Description

[Detailed Description of the Invention] The present invention relates to a pump mounting base that makes it possible to easily install a pump in sewer pump equipment and easily connect the pump and a discharge pipe to each other. This invention relates to a pump mount characterized in that a discharge curved pipe is integrally attached and fixed in advance to a part of an invert installed at the bottom of the pump.

In conventional pump chambers, the pump must be attached and fixed to the guide pipe via guide fittings, etc., and then the discharge curved pipe must be connected to this pump. There were drawbacks such as the time-consuming process of connecting the two.

Furthermore, in the past, the invert shape was determined so that the discharge curved pipe fit inside the recess of the invert, which resulted in a large distance between the pump and the invert wall, which had the disadvantage that sand and foreign matter could accumulate in this distance. .

The present invention is a technology developed in view of these conventional drawbacks, and in particular, a bent discharge pipe that can interconnect the discharge pipe and the pump is installed as a part of the invert installed at the bottom of the pump chamber. The bent discharge pipe is fixed to the bottom of the pump chamber by installing and fixing it in advance, and by installing an invert at the bottom of the pump chamber, and by connecting the pump to this bent discharge pipe, the pump is connected to the bottom of the pump chamber. This relates to a completely new technology that allows it to be fixed to the bottom.

To specifically explain one embodiment of the pump mounting table according to the present invention with reference to the drawings, in FIGS. 1 and 2, 1 is a pump chamber, a bottom plate 2, a straight wall pipe 3,
It is composed of an inclined wall pipe 4, a lid frame 5, a lid 6, etc., and a mortar-shaped invert 7 is attached to the bottom of the pump chamber 1 via a mounting bolt or adhesive (not shown) to the bottom plate 2.
Alternatively, it is attached and fixed to the straight wall pipe 3. A recess 9 for installing a pump 8 is provided on the upper surface of the invert 7, and a part of the upright wall along this recess 9 has an automatic attachment/detachment flange 10 on the pump side, and a recess 9 on the discharge pipe side. A discharge bent pipe 1 having a flange 15 at
1 is buried in advance over almost its entire length.
In the figure, reference numeral 12 denotes a discharge pipe connected and fixed to one end of this discharge curved pipe 11.

In the above embodiment, almost the entire length of the discharge curved pipe 11 was buried in the invert 7, thereby integrally attaching and fixing the discharge curved pipe 11 to the invert 7. As shown in FIG.
By reducing the wall thickness (height) of the invert 7 at the part where the invert 7 is attached, and by providing a mounting leg 13 protruding from the discharge curved pipe 11 and embedding and fixing this mounting leg 13 in the invert 7, the discharge curve can be reduced. Invert tube 11 7
It is also possible to integrally attach and fix it to.

As described above, the pump mounting base of this device has a discharge elbow that can connect the pump and the discharge pipe to each other, which is previously attached and fixed integrally to the invert. Therefore, when installing the pump, the pump can be placed on the upper surface of the invert and connected to the discharge elbow fixed to the invert, thereby easily and stably attaching and fixing the pump to the bottom of the pump chamber, thereby simplifying the structure of the pump chamber and improving workability. Furthermore, because the discharge elbow is embedded in the mortar-shaped invert, the wall of the invert is close to the pump, which makes it easier for sand and foreign objects to be sucked into the pump, and it has many other great effects, such as preventing sand and foreign objects from accumulating in this area.
