positioned by a roller at one end, which abuts against the surface of the main column to detect the tilt of the main column.

[0022] Please see Figure 1-4 A wind turbine tilt detection device includes two tilt detection rings 2, with protective cylinders 1 on the outer surfaces of the two tilt detection rings 2. Multiple multi-stage electric push rods 3 are installed between the two tilt detection rings 2 to adjust the position of the upper tilt detection ring 2, facilitating the detection of the tilt angle of the wind turbine at different heights and improving the device's accuracy. A processor 4 is fixedly installed on the upper surface of the lower tilt detection ring 2, and multiple support legs 6 are fixedly installed on the bottom surface of the tilt detection ring 2. Support plates 7 are fixedly installed at the bottom ends of the support legs 6, and positioning rods 8 are inserted through each support plate 7. During device installation, the support plates 7 abut against the ground, and the positioning rods 8 on the support plates 7 are inserted deep into the ground to facilitate overall support and fixation of the device. A level 5 is fixedly installed on the outer surface of the protective cylinder 1, which can be used to detect whether the device is tilted. When the device tilts, padding material can be added to the bottom surface of the corresponding support plate 7 to ensure the device is level and to guarantee its normal operation.

[0023] The lower tilt detection ring 2 is fixedly connected to the protective cylinder 1, and the upper tilt detection ring 2 is slidably connected to the protective cylinder 1. When it is necessary to adjust the distance between the two tilt detection rings 2, the distance can be precisely adjusted by activating the extension and retraction of the multi-stage electric push rod 3. This facilitates the adjustment of the position of the upper tilt detection ring 2, making it convenient to detect the tilt angle of the wind turbine at different heights and improve the accuracy of the device.

[0024] The tilt detection ring 2 includes a ring body 21, with an inner ring 22 rotatably mounted inside the ring body 21. Multiple tilt detection rods 9 are fixedly mounted on the inner surface of the inner ring 22, and a gear ring 23 is fixedly mounted on the outer surface of the inner ring 22. A working cavity is formed between the inner ring 22 and the ring body 21, and a motor 24 is fixedly mounted inside the working cavity. A gear 25 is fixedly mounted on the outer surface of the output shaft of the motor 24, meshing with the gear ring 23. A roller 96 at one end of each tilt detection rod abuts against the surface of the main column to detect the tilt of the main column. Starting the motor 24 drives the gear 25 to rotate, causing the inner ring 22 meshing with the gear ring 23 to rotate accordingly. The rotation of the inner ring 22 drives the tilt detection rods 9 to perform omnidirectional angle detection, ensuring that the device can comprehensively and accurately detect the tilt.

[0025] See Figure 4 The tilt detection rod 9 includes a sleeve 91 with one end fixed to the inner ring 22. An insert rod 92 is inserted inside the sleeve 91. One end of the insert rod 92 extends to the outside of the sleeve 91 and is fixedly mounted with a roller 96. A displacement sensor 93 is fixedly mounted inside the sleeve 91. The detection end of the displacement sensor 93 abuts against the surface of the other end of the insert rod 92. A push plate 94 is fixedly mounted on the outer surface of the insert rod 92. The push plate 94 is slidably disposed inside the sleeve 91. A spring 95 is sleeved on the outer surface of the displacement sensor 93. One end of the spring 95 is connected to the inner wall of the sleeve 91, and the other end of the spring 95 is connected to the surface of the push plate 94.

[0026] When the wind turbine tilts, it presses against the roller 96, pushing the insertion rod 92 to slide within the sleeve 91. The sliding of the insertion rod 92 causes the push plate 94 to move, which in turn compresses or stretches the spring 95, while simultaneously changing the detection value of the displacement sensor 93.

[0027] Furthermore, the processor 4 is equipped with a storage chip and a battery. The processor 4 is also equipped with a wireless connection module for connecting to external devices. The wireless connection module adopts a 4G / 5G wireless connection module. The processor 4 is electrically connected to the multi-stage electric push rod 3, the motor 24 and the displacement sensor 93. The displacement sensor 93 transmits the detected displacement value to the processor 4. The processor 4 converts the displacement value into tilt, processes and stores the data, and transmits the tilt data to the external device in real time through the built-in 4G / 5G wireless connection module.

[0028] Working Principle: This wind turbine tilt detection device is installed at the bottom of the wind turbine, with a tilt detection ring fitted onto the main column of the wind turbine. A roller 96 at one end of the tilt detection rod 9 abuts against the surface of the main column to detect its tilt. When the wind turbine tilts, it presses against the roller 96, pushing the insertion rod 92 to slide within the sleeve 91. The sliding of the insertion rod 92 moves the push plate 94, which in turn compresses or stretches the spring 95, simultaneously changing the detection value of the displacement sensor 93. The displacement sensor 93 transmits the detected displacement value to the processor 4, which converts the displacement value into tilt angle, processes and stores the data, and transmits the tilt data to external devices in real time via a built-in 4G / 5G wireless connection module. When it is necessary to adjust the distance between the two tilt detection rings 2, precise adjustment of the distance can be achieved by controlling the extension and retraction of the multi-stage electric push rod 3. Starting the motor 24 drives the gear 25 to rotate, causing the inner ring 22, which meshes with the gear ring 23, to rotate accordingly. The rotation of the inner ring 22 drives the tilt detection rod 9 to perform all-round angle detection, ensuring that the device can detect the tilt comprehensively and accurately.
