The filter window is used to be installed on the tower of the wind turbine to prevent impurities and rainwater in the external environment from entering the tower. Of course, in other embodiments, the filter window can also be set on a sealing structure that needs to be ventilated and isolated from impurities and rainwater in the external environment in other application scenarios.

As shown in FIG. 1 , the filter window includes a window frame 2 , a filter device 6 , a baffle 9 and a plurality of blades 3 . Wherein, the window frame 2 can be fixed on the tower door panel 1, and a plurality of blades 3 are arranged parallel to each other on the side of the window frame 2 facing the outside of the tower tube, and both ends of the plurality of blades 3 are fixed on the window frame 2 The baffle 9 is vertically arranged at the bottom of the window frame 2 near the inside of the tower, and the filter device 6 is arranged between the plurality of blades 3 and the baffle 9 .

When the filter window is installed on the tower door panel 1 of the wind turbine, the filter device 6 is located on the rear side of the plurality of blades 3 along the incoming flow direction, and is located on the front side of the baffle plate 9 . The filter device 6 can isolate flying sand, dust and other impurities in the external environment of the tower tube, preventing them from entering the tower tube and causing pollution. In addition, when rainwater enters the rear side of multiple blades 3 due to strong winds and other reasons, the filter device 6 can prevent this part of rainwater from directly entering the inside of the tower, so that it flows down to the bottom of the window frame 2 along the filter device 6, and is blocked by the baffle 9 This part of rainwater enters the inside of the tower to prevent the normal operation of the electrical equipment inside the tower from being affected, thereby effectively solving the problem that rainwater easily enters the inside of the tower.

Specifically, the window frame 2 can be a rectangular frame, and its four peripheral sides are fixedly connected with the tower door panel 1, so that the window frame 2 can support the entire filter window. Therefore, the window frame 2 is preferably made of rigid material, such as stainless steel. The specific arrangement of the blades 3 is preferably fixed on the window frame 2 in parallel at intervals, and the ends of the plurality of blades 3 away from the filter device 6 are all lower than their ends close to the filter device 6, forming a way of slanting downward toward the outside of the tower. , which is equivalent to forming a preliminary protective layer on the filter window to prevent rainwater from easily passing through the plurality of blades 3 and entering the tower.

In a practical application scenario, if it is raining in the external environment, the filter window can use a plurality of blades 3 to tilt downward, so that rainwater falls on the inclined surfaces of the plurality of blades 3 to prevent it from entering the filter window. If the wind speed of the wind in the external environment is relatively large, part of the rainwater will enter the rear sides of multiple blades 3. At this time, the filter device 6 can isolate this part of the rainwater, and make this part of rainwater flow downward along the filter device 6, and the baffle plate 9. The rainwater flowing downward along the filtering device 6 can be blocked outside the tower tube to prevent this part of rainwater from entering the inside of the tower tube.

As mentioned above, the filter window has a simple and compact structure, similar to the blinds in the prior art, and all components in the window frame 2 can be made of relatively low-cost materials, and are easy to manufacture. For example, the plurality of blades 3 fixed on the window frame 2 are preferably welded on the window frame 2 at both ends, so that the plurality of blades 3 are stably fixed on the window frame 2, and the inclined surface formed by the plurality of blades 3 can be stabilized.
