Definitions

  • the present invention concerns an anti-flooding device to protect premises of various natures, low lying-areas and places or buildings of any purpose and use, or parts of them, such as basements, cellars, shops, garages or other, from floods caused by natural disasters or other.
  • the anti-flooding device can be installed, for example, in correspondence with vehicle entrances or with the entrances to buildings or suchlike access elements, or in correspondence with areas and places which are susceptible to flooding in general, whether they are above or below ground level.
  • the device can also be installed in all cases where it is necessary to contain the rise in the water level with a system which can be selectively activated, for example in correspondence with embankments or banks of water courses. lakes or seas.
  • the device can be advantageously applied in climatic zones with high rainfall or in residential coastal areas or areas near rivers, canals or suchlike where there is a risk of high tides, floods, overflowing or other.
  • the places affected can be for example buildings or parts of them situated at least partly below surface level, such as basements, cellars, garages or other places which are subject to the risk of flooding.
  • Anti-flooding barriers have been proposed in correspondence or in proximity with the access roads to the places to be protected, which can be in an inactive condition when the situation is safe, while in a dangerous situation they are activated in order to carry out their function as a barrier.
  • such barriers comprise at least a detection unit and a drive unit, in which the detection unit comprises sensors and/or detectors to provide the signal to activate the barrier in the event of danger from flooding.
  • a control system connected to the drive unit is also provided, comprising, for example, an electric motor.
  • the control system drives the drive unit to activate the barrier.
  • the known anti-flooding device is costly to produce because it needs sensors, control systems, signal transmitters and receivers, motors etc., and the height which the barrier can reach depends on the power of the drive unit.
  • the functioning of the known anti-flooding device is subordinate to the possibility of feeding the drive unit, for example by means of electric energy.
  • the known anti-flooding device has to provide protections and/or water-tight chambers in order to avoid any possibility of contact, for example, between all the electric drive systems and the water, and to guarantee it functions in conditions of safety, and this further affects the cost of production.
  • the known anti-flooding device also requires long times and high costs for installation because, for example, it needs wiring to connect the various components of the device to each other.
  • the known anti-flooding device also entails high maintenance costs, correlated to the type of construction, its components, the particular conditions in which it operates, in order to guarantee that the drive unit, the detection unit and the control system are maintained in efficient operating conditions.
  • the known manual devices also need an area or room where the barriers can be stored when not in use, so that they are available when needed.
  • Water containment devices with a mobile barrier intended mainly to be installed in correspondence or proximity to water courses, rivers and embankments are described in the prior art documents GB-A-2.464.959 , EP-A1-726.364 and GB-A-2.386.144 , as well as in WO 2009/139622 A1 .
  • Purpose of the present invention is to produce an economical anti-flooding device which is simple, automatic and functions autonomously, always efficient, which requires reduced times and costs of installation and very limited maintenance.
  • the Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.
  • an anti-flooding device for the protection of a place comprises a barrier element housed, at least partly, inside a positioning seating, open at the upper part and made under or below a positioning or walking plane; the positioning seating is connected to a section where the water enters, disposed on the opposite side with respect to the place which the barrier element has to protect.
  • the barrier element is movable, with respect to its positioning seating, between a first position in which it is completely below the positioning/walking plane, assumed when the positioning seating is empty of water, and a second position in which it progressively rises by floating with respect to the positioning seating, because of the water which, by means of the entrance section, progressively fills the positioning seating itself.
  • the barrier is therefore activated automatically, without having recourse to detection units, such as for example sensors and/or detectors, but simply by the water which progressively fills the positioning seating and generates a hydrostatic thrust which progressively lifts the barrier.
  • the movement of the barrier is carried out without having recourse to any auxiliary drive device, such as for example electric motors, and consequently the anti-flooding device according to the present invention is more economical, and also has greater guarantees of efficiency and correct functioning, compared to known anti-flooding devices, and needs lower installation times and costs, because no wiring is needed between the various components.
  • any auxiliary drive device such as for example electric motors
  • the anti-flooding device needs very little maintenance and/or simple visual inspections, since there is no need for electric drive and/or detection units.
  • the automatism of the drive of the barrier due to the water which fills the positioning seating also determines that the speed at which the barrier rises is correlated to the speed at which the water enters into the floating seating and is therefore correlated to the danger of flooding in the place to be protected.
  • the barrier according to the invention substantially consists of an upper wedge-shaped element, converging upward, and of a lower body which acts as a floating element.
  • the anti-flooding device comprises at least an end-of-travel element able to define the maximum emergence of the barrier element with respect to the positioning plane.
  • the position of maximum emergence of the barrier element is pre-determined, also in an adjustable manner after installation, according to the characteristics of the place to be protected in order to allow an adequate level of protection, as well as an adequate level of hydraulic seal.
  • the end-of-travel element comprises a profile having a shape correlated at least to the upper wedge element of the barrier; the shaped profile carries out a guide function during the progressive lifting movement, and then stops the barrier element through interference when it assumes its maximum emergence position, thus achieving the vertical hydraulic seal.
  • sealing packings at least on the side facing toward the place to be protected; the packings follow at least the profile of the upper element of the barrier, disposing itself between the upper element and the internal face of the mating end-of-travel element, in order to achieve the hydraulic seal when all the barrier has assumed its position of maximum emergence.
  • said end-of-travel position can be defined by means of an adjustment element placed, for example, at the top of the end-of-travel element and protruding toward the inside thereof.
  • a grid suitable for the passage of pedestrians and vehicles, is associated with the entrance section of the water, and is able to filter possible impurities and/or objects carried by the water flowing along the positioning plane.
  • a plate is installed on the surface, open at the upper part, of the positioning seating; the plate is hinged at one of its ends and able to close the opening when the barrier element is completely below the positioning plane, in order to create continuity therewith.
  • the plate is raised by the barrier element itself when it emerges due to the filling of the water in the positioning seating.
  • the fact that the plate covers the opening not only makes the surface suitable for passage by pedestrians or vehicles, but also prevents the entrance of foreign bodies inside the positioning seating and further reduces maintenance interventions.
  • an anti-flooding device 10 can be used, for example, but not only, for the protection of residential and industrial/commercial buildings or their appurtenances such as entrances to condos, premises and garages even underground and semi-underground, vehicle entrances or suchlike access elements, or in correspondence with areas and places in general which are susceptible to flooding, whether they are situated below or above ground level.
  • the device 10 can be advantageously used in climatic zones where there is high rainfall or in residential coastal areas or areas near rivers, canals or suchlike, where there is the risk of high tides, flooding or overflowing.
  • the anti-flooding device 10 comprises a barrier consisting of an upper wedge shaped profile 11 and a lower body or float 12; the barrier is housed in a positioning seating 15 having a front internal lateral surface 29 and a rear internal lateral surface 30.
  • the anti-flooding device 10 also comprises a plurality of end-of travel profiles 21, in this case two, the function of which will be explained more fully hereafter.
  • the positioning seating 15 is interred and has a shaped sealing element 26 disposed flush with a positioning plane, in this case a walking plane 23, on which an entrance section 16 is made, disposed on the opposite side with respect to the place which the barrier has to protect, in order to allow the water coming from the external environment flowing along the walking plane 23 to flow inside the positioning seating 15.
  • a positioning plane in this case a walking plane 23, on which an entrance section 16 is made, disposed on the opposite side with respect to the place which the barrier has to protect, in order to allow the water coming from the external environment flowing along the walking plane 23 to flow inside the positioning seating 15.
  • the entrance section 16 of the water is provided with a grid 18, attached by means of a support element 22, to filter impurities such as leaves or other foreign bodies collected and transported by the water, which would otherwise be deposited inside the positioning seating 15. This allows to reduce the maintenance and cleaning interventions inside the positioning scating 15.
  • the support element 22 also carries out a partial contrasting and end-of-travel function at the maximum emergence of the barrier.
  • the positioning seating 15 also has, on the bottom, an exit section 17 for the water, connected to a discharge well 27 by means of a discharge pipe 24.
  • the exit section 17 allows the water to be discharged and distanced from the positioning seating 15 toward the discharge well 27.
  • a pump 43 and a discharge valve 44 can be provided along the pipe 48, at least in the case where the sewage network is in a higher position than the position of the pipe 48.
  • the barrier 11-12 is mobile with respect to its positioning seating 15 along a substantially vertical direction of movement F and is moved by the effect of Archimedes' force, or hydrostatic thrust, exerted on it by the volume of water which progressively accumulates inside the positioning seating 15.
  • the movement of the barrier 11-12 is therefore achieved without recourse to any auxiliary drive units, such as an electric motor or other and, consequently, the anti-flooding device 10 is more economical than known anti-flooding devices and requires less time and lower installation costs, as it is not necessary to include either control systems and devices or wirings between the various units.
  • the upper wedge-shaped profile 11 of the barrier in the extracted position of the positioning seating 15, stops the flow of the water toward the place to be protected.
  • the lower floating body 12 has both a floating function proper, to promote the lifting by floating of the barrier 11, and also a guide function during the upward movement of the barrier 11 in the direction indicated by the arrow F as shown in figs. 4-9 .
  • the sliding in the direction indicated by the arrow F is made possible because a plurality of sliding elements 45 are applied to the sides and at the front of the float 12; the sliding elements 45 are wheels, runners or similar elements, which slide on the internal lateral surfaces 29 and 30 of the seating 15.
  • the barrier 11 tends to rise by floating with respect to the positioning seating 15, moving at least partly above the walking plane 23.
  • the shaped sealing element 26, applied to partly cover the positioning seating 15, is provided with an aperture 25 which allows the wedge-shaped profile 11 to emerge progressively above the walking plane 23 during its upward movement in the direction indicated by the arrow F.
  • the movement of the barrier is also correlated to the level 28 of water reached inside the positioning seating 15.
  • the shaped profile 21 has a closing element 34 on its top, on which an adjustable abutment element 37 is applied, for example by screwing; the insertion of the abutment element 37 to a greater or lesser depth with respect to the closing element 34 determines an adjustable end-of-travel position for the barrier.
  • an adjustable abutment element 37 is applied, for example by screwing; the insertion of the abutment element 37 to a greater or lesser depth with respect to the closing element 34 determines an adjustable end-of-travel position for the barrier.
  • there is a contrasting element 47 on the top of the wedge-shaped profile 11 which, in the maximum emergence position of the barrier, contacts the abutment element 37, causing the lifting of the barrier to stop.
  • the abutment element 37 has an adjustable position inserted more or less in depth with respect to the top of the end-of-travel element 21, it can also act as a safety release element, in the event that the wedge-shaped profile 11 were to remain blocked inside the shaped end-of-travel profile 21; the release can be achieved by screwing the abutment element 37 toward the inside, into the end-of-travel profile 21.
  • the packing elements 40 and 41 can be made in a single piece or, according to a variant, in two separate pieces, as long as the continuity of the sealing function performed by the two elements is guaranteed.
  • a centering element 42 On the opposite internal side of the end-of-travel profile 21, that is, on the side facing toward the water coming in, there is a centering element 42, which does not have a specific sealing function, but is advantageously made of a material which has characteristics of pliability and deformability substantially similar to those of the packing element 40, so as to keep the wedge-shaped profile 11 centered with respect to the end-of-travel profile 21 as the wedge-shaped profile 11 gradually rises inside it.
  • abutment and contrasting elements respectively 35 and 36, which, in the position of maximum emergence of the barrier, abut respectively against the support and contrasting element 22 and, on the side facing toward the place to be protected, against an abutment and contrasting element 33.
  • end-of-travel adjustment elements 38 and 39 are respectively assembled on the abutment and contrasting elements 22 and 33, which in a substantially similar manner to the element 37 disposed at the top of the shaped profile 21, allow to adjust the position of maximum emergence of the barrier with respect to the positioning seating 15.
  • the shaped end-of-travel profiles 21 are disposed in correspondence with the two opposite sides of the aperture 25 (as can be seen better in figs. 2 and 3 ) where the barrier 11-12 is housed, at a distance such as to allow the barrier to slide between them during its movement from the positioning seating 15 toward the outside and vice versa.
  • a cover plate 19 is associated with the aperture 25, of a shape mating to that of the aperture 25.
  • the plate 19 is hinged on one of its sides, in this case the back side, to the shaped element 26 by means of hinging elements 20 (see for example fig. 3 ).
  • the plate 19 completely closes the aperture 25 in order to create continuity between the shaped element 26 and the walking plane 23.
  • the wedge-shaped profile 11 subjected to a hydrostatic thrust of the water which progressively raises the float 12, is moved upward, it comes into contact with a portion of the plate 19 and thrusts it upward.
  • the plate 19 being hinged at one of its ends, rotates with respect to its hinged end, continuing to maintain one of its portions in contact with the surface of the wedge-shaped profile 11.
  • a first solution shown in figs. 12 and 13 , provides that each one is complete with all its components, and the respective internal walls 32 and 31 are in contact with each other, and there are respective packings to guarantee the seal.
  • the internal barriers are not provided with the respective shaped end-of-travel profiles 21, which are present only at the ends of the whole module.
  • an auxiliary passage channel 46 can be provided, which can for example be selectively closed, to allow water to reach the well 27 and then, through the discharge aperture 24, the positioning seating 15. In this way, a greater amount of water can be made to flow to the positioning seating 15 and therefore the emergence of the wedge-shaped profile 11 and the float 12 can be made more rapid.
  • the auxiliary passage channel 46 is made at a lower level than ground level (or walking level) 23, it can convey water coming from a lower level than ground level 23, and this allows the water to reach the well 27 and then, through the discharge aperture 24, the positioning seating 15. This allows to make the water flow into the positioning seating 15 before the level of water outside has reached the level of the walking plane 23, thus allowing the preventive emergence of the wedge-shaped profile 11 and the float 12. This configuration is very useful along the banks of rivers, lakes or seas.
