[0002]
[Prior art]
Water supply, sewerage, and other water treatment facility pipelines are provided with water control valves at necessary points in order to adjust and control the flow rate of liquid (for example, water) flowing inside the pipeline.
In many cases, these control valves are located underground and are protected by a saddle or valve box.
[0003]
Normally, the lid of the valve box is closed, but mud sand easily flows in due to rain and wind, and the control valve is often buried in the mud sand.
Therefore, when it becomes necessary to operate the control valve by periodic inspection or the like, firstly, the mud and sand accumulated on the control valve in the narrow valve box must be discharged.
Until now, there was no special device or instrument for discharging mud sand in such a narrow valve box, so that workers manually scraped the mud or by using a shovel or scoop. Had been removed.

The storage cylinder 3 captures and stores the accumulated mud sand, the auger body 4 functions to scoop up the accumulated mud sand 103 above or around the water control valve 10, and the valve sensor 5 controls it. It has a function to contact and sense the water valve.
Hereinafter, the structure of the discharging device will be described in more detail.
Here, FIG. 8 is an enlarged view of the inside of the storage cylinder 3 in FIG.
[0022]
The present mud discharge tool A is provided with a handle shaft cylinder 1 for rotating the mud sand from the ground when the mud sand is lifted up, and a storage cylinder 3 is attached to the lower part thereof.
It is preferable that the handle shaft cylinder 1 has a length that reaches at least from the ground surface GL to the water control valve 10.
A grip bar 11 is preferably inserted in the upper end of the handle shaft cylinder 1 so as to be detachable.
[0023]
Therefore, the gripping rod 11 can be attached only when the present discharger A is used, and can be removed when not used, so that the entire discharger can be easily stored and carried. Further, an L-shaped groove 12 including a horizontal groove 12 </ b> B extending in the circumferential direction and a vertical groove 12 </ b> A extending in the axial direction is formed in the upper portion of the handle shaft cylinder 1.
On the other hand, a pull-down shaft 2 that is longer than that and projects to the inside of the storage cylinder 3 is inserted in the handle shaft cylinder 1.
The claw portion 21 at the tip of the pull-down shaft 2 can be fitted into the groove 12 and slide.
[0024]
The pull-down shaft 2 can move in the region where the groove 12 is formed, and can rotate up and down or at a certain angle.
A packing (not shown) for preventing rattling is mounted on the outer periphery of the pull-down shaft 2 to prevent the play when the pull-down shaft 2 moves in the handle shaft cylinder 1.
[0025]
An auger body 4 is attached to the pull-down shaft 2 so as to be covered in the storage cylinder 3, and the auger body 4 includes a cylindrical base 41 and a spiral blade 42 formed on the surface thereof. It becomes more.
The top 4 </ b> A of the auger body 4 is fixed to the pull-down shaft 2, and the top (top top surface) of the auger body 4 is engaged with the top 3 </ b> A (top bottom surface) of the storage cylinder 3.
[0026]
By the way, a slightly narrow thin tube portion 31 is extended above the top of the storage tube 3, and an upper spring S1 is mounted therein.
The upper spring S1 acts to repress the auger body 4 downward.
A clutch cylinder 6 is loosely inserted in the base of the auger body 4, and a middle spring is provided between the top 4A of the auger body 4 and the clutch cylinder 6 so as to compress the clutch cylinder 6 downward. S2 is arranged.
In the initial state, the middle spring S2 is set to have a lower elastic force than a lower spring S3 described later.
[0027]
On the other hand, an upper switching member 7 is attached to the lower end of the pull-down shaft bar 2, and a small-diameter bar 9 extends in a drooping manner on the upper switching member 7.
An upper engaging portion 6 </ b> A that meshes with the upper switching member 7 is formed at the top of the clutch cylinder 6.
On the other hand, a valve sensing element 5 including a shaft portion 51 and an edge blade 52 is passed through the lower bottom of the clutch cylinder 6.
[0028]
A lower switching member 8 is attached to the upper portion of the shaft portion of the valve sensing body 5, and a lower engaging portion 6 </ b> B that meshes with the lower switching member 8 is formed at the bottom of the clutch cylinder 6.
A thin hole 51A having a constant depth is formed in the shaft 51 of the valve sensor 5 along the central axis. The thin rod 9 of the upper switching member 7 described above is formed in the thin hole of the lower switching member 8. 51A is slidably inserted.
The limit of the upward movement distance (escape distance) of the valve sensor 5 is set by the depth of the narrow hole 51A.
[0029]
Also, a lower spring S3 is disposed between the top of the clutch cylinder 6 and the lower switching member 8, and is repelled in a direction away from both.
Therefore, in a normal state, the upper switching member 7 and the lower switching member 8 are in mesh with each other via the clutch cylinder 6, and naturally, the lowering shaft rod 2 and the valve sensing body 5 rotate integrally. be able to.
[0030]
Here, regarding the storage cylinder 3, the storage cylinder 3 has a substantially cylindrical shape and can sufficiently store mud sand.
Moreover, the opening part (opening width L) 31 extended in a longitudinal direction is formed in the side wall of the storage cylinder 3, and the front-end | tip edge part 31 of the side wall is expanded radially outward.
And it is preferable to process the front-end edge part 31 of a side wall into an edge blade so that surrounding mud sand can be easily scraped off.
[0031]
The opening width L is about 3 cm, for example, and the width is appropriately selected depending on the form of the mud sand in order to efficiently introduce the mud sand.
In addition, it is preferable that the lower end edge of the storage cylinder 3 is provided with an edge blade over the entire circumference in order to scrape the lower mud sand.
The structure of the mud sand discharging tool A has been described above. Next, the mud sand discharging operation using the mud sand discharging tool A will be described.
[0032]
1. First, the housing that houses the water control valve 10, that is, the lid 101 of the valve box 100 is opened.
[0033]
2. Next, the pulling shaft 2 of the discharge tool A is grasped and positioned near the center of the valve box 100 (see FIG. 4).
At this time, the claw portion 21 of the pull-down shaft 2 is hooked into the horizontal groove 12B of the handle shaft cylinder 1 (at this time, the upper spring S1 is contracted to store the elastic force).
Therefore, the top 4A of the auger body 4 meshes with the top 3A of the storage cylinder 3 from below, and the auger body 4 and the storage cylinder 3 can move together. In the clutch cylinder 6, the upper switching member 7 and the lower switching member 8 are both engaged with the clutch cylinder 6 by the elastic force of the lower spring S 3, and the valve sensing body 5, the lowering shaft rod 2, Is in a state where it can move together.
Therefore, by rotating the handle shaft cylinder 1, the storage cylinder body 3, the auger body 4, and the valve sensor body 5 can be rotated as a whole.
[0034]
3. Next, when the handle shaft cylinder 1 is pushed and rotated while holding the gripping rod 11, the storage cylinder 3, the auger body 4, and the valve sensing body 5 rotate together.
Therefore, the mud sand around the storage cylinder 3 is scraped off by the front edge 32 of the side wall of the storage cylinder 3 and enters the inside through the opening 31.
At the same time, the mud sand located on the bottom surface of the storage cylinder is filled between the spiral blades 42 of the auger body 4 by the rotation of the auger body 4 (see FIG. 5).
Further, the edge blade 52 of the valve sensor 5 cuts the lower mud sand.
[0035]
4). Furthermore, when the handle shaft cylinder 1 is pressed and rotated, the valve sensing body 5 comes into contact with the water control valve 10.
In this case, the valve sensor 5 is received and moved upwards somewhat by contraction of the middle spring S2.
[0036]
5. Furthermore, when the handle shaft cylinder 1 is pressed and rotated, the valve sensor 5 cannot be moved further downward by the water control valve 10.
Therefore, the valve sensing body 5 receives a certain pressure, the lower spring S3 contracts, and the lower switching member 8 or the upper switching member 7 is released from meshing with the clutch cylinder 6.
As a result, the valve sensor 5 stops rotating in the same manner as the storage cylinder 3 and the auger body 4, and the valve sensor 5 stops rotating.
Here, the rotational force is slightly reduced, and the operator senses that the discharge tool A, specifically, the valve sensor 5 has touched the water control valve 10.
[0037]
6). When the handle shaft cylinder 1 is pressed and rotated, the valve sensor 5 escapes upward and the lower spring S3 contracts, but the small-diameter bar 9 that is an extension of the pull-down shaft 2 is the shaft of the valve sensor 5. By hitting the bottom 51A1 of the narrow hole 51A of the part 51, the hand that holds the handle shaft cylinder 1 feels (feels) a collision with the handle.
At this time, the pressing rotation of the handle shaft cylinder 1 is stopped.
[0038]
7). Next, the discharge tool A is pulled up and removed from the bag (valve box 100) and replaced on the ground surface (see FIG. 7).
[0039]
8). Finally, the claw portion 21 of the lowering shaft rod 2 is removed from the horizontal groove 12B of the handle shaft cylinder 1.
Due to the elastic force of the upper spring S <b> 1, the auger body 4 is lowered and protrudes from the storage cylinder 3.
[0040]
9. When the handle shaft cylinder 1 is slightly tilted and gently pecked on the ground surface GL, the mud sand attached to the periphery of the auger body 4 and the mud sand attached to the inner surface of the storage cylinder body are separated (see FIG. 3).
[0041]
10. If the claw portion 21 of the pull-down shaft 2 is fitted into the horizontal groove 12B of the handle shaft cylinder 1, all operations are completed.
If there is a lot of sediment in the dredging and the valve sensing element 5 does not easily reach the water control valve 10 by the first excavation work, the discharge tool A is lifted from the dredging during excavation, and the mud sand is grounded. It is good to repeat the same operation until it discharges | emits to the upper surface GL, and the water control valve 10 is exposed again using the discharge tool A again.
[0042]
FIG. 9 shows another embodiment of the present invention.
The discharge tool A1 includes a handle shaft cylinder 1 and an auger body 4 fixed to the lower part thereof.
In addition, a valve sensing body 5 having a recess covering the valve is provided at the lower end of the handle shaft cylinder 1.
This discharging tool also rotates while pressing the handle shaft cylinder 1 to capture and fill mud sand between the spiral blades around the auger body, and then discharge the mud sand to the ground surface (A → B).
[0043]
FIG. 10 shows still another embodiment.
This discharge tool A2 has a degree of freedom of vertical movement of the valve sensor 5 in the above-described embodiment due to the elastic pressure.
Therefore, since the valve sensing body 5 presses the water control valve 10 in an elastic manner, the water control valve 10 is protected.
FIG. 11 shows still another embodiment.
The discharge tool A3 includes a storage cylinder 3 having a spiral blade 42A for scraping mud sand on the inner periphery, and a handle shaft cylinder 1 extending from the storage cylinder 3.
Since the central portion of the storage cylinder 3 is hollow, the control valve in the valve box can be released when trapping and filling mud sand.
The discharge tool is also rotated while pressing the handle shaft cylinder 1 to push the storage cylinder 3 into the mud sand, and simultaneously trap and fill the mud sand between the spiral blades 42 </ b> A of the storage cylinder 3. The mud sand is discharged.
Although the present invention has been described above, the present invention can be modified in various ways in addition to the above-described embodiments as long as the purpose is met.
For example, the shapes of the storage cylinder, the auger body, and the valve sensor are not limited to those shown in the drawings, and can be changed as appropriate.
[0044]
【The invention's effect】
According to the present invention, dredged material, that is, mud sand accumulated in the valve box can be efficiently removed.
Further, even when the water control valve is buried at a deep position, it is possible to quickly and reliably scrape the earth and sand from the narrow housing bottom.
