The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further explain.
Fig. 1 is the structural representation of single core cable oil field deep well dredging instrument of the present invention, and said drifting appearance comprises with lower component:
Drifting appearance upper end is provided with cable plug 3,
The top of drifting appearance is provided with battery compartment 4,
The middle part of drifting appearance is provided with wiring board 5,
The bottom of drifting appearance is provided with main motor 6,
Drifting appearance lower end is provided with drifting drill bit 7;
The cable jacket steel wire floor 2 of single core communication cable 1 is electrically connected through cable plug 3 and drifting appearance shell, and the cable core of single core communication cable 1 is electrically connected through cable plug 3 and wiring board 5;
Be provided with the low-voltage rechargeable battery set that electric power is provided for wiring board 5 in the battery compartment 4, the negative pole of low-voltage rechargeable battery set and drifting appearance shell are electrically connected, and anodal positive terminal with wiring board 5 is electrically connected;
