Method and device to collect water

Abstract

The present invention relates to a method and a device to collect rain water, and during favorable conditions, condense humidity out from the air during night time by using a foldable membrane and a hose to bring the water out to a transport container. To obtain mobility the supporting walls of the equipment are inflatable and may be temporarily connected to the ground but also to a boat or similar when floating.

Claims

1. A device for collecting rainwater as a drinking water, said device comprising: at least one inflatable support wall (1) arranged to allow the device to float on water that is not the drinking water; a mobile rainwater collecting membrane (2), where outer edges of said membrane are attached to the at least one inflatable support wall (1), said membrane (2) comprising a substantially centrally positioned drain hole (3); an outlet hose (9) having two ends; and wherein said device is arranged to allow gravimetric drain of the rainwater to occur through the substantially centrally positioned drain hole (3) of the membrane (2) and through the outlet hose (9), one end of said outlet hose (9) is connected to the substantially centrally positioned drain hole (3) of the membrane (2) at an underside of said membrane (2) and inside of said at least one inflatable support wall (1); characterized in that an outlet (4) of the other end of said outlet hose (9) is arranged outside of said at least one inflatable support wall (1) so that the outlet (4) of the drain hose is situated on a height over the water that is not the drinking water when the at least one inflatable support wall (1) is inflated and floating on the water that is not the drinking water, and wherein said outlet (4) is arranged to allow said gravimetric drain of the rain water from said device to a collection vessel without a device supporting substrate being able to contaminate the collected rainwater.

2. The device according to claim 1, wherein the wear exposed parts are made of reinforced plastic or rubber foil.

3. The device according to claim 1, wherein inflation of the at least one inflatable support wall is configured to inflate via at least one gas cartridge to via at least one wall connection (7).

4. The device according to claim 3, wherein a valve attached to the at least one inflatable support wall (1) opens to permit the gas cartridge to inflate the support walls, when the support walls are in contact with the water that is not the drinking water.

5. The device according to claim 1, wherein the membrane (2) is funnel-shaped, and the outlet hole (3) to the drain hose is provided with a filter for water treatment, wherein the filter includes activated carbon.

6. The device according to claim 1, wherein attachment eyelets (6) are fitted for anchoring the device.

7. The device according to claim 1, wherein a holding rope or handles is/are located in top of the at least one inflatable support wall.

8. The device according to claim 7, wherein the supporting at least one inflatable support wall has a buoyancy in water and is dimensionally arranged to include holding rope or handles arranged on the device.

9. A method for collecting rain water comprising: attaching a mobile rainwater collecting membrane (2) to an inflatable support wall (1), wherein said inflatable support wall (1) allows the device to float on water; inflating the inflatable support wall (1); floating the inflatable support wall (1) on water; wherein said device allows gravimetric drain of the rain water to occur through a substantially centrally positioned drain hole (3) of the membrane (2) and through an outlet hose (9) connected at one of its ends to said drain hole (3) at an underside of said membrane and arranged inside of said inflatable support wall (I) and the other end of said outlet hose (9) forming an outlet (4), said outlet (4) is arranged on an outside of said inflatable support wall (1), wherein the outlet (4) is situated on a height over the water, and wherein said outlet (4) allowing drain of the collected rain water to a collection vessel without a device supporting substrate being able to contaminate the collected rainwater.

10. The device according to claim 9, wherein the outlet hose (9) extends through the inflatable support wall (1).
