Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0050] Please refer to Figures 1 to 7 ​The utility model provides a kind of power plant electrical room ventilation device with filter, including electrical room body 1, the side and top of electrical room body 1 are respectively provided with air inlet and air outlet, further include: air inlet fan 2, air outlet fan 3, air inlet box 4 and filter mechanism, air inlet fan 2 is provided with multiple, and multiple air inlet fan 2 is installed in row at air inlet, air outlet fan 3 is installed at air outlet, air inlet box 4 is communicated with the outside of air inlet, and multiple air inlet fan 2 is located in air inlet box 4, filter mechanism is arranged in air inlet box 4, for filtering the air that enters to electrical room body 1, by setting air inlet fan 2 and air outlet fan 3, can carry out air exchange ventilation to electrical room body 1 inside, make electrical room body 1 inside heat in time, by filter mechanism, the air inlet end of air inlet fan 2 can be filtered, to reduce the situation that external dust and impurities enter electrical room body 1 inside with air inlet fan 2, improve the purification degree of electrical room body 1 inside, to realize ventilation heat exchange to electrical room body 1 inside, also can avoid external dust and impurities to enter electrical room body 1 inside, improve the heat dissipation and protection of electronic equipment in electrical room body 1 inside.

[0051] In the embodiment, the filter mechanism includes a filter plate, a beating assembly, a baffle 5, an inclined plate 6, and a locking assembly. The filter plate is arranged at the input end of the plurality of air inlet fans 2 and is installed in the air inlet box 4. The filter plate includes a frame 7, a support net 8, filter cotton 9, and springs 10. The frame 7 is connected with the inner wall of the air inlet box 4. The support net 8 is installed in the frame 7 on the side close to the air inlet fan 2. The filter cotton 9 is installed in the frame 7 on the side away from the air inlet fan 2. A gap is arranged between the support net 8 and the filter cotton 9, and a plurality of springs 10 are installed in the gap. The beating assembly is arranged below the filter plate and is used for beating the filter plate. The top side wall of the air inlet box 4 is provided with a through hole for the sliding penetration of the baffle 5. The baffle 5 is inserted into the through hole. The inclined plate 6 is obliquely installed on the inner bottom wall of the air inlet box 4. The locking assembly is arranged between the air inlet box 4 and the baffle 5 and is used for locking and limiting the use position of the baffle 5. After the filter plate is used for a period of time, it needs to be cleaned. When cleaning is needed, the baffle 5 is slid downward, the air inlet of the air inlet box 4 is closed (at this time, the air inlet fan 2 is stopped), the beating assembly is turned on, and the air inlet end of the filter plate is beaten. The support net 8 can support the filter cotton 9. The vibration effect of the filter cotton 9 when beaten by the beating assembly can be enhanced by the action of the springs 10, so that the dust outside the filter cotton 9 can be beaten off. The gap between the support net 8 and the filter cotton 9 is small, that is, the length of the springs 10 is short, and the springs can have a certain elastic effect on the filter cotton 9. The dust after beating falls on the inclined plate 6 and can be collected manually by opening the baffle 5.

[0052] In this embodiment, the corresponding striking assembly includes: a support shaft 11, a striking plate 12, a driving plate 13, a spring 14, and an eccentric assembly. The support shaft 11 is parallel to the length direction of the air inlet box 4 and is fixedly installed inside the air inlet box 4. Multiple striking plates 12 are provided, and multiple striking plates 12 are rotatably installed on the support shaft 11 through a sleeve. A driving plate 13 is provided below each striking plate 12, and the driving plate 13 is fixedly connected to the sleeve. A spring 14 is provided on the upper outer side of each striking plate 12, and the spring 14 is connected to the inner top wall of the air inlet box 4 through a fixing plate. There is a gap between the striking plate 12 and the spring 14. The eccentric assembly is provided on the outer side of the driving plate 13. Through the setting of the eccentric assembly, it can continuously contact the driving plate 13. Under the action of the sleeve, the striking plate 12 can swing back and forth around the sleeve.

[0053] Additionally, the eccentric assembly includes a drive shaft 15, eccentric wheels 16, and a motor 17. The drive shaft 15 is parallel to the support shaft 11 and is also installed inside the air inlet box 4. Each drive plate 13 has an eccentric wheel 16 on its outer side, which is mounted on the drive shaft 15. The motor 17 is mounted on the outer wall of the air inlet box 4, and its output shaft passes through the outer wall of the air inlet box 4 and is coaxially connected to the drive shaft 15. The rotation of the motor 17 can rotate the drive shaft 15, thereby causing the multiple eccentric wheels 16 to rotate. When the wider of the eccentric wheel 16 is... When the side contacts the driving plate 13, the striking plate 12 is pressed up and contacts the spring 14. The spring 14 is compressed and generates elastic force. When the eccentric wheel 16 rotates to the narrower side, the striking plate 12 is pushed against the outer wall of the filter cotton 9 under the elastic force of the spring 14. The filter cotton 9 is struck by the striking plate 12. The corresponding spring 10 between the filter cotton 9 and the support net 8 is compressed and also generates elastic force, thus generating a pushing force on the filter cotton 9 again. Therefore, as the eccentric wheel 16 rotates continuously, the filter cotton 9 jumps continuously, which can better shake off the dust and impurities on the surface of the filter cotton 9.

[0054] In this embodiment, the locking assembly includes a locking bolt 18, which is threadedly installed on the outside of the top side wall of the air inlet box 4. The locking bolt 18 is threaded through the top side wall of the air inlet box 4 and inserted into the through hole. Through the threaded engagement between the locking bolt 18 and the ventilation box, the baffle 5 can be pressed against the working position. When ventilation is required, the baffle 5 can be lifted up and locked. The height of the baffle 5 can be adjusted as needed to adjust the air intake to the inside of the electrical room body 1. When it is necessary to clean the outer wall of the filter cotton 9, the baffle 5 is moved down and the inlet of the air inlet box 4 is closed. Then, the tapping assembly is turned on to tap the filter cotton 9.

[0055] It should be noted that since filter cotton 9 is a consumable part, the design of this technical solution cannot guarantee that filter cotton 9 will be effective forever. However, this technical solution can reduce the frequency of manual disassembly and replacement of filter cotton 9, extend the service life of filter cotton 9, reduce labor and filter cotton 9 replacement consumption, and improve practicality. The baffle 5 is provided with a transparent observation window 19, which can be used to observe the dust falling when filter cotton 9 is tapped. The second spring 10 in this technical solution is connected to the support net 8, but it is in contact with the filter cotton 9, which also facilitates the disassembly of filter cotton 9 when it needs to be replaced. Furthermore, a baffle is provided on the side of the second spring 10 near the filter cotton 9 to prevent the second spring 10 from directly contacting the filter cotton 9 and causing damage to the filter cotton 9.

[0056] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
