Abstract

Apparatuses and methods comprising a cementing head comprising a stationary body comprising a toothed ring; a rotating body disposed below the stationary body, the rotating body comprising an armature disposed inside the toothed ring; a battery disposed on the rotating body; and a wire connected to the armature and the battery.

Claims

1. A cementing head comprising:

a stationary body comprising a toothed ring;

a rotating body disposed below the stationary body, the rotating body comprising an armature disposed inside the toothed ring;

a battery disposed on the rotating body; and

a wire connected to the armature and the battery.

2. The cementing head of claim 1, further comprising at least one torque converter disposed on the rotating body.

3. The cementing head of claim 2, wherein the torque converter is electrically connected to the battery.

4. The cementing head of claim 2, wherein the torque converter is electrically connected to the armature.

5. The cementing head of claim 2, wherein the torque converter is electrically connected to the battery and the armature.

6. The cementing head of claim 1, further comprising a swivel disposed on the armature, wherein the wire is connected to the swivel.

7. The cementing head of claim 1, further comprising a heat jacket disposed over the battery.

8. The cementing head of claim 1, further comprising a radio frequency receiver/transceiver disposed on the rotating body.

9. The cementing head of claim 1, wherein the toothed ring comprises a plurality of magnets.

10. The cementing head of claim 6, wherein the armature comprises a coil of wire.

11. A cementing head comprising:

a stationary body comprising an armature;

a rotating body disposed at least partially inside the armature;

a battery disposed on the rotating body; and

a wire connected to the armature and the battery.

12. The cementing head of claim 11, further comprising at least one torque converter disposed on the rotating body.

13. The cementing head of claim 12, wherein the torque converter is electrically connected to the battery.

14. The cementing head of claim 12, wherein the torque converter is electrically connected to the armature.

15. The cementing head of claim 12, wherein the torque converter is electrically connected to the battery and the armature.

16. The cementing head of claim 11, further comprising a heat jacket disposed over the battery.

17. The cementing head of claim 11, further comprising a radio frequency receiver/transceiver disposed on the rotating body.

18. The cementing head of claim 11, wherein the rotating body comprises a plurality of magnets.

19. A method of generating electrical power, the method comprising:

disposing a cementing head on a well head, the cementing head comprising a rotating body, an armature, a stationary body, and a battery;

actuating the rotating body;

generating an electrical voltage in the armature; and

transferring the electrical voltage from the armature to the battery.

20. The method of claim 19, further comprising:

transferring the electrical voltage to a torque converter; and

actuating a cementing valve on the cementing head.
