Problems solved by technology

[0005] These prior art nacelles are not only complex in structure and difficult to install, but also have a weak mechanical connection between two adjacent components of the nacelle
Since the nacelle is used in a field environment with strong wind, under the action of strong wind, the nacelle with weak mechanical connection strength will be deformed or even completely damaged, resulting in the failure of the entire wind turbine to operate normally

Embodiment Construction

[0038] The nacelle 1 for a wind power generating set according to the present invention will be described in detail below with reference to the accompanying drawings. The nacelle 1 according to the invention comprises a bottom wall 3 , a first side wall 5 , a second side wall 7 opposite to the first side wall 5 , and a top wall 9 . The nacelle 1 according to the invention also comprises a rear end cover or rear end wall 11 and a not shown front end cover or front wall. These walls are interconnected to form a generally hexahedron-shaped space. Of course, openings may be formed at corresponding positions on the wall of the nacelle 1 according to the installation requirements of other components of the wind power generating set. It should be understood that the nacelle 1 according to the invention may be formed in any other suitable shape than the illustrated hexahedral shape, such as a pentahedral shape or an elliptical cylindrical shape.

Abstract

The invention provides an engine room for a wind generating set. The engine room comprises a plurality of walls, wherein the plurality of walls are mutually connected to form the internal space of the engine room. The engine room is characterized in that: a supporting beam is arranged on the internal surface of the connecting part of at least one group of adjacent walls; and the part of the supporting beam, which contacts the adjacent walls, has the shape matched with the internal surface shape of the connecting part. The engine room for the wind generating set is simple in structure, convenient in transportation, easy to install and high in mechanical connection strength.

Description

technical field [0001] The invention relates to the field of wind power generators, in particular to a nacelle for a wind power generator. Background technique [0002] With the shortage of energy and the deterioration of the environment, wind power has been paid more and more attention due to its renewable and environmentally friendly characteristics. A wind turbine for wind power generation generally includes a tower, a nacelle at the top of the tower, and a wind rotor at one end of the nacelle. The engine room is usually equipped with a transmission system, a braking system, a yaw system, a control system, and a generator. Increasingly larger wind turbines require ever larger nacelles, which makes transport and installation of the nacelles increasingly difficult. To solve this problem, the nacelle is usually not a monolithic structure, but consists of multiple parts that can be assembled together. [0003] For example, WO2007 / 132408 discloses a nacelle for a wind power...
