Animal e.g. wild animal, intrusion preventing device for use in tunnel for e.g. road traffic, has acoustic irradiation devices arranged in housing that is formed in middle of tunnel, and sensors detecting intrusion of animals into tunnel
摘要
<p>The device has acoustic irradiation devices arranged in a double-wall housing (1) that is formed in the middle of a tunnel. A rotary axial blower is arranged on the housing for transporting atmospheric conditions in the direction of outlets of the tunnel. Sensors (8) for detecting intrusion of animals into the tunnel are arranged in a separate housing that is attached directly to an inlet of the tunnel. Adjustable openings (13) are provided for supplying air to air channels (10), and a casing is formed in a bonnet for accommodating a reflector for flashlight signals.</p>
