[0022] To make the purpose, technical scheme and advantages of the utility model clearer and more explicit, the utility model is further described in detail below in combination with specific implementation manners and with reference to the drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0023] As Figures 1-4As shown, the present invention proposes a ventilation and heat dissipation device for a thermal power plant, including a fan 11, an internal support frame 12 built into the fan 11, a motor 13 installed on the internal support frame 12, a fan blade shaft 14 connected to the output end of the motor 13, and a fan blade 15 sleeved on the outside of the fan blade shaft 14. The fan blade 15 and the fan blade shaft 14 are combined as a whole and controlled to rotate by the motor 13, so that the heat dissipation air is delivered through the air inlet and outlet.

[0024] The filtration mechanism includes vertical plates 21 symmetrically installed at the air inlet and outlet of the fan 11. The vertical plates 21 have a drawer 22 inside, and a movable push-pull plate 23 is placed in the drawer 22. A hollow filter screen 24 is formed in the middle of the push-pull plate 23, and a protruding connecting plate 25 is installed on the side. The two connecting plates 25 are connected by a pull rod 26.

[0025] The vibration mechanism includes a support 41 mounted on a vertical plate 21, a vibration motor 42 mounted on the support 41, and a vibration rod 43 that passes through the two vertical plates 21 connected to the output end of the vibration motor 42.

[0026] It should be noted that the combined structure of the push-pull plate 23 and the vertical plate 21 is fixed by the positioning bolt 3 at the corner. After the push-pull plate 23 is inserted into the slot 22, in order to prevent the filter screen 24 inside the push-pull plate 23 from shaking, the positioning bolt 3 is inserted into the corner of the combined structure for end-point positioning and anti-loosening.

[0027] In this embodiment, the filter structure is designed to be detachable. When in use, the filter screen 24 is attached to the channel through which the air inlet and outlet of the ventilator 11 pass. When cleaning is required, the fixing of the positioning bolt 3 can be removed, and the push-pull plate 23 can be pulled out of the groove 22 of the vertical plate 21. At this time, the two symmetrical push-pull plates 23 are combined by the positioning bolt 3 and the vibration rod 43 respectively.

[0028] The part remaining in the slot 22 is fixed at its corner by positioning bolts 3, and the part pulled out of the slot 22 is fixed by vibrating rods 43. The difference lies in the setting of the vibration mechanism. The vibrating rods 43 are driven by the vibration motor 42 to work, causing the filter screen 24 in the middle of the push-pull plate 23 to shake, cleaning the dust and impurities attached to the surface. This solves the problem of dust and impurities clogging the filter screen 24 and affecting the cleanliness of the heat dissipation air, and prevents pollution of the workshop environment.

[0029] like Figure 2 As shown, the filter structure can be directly disassembled. The push-pull plate 23 is pulled out of the groove of the vertical plate 21. Only the part of the push-pull plate 23 is combined and fixed with the vertical plate 21, while the rest is exposed and can be cleaned directly.

[0030] like Figure 3As shown, the filter structure is directly disassembled, the part left in the slot 22 is combined by the positioning bolt 3, the part drawn out of the slot 22 is combined by the vibration rod 43, the vibration rod 43 is driven to work by the vibration motor 42, the filter cover 24 in the middle of the push-pull plate 23 is shaken, and the surface of the filter cover 24 is cleaned by vibration.

[0031] As Figure 4 As shown, at least two push-pull plates 23 are installed on the vibration rod 43 at intervals, six push-pull plates 23 are provided in the application, the vibration mechanism is arranged at the diagonally symmetrical corner, the multiple push-pull plates 23 are cooperatively cleaned by vibration at different positions, and the cleaning efficiency is improved.

[0032] It should be understood that the above specific embodiments of the utility model are only used for example or explanation of the principle of the utility model, and do not constitute the limitation of the utility model. Therefore, any modification, equivalent replacement, improvement, etc. made without deviating from the spirit and scope of the utility model shall be included in the protection scope of the utility model. In addition, the appended claims of the utility model are intended to cover all changes and modifications falling within the scope and boundary of the appended claims or the equivalent forms of such scope and boundary.
