Description

Technical Field

[0001] The utility model belongs to the technical field of wind generators, and in particular relates to a wind direction regulating device for a wind generator set. Background Art

[0002] A wind turbine is a type of generator that uses wind to drive the impeller to rotate. During the use of a wind turbine, when the wind direction changes, if the wind turbine cannot adjust its direction in time, it will lose wind energy and cause unnecessary losses; and if its impeller direction is incorrect, it may also cause unnecessary load on the machine, leading to damage. Therefore, it is crucial for a wind turbine to be able to adjust the impeller direction in a timely and accurate manner to ensure its stability and safety.

[0003] The existing wind direction adjustment device of a wind turbine usually senses the change of wind direction through a wind direction sensor. The wind direction sensor transmits an electrical signal to a processor (PLC). The processor processes the signal and then transmits the signal to a controller. Finally, the controller controls the operation of the drive device to drive the impeller to turn. Since the wind turbine is prone to generate large electromagnetic interference during operation, the measurement result of the wind direction sensor will produce a large error, and thus the direction of the impeller cannot be accurately adjusted.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 4 In an embodiment of the utility model, a wind direction adjustment device for a wind turbine generator set includes a pillar 1 and a generator set body 2, a support cylinder 3 is rotatably provided on the top of the pillar 1, the top of the support cylinder 3 is fixed to the generator set body 2, an angle sensor 4 is fixedly provided on the generator set body 2, a connecting rod 5 is rotatably provided on the upper end of the angle sensor 4, and a wind vane 6 is fixedly provided on the side end of the connecting rod 5.

[0022] Preferably, in the embodiment of the utility model, the connecting rod 5 is configured as a light rod.

[0023] Specifically, when performing wind power generation, since the rotation speed of the blades determines the power generation efficiency, and the rotation rate of the blades is determined by the wind speed, placing the blades of the generator body 2 facing the wind direction will improve the power generation efficiency. When the wind direction changes, the wind flow blows the weather vane 6, and the weather vane 6 drives the connecting rod 5 to rotate. When the rotation stops, the opposite direction of the wind vane 6 can be determined as the source direction of the wind, and the angle of rotation is detected by the angle sensor 4.

[0024] Among them, a bracket 12 is fixedly provided on the generator set body 2, and a bearing 13 is fixedly provided on the bracket 12. The connecting rod 5 is rotatably matched with the angle sensor 4 through the bearing 13. By providing the bearing 13, the rotation resistance is reduced.

[0025] Furthermore, an inner cavity 7 is opened at the top of the pillar 1, and a motor 8 is fixedly installed inside the inner cavity 7. A rotating shaft 9 is fixedly installed at the output end of the motor 8. The top of the rotating shaft 9 passes through the pillar 1 and is fixedly installed with a gear 10. A gear ring 11 meshing with the gear 10 is fixedly installed on the inner wall of the support tube 3. The motor 8, the rotating shaft 9 and the gear 10 are all provided in plurality, and the plurality of gears 10 are respectively meshed with the gear ring 11.

[0026] Specifically, the motor 8 drives the rotating shaft 9 and the gear 10 to rotate, the gear 10 drives the gear ring 11 and the support tube 3 to rotate, and then drives the generator set body 2 to rotate, adjust the blade direction of the generator set body 2, and set multiple sets of gears 10 to drive at the same time, thereby increasing the power and making the rotation adjustment smoother.

[0027] In addition, a PLC controller 14 is fixedly installed on the inner side of the inner cavity 7. The PLC controller 14 is electrically connected to the motor 8 and the angle sensor 4. The multiple motors 8 all use drive motors with power-off braking devices, which are automatically controlled by the PLC controller 14. When the motor 8 is in a power-off state, the motor 8 is locked by the power-off braking device, thereby fixing the direction of the generator set body 2.

[0028] Finally, an inspection door 15 is provided on the pillar 1 at the inner cavity 7, and a lock core connected to the pillar 1 is provided on the inspection door 15. A plurality of scaffoldings 16 are fixedly provided on the pillar 1, and the plurality of scaffoldings 16 are evenly spaced. The staff climbs up through the plurality of scaffoldings 16, and then opens the inspection door 15 to inspect and maintain the interior.

[0029] The operating principle of the utility model is described as follows: when the wind direction changes, the airflow of the wind blows the weather vane 6, and the weather vane 6 drives the connecting rod 5 to rotate. When the rotation stops, the direction opposite to the wind vane 6 can be determined as the source direction of the wind, and the angle of rotation is detected by the angle sensor 4. The angle sensor 4 transmits a signal to the PLC controller 14, and the PLC controller 14 performs automatic control. The motor 8 drives the rotating shaft 9 and the gear 10 to rotate, and the gear 10 drives the ring gear 11 and the support cylinder 3 to rotate, thereby driving the generator set body 2 to rotate, and adjusting the direction of the blades of the generator set body 2 so that the blades of the generator set body 2 face the opposite direction of the wind vane 6. By setting multiple sets of gears 10 for simultaneous driving, the power is increased and the rotation adjustment is smoother.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
