[0031] This application provides a platform working device and a wind turbine generator set. The platform working device and the wind turbine generator set of this application will be described in detail below with reference to the accompanying drawings. Without conflict, the features in the following embodiments and implementation manners can be combined with each other.

[0032] Figure 1 The three-dimensional schematic diagram of a wind turbine generator set 100 according to an exemplary embodiment of this application is shown. Refer to Figure 1 As shown, this application provides a wind turbine generator set 100, including a tower barrel 20, a nacelle 30 rotatably assembled on the top of the tower barrel 20, blades 40 arranged at one end of the nacelle 30, and a platform working device 10 installed on the wind turbine generator set 100 (refer to Figure 2 shown). One end of the platform working device 10 is arranged on the tower barrel 20 of the wind turbine generator set 100, and the other end extends outward from the tower barrel 20 and can be used for cleaning and repairing the blades 40 of the wind turbine generator set 100.

[0033] Figure 2 The plan view of a platform working device 10 according to an exemplary embodiment of this application is shown. For the convenience of the following description, please refer to the accompanying drawings, including a first direction X, a second direction Y, and a third direction Z, where the first direction X, the second direction Y, and the third direction Z are perpendicular to each other in pairs. In the embodiment of this application, the height direction of the tower barrel 20 is defined as the first direction X, and the length direction of the nacelle 30 is defined as the second direction Y.

[0034] Refer to Figure 2 As shown, this application provides a platform working device 10, which can be applied to scenarios that require climbing, such as a wind turbine generator set 100 and a utility pole. This application takes the application to a wind turbine generator set 100 as an example for description. Among them, the platform working device 10 includes a working platform 11 and a displacement mechanism 12.

[0035] The working platform 11 is used for cleaning and repairing the blades 40. The working platform 11 described above can be a platform for carrying people, or a cleaning device capable of realizing automatic cleaning and repairing functions. The shifting mechanism 12 is connected between the tower 20 and the working platform 11, and is used to change the working position of the working platform 11, wherein one end of the shifting mechanism 12 is arranged on the tower 20. In some cases, the end of the shifting mechanism 12 connected to the tower 20 can be fastened to the tower 20. In other cases, the end of the shifting mechanism 12 connected to the tower 20 can also move upward or downward along the height direction of the tower 20. The other end of the shifting mechanism 12 extends outward from the tower 20 and is connected to the working platform 11, so that the position of the working platform 11 relative to the blade 40 can be changed by the movement of the shifting mechanism 12.

[0036] The displacement mechanism 12 includes a first displacement mechanism 121, and the first displacement mechanism 121 includes an amplitude change driving mechanism 1211 and at least two folding arms 1214. The folding arms 1214 are used to connect the tower 20 and the working platform 11, and can play a role in supporting the working platform 11. At least two adjacent folding arms 1214 can be connected to rotate relative to each other, so that the two adjacent folding arms 1214 can rotate relative to each other, which is convenient for the working platform 11 to achieve position change. The amplitude change driving mechanism 1211 is connected between at least two adjacent folding arms 1214, and can output a force acting on the folding arms 1214. The thrust or pulling force acts on the folding arms 1214, and is used to drive the folding arms 1214 to rotate so as to realize the movement of the working platform 11 on the plane where the first direction X and the second direction Y are located. In this embodiment, the amplitude change driving mechanism 1211 can be a hydraulic cylinder with advantages such as small size and impact resistance, or it can be other linear driving mechanisms with impact resistance, large output force and stable operation. The variable amplitude driving mechanism 1211 includes an extended state and a contracted state. The variable amplitude driving mechanism 1211 realizes the swing of the folding arm 1214 by switching between the extended state and the contracted state, and finally realizes the movement of the working platform 11 relative to the tower 20.

[0037] With such a configuration, the displacement mechanism 12 connected to the tower 20 can be used to realize the movement of the working platform 11 on the plane where the first direction X and the second direction Y are located. This facilitates the cleaning and repair of the blades 40 arranged on the tower 20, and can solve the problems of cleaning and maintenance difficulties of the blades 40 arranged on the wind turbine generator set 100. Compared with the working method of cleaning and repairing the blades 40 by Spiderman, it is safer and simpler and more convenient to operate.

[0038] In some embodiments, at least two folding arms 1214 include a first folding arm 1215 and a second folding arm 1216. The first end of the first folding arm 1215 is used for rotatably connecting to the tower barrel 20, such that the first folding arm 1215 can rotate relative to the tower barrel 20. The second end of the first folding arm 1215 is rotatably connected to the first end of the second folding arm 1216, such that the first folding arm 1215 and the second folding arm 1216 can rotate relative to each other. The second end of the second folding arm 1216 is connected to the working platform 11, such that when the first folding arm 1215 and the second folding arm 1216 rotate relative to each other, the position of the working platform 11 changes. The luffing drive mechanism 1211 includes a first luffing drive mechanism 1212. One end of the first luffing drive mechanism 1212 is rotatably connected to the first folding arm 1215, and the other end is rotatably connected to the second folding arm 1216. The first luffing drive mechanism 1212 is used for driving the second folding arm 1216 to rotate. The contraction of the first luffing drive mechanism 1212 can drive the second end of the second folding arm 1216 to rotate towards the direction close to the first folding arm 1215, so as to realize the folding of the first position-changing mechanism 121; the elongation of the first luffing drive mechanism 1212 can drive the second end of the second folding arm 1216 to rotate towards the direction away from the first folding arm 1215, thereby realizing the unfolding of the first position-changing mechanism 121. In this way, the movement of the working platform 11 in the plane where the first direction X and the second direction Y are located can be realized.

[0039] In some embodiments, at least two folding arms 1214 further include a third folding arm 1217. The second folding arm 1216 is connected to the working platform 11 through the third folding arm 1217. The second end of the second folding arm 1216 is rotatably connected to the third folding arm 1217, such that the second folding arm 1216 can rotate relative to the third folding arm 1217. The luffing drive mechanism 1211 further includes a second luffing drive mechanism 1213. One end of the second luffing drive mechanism 1213 is rotatably connected to the second folding arm 1216, and the other end is rotatably connected to the first end of the third folding arm 1217. The second luffing drive mechanism 1213 is provided for driving the third folding arm 1217 to rotate. The second end of the third folding arm 1217 is connected to the working platform, such that when the third folding arm 1217 and the second folding arm 1216 rotate relative to each other, the position of the working platform 11 changes. In this way, the elongation and contraction of the second luffing drive mechanism 1213 can drive the third folding arm 1217 to rotate, such that the second end of the third folding arm 1217 can make a pitching motion relative to the second folding arm 1216, such that the working platform 11 can reach more positions, and better realize the cleaning and repair of the blade 40.

[0040] In some embodiments, the slewing mechanism 12 further includes a slewing drive mechanism 1218. One end of the slewing drive mechanism 1218 is used to connect to the tower barrel 20 and is rotatable relative to the tower barrel 20, and the other end is rotatably connected to the first folding arm 1215. The slewing drive mechanism 1218 can be a linear motion mechanism such as a hydraulic cylinder. The extension and contraction of the slewing mechanism cause the first folding arm 1215 to rotate relative to the tower barrel 20, so that the working platform 11 can move to more positions. In other embodiments, the slewing drive mechanism 1218 can also be a support arm fixedly connected between the first folding arm 1215 and the tower barrel 20, so that the position of the first folding arm 1215 is fixed relative to the tower barrel 20, enhancing the overall reliability of the slewing mechanism 12.

[0041] In some embodiments, the slewing mechanism 12 further includes a platform drive mechanism 1219. The third folding arm 1217 is rotatable relative to the working platform 11. One end of the platform drive mechanism 1219 is rotatably connected to the third folding arm 1217, and the other end is connected to the working platform 11 and is rotatable relative to the working platform. Wherein, one end of the platform drive mechanism 1219 connected to the working platform 11 and the second end of the third folding arm 1217 are respectively arranged on both sides of the working platform 11 along the first direction X, preventing the extension and contraction of the platform drive mechanism 1219 from making the movement stability of the working platform 11 poor. The extension and contraction of the platform drive mechanism 1219 can adjust the rotation angle of the working platform 11 relative to the third folding arm 1217. During the rotation of the folding arm 1214, the working platform 11 is kept horizontal at all times, ensuring the safety performance of the platform working device 10.

[0042] The rotatable connection methods mentioned above can be hinge connections, pivot connections and other relative rotation methods, which are not limited in this application.

[0043] In this embodiment, the first end of the first folding arm 1215 is connected to the tower barrel 20 and can rotate relative to the tower barrel 20. The second end of the first folding arm 1215 is hinged to the first end of the second folding arm 1216. The second end of the second folding arm 1216 is hinged to the third folding arm 1217, and the second end of the third folding arm 1217 is hinged to the second displacement mechanism 122. One end of the displacement drive mechanism 1218 is connected to the tower barrel 20 and can rotate relative to the tower barrel 20. The other end of the displacement drive mechanism 1218 is hinged to the first folding arm 1215. One end of the first luffing drive mechanism 1212 is hinged to the first folding arm 1215, and the other end of the first luffing drive mechanism 1212 is hinged to the second folding arm 1216. One end of the second luffing drive mechanism 1213 is hinged to the second folding arm 1216, and the other end of the second luffing drive mechanism 1213 is hinged to the first end of the third folding arm 1217. One end of the platform drive mechanism 1219 is hinged to the third folding arm 1217, and the other end of the platform drive mechanism 1219 is hinged to the work platform 11. In this way, the movement of the work platform 11 in the plane where the first direction X and the second direction Y are located can be realized, which is convenient for the work platform 11 to reach each position in this plane, and the cleaning and repair of each position of the blade 40 can be realized.

[0044] Figure 3 The following shows a schematic diagram of another plane direction of the platform working device 10 according to an exemplary embodiment of the present application. Refer to Figure 3 As shown, in some embodiments, the displacement mechanism 12 includes a second displacement mechanism 122, and the second displacement mechanism 122 extends from the first displacement mechanism 121 along a third direction Z perpendicular to the first direction X and the second direction Y; the second displacement mechanism 122 is connected between the work platform 11 and the first displacement mechanism 121. Among them, the second displacement mechanism 122 is used to realize the movement of the work platform 11 in the third direction Z, that is, the movement of the work platform 11 along the width direction of the blade 40 can be realized, so that the work platform 11 can reach more positions and better clean and repair each area of the blade 40.

[0045] In some embodiments, the second displacement mechanism 122 includes a telescopic driving device 1221 and a telescopic arm 1222. Among them, the telescopic driving device 1221 is a linear driving mechanism such as a hydraulic cylinder with a large output force and stable operation. The telescopic arm 1222 includes a first telescopic arm 1223 and a second telescopic arm 1224 movably arranged along the third direction Z on the first telescopic arm 1223. In this embodiment, the second telescopic arm 1224 is inserted through the first telescopic arm 1223 and can move relative to the first telescopic arm 1223 along the third direction Z. The first telescopic arm 1223 is connected to the first displacement mechanism 121, and the second telescopic arm 1224 is connected to the working platform 11. One end of the telescopic driving device 1221 is connected to the first telescopic arm 1223, and the other end is connected to the second telescopic arm 1224. The telescopic driving device 1221 can drive the first telescopic arm 1223 or the second telescopic arm 1224 to move, so as to realize the position change of the working platform 11 in the third direction Z.

In this embodiment, the displacement mechanism 12 is arranged at the top of the climbing mechanism 13, which is convenient for the extension and contraction of the displacement mechanism 12. In some cases, the climbing mechanism 13 can be fixedly arranged on the tower barrel 20, and in other cases, the climbing mechanism 13 can also move up or down along the height direction of the tower barrel 20.

[0047] In some embodiments, the climbing mechanism 13 includes a first embracing portion 131 and a second embracing portion 132 arranged relatively along the first direction X, and a first driving mechanism 133 connected between the first embracing portion 131 and the second embracing portion 132, the first embracing portion 131 and the second embracing portion 132 are arranged around the tower 20, the first embracing portion 131 and the second embracing portion 132 can be arranged around the circumference of the tower 20, at least partially in contact with the outer surface of the tower 20, one end of the first driving mechanism 133 is connected to the first embracing portion 131, and the other end is connected to the second embracing portion 132. In this embodiment, the first embracing portion 131 is arranged close to the top of the tower 20 relative to the second embracing portion 132, and the first displacement mechanism 121 is connected to the first embracing portion 131. The number of the first driving mechanisms 133 disposed between the first embracing portion 131 and the second embracing portion 132 is not limited, so that there is sufficient force to push the displacement mechanism 12 and the working platform 11 disposed on the second embracing portion 132, and the first driving mechanisms 133 can be evenly disposed along the circumference of the tower 20, so as to improve the balance and stability of the climbing mechanism 13. When one of the first embracing portion 131 and the second embracing portion 132 is in the above-mentioned embracing state, the other can move along the tower 20, and when both the second embracing portion 132 and the first embracing portion 131 are in the above-mentioned embracing state, the climbing mechanism 13 is fixedly disposed on the tower 20, thereby fixing the entire platform operation device 10 on the tower 20.

The number of the second driving devices is two, and they are respectively disposed at both ends of the first part 1311 around the circumferential direction of the tower barrel 20. When the second driving mechanism is in the extended state, the first clamping portion 131 is in the open state. When the second driving mechanism is in the contracted state, the inner surface of the first clamping portion 131 is in close contact with the outer surface of the tower barrel 20, so that the first clamping portion 131 is in the clamped state. In other embodiments, the first clamping portion 131 is disposed around the circumferential direction of the tower barrel 20 and has an opening along the circumferential direction of the tower barrel 20. To form a first end of the first clamping portion 131 and a second end of the first clamping portion 131 that are separately disposed. The first clamping portion 131 can undergo elastic deformation.

When the second driving mechanism extends, the first clamping portion 131 is in an open state, and when the second driving mechanism contracts, the first clamping portion 131 is in a tightened state; when the third driving mechanism extends, the second clamping portion 132 is in an open state, and when the third driving mechanism contracts, the second clamping portion 132 is in a tightened state. In this application, the upward movement of the climbing mechanism 13 along the tower barrel 20 is taken as an example for illustration, and the downward movement is similar. When the first clamping portion 131 is in a tightened state and the second clamping portion 132 is in an open state, the first driving mechanism 133 contracts, causing the second clamping portion 132 to move in a direction closer to the first clamping portion 131, that is, the second clamping portion 132 moves upward along the tower barrel 20. When the first driving mechanism 133 is completely contracted, the second clamping portion 132 is tightened, the first clamping portion 131 is opened, and the first driving mechanism 133 extends, causing the first clamping portion 131 to move in a direction away from the second clamping portion 132, that is, the first clamping portion 131 moves upward along the tower barrel 20 until the first driving mechanism 133 is completely extended. Subsequently, the first clamping portion 131 is tightened, the second clamping portion 132 is opened, and the above actions are repeated. When the climbing mechanism 13 reaches the specified position, both the first clamping portion 131 and the second clamping portion 132 are in a tightened state. At this time, the slewing mechanism 12 can be driven to realize the change of the working position of the working platform 11.

[0051] For the related movements of the platform working device 10 in the above embodiment, such as the extension and contraction of the first driving mechanism 133, the second driving mechanism, and the third driving mechanism of the climbing mechanism 13, and the extension and contraction of the luffing driving mechanism 1211 in the slewing mechanism 12, etc., can all be controlled by wireless remote control, with high automation, facilitating operation and implementation. The power system adopts dual driving of a storage battery and an external industrial power supply, with lasting power, meeting the requirements of the complex and changeable construction site of the wind turbine generator set, and being clean and pollution-free to the environment.

[0052] In some embodiments, the working platform 11 can rotate relative to the position-changing mechanism 12 about a third direction Z perpendicular to the first direction X and the second direction Y, that is, it is rotatably arranged on the second position-changing mechanism 122. The platform working device 10 further includes a leveling mechanism 14. The leveling mechanism 14 is arranged between the position-changing mechanism 12 and the working platform 11. The leveling mechanism 14 includes a leveling motor 141. The leveling motor 141 can be a hydraulic motor. One end of the leveling motor 141 is connected to the position-changing mechanism 12, and the other end is connected to the working platform 11. Taking the working platform 11 for carrying people as an example, when the position-changing mechanism 12 adjusts the position of the working platform 11, there is a certain probability that the working platform 11 will tilt forward or backward, which is somewhat dangerous. Setting the leveling mechanism 14 can realize the rotation of the working platform 11 relative to the position-changing mechanism 12, so that the working platform 11 returns to the horizontal state.

[0053] In some embodiments, the platform working device 10 further includes a horizontal sensor 15 and a controller (not shown). The horizontal sensor 15 is arranged on the working platform 11 and is used to detect the levelness of the working platform 11. The controller is connected to the leveling motor 141 and the horizontal sensor 15. The controller controls the rotation of the leveling motor 141 according to the levelness. By detecting the inclination degree of the working platform 11 through the horizontal sensor 15 and feeding it back to the controller, the controller can control the leveling motor 141 to work, so that the working platform 11 returns to the horizontal state. With such a setting, the degree of automation is high, and it is convenient to operate and use.
