Description

  The present invention relates to a malodor-preventing drainage facility, and more particularly, to a malodor-preventing drainage facility having a pump attachment / detachment mechanism that can easily lift and lower a pump in a space with a height restriction.

  In general, in a facility where sewage, wastewater, river water, or the like is temporarily stored in a water tank and drained by a pump, the liquid may contain dust or filth. Especially in buildings with underground structures, not only sewage generated in the basement, but also sewage generated in the building is temporarily stored in large drainage tanks or sewage tanks (also called pits or building pits) installed underground. May be stored. Since these temporarily stored liquids are located below the public sewer pipe, they are pumped up to the sewage sewage by a pump installed in the pit and drained to the public sewage pipe through the sewage sewage pipe. FIG. 16 is a diagram schematically illustrating a drainage facility formed in the underground portion of the building 500. As shown in FIG. 16, the basement portion B of the building 500 may be located below the public sewer pipe 80. Conventionally, the sewage and miscellaneous drainage (hereinafter referred to as sewage etc.) generated in the basement part B and the sewage generated in the building 500 are large drainage tanks (pits) installed further down through the inflow pipe 81. ) 85 temporarily stored. Thereafter, the sewage or the like is pumped up to the sewage basin 91 by the drainage pump 90 installed in the drainage tank 85 and drained into the public sewer pipe 80 through the sewage basin 93. In addition, you may drain the waste water etc. which generate | occur | produce in the 1st floor or more part of the building 500 directly to the waste water 91 by a natural flow.

  In such a facility, the pump 90 is started to operate when the water level in the drain tank 85 reaches a predetermined water level. However, if the water level in the drainage tank 85 does not reach the predetermined level and sewage remains at the bottom of the drainage tank 85 for a long period of time, the decay will progress and a bad odor will be generated from the manhole when discharged into the public sewer pipe 80 There is a case.

  The above problem is conspicuous because the drain tank 85 is too large, and the area of the bottom of the tank is large, and the amount of remaining sewage is increased. In order to improve this, in the drainage tank 85 shown in FIG. 16, the bottom plate 87 of the drainage tank 85 is provided with a gradient descending toward the pump 90, or the concave portion 89 is provided in the bottom plate 87 where the pump 90 is installed. ing. Further, by improving the operation method of the pump 90, for example, after the pump 90 is operated to the pump-off water level WL2, the operation of the pump 90 is continued for a predetermined time so as to reduce the amount of remaining sewage as much as possible. ing.

  However, even if improved as described above, the amount of residual sewage and miscellaneous wastewater is still large, and it has not yet been possible to suppress the progress of decay of sewage and miscellaneous drainage. For this reason, a malodor prevention type drainage system has been proposed in which a small cylindrical water tank (barrel) or the like is arranged in a large water tank (pit) and a pump is used in the small water tank (for example, Patent Document 1). .

In addition, a pump attaching / detaching device may be provided to install or take out the pump. For example, sewage pumps used in sewers are easily clogged by sewage, and toxic gas may be generated at the installation location. Is used. For example, an attachment / detachment device main body that is fixed in advance at an installation location and supports a fixed pipe, and an attachment / detachment flange that is attached to a pump and configured to be attachable / detachable to / from the attachment / detachment device main body, A locking rod that engages with the hook is provided on the detachable device main body, and the pump and the detachable flange are lowered vertically so that the hook and the locking rod are locked, so that the detachable flange is attached to the detachable device main body. The attachment of the detachable flange and the detachable device body is maintained by the weight of the pump,
By securing the water tightness of the discharge flow path of the pump and installing the pump and lifting the pump and the detachable flange vertically upward, the attachment of the detachable device body and the detachable flange is released, and the pump can be taken out (for example, a patent) Reference 2).

JP 2002-70142 A Japanese Patent Laid-Open No. 11-30198

  In the malodor prevention type drainage system described in Patent Document 1, the diameter of the barrel is designed in accordance with the diameter of the manhole so that the barrel can be carried into the pit through the manhole formed in the pit. Moreover, since the diameter of a barrel is restrict | limited, one submersible pump is arrange | positioned at one barrel. Since the diameter of the barrel cannot be increased, it is difficult for a plurality of people to enter the barrel, and operations such as cleaning the barrel are complicated. When maintaining the submersible pump, for example, the pipe connected to the pump is removed and the pump is pulled up from above the barrel. In a submersible pump for sewage, the attachment / detachment device may perform the attachment / detachment of the pump, but it is difficult to install the attachment / detachment device in a limited space of the barrel.

  Conventionally, a float type water level sensor is installed in the barrel, but the space in the barrel is limited and it may overlap with the installation location of the pump. Install the float type water level sensor in the correct position. It was difficult. Since the pump is started / stopped based on detection from the float type water level sensor, if the water level sensor is not properly installed, sewage will not be discharged properly.

  In order to cope with these problems, a drainage facility configured to discharge a dirty water from the water tank by arranging a drainage pump outside a small water tank in a pit such as a barrel can be considered. The maintenance of the pump becomes easy by providing the drainage pump outside the water tank. However, odors and toxic gases may be generated in the pit where the aquarium is located, so when pump replacement or maintenance is performed, the pump is lifted out of the pit so that no people can enter the pit. There is a demand for replacement and maintenance of the pump. Therefore, a pump system for separating the drainage pump from the water tank piping and pulling it out of the pit without people entering the pit as much as possible is desired.

  Further, in the pump attaching / detaching device described in Patent Document 2, when the weight of the pump is light, the mating surface (joining part) between the attaching / detaching flange and the attaching / detaching device main body is opened, and water leaks. There is. Moreover, since the attachment / detachment device main body is provided in the vicinity of the pump, when trouble occurs in the attachment / detachment device main body, an operator must enter and work in the pit or the water tank.

  Further, the height of the space for maintenance of the pit or the water tank (for example, the basement portion B in FIG. 16) may not be high enough to pull out the discharge pipe together with the pump. For example, as shown in FIG. 17, in order to take out the pump from the barrel in the pit, it is necessary to remove the discharge pipe connected to the pump with a flange and a bolt. Even if a conventional pump attaching / detaching device is used, Personnel must enter the pit or barrel.

  It is an object of the present invention to provide a malodor-preventing drainage system equipped with a pump attachment / detachment mechanism that can greatly reduce the need for an operator to enter and work in a pit or a water tank.
