Transformer in-situ inspection vehicle with a cage hull

1. An inspection device for use in a fluid container, comprising:

at least one thruster;

at least one ballast device;

a cage which carries said at least one thruster and said at least one ballast device, said cage comprising a plurality of bars, each of said bars arcuately formed around an opening wherein said opening forms a cage cavity to carry said at least one thruster and said at least one ballast device; and wherein the plurality of bars includes:

a first set of at least two bars formed around the opening and oriented in a first direction in substantially parallel planes to one another; and

a second set of at least two bars formed around the opening and oriented in a second direction in substantially parallel planes to one another.

2. The device according to claim 1 , wherein said at least one thruster and said ballast device are carried within said cage cavity.

3. The device according to claim 1 , wherein said first and second directions are substantially perpendicular with one another.

4. The device according to claim 1 , wherein said first and second set of at least two bars intersect with one another at intersection points, wherein said intersection points and adjacent bars form the cage opening.

5. The device according to claim 4 , wherein said cage opening is contiguous with said cage cavity to allow fluid in the fluid container to flow through said cage when said at least one thruster is activated.

6. The device according to claim 4 , wherein each said bar is a slat that has a leading edge opposite a trailing edge, wherein said leading edges form a cage exterior.

7. The device according to claim 6 , wherein each said slat has opposed surfaces connecting said leading edge to said trailing edge.

8. The device according to claim 7 , wherein said at least one thruster has a thrust vector wherein said opposed surfaces are oriented with said thrust vector.

9. The device according to claim 1 , wherein each said bar is a slat that has a leading edge opposite a trailing edge, wherein said leading edge and said trailing edge are connected by opposed surfaces which are oriented in a same direction as a thrust vector generated by said at least one thruster.

10. The device according to claim 1 , wherein said first set of at least two bars and said second set of at least two bars intersect with each other at an intersection point.

11. The device according to claim 1 , wherein said cage is substantially spherical.

12. An inspection device for use in a fluid comprising:

at least one component included from the following: a sensor, control electronics and/or a camera;

a cage having a cavity which internally carries said at least one component, said cage having a plurality of bars with openings therebetween, the plurality of bars formed in an arcuate shape to define the cage cavity internal thereto, wherein at least two of the plurality of bars are oriented in parallel planes relative to one another, and wherein the openings allow fluid to flow therethrough and around said at least one component;

at least one thruster for propelling the cage through the water;

a battery compartment structured to carry a power source useful to provide power to the at least one thruster;

wherein said plurality of bars comprise a first bar oriented in a first direction, a second bar oriented in a second direction, and wherein said first bar is connected to said second bar at an intersection point; and

wherein each of said first bar and second bar have a circular body.

13. The device according to claim 12 , wherein a portion of said plurality of bars are oriented in a first direction, the device further comprising:

at least one interconnecting bar to connect adjacent bars oriented in said first direction.

14. The device according to claim 12 , wherein each of said plurality of bars have a body opening therethrough.

15. The device according to claim 14 , wherein at least one of said plurality of bars is a slat having a leading edge opposite a trailing edge.

16. An inspection device for use in a fluid comprising:

at least one component included from the following: a sensor, control electronics and/or a camera;

a cage having a cavity which internally carries said at least one component, said cage having a plurality of bars with openings therebetween, the plurality of bars formed in an arcuate shape to define the cage cavity internal thereto, wherein at least two of the plurality of bars are oriented in parallel planes relative to one another, and wherein the openings allow fluid to flow therethrough and around said at least one component;

wherein each of said plurality of bars have a circular body which has a body opening therethrough, and wherein at least two of said circular bodies have a different outer diameter;

wherein at least one of said plurality of bars is a slat having a leading edge opposite a trailing edge; and

wherein said at least one component further includes a thruster which generates a thrust vector which is aligned in a same orientation as said leading and trailing edges.

17. The device according to claim 15 , wherein said at least one component further includes a thruster which generates a thrust vector which is aligned in a same orientation as said leading and trailing edges.

18. The device according to claim 12 , wherein each of said plurality of bars have a circular body, and wherein at least two of said circular bodies have a different outer diameter.
