(First embodiment)
A storage tank 10 according to a first embodiment of the present invention will be described with reference to FIGS. 1A to 1C.

As shown in FIGS. 1A to 1C, the storage tank 10 is connected to a plurality of storage members 12, an inflow pipe connecting member 14 connected to one end of the storage member 12, and the other end of the storage member 12, respectively. An outflow pipe connecting member 16 is provided, and a storage space 20 for storing drainage is formed by the storage member 12, the inflow pipe connecting member 14, and the outflow pipe connecting member 16.

The storage member 12 is a tubular member having a circular cross section made of vinyl chloride resin. In the storage tank 10 of this embodiment, as shown to FIG. 1A, the three storage members 12 of the same shape are arranged in parallel. In addition, the storage member 12 is arrange | positioned so that an axial center may incline downward toward the downstream from upstream.

The inflow pipe connecting member 14 is a tubular member having a diameter larger than that of the storage member 12, and one end in the longitudinal direction is fitted and connected to one end of the storage member 12. As shown in FIG. 1B and FIG. 1C, the coupling position of the inflow pipe connecting member 14 and the storage member 12 can be adjusted by adjusting the fitting depth of the inflow pipe connecting member 14 to the storage member 12. And the magnitude | size of the storage space 20 is made variable by changing the connection position of the inflow pipe connection member 14 and the storage member 12. FIG.

An inflow pipe connection port 14 A having a smaller diameter than the end face of the inflow pipe connection member 14 is formed in the lower portion of the end face at the other end in the longitudinal direction of the inflow pipe connection member 14. An inflow pipe 22 is connected to the inflow pipe connection port 14 A, and wastewater from an upstream watering device or the like (not shown) flows into the storage space 20 through the inflow pipe 22.

A communication hole 18 having a diameter smaller than that of the inflow pipe connection port 14A is formed in the upper part of the end surface of the inflow pipe connection member 14 above the inflow pipe connection port 14A. A communication pipe (communication member) 26 made of vinyl chloride resin is connected to the communication hole 18.

The communication pipe 26 is disposed so as to extend in the horizontal direction along the end surface of the inflow pipe connection member 14, and the communication holes 18 of the three inflow pipe connection members 14 arranged in parallel are communicated with each other by the communication pipe 26. When the water level of the wastewater in the storage space 20 rises to the height of the communication hole 18, the wastewater flows out to the other storage space 20 adjacent through the communication hole 18 and the communication pipe 26.

Further, a vent hole 28 having a smaller diameter than the communication pipe 26 is formed on the outer peripheral surface of the communication pipe 26, and the center of the vent hole 28 is located above the center of the communication pipe 26. Further, a vent pipe 30 is connected to the vent hole 28, and the air in the storage space 20 can be released to the outside through the communication pipe 26 and the vent pipe 30. The vent pipe 30 is arranged so as to extend along the longitudinal direction of the storage member 12, and the distal end portion of the vent pipe 30 is connected to a downstream not shown pipe.

The outflow pipe connecting member 16 is a tubular member having a diameter larger than that of the storage member 12, and one end in the longitudinal direction is fitted and connected to the other end of the storage member 12. As shown in FIGS. 1B and 1C, by adjusting the fitting depth of the outflow pipe connecting member 16 to the storage member 12, the coupling position of the outflow pipe connection member 16 and the storage member 12 can be adjusted. The size of the storage space 20 is variable by changing the connecting position between the outflow pipe connecting member 16 and the storage member 12.

An outflow pipe connection port 16 A having a diameter smaller than that of the end face of the outflow pipe connection member 16 is formed in the lower portion of the end face at the other longitudinal end of the outflow pipe connection member 16. The upper part of the end surface of the outflow pipe connecting member 16 is a curved surface protruding outward in the longitudinal direction.

The outflow pipe 24 is connected to the outflow pipe connection port 16A, and a confluence joint is connected downstream of the outflow pipe 24. The drainage of the storage space 20 flows downstream through the outflow pipe connection port 16A and the outflow pipe 24, and is drained in a full flow with a drop, thereby generating a siphon force that is a force for drawing the upstream drainage.

According to this embodiment, the storage space 20 is formed by the three members of the inflow pipe connection member 14, the outflow pipe connection member 16, and the storage member 12. For this reason, since the members can be freely combined, for example, by replacing the storage member 12 with a different length, the capacity of the storage space 20 can be changed according to the required capacity of the storage space 20. .

Moreover, since the connection position of the inflow pipe connection member 14 and the outflow pipe connection member 16 with respect to the storage member 12 can be adjusted, the relative position can be changed by changing the connection position of the inflow pipe connection member 14 and the outflow pipe connection member 16. In other words, the capacity of the storage space 20 can be changed without replacing the member itself. For this reason, compared with the case where the whole storage tank 10 is replaced | exchanged, the capacity | capacitance of the storage space 20 can be adjusted easily.

Further, the three storage spaces 20 are communicated with each other through a communication hole 18 and a communication pipe 26 connected to the communication hole 18. For this reason, the drainage can be caused to flow out from the storage space 20 to another adjacent storage space 20 by the communication hole 18 and the communication pipe 26, and the amount of water that can be stored can be supplemented by the other storage member 12.

In addition, the outflow pipe connection port 16A is formed in the lower part of the end surface of the outflow pipe connection member 16, and the upper part is a curved surface. For this reason, the drainage of the upper part of the outflow pipe connection member 16 is divided and circulated by the curved surface part, so that the flow of drainage from the inflow pipe connection port 14A to the outflow pipe connection port 16A flows out of the outflow pipe connection port 16A. It is possible to suppress the hindrance from being drained toward the inflow pipe connection port 14 A without being discharged, and the drainage can be efficiently discharged from the outflow pipe connection port 16 A.

An inflow pipe connection port 14A and a communication hole 18 are formed in the inflow pipe connection member 14 connected to one end of the storage member 12, and an outflow pipe connection port is connected to the outflow pipe connection member 16 connected to the other end of the storage member 12. 16A is formed. Furthermore, the axial center of the storage member 12 is disposed so as to be inclined downward from the upstream toward the downstream.

For this reason, drainage can flow efficiently from the inlet pipe connection port 14A to the outlet pipe connection port 16A, and downstream drainage is less likely to flow out of the storage member 12 from the communication hole 18. Therefore, the water level on the downstream side where the outflow pipe connection port 16A is provided can be raised efficiently, and the activation of the siphon can be accelerated. Moreover, it can suppress that water remains in the storage member 12. FIG.

The size of the storage space 50 is variable by changing the position.

According to the present embodiment, the connection position of the outflow pipe connecting member 46 with respect to the storage member 42 can be adjusted. Therefore, by changing the connecting position of the outflow pipe connecting member 46, the relative position between the inflow pipe connecting member 44 and the outflow pipe connecting member 46 can be changed, and the capacity of the storage space 50 can be changed without replacing the member itself. .

The inflow pipe connecting member 44 and the storage member 42 are integrally formed, and the outflow pipe connecting member 46 is separated from the storage member 42. For this reason, the capacity | capacitance of the storage space 50 can be changed also by replacing | exchanging any one of the inflow pipe connection member 44 and the storage member 42, or the outflow pipe connection member 46 to a thing with a different capacity | capacitance. Therefore, compared with the case where the whole storage tank 40 is replaced | exchanged, the capacity | capacitance of the storage space 50 can be adjusted easily.

It can be stretched. An inflow pipe connecting member 64 is fitted and connected to one end of the storage member 62 in the longitudinal direction, and an outflow pipe connecting member 66 is fitted and connected to the other end.

According to this embodiment, since the bellows-like portion 62A is formed on the outer peripheral surface of the storage member 62, the storage member 62 can be expanded and contracted. Accordingly, by changing the length of the storage member 62 by expanding and contracting the storage member 62, the relative position of the inflow pipe connection member 64 and the outflow pipe connection member 66 can be changed, and the capacity of the storage space 70 can be changed.
