AI Technical Summary

Problems solved by technology

When the unit encounters severe weather such as sandstorms, a large amount of sand-carrying air directly contacts the filter cotton through the louvers, and the filter cotton will be blocked by sand and dust particles in a short time, thus losing the filtering function and directly affecting the ventilation of the unit

Abstract

An embodiment of the present invention provides a filtering device, a tower door, a testing method for a tower and a tower door, the filtering device includes a supporting body, has a side wall and is enclosed by the side wall to form a hollow accommodation chamber with an opening, and the side wall There are more than two installation openings communicating with the accommodating cavity; the filter component is correspondingly arranged at at least one of the two or more installation openings. In the present invention, the filtering device has at least two sides for filtering, which can increase the effective filtering area, thereby improving the filtering efficiency of the filtering component while increasing the ventilation rate of the filtering component.

Description

technical field [0001] The invention relates to the technical field of wind power equipment, in particular to a filter device, a tower door, a tower and a testing method for the tower door. Background technique [0002] As a device that converts wind energy into electrical energy, a wind turbine mainly includes four parts: the nacelle, the generator, the impeller, and the tower. In the MW-level air-cooled unit, the tower is the most important ventilation channel, which meets the main air volume demand of the overall ventilation system of the wind turbine, realizes the ventilation and heat dissipation cycle process of the unit, and is a powerful guarantee for the safe operation of the wind turbine. [0003] The towers of each section of the fan unit are tightly connected by bolts to form a straight cylindrical structure, and the fixed platforms are designed in sections for each internal layer. The air-cooled unit mainly realizes ventilation and heat dissipation in each contr...
