Description

A dust-proof device, a door using the dust-proof device, and a substation box body

technical field

The utility model relates to a dustproof device, a door using the dustproof device and a substation box body.

Background technique

In order to avoid the temperature rise in the power distribution room due to solar radiation, most box-type substations use double-layer plywood structures and walls with heat-insulating materials. Air building structure, with ventilation channels in the top cover. When the indoor temperature of the box-type substation is normal, natural ventilation is mainly used for heat dissipation. In order to ensure natural ventilation, fixed shutters are generally installed in the wall window frame of the box-type substation, and a filter screen is added behind the fixed shutters.

Chinese patent CN202888646U (announcement date is 2013.04.17) discloses a shell of an American-style substation. The shell is provided with a louver for heat dissipation. The inner surface of the louver is covered with a layer of dust-proof filter. There are no gaps in between. Considering that the substation should have good heat dissipation and ventilation conditions, the mesh of the filter screen should be made larger. The louvers can block part of the dust, but the dust coming in between the blades of the louvers can still enter the substation directly through the meshes of the filter screen. The dust may cause equipment failure and pose a safety hazard.

Contents of the invention

The purpose of this utility model is to provide a dust-proof device that reduces the amount of dust entering the substation without affecting the ventilation and heat dissipation performance of the substation; at the same time, the utility model also provides a door and Substation box.

In order to achieve the above object, a dust-proof device of the present invention adopts the following technical solution: the dust-proof device includes a louver and a dust filter layer arranged inside the louver, and the dust filter layer is spaced apart from the blades of the louver.

It also includes an installation base, and the louvers and the dust filter layer can be detachably connected to the installation base.

The dust filter layer includes a sponge layer.

The dust filter layer also includes a net cover for fixing the sponge layer, and the net cover is detachably connected to the installation base.

The net cover includes a cover body and a fixed net detachably connected with the cover body, and an installation space for installing the sponge layer is formed between the cover body and the fixed net.

The outer side of the blade is turned down, and the inner side is turned up.

The shutter also includes a window frame, and each blade is fixedly connected to the window frame.

A door of the utility model adopts the following technical scheme: the door includes a door body, and the door body is provided with a cooling port, and the dust-proof device described in any one of the above is installed at the cooling port.

A substation box of the utility model adopts the following technical scheme: the substation box includes a box body, the box body is provided with a vent, and the dust-proof device described in any one of the above is installed at the vent.

The beneficial effects of the utility model are: when the dustproof device of the utility model is in use, since the blades of the louver and the dust filter layer are arranged at intervals, a collecting space is formed between the blades and the dust filter layer. After the outside dust enters through the louvers, part of the dust will enter the substation box through the dust filter layer, and the other part of the dust will directly land in the collection space between the blade and the dust filter layer and fall to the bottom, thereby reducing the amount of dust entering the substation. The amount of dust to the inside of the substation box.

Detailed ways

An embodiment of a dustproof device of the present invention, as shown in Fig. 1-2, includes an installation base 1, a louver 2 and a dust filter layer 3 arranged inside the louver 2. The shutter 2 includes a window frame 21 and a plurality of vertically spaced blades 22 integrally arranged on the window frame. The outside of the blade 22 is folded downward and the inside is upwardly folded. Z" shape. Each blade 22 is welded on the window frame 21, the shutter 2 is installed and disassembled as a whole, and the window frame is fixedly connected to the installation base 1 by bolts. There is a space 4 for collecting dust between the dust filter layer 3 and the blades 22 of the shutter 2 . The installation base 1 is an installation substrate in the form of a frame, and the louvers 2 are embedded in the installation base. The circumferential direction of the window frame is provided with a flanging 23 which stops against the outside of the installation base, and the flanging is provided with bolt holes.

The dust filter layer 3 includes a sponge layer 32 and a mesh cover for fixing the sponge layer 32 . The net cover includes a cover body 34 and a fixed net 31 connected to the cover body 34 by bolts, and an installation space for installing the sponge layer 32 is formed between the cover body 34 and the fixed net 31 .
