Detailed Description

The following detailed description of the embodiments of the present invention is provided in connection with the accompanying drawings for the purpose of facilitating understanding and understanding of the technical solutions of the present invention. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The embodiment provides a yaw motor, as shown in fig. 1-2, which includes a housing 100, a rotating shaft 400 disposed in the housing 100 and capable of rotating relative to the housing 100, a brake 200 disposed between the housing 100 and the rotating shaft 400, the brake 200 fixed on the housing 100 and capable of braking the rotating shaft 400, a temperature sensor disposed on the brake 200, the temperature sensor connected to a processor, and the processor connected to a prompting device. The yaw motor is used for the wind driven generator, the wind wheel is mainly controlled to turn to the windward direction according to the wind vane, the wind driven generator needs to frequently adjust the direction of the wind wheel due to the frequency of the change of the wind direction, the brake 200 needs to be released in each adjustment process, and the direction of the wind wheel needs to be positioned through the brake 200 after the wind wheel is adjusted in place, so that the wind wheel is prevented from shaking. Frequent braking of the brake 200 will increase the temperature, the over-high temperature of the brake 200 easily causes the reduction of the braking effect or damages components in the yaw motor, the temperature sensor arranged on the brake 200 can monitor the temperature of the brake 200 in real time, and the operation of the yaw motor can be suspended when the temperature of the brake 200 is over-high. For example, the temperature sensor transmits temperature information to the processor, and when the processor judges that the temperature is too high, the processor automatically controls the yaw motor to pause; or the processor sends prompt information through the prompt device to inform the worker that the temperature of the brake 200 is too high, and the worker controls the yaw motor to pause working. The prompting device can be a display or a buzzer.

As shown in fig. 1-3, a junction box 300 is disposed on the casing 100, a socket 310 is disposed on the junction box 300, and the socket 310 is detachably connected to a plug 320 for connecting to a power source. When the yaw motor needs to be disassembled for maintenance, the power line needs to be disassembled from the junction box 300, the box cover of the junction box 300 needs to be disassembled in the traditional power line connection mode, then the power line is disassembled through screws, which is troublesome, and the power line is connected with the junction box 300 through the plug 320 and the socket 310, so that the yaw motor is convenient to disassemble, assemble, maintain and repair. The socket 310 is detachably mounted on the junction box 300 by screws.

The socket 310 is hinged with a buckle 311, the plug 320 is provided with a clamping column 321 corresponding to the buckle 311, and the buckle 311 can limit the clamping column 321 to prevent the plug 320 from being separated from the socket 310. Buckle 311 has two articulated portions 312 and articulates respectively in the both sides of socket 310, and the atress is even can form comparatively stable articulated like this, has joint portion 313 on buckle 311, and joint portion 313 can block post 321 card post 321 and prevent that plug 320 from breaking away from socket 310 for plug 320 and socket 310's connection is more stable firm, when the power cord is demolishd to needs, swing buckle 311, makes joint portion 313 break away from the screens to calorie post 321, then pull out plug 320 can.

The processor is positioned outside the yaw motor and inside the wind driven generator, a lead of the temperature sensor penetrates through the junction box and then is connected with the socket, the connection with the processor is realized through the matching of the socket and the plug, the junction box 300 and the temperature sensor are positioned on the same axial plane, and the axial plane is a plane parallel to the rotating shaft 400. This allows the temperature sensor to be located as close to the axial face of the junction box 300 as possible, reducing bending of the temperature sensor leads. A threading pipe 210 is arranged between the temperature sensor and the junction box 300, and the lead of the temperature sensor enters the junction box and the socket to be connected by penetrating through the threading pipe 210. The threading pipe 210 can protect the lead wire and prolong the service life of the lead wire. As shown in fig. 2, the casing 100 has fins 110, and the threading pipes 210 are partially embedded between the fins 110. The radiating fins 110 can restrain the threading pipes 210, so that the threading pipes 210 are not prone to shaking and are arranged more regularly and stably.

The shaft extension end 420 can be connected with an angle indicator only or a manual rotating tool 500 only, when the shaft extension end 420 is provided with the angle indicator, the angle indicator can display the rotating angle of the yaw motor, and when the angle indicator displays that the rotating angle of the yaw motor and the rotating angle of the wind wheel generate deviation, correction is carried out to ensure the accuracy of the steering of the wind wheel; when axle extension end 420 sets up hand instrument, can be through artifical rotatory yaw motor, be convenient for debugging and maintenance. In this embodiment, an angle indicator or manual turning tool 500 is removably coupled to the shaft extension 420. Therefore, the angle indicator and the manual rotating tool 500 can be interchanged, the rotation condition of the yaw motor is detected through the angle indicator when the yaw motor is normally used, and when the rotation angle of the yaw motor needs to be debugged, maintained or calibrated, the angle indicator can be detached and the manual rotating tool 500 is replaced.

The shaft extension 420 may be a polygonal prism and angle indicator or a polygonal slot mating connection of the hand turning tool 500 or may be a key and slot mating connection. In this embodiment, the end of the shaft extension end 420 has a semicircular cross-section, as shown in fig. 4, a corresponding mounting groove 510 is formed on the manual rotation tool 500, and when the shaft extension end 420 is inserted into the mounting groove 510, the yaw motor is driven by the manual rotation tool 500 to rotate to adjust the direction of the wind wheel.
