Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0036] Reference Figure 1 As shown, the auxiliary device provided in the present application for wind turbine generator set to operate outside the nacelle includes a support assembly 100 and a ladder 200 , and the ladder 200 is arranged on one side of the support assembly 100 .

[0037] The supporting assembly 100 has a slot 131 and a hanging portion 111 at opposite ends thereof, respectively. The slot 131 is used for being connected to a control cabinet bracket of the cabin, and the hanging portion 111 is used for being connected to the top of the cabin.

[0038] It should be noted that the card slot 131 and the hanging portion 111 are respectively arranged at both ends of the support assembly 100, that is, the card slot 131 is arranged at the bottom of the support assembly 100, that is, the card slot 131 is located at the edge of the support assembly 100. Figure 1 The middle arrow indicates the Y direction; the hanging portion 111 is arranged at the top of the support assembly 100, that is, the hanging portion 111 is located along the support assembly 100 Figure 1 The +Y direction is indicated by the middle arrow. First, the card slot 131 at the bottom of the support assembly 100 is connected to the control cabinet bracket of the cabin, and then the bracket part at the top of the support assembly 100 is connected to the top of the cabin. On the one hand, the control cabinet bracket of the cabin and the top of the cabin provide support for the support assembly 100, so that the ladder 200 can transmit the force it bears to the cabin through the support assembly 100. On the other hand, it prevents the support assembly 100 from detaching from the cabin, ensuring the safety of the ladder 200.

[0039] It can be understood that one side of the support assembly 100 on which the ladder 200 is arranged is connected to the cabin on the side of the support assembly 100 facing away from the ladder 200, thereby facilitating operators to carry out operations in the cabin from the side of the ladder 200 facing away from the support assembly 100, thereby solving the problem of operators stepping directly on the main control cabinet bracket or the generator bracket, which may easily damage the main control cabinet or the generator equipment.

[0040] In some embodiments, reference Figure 2As shown, the support assembly 100 includes a first support portion 110, a first connecting portion 120, a second support portion 130 and a second connecting portion 140. The first connecting portion 120 and the second connecting portion 140 are both located between the first support portion 110 and the second support portion 130, and are connected to the first support portion 110 and the second support portion 130. The end of the ladder 200 is rotatably connected to the first support portion 110.

[0041] The hanging portion 111 is disposed on a side of the first supporting portion 110 away from the ladder 200 , and the locking slot 131 is disposed on a side of the second supporting portion 130 away from the first supporting portion 110 .

[0042] Exemplarily, the first supporting portion 110, the first connecting portion 120, the second supporting portion 130 and the second connecting portion 140 may be integrally formed, or may be connected by screws, or may be connected by other means, and the present application does not impose too many restrictions on this.

[0043] Exemplarily, the length of the first support portion 110 may be equal to the length of the second support portion 130 , or may be greater than or less than the length of the second support portion 130 , and the present application does not impose too many restrictions on this.

[0044] It should be noted that the length of the first connection portion 120 is equal to the length of the second connection portion 140 so that the first support portion 110 is parallel to the second support portion 130 , thereby ensuring that the hanging portion 111 provided on the first support portion 110 is parallel to the card slot 131 provided on the second support portion 130 .

[0045] Specifically, the end of the ladder 200 is rotatably connected to the first support part 110, that is, the top of the ladder 200 is rotatably connected to the first support part 110. The ladder 200 can rotate relative to the first support part 110 to change the inclination angle of the ladder 200. On the one hand, it can improve the comfort of the operators when using the device, and on the other hand, it is convenient to store the device.

[0046] In some embodiments, reference Figure 2 and Figure 3 As shown, the extending direction of the slot 131 is consistent with the extending direction of the second support portion 130 , and two ends of the slot 131 are correspondingly connected to two ends of the extending direction of the second support portion 130 .

[0047] It should be noted that the extending direction of the card slot 131 and the first support portion 110 is along Figure 2 In the +X or -X direction indicated by the middle arrow, the two ends of the slot 131 are correspondingly connected to the two ends of the second support portion 130, so that the first support portion 110 is completely engaged with the control cabinet bracket of the cabin through the slot 131 in the extension direction, thereby improving the reliability of the engagement.

[0048] In some embodiments, reference Figure 2 As shown, the hanging portion 111 is a flange of the first supporting portion 110 toward the top of the cabin.

[0049] It can be understood that the hanging part 111 is the flange of the first support part 110, that is, the first support part 110 is hung with the top of the cabin through its flange. The flange manufacturing process is simple, convenient and easy to obtain, and has great strength, which improves the reliability of the hanging part 111.

[0050] In some embodiments, reference Figure 1 and Figure 2 As shown, the ladder 200 includes a plurality of ladder units 210 that are rotatably connected to each other in sequence. The ladder unit 210 includes a step plate 211 and two sets of telescopic components 212 . Both ends of the step plate 211 are rotatably connected to the two sets of telescopic components 212 .

[0051] It should be noted that the number of ladder units 210 can be determined according to the height in the cabin, and this application does not impose too many restrictions on this.

[0052] Exemplarily, two adjacent ladder units 210 may be hinged or connected in other ways, as long as they can rotate relative to each other, and the present application does not impose too many restrictions on this.

[0053] Specifically, the ladder unit 210 is formed by providing a step plate 211 and two sets of telescopic components 212, the two sets of telescopic components 212 are respectively provided at both ends of the step plate 211, and two adjacent telescopic components 212 are rotated and connected in sequence to form the ladder 200. By extending and retracting the telescopic components 212, not only the length of the ladder 200 can be changed, but also the spacing between the step plates 211 can be adjusted.

[0054] In some embodiments, reference Figure 2 As shown, the telescopic assembly 212 includes two S-shaped connectors 2121 , which are symmetrically cross-arranged, and one of the two S-shaped connectors 2121 rotates relative to the other to adjust the distance between two adjacent step plates 211 .

[0055] Exemplarily, the two S-shaped connectors 2121 may be hinged or connected in other ways, as long as the two S-shaped connectors 2121 can rotate relative to each other, and the present application does not impose too many restrictions on this.

[0056] It should be noted that the two S-shaped connectors 2121 are symmetrically cross-arranged, that is, the hinge point of the two S-shaped connectors 2121 is located at the center of the telescopic assembly 212, and the hinge point of the step plate 211 and the telescopic assembly 212 and the hinge points of the two S-shaped connectors 2121 are located at the same position, so that the step plate 211 is located at the center of the telescopic assembly 212.

[0057] Specifically, when the device is to be used, one of the two mutually hinged S-shaped connectors 2121 is rotated toward the other, the distance between the center points of two adjacent telescopic components 212 increases, thereby lengthening the ladder 200 and increasing the distance between two adjacent step plates 211.

[0058] Furthermore, when the device is to be stored, one of the two mutually hinged S-shaped connectors 2121 is rotated in a direction away from the other, the distance between the center points of two adjacent telescopic components 212 becomes smaller, thereby shortening the ladder 200 and reducing the distance between two adjacent step plates 211.

[0059] In some embodiments, reference Figure 2 As shown, the first support portion 110 has two third connection portions 112 , and the ladder unit 210 located at the top of the ladder 200 is hinged to the third connection portions 112 via an S-shaped connection piece 2121 .

[0060] Specifically, by providing the third connection portion 112 on the first support portion 110 , a connection position is provided for the ladder unit 210 .

[0061] It can be understood that the ladder unit 210 located at the top of the ladder 200 is hinged to the third connecting portion 112 , so that the ladder 200 can rotate relative to the third connecting portion 112 .

[0062] In some embodiments, reference Figure 2 As shown, two handrails 300 are also included. The two handrails 300 are respectively disposed on the first connection portion 120 and the second connection portion 140 , and the ladder 200 is located between the two handrails 300 .

[0063] It can be understood that by respectively providing handrails 300 on the first connection portion 120 and the second connection portion 140 , and the two handrails 300 are located on the outside of the ladder 200 , the safety of the operator when climbing the ladder 200 is ensured.

[0064] In some embodiments, reference Figure 2 As shown, two safety hanging points 400 are also included. The safety hanging points 400 are respectively located at the top of the two handrails 300, and the safety hanging points 400 are used to hang safety ropes.

[0065] It should be noted that, by providing safety hanging points 400 on the tops of the two handrails 300 , a position for hanging a safety rope is provided for the operator, thereby further ensuring the operator's operating safety.

[0066] In some embodiments, reference Figure 1As shown, at least one bolt is also included. The support assembly 100 has a connecting hole, and the bolt passes through the connecting hole and is connected to the threaded hole on the nacelle cover of the nacelle.

[0067] Exemplarily, there may be one or more bolts, and the present application does not impose excessive restrictions on the number of bolts.

[0068] Exemplarily, the connection hole may be disposed on the first supporting portion 110 , the first connecting portion 120 , the second supporting portion 130 , or the second connecting portion 140 , and the present application does not impose too many restrictions on the position of the connection hole.

[0069] Specifically, the support assembly 100 is connected to the nacelle cover of the nacelle by using bolts, so that the support assembly 100 is fixed to the nacelle to prevent the support assembly 100 from being separated from the nacelle, thereby further ensuring the safety of the device.

[0070] It can be understood by those skilled in the art that the auxiliary device for wind turbine generator set to exit the nacelle provided by the present application is provided with a support assembly 100 and a ladder 200, and the ladder 200 is provided on one side of the support assembly 100. The support assembly 100 has a card slot 131 and a hanging part 111 respectively provided at opposite ends thereof, and the card slot 131 is firstly connected with the control cabinet bracket of the nacelle, and then the hanging part 111 is hung with the top of the nacelle. On the one hand, the control cabinet bracket of the nacelle and the top of the nacelle provide support for the support assembly 100, so that the ladder 200 can transmit the force it bears to the nacelle through the support assembly 100, and on the other hand, the support assembly 100 is prevented from being separated from the nacelle, thereby ensuring the safety of the ladder 200. The operator starts the operation of exiting the nacelle from the side of the ladder 200 away from the support assembly 100, which solves the problem that the operator directly steps on the main control cabinet bracket or the generator bracket, and is easy to step on the main control cabinet or the generator equipment.
