Abstract

An apparatus for supporting an object at a controllable depth within a fluid features buoyant and ballast devices connected to a device for supporting the object. The opposing buoyant and gravitational forces acting on the support device cause it to maintain a generally constant orientation in the fluid and recover from deviations therefrom. The buoyant device has a variable buoyancy that can be controlled in order to control the depth at which the object is supported. A
control device allows the user to raise, lower or maintain the vertical position of the object within the fluid.

Claims (21)

1. An apparatus for supporting an object at a controllable depth within a body of water, said apparatus comprising:

a buoyant device having variable buoyancy with respect to the liquid;

a control device connected to the buoyant device and operable to control the buoyancy thereof;

a ballast device having a density greater than the water; and a support device connected to the buoyant and ballast devices for supporting the object.
2. The apparatus according to claim 1 in combination with the object wherein the object comprises a submersible pump for pumping water out of the body of water.
3. The apparatus according to claim 2 wherein is the submersible pump is operably connected to a power source located outside the body of water.
4. The apparatus according to claim any one of claims 1 to 3 wherein the buoyant device comprises an expandable buoyant member and a fixed protective housing, the buoyant member providing the variable buoyancy of said buoyant device and being contained within the protective housing.
5. The apparatus according to claim 4 wherein the protective housing has at least one opening therein through which water can pass into and out of said housing.
6. The apparatus according to claim 5 wherein the at least one opening in the protective housing is covered with at least one screen to prevent entry of objects larger than holes in said at least one screen into said housing.
7. The apparatus according to any one of claims 4 to 6 wherein the protective housing is openable for access to the buoyant member contained therein.
8. The apparatus according to any one of claims 1 to 7 wherein the ballast device comprises a container to and from which material can be added and removed respectively to vary the density of the ballast device.
9. The apparatus according to any one of claims 1 to 8 wherein the support device comprises an enclosure member within which the object can be contained.
10. The apparatus according to claim 9 wherein the enclosure member has at least one opening therein through which water can pass into and out of said housing.
11. The apparatus according to claim 10 wherein the at least one opening in the enclosure member is covered with at least one screen to prevent entry of objects larger than holes in said at least one screen into said housing.
12. The apparatus according to any one of claims 9 to 11 wherein the support device comprises an enclosure member within which the object can be contained, said enclosure member being openable for access to the object.
13. The apparatus according to any one of claims 1 to 12 wherein the buoyant device comprises an inflatable member and the control device comprises a mechanism for transferring gas to and from said inflatable member.
14. The apparatus according to claim 13 wherein the control device further comprises a pressure gauge operably connected to the inflatable member for measuring gas pressure therein.
15. The apparatus according to claim 13 or 14 wherein the control device further comprises a release valve operably connected to the inflatable member for releasing gas therefrom.
16. The apparatus according to any one of claims 13 to 15 wherein the control device further comprises a shut-off valve operably connected between the mechanism and the inflatable member for selectively blocking the transfer of gas.
17. The apparatus according to any one of claims 13 to 16 wherein the mechanism comprises an air pump.
18. The apparatus according to any one of claims 13 to 17 wherein an auxiliary valve is connected the inflatable member for selectively providing an additional passageway through which gas can exit said inflatable member.
19. The apparatus according to any one of claims 1 to 18 wherein at least a portion of the control device housed within an openable casing for protection.
20. The apparatus according to claim 19 wherein the openable casing is lockable to prevent unauthorized access to at least part of the control device housed therein.
21. The apparatus according to any one of claims 1 to 20 wherein the control device is remotely positioned with respect to the buoyant, ballast and support devices for operation for operation of said control device from outside the body of water.
