Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0017] figure 1 , image 3 with Figure 4 A structural schematic diagram of an embodiment of the present invention is given, and it can be seen from the drawings that the present invention is a wind power generating set nacelle.
[0018] The components of the nacelle of the wind turbine are arranged in a detachable manner. The main body 2 of the nacelle of the nacelle of the wind turbine has a platform 5 on the top surface. And the empennage panel 1 is separated from the cabin main body 2 into several mutually detachable parts, and the ventilation cover 3 and the empennage panel 1 are installed on the platform 5 on the top surface of the nacelle main body by fasteners; during transportation, the ventilation cover 3 and the empennage panel 1 It is disassembled and transported, and the ventilation cover 3 and the empennage panel 1 are installe...

The invention relates to a distribution mode for components of a wind generating set engine room, which adopts a detachable distribution mode. The engine room main body of the wind generating set engine room is provided with a platform on the top surface thereof; because of the platform, the top surface of the engine room main body has a planar non-full circle section structure; a ventilation hood and a tail wing plate are separated from the engine room main body to form a plurality of mutually detachable parts and are arranged on the platform on the top surface of the engine room main body through fasteners; and the ventilation hood and the tail wing plate are detached to be transported in the transportation process and arranged on the engine room main body by the fasteners on the spot. A circle segment area is formed between the outlet of the ventilation hood and the tail wing plate. The circle segment area forms a negative pressure area when the air flows through the ventilation hood and the platform on the top surface of the engine room. When flowing along the curve wall of the ventilation hood to the outlet of the ventilation hood, the airflow outside the engine room generates pressure gradient because of the existence of the circle segment area, and the separated space forms the negative pressure area because of no filling airflow.
Description
technical field [0001] The invention relates to a device arrangement method and structure of a generator set. Specifically, it is a component arrangement and structure of a wind turbine nacelle, which is mainly used for high-power horizontal axis compact wind turbines. Background technique [0002] In recent years, with the rapid growth of my country's economy, the contradiction of national power supply shortage has become more and more prominent. Therefore, in addition to hydropower, wind power generation is the most mature, large-scale and most commercial development prospect in the development and utilization of renewable energy. It has also developed rapidly in recent years. Wind power generation mainly includes generators, blades, towers and other parts, wherein the generator is installed in the nacelle, and the nacelle is used to wrap the entire generator. Because most of the wind turbines developed in my country that can be used for commercial operation in the past a...
