Integral contractors box for a submersible turbine pump

Abstract

The present invention provides a submersible turbine pump (STP) comprised of a manifold comprising an electrical cavity, a port above the electrical cavity, and a field wiring conduit through which electrical field wiring is brought into the electrical cavity and connected to the submersible turbine pump. The STP is further comprised of a removable plug adapted to be inserted into the port. When the removable plug is inserted into the port, the plug seals the electrical cavity. When the removable plug is removed from the port, access is provided to the electrical cavity.

1 . A submersible turbine pump, comprising: 
 a manifold, comprising: 
 an electrical cavity;  
 a port above the electrical cavity; and  
 a field wiring conduit through which electrical field wiring is brought into the electrical cavity and connected to the submersible turbine pump; and  
   a removable plug adapted to be inserted into the port, thereby sealing the port when inserted into the port and allowing access to the electrical cavity when removed from the port.    
     
     
         2 . The submersible turbine pump of  claim 1  further comprising an o-ring located between the port and the removable plug and sealing the port when the removable plug is inserted into the port.  
     
     
         3 . The submersible turbine pump of  claim 1  wherein the port is a female threaded port and the removable plug is a male threaded plug.  
     
     
         4 . The submersible turbine pump of  claim 1  further comprising: 
 a rubber bushing located within the field wiring conduit wherein the electrical field wiring passes through the rubber bushing before entering the electrical cavity; and    top and bottom plates adapted to adjustably compress the rubber bushing to provide strain relief to the electrical field wiring.    
     
     
         5 . The submersible turbine pump of  claim 4  further comprising a screw connected to the top and bottom plates such that rotating the screw controls a distance between the top and bottom plates, wherein the distance between the plates decreases when the screw is rotated in a first direction thereby compressing the rubber bushing and the distance between the plates increases when the screw is rotated in a second direction thereby uncompressing the rubber bushing.  
     
     
         6 . The submersible turbine pump of  claim 1  wherein the field wiring conduit is sealed.  
     
     
         7 . The submersible turbine pump of  claim 1  wherein the electrical cavity is explosion proof.  
     
     
         8 . The submersible turbine pump of  claim 1  wherein the manifold further comprises a second port above the electrical cavity, and the submersible turbine pump further comprises a second removable plug adapted to be inserted into the second port, thereby sealing the second port when inserted into the second port and allowing access to the electrical cavity when removed from the second port.  
     
     
         9 . The submersible turbine pump of  claim 8  further comprising a capacitor located within the electrical cavity and the capacitor is accessible when the second removable plug is removed from the second port.  
     
     
         10 . The submersible turbine pump of  claim 1  wherein the manifold further comprises: 
 at least one additional electrical cavities;    at least one additional port above the at least one additional electrical cavity; and    at least one additional field wiring conduit through which additional electrical field wiring is brought into the at least one additional electrical cavity and connected to the submersible turbine pump.    
     
     
         11 . The submersible turbine pump of  claim 10  further comprising at least one additional removable plug adapted to be inserted into the at least one additional port, thereby sealing the at least one additional port when inserted into the at least one additional port and allowing access to the at least one additional electrical cavity when removed from the at least one additional port.
