Embodiment Construction
[0022] In order to make the technical means, creative features, goals and functions achieved by the present invention clearer and easier to understand, the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments:
[0023] The present invention proposes a method for designing the transmission chain support of a tandem double-wind turbine wind turbine, which is characterized in that it includes the following steps,
[0024] (1) Type selection of drive chain support for tandem double wind turbine wind turbines; due to the aerodynamic influence between the front and rear wind turbines of tandem double wind turbines, the distance between the front and rear wind turbines is regulated, so the double wind turbine The support form of the front and rear transmission chains of the unit adopts the support form of a horizontal axis single wind turbine unit with three points of support (such as image 3 (a): single main beari...

The invention provides a design method for transmission chain support of a tandem double-wind-wheel wind turbine generator which comprises the following steps: transmission chain support model selection; determining main shaft diameters of front and rear transmission chains; calculating main shaft diameters of front and back transmission chains by a direct method; solving a main shaft span when the main shaft of the front transmission chain has the minimum deflection and a main shaft length permissible range of the rear transmission chain by an iterative method; calculating a main shaft span of a rear transmission chain by using the resultant moment in the gravity center direction as zero; and determining a support form according to a transmission chain total length constraint condition. By transmission chain support type selection, main shaft diameter determination, main shaft span when a front transmission chain main shaft has the minimum deflection and a rear transmission chain main shaft length permissible range, then the rear transmission chain main shaft span is calculated, and a support form is determined according to a transmission chain total length constraint condition; and the supporting form of the transmission chain of the horizontal shaft type double-wind-wheel wind generating set can be rapidly and effectively designed.
Description
technical field [0001] The invention relates to the field of wind power generation, in particular to a design method for a transmission chain support of a tandem double wind turbine wind turbine unit. Background technique [0002] Energy is the driving force for social progress and a necessary material for the development of a country. The issue of "energy crisis" has attracted more and more attention. The shortage of energy has led people to turn their attention to renewable energy. Wind energy, as a kind of renewable energy, is inexhaustible and inexhaustible. It has developed rapidly in recent years. In order to realize the large-scale and low-cost utilization of wind energy, the capacity of wind turbines at home and abroad is moving towards large capacity. The development of the unit has brought many challenges to the existing wind power technology system, and it is difficult to improve the wind energy utilization rate of the single wind turbine unit. The development of ...
