Description

A tower vibration monitoring device for wind turbines

Technical Field

The utility model relates to the field of wind turbine generator sets, in particular to a tower vibration monitoring device for wind turbine generator sets.

Background Art

Wind power generation refers to the conversion of wind kinetic energy into electrical energy. It is a clean, pollution-free, renewable energy source. The device required for wind power generation is called a wind turbine. A wind turbine can be roughly divided into three parts: a wind rotor (including a tail rudder), a generator, and a tower. The tower is generally composed of an iron tower, which is a frame that supports the wind rotor, the tail rudder, and the generator. It is generally built relatively high in order to obtain a larger and more uniform wind force, and it must have sufficient strength. In order to avoid damage caused by severe vibration of the iron tower, it is necessary to monitor the vibration of the tower. However, the existing tower vibration monitoring devices are all installed at high places. When the vibration monitoring device is damaged, the staff needs to climb to the height of the tower to replace it, which is not very convenient.

The utility model provides a tower vibration monitoring device for a wind turbine set.

As shown in FIGS. 1-2 , the tower vibration monitoring equipment of the wind turbine provided by the embodiment of the utility model includes a tower body 10 and a tower support 20. The tower support 20 is connected to the outside of the tower body 10. The tower support 20 is connected to a detection component that can slide along the height direction of the tower support 20. The detection component is equipped with multiple vibration sensors.

In this embodiment, the tower vibration monitoring equipment of the wind turbine generator set includes a tower body 10 and a tower support 20, wherein the tower support 20 is connected to the outside of the tower body 10, and a detection component that can slide along the height direction of the tower support 20 is connected to the tower support 20, and a plurality of vibration sensors are mounted on the detection component. Therefore, in this technical solution, the detection component can slide on the tower support 20, so that the vibration of different positions of the tower body 10 can be monitored by the plurality of vibration sensors mounted on the detection component, thereby improving the convenience of tower vibration monitoring. Among them, the vibration sensor can be a piezoelectric vibration sensor WV-100 or a MEMS vibration sensor MMA8451Q. Of course, other types of vibration sensors can also be used, which will not be repeated here.

The tower support 20 includes a mounting portion, and the detection assembly includes a plurality of sliding portions 30. The mounting portion is fixedly connected to the tower body 10, and the sliding portion 30 contacts the mounting portion and can slide along the height direction of the mounting portion. Specifically, the mounting portion includes a mounting frame 21 and a plurality of mounting hoops 22 connected to the mounting frame 21. The mounting hoops 22 contact the outer wall surface of the tower body 10, and the ends of the mounting hoops 22 are connected to the mounting frame 21. In this embodiment, the number of mounting hoops 22 is generally equal to the number of multiple sub-towers of the tower body 10, so that one mounting hoop 22 acts on one sub-tower to improve the stability of the tower body 10.

In the above embodiment, please refer to FIG. 2 , the sliding part 30 includes a sliding arm 31 and two telescopic arms 32, the two telescopic arms 32 are respectively arranged at both ends of the sliding arm 31 and are in contact with the side of the mounting frame 21 away from the mounting hoop 22, and the sliding arm 31 is connected to the lifting component 40 so as to drive the sliding part 30 to move up and down through the lifting component 40. In this embodiment, the lifting component 40 can drive the sliding part 30 to move up and down on the mounting frame 21, thereby adjusting the contact position of the telescopic arm 32 on the mounting frame 21, so that the vibration sensor on the telescopic arm 32 can monitor the vibration of different positions on the mounting frame 21 in a targeted manner, thereby improving convenience.

Specifically, the lifting component 40 includes a traction steel rope 41 and a fixed connection member 42, wherein the fixed connection member 42 is mounted on the traction steel rope 41 and fixedly connected to the sliding arm 31. In this embodiment, the traction steel rope 41 can pull the fixed connection member 42 by electric drive, and the sliding part 30 is driven to move up and down by the fixed connection member 42. In an optional embodiment, the fixed connection member 42 can be set as a U-shaped member with a mounting groove, and the sliding arm 31 is clamped in the mounting groove and then locked by a fastener to improve the stability between the sliding arm 31 and the fixed connection member 42.

Generally, only one sliding part 30 can be provided on a tower body 10. However, in other embodiments, multiple sliding parts 30 can be provided so that vibration monitoring can be performed at different positions on the mounting frame 21 at the same time. It is understandable that if the spacing between multiple sliding parts 30 does not need to be adjusted and they can move up and down at the same time, they can be lifted and lowered by only one driving member. Of course, it is also possible to provide driving members at the top and bottom respectively, and then connect multiple sliding parts 30 in groups, so that different lifting logics can be adopted between the two groups for adaptation to further improve convenience.

In the above description, a plurality of anchors 50 may be provided at the bottom of the installation frame 21 to fix the installation frame 21 , so as to reduce the vibration risk of the tower body 10 .

The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the concept of the present invention, or directly/indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
