Abstract
The utility model discloses a kind of dust guard and use door and the transformer station box of this dust guard, this dust guard comprises shutter and is located at the filtering dust layer inside shutter, and the spacing with blades of described filtering dust layer and shutter is arranged.The utility model dust guard in use, owing to being that interval is arranged between the blade of shutter and filtering dust layer, forms a collection space between blade and filtering dust layer.After extraneous dust enters from shutter, a part of dust directly to drop in the collection space between blade and filtering dust layer and to fall within bottom, thus can reduce the amount of dust entering into transformer station box inside.
Description
Technical field
The utility model relates to a kind of dust guard and uses door and the transformer station box of this dust guard.
Background technology
Most of box-type substation raises in order to avoid making temperature in power distribution room because of solar radiation, all adopt Double-layer clamp plate structure and be added with the body of wall of heat-barrier material, the top cover of box-type substation adopts the clerestory structure of band air cushion or heat-barrier material, is provided with air duct in top cover.When box-type substation indoor temperature is normal, mainly dispel the heat by natural draft.In order to ensure natural draft, in the body of wall window frame of box-type substation, be generally provided with fixed type blined window, and on rear side of fixed type blined window, set up a screen pack.
The Chinese patent CN202888646U(day for announcing is 2013.04.17) disclose a kind of housing of American transformer substation, this housing is provided with the shutter of heat radiation, the inner surface of shutter is coated with the dust-proof filter screen of one deck, very close to each other between the blade of shutter and filter screen.Consider that transformer station will have good heat dissipation ventilation condition, the mesh of filter screen is done larger.Shutter can stop a part of dust, but still directly can enter transformer station inside by the mesh of filter screen from dust of coming between the blade of shutter, and dust may cause equipment fault, there is potential safety hazard.
Summary of the invention
The purpose of this utility model be to provide a kind of under the prerequisite of ventilation and heat performance not affecting transformer station, be lowered into the dust guard of the amount of dust of transformer station inside; The utility model also provides a kind of door and the transformer station box that use this dust guard simultaneously.
To achieve these goals, a kind of dust guard of the utility model adopts following technical scheme: this dust guard comprises shutter and is located at the filtering dust layer inside shutter, and the spacing with blades of described filtering dust layer and shutter is arranged.
Also comprise installation matrix, described shutter, the equal releasable connection of filtering dust layer are on installation matrix.
Described filtering dust layer comprises spongy layer.
Described filtering dust layer also comprises the guard for fixing described spongy layer, and described guard releasable connection is on described installation matrix.
Described guard comprises cover body and the fixed network with cover body releasable connection, forms the installing space for installing described spongy layer between described cover body and described fixed network.
Described blade outboard turns down downwards, inner side upwards turns down.
Described shutter also comprises window frame, and each described blade is fixedly connected with described window frame.
A kind of door of the utility model adopts following technical scheme: this door comprises a body, and door body is provided with thermovent, and described thermovent place is provided with the dust guard described in above-mentioned any one.
A kind of transformer station box of the utility model adopts following technical scheme: this transformer station box comprises box-like body, and box-like body is provided with ventilating opening, and described ventilating opening place is provided with the dust guard described in above-mentioned any one.
The beneficial effects of the utility model are: the utility model dust guard in use, owing to being that interval is arranged between the blade of shutter and filtering dust layer, forms a collection space between blade and filtering dust layer.After extraneous dust enters from shutter, part dust can enter into transformer station box inside by filtering dust layer, another dust directly to drop in the collection space between blade and filtering dust layer and to fall within bottom, thus can reduce the amount of dust entering into transformer station box inside.
Accompanying drawing explanation
Fig. 1 is the front view of the embodiment of a kind of dust guard of the utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
Embodiment
The embodiment of a kind of dust guard of the utility model, as shown in Figure 1-2: comprise the filtering dust layer 3 installed matrix 1, shutter 2 and be located at inside shutter 2.Shutter 2 comprises window frame 21 and is wholely set the multiple upper and lower spaced blade 22 on window frame, turns down, inner side upwards turns down, 120 degree of dog legs inside and outside blade 22 under blade 22 lateral, in " Z " font under toppling over.Each blade 22 is welded on window frame 21, and shutter 2 carries out installing, dismantling as a whole, and window frame is bolted to connection on installation matrix 1.There is between the blade 22 of filtering dust layer 3 and shutter 2 interval 4 for collecting dust.Installation matrix 1 is the installation base plate in frame form, and shutter 2 is inlaid in be installed in matrix.Window frame circumference has and the flange 23 installing backstop outside matrix, and flange is provided with bolt hole.
Filtering dust layer 3 comprises spongy layer 32 and the guard for fixing described spongy layer 32.Guard comprises cover body 34 and is bolted the fixed network 31 on cover body 34, forms the installing space for installing described spongy layer 32 between cover body 34 and described fixed network 31.Cover body 34 is provided with in the side away from spongy layer for gear that matrix block coordinates is installed along 36, after cover body 34 setting-in enters to install matrix, cover body 34 is fixed on installation matrix by bolt 35.The middle part of cover body is also provided with reinforcement 33, to ensure the intensity of cover body.Cover body 34 and fixed network 31 are equipped with louvre, while fixing spongy layer, ensure the ventilation and heat performance of dust guard.
In the present embodiment, spongy layer is arranged on guard, guard releasable connection installation matrix on, be in order to install, convenient disassembly, can be convenient for changing spongy layer, clear up; In other embodiments, also spongy layer can be adhesive on installation matrix inwall; In other embodiments, also can not fixed network be set, spongy layer is directly fixed on cover body; In other embodiments, cover body also can realize releasable connection on installation matrix by screw.
In the present embodiment, blade adopts the version of inside and outside 120 degree of dog legs, can from both sides catch blowing sand inside and outside shutter; Wind is in the process entered from the space between blade, and wind can commutate under the effect of blade, thus avoid in wind with dust linearly directly enter in shutter, dustproof effect is good; In other embodiments, the dog leg angle of blade, may also be other angle, as 110 degree or 130 degree etc.; In other embodiments, the shape of blade also can adopt cross section to be the blade of circular arc or the tabular be obliquely installed.
