Embodiment Construction
[0020] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0021] The invention mainly utilizes the principle of chimney effect existing in nature, uses the heat dissipation of the power device itself as the driving force in the wind turbine, and at the same time, through the design of a long air duct, uses the principles of inertial collision, physical adsorption and gravity to realize the reduction of salt content in the external fresh air. The clean air is used to form a micro-positive pressure in the tower and the engine room, so that the mechanical and electrical components of the offshore and intertidal wind turbines are protected from salt spray corrosion, and the gap between the two "chimneys" is also fully utilized. Heat exchange enhances heat...

The invention provides a micro positive pressure generating device, which comprises a circulating air flue and a fresh air flue, wherein the lower end of the circulating air flue is provided with a hot air inlet facing a power component of a wind driven generator; and a part of the fresh air flue is accommodated in the circulating air flue, and the lower end of the fresh air flue is provided with a fresh air inlet communicated with the outer part of a tower cylinder. By using the micro positive pressure generating device in the technical scheme, fresh air is introduced to form micro positive pressure by arranging the circulating air flue and the fresh air flue accommodated in the circulating air flue, using the chimney effect and using the dissipated heat of a power device in the wind driven generator as a driving force. On the other hand, salts in external fresh air are removed by designing the long air flues and using the principles of inertial impact, physical adsorption and gravity. Therefore, the reliability of the wind driven generator is improved, and the maintenance difficulty is reduced.
Description
technical field [0001] The invention relates to the field of wind power generator equipment, in particular to a micro positive pressure generating device. Background technique [0002] When wind turbines are used in intertidal zones and offshore wind farms, they are in a marine atmospheric environment. The marine atmosphere is rich in salt, and the salt mist formed by the combination of salt and humid air will corrode the metal structural parts of the wind turbine, and it is also easy to cause electrical short circuit. If it is not prevented, it will reduce the strength of the mechanical structural components in the wind turbine and damage the electrical equipment, increase the failure rate and maintenance costs, and reduce the availability and safety of the wind turbine. [0003] In order to avoid salt spray corrosion, the important components of offshore and intertidal wind turbines should be placed inside the airtight tower or engine room as much as possible. However, t...
