Manually portable electric bilge pump with a rechargeable battery

Abstract

A manually portable bilge pump having a motor powered by a rechargeable battery, enclosed in a detachable battery housing, has an intake conduit extending downward to the deepest region of a vessel's bilge and a discharge conduit preferably extending overboard or to the galley sink for delivering pumped bilge water outside the vessel.

1 . A manually portable bilge pump for removing water from the bilge of a vessel, comprising in combination 
 An electric motor-driven pump adapted for submersible operation underwater in a sump or the bilge of a vessel, to produce an effluent discharge stream,    An elongated hollow intake conduit, having an upper proximal end, and a submersible lower distal end providing anchored support for the pump, and operatively connected to receive the pump's discharge stream,    A greatly elongated flexible hollow discharge conduit having a proximal end firmly anchored to the proximal end of the intake conduit and a remote open distal end,    A hand-grip mounted on the elongated intake conduit near its proximal end adapted for manual support of the combined assembly by the user,    And a rechargeable battery enclosed in a battery case mounted on the hand-grip with the battery operatively connected to the motor-driven pump, and removable for disconnecting and periodic recharging of the battery,    whereby the combined assembly conveniently maneuvered and supported manually by a user positioned above the bilge water, while the bilge pump is submerged in the bilge water while pumping it up the intake conduit and into the flexible discharge conduit when its open distal end is positioned to discharge the pump's effluent stream at a desired location remote from the bilge being pumped.    
   
   
       2 . The manually portable bilge pump defined in  claim 1 , wherein the elongated hollow intake conduit is substantially rigid.  
   
   
       3 . The manually portable bilge pump defined in  claim 1 , wherein the flexible hollow discharge conduit incorporates a resilient helical reinforcing wire spring.  
   
   
       4 . The manually portable bilge pump defined in  claim 1 , further including a ballast weight anchored to the remote open distal end of said flexible hollow discharge conduit, thereby stabilizing it against undesired random movements.  
   
   
       5 . The manually portable bilge pump defined in  claim 1 , wherein said hand-grip incorporates a stand-off column to which said battery case is mounted.
