Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pump mounting device for a panel water tank in which a large number of unit plates formed of metal plates or plastics having flanges on all four sides are joined together at the flanges, and the unit plates constitute a tank wall. . Conventionally, in such a panel water tank, a submersible pump was installed inside the tank or a pump room was provided outside the tank in order to pump the water inside the tank to the outside. However, when installing a submersible pump inside a tank, there is no need for space for a pump room outside the tank, but on the other hand, in the tank for maintenance and repair of the pump, it is necessary to open the drain and drain all the water inside the tank. If the pump room is installed outside the tank, it is not necessary to drain water during maintenance or repair of the pump, but on the other hand, extra space is required to install the pump room near the water storage tank.

Therefore, the present invention solves the above-mentioned conventional problems by mounting a pump on the unit plate that constitutes the side or bottom tank wall of a panel water storage tank, separating it from the inside of the tank. Either integrally with the unit plate and separated from the inside of the tank by a separator plate, or formed separately from the unit plate and fixed to the outer surface of the unit plate, with both end surfaces protruding outside the unit plate isolated from the inside of the tank. A cylindrical pump accommodating part is provided, and a cylindrical pipe is provided on one end surface of the pump accommodating part to support one end of the pump within the accommodating part and to fix a suction pipe connected to an external pipe communicating with the bottom of the water tank. The socket is fixed, and the other end face is provided with an opening that allows the pump to be inserted and removed in the axial direction at a position aligned with the socket, and a cylindrical second socket that fixes the discharge pipe of the pump is attached to and removed from the edge of this opening. It is characterized by a possibly fixed configuration.

Embodiments of the present invention will be described below with reference to the accompanying drawings. The first embodiment shown in Figs. 1 to 6 is formed by molding a unit plate 2 that integrally has a pump accommodating part 1 that swells and projects outward from the outer surface, and has only one unit plate 2 and no pump accommodating part. A large number of ordinary unit plates 3 with the same external shape are used, and the four circumferential collars 2' and 3' of each unit plate are joined to form a tank wall, in this case one side, and the unit plate 2 located at the bottom of the side is The case where the pump 4 is attached to the pump housing part 1 is shown. The pump 4 used here is a well-known rod-shaped submersible type, and the cylindrical body 4' with one end closed has a water intake port 4a around the middle part.
A discharge pipe 4b is connected in an extended manner to the discharge port at the other end, and the pump has a support that is one size larger than the outer diameter of the body 4' and covers the area from the other end to the vicinity of the water intake in the middle. A cylinder 5 is attached, and three or more inclined pieces 5' are attached to the inner periphery of one end of the support cylinder so as to face radially inward in order to support the pump concentrically within the cylinder.

The pump accommodating portion 1 of the unit plate 2 is formed to be horizontally long and approximately equal in width to the unit plate in order to horizontally mount the pump 4 therein.

In order to fix the support cylinder 5, an opening is provided in one end surface 1a of the side part of the pump accommodating part 1 protruding from the outer surface of the unit plate 2, and one end of the support cylinder 5 is provided with a large diameter part 6a that fits into the inner periphery. A packing 6' is fitted into the small diameter cylindrical part 6b of a stepped cylindrical socket 6 having a small diameter cylindrical part 6b that matches the inner diameter of the opening, and the packing 6' is passed from the inside of the pump accommodating part through the opening and protrudes outside. let me,
A nut 7 is screwed into the male thread on the outer periphery and tightened to the outer surface of the end surface 1a of the housing portion. Then, a suction pipe 9 that connects the pipe 8 that communicates with the bottom of the tank is fitted from the outside into the small diameter cylindrical part 6b, a packing 10 is applied to the end surface of the small diameter cylindrical part, and a bag is fitted outside the suction pipe 9. The nut 11 is screwed into the outer circumference of the small diameter cylindrical portion with a male thread and tightened, and the cap nut 11 compresses the packing 10 on the end face of the small diameter cylindrical portion, and the compressive force of the packing tightens the suction pipe 9 from around the small diameter cylindrical portion. Fixed to.
Incidentally, the suction pipe 9 and the piping 8 are connected via a manually operated on-off valve 12.

The other end surface 1b on the other side of the pump accommodating part is provided with an opening 1b' having a diameter that allows the pump to enter and exit, and from this, the pump is inserted into the accommodating part 1 from the outside with one end of the pump facing forward. is pushed into the support cylinder until it is received by the aforementioned inclined piece 5'. Note that the positions of the openings on each end face of the housing portion are aligned. Then, a large diameter portion 13a is provided with a flange that abuts the edge of the opening 1b'.
Then, using a stepped cylindrical second socket 13 having a small diameter part 13b that matches the outer diameter of the discharge pipe 4b of the pump, the small diameter part 13b is fitted into the discharge pipe 4b and penetrated, and the collar 13' is inserted into the opening 1b. The second socket 13 is fixed to the end surface 1b by connecting it to the edge of the small diameter portion 13b with bolts and nuts, and the packing 14 is applied to the end surface of the small diameter portion 13b.
By screwing and tightening the cap nut 15 into the male thread on the outer periphery of the small diameter portion 13b, the packing 14 is compressed, and the compression force of the packing fixes the discharge pipe 4b from around it. A pipe 16 that leads water to a water supply location is connected to the tip of the discharge pipe 4b. Note that a gasket is placed between the collar 13' of the second socket cylinder and the edge of the opening 1b'.

Then, before or after these operations, a strong separating plate 17 is attached by fixing the circumference with adhesive or the like to the inner surface of the unit plate 2 or the inner surface of the pump accommodating part, and the part where the pump 4 is housed is isolated from the inside of the tank. I'll leave it there.
In addition, in the embodiment shown in FIG. 7, a pump accommodating part 1' having an end face on each side corresponding to the pump accommodating part 1 of the unit plate 2 of the above example is formed into a shell shape from plastic or a metal plate, and this shell is made of plastic or a metal plate. This is a case where the edge flange is fixed to the outer surface of the normal unit plate 3 by gluing, bolting, etc., and the pump 4 is installed in the same manner, so the same components are given the same reference numerals and explanations are omitted. do.
In this case, the original unit plate itself is the separator plate 1.
It plays the role of 7.

In either case, the bolt or nut 18 that fixes the collar 13' of the second socket 13 to the edge of the opening 1b' can be operated from outside the tank, and for this reason a nut or bolt head is glued to the inner surface of the end face 1b. If using a bolt, place the screw shaft through the end face and protrude outside. Further, the wiring 19 for supplying power to the motor and for grounding inside one end of the pump 4 can be sealed and pulled out from a hole formed on the circumferential surface of the large diameter portion 13a of the second socket 13, and this structure is different from the conventional one. The procedure for pulling out the submersible pump outside is the same as when it is installed inside a tank. Furthermore, there is an air bleed socket 20 on the top surface of the part that houses the pump, and a drain port 2 that can be opened by removing the plug on the bottom surface.
Set up 1.

In this way, the present invention accommodates the pump in the pump accommodating part that protrudes outside the unit plate, so there is no need for space for installing a pump chamber outside the tank, and the part that accommodates the pump is separated by the separator plate 17 or It is isolated from the inside of the tank by the unit plate itself, so when maintaining or repairing the pump, open the drain to drain the water inside the pump housing part (of course, keep the on-off valve 12 closed), and then drain the water from the pump housing part by opening the drain. After removing the cap nut 15 of the socket, remove the second socket and pull out the pump to inspect and repair, and when finished, reinstall it by reversing the procedure. Therefore, it is a major undertaking that requires all the water in the tank to be drained out, and workers enter the tank through a manhole installed in the unit plate on the upper tank wall and perform inspections and repairs using flashlights. It has an innovative feature that eliminates all troublesome and time-consuming work.

There are lengths in the axial direction of the pump, and if there is one longer than the one shown in the figure, prepare a second socket with a longer axial length of the large diameter portion 13a, and a second socket with a shorter length, and adjust the length of the pump. You can use them depending on the situation.

Furthermore, in each of the illustrated embodiments, the rod-shaped pump is installed horizontally in the accommodating section, so the accommodating section 1 is formed to be horizontally elongated, but in the case of a pump that is used vertically, the accommodating section is made longer. It may be formed vertically and the pumps may be installed in the same way between the upper and lower end faces.
