Abstract

A drainage pump unit (1) for drain off faecal and/or not faecal water from a building is equipped with a pump swamp (5) that is placed in a sewer line (6,6A,7) said sewer line is equipped with an overflow (7). The sewer line is connected to a water closure (11). Down in the pump swamp there is provided a pump (8) that in dependency of the amount of waste water in the pump swamp is adapted to pump waste water, via a pump sewer line (9), down streams in the sewer line after the water closure (11). In this way it is secured that the drainage unit (1) only starts the pump under extreme circumstances, such as a cloudburst, where the water closure is active, and therefor closes for drain off and conducting of waste water from for instance, a cellar in a building. A special interesting use of the drainage unit is I connection with drain off of waste water from a single family house.

Description

DRAINAGE UNIT AND USE THEREOF
This invention relates to a drainage unit, comprising a housing, pump swamp, a sewer line, said sewer line is connected to a water closure, and where the drainage unit is adapted to drain off waste water being faecal and/or not faecal, and where there in the pump swamp is provided a pump, that is adapted to pump the waste water from the pump swamp, via a to the pump connected pump sewer line, that is connected downstream in the sewer line.
As it is well-known, climate changes have occurred in recent time, which a lot of places on the earth have led to extreme weather conditions, inter alia resulting in long term drought periods and gigantic cloudburst.
In connection with cloudburst, where big amounts of water fall, it's a problem that sewerage systems that is established in a period of approximately 100 year, are not able to deal with these water amounts. This led to a risk for reflux and collecting of water because a non-return valve, when it closes, cannot prevent water to reach and not allow water to be removed from a cellar.
A drainage unit of the type defined in the introductory part of claim 1, is disclosed in US patent no. 4.997.312. By this known drainage unit use of a plurality of component are used, inter alia a valve that is connected to the sewer line.
When a floating device detects, that bigger amounts of water are present than the sewer line can take, then the floating device activates the drainage unit in order to convey the water to a tank.
On this background it is a purpose with the invention, to provide a drainage unit being simpler constructed and immediately useable in connection with existing drain units and new constructed drain units as well.
The purpose is fulfilled by a drainage unit of the kind defined in claim 1, that is characterised in that that the sewer line inside the housing is formed with an overflow consisting of a cut off in the sewer line, said cut off is placed above the pump swamp.
So it is not necessary to connect any components to the sewer line, since it suffices to carry out a cut-out in the sewer line itself.
It is advantageous as stated in claim 2, that the cut off has a semicircular cross section.
For stable function of the pump, it is advantageous , if as stated in claim 3, that two liquid sensors are provided in the pump swamp, said two liquid sensors is connected to a control unit that in dependents of signals from the sensors transmits control signals to the pump for activating or deactivating said pump.
In this way it is prevented that the pump starts and stop continuously, since the present of a level where water activates the pump and another lower level, where the pimp is activated.
For eliminating smell inconveniences, it is advantageous, as stated in claim 4, that the part that is cut off is reinserted in on the sewer line.
A preferred embodiment of the invention is, as stated in claim 4, that that a non return valve is mounted in the pump sewer line.
As mentioned the invention also relates to a use.
This use is more closely stated in claim 6.
The invention will now be more detailed explained in connection with the figure on the single drawing.
On this figure 1 designates in its entity a drainage unit according to the invention.
The drain unit consists of a housing 3, having a closed closure 18 above, and as shown here, lying in a terrain 4. To the drainage unit a sewer line is introduced. This sewer line can come from a building, such as a house or a single- familiar house, and can be adapted to conduct waste water that can be faecal and/or not faecal, i.e. water from washing, toilets, rain water etc. The sewer line is via an overflow/passage 7 continued out of the housing 3 via the sewer line, as shown at 6A.
The overflow can consist of a simple cut out of the sewer line 6,6A, for instance having a semicircular cross section.
The part that is cut out can be reinserted in the sewer line where it is loosely attached.
Under the sewer line, a pump swamp is provided, that is intended for, cf. later, to take up water via the overflow.
In the pump swamp a pump 8 is provided, that is adapted to pump waste water through a pump sewer line 9 that is connected downstream to the waste line 6A.
Moreover it is seen that inside the pump sewer line a non return valve 10 is provided, that in a known way prevent waste water flowing back in the pump sewer line 9.
Further a coupling 19 in the pump sewer line is shown, that is used in a not specific explained way, to service the pump 8.
Down in the pump swamp two liquid level sensors 12, 13 are provided, adapted to, as explained later, to transmit control signals 15, 16 to a control unit 14, that in dependency of the control signals 15, 16 can activate/deactivate the pump 8 by a control signal 17, that is transferred from the control unit 14.
The housing 3 is equipped with a closure 18, that for instance, is in flush with the terrain 4.
Finally a known high water closure is provided in the house 11, that under for instance cloudburst, prevent waste water from the public net is led in the housing 3. Such a high water closure also prevents, that , rain water and waste water can be conveyed to the public sewerage system.
The overall drainage unit can be placed inside or outside a building, whatever is most suitable.
Now it shall be explained, how the function of the drain unit functions. When waste water from a building is transported through the sewer line 6, Then the waste water under normal circumstances will pass through the overflow 7, and further through the sewer line 6A, that is connected to the public net.
Under extreme conditions, such as a cloudburst, reflux and collecting of water is so that the high water closure closes, then rainwater and eventually waste water flow over the overflow 7 and down in the pump 5, where build up of water is provided in the pump sump 5.
When a level niveau in the pump swamp 5 corresponding to the liquid level sensors 12 level, then the pump, via the control signals 16, 17, will be activated, and pump water from the pump swamp 5 downstream in the sewer line 6A, via the pump sewer line 9.
When the cloudburst is over, the pump will continue to pump until the liquid level sensor 12 detects, that there is no influence from the waste water, because the control signal 15 is transmitted to the control unit 14, that via the control signal 17, deactivate the pump 8.
The high water closure will after the cloudburst open and flowing through the sewer line can be resumed in a normal manner.
As it will be understood, the pump will only start, when the pump swamp 5 reach the level 12 of the liquid level sensors, that only occurs under extreme weather conditions.
First of all it means that unnecessary drift of the pump 8 involving wear and unnecessary consumption of energy are totally eliminated.
