Definitions

  • the present invention relates to an automatic cleaning device for sewerage networks.
  • the present invention aims to remedy these drawbacks by providing a cleaning device operating autonomously and without assistance, which can overcome without external intervention the various obstacles equipping the sewerage networks and which can displace a large volume of cuttings.
  • the device In practice, the device is placed on the raft of the cleaning pipe, upstream of the cuttings. In the absence of effluents, the valve is normally in the vertical position, that is to say closed. Thanks to the closed valve, the device obstructs the lower part of the cleaning duct and, therefore, creates a shutdown and storage of effluents upstream.
  • the device receives a thrust which tends to make it move forward.
  • the scraper takes care of the cuttings when it encounters them, which slows or stops the progression of the device.
  • the effluents continue to rise upstream of the valve until the latter pivots around its horizontal axis and releases the effluents. It thus generates a flood wave which displaces the cuttings deposited downstream of the device.
  • the drop in the level of the effluents allows the valve to be closed, which is ballasted at its part located below its pivot axis. The aircraft, cleared of this cuttings, can start to move again.
  • the device comprises two longitudinal walls arranged laterally and connected to the vertical uprights of the chassis comprising the valve and two pairs of lateral wings articulated around a vertical axis, one of which is fixed substantially at the height of the valve and of which l 'other is fixed to the rear of the chassis, upstream side, and at a distance from it greater than the width of the various lateral obstacles that the device is likely to encounter in a conduit.
  • the free outer edge of the wings is capable of coming into contact with the side wall of the duct and the wings are returned to this contact position by elastic means or under the effect of the thrust of the waters.
  • the lateral wings of the first downstream pair are capable of being erased by pivoting when they meet with an obstacle disposed laterally in the duct, such as a ladder.
  • the rear wings, the longitudinal walls and the transverse wall then retain the effluents. A once the obstacle has been overcome, the front wings resume their sealing position while the rear wings pass beyond the obstacle.
  • the apparatus also comprises a bottom retaining the effluents during its passage over sand pits.
  • the device is equipped with wheels and / or pads fixed to the front and to the rear of the chassis, to allow its guidance.
  • valve is advantageously mounted so as to be able to escape beyond a certain effluent thrust threshold or when meeting a stop placed for this purpose in the conduit.
  • the device is therefore taken out of service, either in the event of excessively large volumes of effluent, which could damage it, or at the place where said stopper is placed.
  • Figures 1 and 2 show an apparatus 1 for automatic cleaning of sewerage networks.
  • Figures 3 to 6 show different phases of the operating cycle of the device 1 .
  • valve 6 is normally in the vertical position, that is to say closed. Thanks to its transverse wall 5 and to its closed valve 6 , the device 1 obstructs the lower part of the curing duct and, as a result, creates and stores effluents upstream of itself (FIG. 3).
  • the device 1 receives a thrust which tends to make it advance.
  • the scraper 3 takes charge of the cuttings 15 when it encounters them, which slows down or stops the progression of the apparatus 1 (FIG. 4).
  • the effluents continue to rise along its transverse wall 5 until the valve 6 , placed at the front, pivots about its horizontal axis and releases the effluents. It thus generates a flood wave which displaces the cuttings deposited downstream of the apparatus 1 (FIG. 5).
  • the drop in the level of the effluents allows the closure of the valve 6 , which is ballasted at the level of its part located below its pivot axis.
  • the device 1 released from these cuttings 15 , can start to advance again (FIG. 6).
  • Figures 8 to 11 show the device seen from above, during the crossing of various obstacles, namely a niche 20 ( Figures 8 and 9), a pit 21 for the deposit of transported cuttings ( Figures 10 and 11) and a lateral ladder 22 ( Figures 10 and 11).
  • the lateral wings 9 of the downstream pair unfold at the level of the niche or are capable of being erased by pivoting when they meet the ladder 22 .
  • the volume of effluents located between the longitudinal walls 7 and the side wall of the duct can then escape, but the rear wings 10 , the longitudinal walls 7 and the transverse wall 5 retain the effluents.
  • the front wings 9 resume their sealing position under the effect of the above-mentioned elastic means or the thrust of the waters, while the rear wings 10 pass beyond the obstacle 20 , 22 .
  • the bottom 8 makes it possible, similarly, to prevent the flow of effluents on either side of the transverse wall 5 , when the device 1 passes over the sand pit 21 (FIGS. 10 and 11).
  • FIGS. 12 and 13 represent a system allowing the valve 6 to escape beyond a certain effluent thrust threshold.
  • the axis of articulation of the valve 6 is constituted by two fingers 25 , 26 .
  • the finger 25 has a T shape and is pivotally mounted relative to the transverse wall 5 around a vertical axis.
  • the end of the finger 26 is engaged in a housing delimited, upstream, by the wall 5 and, downstream, by an inclined wall, forming a ramp, of a stop 29 .
  • the stop 29 is movable along a screw 30 allowing its mounting on the wall 5 , which comprises a spring 31 engaged on it, coming to bear against the stop 29 on the one hand, and against a nut 32 on the other hand .
  • the stop 29 allows the end of the finger 26 to be retained against the wall 5 up to a certain thrust threshold for the effluents. Beyond this thrust, the finger 26 escapes from its housing and the valve 6 pivots, which frees the passage of the effluents.
  • the nut 32 makes it possible to adjust the thrust threshold beyond which the valve 6 is released.
  • a bent finger 33 makes it possible, by pressing against the wall 5 , to limit the pivoting of the valve 6 .
  • FIG. 14 shows an alternative embodiment of this system, allowing commissioning of the valve 6 not only in the event of a thrust of the effluents beyond a certain threshold, but also by encountering the device 2 with a stop 40 , provided for this purpose in the conduit.
  • This system comprises a pivoting assembly 41 around an axis carried by a support 42 .
  • the pivoting part 41 comprises a notch to delimit the housing for receiving the axis 26 and a finger 43 located opposite the stop 40 .
  • a helical spring 44 supported by a console 45 , normally maintains the pivoting part 41 in the position shown in FIG. 14. When the finger 43 meets the stop 40 , the part 41 pivots, which releases the finger 26 from its housing.
  • FIG. 15 represents a system of superimposed valves 6 making it possible, while keeping valves of small dimensions, to store a greater height of water.
  • the upper valve comes to rest, upstream side, against the upper part of the lower valve.
  • a seal 50 is fixed on the upper valve and rests on the lower valve.
  • FIG. 16 represents a valve 6 comprising means, such as stops for stabilizing it in a position of slight opening, allowing the effluents to pass through the gap 55 delimited between it and the bottom wall 51 . Thanks to this gap, the small transit flow in the sewerage networks can pass beyond the valve 6 . During a more substantial water supply, the valve pivots and comes to bear against the lower wall 51 . It works, then like the valve 6 described above.
  • the valve can also include means making it possible to provide a delay in closing. As shown, it may be a tank 52 open at the top, fixed to the top end of the valve 6 . This reservoir 52 , when filled with effluents, increases the weight of the upper part of the valve and delays the moment to from which it comes to close. Drain holes 53 allow this tank 52 to be emptied slowly.
  • FIG. 17 shows another alternative embodiment of the invention, in which walls 54 are provided on the upper part of the valve, so that the latter retains the stored water for a longer time at the start of the tilting.
  • a flexible flap 56 is fixed to the bottom of the valve 6 and is pressed against the lower wall 51 under the effect of the thrust of the effluents. This results in resistance to opening and greater filling upstream of the device.
  • Figures 18 and 19 show another alternative embodiment of the valve 6 which has the advantage of closing earlier in time while it is still covered with effluents. Indeed, with the valve 6 as described above, the closure takes place when the level of the effluents reaches the height of the pivot axis. However, the real efficiency of the mass of water released comes at the start of the flow. At a certain level of emptying, the released water is no longer effective in removing the cuttings and is therefore lost.
  • valve 6 shown in Figures 18 and 19, overcomes this drawback.
  • the valve 6 is articulated around an axis located approximately 2 / 5ths of the height of the valve and is surmounted by a flap 57 , which can pivot downstream and covering the upper part of the valve 6 over a height representing substantially 1 / 5th of it.
  • the valve 6 lightly ballasted at the bottom, is normally in the vertical position. It is kept in this position until the effluent level reaches flap 57 . The latter and the valve 6 then tilt completely to release the effluents.
  • valve 6 returns to the vertical position earlier than the previously described valves, which allows faster filling of the upstream part of the device and, consequently, a higher frequency of emptying of the effluents.
