Description

[0001] DRAIN PUMP SYSTEM AND DRAIN SYSTEM USING THE SAME [0002]

The present invention relates to a drainage pump system and a drainage system using the same, which can prevent fluid from flowing through a passage formed inside a blade of an impeller even when the impeller is stopped, and preventing impurities from being caught in a blade of an impeller.

A pump is a device that transports fluid by the action of pressure. A drain pump is a device that transports unnecessary water in a specific area to another area. It is divided into a movable drain pump and a fixed drain pump.

The movable drain pump connects the suction pipe to the suction side of the pump and connects the discharge pipe to the discharge side to transfer the water to the suction pipe to the discharge pipe. Although the portable drain pump has the advantage of being temporarily used, it has a drawback that it can not be used immediately when needed.

The fixed drainage pump is installed directly in the pipeline and has the advantage that it can be used immediately when needed.

However, in the fixed drainage pump, the impeller and the drive unit are integrally formed. Therefore, when repairing or maintenance of the drive unit, not only the drive unit but also the impeller must be separated from the pipe, so that the operation is inconvenient and takes a long time.

In order to solve the disadvantages of the fixed drain pump, the impeller and the driving unit are separated from each other, and then the impeller is installed in the pipeline, and the driving unit is developed and used in the fixed drain pump installed outside the pipeline.

However, since the conventional fixed drain pump as described above is installed in such a manner that the blades of the impeller block most of the pipeline through which the fluid flows, it is difficult to discharge water from the pipeline when the impeller is stopped due to failure of the driving unit, .

In addition, there is a disadvantage in that foreign matter is caught in the blade of the impeller, which hinders the discharge of the fluid.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a drainage pump system and a drainage system using the same, which can solve all the problems of the related art as described above.

One end side of the conduit 50 can communicate with a rain water conduit (not shown) or the like where the fluid to be discharged is stored and the other end side is communicated with a discharge source (not shown) side where almost unnecessary fluid is discarded . The predetermined portion of the conduit 50 is cut, and the impeller 110 can be rotatably installed on the portion of the cut conduit 50.

In detail, the rotating member 111 may be formed in a cylindrical shape and may be positioned between the cut channel 50. Thus, the left end side and the right end side of the rotary member 111 can be connected to one side and the other side of the cut channel 50, respectively, and can be installed to be rotatable. A plurality of blades 115 and 117 may be formed on the inner circumferential surface of the rotary member 111 and rotate together with the rotary member 111 when the rotary member 111 rotates. Therefore, when the rotating member 111 rotates, the fluid is discharged to the discharge source by the blades 115 and 117.

The blades 115 and 117 may be radially arranged on the same circumference with respect to the center of the rotary member 111. [ The length L from the inner circumferential surface of the rotary member 111 to the free ends of the blades 115 and 117 facing the center of the rotary member 111 is shorter than the radius R of the inner diameter of the rotary member 111. Then, between the free ends of the blades 115 and 117 at the center of the rotating member 111 is formed as an empty space. That is, since the passages 110a through which fluids pass are formed inside the free ends of the blades 115 and 117 of the impeller 110, even if the impeller 110 is not rotated, have.

A power transmission means for transmitting the rotational driving force of the driving unit 120 to the impeller 111 may be installed outside the impeller 110.

The power transmitting means includes a connecting shaft 131 connected to the rotating shaft 121 of the driving unit 120 and rotated together with the rotating shaft 121, a driving gear 133 provided on the connecting shaft 131, And a ring-shaped driven gear 135 provided on the outer circumferential surface and engaging with the driving gear 133, and the like.

A tubular connecting member 140 may be interposed between the impeller 110 and the conduit 50 to guide the impeller 110 to the conduit 50 firmly. It is a matter of course that the connecting member 140 is interposed between the left end side of the rotary member 111 and one side of the cut line 50 and between the right end side of the rotary member 111 and the other side of the cut line 50.

At this time, the outer circumferential surface of the rotary member 111 can be inserted into the portion 141 having a large inner diameter of the connection member 140, and the outer circumferential surface of the conduit 50 can be inserted into the portion 143 having a small inner diameter .

The diameter of the rotary member 111 is formed larger than the diameter of the conduit 50 when the rotary member 111 is inserted into the portion 141 having a large inner diameter of the connection member 140. [ The effect of widening the passage 110a formed by the blade groups 116 and 118 under the condition that the cross sectional area of the rotating member 111 through which the fluid passes becomes wider and the sizes of the blades 115 and 117 are the same .

A sealing member (not shown) may be interposed between the conduit 50 and the connecting member 140 and between the rotating member 111 and the connecting member 140. A bearing (not shown) may be interposed between the rotating member 111 and the connecting member 140 to allow the rotating member 111 to rotate smoothly.
