Examples

Referring to fig. 1 and 2, an embodiment of the utility model provides a multifunctional detection device 6 for detecting an operation condition of a wind turbine. In use, the multifunctional detection device 6 is adapted to be mounted adjacent to the tail vane 5 of a wind turbine. The multifunctional detection device 6 comprises a driving assembly 61, a transmission assembly 62 and a detection assembly 63. Wherein the driving assembly 61 is fixedly mounted at the tail rudder 5 of the wind turbine. The tail rudder 5 attached to the wind turbine is attached to the wind turbine in the vicinity of the tail rudder 5. The transmission assembly 62 includes a driving member 621 and a driven member 622, the driving member 621 is fixedly connected to the output end of the driving assembly 61, and the driven member 622 is rotatably disposed around the tail rod 4 of the wind turbine. For example, the driving component 61 may be a motor, which can output torque, and the driving member 621 is connected to the output end of the driving component 61, and can rotate under the torque and drive the driven member 622 to rotate around the tail rod 4 of the wind turbine. The detecting member 63 is fixedly mounted on the follower 622.

The multifunctional detection device 6 obtained through the design comprises a driving component 61, a transmission component 62 and a detection component 63, wherein the driving component 61 is fixedly installed at the tail rudder 5 of the wind driven generator, the transmission component 62 comprises a driving part 621 and a driven part 622, the driving part 621 is fixedly connected with the output end of the driving component 61, the driven part 622 is rotatably and annularly arranged on the tail rod 4 of the wind driven generator, and the detection component 63 is fixedly installed on the driven part 622. On one hand, the tail vane is arranged at the position of the wind driven generator close to the tail vane 5, which is beneficial to ensuring that the loads at two sides of the tower frame 1 of the wind driven generator are more uniform; on the other hand, the detection assembly 63 is arranged on the driven part 622, the driven part 622 can be arranged on the wind driven generator in a rotating mode, when the detection assembly 63 is used, the driven part 622 can drive the detection assembly 63 to rotate around the tail rod 4 of the wind driven generator, therefore 360-degree detection of the detection impeller 2 part and the detection nacelle 3 part is achieved in the circumferential direction, fault conditions of the impeller 2 and the nacelle 3 and the connection part of the impeller 2 and the nacelle 3 can be found out in an early stage, and early troubleshooting and maintenance of faults are achieved.

In some embodiments, referring to fig. 2, the driving member 621 includes a gear, the driven member 622 includes a gear ring engaged with the gear, the gear is disposed inside the gear ring, and the gear ring is disposed around the tail rod 4 of the wind turbine. Specifically, an annular gap is formed between the inner surface of the gear ring and the outer surface of the tail rod 4, and the driving part 621 can be placed in the annular gap. Further, the ring gear is a structure having both ends penetrating in the axial direction, and the length direction of the output shaft of the drive unit 61 extends in the axial direction of the ring gear, and is fixedly connected to the gear inside the ring gear. With the above structure, the driving member 621 rotates to drive the driven member 622 to rotate around the tail rod 4 of the wind turbine. While the diameter of the driving member 621 is significantly smaller than that of the driven member 622, the output angular velocity of the driving assembly 61 is equal to that of the driving member 621, and the linear velocity of the driving member 621 is equal to that of the driven member 622, so that the angular velocity of the driving member 621 will be significantly greater than that of the driven member 622. In other words, the angular velocity of the follower 622 is significantly less than the output angular velocity of the drive assembly 61, i.e.: the transmission assembly 62 has a speed reduction function, so that the driven member 622 can rotate around the tail rod 4 relatively slowly, and detection is facilitated.

In some embodiments, the multifunctional detecting device 6 further comprises a driven mounting part 64, the driven mounting part 64 is used for being fixedly connected with the wind driven generator, specifically, the driven mounting part 64 comprises two connecting rods 643 in a rod shape, and the end parts of the connecting rods 643 are fixedly connected with the tail rod 4 of the wind driven generator.

The driven mount 64 is provided to help stabilize the position of the driven member 622 during rotation, and to provide smoother rotation of the driven member 622.

In some embodiments, a bearing 642 is disposed in the mounting cavity 641, an outer surface of the bearing 642 is fitted to an inner wall of the mounting cavity 641, and an inner surface of the bearing 642 is fitted to an outer ring of the ring gear.

Further, the solar cell panel 65 may be fixedly attached to the tower 1. The solar cell panel 65 can function as the driving unit 61 and the detecting unit 63. Further, the solar cell panel 65 is electrically connected to a storage battery, and the storage battery is electrically connected to the driving assembly 61 and the detecting assembly 63.

The nacelle 3 is connected to the top of the tower 1, components such as a rotor and a stator required for power generation can be arranged in the nacelle 3, one end of the nacelle 3 is fixedly connected with the impeller 2, and the rotor in the nacelle 3 can be driven to rotate through rotation of the impeller 2. The other end of the engine room 3 is fixedly connected with one end of a tail rod 4, and one end, far away from the engine room 3, of the tail rod 4 is connected with a tail rudder 5 and a multifunctional detection device 6. Specifically, the tail rudder 5 is a plate-like structure disposed substantially in the vertical direction.

In some embodiments, the driving assembly 61 and the tail rudder 5 of the multifunctional detecting device 6 are respectively arranged on both sides of the tail rod 4. For example, the length direction of the tail rod 4 extends substantially in the horizontal direction, the tail rudder 5 is provided on the upper side of the tail rod 4, and the drive assembly 61 is provided on the lower side of the tail rudder 5. This arrangement makes the drive assembly 61 contribute to lowering the center of gravity of the tail rod 4, the tail rudder 5, and the drive assembly 61 as a whole, and contributes to making the wind turbine generator as a whole more stable.
