[0038] As Figure 1 and Figure 2 shown, according to an embodiment of this application, a converter grid plate platform is proposed, including: a support plate 11 and a grid plate assembly 12; the support plate 11 is connected to the inner wall of the tower barrel; the grid plate assembly 12 is arranged between the support plate 11 and the inner wall of the tower barrel, the grid plate assembly 12 is connected to the support plate 11, and the grid plate assembly 12 is connected to the inner wall; the grid plate assembly 12 includes a first grid plate group 121 and a second grid plate group 122, the first grid plate group 121 is arranged on the first side of the support plate 11, and the second grid plate group 122 is arranged on the second side of the support plate 11.

[0039] The converter grid plate platform provided by the embodiment of this application includes a support plate 11 and a grid plate assembly 12. The support plate 11 is fixedly connected to the inner wall of the tower barrel. The grid plate assembly 12 is arranged between the support plate 11 and the inner wall of the tower barrel, forming a heat-dissipating platform for staff to stand on, which can effectively dissipate the heat generated by the operation of the converter, thereby reducing the temperature of the converter and the tower base, being beneficial to maintaining the safe and stable operation of the wind turbine generator set, and further providing guarantee for the safe operation of the unit.

[0040] In a feasible implementation manner, the converter grid plate platform is located above the converter.

[0041] In this technical solution, by making the platform above the converter have a heat-dissipating function, the chimney effect is utilized to dissipate the heat of the grid plate platform to reduce the temperature of the converter, and the heat of the tower base is also diffused through the chimney effect, effectively reducing the temperatures of the converter and the tower base of the wind turbine generator set, avoiding the long-term operation of the tower base equipment in a high-temperature environment, ensuring the safety of the tower base equipment work, and extending the service life of the equipment.

[0042] In a feasible implementation manner, the support plate 11 is formed by cutting the original platform of the converter.

[0043] In this technical solution, the support plate 11 is cut from the original platform of the AC device. A grid plate assembly 12 is installed at the position of the original platform of the AC device to directly form a grid plate platform, without the need to disassemble, position, build, and fix the support plate 11 again, reducing the installation difficulty of the grid plate platform and improving the construction efficiency of the grid plate platform.

[0044] It can be understood that before installing the grid plate platform, the original platform needs to be removed first. The original platform is cut first, and only the connection between the support plate 11 and the inner wall of the tower barrel is retained, and all the remaining structures except the support plate 11 are removed.

[0045] Furthermore, when installing the grid plate platform, as Figure 1 shown, first hoist and lay the first grid plate group 121 at the position between the right side of the support plate 11 and the inner wall of the tower barrel, connect the first grid plate group 121 to the support plate 11 with fasteners, and then use fasteners to connect the first grid plate group 121 to the inner wall of the tower barrel to complete the installation of the first grid plate group 121; then hoist and lay the second grid plate group 122 at the position between the seat side of the support plate 11 and the inner wall of the tower barrel, connect the second grid plate group 122 to the support plate 11 with fasteners, and then use fasteners to connect the second grid plate group 122 to the inner wall of the tower barrel to complete the installation of the second grid plate group 122.

[0046] As Figure 1 shown, in a feasible implementation manner, the support plate 11 is arranged perpendicular to the axis of the tower barrel, and the support plate 11 extends along the radial direction of the tower barrel; the center line of the support plate 11 coincides with the first radial line 13 of the tower barrel, and the support plate 11 is a symmetric structure with the first radial line 13 as the axis of symmetry.

[0047] In this technical solution, the support plate 11 is strip-shaped, and the support plate 11 is horizontally arranged in the tower barrel and extends along the radial direction of the tower barrel to increase the length of the support plate 11, so that the grid plate assembly 12 and the support plate 11 have a larger joint length, improving the firmness and reliability of the connection between the grid plate assembly 12 and the support plate 11; the center line of the support plate 11 coincides with the first radial line 13 of the tower barrel, and the support plate 11 is a symmetric structure with the first radial line 13 as the axis of symmetry. On the one hand, it can make the support plate 11 bear force more evenly, which is beneficial to increasing the bearing capacity of the support plate 11 and maintaining the stability and reliability of the support plate 11 itself. On the other hand, the support plate 11 is a symmetric structure with the first radial line 13 as the axis of symmetry, so that the areas of the first grid plate group 121 and the second grid plate group 122 on both sides of the support plate 11 are more consistent, making the bearing capacities of the first grid plate group 121 and the second grid plate group 122 equivalent, and improving the structural stability of the grid plate platform.

[0048] Further, a support rod is provided on the side of the support plate 11 close to the converter, and the support rod is perpendicular to the first radial line 13 to reinforce the support plate 11 and further enhance the bearing capacity of the support plate 11.

The receiving groove 15 is provided on the outer edge where the grid plate assembly 12 is in contact with the inner wall of the tower barrel and is recessed inward to form a space for receiving the cable box. On the one hand, it avoids the cable box interfering with the normal installation of the grid plate platform and reduces the installation difficulty of the grid plate assembly 12; on the other hand, the cooperation between the cable box and the receiving groove 15 can play a role in positioning the grid plate assembly 12, which is beneficial to the rapid and accurate assembly of the grid plate platform and improves the installation efficiency of the grid plate platform.

[0051] As Figure 1 shown, in a feasible implementation, the converter grid plate platform further includes: a relief opening 16, which is provided through the support plate 11.

[0052] In this technical solution, by providing the relief opening 16 on the support plate 11, it is convenient to perform maintenance on the cable box through the relief opening 16 in the future; the relief opening 16 is provided on the support plate 11 to ensure the integrity of the structure of the grid plate assembly 12, reduce the impact on the bearing capacity of the grid plate assembly 12, and ensure that the self - structure strength of the grid plate assembly 12 is not damaged.

[0053] It can be understood that during maintenance, the staff should preferably stand on the support plate 11 to prevent the grid plate assembly 12 from being damaged due to severe deformation and reduce potential safety hazards during the maintenance process.

[0054] As Figure 1 shown, in a feasible implementation, the converter grid plate platform further includes: a platform flap 17, which covers the relief opening 16. The first end of the platform flap 17 is detachably connected to the first grid plate group 121, and the second end of the platform flap 17 is rotatably connected to the second grid plate group 122.

[0055] In this technical solution, the platform flap 17 is used to close the relief opening 16. The first end of the platform flap 17 is detachably connected to the first grid plate group 121, and the second end of the platform flap 17 is detachably connected to the second grid plate group 122. One end of the platform flap 17 close to the first grid group can be turned upward to open, so as to facilitate the maintenance of the cable box in the receiving groove 15 of the first grid group through the relief opening 16.

[0056] As Figure 1 shown, in a feasible implementation, the first grid plate group 121 and the support plate 11 are arranged on the same horizontal plane. The first grid plate group 121 includes a first grid plate 1211 and a second grid plate 1212. The first grid plate 1211 and the second grid plate 1212 are connected by fastening. The joint line of the first grid plate 1211 and the second grid plate 1212 is on the second radial line 14 of the tower barrel; the second grid plate group 122 and the support plate 11 are arranged on the same horizontal plane. The second grid plate group 122 includes a third grid plate 1221 and a fourth grid plate 1222. The third grid plate 1221 and the fourth grid plate 1222 are connected by fastening. The joint line of the third grid plate 1221 and the fourth grid plate 1222 is on the second radial line 14 of the tower barrel; wherein, the second radial line 14 is perpendicular to the first radial line 13.

[0057] In this technical solution, each grid plate 120 group is composed of two spliced grid plates 120, that is, the grid plate assembly 12 includes a total of four grid plates 120. The grid plates 120 are fixedly connected by fastening between them, so as to realize the partition installation of the grid plate platform, reduce the hoisting and installation difficulty of the grid plate assembly 12, and reduce the labor intensity of workers.

[0058] As Figure 3 and Figure 4 shown, in a feasible implementation, the grid plate 120 includes: a grid 120a, a fixing frame 120b, and a reinforcing rod 120c; the fixing frame 120b is wound around the outside of the grid 120a along the circumferential direction of the grid 120a; the reinforcing rod 120c is attached to the grid 120a, the reinforcing rod 120c is perpendicular to the axis of the tower barrel, the reinforcing rod 120c is perpendicular to the first radial line 13, and both ends of the reinforcing rod 120c are connected to the fixing frame 120b at the same time.

[0059] In this technical solution, the grid 120a is laid inside the fixed frame 120b, and the grid 120a is fixedly connected to the fixed frame 120b. The fixed frame 120b is used to connect fasteners to install and fix the grid plate 120. By arranging a reinforcing rod 120c at the bottom of the grid 120a to effectively support the grid 120a, and by an operator stepping on the reinforcing rod 120c, the grid 120a is prevented from being severely deformed, strengthening the load-bearing capacity of the grid plate 120 itself, and thus being beneficial to strengthening the overall load-bearing capacity of the grid plate platform.

[0060] Furthermore, the fixed frame 120b includes two straight rod segments and an arc segment. The two straight rod segments are vertically arranged and connected at their first ends, and the two ends of the arc segment are respectively connected to the second ends of the two straight rod segments to form a closed frame structure.

[0061] As Figure 1 shown, in a feasible implementation manner, the curvatures of the arc segments of the first grid plate 1211, the second grid plate 1212, the third grid plate 1221, and the fourth grid plate 1222 are equal.

[0062] In this technical solution, the tower barrel is cylindrical, the inner wall of the tower barrel is arc-shaped, and the shape of the outer edge of the arc segment of the grid plate 120 is adapted to and arc-shaped with the shape of the inner wall of the tower barrel to reduce the difficulty of installing the grid plate 120 on the tower barrel. By making the curvatures k1 of the first arc segment, k2 of the second arc segment, k3 of the third arc segment, and k4 of the fourth arc segment the same, the arc segments of the four grid plates 120 can be continuously cut and formed from a raw material of a fixed frame 120b without separately processing four arc segments, reducing the manufacturing and processing difficulty of the grid plate 120 to improve the processing efficiency.

[0063] Furthermore, the arc segments of the four grid plates 120 are all circular arcs. Since the curvatures of the four arc segments are the same, the radii of the four grid plates 120 are equal. As Figure 1 shown, in
