Storm drain (2) comprising a device (1; 10) for enabling amphibians to release themselves from the storm drain (2), said storm drain (2) having a top side (8) with an entrance for receiving rain water in said storm drain (2) and a bottom side (7) that is connected to a sewer pipe, a sewer lid (14) being positionable between a first position for closing of an entrance to said sewer pipe and a second position for at least partly providing access to the entrance of said sewer pipe. The storm drain (2) is characterized in that said device (1; 10) for enabling amphibians to release themselves from the storm drain (2) comprises a plate-shaped grid having recesses (4) for providing a holding surface to said amphibians, extending from a position near said bottom (7) to said entrance at the top side (8) of said storm drain (2).
摘要:
A device for preventing animals coming up through drain pipes, the device comprising a siphon (2) having a sphere arranged therein such that without any water coming from upstream the sphere (9) closes an inlet (5) to the siphon.

A bug-proof and odor-proof drainage device (A) includes a cover (1), a base (2), and a connecting pipe (6) connecting plural bases (2) of different bug-proof and odor-proof drainage device (A). The cover (1) has plural draining holes (11) arranged in intervals. A capping (12) is disposed on the bottom surface of the cover (1). The base (2) has a through hole (21) surrounded by a wall part (22) extending upward. The base (2) is embedded in floors of bathrooms and kitchens and connected to a draining pipe (5) through the through hole (21) and also connected to different bases (21) by the connecting pipe (6). Water flows into the base (2), and then circuitously sinks to flow over the wall part (22) and rises along the wall part (22), thereby flowing into the draining pipe (5) from the through hole (21), such that a portion of water is stored within the base (2) for preventing bugs and odor from entering through the draining holes (11).
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:
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.
摘要:
A rat trap (1) which comprises a plate (2) with a first side and a second side and with a number of through-going openings from the first to the second side. The trap has a number of spikes (3) secured to an anchoring plate (4) arranged on the top face of said plate and wherein each spike is adapted to the individual openings in the plate to the effect that a spike is able to slide through the plate. The plate (2) has an infrared sensor adapted to detect the presence of a rat within the reach of the spikes. The rat trap further comprises a withdrawal mechanism which, following a given period of time, withdraws the spikes through the openings in the plate whereby the rat spiked by one or more spikes (3) is released.
摘要:
A method and a console for the installation of powered equipment (1) in front of a sewer pipe opening (41) in a sewer shaft (50), the method comprising the steps of, selecting resilient tubular member (40) comprising a console adapted for mounting the powered equipment, the resilient tubular member having, in its unstressed state, an outer radius which slightly exceeds the inner radius of the sewer pipe opening, mounting. the powered equipment on the console positioning the resilient tubular member in front of the sewer pipe opening and compressing the resilient tubular member to obtain an outer radius being smaller than the inner radius of the sewer pipe opening, Inserting into the sewer pipe at least a part of the resilient tubular member, so that the console with the powered equipment extends inside the sewer shaft, releasing the compression of the resilient tubular member (40), so that it expands to engage with the inside of the sewer pipe opening (41).
