Description

[Detailed Description of the Invention] The present invention relates to a guide device for a submersible pump that allows the position and size of an opening for guiding the submersible pump into water to be freely set.

For example, in the case of sewers, since sewer pipes are buried over long distances, relay pump equipment is provided along the route of the sewer pipes. This relay pump equipment is for raising the water level of sewage in a sewer pipe by a pump to promote the flow of sewage, and for example, a sewage relay pump unit as shown in FIG. 1 is used. In the figure, reference numeral 1 is a frame block of a manhole buried underground, and this frame block 1 is made of concrete and formed into a cylindrical shape with a bottom. Such a frame block 1 is placed on a foundation 2 and an upper opening 1 of the frame block 1 is opened.
It is installed so that a is approximately equal to the ground surface. A metal receiving frame 3 is fixed to the edge of the upper opening of the main body block 1, and a disc-shaped lid 4 is removably placed on this receiving frame 3 to close the upper opening 1a of the main body block 1. It's becoming like that.

Furthermore, an upstream sewer pipe 5, which is an inflow pipe, is connected to the side peripheral wall of the frame block 1 so as to communicate with the inside of the frame block 1, so that sewage flows into the frame block 1 from the sewer pipe 5. ing. A mounting base 6 is provided at the bottom of the main body block 1, and a discharge pipe 7 via a discharge bent pipe 7a and a water level gauge 9 are mounted on this mounting base 6. The discharge pipe 7
has a self-attachable flange 10 at the end, and a check valve 1
1. It is connected to a downstream sewer pipe 13, which is an outflow pipe, via an on-off valve 12. This sewer pipe 13
is located above the sewer pipe 5, penetrates the side peripheral wall of the frame block 1, and extends to the outside. The guide column 8 is attached to the discharge bent pipe 7a, and the upper part of the guide column 8 is fixed to the receiving frame 3 and reaches the upper opening 1a of the frame block 1.
Further, the water level gauge 9 includes a protection tube 14 formed of a porous tube and a signal line 16 having water level detectors 15, 15.
It is formed from.

As shown in FIG.
are arranged side by side. Submersible pumps 19 are connected to such guide columns 8 through guide fittings 18, respectively.
are provided so as to be able to rise and fall freely, and these guide columns 8 and guide fittings 18 allow the submersible pump 1 to be
Nine guide devices are configured. The discharge port of the submersible pump 19 is connected to the automatic attachment/detachment flange 1 with the submersible pump lowered to the lower end of the guide column 8.
It is designed to collide with 0. Further, the submersible pump 19 is designed to be carried in and out from the upper opening of the frame block 1 with the lid 4 removed.

In such a conventional guide device, the submersible pump 1
9 is moved up and down directly above the installation position to carry in and out, the upper opening of the main body block 1 must be placed directly above the installation position of the submersible pump 19, which is a problem that restricts the design of the upper opening 1a of the main body block 1. It was hot.

The technical problem to be solved by the present invention is to solve the problem that the position of the opening through which the submersible pump is carried in and taken out is restricted to be directly above the installation position of the submersible pump.

The technical means taken to solve the above technical problem is to install a reference pipe made of a straight circular tube upright, and to twist the pipe in the circumferential direction of the reference pipe with an equal distance between the reference pipe and the reference pipe. A circular bent pipe with a bent part is provided, and a submersible pump can be moved up and down along both pipes.

Therefore, the submersible pump ascends and descends around the reference pipe while rotating along the reference pipe and the bent pipe in the circumferential direction of the reference pipe.

With the above technical means, the opening through which the submersible pump is carried in and out is not necessarily restricted to be directly above the installation position of the submersible pump, and the above technical problem is solved.

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 3 to 5. In addition, Figures 1 and 2 in the figure
Items with the same reference numerals as those in the figures indicate the same or corresponding parts.

In the figure, reference numeral 20 denotes a straight circular reference pipe, and this reference pipe 20 is attached to the discharge curved pipe 7a. A circular bent pipe 21 is vertically installed at a predetermined distance from the reference pipe 20. A bent portion 22 is formed in the middle portion of the bent pipe 21, equidistant from the reference pipe 20 and twisted to an angle θ in the circumferential direction of the reference pipe 20, as shown in FIG.

As shown in FIG. 5, two sets of these pipes 20 and 21 are arranged side by side in the frame block 1, and the bent portions 22 are twisted inwardly toward each other. And both the pipes 20, 21
A submersible pump 19 is provided via a guide fitting 23 so as to be able to move up and down.

With such a configuration, the submersible pump 19 installed on the left side is first carried in through the opening 24 shown by the solid line in FIG.
1, it descends while turning by an angle θ and is installed at the installation position shown by the broken line. Then,
The submersible pump 19 on the right side is similarly carried in and installed.

Therefore, in this embodiment, two submersible pumps can be carried in and out through the opening 24 while greatly reducing the opening area of the lid 4 shown by the broken line in FIG. Therefore, the degree of freedom in designing the position and size of the upper opening 19 of the frame block 1 is further improved.

Note that the present invention is not limited to the above embodiments; for example, the number of sets of reference pipes and bent pipes is not limited to two, and the design of the rotation direction and rotation angle of the submersible pump can be changed as appropriate. Furthermore, the present invention is applicable not only to the sewerage relay pump unit as in the embodiment, but also to systems in which a submersible pump is carried in and out through an opening.
