A blocking plate 503 is fixedly provided on the side of the air duct 501 close to the one-way valve 504.

[0041] Optionally, the top of the exhaust port 2 is snap-connected with a first sealing strip 4, the bottom of the air inlet 6 is snap-connected with a second sealing strip 19, the top of the filter box 8 is fixedly provided with a mounting frame 9, and the top of the mounting frame 9 is connected to the bottom of the air inlet 6 by screws.

[0042] The embodiment of the present application can ensure the sealing of the air outlet 2 and the air inlet 6 by providing the first sealing strip 4 and the second sealing strip 19, and is not prone to air leakage.

[0043] In some embodiments of the present application, the limiting assembly 17 includes a pressing frame 1701 , a blocking bar 1702 , a sliding plate 1703 and a limiting rod 1704 .

[0044] Among them, the inner walls of both sides of the pressing frame 1701 are fixedly provided with baffles 1702, and the insides of the two baffles 1702 are respectively slidably connected with slide plates 1703, and two limiting rods 1704 are fixedly provided on one side of the slide plate 1703, and the limiting rods 1704 are slidably connected to the pressing frame 1701, and both sides of the air inlet 6 are provided with limiting grooves 7 that are engaged and connected with the limiting rods 1704.

[0045] When in use, the pull button 1707 on the outside of the slide plate 1703 can be pulled to compress the spring 1706, and the two limit rods 1704 connected to the slide plate 1703 can be driven to slide into the inner side of the pressing frame 1701, so that the limit rods 1704 can be pulled out of the limit groove 7, so that the pressing frame 1701 can be easily removed; at the same time, after the pull button 1707 is released, the spring 1706 can support the slide plate 1703 under the elastic force of the spring 1706, and the limit rods 1704 can be pushed into the limit groove 7, so that the pressing frame 1701 can be limited. The installed pressing frame 1701 can limit the top of the plate filter element 18 to prevent it from floating vertically, so as to maintain its stability.

[0046] In some embodiments of the present application, a baffle frame 10 is provided around the inner top of the filter box 8, the bottom end of the plate filter element 18 overlaps with the top end of the baffle frame 10, the top end of the plate filter element 18 overlaps with the bottom end of the pressure frame 1701, and a bottom frame 11 is fixed to the bottom end of the filter box 8 by screws, and a rubber frame 12 is fixedly connected to the inside of the bottom frame 11.

[0047] During installation, the plate filter element 18 in the filter box 8 is limited between the retaining frame 10 and the pressing frame 1701. By setting the retaining frame 10 on the filter box 8, the bottom end of the plate filter element 18 can be limited to ensure its stability. At the same time, by disassembling the bottom frame 11, the vibration motor 15 inside the filter box 8 can be easily removed for maintenance.

[0048] In an optional embodiment, a support plate 14 is fixedly provided at the bottom end of the vibration motor 15, the filter screen 13 is a steel screen, and meshes are evenly provided on the steel screen, so that air can enter normally, the bottom end of the support plate 14 is welded to the middle of the top end of the filter screen 13, and the top end of the vibration motor 15 is welded with an inclined panel 22 through a vertical plate 23, and a beating and vibrating dust assembly is provided on the inclined panel 22. The inclined panel 22 can prevent dust from falling directly on the surface of the vibration motor 15 when beating and vibrating the plate filter element 18.

[0049] Optionally, the ash beating and vibrating assembly includes a shaking spring 16 , a swing rod 24 , a beating plate 25 , a supporting rod 20 and a supporting plate 21 .

[0050] Among them, four support rods 20 are evenly arranged on the inclined plate 22, the bottom end of the support rod 20 is fixedly connected to the top end of the inclined plate 22, and a support plate 21 is arranged on the upper section of the support rod 20. The upper section of each support rod 20 is sleeved with a shaking spring 16, the bottom end of the shaking spring 16 is fixedly connected to the support plate 21, and the upper section of the shaking spring 16 is sleeved with a swing rod 24, and a flapping plate 25 is arranged on the top of the swing rod 24, wherein the top end of the shaking spring 16 is fixedly connected to the bottom end of the flapping plate 25, and the top end of the flapping plate 25 abuts against the bottom end of the plate filter element 18. In the embodiment of the present application, the swing rod 24 and the support rod 20 are arranged coaxially in the vertical direction, but are not directly connected, but are indirectly connected by the shaking spring 16, and a gap is left between the two to achieve a shaking effect.

[0051] In the embodiment of the present application, the bottom of the shaking spring 16 can be limited by the support plate 21 and the support rod 20, and the top of the shaking spring 16 can support the flapping plate 25 through the swing rod 24. When the vibration motor 15 is turned on, the shaking spring 16 can flap the plate filter element 18 through the flapping plate 25 when it shakes, so as to achieve the flapping and cleaning of the plate filter element 18 and avoid excessive dust on the plate filter element 18 affecting the use effect.

[0052] When the wind turbine cooling device provided by the embodiment of the present application is in use, the air exhaust port 2 and the air inlet 6 can ensure the circulation of air inside and outside the cabin 1. The staff exhausts the air inside the cabin 1 through the exhaust fan 3, so that the cabin 1 is in a negative pressure state, and the air flow is realized in the cabin 1. The external air can enter the cabin 1 through the air inlet 6, and the airflow with rising heat can be discharged through the air duct 501 of the protective component 5. The setting of the one-way valve 504 can prevent the backflow of the airflow, so as to cool the wind turbine inside the cabin 1. After the exhaust fan 3 stops working, the one-way valve 504 can prevent dust and foreign matter from entering the cabin 1 through the air exhaust port 2.

[0053] During the cooling process, the filter 13 and the plate filter element 18 can perform double filtering on the dust in the airflow, thereby keeping the airflow entering the cabin clean and preventing dust from contaminating the wind turbine inside the cabin 1. When the staff regularly vibrates the filter 13 through the vibration motor 15, the inclined panel 22 can transmit the vibration to the shaking spring 16. The shaking spring 16 can beat the plate filter element 18 through the slapping plate 25, thereby cleaning the filter 13 and the plate filter element 18 at the same time. The inclined panel 22 can prevent dust from falling directly on the surface of the vibration motor 15, ensuring the ventilation capacity of the filter 13 and the plate filter element 18, and avoiding the phenomenon of heat accumulation inside the cabin 1 due to poor ventilation. When the vibration motor 15 is working, the rubber frame 12 can prevent the exciting force of the vibration motor 15 from being directly transmitted to the filter box 8, thereby maintaining the stability of the filter box 8.

[0054] When it is necessary to remove the plate filter element 18, the staff first removes the screws on the mounting frame 9 of the filter box 8 and removes the filter box 8 from the air inlet 6 of the cabin 1. After the filter box 8 is removed, the plate filter element 18 in the filter box 8 can be quickly taken out, and the limit assembly 17 does not need to be removed.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it.
