The invention relates to a barrier (100) suitable for installation in a sewage pipe and for preventing vermin from passing the barrier. The barrier comprising a support structure (101) with a first hinge (108) and a second hinge (109), a first shutter (102) pivotably mounted on the first hinge, a second shutter (103) pivotably mounted on the second hinge, and a locking mechanism comprising a first part (104) being a blocking mechanism, a second part (105) being formed as a protrusion. The locking mechanism is provided for keeping the second shutter (103) in a closed position, when the second shutter is tampered with by a vermin, e.g. a rat, trying to pass the barrier. This vermin barrier has the advantage of being reliable for preventing any vermin to pass the barrier, as the locking system within the barrier has a very optimal locking effect.

Method of installing equipment in the mouth of a side branch pipe in a well of a pipe installation, in particular a sewer system, comprising the following steps: a) determining the dimension of the side branch pipe, and selecting the equipment having the appropriate corresponding outer dimension; b) releasably attaching the equipment to a mounting pole c) attaching a flexible member to said equipment d) lowering the equipment down the well by means of the pole, and keeping an end of the flexible member above the well; e) inserting the equipment into the side branch pipe by means of the pole; f) tightening the flexible member along the inner wall and above the branch pipe of the well, providing a substantially vertical upwards force on the equipment, thereby fixing the equipment against an upper part of the side branch pipe; g) fixating the flexible member inside the well; h) releasing the mounting pole from the equipment, and withdrawing the mounting pole from the well.

The application concerns a device for preventing animals coming up a drain pipe. The device can be inserted into a drain pipe (10, 12) of a toilet connected to the discharge network (12) for waste water, and comprises a mobile divider (11) with with a hinge (13) at the top. The divider is able to swing in the direction of the outflow under the pressure of the flow of sewage, freeing the section for the outflow. The divider returns under the action of its own weight to a practically complete closed rest position thus preventing animals (15) coming through the discharge pipes (12).
摘要:
A barrier (100) to be installed in a sewage pipe (206, 208) for preventing rats (210) or other rodent from passing the barrier in an upstream direction of the sewage pipe, wherein the barrier comprises a support structure (104), a first shutter (101) and a second shutter (102) mounted on the support structure, wherein the profile of the edge of the second shutter is toothed to give the rats an unpleasast experience when trying to pass the shutter and the profile of the edge of the first shutter (101) is smooth..

The invention relates to a shut-off device for a waste-water inspection chamber (1) which comprises in its interior an open gutter (2) having an inlet opening (23) and an outlet opening (4) for waste-water to flow through. Said shut-off device comprises a shut-off element (5) mounted upstream of the inlet opening (23), which can be swung open by the flow force of the waste-water flow and which can be retained or released by a magnetic lock (6). Said magnetic lock (6) retains, in the shut-off position, the shut-off element (5) against the inlet opening (23) in a sealing manner and releases it when a defined water pressure is effective in the direction of flow, thereby releasing the inlet opening (23).
摘要:
A device for preventing rats from climbing, characterized in that said device made of deformable plate (1), such as metal plate, comprises a plurality of adjacently arranged deformable plates (3) and a fixing part (2) for fixing said plurality deformable plates to a pipe/rod (10) or other desired body which climbing of rats is to be prevented. Each of said deformable plates has sharp teeth and/or protrusions at its edges and has an end connected to said fixing part. And it is possible for user to deform and extend said deformable plates in various directions by using tools, so as to form a sharp construction around the contour of the pipe/rod (10), thereby preventing rats from climbing. Moreover, said fixing part is provided with a punched structure, through which fixing members such as screw, rope and steel sheet can penetrate for fixing said device or for connecting said device to other device.
