Problems solved by technology
Although this solution can solve the connection problem between the small unit and the supporting structure, in order to meet the connection stiffness, it is difficult to reduce the weight of the load-bearing connection interface structure and the auxiliary connection, and there is no connection scheme with multi-directional truss beams
CN201720888638.2 proposes a steel pipe truss type racing car frame front cabin, this scheme adopts a steel pipe truss structure, but its application is completely different from the racing field and the wind power field, and the rod structure of this scheme cannot solve multi-impeller power generation Complex connection and loading problems between the unit and the truss support structure

The invention discloses a multi-impeller wind power generation system and a bearing frame and a connecting device thereof. A first polygonal structure and a second polygonal structure are arranged in parallel, the number of edges of the two polygonal structures is the same, two connecting rods are led out of each vertex of the first polygonal structure and connected with the vertexes of the second polygonal structure respectively, and two connecting rods are led into each vertex of the second polygonal structure respectively. Each vertex forms a structural node of the bearing frame, every two connecting rods and one side of the polygonal structure form a single triangular structure, a plurality of peripheral triangular structures surrounding the polygonal structure by a circle are finally formed, the triangular structures are connected with the triangular truss beams, and the polygonal structure is connected with the wind power generation units. And the node connection requirement in the multi-impeller wind power system and the lightweight design of the nodes are realized.
Description
technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a multi-impeller wind power generation system, a bearing frame and a coupling device thereof. Background technique [0002] Wind power is the power generation method with the most large-scale development value and commercial development prospects in the field of renewable energy. The available wind energy is widely distributed around the world and has huge reserves. [0003] With the increase of the single-unit power generation capacity of wind power generation, higher design requirements are put forward for the tower tube as the supporting system, and the shortcomings of the traditional tower tube support are gradually enlarged, mainly reflected in the low overall utilization rate of materials. After the cylinder is too high, the top moves sideways, etc. Lattice steel structure towers are re-emphasized in wind turbines with a height of more than 100m. ...
