1. An actuation system for pumping fluids out from under ground, the actuation system comprising:
a pump jack comprising a sucker rod configured to reciprocate into and out of an oil well drilled into the ground; a base; a wheel rotatably attached to the base; a horse head fixture fixed to the wheel; one or more reigns attached to the horse head fixture and attached to the sucker rod, such that rotation of the wheel in a first direction raises the sucker rod and rotation of the wheel in a second direction lowers the sucker rod; a cable attached to the wheel and configured to be wound on and unwound from the wheel as the wheel rotates; a container attached to the cable, such that rotation of the wheel in the first direction lowers the container and rotation of the wheel in the second direction raises the container, wherein the container comprises at least one outlet hole formed therethrough and one inlet hole formed therethrough; equalizing weights fixed to the cable and weighing less than a weight of the reciprocating element; a flapper configured for covering the outlet hole in a first position and uncovering the outlet hole in the second position such that liquid may exit through the outlet hole; a frame fixed relative to the ground and above the container; a flexible line having a first end and a second end, the first end being attached to the frame and the second end being attached to the flapper and limiting an amount by which the flapper can be lowered relative to the frame, such that when the container is lowered past a predetermined point, the container pulls away from the flapper, placing the flapper in the second position; a reservoir configured to hold liquid and located beneath the container outlet hole; at least one pump located in the reservoir and configured to pump liquid out of the reservoir; and a hose fluidly connecting the pump with the inlet hole of the container. |
