Problems solved by technology

Since the connection between the support and the transition section is not coherent, the load transmitted to each support is not uniform, so it is easy to have a large stress concentration at the connection point at the upper end of the support

Embodiment Construction

[0030] like Figure 1 to Figure 6b As shown, the improved connection structure of the transition section between the wind turbine tower and the foundation includes the fan foundation 2. There is a reinforcement ring 5, the inner side of the reinforcement ring 5 is connected to the outer wall of the transition section 3, the circumference of the lower side of the reinforcement ring 5 is connected to the foundation platform 2 through multiple supports, and the connection point between the outer side of the upper end of the support and the reinforcement ring 5 is close to the outer circumference of the reinforcement ring 5 . The support can be a column diagonal support 6 (see Figure 2b ) or bracket support 4 (see Figure 2a ).

[0031] like image 3 As shown, the reinforcement ring 5 is located above the middle of the transition section 3, and below the reinforcement ring 5, there is another support connection between the outer circumference of the transition section and the...

Abstract

The invention discloses an improved connection structure for a WTGS tower and a basic connection transition section. The structure comprises a comprises a fan base provided with a basic platform; the transition section connected with the tower is arranged on the basic platform; a reinforcing ring is arranged on the transition section; the inner side of the reinforcing ring is connected with the outer wall of the transition section; and the lower side of the reinforcing ring is connected with the basic platform through a plurality of supports. The invention aims at providing the improved connection structure for the WTGS tower and the basic connection transition section. According to the improved connection structure, the reinforcing ring is added in a connection position of the transition section and the supports and is connected with the supports and the transition section directly, therefore, the connection rigidity between the upper ends of the supports and the transition section is enhanced, the load of a fan can be transmitted uniformly to each support, the stress concentration in the connection position of the upper ends of the supports and the transition section is reduced, and the bending and torsion resistant capacities of the tower and the basic connection transition section are improved.

Description

【Technical field】 [0001] The invention relates to a connection structure between a tower tube of a wind power generating set and a jacket foundation, in particular to an improved connection structure for a transition section between a tower tube of a wind power generating set and a foundation, and belongs to the field of wind power generation. 【Background technique】 [0002] Offshore wind power is vigorously developed. In order to make good use of offshore wind resources and save costs, the installed capacity of offshore wind turbines is increasing. The application of large megawatt wind turbines has become a trend in the development of offshore wind power. As the installed capacity of a single unit increases, the structural size of the unit also increases, and the requirements for the bearing capacity of the tower and the foundation are also higher. Therefore, the way of strengthening the support is often used in the transition section between the tower and the foundation. ...
