[0002] As the height of wind turbine concrete towers continues to increase, the requirements for tower safety are also becoming more stringent, especially regarding nonlinear deformation of the tower caused by factors such as second-order vibrations. Tower safety has an increasingly significant impact on the overall safety of the turbine unit. Tower deformation during turbine operation corresponds to swaying at the tower top and foundation tilting. Existing monitoring methods typically use single tilt sensors or accelerometers, which, due to limitations in sensor principles and operating conditions, introduce certain errors when measuring tower tilt.

[0003] Current technology CN211696345U discloses a tower monitoring system integrating tilt sensors and gyroscopes, including a tower top sensor group, a foundation sensor group, a data unit, and a main control system. The tower top sensor group and the foundation sensor group are connected to the main control system via the data unit, and the main control system is connected to a terminal. A sensor group is installed on the top wall of the wind turbine tower and at the foundation location, respectively. Each sensor group includes a dual-axis tilt sensor and a dual-axis gyroscope. By measuring the tilt angle of the tower top and the foundation, as well as the angular velocity in the tilt direction, the system improves monitoring accuracy and reduces misjudgments caused by system errors.

[0004] However, using the above method, the dual-axis tilt sensor and dual-axis gyroscope need to be installed at the top of the wind turbine tower to monitor data. When maintenance is required on the dual-axis tilt sensor and dual-axis gyroscope, staff need to climb to the top for maintenance, which causes inconvenience when maintaining the dual-axis tilt sensor and dual-axis gyroscope.

[0021] This utility model provides a monitoring device for wind turbine concrete towers, including a guide plate 101 and a monitoring assembly. The monitoring assembly includes a guide rail 102, a mounting base 103, a rack 104, and two monitoring components 105. Each monitoring component 105 includes a slider 106, a dual-axis tilt sensor 107, a dual-axis gyroscope 108, a drive unit 109, and a gear 110. The drive unit 109 includes a base 111, a motor 112, a reducer 113, a protective cover 114, and two connectors 115. Each connector 115 includes a spring 116, a plug rod 117, and a locking bolt 118. This design allows workers to easily inspect and maintain the dual-axis tilt sensor 107 and the dual-axis gyroscope 108 installed on the top of the wind turbine tower.

[0022] In this specific embodiment, the guide rail 102 and the guide plate 101 are fixedly connected and located on the side of the guide plate 101; the mounting base 103 is fixedly connected to the guide plate 101 and located on the side of the guide plate 101; the rack 104 is fixedly connected to the mounting base 103 and located on the side of the mounting base 103; two monitoring components 105 are respectively disposed on the side of the guide rail 102, and each monitoring component 105 includes a slider 106, a dual-axis tilt sensor 107, a dual-axis gyroscope 108, and a drive... The moving part 109 and the gear 110; the slider 106 and the guide rail 102 are slidably connected and located on the side of the guide rail 102; the dual-axis tilt sensor 107 and the slider 106 are fixedly connected and located on the side of the slider 106; the dual-axis gyroscope 108 and the slider 106 are fixedly connected and located on the side of the slider 106; the driving part 109 is disposed on the side of the slider 106; the gear 110 is disposed on the side of the driving part 109, and the gear 110 meshes with the rack 104. In use, the guide plate 101 is installed on the surface of the wind turbine concrete tower. One of the monitoring components 105 is located at the top of the tower, and the other monitoring component 105 is located at the tower foundation. This results in one dual-axis tilt sensor 107 and one dual-axis gyroscope 108 at the top of the tower and the other at the tower foundation. The dual-axis tilt sensor 107 and the dual-axis gyroscope 108 monitor and obtain the tilt angle and angular velocity in the tilt direction between the tower top and the foundation. Combined with the structural and dimensional characteristics of the foundation, the uneven settlement of the foundation is obtained, improving monitoring accuracy. The specific structure and monitoring principle of the dual-axis tilt sensor 107 and the dual-axis gyroscope 108 are described in patent document CN211696345U, which is not within the scope of this application and will not be elaborated upon here. When it is necessary to monitor the top of the tower... When the dual-axis tilt sensor 107 and the dual-axis gyroscope 108 are being maintained, the drive unit 109 is controlled to drive the gear 110 in reverse. When the gear 110 reverses, it moves downward along the rack 104. The guide rail 102 provides guidance for the slider 106 and the drive unit 109. The slider 106 moves the dual-axis tilt sensor 107 and the dual-axis gyroscope 108 to a lower position, making it easier for staff to maintain the dual-axis tilt sensor 107 and the dual-axis gyroscope 108. After maintenance is completed, the drive unit 109 is controlled to drive the gear 110 to rotate forward, and the slider 106 moves upward along the guide rail 102, allowing the dual-axis tilt sensor 107 and the dual-axis gyroscope 108 to return to the top of the tower. In this way, it is convenient to maintain the dual-axis tilt sensor 107 and the dual-axis gyroscope 108 installed at the top of the wind turbine tower.

[0023] The base 111 is fixedly connected to the slider 106 and is located on the side of the slider 106; the motor 112 is fixedly connected to the base 111 and is located on the side of the base 111; the reducer 113 is fixedly connected to the base 111, the input shaft of the reducer 113 is fixedly connected to the output shaft of the motor 112, and the output shaft of the reducer 113 is fixedly connected to the gear 110 and is located on the side of the base 111. The base 111 supports the motor 112 and the reducer 113. The motor 112 provides power, which drives the gear 110 to rotate via the reducer 113.

[0024] Secondly, the protective cover 114 is located on the side of the base 111; the two connectors 115 are mirror images of each other on both sides of the protective cover 114. The protective cover 114 is used to protect the motor 112 and the reducer 113, preventing damage to the motor 112 and the reducer 113. The connectors 115 can be used to fix the protective cover 114 to the base 111.

[0025] Meanwhile, the spring 116 is fixedly connected to the protective cover 114 and is located inside the protective cover 114; the insert rod 117 is fixedly connected to the spring 116 and is located on the side of the spring 116. The base 111 has a through hole adapted to the insertion rod 117. When installing the protective cover 114, first press the insertion rod 117 to compress the spring 116, then place the protective cover 114 on the base 111, and then release the insertion rod 117. Under the push of the spring 116, the insertion rod 117 is inserted into the base 111, thereby fixing the protective cover 114 to the base 111. When it is necessary to remove the protective cover 114, push the insertion rod 117 away from the base 111 to release the fixation of the protective cover 114, and then the protective cover 114 can be removed. This fixing method facilitates the installation and removal of the protective cover 114, so as to facilitate the maintenance of the motor 112 and the reducer 113.

[0026] Furthermore, the locking bolt 118 is threadedly connected to the protective cover 114 and is located on the side of the protective cover 114. Rotating the locking bolt 118 causes it to abut against the insertion rod 117, which fixes the position of the insertion rod 117 and prevents it from detaching from the base 111, thereby improving the connection stability between the base 111 and the protective cover 114.

[0027] In using this invention, the guide plate 101 is installed on the surface of the wind turbine concrete tower. One monitoring component 105 is located at the top of the tower, and the other monitoring component 105 is located at the tower foundation. This results in one dual-axis tilt sensor 107 and one dual-axis gyroscope 108 being located at the top of the tower and at the tower foundation. The dual-axis tilt sensor 107 and the dual-axis gyroscope 108 monitor and obtain the tilt angle between the tower top and the foundation, as well as the angular velocity in the tilt direction. When maintenance is required on the dual-axis tilt sensor 107 and the dual-axis gyroscope 108 at the top of the tower, the motor 112 drives the gear 110 to reverse. When the gear 110 reverses, it moves downward along the rack 104. The guide rail 102 provides guidance for the slider 106 and the drive unit 109. The slider 106 drives the dual-axis tilt sensor 107 and the dual-axis gyroscope 108 to a lower position, which facilitates the maintenance of the dual-axis tilt sensor 107 and the dual-axis gyroscope 108 by the staff. After the maintenance is completed, the motor 112 is controlled to drive the gear 110 to rotate forward, and the slider 106 moves upward along the guide rail 102, so that the dual-axis tilt sensor 107 and the dual-axis gyroscope 108 return to the top of the tower. In this way, it is convenient to maintain the dual-axis tilt sensor 107 and the dual-axis gyroscope 108 installed at the top of the wind turbine tower.
