Definitions

  • an arrangement including an eccentrically pivoted weight, which is turnable around a point of suspension so that it, because of the application of its mass against a guide and an outlet pipe holds a pump unit against the outlet pipe. Further means are provided to enable removal of the weight from contact with the guide and pump unit to enable removal of the pump unit from contact with the outlet pipe.
  • FIGURE shows an arrangement of elements in accordance with an embodiment of the invention.
  • 1 and 2 stand for a pump unit and an outlet pipe respectively, and 3 and 4 stand for their coupling flanges.
  • 5 Stands for a guide .means arranged on the pump unit 1, which means is meant to slide along the guide 6 when raising or lowering the pump unit.
  • 7 Stands for a clutch at the guide means 5
  • 8 a turnable weight
  • 9 the pivot suspension of the latter
  • 10 a projection on the same
  • 11 an elongated tensionable operation means for the weight.
  • the locking device works as follows:
  • the pump unit 1 When the pump unit 1 is lowered to its working position, it is guided by the guide means 5 which partly encircles the guide 6. In order to secure better guidance, it is common to use two guides, of which only one can be seen in the drawing.
  • the clutch 7, arranged on the guide means 5 will grip over the flange 3 of the outlet pipe 2, so that the coupling units, flanges 3 and 4 automatically come into the right position relative to each other.
  • a weight 8 has been arranged in conjunction with the guide means 5, which weight is turnable around a pivot indicated by a bolt 9.
  • the weight 8 is provided with a projection 10, which is formed like a cam with a varying radius. Because of its eccentric suspension, the weight will turn around the bolt 9 in a direction shown by the arrow in the FIGURE, which means that the projection 10 will be pressed against the guide 6.
  • the weight 8 is turned in the opposite direction by help of the operation device 11, which can be operated from a point above the water surface.
  • the projection 10 then losses its contact with the guide 6 and the pump unit can be lifted up in the usual way.
  • the invention disclosed is a locking device for a submersible pump unit which is simple and strong and easy to operate and which is not affected by pollutants which occur in the pumped water.
  • a locking device for submersible pumps arranged as a releasable connection between a pump unit and a generally submerged outlet pipe comprising guide means attached to a pump unit, said guide means during lowering of a pump including means adapted to slide along a substantially vertical guide, a weight eccentrically suspended on the guide means, said weight being turnable around its point of suspension so that due to the effect of gravity it endeavors to turn around this point, said weight including a projection which,
