Liquid level regulator for rainwater collection tanks or the like.

The invention relates to a liquid level regulator which is additionally attached to one or more rainwater downpipes and which, thanks to the design and arrangement according to the invention, ensures the regulation of a water level in the collecting containers provided for this purpose, for example rainwater precipitation. Over time, devices of this type, such as DE-GM 8224999, have become known, in which outlet flaps are operated via a Bowden cable and rods and where the opening and closing positions are controlled by a float control when the water levels change. This, as well as the patent DE 3408142, which also describes a device for collecting rainwater in a container, are very prone to failure and complex.

It is the object of the present invention to create a device that can be easily attached to a downpipe and allows trouble-free operation for the regulated rainwater feed into the collecting tank. The liquid level controller according to the invention described here relates to a container that is designed to be square or round and that is either attached directly when installing the gutters and downpipes that drain rainwater or can also be retrofitted later.

A trouble-free control of the water flow into a collecting vessel (8) is achieved in that the incoming rainwater is collected via gutters and through downpipes (1) and flows into the level control tank (10) designed according to the invention, where it is accumulated up to the overflow edge and from there is led via corresponding connecting pipes (7) or hose lines into a connected collecting tank (8). A cover (3) within the level control tank (10) prevents immediate flow in the direction of the floor drain line (13), but at the same time opens the drainage path in the direction of the floor drain when the accumulation height in the level control tank (10) is exceeded. If, due to weather conditions, no water is to reach a collecting tank (8), the cover (3) is opened using a manually adjustable handle (9) and the sliding connecting pipe (11) is pushed via an adjusting lever (9) to connect to the upper downpipe (1) and a sealing stop (4) connected to it. This inner pipe displacement creates a direct connection between the downpipes (1 + 12), bypassing the control system within the level control tank (10) and ensuring a direct water flow into a drainage channel system.

Features, advantages and details of the innovation are listed in the following description and drawings. They show:

Figure 1

a side view with gutter and downpipe as well as the liquid level regulator attached to the downpipes and the water collecting barrel with lid connected by pipes.

Figure 2

shows the liquid level controller with sliding connection pipe cover, sealing stop cover, guide tubes, actuation for sliding connection pipe and hose or pipe connection to the collecting container.

A downpipe (1) on a building gutter shows a liquid level regulator (10) in the lower area, which is attached approx. 1.5 m from the ground and is connected to a collecting container (8) via pipes or hoses. A water drainage system is visible in the floor area at (13). Figure 2 shows the liquid level regulator with the control sliding pipe and cover system.

Here you can see that the downpipe (1) entering the liquid level regulator also has a cover (3) which, when open, directs the rainwater directly into an underground sewer pipe system, but when closed prevents the rainwater from draining through the downpipe (12). At the same time, the interior of the control tank (10) fills with water when it rains. The interior of the control tank (10) is now filled with water from the downpipe (1) up to the overflow edge of the downpipe (12) to the drain. This water runs continuously via the pipe or hose (7) into the rainwater tank (8). In the event of a heavy accumulation of rainwater, in this position with the cover (3) closed the excess rainwater is directed over the accumulation edge directly via the downpipe (12) into the drain. This ensures that the rain barrel is always filled without the rainwater collection barrel (8) overflowing.

If the weather conditions mean that the rainwater collection barrel should not be filled due to "ice", a sliding locking system (2 + 11) within the control container (10) is used to establish a connection via a lever switch (9), which allows water to flow directly into the underground drainage pipe (13) via a sealing stop (4).

Claims (2)

1. Liquid level regulator for collecting containers for rainwater or the like, characterized in that a downpipe ( 1 ) coming from above and a downpipe ( 12 ) going out below are connected to a common level control container ( 10 ), the lower downpipe ( 12 ) being arranged within the level control container ( 10 ) projecting inwards and having an adjustable cover ( 3 ) on its upper edge which, in the lower position, prevents the downpipe opening ( 12 ) for incoming rainwater from the upper downpipe ( 1 ), but rising water in the level control container is drained downwards at the overflow of the lower downpipe ( 12 ). 2. Liquid level regulator for rainwater collection containers or the like according to claim 1, characterized in that for a second control position, in which filling of the rainwater collection containers ( 8 ) is not desired, a direct sliding pipe connection ( 11 ) against a sealing stop ( 4 ) to the upper downpipe ( 1 ) can be carried out via a lever actuation ( 9 ), whereby the direct drainage of the rainwater into the lower drainage system is provided.
