An apparatus and process for lifting heavy objects by capturing mechanical work from the buoyant energy of liquid displacement. The apparatus comprises one or more bodies of liquid, collapsible liquid-displacement displacement vessel, and lifting force transfer means to the object, in use, the weight of the object to be lifted is secured onto the lifting platform and leveraged by the force transfer means to draw gas into the displacement vessel. Once the displacement vessel is full of gas, it will reverse the force transfer means to lift the object to the top of the liquid. Once the lifted object is secured at the elevated position, a gas release valve releases the gas and the displacement vessel collapses and sinks back down to the bottom of the liquid and the process can be repeated as necessary.
An apparatus for lifting heavy objects utilizing energy from liquid displacement, composed of one or more of the following:
The apparatus of claim #1 further comprising a collapsible displacement vessel submerged within the liquid that has the components of (a) an upper section that has legs, columns, or a support system for reaching from the bottom of the body of liquid up to the upper section. The upper section also has a gas input corral and a gas outlet valve and the upper portion of a retracting system for collapsing the displacement vessel. The upper section is also connected to the top part of the mid-section, and (b) a mid-section comprised of a gas chamber, bellows, or bladder for the purpose of inflating with gas to displace liquid and collapsing to dispel the gas, and (c) a lower section comprised of a platform or apparatus that is connected to the bottom of the mid-section and is free to move from the top down to the bottom stoppers of the legs, columns, or support system for reaching from the bottom of the body of liquid up to the upper section. The lower section also has the lower portion of a retracting system for collapsing the displacement vessel. The bottom section is also connected from the bottom side to the mechanical transfer means by which the heavy objects are lifted.
The apparatus of claim #2 further comprising a mechanical transfer comprising a cable and pulley system, lever, gear, pump, shaft, or line connected to the collapsible displacement vessel apparatus and able to lift or lower depending on the need, serving the purpose of either pulling the bottom of the gas chamber, bellows or bladder part of the displacement vessel apparatus in order to draw gas in to inflate it, or once inflated and floating upward, the mechanical transfer will be pulling the lifting platform.
The apparatus of claim #3 further comprising a lifting platform or apparatus connected to the other end of the mechanical transfer which serves the purpose of securing the heavy objects. throughout the elevation process.
The apparatus of claim #4 further comprising a sensor and trigger that allows for the lifting platform to initially descend in order to serve as a force to draw gas into the collapsible displacement vessel and inflate it.
The apparatus of claim #5 further comprising a sensor that senses when the displacement vessel is inflated to its optimal level and sub sequentially release the lifting platform to allow the submerged, inflated chamber, bellows or bladder to cause the lifting platform to ascend.
The apparatus of claim #5 further comprising a locking system to align and hold the lifting platform to the elevated dismount area once the lifting platform has elevated to its desired height for the purpose of allowing the heavy object being lifted to dismount from the lifting platform
The apparatus of claim #7 further comprising a sensor and trigger to open the gas release valve that allows the displacement vessel to expel its gas and deflate to its collapsed state
The apparatus of claim, #8 further comprising a retracting system that allows the displacement vessel to collapse to its gasless state in order to descend down to the bottom of the body of liquid to its initial position.
An apparatus for utilizing energy from buoyancy force for the purpose of elevating heavy objects, said apparatus comprising a large body of liquid for the purpose of that liquid being displaced to provide buoyant force;
A process or method for lifting objects whereby energy from buoyant force is utilized for the purpose of elevating heavy objects, said apparatus comprising one or more of the following:
