Be in transmission connection by the first insulating case and the second insulating case between this connection rotating shaft and this output revolving shaft, first insulating case and the second insulating case form secondary insulating structure, once the electric leakage of motor therein, two layers of insulation material is separated with between connection rotating shaft and output revolving shaft, electric current cannot be delivered on connection rotating shaft at all, thus blocked the possibility that electric current contacts with the water in pond, improve the security performance in pond.
Among one preferred embodiment: this first insulating case adopts the mode of injection moulding to encase the end of this connection rotating shaft.
Among one preferred embodiment: this second insulating case adopts the mode of injection moulding to encase the end of this output revolving shaft.
Among one preferred embodiment: this second insulating case encases this first insulating case.
Among one preferred embodiment: a standstill locking pin passes radially through this first insulating case and this connection rotating shaft; Another standstill locking pin passes radially through this second insulating case and this output revolving shaft.
Among one preferred embodiment: be connected together by screwed lock between this first insulating case and this second insulating case.
Among one preferred embodiment: described connection rotating shaft is metalwork.
Among one preferred embodiment: described connection rotating shaft is working of plastics.
A kind of Water-pumping motor with insulation function, comprise output revolving shaft and impeller, also comprise connection rotating shaft, this impeller is arranged on one end of this connection rotating shaft, this connection rotating shaft is working of plastics, together with being in transmission connection by insulating case between this output revolving shaft with this connection rotating shaft, this output revolving shaft and this connection rotating shaft synchronous axial system.
This connection rotating shaft is working of plastics, connection rotating shaft and insulating case form secondary insulating structure, once the electric leakage of motor therein, because insulating case and connection rotating shaft are all insulators, electric current cannot be delivered in the middle of pond at all, thus blocked the possibility that electric current contacts with the water in pond, improve the security performance in pond.
Among one preferred embodiment: this insulating case adopts the mode of injection moulding to encase the end of this connection rotating shaft and the end of this output revolving shaft.
