Definitions

  • the invention relates to a method for acoustically reporting drowning people in swimming pools according to the preamble of claim 1.
  • the invention is therefore based on the object of providing a method and a device for carrying out this method in which a reliable alarm triggering when a drowning person falls into the swimming pool is ensured and a false alarm is excluded.
  • the circuit arrangement shown as a block diagram for acoustic notification of drowning people in swimming pools consists of a switching element 1 fixedly arranged in the swimming pool below the water surface, which is connected to an alarm device 2, which is preferred by an accumulator 3 Operating voltage of 9 volts is fed at a quiescent current of zero amperes, the accumulator 3 being rechargeable by solar cells 4 during the day.
  • a signal horn 5 is connected to the alarm device 2 via a relay (not shown in the drawing). When an alarm is triggered, the relay switches and signal horn 5 triggers an acoustic alarm.
  • the alarm device 2 with the horn 5 is outside the pool, for. B. at the edge of the pool.
  • a transmitter 6 is connected to the alarm device 2 via a cable connection, from which the alarm signal is transmitted to a remote receiver 7 in the event of an alarm, the alarm signal beforehand from a preamplifier 8 is reinforced.
  • a further alarm device 10 with a signal horn 11 is connected to the receiver 7 via a pulse converter 9.
  • the circuit arrangement described above can be used with ice-free water in the swimming pool 19.
  • a specially encapsulated microphone 12 is hung in the ice-free water, which picks up the noise caused by a person breaking into the ice under or on the ice, this in of a subsequent electronic device processed in terms of signals and fed to alarm devices 2 and 10 in the event of an alarm.
  • the sinusoidal vibration generated when a body falls into the frozen swimming pool Microphone 12 downstream pulse converter 13 converted into a rectangular pulse, which triggers the alarm device 2 via a relay, not shown in the drawing.
  • the alarm signal is transmitted via the transmitter 6 to the remote receiver 7 to the alarm device 10 which triggers the alarm.
  • An infrared device, an ultrasound transmitter or a radio device can advantageously serve as the transmitter.
  • the receiver 7 can also be connected to an existing house alarm device or to an independent alarm device installed in the car or in a caravan. It is also advantageous if the receiver 7 is a microphone, not shown in the drawing, which is set up in a room for room monitoring of unwanted people (intruders).
  • the receiver 7 can be connected, for example, to a car battery with an operating voltage of 12 volts.
  • the receiver 7 can also be connected to a smoke detector, temperature sensor or water detector.
  • the encapsulated microphone 12 is replaced by the switching element 1.
  • the watertightly encapsulated switching element 1 is preferably arranged on the rear side of a flap 16 rotatably mounted via an axis 15 at the outlet of a funnel-shaped housing 14 perpendicular to the water surface.
  • the switching element 1 can be a mercury switch.
  • the wave movement caused when a body falls into a swimming pool 19 is increasingly absorbed by the funnel 14 and causes the flap 16 to rotate, as a result of which the mercury switch 1 switches the alarm device via a cable connection 17 connected to the alarm device 2 and the signal horn 5 triggers an acoustic alarm .
  • the one in the swimming pool below the water surface in a corresponding Deeply immersed funnel 14 is attached to an angled linkage 18, which is arranged with its one angular part 18a on the pool edge 19a.
  • a false alarm which is triggered by strong wind or branches falling into the pool, is excluded by the arrangement of the switching element 1 below the water surface.
