Description

Technical Field

[0001] The present invention relates to a submersible pump having a flange attached to a discharge port cylindrical portion of the submersible pump and a water supply method using this submersible pump.

Background Art

[0002] As shown in Fig. 13A, since the discharge port cylindrical portion 161 of the conventional submersible pump 160 is tapered and narrowed toward the outlet, the attachment work for inserting the hose 110 is easy, but there is a problem that the hose 110 is likely to come off.

[0003] Also, the planar shapes of the existing mounting plates 162 provided with the submersible pump integrated with the existing discharge port cylindrical portion 161 of the submersible pump vary depending on the manufacturer, such as elliptical or polygonal, and the number and arrangement of the bolts for fixing each are also different. Therefore, as shown in Fig. 13B, in order to connect to the hose 110 provided with a general-purpose flange 111 having a circular planar shape and eight bolt holes at equal intervals, the existing discharge member 164 including the existing mounting plate 162 integrated with the existing discharge port cylindrical portion 161 is removed, and a new mounting plate 163 matching the mounting structure for each manufacturer's product and a new discharge port 168 provided with both the general-purpose flange 111 at both ends are produced and replaced. However, the structures of the existing mounting plates 162 provided for each manufacturer's product are diverse, and there is the trouble of making the new mounting plate 163 match the diversity. Also, since there are cases where a hose 110 without a flange at the tip is used at the end of the discharge port cylindrical portion 161 of the existing discharge member 164 as shown in Fig. 13A, it was necessary to frequently replace it, which was troublesome.

Next, the tip of the discharge port cylindrical portion 10 is brought into contact with the tip of the cylindrical inner circumferential member 35 via an elastic sealing member 55a such as a rubber packing. As a result, the cylindrical outer circumferential member 30 is positioned on the outer circumference side of the discharge port cylindrical portion 10, and in this state, the cylindrical outer circumferential member 30 may be fixed to the discharge port cylindrical portion 10 with a fastening band 41 or the like.

[0057] Then, the fastening member 70 is attached between the flange member 20 and the submersible pump body 60. The attachment method is as follows: In the case of the flange member 20 to which the fastening plate member 80 shown in Figure 10 is attached, the two are fastened together by the fastening member 70, which is hooked onto the hook hole 81 of the fastening plate member 80 on the flange member 20 and the hook hole 81 of the fastening plate member 80 fixed by the bolt 62 that fixes the mounting plate 162 installed on the submersible pump, as shown in Figure 10A. Even when using a fixing member 40 in which a ring or hook is formed on the head of the bolt as shown in Figure 7C, the two are fastened together by the fastening member 70, which is hooked onto the ring or hook and the hook hole 81 of the fastening plate member 80 fixed by the bolt 62 that fixes the existing mounting plate 162 installed on the submersible pump as shown in Figure 6. In this way, by tightly connecting the submersible pump body 60 and the flange member 20, the discharge port cylindrical portion 10 and the flange member 20 are strongly pressed together, preventing the possibility of water leakage, and also preventing the flange member 20 from coming off during use of the submersible pump body 60.

[0058] As described above, by fixing the flange member 20 to the discharge port cylindrical portion 10, a versatile flange 111 is attached to the submersible pump body 60, and as shown in Figures 10B and 10C, it can be firmly connected to a water supply hose 110 equipped with a general-purpose flange 111.

[0059] In the above-described embodiment, when attaching the fastening member 70 to the submersible pump body 60, one end of the fastening member 70 was hooked into the hook hole 81 of the fastening plate member 80 attached to the flange member 20 by the fixing member 40, and the other end was hooked into the hook hole 81 of the fastening plate member 80 fixed by the bolt 62 that fixes the existing mounting plate 162 installed on the submersible pump, and the two ends were fastened together with the fastening member 70. However, as shown in Figure 11, the other end may also be hooked into the hole of the strainer 65 of the submersible pump body 60.

[0060] Alternatively, as shown in Figure 12, the fastening member 70 may be hooked onto the connecting hole 22 of the flange 21 of the flange member 20 and the connecting hole 22 of a general-purpose flange provided at the end of the water supply hose 110.

[0061] By using the submersible pump according to each of the embodiments described above to supply water, the possibility of the water supply hose coming off is reduced, and stable water supply can be achieved.

[0062] It should be noted that the present invention is not limited in any way to the embodiments described above, and can be implemented in various forms as long as they fall within the technical scope of the present invention. [Industrial applicability]

[0063] As shown in the above-described embodiment, it can be used as a component for connecting a submersible pump and a connector having a general-purpose flange. [Explanation of Symbols]
