[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glove bag for preventing the spread of radioactive contamination, which is used in the work of disassembling and inspecting equipment contaminated by radioactivity in a nuclear facility or the like.

[0002]

2. Description of the Related Art There have been various types of glove bags for preventing diffusion of radioactive contamination, which are used in maintenance and inspection of equipment contaminated by radioactive rays.

For example, in the one disclosed in Japanese Utility Model Laid-Open No. 60-53098, a frame which is foldably connected to a bottom plate is entirely covered with a transparent and soft sheet, and the sheet is connected to an exhaust duct. It is a glove box that has a connection port, a plurality of arms removed, and a connection surface for entering and exiting equipment to be inspected.

However, such a glove box can be applied to equipment, parts, etc. that can be stored in the box when it is installed as equipment in advance. Not applicable to disassembly and inspection of equipment.

On the other hand, as an example of a glove bag used in a narrow place or a place where the scaffolding is poor, there is an actual fair 1-10.
There is a device disclosed in Japanese Patent No. 639. This invention is characterized in that the bag is configured to be divided into upper and lower parts, and each of the divided parts has an independent closed structure, so that the equipment for inspection and other work can be completely covered. Although it is effective in preventing the diffusion of radioactivity, on the other hand, the present invention has no framework and cannot maintain a constant shape, so that a working space in the bag cannot be secured and there is a problem in workability.

Further, as a method of securing a working space in the bag, there is a case where the periphery of the bag is hung, but this may hinder the work, and since it cannot be applied unless the hanging point is near, the applicable range is naturally. It will be limited.

[0007]

SUMMARY OF THE INVENTION The present invention solves the above problems and enables a simple mechanism to perform work in a bag even in a narrow place or a place with poor scaffolding.
Moreover, the safety of the worker can be ensured.

[0008]

That is, according to the present invention, for example, a rod-shaped or tubular flexible member made of a plastic resin such as polyethylene is assembled into a cubic body, a rectangular parallelepiped body, a columnar body, or the like to form a frame body. , Made of soft material,
In addition, it is characterized in that it is formed in the same shape as the frame body and is housed inside a transparent bag having a glove on the side surface.

The present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing the structure of the present invention, and FIGS. 2 and 3 are explanatory views showing an example of the usage state of the present invention.

1 to 3, reference numeral 1 denotes a frame body made of a flexible member, for example, by welding or inserting a polyethylene round bar having a diameter of 5 to 10 mm into a three-way joint. Assemble a cube, rectangular parallelepiped, cylinder, etc. into an appropriate shape according to the usage conditions. Reference numeral 2 is a bag made of a transparent film, and an appropriate number of gloves 3 are provided on the side surface of the bag to insert a hand during work. 4 is a filter. In FIG. 2 and 3, 5 is an opening, 6 is a device to be disassembled and inspected, and 7 is an obstacle existing in the work place.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION To use the bag of the present invention, as shown in FIG. 1, first, as described above, a frame made of a flexible member made of a plastic resin round bar or tube is used as a material. The body 1 is assembled into a cubic shape, a rectangular parallelepiped shape, a cylindrical shape, or any other suitable shape according to the use condition by means such as welding or insertion into a three-way joint. Next, the frame 1
Is made of a transparent film formed in the same shape as that of the bag, and is housed in a bag 2 having an appropriate number of gloves 3 on its side surface. The frame 1 and the bag 2 are connected by welding,
Any means such as hanging and covering can be adopted.

Therefore, in order to use this, for example, as shown in FIG.
As shown in Fig. 3, the device 6 to be disassembled and inspected is installed in the opening 5
Cover with a tape and seal it. Thereafter, a hand is inserted into the glove 3 to perform a predetermined work. At this time, in the present invention, since the frame 1 has flexibility,
When the bag 2 comes into contact with an obstacle 7 existing in the vicinity of the device 6, the frame 1 can be deformed to avoid the obstacle 7, and a space necessary for work can be secured in the bag 2. Since it can be done, it does not hinder the work.

Further, the bag of the present invention is extremely effective because it deforms according to the work form.

FIG. 3 shows an example thereof, and when a force is applied to the frame body 1 from the outside, the frame body 1 is deformed into an arbitrary shape. For example, when it is necessary to change the shape of the bag 2 due to the reason that the working place gradually becomes deeper, when a force is applied from the outside, the portion to which an external force is applied is deformed to the inside, and accordingly the portion on the opposite side is deformed. The surface also deforms inward. On the other hand, the surface perpendicular to the surface to which the pressure is applied bulges outward.

It is possible to prevent the contamination of the inside from diffusing to the outside by passing the air in and out of the bag 2 due to the deformation through the filter 4. In any case, after the work is completed, the original shape is restored.

The frame 1 can be selected from round bars, round tubes, square bars, square tubes and other arbitrary shapes.

[0018]

As described above, according to the present invention, the shape of the bag can be changed and the working space can be secured inside by deforming the frame as needed. Therefore, even in a narrow working place. It is possible to work without any problems and is extremely effective.
