Abstract
The utility model provides a dustproof power box, which belongs to the field of protection devices of power equipment and comprises an outer casing and an inner casing, wherein the outer casing is provided with outer radiating holes arranged in array, and inner radiating holes are arranged in array on the face of the inner casing opposite to the outer radiating holes. A whole position of the inner radiating holes are arranged above that of the outer radiating holes, and dust discharge bottom holes are arranged at the bottom of a separating portion of the outer casing and the inner casing. The dustproof power box is capable of effectively protecting the power equipment, ensuring good heat dissipation performance and preventing dust from directly entering the casings, thereby reducing pollution of the dust to the power equipment.
Description
Affiliated technical field
The utility model relates to a kind of electric equipment protection device, particularly, is a kind of electric power bin, is suitable for to make coupling box, ring main unit, electrical equipment shell.
Background technology
For various power equipments; generally all need to adopt housing that it is protected,, need on housing, offer louvre in order to guarantee the heat radiation of power equipment; and for present housing; be the individual layer shell, so, after dust enters louvre; just will directly be scattered in the power equipment surface; thereby, make power equipment be subjected to contamination by dust, and it is aging to accelerate power equipment.
The utility model content
In order to address the above problem; the purpose of this utility model is to provide a kind of dustproof electric power case, and this dustproof electric power case not only can be protected power equipment effectively, and guarantees good heat radiation; and can prevent that dust from directly entering housing, thereby reduce the pollution of dust power equipment.
The technical scheme that its technical problem that solves the utility model adopts is: this dustproof electric power case comprises shell and inner casing; Offer the outer louvre that is matrix distribution on the described shell, described inner casing with described outside offer the interior louvre that is matrix distribution on the relative face of louvre; The integral position of louvre is in described outer louvre top in described; Described shell offers the dust discharge bottom outlet in the bottom with described inner casing interval.
As preferably, the shared upper bottom surface of described shell and inner casing, a bottom surface, and two relative sides, described outer louvre and interior louvre are opened on their non-shared faces, so, have not only saved material but also be convenient to install.
The utility model also provides a kind of technical scheme to be: this dustproof electric power case comprises shell and inner casing; Offer the outer louvre that is matrix distribution on the described shell, described inner casing with described outside offer the interior louvre that is matrix distribution on the not relative face of louvre; Described shell offers the dust discharge bottom outlet in the bottom with described inner casing interval.
As preferably, the shared upper bottom surface of described shell and inner casing and a bottom surface.
As preferably, described in the integral position of louvre spatially be in above the described outer louvre.
The beneficial effects of the utility model are: the dustproof electric power case that adopts above-mentioned two kinds of schemes, after dust enters outer louvre on the shell, owing to be subjected to stopping of inner casing surface, under action of gravity, will down drop, and discharge shell from the dust discharge bottom outlet of outer casing bottom, therefore, when having guaranteed heat radiation, also have the good dust-proof effect, can make the interior power equipment of case be difficult for aging.
Description of drawings
Fig. 1 is an example structure schematic diagram of this dustproof electric power case.
Fig. 2 is a three-dimensional structure diagram embodiment illustrated in fig. 1.
Fig. 3 is the three-dimensional structure diagram of another embodiment of this dustproof electric power case.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
Embodiment one
In the embodiment one of Fig. 1-shown in Figure 2, this dustproof electric power case comprises the shell 1 of a cuboid and the inner casing 2 of a cuboid; Offer the outer louvre 11 that is matrix distribution on the described shell 1, described inner casing 2 with described outside offer the interior louvre 21 that is matrix distribution on the relative face of louvre 11; The integral position of louvre 21 is in described outer louvre 11 tops in described; Described shell 1 offers dust discharge bottom outlet 12 in the bottom with described inner casing 2 intervals.For economical with materials and be convenient to install, described shell 1 and inner casing 2 shared upper bottom surfaces, a bottom surface, and two relative sides, described outer louvre 11 and interior louvre 21 are opened on their non-shared faces, when making, two faces that described inner casing 2 independently has can directly be welded on the inner surface of described shell 1.
Embodiment two
In embodiment shown in Figure 3 two, this dustproof electric power case comprises the shell 1 of a cuboid and the inner casing 2 of a cuboid; Offer the outer louvre 11 that is matrix distribution on the described shell 1, described inner casing 2 with described outside offer the interior louvre 21 that is matrix distribution on the not relative face of louvre 11; Described shell 1 offers dust discharge bottom outlet 12 in the bottom with described inner casing 2 intervals.
For economical with materials and be convenient to install, described shell 1 and inner casing 2 a shared upper bottom surface and bottom surfaces, during making, the face that described inner casing 2 independently has can be welded on the inner surface of described shell 1.
For further dustproof, the integral position of described interior louvre 21 spatially is in described outer louvre 11 tops.
In two above-mentioned embodiment, after dust enters outer louvre 11 on the shell 1, owing to be subjected to stopping of inner casing 2 surfaces, under action of gravity, will down drop, and be difficult to enter in the described interior louvre 11, dust falls behind down, to discharge shell 1 from the dust discharge bottom outlet 12 of shell 1 bottom, therefore, when having guaranteed heat radiation, also have the good dust-proof effect, can make the interior power equipment of case be difficult for aging.
