Description

Technical Field

[0001] The utility model relates to the technical field of wind power equipment, in particular to a ventilation and filtering device for a wind power tower. Background Art

[0002] Wind power equipment is equipment that uses wind energy to generate electricity or wind power. Among various types of new energy, wind power generation is one with relatively mature technology, the most favorable conditions for large-scale commercial development, and relatively low cost. Wind turbines are the most commonly used among wind power equipment, and wind turbine towers are an important component of wind turbines. They play a supporting role in wind turbines. Since there are many high-power components arranged in the tower, a lot of heat is generated during daily work, which causes the temperature inside the tower to rise. When the temperature rises to a certain level, it will affect the normal operation of the generator set. Therefore, it is necessary to install ventilation and filtration devices to achieve the effect of ventilation, heat dissipation and dust removal.

[0003] Prior art CN218130633U discloses a ventilation and filtering device for a wind turbine tower, comprising a tower body, wherein one side of the tower body is respectively provided with an air inlet and a disassembly and assembly component, an installation sleeve is provided in the air inlet, a filter box is installed on one side of the installation sleeve, a filter screen is installed inside the filter box, a cleaning component is provided in the filter box, the cleaning component comprises a driving motor and two sliding rods, a slide plate is sleeved between the two sliding rods, a cleaning brush plate is installed on one side of the slide plate, the output end of the driving motor extends to the inside of the filter box and is connected to a turntable, and a rotating plate is connected between the turntable and the slide plate via a rotating shaft. When the device cleans the dust attached to the surface of the filter, the drive motor is started to rotate the turntable and drive the turn plate to rotate, thereby pushing the slide plate to move and drive the cleaning brush plate to clean the surface of the filter. However, due to the limited rotation angle of the turn plate, the movement distance of the slide plate is small, so that the cleaning area of ​​the filter by the cleaning brush plate is small and the cleaning efficiency is low. At the same time, the device cannot process the dust that falls off the filter after cleaning, resulting in the dust still remaining in the device. When the dust accumulates too much, the ventilation efficiency of the device will be reduced, and the practicality is poor. Utility Model Content
