[Detailed description of the device]

[0001]

[Industrial field of application] This plan is to prevent rainwater and sludge on the road from flowing into the sewer from the rainwater outlet during the winter, and to easily discharge the collected dust and sludge. It relates to a groove filter.

[0002]

2. Description of the Related Art Heretofore, in this type, the following has been done. Intake and clean the accumulated dust and sludge with a few workers and a vacuum car. 1 per day
Only a few places could be processed.

[0003]

The problems described in the prior art have the following problems. Garbage and sludge are accumulated in the sewer.

The present application has been made in view of the above problems of the prior art, and an object of the present application is to provide the following. 1. Provide a new method of fixing the net for collecting waste and sludge. 2. Aim to reduce the price of the net part and filter part. 3. Aim to reduce running costs. 4. The filter part can be reused without being thrown away, and the net can be reused until it is damaged. 5. The waste and sludge accumulated on the net can be easily disposed of.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention is as follows. That is, the one of the present application is the step portion 2 in the rainwater groove filter 1.
A drainage filter unit 3 configured to engage and disengage from A;
It is composed of a net part 5 suspended from the draining filter part 3 via a net fixing part 4, and the draining filter part 3 is made of plastic, a metal material or the like in a square shape in a plane, and slightly lowers toward the center. Draining plate 3A configured to incline toward, a circular opening 3B opened in the central portion of the draining plate, a cylindrical portion 3C detachably hung from the circular opening 3B, and the cylindrical portion 3C. The net fixing portion 4 is composed of a perforated plate 3D stretched at the upper end opening and a screw thread 3C1 engraved on the inner peripheral surface of the tubular portion 3C.
Vertical cylindrical body 4A made of plastic or metal material,
A screw thread 4B that meshes loosely with the screw thread 3C1 is engraved above the outer periphery of the vertical cylindrical body 4A, and the net portion 5 includes a cylindrical body 5A made of a net made of plastic as a material. A lower portion of the cylindrical body 5A is a rainwater groove filter that is configured to be openable and closable by a tightening band 5A1 and is clamped by a screw thread 3C1 and a screw thread 4B that screw the upper portion of the net portion 5 together. In this case, the horizontal protrusions 4C can be provided on the lower portion of the outer periphery of the vertical cylindrical body 4A in four directions. Further, the net portion 5 can be made of non-woven fabric.

EXAMPLES Examples will be described with reference to the drawings. 1
Is the rainwater ditch filter of the present invention. Reference numeral 2 is a known rainwater groove, 2A is a known step portion formed on the outer periphery of the upper end of the rainwater groove, and 2B is a known grating which is detachably stretched by using the step portion 2A. Therefore, the rainwater groove filter 1 is composed of a draining filter portion 3 configured to engage with and disengage from the step portion 2A, and a net portion 5 suspended from the draining filter portion 3 via a net fixing portion 4. There is.

The draining filter section 3 is made of plastic,
Drainage plate 3A made of a metal material or the like and having a rectangular shape in a plan view, and is configured to incline slightly downward toward the center.
And a circular opening 3B opened in the center of this draining plate,
A cylindrical portion 3C that is detachably hung from the circular opening 3B.
And a plate 3D stretched over the upper end opening of the tubular portion 3C,
It is composed of a screw thread 3C1 formed on the inner peripheral surface of the cylindrical portion 3C. 3A1 is a left and right locking edge, and 3A2 is a front and rear folding edge.

The net fixing portion 4 has a vertical cylindrical body 4A made of a plastic or metal material, and a screw thread 4B loosely meshing with a screw thread 3C1 above the outer periphery of the vertical cylindrical body 4A.
Is engraved. Reference numeral 4C is a horizontal protrusion that is provided in a lower portion of the outer periphery of the vertical cylindrical body 4A so as to project in four directions. When the screw thread 3C1 and the screw thread 4B are screwed to each other, the horizontal projecting piece is supported while supporting the horizontal projecting piece.
The so-called co-rotation phenomenon can be prevented.

The net portion 5 has a cylindrical body 5A made of a net made of plastic, and a lower portion of the cylindrical body 5A is tightened by a known tightening band 5A1. The net is designed to withstand a weight of 200 kg. Further, the net portion uses "Nisseki Wallif-trademark" or non-woven fabric.

Therefore, the state of fixing the net portion 5 to the draining filter portion 3 is as follows. That is, the net portion 5 is passed through the net fixing portion 4, the upper portion 5A2 of the net portion 5 is folded outward from the upper end of the net fixing portion 4 to cover the screw thread 4B, and then the screw thread 4B is removed. The thread 3C1 of the draining filter part 3 is screwed. By doing so, the upper portion of the net portion 5 is clamped by both screw threads.

The operation will be described together with the effects.

[0012]

Since the present invention is constructed as described above, it has the following effects. 1. Since the net portion 5 is passed through the net fixing portion 4 so that the screw thread 4B is covered by the upper portion of the net portion 5, the screw thread 4B is screwed into the screw thread 3C1 of the draining filter portion 3. The net portion 5 can be attached easily and surely. Also, it is difficult to come off due to the weight of dust and sludge.

2. If dust, sludge, etc. collect in the net part 5, pull out the net part 5 and tighten the tightening band 5A.
1 is loosened and discharged from the lower end opening of the net portion 5.
After this, tighten with the tightening band 5A1 and set as before. Conventionally, such waste disposal work was carried out by about 10 to 12 people, but by installing the thing of this application, it can be processed by 2 to 3 people. As a result, it is possible to dispose of 40 to 60 places, which was conventionally possible to treat only 10 or more places per day.
In this way, the labor cost can be reduced by reducing the number of processing personnel, and the time required for the disposal processing can be shortened.

3. It is possible to prevent waste and sludge from flowing into the sewer main. 4. As for the initial cost, it is a plastic molded product, so the cost is as low as 5,000 yen per piece, and the durability is 4-6.
It is extremely cheap as a year. 5. The running cost can also be kept extremely low because only the net is replaced.
