Both sides may be bound in the horizontal direction as well. That is, the flow-type drain pipe 30 may be coupled while being sandwiched between the guide plate 34c and the base plate 64 in the horizontal direction. As such, the flow-type drain pipe 30 is bound to the fixed drain pipe 20 in both vertical and horizontal directions and can be supported at three points. This can improve stability and prevent leakage.

In addition, the present invention may further include a stirring unit 70 for diverting the sewage drained to the submersible pump 10 and ejecting it toward the sediment deposited on the bottom of the manhole (2). When the submersible pump 10 is installed in the middle of the lower side of the manhole 2, the bottom edge of the manhole 2 has a relatively weak drainage pressure of the submersible pump 10, so sediment is easily deposited and solidified. The drained sewage water is diverted to the bottom edge of the manhole (2) so that the sediment deposited on the bottom edge of the manhole (2) can flow toward the submersible pump (10) installed in the middle of the manhole (2). This stirring unit 70 is connected to one side of the fixed drain pipe 20 and is installed at the connection point of the bypass drain pipe for guiding the drained sewage to the bottom edge of the manhole 2, and the bypass drain pipe and the fixed drain pipe 20. It may include a bypass valve 72 for controlling the drain direction.

The filter screen 80 may be connected to a chain such that it can be lifted out of the manhole 2 for maintenance. The filter screen 80 may be formed in the form of a barrel having an internal space in which contaminants can be accumulated. That is, the filter screen 80 in the form of a barrel has an upper surface open to allow the inflow of sewage, and a filter for filtering contaminants while the sewage passes through the side and/or lower side may be installed.

The filter monitoring unit 90 includes a trap 92 and a float sensor.

The trap 92 guides the sewage water between the inlet 2a of the manhole 2 and the filter screen 80, and an internal space in which the sewage water can be stored above a certain level according to the degree of clogging of the filter screen 80 is provided. . For example, the trap 92 may be installed at the lower side of the inlet 2a of the manhole 2, and the upper surface of the trap 92 may be connected to the inlet 2a of the manhole 2 so that sewage can be introduced. A drain hole to which the filter screen 80 is coupled may be formed on the lower side of the trap 92 . At this time, the filter screen 80 may be drawn into the inside of the trap 92 at a predetermined height, and the upper side of the trap 92 may be opened to allow the filter screen 80 to be lifted.

A float member 94 that can float on the water surface in the trap 92 by buoyancy and rises and falls according to the water level in the trap 92, and the float member 94. The sensor rod 96 protrudes a certain length from the upper side of the to the outside of the manhole 2, and it is installed outside the manhole 2 and when the water level in the trap 92 rises above a certain water level, the sensor rod 96 is in contact with the filter It may include a contact sensor terminal 98 for recognizing clogging of the screen 80 .

That is, as the filter screen 80 filters out contaminants, the contaminants gradually clog the filter screen 80, thereby increasing the level of sewage in the trap 92, and the float member 94 and the sensor rod 96 It comes into contact with the contact sensor terminal 98 while ascending and descending. When the sensor bar 96 comes into contact with the contact sensor terminal 98, the degree of clogging of the filter scrim is serious and maintenance is required. Through this, the filter screen 80 can be lifted and maintained at an appropriate time. can

In the manhole-integrated pumping station according to the present invention, a control panel for controlling the submersible pump 10, the water level sensor in the manhole, the float sensor, etc. is installed on one side of the manhole. can be In addition, a unique identification number may be assigned to the control panel of each manhole-integrated pumping station so that a plurality of manhole-integrated pumping stations can be remotely managed together.

When describing in detail the effects of the manhole-integrated pumping station capable of remote control according to an embodiment of the present invention configured as described above, it is as follows.

When the submersible pump 10 is seated, the submersible pump 10 is connected by a chain or the like and descends into the manhole 2 . At this time, the fluid drain pipe 30 is connected to the submersible pump 10 and descends together, and in particular, the joint 34 of the fluid drain pipe 30 guides the guide 40 from the upper side of the connection port 22 of the fixed drain pipe 20. It can be lowered vertically. When the submersible pump 10 is seated inside the manhole 2, the joint 34 of the fluid drain pipe 30 is also connected to the connection port 22 of the fixed drain pipe 20, and at this time, the pipe body 32 of the fluid drain pipe 30 ) pulls the joint 34 of the fluid drain pipe 30 downward, and the joint 34 of the fluid drain pipe 30 is securely connected to the connector 22 of the fixed drain pipe 20 by its own weight. In addition, the joint 34 may be bound to the enter lock 45 to be fixed in position. Accordingly, lifting and disengagement of the joint 34 can be prevented more reliably. In addition, the flow-type drain pipe 30 can be supported by the valve pipe union 36 spanning the upper side of the base plate.

As described above, the submersible pump 10 seated inside the manhole 2 is driven when the water level in the manhole 2 rises to a predetermined predetermined water level. When the submersible pump 10 is driven, the sewage in the manhole 2 is pressurized to the submersible pump 10 and may be drained to the outside along the fluid drain pipe 30 and the fixed drain pipe 20 . In addition, if the sewage drained by temporarily manipulating the bypass valve 72 is diverted to the bypass pipe 74, the sewage may be ejected to the bottom edge of the manhole 2 through the bypass pipe 74, and The sediment deposited on the bottom edge of the manhole (2) by the hydraulic pressure of the ejected sewage is stirred before being solidified and can be smoothly sucked and discharged by the submersible pump (10).

In addition, if the filter screen 80 is left in a clogged state, the inflow of sewage water is blocked and the water level in the manhole 2 is maintained at a low state, so that the stop time of the manual pump 10 is lengthened, while the sediment is more firmly deposited and solidified. . However, since the clogging of the filter screen 80 can be checked directly through the float sensor, the filter screen 80 can be maintained at an appropriate time, and thus the solidification of the sediment can be prevented. Since the operation and load of the submersible pump 10 can be prevented, the submersible pump 10 can be operated more efficiently.
