In this embodiment, the platform 100 in the wind generating set tower comprises a platform body 110 and a carrier beam 120 fixed under the platform body 110, and a support structure 130 is disposed at an end of the carrier beam 120 for connecting with a tower wall 200 of the wind generating set.

In the illustrated embodiment, the platform body 110 is exemplarily illustrated as a circular structure, and two parallel load-bearing beams 120 are exemplarily illustrated below the platform body 110, in practical applications, the shape of the platform body 110 may be set according to needs, and is not limited to a circular shape, the number of the load-bearing beams 120 is not limited to two, and the arrangement form thereof is not limited to a parallel shape, and the number of the load-bearing beams 120 and the number of the corresponding support structures 130 may be set according to needs as long as the platform body 110 and the tower can be stably connected.

In this embodiment, the support structure 130 includes two parallel vertical plates 131 and a support member.

Riser 131 includes a first plate segment 1311 and a second plate segment 1312 coupled to first plate segment 1311, wherein an end wall of first plate segment 1311 is adapted to be coupled to tower wall 200, and a height of first plate segment 1311 decreases from the end wall to second plate segment 1312; the top wall of the second plate segment 1312 is a straight wall parallel to the horizontal plane, and the supporting member includes a supporting plate 132, the supporting plate 132 is fixedly connected to the top walls of the two second plate segments 1312, it can be understood that the top wall of the second plate segment 1312 is a horizontal straight wall, so that after the supporting plate 132 is fixed, the supporting plate 132 is parallel to the horizontal plane, and can horizontally support the carrier bar 120, thereby providing stable and reliable support for the platform body 110.

It should be noted that the terms top, bottom, outside, and the like as used herein are defined with reference to the platform 100 in an operating state after being connected to a tower, i.e., the height is the dimension in the vertical direction, and the outside is the side relatively far away from the center of the tower.

It can be understood that the supporting structure 130 is in an installation state, the plate surface of the vertical plate 131 is parallel to the vertical direction, and the plate surface of the supporting plate 132 is parallel to the horizontal direction.

During actual installation, the outer end faces of the two vertical plates 131 of the supporting structure 130 are directly welded and fixed to the tower wall 200 of the tower.

As above, the supporting structure 130 provided by this embodiment is approximately a half-box beam structure compared with the currently used circular column structure, and two parallel vertical plates are used to replace the circular column, so that the two vertical plates 131 can be directly welded and fixed with the tower wall 200, and no hole needs to be formed in the tower wall 200, thereby reducing the process difficulty and avoiding the influence of the welding defect possibly existing at the hole forming position of the tower wall 200 on the main structure of the tower. Meanwhile, due to the structural design that the height of the first plate section 1311 of the vertical plate 131 close to the tower cylinder wall 200 is gradually reduced from outside to inside along the radial direction of the tower, and the design that the supporting structure 130 is approximately of a half-box beam structure, the lateral load can be effectively resisted, the adverse effect on the tower cylinder wall 200 under the main load is reduced, the main load and the stress improvement caused by the platform load are released, and the strength requirement of the connecting part of the platform 100 and the tower cylinder wall 200 is met.

In addition, the above-described design of the support structure 130 has a larger bending-resistant cross section than that of a conventional circular column, and requires a smaller weight for the same bending moment, thereby reducing the weight.

In a specific embodiment, the first top wall 1a and the first bottom wall 1b of the first plate segment 1311 of the vertical plate 131 are both concave curved shapes, so that a dispersed stress transmission path is effectively provided, and stress concentration at a connection position of the first plate segment 1311 and the tower wall 200 is avoided.

The first top wall 1a and the first bottom wall 1b may be specifically arc-shaped, so that the influence of the load of the platform 100 on the tower wall 200 can be reduced more effectively.

The first top wall 1a and the first bottom wall 1b of the first plate segment 1311 may be symmetrically arranged with respect to the horizontal center line thereof, that is, the first top wall 1a and the first bottom wall 1b have the same circular arc shape. Specifically, the arc radius of the arc-shaped first top wall 1a and the arc-shaped first bottom wall 1b is greater than 150mm, and the arc radian is greater than 90 degrees, so as to effectively reduce the phenomenon of stress concentration.

It can be understood that, in actual installation, according to the application of the wind turbine generator system and the structural design of the tower, the platform 100, etc., the shapes of the first top wall 1a and the first bottom wall 1b of the first plate segment 1311 may not be consistent, and the relevant parameters of the circular arc shape are not limited to the above definition, and may also be other concave curve shapes with smooth transition.

In a specific scheme, the height of the second plate segment 1312 of the vertical plate 131 gradually increases from the end wall thereof to the first plate segment 1311, and in combination with the structure of the first plate segment 1311, it can be understood that the overall height of the vertical plate 131 gradually decreases from outside to inside along the radial direction of the tower, that is, the height of the vertical plate 131 close to the center side of the tower is smaller, and the height of the vertical plate 131 far from the center side of the tower is larger.

Meanwhile, the second plate 1312 has a through hole 1313, and the size of the through hole 1313 in the height direction gradually increases and then gradually decreases from the second plate 1312 to the first plate 1311.

After the vertical plate 131 is installed as described above, the stress on the upper and lower ends can be uniformly applied, and the stress transmission path can be effectively dispersed, and as shown in fig. 7, after the vertical load G is applied, the stress is dispersed and transmitted along the upper and lower sides of the through hole 1313, so that the situation that the stress on the upper end is too large and the stress on the lower end is too small can be prevented.

Specifically, the second plate 1312 may be designed to have a right trapezoid shape, and the end wall of the second plate 1312 is a straight wall parallel to the vertical direction, and the second top wall of the second plate 1312 is a horizontal straight wall, so that the second bottom wall of the second plate 1312 is an inclined wall structure inclined upward, as shown in fig. 6 and 7.

It is understood that, in practice, the shape of the second plate segment 1312 is not limited to the above, and may be approximately trapezoidal, the second bottom wall may be designed to be a smooth curve, the end wall may be a convex curve, and the joint between adjacent walls may be in a circular arc transition to prevent stress concentration.

As shown in fig. 6, in this embodiment, the hole walls of the through hole 1313 include an upper horizontal hole wall 11a, a lower inclined hole wall 13a, a first curved hole wall 12a connecting the horizontal hole wall 11a and an inner end (referring to an end close to the center of the tower) of the inclined hole wall 13a, and a second curved hole wall 14a connecting the horizontal hole wall 11a and an outer end (referring to an end away from the center of the tower, i.e., an end close to the tower wall 200) of the inclined hole wall 13 a.

The through hole 1313 is designed to better disperse the transmission path of the stress.

In actual arrangement, the shape of the through hole 1313 is not limited to that shown in the drawings, and can be adjusted accordingly according to actual application.

It should be noted that, in order to facilitate the description of the structure of the vertical plate 131, the vertical plate 131 is manually divided into two parts, namely, the first plate section 1311 and the second plate section 1312, and actually the vertical plate 131 is an integral structure.

In practical application, if other structures exist at the welding position of the vertical plate 131 and the tower wall 200 and need to be avoided, a notch 1314 for avoiding the structures may be arranged at the outer end of the vertical plate 131.

In this embodiment, the supporting member of the supporting structure 130 is only one supporting plate 132, and the supporting plate 132 may be fixed to the two vertical plates 131 by welding.

The support plate 132 and the carrier bar 120 of the platform body 110 may be connected by a fastener, specifically, by two bolts, and the connection stiffness is small, which can effectively reduce the stiffness coupling between the platform body 110 and the tower wall 200.
