In addition, the sieve portion 70 is inserted into the fitting hole 63 of the inner housing 60 to be fixed by the bolt (71c), the front plate is formed with a handle (71a) in the front center and bolt holes (71b) at both ends 71 is formed.

In addition, a square frame 72 having a hollow portion 72a formed at the center of the front plate 71 is formed, and at one side of the square frame 72, sieves 73a and 73b having different lattice spacings formed on the hollow frame 73. ) Is composed of a mesh insertion hole 72b to be inserted respectively.

The sieve 73a has a large lattice spacing of the mesh and is fastened to the fitting hole 63 located in the lower portion of the fitting hole 63 of the inner housing 60. The sieve 73b has a tight lattice spacing of the mesh. One is configured by fastening to the remaining fitting hole (63).

Referring to the operation and effects of the present invention configured as described above are as follows.

1 to 6, the drainage device 100 is installed by inserting the inner housing 60 into which the strainer 70 is inserted into the outer housing 50, and then fixing the outer housing 50. It is fixed to the guide plate 23 of the government part 20 using the bolt 51a and the nut 51b.

Thereafter, the vertical fixing plate 21 of the fixing part 20 is inserted into and installed in the installation groove 13 of the pump manhole 10 embedded in the ground.

Next, the lifting portion 30 is installed on the support plate 22 of the fixing portion 20 and the end of the wire rope 32b is connected to the lifting ring 41 of the underwater pump 44.

Then, the steel grating 11 is placed on top of the settled ends 12 and 21a.

If rainwater or sewage is introduced into the pump manhole 10, bulky foreign matters are filtered out by the steel grating 11, and moisture is introduced into the pump and concentrated on the floor by the step 14. You lose.

As such, when rainwater or sewage is collected at the bottom of the pump manhole 10, the manager operates the submersible pump 44.

At this time, the submersible pump 44 is a strong suction force rainwater or sewage collected in the bottom of the pump manhole 10 to the hollow portion 53 of the outer housing 50 and the hollow portion 62 of the inner housing 60. It will enter sequentially.

Next, the foreign matter passing through the filter net (73a) of the filter net part 70 is largely to filter the foreign matter.

Thereafter, secondary particles pass through the strainer 73b of the strainer 70 and prevent particles from entering the inside of the underwater pump 44 by filtering small fine foreign substances, thereby causing clogging or failure of the underwater pump 44. It is discharged to the outside through the drain pipe 43 while suppressing.

Then, when drainage of storm water and sewage is completed, the manager removes the steel grating 11, and then dismantles the bolt (71c) fixing the strainer 70, and the strainer 70 to the inner housing 60 It is possible to simply clean the foreign matter filtered in the strainer (73a, 73b) by removing from.

In addition, in the event of blockage or failure of the submersible pump 44, the steel grating 11 is removed and the flange 42 is separated from the two drain pipes 43 so that the drain pipe 43 located at the upper part is a pipe hole. Push in (13a, 21b).

Thereafter, the manager dismantles the fixing pin 34 of the lifting unit 30 and rotates the handle 33 to lift the submersible pump 44 to the upper part. At this time, the submersible pump 44 is supported by the guide plate 23. It is lifted to prevent breakdown or damage.

Thus, the lifted submersible pump 44 is to be used after the cleaning or repair work reinstalled in the reverse order of lifting.

As described above, the present invention has an effect of improving the structure to reduce the construction cost and shorten the manpower and construction time by modifying the internal structure of the conventionally constructed pump manhole to facilitate the installation of the sieve part and the pump part.

In addition, since the inner housing installed inside the outer housing and the strainer coupled to the inner housing are combined in an integrated structure and installed in the fixed part, the management and cleaning of each component is simplified and easily assembled by the outside of the pump manhole. There is an effect that the structure is improved so that the installation can be simply completed through the insertion action.

In addition, by installing double sieves with different lattice spacings in the lower part of the submersible pump, foreign substances contained in sewage or rainwater discharged to the outside through the submersible pump flow into the submersible pump to prevent blockages. There is an effect that the structure is improved to prevent the increase in repair and maintenance costs.

In the above, the present invention has been illustrated and described with reference to specific preferred embodiments, but the present invention is not limited to the above-described embodiments and is not limited to the spirit of the present invention. Various changes and modifications can be made by those who have
