Abstract

Device which automatically closes the main gas tap or the main gas valve (4) in a building during seismic earth shocks and in the event of smoke and/or fire. The signals of the corresponding sensors (1, 7) are conducted via an electronic control (2) to a solenoid or electric motor (3) which interrupts the gas supply. The respective operating state is indicated optically and the functioning of the device can be checked by means of button pressing. <IMAGE>

Beschreibung description

Bei Erdbeben entstehen nachfolgend oft Hausbrände, weil die Erd- oder Stadtgasleitung im Ge-bäudeinnern zerstört wird und das ausströmende Gas entzündet wird. Die Erfindung soll den Feuerausbruch verhindern helfen. In the event of an earthquake, domestic fires often occur because the natural gas or city gas pipeline inside the building is destroyed and the escaping gas is ignited. The invention is intended to help prevent the outbreak of fire.

Der unter Patentanspruch 2 erwähnte und in der Zeichnung als 1 dargestellte Erschütterungssensor gibt bei genügend grossen Erdstössen kurzfristig ein Signal an die elektronische Steuerung 2, indem das mit dem keilförmigen Ende innerhalb eines Ringes hängenden Pendels 6 letzteren kurz berührt und so durch die Elektronik und das Solenoid oder den Elektromotor 3 das Schliessen des Hauptgashahns oder -ventils 4 auslöst. The vibration sensor mentioned under claim 2 and shown in the drawing as 1 gives a short signal to the electronic control 2 when the earthquakes are sufficiently large, by briefly touching the pendulum 6 hanging with the wedge-shaped end within a ring and thus by the electronics and the solenoid or the electric motor 3 triggers the closing of the main gas valve or valve 4.

Die Empfindlichkeit des Sensors 1 wird mit der Höhenverstellung des Pendels mittels der Stellschraube 5 eingestellt. The sensitivity of the sensor 1 is adjusted with the height adjustment of the pendulum using the adjusting screw 5.

Bei Wahrnehmung von Rauch oder Feuer durch externe Rauch- und/oder Feuersensoren 7, welche mit der elektronischen Steuerung verbunden sind, wird der Hauptgashahn oder das Hauptgasventil in der gleichen Art geschlossen (siehe Patentanspruch 1). When smoke or fire is detected by external smoke and / or fire sensors 7, which are connected to the electronic control, the main gas tap or the main gas valve is closed in the same way (see patent claim 1).

Die Speisung des den Hauptgashahn oder das -ventil schliessenden Solenoids oder Elektromotors und die Speisung der elektronischen Steuerung erfolgt mittels eines Gleichstromakkus 8, welcher durch ein am Haus-Wechselstromnetz stehenden Ladegerät 9 immer auf genügender Spannung gehalten wird, um die Vorrichtung auch bei Ausfall des Wechselstromnetzes funktionstüchtig zu halten. The supply of the solenoid or electric motor closing the main gas tap or valve and the supply of the electronic control takes place by means of a direct current battery 8, which is always kept at a sufficient voltage by a charger 9 connected to the house alternating current network, in order to keep the device even in the event of failure of the alternating current network to keep it functional.

Die Betriebsbereitschaft wird mittels einer LED (Kontrollampe) angezeigt. Eine weitere LED zeigt eine Störung des Systems an. Die Vorrichtung kann mittels einer TEST-Taste überprüft werden, ein Öffnen des geschlossenen Hahns oder Ventils erfolgt durch die RESET-Taste. The operational readiness is indicated by an LED (control lamp). Another LED indicates a system malfunction. The device can be checked by means of a TEST button, the closed tap or valve is opened by the RESET button.

Die Vorrichtung wird an einer festen Hauswand installiert und der Erschütterungssensor 1 danach genau justiert. The device is installed on a fixed wall of the house and the vibration sensor 1 is then precisely adjusted.

Elektromotors (3) schliesst resp. schliessen und die Stromversorgung der Vorrichtung durch einen Akku (8) sichergestellt wird, welcher mit einem am Haus-Wechselstromnetz stehenden Ladegerät (9) auf genügender Spannung gehalten wird.1. Device for the automatic closing of a main gas tap or a main gas valve in a building in the event of seismic earthquakes, characterized in that a sensor (1) that registers the earthquakes and a smoke and / or fire sensor (7) is or are present, whereby the Earthquake registering sensor (1) resp. the smoke and / or fire sensor (7) via an electronic control (2) the main gas valve or the main gas valve (4) by means of an electromagnetic solenoid, respectively. Electric motor (3) closes or close and the power supply of the device is ensured by a rechargeable battery (8) which is kept at a sufficient voltage by means of a charger (9) connected to the house's alternating current network. 2. Sensor für eine Vorrichtung nach Patentanspruch 1, welcher bei seismischen Erdstössen ein Signal an die elektronische Steuerung (2) abgibt, dadurch gekennzeichnet, dass ein an einer Spiralfeder aufgehängtes Pendel (6) mit konischer Spitze bei einer Bewegung der Vorrichtung derart in Schwingung gerät, dass kurzfristig ein die konische Spitze des Pendels (6) umgebender Ring mit diesem in Berührung kommt und dieses Kurzschlussi-gnal an die elektronische Steuerung (2) weitergibt, wobei die Empfindlichkeit des Sensors mittels einer Stellschraube (5) über der Spiralfeder eingestellt werden kann.2. Sensor for a device according to claim 1, which emits a signal to the electronic control (2) in the event of seismic earthquakes, characterized in that a pendulum (6) suspended on a spiral spring with a conical tip starts to oscillate when the device moves that a ring surrounding the conical tip of the pendulum (6) briefly comes into contact with it and transmits this short-circuit signal to the electronic control (2), the sensitivity of the sensor being able to be set by means of an adjusting screw (5) above the spiral spring . 55 1010th 1515 2020th 2525th 3030th 3535 4040 4545 5050 5555 6060 6565 22nd
