    摘要： The invention concerns a barrier (1) adapted for preventing backflow of sewage or for preventing vermin from passing a sewage pipe, where the barrier (1) is configured for being mounted at least partly within a sewage pipe (7), and where the barrier (1) comprises - at least one shutter (2), - a support structure adapted for having at least one shutter (2) pivot about a hinge (17) provided in the support structure, where the shutter (2) may pivot from a substantially vertical position to an angular position away from the substantially vertical position, when subject to influence by a flow of the sewage water, and where the barrier(1) is adapted to prevent the shutter (2) from pivoting in one direction, in order to prevent backlfow of sewage or to prevent vermin from passing the barrier (1) in said one direction, and wherein the barrier (1) comprises - an opening mechanism (4) arranged for opening the at least one shutter (2), a trigger (3, 21,33) configured for triggering the opening mechanism (4). A barrier (1) as described may in case of a blockage in the sewage pipe (7) open the shutter (2) based on the trigger (3, 21, 33), which triggers the opening mechanism (4). It is hereby obtained, that an element blocking the barrier (1) may be released in order to re-establish regular flow in the sewage pipe (7).

    摘要： Device in the form of a combined non-return valve and rat killer for internal fitting in a sewer pipe comprising a valve (2), which can swing between an open and a closed position, the valve (2) being able to serve as a seal against possible back-flow (B) and also as a rat killer. The valve (2) is fitted with a projection (2a) on its inner side near its lower end and when swinging down, the blow-impact of the valve with the rat (12) can kill it. The valve (2) is operated by an actuator (7), preferably in the form of a voice-coil linear motor, which is controlled by sensors in the sewer pipe. Due to a continuous flow (A) through the sewer pipe, the device will remain clean and thus functional.

    摘要： Safety mechanism for pest deterrent devices, having two separate closure members pivotally suspended in use substantially vertically, and mutually arranged at a horizontal distance, where the purpose of the two closure members is to hinder the passage of pests in one direction and allow the closure members to pivot in the opposite direction in order to allow liquid flow, where the first closure member (10) is provided with one or more slits (11, 12) which in use are substantially vertical and parallel, and where adjacent the at least one slit, a lock member (13) is arranged, which lock member projects in a plane substantially orthogonal to the plane of the first closure member in a direction away from the second closure member (20), and where the second closure member (20) is provided with a bracket (21), said bracket projecting through the at least one slit in the first closure member and where said bracket has a portion overlapping the lock members plane.
