Description

The present invention relates to a main body structure for providing a backup function in a pumping / draining pump unit among equipment members constituting a pumping / draining system.

In a conventional drainage system, it is necessary to use a drainage pipe of about 40 to 75 mm in order to cause the drainage to flow down by gravity using a drainage pipe provided with a gradient. For this reason, it may be difficult to install a drain pipe when moving around or adding water around an existing house.

By using a small pumping / drainage pump unit, the pumping / draining system can make subsequent drainage pipes a small-diameter drainage pipe with a diameter of about 20 to 25 mm and eliminate the need for a gradient. As a result, even when there is no space under the floor such as a direct floor, it can be drained using the space in the wall or behind the ceiling, and in recent years it has become popular in Japan.

This small pressure drain pump unit has a structure as shown in FIG. 2, and a small submersible pump 6a and a switch 6b for detecting the water level and detecting the operation / stop of the motor are housed in a case and integrated. It is easy to do.

In the case of a failure in a small pumping drainage pump unit, it was possible to repair it by opening the lid 2 provided on the upper part of the main body case 1 and replacing the drainage pump unit 6 inside. Until the repair was completed, there was a drawback that it was not possible to drain.

In addition, a product in which two drainage pump units 6 are built in one main body case and are automatically operated alternately during normal times is also commercially available. The submersible pumps are connected to a common control unit and are automatically operated alternately. When one drainage pump unit 6 breaks down, the other drainage pump unit 6 can drain the water. However, because there is only one control unit, when a large amount of wastewater flows in, there is an advantage that it can handle two units at the same time, but when the control part breaks down, it can not be drained. There were drawbacks.

Furthermore, since the operation time of the two drainage pump units 6 is used at approximately the same level, the deterioration due to use proceeds at the same level, and if one drainage pump unit breaks down, the time is not increased so much. One drainage pump unit is about to be replaced.

Since there are two or more drainage pump units 6 in the main body case 1, a partition wall 3 is provided so as to partition each, and the pump chamber inside the main body case 1 is divided so that drainage flows into at least one pump chamber. Inflow port 10 is provided.

The height of the partition wall 3 is set higher than the operating water level of the submersible pump. In addition, the partition wall 3 may be provided with a notch 4 or a flap 5 at the upper end of the partition wall 3 as a function for adjusting the height.

The drainage pump unit 6 is a combination of a submersible pump 6a and a switch 6b that detects the water level and senses the operation / stop of the motor, and is configured to be driven independently with a separate control unit.

By providing the partition wall 3 inside the main body case 1, it does not flow into the adjacent pump chamber when the water level is low. In normal times, when drainage flows, only the water level in the pump chamber on the inflow side rises, and when it reaches the operating level, it is discharged by the drainage pump unit 6. If the drainage pump unit 6 does not move due to a clogging due to a foreign matter, the drained water can flow into the adjacent pump chamber through the partition wall, and is discharged by the drainage pump unit 6 ′ when the operating water level is reached. Is done. That is, when the inflow-side drain pump unit 6 breaks down, the drainage overflows from the inflow-side pump chamber to the backup-side pump chamber, and the drainage pump unit 6 'automatically starts a backup operation. Even when a failure occurs, the user can drain the water in the same manner as normal without being aware of the failure.

The occurrence of a failure is detected by detecting that the drainage pump unit 6 has failed, the water level in the pump chamber on the inflow side has reached an abnormal level, or that an overflow has occurred using a sensor such as an electrode rod. The signal may be connected to an alarm panel or the like to notify the user by an indicator light or a buzzer.

Upon receiving the alarm notification, it is necessary to perform inspections and repairs. However, since the drainage can be performed by the backup drainage pump unit 6 ′ until the repair is completed, the main drainage pump unit 6 Allow time to complete repairs.

Usually, since the drainage does not flow into the pump chamber on the backup side, the drainage pump unit 6 ′ for backup does not come into contact with the drainage at normal times and does not get dirty. This has an advantage that the possibility of deterioration or failure caused by use can be suppressed. From another point of view, it can be considered that the backup pump room secures a storage space for a spare replacement drainage pump unit. Even if a replacement drainage pump unit cannot be obtained immediately, if the drainage pump unit 6 'is replaced with the drainage pump unit 6 and restored, it can be repaired in a state where there is no problem for normal use. After that, if a replacement drain pump unit can be obtained, it can be stored in the position of the drain pump unit 6 'on the backup side. In the case of an independent drain pump unit including the control unit, the drain pump The backup function can be restored without stopping the unit 6.

For example, the notch 4 provided at the upper end of the partition wall 3 provides a function capable of adjusting the height, so that it can be adjusted to overflow into the pump chamber on the backup side before overflowing from the drainage device. It is. In particular, when connected to a drainage device with a low overflow edge of a drainage device such as a grease interceptor, it is possible to respond flexibly even after installation when it is necessary to overflow the pump chamber on the backup side at a lower water level than usual.
