Abstract

(57) [Summary] [Purpose] A portable submersible pump is operated in a stable seated state without changing the shape and dimensions of the conventional pump body by supporting the force applied to the pump body during discharge operation on the gantry. In addition, the power supply cable can be stored in the pump when the portable submersible pump is not in operation. [Structure] The pump body 1 is installed on a pedestal 2 having legs 21 and 21 that are pipes bent into an elliptical shape having a long axis longer than the lateral width of the pump body 1. When the pump main body 1 is operated with the pedestal 2 seated, the legs 21 and 21 support the force applied to the pump main body due to the reaction force of the discharge water and the weight of the drain hose 14. A pipe framework 4 is provided on a gantry 2 so that a drainage hose can be wound and stored.

[Industrial applications]

 The present invention relates to a portable submersible pump which is mainly used when emergency drainage is required at the time of flood or flooding.

[0002]

[Prior Art]

 A conventional portable submersible pump of this type is shown in FIG. This portable submersible pump has a suction port at the bottom of a cylindrical housing 51, the periphery of the suction port is covered with a strainer 52, and a discharge port 53 to which a drain hose 54 is connected is provided on the side of the housing 51. The power supply cable 55 is provided from the top of the housing 51.

Such a portable submersible pump is carried to a place where emergency drainage is required at the time of flooding or flooding, and is operated with its strainer 52 seated.

[0004]

[Problems to be solved by the device]

 However, depending on the place where the strainer 52 is seated, the seated state may become unstable, and if the operation is continued in such an unstable seated state, the pump may tip over or the drain hose may be twisted or bent. There is a possibility that it will occur, and if such a situation occurs, sufficient drainage function will not be exerted.

Therefore, conventionally, it has been attempted to obtain a stable seated state by taking measures such as increasing the diameter of the strainer 52 or forming the strainer 52 into a downward expanding shape. However, they are for obtaining a stable seated state. It couldn't be a sufficient measure.

In addition, in the conventional portable submersible pump, it is inconvenient to dispose of the power feeding cable 55 when it is not in operation such as carrying or storing, and it is difficult to handle the power feeding cable 55.

The present invention has been made in view of the above circumstances, and stabilizes the seated state of the pump without impairing the handleability such as portability and without changing the shape or size of the conventional pump body. At the same time, it is an object of the present invention to provide a portable submersible pump that can easily dispose of a power supply cable.

[0008]

[Means for Solving the Problems]

 The portable submersible pump of the present invention has a suction port and a strainer covering the periphery of the suction port in the lower part, and the strainer in the pump main body to which the power feeding cable is installed is wider and wider than the pump main body. The frame is installed on a gantry made of pipes, and an enclosing frame made up of a plurality of pipes arranged in an annular shape is erected on the gantry so as to surround the pump body.

[0009]

[Action]

 With this configuration, the width of the gantry is longer than the width of the pump body, so that the installation state of the pump body with the gantry seated is stable. Moreover, since the frame of the gantry and the surrounding frame are made of pipes, they are lightweight. In addition, the enclosure helps to wrap and store the power cable.

 FIG. 1 is a schematic perspective view of a portable submersible pump according to an embodiment of the present invention, FIG. 2 is a partially cutaway side view schematically showing a main part thereof, 1 is a pump body, and 2 is a pedestal. The pump body 1 is the same as that described as a conventional example in FIG. 3, and has a suction port 16 at the bottom of a cylindrical housing 11 and is fixed to the housing 11 so as to cover the periphery of the suction port 16. It has a cylindrical strainer 12 provided in the. In addition, a discharge port 13 to which a drain hose 14 is connected is provided on a side portion of the housing 11 in the pump body 1, and a power supply cable 15 is further installed from the top of the housing 11. . The strainer 12 is formed by a large number of columns 12a ... Arranged in a ring shape with a predetermined gap. In the gantry 2, a pair of legs 21 and 21 made by bending a metal pipe into an elliptical shape, and a lateral portion between the upper side portions 22 and 22 of these legs 21 and 21. A pipe frame is formed by the reinforcing rods 24, 24, which are metal pipes that are fixed by being bridged, and are further laid horizontally between the lower side portions 23, 23 of the pair of legs 21, 21. The base plate 25 is provided. The base plate 25 and the lower side portions 23, 23 are fixed to each other by an appropriate means such as welding or screwing. The length of the leg 21 in the direction X of the major axis (the length of the major axis), that is, the lateral width of the gantry 2 is wider than the lateral width of the pump body 1. Here, the lateral width of the pump body 1 refers to a strainer 12 in a cylindrical pump body 1 (that is, the same shape as the submersible pump described in the conventional example) in which the strainer 12 has a diameter larger than the diameter of the housing 11. And the diameter of the housing 11 in the cylindrical pump body 1 in which the strainer 12 has a shorter straight diameter than the diameter of the housing 11.

As for the pump body 1, as shown in FIG. 2, the lower ends of the multiple columns 12 a forming the strainer 12 are installed on the base plate 25 of the gantry 2. Specifically, the lower ends of the columns 12a ... And the base plate 25 are fixed with removable stoppers such as bolts and nuts, or the lower ends of the columns 12a ... Are welded to the base plate 25. It is installed by

In this embodiment, in the legs 21 and 21 of the gantry 2 and the pump body 1 installed on the gantry 2, the reaction force of the water discharged from the discharge port 13 and the weight of the drain hose are increased.
