[0042] The orientation terms used in the following description are all the directions shown in the figures, and do not limit the specific structures of the anti-pollution device, drive assembly, and wind turbine generator set of the present utility model. In the description of the present utility model, it should also be noted that unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0043] As Figure 1 , Figure 2 shown, an embodiment of the present application provides a wind turbine generator set, including a wind turbine foundation, a tower 2, a nacelle 3, a generator 4, an impeller 5, a cooling system, and a drive assembly 1. The tower 2 is connected to the wind turbine foundation, and the wind turbine foundation can be a floating foundation or a pile foundation. The nacelle 3 is arranged at the top of the tower 2, and the generator 4 is arranged in the nacelle 3. In some examples, the generator 4 can be at least partially located outside the nacelle 3. Of course, in some examples, the generator 4 can also be at least partially located inside the nacelle 3. The impeller 5 includes a hub 501 and a plurality of blades 502 connected to the hub 501. When the wind acts on the blades 502, the entire impeller 5 is driven to rotate, and further drives the generator 4 to work to convert wind energy into electrical energy. The cooling system can be arranged in the nacelle 3, and the cooling system can cooperate with the generator 4 to cool and dissipate heat from the generator 4. The drive assembly 1 is used to connect to the cooling system and input cooling fluids such as seawater and lake water into the cooling system, so that the cooling system can exchange heat with heat-generating devices such as the generator 4 to ensure its normal operation.
[0044] At present, the power ratings of wind turbine generator sets are getting larger and larger. With the application of high-power wind turbine generator sets, the traditional air-cooling form has been limited by the space in the nacelle 3. In order to better meet the heat dissipation capacity of the corresponding components of the wind turbine generator set, the application solution of the water-cooling form has been put on the agenda and applied to the wind power industry. As a core component, the drive pump 200 is directly related to the reliability of the cooling system of the wind turbine generator set.

[0046] Based on this, an embodiment of the present application provides a drive assembly 1 to drive the heat exchange fluid to flow to the cooling system to exchange heat with heat-generating components such as the generator 4.

The filter holes 15 on the filter element 10 can allow fluid to enter the accommodation cavity 13 while blocking larger impurities outside the accommodation cavity 13, so that the fluid entering the inlet end 201 of the drive pump 200 has been filtered, reducing the probability of blockage at the inlet end 201 of the drive pump 200. By arranging the disturbance component 20 on the filter element 10 and including a rotating shaft 21 and a plurality of scraping plates 22 located in the accommodation cavity 13, and arranging the diversion component 30 outside the accommodation cavity 13 and including a plurality of diversion plates 31 arranged around the rotating shaft 21 and connected to the rotating shaft 21, the kinetic energy of ocean currents formed by continuous disturbance of fluids such as seawater and lakes can be utilized to impact each diversion plate 31, driving the rotating shaft 21 to rotate. Then, the rotation of the rotating shaft 21 drives each scraping plate 22 to rotate, and the scraping plates 22 are used to squeeze organisms, seaweeds, sediment, etc. attached to the side wall 12 of the filter element 10, preventing blockage of the filter holes 15, and further ensuring that the filtered fluid can continuously enter the inlet end 201 of the drive pump 200 and ensuring the flow rate requirement of the drive pump 200.
[0054] In some optional embodiments, for the anti-fouling device 100 provided by an embodiment of the present application, the diversion component 30 further includes an adapter sleeve 32.

[0056] For the anti-fouling device 100 provided by an embodiment of the present application, through the above settings, the adapter sleeve 32 can be used to connect a plurality of diversion plates 31 into a whole, and then each diversion plate 31 is fixedly connected to the rotating shaft 21 through the adapter sleeve 32. In this way, when assembling the anti-fouling device 100, the rotating shaft 21 connected with each cover plate can first be inserted axially X into the bottom wall 11 from one end of the accommodation cavity 13 and protrude from the bottom wall 11, and then the connecting sleeve and the whole of the diversion plates 31 are sleeved and installed on the rotating shaft 21, which can reduce the processing and assembly difficulty of the anti-fouling device 100.
[0057] In some optional embodiments, for the anti-fouling device 100 provided by an embodiment of the present application, the diversion component 30 further includes a pin shaft 33. A plurality of pin shafts 33 are spaced apart along the axial direction X of the rotating shaft 21, and each pin shaft 33 is inserted into the adapter sleeve 32 and the rotating shaft 21.

Thus, it can ensure that the filtered fluid can continuously enter the inlet end 201 of the drive pump 200, meet the flow rate requirements of the drive pump 200, and improve the reliability of the drive assembly 1.
[0083] Moreover, the wind power generation unit provided in one embodiment of the present application includes the drive assembly 1 provided in each of the above embodiments, which can ensure the cooling and heat dissipation effect and guarantee the power generation efficiency.
[0084] Although the present invention has been described with reference to the preferred embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
