Gegenstand der Erfindung ist eine mit einem Ultraschallsender ausgestattete Schutzeinrichtung für Fluren oder Gebäude gegen Beschädigungen durch Vögel, Insekten oder dergleichen, die sowohl energiesparend als auch schonend für Objekte, die allenfalls durch Ultraschall gefährdet werden könnten, ausgebildet ist.The invention relates to a protective device for corridors or with an ultrasonic transmitter Buildings against damage from birds, insects or the like, which are both energy-saving and gentle is designed for objects that could possibly be endangered by ultrasound.

Ein wesentliches Problem beim Betrieb solcher Geräte stellt jedoch die Energieversorgung dar, denn ein wirksamer Einsatz derselben erfordert eine energiereiche Schallabstrahlung. Flurschutzgeräte, die bei Saaten und Kulturen eingesetzt werden, sind meistens mit einer Batteriespeisung versehen, die sich bei hoher Energieentnahme relativ rasch erschöpft. Bei Geräten, die zum Schutz von Gebäuden dienen, bereitet eine Speisung aus dem Netz keine besonderen Schwierigkeiten; es wird jedoch in manchen Fällen eine Beschädigung der Gebäudefassaden durch intensive Beschallung befürchtet.A major problem in the operation of such devices, however, is the energy supply, because it is an effective one Use of the same requires high-energy sound radiation. Ground protection devices that are used in the case of seeds and cultures are used, are usually provided with a battery supply, which is at high energy consumption exhausted relatively quickly. For devices that are used to protect buildings, a supply is provided from the network no particular difficulties; However, in some cases it will damage the building facades feared by intense sound.
Die Erfindung hat sich aus diesen Gründen die Aufgabe gestellt, den Energieabfall der Ultraschallsender von Schutzeinrichtungen gegen Schädlinge der beschriebenen Art dadurch zu reduzieren, daß der Ultraschallsender mittels einer Um schälvorrichtung bedarfsweise entweder auf eine hohe, der Vertreibung dienende oder auf eine geringe, der Fernhaltung dienende Abstrahllei-For these reasons, the invention has set itself the task of reducing the energy loss of the ultrasonic transmitter from Reduce protective devices against pests of the type described in that the ultrasonic transmitter by means of an order peeling device as required either to a high level that serves to expel or to a low level that serves to keep at a distance
stung einstellbar ist. 'power is adjustable. '
Die Erfindung geht aus von der Erfahrung, daß Tiere einer bestimmten Gattung gewisse Schallfrequenzen schmerzhaft empfinden und diese besonders dann fürchten, wenn sie diese Frequenz einmal mit besonders hoher Intensität gehört haben. Es erzeugt dann schon ein Schall geringer Intensität, jedoch mit dieser Frequenz,'eine abschreckende Wirkung. Demgemäß genügt es, den Schall mit der abschreckendenThe invention is based on the experience that animals of a certain species are painful at certain sound frequencies feel and fear them especially when they hit this frequency with particularly high intensity have heard. It then already generates a sound of low intensity, but at this frequency, 'a frightening one Effect. Accordingly, it is sufficient to mix the sound with the deterrent

Frequenz nur kurzzeitig mit hoher Intensität abzustrahlen, bis alle Tiere aus der Beschallungszone vertrieben sind, worauf die abschreckende Frequenz nur mehr mit geringer Intensität abgestrahlt werden muß, um diese Tiere von den beschallten Objekten fernzuhalten.Emit frequency only briefly with high intensity, until all animals have been driven out of the sound zone, whereupon the deterrent frequency only continues with low intensity must be emitted to keep these animals away from the sonicated objects.
Dieses Verfahren ist sowohl für Ultraschallsender mit einer einzigen Frequenz geeignet als auch für solche, die in an sich bekannter Weise mehrere Frequenzen gleichzeitig abstrahlen, um eine gewisse Breitenwirkung zu erzielen.This method is suitable for ultrasonic transmitters with a single frequency as well as for those which in a manner known per se emit several frequencies at the same time in order to have a certain broad effect achieve.
Die Umschaltung des Ultraschallsenders von hoher Intensität auf geringe und umgekehrt kann nach einem weiteren Merkmal der Erfindung entweder programmgesteuert erfolgen, nämlich dann, wenn das Verhalten der Tiere im vorhinein abschätzbar ist, oder aber in Abhängigkeit von Einrichtungen gesteuert werden, die die Anwesenheit von Schädlingen in dem zu schützenden Raum feststellen. Als solche eignen sich beispielsweise Lichtschranken oder aber auch Annäherungsschalter die insbesondere auf Veränderungen elektrischer oder elektromagnetischer Felder ansprechen.Switching the ultrasonic transmitter from high intensity to low levels and vice versa, according to a further feature of the invention, can either be program-controlled take place, namely when the behavior of the animals can be estimated in advance, or in dependence controlled by facilities that detect the presence of pests in the area to be protected determine. Light barriers or proximity switches, for example, are suitable as such respond in particular to changes in electrical or electromagnetic fields.
