Protection device for e.g. cultivated fields, has self-powered electric energy supply connected to conductive rod and conductive ring for detecting presence of livestock and triggering pyrotechnic device or sound/luminous device

The device has a self-powered electric energy supply (1) e.g. rechargeable battery, connected to a conductive rod (10) and a conductive ring (9) for detecting presence of a livestock and for triggering a pyrotechnic device (8) or sound/luminous device. The conductive ring is fixed on an internal face of a tube-shaped element (7). The conductive rod axially extends in the tube-shaped element and connected to a base (2). The base rests on a ground (3) and has tips (4) for fixing the base on the ground. Dispositif de protection à l'égard d'animaux, en particulier, de sangliers, fouines et oiseaux, destiné à les effaroucher pour les faire fuir, caractérisé en ce qu'il est portable et comporte une alimentation d'énergie électrique autonome (1) reliée à des moyens (9, 10) pour détecter la présence de l'animal aptes à déclencher un dispositif lumineux, sonore ou pyrotechnique (8).
