Description
Technical field
The present invention relates to a kind of dust cover being applied on power information switch。
Background technology
Power information switch work in power system uses fan for cooling, owing to the working environment dust of part switch is more, after using for a long time, a large amount of dust can be gathered at the air inlet position of fan, the working effect making fan even quits work worse and worse, and then makes switch internal temperature raise and affect normal operation, and, dust can be sucked during fan work, cause switch to damage。It is often necessary to regularly switch is carried out cleaning work, now not only need switch to shut down, and dismounting switch bothers very much, time and effort consuming, inefficiency。
Summary of the invention
It is an object of the invention to provide a kind of fan place that can reduce power information switch or accumulated inside dust and affect the power information switch dust cover of work。
For reaching above-mentioned purpose, the technical solution used in the present invention is:
A kind of power information switch dust cover, it is arranged at the air inlet place of power information switch, described power information switch dust cover includes being internally formed the case of vent passages, being arranged in described case and cover the multilamellar Air Filter with filtering holes in described vent passages cross section, the external port of described vent passages is connected with the external world, the inner port of described vent passages is connected with described air inlet, and the aperture of the filtering holes of Air Filter described in multilamellar is different。
Preferably, described case is cuboid, forms described vent passages between the two sides that described case is relative, and the four additional side of described case constitutes the housing around described vent passages, and described Air Filter is installed on described housing。
Preferably, described case offering and described Air Filter opening one to one, described Air Filter is inserted in described case by described opening。
Preferably, offer in described case when described Air Filter inserts described case its chute led。
Preferably, the external port of described vent passages is made up of the multiple through holes being opened on described case；The inner port of described vent passages is formed by the rectangular opening being opened on described case。
Preferably, the plurality of described through hole is matrix form arrangement。
Preferably, the aperture of described through hole is more than the aperture in maximum filtering hole。
Preferably, by described external port to described inner port direction, on each described Air Filter, the aperture of filtering holes is gradually reduced。
Preferably, described Air Filter includes having the main part of some described filtering holes, be surrounded on described main part periphery and support the framework of described main part。
Preferably, described case is outside equipped with the adhesive piece at the air inlet place being fixed in described power information switch。
Owing to technique scheme is used, the present invention compared with prior art has the advantage that the dust entering switch can be filtered by the dust cover of the present invention effectively, thus avoiding the impact on fan of the fan place dust accretions, it also avoid dust and entering switch and impact on wherein parts。It is convenient to use, time saving and energy saving, can be greatly prolonged the service life of switch fan by it, is greatly improved the stability of switch work, extends the length of service of switch。

Detailed description of the invention
Below in conjunction with embodiment shown in the drawings, the invention will be further described。
Embodiment one: as shown in accompanying drawing 1 to accompanying drawing 6, the power information switch dust cover at a kind of air inlet place being arranged at power information switch, including case 1 and multilamellar Air Filter 2。
Case 1, in cuboid, adopts transparent acrylic to make。Two sides being oppositely arranged of case 1, one of them offers multiple through hole 3 arranged in matrix form, another then offers rectangular opening 4, thus, vent passages is defined between the side that the two is relative, in matrix form, the through hole 3 of arrangement is formed for the external port of vent passages, and rectangular opening 4 forms the inner port of vent passages。The four additional side of case 1 constitutes the housing around vent passages。
Multilamellar Air Filter 2 is arranged in case 1, and every layer of Air Filter 2 all can completely cover vent passages cross section。Air Filter 2 includes having the main part 5 of some filtering holes, be surrounded on the framework 6 of main part 5 periphery supportive body part 5。Multilamellar Air Filter 2 is arranged successively along by the direction of the inside port of vent passages external port, every layer of Air Filter 2 is toward being respectively provided with the filtering holes that aperture is identical, and the aperture of filtering holes is different on multilamellar Air Filter 2, by the inside port direction of the external port of vent passages, on each Air Filter 2, the aperture of filtering holes is gradually reduced, and on case 1 aperture of through hole 3 more than the aperture in maximum filtering hole。In the present embodiment, it is provided with two-layer Air Filter 2。
Owing to Air Filter 2 needs completely covering vent passages cross section, therefore Air Filter 2 is arranged on the housing of vent passages。Housing is made up of four sides of case 1, and the side, side of the case 1 of composition housing offers and Air Filter 2 opening 7 one to one, and opening 7 sidepiece also has attacker position 8, thus Air Filter 2 can be inserted in case 1 by corresponding opening 7。And the inner side of housing, then corresponding opening 7 is provided with when Air Filter 2 inserts case 1 its chute 9 led。When Air Filter 2 inserts and puts in place, the position of Air Filter 2 is also acted as restriction effect by chute 9, places Air Filter 2 and offsets so that it is can cover the cross section of vent passages all the time。
This dust cover is arranged on the air inlet place of power information switch fan。The both sides of the inner port of, vent passages outer at case 1, are provided with the adhesive piece 10 at the air inlet place being fixed in power information switch。After dust cover installs, the external port of vent passages is connected with the external world, and the inner port of vent passages is connected with air inlet。When the fan work of switch, air is by the external port of vent passages, and namely the through hole 3 of matrix form arrangement enters in case 1, sequentially passes through the filtration of multistorey strainer mesh, and finally by the inner port of vent passages, namely the rectangular opening 4 on case 1 enters air inlet。Such that the most dusts in air can be intercepted outside switch, it is to avoid the fan place dust accretions impact on fan, it also avoid dust and enter switch and impact on wherein parts。In use for some time, Air Filter 2 can be extracted out by opening 7, carries out clearing up or changing。This dust cover is convenient to use, time saving and energy saving, can be greatly prolonged the service life of switch fan by it, is greatly improved the stability of switch work, extends the length of service of switch。
Above-described embodiment only for technology design and the feature of the present invention are described, its object is to allow person skilled in the art will appreciate that present disclosure and to implement according to this, can not limit the scope of the invention with this。All equivalences made according to spirit of the invention change or modify, and all should be encompassed within protection scope of the present invention。
