    DK 2019 00216 A1 Method for positioning equipment in the bottom part of a manhole in a sewage system, and system therefor Field of the Invention The present invention relates to the field of equipment for use in sewage systems. Background of the Invention A general problem when using equipment for different purposes in a manhole being part of a sewage system is that it is difficult to fasten the equipment within the manhole without having to enter the manhole itself. Due to the inherent danger of working in a manhole, this operation usually requires the presence of another person on the surface as a safety precaution. Equipment, such as sensors or means for killing rodents, must be very precisely positioned in order to function properly. Fastening means must not prevent the manhole cover from being properly positioned in the manhole cover frame. Furthermore, some types of sensors are sensitive to vibrations that may travel from the walls of the manhole via the fastening means to the sensor, thereby resulting wrong results, such as a falls positive registration of the triggering of a rodent trap. Vibrations generated when a vehicle passes over the cover plate is a well-known problem that may cause fastening means to lose its grip in the manhole. If the manhole, for some reason, must be accessed while the equipment is mounted, it is also desirable to be able to remove equipment without too much trouble.
    Object of the Invention The objective of the present invention is to provide a method that solves or at least alleviates some of the above problems.
    , DK 2019 00216 A1 Description of the Invention A first aspect of the present invention relates to a method for positioning equipment in the bottom part of a manhole in a sewage system comprising the steps of: - determining the diameter of the upper part of a manhole below the manhole cover frame in a sewage system, and selecting a ring-shaped resilient spring body having an appropriate corresponding diameter to resiliently fit inside said upper part of a manhole; wherein the spring body has a first end and a second end, each provided with a lip extending inwardly towards the centre of the ring shape, and together defining an opening in the ring shape; wherein an actuating means is suspended between the lips and configured for increasing the diameter of the spring body by increasing the opening between said lips; - engaging the ring-shaped resilient spring body with the inner walls of the upper part of a manhole below the manhole cover frame; - operating the actuating means to increase the diameter of the spring body, thereby firmly fastening the said ring-shaped resilient spring body with the inner walls of the upper part of a manhole; - attaching one end of a support line to equipment for use in the bottom part of the manhole; - attaching a support line fastening means to the inner face of the spring body, said support line fastening means optionally being pre-attached to the inner face of the spring body; - mounting the support line to the support line fastening means; - lowering the equipment down to the bottom part of the manhole; - tightening the support line, thereby providing a substantially vertical upwards force on the equipment and attaching the other end of the support line to the support line fastening means.
    The determination step may obviously be performed by a simple visual inspection of the diameter of the upper part of the manhole or by using any suitable tool to determine the actual diameter. The ring-shaped resilient spring
    3 DK 2019 00216 A1 body may exist in different sizes and may also be configured to fit different diameters of manholes if it comprises a ring size adjustable part. A preferred example of such a ring size adjustable part is where one, or both, of the lips are slidable connected to the ends of the spring body. The end of the spring body may comprise a track or a slit adapted for the lip to move in, thereby being slidably connected thereto. The opposite scenario may also be possible, where the lip comprises a track or a slit adapted for the end of the spring body to move in. The ring size adjustable part may also comprise a fastening means adapted for releasably fastening the lip to the spring body.
    The spring body has a first end and a second end, each provided with a lip extending inwardly towards the centre of the ring shape, and together defining an opening in the ring shape. An actuating means is suspended between the lips and is configured for increasing the diameter of the spring body by increasing the opening between said lips. A preferred example of such an actuating means is a threaded rod with a threaded nut mounted thereon, preferably a wing nut, i.e. a nut with wings that provide a grip for the thumb and finger. One of the two ends of the threaded rod is fastened to one (the first lip) of the two lips, and the other end is slidably connected to a hole or slit in the other lip (the second lip). A hollow cylinder is positioned around the part of the threaded rod being opposite to the (wing) nut. The cylinder has a larger diameter or width than the hole or slit in the second lip. Thereby, by turning the nut, the cylinder is forced towards the second lip, thereby slightly increasing the diameter of the spring body. Hence, the ring-shaped resilient spring body is first engaged with the inner walls of the upper part of a manhole below the manhole cover frame, and then the actuating means is operated to increase the diameter of the spring body, thereby firmly fastening the said ring-shaped resilient spring body with the inner walls of the upper part of a manhole. In this embodiment, the ring size adjustable part preferably comprises a fastening means adapted for releasably fastening the lip to the spring body. The fastening means will be released during the step of engaging the ring-shaped resilient spring body with the inner walls of the upper
    1 DK 2019 00216 A1 part of a manhole below the manhole cover frame. The fastening means is then fastened. Then the nut is rotated thereby forcing the cylinder towards the second lip to slightly increase the diameter of the spring body, and the fastening means is tightened to secure that the spring body will stay in place.
    As the spring body is properly secured, the next step is to attach one end of a support line to equipment for use in the bottom part of the manhole. Any type of equipment may be used with this method, but it is especially developed for rat traps, rat barriers, a sewage water flow meters, and the like.
    In one or more embodiments, the equipment is selected from the group consisting of a rat trap, a rat barrier, a sewage water flow meter, a sewage water level meter, means adapted for scaring rats, a wireless transmitter unit, and combinations thereof.
    Then a support line fastening means is attached to the inner face of the spring body. In some embodiments, the support line fastening means is pre-attached to the inner face of the spring body. However, it is preferred that it is attached after the spring body has been secured, as an uneven weight on the spring body makes it more difficult to handle during the fastening step. The support line may then be mounted to the support line fastening means, and the equipment is lowered down to the bottom part of the manhole. Finally, the support line is tightened, and the other end of the support line is attached to the support line fastening means.
    The support line has two purposes. It is used as means for lowering the down to the bottom part of the manhole. Thereby, no personnel need to enter the manhole during the installation. Furthermore, the supporting line is used to retain the equipment at a desired position. The supporting line may e.g. be a rope or a wire.
    DK 2019 00216 A1 The support line fastening means may have different configurations depending on the shape of the manhole, and/or on the specific equipment. In one or more embodiments, the method further comprises the step of attaching 5 a support line guide means to the support line fastening means and adjusting the support line guide means such that the support line is positioned along the inner wall of the well, or at least such that the support line is positioned close to the inner wall of the well.
    Some manholes are provided with a cone-shaped upper part. In this situation, a support line guide means is attached to or arranged on the support line fastening means. The support line guide means may be configured as an elongate member. The support line guide means is preferably pivotably attached to or arranged on the support line fastening means in a pivot point between the ends of the elongate member. The tip of the elongated member may be adapted to receive said support line. The opposite end of the elongated member, relative to the tip, may be provided with a locking member, which is configured to lock the elongate member in a determined angle relative to the support line fastening means, such that this configuration may be used for manholes having a larger diameter down hole and/or provided with a cone adjacent the upper end of the manhole. Thereby, the support line may be brought into contact with, or at least close to, the wall of the manhole. The tip may comprise a recess or a hole or channel adapted for receiving the support line. In the two latter cases the support line needs to be threaded before the end of the guide line is fastened.
    In one or more embodiments, a support line guide means is pivotally attached to or arranged on the support line fastening means. Preferably, the support line guide means comprises an elongated member pivotally attached to or arranged on the support line fastening means. The tip of the elongated member may be adapted to receive said support line.

    In one or more embodiments, the method further comprises the step of inserting the equipment into the mouth of a side branch pipe in the bottom part of the manhole by means of a mounting pole. Especially rat traps may advantageously be mounted in the side branch pipe, thereby preventing the rats from passing the trap without activating the trigger mechanism. In one or more embodiments, the step of tightening the support line is performed such that a part of the weight of the equipment is carried by the support line.
    In one or more embodiments, the equipment comprises a wireless communication unit, and a monitoring unit; wherein the wireless communication unit is configured for receiving monitoring data from the monitoring unit and configured for transmitting said received monitoring data. In this situation, the method may further comprise the step of mounting a wireless relay configured communicating with said wireless communication unit to either a) the inner face of the spring body, or b) to the support line fastening means, or c) to the support line guide means; wherein the wireless relay is configured to receive the monitoring data from said wireless communication unit and to retransmit the received monitoring data. A second aspect relates to a mounting system for positioning equipment in the bottom part of a manhole in a sewage system, the mounting system comprising: - a ring shaped resilient spring body sized and configured for resiliently engaging with the inner walls of the upper part of a manhole in a sewage system; the spring body having a first end and a second end, each provided with a lip
