Abstract

The utility model relates to a louver door (window) which is characterized in that the inside of a window frame is provided with 2 to 6 layers of window sheets, and the opening directions of window blades of the odd layers of window sheets and the even layers of window sheets are in the manual staggered arrangement; a pore gap between each window blade and each window sheet is 1 to 5 mm. The utility model has the advantages that the louver door (window) solves the defects that the dust-proof effect of a tradition louver door (window) is poor, and small animals can easily enter rooms. The louver door (window) can be used for transformer rooms and some distribution rooms of transformer substations and various warehouses and other buildings with the requirements that the dust-proof effect is good, small animals are prevented from entering rooms, and the effects of ventilation and heat radiation are good.

Description

Louver door and window

The utility model relates to a kind of blind door and window, especially for the blind door and window that prevents dust, anti-toy enters.

Shutter, shutter door and wire gauze cellular type door and window are continued to use for many years as means of ventilation in the transformer room of the high voltage substation in known technology and KV distribution chambers 10 always.The draft type of this door and window is that air-flow is circulated frank and outspokenly, easily a large amount of dusts in outside is brought into indoorly with the inflow of air-flow, causes on the electric fixtures laying dust serious, and dielectric level descends, particularly when having moisture to invade more very.Be easy to cause the discharge of electric fixtures phase fault, cause large-area power-cuts.Because the mesh aperture of mesh-type window is 10～15 millimeters, kerf spacing is 10～15 millimeters between the window leaf of shutter, and toys such as snake and mouse are easy in the inlet chamber, climbs to cause short circuit dischange on the electric fixtures equally again.Seriously jeopardize the safe operation of power supply unit.In addition, the work that also can thereupon bring the operation staff to clean laying dust.Be that workload is big like this, unhygienic, and also danger is also very big.When blowing again, again can very fast laying dust.

The purpose of this utility model is a kind of good dustproof effect to be provided, to prevent the blind door and window in the toy inlet chamber for the deficiency that overcomes known technology.

The purpose of this utility model is achieved in that

2～6 layers of luffer boards are housed in the window frame of the present utility model, wherein the opening direction of the window leaf of 1,3,5 of odd number layer of luffer boards is arrangement interlaced with each other with the opening direction of the window leaf of 2,4,6 layers of luffer boards of even numbers wherein, and the hole seam is 1～5 mm wide between described window leaf and luffer boards.

There is the overstocked deflector that becomes 30 °～70 ° of inclination angles with ground the 1st～6 layer of luffer boards of the present utility model below, the inclination mode of laying dust deflector is that window is inboard high, and direction is reduced to window downside level gradually outside window, and the support that keeps the luffer boards space is housed in the laying dust deflector left and right sides.

Laying dust deflector upper surface of the present utility model is fixed with the laying dust flow guide bar of warpage.

The advantage that the utlity model has is: compare good dustproof effect with shutter door, window in the known technology.Because the interplanar hole of its window leaf and luffer boards seam is little, institute is in case snake and toy are good by performance.Through testing in the transformer room, the laying dust amount on power supply unit is compared with traditional shutter door, window with shutter door of the present utility model, window, descends nearly 10 times.So both alleviate the workload that the operations staff cleans dust, the insulating properties of having protected equipment, also improved the reliability of power supply.And the heat dissipation ventilation effect of blind door and window of the present utility model might as well.

The utility model has following accompanying drawing:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a laying dust deflector schematic diagram of the present utility model;

Fig. 3 be among Fig. 1 A to the bottom schematic diagram.

Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:

In the window frame 3 of the present utility model 2～6 luffer boards 2 can be housed, present embodiment is selected for use 4 luffer boards is housed.Window leaf 1 all is housed on each luffer boards, and window leaf and the slit between the upper shed of luffer boards plane can be 1～5 mm wide, and present embodiment is elected 4 mm wides as.In addition, the opening direction of the window leaf of the 1st, 3 two-layer luffer boards is served as reasons oblique below obliquely upward, and the opening direction of the window leaf of the 2nd, 4 two-layer luffer boards is that oblique upper is to oblique below.Thereby formed the opening direction arrangement interlaced with each other of the window leaf of the window leaf of the 1st, 3 layer of luffer boards and the 2nd, 4 layer of luffer boards.4 luffer boards all place on the support 4 in addition, in order to the interval of 4 luffer boards of relatively stable maintenance.Below the luffer boards of vertically placing 2, a laying dust deflector 5 that becomes 30 °～70 ° of inclination angles with ground is housed, on the laying dust deflector, is fixed with laying dust flow guide bar 6.Support 4 also is equipped with in both sides at laying dust deflector 5, and air draught is a tortuous repeatedly streamline by the outdoor path that flows to when indoor.As Fig. 1, Fig. 2 and shown in Figure 3, flow into air and indoorly to sink, the dust of falling on the laying dust deflector 5 of inclination can be under the guiding of laying dust flow guide bar 6, by indoor flow to outdoor, shown in arrow among Fig. 3 by luffer boards 2 and window lower end, outside the gap location delivery chamber that laying dust flow guide bar 6 is erected.

In addition, also can from the A of Fig. 1 to, the opening direction of the window leaf of its 1st, 3 layer of luffer boards is, by the right front to the left back, and the opening direction of the window leaf of the 2nd, 4 layer of luffer boards, then be by the left front to the right back, thereby arrangement is arranged in the friendship each other of opening direction that has formed the window leaf of the window leaf of the 1st, 3 layer of luffer boards and the 2nd, 4 layer of luffer boards.

The utility model except that the transformer room that can be applicable to transformer station and some switchgear houses, also can be used for needing to ventilate, dispel the heat, again good dustproof effect, prevent in the storehouse and other building constructions in the various warehouses that toy enters.
