Utility model content
The purpose of this utility model is to provide a kind of box power distribution room dust control by ventilation device, can when realizing box power distribution room natural draft, realize dust reduction capability, avoids the equipment fault that caused by too much dust, and assurance equipment is normally worked.
The utility model adopts following technical proposals:
A box power distribution room dust control by ventilation device, comprises the fixed type blined window being arranged in box power distribution room body of wall window frame, and fixed type blined window rear side is provided with screen pack, and the vertical section of described fixed type blined window blade is arc.
Described screen pack rear side is provided with dustproof construction, dustproof construction consists of top dustproof construction and bottom dustproof construction, top dustproof construction comprises the first stringer board and the second stringer board being parallel to each other, the first stringer board and the second stringer board are separately fixed at the first transverse slat both sides, the first stringer board and box power distribution room body of wall are fixed, and the lower surface height of the first transverse slat is not less than window frame upper level; Bottom dustproof construction comprises the 3rd stringer board and the 4th stringer board being parallel to each other, and the 3rd stringer board and the 4th stringer board are separately fixed at the second transverse slat both sides, and the 3rd stringer board and box power distribution room body of wall are fixed, and the upper level of the second transverse slat is not higher than window frame lower surface height.
The height of described the 4th stringer board upper surface is higher than the height of the second stringer board lower surface.
Between described two adjacent fixed type blined window blades, be provided with horizontal dust-proof plate.
Between the lower end of described fixed type blined window blade and the horizontal dust-proof plate upper end adjacent with this fixed type blined window blade lower end, be provided with plastic gauze, between the fixed type blined window blade lower surface that level height is minimum and window frame lower surface, be provided with plastic gauze.
The utility model is by adopting the fixed type blined window blade that vertical section is arc, when air-flow passes through, the dust being mingled with in air-flow will be by the fixed type blined window leaf baffle of arc, and under the effect of gravity along the downward landing of fixed type blined window blade of arc, can avoid too much dust to enter box power distribution room indoor, when realizing box power distribution room natural draft, realize dust reduction capability, avoid the equipment fault that caused by too much dust, assurance equipment is normally worked; The utility model also has additional dustproof construction, horizontal dust-proof plate and plastic gauze, can further improve dust-proof effect, simple in structure, is easy to realize.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises the fixed type blined window being arranged in box power distribution room body of wall 1 window frame 2, fixed type blined window rear side (being positioned at the indoor side of box power distribution room) is provided with screen pack 3, for preventing that toy from entering, plays certain dust-proof effect simultaneously.In the utility model, the vertical section of fixed type blined window blade 4 is arc, air-flow enters into box power distribution room when indoor by fixed type blined window, the dust being mingled with in air-flow will be stopped by the fixed type blined window blade 4 of arc, and under the effect of gravity along the downward landing of fixed type blined window blade 4 of arc, can avoid too much dust to enter box power distribution room indoor.Screen pack 3 rear sides are also provided with dustproof construction, dustproof construction consists of top dustproof construction and bottom dustproof construction, top dustproof construction comprises the first stringer board 5 and the second stringer board 6 being parallel to each other, the first stringer board 5 and the second stringer board 6 are separately fixed at the first transverse slat 7 both sides, the first stringer board 5 is fixing with box power distribution room body of wall 1, and the lower surface height of the first transverse slat 7 is not less than window frame 2 upper level; Bottom dustproof construction comprises the 3rd stringer board 8 and the 4th stringer board 9 being parallel to each other, the 3rd stringer board 8 and the 4th stringer board 9 are separately fixed at the second transverse slat 10 both sides, the 3rd stringer board 8 is fixing with box power distribution room body of wall 1, the upper level of the second transverse slat 10 is not higher than window frame 2 lower surface height, and the height of the 4th stringer board 9 upper surfaces is higher than the height of the second stringer board 6 lower surfaces.Dust in air-flow is by after fixed type blined window, and the second stringer board 6 and the 4th stringer board 9 in dustproof construction can stop the dust in air-flow effectively, avoid dust to cause damage to the indoor equipment of box power distribution room.
