Definitions

  • the invention relates to a cleaning pipe for continuous sewage pipes, which is designed as a kit according to claim 1.
  • the invention has for its object to provide a cleaning pipe of the type mentioned, with which any on-site increased effort to convert to the different sewage systems for the client is avoided.
  • the parts of the kit can be converted to a different sewage system at any time, i.e. for sewage free of faeces and for sewage containing faeces, each with a backflow risk, without this on-site changes are required. It is only necessary to remove the base cover from the shaft opening of the inspection shaft and to insert the respective assembly of the kit into the base body and to close the shaft opening with the corresponding cover, to meet the new requirements quickly and easily. This is not only inexpensive for the client and involves little work, but also for the wholesaler, for whom the inventory is simplified, since the basic body is the same for all sewage systems and only the structural units are different from one another.
  • the units are designed so that either the standard regulations applicable in the Federal Republic of Germany or the regulations in other countries are met, i.e. that either one operating lock and one emergency lock or only one operating lock for the respective sewage system is contained in the unit.
  • the backflow shut-off flap or the flaps of the second assembly are coupled to a rotary actuator so that they are kept in the open position in accordance with the DIN regulations in the operating position and can only be closed immediately in the event of a backflow.
  • the components here include insert parts that form the sealing seats for the backflow shutters, so that the tightness requirements are easily met. Basically, it would be conceivable to provide the cleaning pipe with the basic body in the basic concept with molded sealing seats, in which case no insert parts are then required. That would mean that stop surfaces for the closure flaps are firmly molded into the base body.
  • the insert parts have the advantage that they can be removed even after a long period of operation and, if necessary, replaced or cleaned with new ones.
  • backflow shutters are pivotally mounted on the insert part, preferably can be lifted out, because this enables simple and functionally reliable attachment of the backflow shutters is guaranteed, which can even be removed and do not require any special storage on the base body or on the sealing cover.
  • the feature of claim 4 is also important because it eliminates the need for additional position securing parts for the insert parts or backflow flaps, and on the other hand the removable parts are immediately accessible when the cover is removed.
  • the lid presses on the insert and covers it shoulder-like for better storage.
  • a safe function with a good sealing effect is achieved in the embodiment according to claim 5.
  • the angle lever offers a heavy weight shift for automatic closing and particularly favorable turning conditions.
  • an externally actuable mechanical and / or electromotive drive is provided in the closure cover of the first structural unit for the intended closure and, if necessary, ventilation of at least one backflow closure flap.
  • This operation which acts on the backflow valve, is intended for the so-called emergency closure, which closes arbitrarily in the event of a backflow can be. Since the drive is also able to ventilate the backflow flap after the end of the backflow situation, there is no risk that the backflow flap will stick and no longer function properly if there is a long backflow.
  • the embodiment of claim 9 is also very advantageous, which relates to a sewage system containing faeces, in which at least one backflow flap is automatically moved from the operating position into the closed position via the liquid sensor when the back pressure occurs.
  • a stump end 9 and a pointed end 7 are connected to the connecting pieces 8 and 6, for example by means of tensioning straps, in order to be able to replace and vary them.
  • a base closure lid 10 is removably attached and sealed by seals. By lifting the base cover 10 you have free access to the inspection shaft 3 and can clean the line unhindered.
  • the cleaning pipe 1 is equally suitable for sewage containing faeces and free of faeces. In the event of a backflow, however, the wastewater backing up from the draining sewer system can reach the connected devices via the cleaning pipe and exit. In order to prevent this, the cleaning pipe 1 from FIG. 1 is designed such that a backflow device for faecal-free waste water can be used as a first structural unit A according to FIG. This consists of a sealing cap 11, which corresponds with its edge dimensions to that of the basic sealing cap 10 from FIG.
  • the two backflow closure flaps 12 and 13 are at least functionally connected to the closure cover 11 in a manner that is not emphasized, that is, if necessary, molded onto it or attached to it. However, it is also conceivable to provide the two backflow shutters 12 and 13 separately from the cover 11 as separate insert parts.
  • the second backwater closure flap 13 with its drive to be explained later can be omitted, as is indicated by the dash-dotted line x.
  • the closure cap 11 would then look exactly like the base closure cap 10 according to FIG. 1 in its right half in FIG. 2.
  • the backflow closure flap 12 has a pivot axis 14 for an L-shaped angle lever 16, to which a disk-shaped flap body 17 with a peripheral seal 18 is attached.
  • the pivot axis 14 can be arranged in a bearing 15, which is either attached to the closure cover 11 or separated from it. The pivot axis 14 can be conveniently lifted out of the bearing 15.
  • the second backflow flap 13 is substantially the same as the first flap 12. Its pivot axis is arranged in a bearing 19.
  • a pressure cam 20 is formed on its angle lever, which has an overhead pressure surface and lateral ears 22.
  • a shaft with a square 24 is rotatably mounted, on which a locking cam 21 is arranged, which can cooperate with the pressure surface on the pressure cam 20 and has projections 23 which engage under the ears 22 in a certain rotational position of the square 24, to vent the backflow flap 13.
  • a hand-operated lever 25 is connected to the shaft carrying the square 24 and can be moved back and forth between the positions highlighted by a double arrow. In the position of the hand lever 25 shown in solid lines, the backflow valve 13 is locked in its closed position.
  • the backflow valve In the position of the hand lever 25 shown in dash-dotted lines, the backflow valve is 13 freely swiveling.
  • An electromotive drive could also act on the shaft carrying the square 24, so that the emergency actuation of the backflow valve 13 could also be carried out remotely.
  • the cleaning pipe 1 according to FIG. 1 is converted with a second structural unit B according to FIG. 3, which has a sealing cover 26 corresponding in outline to the basic sealing cover 10 from FIG. Furthermore, the second structural unit B included a first backflow closure flap 27 and a second backflow closure flap 28, which functionally cooperate with the closure cover 26 at a sufficient distance from one another.
  • Both backflow flaps 27 and 28 can be attached or attachable to the closure cover 26 or can also form separate insert parts which can be inserted into the inspection shaft 3 of the cleaning tube 1. Provided that appropriate sealing seats are attached or can be inserted in the cleaning shaft 3 of the base body 2, the two backflow shutters 27 and 28 then work together with these sealing seats as backflow closures.
  • the backflow valve 27 in the second assembly B according to Figure 3 has a pivot axis 29 for a pivot lever 30 which is integrally connected to a valve body 34 and contains a guide curve 31 which cooperates with a control member 32 which belongs to a rotary actuator 33, which is housed in the closure cover 26.
  • a pot-shaped, elastic sealing element 35 is attached to the valve body 34, which contains a stiffening plate 36 and defines a cavity 37.
  • the backflow shutters 27 and 28 are held in the raised position shown in FIG. 3, because according to the standard regulations the backflow shutters for sewage containing faeces must be open in the normal operating position.
  • a liquid sensor 38 is attached to the closure cover 26 and is connected via a signal line to a control device (not shown).
  • the rotary drive 33 is connected to the control device via a line 40.
  • the backflow valve 28 corresponds essentially to the backflow valve 12 and 13 of Figure 2. The only difference is that its angle lever 43 is in a positive connection via a joint 42 with a pivot cam 41, which is on the square bearing and by means of a hand lever 45th rotatable shaft sits.
  • the second backwater shut-off valve 28 with its rotary drive can also be omitted if the respective local requirements only require a single backwater shut-off valve 27.
  • the closure cover 26 would then be designed in its right half in FIG. 3 corresponding to the base closure cover 10 of FIG. 1.
  • the cleaning pipe 1 from FIG. 1 is converted by means of the first structural unit A to a backflow trap 1A for faecal-free waste water.
  • the pivot axis 14 of the backflow closure flap 12 is mounted in an upper part 47 of an insert part 48, which is pushed into the inspection shaft from above and is secured in position on a seat 50 formed there.
  • the closure cap 11 is placed on the upper part 47 from above and in this way secures the insert part 48 against being pushed out and shifting laterally.
  • the insert part 48 forms a sealing seat 49 for the backflow closure flap 12.
  • an insert 54 is inserted from above and fixed on a seat 51 formed in the base body 2, which forms a sealing seat 55.
  • the upper part of the insert part 54, designated 53, is penetrated from above the cap 11 fixed.
  • the backflow valve 13 is locked in its emergency closed position, while the backflow valve 12 can pivot freely.
  • a backwater seal 1B 'for waste water containing faeces is formed by means of the second structural unit B from a base body 2' already explained with reference to FIG. 1 with an integrally molded tip end 7 'and stump end 9'.
  • the second structural unit B is expanded by insert parts 57 and 61, which form sealing seats 59 and 62 for the two backflow shutters 27 and 28.
  • the insert part 57 is supported by a projection 58 on the bearing 50 of the base body 2 'and is secured in position on its upper part 56 by the closure cover 26.
  • the sealing seat 59 is formed here by a wide foam rubber or soft rubber seal, which cooperates excellently with the cup-shaped sealing element on the backflow flap 27, in order to ensure a perfect sealing seat even with impurities or solid parts jammed in between.
  • the insert part 61 is also fixed from above via its upper part 60 by the closure cover 26 and pressed onto a seat 51 in the base body 2 '.
  • the seats 50 and 51 are otherwise provided in the main body 2 of the cleaning tube 1 according to Figure 1 from the outset.
  • the pivot axes of the two backflow shutters 27 and 28 are mounted in the embodiment according to FIG. 5 on the upper parts 56 and 60 of the insert parts 57 and 61, respectively.
  • FIG. 5 shows the backflow device 1B 'for waste water containing faeces in its normal working position, in which the two backflow shutters 27 and 28 are held in their open position. If a backflow now occurs, the liquid sensor 38 detects this and controls the drive 33 via the control device (not shown) so that it swivels the backflow shut-off valve 27 into its closed position and pushes it back of the waste water beyond the stump end 9 'prevented.
  • the second backflow closure flap 28 can also be brought into the closed position by hand using the handle 45 (emergency closure). It would also be conceivable to operate the second backflow valve 28 remotely with an electric motor drive.
  • the individual components of the embodiments of FIGS. 1 to 5, with the exception of the shafts, drives and seals, consist of a wastewater-resistant plastic, of die-casting, of light metal or of cast iron.
