Animal e.g. wild boar, scaring device for e.g. farmhouse, has detection unit to detect passage of animal between two adjacent stakes, where unit controls closure of electric supply circuit and triggers firing and explosion of detonator

The device has stakes (1-3) driven in soil (4) near a to-be-protected area e.g. farmhouse, where each stake supports a detonator (5). An electric power source is connected to the detonator, and a switch opens and closes an electric supply circuit of the detonator. A detection unit detects passage of...

Zusammenfassung:The device has stakes (1-3) driven in soil (4) near a to-be-protected area e.g. farmhouse, where each stake supports a detonator (5). An electric power source is connected to the detonator, and a switch opens and closes an electric supply circuit of the detonator. A detection unit detects passage of an animal between two adjacent stakes by using a wire (6) or a sensor e.g. infrared sensor. The detection unit controls closure of the electric supply circuit and triggers firing and explosion of the detonator. The stakes are interconnected with each other by the wire. 1-Dispositif pour effaroucher des animaux tels que sangliers chevreuils , renards et analogues...comprenant des piquets ( 1,2,3), placés à proximité d'une zone à protéger , chaque piquet supportant au moins un pétard (5) , une source d'alimentation électrique raccordée audit pétard , un interrupteur pour ouvrir et fermer le circuit d'alimentation électrique du pétard (5) , des moyens étant prévus pour détecter le passage d'un animal entre deux piquets voisins (1,2,3), ces moyens de détection étant aptes à commander la fermeture du circuit électrique et déclencher la mise à feu et l'explosion du pétard 5 .
