Abstract: "Method of protection from flood water penetrating into lodgements (of any kind) through air vents and other low located openings. AND, for securing natural ventilation of said lodgements despite the most of any particular one may be submerged under the water. The Method can be implemented by transferring the air extraction' functions from the existing low located air vents (that may be located well under water) to artificial air vents with adjustable (up and down) location above the flood level. The vertical position of the artificial vent may be adjusted with regard to weather prediction (with some reservation) In the way that the artificial vent is continuously opened for air but closed for flood water. A set of airways (or a single airway of maximum height) that covers the highest level of flood, rectangular or round, made from plastic-PVC or metal may be used for adjusting the position of the air entrance with regard to the level of expected flood. The last installed piece of said set (or the single one) that contains the air entrance is, In fact, said "flexible air artificial vent". 20f2/O322 The steps of air circulation for natural extraction with regard to said new Method are: atmosphere - down to artificial vent - through insulated old vent (or new made opening in the wall) and closed (insulated) airway - up through the lodgement to the roof - up to atmosphere. -The openings in lodgement such as external doors, windows and, possible, other (with the exception of vents) can be insulated manually by seals from the shelves to work together with said Method of protection from flood water penetrating into lodgements (of any kind) through air vents and other low located openings. 2 oa /o03 S ABSTRUCT (installation 1) The device that in the 1-st form of the installation (See Fig 1) Contains: -90 degrees air diverter 2 - type of plumbing elbow, made manually or from the shelfs, plastic PVR or metal, round or rectangular, or otherwise - Flange 1 of, preferably, the same shape (rectangular) and the same dimensions that the original grate has got, with halls 4 for clamping the flange to the outer wall of the lodgement, with insulation 3 to insulate the flange against the house's wall with central opening in mentioned flange 1 that corresponds to the same shape and dimensions that outer section of the horizontal part of the diverter 2 has. So the opening in the said Flange 1 may be penetrated by said horizontal part of the diverter 2 without gaps (tightly) to make the insulation' job easier, The flange 1 may be clamped to the vertical part of the diverter (elbow) 2 by at least 2 rivets (or otherwise) 20f2/10 032 The vertical part of the diverter (elbow) contains socket 5 to accommodate the said vertical airway 6 for covering the possibly highest level of flood. -contains an airway 6 of the length that covers the possibly highest level of flood. -on some distance against said airway 6 the device contains a cap 7 to protect the said airway and the entire device from being penetrated by dirt and rain. - clamp(s) 8 support the airway 6. Alternatively, a flexible tube may be used instead of the diverter and set of plumbing airways or airway 6. 20-/2 63 2 ABSTRUCT (installation 2) The installation (device) that in 2-nd form of the invention (see Fig 2) comprises mostly the same parts that the installation 1 has: - 90 degrees air diverter 1. - One socket 5 to support the long airway 3. - a horizontal part 2 of diverter 1 that penetrates the lodgement's wall into the vent. -at least 2 strip clamps 4 to secure the installation against the wall - Vertical long airway 3 of appropriate length to cover the highest level of flood that can be protected. -The cap 7 above the upper end of the tube must be organised to prevent rain and any small parts to enter the tube. There is an understanding that at installation the horizontal part 2 of the diverter 1 has to penetrate the wall into the said vent opening to be fixed and insulated into the wall by building materials. The installations of both forms are going to be simple for manufacturing, reliable and cheap. It may be assembled for any weather prognosis in seconds. Without threat of flood the said long airway(s) 3 may be disassembled by lifting the said airways up ABSTRUCT (inStallation 3) The said Method of preventing flood water enter a lodgement by lifting artificial suction point up,( higher than possible level of flood water) may be used for brick -veneer lodgements that contain made for ventilation regular gaps( called- weep holes) between every 3 bricks in the row. The said weeps in conjunction with existed 'rain screen cavity' behind the brick' wall provide reasonable defence against rain' water but not so reliable - against flood water. It is even more important that any flood that covers weeps holes shuts down natural ventilation with not good consequences for a household. To avoid the said consequences, for the purpose to keep natural ventilation alive independently of flood level, the so called -'artificial air vent' has to be organised at height that is definitely higher than it is predicted by whether prognoses. The purpose can be served (see fig 3)by horizontal 1 and vertical 2 rectangular shape strips of, preferably, plastic material(or metal) with insulation 3 against the wall and preferably rectangular ditch 4 that may accommodate the height of said weeps between bricks along horizontal strips 2012 IO co8a and the horizontal strip 1 with weeps located above and against said weeps together with vertical strip 2 make 90 degrees elbow that has air enter opening at the top of vertical strip ( said 'artificial vent') for feeding the horizontal strip, that is closed from both sides and accumulates the air for feeding the house ventilation. The said 90 degrees elbow: In combination the vertical strip of the elbow represents the artificial vent (airway) that is located above the possible flood level and pumps air into the horizontal part of elbow that accumulates air for spreading it between said gaps (airways) for a lodgement's ventilation. A cap to protect the said airway and the entire device from being penetrated by dirt and rain is compulsory.
