Have you tried:

// application core (manager of managers) for paraview
pqApplicationCore* appCore = pqApplicationCore::instance();
// server manager model for querying items in the server manager
pqServerManagerModel* smModel = appCore->getServerManagerModel();
// get all the pqRenderView instances.
QList<pqRenderView*> renderViews = smModel->findItems<pqRenderView>();

The pqRenderView gives you access to the vtkSMRenderViewProxy and the 
QVTKWidget attached to it, as well as image capture routines.
