Cable storage drum with moveable CCU docking apparatus
Video inspection systems with moveable and dockable CCUs are disclosed. In one embodiment a video inspection system includes a tubular frame element, a camera control unit (CCU), and a docking apparatus mechanically coupled to the frame element so as to allow the CCU to rotate and/or be detached are attached via a user action.
1. A video inspection system, comprising:
a frame;
a push-cable;
a camera control unit (CCU) including a housing, electronics disposed in the housing for controlling operation of a camera head operatively coupled to the electronics, a display disposed in the housing for rendering images or video provided from the camera head, and a non-transitory memory for storing images or video provided from the camera head;
a cable storage drum enclosing the push-cable when retracted, the cable storage drum coupled to the tubular frame and including a slip-ring for operatively coupling CCU electronic input and output connections to the camera head; and
a docking apparatus mechanically coupled between the frame and the CCU to allow the CCU to rotate relative to the frame and the cable storage drum, about a rotational axis, responsive to a user action, and allow the CCU to be removably attached or detached, via a user-actuated latching mechanism, to the frame, wherein the docking apparatus includes a frictional element for restraining rotation of the CCU.
2. The system of claim 1 , wherein the CCU is partially engaged via a snap-action engagement to the frame.
3. The system of claim 1 , further including the camera head, and a push cable with connectors for mechanically and electrically coupling the push cable to the camera head and the CCU.
4. The system of claim 1 , wherein the latching mechanism includes one or more knobs rotatable on a release axis to release the CCU from attachment to the tubular frame.
5. The system of claim 4 , further comprising a latch indicator to indicate a release state or a locked state of the CCU responsive to a user action on the knobs.
6. The system of claim 3 , wherein the push-cable is disposed at least partially within an interior volume of the cable storage drum and the push-cable is operatively coupled to the CCU via the slip-ring.
7. The system of claim 6 , wherein the camera head is a self-leveling camera head.
8. The system of claim 1 , wherein a center of gravity of the CCU is centered at or proximate to a central movable axis of the cable storage drum.
9. The system of claim 1 , further comprising one or more handles disposed on at least one of the CCU, the docketing apparatus, or the frame, the handles being designed to be grasped by a user's hand for transportation of the system.
10. The system of claim 3 , further comprising a modular battery apparatus electrically coupled to the CCU to provide operational power for the electronics and the camera head.
11. The system of claim 3 , further comprising a counting device configured to determine and measure rotations of the cable storage drum to determine quantity of the push-cable dispensed from the cable storage drum and/or distance travelled by the camera head from the cable storage drum.
12. The system of claim 1 , further comprising a wireless communication device to send image or video data from the camera head or CCU to a remote communicatively coupled electronic device.
13. The system of claim 12 , wherein the wireless communication device comprises a mobile phone.
14. The system of claim 12 , wherein the wireless communication device comprises a Bluetooth device.
15. The system of claim 5 , wherein the release state and the locked state are indicated by different color bands.
16. The system of claim 1 , wherein allowing the CCU to rotate relative to the frame and cable storage drum further comprises allowing the CCU to be positioned relatively horizontal or vertical.
