Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an improvement of a device for attaching a pump to a drainage gate provided at a drainage station, and proposes a device which can be easily attached to / detached from a drainage gate and maintained.

[0002]

2. Description of the Related Art Conventionally, it is well known that a pump is attached to a gate of a drainage station to discharge internal water to the outside. Japanese Utility Model Laid-Open No. 62-44928 and JP-A-3-23313 are examples.

[0003]

However, in the above-mentioned conventional apparatus, the impeller shaft is mounted parallel to the gate, that is, vertically, so that it takes time and effort to mount the impeller, and it is necessary to balance the gate to be moved up and down. I'm making it worse. In particular, since the suction port is opened below the gate (near the water bottom), maintenance such as inspection is difficult.

[0004]

SUMMARY OF THE INVENTION This invention is directed to a solves the problems as described above, the place where its gist thereof in the drainage field, that the drainage pump to the gate provided in the drain channel Gate pons mounted with the blade axis horizontal
Flange In flop, the suction port of the pump in the inner water side to position the driving motor on the suction port side, Rutotomoni in the external water side to position the blade to the site of its discharge opening, at one end
A cylindrical support having
Insert the support into the cylindrical mounting hole provided in the gate,
Abut the support flange against the side wall of the
Fix the support to the gate with the fastening plate on the front
It has a pump attached .

[0005]

The device according to the present invention is constructed as described above. Therefore, in mounting the pump on the gate,
It is sufficient to simply insert and fix the pump in the mounting hole provided in the gate in advance, and it is possible to mount it on the gate in a well-balanced manner.In addition, the pump installed in this way has a suction port and a discharge port opened to the side, It is possible to easily inspect the blades and the drive unit, which are the main parts, and the like. In addition, the pump mounted in this manner has an advantage that when performing drainage work, the pressure is high at the front side of the blades and low at the back thereof, so that the sealing performance of the pump drive unit is also good. Hereinafter, the present invention will be specifically described with reference to the drawings.

You.

Next, FIG. 3 shows an apparatus of the above-described embodiment in which a preliminary drainage port 12 is provided above the pump 3 to overflow the internal water level when the screen 4 is clogged.
It is located higher than the expected maximum internal water level. And
A backflow prevention valve 12a is provided to prevent backflow even if the outside water level rises rapidly. In addition, although illustration is omitted with respect to the above-mentioned clogging of the screen 4, it is needless to say that the screen 4 can be provided with a screen scraper to prevent the clogging.

[0008]

The device according to the present invention is constructed as described above, and since the drainage pump has the blades 9 located on the discharge side, the pressure behind the blades 9 is low, and the drainage pump projects from the motor 8. The sealing of the drive shaft of the blade 9 is also simple. Further, in this invention, since the pump 3 is installed horizontally, the suction port and the discharge port are opened to the side when the gate 2 is pulled up, so that maintenance such as inspection can be easily performed. In addition, since the support in which the pump is fitted is inserted and supported in the mounting hole of the gate, the pump can be easily attached to and detached from the gate, and parts can be easily replaced.
