[0037] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. 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.

[0038] Figure 1 A schematic diagram of the structure of a wind turbine nacelle operation assisting device provided in an embodiment of the present application.

[0039] Reference Figure 1 As shown, the wind turbine cabin operation auxiliary device provided in the present application includes multiple support plates 100 and at least one support railing 200, two adjacent support plates 100 are rotatably connected, and one of the two adjacent support plates 100 rotates relative to the other to fold or unfold each other.

[0040] The support rail 200 is rotatably disposed on one side of the support plate 100 . The support rail 200 is configured to rotate relative to the support plate 100 to stand on the support plate 100 when the support plate 100 is unfolded.

[0041] At least two support plates 100 are provided with a first connection portion 110 and a second connection portion 120 at both ends thereof, respectively. The first connection portion 110 is used for clamping with a cross beam of a base of the cabin, and the second connection portion 120 is used for abutting with the base.

[0042] It should be noted that the two adjacent support plates 100 are rotatably connected. When the operator needs to perform maintenance, the two adjacent support plates 100 are unfolded to form a working platform. When the maintenance is completed, the two adjacent support plates 100 are folded to each other for quick storage, which saves the placement space of the device, is simple to operate, and improves work efficiency.

[0043] Furthermore, by rotating the support railing 200 on one side of the support plate 100, when the support plate 100 is unfolded, the support railing 200 is rotated relative to the support plate 100 so that the support railing 200 stands on the support plate 100, thereby providing better protection and improving the safety of the device.

[0044] For example, when the support railing 200 stands on the support plate 100 , it can be upright or inclined, and the present application does not impose too many restrictions on this.

[0045] Exemplarily, there may be one or more support rails 200 , and the present application does not impose too many restrictions on the number of support rails 200 .

[0046] Furthermore, by providing the first connection portion 110 and the second connection portion 120, an installation position is provided for the support plate 100, which facilitates the connection of the support plate 100 with the base of the cabin.

[0047] Specifically, after the support plates 100 are unfolded, the first connecting part 110 is first clamped with the crossbeam of the base of the cabin, and then the second connecting part 120 is abutted with the base, so that the base of the cabin provides support for both ends of the support plate 100, thereby realizing the connection between the support plate 100 and the base, thereby providing a safe working platform for the operating personnel.

[0048] In some embodiments, reference Figure 1 As shown, the first connection portion 110 is a limiting groove, and the limiting groove is clamped with the crossbeam of the base.

[0049] It should be noted that the limiting groove is easy to be clamped with the crossbeam of the base, is easy to use, and further improves work efficiency.

[0050] In some embodiments, reference Figure 1 As shown, each support plate 100 has a limiting groove at its end on the same side.

[0051] It can be understood that by providing limiting grooves at the ends of the same side of each support plate 100, each support plate 100 is clamped with the crossbeam of the base, thereby improving the connection strength between the support plate 100 and the crossbeam and further ensuring the reliability of the device.

[0052] In some embodiments, reference Figure 1As shown, the second connection portion 120 is a support end, and the support plates 100 located at the front and rear portions extend outwardly of the remaining support plates 100 to form support ends, which abut against the base.

[0053] It should be noted that, by providing a support section on the support plate 100 and abutting the support section against the base, the base provides support for the support plate 100 .

[0054] It should also be noted that support sections are provided on the support plates 100 at the head and tail, so that both the head and tail of the device can be supported by the support plates 100, thereby ensuring the stability of the device.

[0055] At the same time, the support plates 100 at the front and rear extend outward from the remaining support plates 100 , that is, the remaining support plates 100 are shorter than the support plates 100 at the front and rear, thereby providing avoidance space for the equipment to be repaired and other surrounding equipment.

[0056] In some embodiments, reference Figure 1 As shown, at least two first connecting members 130 and at least two second connecting members 140 are respectively provided on opposite sides of the support plate 100, and two adjacent support plates 100 are rotatably connected through one of the first connecting members 130 and the other of the second connecting members 140, so that the two adjacent support plates 100 can be folded or unfolded with each other.

[0057] Exemplarily, the number of the first connector 130 and the number of the second connector 140 may be two or more, respectively, as long as the number of the first connector 130 is consistent with the number of the second connector 140 , and the present application does not impose too many restrictions on this.

[0058] Specifically, by providing the first connecting member 130 and the second connecting member 140 , two adjacent support plates 100 are rotatably connected, thereby realizing that the two adjacent support plates 100 can be folded and unfolded with each other.

[0059] In some embodiments, reference Figure 1 As shown, the first connecting member 130 and the second connecting member 140 are connected via a rotating shaft.

[0060] Specifically, the rotating shaft passes through the first connecting member 130 and the second connecting member 140 to realize the rotation connection between the first connecting member 130 and the second connecting member 140, so that two adjacent supporting plates 100 can be folded and unfolded with each other.

[0061] Figure 2 for Figure 1 Schematic diagram of the structure from another angle.

[0062] In some embodiments, reference Figure 1 and Figure 2As shown, at least two third connecting members 150 are disposed on the support plate 100 , and a fourth connecting member 210 is disposed on the support rail 200 . The fourth connecting member 210 passes through each of the third connecting members 150 in sequence to be rotatably connected with the support plate 100 .

[0063] Exemplarily, there may be two or more third connecting members 150 , and the present application does not impose excessive restrictions on the number of the third connecting members 150 .

[0064] Specifically, the third connecting member 150 is provided on the support plate 100 to provide a connection position for the support railing 200. The fourth connecting member 210 is passed through each third connecting member 150 in sequence, thereby realizing the rotation connection between the support railing 200 and the support plate 100.

[0065] In some embodiments, reference Figure 1 and Figure 2 As shown, the support railing 200 includes a first support rod 220, a second support rod 230, a first connecting rod 240 and a second connecting rod. The first connecting rod 240 and the second connecting rod are located between the first support rod 220 and the second support rod 230, and are connected to both the first support rod 220 and the second support rod 230.

[0066] The second connecting rod forms the fourth connecting member 210 , and the second connecting rod passes through each of the third connecting members 150 in sequence to be rotatably connected to the support plate 100 .

[0067] Specifically, by providing the first support rod 220, the second support rod 230, the first connecting rod 240 and the second connecting rod to form the support railing 200, a better protective effect can be achieved.

[0068] Furthermore, the second connecting rod passes through each of the third connecting members 150 in sequence, so that the support railing 200 is rotatably connected to the support plate 100 .

[0069] In some embodiments, reference Figure 1 and Figure 2 As shown, there are two support rails 200, and the two support rails 200 are respectively arranged on the support plates 100 located at the front and rear. A plurality of stoppers 160 are also arranged on the support plates 100. The stoppers 160 are constructed so that when the support rails 200 stand on the support plates 100, each stopper 160 abuts against the first support rod 220 and the second support rod 230 respectively.

[0070] It should be noted that by respectively arranging support rails 200 on the support plates 100 at the front and rear, the protective effect of the device is further improved, providing better protection for the operators.

[0071] It should also be noted that, by providing a stopper 160 on the support plate 100 , the support railing 200 is stopped so that the support railing 200 can stand on the support plate 100 , thereby playing a protective role.

[0072] Exemplarily, the stopper 160 may be a stopper plate standing on the support plate 100 , or other stopper structures, as long as it can abut against the first support rod 220 or the second support rod 230 , and the present application does not impose too many restrictions on this.

[0073] In some embodiments, reference Figure 1 and Figure 2 As shown, the extending direction of the first connecting rod 240 and the second connecting rod is consistent with the extending direction of the support plate 100 .

[0074] It should be noted that the extension direction of the first connecting rod 240 and the second connecting rod is consistent with the extension direction of the support plate 100, that is, the extension direction of the support railing 200 is consistent with the support plate 100. While ensuring that the adjacent support plates 100 are not affected from folding each other, the protection range of the support railing 200 is increased, further improving the safety of the device.

[0075] It can be understood by those skilled in the art that the auxiliary device for wind turbine nacelle operation provided by the present application, by setting a plurality of support plates 100 and at least one support rail 200, two adjacent support plates 100 are rotatably connected, and one of the two adjacent support plates 100 rotates relative to the other to fold or unfold each other, which saves the placement space of the device, is simple to operate, and improves work efficiency. The support rail 200 is rotatably arranged on one side of the support plate 100, and the support rail 200 is configured to rotate relative to the support plate 100 when the support plate 100 is unfolded, so as to stand on the support plate 100, which can play a good protective role and improve the safety of the device. At least two ends of the support plates 100 are respectively provided with a first connecting portion 110 and a second connecting portion 120, the first connecting portion 110 is used to clamp with the cross beam of the base of the nacelle, and the second connecting portion 120 is used to abut with the base to connect the support plate 100 with the base, thereby providing a safe working platform for the operator.
