Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dustproof house, for example, a dustproof house that surrounds the equipment to prevent dusting when assembling or disassembling large equipment on site. Is.

[Prior Art] FIG. 2 is a schematic perspective view showing an example of a conventional dustproof house of this type.

In the figure, reference numeral (1) is a house body composed of a side wall (1a) and a ceiling (1b) of an air bag shape (air film structure) in which a large number of air tubes are arranged, and (2) is a ceiling (1b).
The dust-proof house is a transparent vinyl sheet (not shown) that covers the house body (1), the lid part (2), and the end surface of the house body (1). )
It consists of

In the conventional dustproof house as described above, air is sent into the side wall part (1a) and the ceiling part (1b) to raise the house main body (1) as shown in the figure at the site. Then, inside of that, for example, assembling and disassembling of a device such as a gas insulated switchgear.

By the way, when a part of equipment (such as a bushing) is higher than the house body (1) such as a large-sized gas-insulated switchgear, the part of the equipment is installed from the upper part of the house body (1). It is necessary to suspend it. In such a case, the lid part (2) was removed from the ceiling part (1b) by a crane, and a part of the ceiling part (1b) was opened.

[Problems to be Solved by the Invention] In the conventional dustproof house configured as described above, when removing the lid portion (2) from the ceiling portion (1b), the lid portion (2) in an air mat shape is removed by a crane. Since it is necessary to lift the lid, there is a problem that the lid portion (2) is injured by the wind when there is wind.

The present invention has been made to solve the above problems, and to obtain a dustproof house in which the opening can be safely provided in the ceiling of the house body even when the wind is blowing. With the goal.

[Means for Solving the Problems] In a dustproof house according to the present invention, the house body can be divided into a first body and a second body along a surface intersecting the installation surface, and the first and second bodies are also provided. The connection side wall that covers the space between the side walls of the first and second main bodies while leaving the opening of the ceiling part at the time of division is stored in the storage part provided in at least one of the joint parts.

[Operation] In the present invention, the opening is provided in the ceiling portion of the house body by dividing the house body and covering the side walls of the first and second bodies with the connecting side wall.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. First
FIG. 1 is a side view showing a dustproof house according to an embodiment of the present invention.

In the figure, reference numeral (3) is a house body composed of a side wall portion (3a) and a ceiling portion (3b) having an air film structure similar to the conventional one, and the house body (3) is orthogonal to its installation surface (4). It can be divided into first and second bodies (5), (6) along the surface. Further, rollers (7) are provided below the first and second main bodies (5), (6), respectively.

(8) is a divided first and second body (5),
A sheet-shaped connecting side wall made of vinyl or the like covering between the side walls of (6). The connecting side wall (8) is a second side wall when the first and second main bodies (5) and (6) are joined. Storage part (6a) provided at the joint part of the main body (6) with the first main body (5)
Is stored in.

In addition, the dustproof house of this embodiment has a house body (3).
And a vinyl sheet (not shown) that covers the end face of the house body (3).

In the dustproof house configured as described above, the side wall part (3a) and the ceiling part (3b) are used on site as in the conventional case.
By feeding air into the house, the house body (3) is erected. At this time, normally, the first and second main bodies (5) and (6) are joined, and the connection side wall (8) is housed in the housing portion (6a).

On the other hand, when assembling a large-sized gas-insulated switchgear as an object to be protected, such as when assembling a device from above the ceiling part (3b) of the house body (3), the house body (3) is first And a second body (5), (6). Then, the divided side walls are connected and covered by the connection side wall (8). As a result, the opening (3
c) will be provided.

If the opening (3c) is provided by such a method, it is not necessary to lift the lid (2) with a crane as in the conventional case,
You can work safely even in the wind.

In addition, although the sheet-like connection side wall (8) is shown in the above embodiment, for example, an air bag-like connection side wall or a combination of air tubes may be used. It becomes taller and you can work more safely even in windy conditions.

Further, in the above embodiment, the storage portion (6
Although a) is provided, it may be provided on the first main body (5) or on both the first and second main bodies (5) and (6).

Furthermore, the joint portions of the first and second main bodies (5) and (6) may be joined using, for example, a waterproof fastener or a rope.

Furthermore, in the above embodiment, the divided first and second
The entire space between the ceiling portions (3b) of the main bodies (5) and (6) is defined as the opening (3c), but the divided ceiling portions (3b) are partially covered to reduce the opening (3c). You may

In the above embodiment, the first and second bodies (5),
Although the roller (7) is provided on both (6), if the roller (7) can be moved at the time of division, the roller (7) will be the first and second rollers.
May be provided on either one of the main bodies (5) and (6) of
Further, it may not be provided in either of them.

Furthermore, the overall shape of the house body (3) is not limited to the above embodiment.

Furthermore, the protected object is not limited to the gas-insulated switchgear, and may be, for example, a transformer.

Further, in the above embodiment, the house main body (3) was erected by sending air, but other gas may be sent as long as the house main body (3) can be erected.

[Effects of the Invention] As described above, in the dustproof house of the present invention, the house body can be divided into the first and second bodies, and
Since the connection side wall is stored in at least one of the first and second main bodies and the side wall of the first and second main bodies is covered with the connection side wall at the time of division, even when the wind is blowing, The effect that the opening can be safely provided in the ceiling of the house main body is achieved.
