Abstract

PURPOSE:To realize easy and reliable operation and to shorten the work time by enclosing a resin powder having high water absorbing power in a water permeable bag and coupling a linear body, to be pulled into an electrical piping, directly or indirectly to one end of the bag. CONSTITUTION:A water eliminator for electrical piping 8 comprises a resin powder 2 having high water absorbing power encapsulated in a water permeable bag 1, which is normally flat but expands into gas cylinder shape or cylindrical shape, and a linear body 5 coupled to one end of the bag 1. The water eliminator 8 is pulled in a piping 4 while sliding thereon. When the bag body 1 contacts with water 12 stored at a curved part of the piping 4, the resin powder 2 in the bag body 1 absorbs the water to expand into basket shape. If thus pulled out bag body 1 has outer diameter approximately same as the inner diameter of the piping 4 it means that the water still remains in the piping 4, whereas when the outer diameter of the bag body 1 is considerably smaller than the inner diameter of the piping 4 it means that the water is eliminated sufficiently.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a water removal tool for electrical piping used to remove water accumulated in electrical piping.

[Prior art and problems to be solved by the invention] Conventionally, water accumulated in electrical piping has been removed by blowing it out with air. As a result, there were problems in that the equipment was severely damaged, the time required was long, and the surrounding area was contaminated.

Furthermore, even when a cleaning tool such as a cloth or sponge was passed through the pipe, the water absorption power was weak and the accumulated water could not be removed sufficiently.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide a water removal tool for electric piping that is easy and reliable to operate and can shorten the time required for the work.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention includes a water-permeable bag body filled with super absorbent resin powder, and a water-permeable bag body containing a superabsorbent resin powder at one end of the bag body for drawing into electrical piping. The filament bodies were connected directly or indirectly.Also, super absorbent resin powder was sealed in a water-permeable bag, the bag was covered with a sliding wear protection member, and electrical piping was connected to one end of the protection member. The striated body for retraction into the interior is connected directly or indirectly. Either connection can be made by connecting one end of the striated body directly to the bag body or the protective member, or by connecting it to the bag body or the connecting member. They may be connected indirectly via a ring or a chain.

[For production]

All you have to do is pull the filament and slide the water-permeable bag through the electrical piping.The superabsorbent resin powder sealed in the bag instantly absorbs the accumulated water in the piping and expands. , accumulated water is retained within the bag and removed along with the bag. Furthermore, if the bag body is coated with a sliding wear protection member, the bag body will not be worn out by sliding.

〔Example〕

Hereinafter, the present invention will be explained based on illustrated embodiments.

FIG. 1 shows an embodiment of the water removal tool 8 for electrical piping according to the present invention. The water removal tool 8 for electrical piping is flat when not in use, and has a gas cylinder-like or cylindrical shape when expanded as described below. Super water-absorbent resin powder 2 is sealed in a water-permeable bag body 1, and a striated body 5 is connected to one end 3 of the cough bag body 1, and a locking hole is provided at the tip of the striated body 5. A crimp fitting 9 is crimped. The super absorbent resin powder 2... is a sodium polyacrylate crosslinked product (for example, Aqua Keep 103H or Aqua Keep 10SH-P).
, manufactured by Sumitomo Seika Co., Ltd.) is used. The resin FA2・
... is 500 to 1000 times its own weight of water.
Water expandable. The water-permeable bag 1 is made of a material such as cloth that does not allow the resin powder 2 to pass through but allows moisture to pass through, and has a circular cross-sectional shape when inflated (see Figure 10). The outer diameter is set to be equal to or slightly smaller than the inner diameter of the electrical piping 4 to be used. In the striatum 5,
A wire, string, or the like is used and is connected to one end 3 of the bag 1 by caulking.

In FIG. 2, striated bodies 5.
Fig. 3 shows a water removal tool 8 in which a plurality of bags 1... are connected in series by filament bodies 5..., and Fig. 4 shows a water removal tool 8 in which a plurality of bags 1... , shows a water removal tool 8 in which a plurality of bags 1... are connected in parallel by filament bodies 5....

These water removal tools 8 are used when there is a large amount of accumulated water 12 in the electric pipe 4 or when the pipe 4 has a large diameter.

The water removal tool 8 shown in FIG. 5 is flat when not in use, but has a cylindrical bag body 1 when inflated, and a filament body 5 passes through the bag body 1, and a locking member 10. At 10, the striatum 5
The bag body 1 is fixed to.

In the embodiments shown in FIGS. 1 to 4 described above, a ring is fixed to at least one end 3 of the bag 1 by caulking or the like, or a chain is fixed, and the filament 5 is attached to this. may be concatenated.

That is, the filament body 5 can be freely connected to the bag body 1 either directly or indirectly.

Another embodiment of the water removal tool 8 for electric piping is shown in FIG.
When inflated, superabsorbent resin powder 2 is sealed in a gas cylinder-shaped or cylindrical water-permeable bag 1, and the bag 1 is covered with a mesh bag-shaped sliding wear protection member 6 to protect the bag. A filament 5 is connected to one end 7 of the member 6, and a crimp fitting 9 with a locking hole is crimped to the tip of the filament 5. The protection member 6 is
When the water removal tool 8 slides inside the pipe 4, the bag body 1 is prevented from being worn out. The protective member 6 may be a net bag made of plastic or the like, or a bag made of cloth, nonwoven fabric, vinyl, nylon, etc., with a large number of holes 11 formed therethrough, as shown in FIG. In FIG. 8, a plurality of bags 1... are shown in the protection member 6.
At the same time, both sides 477 of the protective member 6 are coated with a filament body 5.
5 shows a water removal tool 8 in which 5 is connected. In FIG. 9, the bag 1 is covered with a cylindrical mesh-like protection member 6, and the protection member 6 is
A water removal tool 8 is shown in which connection members 13 and 13 are attached to both ends 7 and 7 of the water removal tool 8, and a filament 5 is caulked and connected to the connection members 13. In this water removing tool, since the protective member 6 is cylindrical, the bag body 1
can be easily taken in and out of the protective member 6. In this way, the filament 5 can be connected directly or indirectly to the one end 7 of the protection member 6, and a ring or chain can be attached to the one end 7 of the protection member 6. The filament body 5 may be connected to this (indirectly connected).

As shown in the order of N)→(It)→(I[l) in FIG. 10, the water removing tool 8 of the present invention moves while being pulled and sliding inside the pipe 4. The bag 1 is placed in the accumulated water 12 at the curved part of the pipe 4.
When they come into contact with each other, moisture is absorbed by the resin powder 2 in the bag 1, and the resin powder 2 greatly expands inside the bag 1 to become a sol. That is, the water removal tool 8 removes the accumulated water 1 in the pipe 4.
While removing water from the pipe 2, the pipe 4 is slid inside the pipe 4. In particular, although the bag 1 (or the protective member 6) is flat in FIG. It becomes a cylinder and is pulled out.

If the outer diameter of the pulled out bag 1 (or protective member 6) is equal to or slightly smaller than the inner diameter of the pipe 4, the pipe 4 is still
It can be predicted that some water 12 remains inside the pipe, and the water removal work should be carried out again.On the other hand, if the outer diameter is considerably smaller than the inner diameter of the pipe 4, the water inside the pipe 4 cannot be removed. I can see that enough has been done.

In this way, when not in use (initial state shown in Figure 10 (1))
Since the bag 1 (or protective member 6) is in a flat state,
It is possible to determine whether there is a remaining amount of water in the inner part of the pipe 4.

It should be noted that the present invention is not limited to the above-described embodiments, and design changes may be made without departing from the gist of the present invention.

〔Effect of the invention〕

Since the present invention is configured as described above, it achieves the remarkable effects described below.

It has a small number of parts, a simple structure, and can be folded compactly, making it convenient to carry. In addition, the operation is simple and reliable.
It is easy to work with, and the time required can be reduced considerably. Furthermore, since it can be manufactured at low cost, it can also be disposable. According to the second aspect, since the sliding wear protection member 6 is coated on the bag body 1, wear and breakage of the bag body 1 can be prevented, and therefore, durability is improved.

Furthermore, once it becomes a sol and absorbs water, it does not drip or flow down outside the piping 4, which is preferable because it does not wet the floor or the like.
