Abstract

PURPOSE:To remove impurities in flowing water from both directions in such a state that the strength of a flowing water pipe is held. CONSTITUTION:The impurities T in a flowing water pipe 1 flowing from one direction are sedimented in an enclosure case 2 through the through hole 14 formed in the flowing water pipe 14 and the sedimented impurities T can be discharged to the atmosphere by opening a partition cock 11. Since the through hole 14 has a diameter smaller than the inner diameter of the flowing water pipe 1, the flowing water pipe 1 is not perfectly cut and the strength thereof is held. Even when flowing water is generated from either one of both directions, impurities T can be sedimented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a contaminant removing device for removing contaminants contained in flowing water flowing through a flowing pipe.

[0002]

2. Description of the Related Art Generally, in running water pipes, for example, ductile cast iron pipes, mortar lining is applied to the inner surface of the pipes to prevent rust, and the quality of water supplied to each household is guaranteed.

[0003]

However, in the above-mentioned conventional technique, the branch pipe is taken out from the upstream side of the flowing water pipe, that is, from the main pipe as needed, and therefore, the flowing water pipe is bored, and Cutting work of running water pipe is performed. There was a problem that metal powder was generated in these construction processes, and metal parts were exposed by the drilling and cutting work of the running water pipe, and rust was generated in this part, so these metal powder and rust powder flowed in the running water pipe. .

Most of the drilling and piping work is performed underground, and sand or the like may enter the running water pipe, making it difficult to guarantee water quality.

Therefore, an apparatus and the like provided with a filter member for removing such foreign matters in running water have been developed. However, if this device is used for many years, the filter member will be clogged and the flow of the running water in the running water pipe will be hindered. Therefore, it is necessary to regularly replace the filter member. This replacement work must be performed by once stopping the running water in the running water pipe and disassembling the device, which is very troublesome.

Further, since the device equipped with this filter member is fitted in the middle of the flowing water pipe, the flowing water pipe is cut and the strength of the flowing water pipe becomes weak. Furthermore, water is constantly supplied in one direction at the mains of water pipes, but backflow occurs in the branch pipes that branch in a mesh pattern depending on the usage and supply conditions of the water, and in the running water pipes such as branch pipes, both Flow may occur in the opposite direction. Therefore, if only the filter member is installed in the running water pipe, the contaminants that have been captured and accumulated by the filter member will flow away from the filter member at the same time as the reverse flow, and the function of the filter will not be fulfilled.

The present invention has been made by paying attention to such a problem, and it is possible to remove the contaminants in the running water from both directions while maintaining the strength of the running water pipe. An object is to provide an object removing device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below. Reference numeral 1 is a water pipe as a running water pipe. It is installed in a sealed state. This surrounding case is substantially cylindrical in the vertical direction, and a predetermined space S is provided between the bottom surface of the surrounding case 2 and the water pipe 1. An opening / closing case 3 is attached to the upper part of the surrounding case 2, and a work case 4 is attached to the upper part of the opening / closing case 3. In addition,
A mechanism having a predetermined function is appropriately attached to the upper portion of the work case 4.

The opening / closing case 3 is provided with a sluice valve 5 for partitioning the enclosure case 2 and the work case 4. A rod 6 is attached to the sluice valve 5, and by operating the rod 6, the sluice valve 5 can be used for connecting and disconnecting the surrounding case 2 and the work case 4. Reference numeral 7 denotes a housing that is housed when the sluice valve 5 is withdrawn from the open / close case 3, and is integrally attached to the peripheral surface of the open / close case 3.

Reference numeral 8 is a drill as a piercing means for moving up and down in the enclosure case 2, the opening / closing case 3 and the work case 4 to pierce the water pipe 1, the outer diameter of which is smaller than the inner diameter of the water pipe 1. In addition, a rotary shaft 9 rotated by a motor or the like is provided above the rotary shaft 9. A hole 10 is provided on the bottom surface of the surrounding case 2, and the hole 10
A discharge pipe 12 provided with a partition plug 11 that is an opening / closing valve that can be opened and closed is extended downward.

As described above, in order to perform the work of attaching the foreign matter removing device 13 to the water pipe 1 after the case and each member are sequentially installed and fixed in the water pipe 1 in a water-sealed state, as shown in FIGS.
As shown in FIG. 3, the rod 6 is operated to open the sluice valve 5 so that the surrounding case 2 and the working case 4 communicate with each other. Then, while appropriately rotating the rotary shaft 9 with a driving device (not shown),
The drill 8 is lowered, the water pipe 1 is pierced, and the through hole 14 is formed.
To provide.

Next, when the drill 8 completely penetrates the water pipe 1, the cut piece of the through hole 14 of the water pipe 1 is housed in the drill 8 and the drill 8 is raised. After that, the rod 6 is operated to close the sluice valve 5, and the communication between the surrounding case 2 and the work case 4 is cut off (FIG. 1).

Then, as shown in FIG.
Is separated from the open / close case 3, and the drill 8 is attached to the work case 4
Then, the holding portion 16 of the inner lid 15 and the fixing portion formed on the rotating shaft 9 (or another lifting shaft) are joined together, and the working case 4 is attached to the opening / closing case 3 again, and the rod 6 is removed. The sluice valve 5 is opened by an operation to connect the surrounding case 2 and the work case 4 with each other. Then, this time, the rotary shaft 9 is operated as a press-fitting means to lower the inner lid 15, press it into a predetermined position on the upper inner surface of the surrounding case 2, and then raise the rotary shaft 9 so that the holding portion 16 and the rotary shaft 9 are separated from each other. Remove the bond.

Finally, as shown in FIG. 3, the open / close case 3 and the work case 4 are removed and the lid member 17 is attached, whereby the attachment of the contaminant removing device 13 to the water pipe 1 is completed. Therefore, it is possible to install the contaminant removing device 13 without stopping the water supply in the water pipe 1 without stopping the water supply.

In the foreign matter removing device 13 of the water pipe 1 constructed as described above, since the enclosing case 2 has a wider passage area than the water pipe 1, the water pipe line is substantially located at the position of the through hole 14. Is enlarged and the flow velocity drops rapidly in this enlarged area.
Therefore, most of the impurities T contained in the running water flowing downward in the water pipe 1 sink to the space S when they reach the through hole 14 due to their own weight and a decrease in flow velocity. .

The impurities T accumulated by a predetermined amount with the passage of time can be discharged to the outside through the discharge pipe 12 as shown in FIG. 3 by opening the partition plug 11 of the discharge pipe 12. Further, in this case, it is possible to sink the contaminants regardless of whether bidirectional running water is generated.

Further, as shown in FIG. 4, since the outer diameter of the through hole 14 is smaller than the inner diameter of the water pipe 1, there is an advantage that the water pipe 1 is not cut and the strength can be maintained. . Further, as shown in FIG. 3, a part of the water enters the space S, and some eddy current D is generated. Therefore, this swirl D
Has a force to wind up the once settled contaminant T into the water pipe 1 again, but as described above, since the through hole 14 is small, the outflow of the contaminant is blocked by the bottom wall of the water pipe 1.

FIG. 5 shows the details of the foreign matter removing device 13 of the second embodiment of the present invention. This foreign matter removing device 13 is the same as the foreign matter removing device 13 of the above-described embodiment of the present invention. Further, an enclosure case 2 that surrounds the water pipe 1 from above and below, an opening / closing case 3 on the upper part thereof, and a working case 4 on the upper part of the opening / closing case 3, are attached on the upper part of the working case 4. A mechanism having a predetermined function is attached as appropriate, but the connecting portion between the opening / closing case 3 and the work case 4, the rotary shaft 9 above the work case 4, and the attachment position of the mechanism are different.

FIG. 6 shows details of the connecting portion between the open / close case 3 and the work case 4. Reference numerals 18 and 18 'denote recesses formed in the flange portion of the opening / closing case 3 so as to face each other by 180 degrees, and projecting pieces 19 and 19' formed on the flange portion of the working case 4 when connected to the working case 4. Can be fitted.

The rotary shaft 9 having the drill 8 extends through a position slightly offset from the center of the upper plate of the work case 4 in the outward direction. In addition, the protruding pieces 19 and 19 ′ are the recesses 1
When the work case 4 is connected so as to be fitted into the pipes 8 and 18 ', the drill 8 is installed so that the center position of the drill 8 is on the center line of the water pipe 1.

Next, when the two through holes 14 and 14 'are formed in the water pipe 1 in the surrounding case 2, first, the working case 4 is attached to the opening / closing case 3, as shown in FIG.
The gate valve 5 is opened. Then, the drill 8 is lowered to form the through hole 14, and then the drill 8 is raised to close the gate valve 5.

Then, as shown in FIG. 6, the work case 4
Is once removed from the open / close case 3, and the work case 4 is rotated 180 degrees from the position so that the protruding piece 19 engages with the recess 18 ′ and the protruding piece 19 ′ engages with the recess 18, and is connected to the open / close case 3. . As a result, the drill 8 has the through hole 14
In addition to the above, another through hole 14 'is set at a position to be bored.

From that state, the partition plate 5 is opened again, the drill 8 is lowered, and the through hole 14 'is drilled, after which the drill 8 is drilled.
, And close the sluice valve. As in the above-described embodiment of the present invention, the work process thereafter is performed by replacing the drill 8 with the inner lid 15, press-fitting it into the surrounding case 2, removing the open / close case 3 and working case 4, and attaching the lid member 17. The attachment of the foreign matter removing device 13 is completed (FIG. 8). In this case, since the contaminant T repeats the sinking action at two places in the water pipe 1, the removal of the contaminant is further promoted.

Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration is not limited to the embodiments, and even if there are changes and additions within the scope not departing from the gist of the present invention. Included in the invention.

For example, although one or two through holes 14 are formed, three or more through holes 14 having a smaller diameter may be formed. Although the through hole 14 is a circular hole formed by a drill, it is not limited to this and may be a horizontally long hole or a vertically long hole.

[0029]

With the above-described structure of the present invention, the foreign matter in the water flow pipe flowing from one direction sinks into the enclosure case through the through hole formed in the water flow pipe, and the on-off valve is opened. , This sinking contaminant can be discharged into the atmosphere. Since this through hole has a diameter smaller than the inner diameter of the water flow pipe, the water flow pipe is not completely cut,
The strength of the running water pipe is maintained, and even if bi-directional running water is generated, contaminants can be submerged.
