  • a coupling part designated as a whole by 1, comprises a support part 2, which engages around an electric cable 5 which leads down to the electric motor 3 of the submersible pump unit 4 with play.
  • the support part 2 consists of this Purpose of two U-shaped halves 6 and 7, which form an eyelet and enclose the electrical cable.
  • both the inside of the legs of the U-shaped halves 6 and 7 and their webs are lined with a cushion 8.
  • Axes 9 and 10 extend through bores in the webs of the U-shaped halves 6 and 7, on each of which a coupling hook 11 or 12 sits in the recess between the U-legs.
  • Each of the axes 9 and 10 projects over a leg of the U-shaped half 6 and 7 and carries a stop pin 20.
  • Rings 13 and 14 are arranged on opposite sides of the support part 2 on the axes 9 and 10, respectively.
  • Rods 15 and 16, on which counterweights 17 and 18 are arranged, extend from the rings in the radial direction. By pivoting the rods 15 and 16 carrying the counterweights from the position shown in solid lines in FIG. 1 to that which is illustrated in broken lines, the associated coupling hooks are pretensioned via the axes 9, 10.
  • the pivoting movement of the rods is limited by a recess 19 in the rings 13 and 14, in which the respective stop pin 20 engages.
  • the coupling hooks 11, 12 can be biased into the open or the closed position, as will be explained in more detail later.
  • the support member 2 is provided on the side facing away from the coupling hooks 11 and 12 with two tabs 21 and 22 which extend obliquely upwards from the opposite ends of the U-shaped halves 6, 7 Extend the middle of the support part.
  • the free ends of the tabs 21 and 22 are connected to one another by a bolt 23 which carries a lifting eye 24 which enables the engagement of a hook of the flexible tension element.
  • a roller 25 is rotatably mounted on the bolt 23 connecting the tabs 21, 22.
  • the coupling part 1 interacts with a connecting element 26 arranged on the submersible pump unit 4, namely at the upper end of the electric motor 3.
  • the connecting element 26, which is provided with a central through opening 26 ', surrounds the electrical cable 5, so that the coupling part 1, when it slides down on the electrical cable 5 to the submersible pump unit 4 into a shaft, not shown in the drawing, automatically to the connecting element 26 is led there.
  • the connecting element 26 has a mushroom-shaped shape and is frustoconical at its upward-facing end.
  • an undercut 27 is formed at the lower end of the frustoconical part of the connecting element 26, behind which the coupling hooks 11 and 12 can snap in, so that the submersible pump unit can be removed from the shaft via the flexible pulling element and the coupling part 1 carried by it with the aid of a lifting device, not shown can be lifted out or lowered into the shaft.
  • securing webs 31 and 32 are provided, which are arranged offset by 90 ° to the coupling hooks.
  • the fuse - webs sit on sheets 28 and 29, which connect the mutually directed legs of the U-shaped halves 6, 7 of the support part 2 to one another.
  • the sheets 28 and 29 are connected by fasteners 30 to the associated ends of the legs of the halves 6 and 7.
  • a laterally closable passage is created by a releasable fastening of at least one of the sheets 28 and 29, which allows the insertion of the electric cable 5 into the support part 2 in the simplest way.
  • the coupling part designated as a whole by 33, is designed as a closed bracket which encompasses the electric cable 5 and can be latched on one side behind the undercut 27 of the connecting element 26 of the submersible pump unit 4.
  • the coupling part 33 comprises a carrying element 35 which is provided with a carrying loop 34 and which, as shown in FIG. 5, has an approximately T-shaped design.
  • a bolt 36 extends through the beam of the T-shaped support element 35 and serves to fasten the free ends of the bracket 37 forming a closed eyelet.
  • a rod 38 extends from the web of the U-shaped support element 35 carrying the carrying loop 34, on which a counterweight 39 is arranged.
  • a larger supporting ring 40 is passed through the carrying loop 34.
  • either the rod 38 including the counterweight 39 can be removed from the support element, or the counterweight can be displaced on the rod.
  • a submersible pump unit is to be lowered into a deep shaft, when using the exemplary embodiment illustrated in FIGS. 1 to 3, one of the sheets 28, 29 is removed or detached on one side and the electrical cable 5 leading to the motor 3 of the submersible pump unit is inserted into the between the legs of the supporting part created slot inserted into the support member.
  • the loosened sheet is then attached again using the fastening elements. Now a hook attached to a flexible pulling element can be hooked into the support eye 24 of the coupling part 1.
  • the coupling part is then lowered onto the connecting element 26 of the submersible pump unit, and the coupling hooks 11 and 12 are engaged behind the undercut 27 of the connecting element 26.
  • the counterweights are pivoted into the position shown in FIG. 1 with dash-dotted lines, that is to say inwards, with the other end of the recess 19 resting against the stop pin 20.
  • the counterweights pretension the two coupling hooks 11 and 12 in the opening direction.
  • the submersible pump unit can now be lowered into the desired position in the shaft. Is the Submersible pump unit placed on the bottom of the shaft, and if the coupling part 1 is lowered further, the coupling hooks biased in the opening direction can disengage from the undercut, so that the coupling part 1 can be moved upwards again along the electric cable 5 with the aid of the flexible pulling element. Thereafter, the electrical cable 5 is removed from the support part 2 after loosening a sheet and the coupling part is ready for a new operation.
  • the coupling hooks 11 and 12 of the coupling part are pretensioned in the closing direction by moving both counterweights outwards into the one in FIG solid lines shown position are pivoted. Then the coupling part is led down along the electric cable 5 by lowering the flexible tension element into the shaft to the submersible pump unit. If the coupling hooks 11 and 12 reach the frustoconically shaped upper end of the connecting element 26 of the submersible pump unit, the free ends of the coupling hooks slide over the conical area of the connecting element and engage in the undercut after the lower edge has been exceeded.
  • the guide and securing webs 31 and 32 secure the coupling part against sliding off to the side. If the coupling hooks are firmly engaged in the undercut, the coupling part and the submersible pump unit connected to it can be lifted out of the shaft by lifting the flexible pulling element.
  • the bracket 37 is released from the support element 35 by pulling out the bolt 36 and placed around the electric cable of the submersible pump unit to be lowered and inserted again of the bolt 36 in the support member 35 connected to the coupling part 33.
  • a hook of a flexible tension element is inserted into the ring 40 of the coupling part and the bracket 37 is locked behind the undercut of the connecting element on the submersible pump unit.
  • the beam of the T-shaped support element 35 is supported on the side of the frustoconical upper end of the connecting element 26 opposite the latching of the bracket 37.
  • the rod 38 For biasing the coupling part in the opening direction, the rod 38 must be inserted into the support element 35, so that the counterweight 39 endeavors to disengage the bracket 37 from the undercut of the connecting element as soon as no more tension is exerted on the support element 35.
  • the submersible pump unit can now be lowered into the shaft by lowering the flexible tension element.
  • the counterweight 39 lifts the bracket 37 out of the undercut, since the counterweight pivots the coupling part 33 around the ring 40 in the carrying loop 34. Now the flexible pulling element can be lifted, the bracket surrounding the electrical cable moving upwards along the cable.
  • the coupling part 33 is lowered along the electrical cable into the shaft along the electrical cable after the electrical cable has been inserted into the eyelet 37 and after the rod 38 with the counterweight 39 has been removed from the support element 35 37 slides over the conical area of the connecting element, whose lower edge exceeds and engages in the undercut. Since the weight of the bracket 37 tries to pivot the coupling part 33 in such a way that the lower part of the bracket 37 rests firmly on the connecting element 26, the bracket 37 cannot detach from the connecting element even when the submersible pump unit is lifted out of the shaft. The submersible pump unit can thus be safely moved up from the deep shaft.
