Problems solved by technology

[0002] At present, the commonly used wind turbine support structures in engineering are single-tube steel cylinder or tower + steel cylinder. Both structures use giant steel cylinders on the top to connect with wind turbines, resulting in large stress concentration at the connection nodes, and secondary bends. The moment is obvious, which is not conducive to the force of the structure, and the size of the giant steel cylinder can easily reach tens of meters, the transportation is more difficult, the weight is heavy, and the construction is difficult

Embodiment Construction

[0033] In the present invention, unless otherwise expressly specified and limited, the terms "installed", "connected", "connected", "fixed" and other terms should be understood in a broad sense, for example, it may be a fixed connection or a detachable connection , or integrated; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between the two elements. References in this application to "first," "second," and similar words do not denote any order, quantity, or importance, but are merely used to distinguish the different components. Likewise, words such as "a" or "an" do not denote a quantitative limitation, but rather denote the presence of at least one. In the implementation of this application, "and / or" describes the association relationship between associated objects, indicating that there can be three kinds of relationships, for example, A and / or B, whi...

Abstract

The invention relates to the technical field of fan installation, and particularly discloses a steel tube tower type fan combined structure which comprises a fan cabin, a distributed flange connecting structure, a steel tube steel frame and a climbing device installed on the steel tube steel frame which are sequentially connected from top to bottom. A manhole is formed in the distributed flange connecting structure, and the axis of the manhole is arranged in the vertical direction. The bearing performance is good, stress concentration can be effectively avoided, transportation and installation are convenient, and cost is saved.

Description

technical field [0001] The invention relates to the technical field of fan installation, and more particularly, to a combined structure of a steel pipe tower fan. Background technique [0002] At present, the commonly used fan support structures in engineering are single-tube steel cylinder or tower + steel cylinder type. Since the top of the two structures is connected to the wind turbine by a giant steel cylinder, there is a large stress concentration in the connecting nodes, and the secondary bending The moment is obvious, which is not conducive to the stress of the structure, and the size of the giant steel cylinder can often reach tens of meters, which is difficult to transport, has a large self-weight, and is difficult to construct. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a combined structure of a steel pipe tower fan, which has good bearing performance, can effectively avoid stress concentration, is...
