Definitions

  • the present invention relates to a device for detecting the various water leaks in non-accessible installations, as well as accidental flooding of cellars or attics.
  • Water leaks in non-accessible installations can lead to various drawbacks, for example: if a water leak appears in a built-in siphon, it is not noticed until the water has penetrated the ground and passed through the ceiling.
  • the device according to the invention makes it possible to avoid drawbacks of this kind. It is placed below the point where a water leak can take place and, thanks to an alarm system, it sends a signal to a receiving station warning that the leak has started.
  • the operation of the device according to the invention is based on the principle of electrolytic dissociation ...
  • the device is a switch which reacts to the presence of water, independently of the general conditions of humidity and temperature.
  • the sheet placed between the sheets plays the role of a dielectric and prevents the circuit between the conductors from closing; if however, water contacts the surface of the perforated sheet, it penetrates into the holes, wets the sheet and thus causes the dissociation of the NaCl which, acting as an electrolyte, allows electrolysis between the two sheets (electrodes) .
  • the electrical circuit between the two conductors is thus closed and a control signal is sent for an auxiliary circuit.
  • the tempered paper is changed by raising one of the two aluminum plates.
  • the device described in said document aims mainly to detect the presence of water inside a car.
  • the object of the present invention is the creation of a device for detecting water leaks in installations where the leaks are not easily controllable due to the placement of the installations. Said object is achieved thanks to the implementation of the features presented in claim 1.
  • the device comprises a flexible sheet made with a flexible, water-repellent or impermeable material, such as for example a water-repellent fabric preserving moisture, a layer of a hydrolizing substance and two flexible metal sheets and thin spread in parallel on said substance.
  • An electrical conductor is connected to each metal sheet.
  • Said ply may, according to another characteristic of the invention, be sectioned into several parts, each of which constitutes an independent switch.
  • the device can thus be arranged on different lengths and widths.
  • a hydrolizing substance 2 such as NaCl.
  • Two metal sheets 3 are spread in parallel on said hydrolizing substance 2.
  • Contact terminals 6 pass through the assembly, each terminal being connected, both with a metal foil 3 and with a conductive wire 7.
  • the conductive wires 7 lead to a signaling device, not shown (being conventional).
  • said contact terminals 6 consist of press studs; in this case the ends of the conducting wires 7 are also provided with press studs (male or female).
  • the device shown in Figure 1 can be sectioned into several parts, each having a contact terminal on each metal sheet. Each part in Figure 2 thus constitutes an independent breaker.
  • the device can be arranged, as required, on different lengths and widths.
  • each of the two metal sheets 3 can be perforated or replaced by two flexible metal grids placed in parallel. This embodiment allows faster dissociation of substance 2.
  • the device can be used to detect water leaks in installations that are inaccessible due to their placement. We can install it in advance under a roof to be built or under any other construction likely to have water leaks in the future such as a cellar or an attic, or even a water station with a very narrow space.
  • the device can also be placed in a garden in order to be warned in the event of a rain beginning and thus be able to take certain precautions.
  • Particularly interesting applications for the installation of the device are, for example: under the sanitary facilities of bathrooms in hotels, buildings or factories.
