Abstract
The utility model discloses a wind driven generator tower connecting structure which is characterized in that an underbed platform is arranged at the upper end of an underbed, a base cylinder-shaped tower is fixed on the underbed platform. A plurality of toggle plates which are distributed in a radial mode are connected with the outer side edge of the lower end of the base cylinder-shaped tower, and the lower end of each toggle plate is connected with the underbed platform. According to the wind driven generator tower connecting structure, due to the fact that a beam and slab structure is good in bearing capacity for bending moment and shearing force generated by various actions, the toggle plates which are distributed in the radial mode and strengthening structures which are evenly distributed on the toggle plates can effectively bear a big bending moment and shearing force of the tower under large power. In addition, due to the fact that the faces of the toggle plates and the faces of the tower are in touch with each other, thrust face of the tower is increased, and therefore stress concentration of a stress part is effectively avoided, fatigue damage is reduced, intensity of the tower is effectively improved, and buckling damage is free of being generated. Under the same stress condition, the wall thickness of the tower can be reduced, and therefore manufacturing cost is reduced and cost is saved.
Description
[technical field]
The utility model relates to the wind-driven generator tower frame linkage structure.
[background technique]
Along with Oversea wind power generation, the especially fast development of the marine wind field of high-power blower and deep water, the jacket offshore wind turbine foundation is because lightweight, and easy transportation and installation are adopted by increasing marine wind field.The blower fan tower barrel that the lasting lengthening of current lasting increasing owing to power of fan, length of blade causes maximizing continues to increase, make and be in tower cylinder bottom and the linkage structure of underframe and bear huge bending moment by top significant horizontal power * superelevation tower tube length degree, simultaneously because long-term fatigue load, the key point and the difficult point that have been designed to this structural type design of the linkage section of blower fan tower barrel and jacket frame foundation structure (underframe).
[model utility content]
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of and overcomes that linkage structure stress is concentrated and the problem of fatigue ruption, and alleviate the weight of linkage structure, the wind-driven generator tower frame linkage structure that cost is low.
The purpose of this utility model is achieved in that
The wind-driven generator tower frame linkage structure, the upper end that it is characterized in that described underframe is provided with platform chassis, basis cylindricality tower cylinder is fixed on the platform chassis, and the lower end outward edge of described basic cylindricality tower cylinder is connected with the polylith bracket that radially distributes, and the lower end of bracket is connected with platform chassis.
Aforesaid wind-driven generator tower frame linkage structure is characterized in that described bracket is provided with the reinforcement structure.
Aforesaid wind-driven generator tower frame linkage structure is characterized in that described bracket is triangle, trapezoidal, polygonal or irregular arc plate.
Aforesaid wind-driven generator tower frame linkage structure is characterized in that described reinforcement structure is stiffening rib, and the cross section of stiffening rib can be L shaped or T shape.
Aforesaid wind-driven generator tower frame linkage structure is characterized in that described reinforcement structure is reinforced block, and reinforced block is square or spherical.
The beneficial effects of the utility model are: the good bearing capacity of bending and shearing that utilizes beam and slab structure that various effects are produced, make the bracket that radially distributes, and be distributed in the large bending and shearing that reinforcement structure on the bracket can effectively be carried high-power lower tower cylinder; Owing to the plane-plane contact of bracket and tower cylinder, increase the stress surface of tower cylinder in addition, effectively avoid concentrated the reaching of stress of force part to reduce fatigue damage, and can effectively strengthen the intensity of tower cylinder, do not produce buckling failure, under same stress condition, can reduce the wall thickness of tower cylinder, reduce cost, save cost.
