Definitions

  • a pump apparatus for catch basins or sumps includes a pump unit supported for up and down movement on fixed guide means.
  • the pump having a tubular outlet, tilts at an angle when being raised or lowered, and the outlet is vertically aligned with the inlet opening of a discharge pipe.
  • the pump outlet engages the discharge pipe opening as the pump unit is lowered, it is automatically forced into a full coupling position by the weight of the pump unit.
  • This invention relates to apump apparatus for catch basins and the like and more particularly it relates .to a pump unit that will automatically couple with the open end of a discharge pipe when .lowered into the catch basin.
  • catch basins are commonly used in sewage systems where temporary storage of the effluent must be provided before it can be fed into the main sewage outlet conduit or raised to a different level before being directed to a processing plant.
  • Submersible pumps have long been in these catch basins to remove the collected effluent when required.
  • One object of the present invention is to provide a pump apparatus of the aforesaid type for use in a catch basin or sump that enables a pump unit to couple into a fluid tight connection or uncouple with ease and efficiency when lowered and raised.
  • Another object of the present invention is to provide a pumping apparatus for sumps or catch basins comprising an automatic coupling pump unit that is particularly well adapted for ease and economy of manufacture, that is particularly reliable, durable and also easy to service and maintain.
  • Another object of the present invention is to provide a pumping apparatus for sumps or catch basins that will function with positive action by gravity force only and will not be rendered inoperative by the presence of suspended solids in the effluent or by relative high viscosity factors.
  • Yet another more specific object of my invention is to provide a pumping apparatus for catch basins or sump wherein a pump unit comprised of a motor and a pump is pivotally mounted and also movable upward and downward on vertical guide means fixed in the catch basin so that as'the unit is raised or lowered it normally assumes a tilted position when held by a stop means.
  • a pump unit comprised of a motor and a pump is pivotally mounted and also movable upward and downward on vertical guide means fixed in the catch basin so that as'the unit is raised or lowered it normally assumes a tilted position when held by a stop means.
  • the pump outlet conduit engages the inlet of a fixed discharge pipe in the sump and is moved into its coupled position therein by the downward gravitational force of pump unit itself.
  • the coupling action is quick, sure and fully automatic, requiring no manual manipulation or external power other than that required to raise the pump unit.
  • FIG. 1 is a view in side elevation of a self coupling pump installation embodying the principles of the present invention
  • FIG. 2 is a plan view of the pump installation shown in FIG. 1;
  • FIGS. 3 5 are enlarged fragmentary views in elevation and in section showing the coupling action of the pump nozzle with a receiver according to the present invention.
  • FIGS. 1 and 2 illustrate a typical catch basin installation utilizing a pump apparatus 10 embodying the principles of my invention.
  • abasin 12 such as the type used in sewage systems to accommodate overflow extends a pair of discharge or outlet tubes 14.
  • Each of these discharge tubes has a curved lower end inlet portion 16 that turns to a horizontal orientation and is supported just above the bottom of the basin by a suitable frame assembly l8.
  • Spaced from each discharge tube inlet is a vertical track structure 20 that-supports a movable submersible pump assembly 22.
  • this track structure comprises a pair of vertical parallel and spaced apart bars that are anchored at their lower ends in the floor vof the basin.
  • a sliding base support member 26 for the pump 22 is retained by and movable vertically on the track members 20.
  • this support member comprises a rigid plate with lugs or flanges 30 and 32 that extend at right angles from locations near the side edges of the plate and near its upper and lower ends respectively.
  • Extending outwardly from each lug at a right angle thereto is another flange 34 that is spaced from and forms a channel 36 with the plate 28 and there are pairs of aligned channels on opposite sides of the plate.
  • the submersible pump assembly 22 is a self contained unit which includes an upper drive motor section 38 that receives power through a cable at its top and a lower pump section 40.
  • the latter has a central inlet opening 42 and an outlet nozzle 44 that extends tangentially from one side of the pump section in the conventional manner.
  • Extending from the pump section is a support bracket 46 comprised of two lug members.
  • a pin member 48 extends through aligned bearings in the two lug members and is journaled at opposite ends in the lower flanges 32.
  • Pivotally connected to a similar pin member 50 journaled in the upper flanges 30 is a bandlike stop member 52 which holds the pump assembly when it tilts a predetermined amount.
  • Attached to the upper pin member 50 or to the upper flanges is a chain 54 which is connected to a suitable lifting means (not shown) situated above the catch basin.
  • the pump outlet nozzle 44 has a cylindrical shape and is provided with an annular sealing member 56.
  • This sealing member may be a conventional O-ring type which is seated in an annular groove near the end of the nozzle.
  • a self coupling pumping apparatus comprising:
  • said pump having an extended outlet nozzle; a base support means slidably connected to said vertical guide means for up and down movement;
  • stop means for holding said casing in a tilted position
  • said pump outlet nozzle engages said discharge end portion and slidably enters therein into a coupling position as said casing continues to lower and simultaneously pivots upwardly from its tilted position.
  • the pumping apparatus as described in claim 1 including an annular sealing means mounted near the end of the pump nozzle.
  • said base support means comprises a member with projections along its opposite sides forming channels to receive said vertical guide means, a first pin means near the lower end of said member attached to said pivotally connecting means extending from said casing, and a second pin means for retaining said stop means near the upper end of said member.
