Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model;
Fig. 2 is the structural side view of the utility model;
Fig. 3 is the structural schematic diagram of the utility model brush board.
In figure:1 Housing of heat-dissipating fan, 2 netted fixed frames, 3 electric pushrods, 4 fixed links, 5 slip rings, 6 controllers, 8 brush boards, 9 flabellums, 10 Rotating speed measring sensors, 11 driving motors, 12 snap-gauges, 13 bristles, 14 limit protrusions, 15 fixing screws.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work The every other embodiment obtained, shall fall within the protection scope of the present invention.
- 3 are please referred to Fig.1, the utility model provides a kind of technical solution:A kind of heat emission fan dedusting of Intelligent comprehensive power distribution cabinet Device includes the netted fixed frame 2 mounted on 1 both sides of Housing of heat-dissipating fan, guide rod 7 is provided at the center of netted fixed frame 2, And socket is equipped with slip ring 5 on guide rod 7, the outer end array of slip ring 5 is provided at least one brush board 8, and brush board 8 Both sides, which are integrally formed, is useful for the limit protrusion 14 of clamping snap-gauge 12, is provided with bristle 13 on snap-gauge 12, in Housing of heat-dissipating fan 1 with 7 coaxial place of guide rod is provided with flabellum 9, and flabellum 9 is using the driving rotation of driving motor 11, the outside setting of Housing of heat-dissipating fan 1 Have a pair of of electric pushrod 3, and the end of electric pushrod 3 and one of be connected on same slip ring 5 brush board 8 end it is logical The connection of fixed link 4 is crossed, controller 6 is provided on Housing of heat-dissipating fan 1, and the output end of driving motor 11 is provided with Rotating speed measring biography Electric pushrod 3, Rotating speed measring sensor 10 and driving motor 11, and 10 electricity of controller is electrically connected in sensor 10, controller 6 Property connection be mounted on power distribution cabinet inside temperature sensor.
