Description

Filter boxes for wind turbines

technical field

The utility model relates to a filter box, in particular to a filter box for wind power generators, belonging to the technical field of wind power.

Background technique

The wind turbine will continuously generate heat during operation. In order to avoid the high internal temperature of the generator, the generator is generally designed with a cooling structure. Now the commonly used cooling method is air cooling, that is, through the cooling enclosure inside the generator A closed air path for air circulation is formed, wherein, in order to ensure the cleanliness of the air, a filter device is usually arranged at the air inlet, and this filter device is usually called a filter box.

The existing filter box structure is shown in Figure 1, including a bottom box 10 and a cover plate 20. The bottom box has an open top structure, and a number of ventilation holes for heat dissipation are opened on the side walls and bottom of the bottom box. The inner cavity of the bottom box is used for The filter cotton is placed, the cover plate covers the top opening of the bottom box, and the cover plate and the bottom box are fastened together by bolts and nuts. When installing the filter cotton in the existing filter box, it is necessary to first place the filter cotton in the inner cavity of the bottom box, and then fix the cover plate to the bottom box through fasteners (bolts and nuts). Removing the bolts and nuts to disassemble the cover plate from the bottom box, and then removing the filter cotton from the bottom box is cumbersome and inefficient.

Utility model content

In view of the problems in the prior art, the utility model provides a filter box for a wind power generator, which can realize the quick disassembly and assembly of filter cotton and improve the operation efficiency.

For realizing the above technical purpose, the technical scheme of the present utility model is:

A filter box for wind turbines, comprising a bottom box and a cover plate, the bottom box and the cover plate are welded into one body, a accommodating space for placing filter cotton is formed between the bottom box and the cover plate, the bottom box and the cover plate There are several square ventilation holes for heat dissipation, and there are insertion holes and guide holes on the cover plate. The insertion hole is located in the middle of the length direction of the cover plate. The cross-section of the insertion hole is a figure-eight shape. Smooth connection, two guide holes are provided, both of which are arranged in the middle of the width direction of the cover plate and are respectively located on both sides of the insertion hole, and the two guide holes do not pass through. The utility model has a simple structure, and by arranging an insertion hole and a guide hole on the cover plate of the filter box, the filter cotton can be quickly disassembled and assembled, and the operation efficiency can be improved. The hole is inserted, and then the filter cotton is quickly dragged and guided from the guide holes on both sides to be laid in the accommodating space. When the filter box is replaced with the filter cotton, it is only necessary to pull out the filter cotton from the insertion hole. In addition, by improving the shape of the insertion hole, the present invention can reduce the resistance of the filter cotton from the insertion hole into the accommodating space under the guide hole on the one hand, and is more conducive to guiding the filter cotton inserted into the top of the insertion hole to the guide hole for storage. It can further improve the working efficiency. On the other hand, the airflow in the filter box can be smoothly exported to the outside of the filter box, which is beneficial to the airflow to dissipate heat more efficiently.

As a preferred solution, an arc-shaped guide plate is provided on the edge of the insertion hole, and the arc-shaped guide plate is smoothly connected with the top of the insertion hole. Such arrangement is beneficial to guide the filter cotton to the top of the insertion hole, so that the filter cotton can be installed into the filter box more conveniently.

As a further preferred solution, the front side and the rear side of the insertion hole are provided with pulling holes, and the pulling holes are communicated with the insertion holes. When the filter box replaces the filter cotton, the existence of the arc guide plate on the edge of the insertion hole will hinder the upward drag of the filter cotton by fingers or other grasping tools, which is not conducive to the removal of the filter cotton from the filter box. , When replacing the filter cotton in the filter box, you can first pull the filter cotton out of a corner from the pull hole that is easier to drag the filter cotton upwards, and then automatically drive the filter cotton out of the insertion hole.
